Embodiment

[0022] Please refer to Figures 1 - 4 , a clamping tooling for a double-headed punch bar, including a punch bar clamping seat 1, a linkage fastening mechanism 2 and an independent fastening mechanism 3. A plurality of punch bar clamping holes 11 are uniformly arranged along a straight line direction on the top of the punch bar clamping seat 1. The punch bar clamping holes 11 penetrate through the bottom of the punch bar clamping seat 1. The aperture sizes of the punch bar clamping holes 11 match the sizes of the double-headed punch bar. The double-headed punch bar can extend into the punch bar clamping holes 11. The linkage fasteners 22 of the linkage fastening mechanism 2 and the independent fasteners 31 of the independent fastening mechanism 3 both move towards the double-headed punch bar in the punch bar clamping holes 11 and squeeze the double-headed punch bar, so as to clamp the double-headed punch bar into the punch bar clamping holes 11 to realize the clamping of the double-headed punch bar. Opposite two side surfaces of the punch bar clamping seat 1 are respectively provided with a linkage fastening end surface and an independent fastening end surface. The linkage fastening end surface is used for installing the linkage fastening mechanism 2, and the independent fastening end surface is used for installing each independent fastening mechanism 3.

[0023] Linkage fastening holes are arranged at positions corresponding to the punch bar clamping holes 11 on the linkage fastening end surface. Each linkage fastening hole communicates with the corresponding punch bar clamping hole 11. The linkage fastening mechanism 2 is arranged on one side of the linkage fastening end surface of the punch bar clamping seat 1. The linkage fastening mechanism 2 includes a driving part 21 and a linkage fastener 22. Each linkage fastener 22 is respectively movably penetrated through each linkage fastening hole. The driving part 21 is a cylinder or other forms of telescopic parts. The driving part 21 is installed on one side of the linkage fastening end surface. The action part of the driving part 21 is connected with each linkage fastener 22. The driving part 21 drives each linkage fastener 22 to move between a linkage fastening position and a linkage releasing position along the linkage fastening hole where it is located.

[0024] When all the independent fasteners 31 of each independent fastening mechanism 3 are in the independent fastening positions, when all the linkage fasteners 22 are in the linkage fastening positions, the linkage fasteners 22 cooperate with the independent fasteners 31 to clamp the double-headed punch bars in each punch bar clamping hole 11. When all the linkage fasteners 22 are in the linkage release positions, the linkage fasteners 22 and the independent fasteners 31 cannot clamp the double-headed punch bars in each punch bar clamping hole 11.

[0025] Independent fastening holes are provided at positions corresponding to each punch bar clamping hole 11 on the independent fastening end face, and each independent fastening hole communicates with the corresponding punch bar clamping hole 11. On one side of the independent fastening end face of the punch bar clamping seat 1, an independent fastening mechanism 3 is provided at each independent fastening hole. The independent fastening mechanism 3 includes an independent fastener 31, and the independent fastener 31 is inserted into the independent fastening hole. The independent fastener 31 can move between an independent fastening position and an independent release position along the independent fastening hole under manual or driving device drive, and the actions of the independent fasteners 31 are independent of each other.

[0026] When all the independent fasteners 31 are in the independent fastening positions, when all the linkage fasteners 22 of the linkage fastening mechanism 2 are in the linkage fastening positions, the independent fasteners 31 and the linkage fasteners 22 cooperate to clamp the double-headed punch bars in each punch bar clamping hole 11. When all the linkage fasteners 22 of the linkage fastening mechanism 2 are in the linkage release positions, the double-headed punch bars in each punch bar clamping hole 11 are not clamped. When one or more independent fasteners 31 are in the independent release positions, regardless of the position states of the linkage fasteners 22, the double-headed punch bars corresponding to the independent fasteners 31 in the independent release positions cannot be clamped.

[0027] During the production and processing process, when the double-headed punch bars in each punch bar clamping hole 11 are all clamped, when it is found that one or more double-headed punch bars have abnormal conditions and need to be taken out, the independent fastener 31 corresponding to the double-headed punch bar can be moved from the independent fastening position to the independent release position, so as to remove the double-headed punch bar from the punch bar clamping seat 1.

[0028] To achieve a better clamping effect on the double-headed punch bars, the ends of the independent fastener 31 and the linkage fastener 22 are both provided with a card slot, and the card slot is an arc-shaped slot suitable for the external shape of the double-headed punch bar. The slot walls of each card slot are provided with anti-slip lines.

