The process of installing a mold on a punch

December 26, 2016 · Posted in Uncategorised · Comment 

The process of installing a mold on a press 1) Before installation, make sure that the edge of the die is sharp and there is no crater on the edge of the die. If there is a chink or missing angle, first sharpen the knife. In this case, 2) Before the mold should be in the upper and lower mold between the pad into a piece of silicon steel to prevent the collision process due to injury blade. In this case, 3) In the mold before the punch drilling milling machine, use the Whetstone to the bottom and the top of the burr worn off, with a cloth to clean up the garbage. If there is burr or rubbish on the upper and lower surfaces of the mold Tapping Machine, it will cause the burr tolerance of the die. In this case, 4) Adjust the slide stroke to the appropriate position to press the upper mold, must ensure that the mold handle or mold frame, until the punch into the die 3 ~ 4mm, pressing the lower mold surface in the bottom of the slider close fit, Screw gently pressed. Then, adjust the slider up to remove the middle silicon steel sheet. Loosen the lower mold plate screw and adjust the slide plate clamp screw downwards. New die punching punch must enter the die 3 ~ 4mm, otherwise, there must be punch die or concave die burst. In this case, 5) raise the slider to the top dead center position, adjust the punch rod to stop the screw, to the appropriate elastic, and then idling a few times to observe the mold and punch the work of the institutions are normal. If there is no exception automatic girth welding machine, you can start production.

Punch – Precision Punch offer _ Pneumatic Punch wholesale factory Noise Reduction of Stamping Workshop In this case, Noise is the most important factor in occupational hazards of automobile stamping workshop plate bevelling machine. If the current pressing conditions, especially with the continuous application of automation technology, stamping production line faster and faster pace of production, resulting in more and more intensive noise. The average noise in the operation of the general stamping workshop is above 90dB (A), and some areas even reach 100dB (A) or more. Therefore, from the protection of staff hearing and build a green factory point of view, the stamping workshop must be noise control engineering. Precision presses In this case, Stamping line noise reduction engineering basic idea Automotive stamping workshop noise control means more generally have the following three kinds: In this case, 1, the use of low-noise production equipment, focusing on solving the problem of noise sources.

With the development of press technology, the use of servo presses instead of the traditional mechanical presses, stamping noise can be controlled at 75dB or less, to achieve very good results. In this case, 2 angle steel open, on the job management and workpiece processing technology to adjust. By rotating the way to reduce the operator affected by the noise of the time; the same parts using 5 processes than the 4-processing process to produce less noise. Precision presses In this case, 3, the isolation of noise transmission, reducing the reverberation time of the workshop. As the workshop reverberation for a long time, the sound attenuation is slow, so the sound source through reflection to the sound point of the noise is also more Structural steel fabricator, so we must use special media to cut off the noise transmission to reduce noise on the health of the operator . As the existing stamping line has been unable to equipment and technology on a wide range of changes, therefore, equipment, technology and the surrounding environment has been identified, the isolation of noise transmission line is the main means of punching noise reduction and basic ideas.

Such as low-conductivity materials metal fabrication

Punch | Precision Punch Model | Pneumatic Press – Shenzhen Punch Factory How to adjust the elasticity of punch gap tracking? In this case, Gap tracking actually refers to the conversion speed. The principle of frequency conversion is such that a sampling voltage is obtained from the discharge gap to control an oscillator whose frequency and voltage are nearly linearly changed, and the pulse outputted by it is directly used as the operation and feed start and stop signal of the controller, The feed rate is controlled by the gap voltage. Conventionally, tracking elasticity artificially changes the amplitude range of the sampling voltage supplied to the oscillator. In this case, Tracking and adjustment of the most fundamental principle is to obtain stable processing, as long as the stability of the inverter circuit in a wide range of automatic control, in general, the frequency adjustment on the panel to be placed where to be processed. However, under certain circumstances cutting efficiency and quality, with the frequency of high-speed is still a significant relationship.

