Description
Technical Field
[0001] The utility model belongs to the technical field of centering of a stamping production line, in particular to a centering device used in a stamping production line. Background Art
[0002] A stamping line is a production technology that uses a press and die to apply pressure to a material, causing it to plastically deform or separate, thereby creating a workpiece of the desired shape and size. Widely used in industries such as automotive manufacturing and metalworking, this line features high efficiency and a high degree of automation.
[0003] A stamping production line typically includes multiple units, such as depalletizing, loading and unloading, heating, stamping and cooling, and palletizing. These units are systematically integrated through industrial robots or manipulators to achieve automated production, thereby improving production efficiency and product quality.
[0004] There are three main types of stamping line automation: progressive die stamping, multi-station stamping, and tandem stamping. These methods, based on their respective characteristics, are applied to different production needs, such as the production of automotive sheet metal parts. Progressive die stamping is suitable for continuous production, multi-station stamping is suitable for processing complex parts, and tandem stamping is suitable for large-scale production.
[0005] In order to ensure that the sheet metal is accurately placed in the mold of the stamping equipment, the position of the sheet metal needs to be centered before the robot grabs it.
[0006] The traditional sheet metal centering method adopts a mechanical structure, that is, before the sheet metal enters the stamping equipment, the sheet metal is transferred to the block by a belt, and then the cylinders on the other three sides drive the punch to push it toward the center, so as to realize the centering of the sheet metal along the X-axis and Y-axis in the horizontal plane. Because the flapping distance of the flapping device of this centering method is relatively fixed, the fixed position of the flapping device needs to be adjusted accordingly for sheets of different sizes, and the operation is frequent and time-consuming; the stroke of the flapping cylinder is short. If the position deviation of the sheet metal is large, the flapping centering will fail. Utility Model Content

DETAILED DESCRIPTION
[0031] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.
[0032] like Figure 1-8 As shown, the utility model discloses a centering device for a stamping production line, including a belt conveyor mechanism 100 and a support platform 200; the support platform 200 includes a lower connecting frame 23 at the bottom and an upper connecting frame 21 connected to the bottom of the belt conveyor mechanism 100; three lower connecting seats 24 evenly arranged at annular intervals are connected to and installed on the lower connecting frame 23, and three upper connecting seats 22 evenly arranged at annular intervals are connected to and installed on the upper connecting frame 21; and the projections of the lower connecting seats 24 and the upper connecting seats 22 in the vertical direction are evenly spaced from each other; each lower connecting seat 24 is connected to and installed with two driving telescopic cylinders 25 connected to two adjacent upper connecting seats 22.
[0033] During use, the sheet material is conveyed by the transition belt to the belt conveyor mechanism 100 of the centering device, and the sheet material position offset information is collected by laser scanning. The sheet material's position in the X direction is adjusted by controlling the belt conveyor mechanism 100. The six driving telescopic cylinders 25 cooperate with the telescopic action to achieve six-degree-of-freedom adjustment of the belt conveyor mechanism 100, thereby enabling the belt conveyor mechanism 100 to perform actions such as lifting, rotating, translating, and tilting, thereby achieving flexible adjustment of the sheet material position to match the set grasping position of the grasping robot, placing the sheet material into the stamping equipment 300 for stamping operations. The overall structure is simple, and the adjustment of the sheet material's posture is flexible, convenient, and efficient. It has a wide range of uses, effectively improves the automation level of the stamping production line, and has good practicality.
[0034] Among them, the centering device can be used in parallel, such as Figure 1-3 As shown, for longer plates, multiple centering devices are used to achieve reliable and stable support for the plates.
[0035] Among them, Figure 1 、2 As shown in Figures 6, 7, and 8, the belt conveyor mechanism 100 includes a mounting frame 11, a plurality of parallel conveyor belts 14 mounted on the upper side of the mounting frame 11, and a motor 15 capable of synchronously driving the plurality of conveyor belts 14 in forward and reverse rotation. The upper sides of three upper connecting seats 22 are connected to the bottom support of the mounting frame 11. By driving the plurality of conveyor belts 14 in forward and reverse directions by the motor 15, flexible adjustment of the X-direction of the supported sheet material can be achieved. When two centering devices are used, the conveyor belts 14 on the two centering devices rotate in opposite directions, enabling rotational adjustment of the long sheet material supported on the conveyor belts 14.
[0036] Among them, a plurality of support rollers 16 spaced apart along the length direction are installed between adjacent conveyor belts 14. Auxiliary rolling support for the sheet material is achieved to avoid excessive downward pressure on the conveyor belt 14 to damage it.
[0037] The mounting frame 11 is a frame structure with four support plates 12 welded to its lower side. A square mounting plate 13 is welded to the lower side of the four support plates 12. The lower side of the mounting plate 13 is connected to the three upper connecting seats 22. This ensures that the support frame 200 can reliably and stably support and connect the belt conveyor mechanism 100.
[0038] The lower connecting frame 23 comprises three lower connecting beams, each of which is fixed at one end and connected to three lower connecting seats 24 at the other end. Adjacent lower connecting beams have the same angle. The upper connecting frame 21 comprises three upper connecting beams, each of which is fixed at one end and connected to three upper connecting seats 22 at the other end. Adjacent upper connecting beams have the same angle. The lower connecting frame 23 and the upper connecting frame 21 have simple structures, are easy to form, and have good stability.
[0039] Furthermore, both the lower and upper connecting beams are made of I-beams, which are easy to form and have high structural strength, ensuring reliable and stable support.
[0040] The upper connecting seat 22 comprises an upper connecting seat base of an I-beam structure, with upper connecting seat end plates welded to both ends of the upper connecting seat base. The upper connecting seat 22 has a simple structure, is easy to form, and has high structural strength.
[0041] The lower connector 24 comprises an I-beam steel structure with a base plate welded to the bottom. Trapezoidal end plates are welded to each end of the base, and the bottoms of the end plates are welded to the base plate. The base plate is fixedly connected to the foundation. Lower connector 24 has a simple structure, is easy to form, and has high structural strength.
[0042] The two ends of the driving telescopic cylinder 25 are respectively connected to the lower connecting seat 24 and the upper connecting seat 22 through the universal connecting seat 26. This realizes the flexibility of the driving telescopic cylinder 25 in terms of telescopic and rotating movements, eliminates stress at both ends of the driving telescopic cylinder 25, and improves the service life of the driving telescopic cylinder 25.
[0043] The vertical projections of the upper connecting seat 22 and the lower connecting seat 24 are on the same circumference, that is, the distance between the upper connecting seat 22 and the center is equal to the distance between the lower connecting seat 24 and the center, thereby achieving flexible adjustment and a compact structure.
[0044] This centering device for a stamping production line is used. When in use, the sheet metal is conveyed by a transition belt to the belt conveyor mechanism 100 of this centering device, and the sheet metal position offset information is collected by laser scanning. The sheet metal position in the X direction is adjusted by controlling the belt conveyor mechanism 100. The six driving telescopic cylinders 25 cooperate with the telescopic action to achieve six-degree-of-freedom adjustment of the belt conveyor mechanism 100, thereby enabling the belt conveyor mechanism 100 to perform actions such as lifting, rotating, translating, and tilting, thereby achieving flexible adjustment of the sheet metal position to match the set grasping position of the grasping robot, placing the sheet metal into the stamping equipment 300, and performing the stamping operation. The overall structure is simple, the sheet metal posture adjustment is flexible, convenient, and efficient, and it has a wide range of uses. It effectively improves the automation level of the stamping production line and has good practicality.
