Abstract
The invention relates to a processing die and a manufacturing method for a CuCr10 shielding cylinder. The processing die is characterized in that an extrusion die consists of a die cavity (1) and a male die (2). The method for manufacturing the CuCr10 shielding cylinder comprises the following steps: casting a CuCr10 round rod; cutting the CuCr10 round rod into required short materials; continuing to place the short materials in a cold extrusion die cavity; and applying pressure to a blank by using the fixed male die on a press to extrude a cup-shaped shielding cylinder. The method has the advantages of high production efficiency and raw material conservation. The extruded shielding cylinder product has the advantages of precise dimensions and smooth surface.
Description
Technical field
The present invention relates to a kind of preparation method of shielding cylinder, specifically, is processing mold of CuCr10 shielding cylinder and preparation method thereof.
Background technology
Shielding cylinder is used for vacuum interrupter, mainly plays shielding action, reduces the influence of external magnetic field, and electric arc can not burnt partially, to improve the reliability and stability of vacuum interrupter.CuCr10 has not only widened the selection of shielding cylinder use material as the shielding cylinder material, more can improve the even distribution of vacuum interrupter builtin voltage, compares other material shielding cylinder, has more good performance.
The shielding cylinder processing method of prior art all adopts turning or hot extrusion to finish.Turning processing is by the rotation of frock holding workpiece, comes cutting forming with cutter, not only cause the waste of great deal of raw materials, and labour intensity is big, and production efficiency is low; Hot extrusion technique is to more than the recrystallization temperature with blank heating, again the metal of heating is put into mold cavity, under powerful pressure and certain velocity function, force metal to produce violent plastic deformation, thereby obtain the workpiece of required form, this technological operation complexity, and the oxidation that can produce material in operating process have improved production cost.
Summary of the invention
Purpose of the present invention is at the deficiencies in the prior art, provides a kind of and saves time, the processing method of material saving, the CuCr10 shielding cylinder of enhancing productivity.
The present invention mainly finishes by cold extrusion die, and this extrusion die is made of die cavity and punch, and the convex mould diameter size is less than the die cavity diameter dimension.
The present invention mainly finishes by following step;
A. founding goes out the CuCr10 round bar;
B. above-mentioned CuCr10 round bar is cut into short material;
C. with the weak point material blank of above-mentioned CuCr10, be placed in the cold extrusion die cavity, exert pressure by the blank of punch in die cavity fixing on the forcing press.
D. shielding cylinder is taken out in the demoulding.
Owing to leave certain space between die cavity and the punch, make the flow direction of metal blank opposite, thereby be squeezed into cup-shaped shielding cylinder product with the direction of motion of punch.The shielding cylinder that the present invention has the production efficiency height, saves material, pushes, size is accurate, any surface finish.
Description of drawings
Fig. 1 is a mould structure schematic diagram of the present invention
Among the figure: the 1-die cavity; The 2-punch.
The specific embodiment
Below in conjunction with embodiment of accompanying drawing narration, the present invention is described in detail;
A. founding goes out the CuCr10 pole, and the straight warp of pole is 74mm;
B. with above-mentioned CuCr10, be cut into the short material of 25mm;
C. above-mentioned short material is placed in the cold extrusion die cavity 1, exerts pressure to short material blank by punch 2 fixing on the forcing press.The die cavity diameter dimension is 75mm, and convex mould diameter is of a size of 69mm.
D. shielding cylinder is taken out in the demoulding.
Claims (2)
1.CuCr10 the processing mold of shielding cylinder is characterized in that: extrusion die is made of die cavity (1) and punch (2), and the diameter dimension of punch (2) is less than the diameter dimension of die cavity (1).
2. according to the preparation method of the described CuCr10 shielding cylinder of claim 1, it is characterized in that, carry out according to following step:
A. founding goes out the CuCr10 round bar;
B. above-mentioned CuCr10 round bar is intercepted into a plurality of short material;
C is placed on above-mentioned short material in the cold extrusion die cavity, carries out cold extrusion;
D. shielding cylinder is taken out in the demoulding.
