[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example:

[0030] See also Figure 1-8 , a CNC bending machine includes a bending part 1, a conveying limit assembly and a supporting assembly.

[0031] The conveying limit assembly includes a linkage plate 2, an adapter shaft 3, a protective box 4, a baffle 6, an adjustment shaft 7, a rotation drive unit 12, a transmission shaft 13 and a conveying wheel 14. Several adapter shafts 3 are connected to the linkage plate 2, the adapter shaft 3 passes through a side wall of the protective box 4, the adapter shaft 3 is connected to several baffles 6, the adjustment shaft 7 is connected to the linkage plate 2 for transmission, and the rotation of the adjustment shaft 7 can drive the linkage plate 2 to move. The output shaft of the rotation drive unit 12 is connected to the transmission shaft 13, and several conveying wheels 14 are connected to the transmission shaft 13.

[0032] The support assembly includes a guide groove 15 and a support plate 19. The protective box 4, the rotary drive unit 12 and the guide groove 15 are all connected to the support plate 19. Several guide grooves 15 are connected to the support plate 19. The conveying wheel 14 and the guide groove 15 are arranged relative to each other, and the baffle 6 and the guide groove 15 are arranged relative to each other. The cross-section of the guide groove 15 is U-shaped. Preferably, the lower part of the conveying wheel 14 extends into the interior of the guide groove 15, and preferably, the lower part of the baffle 6 extends into the interior of the guide groove 15. The rotary drive unit 12 is a motor, preferably a servo motor with a reducer. The setting of the linkage plate 2 and the adapter shaft 3 increases the position of the support baffle 6, which is conducive to smoothly driving the baffle 6 to move. The bending part 1 is an externally purchased CNC bending equipment, which has the effect of being able to perform bending processing on the bending part, preferably in the form of upper and lower bending, such as a bending machine with model WC67Y. The raw material is transported to the bending part, and the upper and lower molds cooperate to perform bending processing. Through the support plate 1 in the support assembly 9 supports the conveying assembly and the conveyed raw materials, and conveys the sheet metal raw materials to be bent between the conveying wheel 14 and the guide groove 15 and between the baffle 6 and the guide groove 15. The rotating drive unit 12 drives the transmission shaft 13 and the conveying wheel 14 to rotate, thereby driving the raw materials to move step by step, so that the bending part is moved to the CNC bending machine. Multiple raw materials can be set for conveying. Multiple conveying wheels 14 are set on the same transmission shaft 13. By driving multiple raw materials to move at the same time, multiple raw materials can be moved to the bending part at the same time, and multiple parts to be bent can be processed at the same time, thereby improving work efficiency and reducing production costs. The adjustment synchronization effect of driving the raw materials to move at the same time is improved. After rotating the adjusting shaft 7, the adjusting shaft 7 and the linkage plate 2 cooperate to drive the linkage plate 2, the transfer shaft 3 and the baffle 6 to move, so that the baffle 6 is adjusted to different heights, which is suitable for limiting the position of different raw materials and reducing the warping of raw materials.

[0033] Reference Figure 5 and 8 The conveying limit assembly also includes a linkage plate 2 10, the adapter shaft 3 is connected to the linkage plate 2 10, and a plurality of baffles 6 are connected to the linkage plate 2 10. Through the setting of the linkage plate 2 10, the linkage plate 2 10 drives the multiple baffles 6 to move, so that the baffles 6 can limit different raw materials and adapt to adjusting the positions of multiple baffles 6 at the same time.

[0034] Reference Figure 1 and 4 The conveying limit assembly also includes a transmission tube 8. Several transmission tubes 8 are connected to the linkage plate 2. The transmission tube 8 is connected to the adjusting shaft 7. The rotation of the adjusting shaft 7 can drive the transmission tube 8 to move. The adjusting shaft 7 and the transmission tube 8 are connected by a thread. As another application form, the adjusting shaft 7 can be selected as a ball screw, and the transmission tube 8 can be selected as a ball screw nut. Through the setting of the transmission tube 8, it is convenient to process the transmission tube 8. During installation, the transmission tube 8 and the linkage plate 2 can be connected instead of processing threaded holes on the linkage plate 2, which is conducive to assembly and maintenance.

[0035] Reference Figure 1 The conveying limit assembly also includes a handwheel 5, and a plurality of handwheels 5 are connected to the adjusting shaft 7. Through the setting of the handwheel 5, rotating the handwheel 5 drives the adjusting shaft 7 to rotate, thereby facilitating the user's operation.

[0036] Reference Figure 1 The support assembly also includes a limiting nut 16, a positioning screw 17 and a fixing seat 18. A plurality of positioning screws 17 are provided on the fixing seat 18. The positioning screw 17 passes through the fixing seat 18. The positioning screw 17 is connected to a plurality of limiting nuts 16 by threading. The limiting nuts 16 are distributed on both sides of the side wall of the fixing seat 18. The positioning screw 17 is connected to the support plate 19. The limiting nuts 16 pass through the flat plate of the fixing seat 18. The limiting nuts 16 are distributed on both sides of the flat plate of the fixing seat 18. The position of the positioning screw 17 is limited by the limiting nuts 16. The support plate 19 can be adjusted to different height positions, thereby adjusting the position of the supported raw materials, which is conducive to adjusting the conveying position of the raw materials and improving the adaptability to the conveying of the raw materials.

[0037] Reference Figure 5 The conveying limit assembly also includes a guide sleeve 9. Several guide sleeves 9 are connected to the protective box 4. The adapter shaft 3 and the guide sleeve 9 are arranged in a one-to-one correspondence. The adapter shaft 3 passes through the corresponding guide sleeve 9. The guide sleeve 9 is preferably a copper sleeve inlaid with graphite or a linear bearing. The setting of the guide sleeve 9 is conducive to guiding the adapter shaft 3 and reducing the wear between the protective box 4 and the adapter shaft 3.

[0038] Reference Figure 5 and 8 The conveying limiting component also includes rollers 11. Several rollers 11 are rotatably connected to the baffle 6. The baffle 6 is provided with limiting grooves corresponding to the rollers 11. The position of the raw materials is limited by the setting of the rollers 11. When the raw materials move, the raw materials can be pressed by the rolling of the rollers 11, which reduces the wear of the raw materials and is conducive to limiting the position of the raw materials.

[0039] The conveying wheel 14 and the roller 11 are both made of flexible materials, and the conveying wheel 14 and the roller 11 are made of rubber material, preferably polyurethane. As another application form, the conveying wheel 14 can be selected to have a grooved outer wall to drive the raw materials to move gradually. Through the setting of the flexible material, the conveying wheel 14 and the positioning screw 17 can adapt to pressing the raw materials to be processed, thereby improving the positioning effect of the raw materials.

[0040] When in use, the material to be bent is passed through the guide groove 15, and the linkage plate 2 is rotated to make the baffle 6 limit the position of the material, so that the material is in a better conveying position, and the rotary drive part 12 is started. The rotary drive part 12 drives the transmission shaft 13 and the conveying wheel 14 to rotate, and the conveying wheel 14 drives the material to move, so that the material is gradually moved to the bending position.
