Description

A kind of flat-die forging major diameter lopps reaming forging apparatus
Technical field
The utility model relates to a kind of flat-die forging major diameter lopps reaming forging apparatus, belongs to technical field of forging.
Background technology
Along with the develop rapidly of China's mechanical field, also more and more higher to the requirement of the mechanical performances such as intensity of part, forge and in industrial production, just seem increasingly important, wherein, flat-die forging is widely used in the manufacturing field as a kind of important forging mode.
Flat-die forging is to utilize impulsive force or pressure to make metal at all directions Free Transform between anvil face up and down, and is unrestricted and obtain a kind of processing method of the forging of required form and size and certain mechanical performance.Flat-die forging used tool and equipment are simple, and versatility is good, and cost is low.Compare with cast blank, open die forging has been eliminated the defectives such as shrinkage cavity and porosity, pore, makes blank have higher mechanical property.The forging simple shape, flexible operation.Therefore, it has the meaning of particular importance in the manufacturing of heavy-duty machine and strength member.But flat-die forging also has its defective clearly, and in the reaming operation when forging the major diameter ring forgings, workman's high labour intensity and lower operating efficiency are exactly one of them.For forging the major diameter ring forgings, be that the workman clamps forging with pliers and gyrates during in the past this forging reaming, workman's labour intensity is very high, production efficiency is lower, and the rotation amplitude of forging all is to grasp by workman's experience, the even situation of forging wall unevenness after easily forging.
The utility model content
When the utility model had the flat-die hammer reaming now for solving, the workman clamped not stall of forging by pliers and moves, and workman's labour intensity is high; The rotation amplitude of forging all is to grasp by workman's experience, for the less workman of experience, and the even situation of forging wall unevenness after easily forging; And the problem that production efficiency is lower provides a kind of flat-die forging major diameter ring forgings reaming forging apparatus.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: a kind of flat-die forging major diameter lopps reaming forging apparatus, the reaming of described a kind of flat-die forging major diameter lopps comprises upper hammer anvil with forging apparatus, lower hammer anvil, saddle, saddle support, the forging hammer bumper, saddle support is horizontally positioned on the lower hammer anvil, the upper middle position in saddle support front has perforation, the little groove of the vest of opening upwards, groove shapes is rectangular, the centre position of saddle support side has perforation, the saddle support big groove of opening upwards, its shape also is rectangle, and the perforation perpendicular direction with the little groove of saddle support, the downside of saddle is the plane, top is circular-arc, the saddle level is placed on the little groove of saddle support, the forging hammer bumper is positioned at the position of taking back in the hammer anvil top, the reaming of described a kind of flat-die forging major diameter lopps also comprises a strip metal chain and a metal tube with forging apparatus, the metallic bond upper end is connected with the forging hammer bumper, the lower end of metallic bond is connected with metal tube, and metal tube is positioned at the saddle support big groove and is positioned at the below of the little groove of saddle support apart from the end points of the nearlyer end of saddle support.
The utility model compared with prior art has following beneficial effect: even with the major diameter ring forgings wall thickness that forging apparatus forges by a kind of flat-die forging major diameter lopps of the present utility model reaming, type quality is good; Simple to operation, labor strength is low, has improved production efficiency, and production efficiency can improve 30%-40%.
