Description

Technical Field

[0001] The present invention relates to the technical field of steel plate bending, and particularly relates to a steel plate bending device. Background Art

[0002] Before using a steel plate, it is necessary to bend the steel plate through a bending device so that the steel plate can be processed into a steel material with a fold angle. However, the pressing blocks of existing bending devices are generally welded to the device. When the pressing blocks press on the steel plate for a long time and reach the service life and need to be replaced, it is inconvenient to disassemble the pressing blocks, so it is inconvenient to replace the pressing blocks, resulting in poor usability.

[0003] To solve the above problems, a Chinese patent with the publication number CN221209511U discloses a steel plate bending machine, which includes a support base, a slot, a mounting plate, a bending mechanism, a bending component, and a limiting mechanism. The slot is opened on the support base, the mounting plate is arranged on the top of the support base, the bending mechanism is arranged on the mounting plate, the bending component is connected to the bending mechanism through the limiting mechanism. The bending mechanism includes a hydraulic component and a connecting plate. One end of the hydraulic component is connected to the mounting plate, and the other end of the hydraulic component is connected to the connecting plate. The bending component includes a long plate and a pressing block, and the pressing block is arranged on the long plate. When the pressing block is used for a long time and reaches the service life and needs to be replaced, controlling the limiting mechanism can separate the long plate from the connecting plate, and then the pressing block can be separated from the device, so as to facilitate replacing the new pressing block, that is, improving the practicability of the device.

[0004] The above device has the following problems in the actual use process: when the device is in use, workers need to hold the steel plate by hand to manually fix the steel plate. However, in the way of manual fixing by workers, workers need to be highly concentrated to ensure that the steel plate can be firmly fixed during the bending process. Once the attention of the workers deviates, the steel plate will shake or even fall, resulting in the bending operation of the steel plate cannot be carried out normally, that is, manually fixing the steel plate cannot guarantee the bending quality of the steel plate. Summary of the Invention

[0005] The present invention provides a steel plate bending device to solve the problem that the fixing quality of the existing bending device for the steel plate is poor during the bending of the steel plate.

[0006] To achieve the above object, the present invention adopts the following technical solution: A steel plate bending device, comprising a bending block, a resisting block, a groove formed in the bending block, a positioning mechanism arranged in the groove, and a bending mechanism arranged on the resisting block for bending the steel plate; the resisting block is fixedly connected to the bending block, and there is a gap between the resisting block and the bending block; the positioning mechanism includes a fixed block and positioning components symmetrically arranged on both sides of the groove along the length direction of the bending block; the fixed block is fixedly connected to the groove; the positioning components include side blocks, first wedge blocks, first springs, fixed blocks, pushing blocks, second wedge blocks, second springs, inserting blocks, side grooves formed in the fixed block, sliding grooves formed in the first wedge blocks, and insertion holes formed in the pushing blocks; the side blocks are vertically slidably connected to the side grooves; the first wedge blocks are fixedly connected to the side blocks; both ends of the first springs are respectively connected to the side blocks and the side grooves; the fixed blocks are slidably connected to the sliding grooves; the pushing blocks are slidably connected to the bending block, and the pushing blocks can reciprocate along the length direction of the groove; the second wedge blocks are fixedly connected to the pushing blocks, and the first wedge blocks are located on the movement tracks of the second wedge blocks; both ends of the second springs are respectively connected to the fixed blocks and the sliding grooves; the inserting blocks are vertically slidably connected to the outer wall of the bending block, the inserting blocks are located on the movement tracks of the insertion holes, and the inserting blocks can slide into and out of the insertion holes.

[0007] The principle and advantages of this solution are as follows:

[0008] 1. Place the steel plate to be bent in the gap between the resisting block and the bending block. After the steel plate is placed, the worker then pushes the two pushing blocks, causing the distance between the two pushing blocks to gradually decrease. During the movement of the pushing blocks, the second wedge blocks move synchronously. During the movement of the second wedge blocks, the first wedge blocks can move vertically upward under the action of the second wedge blocks. During the movement of the first wedge blocks, the fixed blocks move synchronously. During the movement of the fixed blocks, the fixed blocks push the steel plate towards the position where the resisting block is located. Then, under the combined action of the resisting block and the fixed blocks, the steel plate can be fixed between the resisting block and the fixed blocks, thus facilitating the subsequent bending operation of the steel plate to be carried out efficiently.

