Technical Field

[0001] This utility model relates to a punching die, and more particularly to a punching die for the production of automotive parts in the field of die technology. Background Technology

[0002] Punching is a common machining process in the production of automotive parts, used to create the required holes in the parts.

[0003] Chinese patent CN103752681B discloses a punching die. This punching die can meet the needs of manufacturers, has wide applicability, and is suitable for mass production to improve production efficiency and reduce production costs. Due to its excellent performance and wide range of applications, this patented punching die has good application prospects.

[0004] Chinese patent CN221620526U discloses a punching die for automotive parts production. When the equipment is started, the drive motor starts, causing the drive shaft to rotate, which in turn rotates the drive threaded rod, causing the punching cutter to slide. This, in turn, causes the driven threaded rod to rotate, and the slider to slide below the punching cutter, making the equipment easier to operate. This technical solution solves the problems of cumbersome operation and high scrap rate in existing technologies.

[0005] Current punching devices lack a structure for timely handling of waste materials, resulting in waste materials getting stuck in the die cavity and not being cleared in time. When the punch descends, it collides with the waste materials, which not only affects the punching quality but also damages the mold and equipment. Utility Model Content

[0006] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the current punching device does not have a structure for timely handling of waste materials, which causes waste materials to get stuck in the die hole and not be cleaned in time. When the punch moves down, it collides with the waste materials, which not only affects the punching quality, but also causes damage to the mold and equipment.

[0007] To solve the above problems, this utility model provides a punching die for automobile parts production, including a device body of a working platform. A hydraulic cylinder is fixedly connected to the top of the device body, and an upper die is connected to the output end of the hydraulic cylinder via a telescopic rod. A punching head is fixedly connected to the bottom end of the upper die. A discharge port is opened on the working platform, and an inner groove communicating with the discharge port is opened on the side end of the device body. A support column is fixedly connected to the inner groove, and a lower die is fixedly connected to the top of the support column via multiple support frames. A punching hole is opened in the upper middle part of the lower die. A conical block corresponding to the punching hole is fixedly connected to the top of the support column, and the tip of the conical block is located inside the punching hole. A baffle is fixedly connected to the side of the discharge port on the working platform, and an air blowing port is installed on the inner wall of the baffle. A magnetic frame is fixedly connected to the device body directly above the baffle. A frame plate is fixedly connected to the bottom end of the magnetic frame. A dust cover is fixedly connected to the end of the frame plate away from the magnetic frame. A magnetic sheet is fixedly connected to the top of the baffle, and the dust cover attracts the magnetic sheet and the magnetic frame respectively.

[0008] In the aforementioned punching die, a dust cover that is easy to install and remove can prevent dust without affecting loading and unloading. During processing, the blower can be used to clean up dust and debris on the lower die in a timely manner.

[0009] As a further supplement to this application, an annular air vent is installed at the bottom of the lower mold on the outer ring of the punch, a blower is installed inside the device body, and the blower output port is connected to the air vent and the upper interface of the annular air vent through pipes respectively.

[0010] As a further supplement to this application, two symmetrical receiving boxes are placed in the inner tank, and extension grooves are symmetrically opened at both ends of the inner tank, and the depth of the extension grooves is greater than half the length of the receiving boxes.

[0011] As a further supplement to this application, a filter screen is detachably connected inside the receiving box, and support legs are fixedly connected to the four corners of the bottom of the filter screen.

[0012] As a further supplement to this application, the receiving box is fixedly connected with a slot corresponding to the support leg, and the support leg engages with the slot.

[0013] As a further supplement to this application, a lower buffer pad is fixedly connected to the four corners of the top of the lower mold, and an upper buffer pad corresponding to the lower buffer pad is fixedly connected to the bottom of the upper mold.

[0014] As a further supplement to this application, a controller for controlling the hydraulic cylinder and the blower is fixedly connected to the main body of the device.

