Problems solved by technology

But, because the slide block that slides up and down is installed in the middle part of the fuselage, the middle part of the slide block is leaky, the cam is installed in the leaky place, and the drive shaft is installed between the cam and the main gear, and the upper and lower parts of the slide block are equipped with cams matching the cam. The upper wheel of the slider and the lower wheel of the slider, the cam and the upper wheel of the slider and the lower wheel of the slider are in mirror image contact of two arcs, that is, line contact, resulting in a greatly weakened bearing capacity and low production efficiency

Abstract

The invention discloses a articulated concave-arc passive body cam punch press, belonging to the technical field of machine tools, comprising a bed and a motor, the motor is fixed on the bed, and is characterized in that it also includes a box body, which is sequentially installed with a friction clutch, Reducer, cam mechanism and friction brake. The cam mechanism includes a cam disc, a camshaft, a concave arc receiver, a punch sleeve and a punch shaft. The concave arc receiver is hinged to the punch shaft, and the cam disc and the concave arc receiver slide. Contact, there is a spring fixed between the bed and the punching shaft, and the cam disc includes the top dead center arc surface, the stamping unloaded arc surface, the stamping load arc surface and the return arc surface, the top dead center arc surface, the stamping unloaded arc surface, the stamping The load arc surface and the return arc surface are sequentially connected to form a closed loop. In the present invention, the arc surface of the cam disc and the concave arc affected body is coaxially combined with the same radius, which is surface contact, and is hinged between the concave arc affected body and the punching shaft, thereby ensuring the conversion and inheritance of large loads, thereby improving Carrying capacity, improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a hinged cam punch with a concave arc receiver. Background technique [0002] Stamping is an important category in the metal processing industry. Stamping processing has the advantages of good manufacturability, good operability, high material utilization rate and high production efficiency. Stamping machine tools are mainly divided into two categories, one is hydraulic machine tools, which use electric oil pumps to pump pressure oil to drive cylinders to drive molds to punch workpieces. Compared with electromechanical punching machines, hydraulic machine tools have the advantages of stepless speed regulation and good punching performance, but also have the obvious disadvantage of large energy consumption. The second category is the electromechanical punching machine, which is a crank punching machine with the crankshaft connecting rod as the conversion device. The reduct...
