Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to an automatic material pushing device for a numerically controlled hydraulic gate type plate shearing machine. Background Art

[0002] In the sheet metal processing and manufacturing industries such as automobile production and processing, shipbuilding, etc., CNC hydraulic gate shears are used frequently. By using the moving upper blade and the fixed lower blade and a reasonable blade gap, they apply shear force to metal sheets of various thicknesses, so that the sheets can be broken and separated according to the required size.

[0003] The patent specification with the announcement number CN219520648U discloses an automatic material pushing device for a CNC hydraulic gate shearing machine, comprising: a screw rod, which can rotate with its own axis as the central axis, and the screw rod is sleeved with a nut seat connected by a thread; a slide rod, which is sleeved with a sliding seat connected by a sliding connection, and the slide seat and the nut seat are fixedly connected by a connecting rod; and a hydraulic clamp, which is arranged below the connecting rod, the middle of the connecting rod is fixedly connected with a fixed rod, the bottom of the fixed rod is fixedly connected to the hydraulic clamp, and the bottom of the hydraulic clamp is fixedly connected with a slider, and the slider can slide linearly along the sliding direction of the slider. The problem in the prior art that workers manually push the plate into the shearing machine, and the manual pushing has a great safety hazard due to the danger of the shearing machine's knives, is solved.

[0004] However, in the implementation of relevant technologies, it was found that the automatic pushing device of a CNC hydraulic gate shearing machine designed as above has the following problems: in the prior art, the hydraulic clamp drives the plate to perform the pushing operation by driving components such as a screw rod, a nut seat and a screw rod, but this form can only place one plate. After pushing the material once during the pushing process, the plate has to be manually moved and placed again before the next pushing. The labor intensity is too high and the efficiency is relatively slow. In view of this, an automatic pushing device of a CNC hydraulic gate shearing machine is provided to overcome the above defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an automatic material pushing device for a numerically controlled hydraulic gate type shearing machine.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic material pushing device for a CNC hydraulic gate shearing machine, comprising a shearing machine body, a material inlet is provided at the front end of the shearing machine body, and connecting blocks are installed on both sides of the outer wall of the shearing machine body by bolts, and a material pushing mechanism is provided on one side of the connecting block;

[0007] The pushing mechanism comprises a structural frame, the two structural frames are respectively fixed on the outer walls of the corresponding connecting blocks, the two structural frames are fixed with connecting plates at one end away from the connecting blocks, and the bottom end of the structural frame is embedded with universal wheels, and the bottom ends of the relative outer walls of the two structural frames are fixed with load-bearing rods, the outer wall of the connecting block is embedded with a pushing motor, and the connecting block is provided with a storage groove facing the outer wall of the structural frame, the power output end of the pushing motor is connected with a first threaded rod, and the outer side of the first threaded rod is slidably connected with a pushing plate, and the structural frame, connecting plate, universal wheels and load-bearing rods are used to form a trolley, which is convenient for stacking multiple groups of plates for flexible movement and pushing different shearing machines, and the load-bearing rods are convenient for placing batches of plates through forklift pallets via forklifts, thereby avoiding excessive labor intensity of manual handling.

[0008] As a further description of the above technical solution: the push plate is threadedly connected to the first threaded rod, and the push plate forms a sliding structure between the first threaded rod and the structural frame. The first threaded rod is driven by the push motor, so that the push plate slides and pushes the top layer of the plate to the feeding port of the shearing machine body for loading, avoiding manual pushing and reducing labor intensity.

[0009] As a further description of the above technical solution: a clamping motor is embedded in the bottom end of the other side of the outer wall of the structural frame, and the power output end of the clamping motor is connected to a second threaded rod, and the outer wall of the second threaded rod is slidably connected to a clamping plate. Under the operation of the clamping motor, the clamping plate is driven by the second threaded rod to slide toward the structural frame, thereby clamping and correcting the plate to avoid deviation during loading.

[0010] As a further description of the above technical solution: the second threaded rod is threadedly connected to the clamping plate, and a sliding structure is formed between the clamping plate and the load-bearing rod. The clamping plate axially penetrates into the load-bearing rod to facilitate stable sliding along the load-bearing rod.

