Description

Technical Field

[0001] The present application relates to the technical field of sheet metal processing equipment, and in particular to a sheet metal part punching and positioning device. Background Art

[0002] Sheet metal is a type of hardware that is widely used in various fields, such as the automotive field. During the processing, it needs to go through multiple steps before it can finally form the corresponding product, such as stamping and punching.

[0003] In some sheet metal products, corresponding through holes need to be formed on the sheet metal parts. However, the sheet metal parts after stamping have a certain shape, and the through holes formed by stamping are sometimes not in the same direction. When encountering this type of sheet metal parts, the traditional processing method is to use multiple wedge-shaped structures on the punching die to form an oblique punching. This will make the mold design more difficult, the mold structure more complex, and the mold production cost higher. Utility Model Content

In this solution, the rotary drive component can drive the positioning component to rotate, that is, it can convert the position to be punched into vertical punching through rotation. In this way, the punching die only needs to consider vertical movement in design, without considering the coordination of multiple wedge blocks in the case of inclined punching, which effectively reduces the design difficulty of the punching die and reduces production costs.

[0017] Preferably, the rotation drive assembly includes a drive cylinder, an articulated frame and a fixed block;

[0018] The fixing block is connected to the connecting rod and one end thereof away from the connecting rod is rotatably connected to the articulated frame, and the articulated frame is provided at the driving end of the driving cylinder;

[0019] The driving cylinder is suitable for driving the connecting rod to rotate through the articulated frame fixing block;

[0036] In some sheet metal products, it is necessary to form corresponding through holes on the sheet metal. However, the sheet metal after stamping has a certain shape, and the through holes formed by stamping are sometimes not in the same direction. Figure 1 As shown, when encountering this type of sheet metal part, the traditional processing method is to use multiple wedge-shaped structures on the punching die to form an oblique punching, which makes the die design more difficult, the die structure more complex, and the die production cost higher. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0037] For details, see Figure 2-4The present embodiment provides a sheet metal punching and positioning device, comprising a base 10, a stand 11 provided on the base 10, a limit seat 20 provided on the stand 11, and a positioning assembly rotatably provided on the limit seat 20;

[0040] In the above scheme, the positioning device provided in this scheme is used to cooperate with the punching die to complete punching. The design of the stand 11 allows for a certain space to be provided for the assembly of the die. The sheet metal to be processed is assembled on the positioning component to achieve positioning and fixation. After fixation is completed, it cooperates with the punching die to perform punching. In this scheme, the rotary drive component 40 can drive the positioning component to rotate, that is, it can convert the position to be punched into vertical punching through rotation. In this way, the punching die only needs to consider the vertical movement in design, without considering the cooperation of multiple wedge blocks in the case of inclined punching, which effectively reduces the design difficulty of the punching die and reduces production costs.

[0043] In the above scheme, the turntable 31 can be understood as a design similar to a semi-circular disk, in which the arc surface is used to slide with the arc groove of the limit seat 20, so that the turntable 31 can rotate on the limit seat 20; and the protrusion 311 set on the upper end face of the turntable 31 is adapted to the shape of the sheet metal, thereby playing a positioning role; the connecting rod 32 is used to connect the two turntables 31 and is simultaneously connected to the rotation drive assembly 40. The rotation drive assembly 40 drives the connecting rod 32 to rotate to cooperate with the turntable 31 to achieve the plate surface angle adjustment of the sheet metal, which is convenient for subsequent punching.

[0046] Specifically, a limited position through slot 312 is formed on the turntable 31 around its rotation trajectory;

[0047] Furthermore, a limiting column 211 is provided on at least one limiting plate 21, and the limiting column 211 is passed through the limiting slot 312;

[0048] In the above solution, the limiting column 211 cooperates with the limiting groove 312 on the turntable 31 to further limit the turntable 31 without affecting its normal rotation, thereby ensuring the stability of the rotation process of the turntable 31 and the accuracy of subsequent punching.

[0049] Specifically, the rotation drive assembly 40 includes a drive cylinder 41, an articulated frame 42 and a fixed block 43;

[0050] Furthermore, the fixing block 43 is connected to the connecting rod 32 and one end thereof away from the connecting rod 32 is rotatably connected to the articulated frame 42 , which is provided at the driving end of the driving cylinder 41 ;

[0051] Specifically, the driving cylinder 41 is adapted to drive the connecting rod 32 to rotate via the articulated frame 42 and the fixed block 43;

[0052] In the above solution, the driving direction of the driving cylinder 41 is linear, and it can convert the linear motion into the rotational motion of the connecting rod 32 through the articulated frame 42 and the fixed block 43, thereby driving the sheet metal part to rotate.

[0053] Specifically, a plurality of limiting bosses 321 are provided on the connecting rod 32;

[0054] In the above solution, the limiting boss 321 on the connecting rod 32 can play a role in limiting and positioning the sheet metal part, thereby better achieving stable fixation of the sheet metal part.
