Description

Technical Field

[0001] The present invention relates to the technical field of automobile component stamping processing, in particular to an automobile component stamping mechanism and a use method thereof. Background Art

[0002] Automotive stampings are metal stampings that form automotive components. They come in a wide variety, including shock absorber spring trays, spring seats, spring brackets, end caps, sealing caps, compression valve covers, compression valve sleeves, oil seal seats, bottom caps, dust caps, impellers, oil cylinders, lugs, and brackets. Some automotive stampings become auto parts directly after stamping, while others require further processing, such as welding, machining, or painting, before becoming auto parts. Machining includes stamping the parts. A stamping device is used to stamp the parts into a specific desired shape.

[0003] During the punching process of automotive parts, workers often manually hold the parts to perform punching operations, which is labor-intensive and poses a safety hazard. For example, a stamping device and a stamping method for automotive parts processing described in application number 202010404928.1 can replace the punch through a replacement mechanism. For the stamping of different parts, it is convenient to replace the punch and achieve the stamping forming of multiple parts. However, the number of punching heads is single. As the punching operation of parts continues, a single punching head is prone to accumulate a lot of heat, which has a negative impact on the service life of the punching head.

[0004] Based on the search of the above information, it can be seen that in the existing stamping process of automobile parts, due to the single number of stamping heads, it is easy to cause the defect of heat accumulation during continuous operation, and the parts to be stamped are often placed directly under the stamping head. During use, it is easy to cause personal injury due to misoperation. For this reason, a stamping mechanism for automobile parts and a method of use thereof are specially proposed, in which a position deviated from the position directly below the stamping head is used as a loading point. During stamping, the parts to be stamped are automatically moved to the position directly below the stamping head. While ensuring the stamping quality, two stamping heads are provided, which are operated alternately to avoid heat accumulation in the stamping heads. Summary of the Invention

[0066] As a preferred solution, when the lower die base 4 has a punching hole, the top of the inner cavity of the working box 1 is fixedly connected with a flow guide cover 103 used in conjunction with the lower die base 4, and the front of the working box 1 is provided with a discharge port 104 connected to the flow guide cover 103, and the front of the working box 1 is also provided with a waste box 105.

[0067] The advantages of Example 2 over Example 1 are that the positioning block 1006 lifts the parts to be stamped and the parts that have been stamped, thereby achieving the effect of convenient loading and unloading, and the arrangement of the air guide hood 103, the discharge port 104 and the waste box 105 provides convenient conditions for collecting the waste generated by punching.

[0068] A method for using a stamping mechanism for automobile parts, comprising the following steps:

[0069] S1. Place the parts to be stamped in the three positioning blocks 1006 above the assembly plate 501, control the stamping cylinder 301 to contract, and move the collaborative plate 302 from the highest point to the height A to be stamped. The collaborative plate 302 drives the inserting plate 303 and the positioning plate 304 to move downward, and the inserting plate 303 drives the movable slide 305 to squeeze one punching head 7 to move downward. At this time, the positioning plate 304 set on the front side limits the back of the other punching head 7. When the movable slide 305 descends, it squeezes the upper inclined surface of the triangular plate 903, so that the triangular plate 903 drives the squeezing plate 902 to compress the third spring 904, and the triangular plate 903 disengages from the square hole 307. The pin plate 704 is inserted into the square hole 307 under the action of the elastic member 703, completing the positioning of the movable slide 305 and the punching head 7.

[0070] S2. When the inserting plate 303 in S1 descends, the slotted supporting plate 1009 is driven to descend, and the fourth spring 1008 pulls the force-bearing plate 1007 to descend. The force-bearing plate 1007 drives the vertical plate 1001 through the L-shaped plate 1002 to make the rocker 1003 descend, and the rocker 1003 drives the supporting seat 1004 to descend. The supporting seat 1004 drives the connecting rod 1005 to make the positioning block 1006 sink into the slot 102. At this time, the parts to be stamped fall on the top of the working box 1, and the shifting cylinder 503 is started. The shifting cylinder 503 pushes the connecting plate to make the stepped slider 504 slide in the slide groove 101, and the assembly plate 501 drives the parts to be stamped to move to the top of the lower die base 4;

[0071] When the assembly plate 501 drives the part to be stamped to move to the top of the lower die base 4, the assembly plate 501 drives the teeth 505 to rotate the gear 8012 180 degrees. The gear 8012 drives the shaft 8011 to rotate the turntable 801. The turntable 801 drives the eccentric column 802 to squeeze the square frame 803. The square frame 803 pushes the slide plate 805 through the first spring 806 to drive the flat plate 807 to move backward. The flat plate 807 drives the L-shaped plate 808 to slide in the rear slide 602. During this process, the L-shaped plate 808 stretches the second spring 809.

[0072] S3, control the punching cylinder 301 to accelerate and contract, drive the movable slide 305 to make the punching head 7 punch the parts to be punched, and the punched waste falls into the guide cover 103, and is stored in the waste box 105 through the discharge port 104. Then control the punching cylinder 301 to extend and reset;

[0073] S4. During the extension and reset process of the punching cylinder 301, the punching cylinder 301 drives the cooperation plate 302 to move the inserting plate 303 upward, and the inserting plate 303 drives the movable slide 305 to move upward. When the movable slide 305 contacts the lower inclined surface of the triangular plate 903, the triangular plate 903 drives the extrusion plate 902 to compress the third spring 904. When the triangular plate 903 moves to the square hole 307, the third spring 904 resets, so that the triangular plate 903 is inserted into the square hole 307, and the pin plate 704 is pushed away from the square hole 307. At this time, the second spring 809 pulls the pulling plate 8010 to squeeze another punch head 7 from the front slide 601 to the movable slide 305, and squeezes the punch head 7 that has completed the punching into the rear slide 602.

[0074] S5, during the rising and resetting process of the inserting plate 303, the grooved supporting plate 1009 is driven to press the L-shaped plate 1002 upward, so that the positioning block 1006 moves upward to above the assembly plate 501, and the S1-S2 operation is repeated. During the process, the positioning plate 304 set on the rear side limits the front position of the punching head 7. When the assembly plate 501 drives the parts to be punched to move to just above the lower die base 4, the assembly plate 501 drives several teeth 505 to rotate the gear 8012 180 degrees in the opposite direction. The gear 8012 drives the rotating shaft 8011 to rotate the turntable 801. The turntable 801 drives the eccentric column 802 to squeeze the square frame 803. The box 803 stretches the first spring 806, and the first spring 806 squeezes the punching head 7 through the cooperation of the slide plate 805, the flat plate 807 and the L-shaped plate 808;
