Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a sheet metal processing sawing and blanking device with a pushing mechanism. Background Technology

[0002] Existing feeding mechanisms are mostly rigid structures, with the pusher (claw) typically only having 1-2 contact points. When processing boards longer than 2.4 meters or of uneven thickness, the feeding point deviates from the board's center of gravity, easily causing a "push-off" phenomenon. Existing equipment lacks a multi-segment, independently adjustable claw design, failing to adaptively adjust the clamping posture according to the board's curvature, resulting in the cutting end face not being perpendicular to the reference plane. Traditional automatic saws employ a "full-stroke retraction" mode. For example, when sawing a 500mm long board, the feeding mechanism still needs to move from the end of the worktable (origin) to 500mm, cut, and then retract to the end, waiting for unloading before restarting. This operational logic results in a significant amount of processing time being spent on the idle stroke, leading to an excessively long cycle time, which cannot meet the demands of high-speed assembly line operations.

[0003] CN107839021A discloses an adjustable wood cutting and processing device. Supports are provided at the four corners of the lower end of the worktable. A lifting mechanism is connected to a pallet that can move on the lifting mechanism. A motor is installed on the pallet, and a saw blade is connected to the motor. The limiting mechanism includes a cylinder installed on the worktable, and a baffle is connected to the piston rod of the cylinder. This invention has the advantages of simple structure, convenient operation, and easy adjustment. Summary of the Invention

[0004] To address the issue that traditional sawing processes in existing technologies typically rely on manual feeding, positioning, and pushing of sheet metal, while table saws are simple in structure and low in cost, their operational safety is poor. Manual pushing can easily lead to workplace injuries (such as finger cuts) due to fatigue or operational errors. Furthermore, processing accuracy is greatly affected by human factors, making it difficult to guarantee batch stability. The technical solution provided by this invention is as follows: A sheet metal processing sawing device with a pushing mechanism, comprising a base frame, the base frame being configured with a hollow shape, a support fixedly connected to the bottom of the base frame, a sliding rod fixedly connected to the top of the base frame via the support, and an electric screw fixedly connected to the side of the top of the base frame away from the sliding rod via the support. The guide roller has threads on its side and is located in a hollowed-out position at the top of the equipment base. The side of the guide roller is rotatably connected to the side of the equipment base. A push plate assembly is sleeved and threadedly connected to the side of the electric screw. A lower pressure roller is fixedly connected to the bottom of the equipment base away from the push plate assembly. A cutting device is fixedly connected to the top of the equipment base at a position on one side of the lower pressure roller. The push plate assembly includes a push plate, a threaded sleeve fixedly connected to the side of the push plate, a sliding sleeve fixedly connected to the side of the push plate away from the threaded sleeve, a guide strip fixedly connected to the bottom of the push plate, and a conveying groove fixedly connected to the bottom of the push plate.

[0005] The top of the push plate is provided with a sliding groove, and a fixing component is slidably connected to the inner wall of the sliding groove. The threaded sleeve is fitted on the side of the electric screw and threadedly connected to the side of the electric screw. The sliding sleeve is fitted on the side of the sliding rod and slidably connected to the side of the sliding rod. The top of the equipment base is provided with a sliding groove that matches the guide bar. The conveying groove is located above the guide roller. The equipment base and the equipment bracket provide overall support for the plate.

[0006] The guide rollers convey the sheet material and increase the friction on the sheet material through the threaded grooves on the side of the guide rollers, thus facilitating the conveying of the sheet material. The sliding rod guides the push plate assembly, and the electric screw is used to rotate and push the push plate assembly to move. When the sheet material is placed on top of the guide rollers, the push plate assembly fixes the sheet material and, together with the electric screw, pushes the push plate assembly to move the sheet material. The lower pressure roller presses down on the top of the sheet material.

