Description

A wheel spoke wind hole punching device

Technical Field

The utility model relates to the technical field of wheel spoke processing, in particular to a wheel spoke air hole punching device.

Background Art

Spokes refer to the metal brackets that connect the hub and rim of a wheel. The main function of the spokes is to support the rim of the wheel so that it can bear the weight and impact of the vehicle when it is driving, and to enable the wheel to rotate through the connection with the hub. The spokes need to be punched with air holes on the surface during production. The function of the spoke air holes is to dissipate heat through ventilation to prevent the wheel from overheating and increase the service life and performance stability of the wheel. These air holes can also help expel moisture and impurities from the inside of the tire to keep the tire in good condition. In addition, the spoke air holes can also reduce the weight of the spokes and improve the weight balance and rotation performance of the entire wheel.

When processing the spokes, holes are formed by punching with a punch. Burrs will appear on the hole walls after the air hole punching process. The burrs will form an uneven surface on the hole walls of the spokes, which is likely to cause stress concentration and reduce the strength and durability of the spokes. Therefore, it is necessary to deburr the hole walls after the spoke holes are processed. After the air hole punching process is completed, the spokes need to be transferred to another processing step for deburring. The increase in the need for additional handling steps will extend the overall production time and extend the spoke production cycle. During the handling process, the spoke parts are easily contacted with other objects, such as other processed parts, equipment or tools, and the spoke parts are easily subject to collision and friction, resulting in a decrease in part quality.

This embodiment mainly describes a wheel spoke air hole punching device, which is specifically as follows:

As shown in Fig. 1-4, a spoke wind hole punching device comprises a support platform 1, a support frame 2 is fixedly installed on the left side of the upper end of the support platform 1, and the support frame 2 is arranged in an L shape. A pushing mechanism 3 is arranged on the upper end of the support frame 2, and a driving motor 4 is fixedly installed on the lower part of the pushing mechanism 3, and a driving shaft 5 is fixedly installed on the output end of the driving motor 4, and a first positioning screw 6 is movably inserted and connected at the lower end of the driving shaft 5, and a grinding head 7 is fixedly installed at the lower end of the first positioning screw 6, and a second positioning screw 8 is fixedly installed at the lower end of the grinding head 7. By providing the first positioning screw 6 and the second positioning screw 8, the grinding head 7 that is severely worn can be replaced by rotating the first positioning screw 6 and the second positioning screw 8, and the lower part of the second positioning screw 8 is threadedly connected to a support column 9, and a punch 10 is fixedly installed on the lower end of the support column 9, and the punch 10 is made of hard material. The punch 10 is quickly pressed down to apply an impact force to the spoke body 14, and the spoke body 14 is penetrated to form a punch. The wind hole, the upper end of the support platform 1 is movably connected with a rotating shaft 11, and the lower end of the rotating shaft 11 is fixedly installed with a servo motor 12. The rotating shaft 11 is driven to rotate by the servo motor 12, thereby driving the placement mold 13 to rotate and driving the spoke body 14 to rotate for position adjustment, so that the punch 10 can process multiple wind holes on the spoke body 14. The upper end of the rotating shaft 11 is fixedly installed with a placement mold 13, and the spoke body 14 is placed on the placement mold 13. A middle hole 15 is opened in the middle of the upper end of the spoke body 14, and four through grooves 16 are opened at the upper end of the placement mold 13. The diameter of the punch 10 is the same as the diameter of the grinding head 7. The burrs in the wind hole are removed when the grinding head 7 reciprocates up and down. The driving shaft 5 is driven to rotate by the driving motor 4, so that the burrs in the wind hole are further effectively removed when the grinding head 7 rotates. The up and down reciprocating motion can make the grinding head 7 fully contact a larger surface area and completely remove the burrs from the hole wall. At the same time, the rotational motion can ensure that the grinding head 7 applies force evenly on the hole wall, thereby increasing the thoroughness of deburring. In general, the synchronous up and down reciprocating motion and rotation of the grinding head 7 can bring about a better deburring effect on the hole wall of the spoke punching hole, thereby ensuring the quality and appearance of the hole wall. By providing a punch 10 and a grinding head 7, and the punch 10 is located below the grinding head 7, the hole wall can be deburred immediately after the punching process of the spoke body 14, without the need to transport the spoke body 14 to another processing step for deburring. The reduced transport process simplifies the production process of the spoke, shortens the overall production time, and improves the spoke production cycle. At the same time, there is no need to transport the spoke, thereby preventing the possibility of collision between the spoke and other objects, thereby ensuring the product quality of the spoke parts.