[0009] 2. When the fixed blocks perform the operation of pressing against the steel plate, the fixed blocks are slidably arranged in the sliding grooves to be applicable to steel plates of different thicknesses, enabling the fixed blocks to perform bending operations on steel plates of different thicknesses. Furthermore, the diversity of positioning for steel plates of different thicknesses is realized, thus ensuring the sufficiency of positioning the fixed blocks for steel plates of different thicknesses.

[0010] 3. The setting of the gap between the resisting block and the bending block is to facilitate the placement of steel plates of different thicknesses. Furthermore, the positioning of steel plates of different thicknesses by this device is realized, thus further ensuring the sufficiency of positioning steel plates of different thicknesses by this device. Therefore, through the relative sliding of the fixed blocks and the setting of the gap between the resisting block and the bending block, the positioning of steel plates of different thicknesses by this device is comprehensively ensured, that is, the practicability of positioning steel plates of different thicknesses is improved.

[0011] 4. When the jack moves to the position where the insertion block is located, stop pushing the push block, and then insert the insertion block into the jack. Therefore, under the action of the insertion block, it can be ensured that the push block will not change its position due to human interference or changes in external environmental factors, thereby ensuring that the fixed block can always stably position the steel plate during the bending of the steel plate, that is, improving the quality of positioning the steel plate.

[0012] 5. After the steel plate is fixed under the action of the two fixed blocks, then use the bending mechanism to bend the steel plate, so that the steel plate can be processed into a predetermined fold angle, thereby improving the efficiency of bending the steel plate and ensuring the quality of bending the steel plate.

[0013] In summary, by using machinery to replace manual labor to fix the steel plate, on the one hand, it enhances the effect of positioning the steel plate and improves the efficiency of positioning the steel plate. On the other hand, it saves unnecessary troubles for workers and saves unnecessary work processes, comprehensively improving the quality of positioning the steel plate.

[0014] Further, the positioning component further includes a linkage part; the linkage part includes a linkage block, a side block, a side plate, a third spring, a first guide block, a movable block, a linkage groove opened on the fixed block, a first side hole opened on the fixed block, a second side hole opened on the first wedge block, and a driving unit for driving the movable block to perform vertical reciprocating motion; the linkage block is slidably connected to the linkage groove; the side block is fixedly connected to the linkage block; the first side hole communicates with the linkage groove, the second side hole communicates with the chute, and the side block can perform vertical reciprocating motion in the first side hole and the second side hole; the side plate is fixedly connected to the side block; both ends of the third spring are respectively connected to the linkage block and the linkage groove; the first guide block is fixedly connected to the second wedge block; the movable block is slidably connected to the first guide block; the movable block abuts against the side plate.

[0015] During the relative sliding between the fixed block and the chute, the movable block moves vertically upward under the drive of the driving unit. During the movement of the movable block, the movable block drives the side block to move synchronously. Therefore, the side block can drive the linkage block to move vertically upward, and through the vertical upward acting force of the linkage block, the linkage block can exert a stronger acting force on the steel plate, thereby positioning the steel plate more firmly and fully, that is, further enhancing the positioning effect of the steel plate and ensuring that the steel plate can remain stable during bending.

[0016] Further, the positioning component further includes a positioning part; the positioning part includes a fixed plate, a first screw rod, a first guide rod, a first nut seat, an elastic block, and a power unit for driving the first screw rod to rotate; the fixed plate is fixedly connected to the second wedge block; the first screw rod is rotatably connected to the fixed plate; the first guide rod is fixedly connected to the fixed plate; the first nut seat is threadedly connected to the first screw rod, and the first nut seat is slidably connected to the first guide rod; the elastic block is fixedly connected to the first nut seat.

[0017] During the positioning of the steel plate under the combined action of the fixed block and the linkage block, the first screw rod will drive the first nut seat to move vertically upward along the length direction of the first guide rod. During the movement of the first nut seat, the elastic block moves synchronously. Therefore, while the elastic block moves horizontally along the width direction of the bending block, the elastic block can also move vertically upward. Furthermore, the elastic block can position different positions of the steel plate, that is, under the pressing action of the elastic block, the positioning effect of the steel plate can be further enhanced, and the positioning quality of the steel plate can be improved.

