Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive work, are related to the scope of the present invention.
The nut mould in the prior art is generally only a base body 2 with a forming hole 1, the forming hole 1 is in the shape of the outline of the nut to be punched, the outline of the nut to be punched is an irregular rectangle, any one diagonal is an arc angle 6, the other diagonal is a sharp angle 7, and the side lengths are in parallel with each other. The nut mould of prior art for during the punching press, the section bar is difficult for the fracture in punching press position, in order to solve this technical problem, has proposed following several kinds of nut moulds and has the processingequipment of nut mould, can form the secondary cutting in the punching press process, makes the section bar change in the fracture, and concrete structure is as follows:
example 1
As shown in fig. 1 to fig. 3, this embodiment provides a nut mold based on the prior art, including a base 2 having a forming hole 1, and further including an open slot 3 communicating the forming hole 1 and an outer side of the base 2, a bottom surface of the open slot 3 is lower than a surface of the base 2, a depth of the open slot 3 is 4 to 8mm, which may be 5mm, 6mm or 7mm, a first edge 4 is formed on the forming hole 1 and the surface of the base 2, a second edge 5 is formed on the forming hole 1 and the bottom surface of the open slot 3, and the first edge 4 and the second edge 5 jointly form a closed shape in a projection plane.
Through this kind of structure, first sword limit 4 and second sword limit 5 that are not in the coplanar and from high to bottom are formed, conveniently carry out the secondary hydraulic pressure, specifically: during primary hydraulic pressure, the first edge 4 is matched with the forming cutter 12 to cut off one end of the long-strip-shaped section to be processed, secondary hydraulic pressure is performed, during secondary hydraulic pressure, the second edge 5 located below is matched with the forming cutter 12 to cut off the other end of the long-strip-shaped section to be processed, the shape and contour of the nut are punched, and the formed nut is blanked. The secondary hydraulic stamping mode can ensure that the workpiece is not easy to deform and bend.
Furthermore, the open slot 3 in this embodiment is different from a ring slot, the open slot 3 communicates the outside of the forming hole 1 and the base 2, the opening direction of the open slot 3 is along the feeding direction of the long-strip-shaped section, so that the long-strip-shaped section can be bent toward one side of the open slot 3 by taking the first edge 4 as a base edge when the long-strip-shaped section is subjected to primary hydraulic pressure, secondary hydraulic pressure is performed when one section of the long-strip-shaped section in the forming hole 1 is in an inclined bending state, and after the secondary hydraulic pressure, the outer shape profile of the nut is stamped. The bending can further enhance the cutting effect of the first blade edge 4 and the second blade edge 5, and reduce the loss of the cutter. If the ring groove is synchronously stressed, the bending type cutting effect cannot be realized.
