Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of blanking devices, and more specifically, to a blanking device for punching iron accessories. Background Art

[0002] Iron accessories refer to various auxiliary parts made of iron materials, which are widely used in different fields and are often used for connection, fixation, support, etc. Common iron accessories such as connecting pieces made of angle steel, channel steel, and iron plates. In many application scenarios, in order to connect iron accessories with other parts, it is necessary to punch the surface of the iron accessories, and then connect the iron accessories with other parts through connectors such as bolts and nuts.

[0003] When punching iron accessories, the iron accessories are usually placed on a mold, and then the punch of a punching machine cuts and punches the surface of the iron accessories. Since the die holes of some molds are through holes, after punching, the cut waste will fall into the die holes of the mold and be caught by the waste chute below the mold to achieve blanking.

[0004] However, when the punch punches the iron accessories, if some irregular waste is generated, the waste is likely to get stuck in the die hole and difficult to pass through the die hole smoothly after passing through the die hole of the mold, or some debris may adhere to the inner side wall of the die hole of the mold. If not cleaned in time, it will affect the subsequent punching work. When cleaning, it is necessary to manually hold a tool to poke out the waste in the die hole, which is quite laborious. Summary of the Invention

[0005] To overcome the above defects, embodiments of the present disclosure provide a blanking device for punching iron accessories, which solves the technical problem that in the prior art, waste may get stuck or adhere to the die holes of the mold during punching, and subsequent manual cleaning is required, which is quite laborious.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a blanking device for punching iron accessories, including a support table. A material leakage through groove is formed on the surface of the support table, and a mold is fixedly installed in the material leakage through groove. A circular die hole is formed in the central part of the mold. The blanking device further includes a material passing roller, a dredging component, a beating component, and a material receiving box. The material passing roller is arranged above the support table. The dredging component is arranged on the side of the support table through a moving component, and the material passing roller is arranged on the dredging component and is used to drive the material passing roller to dredge the die hole of the mold. The beating component is arranged on the dredging component and is used to beat the mold while the material passing roller dredges the mold. The material receiving box is arranged on the side of the support table through a placement plate.

[0007] Further, the moving component includes a mounting plate, a reciprocating lead screw, a motor, a limiting rod, and a moving frame. Two of the mounting plates are fixedly installed on both sides of the support table respectively. The reciprocating lead screw is rotatably installed between the two mounting plates on the same side. The motor is installed on the side of the mounting plate, and the output end of the motor is coaxially connected to the reciprocating lead screw. The limiting rod is fixedly installed between the other two mounting plates. One end of the moving frame is threadedly connected to the reciprocating lead screw, and the other end of the moving frame is slidably installed on the limiting rod. A circular through groove is provided at the top end of the moving frame.

[0008] Further, the dredging component includes a mounting frame and a first electric cylinder. The mounting frame is fixedly installed at the top end of the moving frame. The first electric cylinder is installed at the top end of the mounting frame, and the top end of the material feeding roller is fixedly connected to the output end of the first electric cylinder.

[0009] Further, the flapping component includes two second electric cylinders, fixing plates, a rotating shaft, flapping rods, and a transmission component. The two second electric cylinders are both installed at the top end of the moving frame. The two fixing plates are respectively fixedly installed on the output ends of the two second electric cylinders. The rotating shaft is rotatably installed through the two fixing plates. The two flapping rods are both fixedly installed on the rotating shaft. The transmission component is arranged on the rotating shaft.

[0010] Further, the transmission component includes a connecting block, a rack, and a toothed ring. The connecting block is fixedly installed on the side of the material feeding roller. The rack is fixedly installed on the side of the connecting block. The toothed ring is fixedly installed on the rotating shaft, and the toothed ring meshes with the rack.

[0011] Further, a positioning plate with a positioning groove at the top end is fixedly installed on the inner side wall of the mounting frame, and a positioning frame is fixedly installed on the side of the material feeding roller. The positioning frame is adapted to the positioning groove of the positioning plate.

[0012] Further, slots are provided on the sides of the fixing plate and the rotating shaft, and a plug-in frame is detachably installed in the slots.

[0013] Further, a stop block is fixedly installed on the side of the support table. When the side of the moving frame is in contact with the side of the stop block, the material feeding roller is located directly above the die hole of the mold.

[0014] Furthermore, when the slots of the rotating shaft and the fixing plate are at the same horizontal position, the side of the flapping rod is in contact with the side of the mold.

[0015] Further, a material passing bead is fixedly installed at the bottom end of the material passing roller, and when the material passing bead is located in the die hole of the mold, the outer side wall of the material passing bead is attached to the inner side wall of the die hole of the mold.

[0016] The beneficial effects of the embodiments of the present disclosure are as follows: 1. In the present disclosure, after punching the workpiece, if there is waste adhered or stuck in the die hole of the mold, the material passing roller can be moved above the mold through the moving component, and then the material passing roller can be moved into the die hole of the mold through the dredging component, so as to dredge the waste in the die hole. Moreover, when the material passing bead at the bottom end of the material passing roller enters the die hole, it can be attached to the inner side wall, so that the waste in the die hole can be better cleaned.

