Abstract
The utility model provides a guide cylinder curved surface/center hole extrusion molding method. The die is composed of a upper die plate, an upper die cavity, a lower die plate and a lower die cavity, wherein a male die and a male die mandrel are arranged in the upper die cavity; and an upper female die, a lower female die and a lower made die are arranged in the lower die cavity. The guide cylinder is in a T shape, and the extrusion blank is in a cake shape. In the whole extrusion process, combined extrusion is performed before backward extrusion, thereby solving the problem of cracking in the guide cylinder extrusion process, and greatly lowering the blank cost. The male die mandrel is a staircase type, so that the center hole of the extrusion piece is provided with a rabbet, thereby solving the problem of bulging of the bottom plate of the curve surface after subsequent spline extrusion. A nano micro coating coated on the male die surface can effectively prevent the built-up edges from generation, so that the guide cylinder curve surface has favorable surface roughness.
Description
Technical field
The utility model relates to automobile starter field, specially refers to for pushing the guide cylinder curved surface of one way device for ignitor and the mould of mesopore.
Background technology
Guide cylinder curved surface at present used and mesopore extruding are general with the extrusion modling of T shape blank, and mesopore is straight hole.Guide cylinder curved surface and the mesopore of the extrusion modling of T shape blank, general cost is very high; Mesopore is straight hole, causes after follow-up extruding spline, and curved surface baseplane projection, causes product quality problem.Therefore continue to provide a kind of novel guide cylinder curved surface and middle hole forming equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of employing pie blank to replace T shape blank, and can be by the device of the guide cylinder curved surface of pie blank and mesopore extrusion modling.
For achieving the above object, the technical solution of the utility model is:
Guide cylinder curved surface and mesopore extrusion forming device, comprise cope match-plate pattern, upper cavity, lower bolster, lower mode cavity, wherein on cope match-plate pattern, there is upper cavity, on lower bolster, there is lower mode cavity, it is characterized in that: in upper cavity, have punch, punch end connects punch mandrel, has upper cavity die, lower cavity die, lower punch in lower mode cavity, in the mesopore of lower cavity die, there is lower punch, above lower cavity die, have upper cavity die.
Lower cavity die and upper cavity die are located the axiality that guarantees mesopore by seam.
Punch mandrel is step.
Convex mould surface is received micro-coating.
Good effect of the present utility model is:
1, this practicality adopts pie blank cost can reduce by 30%;
2, the convex mould surface of this device has been done and has been received micro-coating, can effectively prevent the generation of built-up edge, makes guide cylinder curved surface roughness fine;
3, in lower mode cavity, there is lower punch, limited material and flowed downward, effectively prevented part issuable crackle in curved surface and mesopore forming process;
4, punch mandrel is step, so guide cylinder extrusion mesopore has seam, has solved the problem of follow-up extruding spline rear curved surface baseplane projection.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing 1 explanation specific embodiment of the present utility model.
Referring to Fig. 1, pie blank material is put in upper cavity die 7, cope match-plate pattern 1 starts to move downward, thereby drive punch 5 and punch mandrel 6 to start to push pie blank material upwards, lower both direction flows, punch mandrel 6 is step, so guide cylinder extrusion mesopore has seam, solved the problem of follow-up extruding spline rear curved surface baseplane projection, when pie blank material touches lower punch 9, pie blank material stops flowing downward, in lower mode cavity 4, there is lower punch 9, having limited material flows downward, effectively prevented part issuable crackle in curved surface and mesopore forming process, continue extruding, pie blank material all upwards flows, an extrusion process is complete, cope match-plate pattern 1 starts backhaul, take out part, whole operating process is complete.
Extruding overall process is first Compound Extrusion, rear backward extrusion.The utility model has solved the problem that guide cylinder extruding cracks, and greatly reduces the cost of blank simultaneously, and the middle pore area seam of extrusion has simultaneously solved the problem of follow-up extruding spline rear curved surface baseplane projection.
