Description

Technical Field

[0001] This application relates to the field of material ejection mechanisms, and more specifically, to a material ejection mechanism and a stamping device. 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 of the required shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet metal to deformation force in the die, thereby obtaining product parts with certain shapes, sizes, and properties. When stamping steel plates to deform them into the required shape, the steel plates are pressed and formed in the bottom forming die. After the steel plates are stamped, they need to be manually removed from the stamping die. Because the steel plates are stuck in the stamping groove, the removal process is not convenient. Therefore, we propose a material ejection mechanism and stamping equipment. Utility Model Content

[0003] To overcome the above deficiencies, this application provides a material ejection mechanism and a stamping device, which aims to improve the problem of the inconvenience of removing steel plates from the stamping groove.

[0004] In a first aspect, embodiments of this application provide a material ejection mechanism, including a platform, a base mounted on the top of the platform, a forming seat and a lifting mechanism mounted on the base, a forming groove opened on the top of the forming seat, the lifting mechanism slidingly penetrating the bottom of the forming groove, and a top plate mounted on its top, and a pushing mechanism also mounted on the base.

[0005] In one specific implementation, the lifting mechanism includes a threaded rod with a lifting tube threaded onto it. The lifting tube slides through the bottom of the forming groove, and the top plate is fixedly connected to the top of the lifting tube.

[0006] In one specific implementation, a receiving groove is provided at the bottom of the forming groove, and the top plate is placed in the receiving groove.

[0007] In one specific implementation, the lifting mechanism further includes a lifting plate threaded onto the threaded rod, and a plurality of lifting rods are connected to the lifting plate. The plurality of lifting rods slide through the bottom of the forming groove, and the tops of the plurality of lifting rods are fixedly connected to the bottom of the top plate.

[0008] In one specific implementation, a drive rod rotatably passes through the side wall of the seat, and the drive rod is connected to the threaded rod in a driving connection.

[0009] In one specific implementation, a screw is fixedly connected to the bottom of the lifting rod, the screw slides through the lifting plate, and a nut is also connected thereto.

[0010] In one specific implementation, the pushing mechanism includes an electric push rod mounted on the top of the forming seat, and the output shaft of the electric push rod is connected to a push plate.

[0011] Secondly, this application also provides a stamping device, including...

[0012] The aforementioned material return mechanism.

[0013] The beneficial effects of this application are as follows: By installing a forming seat on the base, and opening a forming groove for stamping on the top of the forming seat, a lifting mechanism is installed on the base, and a top plate is connected to the top of the lifting mechanism. The top plate is located in the receiving groove at the bottom of the forming groove. After the steel plate is stamped, the lifting mechanism drives the top plate to move upward, pushing the steel plate out of the forming groove. Then, the pushing mechanism pushes the steel plate to one side of the forming seat, making it easy to remove the formed steel plate. By fixing a lifting pipe and a lifting rod to the bottom of the top plate, the lifting pipe can be removed from the threaded rod, and a screw is installed at the bottom of the lifting rod. The screw passes through the lifting plate and is connected to the screw, which facilitates the disassembly and assembly of the top plate. Attached Figure Description

Detailed Implementation

[0021] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0022] Please see Figure 1-5 This application provides a material ejection mechanism, including a platform 10, a base 20 mounted on the top of the platform 10, a forming base 30 and a lifting mechanism 40 mounted on the base 20, a forming groove 50 opened on the top of the forming base 30, the lifting mechanism 40 slidingly passing through the bottom of the forming groove 50, and a top plate 60 mounted on its top, and a pushing mechanism 70 also mounted on the base 20. Specifically, the base 20 is U-shaped, the forming base 30 and the base 20 are detachably connected, and the connection structure is an existing bolt connection structure. The steel plate is placed on the forming base 30 and located in the forming groove 50. Then, the steel plate is stamped and formed by the stamping mechanism. After the stamping is completed, the lifting mechanism 40 drives the top plate 60 to move upward, so that the top plate 60 pushes the steel plate out of the forming groove 50. Then, the pushing mechanism 70 pushes the steel plate to one side of the forming groove 50 to facilitate the removal of the steel plate.

