Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts processing technology, specifically a stamping device for processing motorcycle parts. Background Technology

[0002] Stamping is a manufacturing technology that uses the power of conventional or specialized stamping equipment to directly deform a workpiece within a die, thereby obtaining product parts with specific shapes, dimensions, and properties. The workpiece, die, and equipment are the three essential elements of stamping. Based on the temperature of the stamping process, stamping can be divided into hot stamping and cold stamping. Hot stamping is suitable for processing sheet metal with high deformation resistance and poor plasticity; cold stamping is performed at room temperature and is a commonly used stamping method for thin sheets.

[0003] The existing utility model patent with publication number CN216881346U discloses a stamping device for motorcycle parts, including a fixed machine base with a frame above it; a stamping die on the machine base, and a stamping machine corresponding to the stamping die on the frame; a rotating clamping fixture on the side of the stamping die, comprising a shaft, a limiting rod, a sleeve, a reset component, and a clamp; the rotating clamping fixture rotates via the shaft by being located on the side of the stamping die. In use, the clamping fixture can be rotated from above the stamping die to other positions for easy operation. The semi-finished part to be stamped is simply loaded into the clamping fixture manually, and then the clamping fixture is rotated to align with the limiting rod and the stamping die, making positioning simple. When the stamping machine stamps the semi-finished part, the clamping fixture moves downward along the shaft via the sleeve, accurately aligning the semi-finished part into the stamping die for stamping. After stamping, the clamping fixture is reset by the reset component, completing demolding.

[0004] Each time the above-mentioned stamping device completes a stamping operation, the operator needs to manually release the elastic buckle, rotate the fixture to remove the part, and then manually rotate the fixture to reset and lock it. The operator needs to frequently operate in the area directly below the stamping die. If the stamping machine accidentally descends due to a malfunction, there is a safety hazard to the hands. At the same time, after repeated compression, the spring will weaken due to metal fatigue, resulting in the parts not being able to be completely demolded. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stamping device for processing motorcycle parts, which solves the problems of spring elasticity affecting demolding and low safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A stamping device for processing motorcycle parts includes a base plate, and a stamping mechanism is arranged above the base plate for pressing a metal plate to form the metal plate. The stamping mechanism includes:

[0007] The limiting assembly includes a rodless cylinder fixedly installed above a base plate. A support frame is fixedly installed above the slider of the rodless cylinder. A stepping turntable is fixedly installed above the support frame. A connecting plate is fixedly installed above the stepping turntable. A limiting frame is fixedly installed above the connecting plate. A movable frame is inserted through the inner side of the limiting frame. A ball bearing is fitted into one side of the movable frame. A lead screw is inserted through the center of the ball bearing.

[0008] A drive assembly, positioned above the base plate, is used to provide pressure for stamping metal sheets.

[0009] Preferably, the drive assembly includes a lifting cylinder fixedly installed inside the base plate, a bottom mold fixedly installed at the top of the lifting cylinder, linear bearings sleeved on both sides of the bottom mold, a fixing frame fixedly installed above the base plate, a pressing cylinder fixedly installed at the top of the fixing frame, a fixing plate fixedly installed at the bottom of the pressing cylinder, a cylinder body fixedly installed below the fixing plate, a counterweight installed above the cylinder body, a piston installed below the cylinder body, a sealing ring installed between the counterweight and the outer side of the piston, and a fixed mold fixedly installed at the bottom of the piston.

[0010] Preferably, the limiting frame is connected to the stepping turntable via a connecting plate, and the movable frame has columnar structures on both sides, forming a sliding connection between the movable frame and the limiting frame.

[0011] Preferably, the movable frame is installed symmetrically on both sides of the limiting frame, and the lead screw is rotatably connected to the movable frame through ball bearings. The lead screw is also movably connected to the limiting frame through a threaded structure.

[0012] Preferably, the bottom mold has columnar structures on both sides, the bottom mold is slidably connected to the base plate through linear bearings, and the bottom of the bottom mold is fixedly connected to the top of the lifting cylinder.

[0013] Preferably, the pressing cylinder is mounted directly above the lifting cylinder via a fixing bracket, the counterweight is slidably connected to the cylinder body, a ring-shaped structure is provided at the center of the cylinder body, and the piston is slidably connected to the cylinder body.

