Description

Technical Field

[0001] The utility model belongs to the technical field of wheel spinning processing, and particularly relates to a wheel spinning die cushion device. Background Art

[0002] The spinning process is to fix a flat or hollow blank on the die of a spinning machine. While the blank rotates with the main shaft of the machine tool, a spinning wheel or a driving bar is used to apply pressure to the blank, causing local plastic deformation of the blank. And finally, the local deformation expands to the whole blank under the transverse or longitudinal feeding movement of the core die, so as to complete the spinning process and obtain a product with the required shape.

[0003] The performance of the product after spinning is significantly improved. After spinning, the organizational structure and mechanical properties of the material both change. The grain size is fine and has a fibrous characteristic. The tensile strength, yield strength and hardness are all significantly improved. Spinning can make the product reach a high dimensional accuracy and surface finish. During the spinning process, the roller not only has a rolling effect on the spun metal blank, but also has a flattening effect, so the surface finish of the product is high.

[0004] With the increasing demand for wheel products in the market, most of the front shapes of the wheels are the same, and only the rim widths are different. When producing, multiple sets of new dies need to be developed to meet the needs, which leads to an increase in die development costs and a decrease in production efficiency.

The inner end of the transverse part 110 of the pressing block is connected to the top end of the vertical part 120 of the pressing block to form a bent structure; a pressing block bolt 130 is arranged inside the vertical part 210 of the pressing block, and the lower end of the pressing block bolt 130 extends below the vertical part 120 of the pressing block; the cushion block 2 includes an annular transverse part 210 of the cushion block and an annular vertical part 220 of the cushion block. The outer end of the transverse part 210 of the cushion block is connected to the top end of the vertical part 220 of the cushion block to form a bent structure; the cushion block 2 is sleeved on the vertical part 120 of the pressing block, and both the transverse part 110 of the pressing block and the vertical part 120 of the pressing block are in contact with the transverse part 210 of the cushion block; a cushion block bolt 230 is arranged inside the transverse part 210 of the cushion block, and the lower end of the cushion block bolt 230 extends below the transverse part 210 of the cushion block.

[0028] For the wheel spinning die pad device of this embodiment, during use, the spinning upper die 4 is arranged above the pad device, and the spinning lower die 5 is arranged below the pad device. The wheel blank 6 is arranged below the spinning upper die 4 and above the pressing block 1 of the spinning lower die 5 and the pad device. The top surface of the transverse part 110 of the pressing block is in contact and matches with the D surface 620 of the wheel, that is, the pressing block 1 forms a D surface pressing block. The A surface 610 of the wheel is in contact with the outer part of the bottom surface of the spinning upper die 4. The spoke position of the wheel blank 6 is pressed by the spinning upper die 4 and the pressing block 1, and the rim position leans against the pad 2 to ensure the positioning accuracy. According to the actual needs, the spinning lower die 5 can be connected to the pad of the pad device through the pad bolt 230. A connecting block 3 can be arranged between the spinning lower die 5 and the pad device. The connecting block 3 can be connected to the pressing block 1 of the pad device through the pressing block bolt 130. The wheel blank 6 is pressed by the rising and falling of the spinning upper die 4, and the pressing block 1 is used to ensure the accuracy of the blank placement position. According to different wheel types, the shapes of the spinning upper die 4, the pressing block 1 and the pad 2 will be different. In practical applications, for the same wheel type and different rim lengths, the shapes of the A surface 610 and the D surface 620 of the wheel are the same. The mold can be shared by replacing the pads 2 with different vertical heights, thereby reducing the mold development cost.

[0029] Among them, the inner side direction refers to the side close to the vertical central axis of the spinning upper die 4 and the spinning lower die 5, and the outer side direction refers to the side far from the vertical central axis of the spinning upper die 4 and the spinning lower die 5.

[0030] Please refer to Figure 1 , specifically, the top surface of the transverse part 110 of the pressing block slopes upward from the inside to the outside to match the shape of the D surface 620 of the wheel.

The bottom surface of the transverse part 110 of the pressing block and the outer side surface of the vertical part 120 of the pressing block are respectively in contact with the top surface and the inner side surface of the transverse part 210 of the pad.

[0032] Specifically, the outer side surface of the vertical part 220 of the pad slopes outward from top to bottom to match the outer side surface of the spinning lower die 5 that slopes outward from top to bottom, so as to match the inclined spinning formed rim shaping surface 650 on the blank 640 after spinning.

[0034] Specifically, the bottom surface of the pad block transverse portion 210 is perpendicular to the inner side surface of the pad block vertical portion 220 , so as to facilitate matching connection with the top of the spinning lower die 5 .

[0035] Specifically, the bottom surface of the pressing block 1 is arranged below the bottom surface of the cushion block 2, so that the pressing block 1 is connected to the connecting block 3 below it, and the bottom surface of the pressing block 1 is arranged below the top surface of the spinning lower die 5. The bottom of the pressing block vertical part 120 is connected with an annular connecting block 3 through the pressing block bolt 130, the top surface of the connecting block 3 is in contact with the bottom surface of the pressing block vertical part 120, and the outer side surface is arranged below the inner side surface of the cushion block vertical part 220; the upward extension line of the outer side surface of the connecting block 3 is flush with the inner side surface of the cushion block vertical part 220; so that the outer side surface and the top surface of the connecting block 3 can respectively press against the inner side surface of the spinning lower die 5 and the bottom surface of the pressing block 1, thereby improving the firmness of the connecting structure of the connecting block 3.

[0036] For more details, please refer to Figure 2 and Figure 3 The pressure block 1 and the cushion block are both set to be circular.
