High - speed precision punch precision press security protection devices

High-speed precision punch Photoelectric protection device: also known as photoelectric protector, safety light curtain, safety grating, etc., the photoelectric protection device is through a group of infrared light beam to form a protective grating, when the grating is blocked, the photoelectric protection device sends a signal, Potentially dangerous machinery and equipment to stop working in order to reduce the operating personnel in the work environment the possibility of injury, the effective protection of the personal safety of workers punch recipes. High-speed precision punch and mechanical equipment to protect the operator's personal safety. Its security level requirements, mainly for forging industry, automobile manufacturing, electrical and electronic manufacturing industry and other areas of personal safety testing.

1. Photoelectric safety device: the principle is to use emitter and receiver to form one or more beam grating, the high-speed precision punch operator and the danger zone isolated, if the operator of a part of the body into the danger zone, the light is Cut off, the issue of electrical signals, the electrical signal amplified by the slider control circuit with the chain, so that the slider stop running.

2. Two-hand button protection: This is only a manipulator's hands while pressing the two buttons punch 325.2 specs, the slider only movement, when the high-speed precision punch to reach the next dead point before the slide, if halfway open any switch, High-speed precision press slide will stop movement of the protection device. This high-speed precision punch press is simple, safe and reliable, in the larger tonnage of the punch, because the high-speed precision punch itself stroke frequency is low, the impact of yield is not significant, the effect can still be satisfying. But the higher the frequency of the small tonnage punch, but because of the use of too much trouble and less use. When the high-speed precision punch equipment equipped with safety devices punch trump game, be considered a standard high-speed precision punch products, can be put into use.

Specification for high - speed precision punch presses

High-speed precision punch production rules: As high-speed presses with fast speed christmas punch quilt pattern, pressure characteristics, the use of punching for blanking, molding must comply with certain safety regulations. 1. Install the mold must be open to the bottom dead point slider, closing height must be correct, try to avoid eccentric load; mold must be firmly secured, and after pressure test. 2. Exposed to the press outside the transmission components, must install a protective cover, prohibit the removal of protective cover in the case of driving or testing. 3. Work to concentrate attention, is strictly prohibited hand and tools and other objects into the danger zone punch quest characters.

Small pieces must use special tools (tweezers or feeding mechanism) to operate. Die stuck blank, only allowed to use tools to escape. 4. Before driving, check whether the main fastening screw loose, the mold with or without cracks punch quotes xml, control mechanism, automatic stop device, clutch, brake is normal, the lubrication system with or without oil blockage. If necessary, open the empty test The company adhere to the 'scientific management, and carefully developed; quality and efficient, compliance about re-letter' quality, and continuously improve the quality of the staff awareness and quality of work, a clear quality objectives and systems to ensure that the advanced nature and reliability in the market competition In the dominant position. Welcome customers to buy, and to undertake special needs of customers specifications products. IPM company's main products: high-speed precision presses, precision presses, pneumatic presses, sheet metal presses, forging press.

Structural Characteristics of Crankshaft of High - speed Precision Press

High-speed precision punch crank shaft structure characteristics, high-speed precision punch is a crankshaft punch, the crankshaft as the active part, the crankshaft rotation into the high-speed precision punch slide up and down reciprocating linear motion punch quilting zentangle, crankshaft The connecting rod is connected with the big head hole of the connecting rod, the small head hole of the connecting rod is connected with the slide block kangaroo punches man, the upper mold is arranged on the slide block, the lower mold is fixed on the lower worktable cushion plate, the slider drives the upper mold relative to the lower mold movement, On the die between the material to achieve stamping, so the crank shaft structure in the application of high-speed precision punch has a pivotal role.

The high-speed precision punch crank shaft to really run to use, the crank shaft must be installed on the drive gear and connected to the feed device on the pinion, the traditional drive gear and pinion fixed way: first set in the punch crankshaft And the corresponding key is set on the driving gear and the pinion, the positioning is carried out first, and then the connection between the crank shaft and the driving gear and the pinion is stepped, and the baffle is mounted on the crank shaft by bolts The drive gear and pinion fixed, in this way, the installation of the pinion, demolition, maintenance is very troublesome, time-consuming and laborious, affecting work efficiency. High speed precision punching machine In response to this problem, a high speed precision punching machine is designed with a novel crank shaft structure consisting of a crank shaft, a driving gear and a pinion, in which the driving gear and the pinion are sequentially mounted on the crank shaft, The rear part of the gear is connected with the feeding device at the same time, and a groove is arranged on the crank shaft at the rear part of the pinion.
The pinion is fixed by a high-speed precision punching machine at a circumferential position of the outer end of the connecting portion of the crank shaft and the pinion punch quotes, and a retainer is stuck in the groove so that the pinion is fixedly mounted, demolished and repaired Convenient, simple, and save time and effort, improve work efficiency.

High - speed punch operating inertia force

When the inertia force generated by the crank slider mechanism is much larger than that of the conventional punching machine punch through, the high-speed punching machine operates so that the high-speed punching machine generates vibration noise pollution and reduces the forming precision of the stamped parts. Therefore, the high-speed punch inertial force balance is very important. After careful study found that Jinde in the slider rail vertical force and horizontal force and force on the crankshaft bearing end performance is the high-speed press punch inertia force generated vibration. In general, the inertial force amplitude than the slider weight 20 times, so the punch vertical inertia force is greater than the total weight of the punch, so the large inertia force, the normal stamping production punch can have a very serious impact. In order to reduce the inertia force, increase the inertial force balance effect, reduce the quality of rotating parts and reciprocating motion. Since the high-speed reciprocating slide block is the main source of inertial force, the slider mass design is as small as possible while ensuring strength.

The dynamic balance device adopts advanced, adjustable, easy to maintain four points. Due to the inertia force of the high-speed punch is too large, it's too large, the slider speed is too high, pneumatic seals can not afford, the upper and lower chamber of the dynamic balancing cylinder needs frequent exhaust, no suitable pneumatic valve to meet the fast Switching frequency, therefore, the inertial force balance method can not be used for high-speed presses. The inertia force of the crank slider mechanism consists of three parts: the centrifugal inertia force generated by the rotation of the crankshaft, the reciprocating inertia force generated by the reciprocating motion of the sliding block and the inertia force generated by the planar motion of the connecting rod best five finger death punch quotes. The inertial forces generated by the plane motion of the connecting rods are the most complex. This project converted the mass equivalent to the hinge point of the connecting rod and the crank pin according to the static equivalent condition using a double mass substitution method, and then combined the rotary inertia force with the crankshaft. In addition punch quotes xena, the project is also equipped with a special dynamic vibration protection device, combined with spring to prevent vibration of the news.
