Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an adjustable bending mold. Background Art

[0002] A press-bending die is a tool used for metal processing. It is mainly used to apply pressure on metal sheets or pipes to make them bend and deform. The press-bending die usually consists of an upper die and a lower die. The bending process of the metal material is completed through the pressure between the two.

[0003] Referring to the existing patent publication number: CN209680931U, an adjustable press-bending die comprises an upper die base and a lower die base, the upper die base comprises a template upper plate, a connecting block and a punch, the template upper plate is welded to the connecting block, the connecting block and the punch are movably connected through a T-slot, the lower die base comprises a template bottom plate, a support plate, an adjusting block, a pressure plate and a sliding block, the template bottom plate and the supporting plate are welded into one, for a variety of bending R-angle arcs and opening sizes of similar workpieces, only the upper and lower die bases need to be clamped once, and the bending parameters can be changed by replacing the upper die base punch and adjusting the lower die base adjusting block, thereby realizing multiple uses of one die, reducing the time for repeated mold replacement, improving work efficiency, and reducing safety hazards.

[0004] However, in actual use, the existing press-bending dies usually require certain support at the bottom of the workpiece when the workpiece is press-bent. When the above-mentioned application document supports the workpiece through a sliding block to change the sliding friction into rolling friction, the workpiece lacks certain limitations, which makes it easy for the workpiece to slip on its surface and has poor stability, thereby affecting the press-bending operation and the pressing effect.

The utility model can limit the workpiece to be bent to a certain extent through the limiting part to reduce the range of movement of the workpiece and avoid large slippage during the bending operation to affect the bending operation and the bending effect. In addition, an adjustment mechanism is provided at the bottom to adjust the distance between the limiting parts to limit the workpieces of different specifications and improve the use effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0033] Reference Figure 1-4 , an adjustable bending mold, comprising: a lower mold base 1 and an upper mold base 2, which are arranged in a split manner and combined to form a mold as a whole; a bearing member 6, which is movably installed on the upper part of the lower mold base 1; a rotating member 9, which is rotatably connected to the upper part of the bearing member 6 through a bearing; a limiting part 10, which is a group of two and symmetrically distributed along the longitudinal center line of the rotating member 9 and sleeved on the surface of the rotating member 9, so that the rotating member 9 can rotate normally and avoid interference with the movement of the limiting part 10; an adjusting mechanism located below the rotating member 9 and used to drive the limiting part 10 to move is installed inside the bearing member 6, and the distance between the limiting parts 10 can be adjusted by the adjusting mechanism, so that the limiting part 10 can limit workpieces of different specifications, thereby improving the use effect and application scope of the limiting part 10, and a driving mechanism for driving the bearing member 6 to move is installed inside the lower mold base 1, and the bearing member 6 can be driven to move by the driving mechanism, thereby adjusting the distance between the bearing members 6 to bend into different shapes for easy adjustment.

[0034] Specifically, refer to Figure 2-3The adjusting mechanism comprises: a first slide groove 11, a first bidirectional screw rod 12, a first threaded sleeve 13 and an operating part 5; the first slide groove 11 is opened at the upper part of the bearing member 6, the first bidirectional screw rod 12 is connected to the inside of the first slide groove 11, and the first threaded sleeve 13 is adapted to the first slide groove 11 and installed on both sides of the surface of the first bidirectional screw rod 12. The operating part 5 is installed at one end of the first bidirectional screw rod 12 and is located outside the bearing member 6. After the above-mentioned adjusting mechanism is installed, through this embodiment, the personnel can rotate the operating part 5 so that the operating part 5 can drive the first bidirectional screw rod 12 to rotate, and the first bidirectional screw rod 12 drives the first threaded sleeve 13 to move in the first slide groove 11, thereby gradually transmitting the action. Further, the first threaded sleeve 13 is connected and installed with the limiting part 10 and corresponds to it. The first threaded sleeve 13 can drive the limiting parts 10 in a group to move away from or close to each other to adjust the distance between them, thereby limiting the processing of workpieces of different specifications and improving the use effect.

