Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, specifically to an automatic feeding device for automotive continuous stamping dies. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the desired shape and size. Stamping and forging both belong to plastic processing (or pressure processing), and are collectively referred to as forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

[0003] In the existing technology, in order to save time, continuous stamping dies are mostly used in the stamping production of stamped parts in automobiles. However, during continuous stamping production, there will be waste material generated by stamping. The waste material generated by punching can easily get stuck in the hole of the die due to the deformation of the workpiece itself. The current solution is to open a hole with a larger diameter below the punching hole of the lower die base. However, when using this method, the corresponding stamping rod of the upper die base needs to be set to be longer. In this way, the stamping rod is prone to bending and damage. Alternatively, the punching depth of the lower die base is too short. In this way, the punching position of the lower die base is prone to deformation during use, which is inconvenient. Summary of the Invention

In the stamping production process of automotive stamped parts, continuous stamping dies are mostly used to save time. However, during continuous stamping production, there will be waste material generated by stamping. The waste material generated by punching is prone to getting stuck in the die holes due to the deformation of the workpiece itself. The current solution is mostly to open a hole with a larger diameter below the punching hole of the lower die base.

The interior of the installation groove is provided with a material storage drawer, and both sides of the material storage drawer are fixedly connected with connecting slide plates, which are slidably connected to the sliding grooves.

[0007] Preferably, a handle is fixedly connected to one side of the storage drawer, and a slot is provided at the lower end of the interior of the storage drawer, into which a magnetic plate is inserted.

[0008] Preferably, a second handle is fixedly connected to one side of the magnetic suction plate, an extension sleeve is fixedly connected to the upper end of the bottom frame, and an inner through groove is opened through the middle of the connecting frame, the inner through groove being inserted into the extension sleeve.

[0009] Preferably, the upper end of the extension sleeve is provided with a No. 3 slot, and a No. 2 rubber strip is engaged inside the No. 3 slot.

[0010] Preferably, a second slot is provided on one side of the bottom frame, and a side limiting rod is provided on one side of the second slot, and the side limiting rod is fixedly connected to the bottom frame.

[0011] Preferably, a connecting groove is provided on one side of the storage drawer, and a side sleeve is fixedly connected to one side of the connecting groove. The side sleeve is inserted into the second slot. The outer edge of one side of the side sleeve is designed with an inclination. A transparent plate is fixedly connected inside the connecting groove.

[0012] Preferably, each of the four corners of the connecting frame has an insertion hole, a guide post is inserted into the insertion hole, and a mounting base is fixedly connected to the outer surface of the guide post. The mounting base is fixedly connected to the connecting frame.

[0013] Preferably, the output end of the vacuum pump is fixedly connected to a connecting pipe, and one end of the connecting pipe has a threaded hole.

[0014] Preferably, a mounting plate is provided on one side of the connecting frame, a magnetic block is fixedly connected inside the mounting plate, a limiting bracket is rotatably connected to one side of the mounting plate, a rubber strip is fixedly connected inside the limiting bracket, and the inside of the limiting bracket is engaged with one end of the connecting tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting up a base frame and a vacuum pump, in conjunction with a guide sleeve, the vacuum pump extracts the gas inside the base frame during use, creating a negative pressure state inside the base frame. In this way, during continuous stamping, when punching the workpiece, atmospheric pressure and airflow can drive the stamping waste into the interior of the base frame, automatically discharging the waste. This facilitates waste collection and, through negative pressure, allows the workpiece to be adsorbed onto the lower die during stamping, ensuring the stability of workpiece processing. This increases the production qualification rate of automotive workpieces, ensuring the quality and efficiency of automobile production. By setting the positions of the guide sleeve and the connection port, it is ensured that the stamping waste falls into the base frame and does not block the connection port.

