[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0024] The present invention will now be described in further detail:
[0025] like Figures 1 to 6 The diagram shows a simple manual punching fixture, including a bracket, an operating arm 1, a connecting rod 2, a guide cylinder 3, a punch 4, and a punch 5. The front end of the operating arm 1 is configured as an L-shaped structure. The upper end of the L-shaped structure is hinged to the guide cylinder 3 to form a first rotational connection, i.e., the upper end of the L-shaped structure is provided with a first rotational connection 6. The lower end of the L-shaped structure is hinged to the upper end of the connecting rod 2 to form a second rotational connection, i.e., the lower end of the L-shaped structure is provided with a second rotational connection 7. The lower end of the connecting rod 2 is hinged to the upper end of the punch 4. The punch 4 is sleeved with the guide cylinder 3. The lower end of the punch 4 is connected to the punch 5. When the operating arm 1 swings downward, the operating arm 1 drives the punch 4 to punch downward. When the operating arm 1 swings upward, the operating arm 1 drives the punch 4 to return to its original position.
[0026] The support includes a worktable, a guide cylinder 3 is installed on the upper side of the worktable, the lower end of the punch 4 is punched relative to the worktable, and the worktable is provided with a through hole 8 that mates with the punch 5.
[0027] like Figure 3 As shown, from a mechanical principle perspective, the L-shaped structure can be viewed as a crank, and the punch 4 is a linearly moving slider. Therefore, the reciprocating up and down operation of the L-shaped structure by the operating arm 1 can drive the punch 4 to move linearly up and down, thereby realizing the stamping process. In addition, the operating arm 1 utilizes the lever principle to amplify the force, which is beneficial for realizing manual stamping operation.
[0028] In order to make the manipulator 1 move up and down more effectively, such as Figure 5 ,6 As shown, the front side wall of the guide cylinder 3 is provided with a guide groove 22 from the top to the bottom along the axial direction. The operating arm 1 is guided and cooperated with the guide groove 22. When the operating arm 1 swings up and down, it is guided by the guide groove 22.
[0029] To facilitate the replacement of different punches 5, such as Figure 4 , 5 As shown, the lower ends of the punch 5 and the punch column 4 are detachably connected by the sixth bolt 23.
[0030] This disclosure is generally divided into two parts: a stamping structure and a bracket. The stamping structure is based on the guide cylinder 3 connected together to form a first component, while the bracket is the second component. By connecting the first component and the second component, a simple manual punching fixture of this disclosure is constituted.
[0031] In some embodiments, such as Figure 1 As shown, the support also includes a base plate 9, a column 10, and a first transverse support plate 11. The column 10 is mounted on the base plate 9, and the worktable is configured as a second transverse support plate 12. The first transverse support plate 11 and the second transverse support plate 12 are arranged parallel to each other in the vertical direction, and the inner ends of the first transverse support plate 11 and the second transverse support plate 12 are both mounted on the column 10. This provides good support mechanical performance.
[0032] In some embodiments, such as Figure 2 , 4 As shown, the base plate 9 and the column 10 are connected by the first bolt 13, and the inner ends of the first transverse support plate 11 and the second transverse support plate 12 are both connected to the column 10 by the second bolt 14. In this way, the bracket (second component) is designed to be detachable, which is beneficial to manufacturing and easy to assemble and disassemble, which in turn facilitates transportation or movement.
[0033] In some embodiments, such as Figure 1 , 3 As shown in Figure 4, a first supporting triangular plate 15 is provided on the upper side of the first transverse support plate 11. The front side of the first supporting triangular plate 15 abuts against the rear side of the guide cylinder 3, and the lower side of the first supporting triangular plate 15 is connected to the first transverse support plate 11 by a third bolt 16. In this way, on the one hand, the guide cylinder 3 is better supported, maintaining the fixed state of the guide cylinder 3 during stamping; on the other hand, the detachable design facilitates disassembly and assembly, which in turn facilitates transportation or movement.
[0034] In some embodiments, such as Figure 1 , 3As shown in Figure 4, a second supporting triangle 17 is provided on the lower side of the second transverse support plate 12. The rear side of the second supporting triangle 17 abuts against the front side of the column 10, and the upper side of the second supporting triangle 17 is connected to the second transverse support plate 12 by a fourth bolt 18. In this way, on the one hand, the second transverse support plate 12, i.e. the worktable, is better supported, maintaining the support capacity of the worktable during stamping; on the other hand, the detachable design facilitates disassembly and assembly, which in turn facilitates transportation or movement.
[0035] In some embodiments, such as Figure 1 , 2 As shown in Figure 5, the first transverse support plate 11 is provided with a clamping part 19 for connecting the guide cylinder 3. The clamping part 19 includes left and right parts and is locked and fixed to the guide cylinder 3 by the fifth bolt 20. In this way, the first component is detachably connected to the first transverse support plate 11, so that the first component and the second component can be easily separated for convenient transportation or movement.
[0036] Specifically, adjusting the height of the guide cylinder 3 and then locking it can be used to adjust the height of the punch 4, thereby adapting to the stroke of the punch 5. This allows for more flexible use.
[0037] In some embodiments, such as Figure 1 As shown, a U-shaped support frame 21 is connected to the front end of the base plate 9. The U-shaped support frame 21 is located on the same side as the operating arm 1. The U-shaped support frame 21 is used to expand the support of the base plate 9 and also serves as a handle for moving. In this way, the support capacity of the support is improved on the one hand, and the moving is also convenient on the other hand.
[0038] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
