Compared with the rotating mechanism in the related art, the punch pendulum block angle adjustment mechanism shown in the embodiment of the present application has a simple structure and occupies a small space. The above structures are described in detail below in conjunction with the accompanying drawings.

Figure 1 , Figure 2 and Figure 6 The first support 10 may be a support plate, a support frame or other structures having a support function. The punch swing block 20 is hinged to the first support 10 via the first hinge shaft 11, which determines the rotation trajectory of the punch swing block 20, so that the punch swing block 20 can rotate clockwise or counterclockwise around the first hinge shaft 11 relative to the first support 10. For example, refer to Figure 1 , Figure 2 and Figure 7 A bracket 13 may be provided on the first support 10, and the punch pendulum block 20 is rotatably connected to the bracket 13 via the first hinge shaft 11. For example, refer to Figure 2 The bracket 13 can be fixed on the first support 10 by a first screw 14. Figure 1 and Figure 2 The first hinge shaft 11 can be locked in the hinge hole of the bracket 13 and the punch block 20 by the first cotter pin 12. For example, the first support 10 can be fixed to an external support platform, support frame or other supporting structure by the second screw 15. Figure 8 The punch pendulum block 20 is used to connect with a clamping mechanism such as but not limited to, to drive the clamping mechanism to rotate. The clamping mechanism can be used to clamp workpieces such as but not limited to stamping parts.

[0043] When setting the drive component, the drive component can at least be a retractable drive component, that is, the drive component can at least be retractable. The specific implementation of the retractable drive component can be implemented in a variety of ways, that is, the retractable drive component can be implemented in a variety of ways. For example, refer to Figure 1 and Figure 2 , components such as but not limited to the cylinder 30 may be used as components of the drive assembly.

[0044] Exemplary, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 The drive assembly may include a cylinder 30, and the cylinder 30 has a piston rod 31. The cylinder 30 is configured to rotate the punch pendulum block 20 relative to the first support 10 when the piston rod 31 is extended. By using the cylinder 30 as a retractable drive assembly, the structure of the drive assembly can be simplified, the space occupied by the drive assembly can be reduced, and the cost can be reduced. It should be noted that the drive assembly is not limited to the method of using the cylinder 30, and other methods can also be used.

[0045] When setting the cylinder 30, various methods can be used. For example, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 , the cylinder 30 is a telescopic cylinder. Exemplarily, the cylinder 30 can be a standard cylinder 30. Exemplarily, the cylinder 30 has a cylinder body 32 and a piston rod 31, and the piston rod 31 is assembled in the cylinder body 32 and can be extended or shortened. The cylinder 30 is connected to the punch pendulum block 20, and the cylinder 30 is configured so that when the piston rod 31 is extended or retracted, the punch pendulum block 20 can rotate relative to the first support 10. That is, when the piston rod 31 of the cylinder 30 is extended or retracted, it can be determined that the punch pendulum block 20 rotates relative to the first support 10. The configuration of the cylinder 30 can be adopted in a variety of ways, and several settings are introduced as examples below.

[0046] Exemplary, reference Figure 1 , Figure 2 , Figure 3 and Figure 4, the punch pendulum block angle adjustment mechanism may further include: a second support 40. One of the cylinder body 32 and the piston rod 31 of the cylinder 30 is hinged to the second support 40 through the second articulation axis 41, and the other is hinged to the punch pendulum block 20 through the third articulation axis 33. And the first articulation axis 11, the second articulation axis 41 and the third articulation axis 33 are all arranged in parallel. Specifically, the cylinder body 32 of the cylinder 30 may be articulated to the second support 40 through the second articulation axis 41, and the piston rod 31 of the cylinder 30 may be articulated to the punch pendulum block 20 through the third articulation axis 33. In other embodiments, the cylinder body 32 of the cylinder 30 may also be articulated to the punch pendulum block 20 through the third articulation axis 33, and the piston rod 31 of the cylinder 30 may be articulated to the second support 40 through the second articulation axis 41. For example, refer to Figure 1 and Figure 2 The second support 40 can be hinged to the cylinder body 32 of the cylinder 30 through a second hinge shaft 41, and the second hinge shaft 41 is locked in the hinge hole of the second support 40 and the cylinder body 32 through a second cotter pin 42.

[0047] Regarding the configuration of the second support 40, any carrier that can provide support may be used. Figure 1 and Figure 2 The second support 40 may be a support plate, a support frame or other structures having a support function. Figure 1 and Figure 2 , the second support 40 can be fixed to an external support structure such as a support platform or a support frame by a sixth screw 43. The positions of the second support 40 and the first support 10 can be configured in any manner. For example, the second support 40 can be located at the lower right position of the first support 10. The second support 40 is hinged to a structure in the cylinder body 32 or the piston rod 31 of the cylinder 30 through a second hinge shaft 41, and another structure on the cylinder 30 is hinged to the punch pendulum block 20 through a third hinge shaft 33, thereby forming a connecting rod-like mechanism between the punch pendulum block 20 and the cylinder 30. When the piston rod 31 of the cylinder 30 is extended or retracted, the punch pendulum block 20 can be driven to rotate relative to the first support 10.

