Abstract
The invention relates to a belt wheel bevel gear die which comprises an upper punch, a middle die body and a lower punch. A tooth die is arranged at the bottom end of the upper punch. An upper inner punch body is arranged in the upper punch. An upper inner punch gland is disposed at the top end of the upper inner punch body. The lower punch is fixed through a lower punch gland. The upper punch and the lower punch extend into an inner cavity of the middle die body. A belt wheel bevel gear punched through the die has the characteristics of being smooth in surface, free of burrs and attractive in appearance. Meanwhile, the die is formed integrally in a punched mode, materials are saved, machining precision is high, and the die is suitable for large-scale production.
Description
Technical field
The present invention relates to a kind of mould, especially relate to a kind of belt wheel umbrella tooth mould.
Background technology
Be the parts be applied on electric tool with bevel gear, the existing band bevel gear mode of production all needs to carry out secondary operations after shaping, to reduce the burr of umbrella tooth surface, and production efficiency west, and the machining accuracy of umbrella tooth is low, accommodation is little, waste raw material.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides the belt wheel umbrella tooth mould that a kind of machining accuracy is high.
In order to overcome the defect existed in background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of belt wheel umbrella tooth mould, comprise upper punch, middle mould and undershoot, upper punch bottom is provided with tooth mould, interior punching is provided with in upper punch, end of rushing to summit in upper is provided with interior stamping cover, and undershoot is fixed by lower stamping cover, and upper punch and undershoot all stretch in middle mold cavity.
The invention has the beneficial effects as follows: the belt wheel umbrella tooth adopting mould punching to go out, has smooth surface, without crude, the feature of good looking appearance; Simultaneously because mould punching is one-body molded, save material, and machining accuracy is high, is applicable in enormous quantities operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
A belt wheel umbrella tooth mould as shown in Figure 1, comprises upper punch 1, middle mould 2 and undershoot 3, and upper punch 1 bottom is provided with tooth mould 4, interior punching 5 is provided with in upper punch 1, in upper, punching 5 tops are provided with interior stamping cover 6, and undershoot 3 is fixed by lower stamping cover 7, and upper punch 1 and undershoot 3 all stretch in middle mould 2 inner chamber.
The belt wheel umbrella tooth adopting mould punching to go out, has smooth surface, without crude, and the feature of good looking appearance; Simultaneously because mould punching is one-body molded, save material, and machining accuracy is high, is applicable in enormous quantities operation.
