Technical Field

[0001] The utility model belongs to the technical field of shell processing, and particularly relates to a processing device for a flywheel shell. Background Art

[0002] As the fulcrum for power transmission, the flywheel housing's high degree of integrity and excellent physical and mechanical properties, such as compressive and tensile strength, are crucial for its proper function. Flywheel housings are typically produced using stamping, a process that utilizes the power of conventional or specialized stamping equipment to subject sheet metal to direct deformation forces within a die, resulting in a product with a defined shape, size, and performance.

[0003] During the stamping process of the flywheel housing, the sheet metal often fits very tightly to the mold under the action of the stamping power, which causes great inconvenience to the subsequent demoulding. In the existing technology, the mold and the stamped parts are usually separated by manually pulling the stamped parts. The actual operation is relatively cumbersome, which not only consumes the physical strength of the production personnel, but also leads to low efficiency of the entire flywheel housing stamping.

DETAILED DESCRIPTION

[0028] Example 1, specifically as Figures 1-6 shown.

[0029] like Figure 1 As shown, a flywheel housing processing device includes a mold body 1 and a lifting mechanism 3 for demolding. The mold body 1 is generally rectangular in shape, supported between the mold body 1 and the ground by four support legs 11 at its top corners. A circular stamping groove 2 is formed on the top surface of the mold body 1. A stamping power device presses the sheet material into the stamping groove 2 to form the flywheel housing of the desired shape.

[0030] The lifting mechanism 3 includes a cylindrical lifting rod 301 that passes through the center of the bottom of the stamping groove 2 in the vertical direction. That is, a limiting through-hole 12 is opened at the bottom of the stamping groove 2. The lifting rod 301 is slidably connected to the limiting through-hole 12, and the lifting rod 301 can be lifted and lowered in the height direction within the stamping groove 2. In order to prevent the lifting rod 301 from being separated from the limiting through-hole, a limiting groove 13 is opened on the periphery of the top opening of the limiting through-hole 12. The cross-section of the limiting groove 13 is circular and the inner diameter of the limiting groove 13 is larger than the inner diameter of the limiting through-hole 12. A limiting block 302 with the same size as the limiting groove 13 is welded to the top of the lifting rod 301. In the initial state, the limiting block 302 is completely in the limiting groove 13 to ensure the flatness of the bottom plate of the stamping groove 2.

[0031] A horizontally extending cylindrical support rod 310 is welded between the widthwise support legs 11. The middle portion of the support rod 310 is pivotally connected to the rectangular rotating rod 304. Specifically, a connecting hole is provided on the outer end of the rotating rod 304, extending in the direction of the support rod 310. The support rod 310 passes through the connecting hole, thus achieving a pivotal connection between the two. Specifically, the connecting hole is located on the outer side of the rotating rod 304, and the distance between the connecting hole and the outer end of the rotating rod 304 is one-third of the length of the rotating rod 304. A pedal 313 is welded to the outer end of the rotating rod 304 to facilitate production personnel applying force to the rotating rod 304.

[0032] A rectangular connecting rod 303 is welded to the bottom of the lifting rod 301 in the vertical direction, and the free end of the connecting rod 303 is located on the upper left of the inner end of the rotating rod 304. The free end of the connecting rod 303 and the inner end of the rotating rod 304 are rotatably connected through a transmission rod 309, wherein a first slot 305 is provided on the free end of the connecting rod 303, and a first rotating shaft 307 is welded between the two side walls of the first slot 305 along the width direction of the first slot 305. A second slot 306 is provided on the inner end of the rotating rod 304, and a second rotating shaft 308 is welded between the two side walls of the second slot 306 along the width direction of the second slot 306. The two ends of the transmission rod 309 are rotatably connected to the first rotating shaft 307 and the second rotating shaft 308 respectively.

[0033] During use, first, the sheet material is stamped and formed by the stamping power device, and then the production personnel apply downward pressure to the pedal 313 through their limbs. During this process, the outer end of the rotating rod 304 rotates clockwise around the support rod 310, and the inner end of the rotating rod 304 rotates counterclockwise around the support rod 310, and the lifting rod 301 is driven to rise through the transmission rod 309. The limit block 302 on the top of the lifting rod 301 rises synchronously and pushes the stamping part upward, thereby realizing rapid demolding of the stamping part; finally, as the demolding of the stamping part is completed, the lifting rod 301 can be lowered and the limit block 302 can return to its initial state under the action of the self-weight of the jacking structure 3 or by manually moving the pedal 313 upward.

