[0025] As Figures 1 to 3 The present application provides a production line for producing stamping parts. The production line of the present application includes a shearing device 10, a first conveying device 21, a leveling device 30, a second conveying device 22, a third conveying device 23, a diverging device, a first cutting device 50, and a second cutting device 60. The input end of the first conveying device 21 is connected downstream of the discharge end of the shearing device 10. The feeding end of the leveling device 30 is connected downstream of the output end of the first conveying device 21. The input end of the second conveying device 22 is connected downstream of the discharge end of the leveling device 30. The input end of the third conveying device 23 corresponds to the middle part of the second conveying device 22, and the third conveying device 23 is arranged intersecting the second conveying device 22. The diverging device is used to transport the strip 41 on the second conveying device 22 to the third conveying device 23. The feeding end of the first cutting device 50 is arranged downstream of the output end of the second conveying device 22. The feeding end of the second cutting device 60 is arranged downstream of the output end of the third conveying device 23.

[0026] The shearing device 10 can cut the large plate material (i.e., the plate material 42) into a long strip material 41, the strip material 41 is conveyed to the flattening device 30 under the action of the first conveying device 21, and the strip material 41 is conveyed to the subsequent cutting process after being flattened and cut into a block structure. The shunt device is arranged between the flattening device 30 and the cutting process, and the strip material 41 processed by the shearing device 10 and the flattening device 30 is shunted, so that the strip material is divided into two paths and conveyed to the first cutting device 50 and the second cutting device 60. That is, by arranging the shunt device and adding one cutting device, the efficiency difference between the shearing device 10 and one cutting device is made up, so that the shearing device 10 can operate at full capacity or at a higher load, avoiding capacity waste, ensuring production efficiency and balanced production of the whole production line. Therefore, the technical scheme of the embodiment can effectively solve the problem of capacity waste caused by the lower efficiency of the cutting process than the shearing process in the related art.

[0027] It should be noted that the "middle part of the second conveying device 22" refers to the position of the second conveying device 22 other than the end part, for example, the middle 3 / 4 or even 4 / 5 length part of the second conveying device 22 can be considered as the middle part of the second conveying device 22.

[0028] Specifically, in the embodiment, the first to third conveying devices are all transmission roller structures, which connect each process to avoid manual handling between processes, realize automatic production, and further improve production efficiency. The flattening device 30 includes an upper roller group and a lower roller group, and the strip material 41 is subjected to extrusion between the upper and lower roller groups when passing through the upper and lower roller groups, thereby achieving flattening. The transmission roller of the first conveying device 21 is arranged flush with the lower roller group, so that the strip material 41 conveyed by the first conveying device 21 can be directly conveyed between the upper and lower roller groups.

[0029] As shown in Figures 1 to 3 The shearing device 10 includes a shearing machine 11, a feeding device 12, a first material rack 13, and a second material rack 14, the first material rack 13 and the second material rack 14 are used to carry the plate material 42, and the feeding device 12 is used to convey the plate material 42 on the first material rack 13 and the second material rack 14 to the shearing machine 11. The first and second material racks are arranged, different specifications (i.e., different length and width dimensions) of plate materials 42 can be placed on the two material racks respectively, the shearing machine 11 can shear the two types of plate materials 42, and the two types of strip materials 41 formed by shearing the two types of plate materials 42 flow to the first cutting device 50 and the second cutting device 60 respectively during the subsequent process, realizing mixed line production, i.e., simultaneously realizing production of two types of stamping parts.

[0030] As shown in Figure 1 and Figure 3As shown, in the embodiment, the feeding device 12 includes a first feeding mechanism 121 and a second feeding mechanism 122, the first feeding mechanism 121 is located between the first material rack 13 and the second material rack 14 and is used for conveying the plate material 42 to the shearing machine 11, and the second feeding mechanism 122 is used for conveying the plate material 42 on the first material rack 13 and the second material rack 14 to the first feeding mechanism 121. The first feeding mechanism 121 is located between the first material rack 13 and the second material rack 14, so that the moving distance of the second feeding mechanism 122 during feeding is small.

[0031] Specifically, in the embodiment, the first feeding mechanism 121 includes a placing platform provided with a plurality of rollers and a clamp, the clamp is driven by a motor cooperating with a ball screw to enable the clamp to move in a preset direction, and the clamp can clamp the end of the plate material 42 to push the plate material 42 to move on the placing platform and finally move to the shearing position of the shearing machine 11.

[0032] As shown in Figure 1 and Figure 3 , the second feeding mechanism 122 includes a mounting frame 1221 and a feeding suction cup 1222, the mounting frame 1221 has a crossbeam extending along the arrangement direction of the first material rack 13, the first feeding mechanism 121 and the second material rack 14, and the feeding suction cup 1222 is movably arranged along the crossbeam to convey the plate material 42 on the first material rack 13 and the second material rack 14 to the first feeding mechanism 121. Specifically, the mounting frame 1221 further includes two longitudinal beams arranged at both ends of the crossbeam, and the feeding is realized through the above structure, which has the advantage of simple structure.