In this case, Speed ​​adjustment method is: the selected pulse width, pulse, after the number of tubes, precision presses observed pulse source voltmeter and ammeter, frequency conversion speed adjustment will make the value of the table within a certain range of changes in the Current smaller range, adjust the follow-up will be more sensitive to the direction of rapid adjustment will have a relatively slow, slow and sensitive at the junction is more appropriate. It can be said to have been transferred to the sensitive but still able to normal processing position and then slightly to call back a little bit. In this case, This refers to the normal material, the normal thickness. For some special materials or ultra-thick processing, the frequency adjustment should be targeted. Such as low-conductivity materials metal fabrication, in addition to increasing the amplitude of high-frequency source, the sampling should also increase the starting voltage, and make the track loose. Large thickness of the processing, but also should make some slower frequency conversion cnc plate drilling machine, rather some no-load pulse, but also give enough clearance and restore the insulation time CNC Busbar bending Machine. Tracking too tight, to a certain extent make the discharge gap smaller, black and white plating

Punch tonnage is one of the reasons for the impact of precision punching The main factors affecting the tonnage of precision presses include the length of the perimeter of the part hole punch for metal, the thickness of the material, and the strength of the material. Plate area and stroke length is determined by the size and depth of the parts shape, as the daily production capacity is mainly used to calculate the punch stroke per minute and the number of presses required to press the number of units in order to meet the overall production needs.

Punch tonnage is the impact of precision punch is the reason

For this process, a short-stroke high-speed punching machine is required for the process of embryo-punching and punching. For the processes of molding and extension, it is necessary to use a process such as forming, stretching and the like to process the parts together Welding adjustable stand. Long stroke and slower punching presses are used in the process of stamping, embossing and embossing, etc. The short stroke punch with high energy is used at bottom dead center. Can be seen, the greater the punch press tonnage the higher the price, in this punch manufacturers to remind customers to buy punch when not blindly concerned about the price of punch CNC machine, and only choose their own punch is the best punch.

Precision punching bending processing generally use the A2-level punch, such as the accuracy of the workpiece, especially when the rebound is very strict requirements, the thickness allows a small error in the bending of phosphor bronze and other sheet metal parts, only the use of A1-level punch to achieve Required accuracy. Therefore, the workpiece material thickness of the different specifications than the punch is also important. Such as 2-level accuracy of the material in the bending when there is no problem on the accuracy of the case, the use of B2-level punch can get better results. However, such a sheet material sometimes mixed with thick and hard material, so that mold overload phenomenon, such as punch rigidity, may not produce deformation, but cause damage or deformation of the mold.

The motion of the punch slides and the straightness of the table are a serious measure of the accuracy of the static accuracy of the project in order to ensure a portable precision measuring tool that measures the common cylindrical steel tool to ensure that the 8093-6059 standard and the handling of steel cylindrical gauges The accuracy is usually an important item. The steel column gauge uses an area of ​​small punch to detect, in any direction can be measured, the price is low, can reach the customer’s website and other advantages, wear and accuracy of the fault can be used when the outer surface coating and polishing to precision Tests can be deceptive, depressing the cost of filling new purchased products. Cylindrical precision chamfer tool, according to the 8093-6059 specification, the vertical and shaft diameter must meet the 2 + (/ 200) standard, I mean the length of the cylinder. Therefore, the commonly used punch cylindrical table, the precision tolerance speculation as shown in the table below: Length () ‘vertical’ and ‘shaft diameter difference’ of the license () As the standard of the cylinder is measured angle punch, in use and maintenance the required burial, or cylindrical gauge relaxation, becomes a measurement error. Cylindrical gauges are a kind of measuring instrument that checks the requirements of important items boring drilling machine, and testers can use directional matching to ensure the accuracy of the measurement. I am here to carefully introduce the boring, cylindrical rules carefully in the core of the use and maintenance: 1, a good punch Du process measurement should pay attention to handling Cylindrical gauge due to the small size, easy to dump or collision. Although the cylindrical gauge is mostly empty stomach, but still has a great weight, in addition to the cylindrical gauge damage to flip, by measuring the workpiece or below the platform will be similar to the attack, so be sure to retain. 2, first rub the bottom of the cylindrical gauge at the bottom of the area is very small, but if the bottom is not clear and clean, and place the cylindrical surface of the platform is not clean, it will cause vertical error. The cylindrical gauges are long in length, because the dirtyness of the bottom causes errors that will be greater.
