Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1:

[0020] Please see Figure 1-5 This utility model provides a technical solution: a wheel hub inner liner trimming device, including a base 100 and a plurality of inner liner metal plates 101, the inner liner metal plates 101 being provided with a plurality of annular indentations 102 and linear indentations 103; a support frame 104 is installed on the base 100, a hydraulic cylinder 105 is installed on the support frame 104, a pressure plate 106 is installed on the telescopic end of the hydraulic cylinder 105, an mounting frame 200 and an annular baffle 300 are installed on the base 100, a shearing structure is connected to the mounting frame 200, the shearing structure is used to shear the inner liner metal plates 101 along the annular indentations 102 and linear indentations 103, and a material-pushing structure is connected to the annular baffle 300, the material-pushing structure is used to push the scrap material away from the base 100.

[0021] Furthermore, the shearing structure includes an annular cutter 201, which is mounted on the mounting bracket 200. The annular cutter 201 has the same shape as the annular indentation 102 on the inner liner metal plate 101. Several straight cutters 202 are evenly installed on the annular cutter 201, and the straight cutters 202 correspond to the straight indentations 103. Several inner liner metal plates 101 can be stacked on top of the annular cutter 201. The hydraulic cylinder 105 is activated to drive the pressure plate 106 to press the inner liner metal plates 101 downward. When the inner liner metal plates 101 are pressed down, the annular cutter 201 will cut along the position of the annular indentation 102, while the straight cutters 202 will cut along the position of the straight indentation 103. Finally, the inner liner metal plate 101 retains the middle part due to the pattern formed by the annular indentation 102 and the straight indentation 103.

[0022] Furthermore, several unloading plates 203 are evenly installed on the annular cutter 201 and the mounting bracket 200. The unloading plates 203 are inclined. When the inner metal plate 101 is cut, several scraps will be formed around it. The unloading plates 203 can be designed at a 55-degree angle. The scraps will slide down the inclined surface of the unloading plates 203 into the annular baffle 300.

[0023] Furthermore, both the mounting bracket 200 and the base 100 have a discharge hole 204 inside, which corresponds to the inner metal plate 101. The base 100 has a discharge port 205 inside, which is connected to the discharge hole 204. The cut inner metal plate 101 will fall into the discharge hole 204 and then slide out from the discharge port 205, thus achieving discharge.

[0024] Example 2:

[0025] like Figure 1-5 To facilitate the cleaning of the cut waste, a material-pushing structure is arranged. This structure includes a movable rotating ring 301, which is rotatably mounted on an annular baffle 300. A geared ring 302 is installed on one side of the movable rotating ring 301, and a reduction motor 303 is installed on one side of the base 100. A linkage gear 304 is installed at the output end of the reduction motor 303, meshing with the geared ring 302. Several push plates 305 are evenly and detachably mounted on the movable rotating ring 301, and the push plates 305 are located on the mounting bracket 200. Between the annular baffle 300 and the base 100, a waste port 306 is provided on the base 100. The waste port 306 is located inside the annular baffle 300. The gear motor 303 is turned on to drive the linkage gear 304 to rotate. The rotating linkage gear 304 can drive the movable rotating ring 301 to rotate by meshing with the gear ring 302. When the movable rotating ring 301 rotates, it will drive several push plates 305 to push the scrap material inside the annular baffle 300 and push the scrap material to the waste port 306 to slide out. A receiving frame can be set below the waste port 306 for receiving and recycling.

[0026] Furthermore, a bearing 307 is fixedly sleeved on the annular baffle 300. The outer ring of the bearing 307 is mounted on the movable rotating ring 301, and the inner ring of the bearing 307 is mounted on the annular baffle 300. When the movable rotating ring 301 rotates, it will drive the outer ring of the bearing 307 to rotate, causing the outer ring of the bearing 307 to drive the internal balls to move. The bearing 307 makes the rotation of the movable rotating ring 301 smoother.

[0027] Furthermore, the push plate 305 has two positioning holes 308 inside, and positioning rods 309 are movably installed in both positioning holes 308. Both positioning rods 309 are installed on one side of the movable rotating ring 301. The position of the push plate 305 can be positioned by using the positioning holes 308 and the positioning rods 309.

[0028] Furthermore, two mounting bolts 310 are movably mounted on the push plate 305. Several screw holes 311 are opened inside the movable rotating ring 301. The two mounting bolts 310 are respectively threaded into the corresponding screw holes 311. Rotating the mounting bolts 310 and unscrewing them from the screw holes 311 can release the position restriction on the push plate 305. Screwing the mounting bolts 310 back into the screw holes 311 can fix the position of the push plate 305.

[0029] The working principle is as follows:

[0030] The annular indentation 102 and the straight indentation 103 on the inner metal plate 101 are the initial indentations. Rollers with preset patterns or grooves are used to press the metal plate, creating indentations on the material surface that match the shape of the cutting blade in the subsequent extrusion and trimming device. This provides a positioning reference or guide trajectory for the subsequent extrusion and trimming process. During trimming, several inner metal plates 101 can be stacked on top of the annular cutter 201, aligning the annular cutter 201 with the annular indentation 102, while simultaneously aligning the straight cutter 202 with the straight indentation 103. Then, the hydraulic cylinder 105 is activated, causing the pressure plate 106 to press the inner metal plate 101 downwards. When the inner metal plate 101 is pressed down, it is subjected to annular... The shearing action of the annular cutter 201 and the straight cutter 202 involves the annular cutter 201 cutting along the position of the annular indentation 102, while the straight cutter 202 cutting along the position of the straight indentation 103. Ultimately, the inner liner metal plate 101 retains its middle portion due to the pattern formed by the annular indentation 102 and the straight indentation 103. The cut inner liner metal plate 101 falls into the discharge hole 204 and then slides out from the discharge port 205, thus completing the unloading. Several scrap pieces are formed around the inner liner metal plate 101. The unloading plate 203 can be designed with a 55-degree angle so that the scrap pieces slide down the slope of the unloading plate 203 into the annular baffle 300.

[0031] The geared motor 303 is turned on to drive the linkage gear 304 to rotate. The rotating linkage gear 304, through meshing with the gear ring 302, drives the movable rotating ring 301 to rotate. The continuously rotating movable rotating ring 301 drives several push plates 305 to perform circumferential motion between the annular baffle 300 and the mounting bracket 200. At the same time, it agitates the scrap material inside the annular baffle 300, pushing the scrap material towards the waste outlet 306. Finally, the scrap material can slide out from the waste outlet 306. A receiving frame can be set below the waste outlet 306. To facilitate the recycling of scrap materials, when the push plate 305 wears or deforms over time, the mounting bolt 310 can be rotated and unscrewed from the screw hole 311 to release the position restriction of the push plate 305. Then, the push plate 305 can be pulled off the positioning rod 309 to complete the disassembly. When installing a new push plate 305, it can be fitted onto the positioning rod 309 through the positioning hole 308, and then the mounting bolt 310 can be screwed back into the screw hole 311 to fix the position of the push plate 305.