[0014] Beneficial effects

[0015] This utility model provides a stamping device for processing motorcycle parts. Compared with the prior art, it has the following advantages:

[0016] (1) The stamping device for processing motorcycle parts, after stamping, controls the lifting cylinder to retract, and the bottom mold connected to its top moves downward accordingly. At the same time, the pressing cylinder retracts, driving the fixed plate and the cylinder below it to rise synchronously. The piston inside the cylinder moves upward along with the cylinder, as the cylinder rises and there is no downward pressure. Through the precise extension and retraction control of the lifting cylinder and the pressing cylinder, the bottom mold and the fixed mold can be stably and completely separated. This rigid drive structure will not suffer from metal fatigue due to long-term use like a spring, avoiding the problem of incomplete demolding caused by reduced elasticity, and ensuring that the parts can smoothly detach from the mold and fall onto the movable frame after each stamping.

[0017] (2) The stamping device for processing motorcycle parts reduces direct contact between operators and the stamping area through an automated feeding and picking structure, thereby improving safety. Operators only need to place the metal plate to be processed between the adjusted movable frames in a safe area away from directly below the stamping die. Then, the stepping turntable drives the limit frame to rotate through the connecting plate, transferring the unstamped metal plate to the stamping area. Then, the rodless cylinder drives the support frame to move, accurately sending the metal plate between the fixed die and the bottom die. There is no need to manually push the material directly below the die. After stamping, the rodless cylinder and the stepping turntable will automatically transfer the formed parts to the safe area. During the whole process, operators do not need to unlock or rotate the fixture directly below the stamping die, avoiding hand safety hazards caused by accidental downward movement due to stamping machine failure.

[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] Please see Figure 1-4 This utility model provides a technical solution: a stamping device for processing motorcycle parts includes a base plate 1, and a stamping mechanism 2 is arranged above the base plate 1 for extruding metal plates to form metal plates. The stamping mechanism 2 includes: a limiting component 21, including a rodless cylinder 211 fixedly installed above the base plate 1, a support frame 212 fixedly installed above the slider of the rodless cylinder 211, a stepping turntable 213 fixedly installed above the support frame 212, a connecting plate 214 fixedly installed above the stepping turntable 213, and a limiting frame 215 fixedly installed above the connecting plate 214. The inner side of the limiting frame 215 is inserted... A movable frame 216 is installed, with a ball bearing 217 fitted on one side of the movable frame 216. A lead screw 218 is inserted through the center of the ball bearing 217. A limit frame 215 is connected to a stepping turntable 213 via a connecting plate 214. Columnar structures are provided on both sides of the movable frame 216. A sliding connection is formed between the movable frame 216 and the limit frame 215. The movable frame 216 is installed symmetrically on both sides of the limit frame 215. The lead screw 218 is rotatably connected to the movable frame 216 via the ball bearing 217. The lead screw 218 is movably connected to the limit frame 215 via a threaded structure.

[0025] Specifically, the rodless cylinder 211 can drive the support frame 212 to move. Since the lead screw 218 is connected to the limit frame 215 through a threaded structure, and the end is connected to the movable frame 216 through the ball bearing 217, the columnar structures on both sides of the movable frame 216 are inserted into the interior of the limit frame 215. When the lead screw 218 is rotated, the position of the movable frame 216 can be adjusted to adjust the spacing of the movable frame 216 to accommodate metal plates of different sizes. After the metal plate is placed between the movable frames 216, the stepping turntable 213 adjusts the orientation of the limit frame 215 and adjusts the unstamped metal plate to the other side of the support frame 212 by rotation. Then, the rodless cylinder 211 drives the support frame 212 to move and adjust the metal plate to the space between the fixed mold 2211 and the bottom mold 222.

