Double acting forging module

Abstract

The invention discloses a double acting forging module. The double acting forging module comprises an upper mold base, an upper punch, a lower mold base, a lower punch and a transmission mechanism, wherein the upper mold base has a through hole; the upper punch is arranged in the through hole of the upper mold base; the lower mold base is arranged corresponding to the upper mold base, and is provided with a through hole corresponding to the upper punch; the lower punch is arranged in the through hole of the lower mold base; when the upper mold base applies downward acting force on the lower mold base, the lower mold base downwards moves; the transmission mechanism comprises a stress slide block arranged below the lower slide base and used for converting the downward acting force to first transverse acting force, a force transfer slide block arranged at one side of the stress slide block and used for converting the first transverse acting force to upward acting force, and a punch slide block arranged above the force transfer slide block and used for converting the upward acting force to second transverse acting force, wherein when the second transverse acting force upwards pushes the upper punch, the upper punch moves to the lower mold base. The double acting forging module can control the relative speed between the upper mold base and the upper punch and the relative speed between the lower punch and the upper punch.

Description

technical field [0001] The present invention relates to a compound forging module, in particular to a method for controlling the upper die base and the upper The relative speed between the punches, and the relative speed between the lower punch and the upper punch are the multiple motion forging modules. Background technique [0002] Most of the traditional forging methods are applied to forging solid forgings (Solid Forgings). Only bifurcated parts, seamless integral pipe fittings and various high-pressure pipe fittings have the characteristics of unidirectional or multi-directional hollow holes. If they are formed by traditional forging The method of forging, multi-pass forging process is necessary, if the heating required before forging and the machining procedures such as shearing edge and drilling required after forging are added, the process required for the entire workpiece may be There are as many as ten passes, and it takes a lot of processing time and causes waste...

Problems solved by technology

[0005] However, if you want to change the relative speed between the lower punch and the upper punch, you usually need to replace another compound forging module to change the relative speed between the lower punch and the upper punch. Change the relative speed among the lateral punch, lower punch and upper punch only by changing the ejector rod or the lateral punch

Furthermore, the lever transmission method of the push rod is to transmit power in the form of a lever, which causes the moving speed of the lower punch to be a variable speed instead of a constant speed, so it is difficult to control the moving speed of the lower punch
