The press working is usually performed by mounting a press die on a press machine. In order to be able to punch and shape sheet metal parts with high strength and hardness, the punch press can exert a large force, such as 50 tons, on the punch die and the sheet metal parts during operation. In order to avoid the damage of the stamping die in the stamping process, other auxiliary elements such as elastic parts and the like are usually required to be arranged on the stamping die to reduce the impact force, so that the number of parts is large, the structure is complex, and a complex program control punch is also required to be arranged; meanwhile, in order to prevent the stamping die from falling off from the punch in the stamping process, the connecting structure between the stamping die and the punch is also complex, so that the stability of the stamping die is ensured. Moreover, when some elements with lower strength and hardness are processed, larger force is not required to be applied, and the risk coefficient in the operation process is higher and the operation process is more complicated due to the adoption of punching machine processing.

In order to solve the above problems, as shown in fig. 1 to 5, the present utility model provides a stamping die which can be used for stamping a wire hole boss on a sheet metal tie seat or processing other elements with lower strength and hardness, and which has a simple structure and is convenient and safe to operate.

As shown in fig. 1 to 2, specifically, a stamping die is used for a squeeze riveter, the squeeze riveter includes a base and a squeeze member, the stamping die includes a first die 1, a second die 2 and a fixing structure 3, wherein: the first die 1 is arranged on the pressing piece, and one end of the first die 1 facing the base is provided with a stamping protrusion 11; the second die 2 is arranged on the base, so that one end of the second die 2 facing the pressing piece is used for placing a sheet metal part and is provided with a stamping groove 21 which can be matched with the stamping protrusion 11, so that when the pressing piece drives the first die 1 to press down, the sheet metal part is stamped and formed through the matching of the stamping protrusion 11 and the stamping groove 21; the fixed knot constructs 3 and sets up in second mould 2, and second mould 2 is fixed with the squeeze riveter through fixed knot constructs 3.

As mentioned above, other auxiliary elements such as an elastic element are usually required to be arranged on the existing stamping die for the punch press to reduce the impact force, so that the structure is complex; moreover, when some elements with lower strength and hardness are processed, larger force is not required to be applied, and the risk coefficient in the operation process is higher and the operation process is more complicated due to the adoption of punching machine processing. The stamping die provided by the embodiment of the utility model is used for the squeeze riveter, a complex program is not required to be arranged in the operation process of the squeeze riveter, and the force applied to the stamping die and the sheet metal part by the squeeze riveter in the working process is small, such as 7 tons, so that the danger coefficient in the stamping process can be reduced; meanwhile, as the force applied by the riveting press on the stamping die is small, the first die 1 and the second die 2 are not easy to damage or fall off from the riveting press in the stamping process, and therefore, a simpler connection mode can be arranged between the first die 1 and the pressing piece and between the second die 2 and the base, wherein the first die 1 can be directly connected with the pressing piece, and the second die 2 is fixed with the base through the fixing structure 3, so that the stability of the second die 2 in the stamping process is ensured, and the stamping die is simple in structure and convenient for a user to install and operate.

Wherein, the one end of second mould 2 towards first mould 1 is equipped with punching press platform 23, and punching press groove 21 is seted up in punching press platform 23, and the sheet metal component can be stably placed on punching press platform 23. The shape of the punching groove 21 and the punching protrusion 11 may be a trapezoid structure as shown in the drawing, or may be changed according to the shape and structure of the sheet metal part actually required to be punched, and is not particularly limited herein.

When the sheet metal part with lower stamping strength and hardness is required to be stamped by using the stamping die, the first die 1 is firstly installed to the pressing part of the riveting press, the second die 2 is installed to the base of the riveting press through the fixing structure 3, then the sheet metal part to be processed is placed on the stamping platform 23, the sheet metal part completely covers the stamping groove 21, and the pressing part of the riveting press drives the first die 1 to synchronously press down when being pressed down, and the stamping protrusion 11 stretches into the stamping groove 21 to stamp and form the sheet metal part.

As shown in fig. 1 to 2, the stamping die further includes a positioning assembly 4, where the positioning assembly 4 includes a first positioning member 41 disposed on the first die 1 and a second positioning member 42 disposed on the second die 2, and when the first die 1 is pressed down, the first positioning member 41 can be matched with the second positioning member 42, so as to align the stamping protrusion 11 with the stamping slot 21. When the first positioning piece 41 and the second positioning piece 42 are matched to ensure that the first die 1 is pressed down, the stamping protrusion 11 can accurately extend into the stamping groove 21, and the phenomenon that sheet metal parts are not stamped and formed or the dimensional accuracy of products is poor due to dislocation of the stamping protrusion 11 and the stamping groove 21 is avoided, so that the qualification rate of the products can be improved.

When the stamping protrusion 11 is dislocated from the stamping groove 21, the positioning protrusion 421 cannot extend into the positioning groove 411, and at this time, the pressing member cannot control the first die 1 to continue pressing, so that the stamping failure of the sheet metal part can be avoided. In other embodiments, the first positioning member 41 and the second positioning member 42 may be configured to be capable of attracting each other, such as a magnet and an iron block, so long as the positioning function can be performed on the first mold 1 and the second mold 2, so long as the punching protrusion 11 can be accurately inserted into the punching groove 21 when the first mold 1 is pressed down, and no specific limitation is imposed herein.