[0034] In order to achieve automatic recovery of the lifting mechanism 3, a circular fixed plate 311 is welded to the periphery of the lifting rod 301. The fixed plate 311 is close to the lower end surface of the lifting rod 301. A vertical first spring 312 is provided between the fixed plate 311 and the mold body 1. The first spring 312 is sleeved on the periphery of the lifting rod 301. The top end of the first spring 312 is welded to the bottom surface of the mold body 1, and the bottom end of the first spring 312 is welded to the upper surface of the fixed plate 311. When demolding begins, the pedal 313 is pressed downward, and the fixed plate 311 rises synchronously with the lifting rod 301, compressing the first spring 312. After demolding is completed, the pedal 313 is released. Under the rebound action of the first spring 312, the pedal 313 moves upward, and the lifting rod 301 descends and returns to its initial state, that is, the limit block 302 is completely in the limit groove 13. By providing the fixing plate 311 and the first spring 312 , when demoulding is completed, the lifting column 301 , the limit block 302 and other components can be quickly and accurately returned to their original positions, preparing for the next stamping, which is beneficial to improving the working efficiency of continuous stamping.

[0035] A horizontal limit plate 314 is also provided on the outer periphery of the lifting rod 301. The limit plate 314 is located below the fixed plate 311. The limit plate 314 is welded to the support leg 11. The lifting rod 301 is slidably connected to the limit plate 314. The limit plate 314 can limit the bottom end of the lifting rod 301, further ensuring that the lifting rod 301 can only move in the vertical direction, preventing the lifting rod 301 from being stuck with the limit through hole 12.

[0036] During the stamping process, the speed is often very fast, so that the air under the sheet material cannot be discharged in time along the wall of the stamping groove 2. If the thickness of the sheet material is relatively thin, it is easy to cause a bulge on the bottom of the shell, thus affecting its use. Based on this, an exhaust channel 4 is opened inside the lifting rod 301. The air inlet of the exhaust channel 4 is located at the center position of the top surface of the limit block 302. The exhaust channel 4 extends downward in the vertical direction to the bottom end of the connecting rod 303, and its air outlet is located on the side wall of the connecting rod 303. A baffle 5 with the same size as the air inlet is provided at the air inlet of the exhaust channel 4. The upper surface of the baffle 5 is flush with the top surface of the limit block 302, and a plurality of air holes 51 are provided on the baffle 5. Through the setting of the exhaust channel 4 and the baffle 5, the air under the sheet material can be discharged in time through the exhaust channel, preventing the compressed air from causing bulges and other deformations on the bottom plate of the shell during the stamping process.

[0037] During the demolding process, there is usually a large friction between the side wall of the shell and the wall of the punching groove 2. Therefore, a lubrication mechanism 6 is added to the existing mold body 1. The lubrication mechanism 6 includes an annular oil storage tank 61 opened on the top surface of the mold body 1 at the periphery of the punching groove 2. A plurality of vertical rods 63 are evenly spaced along the circumferential direction in the oil storage tank 61. The bottom of the vertical rod 63 is welded to the bottom of the oil storage tank 61. A truncated cone-shaped sliding block 64 is slidably connected to the vertical rod 63. A second spring 65 is provided between the bottom surface of the sliding block 64 and the bottom of the oil storage tank 61. The second spring 65 is sleeved on the periphery of the vertical rod 63. The second spring 65 is used to support the sliding block 64, and the sliding block 64 can move up and down along the vertical rod. An annular plate 62 for sealing the oil storage tank 61 is welded at the opening of the oil storage tank 61. A through hole corresponding to the sliding block 64 is opened on the annular plate 62. In the initial state, the upper part of the sliding block 64 is exposed outside the annular plate 62 and the side of the sliding block 64 can completely seal the through hole.

[0038] A collecting barrel 66 is provided below the air outlet of the exhaust channel 4, and the air outlet of the exhaust channel 4 is connected to the collecting barrel 66 through a pipeline. An oil replenishment pump 67 (model SMP2-30 / 5S) is provided on one side of the collecting barrel 66. An oil inlet channel 68 is provided on the bottom side wall of the oil storage tank 61. The oil inlet of the oil replenishment pump 67 is connected to the collecting barrel 66 through a pipeline, and the oil outlet of the oil replenishment pump 67 is connected to the oil inlet channel 68.

[0039] During use, the oil reservoir 61 is filled with lubricating oil, the sheet metal presses down the sliding block 64, the sliding block 64 moves down along the vertical rod 63, the second spring 65 is compressed, and a gap appears between the side of the sliding block 64 and the through hole of the annular plate 62. The lubricating oil in the oil reservoir 61 flows out from the gap under the squeezing action of the sliding block 64 and adheres to the bottom surface of the sheet metal. The lubricating oil on the bottom surface of the sheet metal will smear the stamping groove 2 during the stamping process, thereby reducing the friction between the side of the shell and the wall of the stamping groove 2, preventing damage to the shell and the mold body while further accelerating the demoulding efficiency. When one stamping is completed, the lubricating oil on the wall of the stamping groove 2 will be concentrated at the bottom of the groove, and in the next stamping process, it will enter the collection barrel 66 through the exhaust channel 4. The collection barrel 66 will also store sufficient lubricating oil. The lubricating oil in the collection barrel 66 is continuously replenished to the oil reservoir 61 along the oil inlet channel 68 through the oil replenishing pump 67 to ensure that the lubricating oil fills the oil reservoir 61.
