Description

Technical Field

[0001] This utility model belongs to the field of punching and shearing technology, specifically relating to a sheet metal feeding mechanism for punching and shearing lines. Background Art

[0002] Sheet metal punching and shearing utilizes a moving upper blade and a fixed lower blade, and by setting a reasonable punching and shearing gap, applies shearing force to metal sheets of a certain thickness to obtain sheets of the required dimensions. During the punching and shearing process, the sheet metal to be punched and sheared needs to be transported and loaded.

[0003] Chinese patent document CN221064648U discloses a feeding mechanism for a sheet metal punching and shearing machine. It uses a fixed mechanism on the worktable to press down the sheet metal placed on the worktable. Then, through a connecting block whose movable range is limited by a second through slot, the length change of the extension end of the electric push rod is transmitted to the worktable, so that the worktable can stably move the sheet metal towards the shearing machine body. This eliminates the need for manual handling of the sheet metal, reduces the labor intensity of workers, and prevents the sheet metal from shifting.

[0004] However, in the existing technology, the movement of the sheet metal is limited by the moving distance of the worktable. When the length of the sheet metal exceeds the moving distance of the worktable, the feeding mechanism has difficulty feeding continuously. Therefore, a sheet metal feeding mechanism for punching and shearing lines is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a sheet metal feeding mechanism for punching and shearing lines.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A sheet metal feeding mechanism for a punching and shearing line includes a loading component that can support the sheet metal and facilitate its lateral movement within the mechanism. The loading component is provided with a limiting component that can limit the movable range of the sheet metal during lateral movement so that it can move centrally within the mechanism. A feeding component is provided on one side of the loading component that can appropriately clamp the sheet metal and drive it to move according to the punching and shearing requirements.

[0008] The feeding assembly includes a clamping component that can longitudinally clamp the sheet to limit its bounce and can move the sheet arbitrarily a certain distance.

[0009] The clamping component includes a frame, on which a bearing seat is fixedly mounted, and a rotating shaft is movably connected to the bearing seat. A V-shaped limit wheel is fixedly connected to the lower end of the rotating shaft.

[0010] The feeding assembly also includes a longitudinal movement component that allows the clamping component to flexibly adapt to the size of the sheet metal, and a drive component that allows the sheet metal to be moved as needed via the clamping component.

[0011] Preferably, the longitudinal moving component includes supports that are fixedly installed at the front and rear of the material carrying assembly, support rods are fixedly connected between the supports, and a double-acting screw is movably connected between the supports. A carrier frame is provided between the support rods and the double-acting screw.

[0012] Preferably, the clamping component further includes a limiting rod fixedly connected to the carrier, a spring movably connected to the outer side of the limiting rod, and a frame provided on one side of the spring.

[0013] Preferably, the driving component includes a first pulley fixedly connected to the upper end of the rotating shaft, a motor fixedly mounted on the frame, a second pulley fixedly connected to the output end of the motor, and a belt provided between the first pulley and the second pulley.

[0014] Preferably, the support is rotatably connected to the double-acting screw, the support rod is slidably connected to the carrier, and the double-acting screw is threadedly connected to the carrier.

[0015] Preferably, the carrier and the limiting rod are slidably connected to the machine frame.

[0016] Preferably, the bearing seat is rotatably connected to the rotating shaft.

[0017] The beneficial effects of this utility model are as follows: after the limiting component places the sheet material in the center position within the loading component, the longitudinal moving component drives the V-shaped limiting wheel in the clamping component to contact and clamp the sheet material. The driving component enables the V-shaped limiting wheel to rotate to the required angle, so that the V-shaped limiting wheel can both limit the sheet material and drive the sheet material to move any distance through its own rotation to meet processing needs.

[0027] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0028] like Figures 1-4 As shown, a sheet metal feeding mechanism for a punching and shearing line includes a loading component 1 that can support the sheet metal and allow it to move laterally within the mechanism. The loading component 1 is provided with a limiting component 2 that can limit the movable range of the sheet metal during lateral movement so that it moves centrally within the mechanism. A feeding component 3 is provided on one side of the loading component 1 that can appropriately clamp the sheet metal and drive it to move according to the punching and shearing requirements.

[0029] In this embodiment: the material loading assembly 1 includes a loading frame 101, a roller seat 102 is fixedly installed inside the loading frame 101, and a rotating roller 103 is movably connected between roller seats 102 with the same lateral position; the roller seat 102 and the rotating roller 103 are rotatably connected; the loading frame 101 provides installation positions for the roller seat 102 and some components of the feeding assembly 3, and the rotating roller 103 is installed at a certain height inside the loading frame 101 through the roller seat 102, so that the rotating roller 103 can support the plate material, and the plate material can be moved laterally with minimal friction through its own rotation.

