Description

Technical Field

[0001] This utility model relates to the field of stainless steel plate bending, and specifically to a stainless steel plate bending and forming device. Background Technology

[0002] A bending machine is a type of mechanical equipment used for sheet metal processing. It mainly uses a bending cutter and a die to apply pressure to the metal sheet, causing it to undergo plastic deformation, thereby forming the required bending angle or shape. This process is widely used in the metal processing industry and can efficiently and accurately meet various complex bending requirements.

[0003] In a bending machine, the bending die used for forming is usually fixed inside the die holder by bolts. The die holder is installed on the bending machine table by welding or bolting. Although bolt fixing can provide stable support, in actual production, when it is necessary to change the bending angle of the steel plate, it is necessary to replace the matching die. At this time, the operator needs to frequently tighten or loosen the bolts, which is not only very troublesome, but also requires the equipment to be shut down for a long time, which seriously affects the production efficiency of sheet metal bending.

[0004] Therefore, it is necessary to invent a stainless steel sheet bending and forming device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a stainless steel sheet bending and forming device. Through the cooperation of the locking block and the positioning spring 53, the bending die and the mold seat are quickly locked together after the protrusion and groove are aligned, thus completing the installation of the bending die. By pressing the pressure plate, and simultaneously cooperating with the ball joint rod and the opening slot, the locking block can be pushed, causing it to move out of the locking hole and release its restriction on the protrusion. At this point, the bending die can be removed from the mold seat, thus completing the disassembly of the bending die. This solves the problem of cumbersome, time-consuming, and labor-intensive disassembly and assembly steps for bending dies in the prior art, which reduces the efficiency of sheet metal bending production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel plate bending and forming device, including a mold base, which is installed on the workbench of a bending machine to support the overall device. A bending mold is clamped to the inner wall of the mold base, and bolts are inserted through the inner wall of the mold base. A groove is opened on the inner wall of the mold base, and a protrusion matching the groove is fixedly connected to the side wall of the bending mold.

One end of the locking block is attached to the inner wall of the locking hole, and the other end of the locking block is fixedly connected to a positioning spring. The inner wall of the locking block has an opening groove. A ball joint rod is slidably connected through the inner wall of the mold base. A pressure plate is fixedly connected to the top end of the ball joint rod, and a return spring is fixedly connected to the lower surface of the pressure plate.

[0008] A lifting mechanism, which is located inside the mold base, is used to push the bending mold upward.

[0009] Preferably, the lifting mechanism includes a rotating shaft, which is rotatably connected to the inner wall of the mold base, and a bent rod is fixedly connected to the outer wall of the rotating shaft.

[0010] Preferably, a top rod is fixedly connected to the end of the bent rod away from the pivot.

[0011] Preferably, the inner wall of the mold base is provided with a through hole for inserting the ball head rod, and the through hole and the ball head rod are coaxial.

[0012] Preferably, the end of the reset spring away from the pressure plate is fixedly connected to the upper surface of the mold base, the end of the positioning spring away from the locking block is fixedly connected to the inner wall of the mold base, and the end of the locking block away from the positioning spring has an inclined structure and extends into the interior of the groove.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figures 1-4 The stainless steel sheet bending and forming device shown includes a mold base 1, a disassembly and assembly mechanism 5, and a lifting mechanism 6.

[0025] The mold base 1 is installed on the workbench of the bending machine to support the overall device. The bending die 2 is snapped into the inner wall of the mold base 1. Bolts 3 are inserted through the inner wall of the mold base 1. In use, the mold base 1 is first fixed to the workbench of the bending machine using the bolts 3. The inner wall of the mold base 1 has a groove 4. The side wall of the bending die 2 is fixedly connected to a protrusion 41 that matches the groove 4. The protrusion 41 can be used to limit the axial movement of the bending die 2 by cooperating with the groove 4.

[0026] The disassembly and assembly mechanism 5 includes a locking block 51, which is slidably connected to the inner wall of the mold base 1. A locking hole 52 is provided on the inner wall of the protrusion 41. One end of the locking block 51 fits against the inner wall of the locking hole 52. By engaging the locking block 51 with the locking hole 52, the protrusion 41 can be limited inside the groove 4, thereby limiting the bending die 2 inside the mold base 1. A positioning spring 53 is fixedly connected to the other end of the locking block 51. The end of the positioning spring 53 away from the locking block 51 is fixedly connected to the inner wall of the mold base 1. The elasticity of the positioning spring 53 can cause the locking block 51 to slide and reset on the inner wall of the mold base 1, allowing the locking block 51 to be inserted into the locking hole 52. The end of the locking block 51 away from the positioning spring 53 has a beveled structure and extends into the groove 4. When the protrusion 41 contacts the beveled surface of the locking block 51 during insertion, it pushes the locking block 51, causing it to slide into the mold base 1 and compress the positioning spring 53. The inner wall of the mold base 1 has an opening groove 57. The top and bottom of the opening groove 57 are open structures. The side of the opening groove 57 near the positioning spring 53 is a slope structure, and the side of the opening groove 57 away from the positioning spring 53 is a straight structure perpendicular to the horizontal plane. When the ball head rod 54 slides down and contacts the slope of the opening groove 57, it will push the locking block 51, causing the locking block 51 to slide towards the inner wall of the mold base 1 and compress the positioning spring 53. The inner wall of the mold base 1 is slidably connected to the ball head rod 54. The top of the ball head rod 54 is fixedly connected to the pressure plate 55. Pressing down the pressure plate 55 can drive the ball head rod 54 to slide down the inner wall of the mold base 1. The lower surface of the pressure plate 55 is fixedly connected to the return spring 56. The end of the return spring 56 away from the pressure plate 55 is fixedly connected to the upper surface of the mold base 1. Through the elastic cooperation of the return spring 56 and the pressure plate 55, the ball head rod 54 can slide up and return to its original position on the inner wall of the mold base 1.