A support rod 17 is fixedly installed on both sides of the upper end of the support platform 1. The upper end of the support rod 17 is in contact with the lower end of the placement mold 13. Two support rods 17 are provided to support the placement mold 13 and improve the stability of the placement mold 13 when adjusting its position when it rotates.

A U-shaped waste box 18 is placed on the upper end of the support platform 1 . The U-shaped waste box 18 is located below the placement mold 13 . The U-shaped waste box 18 is used to store metal waste generated by punching the spoke body 14 and metal debris generated by grinding.

A positioning plate 19 is movably connected to the upper end of the placement mold 13. The diameter of the positioning plate 19 is larger than the inner diameter of the center hole 15. By rotating the positioning plate 19, the spoke body 14 is clamped and fixed to prevent the spoke body 14 from being offset during processing.

A placement plate 20 is fixedly installed on the outer surface of the placement mold 13, and the lower outer ring of the spoke body 14 is movably connected to the placement plate 20. The placement plate 20 cooperates with the placement mold 13 to support and limit the spoke body 14, thereby facilitating the processing of the spoke body 14.

As shown in Figure 4, the pushing mechanism 3 includes a cylinder 31, a circular plate 32 is fixedly installed at the output end of the cylinder 31, and the driving motor 4 is fixedly connected to the inner cavity of the circular plate 32. By providing the cylinder 31, a thrust is generated by hydraulic pressure, thereby pushing the circular plate 32 and the driving shaft 5 and the grinding head 7 to move downward, so that the punch 10 is pushed downward.

When in use, the positioning plate 19 is rotated to separate it from the placement mold 13, and the spoke body 14 is placed on the placement mold 13 and the placement plate 20, and then repositioned on the placement mold 13 through the positioning plate 19, and the positioning plate 19 is rotated to make it contact with the upper surface of the spoke body 14, and the spoke body 14 is fixed by the positioning plate 19. The cylinder 31 is provided to generate thrust through the hydraulic pressure, thereby pushing the circular plate 32 and the drive shaft 5 and the grinding head 7 to move downward, so as to push the punch 10 to move downward. The punch 10 is made of hard material, and the punch 10 is pressed down quickly to exert impact force on the spoke body 14, penetrating The spoke body 14 forms a wind-impinging hole, and the cylinder 31 further pushes the circular plate 32 to move downward, thereby driving the grinding head 7 to move downward. Since the diameter of the grinding head 7 is the same as the diameter of the punch 10, the grinding head 7 contacts the hole wall of the wind-impinging hole formed by the stamping of the spoke body 14 when it moves downward. The burrs in the wind-impinging hole are removed when the grinding head 7 reciprocates up and down. The driving shaft 5 is driven to rotate by the driving motor 4, thereby driving the grinding head 7 to rotate and further effectively remove the burrs in the wind-impinging hole. The up and down reciprocating motion enables the grinding head 7 to fully contact a larger surface area, thereby completely removing the burrs from the hole wall. At the same time, the rotating motion can ensure that the grinding head 7 applies force evenly on the hole wall, increasing the thoroughness of deburring. In general, the synchronous up and down reciprocating motion and rotation of the grinding head 7 can bring better deburring effect on the wall of the spoke punching hole, ensuring the quality and appearance of the hole wall. The metal waste generated by the punching of the spoke body 14 and the metal debris generated by grinding fall into the through groove 16, and fall vertically downward along the through groove 16 into the waste box 18 at the bottom for collection. By providing a first positioning screw 6 and a second positioning screw 8, the grinding head 7 with severe wear can be replaced by rotating the first positioning screw 6 and the second positioning screw 8, and the rotation is driven by the servo motor 12 The shaft 11 rotates, thereby driving the placement mold 13 to rotate and driving the spoke body 14 to rotate for position adjustment, making it convenient for the punch 10 to perform multiple air hole punching processing on the spoke body 14. By providing the punch 10 and the grinding head 7, and the punch 10 is located below the grinding head 7, the hole wall of the spoke body 14 can be deburred immediately after the punching processing, and there is no need to transport the spoke body 14 to another processing step for deburring. The reduced transportation steps simplify the production process of the spoke, shorten the overall production time, and improve the spoke production cycle. At the same time, there is no need to transport the spoke, thereby preventing the possibility of collision between the spoke and other objects, thereby ensuring the product quality of the spoke parts.