[0017] 2. In the present disclosure, when controlling the up and down movement of the material passing roller, the flapping rod can be synchronously driven by the flapping component to flap the side of the mold, so that the relatively loose waste adhered to the inner side wall of the die hole of the mold can be vibrated down by inertia. Through the cooperation of dredging and flapping, the effect of material removal is better.

[0018] In summary, through the mutual cooperation among the material passing roller, the dredging component, the flapping component and the material receiving box, the device can clean the waste remaining in the die hole of the mold after punching the iron attachment, which is more labor-saving compared with manual cleaning, and there is no need for the staff to clean it many times after punching several iron attachments.

Therefore, they should not be understood as limitations on the present disclosure.

[0027] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] like Figures 1 to 6 As shown, it shows a stripping device for punching iron accessories in one embodiment of the present disclosure, including a support table 1, a surface of the support table 1 is provided with a leakage groove, a mold 2 is fixedly installed in the leakage groove, and a circular mold hole is provided in the center of the mold 2. First, the punching machine is installed on the support table 1, and the iron accessory is placed on the upper surface of the mold 2 when punching. Then, the punching machine uses the mold 2 to punch the iron accessory. After punching is completed, the punch head is lifted up.

[0029] It also includes a material passing roller 3, a dredging component, a beating component and a material receiving box 4. The material passing roller 3 is arranged above the support platform 1. The dredging component is arranged on the side of the support platform 1 through a moving component, and the material passing roller 3 is arranged on the dredging component to drive the material passing roller 3 to pass material to the mold hole of the mold 2. The beating component is arranged on the dredging component to be used for the material passing roller 3 to dredge the mold 2 and beat the mold 2 at the same time. The material receiving box 4 is arranged on the side of the support platform 1 through a placement plate.

[0030] like Figure 6 As shown, after punching is completed, the waste material cut by the punch falls into the receiving box 4 through the die hole of the mold 2. If there is waste material stuck in the die hole of the mold 2, the material passing roller 3 is moved to the top of the die hole of the mold 2 by the moving component to clear it, as shown in FIG. Figure 2 As shown, the moving assembly includes a mounting plate 5, a reciprocating screw 6, a motor 7, a limit rod 8 and a moving frame 9. Two mounting plates 5 are fixedly installed on both sides of the support platform 1. The reciprocating screw 6 is rotatably installed between the two mounting plates 5 on the same side. The motor 7 is installed on the side of the mounting plate 5, and the output end of the motor 7 is coaxially connected to the reciprocating screw 6. The limit rod 8 is fixedly installed between the other two mounting plates 5. One end of the moving frame 9 is threadedly connected to the reciprocating screw 6, and the other end of the moving frame 9 is slidably installed on the limit rod 8, and a circular through groove is provided at the top of the moving frame 9.

[0031] Specifically, start the motor 7. The output end of the motor 7 drives the reciprocating lead screw 6 to rotate between the mounting plates 5. It should be added that one end of the reciprocating lead screw 6 and the moving frame 9 is in rolling thread transmission. Then, the moving frame 9 can move back and forth on the reciprocating lead screw 6 and the limiting rod 8, thereby driving the material feeding roller 3 to move above the die hole of the die 2. Since a stop block 22 is fixedly installed on the side of the support table 1, and when the side of the moving frame 9 is in contact with the side of the stop block 22, the material feeding roller 3 is directly above the die hole of the die 2. Then, when the moving frame 9 fits against the side of the stop block 22, it stops moving. At this time, the material feeding roller 3 is directly above the die hole of the die 2.

[0032] After the movement is completed, drive the material feeding roller 3 to move downward through the dredging component, so as to dredge the waste material stuck in the die hole of the die 2. As Figure 4 shown, the dredging component includes a mounting frame 10 and a first electric cylinder 11. The mounting frame 10 is fixedly installed at the top of the moving frame 9. The first electric cylinder 11 is installed at the top of the mounting frame 10, and the top end of the material feeding roller 3 is fixedly connected to the output end of the first electric cylinder 11. Specifically, by starting the first electric cylinder 11, the output end of the first electric cylinder 11 drives the material feeding roller 3 to move downward. It should be added that a through groove is opened at the top of the moving frame 9, and the material feeding roller 3 passes through the through groove of the moving frame 9 and the die hole of the die 2, so as to extrude the waste material stuck in the die hole. And a material feeding bead 23 is fixedly installed at the bottom end of the material feeding roller 3. When the material feeding bead 23 is located in the die hole of the die 2, the outer side wall of the material feeding bead 23 is in contact with the inner side wall of the die hole of the die 2. When moving downward, the material feeding bead 23 of the material feeding roller 3 enters the die hole of the die 2, and can poke out the internal waste material, making it fall into the lower material receiving box 4.

