Description

Technical Field

[0001] This application relates to the technical field of silicone pad testing, and in particular to a stamping structure for testing the performance of silicone pads. Background Technology

[0002] After the silicone pad is processed, it needs to be stamped with a stamping structure to create dumbbell-shaped slots before mechanical property testing.

[0003] Currently, Chinese patent CN207172284U discloses a dual-wheel manual die-cutting machine, including a worktable, a crossbeam, support rods, an upper pressure plate, a shaft, eccentric wheels, a column, a spring, and an adjusting rod. The bottom ends of the two support rods are fixed to the two ends of the worktable, and the crossbeam is sleeved on the support rods and threaded to them, allowing the crossbeam to slide up and down along the support rods. The upper pressure plate is located between the crossbeam and the worktable. The column passes through the crossbeam, and its bottom end is fixed to the upper pressure plate. There are two eccentric wheels, with an eccentric pressure shaft connecting them. The eccentric wheel is located at the top of the column, and a spring is sleeved on the column above the crossbeam. The eccentric wheel is sleeved on the shaft, which is fixed to the crossbeam via the adjusting rod. A long rod-shaped pressure rod is fixed on the shaft, and the upper pressure plate has die-cutting mounting holes.

[0004] When a die cutter is installed in the die-cutting mounting hole of the upper pressure plate, rotating the pressure rod causes the upper pressure plate to move, which in turn moves the die cutter. If the die cutter continues to move after processing the silicone pad, it will violently impact the worktable, causing damage. Subsequent processing of the silicone pad with a damaged die cutter will also damage the silicone pad, resulting in substandard product quality. Utility Model Content

[0005] To ensure the quality of the processed product, this application provides a stamping structure for testing the performance of silicone.

[0006] This application provides a stamping structure for testing the performance of silicone, which adopts the following technical solution: A stamping structure for testing the performance of silicone includes a fixed frame, a lifting block, a stamping block, a first spring, a support block, an adjusting shaft, an eccentric wheel, and a lever. The lifting block is slidably mounted on the fixed frame, and the stamping block is mounted on the lifting block. One end of the first spring is connected to the lifting block, and the other end is connected to the fixed frame. The support block is mounted on the fixed frame, the adjusting shaft is rotatably mounted on the support block, and the eccentric wheel is mounted on the adjusting shaft and abuts against the lifting block. The lever is mounted on the adjusting shaft. The structure also includes a blocking mechanism comprising a first fixed block and an abutting block. The first fixed block is mounted on the support block, and the abutting block is mounted on the adjusting shaft, and the abutting block is capable of abutting against the first fixed block.

[0007] By adopting the above technical solution, rotating the lever drives the adjusting shaft to rotate, and the eccentric wheel on the adjusting shaft pushes the lifting block to move. The lifting block drives the stamping block to move, causing the stamping block to perform a stamping action. When the adjusting shaft rotates, it drives the abutting block to move. When the abutting block abuts the first fixed block, it indicates that the stamping action is completed. Because the first fixed block blocks the abutting block, the adjusting shaft cannot continue to rotate. Therefore, the blocking mechanism can reduce the need for continued stamping action after the stamping is completed, thereby ensuring the quality of the processed product.

[0008] Optionally, the adjusting shaft has multiple slots, and the abutment block engages with one of the slots.

[0009] By adopting the above technical solution, the contact block can be engaged with the slots at different positions, allowing the stamping block to move to different positions, thereby improving its applicability.

[0010] Optionally, the adjusting shaft is provided with a fixing component, which includes a fixing rod, a second fixing block, and a fixing bolt. The adjusting shaft has a first through hole communicating with the slot, the abutment block has a fixing groove, the fixing rod is disposed on the second fixing block, and the end of the fixing rod away from the second fixing block passes through the first through hole and engages with the fixing groove; the fixing bolt passes through the second fixing block and is threadedly connected to the adjusting shaft.

[0011] By adopting the above technical solution, after the abutment block is engaged with the slot, the end of the fixing rod away from the second fixing block passes through the first through hole and engages with the fixing slot on the abutment block; then the fixing bolt passes through the second fixing block and is threadedly connected to the adjusting shaft, so that the abutment block will be stably connected to the adjusting shaft.