[0007] This prevents vibration from affecting cutting accuracy during plate cutting, and cuts the plate by pressing down on the cutting device. The threaded sleeve facilitates the movement of the push plate as a whole through the thread, the guide strip facilitates the guidance of the push plate, the sliding sleeve stabilizes the movement of the push plate, and the conveying groove facilitates the passage of the guide roller.

[0008] This allows the sheet material to move smoothly. The sliding groove facilitates the movement of the fixing components, which can be moved to different positions to fix the top of the sheet material. This keeps the sheet material in a fixed state during processing and cutting, and works in conjunction with the lower pressure roller to stabilize the sheet material, thereby improving cutting accuracy.

[0009] Preferably, the fixing assembly includes a fixing plate, a sliding sleeve fixedly connected to the top of the fixing plate, a sliding column slidably connected to the top of the sliding sleeve, a pulling rod fixedly connected to the top of the sliding column, a return spring sleeved and fixedly connected to the side of the sliding column, a fixing fork fixedly connected to the bottom of the sliding column, a return spring rod fixedly connected to the side of the fixing plate, a height adjusting rod rotatably connected to the side of the return spring rod, and the bottom of the height adjusting rod extending into the interior of the sliding groove and slidably connected to the inner wall side of the sliding groove.

[0010] Preferably, the fixing plate includes a connecting base plate, a reinforcing strip is fixedly connected to the top of the connecting base plate, a reset sleeve is fixedly connected to the side of the reinforcing strip, the reset sleeve is sleeved on the side of the reset spring rod and rotatably connected to the side of the reset spring rod, the top of the connecting base plate is fixedly connected to the bottom of the sliding sleeve, and the bottom of the reset spring is in contact with the top of the connecting base plate.

[0011] Preferably, the fixed fork includes a movable seat, a rotating column is rotatably connected to the side of the movable seat, a limiting column is fixedly connected to the side of the movable seat at a position on one side of the rotating column, a limiting fork is fixedly connected to the side of the rotating column, the top of the movable seat is fixedly connected to the bottom of the sliding column, the side of the limiting fork contacts the side of the limiting column, and after the plate is placed, the pull bar is manually moved.

[0012] The pulling rod moves, causing the sliding column to move. The movement of the sliding column causes the return spring to deform. The elastic force of the return spring causes the sliding column to press down. The pressing down of the sliding column causes the fixed fork to descend. During the movement of the sliding column, the elastic force provided by the return spring rod causes the fixed plate to rotate along the side of the return spring rod.

[0013] The reset sleeve rotates along the side of the reset spring rod due to the elastic force of the reset spring rod. The reset sleeve drives the reinforcing strip to rotate, the reinforcing strip drives the connecting base plate to rotate, the connecting base plate drives the sliding sleeve to rotate, and the sliding sleeve drives the sliding column.

[0014] During the process of the fixed fork being driven by the sliding column, the moving seat moves, which in turn moves the rotating column. The rotating column moves, which in turn moves the limiting fork to fix the top of the plate. The bottom of the limiting fork contacts the top of the plate, and the limiting fork rotates along the side of the rotating column. The combined action of multiple sets of limiting forks contacts and fixes plates with different surface shapes, and limits the rotation angle under the restriction of the limiting column, thus facilitating the fixation of the top of the plate.

[0015] Preferably, the height adjusting rod includes an adjusting screw, the bottom of which is rotatably connected to a sliding base, and a movable base is sleeved and threadedly connected to the side of the adjusting screw. The side of the movable base is rotatably connected to the side of the reset spring rod, and the sliding base extends into the interior of the sliding groove and is slidably connected to the interior side of the sliding groove.

[0016] When conveying plates of different thicknesses, the adjusting screw is rotated. The rotation of the adjusting screw causes the moving base to move along the side of the adjusting screw, rising or falling. The movement of the moving base causes the return spring rod to rise and fall. The fall of the return spring rod causes the connecting base plate to fall.

