Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a mold for edge banding an inner panel of an automobile door, including a processing table 1 and an inner panel of an automobile door 3. An edge banding mechanism 2 is provided on the processing table 1 for edge banding the inner panel of the automobile door 3. The edge banding mechanism 2 includes: Positioning component 21 is set on processing table 1 and used to position the inner panel 3 of the car door; The folding assembly 22 includes a fixing component 221 disposed on the top of the processing table 1 and used to fix the inner panel 3 of the car door on the positioning assembly 21. The fixing component 221 is provided with an execution component 222 and used to pre-wrap the inner panel 3 of the car door. The pressing assembly 23 is set on the processing table 1 and is used for the final edge wrapping of the inner panel 3 of the automobile door.

[0016] In this implementation scheme, the positioning component 21 precisely positions the inner panel 3 of the car door. Then, the fixing component 221 horizontally clamps the positioned workpiece from all sides. Next, the execution component 222 drives the cutting block to rotate through the cam mechanism to complete the 45° pre-edge wrapping. Finally, the pressure head 233 of the pressing component 23 presses the pre-bent edge into place in one go under the drive of the cylinder. This realizes a fully automated process flow from positioning, clamping, pre-edge wrapping to final edge wrapping, which not only ensures the stability and consistency of the edge wrapping process and improves production efficiency, but also ensures the accuracy and surface quality of the edge wrapping, meeting the high standard manufacturing requirements of the inner panel 3 of the car door.

[0017] Specifically, the fixing component 221 includes a base 2211 fixed to the four ends of the top of the processing table 1. A second cylinder 2212 is installed on the upper end of the base 2211. A mounting seat 2213 is fixed to the output end of the second cylinder 2212. A pressure plate 2214 is fixed on the mounting seat 2213.

[0018] In this embodiment, after the positioning component 21 completes the positioning of the inner panel 3 of the car door, the output end of the second cylinder 2212 extends to drive the mounting base 2213 to drive the pressure plate 2214 to perform a horizontal radial clamping action, thereby simultaneously pressing the edge area of ​​the inner panel 3 of the car door on the positioning component 21 from all sides. This clamping method can avoid the displacement or deformation of the sheet metal caused by unilateral force during the edge wrapping process, and the horizontal clamping method will not affect the vertical edge wrapping operation space.

[0019] Specifically, the execution component 222 includes lugs 2221 fixed to the upper ends of both sides of the pressure plate 2214, a blade block 2222 rotatably mounted between the lugs 2221, a guide frame 2223 fixed to the outer wall of the blade block 2222, a guide groove 2224 opened inside the guide frame 2223, a third cylinder 2225 mounted at the bottom of the mounting base 2213, a connecting block 2226 fixed to the output end of the third cylinder 2225, a cam 2227 rotatably mounted inside the connecting block 2226, and the cam 2227 is located inside the guide groove 2224.

[0020] In this embodiment, after the fixing component 221 fixes the inner panel 3 of the car door on the positioning component 21, the output end of the third cylinder 2225 extends out, pushing the connecting block 2226 and the cam 2227 to move upward. Since the cam 2227 is embedded in the guide groove 2224 of the guide frame 2223, the curved surface of the cam 2227 and the guide groove 2224 generate relative movement, thereby forcing the blade block 2222 to rotate around the rotation center of the shaft lug 2221, and performing a flanging operation on the vertical edge of the inner panel 3 of the car door, precisely bending it to about 45°, in preparation for the final edge binding.

[0021] Specifically, the positioning component 21 includes a positioning seat 211 fixed to the top of the processing table 1, a slide plate 212 is longitudinally slidably installed inside the positioning seat 211, a positioning block 213 is fixed to the front end of the slide plate 212, and a first cylinder 214 is installed inside the positioning seat 211 to drive the slide plate 212 to move.

[0022] In this embodiment, after the inner panel 3 of the car door is placed on the upper end of the positioning seat 211, the first cylinder 214 drives the sliding plate 212 to move the positioning block 213 vertically downward, thereby positioning and fixing the lower end of the inner panel 3 of the car door.

[0023] Specifically, the pressing assembly 23 includes a frame 231 fixed on the top of the processing table 1, a fourth cylinder 232 is mounted on the upper end of the frame 231, and a pressure head 233 is fixed to the output end of the fourth cylinder 232.

[0024] In this embodiment, after the pre-edge binding process is completed by the folding assembly 22, the output end of the fourth cylinder 232 extends downward and drives the pressure head 233 to perform vertical pressing on the edge of the pre-bent car door inner panel 3.

[0025] Specifically, the shape of the lower working surface of the pressure head 233 matches the edging contour of the inner panel 3 of the car door, and the pressure head 233 is fixed to the output end of the fourth cylinder 232 by bolts.

[0026] In this embodiment, the pressure head 233 adopts a surface design that perfectly matches the final edge contour of the inner panel 3 of the car door through its lower working surface. When the fourth cylinder 232 drives the pressure head 233 to perform the pressing operation, the surface can completely cover the edge of the inner panel 3 that is pre-bent to 45°. By uniformly applying pressure, the edge of the inner panel 3 of the car door undergoes plastic deformation along the predetermined contour.

[0027] The working principle and usage process of this utility model are as follows: First, the operator or robot arm places the inner panel 3 of the car door on the upper end of the positioning seat 211 of the positioning component 21. The first cylinder 214 drives the slide plate 212 to move the positioning block 213 downward along the longitudinal direction to complete the initial positioning and fixing of the workpiece. Subsequently, the fixed components 221 distributed at the four ends of the top of the processing table 1 begin to work. The output end of the second cylinder 2212 extends out to drive the mounting base 2213 to drive the pressure plate 2214 to perform a horizontal radial clamping action, pressing the edge area of ​​the inner panel 3 of the car door from all sides at the same time, ensuring that the workpiece remains stable during the processing. Next, the actuator 222 is activated, and the output end of the third cylinder 2225 extends to push the connecting block 2226 and the cam 2227 to move upward. Through the relative movement between the curved surface of the cam 2227 and the guide groove 2224 inside the guide bracket 2223, the cutter block 2222 is forced to rotate around the rotation center of the shaft lug 2221 to perform a precise 45° pre-flanging operation on the vertical edge of the inner edge of the car door panel 3. Finally, the pressing assembly 23 starts working, the output end of the fourth cylinder 232 extends downward, driving the pressure head 233, whose lower working surface is perfectly matched with the edge-binding contour, to perform vertical pressing on the pre-bent edge. By uniformly applying pressure, the edge of the workpiece undergoes plastic deformation along the predetermined contour, and the final edge-binding process is completed in one go.
