DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0034] See also Figure 1-10 The utility model is a guide device for a CNC bending machine, comprising a support plate 1, a bending assembly 2 is fixedly arranged on the top of the support plate 1, the bending assembly 2 comprises a first mold 201 fixed on the top of the support plate 1, a first sliding guide rail 202 is fixed on the top of the support plate 1 on one side of the first mold 201, two sliders 203 are symmetrically slidably fitted on the first sliding guide rail 202, a first mounting guide rail 204 is fixed on the top of the slider 203, a second mold 205 is snap-fitted on the top of the first mounting guide rail 204, and the bottom of the second mold 205 is opened. A slide groove 206 is provided, which is slidably matched with the first mold 201. An adjustment component 3 is provided on one side of the slider 203. The adjustment component 3 includes a motor 301 fixed on an inner side of the support plate 1. The output shaft of the motor 301 is fixedly connected with a transmission gear 302. Two racks 303 are meshed and matched on the side surfaces of the transmission gear 302. A second mounting guide rail 304 is fixed on one side of the two racks 303. A second mounting guide rail 304 is fixedly connected to a slider 203, and a second mounting guide rail 304 is slidably matched with another slider 203.

[0035] The operation process of this embodiment is as follows: according to the length of the processing part of the plate to be processed, the first mold 201 or the second mold 205 is selected for bending processing. Figure 1The figure shows that the first mold 201 is used for bending processing. At this time, the processing part of the plate is located directly above the first mold 201, and the first mold 201 is located between the two second molds 205. Figure 2 The figure shows the bending process using the second mold 205. At this time, the processing part of the plate is located directly above the two second molds 205, and the two second molds 205 are both located above the first mold 201 to prevent the first mold 201 from interfering with the bending action of the second mold 205. The specific appearance features of the first mold 201 and the second mold 205 in the utility model are changed according to the processing requirements.

[0036] When the second mold 205 needs to be used for bending processing, the motor 301 is started to rotate forward, and the output shaft of the motor 301 drives the transmission gear 302 fixedly connected thereto to rotate, and the transmission gear 302 drives the two racks 303 meshing therewith to move in opposite directions, and the two second mounting guide rails 304 respectively drive the two sliders 203 to slide in opposite directions along the first sliding guide rails 202, and the second mold 205 fixed on the slider 203 also moves synchronously therewith. When the two second molds 205 move to the bottom of their respective corresponding processing positions, the motor 301 stops rotating, and the two second molds 205 stop moving, and the subsequent bending processing can be started. When the first mold 201 needs to be used for bending processing, the two sliders 203 are driven by the motor 301 to move toward the two sides of the first mold 201 respectively, so that the two second molds 205 are respectively located on both sides of the first mold 201 to avoid interfering with the bending action of the first mold 201. Specific embodiment 2

[0038] See also Figure 1-10 On the basis of the first specific embodiment, specifically, an inclined groove 207 is provided at the bottom of the slider 203, a square groove 208 penetrating the slider 203 is provided on an inner side of the inclined groove 207, a snap-on assembly 4 is slidably fitted in the slider 203, the snap-on assembly 4 includes a guide inclined plate 401 slidably fitted in the inclined groove 207, a guide groove 402 is provided on one side of the guide inclined plate 401, an inclined plate 403 is slidably fitted in the guide groove 402, a card plate 404 slidably fitted with the square groove 208 is fixed on the side of the inclined plate 403 away from the guide inclined plate 401, a second dovetail groove 209 matching the first mounting guide rail 204 is provided at the bottom of the second mold 205, and a limiting groove 212 slidably fitted with the card plate 404 is provided at the top of the second dovetail groove 209.

