[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] According to the attached Figure 1 、 2 As shown in , 5: The utility model provides a stamping tool for a workpiece silencer groove: it includes a press body, the press body includes a placing table 9, and a pressing seat 10 arranged above the placing table, the placing table 9 is provided with a lower base 1, and the pressing seat 10 is provided with an upper base 5 placed above the lower base 1, the sizes of the lower base 1 and the upper base 5 can be adjusted according to different press models and product shapes, and a positioning plate 2 is provided on the top of the lower base 1. The positioning plate 2 of corresponding specifications is selected according to the characteristics of different products, which is used for clamping and positioning the workpiece product, positioning the stamping position, and ensuring that the workpiece silencer groove to be stamped is placed directly under the stamping tool. The positioning plate 2 needs to be designed and adjusted according to the product structure. On the one hand, the product needs to be fixed and clamped conveniently. On the other hand, the fitting clearance with the product needs to be adjusted according to the actual production situation. If the fitting clearance is too small, it will make it difficult to pick up the product after the tool is pressed down. If the fitting clearance is too large, the product will be offset after the tool is pressed down, affecting the stamping position and size.

[0020] According to the attached Figure 1、 3 4: A tool clamping body 4 is provided at the bottom of the upper base 5, and an embossing tool 8 is provided in the tool clamping body 4. The shape and size of the tool clamping body 4 can be adjusted according to different embossing tools 8. The tip of the embossing tool 8 needs to be contoured according to the specifications of the silencer groove of the workpiece product. The length of the embossing tool 8 can be adjusted according to the height of the tooling. The pressure seat 10 and the upper base 5, the upper base 5 and the tool clamping body 4, and the tool clamping body 4 and the limit plate 6 are all fixedly connected by screws, and the screws are mostly M8-M12.

[0021] According to the attached Figure 1 、 4 As shown: symmetrical positioning pins 3 passing through the positioning plate 2 are provided on both sides of the top of the lower base 1, and pin holes through which the positioning pins 3 pass are provided on the positioning plate 2 and the clamping tool body 4, which are used to find the correct stamping position. A limiting plate 6 through which the stamping tool 8 passes is provided at the bottom of the clamping tool body 4, which is used to fix the tool position and prevent the tool from shifting. A knife pad 7 is provided between the bottom of the clamping tool body 4 and the top of the limiting plate 6. Knife pads 7 of different specifications are used to adjust the height of the stamping tool 8, increase or decrease the stroke of the stamping tool 8, and ensure the consistency of the stamping when the stamping tool 8 is pressed down.

[0022] According to the attached Figure 1 、 6 As shown: a locking bolt for locking the stamping tool 8 is provided on the side wall of the tool clamping body 4, a through hole for the stamping tool 8 to pass through is provided in the tool clamping body 4, a locking hole 11 matching the locking bolt is provided on the stamping tool 8, and a threaded hole that penetrates the locking hole 11 and matches the locking bolt is provided on the side wall of the tool clamping body 4. The tool clamping body 4 is used to fix the stamping tool 8. By screwing the locking bolt into the threaded hole and passing through the locking hole 11, the position of the stamping tool 8 can be locked in the through hole in the tool clamping body 4.

[0023] Principle of the utility model

[0024] During use, the tool product is placed on the positioning plate 2 for clamping and positioning, and the imprinting position is determined to ensure that the silencer groove of the workpiece to be imprinted is placed directly below the imprinting tool. The press body is operated to press the pressure seat 10 downward, thereby driving the upper base 5, the clamping tool body 4, the imprinting tool 8, and the limit plate 6 to move downward. After the imprinting tool 8 moves down to a certain position, the silencer groove of the workpiece is imprinted. The limit plate 6 is used to fix the tool position to prevent the tool from shifting. The utility model can be adapted to different presses and product forms, and can be appropriately adjusted according to the structure of the workpiece product. After installation, large-scale batch production can be achieved through simple debugging. It is easy to operate and highly practical. It can imprint the silencer groove of the workpiece with high precision, which can greatly improve production efficiency.
