Description

Technical Field

[0001] The utility model relates to the technical field of stamping machine tooling, in particular to an opening and closing type stamping machine tooling. Background Technique

[0002] The stamping machine tooling is a tool designed to enable the stamping process to be completed more precisely and efficiently.

[0003] During the clamping of the workpiece to be stamped by the existing stamping machine tooling, it is generally fixed by the way of tightening with threads, resulting in high complexity in the loading and unloading operations of the workpiece each time, and lacking a set of clamping tooling structure that can be quickly opened and closed.

[0004] Based on the existing stamping machine tooling, there are the following disadvantages: during the clamping of the workpiece by the existing clamping tooling such as the screw type, a cumbersome tightening operation is required, so that the workpiece cannot realize rapid and continuous clamping, processing and stamping operations, resulting in low stamping operation efficiency. For this reason, we propose an opening and closing type stamping machine tooling. Summary of the Invention

[0005] The main purpose of the utility model is to provide an opening and closing type stamping machine tooling, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An opening and closing type stamping machine tooling includes a support seat, a fixed die and an opening and closing moving die, and further includes an oval pressing block, a chute and a slider. The fixed die is installed on one side of the top of the support seat through bolts. An opening and closing moving die is arranged on the side of the top of the support seat away from the fixed die. Chutes are respectively opened at both ends of the top of the support seat. Sliders corresponding to the chutes are respectively arranged at both ends of the bottom of the opening and closing moving die. The sliders are slidably connected with the chutes. An oval pressing block is arranged on one side of the support seat.

[0008] Furthermore, a cushion block integrated with the support seat is arranged on the support seat. A rotating rod is welded to the top of the cushion block. The center of the oval pressing block is sleeved on the rotating rod.

[0009] Furthermore, a grip rod is welded to one end of the oval pressing block.

[0010] Furthermore, a guide rod is arranged in the chute. The slider is sleeved on the guide rod.

[0011] Furthermore, a tension spring is sleeved on one end of the guide rod. Both ends of the tension spring are respectively welded to the slider and the end of the chute.

[0012] Compared with the prior art, the utility model has the following beneficial effects: A set of manually-operated clamping tooling for a stamping machine for continuous stamping processing is realized through a component composed of a support base, a fixed mold, an opening and closing movable mold, an oval pressing block, a chute and a slider. It can help operators flexibly clamp the workpieces to be stamped, and has an independent elastic opening mechanism. After the worker releases the hand, the opening and closing movable mold can automatically return to its position, greatly increasing the convenience of stamping processing, and solving the problem that during the clamping of workpieces by existing screw-type clamping tooling, cumbersome tightening operations are required, making it impossible to achieve rapid and continuous clamping, processing and stamping operations for workpieces, resulting in low stamping operation efficiency.

[0017] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0018] As Figures 1-3 shown, an opening and closing type stamping machine tooling includes a support base 1, a fixed mold 2 and an opening and closing movable mold 3, and further includes an oval pressing block 4, a chute 5 and a slider 7. The fixed mold 2 is installed on one side of the top of the support base 1 through bolts. An opening and closing movable mold 3 is arranged on the side of the support base 1 away from the fixed mold 2 at the top. Chutes 5 are respectively opened at both ends of the top of the support base 1. Sliders 7 corresponding to the chutes 5 are respectively arranged at both ends of the bottom of the opening and closing movable mold 3. The sliders 7 are slidably connected with the chutes 5. An oval pressing block 4 is arranged on one side of the support base 1. A cushion block 9 integrated with it is arranged on the support base 1. A rotating rod 10 is welded to the top of the cushion block 9. The center of the oval pressing block 4 is sleeved on the rotating rod 10. A grip rod 11 is welded to one end of the oval pressing block 4.

[0019] Wherein, a guide rod 6 is arranged in the sliding groove 5, the slider 7 is sleeved on the guide rod 6, one end of the guide rod 6 is sleeved with a tension spring 8, and two ends of the tension spring 8 are respectively welded to the slider 7 and the end of the sliding groove 5; the tension spring 8 can pull the opening and closing moving die 3 back automatically.

[0020] It should be noted that the present utility model is a kind of opening and closing type stamping machine tooling. During operation, a person assembles the support base 1 of the present application on the stamping table of the stamping machine, and it can be installed by bolts or welding. During operation, a worker feeds and unloads the stamping workpiece with one hand, and grasps the grip rod 11 of the elliptical pressing block 4 with the other hand. After the workpiece enters between the fixed die 2 and the opening and closing moving die 3, the person pushes and rotates the elliptical pressing block 4 through the grip rod 11, so that the end of the elliptical pressing block 4 pushes against the opening and closing moving die 3, so that the opening and closing moving die 3 can press against the fixed die 2, achieving clamping treatment for the workpiece. Then the stamping machine processes the workpiece by stamping. After stamping is completed, the person releases the grip rod 11 and takes out the stamped workpiece product. Moreover, after the opening and closing moving die 3 loses the external pushing pressure, the opening and closing moving die 3 can return to its original position based on the pulling back of the tension spring 8, leaving the pressing against the fixed die 2. During this period, the worker can place the next group of workpieces to be stamped between the fixed die 2 and the opening and closing moving die 3 again. By repeating this process, continuous stamping processing can be carried out quickly.

[0021] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
