[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0023] like Figure 1-5 As shown, the utility model provides a steering wheel shell bending mechanism, including a bearing plate 1 and an extrusion mechanism 7, a mounting plate 2 and a plurality of fixing rods 8 are fixedly installed on the top of the bearing plate 1, a mold 3 is fixedly installed on the top of the mounting plate 2, and a fixing mechanism 4 is provided, the inner wall of the mold 3 is provided with a limiting groove 300, the inner wall of the limiting groove 300 is provided with two sliding grooves 301, a pushing assembly 5 is provided in the limiting groove 300, and the pushing assembly 5 includes a pushing plate 501, two guide rods 502 and two compression springs 503, the pushing plate When 501 is subjected to pressure, it drives the two guide rods 502 to slide with the two slide grooves 301 and squeeze the two compression springs 503. The fixing mechanism 4 includes two cylinders 1 402, two squeezing plates 404, two cylinders 2 405 and two squeezing blocks 407. The two cylinders 1 402 respectively drive the two squeezing plates 404 to move, and the two cylinders 2 405 respectively drive the two squeezing blocks 407 to move. A support platform 800 is fixedly installed on the top of the several fixing rods 8, and the squeezing mechanism 7 is arranged on the top of the support platform 800.

[0024] The staff first places the steering wheel housing in the mold 3. During the placement of the steering wheel housing, the steering wheel housing can squeeze the push plate 501. When squeezed, the push plate 501 slides in the limiting groove 300. When the push plate 501 moves, it can not only drive the two guide rods 502 to slide in the corresponding sliding grooves 301, but also cooperate with the limiting grooves 300 to squeeze the two compression springs 503.

[0025] Then, the two cylinders 1 402 and the two cylinders 2 405 are started. After the two cylinders 1 402 are operated, their output ends respectively push the two extrusion plates 404 to move, and the two extrusion plates 404 move a certain distance to initially fix the steering wheel shell. After the two cylinders 2 405 are operated, their output ends respectively push the two connecting members 406 to move horizontally. When the two connecting members 406 move, they respectively drive the two extrusion blocks 407 to move horizontally, so that the two extrusion blocks 407 further limit the steering wheel shell, thereby improving the fixing effect of the steering wheel shell before bending, thereby reducing the effect of the steering wheel shell being affected by the deviation during bending, and improving applicability.

[0026] After the steering wheel shell is bent, the two cylinders 1 402 and the two cylinders 2 405 are closed, and the steering wheel shell is no longer fixed. At this time, the two compression springs 503 release the pressure, thereby driving the push plate 501 to move in the opposite direction and push the steering wheel shell, so that the steering wheel shell can be separated from the mold 3 by a certain distance after the bending is completed, which is convenient for the staff to take out, simplifies the operation difficulty, and further improves the applicability.

[0027] like Figure 3-4 As shown, in one embodiment, the pusher assembly 5 also includes two limit blocks 504, the two guide rods 502 are respectively slidably matched with the two slide grooves 301, the two limit blocks 504 are respectively fixedly connected to one end of the two guide rods 502, and are respectively slidably matched with the two slide grooves 301, the pusher plate 501 is fixedly connected to the other end of the two guide rods 502, and the two compression springs 503 are respectively mounted on the two guide rods 502, and the two ends are respectively connected to the pusher plate 501 and the limit groove 300.

[0028] The two limiting blocks 504 can limit the push plate 501 through the two sliding grooves 301 and the two guide rods 502, and will not cause the push plate 501 to escape from the limiting grooves 300, thereby rationalizing the structure.

[0029] like Figure 2As shown, in one embodiment, the fixing mechanism 4 also includes two locking plates 401 and two L-shaped plates 403, the two locking plates 401 are fixedly mounted on the top of the mounting plate 2, the two cylinder ones 402 are fixedly mounted on the two locking plates 401, the two L-shaped plates 403 are fixedly connected to the output ends of the two cylinder ones 402, and the two extrusion plates 404 are fixedly connected to the tops of the two L-shaped plates 403. The fixing mechanism 4 also includes two connecting members 406, the two cylinder twos 405 are fixedly connected to the mounting plate 2, the two connecting members 406 are fixedly connected to the output ends of the two cylinder twos 405, and the two ends of the two extrusion blocks 407 are fixedly connected to the two connecting members 406.

[0030] The two locking plates 401 are used to fix the two cylinders 402 to improve the structural stability. At the same time, the connecting piece 406 is used to connect the cylinder 2 405 and the extrusion block 407 to prevent the cylinder 2 405 from being pushed out insufficiently.