[0017] The sliding base is designed to allow the adjusting screw to slide along the inner wall of the sliding groove, thus facilitating the sliding of the base along the inner wall of the sliding groove. This allows for the fixing of plates of different widths, and the adjusting screw can also be used to fix plates of different thicknesses, making it easier to push the plates during cutting.

[0018] Preferably, the lower pressure roller includes a spring rod, a limiting roller is rotatably connected to the movable end of the spring rod, a guide sleeve is sleeved and fixedly connected to the side of the limiting roller, the fixed end of the spring rod is fixedly connected to the top of the equipment base frame, and the guide sleeve is located on one side of the guide roller.

[0019] Preferably, the cutting device includes a connecting base, a protective shell is fixedly connected to the bottom of the connecting base, an electric saw is rotatably connected to the inner wall of the protective shell, a belt drive assembly is rotatably connected to the side of the protective shell, a rotating ring is fixedly connected to the output end of the belt drive assembly, and a guide vane is fixedly connected to the inner side of the rotating ring.

[0020] The movable end of the telescopic rod is fixedly connected to the side of the connecting base, and a guide tube is fixedly connected to the side of the fixed end of the telescopic rod. The top of the guide tube is fixedly connected to the bottom of the equipment base frame. The rotating ring is connected to the side of the protective shell and rotates. During the process of pushing the plate, the top edge of the plate contacts the edge of the limiting roller. The side of the limiting roller is forced to move upward, and the movement of the limiting roller drives the movable end of the spring rod to move.

[0021] The movable end of the spring rod generates elastic force to drive the limiting roller to press down. The guide sleeve is set in the process of the limiting roller pressing down. The limiting roller presses down and drives the guide sleeve to descend. The guide sleeve contacts and fixes the top of the plate. The inclined setting of the guide sleeve increases the contact area with the plate, thereby increasing the stability of the plate during the pushing process. It works with the limit fork to fix both ends of the plate, thereby stabilizing the posture of the plate. After the plate moves to the appropriate position.

[0022] Start the chainsaw and telescopic rod. The movable end of the telescopic rod descends, causing the connecting base to move. The moving connecting base causes the protective shell to move. The protective shell causes the rotating chainsaw to move. The chainsaw cuts off the top of the board. During the rotation of the chainsaw, the belt drive assembly rotates. The rotation of the belt drive assembly causes the rotating ring to rotate. The rotation of the rotating ring causes the air guide vanes to move.

[0023] The moving air guide vanes guide air along the side of the protective shell into the interior of the shell and then spray it out along the bottom of the shell. This pneumatically guides the sawdust during the cutting of the board, making it easier to clean up the sawdust in time, observe the cutting position, and adjust accordingly to improve cutting accuracy. The guide tube is used to guide and collect the sawdust.

[0024] The beneficial effects of the technical solution provided by this invention include: 1. The equipment base and support frame provide overall support for the sheet metal. Guide rollers are used for conveying the sheet metal, and the threaded grooves on the side of the guide rollers increase the friction with the sheet metal, making the conveying of the sheet metal more stable. A sliding rod provides movement guidance for the pusher assembly, and an electric screw pushes the pusher assembly forward. After the sheet metal is placed on top of the guide rollers, it is fixed by the pusher assembly and moves together with the pusher assembly under the push of the electric screw. The pressure roller presses down on the top of the sheet metal to prevent vibration during cutting and ensure cutting accuracy. The cutting device presses down to complete the cutting of the sheet metal. A threaded sleeve drives the pusher plate to move as a whole, a guide bar guides the pusher plate, and a sliding sleeve maintains the smooth movement of the pusher plate. The conveying groove allows the guide rollers to pass smoothly, and the sheet metal moves smoothly. The sliding groove allows the fixing assembly to move to different positions, fixing the top of the sheet metal during processing and cutting, and together with the pressure roller, maintaining the stability of the sheet metal and improving cutting accuracy.