[0018] In summary, under the combined action of the linkage block and the elastic block, the steel plate can be firmly fixed at different positions of the steel plate, comprehensively improving the positioning effect and positioning quality of the steel plate.

[0019] Furthermore, the positioning component further includes a stopping part; the stopping part includes a second screw rod, a second guide rod, a second nut seat, a pressing plate, a rubber layer, and a stopping groove opened on the groove; the second screw rod is rotatably connected to the fixed plate, and the second screw rod is fixedly connected to the first screw rod; the second guide rod is fixedly connected to the fixed plate; the second nut seat is threadedly connected to the second screw rod, and the second nut seat is slidably connected to the second guide rod; the pressing plate is connected to the second nut seat; the rubber layer is fixedly connected to the pressing plate, the stopping groove is located on the movement track of the rubber layer, and the rubber layer can slide in and out of the stopping groove.

[0020] During the movement of the second screw rod with the second wedge block, the second nut seat can move vertically downward along the length direction of the second guide rod. During the movement of the second nut seat, the elastic layer can be gradually compressed, causing the elastic layer to deform. During the deformation of the elastic layer, until the elastic layer moves to the position where the stopping groove is located, the elastic layer slides into the stopping groove under the action of elastic force. At this time, the first wedge block also stops moving. During the stop movement of the second wedge block, by clamping the elastic layer in the stopping groove, the positioning of the second wedge block is realized, thereby ensuring that the second wedge block will not change its position, enabling the linkage block and the elastic block to efficiently position the steel plate, and further enhancing the positioning effect on the steel plate.

[0021] Furthermore, the stopping part further includes an auxiliary unit; the auxiliary unit includes a second guide block, a pressing block, an auxiliary groove opened on the nut seat, and a moving part for driving the pressing block to perform vertical reciprocating movement; the second guide block is fixedly connected to the fixed plate; the pressing block is slidably connected to the second guide block, and the pressing block is fixedly connected to the pressing plate; the pressing plate is vertically slidably connected to the auxiliary groove.

[0022] During the extrusion deformation of the rubber layer, the moving part drives the pressing block to move vertically downward. During the movement of the pressing block, the pressing block can further cause the elastic layer to deform, so that when the elastic layer slides into the stop groove, the elastic block can be efficiently filled into the stop groove. Moreover, when the elastic layer is located in the stop groove, the pressing block can ensure that the elastic layer will not slide out of the stop groove, thereby further enhancing the positioning effect of the elastic layer on the first wedge block and improving the positioning efficiency of the elastic layer.

[0023] Furthermore, the driving unit includes a driving shaft, a first gear, and a driving member for driving the driving shaft to rotate; the driving shaft is rotatably connected to the second wedge block; the first gear is fixedly connected to the driving shaft; the movable block is a first rack; the first gear meshes with the first rack.

[0024] By driving the driving shaft to rotate by the driving member, during the rotation of the driving shaft, the first gear moves synchronously. During the movement of the first gear, since the first gear meshes with the first rack, the first rack can reciprocate along the length direction of the first guide block.

[0025] Furthermore, the driving shaft is a worm; the power unit is a worm gear; the worm gear is fixedly connected to the first screw rod, and the worm gear meshes with the worm.

[0026] During the rotation of the worm, since the worm gear meshes with the worm, the worm can drive the first screw rod to rotate through the worm gear.

[0027] Furthermore, the moving part is a second gear; the second gear is fixedly connected to the worm; the pressing block is a second rack; the second gear meshes with the second rack.

[0028] During the rotation of the worm, the second gear rotates synchronously. During the rotation of the second gear, since the second gear meshes with the second rack, the second rack can reciprocate along the length direction of the second guide block.

[0029] Furthermore, the driving member includes a third guide block, a third rack, a rotating shaft, a third gear, a fourth spring, and a chamber opened in the second wedge block; the third guide block is fixedly connected to the chamber; one end of the third rack is slidably connected to the third guide block, and the other end of the third rack extends out of the chamber; the rotating shaft is rotatably connected to the chamber, and the rotating shaft is fixedly connected to the worm; the third gear is fixedly connected to the rotating shaft, and the third gear meshes with the third rack; both ends of the fourth spring are respectively connected to the third rack and the third guide block.

