Detailed Implementation

[0019] Example 1

[0020] like Figure 1 The heat shrink tubing shaping fixture shown includes a base plate 1, with support rods 2 connected to opposite sides of the base plate 1, and a crossbeam 3 connecting the support rods 2. A pressing device 4 is connected to the crossbeam 3. A fixture 5 is connected to the top surface of the base plate 1 and is placed below the pressing device 4. The workpiece to be pressed is placed on the fixture 5. A support platform 6 is located adjacent to the fixture 5, connected to the top surface of the base plate 1, and is positioned in a limiting groove 51 (see...). Figure 4 The support platform 6 has an opening on one side, and the top surface of the support platform 6 and the bottom surface of the limiting groove 51 are set to the same horizontal plane.

[0021] like Figures 2-3The heat shrink tubing shaping fixture shown has a support rod 2 with a countersunk through hole 21. A fastener 22 passes through the countersunk through hole 21, and the fastener 22 connects and fixes the crossbeam 3 and the support rod 2. The countersunk through hole 21 is an oblong hole, and its long axis is vertically arranged. The pressing device 4 includes a quick-pressing mechanism 41 and a pressing block 42. The quick-pressing mechanism 41 is connected to the crossbeam 3, and the quick-pressing mechanism 41 and the pressing block 42 are driven together. The crossbeam 3 is connected to a guide post 43, which is vertically arranged. The pressing block 42 and the guide post 43 are slidably connected, and the quick-pressing mechanism 41 drives the pressing block 42 to slide along the guide post 43. The quick-pressing mechanism 41 includes a support 411, a pressing handle 412, and a pressing rod 413. The pressing rod 413 is vertically arranged and slidably connected to a through hole at the lower end of the support 411. The upper ends of the pressure handle 412 and the support 411 are hinged together. The pressure handle 412 is connected to the pressure rod 413 via the connecting arm 414. The pressure handle 412 is V-shaped, with one end hinged to the support 411, and the pressure handle 412 is positioned as a grip away from the support 411. When the pressure block 42 presses the workpiece against the top surface of the tooling fixture 5, the hinged end of the pressure handle 412, the connecting arm 414, and the pressure rod 413 are arranged in a straight line. The lower end of the pressure rod 413 is provided with an external thread, and a clamping nut 415 and a locking nut 416 are threadedly connected to the lower end of the pressure rod 413. The lower end of the pressure rod 413 is threadedly connected to the pressure block 42, the clamping nut 415 is locked to the top surface of the pressure block 42, and the locking nut 416 locks the clamping nut 415 to the top surface of the pressure block 42.

[0022] like Figure 4 The heat shrink tubing shaping fixture shown has a limiting groove 51 on its top surface. The limiting groove 51 is rectangular and has an opening on one short side. A notch 52 is provided on the side wall of the fixture 5, located on the side of the limiting groove 51 away from the opening of the limiting groove 51. There are two or more limiting grooves 51, which are arranged parallel to each other on the top surface of the fixture 5.

[0023] During production, heat shrink tubing is fitted over the outside of the product, and then the product is placed in a tunnel furnace for heating, causing the heat shrink tubing to shrink. After the product has passed through the tunnel furnace, the heat shrink tubing has shrunk and covered the product surface. The product is then placed in the limiting groove 51 of the tooling fixture 5, with one end of the product extending out of the limiting groove 51 resting on the top surface of the support platform 6. Then, the pressure handle 412 is turned downwards, pushing the pressure rod 413 towards the tooling fixture 5 via the connecting arm 414. The pressure rod 413 then pushes the pressure block 42 to press against the product surface. When the heat shrink tubing on the product surface cools, the pressure handle 412 is turned upwards, pushing the pressure rod 413 away from the tooling fixture 5 via the connecting arm 414, causing the pressure block 42 to detach from the product surface. Finally, the product is removed from the limiting groove 51, and the shaping process is complete.
