Description

Technical Field

[0001] The present invention relates to the technical field of steel frame production, and in particular to a steel structure plate stamping and bending device for producing steel frames. Background Art

[0002] Bending means that the metal sheet first undergoes elastic deformation and then plastic deformation under the pressure of the upper or lower die of the bending machine. In the initial stage of plastic bending, the sheet is free to bend. As the upper or lower die applies pressure to the sheet, the sheet and the inner surface of the V-groove of the lower die gradually come close to each other. At the same time, the radius of curvature and the bending arm gradually become smaller. The pressure is continued until the stroke ends, so that the upper and lower dies and the sheet are in full contact at three points. At this time, a V-shaped bend is completed, which is commonly known as bending. In the fields of construction, decoration, environmental protection, materials, etc., sheet processing is indispensable. During the sheet processing process, it is sometimes necessary to bend according to different sheets. In the prior art, mechanical methods are generally used to bend the sheet. The bending machine is a mechanical equipment often used in bending sheet. The sheet is pressurized by mechanical, pneumatic or hydraulic transmission to bend the sheet into the desired shape along the die.

[0003] At present, when traditional bending equipment uses stamping and bending equipment to bend steel plates, it is necessary to manually pre-position the steel plates, which is inconvenient to operate. Moreover, in the process of stamping and bending the steel plates, the steel plates are not pre-fixed, which can easily cause the steel plates to shift, resulting in a decrease in the stamping quality of the product. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a steel structure plate stamping and bending equipment manufactured by a steel frame, comprising a machine base, the machine base is used for stable support of stamping and bending components, collecting troughs are fixedly installed on both sides of the outer surface of the machine base, an adjustment seat is fixedly installed at the middle of the top of the machine base, a column is fixedly installed on one side of the top of the adjustment seat, a hydraulic cylinder is fixedly installed on the top of the column, and a punch head is movably installed at the bottom of the hydraulic cylinder; A material guide assembly, which is used for guiding and conveying steel plates, and a slide seat is slidably mounted on the bottom of the material guide assembly; A bending assembly, which is used for bending and forming a steel plate; The slide seat is slidably adapted on the top of the adjusting seat, and the bending assembly is slidably installed on the top of the slide seat. The bending assembly and the punching head are arranged on the same central axis. There are two material guide assemblies, and the two material guide assemblies are respectively arranged on both sides of the outer surface of the bending assembly; the staff places the steel plate in the material guide assembly, and pushes the steel plate so that the steel plate slides to one side of the bending assembly in the material guide assembly, and slides to the other side of the material guide assembly. At this time, both ends of the steel plate are located in the material guide assembly, and the staff starts the hydraulic cylinder to move downward to drive the punching head to stamp and bend the steel plate mounted above the bending assembly, so that the steel plate is pressed to be concave and bent downward and squeezed with the bending assembly, so that the bending assembly is displaced by force to facilitate the stamping of the steel plate.

[0005] The guide assembly includes a positioning block, a support rod is fixedly installed on the top of the positioning block, two support rods are provided, and the two support rods are symmetrically arranged with the positioning block as the center, a bottom plate is fixedly installed on the top of the support rod, a round roller is rotatably installed in the middle of the bottom plate, and guide racks are fixedly installed on both sides of the top of the bottom plate. The staff places the steel plate between the bottom plate and the guide rack, and pushes the steel plate to one side of the bending assembly, so that the round roller is driven to rotate when the steel plate is displaced, and is positioned between the bottom plate and the guide rack on the other side, so as to guide and transport the steel plate, so as to facilitate the pre-positioning of the steel plate before stamping and bending.

[0006] Preferably, the guide racks are provided with two groups, and the two groups of guide racks are respectively fixedly mounted on the top two ends of the bottom plate, the positioning block is slidably mounted on the top of the slide, the bottom plate is arranged on both sides of the outer surface of the bending assembly, and the bottom plate is adapted to the bending assembly. The two ends of the steel plate are arranged between the bottom plate and the guide racks, and are mounted above the bending assembly. When the punch head moves downward to punch the steel plate, the pressure point of the steel plate is concave and bent downward. At this time, the two ends of the steel plate between the bottom plate and the guide racks are tilted upward and squeeze the guide racks, so that the guide racks are deformed by force and the two ends of the steel plate are limited to avoid displacement of the plate during punching and bending.