[0030] During the gradual reduction of the distance between the two second wedge blocks, the two third racks are abutted against each other, so that the third rack can slide in the chamber relative to the second wedge block. During the movement of the third rack, since the third rack meshes with the third gear, the third gear drives the rotating shaft to rotate. During the rotation of the rotating shaft, the worm rotates synchronously.

[0031] Further, it further includes limit members symmetrically arranged on both sides of the bending block along the length direction of the bending block; the limit members include limit blocks, pins, and limit holes opened on the limit blocks; the limit blocks are fixedly connected to the third rack, and the limit blocks are slidably connected to the second wedge block and the bending block respectively; the pins are slidably connected to the outer wall of the bending block, the pins are located on the movement track of the limit holes, and the pins can slide in and out of the limit holes.

[0032] During the movement of the third rack, the limit blocks move synchronously. During the movement of the limit blocks, when the limit holes move to the position where the pins are located, the limit blocks stop moving. After the limit blocks stop moving, the worker inserts the pins into the limit holes, so that the limit blocks will not change their positions under the influence of external environmental factors or human interference.

[0033] Through the above movement, after the limit blocks are positioned by the pins, the linkage blocks and the elastic blocks can firmly position the steel plate, and the rubber layer can stably position the second wedge block, thereby enhancing the stability of the linkage blocks, the elastic blocks, and the rubber layer, ensuring that the steel plate can be efficiently and comprehensively positioned during the positioning of the steel plate by the device, and enabling the bending mechanism to perform high-quality bending operations on the steel plate.

[0056] Specific implementation process:

[0057] Place the steel plate to be bent in the gap between the abutting block 2 and the bending block 1. After the steel plate is placed, the worker then pushes the two push hands 12, so that the distance between the two push blocks 8 gradually decreases. During the movement of the push block 8, the second wedge 9 moves synchronously. During the movement of the second wedge 9, the first wedge 6 can move vertically upward under the action of the second wedge 9. During the movement of the first wedge 6, the fixed block 7 moves synchronously. During the movement of the fixed block 7, the fixed block 7 pushes the steel plate towards the position where the abutting block 2 is located. Then, under the combined action of the abutting block 2 and the fixed block 7, the steel plate can be fixed between the abutting block 2 and the fixed block 7, so as to facilitate the subsequent bending operation of the steel plate to be carried out efficiently.

[0058] When the fixed block 7 presses against the steel plate, the setting that the fixed block 7 can slide relatively in the chute is to be applicable to different thicknesses of the steel plate, so that the fixed block 7 can perform bending operations on steel plates of different thicknesses, thereby realizing the diversity of positioning of steel plates of different thicknesses, and thus ensuring the sufficiency of the fixed block 7 to position steel plates of different thicknesses.

[0059] The setting of the gap between the abutting block 2 and the bending block 1 is to facilitate the placement of steel plates of different thicknesses, thereby realizing that this device can position steel plates of different thicknesses, and further ensuring the sufficiency of this device to position steel plates of different thicknesses.

[0060] Therefore, through the relative sliding of the fixed block 7 and the setting of the gap between the abutting block 2 and the bending block 1, it comprehensively ensures that this device can position steel plates of different thicknesses, that is, it improves the practicability of positioning steel plates of different thicknesses.

[0061] During the period when the distance between the two second wedges 9 gradually decreases, the two third racks 39 are abutted against each other, and then the third rack 39 can slide relative to the second wedge 9 in the chamber. During the movement of the third rack 39, since the third rack 39 meshes with the third gear 41, the third gear 41 drives the rotating shaft 40 to rotate. During the rotation of the rotating shaft 40, the worm rotates synchronously.

[0062] During the rotation of the worm, the first gear 35 moves synchronously. During the movement of the first gear 35, since the first gear 35 meshes with the first rack, the first rack can move vertically upward along the length direction of the first guide block 19. Therefore, during the relative sliding between the fixed block 7 and the chute, the first rack drives the side block 17 to move vertically upward through the side plate 18. Therefore, the side block 17 can drive the linkage block 16 to move vertically upward. Through the vertically upward acting force of the linkage block 16, the linkage block 16 can exert a stronger acting force on the steel plate, and then perform a more firm and sufficient positioning on the steel plate, that is, further enhancing the positioning effect on the steel plate and ensuring that the steel plate can remain stable during bending.