[0029] To ensure that the driving member 21 can drive all the linkage fasteners 22 to move simultaneously, a connecting plate 23 is provided at the action part of the driving member 21, and all the linkage fasteners 22 are connected to the connecting plate 23. The driving member 21 can also be provided as two or more, and all the driving members 21 move synchronously and have the same motion state, and the connecting plate 23 is connected to the action parts of all the moving members.

[0030] Please refer to Figure 2 and Figure 3The independent fastening mechanism 3 also includes a mounting arm 32, a swing arm 33 and a reset spring 34. The mounting arm 32 is arranged on the independent fastening end surface and is located above the independent fastening hole. One end of the swing arm 33 is connected to the mounting arm 32 and the swing arm 33 swings relative to the mounting arm 32. The rotation axis of the swing arm 33 is parallel to the independent fastening end surface. An independent fastener 31 is arranged on the swing arm 33. The independent fastener 31 is movably arranged in the independent fastening hole. The independent fastening hole is an arc hole. The virtual center of the independent fastening hole coincides with the rotation axis of the swing arm 33. The arm 33 rotates relative to the mounting arm 32 and drives the independent fastener 31 to move along the independent fastening hole between the independent fastening position and the independent loosening position. When the swing arm 33 swings toward the independent fastening end face, it drives the independent fastener 31 to move toward the independent fastening position. When the swing arm 33 swings away from the independent fastening end face, it drives the independent fastener 31 to move toward the independent loosening position. The swing arm 33 is connected to the independent fastening end face by a reset spring 34. The reset spring 34 pulls the swing arm 33 to move toward the independent fastening end face so that the independent fastener 31 has a tendency to move toward the independent fastening position.

[0031] During the production process, the position of the independent fastener 31 can be adjusted by moving the swing arm 33. After loosening the swing arm 33, the swing arm 33 is reset under the action of the reset spring 34 and drives the independent fastener 31 to move to the independent fastening position.

[0032] In order to limit the position of the swing arm 33 and prevent the swing arm 33 from being too close to the independent fastening end face so that the independent fastener 31 continuously moves into the independent fastening hole, a reset adjustment screw 35 is provided on the swing arm 33. Rotating the reset adjustment screw 35 can realize axial movement of the reset adjustment screw 35. Preferably, the reset adjustment screw 35 is perpendicular to the swing arm 33, and the end of the reset adjustment screw 35 abuts against the independent fastening end face when the independent fastener 31 is in the independent fastening position.

[0033] Please refer again Figure 2 and Figure 3 As a preferred embodiment, the independent fastening mechanism 3 also includes a support member 36, which is hinged to the bottom end of the swing arm 33 through a reset hinge. The support member 36 is provided with a punch rod support portion. When the independent fastener 31 is in the independent fastening position, the punch rod support portion is below the punch rod clamping hole 11. At this time, under the action of the support member 36, after the punch rod is added to each punch rod clamping hole 11, the support member 36 supports and lifts the double-headed punch, thereby preventing the double-headed punch from slipping out from the bottom of the punch rod clamping hole 11 when the double-headed punch is not clamped.

[0034] The supporting member 36 of each independent fastening mechanism 3 can be rotatably adjusted, so as to facilitate taking out a double-headed punch from the punch clamp hole 11.

[0035] Under the action of the reset hinge, the support member 36 has a tendency to flip towards the punch holder 1. In order to ensure that the position of the support member 36 enables the double-headed punch to be in a proper position state when passing through the punch clamping hole 11, a support adjustment screw 37 is provided on the support member 36. The support adjustment screw 37 can rotate relative to the support member 36. By rotating the support member 36, the position of the support adjustment screw 37 can be adjusted axially. When the independent fastener 31 is in the independent fastening position, the end of the support adjustment screw 37 abuts against the bottom end of the punch holder 1.

[0036] In order to deal with the situation where multiple or all double-headed punches are removed from the clamping tooling simultaneously, a linkage fitting ring 38 is provided at the bottom of the support member 36. By passing a long rod through the linkage fitting rings 38 of each support member 36, multiple support members 36 can be flipped simultaneously. At the same time, the fitting ring can also serve as a handle for flipping the support member 36.

[0037] In some embodiments, there are two punch holders 1 arranged side by side. An installation gap is reserved between the two punch holders 1. Linkage fastening end faces are provided on the opposite side end faces of the two punch holders 1. Linkage fastening mechanisms 2 are provided on the linkage fastening end faces of the two punch holders 1, and both linkage fastening mechanisms 2 are within the installation gap.