[0011] As a further description of the above technical solution: a jacking mechanism is arranged on one side of the load-bearing rod, and the jacking mechanism includes a mounting shell, and the mounting shell is fixed between two load-bearing rods on the outer walls relative to two structural frames, and a plurality of groups of hydraulic rods are embedded inside the mounting shell, and a jacking plate is connected to the power output end of the hydraulic rod. When a group of plates is pushed, the jacking plate is pushed up by the hydraulic rod, thereby pushing the plates to be flush with the pushing plate, and then the next step of pushing and loading is carried out.

[0012] As a further description of the above technical solution: the jacking plate forms a telescopic structure with the mounting shell through the hydraulic rod, and a sliding structure is formed between the jacking plate and the structural frame. The length of the jacking plate is shorter than the span of the two sets of structural frames, and space is reserved for placing plates of different lengths to avoid mutual influence and limit causing the jacking plate to be unable to rise.

[0013] As a further description of the above technical solution: a pressure sensor is axially embedded in the top of the structural frame, and a roller is rotatably connected to the outer wall of the shearing machine body near the structural frame. When the plate rises, it touches the pressure sensor, which is convenient for transmitting the signal to the control end of the shearing machine body, and starting the pushing motor to push the material. When there is no induction, the pushing motor rotates in the opposite direction to reset, allowing the pushing plate to reset, and then the hydraulic rod is started again to lift the plate again, thereby improving the smoothness of pushing the plate through the roller.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs an automatic pushing device for a numerically controlled hydraulic gate-type shearing machine. A trolley composed of a structural frame, a connecting plate and universal wheels is convenient for flexible movement and is connected to different shearing machine bodies through bolts through connecting blocks, thereby improving flexibility and applicability. A forklift is allowed to load batches of plates through a forklift pallet through a load-bearing rod, thereby avoiding the need for manual placement of plates for multiple times after pushing the materials in the later stage, which results in excessive labor intensity. The first threaded rod is driven to work by a pushing motor, thereby facilitating the pushing of the plates into the feeding port of the shearing machine body through the pushing plate, thereby avoiding manual pushing.

[0016] The utility model designs an automatic pushing device for a numerically controlled hydraulic gate-type shearing machine. The shearing machine body is provided with a PLC control end. When the hydraulic rod pushes the lifting plate to drive the plate to rise, it touches the pressure sensor. The PLC control end receives the signal to start the pushing motor, allowing the pushing plate to push the plate into the feed port. When the pressure sensor is insensitive after the plate enters, the pushing motor drives the pushing plate to reset, and then starts the hydraulic rod to continue to lift the plate, thereby forming an automatic form, avoiding manual handling and operation, reducing labor intensity and improving efficiency.

[0024] The pushing mechanism 4 includes a structural frame 401, and the two structural frames 401 are respectively fixed on the outer walls of the corresponding connecting blocks 3. A connecting plate 402 is fixed at one end of the two structural frames 401 away from the connecting block 3. A universal wheel 403 is embedded at the bottom end of the structural frame 401, and a load-bearing rod 404 is fixed at the bottom end of the relative outer walls of the two structural frames 401. A pushing motor 405 is embedded in the outer wall of the connecting block 3, and a storage groove 408 is provided on the outer wall of the connecting block 3 facing the structural frame 401. The power output end of the pushing motor 405 is connected to a first threaded rod 406, and a pushing plate 407 is slidably connected to the outside of the first threaded rod 406. The structural frame 401, the connecting plate 402, the universal wheel 403 and the load-bearing rod 404 form a trolley, which is convenient for stacking multiple groups of plates for flexible movement and pushing materials for different shearing machines. The load-bearing rod 404 is convenient for placing batches of plates through a forklift pallet via a forklift to avoid excessive labor intensity in manual handling.

[0025] As a further implementation scheme of the above technical scheme: the push plate 407 is threadedly connected to the first threaded rod 406, and the push plate 407 forms a sliding structure between the first threaded rod 406 and the structural frame 401. The first threaded rod 406 is driven by the push motor 405, so that the push plate 407 slides to push the top layer of the plate, and moves to the feed port 2 of the shearing machine body 1 for loading, avoiding manual pushing and reducing labor intensity.

