Abstract
The utility model relates to a steel mould positioning pin which is in a column shape. One end of the column-shaped positioning pin is provided with a chamfer, and the other end of the column-shaped positioning pin is not provided with the chamfer; the middle of the positioning pin is provided with a step; and the width of the step is 3-5 mm. The steel mould positioning pin disclosed by the utility model has the advantages of simple structure, reasonability in design, good positioning, good steel mould concentricity and long service life, cannot generate dislocation due to the action of the step during mould closing, overcomes the defect that the positioning pin is easy to fracture from one end during positioning and saves the mould closing time.
Description
Technical field
The utility model relates to a kind of punching block, especially relates to a kind of punching block alignment pin.
Background technology
The effect of alignment pin is exactly the freely-movable degree of restricted articles, in the mould that is made of two parts or more parts, the adjacent two parts of mould is accurately located and the pin of design; It can be divided into: fixed alignment pin, interchangeable alignment pin, conical surface alignment pin, chamfered edge alignment pin and standard rhombus alignment pin.
Existing punching block alignment pin generally is to be provided with step in the termination of pin, has that end of step to be welded on the counterdie of pile tube punching block, and the workman is when matched moulds, if the upper and lower mould screw hole has deviation slightly, at this moment, dowel hole also deviation can occur, tends to cause the fracture of alignment pin step commissure, cause alignment pin to come off, make troubles to matched moulds, behind the matched moulds, also can cause the dislocation of punching block flange face and running wheel side, cause the punching block concentricity bad, influence the service life of punching block.
The utility model content
Have deficiency in the present technology in order to overcome, the utility model provides a kind of punching block alignment pin.
A kind of punching block alignment pin, described alignment pin is cylindricality, and an end of described cylindricality alignment pin has chamfering, and the other end does not have chamfering, and the middle part of described alignment pin is provided with step.
Preferably, the width of described step is 3～5mm.
Preferably, the length of described step is long than the width of alignment pin.
Preferably, the length of described step is 23～25mm, and the width of described alignment pin is 20～22mm.
Preferably, the angle between described step and the alignment pin is 50～90 °.
Preferably, the angle of described chamfering is 40～60 °.
The utility model is simple in structure, reasonable in design, and polarization is good, and the effect owing to step during matched moulds can not misplace punching block good concentricity, long service life; Alignment pin has been saved the matched moulds time easily from the shortcoming of end fracture when having avoided the location.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of punching block alignment pin, described alignment pin 1 is cylindricality, and an end of described cylindricality alignment pin has chamfering 3, and the other end does not have chamfering, and the angle of described chamfering 3 is 45 °; It is 4mm step 2 that the middle part of described alignment pin 1 is provided with width.
The length of described step 2 is 21.6mm, and the width of described alignment pin 1 is 24mm.Angle between described step 2 and the alignment pin 1 is 60 °.
Described alignment pin forms with No. 45 steel Vehicle Processings, during use, offers a step groove that matches with step at the punching block patrix, and step just is pressed between the upper and lower mould when making matched moulds, and alignment pin does not have an end of chamfering to be welded on the counterdie.This alignment pin uses on punching block, and when not worrying matched moulds, alignment pin is from the problem of end fracture, and matched moulds saves time, and polarization is good.