[0048] Exemplary, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9, the piston rod 31 has a first end and a second end that are positioned opposite to each other, and the cylinder body 32 has a first end and a second end that are positioned opposite to each other. Among them, the second end of the piston rod 31 is assembled on the first end of the cylinder body 32, and the first end of the piston rod 31 is exposed outside the cylinder body 32. When the piston rod 31 is hinged with the punch pendulum block 20, the first end of the piston rod 31 can be hinged with the punch pendulum block 20 through the third hinge shaft 33, and at this time, the second end of the cylinder body 32 can be hinged with the second support 40 through the second hinge shaft 41. Through this setting, the second hinge shaft 41, the cylinder body 32 and the piston rod 31 of the cylinder 30, and the third hinge shaft 33 can be basically distributed in a straight line, so that the piston rod 31 of the cylinder 30 can smoothly drive the punch pendulum block 20 to rotate relative to the first support 10 when it is extended or retracted. It should be understood that the positions at which the piston rod 31 and the cylinder body 32 are respectively hinged to the punch pendulum block 20 and the second support 40 are not limited to the end positions shown above. In addition, other position distribution methods can also be used.

[0049] Exemplary, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 , an adapter 50 may be fixedly connected to the punch pendulum block 20, and the adapter 50 is hinged to the piston rod 31 or the cylinder body 32 through the third hinge shaft 33. By using the adapter 50 to connect between the cylinder 30 and the punch pendulum block 20, when the second support 40 is located below the first support 10, it is convenient to hinge the punch pendulum block 20 with the cylinder 30. For example, refer to Figure 1 and Figure 2 , the adapter 50 can be fixed on the punch pendulum block 20 by a third screw 51. For example, refer to Figure 1 and Figure 2 The piston rod 31 and the adapter 50 can be hinged via a third hinge shaft 33 , and the third hinge shaft 33 is locked in the hinge holes of the piston rod 31 and the adapter 50 via a third cotter pin 34 .

By setting a special limiting structure, it is used to limit the rotation stop position of the punch swing block 20 relative to the first support 10 in one rotation direction or two rotation directions, and the rotation range of the punch swing block 20 is limited to prevent the punch swing block 20 from rotating outside the preset rotation range when the piston rod 31 is not accurately controlled. When setting the limiting structure, multiple methods can be used.

[0051] Exemplary, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the limiting structure may include: a first limiting structure 61 and a second limiting structure 62; wherein the first limiting structure 61 is configured such that when the punch swing block 20 rotates to the first set position around the first rotation direction 41, the first limiting structure 61 blocks the punch swing block 20 from continuing to rotate around the first rotation direction 41; the second limiting structure 62 is configured such that when the punch swing block 20 rotates to the second set position around the second rotation direction 72, the second limiting structure 62 blocks the punch swing block 20 from continuing to rotate around the second rotation direction 72; the first rotation direction 41 is opposite to the second rotation direction 72. Of course, in other embodiments, the limiting structure may include only the first limiting structure 61 or only the second limiting structure 62.

[0052] When setting the first limiting structure 61 and the second limiting structure 62, various methods can be used. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , exemplarily, the first limiting structure 61 and the second limiting structure 62 can be arranged on the first support 10; wherein the first limiting structure 61 is configured as follows: when the punch swing block 20 rotates to the first set position around the first rotation direction 41, the first limiting structure 61 abuts against the punch swing block 20 to prevent the punch swing block 20 from continuing to rotate around the first rotation direction 41; the second limiting structure 62 is configured as follows: when the punch swing block 20 rotates to the second set position around the second rotation direction 72, the second limiting structure 62 abuts against the punch swing block 20 to prevent the punch swing block 20 from continuing to rotate around the second rotation direction 72. Exemplarily, refer to Figure 1 and Figure 2 The first limiting structure 61 and the second limiting structure 62 can be fixed to the first support 10 by fourth screws 63 respectively to determine the positions of the first limiting structure 61 and the second limiting structure 62 in the X, Y, and Z directions.

[0053] Of course, in other embodiments, one or both of the first limiting structure 61 and the second limiting structure 62 can be set on the second support 40 to limit the rotation range of the cylinder 30, thereby indirectly limiting the rotation mode of the punch pendulum block 20.