[0027] The lifting mechanism 6 is located inside the mold base 1 and is used to push the bending mold 2 upward. The bending mold 2 can be pushed upward out of the mold base 1 by the lifting mechanism 6 so that the operator can manually pick up the bending mold 2 and improve the convenience of changing the bending mold 2.

[0028] like Figures 2-4As shown, the lifting mechanism 6 includes a rotating shaft 61, which is rotatably connected to the inner wall of the mold base 1. A bent rod 62 is fixedly connected to the outer wall of the rotating shaft 61. When the ball head rod 54 presses the bent rod 62 downward, the bent rod 62 will drive the rotating shaft 61 to rotate on the inner wall of the mold base 1. A push rod 63 is fixedly connected to the end of the bent rod 62 away from the rotating shaft 61. While the bent rod 62 drives the rotating shaft 61 to rotate on the inner wall of the mold base 1, the bent rod 62 will drive the push rod 63 to swing upward. By swinging the push rod 63 upward, the bending mold 2 can be pushed upward out of the mold base 1, which makes it convenient for the operator to pick up the bending mold 2. The inner wall of the mold base 1 is provided with a through hole 64 for the ball head rod 54 to be inserted. The through hole 64 and the ball head rod 54 are coaxial. When the bottom end of the ball head rod 54 passes through the through hole 64 and contacts the bent rod 62, the ball head rod 54 will press the bent rod 62 downward.

[0029] The working principle of this utility model is as follows: First, the mold base 1 is fixed to the worktable of the bending machine using bolts 3. Then, the protrusions 41 on both sides of the bending die 2 are aligned with the grooves 4 on the mold base 1, and the bending die 2 is inserted into the mold base 1. This causes the bending die 2 to pull the protrusions 41 into the grooves 4. Simultaneously, when the protrusions 41 contact the inclined surface of the locking block 51 during insertion, they push the locking block 51, causing it to slide into the mold base 1 and compress the positioning spring 53. As the protrusions 41 continue to be inserted, the locking blocks 53 on the protrusions 41... The hole 52 will gradually approach the locking block 51. When the locking hole 52 coincides with the locking block 51, the positioning spring 53 will push the locking block 51 to slide and reset on the inner wall of the mold base 1, so that the locking block 51 can be inserted into the hole 52. At this time, the locking block 51 and the locking hole 52 can limit the protrusion 41 inside the groove 4, thereby limiting the bending die 2 inside the mold base 1. At the same time, the protrusion 41 and the groove 4 can limit the bending die 2 axially, thereby completely fixing the bending die 2 inside the mold base 1, thus completing the installation of the bending die 2.

[0030] When it is necessary to disassemble the bending die 2, press down on the pressure plate 55 to compress the return spring 56 and drive the ball head rod 54 to slide down the inner wall of the die seat 1. When the ball head rod 54 slides down and contacts the inclined surface of the opening groove 57, it will push the locking block 51, causing the locking block 51 to slide towards the inner wall of the die seat 1 and compress the positioning spring 53, so that the locking block 51 can be moved out of the locking hole 52. At this time, the bending die 2 can be taken out from the inside of the die seat 1, thus completing the disassembly of the bending die 2.

[0031] When the ball joint 54 slides down, it pushes the locking block 51 out of the locking hole 52. Then, it continues to press down on the pressure plate 55, causing the pressure plate 55 to drive the ball joint 54 to move downward. At this time, the bottom end of the ball joint 54 will insert into the through hole 64 from the opening at the bottom of the slot 57. When the bottom end of the ball joint 54 passes through the through hole 64 and contacts the bent rod 62, the ball joint 54 will press down on the bent rod 62, causing the bent rod 62 to drive the rotating shaft 61 to rotate on the inner wall of the mold base 1. At the same time, the bent rod 62 will drive the push rod 63 to swing upward. When the push rod 63 contacts the lower surface of the bending die 2 during the upward swing, the push rod 63 will push the bending die 2 upward, causing the bending die 2 to slide upward on the inner wall of the mold base 1. At this time, the push rod 63 can be used to push the bending die 2 upward out of the mold base 1, thereby making it easier for the staff to pick up the bending die 2 and improving the convenience of changing the bending die 2.

[0032] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