[0007] Preferably, the guide frame includes an external plate, and two external plates are provided. A compression pad is fixedly installed inside the two external plates, and the surface of the compression pad is provided on a segmented round rod. When the steel plate is bent, the two ends are tilted upward and push the compression pad, so that the compression pad is deformed toward one side of the external plate. Since the end of the steel plate is a square structure, when it tilts upward and squeezes the compression pad, the segmented round rod provided on the surface of the compression pad can be covered on its surface according to the shape of the end of the steel plate, so that the compression pad can fit and limit the end of the steel plate, avoiding deviation when the end of the steel plate tilts upward, which affects the bending effect.

The steel plate is mounted in the limiter, and the position where the steel plate contacts the punch head is depressed downward by force when the steel plate is squeezed and bent, and friction is generated with the limiters on both sides when the depression moves downward, so that the limiter and the round shaft rotate toward the middle in the base, and stop rotating when they rotate to contact the spring-loaded part, at which time the reset protection parts on both sides of the limiter are rotated by the limiter.

[0010] Preferably, the base is slidably installed on the top of the slide seat, and limiting parts are rotatably installed on both sides of the top of the base, the limiting parts are adapted to the bottom plate, and reset protective parts are fixedly installed on both sides of the outer surface of the limiting parts, the reset protective parts are fixedly installed on the outer surface of the base, and the limiting parts are extrusion-adapted with the spring-pressing parts.

The steel plate passes through the guide groove and extends into the guide racks on both sides. When the steel plate is bent downward by force, it first contacts the receiving plate. As the punch head moves downward, the middle of the steel plate moves toward the bottom groove, and drives the rotating blocks on both sides to rotate toward the middle when moving downward. When the rotating block rotates to the point where the limiter contacts the spring-pressing member, the rotating block is limited and stops rotating.

When the rotating block rotates, the bent plates on both sides flip upward with it, and the double-ended pipes are driven by the bent rods to rotate on the surface of the connecting plate. After the stamping is completed, the double-ended pipes on both sides of the bent plate rotate downward on the surface of the connecting plate, so that the rotating block is pulled by the bent rods to rotate outward in the base to reset, and when resetting, the steel plate stuck between the rotating blocks after bending is lifted up, so that the steel plate can be taken out of the equipment after bending.

[0015] The present invention provides a steel structure plate stamping and bending device for manufacturing steel structures. It has the following beneficial effects: 1. The steel structure plate stamping and bending equipment manufactured by the steel structure is arranged between the bottom plate and the guide frame through the two ends of the steel plate, and is erected above the bending component. When the punch head moves downward to punch the steel plate, the pressure point of the steel plate is concave and bent downward. At this time, the two ends of the steel plate between the bottom plate and the guide frame are tilted upward and squeeze the guide frame, so that the guide frame is deformed by the force and limits the two ends of the steel plate to avoid displacement of the plate during stamping and bending.

[0016] 2. The steel structure plate stamping and bending equipment manufactured by the steel structure, when the two ends of the steel plate are bent, they are lifted up and the extrusion pad is pushed up, so that the extrusion pad is deformed toward the side of the external plate. Since the end of the steel plate is a square structure, when it is lifted up and the extrusion pad is extruded, the segmented round rods arranged on the surface of the extrusion pad can be covered on its surface according to the shape of the end of the steel plate, so that the extrusion pad can fit and limit the end of the steel plate to avoid displacement when the end of the steel plate is lifted up, which affects the bending effect.

[0017] 3. The steel structure plate stamping and bending equipment manufactured by the steel structure extends through the guide groove on both sides of the guide frame. When the steel plate is bent downward by force, it first contacts the receiving plate. As the punching head moves downward, the middle of the steel plate moves toward the bottom groove, and drives the rotating blocks on both sides to rotate toward the middle when moving downward. When the rotating block rotates to the limit block and contacts the spring-pressing part, the rotating block is limited and stops rotating. The spring-pressing part is set to an elastic structure to prevent creases on the surface of the steel plate caused by excessive punching pressure of the punching head.