[0012] Optionally, the adjustment shaft is provided with a connecting mechanism connected to the lever. The connecting mechanism includes a first connecting block, a second connecting block, and an adjustment component. The first connecting block is disposed on the lever, and the adjustment shaft has a first connecting groove that engages with the first connecting block. The second connecting block is slidably disposed on the adjustment shaft through the adjustment component, and the first connecting block has a second connecting groove that engages with the second connecting block.

[0013] By adopting the above technical solution, a suitable lever is selected, and then the lever is engaged with the first connecting groove. Then, the second connecting block is moved by the adjusting component, so that the second connecting block is engaged with the second connecting groove on the first connecting block, thereby fixing the first connecting block on the adjusting shaft. Therefore, the connection mechanism can connect a suitable lever to the adjusting shaft according to the operator's habits, thus improving applicability.

[0014] Optionally, the adjustment assembly includes an adjustment shaft, an adjustment gear, and an adjustment rack. The adjustment shaft is rotatably mounted on the adjustment shaft, and the adjustment gear is keyed to the adjustment shaft. The adjustment rack is mounted on the second connecting block and meshes with the adjustment gear.

[0015] By adopting the above technical solution, rotating the adjusting shaft will cause the adjusting gear on the adjusting shaft to move the adjusting rack, which in turn will cause the second connecting block to move.

[0016] Optionally, the support block has a second through hole, and the adjusting shaft includes a first rotating shaft, a second rotating shaft, a limiting block, a second spring, and a connecting bolt. The eccentric wheel and the lever are both disposed on the first rotating shaft. The first rotating shaft has a first groove and a limiting groove communicating with the first groove. The second rotating shaft is slidably disposed in the first groove. The limiting block is disposed on the second rotating shaft and slidably connected to the limiting groove. One end of the second spring is connected to the first rotating shaft, and the other end is connected to the second rotating shaft. The connecting bolt passes through the first rotating shaft and is bolted to the second rotating shaft. The end of the second rotating shaft away from the first rotating shaft passes through the second through hole on the support block, and the abutment block is disposed on the end of the second rotating shaft that passes through the second through hole.

[0017] By adopting the above technical solution, when the adjusting shaft is to be installed on the support block, the operator pushes the second rotating shaft so that the second rotating shaft enters the first groove, and the second spring deforms; then the first rotating shaft abuts against the support block. When the second rotating shaft is aligned with the second through hole, the force of the second spring restoring its elastic deformation drives the second rotating shaft to rotate, so that the end of the second rotating shaft away from the first rotating shaft passes through the second through hole. Finally, the connecting bolt passes through the first rotating shaft and is threadedly connected to the second rotating shaft.

[0018] Optionally, the adjusting shaft is provided with a mounting assembly connected to the eccentric wheel. The mounting assembly includes a positioning block and a mounting bolt. The positioning block is disposed on the adjusting shaft. The eccentric wheel has a third through hole for the adjusting shaft to pass through. The eccentric wheel has a positioning groove that engages with the positioning block. The mounting bolt passes through the eccentric wheel and is threadedly connected to the adjusting shaft.

[0019] By adopting the above technical solution, the adjusting shaft passes through the third through hole on the eccentric wheel, and the positioning block is engaged with the positioning groove on the adjusting shaft. Finally, the mounting bolt passes through the eccentric wheel and is threadedly connected to the adjusting shaft, so that the eccentric wheel can be detachably connected to the adjusting shaft.

[0020] Optionally, a rubber sleeve is fitted onto the eccentric wheel, and the rubber sleeve abuts against the lifting block.

[0021] By adopting the above technical solution, the rubber sleeve can reduce the wear of the eccentric wheel and the lifting block.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The blocking mechanism can reduce the need for continued stamping after the stamping process is completed, thereby ensuring the quality of the processed product; 2. By engaging the contact block with slots at different positions, the stamping block can be moved to different positions, thereby improving its applicability. Attached Figure Description
