Description

Technical Field

[0001] This utility model relates to the field of steel plate bending technology, and in particular to a steel plate bending device. Background Technology

[0002] The existing forming seat, which is fixedly installed in the steel plate bending device, has forming grooves at different angles on four planes. It cannot be rotated directly. Each time the position of the forming groove is changed according to the bending angle of the steel plate, the forming seat needs to be disassembled and reinstalled, which is time-consuming and results in low working efficiency of the steel plate bending device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a steel plate bending device that solves the problems mentioned in the background section.

[0004] This utility model provides the following technical solution: a steel plate bending device, including a support leg, a support seat fixedly installed on the top of the support leg, a support frame fixedly installed on the outside of the support seat, and a first hydraulic cylinder fixedly fitted inside the support frame. The inner side of the support frame is slidably connected to a mounting seat fixedly installed on the bottom end of the first hydraulic cylinder via a slide rail. A forming blade located above the support seat is fixedly installed on the outer side of the mounting seat. Rotary shafts are rotatably connected to the interior of both sides of the support frame. A forming seat located inside the support seat is provided on the outer side of the rotating shaft. A servo motor fixedly installed on the outer side of the support frame is fixedly sleeved at one end of the rotating shaft extending outside the support frame. A symmetrically distributed limiting mechanism is fixedly installed on the outer side of the support seat.

[0005] Preferably, the limiting mechanism includes a T-shaped limiting block fitted inside the support base and a fixed frame fixedly installed on the outside of the support base. A push plate is provided on one side of the T-shaped limiting block, and a second hydraulic cylinder with one end fixedly connected inside the push plate is fixedly fitted inside the fixed frame.

[0006] Preferably, the support base has a T-shaped guide groove adapted to the T-shaped limiting block and a U-shaped groove adapted to the forming base inside.

[0007] Preferably, the outer side of the molding seat is provided with an arc-shaped surface that matches the U-shaped groove.

[0008] This utility model has the following advantages:

[0009] 1. A single drive of the servo motor can drive the forming seat to rotate 90 degrees around the axis of the rotating shaft, while alternating the forming grooves on the forming seat. Thus, when the device performs bending operations on steel plates at different angles, there is no need to disassemble and install the forming seat, which can reduce the waste of time and improve the working efficiency of the device.

[0010] 2. The second hydraulic cylinder can drive the T-shaped limit block to move, and at the same time, the T-shaped limit block can squeeze and limit the planes on both sides of the forming seat. After the forming seat changes position in the forming groove, the forming seat can be stably limited and fixed by the cooperation of the support seat and the T-shaped limit block, thereby ensuring that the forming seat will not rotate during the bending operation of the steel plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 5A steel plate bending device includes a support leg 1, a support base 2 fixedly installed on the top of the support leg 1, a support frame 3 fixedly installed on the outside of the support base 2, and a first hydraulic cylinder 4 fixedly fitted inside the support frame 3. A mounting seat 6 fixedly installed on the bottom end of the first hydraulic cylinder 4 is slidably connected to the inner side of the support frame 3 via a slide rail 5. The slide rail 5 can limit and guide the mounting seat 6, thereby preventing the forming blade 7 from tilting during the bending process of the steel plate. The forming blade 7, located above the support base 2, is fixedly installed on the outer side of the mounting seat 6. Rotary shafts are rotatably connected to the interior of both sides of the support frame 3. 8. A forming seat 9 is provided on the outer side of the rotating shaft 8 and located inside the support base 2. The forming seat 9 has forming grooves on all four sides and the forming grooves are centered on each side. A servo motor 11 is fixedly connected to the outer side of the supporting frame 3 through a bushing 10 at one end of the rotating shaft 8. The servo motor 11 can drive the forming seat 9 to rotate. When the servo motor 11 is started once, the servo motor 11 can drive the forming seat 9 to rotate 90 degrees around the axis of the rotating shaft 8. A symmetrically distributed limiting mechanism 12 is fixedly installed on the outer side of the support base 2.

[0019] The limiting mechanism 12 includes a T-shaped limiting block 121 fitted inside the support base 2 and a fixed frame 122 fixedly installed on the outside of the support base 2. A push plate 123 is provided on one side of the T-shaped limiting block 121. A second hydraulic cylinder 124 is fixedly fitted inside the fixed frame 122, with one end fixedly connected to the inside of the push plate 123. Driven by the second hydraulic cylinder 124, the push plate 123 can be moved, which in turn moves the T-shaped limiting block 121 synchronously, thereby releasing the limiting of the molding seat 9. At this time, the molding seat 9 can be rotated by the drive of the servo motor 11, and the molding groove can switch positions.

[0020] The support base 2 has a T-shaped guide groove 13 that matches the T-shaped limiting block 121 and a U-shaped groove 14 that matches the forming base 9. The T-shaped guide groove 13 can limit and guide the T-shaped limiting block 121, so that after the drive belt of the second hydraulic cylinder 124 can drive the T-shaped limiting block 121 to press and fix the forming base 9, it can be ensured that the forming base 9 will not rotate around the axis of the rotating shaft 8 during the bending process of the steel plate.

[0021] The outer side of the forming seat 9 is provided with an arc-shaped surface 15 that matches the U-shaped groove 14. The cooperation between the U-shaped groove 14 and the arc-shaped surface 15 ensures that the forming seat 9 will not interfere with the support seat 2 during the rotation of the forming seat 9 around the axis of the rotating shaft 8 under the drive of the servo motor 11. Thus, the support seat 2 can stably support the forming seat 9 and prevent the forming seat 9 from bending and deforming during the bending process of the steel plate.

[0022] Working principle: After placing the steel plate above the forming seat 9, the first hydraulic cylinder 4 is activated. Driven by the first hydraulic cylinder 4, the mounting seat 6 is moved downwards, and the forming blade 7 bends the steel plate. When it is necessary to change the position of the forming groove of the forming seat 9, the second hydraulic cylinder 124 is activated. Driven by the second hydraulic cylinder 124, the T-shaped limit block 121 is moved, and the T-shaped limit block 121 is released from its limit on the forming seat 9. At this time, the servo motor 11 is activated, and driven by the servo motor 11, the forming plate is bent. While the mold base 9 rotates 90 degrees around the axis of the rotating shaft 8, the position of the molding groove is switched. When the switched molding groove is not the required molding groove, the servo motor 11 is started again to drive the molding base 9 to rotate until the required molding groove is rotated to the bottom of the molding knife 7. After the position of the molding groove is adjusted, the second hydraulic cylinder 124 is started. The second hydraulic cylinder 124 drives the T-shaped limit block 121 to move and reset. At the same time, the T-shaped limit block 121 presses and fixes the molding base 9, thus completing the adjustment of the molding groove position.
