Description

Technical Field

[0001] The invention relates to the technical field of buffer block production, in particular to a guide rail buffer block and a punching device thereof. Background Art

[0002] Automotive side door systems often face complex operating environments. They must not only withstand changing environmental conditions like rain and sun, but also require rubber buffers to cushion the reciprocating motion of moving parts. Conventional buffers are typically designed as single rubber components. However, due to their inherent shape and structure, existing rubber components lack sufficient grip on the side door guide rails, easily causing the components to come loose and fail.

[0003] After rubber bumpers are manufactured and formed, flash easily forms on their edges. Manual cleaning is commonly used for bumpers with complex geometries. However, for mass-produced, simpler rubber bumps, flash removal is performed using a punching device. Because rubber is inherently soft and elastic, conventional punching devices can easily damage the rubber if the punching position is too close to the main body of the rubber bump, while further away from the main body can easily leave flash residue. Therefore, improvements are necessary. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

In this embodiment, the buffer portion 1 is designed to be cubical and is used to bear external impact to achieve buffering. A hanging portion 2 is provided on the top of the buffer portion 1, and the hanging portion 2 is used to connect with an external component to achieve the overall limit of the buffer block. One end of the hanging portion 2 is protruded to form an extension section. Due to the existence of the extension section, the hanging portion 2 is overall in the shape of a rectangular parallelepiped, and the cross-sectional size of the hanging portion 2 is larger than the cross-sectional size of the buffer portion 1; a slide groove 5 is provided between the hanging portion 2 and the buffer portion 1, and the slide groove 5 is used to be slidably connected to the guide rail to achieve the installation of the buffer block.

The hanging portion 2 is located above the guide rail for limiting the buffer block, and the direction of the extension section is the impact contact direction between the moving component and the buffer block. Therefore, the existence of the extension section can expand the contact area between the hanging portion 2 and the guide rail, thereby further improving the installation stability of the buffer block.

[0033] See also Figure 3 A through hole 4 is formed in the middle of the rubber part, and a plastic part 3 is fixedly installed at one end of the through hole 4. The plastic part 3 includes a docking sleeve located inside the buffer block, and a plastic clip is fixedly connected to one side of the docking sleeve; the plastic part 3 and the rubber part are assembled by vulcanization. The guide rail buffer block proposed in this application is used in the guide rail position of the automobile side door. Because the working conditions of the automobile side door system are complex and changeable, conventional buffer blocks are usually designed as a single rubber part. However, due to the shape and structure of the existing rubber parts, the clamping force between them and the side door guide rail components is insufficient, which can easily cause the parts to fall out and fail. The guide rail buffer block of the present application adopts a specially designed rubber part structure, and uses structures such as a slide groove 5 and a hanging part 2 to achieve stable installation and docking with the guide rail structure, and a buffer part 1 with a square body is provided to ensure stable bearing of the impact of the moving component; at the same time, the design concept of combining plastic parts 3 and rubber parts is used, which combines the support and holding force of the plastic parts 3 and cleverly utilizes the resilience and buffering properties of the rubber parts. The overall structure of the buffer block is novel, the supporting force is strong, and the risk of the buffer block falling off and failing can be avoided.

[0036] See also Figure 6 In order to facilitate the transfer of multiple buffer blocks in a stacked state on the feed plate 202, the present application rotatably installs a feed conveyor belt 203 on the top of the feed plate 202. Through the rotation of the feed conveyor belt 203, the buffer block is driven to move and fall stably along the feed plate 202 to avoid buffer block block jam; a limiting groove 204 is provided on one side of the feed plate 202, and the extension section on the buffer block is limited by the limiting groove 204 to ensure that the position of the buffer block is stable during the loading and movement process, and a feed guide wheel 205 is rotatably installed on the bottom of the inner wall of the limiting groove 204, and the top of the feed guide wheel 205 protrudes from the top of the limiting groove 204. By setting the feed guide wheel 205 to contact the extension section, the resistance of the buffer block during movement is reduced.

[0037] See also Figure 4The conveying mechanism includes a conveying frame 301, which is embedded in the machine platform 101, and the top surface height of the conveying frame 301 is consistent with the top surface height of the machine platform 101. Conveying guide rails 302 are fixedly installed on both sides of the inner wall of the conveying frame 301, and a receiving plate 303 is slidably installed on the inner walls of the two conveying guide rails 302. A clamping groove 304 is provided on one side of the top of the receiving plate 303, and the clamping groove 304 corresponds to the extension section. When the material-taking cylinder 209 installs the buffer block on the receiving plate 303, the clamping groove 304 can be used to connect with the extension section to achieve the installation of the buffer block. In order to further improve the stability of the buffer block during transportation and subsequent punching, the present application sets a limiting column 305 in the middle of the receiving plate 303, and uses the limiting column 305 to correspond to the through-hole to limit the buffer block.

[0038] See also Figure 8 In order to facilitate the separation and removal of the buffer block after punching, an adjusting piece is provided at the bottom of the receiving plate 303, and the adjusting piece includes a shell 306. The middle part of the shell 306 is slidably connected with an adjusting rack 309. The top of the adjusting rack 309 is fixedly connected to the bottom of the limiting column 305. Drive motors are provided on both sides of the inner wall of the shell 306. The output end of the drive motor is fixedly connected with a drive gear 310.

[0039] The outer wall of the limiting column 305 is provided with a push ring 307, and both sides of the inner wall of the shell 306 are slidably connected with a lifting rack 308. One side of the two lifting racks 308 is respectively engaged with two driving gears 310. By setting the push ring 307 and using the lifting rack 308 to engage it with the driving gear 310, when the driving gear 310 rotates to drive the limiting column 305 to descend and shrink, the lifting rack 308 drives the push ring 307 to be pushed out, thereby driving the buffer block to complete the separation from the receiving plate 303.

