Cold forging machine capable of forging two ends

Abstract

The invention relates to a cold forging machine capable of forging two ends, which mainly solves the problem that the existing cold forging machine cannot realize the technology of completing the even upsetting of both ends of a blank at one time. The cold forging machine capable of forging two ends comprises a rack, a material delivering mechanism, an upset head mould, a first stamping mechanism and a drive mechanism, wherein a feed hole for allowing the blank to extend into is arranged on the rack, the material delivering mechanism consists of a first pushing mechanism and a second pushing mechanism, the cold forging machine capable of forging two ends further comprises a mould core and a second stamping mechanism, the mould core consists of a left half mould core and a right half mould core and is used for clamping the blank, a linear reciprocating movable end of the first pushing mechanism is fixedly connected with the left half mould core, the linear reciprocating movable end of the second pushing mechanism is fixedly connected with the right half mould core, and the second stamping mechanism is used for driving a lower mould to do linearly reciprocating movement; and the first stamping mechanism and the second stamping mechanism are matched and simultaneously form first top press fit with both the end parts of the blank, and the second stamping mechanism is also used for forming the second top press of the lower mould and the blank, so that the blank is separated from the lower mould.

Description

technical field

[0001] The invention relates to a cold pier machine, in particular to a cold pier machine capable of piercing two ends. Background technique

[0002] In the processing technology of the ring rigging, it is necessary to pierce the two ends of the cylindrical blank so that the diameter of the two ends is slightly larger than the diameter of the middle part. In order to achieve this purpose, first use the cold pier machine to process the blank into a blank with only one end thick, and then use a punch to thicken the other end of the blank. This processing technique is complicated and the production cost is high.

[0003] The cold pier machine on the market comprises frame, driving mechanism, mould, feeding mechanism, cutting material mechanism, material shifting mechanism, punching die mechanism. Among them, the driving mechanism is mainly composed of a motor, a reduction mechanism, and a crankshaft. The die mechanism is mainly composed of connecting rods and...