[0031] like Figure 1 and Figure 5 As shown, in one embodiment, a support rod 6 is fixedly installed on the top of the supporting plate 1, and a detector 600 is fixedly sleeved on one end of the support rod 6. The extrusion mechanism 7 includes an electric cylinder 705, a connecting plate 706 and an extrusion assembly 707. The connecting plate 706 is fixedly connected to the output end of the electric cylinder 705, and the extrusion assembly 707 is fixedly connected to the connecting plate 706. The extrusion mechanism 7 also includes a fixed frame 700, a guide rail 701, a motor 702, a screw 703 and a support frame 704. The fixed frame 700 is fixedly installed on the top of the supporting platform 800, the guide rail 701 is fixedly connected to one end of the fixed frame 700, the motor 702 is fixedly installed on the top of the guide rail 701, and the output end is fixedly connected to the screw 703, the screw 703 is rotatably connected to the guide rail 701, the support frame 704 is threadedly sleeved on the screw 703, and slides with the guide rail 701, and the electric cylinder 705 is fixedly installed at one end of the support frame 704.

[0032] After the steering wheel housing is fixed, the motor 702 and the electric cylinder 705 are started in sequence. When the output end of the motor 702 rotates, the screw 703 is driven to rotate. When the screw 703 rotates, it is threadedly engaged with the support frame 704 and drives the support frame 704 to move vertically downward under the limit of the guide rail 701. When the support frame 704 moves, it drives the electric cylinder 705 to move. After the electric cylinder 705 moves to the specified position, the motor 702 is turned off. After the output end of the electric cylinder 705 is operated, it pushes the extrusion assembly 707 to move vertically downward through the connecting plate 706, so that the extrusion assembly 707 cooperates with the mold 3, and then the steering wheel housing is extruded and bent. The detector 600 can detect whether there are parts in the mold 3 before the extrusion mechanism 7 operates, so as to avoid invalid processing and improve applicability.

[0033] The detector 600 and the extrusion assembly 707 are both prior art and will not be explained here.

[0034] The following is a detailed description of the working principle of the steering wheel housing bending mechanism:

[0035] The staff first places the steering wheel housing in the mold 3. During the placement of the steering wheel housing, the steering wheel housing can squeeze the push plate 501. When squeezed, the push plate 501 slides in the limiting groove 300. When the push plate 501 moves, it can not only drive the two guide rods 502 to slide in the corresponding sliding grooves 301, but also cooperate with the limiting grooves 300 to squeeze the two compression springs 503.

[0036] Then, the two cylinders 1 402 and the two cylinders 2 405 are started. After the two cylinders 1 402 are operated, their output ends respectively push the two L-shaped plates 403 to move. When the two L-shaped plates 403 move, they drive the two extrusion plates 404 to move. After the two extrusion plates 404 move a certain distance, they preliminarily fix the steering wheel shell. After the two cylinders 2 405 are operated, their output ends respectively push the two connecting members 406 to move horizontally. When the two connecting members 406 move, they drive the two extrusion blocks 407 to move horizontally, so that the two extrusion blocks 407 further limit the steering wheel shell, thereby improving the fixing effect of the steering wheel shell before bending, thereby reducing the effect of the steering wheel shell being affected by the deviation during bending, and improving applicability.

[0037] After the steering wheel shell is fixed, the motor 702 and the electric cylinder 705 are started in sequence. When the output end of the motor 702 rotates, the screw 703 is driven to rotate. When the screw 703 rotates, it is engaged with the thread of the support frame 704 and drives the support frame 704 to move vertically downward under the limit of the guide rail 701. When the support frame 704 moves, it drives the electric cylinder 705 to move. After the electric cylinder 705 moves to the specified position, the motor 702 is turned off. After the output end of the electric cylinder 705 is operated, the extrusion assembly 707 is pushed vertically downward through the connecting plate 706, so that the extrusion assembly 707 cooperates with the mold 3, thereby extruding and bending the steering wheel shell. After the steering wheel shell is bent, the two cylinders 1 402 and the two cylinders 2 405 are turned off, and the steering wheel shell is no longer fixed. At this time, the two compression springs 503 release the pressure, thereby driving the push plate 501 to move in the opposite direction and push the steering wheel shell, so that the steering wheel shell can be separated from the mold 3 a certain distance after the bending is completed, which is convenient for the staff to take out, simplifies the operation difficulty, and further improves the applicability.

[0038] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