[0016] 2. In this invention, the storage drawer is designed for easy access via a pull-out mechanism. Collected automotive stamping waste falls within the bottom frame, facilitating its removal. A magnetic suction plate holds the waste to the bottom of the drawer, ensuring its stability within the frame and preventing movement, thus increasing stability. The pull-out design of the magnetic suction plate allows for easy removal of the waste by simply pulling it out, leaving it in the drawer for later emptying. This facilitates collection and use. The design of the slot and side sleeve allows one end of the storage drawer to be inserted into the second slot, increasing the stability of the storage drawer. The side limiting rod reinforces one side of the bottom frame, ensuring a connection between the storage drawer and the bottom frame. The transparent plate allows observation of the waste material inside the storage drawer. The extension sleeve and the second rubber strip enhance the seal between the bottom frame and the lower mold base. The inner through groove and extension sleeve restrict the extension sleeve to the connecting frame, facilitating subsequent installation of the bottom frame and the connecting frame.

[0017] 3. In this invention, the connection area between the guide post and the connecting frame is increased by setting the insertion hole, thereby increasing the stability of use. By setting the connecting tube, together with the limiting card holder and magnetic block, the mounting plate is installed at the position that needs to be cooled according to the actual use situation, and one end of the connecting tube is aligned with the area that needs to be cooled. In this way, on the one hand, the discharge of waste material during the stamping of automotive parts can be guaranteed, and on the other hand, it can facilitate the cooling of the heat-generating area. Moreover, it can be set arbitrarily according to needs. The setting of the first rubber strip is used to increase the friction between it and the connecting tube, thereby increasing the stability of use. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Refer to Figure 1 - Figure 9 As shown: An automatic material discharge device for automotive continuous stamping dies includes a die mechanism 1. The die mechanism 1 includes a connecting frame 11. A self-discharging mechanism 2 is provided at the lower end of the connecting frame 11. The self-discharging mechanism 2 includes a base frame 21, which is fixedly connected to the connecting frame 11. Support legs 12 are fixedly connected to the four corners of the lower end of the connecting frame 11. A vacuum pump 19 is fixedly connected to one side of one of the support legs 12. A connection port 216 is fixedly connected to one side of the base frame 21, and the connection port 216 is connected to the input end of the vacuum pump 19. The upper end of the connecting frame 11 is fixedly connected to the lower mold base 14 through the set pipe. The lower mold base 14 has a punching hole 15 inside. The lower end of the punching hole 15 has a first slot 116. The first slot 116 is fitted with a locking block 27. The locking block 27 is fixedly connected with a guide sleeve 26. The diameter of the guide sleeve 26 is larger than the diameter of the punching hole 15. The shape of the guide sleeve 26 and the locking block 27 are set together according to the shape of the punching hole 15. The connection port 216 is set above the middle part of the bottom frame 21.

[0022] In this invention, by setting up the bottom frame 21 and the vacuum pump 19, in conjunction with the guide sleeve 26, during use, the vacuum pump 19 extracts the gas inside the bottom frame 21, making the bottom frame 21 a negative pressure state. In this way, during the continuous stamping process, when punching the workpiece, the waste generated during stamping can be sucked into the bottom frame 21 by atmospheric pressure and airflow. In this way, the waste is automatically discharged, which facilitates the collection of waste and allows the workpiece to be adsorbed onto the lower die base 14 during stamping by the negative pressure, ensuring the stability of workpiece processing. This increases the production qualification rate of automobile workpieces, thereby ensuring the quality and efficiency of automobile production. By setting the positions of the guide sleeve 26 and the connection port 216, it can be ensured that the waste generated during stamping falls into the bottom frame 21 and does not block the connection port 216.

[0023] Example 2: Figure 1 - Figure 8 As shown, the lower end of the base frame 21 has a mounting groove 213, and both sides of the mounting groove 213 have sliding grooves 214. A storage drawer 22 is installed inside the mounting groove 213. Connecting slide plates 215 are fixedly connected to both sides of the storage drawer 22, and the connecting slide plates 215 are slidably connected to the sliding grooves 214. A first handle 23 is fixedly connected to one side of the storage drawer 22. A slot 29 is opened at the lower end of the storage drawer 22, and a magnetic plate 220 is inserted into the slot 29. A second handle 28 is fixedly connected to one side of the magnetic plate 220. An extension sleeve 210 is fixedly connected to the upper end of the base frame 21. An inner... The inner through groove 110 is inserted into the extension sleeve 210. The upper end of the extension sleeve 210 is provided with a third slot 217. A second rubber strip 211 is inserted into the inner part of the third slot 217. A second slot 25 is provided on one side of the bottom frame 21. A side limiting rod 24 is provided on one side of the second slot 25. The side limiting rod 24 is fixedly connected to the bottom frame 21. A connecting groove 219 is provided on one side of the storage drawer 22. A side sleeve 218 is fixedly connected to one side of the connecting groove 219. The side sleeve 218 is inserted into the second slot 25. The outer edge of one side of the side sleeve 218 is designed with an inclination. A transparent plate 212 is fixedly connected inside the connecting groove 219.

