[0001] The utility model relates to the field of wheel rim processing, in particular to a wheel rim spinning width adjustment die. Background Art

[0002] The rim refers to the outer part of the wheel on a vehicle, usually made of metal. It is an important part of the wheel, carrying the weight of the vehicle and providing support and balance for driving. The rim usually consists of a rim and spokes. The rim is the outer annular part of the rim, used to mount the tire. The spoke is the support rod connecting the rim and the axle, which plays a role in supporting and transmitting force. The design and material selection of the rim have an important impact on the performance and safety of the vehicle, so the use environment and needs of the vehicle need to be considered when manufacturing and selecting the rim. The rim is usually made of high-strength metal materials such as aluminum alloy or steel.

[0003] During the production process of the rim, it is necessary to perform spinning to form the outer wheel flange. During spinning, the rim needs to be placed on a spinning mold for processing. In the prior art, the mold adopts an integral design, and different molds are selected according to the different widths of the rim. That is, when the specifications of the rim change, the matching mold needs to be replaced synchronously, resulting in the following problems: 1. The mold needs to be replaced frequently when spinning different rims, which affects production efficiency and increases the workload of employees; 2. The overall mold is large and overweight, which can easily cause safety hazards when on-site staff carry and replace it. Summary of the invention

[0024] See also Figure 1-3 A rim spinning width adjustment mold shown in the figure includes a spinning main shaft 1, a spinning left mold 2 is provided on one side of the spinning main shaft 1, a fixed insert 3 is provided in the spinning left mold 2, an adjustment insert 4 is provided at one end of the fixed insert 3, a connecting ring 3a is provided at one end of the fixed insert 3, and a connecting block 4a is provided at one end of the adjusting insert 4. A spinning right mold 5 is provided on the side of the spinning left mold 2 away from the spinning main shaft 1, a driven shaft 6 is provided on the side of the spinning right mold 5 away from the spinning left mold 2, a pushing cylinder 7 is provided on one side of the driven shaft 6, the hydraulic rod of the pushing cylinder 7 is connected to the driven shaft 6 and provides thrust. When the mold is closed, the pushing cylinder 7 slowly pushes the driven shaft 6 toward the main rotating shaft 1, so that the spinning right mold 5 and the spinning left mold 2 are closed.

[0025] The spinning main shaft 1 is fixedly connected to the spinning left mold 2. A hollow hole is provided in the spinning left mold 2. The fixed insert 3 is fixed in the hollow hole. When in use, one end of the spinning main shaft 1 is connected to the motor shaft and is driven by the motor to rotate, and the spinning main shaft 1 drives the spinning left mold 2 to rotate. When the spinning right mold 5 and the spinning left mold 2 are closed, the driven shaft 6 follows the spinning main shaft 1 and rotates drivenly through the drive of the motor, thereby making the spinning left mold 2 and the spinning right mold 5 rotate synchronously. At this time, spinning forming is carried out, and the spinning main shaft 1 and the driven shaft 6 are both rotating shafts.

[0026] See also Figure 3The connecting ring 3a is in the shape of a hollow cylindrical ring, the connecting block 4a is in the shape of a cylindrical protrusion, the connecting block 4a is inserted in the connecting ring 3a, the adjusting insert 4 is connected with the fixed insert 3 through the connecting block 4a, the fixed insert 3 is fixed in the left spinning mold 2, and the adjusting insert 4 has different lengths to match the rims 9 of different specifications. For example, when the width of the rim 9 is longer, the adjusting insert 4 with a longer length is selected to connect with the fixed insert 3 to increase the distance between the left spinning mold 2 and the right spinning mold 5, so that the rim 9 can be properly mounted on the left spinning mold 2 and the right spinning mold 5, and the edge of the rim 9 can overlap with the limit block 8 to form a limit, so that the spinning process is smooth.

[0027] The right spinning die 5 is fixedly connected to the driven shaft 6, and the hydraulic rod of the push cylinder 7 is fixedly connected to the driven shaft 6. The driven shaft 6 plays a driven auxiliary rotation role. When the left spinning die 2 and the right spinning die 5 are closed, driven by the spinning spindle 1, the right spinning die 5 and the driven shaft 6 rotate synchronously, and the spinning tool 10 contacts the outer surface of the rim 9 for extrusion molding.

[0028] The surface structure of the left spinning mold 2 and the right spinning mold 5 is the same. Limit blocks 8 are provided at the edges of the left spinning mold 2 and the right spinning mold 5. The limit blocks 8 are used to overlap with the edge of the rim 9 and provide stable support.

[0029] The specific working principle is: during production, the model of the required adjusting insert 4 is determined according to the model of the product (rim 9) to match it, and the left and right molds are fixed to the rotating main shaft 1 and the driven shaft 6 respectively. After fixing, the corresponding adjusting insert 4 is selected according to the product width and installed on the left spinning mold 2. After the fixed insert 3 is connected with the adjusting insert 4, the product is inserted into the left side, the program is started, and the pushing cylinder 7 pushes the right spinning mold 5 to the adjusting insert 4 to start processing.
