A die closing upsetter and a working method

Abstract

The invention provides a die closing upsetter and a working method. The die closing upsetter comprises a machine body, a punch assembly, a punch assembly driving mechanism, a feeding mechanism and a material cutting sleeve; the machine body is provided with a die closing assembly which comprises a first die closing base and a second die closing base; the side surface, close to the second die closing base, of the first die closing base is provided with a first installing groove; the side surface, close to the first die closing base, of the second die closing base is provided with a second installing groove. A first die closing driving mechanism driving the first die closing base to translate and a second die closing driving mechanism driving the second die closing base to translate are also arranged. The working method comprises the steps of feeding materials, realizing displacement full-circle material cutting through the translation of the die closing assembly, and performing upsetting. The working method requires no independent material cutting mechanism and material clamping and blank delivering mechanism, realizes die closing material cutting and die closing upsetting and achieves the effect of a clamp.

Description

technical field [0001] The invention relates to an upset forging machine and its working method. Background technique [0002] The upsetting machine is a device that uses the back and forth movement of the large slider to upset the blank in the main die through the punch. [0003] Upsetting machine is mainly composed of machine body, punch assembly, punch assembly driving mechanism, main mold, ejector mechanism, feeding mechanism and shearing mechanism. [0004] In the traditional upsetting machine, the punch assembly and the die included in the main die are all fixed on the corresponding machine body. The upsetting machine with this structure has many mechanical mechanisms, complex structure, many faults, difficult operation and low upsetting efficiency. , Feeding and discharging are more troublesome. [0005] At present, the one-die two-blow upsetting machine and the multi-die multi-punch upsetting machine are used more frequently to realize the displacement between the ...

AI Technical Summary

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
