DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] Please refer to Figures 1 to 5 , the embodiment of the present application provides a riveting device for the production of embedded channel, including a frame 1 and a high-frequency induction heating machine 2. The frame 1 includes a workbench 3. The high-frequency induction heating machine 2 includes a heating induction coil 4 located above the workbench 3, and the main body of the high-frequency induction heating machine 2 is located below the workbench 3;

[0022] The frame 1 further includes a left side plate 5, a right side plate 6, and a top plate 7. The left side plate 5 and the right side plate 6 are respectively located on the left and right sides of the workbench 3, and the top plate 7 is located above the workbench 3. The left side plate 5 and the right side plate 6 are both fixedly connected to the workbench 3, and the top plate 7 is fixedly connected to the left side plate 5;

[0023] A backing plate 8 is fixed on the workbench 3. The setting of the backing plate 8 facilitates the placement of the channel body 24;

[0024] A left linear actuator 9 is installed on the left side plate 5. The left linear actuator 9 is selected as a hydraulic cylinder, and an electric cylinder or a pneumatic cylinder can also be selected. A clamping seat 10 is installed at the output end of the left linear actuator 9. A clamping groove 12 for clamping the head of the anchor rod 11 is provided at the upper end of the clamping seat 10. The left linear actuator 9 can drive the tail of the anchor rod 11 to enter and exit the inner side of the heating induction coil 4; after the rod part of the anchor rod 11 is inserted into the hole of the channel body 24, by placing the channel body 24 on the backing plate 8 and clamping the head of the anchor rod 11 into the clamping groove 12, the left linear actuator 9 can be used to drive the clamping seat 10 and the anchor rod 11 to move, so that the tail of the anchor rod 11 can enter and exit the inner side of the heating induction coil 4. When the tail of the anchor rod 11 enters the inner side of the heating induction coil 4, the heating induction coil 4 is energized to heat the tail of the anchor rod 11;

[0025] A lower linear actuator 13 is installed at the lower end of the workbench 3. The lower linear actuator 13 is a hydraulic cylinder, and it can also be an electric cylinder or a pneumatic cylinder. The output end of the lower linear actuator 13 extends to the upper end of the workbench 3 and is provided with a lower die holder 14; an upper linear actuator 15 is installed at the upper end of the top plate 7. The upper linear actuator 15 is a hydraulic cylinder, and it can also be an electric cylinder or a pneumatic cylinder. The output end of the upper linear actuator 15 extends to the lower side of the top plate 7 and is provided with an upper die holder 16. The upper die holder 16 is located directly above the lower die holder 14. The lower die holder 14 and the upper die holder 16 cooperate to clamp the rod part of the anchor rod 11; a lower through groove 20 is provided at the upper end of the lower die holder 14, and an upper through groove 21 is provided at the lower end of the upper die holder 16. The cross-sections of the lower through groove 20 and the upper through groove 21 are both semi-circular; by providing the lower through groove 20 and the upper through groove 21, the rod part of the anchor rod 11 can be conveniently restricted in the limiting space formed by the lower through groove 20 and the upper through groove 21. When the lower die holder 14 and the upper die holder 16 clamp the anchor rod 11, the rod part of the anchor rod 11 fits with the lower through groove 20 and the upper through groove 21, and the anchor rod 11 can be stably clamped;

[0026] A right hydraulic cylinder 17 is installed on the right side plate 6. The output end of the right hydraulic cylinder 17 is provided with a riveting head 18. The riveting head 18 can pass through the heating induction coil 4 under the drive of the right hydraulic cylinder 17 and contact the tail of the anchor rod 11.

[0027] To facilitate the support of the clamping seat 10 and avoid the axial pressure of the right hydraulic cylinder 17 on the left linear actuator 9, a fixed seat 19 is fixed on the left side plate 5. An opening for the output end of the left linear actuator 9 to extend out is provided on the fixed seat 19. The output end of the left linear actuator 9 passes through the opening and is connected to the clamping seat 10. During riveting, the output end of the left linear actuator 9 drives the clamping seat 10 to fit with the fixed seat 19. In this way, when the right hydraulic cylinder 17 rivets the anchor rod 11, the anchor rod 11 acts on the clamping seat 10 and the fixed seat 19, ensuring the safety of the left linear actuator 9.

