Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blanking dies, and particularly relates to a radial positioning structure of a blanking die insert. Background Art
[0002] A blanking die is a die that punches materials into a specific shape. An insert is a part that directly performs the blanking work and can provide a cutting edge, which is the most important part of a blanking die. In the design of a blanking die, the use of inserts is to meet different blanking requirements, especially for handling complex shapes or parts of the die that need to be frequently replaced.
[0003] During blanking, the insert is subjected to large forces, including the radial thrust in the horizontal direction of the die. Therefore, a backrest is usually set to ensure the stability and accuracy of the blanking process. The design of the backrest helps to control the positioning of the insert, prevent its radial movement or deviation during blanking, which may damage the accuracy of the blanked part, and can also help to disperse the forces generated during blanking, protect the insert from damage, and extend the service life of the die. However, the traditional insert backrest is integrated on the die base body and directly abuts against the outside of the insert, which will increase the width dimension of the die and occupy a large space, making it difficult to use when the space is insufficient. Content of the Utility Model
[0004] In view of this, the utility model provides a radial positioning structure of a blanking die insert, aiming to solve the technical defect that it is difficult to use the insert backrest when the space is insufficient.
[0005] To achieve the above purpose, the technical solution of the utility model is as follows:
[0006] A radial positioning structure of a blanking die insert, characterized in that: it includes a die base and a blanking insert locked on the die base by a threaded fastener. The die base is provided with an upward convex backrest support block. One side of the blanking insert is provided with a cutting edge along the upper edge, and the other side is provided with an avoidance groove. The backrest support block is located in the avoidance groove, and one side side wall of the backrest support block abuts against the bottom of the avoidance groove.
[0007] With the above structure, an avoidance groove is arranged on the back of the blanking insert, and the back support block directly abuts in the groove, saving space. The insert backrest can also be used when the space is insufficient, preventing the radial movement and deviation of the blanking insert during the blanking process.
[0008] Preferably: the backrest support block is integrally formed with the die base. With the above structure, space is saved, the backrest support block has high strength and stable structure.
[0009] Preferably: the avoidance groove is located at the middle position on the back of the blanking insert. With the above structure, the blanking strength of the blanking insert is ensured, and the force balance is ensured.
[0010] Preferably, the back surface of the blanking insert includes an inclined surface and a vertical surface. The inclined surface is the working surface. The avoidance groove penetrates through the inclined surface and the vertical surface along the vertical direction of the blanking insert. The height of the backrest support block does not exceed the height of the vertical surface. With the above structure, it is convenient for installation and ensures that the backrest support block does not affect the normal operation of the blanking insert.
[0011] Preferably, the backrest support block is embedded in the avoidance groove. With the above structure, it does not increase the use of extra space, and the stability of the blanking insert can be ensured even in the case of insufficient space.
[0012] Preferably, there is a gap between both ends of the backrest support block and both ends of the avoidance groove, and the gap is used to adjust the position of the blanking insert. With the above structure, it avoids affecting the circumferential position adjustment of the blanking insert.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] By adopting the radial positioning structure of the blanking die insert provided by the present utility model, an avoidance groove is opened on the back surface of the blanking insert, and the backrest support block can be directly arranged in the avoidance groove to radially position the blanking insert. The opening position of the avoidance groove is small and located in the middle of the back surface of the blanking insert, which reduces the occupied space while ensuring the strength of the blanking insert.

[0019] Figure 5 is a schematic diagram showing the gap 3. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The present utility model will be further described below in conjunction with the embodiments and the drawings.
[0021] As Figure 1 shown, a radial positioning structure of a blanking die insert includes a die base 2 and a plurality of blanking inserts 1. Each blanking insert 1 is fixedly installed on the die base 2 by bolts, as Figure 2As shown in the figure, a backrest support block 21 protruding upward is provided on the die base 2. The backrest support block 21 is integrally formed with the die base 2. A cutting edge 12 is provided along the upper edge of the blanking insert 1, and an avoidance groove 11 is provided on the outside. The backrest support block 21 is located in the avoidance groove 11, and the side wall of the backrest support block 21 abuts against the bottom 111 of the avoidance groove 11. The opening position of the avoidance groove 11 is relatively small, and the influence on the strength of the blanking insert 1 is also relatively small. The backrest support block 21 can provide radial positioning for the blanking insert 1 to prevent the blanking insert 1 from moving or shifting radially during the blanking process.
[0022] As Figure 3 shown, the back surface of the blanking insert 1 includes an inclined surface 13 and a vertical surface 14. The inclined surface 13 is the working surface. In this embodiment, the avoidance groove 11 is rectangular, penetrating the inclined surface 13 and the vertical surface 14, and a fillet is provided at the bottom side. Similarly, as Figure 4 shown, the backrest support block 21 is also rectangular, and a chamfer is provided on the side in contact with the avoidance groove 11. When the blanking insert 1 collides with the side surface of the backrest support block 21, damage can be avoided. As Figure 2 shown, to prevent affecting the normal operation of the blanking insert 1, the backrest support block 21 is embedded in the avoidance groove 11, and its height does not exceed the height of the vertical surface 14.
[0023] As Figure 5 shown, the avoidance groove 11 is located at the middle position of the back surface of the blanking insert 1. There is a gap 3 between both ends of the backrest support block 21 and both ends of the avoidance groove 11. To ensure the required precision for blanking, the position of the blanking insert 1 can be adjusted slightly to avoid this radial reinforcement structure affecting the installation of the blanking insert 1. At the same time, to save space as much as possible and ensure the support strength, as Figure 5 can be seen, in this embodiment, the backrest support block 21 is flush with the vertical surface 13 of the blanking insert 1, which can meet various situations with insufficient space.
[0024] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