[0015] In summary, after aligning the car part on the lower mold, pull down the frame plate to attract and fix it with the magnetic plate on the top of the baffle. At this time, the dust cover is unfolded and covers the area around the lower mold. Then, the controller activates the hydraulic cylinder to drive the upper mold and the stamping head to press down, stamping the car part. The waste generated during stamping falls from the punch hole onto the conical block, and then falls down the inclined plane through the opening between multiple support frames into the inner groove for discharge. At the same time, the controller activates the blower, which blows air onto the lower mold through the air outlet on the inner wall of the baffle, blowing the debris and powder generated during stamping into the discharge port and into the inner groove. The unfolded dust cover forms a closed space, effectively preventing the powder from scattering. After the stamping operation is completed, when loading materials again, simply open the dust cover to quickly load materials and continue the operation. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-5This invention discloses a punching die for automotive parts production, comprising a device body 1 of a working platform, a hydraulic cylinder 15 fixedly connected to the top of the device body 1, an upper die 4 connected to the output end of the hydraulic cylinder 15 via a telescopic rod, a punching head 6 fixedly connected to the bottom of the upper die 4, a discharge port 22 provided on the working platform, an inner groove 11 communicating with the discharge port 22 provided on the side of the device body 1, a support column 23 fixedly connected within the inner groove 11, a lower die 2 fixedly connected to the top of the support column 23 via multiple support brackets 16, and a punching hole 3 provided in the upper middle part of the lower die 2. A conical block 17 corresponding to the punch 3 is fixedly connected to the top of the support column 23, and the tip of the conical block 17 is located inside the punch 3. A baffle 7 is fixedly connected to the side of the discharge port 22 on the worktable. An air blowing port 20 is installed on the inner wall of the baffle 7. A magnetic frame 13 is fixedly connected to the device body 1 directly above the baffle 7. A frame plate 9 is fixedly connected to the bottom of the magnetic frame 13. A dust cover 10 is fixedly connected to the end of the frame plate 9 away from the magnetic frame 13. A magnetic sheet 8 is fixedly connected to the top of the baffle 7, and the dust cover 10 attracts the magnetic sheet 8 and the magnetic frame 13 respectively.

[0027] The bottom of the lower mold 2 is located on the outer ring of the punch 3 and an annular air vent 18 is installed. A blower is installed inside the device body 1, and the blower output port is connected to the air vent 20 and the annular air vent 18 through pipes respectively. The device body 1 is fixedly connected to the control cylinder 15 and the blower controller.

[0028] The blower uses existing technology, and those skilled in the art should select a suitable blower from the existing technology for installation, such as the explosion-proof standard GB12476.1-2013.

[0029] Working principle: After aligning the car part on the lower mold 2, the frame plate 9 is pulled down and attracted to the magnetic plate 8 on the top of the baffle 7. At this time, the dust cover 10 is unfolded and covers the lower mold 2. At this time, the controller opens the oil cylinder 15 to drive the upper mold 4 to drive the stamping head 6 to press down and stamp the car part. The waste generated during stamping falls from the punch 3 onto the conical block 17, and then falls down the inclined plane from the opening between multiple support frames 16 into the inner groove 11 for discharge. At the same time, the controller opens the blower and blows air onto the lower mold 2 through the air outlet 20 on the inner wall of the baffle 7, blowing the debris and powder generated during stamping into the discharge port 22 and into the inner groove 11. The unfolded dust cover 10 forms a closed space, effectively preventing the powder from scattering. After the stamping operation is completed, when loading again, simply open the dust cover 10 to quickly load the material and continue the operation.

[0030] This utility model, by setting up a dust cover 10 that is easy to install and remove, can not only prevent dust but also not affect the loading and unloading of materials. During processing, the air blower 20 can be used to clean up the dust and debris on the lower mold 2 in a timely manner.

[0031] Second implementation method:

[0032] Figure 3 and Figure 6 The inner groove 11 contains two symmetrical receiving boxes 12. The inner groove 11 has symmetrical extension grooves at both ends, and the depth of the extension grooves is greater than half the length of the receiving box 12. A filter screen 21 is detachably connected inside the receiving box 12. Support legs 19 are fixedly connected to the four corners of the bottom end of the filter screen 21. The receiving box 12 has a corresponding slot for the support leg 19, and the support leg 19 engages with the slot. A lower buffer pad 5 is fixedly connected to the four corners of the top end of the lower mold 2. An upper buffer pad 14 corresponding to the lower buffer pad 5 is fixedly connected to the bottom end of the upper mold 4.

[0033] Working principle: When the upper mold 4 moves the stamping head 6 to stamp the car parts, when the stamping head 6 presses into the punch hole 3, the upper buffer pad 14 and the lower buffer pad 5 collide, which can reduce the impact vibration between the upper mold 4 and the lower mold 2. The waste material and debris in the stamping process fall from the punch hole 3 into the bottom conical block 17 and then into the receiving box 12. At the same time, the blower is turned on, so that the debris attached to the surface of the conical block 17 is blown into the receiving box 12 through the annular air vent 18. Similarly, the air vent 20 blows the powder and debris on the surface of the lower mold 2 into the receiving box 12. The waste material and debris fall into the filter screen 21 in the receiving box 12 for filtration, which can separate large particles from powder. After the stamping is completed, the receiving box 12 can be moved into the extension groove, and the receiving box 12 can be taken out from the inner groove 11. Finally, the support leg 19 at the bottom of the filter screen 21 can be pulled out from the slot to disassemble the filter screen 21.

[0034] In this invention, two receiving boxes 12 corresponding to the discharge port 22 are placed in the inner groove 11 to collect the debris and powder generated during stamping. At the same time, the debris and powder can be separated through the internal filter screen 21. Furthermore, an annular air vent 18 is provided at the bottom of the punch 3 to prevent the accumulation of powder and debris on the conical block 17 from affecting the discharge.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
