Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rubber material stamping equipment, and in particular to a high-efficiency and stable small rubber material stamping and blanking machine. Background Technology
[0002] When conducting tensile tests on vulcanized rubber or thermoplastic rubber, a dumbbell-shaped specimen needs to be cut. Cutting the specimen requires a small stamping blanking machine. Existing small stamping blanking machines require multiple stamping operations when stamping thicker or more difficult-to-cut materials. After each stamping, the die needs to be lifted to determine if the specimen has been completely cut. If it has, the specimen will adhere to the die when it is lifted. If the specimen has not been cut, it will not be removed with the die, requiring the die to be placed back in place for a second stamping. However, misalignment of the indentation can occur when placing the die again. This process is not only time-consuming and labor-intensive but can also lead to damage to the stamped specimen, hindering subsequent experiments. Improvements are urgently needed. Utility Model Content
[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a highly efficient and stable small rubber material stamping and blanking machine, comprising a blanking machine body, a stamping table, and a stamping mechanism. The stamping table is mounted on the blanking machine body, and the stamping mechanism is mounted on the blanking machine body above the stamping table. The stamping table is equipped with a mold clamping device for installing stamping dies. The mold clamping device includes a pair of movable clamping plates, a pair of mounting clamping plates, and a pair of limiting screws for temporarily limiting the movable clamping plates. A pair of movable mounting plates are symmetrically provided at the bottom of each of the movable clamping plates, and each of the movable mounting plates is provided with a slider. Sliding grooves matching the sliders are opened on both sides of the stamping table. The pair of limiting screws are all located on the movable mounting plates and are threadedly connected to the movable mounting plates. Each of the movable clamping plates is provided with a lifting mechanism, and the pair of mounting clamping plates are all connected to the lifting mechanism.
[0004] Using the above technical solution, a mold clamping device is set on the stamping table, including a pair of movable clamps, a pair of mounting clamps, and a pair of limiting screws for temporary limiting of the movable clamps. When cutting the sample, the sample is first placed on the stamping table, then the mold is placed on the sample. The position of the pair of movable clamps is adjusted, and then the mold is raised and suspended in the air so that the pair of mounting clamps clamp the two ends of the mold. Then, the pair of limiting screws are tightened in sequence to limit the mold. After that, the stamping blanking machine is started to perform the first stamping. If the sample is not completely cut off in the first stamping, after the stamping mechanism is reset, the pair of mounting clamps are reset under the action of the lifting mechanism, and the mold is lifted up, so that the second stamping can be performed immediately without adjusting the position of the mold. The mold can perform the second stamping along the position of the first stamping. If the sample is completely cut off after the second stamping, the cut sample will be lifted up with the mold and can be removed manually.
[0005] A further feature of this invention is that the lifting mechanism includes a connecting rod and a compression spring. Each of the pair of movable clamps has a lifting groove that matches the connecting rod. The connecting rod and the compression spring are both located in the lifting groove. The two ends of the compression spring are respectively connected to the bottom of the connecting rod and the lifting groove. One end of the connecting rod is fixedly connected to the mounting clamp.
[0006] Using the above technical solution, since the lifting mechanism includes a connecting rod and a compression spring, each of the pair of movable clamps has a lifting groove that matches the connecting rod. The connecting rod and the compression spring are both set in the lifting groove. The two ends of the compression spring are respectively connected to the bottom of the connecting rod and the lifting groove. One end of the connecting rod is fixedly connected to the mounting clamp. After one downward press is completed, the movable clamp will be lifted and reset under the action of the compression spring.
[0007] A further feature of this invention is that each of the pair of movable clamping plates is provided with a rubber pad for convenient mold clamping.
[0008] By adopting the above technical solution, since both of the pair of movable clamping plates are provided with rubber pads for convenient mold clamping, the stability of mold clamping can be improved.
[0009] A further feature of this invention is that the stamping platform is also provided with an elastic clamp for temporarily holding the sample material, and the elastic clamp is rotatably connected to the stamping platform.
[0010] By adopting the above technical solution, since the stamping table is also provided with an elastic clamp for temporarily holding the sample material, the elastic clamp is rotatably connected to the stamping table. The sample material can be clamped by the elastic clamp, avoiding the problem of misalignment during secondary stamping caused by the mold being lifted and the sample moving.

[0015] By setting a mold clamping device on the stamping table, including a pair of movable clamps, a pair of mounting clamps, and a pair of limiting screws for temporary limiting of the movable clamps, when cutting the sample, the sample is first placed on the stamping table, then the mold is placed on the sample, the position of the pair of movable clamps is adjusted, and then the mold is raised and suspended in the air so that the pair of mounting clamps clamp the two ends of the mold. Then, the pair of limiting screws are tightened in sequence to limit the mold. After that, the stamping blanking machine is started to perform the first stamping. If the sample is not completely cut off in the first stamping, after the stamping mechanism is reset, the pair of mounting clamps are reset under the action of the lifting mechanism, and the mold is lifted up, so that the second stamping can be performed immediately without adjusting the position of the mold. The mold can perform the second stamping along the position of the first stamping. If the sample is completely cut off after the second stamping, the cut sample will be lifted up with the mold and can be removed manually.

The connecting rod and the compression spring are both located in the lifting groove. The two ends of the compression spring are respectively connected to the bottom of the connecting rod and the lifting groove. One end of the connecting rod is fixedly connected to the mounting clamp. After one downward press is completed, the movable clamp will be lifted and reset under the action of the compression spring.
[0018] Each of the pair of movable clamping plates is provided with a rubber pad 15 for convenient mold clamping.
[0019] Since both of the movable clamping plates are equipped with rubber pads for easy mold clamping, the stability of mold clamping can be improved.
[0020] The stamping platform is also provided with an elastic clamp 16 for temporary clamping of the sample material, and the elastic clamp is rotatably connected to the stamping platform.
[0021] Since the stamping platform is also equipped with an elastic clamp for temporarily holding the sample material, the elastic clamp is rotatably connected to the stamping platform. The sample material can be clamped by the elastic clamp, avoiding the problem of misalignment during secondary stamping caused by the mold being lifted and the sample moving.