[0028] To improve the safety of the upper linear actuator 15 and the lower linear actuator 13 and avoid radial loads, a lower sliding plate 22 is fixed at the left end of the lower die holder 14, and an upper sliding plate 23 is fixed at the left end of the upper die holder 16. Both the lower sliding plate 22 and the upper sliding plate 23 are slidably connected to the left side plate 5. When the lower die holder 14 and the upper die holder 16 clamp the anchor rod 11 and are subjected to the pressure of the right hydraulic cylinder 17 on the anchor rod 11, the pressure will be transmitted to the left side plate 5 through the lower sliding plate 22 and the upper sliding plate 23. The left side plate 5 bears the pressure of the right hydraulic cylinder 17 on the anchor rod 11, ensuring the safety of the upper linear actuator 15 and the lower linear actuator 13.

[0029] To facilitate the positioning of the groove body 24, when the lower die holder 14 is at the lower dead center, its top end is higher than the top end of the backing plate 8. In this way, the left end of the groove body 24 can abut against the right end face of the lower die holder 14, and the lower die holder 14 positions the groove body 24.

[0030] To enable the lower die holder 14 and the upper die holder 16 to stably and wrap - clamp the anchor rod 11, the lower die holder 14 is slidably connected to the backing plate 8, and the right end face of the upper die holder 16 is flush with the right end face of the lower die holder 14. When the lower die holder 14 and the upper die holder 16 clamp the anchor rod 11, it can avoid leaving gaps between the lower die holder 14 and the backing plate 8, and between the upper die holder 16 and the backing plate 8, which may cause deformation of the heated tail of the anchor rod 11 at the gaps.

[0031] The working principle of this embodiment:

[0032] Manually insert the anchor rod 11 into the hole of the groove body 24, and then place the groove body 24 on the backing plate 8, and make the left end of the groove body 24 abut against the right end of the upper die holder 16 to achieve the positioning of the groove body 24;

[0033] Subsequently, the head of the anchor rod 11 is clamped into the clamping groove 12 to achieve the positioning of the anchor rod 11, as Figure 1 shown;

[0034] Subsequently, the riveting operation is started, as Figure 2 shown. The left linear actuator 9 drives the clamping seat 10 and the anchor rod 11 to move. When the tail of the anchor rod 11 enters the inner side of the heating induction coil 4, the heating induction coil 4 is powered on to heat the tail of the anchor rod 11; after heating is completed, the left linear actuator 9 drives the clamping seat 10 and the anchor rod 11 to reset. The clamping seat 10 moves to the left side position of the lower die holder 14, so that the tail of the anchor rod 11 moves away from the inner side of the heating induction coil 4 and moves into the inner side of the groove body 24, and the heating induction coil 4 is powered off;

[0035] Subsequently, the upper linear actuator 15 drives the upper die holder 16 to descend, and the lower linear actuator 13 drives the lower die holder 14 to ascend, so that the lower die holder 14 and the upper die holder 16 cooperate to clamp the rod part of the anchor rod 11;

[0036] Subsequently, the right hydraulic cylinder 17 drives the riveting head 18 to move to the right. The riveting head 18 passes through the heating induction coil 4 and contacts the tail of the anchor rod 11, as Figure 3 shown, and squeezes the heated part at the right end of the anchor rod 11 to make it deformed, realizing the hot - riveting connection;

[0037] Finally, the right hydraulic cylinder 17 drives the riveting head 18 to move to the left to reset, the upper linear actuator 15 drives the upper die holder 16 to ascend to reset, and the lower linear actuator 13 drives the lower die holder 14 to descend to reset; at this time, the groove body 24 can be moved, and the next position for inserting the anchor rod 11 on the groove body 24 is moved to the clamping seat 10, and the above steps are repeated to realize the riveting of the anchor rod 11 and the groove body 24, and the embedded channel is made.

[0038] The riveting device of this embodiment can achieve automatic heating of the tail of the anchor rod 11, automatic clamping of the anchor rod 11, and hot riveting operations by first inserting the anchor rod 11 into the groove body 24 and then positioning the positions of the anchor rod 11 and the groove body 24. It can avoid safety accidents caused by manual contact with the heated anchor rod 11. At the same time, it can shorten the time-consuming from heating to extrusion of the anchor rod 11, ensure the appropriate temperature during hot riveting of the anchor rod 11, and improve the riveting effect.