[0054] Exemplary, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, the punch swing block 20 may have a first limiting surface 21 and a second limiting surface 22; wherein the first limiting surface 21 is configured such that when the punch swing block 20 rotates to the first set position around the first rotation direction 41, the first limiting surface 21 abuts against the first limiting structure 61 to ensure one of the working positions of the punch swing block 20; the second limiting surface 22 is configured such that when the punch swing block 20 rotates to the second set position around the second rotation direction 72, the second limiting surface 22 abuts against the second limiting structure 62 to ensure another working position of the punch swing block 20. Exemplarily, the first limiting surface 21 and the second limiting surface 22 may be located on opposite sides of the first hinge shaft 11, respectively, the first limiting structure 61 and the second limiting structure 62 may be located on opposite sides of the first hinge shaft 11, respectively, and the first limiting structure 61 is disposed opposite to the first limiting surface 21, and the second limiting structure 62 is disposed opposite to the second limiting surface 22. When the punch swing block 20 rotates to the first set position around the first rotation direction 41, the first limiting surface 21 just abuts against the first limiting structure 61, so that the first limiting structure 61 can prevent the punch swing block 20 from continuing to rotate along the first rotation direction 41. When the punch swing block 20 rotates to the second set position around the second rotation direction 72, the second limiting surface 22 just abuts against the second limiting structure 62, so that the second limiting structure 62 can prevent the punch swing block 20 from continuing to rotate along the second rotation direction 72. For example, Figure 5 As shown, the rotation angle of the punch pendulum block 20 between the first setting position and the second setting position is 23°.

[0055] Exemplary, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the first limiting structure 61 may include a limiting block, the upper end surface of the limiting block cooperates with the first limiting surface 21, so that the first limiting surface 21 abuts against the upper end surface of the limiting block, blocking the punch swing block 20 from further rotating in the first direction. Exemplarily, the first limiting structure 61 may also include a limiting column, the upper end surface of the limiting column cooperates with the first limiting surface 21, so that the first limiting surface 21 abuts against the upper end surface of the limiting block, blocking the punch swing block 20 from further rotating in the first direction. The number of limiting columns or limiting blocks is one, or two or more. When the number of limiting columns or limiting blocks is multiple, the heights of the multiple limiting columns or limiting blocks are equal, so that the upper end surfaces of the multiple limiting columns or limiting blocks abut against the first limiting surface 21 at the same time. Exemplarily, the limiting block or limiting column may be fixed to the first support 10 by means such as but not limited to screw fastening.

[0056] Exemplary, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the second limiting structure 62 may include a limiting block, the upper end surface of the limiting block cooperates with the first limiting surface 21, so that the first limiting surface 21 abuts against the upper end surface of the limiting block, blocking the punch swing block 20 from further rotating in the first direction. Exemplarily, the first limiting structure 61 may also include a limiting column, the upper end surface of the limiting column cooperates with the first limiting surface 21, so that the first limiting surface 21 abuts against the upper end surface of the limiting block, blocking the punch swing block 20 from further rotating in the first direction. The number of limiting columns or limiting blocks is one, or two or more. When the number of limiting columns or limiting blocks is multiple, the heights of the multiple limiting columns or limiting blocks are equal, so that the upper end surfaces of the multiple limiting columns or limiting blocks abut against the first limiting surface 21 at the same time. Exemplarily, the limiting block or limiting column may be fixed to the first support 10 by means such as but not limited to screw fastening.

One end of the air inlet pipe 81 is connected to the cylinder body 32 of the cylinder 30, and the other end of the air inlet pipe 81 is connected to the air inlet joint 83. One end of the air outlet pipe 82 is connected to the cylinder body 32 of the cylinder 30, and the other end of the air outlet pipe 82 is connected to the air outlet joint 84. Exemplarily, the air inlet joint 83 and the air outlet joint 84 may be fixed to an air pipe joint mounting plate 85 to ensure that the cylinder 30 can rotate around the second hinge shaft 41 and the third hinge shaft 33 after connecting to an external air source. Exemplarily, the air pipe joint mounting plate 85 may be fixed to an external support platform, support frame or other carrier by a fifth screw. The specific working principle is: after the workpiece to be stamped is placed on the clamping mechanism connected to the punch pendulum block 20, the external compressor provides an air source to drive the piston rod 31 of the cylinder 30 to perform telescopic movement, so that the punch pendulum block 20 can rotate around the first support 10, thereby meeting the conversion of the stamping angle of the workpiece between the front and rear processes in the automated production process and meeting the needs of automated production.

With the development of society, labor costs remain high, and labor panic is repeatedly staged. Based on the production concept of intelligent manufacturing, the workpiece angle adjustment mechanism shown in the embodiment of the present application is mainly suitable for some cold stamped workpieces when applied to stamping equipment.
