DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4, the present utility model provides a technical solution: a disassembly and assembly structure of a bending machine that is convenient for disassembly and assembly, including a machine tool plate 1, on the top of the machine tool plate 1 slides a mold main body 2, on the top of the machine tool plate 1 is installed a disassembly and assembly component 300 for positioning the mold main body 2, and on the top of the machine tool plate 1 is installed a bending machine component 400 for using the mold main body 2 to perform bending work; through the coordinated use of the mold main body 2, the disassembly and assembly component 300 on the top of the machine tool plate 1, and the bending machine component 400 on the outside, the rapid disassembly and assembly of the mold can be conveniently and simply achieved, and there is no need to lift the mold again when disassembling and assembling the mold, so that the mold can be smoothly moved and limited in position, and at the same time, the number of structures required for disassembly is reduced, so that the actual cost can be controlled, which is conducive to extensive promotion, thereby effectively improving the practicability of the disassembly and assembly structure of the bending machine.

[0028] In this embodiment, the disassembly and assembly component 300 is a structure for facilitating the disassembly, assembly and replacement of the mold.

[0029] As Figure 2 、 Figure 3 and Figure 4 shown, the disassembly and assembly component 300 includes a positioning plate 301 fixed to the top of the machine tool plate 1, two limit blocks 302 fixed to the top of the machine tool plate 1, a sliding hole 303 opened on the left side of the limit block 302, two connecting plates 304 respectively fixed to the left and right sides of the mold main body 2, a bolt 305 penetrating through the front of the connecting plate 304, a nut 306 threadedly connected to the outside of the bolt 305, two first limiting blocks 307 fixed to the front of the positioning plate 301, four second limiting blocks 308 respectively fixed to the top and bottom of the two first limiting blocks 307, two first limiting slots 309 opened on the back of the mold main body 2 for the corresponding first limiting blocks 307 to be inserted, and four second limiting slots 310 opened on the back of the mold main body 2 for the corresponding second limiting blocks 308 to be inserted.

[0030] It should be noted that the two limit blocks 302 are symmetrically distributed left and right, the back of the limit block 302 is fixedly connected to the front of the positioning plate 301, the side of the limit block 302 away from the positioning plate 301 on the outside is inclined, and the inclination direction is the side where the two limit blocks 302 are opposite to each other. Among them, the transition connection between the inclined part and the non-inclined part is arc-shaped, which is convenient for the mold main body 2 to slide, so that a space with an open front end can be formed between the opposite sides of the two limit blocks 302, which is convenient for the mold main body 2 to enter the inside of this space from between the two limit blocks 302, and then the mold main body 2 can be limited and positioned through the limiting effect between the limit blocks 302.

[0031] In addition, the two connecting plates 304 are respectively slidably connected to the inner sides of the two sliding holes 303, and the opposite sides of the two connecting plates 304 extend to the opposite sides of the two limiting blocks 302 respectively, enabling the connecting plates 304 to move normally. When the front ends of the limiting blocks 302 are inclined, it is convenient for the connecting plates 304 to enter the inner sides of the sliding holes 303 from the outside and also to move out of the inner sides of the sliding holes 303 to the outside.

[0032] Furthermore, the back surface of the connecting plate 304 can be attached to the front surface of the positioning plate 301. The length of the bolt 305 is greater than the sum of the thicknesses of the positioning plate 301 and the connecting plate 304. The end of the bolt 305 penetrates the front surface of the positioning plate 301, and the front surface of the nut 306 is attached to the back surface of the positioning plate 301, enabling the bolt 305 to pass through between the inner sides of the positioning plate 301 and the corresponding connecting plate 304 and fixing the two with the nut 306.

[0033] Meanwhile, a cross shape is formed between the outer sides of the two corresponding second limiting blocks 308 and the first limiting block 307. The two first limiting blocks 307 are symmetrically distributed left and right. The back surface of the second limiting block 308 is fixedly connected to the front surface of the positioning plate 301. The inside of the first limiting groove 309 is communicated with the inside of the two corresponding second limiting grooves 310, enabling the first limiting block 307 and the second limiting block 308 to be respectively inserted into the inner sides of the first limiting groove 309 and the second limiting groove 310 normally, so that the first limiting groove 309 and the second limiting groove 310 can provide a limiting function.

[0034] In this embodiment, the bending machine assembly 400 is a structure for performing workpiece bending processing.

[0035] As Figure 1 shown, the bending machine assembly 400 includes four support legs 401 fixed to the bottom of the machine tool plate 1 and evenly distributed, four auxiliary support rods 402 fixed between the opposite sides of the two front support legs 401 and between the opposite sides of the two back support legs 401, a fixing plate 403 fixed to the top of the machine tool plate 1, and a bending device main body 404 fixedly installed on the front surface of the fixing plate 403.

[0036] It should be noted that the two front and two back auxiliary support rods 402 are both distributed in an X shape, enabling the auxiliary support rods 402 to provide an additional support and stability function for the support legs 401. The bending device main body 404 is located above the mold main body 2, enabling the bending device main body 404 to cooperate with the mold main body 2 for bending work.

[0037] In addition, the bending device main body 404 presses the upper die downward through hydraulic or electric drive, so as to bend the workpiece to be processed under the cooperation of the upper die and the die main body 2. Since the bending device main body 404 is an existing publicly disclosed technology, it will not be elaborated here.

[0038] The working principle of the above embodiment is as follows:

[0039] When it is necessary to disassemble and assemble the die main body 2, loosen the nut 306 and remove the bolt 305, so that the connecting plate 304 is no longer connected to the positioning plate 301. Then, the die main body 2 can be slid to the front side to move it away from the machine tool plate 1. Move the replaced die main body 2 to the top of the machine tool plate 1 and push the die main body 2 to move toward the side close to the positioning plate 301. Under the limiting action of the two limiting blocks 302 on both sides, the die main body 2 can be smoothly moved to the front of the positioning plate 301, so that the first limiting block 307 is inserted into the inner side of the corresponding first limiting groove 309, and the second limiting block 308 is inserted into the inner side of the corresponding second limiting groove 310. Make the back of the die main body 2 abut against the front of the positioning plate 301. During the moving process, the connecting plate 304 slides inside the corresponding sliding hole 303, so that the backs of the two connecting plates 304 also fit against the front of the positioning plate 301. Pass the bolt 305 between the inner sides of the connecting plate 304 and the positioning plate 301 and tighten the nut 306, then the disassembly, assembly and replacement work of the die main body 2 can be completed. Start the bending device main body 404 to start the bending processing work of the workpiece.

[0040] Compared with the prior art, the disassembly and assembly structure of the bending machine with convenient disassembly and assembly can conveniently and simply realize the rapid disassembly and assembly of the die through the cooperation of the die main body 2 on the top of the machine tool plate 1, the disassembly and assembly component 300 and the bending machine component 400 on the outside. And when disassembling and assembling the die, there is no need to lift the die again, so that the die can be smoothly moved and limited and positioned. At the same time, the number of structures required for disassembly is also reduced, so that the actual cost can be controlled, which is conducive to wide promotion. Thus, the practicability of the disassembly and assembly structure of the bending machine is effectively improved, and the problem that the existing rapid die change device of the bending machine tool is more convenient in operation but requires a large number of structures and also needs to lift the die for movement is solved.

The provision of the power supply belongs to the common knowledge in the field. The main controller can be a conventional known device such as a computer for control, which can be realized by simple programming of those skilled in the art.
