[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Reference Figures 1 to 3 As shown, the utility model provides a bending machine mold structure, including: a base 1, a support 2, and a support platform 3.

[0023] The base is in the shape of a long strip. The base is arranged along the length direction of the working table of the bending machine. The base 1 is detachably mounted on the working table of the bending machine. Preferably, the base is mounted on the working table of the bending machine by bolts.

[0024] In this embodiment, two opposite sides of the base 1 are respectively provided with sliding grooves arranged along the width direction of the base 1 .

[0025] There are two supports 2. The two supports are arranged opposite to each other. Each support is arranged along the length direction of the base. The two supports are arranged on opposite sides of the base respectively. A slider 21 is formed at the bottom of the support 2. The slider 21 is slidably arranged in the slide groove. Limiting grooves 20 are formed on opposite sides of the two supports 2 respectively. The two supports 2 are provided with threaded through holes. A translation screw 22 is screwed into the threaded through holes of the two supports 2. The thread directions of the threaded through holes of the two supports 2 are opposite.

[0026] In this embodiment, the slide groove is a dovetail groove, and the shape of the cross section of the corresponding slider is adapted to the properties of the cross section of the slide groove.

[0027] The support platform 3 is movably arranged between the two supports 2. The opposite sides of the support platform 3 extend into the limiting grooves 20 of the two supports 2 respectively. A driving mechanism 31 for lifting the support platform 3 is installed on the base 1. A shaping groove 30 with adjustable shape and size is formed between the support platform 3 and the two supports 2. The shaping groove 30 is arranged just below the upper die of the bending machine.

[0028] In this embodiment, the groove depth and the width of the notch of the shaping groove can be changed. Specifically, the adjustment of the groove depth of the shaping groove is achieved by driving the mechanism to raise and lower the support platform. When the support platform rises, the groove depth of the shaping groove becomes shallower, and vice versa.

[0029] The width of the notch of the shaping groove is realized by the translation screw. When the translation screw rotates forward and the two supports approach each other, the width of the notch of the shaping groove becomes smaller, and vice versa.

[0030] When bending the workpiece, the depth and width of the shaping groove are adjusted by the driving mechanism and the translation screw respectively based on the bending angle and the width of the workpiece. After the upper die of the bending machine is pressed down, the workpiece is pressed into the shaping groove for bending and shaping.

[0031] As a preferred embodiment, rollers 23 are rotatably mounted on the tops of the two supports 2. The rollers 23 are arranged at the corners of the tops of the supports 2. The rollers are arranged along the length direction of the base.

[0032] In this embodiment, the end of the translation screw 22 extends to the outside of the support 2 and is connected to a hand wheel 24. When the width of the shaping groove is adjusted, the translation screw is driven to rotate by the rotation of the hand wheel.

[0033] In this embodiment, the length of the limiting groove 20 is adapted to the length of the support 3. The support can move in the vertical direction (or the groove wall of the limiting groove can move up and down), and can also move in the axial direction of the translation screw.

[0034] As a preferred embodiment, the driving mechanism 31 includes: a lifting screw 311 and a motor (not shown in the drawings).

[0035] Specifically, there are multiple lifting screws. Multiple lifting screws 311 are arranged along the length direction of the support platform 3. The base 1 is provided with a threaded hole. The lifting screw 311 is screwed into the threaded hole. The upper end of the lifting screw 311 is rotatably connected to the bottom of the support platform 3.

[0036] The motor is mounted on the base 1 and is connected to a plurality of lifting screws 311 in a transmission manner.

[0037] In this embodiment, a mounting groove 10 is formed at the bottom of the base 1. The lower end of the lifting screw 311 extends into the mounting groove 10. The motor is installed in the mounting groove 10.

[0038] The lower end of the lifting screw is coaxially connected with a synchronous pulley 312. The synchronous pulleys 312 at the lower ends of the plurality of lifting screws are meshed with a synchronous belt 313.

[0039] The output shaft of the motor is drivingly connected to a lifting screw.

[0040] The mold structure of the bending machine of the utility model can adjust the groove depth of the shaping groove by raising and lowering the support platform through the driving mechanism. When the support platform rises, the groove depth of the shaping groove becomes shallower. On the other hand, the width of the notch of the shaping groove is achieved by the rotation of the translation screw. When the translation screw rotates forward and the two supports approach each other, the width of the notch of the shaping groove becomes smaller. The mold structure of the bending machine of the utility model can quickly adjust the size and shape of the shaping groove through the driving mechanism and the translation screw, forming shaping grooves of different sizes and shapes to adapt to the bending of workpieces of different models, thereby improving the workpiece processing efficiency and reducing the time investment in mold replacement.

[0041] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
