[0018] See also Figure 1 and 2 The utility model provides a technical solution: a bending die of a bending machine, comprising a bottom plate 1 and two opposite side plate assemblies, the side plate assembly moves along the length direction of the bottom plate 1, the side plate assembly comprises a base 2, a top plate 3 and a plurality of webs 4, the base 2 slides along the top of the bottom plate 1, the top of the base 2 and the top of the web 4 are respectively provided with a plurality of grooves and protrusions, the bottom of the web 4 and the bottom of the top plate 3 are respectively provided with card strips and card embedding grooves engaged with the grooves and the protrusions, the web 4 is detachably mounted on the top of the base 2, and the top plate 3 is detachably mounted on the top of the uppermost web 4 or the top of the base 2.

[0019] The two sets of opposite side panel assemblies at both ends move along the length direction of the bottom plate 1, respectively moving outward or inward to change the distance between the two sets of side panel assemblies, thereby adjusting the length of the bending part to meet the bending requirements of workpieces with different bending lengths.

[0020] There are multiple webs 4, and the heights of the multiple webs 4 can be the same or can vary in order. The side panel assembly changes the number of placed webs 4 according to different depth requirements, thereby changing the height of the side panel assembly on one side, and splicing them to form a side panel assembly with a height that meets the requirements.

[0021] In this embodiment, the material is placed on the side panel assembly, and the side panel assembly is adjusted according to the required height and length of the material. The minimum is to directly install the top panel 3 on the top of the base 2, and engage the clamping strip and the clamping groove at the bottom end of the top panel 3 with the groove and the protrusion at the top end of the base 2. When the height is increased, the belly panel 4 is added to engage the clamping strip and the clamping groove at the bottom end of the belly panel 4 with the groove and the protrusion at the top end of the base 2. If the height is not enough, continue to add belly panels 4, and engage the clamping strip and the clamping groove at the bottom end of the newly added belly panel 4 with the groove and the protrusion at the top end of the originally added belly panel 4. Finally, the top panel 3 is installed on the top end of the belly panel 4 to realize the assembly of the side panel assembly on one side.

[0022] The included angles between the bottom plate 1 and the two side plate components are both 90°. In this state, it is suitable for direct bending to bend the workpiece into a right-angled U-shaped structure.

[0023] Second embodiment

[0024] Please refer to Figure 1 and 3, and also includes multiple inclined plates 6, the top of the inclined plate 6 extends laterally outward to form a horizontal mounting plate, the top of the top plate 3 is provided with multiple slots, and the bottom end of the inclined plate 6 is provided with a block that engages with the top of the top plate 3. The upper end of the inclined plate 6 is detachably mounted on the top of the top plate 3 and the bottom end is in contact with the upper surface of the bottom plate 1.

[0025] Some workpieces need to be bent at a specific bending angle rather than a right-angle bend, so the bending mold in the first embodiment cannot meet the requirements of bevel bending. Therefore, based on the first embodiment, a detachable inclined plate 6 is added to meet the processing requirements of bevel bending.

[0026] There are multiple groups of inclined plates 6, and the inclination angles of the multiple groups of inclined plates 6 are different, but the bottom edges are all flat, and each inclination angle is equipped with multiple inclined plates 6 of different lengths to meet the bending requirements of different angles and different depths.

[0027] In this embodiment, the block at the bottom end of the inclined plate 6 is engaged with the slot at the top end of the top plate 3 , and the bottom end of the inclined plate 6 abuts against the upper surface of the bottom plate 1 without leaving any gap.

[0028] The clamping blocks at the bottom of the inclined plates 6 provided with multiple groups can all be engaged with the clamping grooves at the top of the top plate 3 .

[0029] Furthermore, the inclined plate 6 is a hollow triangular frame structure, and a plurality of fixing rods 7 are arranged in the inner cavity of the triangular frame.

[0030] In this embodiment, a plurality of fixing rods 7 are fixedly connected to the inner cavity of the triangular frame, so that the hollow triangular frame structure is more stable and will not be deformed when the inclined plate 6 is subjected to a force from top to bottom.

[0031] Furthermore, both sides of the base 2 extend downward to form a guide block 12 that slides along the side of the bottom plate 1. A bidirectional threaded rod 8 is rotatably provided on one side of the bottom plate 1. Both ends of the surface of the bidirectional threaded rod 8 are respectively threadedly connected with threaded sleeves 11, and each threaded sleeve 11 is fixedly connected to a guide block 12 on one side.

[0032] In this embodiment, the bidirectional threaded rod 8 is rotated to drive the side panel assemblies on both sides to move outward or inward respectively to change the distance between the two groups of side panel assemblies. The surface of the bidirectional threaded rod 8 is threadedly connected with a threaded sleeve 11 so that the bidirectional threaded rod 8 can rotate in the bottom plate. The threaded sleeve 11 is fixedly connected to the guide block 12 to ensure that the two groups of side panel assemblies can move accurately.

[0033] Furthermore, a slide rail 5 is provided on the other side of the base plate 1 along the length direction, and the guide block on the other side is slidably connected to the slide rail 5 .

[0034] In this embodiment, a bidirectional threaded rod 8 is provided on one side of the bottom plate 1 to control the side plate assembly, and a slide rail 5 is provided on the other side to facilitate more accurate movement of the side plate assembly outward or inward.

[0035] Furthermore, one end of the bidirectional threaded rod 8 is rotatably connected to the outside of the base plate 1 , and the outer end of the bidirectional threaded rod 8 is fixedly connected to the turntable 9 , and the outer end of the turntable 9 is fixedly connected to the handle 10 .

[0036] In this embodiment, a turntable 9 is provided at one end of the bidirectional threaded rod 8 , and a handle 10 is provided on the turntable 9 to facilitate the rotation of the bidirectional threaded rod 8 .

[0037] The slot at the top of the top plate 3 is at the outer edge. When a right-angle bend is performed, the slot at the top of the top plate 3 will be exposed. At this time, the horizontal part of the upper die will not extend to the slot position, avoiding annular marks on the material surface at the slot.

[0038] The working principle and use process of the utility model: After the utility model is installed, the mold is adjusted according to the different specifications of the material. First, the web 4 is added to the base 2, and the embedding groove and the card strip at the bottom of the web 4 are engaged with the groove and the protrusion at the top of the base 2, and then the embedding groove and the card strip at the bottom of the top plate 3 are engaged with the groove and the protrusion at the top of the web 4, and then the handle 10 is rotated to drive the turntable 9 to rotate, so that the two-way threaded rod 8 drives the side panel assembly to slide, and it can be bent after the adjustment is completed. Then, if the material needs to be bent at an angle, you can install the inclined plate 6 on the top plate 3, so that the card block at the bottom of the inclined plate 6 is engaged with the card groove opened in the top plate 3, and then adjust the position of the side panel assembly, and then bend it. If no angle bending is required, the inclined plate 6 does not need to be installed, and then the mold is adjusted according to the different materials to achieve the bending of different materials.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
