Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for processing a trunk cover of an automobile. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts.

[0003] According to the patent application number CN202223437052.4, after the stamping material is placed on the lower mold installed on the top surface of the equipment base, the hydraulic rod installed on the beam plate is started to push the upper plate downward, so that the lower mold under the upper plate fits with the upper mold to complete the stamping. During the descent of the upper plate, the safety ring installed on the upper plate is slidably connected with the support to ensure that the upper and lower molds do not deviate from each other during the stamping process. At the same time, during the downward movement of the upper plate, the metal sheet A installed on the top surface of the upper plate will fit with the metal sheet B installed on the bottom surface of the beam plate. Separation, so that the motor rotates clockwise, driving the bidirectional threaded rod to rotate, so that the threaded blocks installed on the threads of the two sections of the bidirectional threaded rod in different directions move correspondingly, so that the two protective covers on the outer side of the lower die are close to each other to form a circular ring to block the flying waste chips. After the stamping is completed, the hydraulic rod drives the upper plate to move up. When the metal sheet A and the metal sheet B fit together, the motor rotates counterclockwise, and the two protective covers are separated, which is convenient for the operator to take and put materials, and can prevent the waste chips generated during stamping from splashing onto the operator, making the use of the stamping die safer;

[0004] In the above patent, a lot of waste will be generated when the trunk lid is stamped with the stamping die, which needs to be cleaned manually. In the process of cleaning, the waste is likely to be scattered all over the die, making it difficult to collect and process it in a centralized manner. The above-mentioned setting of the safety ring and the pillar can ensure that the upper and lower dies do not deviate from each other during the stamping process. However, the long-term sliding contact between the pillar and the safety ring is prone to wear, resulting in obstruction of the sliding of the safety ring, thereby affecting the subsequent alignment and fit of the upper and lower dies. Therefore, in view of the above-mentioned deficiencies, the present invention makes the following improvements. Summary of the invention

[0033] The trunk cover to be stamped is placed between the upper die base 3 and the lower die base 2, and the extended end of the hydraulic cylinder 5 is controlled to drive the push plate 7 to move downward. At this time, the upper die base 3 can be driven to move downward along the inner wall of the enclosure 4 under the action of the vertical rod, so that the trunk cover is stamped inside the die cavity, and the waste generated after stamping is left inside the die cavity. At this time, the upper die base 3 is controlled to rise to a certain height such as Figure 2 As shown, this height can close the top surface of the enclosure 4, start the external blowing device, and the gas enters the inside of the annular tube 61 through the conduit, and the gas inside the annular tube 61 enters the inside of the enclosure 4 through the air inlet pipe 62 and the inclined hole;

As the middle plate 615 moves upward, the two movable plates 65 can be driven to rotate along it, and then the movable plate 65 can drive the guide block 614 to slide along the surface of the guide rail 613 until a triangular inclined state is presented between the two movable plates 65. At this time, the waste on the movable plate 65 falls and is discharged into the interior of the receiving box 617. After all the waste is discharged, the movable plate 65 is controlled to return to its initial state in the same way, so that the top surface of the receiving box 617 is in a closed state. The above operation can avoid the problem that the waste inside the receiving box 617 is blown up again and scattered into the mold cavity during subsequent cleaning. When the waste inside the receiving box 617 is collected to a certain amount, the personnel can take the receiving box 617 out of the collection box 64.

[0036] Embodiment 2

[0037] Based on Example 1, please refer to Figure 1 as well as Figures 5 to 7 The specific improvements are as follows:

[0038] A sleeve 8 is fixedly arranged inside the push plate 7, and a column 10 is arranged inside the sleeve 8. A lubrication protection mechanism 9 is arranged inside the sleeve 8. The bottom end of the column 10 is fixedly connected to the top surface of the support platform 1 through a fixing plate 11. The lubrication protection mechanism 9 includes an oil storage box 92 fixedly arranged on the top of the column 10. A first telescopic tube 91 is fixedly arranged between the bottom end of the sleeve 8 and the top surface of the fixing plate 11, and the first telescopic tube 91 is sleeved on the surface of the column 10. A second telescopic tube 910 is connected between the top surface of the oil storage box 92 and the top surface of the inner wall of the sleeve 8. The lubricating oil enters the interior of the oil storage box 92 through the second telescopic tube 910 for storage. A sealing cover is arranged on the top of the second telescopic tube 910. A lubrication wheel 93 is arranged on the surface of the oil storage box 92 through a U-shaped rod rotation, and the surface of the lubrication wheel 93 contacts the inner wall of the sleeve 8. An oil outlet groove is provided, and the interior of the oil outlet groove contacts the surface of the lubrication wheel 93 through an oil-absorbing sponge 94. A control unit is provided inside the oil storage box 92, and the control unit includes a rotating rod 95 rotatably arranged inside the oil storage box 92, and the bottom end of the rotating rod 95 sequentially penetrates the column 10 and the fixed plate 11 and extends to the bottom surface of the fixed plate 11. A sealing ring is provided on the bottom surface of the oil storage box 92 and on the surface of the rotating rod 95. The bottom end of the rotating rod 95 is rotatably connected to the top surface of the support platform 1 through a bearing. The surface of the rotating rod 95 located inside the oil storage box 92 is fixedly provided with an annular sealing plate 96 through a short rod, and the annular sealing plate 96 is adapted to the oil leakage groove. A gear 97 is fixedly provided on the surface of the rotating rod 95.

[0039] The first telescopic tube 91 can protect the surface of the column 10 to prevent dust from adhering, and the lubricating oil is pre-transported to the interior of the oil storage box 92 through the second telescopic tube 910 for storage. A large amount of lubricating oil is stored in the oil storage box 92. When the push plate 7 moves up and down, the sleeve 8 moves up and down along the surface of the lubricating wheel 93, and the electric slide rail 98 is controlled to start. The electric slide rail 98 drives the toothed plate 99 to move forward and backward through the connecting block. During the movement of the toothed plate 99 forward and backward, the rotating rod 95 can be driven to rotate through the gear 97, and the rotating rod 95 drives the annular sealing plate 96 to rotate synchronously through the short rod, so that the oil outlet groove can be opened. At this time, the lubricating oil inside the oil storage box 92 enters the interior of the oil absorption sponge 94 from the oil outlet groove. The oil absorption sponge 94 absorbs lubricating oil. Therefore, when the lubricating wheel 93 contacts the oil absorption sponge 94, the lubricating oil can be transferred to the inner wall of the sleeve 8, thereby realizing the lubrication of the sleeve 8, reducing wear, and making the subsequent upper die base 3 and the lower die base 2 aligned and fit.