[0018] 4. The steel structure plate stamping and bending equipment manufactured by the steel frame, when the rotating block rotates, the bent plates on both sides flip upward with it, and the double-headed pipe is driven to rotate on the surface of the connecting plate by the bending rod. After the stamping is completed, the double-headed pipe on both sides of the bent plate rotates downward on the surface of the connecting plate, so that the rotating block is pulled by the bending rod to rotate outward in the base and reset, and when resetting, the steel plate stuck between the rotating blocks after bending is lifted up, so that the steel plate can be removed from the equipment after bending.

[0019] 5. The steel structure plate stamping and bending equipment manufactured by the steel frame production collides with the outer side of the connecting plate when the double-headed pipe is rotated and reset. At this time, the elastic rod connected to the bottom of the connecting block is deformed by the impact to cushion the double-headed pipe. BRIEF DESCRIPTION OF THE DRAWINGS

The bending component 3 and the punch head 9 are arranged on the same central axis. There are two material guide components 8, and the two material guide components 8 are respectively arranged on both sides of the outer surface of the bending component 3; the staff places the steel plate in the material guide component 8, and pushes the steel plate so that the steel plate slides in the material guide component 8 to one side of the bending component 3, and slides to the other side of the material guide component 8. At this time, both ends of the steel plate are located in the material guide component 8. The staff starts the hydraulic cylinder 2 to move downward to drive the punch head 9 to stamp and bend the steel plate mounted above the bending component 3, so that the steel plate is pressed to be concave and bent downward and squeezed with the bending component 3, so that the bending component 3 is displaced by force to facilitate the stamping of the steel plate.

[0024] The bending assembly 3 includes a base 33, a bottom groove 36 is provided in the middle of the base 33, a spring-loaded part 34 is movably installed in the middle of the bottom groove 36, a round shaft 35 is passed through the base 33, and the round shaft 35 is rotatably adapted to the base 33. The steel plate is mounted in the limiter 31, and the position where the steel plate contacts the punch head 9 is depressed downward by force when the steel plate is squeezed and bent, and friction is generated with the limiters 31 on both sides when the depression moves downward, so that the limiter 31 and the round shaft 35 rotate toward the middle in the base 33, and stop rotating when they rotate to contact the spring-loaded part 34, at which time the reset protection parts 32 on both sides of the limiter 31 are pulled by the limiter 31 to rotate.

[0025] The base 33 is slidably installed on the top of the slide seat 4, and the limiting members 31 are rotatably installed on both sides of the top of the base 33. The limiting members 31 are adapted to the bottom plate 85. Reset protective members 32 are fixedly installed on both sides of the outer surface of the limiting member 31. The reset protective member 32 is fixedly installed on the outer surface of the base 33, and the limiting member 31 is extruded and adapted to the spring-pressing member 34.

[0026] The second embodiment is based on the first embodiment. Figures 4 to 5 As shown, The limiting member 31 includes a rotating block 314, a receiving plate 313 is arranged on the top of the rotating block 314, a limiting block 315 is fixedly installed on the surface of the rotating block 314 away from the receiving plate 313, a bent plate 312 is fixedly installed on the outer surface of the receiving plate 313, and a guide groove 311 is opened in the middle of the outer surface of the bent plate 312. The steel plate passes through the guide groove 311 and extends into the guide racks 81 on both sides. When the steel plate is bent downward by force, it first contacts the receiving plate 313. As the punch head 9 moves downward, the middle of the steel plate moves toward the bottom groove 36, and drives the rotating blocks 314 on both sides to rotate toward the middle when moving downward. When the rotating block 314 rotates to the limiting block 315 and contacts the spring-pressing member 34, the rotating block 314 is limited and stops rotating. The spring-pressing member 34 is set as an elastic structure to prevent the punch head 9 from causing creases on the surface of the steel plate due to excessive punching pressure.

[0027] The guide groove 311 is connected to the bottom plate 85 , the rotating block 314 is rotatably mounted on both sides of the top of the base 33 , the limiting block 315 is extruded and adapted to the elastic member 34 , and the bent plate 312 is fixedly connected to the reset protective member 32 .

