Description

Technical Field

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

[0002] The U-shaped steel plate is a metal structural member. Usually, it is processed by stamping a U-shaped groove structure in the middle of the steel plate, that is, first heating the steel plate, then placing the steel plate on a stamping machine tool. There is a stamping groove on the stamping machine tool, and the steel plate is stamped by a stamping head to form a U-shaped steel plate. Before stamping the steel plate with a traditional stamping and forming device, it is necessary to fix the steel plate. Usually, the position of the positioning plate is adjusted by bolts to tighten the steel plate. When the lengths of the steel plates to be processed are different, it is necessary to disassemble and assemble the bolts to replace the positioning plates with different widths. Therefore, it is necessary to prepare positioning plates of different sizes, resulting in increased costs and very inconvenient operation.

[0003] To solve the above problems, a Chinese patent with the publication number CN216441427U discloses a device for stamping steel plates, including a stamping machine tool. There is a stamping groove on the stamping machine tool. An elevating member is arranged above the stamping groove of the stamping machine tool. The driving end of the elevating member is provided with a stamping head. Positioning plates for abutting and positioning both ends of the steel plate in the length direction are arranged on both sides of the stamping groove of the stamping machine tool. The positioning plates are slidably arranged on the stamping machine tool along the length direction of the steel plate, and a first fixing member for fixing itself is arranged on the positioning plates; this device can quickly adjust the position of the positioning plates according to the length of the steel plate to fix the steel plate, and the operation is more convenient; moreover, there is no need to prepare multiple positioning plates of different sizes, saving costs.

[0004] The following problems exist during the actual use of the above device: The single-side positioning of the steel plate requires adjusting the limit plate, the first fixing member, and the second fixing member, and the operation is very cumbersome; moreover, both sides of the steel plate need to be positioned, so the operation needs to be repeated, making the operation more cumbersome and the work efficiency low. Summary of the Invention

[0005] The present invention aims to provide a steel plate stamping and forming device to solve the problem of cumbersome operation in the positioning method of the existing device for steel plates.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A steel plate stamping and forming device includes a base. A groove is provided in the middle of the base. Chutes are provided on both sides of the base located in the groove. Sliders are slidably connected in the chutes. A vertical groove is provided on the sliders. An elevating block is slidably connected in the vertical groove; a first inclined groove is provided in the chute. A first auxiliary block is slidably connected in the first inclined groove. The first auxiliary block is fixedly connected to the elevating block; a pressing mechanism for pressing the steel plate is provided on the elevating block; it also includes an adjusting mechanism for adjusting the distance between the two sliders and a stamping mechanism for extruding the steel plate into the groove.

[0007] The principle and advantages of this solution are as follows: In this solution, the steel plate is placed on the base such that the middle part of the steel plate is above the groove; through the adjusting mechanism, the distance between the two sliders is reduced, that is, the two sliders are made to approach each other. During the lateral movement of the sliders, the sliders drive the lifting blocks to move synchronously. During the movement of the lifting blocks along the path of the first inclined groove through the first auxiliary blocks, the lifting blocks will also move downward, and then the pressing mechanism presses the steel plate. Then, the stamping mechanism squeezes the middle part of the steel plate into the groove to form a U-shaped steel plate. Compared with the prior art, this solution realizes the linkage positioning of the steel plate through the adjusting mechanism, with simpler operation and improved work efficiency.

[0008] Furthermore, the pressing mechanism includes a pressing block and a U-shaped block fixedly connected to the top of the lifting block. The U-shaped block can move horizontally and vertically in the sliding groove. A rotating shaft is rotatably connected to the U-shaped block, and a torsion spring is provided between the rotating shaft and the U-shaped block. An active block is coaxially connected to the rotating shaft, and the pressing block is connected to the active block.

[0009] Through the above settings, the steel plate is placed on the base such that the middle part of the steel plate is directly above the groove; the two ends of the steel plate respectively pass through the U-shaped blocks on both sides, that is, the ends of the steel plate are located between the two ends of the U-shaped blocks; and, the ends of the steel plate are located below the active block and the pressing block.

