Through stamping, whether it is the demand for equipment, the development cycle of molds, the versatility of molds, or the cost of molds, the development progress of products is restricted. Therefore, it is imperative to adopt sheet metal technology.

[0003] After searching, a Chinese utility model patent disclosed a CNC bending machine positioning tool with publication number CN205042951U. It includes a bending machine rear baffle and a positioning block arranged on the guide rail of the bending machine rear positioning system; the bending machine rear baffle is composed of a fixing seat, a positioning plate, front and rear advance and retreat bolts and a locking bolt.

[0004] In the above patent documents, the position limitation of sheet metal parts is mainly achieved through two sets of fixing seats, and the fixing method at this time is to use bolts to squeeze the guide rails to achieve the position limitation by vertical stress.

[0026] Further, the driving assembly 5 includes a rack plate 51 fixedly mounted on the left end surface of the center column 3, and a driving gear 52 rotatably mounted on the front and rear sides of the left portion of the upper end surface of the device box 2, and the driving gear 52 is meshed and connected with the rack plate 51;

[0027] The inner cavity of the device box 2 is fixedly mounted with a driving motor 53 through a frame, the output shaft end of the driving motor 53 is fixedly connected to the driving gear 52 located at the front side, and rubber pads are fixedly mounted around the lower end surface of the mounting base plate 1.

[0028] Furthermore, the limiting assembly 8 includes a guide column 81 slidably mounted in the inner cavity of the guide sleeve 6, and a connecting rod 82 rotatably mounted on the right end of the guide column 81, and an ear column 83 is rotatably mounted on the right end of the guide column 81, and a limiting plate 84 is rotatably mounted in the middle of the inner cavity of the ear column 83, and the left end of the limiting plate 84 is fixedly connected to the right end of the ear column 83 through a high-strength spring 85;

[0029] One end of the connecting rod 82 away from the guide column 81 is rotatably installed in the inner cavity of the connecting seat 4. A limiting groove 811 is opened on the left side wall of the guide column 81. A limiting pin 812 is threadedly installed in the inner cavity of the limiting groove 811. Several groups of limiting grooves 811 are set on the side wall of the guide column 81.

[0030] It should be noted that, by installing the guide column 81 in the limiting groove 811 at different positions, the sliding distance of the guide column 81 in the inner cavity of the guide sleeve 6 can be changed, so as to change the range of the limiting plate 84 on the sheet metal part.

[0031] It should be noted that by starting the driving motor 53, the driving gear 52 on the front side is rotated. At this time, under the limiting action of the driving gears 52 on the front and rear sides, the driving gear 52 will drive the rack plate 51 to move the center column 3 to the right side of the installation base plate 1. Since the connecting seat 4 is fixedly connected to the center column 3, the connecting seat 4 will also be displaced to the right side at this time, and pull the front and rear connecting rods 82 to move to the right side. They are fixedly connected to the guide column 81 through the connecting rod 82. At this time, the guide column 81 will also move to the right side under the restraining action of the guide sleeve 6, so that the ear columns 83 rotatably installed on the guide columns 81 on the front and rear sides will be close to each other. Under the elastic force of the high-strength spring 85, the limiting plate 84 will always be flush with the ear columns 83. As the front and rear ear columns 83 approach, the distance between the front and rear limiting plates 84 will also change to meet the area of ​​the sheet metal that the workers need to bend. This adjustment method replaces the traditional method of fixing with bolts, which is convenient and fast, and can be used for a long time.

[0032] Further, the adjustment assembly 9 includes a fixed sleeve 91 rotatably mounted on the middle part of the right side of the upper end surface of the mounting base plate 1, a movable column 92 is threadedly mounted on the inner cavity of the fixed sleeve 91, a transmission worm gear 93 is fixedly mounted on the side wall of the fixed sleeve 91, a vertical plate 94 is fixedly mounted on the side of the upper end surface of the mounting base plate 1 close to the fixed sleeve 91, and a transmission worm 95 is rotatably mounted in the inner cavity of the vertical plate 94;

[0033] The transmission worm 95 is meshed and connected with the transmission worm wheel 93. The right side of the upper end surface of the mounting base plate 1 is fixedly mounted with an adjustment motor 96 through a frame. The output shaft end of the adjustment motor 96 is fixedly connected with the transmission worm wheel 93. The movable column 92 is fixedly mounted on the lower end surface of the support platform 7.

[0034] The upper end surface of the mounting base plate 1 is located below the four corners of the support platform 7 and fixedly mounted with a limiting sleeve 11 . The inner cavity of the limiting sleeve 11 is slidably mounted with a limiting rod 12 . The limiting rod 12 is fixedly mounted on the lower end surface of the support platform 7 .

[0035] It should be noted that by starting the adjusting motor 96 to rotate the transmission worm 95, since the transmission worm 95 is meshingly connected with the transmission worm wheel 93, the transmission worm wheel 93 will drive the fixed sleeve 91 to rotate through the threaded connection between the fixed sleeve 91 and the movable column 92. At this time, under the limiting action of the limiting sleeves 11 and the limiting rods 12 at the four corners of the support platform 7, the height of the support platform 7 will change.

[0036] Working principle:

[0037] Before bending a sheet metal part:

[0038] The worker can start the driving motor 53 to rotate the driving gear 52 on the front side. At this time, under the limiting action of the driving gears 52 on the front and rear sides, the driving gear 52 will drive the rack plate 51 to move the center column 3 to the right side of the installation base plate 1. Since the connecting seat 4 is fixedly connected to the center column 3, the connecting seat 4 will also move to the right side at this time, and pull the front and rear connecting rods 82 to move to the right side. They are fixedly connected to the guide column 81 through the connecting rod 82. At this time, the guide column 81 will also move to the right side under the restraining action of the guide sleeve 6, so that the ear columns 83 rotatably installed on the guide columns 81 on the front and rear sides will be close to each other. Under the elastic force of the high-strength spring 85, the limiting plate 84 will always be flush with the ear columns 83. As the ear columns 83 on the front and rear sides approach, the spacing between the limiting plates 84 on the front and rear sides will also change to meet the area of ​​the sheet metal that the worker needs to bend. This adjustment method replaces the traditional method of fixing with bolts, which is convenient and fast, and can be used for a long time.

[0039] The worker can also start the adjustment motor 96 to rotate the transmission worm 95. Since the transmission worm 95 is meshed and connected with the transmission worm wheel 93, the transmission worm wheel 93 will drive the fixed sleeve 91 to rotate and be threadedly connected with the movable column 92 through the fixed sleeve 91. At this time, under the limiting action of the limiting sleeves 11 and the limiting rods 12 at the four corners of the support platform 7, the height of the support platform 7 will change, so as to be suitable for workers to bend sheet metal parts with different groove depths, thereby improving the practicality of the entire device;

[0040] When bending the sheet metal part: the worker uses a mold to press the sheet metal part placed on the limiting plate 84 downward, so that the sheet metal part is deformed to form a groove with a depth such as the spacing between the limiting plate 84 and the support platform 7.

[0041] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
