[0026] See also Figure 1-5 , a die strip for CNC bending, comprising:

[0027] The mold strip body 1 has a limit groove at the upper end of the back side of the mold strip body 1;

[0028] A support seat 3, the support seat 3 is clamped on the upper end of the mold strip body 1;

[0029] The mold strip body 1 is composed of a plurality of sub-modules 2, one side of the sub-module 2 is provided with a slot 201, and the side of the sub-module 2 away from the slot 201 is fixedly provided with a plug 202 that cooperates with the slot 201, and the upper end and both sides of the support seat 3 are provided with a limited clamping assembly 5;

[0030] The position limiting clamping assembly 5 includes a slide plate 501 , which is slidably disposed on the upper end of the support seat 3 .

[0031] Among them; a guide hole 203 connected to the inside of the slot 201 is opened on the supporting surface of the sub-module 2, and a T-shaped plug block 4 is set on the sub-module 2 through the guide hole 203. A positioning hole 204 that cooperates with the T-shaped plug block 4 is opened in the center of the plug 202. By inserting the plug 202 of one sub-module 2 into the slot 201 of another sub-module 2, and then passing the vertical rod of the T-shaped plug block 4 through the guide hole 203 and snapping it into the positioning hole 204, the two sub-modules 2 are effectively spliced ​​and fixed, and the number of sub-modules 2 to be used can be determined according to the length of the sheet metal that needs to be bent. When a sub-module 2 is damaged, it can be replaced without affecting the use of other sub-modules 2, avoiding waste of resources.

[0032] Among them; the limiting clamping assembly 5 also includes a connecting rod 504, a limiting column 505 and a threaded rod 506. A sliding hole is opened on the support seat 3. The slide plate 501 passes through the sliding hole and is slidably connected to the inner wall of the sliding hole. By opening a sliding hole on the support seat 3, it is convenient to install the slide plate 501, and the slide plate 501 can be slidable to adjust the front and rear positions.

[0033] Among them, there are several limit columns 505, and the limit columns 505 are equidistantly arranged on the back of the connecting rod 504. The side wall of the support seat 3 is provided with a through hole for the front end of the limit column 505 to pass through. The upper end of the front side of the sub-module 2 is provided with a limit hole 205 that cooperates with the limit column 505. The connecting rod 504 is provided to facilitate the installation of the limit column 505, and by controlling the movement of the connecting rod 504, the multiple limit columns 505 thereon can be controlled to move synchronously. When the front end of the limit column 505 passes through the through hole and is inserted into the limit hole 205, it can effectively limit the support seat 3.

[0034] Among them, a strip groove 503 is opened at one end of the slide plate 501 close to the connecting rod 504, and the upper end of the threaded rod 506 passes through the strip groove 503 and is threadedly connected with a fastening nut 507, and a limiting clamping plate 502 that cooperates with the limiting groove is fixedly set at the end of the slide plate 501 away from the strip groove 503.

The operation is simple and convenient for later disassembly and replacement, saving time and effort.

[0035] The working principle is that the plug 202 of one sub-module 2 is inserted into the slot 201 of another sub-module 2, and then the vertical rod of the T-shaped plug block 4 is passed through the guide hole 203 and inserted into the positioning hole 204, so as to achieve effective splicing and fixation of the two sub-modules 2, and the number of sub-modules 2 to be used can be determined according to the length of the sheet metal to be bent. When a sub-module 2 is damaged, it can be replaced without affecting the use of other sub-modules 2, avoiding waste of resources.

[0036] Furthermore, the combined mold strip body 1 is clamped with the support seat 3, and by controlling the movement of the connecting rod 504, the multiple limit columns 505 thereon can be controlled to move synchronously. When the front end of the limit column 505 passes through the perforation and is clamped into the limit hole 205, it can effectively limit the support seat 3, and then pull the slide plate 501 to move to the side of the connecting rod 504. The slide plate 501 pulls the limit clamping plate 502 to clamp with the limit groove, which can further play a limiting and supporting role for the support seat 3. Finally, the slide plate 501 is tightened by rotating the fastening nut 507 to achieve effective installation and fixation of the support seat 3. The operation is simple and convenient for later disassembly and replacement, saving time and effort.
