Description

Technical Field

[0001] This utility model relates to the field of hot riveting fixture technology, specifically a hot riveting fixture for riveting plastic rivets to products. Background Technology

[0002] This specialized thermal riveting fixture is used to securely fasten plastic rivets to products by heating them. The fixture utilizes heat energy to soften the plastic rivets, then applies mechanical pressure to deform them and bond them tightly to the product, achieving a stable riveting effect. This equipment is widely used in the assembly process of various plastic products, ensuring reliable riveting quality and improving the overall structural strength and durability of the product. Based on actual usage, the existing technology has some drawbacks, such as poor cooling effect. Plastic products placed on the riveting table are prone to sticking to the top of the riveting table due to the height generated during hot riveting, which can lead to difficulty in removal or damage to the product. Therefore, we have improved the existing technology based on actual usage. Utility Model Content

An electric push rod 10 is provided at the bottom of the crossbar 9 away from the column 8, and a pressure plate 11 is provided at the bottom of the electric push rod 10. When the product is placed on the top of the riveting platform 7, the electric push rod 10 can move up and down with the pressure plate 11 by extension and retraction, so as to clamp the product and fix it on the top of the riveting platform 7. The bottom of the riveting table 7 is provided with an S-shaped mounting groove 12 from left to right. A coolant flow pipe 13 is installed in the S-shaped mounting groove 12. The two ends of the coolant flow pipe 13 are located on the left and right sides of the rear end face of the riveting table 7, and both ends of the coolant flow pipe 13 are provided with connectors 14. One end of the coolant flow pipe 13 is connected to a coolant inlet pipe 15 through the connector 14, and the other end of the coolant flow pipe 13 is connected to a coolant outlet pipe 16 through the connector 14. The end of the coolant inlet pipe 15 away from the connector 14 is connected to a coolant supply pipe, which is connected to an external evaporator. The evaporator is attached to the surface of the coolant supply pipe and is connected to an external liquid refrigeration device. The coolant flows through the coolant inlet pipe 15 into the coolant flow pipe 13 and diffuses outward through the S-shaped mounting groove 12, providing uniform and efficient cooling to the entire riveting table 7. The coolant is finally discharged through the coolant outlet pipe 16, thus achieving a circulating cooling effect.

[0022] Preferably, a solenoid valve 17 is provided on both the coolant inlet pipe 15 and the coolant outlet pipe 16, and an adapter 18 is provided at the end of both the coolant inlet pipe 15 and the coolant outlet pipe 16 away from the connector 14.