[0025] 2. After the sheet material is placed, manually move the pull bar. The sliding column moves accordingly, causing the return spring to deform. The spring force of the return spring presses down the sliding column, driving the fixed fork down. As the sliding column moves, the spring force of the return spring rod causes the fixed plate to rotate along its side. The return sleeve rotates accordingly, driving the reinforcing strip and connecting base plate to rotate, which in turn causes the sliding sleeve and sliding column to rotate. When the moving seat moves, it drives the rotating column to move, causing the limiting fork to descend to the top of the sheet material and contact it. The limiting fork rotates along the side of the rotating column. Multiple sets of limiting forks work together to adapt to sheet materials with different surface shapes, achieving top fixation, and the limiting column restricts its rotation angle.

[0026] 3. When conveying plates of different thicknesses, rotate the adjusting screw, and the moving base will rise and fall along the side of the adjusting screw, causing the return spring rod and the connecting base plate to rise and fall accordingly. The sliding base slides along the inner wall of the sliding groove, allowing the adjusting screw to adapt to the fixing requirements of plates of different widths, thereby achieving the fixing of plates of different thicknesses and facilitating the pushing of plates during cutting.

[0027] 4. During the sheet material feeding process, the top edge of the sheet material contacts the limiting roller. The limiting roller moves upward under pressure, causing the movable end of the spring rod to move. The elastic force of the spring rod causes the limiting roller to press down. As the limiting roller presses down, the guide sleeve descends accordingly, contacting and fixing itself to the top of the sheet material. The inclined design of the guide sleeve increases the contact area with the sheet material, making the feeding process more stable. Together with the limiting fork, it fixes both ends of the sheet material, maintaining its stable posture. After the sheet material moves to the appropriate position, the electric saw and telescopic rod are activated. The movable end of the telescopic rod descends, moving the connecting base and protective shell, allowing the rotating electric saw to cut the top of the sheet material. As the electric saw rotates, the belt drive assembly drives the rotating ring to rotate, causing the air guide vanes to move. This guides airflow along the side of the protective shell and ejects it from the bottom, creating airflow guidance during sheet material cutting. This helps to promptly remove debris, facilitates observation of the cutting position, and improves cutting accuracy. The guide tube collects and guides the sawdust. Attached Figure Description

[0030] Example 1, please refer to Figures 1-2 This invention provides a technical solution: a sheet metal processing sawing and blanking device with a pushing mechanism. The device base 1 and device support 2 provide overall support for the sheet metal. A guide roller 3 conveys the sheet metal, and the threaded grooves on the side of the guide roller 3 increase the friction on the sheet metal, thus facilitating its conveying. A sliding rod 4 guides a pusher assembly 6. An electric screw 5 is used to screw and push the pusher assembly 6 to move. When the sheet metal is placed on top of the guide roller 3, it is fixed by the pusher assembly 6, which in turn pushes the pusher assembly 6 with the electric screw 5. The pusher assembly 6 pushes the sheet metal to move. A lower pressure roller 7 presses down on the top of the sheet metal to prevent damage during cutting. Vibration affects cutting accuracy, and the cutting device 8 cuts the plate by pressing down. The threaded sleeve 602 facilitates the movement of the push plate 601 through the thread. The guide strip 604 guides the push plate 601. The sliding sleeve 603 stabilizes the movement of the push plate 601. The conveying groove 605 facilitates the passage of the guide roller 3, thus smoothly pushing the plate. The sliding groove 606 facilitates the movement of the fixing component 607. The fixing component 607 moves to different positions to fix the top of the plate, maintaining a fixed state during plate cutting and stabilizing the plate with the pressing roller 7, thereby improving cutting accuracy.