[0030] In this embodiment: the limiting component 2 includes a conical limiting wheel 201 movably connected to the outer side of the rotating roller 103, and a locking knob 202 is fixedly installed on the conical limiting wheel 201; the conical limiting wheel 201 with a conical surface limits the longitudinal movable range of the sheet material when it moves laterally on the rotating roller 103; by tightening or loosening the locking knob 202, the locking knob 202 can rotate stably with the rotating roller 103, or the conical limiting wheel 201 can move longitudinally relative to the rotating roller 103 under the action of external force.

[0031] In this embodiment: the feeding assembly 3 includes a clamping member that can longitudinally clamp the sheet metal to limit its movement and drive it to move arbitrarily a certain distance. The clamping member includes a frame 307, on which a bearing 308 is fixedly mounted. A rotating shaft 309 is movably connected to the bearing 308. A V-shaped limiting wheel 310 is fixedly connected to the lower end of the rotating shaft 309. The feeding assembly 3 also includes a longitudinal moving member that allows the clamping member to flexibly adapt to the size of the sheet metal, and a driving member that allows the sheet metal to move as needed through the clamping member. The longitudinal moving member includes supports 301 fixedly mounted at the front and rear of the loading assembly 1, respectively, and a support rod fixedly connected between the supports 301. A bidirectional lead screw 303 is movably connected between the support 302 and the support 301. A carrier 304 is provided between the support 302 and the bidirectional lead screw 303. The clamping component also includes a limiting rod 305 fixedly connected to the carrier 304. A spring 306 is movably connected to the outer side of the limiting rod 305. A frame 307 is provided on one side of the spring 306. The driving component includes a first pulley 311 fixedly connected to the upper end of the rotating shaft 309. A motor 312 is fixedly installed on the frame 307. A second pulley 313 is fixedly connected to the output end of the motor 312. A belt 314 is provided between the first pulley 311 and the second pulley 313.

[0032] Support 301 is rotatably connected to double-acting screw 303, support rod 302 is slidably connected to carrier 304, double-acting screw 303 is threadedly connected to carrier 304, carrier 304 and limit rod 305 are slidably connected to machine frame 307, and bearing 308 is rotatably connected to rotating shaft 309.

[0033] Support rods 302 and bidirectional lead screws 303, which limit the movable range of the carrier frame 304, are installed on one side of the loading rack 101 via support 301. The longitudinal position of the carrier frame 304 within the mechanism is adjusted by rotating the bidirectional lead screw 303 relative to the support 301. The bidirectional lead screw 303 can be connected to an external handle with locking function or a power source, allowing the operator to control its rotation angle as needed. The carrier frame 304 drives the components mounted on it to move together. Limiting rods 305 and springs 306 further limit the movable range of the machine frame 307 on the carrier frame 304. Spring 306 also enables two frames 307 that are not subjected to external force to tend to move towards each other. The frame 307 provides a mounting position for the bearing seat 308 and the motor 312. The bearing seat 308 mounts the rotating shaft 309 on the side of the frame 307 close to the other frame 307. The rotation of the output end of the motor 312 is transmitted to the V-shaped limit wheel 310 through the second pulley 313, belt 314, first pulley 311, and rotating shaft 309. The V-shaped limit wheel 310, which can engage the edge of the sheet metal, can drive the sheet metal in contact to move laterally through its own rotation after the motor 312 is working.

[0034] Working principle: When this mechanism is installed for feeding sheet metal on the punching and shearing line, it is arranged with the feeding component 3 close to the punching and shearing line. After the arrangement is completed, the longitudinal position of each conical limit wheel 201 is pre-adjusted and locked according to the width of the sheet metal to be processed. The distance between the conical limit wheels 201 with the same lateral position is adjusted so that the closer they are to the feeding component 3, the closer they are to the width of the sheet metal. This allows the sheet metal to move slightly longitudinally to the center position of this mechanism and remain there when it moves laterally to the feeding component 3 on the roller 103, so that the feeding component 3 can fully contact the sheet metal.

[0035] When the sheet metal moves to the feeding assembly 3, the operator can control the bidirectional lead screw 303 to rotate a certain angle via a handle with locking function or a power source connected to it, so as to adjust the longitudinal position of the carrier 304 and allow the V-shaped limit wheel 310 to smoothly contact the edge of the sheet metal. When the spring 306 is properly compressed, the rotation of the bidirectional lead screw 303 is stopped. At this time, the V-shaped limit wheel 310 can clamp the sheet metal to a certain extent while engaging the edge of the sheet metal. Then, the motor 312 can be driven to rotate the V-shaped limit wheel 310 to the required angle. After rotation, the V-shaped limit wheel 310 can drive the sheet metal to move laterally stably, so that the sheet metal can move the required distance into the punching and shearing line according to the processing needs.

[0036] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