[0033] Specifically, in the embodiment, the shunting device includes a detection part and a pushing part, the detection part can detect the width of the strip material 41 conveyed by the second conveying device 22, and the pushing part can push the strip material 41 on the second conveying device 22 onto the third conveying device 23. By detecting the width of the strip material 41, it is further judged whether the strip material 41 is conveyed to the first cutting device 50 or the second cutting device 60 next, which has the advantages of facilitating detection and process control. The pushing part can be a pneumatic cylinder, which is arranged at the intersection of the second conveying device 22 and the third conveying device 23. For example, when it is detected that the width of the strip material 41 is within a preset range, the strip material 41 is allowed to pass and continue to be conveyed downward by the second conveying device 22; when the width of the strip material 41 is not within the preset range, the pushing part is started to push the strip material 41 onto the third conveying device 23.

[0034] The production line of the embodiment further includes a control system connected with each processing device, which can adjust the processing according to the processing of each process. For example, the control system can further adjust which type of plate material 42 is used according to the feedback at the shunting device.

[0035] As shown in Figure 1 and Figure 3 , the first cutting device 50 includes a laser cutting machine 51 and a conveying clamp capable of placing the strip 41 conveyed by the second conveying device 22 to the cutting area of the laser cutting machine 51. The strip 41 is cut by the laser cutting machine 51 to form a block structure, which can realize high-precision machining and can be used for machining parts with high machining precision requirements.

[0036] The production line further includes a burr rolling device 70 arranged between the leveling device 30 and the first cutting device 50. Specifically, as shown in Figure 3 , the burr rolling device 70 is two friction wheels arranged at both ends of the second conveying device 22, which can remove burrs and the like on both sides of the strip 41.

[0037] As shown in Figure 1 , the production line further includes a first bending device 80 arranged downstream of the output end of the first cutting device 50. The first bending device 80 can bend the block structure conveyed from the first cutting device 50.

[0038] Specifically, the first bending device 80 includes a visual recognition system, a six-roller articulated robot, a bending machine, and an automatic positioning system, which can realize automatic recognition, accurate grabbing and placing of the workpiece, and further realize automatic bending. The workpiece (i.e., the block structure) processed by the first cutting device 50 is transported via a belt, and the end of the belt is a visual recognition area. After the workpiece is transported to the visual recognition area, a visual recognition system (specifically including a camera) takes a photo to automatically recognize the variety and position of the workpiece, and transmits the recognition information to a controller (specifically, a PLC). The controller controls the robot to accurately grab and position. The robot grabs the workpiece to the automatic positioning system, which includes a positioning platform and a cylinder structure arranged on the positioning platform. The cylinder structure can push the workpiece to make the workpiece align at the specified position to realize positioning, which facilitates the robot to grab the workpiece to the bending machine for subsequent bending operation. The six-roller articulated robot is a handling robot that can be directly purchased on the market. Since it is not the improvement point of the present application, its structure will not be described in detail.

[0039] As shown in Figure 1As shown, the second cutting device 60 comprises a punching machine 61 and a conveying assembly 62 arranged between the punching machine 61 and the third conveying device 23, the conveying assembly 62 being capable of placing the strip 41 on the third conveying device 23 to a punching position of the punching machine 61. The punching machine 61 punches the conveyed strip 41, which has the advantage of high efficiency. Specifically, the conveying assembly 62 comprises a stop correction mechanism, a centering system, a pneumatic lifting gripper, a servo module, etc. When the strip 41 is conveyed to this area, the front end of the strip 41 first contacts the stop correction mechanism, stops the forward movement, the centering system comprises two clamping mechanisms capable of clamping both sides of the strip 41 to achieve centering, the pneumatic lifting gripper descends and grabs the tail of the strip 41, and the servo module works to perform step-by-step feeding and cutting. Since the above-mentioned systems and mechanisms are conventional structures in the art and do not belong to the improvement points of the present application, the structures thereof will not be described in detail here.

[0040] In the present embodiment, through the cooperation of the punching machine 61 and the laser cutting machine 51, the production line of the present embodiment can process both parts with high precision requirements and parts with low precision requirements quickly.

[0041] Specifically, the production line further comprises a second bending device arranged downstream of the output end of the second cutting device 60. The second bending device is capable of bending the block-shaped structure conveyed from the second cutting device 60. The second bending device has substantially the same structure as the first bending device, and will not be described here.

[0042] Of course, in an embodiment not shown in the figure, the second bending device can also not be arranged, and the punching machine 61 is used to directly bend the parts.
