Abstract
Aims at overcoming the defect of the prior art, the utility model provides a die for processing a spheroidal end socket, wherein the die has the advantages of simple structure and strong processing stability. The die for processing the spheroidal end socket comprises an upper die and a lower die, wherein a clamping ring is arranged on the upper die.
Description
Technical field
The utility model relates to Machining Technology field, is specifically related to a kind of simple in structure, mould for spherical shell cover processing of strengthening processing stability.
Background technology
Before making mould, spherical shell cover is made by partition machining, partition machining is longevity of service not only, complex steps, most importantly weld seam is many, generally at least needs four weld seams to add a circumferential weld, so not only expends wlding, and the increase of weld seam also increased workload and occurred the probability of cracking, in the manufacturing process of pressure vessel particularly core with weld seam in the making of end socket avoid and minimizing is very important.
Summary of the invention
The purpose of this utility model is the defect for prior art, and a kind of simple in structure, mould for spherical shell cover processing of strengthening processing stability is provided.
The scheme that the utility model solves prior art problem is: a kind of mould for spherical shell cover processing comprises upper die and lower die, and wherein patrix is provided with blank holder.
Preferably, patrix is provided with blank holder, in drawing process, wrinkling for preventing workpiece peristoma part unstability.
Compared with prior art, the utility model the utility model by arranging a blank holder on original processing die holder, frictional force that in punching course, sheet material is subject to is increased, increase the sheet material required dynamics that glides, improve stability and the yield rate of sheet material processing; And there is simple in structure, easy to operate feature, suitable promoting the use of.
Accompanying drawing explanation
Fig. 1 is upper die structure schematic diagram of the present utility model;
In figure: 1, blank holder.
Fig. 2 is lower die structure schematic diagram of the present utility model;
Fig. 3 is patrix top view of the present utility model.
The specific embodiment
Below in conjunction with embodiment, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As figure,
The scheme that the utility model solves prior art problem is: a kind of mould for spherical shell cover processing comprises upper die and lower die, and wherein patrix is provided with blank holder.
Preferably, patrix is provided with blank holder, in drawing process, wrinkling for preventing workpiece peristoma part unstability.
Compared with prior art, the utility model the utility model by arranging a blank holder on original processing die holder, frictional force that in punching course, sheet material is subject to is increased, increase the sheet material required dynamics that glides, improve stability and the yield rate of sheet material processing; And there is simple in structure, easy to operate feature, suitable promoting the use of.
Operation principle of the present utility model is: bed die is fixed, and by the punching press of patrix, carries out the processing to end socket.
The technology that the utility model does not relate to all can be realized by prior art.
Claims (2)
1. for a mould for spherical shell cover processing, comprise upper die and lower die, it is characterized in that: patrix is provided with blank holder.
2. the mould for spherical shell cover processing as claimed in claim 1, is characterized in that: counterdie is fixed, and patrix is semi-spherical shape.