[0028] The reset guard 32 includes a bent rod 321, which is fixedly mounted on the outer surface of the bent plate 312. Two bent rods 321 are provided, and double-ended pipes 323 are fixedly mounted on the outer surfaces of the two bent rods 321. Springs 322 are fixedly mounted on both ends of the outer surfaces of the double-ended pipes 323, and a connecting plate 324 is rotatably mounted on the surface of the spring 322. When the rotating block 314 rotates, the bent plates 312 on both sides flip upward with it, and the double-ended pipes 323 are driven by the bent rods 321 to rotate on the surface of the connecting plate 324. After the stamping is completed, the double-ended pipes 323 on both sides of the bent plate 312 rotate downward on the surface of the connecting plate 324, so that the rotating block 314 is pulled by the bent rods 321 to rotate outward in the base 33 to reset, and when resetting, the steel plate stuck between the rotating blocks 314 after bending is lifted up, so that the steel plate can be taken out of the equipment after bending.

[0029] The outer surface of the connecting plate 324 is fixedly mounted with a connecting block 325, and the surface of the connecting block 325 is fixedly mounted with an elastic rod 326, and the surface of the elastic rod 326 is fixedly mounted with an extension rod 327, and the outer surface of the extension rod 327 is fixedly mounted with a fixing seat 328, and the fixing seat 328 is fixedly mounted on the outer surface of the base 33. When the double-ended pipe 323 rotates and resets, it collides with the outer side of the connecting plate 324, and at this time, the elastic rod 326 connected to the bottom of the connecting block 325 is deformed by the impact to buffer the double-ended pipe 323.

[0030] The third embodiment is based on the first and second embodiments. Figures 6 to 9 As shown, the guide assembly 8 includes a positioning block 82, a support rod 84 is fixedly installed on the top of the positioning block 82, two support rods 84 are provided, and the two support rods 84 are symmetrically arranged with the positioning block 82 as the center, a bottom plate 85 is fixedly installed on the top of the support rod 84, a round roller 83 is rotatably installed in the middle of the bottom plate 85, and guide racks 81 are fixedly installed on both sides of the top of the bottom plate 85. The staff places the steel plate between the bottom plate 85 and the guide rack 81, and pushes the steel plate to one side of the bending assembly 3, so that the round roller 83 is driven to rotate when the steel plate is displaced, and is positioned between the bottom plate 85 and the guide rack 81 on the other side, so as to guide and convey the steel plate, so as to facilitate the pre-positioning of the steel plate before stamping and bending.

[0031] The guide racks 81 are provided with two groups, and the two groups of guide racks 81 are fixedly mounted on the top two ends of the bottom plate 85, respectively. The positioning block 82 is slidably mounted on the top of the slide 4. The bottom plate 85 is arranged on both sides of the outer surface of the bending assembly 3, and the bottom plate 85 is adapted to the bending assembly 3. The two ends of the steel plate are arranged between the bottom plate 85 and the guide rack 81, and are mounted above the bending assembly 3. When the punch head 9 moves downward to punch the steel plate, the pressure point of the steel plate is concave and bent downward. At this time, the two ends of the steel plate between the bottom plate 85 and the guide rack 81 are tilted upward, and the guide rack 81 is squeezed, so that the guide rack 81 is deformed by force and the two ends of the steel plate are limited to avoid displacement of the plate during punching and bending.

[0032] The guide frame 81 includes an external plate 813, and two external plates 813 are provided. A compression pad 812 is fixedly installed inside the two external plates 813, and the surface of the compression pad 812 is provided on a segmented round rod 814. When the steel plate is bent, the two ends are tilted upward and push the compression pad 812, so that the compression pad 812 is deformed toward one side of the external plate 813. Since the end of the steel plate is a square structure, when it tilts upward and squeezes the compression pad 812, the segmented round rod 814 provided on the surface of the compression pad 812 can be covered on its surface according to the shape of the end of the steel plate, so that the compression pad 812 can fit and limit the end of the steel plate, so as to avoid deviation when the end of the steel plate tilts upward, which affects the bending effect.