[0040] See also Figure 1 The punching mechanism includes a punching frame 401, a punching cylinder 402 is fixedly installed on the top of the punching frame 401, a punching head 403 is fixedly connected to the output end of the punching cylinder 402, and a punching blade is fixedly connected to the bottom edge of the punching head 403. The contour position of the punching blade is consistent with the edge contour of the buffer block, so as to achieve the punching of the flash on the edge of the buffer block; since the flash on the upper and lower edges of the buffer block are adhered after forming, in order to remove the two layers of flash synchronously in one punching action, please refer to Figure 5A cavity is provided inside the punching head 403 to accommodate the entry of the buffer block. The inner wall edge of the cavity is rotatably connected to a number of friction rollers 404. Through the rotation of the friction rollers 404, the edge position of the buffer block after trimming is polished to fully remove the remaining flash.

[0041] In order to reduce the damage to the buffer block caused by the grinding operation, an oil filling pipe 406 is fixedly connected to one side of the punching head 403, and a plurality of diversion pipes 405 are fixedly connected to the bottom of the oil filling pipe 406. The plurality of diversion pipes 405 are respectively arranged corresponding to the plurality of friction rollers 404. One end of the oil filling pipe 406 is connected to the output end of the external oil filling pump, that is, the oil filling pipe 406 and the diversion pipe 405 are used to send lubricating oil toward the friction roller 404, and the rotation of the friction roller 404 coats the lubricating oil on the buffer block, so that the punching position of the burr is smoother and flatter; at the same time, the presence of lubricating oil can also reduce the friction resistance between the inner wall of the cavity and the buffer block, making it convenient to lift and separate the punching head 403.

[0042] See also Figure 1 and Figure 9 In order to automatically discharge the buffer blocks that have completed punching, discharging racks 501 are fixedly installed on both sides of the inner wall of the punching rack 401, and a pushing motor 502 is fixedly installed on the inner wall of the discharging rack 501. The output end of the pushing motor 502 is fixedly connected to the discharging push rod 503, and a through slot is provided on one side of the discharging rack 501. The end of the machine table 101 close to the punching rack 401 is fixedly connected to the discharging guide slot 102, and the height of the discharging guide slot 102 is consistent with the height of the through slot, so that the discharging push rod 503 can stably pass through the discharging guide slot 102 and move to the outside of the discharging rack 501 to push and discharge the buffer blocks. One end of the discharging guide slot 102 corresponds to one end of the conveyor belt; a cleaning fan 504 is fixedly installed on the top of the inner wall of the discharging rack 501, and the air outlet direction of the cleaning fan 504 is toward the end of the conveyor rack 301.

[0043] When the present invention is in use, a plurality of buffer blocks are manually arranged and stacked on the feed plate 202, and the plastic inlet end is upward, the extension section is located in the limit groove 204 and contacts the feed guide wheel 205; then the feed conveyor belt 203 is started to drive the various buffer blocks thereon to move downward, and when the buffer blocks move to the position of the temporary storage plate 206, the negative pressure suction cup 210 is driven downward by the material taking cylinder 209, and the negative pressure suction cup 210 is used to realize the material taking operation of the buffer blocks, and then the material taking guide rail 208 drives the material taking cylinder 209 to start, so that the position of the buffer blocks corresponds to the position of the receiving plate 303, and then the material taking cylinder 209 drives the buffer blocks to be pressed down, so that the extension section is docked with the clamping groove 304, and the limit column 305 is synchronously inserted into the through hole 4 to realize the installation and placement of the buffer blocks, and then the material taking guide rail 208 and the material taking cylinder 209 are reset;

[0044] The receiving plate 303 is driven by the conveying guide rail 302 to move to the bottom of the punching frame 401. The punching cylinder 402 is activated to drive the punching head 403 to press down, and the flash on the buffer block is punched out by the movement of the punching blade. During the punching process, the rotation of the friction roller 404 cleans the flash impurities and the like remaining on the outer wall of the buffer block, and the oil injection pipe 406 and the diverter pipe 405 are used to transport lubricating oil to the outer wall of the friction roller 404. The rotation of the friction roller 404 coats the lubricating oil on the buffer block to maintain the buffer block and reduce the resistance between the buffer block and the inner cavity to prevent the buffer block from being adsorbed inside the punching head 403.

[0045] After the punching is completed, the punching cylinder 402 drives the punching head 403 to lift up. At this time, the driving motor is started to drive the driving gear 310 to rotate, thereby driving the adjusting rack 309 to descend, and then driving the docking column to descend and disengage from the through hole 4. At the same time, the rotation of the driving gear 310 drives the jacking rack 308 to lift, and the push ring 307 is pushed out, and then the buffer block is lifted up, so that the extension section is separated from the clamping groove 304; at this time, the pushing motor 502 is started to drive the discharging push rod 503 to rotate, The punch block is pushed away from the receiving plate 303, causing it to fall into the discharge guide trough 102 for discharge. At the same time, the cleaning fan 504 is started to send air to the top surface of the receiving plate 303 to blow away the flash waste. Then the conveying guide rail 302 is restarted, driving the receiving plate 303 to move to the position corresponding to the material removal cylinder 209 in the loading box 201 to facilitate the subsequent buffer block loading operation. After a period of use, the flash waste on the receiving plate 303 and scattered inside the conveying rack 301 is cleaned.
