Problems solved by technology

[0004] However, when the stamping machine is working, due to factors such as assembly accuracy, inertia, temperature and humidity, the repeated positioning accuracy of the bottom dead center of the slider is low during stamping, which cannot meet the stamping requirements of high-precision parts.

Abstract

The invention discloses a lever type punching machine which comprises a lathe bed, a working table, a crankshaft, a first connecting rod, a lever mechanism, a second connecting rod, a sliding block, and a motor assembly for driving the crankshaft to rotate. The crankshaft is rotatably connected to the upper end of the lathe bed; the first connecting rod is rotatably arranged on the crankshaft in asleeving way; one end of a swing arm of the lever mechanism is rotatably connected with the first connecting rod; the other end of the swing arm of the lever mechanism is rotatably connected with theupper end of the second connecting rod; and the sliding block is fixedly connected to the bottom part of the second connecting rod. An adjusting mechanism is used for adjusting the height of a supporting point of the lever mechanism, or adjusting the distance between the axis, connected with the crankshaft, of the first connecting rod and the axis, connected with the swing arm, of the first connecting rod, or adjusting the distance between the bottom part of the second connecting rod and the axis, connected with the swing arm, of the second connecting rod.

Description

technical field [0001] The invention relates to the technical field of punching machines, in particular to a precision lever type precision punching machine. Background technique [0002] The existing punching machine is designed to directly use the crankshaft or eccentric gear to drive the movement of the slider. This driving method requires a large driving force to achieve the punching purpose and consumes a lot of electricity. [0003] Chinese patent "201610075621 precision lever punching machine tool" discloses a lever punching machine tool, which uses the combination of eccentric block and swing arm to drive the slider, which requires less power under the same impact force and saves electric energy; the swing arm shaft of the swing arm The side close to the transmission link forms a lever, and a relatively large output power can be obtained under the action of a small input power, which further saves power consumption. [0004] However, when the stamping machine is wor...