[0033] When the material feeding roller 3 moves downward, it can drive the beating rod 15 to rotate through the beating component, so as to contact and beat the side of the die 2. If there is waste material adhering to the inner side of the die hole of the die 2, it can be made to fall by beating the die 2 under the action of inertia. As Figure 5 shown, the beating component includes two second electric cylinders 12, fixing plates 13, a rotating shaft 14, beating rods 15 and a transmission component. There are two second electric cylinders 12, and both of the two second electric cylinders 12 are installed at the top of the moving frame 9. There are two fixing plates 13, and the two fixing plates 13 are respectively fixedly installed on the output ends of the two second electric cylinders 12. The rotating shaft 14 is rotatably installed through the two fixing plates 13. There are two beating rods 15, and both of the two beating rods 15 are fixedly installed on the rotating shaft 14. The transmission component is arranged on the rotating shaft 14. The transmission component includes a connecting block 16, a rack 17 and a gear ring 18. The connecting block 16 is fixedly installed on the side of the material feeding roller 3. The rack 17 is fixedly installed on the side of the connecting block 16. The gear ring 18 is fixedly installed on the rotating shaft 14, and the gear ring 18 meshes with the rack 17.

[0034] Specifically, when the material-passing roller 3 moves downward, the material-passing roller 3 drives the connecting block 16 and the rack 17 to move downward synchronously. The rack 17 then drives the toothed ring 18 meshing with it to rotate. The toothed ring 18 drives the rotating shaft 14 to rotate between the two fixed plates 13. The rotating shaft 14 drives the flapping rod 15 to rotate. When the material-passing roller 3 moves downward through the die hole, the flapping rod 15 rotates upward. When the material-passing roller 3 moves upward, the flapping rod 15 rotates downward to slap the side of the mold 2. Because when the rotating shaft 14 and the slot of the fixed plate 13 are at the same horizontal position, the side of the flapping rod 15 fits with the side of the mold 2, so as to achieve one-time dredging with one-time slapping, and the effect is better. If the waste in the die hole of the mold 2 is stuck inside the die hole of the mold 2 and only dredging is needed without slapping or the slapping has no effect, the second electric cylinder 12 can be started. The second electric cylinder 12 drives the two fixed plates 13 to move forward. The fixed plates 13 drive the rotating shaft 14 and the toothed ring 18 to move forward, so that the toothed ring 18 is disengaged from the meshing with the rack 17. Because slots are formed on the sides of the fixed plate 13 and the rotating shaft 14, and a plug-in frame 21 is detachably installed in the slots, the plug-in frame 21 is inserted into the slots of the fixed plate 13 and the rotating shaft 14 to prevent the rotating shaft 14 from rotating. When slapping is needed, because a positioning plate 19 with a positioning groove at the top is fixedly installed on the inner side wall of the mounting frame 10, and a positioning frame 20 is fixedly installed on the side of the material-passing roller 3, the positioning frame 20 is adapted to the positioning groove of the positioning plate 19, and the material-passing roller 3 is driven to move upward until the positioning frame 20 is inserted into the positioning groove of the positioning plate 19. It should be added that when the rotating shaft 14 and the slot of the fixed plate 13 are at the same horizontal position and the positioning frame 20 is inserted into the positioning groove of the positioning plate 19, the toothed ring 18 and the rack 17 are in a meshing state. The second electric cylinder 12 is started, and the second electric cylinder 12 drives the fixed plate 13 to move backward, so that the toothed ring 18 and the rack 17 are meshed again.

[0035] Working principle: When stripping the die hole of the die 2, first start the motor 7. The motor 7 drives the reciprocating lead screw 6 to rotate between the mounting plates 5, so that the moving frame 9 moves on the reciprocating lead screw 6 and the limit rod 8. When the side of the moving frame 9 fits against the stop block 22, at this time, the material passing roller 3 is located directly above the die hole of the die 2. Then start the first electric cylinder 11. The first electric cylinder 11 drives the material passing roller 3 to move downward, penetrate the moving frame 9 and enter the die hole of the die 2, push out the stuck waste material, and make it fall into the material receiving box 4. While the material passing roller 3 moves downward, it drives the connecting block 16 and the rack 17 to move downward. The rack 17 drives the toothed ring 18 to rotate, and the toothed ring 18 drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the beating rod 15 to rotate, so as to beat the die 2 while fitting against the side of the die 2. It can dredge while beating, and the effect is better. If there is no need to beat, the second electric cylinder 12 can be started. The second electric cylinder 12 drives the fixing plate 13 to move forward. The fixing plate 13 drives the rotating shaft 14 and the toothed ring 18 to move forward, so that the rack 17 will not drive the toothed ring 18 to rotate when the material passing roller 3 moves downward. The waste material that is beaten or extruded falls through the die hole into the material receiving box 4 below for collection.

Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