[0010] During the lateral movement of the lifting block, the lifting block will also move downward. The lifting block drives the U-shaped block to move synchronously, and the U-shaped block drives the active block and the pressing block to move synchronously, so that the pressing block abuts against the top of the steel plate, thereby realizing the pressing of the steel plate, that is, realizing the preliminary positioning of the steel plate.

[0011] Furthermore, side blocks are provided at both ends of the U-shaped block, and a first elastic layer for abutting against the steel plate is provided on the side blocks.

[0012] Through the above settings, during the downward movement of the U-shaped block, the U-shaped block drives the side blocks and the first elastic layer to move synchronously. When the arc surface on the pressing block abuts against the top of the steel plate, the first elastic layer abuts against the top of the steel plate, thereby realizing the pressing of the pressing plate and further strengthening the positioning effect of the steel plate.

[0013] Since the first elastic layer abuts against the steel plate, during the lateral movement of the end of the steel plate, the friction between the first elastic layer and the steel plate can promote the more stable movement of the end of the steel plate, and thus the precision of the forming of the U-shaped steel plate.

[0014] Furthermore, the adjusting mechanism includes a chamber opened in the base, a bidirectional screw rotatably connected to the chamber, and a driving part for driving the bidirectional screw to rotate. The chamber communicates with the sliding groove, and the two sliders are respectively threadedly connected to the two ends of the bidirectional screw, and the sliders can move horizontally in the chamber.

[0015] With the above settings, the driving part drives the bidirectional screw to rotate, reducing the distance between the two sliders, that is, bringing the two sliders closer together.

[0016] Furthermore, the stamping mechanism includes a support base fixedly connected to the base and a stamping part for extruding the steel plate into the groove. A first cylinder is provided on the support base, and a bearing plate is fixedly connected to the output shaft of the first cylinder. The stamping part is arranged on the bearing plate and is located directly above the groove.

[0017] With the above settings, the output shaft of the first cylinder drives the bearing plate to move downward, bringing the stamping part closer to the steel plate, and using the stamping part to stamp and form the steel plate.

[0018] Furthermore, the movable block can rotate between the two side blocks; the pressing block is vertically slidably connected to the movable block, and a first spring is provided between the pressing block and the movable block; an arc surface is provided at the bottom of the pressing block, a panel is provided at the top of the pressing block, and a second elastic layer for abutting against the steel plate is provided on the panel; push blocks are provided on both sides of the bottom of the bearing plate, and the arc surface is located on the movement track of the push blocks; a linkage mechanism is further included which drives the two rotating shafts to rotate simultaneously as the bearing plate moves vertically, and the rotating directions of the two rotating shafts are opposite.

[0019] With the above settings, during the downward movement of the bearing plate, the two rotating shafts are driven to rotate by the linkage mechanism, and the rotating directions of the two rotating shafts are opposite; the rotating shafts drive the movable block to rotate 180 degrees, and the torsion spring deforms; during the rotation of the movable block, the movable block drives the pressing block, the panel, the vertical plate, and the anti-deviation block to move synchronously, making the arc surface of the pressing block face upward and the panel face, that is, the panel faces the steel plate direction.

[0020] During the downward movement of the bearing plate, the bearing plate drives the push blocks to move downward, and the push blocks squeeze the arc surface of the pressing block to move downward, causing the extrusion block to drive the panel and the second elastic layer to move downward, and the second elastic layer abuts against the top of the steel plate, thereby achieving the pressing of the steel plate.

[0021] Since the second elastic layer abuts against the steel plate, during the lateral movement of the end of the steel plate, the friction force between the second elastic layer and the steel plate can make the movement of the end of the steel plate smoother, and further improve the precision of the U-shaped steel plate forming.

[0022] Furthermore, the linkage mechanism includes linkage parts on both sides of the bottom of the bearing plate, gears coaxially connected to the rotating shafts, and stop holes opened on the rotating shafts. The linkage parts include racks fixedly connected to the bearing plate and stop blocks. The gears are located on the movement track of the racks, the racks can mesh with the gears, the stop holes are located on the movement track of the stop blocks, and the stop blocks are slidably matched with the stop holes.

