Development Trend of Domestic Punch Industry Development

Development Trend of Domestic Punch Industry Development Trend of Domestic Punch Industry At present, the domestic punch press manufacturers of the basic characteristics of the punch there are two, one is rigid, which includes the longitudinal stiffness of the slider and the table of the arch and the elastic elongation of the rack; and lateral rigidity – eccentric load Horizontal shift of the lower slider. The second is the movement of the slider characteristics, including the vertical, parallelism, straightness, etc., have a great impact on the accuracy of the product. The accuracy of the product is not only with the punch, and materials, molds, lubrication and so on, can not only consider a certain factor. The accuracy of the thickness direction of the product is related to the longitudinal rigidity, while the deviation, bending or parallelism is related to the transverse rigidity and the characteristics of the motion profile. So to improve these characteristics drilling machinery, product accuracy can be improved, die life extension, production stability can be improved.

These characteristics of the punch must be taken into consideration when the press is selected in accordance with the forming method, the forming speed, and the productivity. Depending on the drive mechanism, the mechanical presses are: the most widely used crank press in stamping, the slowest toggle press near the bottom dead center, and the slow speed of the slider above the bottom dead center And has a high torque capacity of the connecting rod punch hydraulic busbar punching machine. In the case of forging presses, the crankshaft type punching machine is used in the case of forging productivity, and the toggle type punching press is used in the vicinity of the bottom dead center. If it is necessary to form or block forging at a high position, punch. In order to achieve non-cutting forming, the function of the punch is getting higher and higher. Stamping machinery is the development trend of high precision steel fabrication, high rigidity, the characteristics of the slider movement, intelligent, multi-directional movement, and even the direction of environmental protection.

Precision punching clutch running principle is: when the clutch oblique keys in the spring under the action of the flywheel into the corresponding wedge-shaped keyway to achieve the drive joints. In actual operation, the clutch control brake by opening and closing of the slider to determine the trip, the brake release, the punch cam mechanism began to work, the slider down, when any point brake tightened, the cam-controlled The axis will get an empty trip, the slider picks up. Precision punch press is an important part of the precision punching machine, which is installed between the flywheel and the crankshaft of the punch press plate Drilling Machine. The clutch and the brake are synchronized during the operation.

That is, the clutch is actuated, the brake is released, the clutch is released. Sub-action, brake lock. The clutch shaft comprises a clutch main body, a clutch oblique key, a clutch lever and a gland Drilling Machine for Sieve Plate, wherein the rotary shaft of the clutch oblique key and the clutch lever are respectively installed in the shaft hole of the clutch main body and the gland, The hook-like projections of the clutch slanted keys are opposed to the positions of the short arms of the clutch lever, and compression springs are provided in the spring holes of the bent column walls of the clutch body marking machine.

Precision high-speed press overload pump

Precision high-speed punch overload pump, for precision punch overload pump do not know if we have not learned in our usual work for the understanding of precision high-speed punch must be more welding of steel pipe, so that our usual work is very useful Ring Drilling Machine. Precision punch overload pump is one of its core components, which can detect the internal solenoid valve through the hydraulic cylinder pressure drill machine, when the pressure is insufficient, can quickly make up and maintain the normal high-speed stamping pressure; when the overload situation can be instant Release the pressure to protect the press mechanism and die life. Precision Punch Overload pump has the protection of mold, emergency stop in critical situations, card mode from the time to reduce the connection gap, sensing eccentric load and other five functions.

To use a good high-speed precision punching, to understand the working principle of overload pump is essential, my company in its machinery to do a detailed description: In this case, The actual use of precision high-speed presses, the overload pump on the pressure switch connected (ON), so that our high-precision presses in the state can be run. Indicates that there is overload protection, can be stamping. After the pump starts, due to the role of the initial pressure, overload the main valve to the right direction slightly. In this case, High-speed precision press cylinder oil pressure rose to set pressure above, the main valve to overcome the spring force to move to the right, open the main valve seal will be sent back to the high-pressure oil tank.

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 high-speed punch without the material running noise, which contains the motor noise, the impact of 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 angle iron drill, 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. 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 of the connecting rod in the reciprocating motion 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 Laser Cutting Robot, 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-connecting rod slide structure: connecting rod small head (ball head) and slider ball head seat; crankshaft journal and crankshaft tile; crank neck and connecting rod big bearing CNC Busbar Punching Machine. Due to production and commissioning errors and practical needs, there is a gap between the necessity of these components. The relative movement between components, from free movement to contact movement, inevitably bring 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.