[0023] See Figure 2 and 5 The lifting mechanism 40 includes a threaded rod 410, on which a lifting tube 420 is threadedly sleeved. The lifting tube 420 slides through the bottom of the forming groove 50. The top plate 60 is fixedly connected to the top of the lifting tube 420. The bottom of the forming groove 50 has a receiving groove 510. The top plate 60 is placed in the receiving groove 510. When set up, the bottom of the forming seat 30 has a first through hole. The bottom of the first through hole is connected to the bottom of the receiving groove 510. The lifting tube 420 is set through the first through hole. The top plate 60 is placed in the receiving groove 510. The top of the top plate 60 is flush with the bottom of the receiving groove 510. The bottom of the lifting tube 420 has a threaded hole that matches the threaded rod 410, so that the threaded rod 410 drives the lifting tube 420 to move.

[0024] See Figure 4 and 5The lifting mechanism 40 also includes a lifting plate 430 threaded onto the threaded rod 410. Several lifting rods 440 are connected to the lifting plate 430. The lifting rods 440 slide through the bottom of the forming groove 50, and the tops of the lifting rods 440 are fixedly connected to the bottom of the top plate 60. In a specific configuration, the bottom of the forming seat 30 is provided with several second through holes, and the tops of the several second through holes are connected to the bottom of the receiving groove 510. The lifting rods 440 pass through the several second through holes respectively. The lifting plate 430 is provided with threaded holes that are compatible with the threaded rod 410, so that when the threaded rod 410 rotates, it can drive the lifting plate 430 to move.

[0025] See Figure 2 A drive rod 210 is rotatably inserted through the side wall of the seat 20. The drive rod 210 is connected to the threaded rod 410. When set up, a first bevel gear is fixedly installed at one end of the drive rod 210 and a rotating handle is fixedly installed at the other end. A second bevel gear is fixedly sleeved on the threaded rod 410. The first bevel gear and the second bevel gear are meshed. By rotating the drive rod 210 through the rotating handle, the threaded rod 410 can be rotated.

[0026] See Figure 4 and 5 The bottom of the lifting rod 440 is fixedly connected to a screw 80, which slides through the lifting plate 430 and is also connected to a nut 810. It should be noted that several through holes are opened on the lifting plate 430, and several screws 80 pass through several through holes respectively. At the same time, the bottom of the lifting rod 440 is in contact with the top of the lifting plate 430, and the nut 810 is connected to the screw 80, so that the bottom of the lifting rod 440 can be fixedly installed on the lifting plate 430.

[0027] See Figure 5 The pushing mechanism 70 includes an electric push rod 710 mounted on the top of the forming seat 30. The output shaft of the electric push rod 710 is connected to a push plate 720. Specifically, the electric push rod 710 has a conventional mounting structure. The electric push rod 710 drives the push plate 720 to move horizontally, which can push the steel plate to one side of the forming seat 30 to facilitate the removal of the formed steel plate.

[0028] See Figure 1 A stamping device, comprising

[0029] The aforementioned ejection mechanism and support are fixedly installed on the top of the platform 10. A hydraulic cylinder assembly is also installed on the support 10. The output shaft of the hydraulic cylinder assembly is connected to the mold base. A stamping block is installed at the bottom of the mold base. The stamping block is correspondingly set with the forming groove 50 on the top of the forming seat 30. The hydraulic cylinder assembly drives the mold base to move downward, causing the mold base to drive the stamping block to move downward, thereby stamping the steel plate into the forming groove 50 for forming.

[0030] When using this ejection mechanism and stamping equipment: place the steel plate in the forming groove 50 at the top of the forming seat 30 to stamp the steel plate. When removing the formed steel plate, rotate the drive rod 210. The drive rod 210 drives the threaded rod 410 to rotate, which in turn drives the lifting tube 420 and the lifting plate 430 to move upward, thereby causing the top plate 60 to move upward and push the formed steel plate out of the forming groove 50. Then, start the electric push rod 710, which drives the push plate 720 to move horizontally to push the steel plate to one side of the forming seat 30 for easy removal. After that, reset the top plate 60 and the push plate 720.

[0031] It should be noted that the specific model and specifications of the electric linear actuator 710 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