[0063] During the positioning of the steel plate under the combined action of the fixed block 7 and the linkage block 16, the worm drives the first screw 22 to rotate through the worm gear 36. During the rotation of the first screw 22, the first screw 22 drives the first nut seat 24 to move vertically upward along the length direction of the first guide rod 23. During the movement of the first nut seat 24, the elastic block 25 moves synchronously. Therefore, while the elastic block 25 moves horizontally along the width direction of the bending block 1, the elastic block 25 can also move vertically upward. Therefore, the elastic block 25 can position different positions of the steel plate, that is, under the abutting action of the elastic block 25, the positioning effect on the steel plate can be further enhanced, and the positioning quality of the steel plate can be improved.

[0064] In summary, through the combined action of the linkage block 16 and the elastic block 25, the steel plate can be firmly fixed at different positions of the steel plate, comprehensively improving the positioning effect and quality of the steel plate.

[0065] During the movement of the second screw 26 following the second wedge block 9, the second screw 26 can rotate under the drive of the first screw 22. As a result, the second nut seat 28 can move vertically downward along the length direction of the second guide rod 27. During the movement of the second nut seat 28, the elastic layer can be gradually compressed, causing the elastic layer to deform. During the deformation of the elastic layer, until the elastic layer moves to the position where the stop groove 31 is located, the elastic layer slides into the stop groove 31 under the action of elastic force. At this time, the first wedge block 6 also stops moving. During the period when the second wedge block 9 stops moving, by the elastic layer being stuck in the stop groove 31, the positioning of the second wedge block 9 is realized, thereby ensuring that the second wedge block 9 will not change its position, enabling the linkage block 16 and the elastic block 25 to efficiently position the steel plate, and further enhancing the positioning effect on the steel plate.

[0066] During the extrusion deformation of the rubber layer 30, the worm drives the second gear 37 to rotate. Then, the second gear 37 meshes with the second rack, and thus the second rack can move vertically downward. Therefore, during the movement of the second rack, the second rack can further cause the elastic layer to deform, enabling the elastic block 25 to efficiently fill into the stop groove 31 when the elastic layer slides into the stop groove 31. Moreover, when the elastic layer is located in the stop groove 31, the pressing block 33 can ensure that the elastic layer will not slide out of the stop groove 31, thereby further enhancing the positioning effect of the elastic layer on the first wedge block 6 and improving the positioning efficiency of the elastic layer.

[0067] After the linkage block 16 and the elastic block 25 have positioned the steel plate, and after the rubber layer 30 has stopped the first wedge block 6, the limiting hole 44 moves to the position where the bolt 43 is located under the push of the third rack 39. The worker inserts the bolt 43 into the limiting hole 44, thereby preventing the limiting block 42 from changing its position under the influence of external environmental factors or human interference.

[0068] Therefore, after the limiting block 42 is positioned by the bolt 43, the linkage block 16 and the elastic block 25 can firmly position the steel plate, and the rubber layer 30 can stably position the second wedge block 9. Furthermore, the stability of the linkage block 16, the elastic block 25, and the rubber layer 30 is enhanced, ensuring that during the positioning of the steel plate by this device, the steel plate can be efficiently and comprehensively positioned, enabling the bending mechanism to perform high-quality bending operations on the steel plate.

[0069] When positioning the limit block 42 with the bolt 43, when the liquid in the jack 11 moves to the position where the insertion block 10 is located, the insertion block 10 is inserted into the jack 11. Therefore, under the action of the insertion block 10, it can be ensured that the push block 8 will not change its position due to human interference or changes in external environmental factors, thereby further ensuring that the linkage block 16 and the elastic layer always stably position the steel plate during the bending of the steel plate, and that the rubber layer 30 fully positions the second wedge block 9, that is, improving the quality of positioning the steel plate.

[0070] In summary, after the steel plate is fixed, the folding block 15 is driven by the cylinder 13 to bend the steel plate, so that the steel plate can be processed into a predetermined folding angle, thereby improving the efficiency of bending the steel plate and ensuring the quality of bending the steel plate.

[0071] Using machinery to replace manual labor to fix the steel plate, on the one hand, enhances the effect of positioning the steel plate and improves the efficiency of positioning the steel plate, and on the other hand, saves unnecessary trouble for workers and saves unnecessary work processes, comprehensively improving the quality of positioning the steel plate.

Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention.

However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
