Abstract
A punch for punching 504 holes of a housing of a Chang'an Mazda exhaust system comprises a working part (1) and a fixed part (2). A supporting part is arranged between the working part (1) and the fixed part. The punch is characterized in that the supporting part is composed of a transition supporting part (3) and an enhanced supporting part (4), the diameter of the enhanced supporting part (4) is larger than that of the transition supporting part (3), and the transition supporting part (3) is larger than the working part (1) in diameter. By means of reasonable distribution of the diameter of the supporting part, the overall strength is greatly enhanced, the strength of the punch can meet the requirement for punching force, and normal production of dies is guaranteed.
Description
Technical field
The utility model relates to a kind of specific purpose tool, especially a kind of punching special punch, specifically Mazda, a kind of Chang'an gas extraction system case 504 hole punching drifts.
Background technology
Upper intensive 504 holes that are provided with of Mazda, Chang'an gas extraction system case (as Fig. 1), because quantity can not machine by boring milling greatly, therefore, conventional way is to adopt punch process, existing punch structure as shown in Figure 2, because drift quantity is many, support section length is large, size is little, therefore the phenomenon that often occurs in process of production drift fracture, causes that product is defective even to be scrapped, and therefore must be improved.
Summary of the invention
The purpose of this utility model be for existing special punch due to unreasonable structure, easily, in the problem of punching course Fracture, design a kind of Mazda, Chang'an gas extraction system case 504 hole punching drifts that can increase drift bulk strength.
The technical solution of the utility model is:
Mazda, a kind of Chang'an gas extraction system case 504 hole punching drifts, it comprises working portion 1 and standing part 2, between working portion 1 and standing part, be provided with support section, it is characterized in that described support section by transition support section 3 and strengthen support section 4 forming, and the diameter that strengthens support section 4 is greater than the diameter of transition support section 3, and transition support section 3 is greater than the diameter of working portion 1.
The length of described enhancing support section 4 is greater than the length of transition support section 3.
The beneficial effects of the utility model:
The utility model by the diameter dimension of reasonable distribution support section, has increased bulk strength greatly, makes the intensity of drift can meet the needs of blanking pressure, guarantees the normal production of mould.
The utility model is simple in structure, easily manufactured.
Accompanying drawing explanation
Fig. 1 is the applicable product parts schematic diagram of the utility model drift.
Fig. 2 is the structural representation of existing drift.
Fig. 3 is the structural representation of drift of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 3.
Mazda, a kind of Chang'an gas extraction system case 504 hole punching drifts, it comprises working portion 1 and standing part 2, between working portion 1 and standing part, be provided with transition support section 3 and strengthen support section 4, and the diameter that strengthens support section 4 is greater than the diameter of transition support section 3, transition support section 3 is greater than the diameter of working portion 1, wherein the diameter of working portion 1 is 3 millimeters, he wants 10 millimeters, transition support section be directly 5 millimeters, length is 18.5 millimeters, the diameter that increases part is 6 millimeters, he wants 25 millimeters, the length of standing part is 5 millimeters, diameter is determined by drift retained part, generally should be greater than the diameter that increases part.As shown in Figure 3.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
Claims (2)
1. Mazda, Chang'an gas extraction system case 504 hole punching drifts, it comprises working portion (1) and standing part (2), between working portion (1) and standing part, be provided with support section, it is characterized in that described support section by transition support section (3) and strengthen support section (4) forming, and the diameter that strengthens support section (4) is greater than the diameter of transition support section (3), and transition support section (3) is greater than the diameter of working portion (1).
2. drift according to claim 1, is characterized in that the length of described enhancing support section (4) is greater than the length of transition support section (3).