[0023] With the above settings, during the downward movement of the bearing plate, the bearing plate drives the rack, the stop block, and the push block to move downward synchronously, causing the rack to engage with the gear first and drive the gear to rotate. The gear drives the rotating shaft to rotate, and the rotating shaft drives the movable block to rotate 180 degrees, deforming the torsion spring. During the rotation of the movable block, the movable block drives the pressing block and the panel to move synchronously, making the arc surface of the pressing block face upward and the panel face downward, that is, the panel faces the steel plate. When the movable block rotates 180 degrees, the rack and the gear are no longer engaged, that is, the rack can no longer drive the gear to rotate. At the same time, the stop block extends into the stop hole to stop the rotating shaft and prevent it from rotating further, keeping the positions of the pressing block and the panel unchanged. Then, the rack, the stop block, and the push block continue to move downward, and the push block squeezes the arc surface on the pressing block to move downward, compressing the first spring. During the downward movement of the pressing block, the pressing block drives the panel and the second elastic layer to move synchronously, making the second elastic layer abut against the top of the steel plate to achieve the pressing of the steel plate.

[0024] Furthermore, a vertical plate is provided on the movable block, and second inclined grooves are provided on both sides of the side wall of the vertical plate. Second auxiliary blocks are slidably connected in the second inclined grooves. Guide grooves are provided on both sides of the top of the panel, and anti-deviation blocks are slidably connected in the guide grooves. A second spring is provided between the anti-deviation blocks and the guide grooves, and a third elastic layer for abutting against the steel plate is provided on the side wall of the anti-deviation blocks. The second auxiliary blocks are fixedly connected to the anti-deviation blocks.

[0025] With the above settings, during the movement of the movable block, the movable block drives the vertical plate to move synchronously. During the downward movement of the panel, the panel drives the two anti-deviation blocks to move downward as well. The anti-deviation blocks will also move horizontally along the path of the second inclined grooves through the second auxiliary blocks, stretching the second spring, that is, making the two anti-deviation blocks approach, that is, the two third elastic layers approach. When the second elastic layer abuts against the top of the steel plate, the two third elastic layers abut against both sides of the steel plate to achieve the limit of the steel plate.

[0026] During the deformation of the middle part of the steel plate extending into the groove, both ends of the steel plate move towards the middle part of the steel plate. Since the first elastic layer, the second elastic layer, and the third elastic layer all abut against the steel plate, during the transverse movement of the end of the steel plate, the friction between the first elastic layer, the second elastic layer, and the third elastic layer and the steel plate can promote the movement of the end of the steel plate to be more stable, thereby improving the forming accuracy of the U-shaped steel plate. Moreover, the friction contact between the third elastic layers on both sides of the end of the steel plate and the steel plate can prevent the end of the steel plate from shifting during the movement process, further ensuring the forming accuracy of the U-shaped steel plate.

[0027] Furthermore, the stamping part includes a stamping head and a second cylinder fixedly connected to the bearing plate. The output shaft of the second cylinder is fixedly connected to the stamping head, and the stamping head is located directly above the groove.

[0028] With the above settings, the output shaft of the second cylinder drives the stamping head to move downward, so that the stamping head extrudes the middle part of the steel plate to deform and extend into the groove, thereby forming a U-shaped steel plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The specific implementation process is as follows:

[0042] During use, the steel plate is placed on the base 10 such that the middle part of the steel plate is directly above the groove 11; the two ends of the steel plate respectively pass through the U-shaped blocks 21 on both sides, that is, the end parts of the steel plate are located between the two ends of the U-shaped blocks 21; and the end parts of the steel plate are located below the movable block 23 and the pressing block 20.

[0043] Start the motor 32. The output shaft of the motor 32 drives the bidirectional screw 31 to rotate, causing the two sliders 12 to move horizontally and approach each other. During the horizontal movement of the sliders 12, the sliders 12 drive the lifting blocks 13 to move synchronously. The lifting blocks 13 will also move downward along the path of the first inclined groove 14 through the first auxiliary block. The lifting blocks 13 drive the U-shaped blocks 21 to move downward, and the U-shaped blocks 21 drive the movable blocks 23 and the pressing blocks 20 to move downward. When the arc surface 27 on the pressing block 20 abuts against the top of the steel plate, turn off the motor 32, thereby realizing the positioning of the bidirectional screw 31, and then positioning the pressing block 20 through the sliders 12, the lifting blocks 13, the U-shaped blocks 21, and the movable blocks 23, and further realizing the pressing of the steel plate, that is, realizing the preliminary positioning of the steel plate.