[0026] As a further implementation scheme of the above technical scheme: a clamping motor 5 is embedded at the bottom end of the other side of the outer wall of the structural frame 401, and the power output end of the clamping motor 5 is connected to a second threaded rod 6, and the outer wall of the second threaded rod 6 is slidably connected to a clamping plate 7. Under the operation of the clamping motor 5, the clamping plate 7 is driven by the second threaded rod 6 to slide toward the structural frame 401, so as to clamp and correct the plate to avoid deviation during loading.

[0027] As a further implementation scheme of the above technical scheme: the second threaded rod 6 is threadedly connected to the clamping plate 7, a sliding structure is formed between the clamping plate 7 and the load-bearing rod 404, and the clamping plate 7 axially penetrates into the load-bearing rod 404 to facilitate stable sliding along the load-bearing rod 404.

[0028] During specific implementation, the structural frame 401, the connecting plate 402 and the universal wheel 403 form a trolley, and the stacked plates are supported by the load-bearing rod 404 for flexible movement. Then, the trolley is fixed to the shearing machine body 1 through the connecting block 3 and bolts to prevent sliding and detachment during loading. The plates are aligned by clamping the connecting block 3 and the shearing machine body 1. At the same time, the clamping motor 5 drives the second threaded rod 6 to allow the clamping plate 7 to slide toward a set of structural frames 401, so that the plates are clamped and limited on all sides to avoid displacement during loading. The pushing motor 405 drives the first threaded rod 406, so that the pushing plate 407 drives the plates to move toward the shearing machine body 1 for loading. The connecting plate 402 is provided with a storage groove 408 for accommodating the pusher plate 407 to avoid affecting the limiting and alignment of the plates.

[0029] As a further implementation scheme of the above technical scheme: a jacking mechanism 8 is arranged on one side of the load-bearing rod 404, and the jacking mechanism 8 includes a mounting shell 802, and the mounting shell 802 is fixed between two load-bearing rods 404 on the outer walls opposite to each other of the two structural frames 401, and multiple groups of hydraulic rods 803 are embedded in the interior of the mounting shell 802, and the power output end of the hydraulic rod 803 is connected to the jacking plate 801. When a group of plates is pushed, the hydraulic rod 803 pushes the jacking plate 801 up, thereby pushing the plates to be flush with the pushing plate 407, and then proceeding to the next step of pushing and loading.

[0030] As a further implementation scheme of the above technical scheme: the lifting plate 801 forms a telescopic structure with the mounting shell 802 through the hydraulic rod 803, and a sliding structure is formed between the lifting plate 801 and the structural frame 401. The length of the lifting plate 801 is shorter than the span of the two sets of structural frames 401, and space is reserved for placing plates of different lengths to avoid mutual influence and limit causing the lifting plate 801 to be unable to rise.

[0031] As a further implementation scheme of the above technical scheme: a pressure sensor 9 is axially embedded in the top of the structural frame 401, and a roller 10 is rotatably connected to the outer wall of the shearing machine body 1 near the structural frame 401. When the plate rises, it touches the pressure sensor 9, which is convenient for transmitting the signal to the control end of the shearing machine body 1, and starting the pushing motor 405 to push the material. When there is no induction, the pushing motor 405 rotates in the opposite direction to reset, allowing the pushing plate 407 to reset, and then the hydraulic rod 803 is started again to lift the plate again, and the roller 10 is used to improve the smoothness of the plate pushing.

[0032] During specific implementation, when the pushing motor 405 works and the pushing plate 407 pushes the top plate to load the material, the pressure sensor 9 is in a non-sensing state, and the pushing motor 405 drives the pushing plate 407 to reset, and then the hydraulic rod 803 is started, and the hydraulic rod 803 passes through the mounting shell 802, allowing the lifting plate 801 to push the plate up until the top plate touches the pressure sensor 9. The shearing machine body 1 is provided with a PLC control end to facilitate sensing signals and controlling power components. After the pressure sensor 9 senses, the pushing motor 405 is started to push the material, thereby forming automation, avoiding manual participation, reducing labor intensity and improving efficiency.
