Description

Technical Field

[0001] The present invention relates to the technical field of industrial production equipment, and particularly to a sprocket stamping device. Background Art

[0002] A sprocket mainly consists of parts such as teeth, hubs, and spokes. The teeth are the key parts that mesh with the chain, and their shape and size directly affect the transmission performance; the hub is used to be installed on the shaft to achieve power transmission; the spokes connect the teeth and the hub, playing a role in supporting and transmitting force.

[0003] A sprocket stamping device is a device used for stamping sprockets. It is mainly used to process raw materials such as sheets into sprockets with specific shapes and sizes through stamping. When manufacturing a sprocket, the blank is pressed out with teeth arranged in a ring by the sprocket stamping device, and the quality of the sprocket forming process determines the transportation efficiency and service life of the conveyor machinery.

[0004] The patent with the publication number of CN117340171A discloses a tooth pressing device for sprockets, including a machine tool and a workbench for sprocket tooth pressing. A transmission motor is arranged on one side of the machine tool, and a transmission mechanism is installed inside the machine tool. The transmission mechanism is in contact with one end of the transmission motor. A support one is arranged above one side of the machine tool; a support two is arranged above the other side of the machine tool; by installing a transmission mechanism inside the machine tool, and the transmission mechanism is designed with a main conveyor belt and a sub-conveyor belt symmetrically. Through the symmetrical design, one end of one elevator can pass through the inside of the machine tool and be located above the machine tool. When an unprocessed wheel blank one is placed above the transmission mechanism at one end, it can be transmitted through the transmission to be located directly below the hydraulic box. The bottom of the wheel blank one can be lifted to the center position inside the hydraulic box by the lifting head for tooth pressing processing. When the processing is completed, the lifting head can be retracted to make the wheel blank one fall above the transmission mechanism. Through the transmission of the transmission mechanism, the wheel blank one is transmitted directly below the support two, and then it can be lifted by another lifting head to facilitate the tool box to remove the burrs on the appearance of the sprocket. Through the cooperation of the transmission mechanism and the elevator, the automated process of sprocket tooth pressing processing and burr removal is completed, improving the efficiency of sprocket tooth pressing processing.

[0005] In the above technical solution, the unprocessed wheel blank one is placed above the transmission mechanism at one end. The bottom of the wheel blank one can be lifted to the center position inside the hydraulic box by the lifting head for tooth pressing processing. However, it cannot be guaranteed that the center of the wheel blank exactly corresponds to the lifting head, which may lead to the problem that the lifting head drops when lifting the wheel blank. Moreover, if the wheel blank is not lifted in a centered manner, the subsequent stamping operation cannot be carried out smoothly. Therefore, there is an urgent need for a sprocket stamping device to solve the above-mentioned problems. Summary of the Invention

[0102] The working principle of the present invention is as follows:

[0103] Place the wheel blank on the conveying mechanism 4. The side rods 409 on both sides are responsible for supporting the wheel blank. The outer conveyor belt 405 moves the wheel blank to the positioning plate mechanism 2 by driving the second roller column 407 to rotate through the motor. Before that, adjust the position of the positioning components on the panel 209 through the first hydraulic column 301, and at the same time replace a suitable collar 306 to assist in the adjustment, so that the distance between adjacent positioning components adapts to the diameter of the wheel blank. In this way, when the conveying mechanism 4 conveys the wheel blank, if there is a side shift, the unilateral positioning components can block in the direction of the side shift, and then cooperate with the conveying of the outer conveyor belt 405 to guide the wheel blank onto the positioning plate mechanism 2, improving the smoothness of the wheel blank positioning.

[0104] After the wheel blank is moved onto the positioning plate mechanism 2, retract the first hydraulic column 301 to synchronously retract the positioning components along the middle groove 210 and the sliding groove 211. The synchronous retraction of the positioning components on the four sides can directly position the wheel blank in the center of the main board 201, that is, the central axis of the wheel blank is aligned with the central axis of the main board 201, effectively positioning the central hole of the wheel blank.

[0105] After the wheel blank is positioned, start the second hydraulic column 501 to make the stamping head assembly move downward to punch the central hole of the wheel blank. The lower end of the stamping head assembly contracts in equal proportion, so that the wheel blank is gradually stressed. The waste material punched off from the central hole falls through the central hole and the waste hole 202 of the support plate 204. The upper surface of the column disk 302 is an annular slope surface, which slopes downward from the center of the column disk 302 to the edge. The fallen waste material can automatically slide into the bottom frame 101 for collection, improving the waste material collection capacity.

[0106] On the side of the main column 508, there is a side column 509. The central hole of the wheel blank is stamped into the shape of the stamping head assembly. At this time, when the pressure plate 507 fits the wheel blank, that is, when the first stamping mechanism 5 stamps the central hole of the wheel blank in place, the first gear 510 and the second gear 602 are flush and engaged. Then, the first gear 510 can be driven to rotate by the auxiliary mechanism 6, and then the stamping head assembly directly drives the wheel blank to rotate for subsequent stamping of the tooth part, saving the steps of switching between central hole stamping and tooth part stamping, saving the working procedures, and simplifying the processing procedures.

[0107] By symmetrically arranging the second stamping mechanisms 7 at the centers on both sides of the wheel blank, the stamping forces on the tooth parts of the wheel blank are relatively offset. And a grinding mechanism 8 is arranged on the side of the second stamping mechanism 7 to grind the tooth parts just after stamping, so as to assist in shaping the tooth parts, making the overall stamping force on the tooth parts of the wheel blank uniform and improving the stamping quality of the tooth parts of the wheel blank.

[0108] Due to the arrangement of the grinding mechanism 8 on the side of the second stamping mechanism 7, the freshly stamped tooth parts of the second stamping mechanism 7 will directly fall into the working range of the grinding mechanism 8 during rotation. The grinding belt 810 of the grinding mechanism 8 grinds the inner wall and periphery of the tooth parts under the rotation of the first roller 805, and can effectively remove the burrs of the tooth parts in a timely manner.

[0109] Through the connection of the connecting belt 9 to the first pulley 706 and the second pulley 808, when stamping the tooth parts, the connecting belt 9 drives the first pulley 706 to rotate, and then the grinding wheel 704 at the end of the third stamping block 702 also rotates accordingly, enabling rough grinding while stamping the tooth parts and further improving the working efficiency.

[0110] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