[0033] A slot 815 is provided in the middle of the outer surface of the compression pad 812, and a limiting plate 811 is fixedly installed between the opposite surfaces of the slot 815. The surface of the external plate 813 is fixedly installed on the top side of the bottom plate 85, and the limiting plate 811 is mounted on the top of the round roller 83 through the slot 815.

[0034] When in use, the staff places the steel plate in the material guide assembly 8 and pushes the steel plate so that the steel plate slides in the material guide assembly 8 toward one side of the bending assembly 3 and slides into the material guide assembly 8 on the other side. At this time, both ends of the steel plate are located in the material guide assembly 8. The staff starts the hydraulic cylinder 2 to move downward to drive the punch head 9 to punch and bend the steel plate mounted above the bending assembly 3, so that the steel plate is pressed to be concave and bent downward and squeezed with the bending assembly 3, so that the bending assembly 3 is displaced by force to facilitate the stamping of the steel plate.

[0035] The staff places the steel plate between the bottom plate 85 and the guide rack 81, and pushes the steel plate toward one side of the bending assembly 3, so that the round roller 83 is driven to rotate when the steel plate is displaced, and is positioned between the bottom plate 85 and the guide rack 81 on the other side to guide and transport the steel plate, so as to facilitate pre-positioning of the steel plate before stamping and bending.

[0036] The two ends of the steel plate are arranged between the bottom plate 85 and the guide frame 81, and are mounted above the bending assembly 3. When the punch head 9 moves downward to punch the steel plate, the pressure point of the steel plate bends downward. At this time, the two ends of the steel plate between the bottom plate 85 and the guide frame 81 are tilted upward and squeeze the guide frame 81, so that the guide frame 81 is deformed by the force and the two ends of the steel plate are limited to avoid displacement of the plate during stamping and bending.

[0037] When the steel plate is bent, both ends tilt upward and push the compression pad 812, causing the compression pad 812 to deform toward the side of the external plate 813. Since the end of the steel plate is a square structure, when it tilts upward and squeezes the compression pad 812, the segmented round rod 814 arranged on the surface of the compression pad 812 can be wrapped around its surface according to the shape of the end of the steel plate, so that the compression pad 812 can fit and limit the end of the steel plate to avoid displacement when the end of the steel plate tilts upward, affecting the bending effect.

[0038] The steel plate is mounted in the limiter 31. When the steel plate is squeezed and bent, the position in contact with the punch head 9 is depressed downward by force, and when the depression moves downward, friction is generated with the limiters 31 on both sides, so that the limiter 31 and the circular shaft 35 rotate toward the middle in the base 33, and stop rotating when they contact the spring-pressing member 34. At this time, the reset protective members 32 on both sides of the limiter 31 are rotated by the limiter 31.

[0039] The steel plate passes through the guide groove 311 and extends into the guide racks 81 on both sides. When the steel plate is bent downward by force, it first contacts the receiving plate 313. As the punch head 9 moves downward, the middle of the steel plate moves toward the side of the bottom groove 36, and drives the rotating blocks 314 on both sides to rotate toward the middle when moving downward. When the rotating block 314 rotates to the limit block 315 and contacts the spring-pressing piece 34, the rotating block 314 is limited and stops rotating. The spring-pressing piece 34 is set to an elastic structure to prevent creases from appearing on the surface of the steel plate due to excessive punching pressure of the punch head 9.

[0040] When the rotating block 314 rotates, the bent plates 312 on both sides flip upward with it, and drive the double-headed pipe 323 to rotate on the surface of the connecting plate 324 through the bent rod 321. After the stamping is completed, the double-headed pipe 323 on both sides of the bent plate 312 rotates downward on the surface of the connecting plate 324, so that the rotating block 314 is pulled by the bent rod 321 to rotate outward inside the base 33 to reset, and when resetting, the steel plate stuck between the rotating blocks 314 after being bent is lifted up to facilitate the removal of the steel plate from the equipment after being bent.

[0041] When the double-ended pipe 323 rotates and resets, it collides with the outer side of the connecting plate 324 . At this time, the elastic rod 326 connected to the bottom of the connecting block 325 is deformed by the impact to buffer the double-ended pipe 323 .

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
