Does precision forging equipment affect the accuracy of the noise?

Precision punch noise According to the type of noise generated can be divided into no-load noise and load noise. No-load noise is a high-speed press no material running noise, which contains motor noise, running parts of the impact of noise, clutch and gear collision noise.

One of the most important source of noise is the impact of clutch and gear noise. Load noise is a high-speed press punching products generated when the noise, in the same high-speed press on the use of different stamping process (such as punching, drawing, bending) processing the same material noise is not the same. Precision punch motor noise. As a power source, the noise generated when the motor running, including motor windings of electromagnetic noise, aerodynamic noise and mechanical noise. Motor noise level is mainly the size of the motor power, speed. Electromagnetic noise of the motor, is generally caused by alternating electromagnetic field interaction excitation of the rotor and stator vibration. Electromagnetic noise is usually high-frequency noise punch 3d. Clutch noise. When the clutch is closed, the general high-speed punch will have a 'jingle' sound. This is the intermittent sound generated by the impact of the slider, the inertia force of the connecting rod in the reciprocating operation, and the centrifugal force of the rotational quality of the crankshaft. Clutch noise generated by the main factors are: Clutch closed by the size of the impulse, in a certain state of quality depends on the speed of high-speed punch impact speed; also contact with the stiffness and damping characteristics of the material itself. Clutch has two kinds of rigid and friction type, which friction in the small tonnage high-speed punch on the most widely used, the noise is generally high punch online, the noise is caused by a series of collisions. Noise of running parts of precision punching machine.

There are three pairs of friction pairs in the high-speed punch's crank-link slider structure: connecting rod small head (ball head) and slider ball head seat; crankshaft journal and crankshaft tile; crank neck and connecting rod big bearing. Due to production and commissioning errors and practical needs, there is a gap between the necessity of these components. The relative movement between components punch trump game, from free movement to contact movement, inevitably bring the collision, the greater the gap, the stronger the noise. In addition, the gap is fixed, the slider stroke the greater the number, the greater the noise. The aerodynamic noise of the motor is typically the cooling fan noise, which is the main noise source for most motors. High-speed punch mechanical noise mainly contains some rotating parts of the unbalanced force excitation generated noise and vibration generated when some parts of the noise.

Precision equipment load noise really annoying

Precision equipment load noise really annoying The causes of load operation noise are caused by tool and workpiece or stripper plate and blank impact hole punch, stamping process of twisting and punching. One punch stamping process of punching and torsional noise is the biggest noise.

1. Punching shear noise. Stamping process different, very different noise. Sheet blanking than bending, deep drawing noise. The punch press, pressure wave, flanging, bending, drawing and other forming process noise is small.

2. Punch noise. Torsional noise of the same punch press and punch parts thickness punch 360a2, hardness, geometry, hammering speed, die clearance and other factors, noise increases with increasing the amount of these values. Punch work, the punch and the plate and the discharge plate and blank impact impact greatly enhanced, with the impact of the impact speed also increased. The collision noise of the punch and the subsequent fracture sound of the material can be measured separately, and this measurement method has been implemented punch update. In the same punch, punching thick, hard material than the punching thin, soft material noise. For thick ductile sheets, the impact noise is the same as the fracture sound.

The use of precision equipment in the process will have the waste how to do it

Precision machinery and equipment used in the process of how the waste will have to do it Precision machinery and equipment in the process of waste will be how to do it Precision punching press because of its high precision, high utilization of materials, high production efficiency, easy to automate, the manufacturing industry to use the most punching equipment punch university rawalakot azad kashmir. Precision punch mainly by the upper and lower mold base and installed in the upper and lower mold base of the mold structure, the upper and lower die seat connected through the guide column, the upper and lower blocks along the column by moving up and down to achieve stamping and mold. But the actual use of precision presses, as the material stamping deformation, there will be waste generated, will affect the next process - forming the quality of stamping, to the next process unnecessary trouble will also affect the final product Surface accuracy and mold life, reduce material utilization.

The air blowing device can effectively clean the punch mold, and has the advantages of simple structure, high efficiency and can effectively improve the surface precision of the finished product. The precision air injection device consists of two air feed pipes, which are installed on the lower surface of the upper die holder and on both sides of the die on the upper die holder. The gas pipe has a jet section which is arranged along the front and back direction of the upper mold seat of the punching machine punch tv, and a plurality of gas pipes are arranged on the jet section downwardly, the upper end of the gas pipe is communicated with the air injection section of the gas transmission pipe, And a nozzle is arranged at the lower end of the air jet pipe, and the air nozzle is inclined in the mold cavity direction of the lower mold. Precision punch air blow device in the process of moving the material to the surface of the material blowing; out of the material can be carried out after the mold chamber hair; this mold can better die and the surface of the material to be cleaned in order to achieve The mold cavity and the surface of the waste material to remove, thereby improving the quality of finished products stamping and surface accuracy kangaroo punching anchor. In order to make the air blown better, the angle of the jet nozzles at the lower ends of the two adjacent nozzles of the precision punch presses are different, so that the mold cavity of the die holder on the die punch of the punch press can be blown in multiple angles, so as to further ensure the stamping of the finished products. Forming accuracy, mention the finished product quality.

How long does it take for a precision punch to change the mold?

Precision punch precision testing is an important part of the factory punch test punch update, here we give customers to C2N series - double crankshaft precision steel frame punch precision test table as an example for customers to show punch romaine, so that customers at a glance, really buy the rest assured. If customers need other types of punch precision test table, please contact our customer service and obtain directly.

Punching process, the first by the ring plate, die, punch and back plate compression material; then punch punching punching force applied to the punching force and anti-pressure should remain unchanged, continue to compress Blanking; blanking the end of the slider back, the precision punch is not synchronized to provide unloading force and the top pieces of force to achieve the discharge and the top pieces drain punch x and y. Precision punch press force and back pressure can be adjusted according to the needs of specific parts fine blanking process within a certain range, so to achieve the three fine blanking action, providing the best choice for five forces - precision punch. While the IPM precision punch for one of the king, it is recommended.

Precision punch press pipe connections

Precision punch press for the pneumatic clutch brake, the main punching power, driven by the main motor flywheel punch quilting zip bind, flywheel driven crankshaft, and the momentum generated, so in the actual operation process, stable, clean gas source is to ensure precision Punch stable performance of the fundamental. In the actual installation process, first close the air supply air shutoff valve kangaroo punch video, the punch air pipe and the air supply pipe connection, and then supply 0.5-0.7MPa of compressed air punch quilts, with special attention to the punch air pipe must be from Pneumatic piping at the back of the press (pipe diameter: 1 / 2B) is shown in the following table.

The required air pressure is 5kg / c㎡. But the distance from the air source to the assembly location must be within 5 meters. After the connection is completed, first of all, try to output air, check a part of the pipe there is no dust and sewage water retention, this can not be ignored, unclean, stagnant air will cause the solenoid valve malfunction, cylinder rust, Can easily lead to punch safety incidents. Next, switch the main valve and install the air intake port in the air connection hole.
