Description
Technical Field
The utility model belongs to the technical field of the stamping die technique and specifically relates to a high strength buoyancy lift uide pin.
Background
Conventional lift guide pins generally take two forms: a lift guide pin for a sheet (fig. 1); the other is a lift guide pin for thick plates (fig. 2). However, both of the two methods have defects, and in any method, the head of the stamping die is broken in the production process, so that the stamping die is stopped, even the broken head falls into a die cavity, the die is exploded, and meanwhile, the stamping die has potential safety hazards that the stamping die flies out of the die and injures people.
Disclosure of Invention
The utility model discloses an overcome prior art not enough, provide a high strength buoyancy lift uide pin, change the structure of buoyancy lift uide pin, the design of buoyancy lift uide pin head is consolidated and is strengthened, difficult rupture, intensity is high.
In order to realize above-mentioned purpose, design a high strength buoyancy lift uide pin, including the uide pin body, its characterized in that: an anti-rotation surface is arranged on one side of the guide pin body, a guide groove is arranged on the guide pin body on the back of the anti-rotation surface, and the guide groove is positioned at the upper part of the guide pin body; the outer edge of the top of the guide pin body is provided with an inclined plane; the connecting flange is positioned at the lower part of the guide pin body, and the diameter of the flange is larger than that of the guide pin body; and the spring guide pin is connected to the bottom of the flange, and the center of the spring guide pin is consistent with that of the guide pin body.
The anti-rotation surface is a plane and penetrates through the top of the guide pin body and the bottom of the flange from top to bottom.
And chamfers are respectively arranged at the joints of the two ends of the inclined plane and the guide pin body.
The guide pin body, the flange and the spring guide pin are of an integrated structure.
Compared with the prior art, the utility model, a high strength buoyancy lift uide pin is provided, changes the structure of buoyancy lift uide pin, and buoyancy lift uide pin head design is consolidated and is strengthened, difficult rupture, and intensity is high.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 3 and 4, an anti-rotation surface 1 is arranged on one side of the guide pin body, a guide groove 3 is arranged on the guide pin body on the back of the anti-rotation surface 1, and the guide groove 3 is arranged at the upper position of the guide pin body; the outer edge of the top of the guide pin body is provided with an inclined plane 2; the lower part of the guide pin body is connected with a flange 4, and the diameter of the flange 4 is larger than that of the guide pin body; the spring guide pin 5 is connected to the bottom of the flange 4, and the center of the spring guide pin 5 is consistent with the center of the guide pin body.
The anti-rotation surface 1 is a plane and penetrates through the top of the guide pin body and the bottom of the flange 4 from top to bottom.
Chamfers are respectively arranged at the joints of the two ends of the inclined plane 2 and the guide pin body.
The guide pin body, the flange 4 and the spring guide pin 5 are of an integral structure.
The specific design description is as follows:
1. the side surface of the guide pin body is provided with the anti-rotation surface 1, so that the guide pin body is prevented from rotating or even being stuck when moving up and down in the stamping process.
2. The top surface of the head of the guide pin body is provided with an inclined plane 2, and chamfering processing is carried out on two ends of the inclined plane 2, so that the accident that the head of the pin is broken when the stripper plate of the upper die is contacted at one side is avoided, and the stress is good.
3. The optimized design of the guide groove 3 is not the shape of a circle of tool retracting grooves, only one transverse groove is formed, the effect of guiding the material belt is achieved, the strength of the pin can be greatly improved, analysis is carried out from a mechanical angle, and the fracture resistance of the pin is greatly improved.
4. The thickness of the flange 4 is greater than conventional types, avoiding the occurrence of accidents of breakage of the flange portion.
5. Design spring and lead positive round pin 5, prevent that the round pin is at the in-process of activity from top to bottom, the phenomenon that the spring can take place to warp, the spring damage.