[0024] In this invention, the storage drawer 22 is designed for use via a pull-out mechanism. Collected automotive stamping waste falls into the bottom frame 21, facilitating its removal. The magnetic suction plate 220 holds the waste at the bottom of the drawer 22, ensuring its stability within the bottom frame 21 and preventing movement, thus increasing stability. The pull-out design of the magnetic suction plate 220 allows the waste to be easily removed by simply pulling it out, leaving it in the drawer 22 for later emptying. The second card slot 25 and the side card sleeve 218 further enhance the storage capacity. One end of the storage drawer 22 is inserted into the second slot 25 to increase the stability of the storage drawer 22. The side limit rod 24 is used to reinforce one side of the bottom frame 21 to ensure that the storage drawer 22 and the bottom frame 21 can be connected. The transparent plate 212 allows observation of the waste inside the storage drawer 22. The extension sleeve 210 and the second rubber strip 211 increase the sealing between the bottom frame 21 and the lower mold base 14. The inner through groove 110 and the extension sleeve 210 can restrict the extension sleeve 210 to the connecting frame 11 to facilitate the subsequent installation of the bottom frame 21 and the connecting frame 11.

[0025] Example 3: According to Figure 1 - Figure 5 As shown, each of the four corners of the connecting frame 11 has an insertion hole 112. A guide post 13 is inserted into the insertion hole 112. A mounting base 113 is fixedly connected to the outer surface of the guide post 13. The mounting base 113 is fixedly connected to the connecting frame 11. The output end of the vacuum pump 19 is fixedly connected to a connecting pipe 16. One end of the connecting pipe 16 has a threaded hole 111. A mounting plate 18 is provided on one side of the connecting frame 11. A magnetic block 114 is fixedly connected inside the mounting plate 18. A limiting bracket 17 is rotatably connected to one side of the mounting plate 18. A rubber strip 115 is fixedly connected inside the limiting bracket 17. The inside of the limiting bracket 17 is engaged with one end of the connecting pipe 16. The threaded hole 111 is used to install different ends according to the heat dissipation area.

[0026] In this invention, the connection area between the guide post 13 and the connecting frame 11 is increased by setting the insertion hole 112, thereby increasing the stability of use. By setting the connecting tube 16, together with the limiting card holder 17 and the magnetic block 114, the mounting plate 18 is installed at the position that needs to be cooled according to the actual use situation, and one end of the connecting tube 16 is aligned with the area that needs to be cooled. In this way, on the one hand, the discharge of waste material during the stamping of automotive parts can be guaranteed, and on the other hand, the cooling of the heat-generating area can be facilitated. Moreover, it can be set arbitrarily according to needs. The setting of the first rubber strip 115 is used to increase the friction between it and the connecting tube 16, thereby increasing the stability of use.

[0027] The usage and working principle of this device are as follows: When continuously stamping automotive parts, the workpiece to be processed is placed above the lower die base 14. The upper die base stamps the workpiece, causing it to deform. The workpiece is then transported by the feeding mechanism and gradually stamped to form the desired part. During this process, the vacuum pump 19 is turned on, creating a negative pressure inside the bottom frame 21. Air enters the punching hole 15, sucking in the waste material generated during stamping. The waste material is discharged into the bottom frame 21 and falls into the storage drawer 22 through the guide sleeve 26. The waste material is attracted by the magnetic suction plate 220. The amount of waste material stored in the storage drawer 22 can be observed through the transparent plate 212. When a certain amount of waste material accumulates, the first handle 23 is held to pull out the storage drawer 22. Then, the second handle 28 is held to pull out the magnetic suction plate 220. Finally, the waste material in the storage drawer 22 is poured into the recycling box. This method is used for continuous stamping. The processed parts are then processed in subsequent steps for use in automobile production.
