A clamping die upsetting machine and its working method

Abstract

Provided is a clamp die upsetting machine, comprising a machine body (1), a punching die assembly (3), a punching die assembly drive mechanism, a feed mechanism, and a cropping cover (37); a clamp die assembly (39) is disposed on the machine body; the clamp die assembly (39) comprises a first clamp die base (55) and a second clamp die base (56); a first mounting space (57) is disposed at the side face, adjacent to the second clamp die base (56), of the first clamp die base (55); a second mounting space (58) is disposed at the side face, adjacent to the first clamp die base (55), of the second clamp die base (56); also disposed are a first clamp die drive mechanism for driving the first clamp die (55) in translational motion, and a second clamp die drive mechanism for driving the second clamp die (56) in translational motion; the working method is: the translational motion of the clamp die assembly is used to achieve displacement whole-circle cropping and workstation-piece material delivery; then, upsetting is performed; thus the needs for a separate cropping mechanism and material clamping and blank delivery mechanism are eliminated, and the functions of clamp die cropping, clamp die upsetting, and clamping are achieved.

Description

Technical field [0001] The invention relates to an upsetting machine and its working method. Background technique [0002] The upsetting machine is a device that uses the back and forth movement of a large slider to upset the blank in the main die through a punch. [0003] The upsetting machine is mainly composed of a machine body, a punch assembly, a punch assembly drive mechanism, a main die, an ejection mechanism, a feeding mechanism and a cutting mechanism. [0004] In the traditional upsetting machine, the punch assembly and the die included in the main die are fixed on the corresponding body. The upsetting machine with this structure has many mechanical mechanisms, complex structures, many failures, difficult operations, and low upsetting efficiency. , Feeding and discharging are both troublesome. [0005] At present, the one-die two-punch forging machine and the multi-die and multi-punch forging machine that realize the shift between the forging stations through the lifting mo...

Problems solved by technology

These two types of upsetting machines mostly use wire rods as raw materials for upsetting at present. Therefore, before upsetting, the wire rods must be cut into blanks according to the size requirements of the formed parts. In order to realize this process, upsetting machines need separate The installation of material cutting device and material clamping and conveying device makes the structure of the whole heading machine complex, and requires high cooperation among cutting material, upsetting and ejection, and it is difficult to realize high-speed upsetting, and debugging is particularly troublesome

[0006] For the multi-mode and multi-blow upsetting machine, the dies are arranged horizontally, the multiple dies are fixed, and the multiple punches only move in one direction for the upsetting section. Since the dies or punches will not move in translation, therefore, The billet can only be transferred by clamp movement, and the billet is only upset once in the die

[0007] In addition, for the existing upsetting machine, the die is basically an integral structure, and for the formed die, the cavity is determined. Therefore, on the premise of not changing the die, basically only one kind of molding can be formed. Upsetting parts, at the same time, it is also impossible to upsetting complex shaped parts
