Description

Technical Field

[0001] This utility model relates to the field of blanking technology for stamping machines, and more specifically to an automatic blanking device for a belt pulley stamping machine. Background Technology

[0002] The wheel mounted on the transmission belt is called a pulley, and the pulley relies on the transmission belt to transmit power. In actual use, there are two pulleys: a driving pulley and a driven pulley, with the transmission belt tightly fitted onto both. The production and processing of pulleys often uses a stamping machine. The stamping machine drives a flywheel through an electric motor, which in turn drives a crank-connecting rod mechanism via a clutch and transmission gears to move a slide up and down, thereby driving a stretching die to form the steel plate.

[0003] For example, a stamping device for processing pulleys, disclosed in the prior art (CN213968491U), facilitates the connection between the equipment base and the stamping structure through the cooperation of the base plate and the support plate. It also facilitates the connection of the extrusion plate through the cooperation of the connecting plate and the adjusting mechanism. Furthermore, the cooperation of the electric push rod and the connecting rod facilitates the movement of the adjusting mechanism by the moving rod. Finally, the cooperation of the sliding rod and the support plate facilitates the support of the driven rod, enabling the adjusting mechanism to move the extrusion plate. This provides support and fixation for the pulley, reduces deviation during processing, and offers good stability and high practicality.

[0004] However, the existing technology described above still has the following problems in use: during the process, after the belt pulley stamping is completed, it is necessary to manually remove the belt pulleys from the stamping groove one by one and arrange them neatly, which affects work efficiency. Based on this, the present invention provides an automatic unloading device for a belt pulley stamping machine that can improve work efficiency. Summary of the Invention

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides an automatic unloading device for a belt pulley stamping machine. A rotating mechanism drives multiple unloading rods to move into the belt pulley holes. Then, a driving mechanism drives three arc-shaped plates to move and firmly abut against the belt pulley hole wall, allowing multiple belt pulleys to be removed and unloaded at once. Furthermore, the device can neatly arrange multiple belt pulleys during unloading, eliminating the need for manual operation and thus improving the stamping efficiency of the belt pulleys, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a belt pulley stamping machine, comprising a mounting base on the belt pulley stamping machine, two feeding components on the top of the mounting base, each feeding component comprising a top plate, with multiple evenly distributed feeding rods running through the top plate, each feeding rod having multiple receiving slots on its outer wall, and an arc-shaped plate inside each receiving slot, the multiple arc-shaped plates being driven by a drive mechanism, a hollow cylinder I on the top of the mounting base, a hollow cylinder II inside the hollow cylinder I, and the hollow cylinder II being connected to the hollow cylinder I via a rotating mechanism, both top plates being detachably fixed to the hollow cylinder II.

[0007] In a preferred embodiment, each feeding rod has a cavity inside, and a connecting hole is provided between the cavity and a plurality of storage slots on the outer wall surface of the feeding rod. The connecting hole is provided for installing a drive mechanism for use.

[0008] In a preferred embodiment, the driving mechanism includes a motor fixed to the inner wall of the cavity. The bottom of the motor output shaft is connected to multiple lead screws via a bevel gear set. Each lead screw is threaded with a nut block, which passes through a connecting hole and is fixed to the arc plate. The motor and bevel gear set drive the multiple arc plates to move synchronously, thereby improving the material feeding efficiency.

[0009] In a preferred embodiment, both top plates are provided with mounting holes, and the top end of the feed rod passes through the mounting holes and is fixed to the top plate by fastening bolts, which facilitates the subsequent disassembly and replacement of the feed rod.

[0010] In a preferred embodiment, the rotating mechanism includes a motor detachably mounted on the top of the mounting base. A circular plate is fixedly mounted on the top of the motor output shaft, and an electric push rod is fixedly mounted on the top of the circular plate. The piston rod of the electric push rod is detachably connected to the hollow cylinder. The electric push rod drives the top plate to rise and fall, thereby automatically adjusting the height of the top plate and the unloading rod.

