Curved lever force amplification linear drive punching machine

Abstract

The invention discloses a bent lever force amplification linear driving punching machine, comprising a hollow base, a driving component, a bent lever and a punching head, wherein the driving component is arranged in the interior of the hollow base and carries out linear reciprocating motion in a horizontal direction, one end of the bent lever is connected with an output punch at the output end of the driving component through an articulation component I, the punching head is connected with the other end of the bent lever through an articulation component II, a bent lever fulcrum is arranged over the driving component, and a through hole for allowing the up-and-down swinging of the bent lever is formed in the upper surface of the hollow base, and meanwhile, a longitudinal guiding mechanism is arranged below the bent lever fulcrum on one side of the punching head and is used for allowing the punching head to carry out linear reciprocating motion in a vertical direction. The bent lever force amplification linear driving punching machine has the advantages that the center of gravity of a machine body in the whole punching process is reduced, so that an operation that the weight of a base needs to be specially increased in order to keep the stability of a machine tool in the prior art is avoided, and the manufacturing cost is saved; the defects of low punching precision and poor stability easily caused by the fact that an upper horizontal rack part is easy to shake left and right in the prior art are overcome.

Description

technical field [0001] The invention relates to a stamping machine, in particular to a crank lever force amplification linear drive stamping machine. Background technique [0002] At present, stamping machines are widely used in stamping and forming of electronics, communications, computers, household appliances, furniture, vehicles, (automobiles, motorcycles, bicycles) hardware parts, etc. At the same time, with the rapid development of the economy and the improvement of people's living standards, More demands are placed on the punching machine. Traditional punching machines mainly include manual punching machines, mechanical punching machines, hydraulic punching machines and pneumatic punching machines. However, manual punching machines have low work efficiency and low pressure, and are suitable for manual processing such as small holes, paper and leather; mechanical Type punching machine, through mechanical transmission, has high speed, high efficiency and large tonnage,...

AI Technical Summary

Problems solved by technology

[0007] Preferably, during the entire stamping process, the stamping punch is located between the fulcrum of the curved lever and the driving part, which solves the shortcoming of poor vertical stability in the prior art, thereby further improving the stability of the stamping process sex