[0026] A drive assembly 22, positioned above the base plate 1, provides pressure for stamping metal plates. The drive assembly 22 includes a lifting cylinder 221 fixedly installed inside the base plate 1. A bottom mold 222 is fixedly installed at the top of the lifting cylinder 221. Linear bearings 223 are sleeved on both sides of the bottom mold 222. A fixing frame 224 is fixedly installed above the base plate 1. A pressing cylinder 225 is fixedly installed at the top of the fixing frame 224. A fixing plate 226 is fixedly installed at the bottom of the pressing cylinder 225. A cylinder body 227 is fixedly installed below the fixing plate 226. A counterweight 228 is fitted above the cylinder body 227, and a counterweight 228 is fitted below the cylinder body 227. There is a piston 229, a counterweight 228 and a sealing ring 2210 fitted on the outside of the piston 229, a fixed mold 2211 fixedly installed at the bottom end of the piston 229, columnar structures are provided on both sides of the bottom mold 222, the bottom mold 222 is slidably connected to the base plate 1 through a linear bearing 223, the bottom of the bottom mold 222 is fixedly connected to the top of the lifting cylinder 221, the pressing cylinder 225 is installed directly above the lifting cylinder 221 through a fixing bracket 224, the counterweight 228 is slidably connected to the cylinder body 227, a ring-shaped structure is provided at the center of the cylinder body 227, and the piston 229 is slidably connected to the cylinder body 227.

[0027] Specifically, the lifting cylinder 221 can drive the bottom mold 222 to move upward. The linear bearing 223 is fixed above the base plate 1 to reduce the friction between the bottom mold 222 and the base plate 1, and at the same time restrict the movement direction of the bottom mold 222. The pressing cylinder 225 can drive the fixed plate 226 and the cylinder body 227 to move downward. A columnar structure is provided above the counterweight 228, which penetrates the fixed plate 226. The cylinder body 227 is filled with hydraulic oil. When the pressing cylinder 225 extends, the fixed mold 222... After the metal plate is clamped by the bottom mold 222, as the pressing cylinder 225 continues to extend, the piston 229 will push the hydraulic oil upward, lifting the counterweight 228 until the counterweight 228 contacts the fixed plate 226, thereby buffering during the stamping process. After the stamping is completed, the lifting cylinder 221 and the pressing cylinder 225 retract, causing the bottom mold 222 and the fixed mold 2211 to separate. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0028] During operation, the lead screw 218 is first rotated. The lead screw 218 is rotatably connected to the movable frame 216 via ball bearings 217 and movably connected to the limiting frame 215 via a threaded structure. Simultaneously, the cylindrical structures on both sides of the movable frame 216 are slidably connected within the limiting frame 215. Rotating the lead screw 218 adjusts the spacing of the movable frames 216 to accommodate the size of the metal plate to be processed. The metal plate is then placed between the movable frames 216. The stepping turntable 213, via the connecting plate 214, drives the limiting frame 215 to adjust its orientation, transferring the unpressed metal plate to the other side of the support frame 212. Next, the rodless cylinder 211 moves the support frame 212 above its slider, conveying the metal plate between the fixed mold 2211 and the bottom mold 222. The linear bearing 223 is fixed above the base plate 1, used to limit the movement direction of the bottom mold 222 and reduce friction. When the lifting cylinder 221 extends, it can drive the bottom mold 222 along the linear bearing 223. As the plate slides upward, the downward pressure cylinder 225 at the top of the fixed frame 224 drives the fixed plate 226 and the cylinder 227 below it to move downward, causing the fixed mold 2211 to gradually approach the metal plate. After the fixed mold 2211 clamps the metal plate with the bottom mold 222, the downward pressure cylinder 225 continues to extend, and the piston 229 pushes the hydraulic oil upward in the cylinder 227, lifting the counterweight 228 above the cylinder 227 until the counterweight 228 contacts the fixed plate 226, thus achieving the punching action. The pressure buffer completes the metal sheet forming; after the stamping is completed, the lifting cylinder 221 retracts to drive the bottom mold 222 to descend, and the pressing cylinder 225 retracts to drive the fixed plate 226, cylinder body 227 and fixed mold 2211 to rise, so that the fixed mold 2211 separates from the bottom mold 222. Finally, the rodless cylinder 211 and the stepping turntable 213 cooperate to turn out the formed parts. The counterweight block 228 and the fixed mold 2211 will cause the hydraulic oil to flow back under their own weight, completing one work cycle.