[0035] Specifically, refer to Figure 4 The driving mechanism includes: a motor 16, a second slide groove 17, a second bidirectional screw rod 14 and a second threaded sleeve 15; the motor 16 is installed at one end of the lower die base 1, the second slide groove 17 is opened at the upper part of the lower die base 1, the second bidirectional screw rod 14 is connected to the output end of the motor 16 and passes through the lower die base 1 and extends into the second slide groove 17, and the second threaded sleeves 15 are adapted to the second slide groove 17 and installed on both sides of the surface of the second bidirectional screw rod 14. Through this embodiment, the motor 16 can be started so that the motor 16 can drive the second bidirectional screw rod 14 to rotate after working, and the second bidirectional screw rod 14 will drive the second threaded sleeve 15 to slide in the second slide groove 17 after rotating. Further, the driving mechanism can also be but not limited to a cylinder, an electric cylinder or a hydraulic cylinder and other components that can drive the bearing member 6 to move horizontally, so as to adjust the relative distance of the bearing member 6.

[0036] Furthermore, the upper part of the second threaded sleeve 15 is connected and installed with the supporting member 6. Through this implementation, the second threaded sleeve 15 can drive the two supporting members 6 to move closer to or away from each other to adjust the spacing to bend them into different angles and shapes. The adjustment operation is relatively convenient, avoiding the need for frequent disassembly and adjustment, and saving time.

[0037] Specifically, refer to Figure 1 , Figure 2 and Figure 4Guide cylinders 4 are fixed around the upper part of the lower die base 1, and reinforcing ribs 8 are installed on the opposite sides of the support member 6, and the lower part of the reinforcing ribs 8 is in contact with the lower die base 1. Through this implementation, the bearing capacity of the support member 6 can be improved under the action of the reinforcing ribs 8, so as to avoid the support member 6 being unable to withstand the force applied during the bending process, so as to reduce the influence of the downward pressure on the driving mechanism, and the reinforcing ribs 8 can also move together with the support member 6 during the movement, and cooperate with the support member 6 to improve the use effect.

[0038] Specifically, refer to Figure 1-2 , guide pillars 3 corresponding to the guide cylinder 4 are installed all around the lower part of the upper die base 2, and a removable upper die 7 is installed at the lower part of the upper die base 2. Through this implementation, the upper die base 2 and the lower die base 1 are installed, and the upper die base 2 can drive the upper die base 2 to move in the vertical direction through the driving member, so that the guide pillars 3 can be accurately connected with the guide cylinder 4 during the downward movement of the upper die base 2, thereby avoiding deviation during the cooperation between the upper die base 2 and the lower die base 1, improving accuracy and stability, and then during the downward movement, pressure can be applied to the workpiece through the upper die 7 and the workpiece can be bent with the cooperation of the rotating member 9, so as to facilitate the disassembly, assembly and replacement of the upper die 7.

[0039] Working principle: When using the utility model, first install the upper die base 2 and the lower die base 1, and place the workpiece to be bent between the limiting parts 10, so that the workpiece to be bent can be limited under the action of the limiting parts 10 to reduce the range of movement of the workpiece and avoid large slippage during the bending operation to affect the bending operation and the bending effect. In addition, the distance between the limiting parts 10 can be adjusted under the action of the adjustment mechanism provided at the lower part. The personnel can rotate the operating part 5 so that the operating part 5 can drive the first bidirectional screw rod 12 to rotate, and the first bidirectional screw rod 12 drives the first threaded sleeve 13 to move in the first slide groove 11. The first threaded sleeve 13 can drive the limiting parts 10 in a group to move away from or close to each other to adjust the distance between them, thereby limiting workpieces of different specifications. The upper die seat 2 is fixedly processed to improve the use effect, and then the power source can drive the upper die seat 2 to move downward. During the downward movement, the upper die seat 2 can apply pressure to the workpiece through the upper die 7 and bend the workpiece with the cooperation of the rotating member 9. The workpiece can change the sliding friction into rolling friction under the action of the rotating member 9 to reduce wear. Subsequently, when adjusting the bending angle of the bent workpiece, the staff can start the motor 16 so that the motor 16 can drive the second bidirectional screw rod 14 to rotate after working. After the second bidirectional screw rod 14 rotates, it will drive the second threaded sleeve 15 to slide in the second slide groove 17, so that the second threaded sleeve 15 can drive the two bearing members 6 to approach or move away from each other to adjust the spacing so as to bend into different angles and shapes. The adjustment operation is relatively convenient, avoiding the need for frequent disassembly and adjustment, and saving time.

[0040] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