[0039] The operation process of this embodiment is as follows: the second mold 205 often needs to be replaced according to the structure and molding requirements of the processed plate. When the second mold 205 is installed on the slider 203 for the first time, the inclined plate 403 fixed on one side of the clamping plate 404 is first inserted into the guide groove 402, and the clamping plate 404 and the guide inclined plate 401 are respectively inserted into the square slide groove 208 and the inclined groove 207 from the bottom of the slider 203, and then the slider 203 is installed on the first sliding guide rail 202, and the second mold 205 is installed on the first installation guide rail 204 through the second dovetail groove 209, and the inclined plate 403 is pushed to one side so that the inclined plate 403 is in the first installation guide rail 204. The guide groove 402 slides, so that the card plate 404 moves upward, and one end of it is inserted into the limit groove 212, so that the second mold 205 can be completely fixed on the first mounting guide rail 204. When removing the second mold 205, the guide inclined plate 401 is pushed in the opposite direction to make the card plate 404 move downward, and one end of it is separated from the limit groove 212. At this time, the second mold 205 can be slid to both sides, so that the second mold 205 is separated from the first mounting guide rail 204 and then completely disassembled. This replaces the fixing of the second mold 205 on the first mounting guide rail 204 by bolts, thereby avoiding the bending effect of the second mold 205 being affected by loose bolts. Specific embodiment three

[0041] See also Figure 1-10 On the basis of the first and second specific embodiments, specifically, an L-shaped slide groove 210 is provided on one side of the slider 203, two first slots 211 are provided on the bottom of the L-shaped slide groove 210, an L-shaped slide plate 405 is slidably matched in the L-shaped slide groove 210, a limiting plate 406 is fixed at the bottom of the L-shaped slide plate 405, a second slot 407 is provided on one end of the guide inclined plate 401, two symmetrical fixed plates 101 are fixed on the top of the support plate 1, one side of the two fixed plates 101 are both threadedly connected with a hydraulic buffer 102, first dovetail grooves 103 are provided on the opposite sides of the support plate 1, second sliding guide rails 104 are slidably matched inside the two first dovetail grooves 103, and a hydraulic cylinder 5 is fixed at the bottom of the support plate 1.

[0042] The operation process of this embodiment is as follows: when the guide inclined plate 401 is pushed to control the card plate 404 to insert into or disengage from the limiting groove 212, it is necessary to consider that when the device is working, the movement of the slider 203 will drive the guide inclined plate 401, thereby affecting the fixation of the second mold 205. Depending on which side the guide inclined plate 401 moves to the slider 203, the card plate 404 will be driven to move downward, thereby opening an L-shaped slide groove 210 and a first groove 211 on the side of the slider 203. When the card plate 404 is inserted into the limiting groove 212 and cannot move upward, the L-shaped slide plate 405 can be inserted from one end of the L-shaped slide groove 210, and the L-shaped slide plate 405 can slide to one side in the L-shaped slide groove 210 to the bottom, and then the L-shaped slide plate 405 can be moved downward, so that one end of the L-shaped slide plate 405 is inserted into the first groove 211 close to the guide inclined plate 401, and the other end of the L-shaped slide plate 405 is inserted into the first groove 211 close to the guide inclined plate 401. The first end of the L-shaped slide 405 is inserted into the second slot 407, and then the limit plate 406 is inserted into the L-shaped slide 210, so that the L-shaped slide 405 limits the guide inclined plate 401 from moving toward the side of the slider 203, thereby driving the card plate 404 to move downward, so as to stably fix the second mold 205 on the first mounting guide rail 204. Therefore, when disassembling the second mold 205, it is necessary to first slide the L-shaped slide 405 upward and move the L-shaped slide 405 to the other side until one end of the L-shaped slide 405 moves to the top of the first slot 211 away from the guide inclined plate 401. At this time, move the L-shaped slide 405 downward so that one end of the L-shaped slide 405 is inserted into the first slot 211, and the other end of the L-shaped slide 405 is also completely away from the second slot 407, so that the guide inclined plate 401 can be pushed to disassemble and install the second mold 205.

[0043] When the motor 301 reverses and drives the two sliders 203 to slide toward the two sides of the first mold 201, two hydraulic buffers 102 are provided to prevent the motor 301 from driving the two sliders 203 to slide out of the first sliding guide rail 202. When the first mold 201 or the second mold 205 is located directly below the sheet processing part, the support plate 1 is driven by the hydraulic cylinder 5 to move upward along the two second sliding guide rails 104. At the same time, the support plate 1 drives the first mold 201 or the second mold 205 to move upward, so as to bend the sheet processing part fixed on the clamping table. Here, the two second sliding guide rails 104 are fixed on the CNC bending machine frame (the CNC bending machine frame is a prior art, not drawn in the figure, and will not be elaborated here).
