Problems solved by technology

In the fastener industry, the shortest trimming specification of a type of cold heading is limited. For example, the shortest trimming length of Kasuga Equipment CBF-204L is 25mm. If it is less than this length, the clamp cannot be transferred, and the trimming process cannot be realized.
Therefore, the scope of use of the equipment is small and cannot meet the needs of the market

Abstract

The invention discloses an edge-cutting processing mould for a cold pier ultra-short rod product. The edge-cutting processing mould comprises a front die body, a back die body, an edge-cutting punch die, an edge-cutting top die, a floating mechanism and ejector rods; the edge-cutting punch die is internally embedded to the back end of the front die body, and the edge-cutting top die and the floating mechanism are arranged in the back die body; the edge-cutting top die is arranged in front of the floating mechanism, ejector rods capable of ejecting punching shaping spare parts from a concave cavity of the edge-cutting top die are penetrated on the edge-cutting top die and the floating mechanism; the floating mechanism comprises a fixing body, a floating body and a spring; the front part of the fixing body is provided with a floating body, and the fixing body is in supporting connection with the floating body through a spring; the front end face of the floating body is bonded to the back end face of the edge-cutting top die. Compared with the prior art, the edge-cutting processing mould can enlarge the using scale of a device, meet the market demand; moreover, the edge-cutting processing mould is simple in structure.

Description

【Technical Field】 [0001] The invention relates to the technical field of a mold, in particular to the technical field of a cold-heading ultra-short rod product trimming processing mold. 【Background technique】 [0002] The cold heading machine is a kind of special equipment that is mainly used for the mass production of nuts and bolts and other fasteners. It is used as a machine for upsetting and forging of metals at room temperature. The cutting and heading can be completed sequentially on the cold heading machine. Processes such as accumulation, forming, chamfering, thread rolling, diameter reduction and trimming. In the fastener industry, the shortest trimming specifications of one type of cold heading are limited. For example, the shortest trimming length of the Kasuga equipment CBF-204L is 25mm. If the length is less than this length, the clamp cannot be transferred and the trimming process cannot be realized. Therefore, the equipment has a small range of use and cannot meet...