[0011] In a preferred embodiment, the mounting base has an annular slot at the top, the motor is located inside the annular slot, and the bottom of the hollow cylinder is inserted into the annular slot and fixed to the mounting base. The annular slot is used to fix and limit the hollow cylinder, which can greatly improve the stability of the hollow cylinder.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention uses a rotating mechanism to drive multiple feeding rods to move into the pulley holes. Then, a driving mechanism drives three arc-shaped plates to move and firmly abut against the pulley hole wall, allowing multiple pulleys to be removed at once for feeding. During feeding, multiple pulleys can be neatly arranged without manual operation, thereby improving the stamping efficiency of the pulleys. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides an automatic feeding device for a belt pulley stamping machine, including a mounting base 2 on the belt pulley stamping machine 1. The mounting base 2 has two feeding components 3 on its top. Each feeding component 3 includes a top plate 31, through which a plurality of evenly distributed feeding rods 32 are passed. Specifically, mounting holes 10 are provided on the top of both top plates 31. The top ends of the feeding rods 32 pass through the mounting holes 10 and are fixed to the top plates 31 by fastening bolts 11, which facilitates the subsequent disassembly and replacement of the feeding rods 32. A plurality of storage slots 33 are provided on the outer wall of each feeding rod 32, and an arc-shaped plate 34 is provided in the storage slot 33.

[0025] Each feeding rod 32 has a cavity 8 inside, and a connecting hole 9 is provided between the cavity 8 and multiple receiving grooves 33 on the outer wall surface of the feeding rod 32. The multiple arc plates 34 are driven by a drive mechanism 4. Specifically, the drive mechanism 4 includes a motor 41 fixed on the inner wall of the cavity 8. The bottom of the output shaft of the motor 41 is connected to multiple lead screws 43 through a bevel gear set 42. Each lead screw 43 is threaded with a nut block 44. The nut block 44 passes through the connecting hole 9 and is fixed to the arc plate 34. The motor 41 and the bevel gear set 42 drive the multiple arc plates 34 to move synchronously, thereby improving the feeding efficiency.

[0026] The mounting base 2 has a hollow cylinder 5 on its top, and a hollow cylinder 6 is provided inside the hollow cylinder 5. The hollow cylinder 6 is connected to the hollow cylinder 5 through a rotating mechanism 7. Both top plates 31 can be detachably fixed on the hollow cylinder 6. Specifically, the rotating mechanism 7 includes a motor 71 that is detachably mounted on the top of the mounting base 2. A circular plate 72 is fixedly provided on the top of the output shaft of the motor 71. An electric push rod 73 is fixedly provided on the top of the circular plate 72. The piston rod of the electric push rod 73 is detachably connected to the hollow cylinder 6.

[0027] In actual use, the operator first fixes the mounting base 2 to the front end of the belt pulley stamping machine 1. After the belt pulley stamping machine 1 stamps the belt pulley, the motor 71 drives the hollow cylinder 2 6 to rotate the two top plates 31. After one of the top plates 31 rotates to the top of the stamping groove, the piston rod of the electric push rod 73 is shortened, causing the unloading rod 32 on the top plate 31 to be inserted into the hole at the top of the belt pulley. Subsequently, the motor 41 drives the lead screw 43 that it drives to rotate simultaneously. The nut block 44 on the lead screw 43 drives the arc plate 34 under the limit of the connecting hole 9. After being removed from the receiving slot 33, the pulley is firmly abutted against the pulley hole wall by the three arc plates 34. Then, the piston rod of the electric push rod 73 extends to drive the unloading rod 32 to move upward, which automatically removes the pulley from the stamping slot. Then, the motor 71 drives the two top plates 31 to continue rotating, moving the removed pulley to the side of the pulley stamping machine 1. Then, the unloading rod 32 is controlled to move downward, and the multiple arc plates 34 retract back into the receiving slot 33, so that the pulley can be placed on the table without manual unloading, thereby improving the stamping efficiency of the pulley.

[0028] like Figure 3 As shown, an annular slot 12 is provided on the top of the mounting base 2. The motor 71 is located inside the annular slot 12. The bottom of the hollow cylinder 5 is inserted into the annular slot 12 and fixed to the mounting base 2. The annular slot 12 is used to fix and limit the hollow cylinder 5, which can greatly improve the stability of the hollow cylinder 5.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