[0044] During the downward movement of the U-shaped block 21, the U-shaped block 21 drives the side blocks 24 and the first elastic layer 25 to move synchronously. When the arc surface 27 on the pressing block 20 abuts against the top of the steel plate, the first elastic layer 25 abuts against the top of the steel plate, thereby realizing the pressing of the pressing plate and further strengthening the positioning effect of the steel plate.

[0045] After completing the preliminary positioning of the steel plate, start the first cylinder 41. The output shaft of the first cylinder 41 drives the bearing plate 42 to move downward, and then drives the punching head 43 to move downward, making the punching head 43 approach the steel plate. During the downward movement of the bearing plate 42, the bearing plate 42 drives the rack 54, the stop block 55 and the push block 52 to move downward synchronously, so that the rack 54 first meshes with the gear 53 to drive the gear 53 to rotate. The gear 53 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the movable block 23 to rotate 180 degrees, and the torsion spring deforms. During the rotation of the movable block 23, the movable block 23 drives the pressing block 20, the panel 50, the vertical plate 60, and the anti-deviation block 62 to move synchronously, so that the arc surface 27 of the pressing block 20 faces upward and the panel 50 faces downward, that is, the panel 50 faces the steel plate direction. When the movable block 23 rotates 180 degrees, the rack 54 and the gear 53 are no longer meshed, that is, the rack 54 can no longer drive the gear 53 to rotate. At the same time, the stop block 55 extends into the stop hole, thereby being able to stop the rotating shaft 22 and prevent the rotating shaft 22 from rotating again, so that the positions of the pressing block 20 and the panel 50 remain unchanged. After that, the rack 54, the stop block 55 and the push block 52 continue to move downward, and the push block 52 squeezes the arc surface 27 on the pressing block 20 to move downward, and the first spring 26 is compressed. During the downward movement of the pressing block 20, the pressing block 20 drives the panel 50 and the second elastic layer 51 to move synchronously. When the second elastic layer 51 abuts against the top of the steel plate, turn off the first cylinder 41, thereby realizing the positioning of the bearing plate 42, and then realizing the positioning of the rack 54, the stop block 55 and the push block 52, that is, the push block 52 presses the top of the steel plate through the pressing block 20, the panel 50, and the second elastic layer 51.

[0046] In the initial state, the distance between the two second inclined grooves 61 gradually increases from top to bottom. After the movable block 23 rotates 180 degrees, the vertical plate 60 also rotates 180 degrees, so that the distance between the two second inclined grooves 61 on the vertical plate 60 gradually decreases from top to bottom at this time. Therefore, during the downward movement of the panel 50, the panel 50 drives the two anti-deviation blocks 62 to move downward as well. The anti-deviation blocks 62 will also move horizontally along the path of the second inclined groove 61 through the second auxiliary block, and the second spring 63 is stretched, that is, the two anti-deviation blocks 62 are brought closer, that is, the two third elastic layers 64 are brought closer. When the second elastic layer 51 abuts against the top of the steel plate, the two third elastic layers 64 abut against both sides of the steel plate, so as to realize the limit of the steel plate.

[0047] After the positioning of the bearing plate 42 is completed, the second cylinder 44 is started. The output shaft of the second cylinder 44 drives the stamping head 43 to move downward, so that the stamping head 43 squeezes the middle part of the steel plate to deform and extend into the groove 11, thereby forming a U-shaped steel plate. During the deformation of the middle part of the steel plate extending into the groove 11, both ends of the steel plate move towards the middle of the steel plate. Since the first elastic layer 25, the second elastic layer 51, and the third elastic layer 64 all abut against the steel plate, during the transverse movement of the end of the steel plate, the friction between the first elastic layer 25, the second elastic layer 51, the third elastic layer 64 and the steel plate can make the movement of the end of the steel plate more stable, and thus the precision of the formed U-shaped steel plate; moreover, the friction contact between the third elastic layer 64 on both sides of the end of the steel plate and the steel plate can prevent the end of the steel plate from shifting during the movement process, further ensuring the precision of the formed U-shaped steel plate.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