[0031] Example 2, please refer to Figures 1-5Based on the first embodiment, after the plate is placed, the pull rod 6074 is manually moved. The movement of the pull rod 6074 causes the sliding column 6073 to move. The movement of the sliding column 6073 causes the return spring 6075 to deform. The elastic force of the return spring 6075 causes the sliding column 6073 to press down. The pressing down of the sliding column 6073 causes the fixed fork 6076 to descend. During the movement of the sliding column 6073, the elastic force provided by the return spring rod 6077 causes the fixed plate 6071 to rotate along the side of the return spring rod 6077. The return sleeve 60713 is rotated along the side of the return spring rod 6077 by the elastic force of the return spring rod 6077. The return sleeve 60713 causes the reinforcing strip 60712 to rotate. The rotation drives the connecting base plate 60711 to rotate, which in turn drives the sliding sleeve 6072 to rotate. The sliding sleeve 6072 then drives the sliding column 6073. During the movement of the sliding column 6073, the moving seat 60761 moves, causing the rotating column 60762 to move. The rotating column 60762 then moves, causing the limiting fork 60764 to fix the top of the plate. The bottom of the limiting fork 60764 contacts the top of the plate, and the limiting fork 60764 rotates along the side of the rotating column 60762. The combined action of multiple limiting forks 60764 contacts and fixes plates with different surface shapes, and the rotation angle is limited by the limiting column 60763, thus facilitating the fixation of the top of the plate.

[0032] Example 3, please refer to Figures 1-6 Based on the second embodiment, when conveying plates of different thicknesses, the fixed height is changed by rotating the adjusting screw 60781 via the height adjusting rod 6078. The rotation of the adjusting screw 60781 causes the movable base 60783 to move along the side of the adjusting screw 60781, rising or falling. The movement of the movable base 60783 causes the return spring rod 6077 to rise and fall. The fall of the return spring rod 6077 causes the connecting base plate 60711 to fall. The sliding base 60782 facilitates the sliding of the adjusting screw 60781 along the inner wall of the sliding groove 606, thereby facilitating the sliding of the sliding base 60782 along the inner wall of the sliding groove 606. This allows for the fixing of plates of different widths, and the adjusting screw 60781 facilitates the fixing of plates of different thicknesses, thus facilitating the pushing of plates during cutting.

[0033] Example 4, please refer to Figures 1-8Based on the third embodiment, during the pushing process of the sheet metal, the top edge of the sheet metal contacts the edge of the limiting roller 702. The side of the limiting roller 702 is subjected to force and moves upward. The movement of the limiting roller 702 drives the movable end of the spring rod 701 to move. The movable end of the spring rod 701 generates elastic force to push the limiting roller 702 downward. The guide sleeve 703 is set up during the downward pressing of the limiting roller 702. The downward pressing of the limiting roller 702 drives the guide sleeve 703 to descend. The guide sleeve 703 contacts and fixes the top of the sheet metal. The inclined setting of the guide sleeve 703 increases the contact area with the sheet metal, thereby increasing the stability of the sheet metal during the pushing process. It also works with the limiting fork 60764 to fix both ends of the sheet metal, thereby stabilizing the posture of the sheet metal. After the sheet metal moves to the appropriate position, the electric saw 803 and the telescopic rod 807 are started. The movable end of 807 descends, causing the connecting base 801 to move. The movement of the connecting base 801 causes the protective shell 802 to move. The protective shell 802 drives the rotating electric saw 803 to move. The electric saw 803 cuts off the top of the board. During the rotation of the electric saw 803, it drives the belt drive assembly 804 to rotate. The rotation of the belt drive assembly 804 drives the rotating ring 805 to rotate. The rotation of the rotating ring 805 drives the air guide vane 806 to move. The movement of the air guide vane 806 drives air to be introduced into the interior of the protective shell 802 along the side and sprayed out along the bottom of the protective shell 802. This provides pneumatic guidance for the debris when the board is cut, making it easier to clean up the debris in time, observe the cutting position, and adjust in time to improve cutting accuracy. The guide tube 808 is set to guide and collect the sawdust.

[0034] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
