Description

Technical Field

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

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] When processing holes in existing automobile parts, the part sheet is usually placed on a stamping machine, and the stamping die is used to extrude the sheet for stamping. The burrs generated by the stamping will remain at the bottom of the hole edge. When the operator picks up the part, the burrs remaining on the hole edge can easily scratch the operator, making it inconvenient to pick up the part. After the processing is completed, the operator needs to manually use a file to grind the hole edge, which is time-consuming and labor-intensive. The ground hole is easy to be gradually ground into an ellipse due to the different force points applied by the operator during the grinding process, resulting in reduced assembly accuracy of the parts and components, which may cause product quality problems in the assembled car. At the same time, the processed parts are stacked in the spare parts area for a long time, and the side walls of the round holes generated by the stamping can easily react with water vapor in the air, causing rust inside the round holes, affecting the quality of the parts. Therefore, the present application provides an automobile part stamping device to meet the needs. Summary of the invention

The filling needle 75 passes through the inner pipeline of the punch head 53. The punch head 53 presses the filling box 74 downward. By squeezing the oil, the oil enters the interior of the filling box 74 through the pipeline, enters the internal channel of the punch head 53 from the inside of the filling needle 75, and flows out from the drip hole 56. When the hydraulic cylinder 3 is reset, the punch head 53 moves upward, and the oil flowing out of the drip hole 56 adheres to the outer side of the punch head 53 and contacts the inside of the punch hole, so that an oil film is formed inside the punch hole to protect the processed surface from rust.

[0031] The working principle of the technical solution provided by the present invention is as follows: First, according to the processing drawing, rotate the lower template 57 of appropriate size, install the lower template 57 on the top of the workbench 2, align the lower template 57 with the punch head 52, place the plate to be processed on the sliding frame 11, align the pre-processed hole position with the lower template 57 and the punch head 52, start the hydraulic cylinder 3 through the control module (not marked in the figure) connected to the outside of the punch frame 4, so that the four groups of hydraulic cylinders 3 can be retracted downward at the same time, so that the punch frame 4 moves towards the direction close to the machine tool base 1 and the workbench 2, so that the mounting rod 51 drives the corresponding punch head 52 to punch the processed plate, and the lower plate at the bottom of the plate is The template 57 provides support for the sheet material, so that the hollow part of the lower template 57 is cut by the punch head 52. The auxiliary pressing block 54 corresponding to the mounting rod 51 is at the top of the sheet material. With the continuous downward pressure of the hydraulic cylinder 3, the spring 55 is squeezed. After the processing of the hole on the surface of the sheet material is completed, the control module is used to reset the hydraulic cylinder 3, driving the punch frame 4 to move upward, and the spring 55 is reset to provide a quick reset force for the punch head 52. At the same time, the auxiliary pressing block 54 is quickly pushed when the spring 55 is reset, so that the punch head 52 vibrates to avoid the waste generated by punching from being stuck inside the punch head 52.

[0032] Subsequently, the electric push rod 10 is started through the control module, so that the sliding frame 11 slides on the workbench 2 under the push of the electric push rod 10, so that the plate reaches between the buffer 9 and the second punch head 53, and the hydraulic cylinder 3 is controlled to start again, so that the four groups of hydraulic cylinders 3 can shrink downward at the same time, so that the mounting rod 51 drives the corresponding second punch head 53 to pass through the processed hole. As the punch frame 4 moves downward, the auxiliary pressure block 54 is close to the top of the punching hole of the plate. With the continuous downward pressure of the hydraulic cylinder 3, the auxiliary pressure block 54 squeezes the spring 1 55, and contacts the top surface of the filling box 74 through the end of the second punch head 53, so that the connecting rod 63 is forced to move downward. The fixing block 62 slides in the spiral groove of the mounting sleeve 61, so that the connecting rod 63 rotates during the downward movement. At the same time, the sliding block 65 slides inside the slide groove of the mounting plate 64 under the traction and guidance of the connecting plate 1 66 as it moves downward, so that the mounting frame 67 connected to the end of the connecting plate 1 66 moves to the edge of the hole close to the plate through the flipping of the connecting shaft, and the auxiliary pulley 68 performs auxiliary sliding on the bottom surface of the plate. The punch head 2 53 moves downward, and the filling needle 75 passes through the end hole of the punch head 2 53 and enters the interior of the punch head 2 53, so that the rubber block 530 at the end of the punch head 2 53 and the filling box are connected. The top of the mounting plate 64 contacts with the top of the mounting plate 64, and as it continues to move downward, the mounting plate 64 is pushed to move in the vertical direction. The sliding block 65 is subjected to the traction and guiding force of the downward movement of the end of the mounting plate 64, and slides toward the edge of the mounting plate 64 on the inner side of the slide groove of the mounting plate 64, so that the sliding block 65 pushes the mounting frame 67 to fold around the top bracket of the collecting tank 12 through the outer connecting plate 66 of the sliding block 65, and rotates toward the axial direction of the mounting plate 64, so that the deburring scraper 69 moves close to the edge of the hole of the plate, and the auxiliary pulley 68 performs auxiliary sliding on the bottom surface of the plate to prevent the bottom surface of the plate from being damaged by friction with the deburring scraper 69. The punch head 53 moves downward under the push of the punch head 53, and the connecting rod 63 enters the inner side of the installation sleeve 61 during the downward movement. The fixing block 62 at the end of the installation sleeve 61 slides in the spiral groove of the connecting rod 63, so that the installation sleeve 61 drives the turntable 13 to rotate inside the collecting tank 12, so that the four sets of mounting frames 67 drive the deburring scraper 69 to contact the edges of the burrs and debris generated by the downward punching. When the mounting frame 67 is driven by the connecting rod 63 to rotate, the deburring scraper 69 continuously scrapes the roots of the downward burrs generated by the punching, so as to avoid uneven grinding of the hole edge due to different forces applied by the operators when the operators manually grind the burrs, and select the hole processing accuracy.

[0033] When the punch head 53 moves downward, the outer wall of the punch head 53 contacts the contact block 82, squeezing the contact block 82 so that the contact block 82 rotates toward the inside of the mounting box 81. The elastic telescopic rod 83 contracts under force, and the side wall of the contact block 82 contacts the bottom end of the push rod 86, so that the push rod 86 pushes the piston plate 85 upward to move upward on the inside of the cleaning box 84, so that the cleaning fluid inside the cleaning box 84 is sprayed to the bottom end of the punched processed hole through the spray head 87, preventing burrs and debris from adhering to the edge of the hole, thereby improving the cleanliness of the workpiece. At the same time, the waterproof ring 88 located on the outside of the punch head 53 can prevent the spray head 87 from adhering to the surface of the punch head 53 when spraying the cleaning fluid, and the waste liquid finally drips into the collection tank 12 for collection.

[0034] When the punch head 53 moves downward, the end of the punch head 53 contacts the top of the filling box 74, and the two rubber block blocks 530 are opened by the extrusion force of the filling needle 75. The filling needle 75 passes through the inner pipeline of the punch head 53, and the punch head 53 presses the filling box 74 downward, causing the piston plate 1 72 to move downward. The spring 2 73 is compressed by the force, and the oil enters the interior of the filling box 74 through the pipeline, enters the internal channel of the punch head 53 from the inside of the filling needle 75, and flows out from the drip hole 56. When the hydraulic cylinder 3 is reset, the punch head 53 moves upward, and the oil flowing out of the drip hole 56 adheres to the outer side of the punch head 53 and contacts the inside of the punch hole, so that an oil film is formed inside the punch hole to protect the processed surface from rust.
