Description

Technical Field

[0001] The invention belongs to the field of stamping process equipment, and in particular relates to an anti-deviating stamping device for automobile parts. Background Art

[0002] Stamping is a forming process that uses a press and die to apply external force to sheet metal, strip, tube, and profiles, causing them to plastically deform or separate, thereby obtaining a workpiece (stamped part) of the desired shape and size. However, current presses on the market are prone to material misalignment during operation. This can affect the quality of the finished automotive parts, resulting in suboptimal stamping results and poor production quality. Patent publication number CN108526319A discloses a multifunctional anti-drift stamping device for automotive parts, comprising a first mounting plate, a second mounting plate, a fixing plate, a positioning plate, a forming mechanism, and a stamping mechanism. The positioning plate is provided with N positioning holes evenly distributed circumferentially and extending through its upper and lower surfaces. N forming dies are arranged between the fixing plate and the positioning plate and evenly distributed circumferentially. The stamping mechanism has a fixed frame, a turntable, a loading assembly, a cutting assembly, a forming assembly, and a first drive mechanism. The loading assembly is mounted on the end of the third support rod away from the turntable, the cutting assembly is mounted on the end of the second support rod away from the turntable, and the forming assembly is mounted on the end of the first support rod away from the turntable. This technology achieves automatic loading by providing a loading assembly, thereby improving production efficiency. The positioning plate is provided to position the raw material to prevent it from drifting during processing. However, this device cannot position and prevent drift for raw materials of different widths during processing, which is limited in its scope of application. In addition, some existing technologies have a shock-absorbing method in the lower plate to reduce impact force, which makes the lower plate unstable during operation and easily causes the angle of the stamped parts to be non-standard. Summary of the Invention

[0003] The purpose of the present invention is to provide an anti-deviating stamping device for automobile parts, which is suitable for stamping sheets of different widths and thicknesses, while increasing the stability of the lower plate and improving the stamping quality.

[0004] The technical solution adopted by the present invention is:

[0005] An anti-deviating automobile parts stamping device includes a stamping table and a stamping machine. A stamping lower plate is provided on the stamping table, and a stamping lower die is provided in the stamping lower plate. The stamping machine includes a stamping seat, a hydraulic cylinder is fixed on the horizontal section of the stamping seat, a stamping upper plate is fixed on the telescopic head of the hydraulic cylinder, and a stamping upper die is provided in the stamping upper plate. A sliding column is fixed on the stamping upper plate, and the sliding column is slidably connected to the horizontal section of the stamping seat and is provided with a shock-absorbing spring.

[0006] Furthermore, the stamping lower plate is arranged on the table surface of the stamping table and can move up and down;

[0007] The stamping upper plate is slidably connected to the vertical section of the stamping seat, and a number one bar tooth is fixed on both sides of the stamping upper plate; a number one spur gear and a number two spur gear that mesh with each other are rotatably provided on the vertical section of the stamping seat, and the number one spur gear is meshed with the number one bar tooth;

[0008] No. 2 bar teeth are fixed on both sides of the stamping lower plate, and the No. 2 bar teeth are meshed and connected with the No. 2 spur gear; a supporting mechanism is movably provided under the stamping lower plate.

[0009] During operation, the sheet to be stamped is placed on the table. When the hydraulic cylinder drives the stamping upper plate to move downward, it drives the No. 1 bar gear downward, and then uses the No. 1 spur gear and the No. 2 spur gear to drive the No. 2 bar gear upward. The No. 2 bar gear drives the stamping lower plate upward, realizing the relative movement of the stamping lower plate and the stamping upper plate, while approaching the sheet to be stamped. When the stamping lower plate passes from the bottom of the table to the top of the table, it gives the sheet to be stamped an upward force to achieve a close fit between the two. At the same time, the stamping upper plate is also close to the upper side of the sheet to be stamped; after that, the support mechanism holds the stamping lower plate, and then the hydraulic cylinder applies an impact force to stamp the sheet. During the stamping process, the stamping lower plate remains stable and the generated stamping reaction force is absorbed by the shock-absorbing spring. Setting two relatively moving stamping lower plates and stamping upper plates can clamp the sheet before the stamping operation to prevent deviation.

[0010] Furthermore, a positioning mechanism is provided on the stamping table, which includes a rotating shaft rotatably arranged on the stamping table surface, a shift lever fixed on the rotating shaft, a sliding rod parallel to the rotating shaft provided below the shift lever, the sliding rod is slidably connected to the arc groove on the stamping table surface, and a number of extrusion springs are provided on one side of the shift lever; a sector toothed disc is fixed on the rotating shaft, and the sliding rod is fixedly connected to the sector toothed disc; a No. 1 transmission shaft and a No. 2 transmission shaft are rotatably provided below the stamping table, a No. 3 spur gear and a No. 4 spur gear are respectively fixed at both ends of the No. 1 transmission shaft, and a No. 5 spur gear and a No. 6 spur gear are respectively fixed at both ends of the No. 2 transmission shaft, wherein the No. 4 spur gear is meshed with the No. 6 spur gear, and the No. 3 spur gear is meshed with the sector toothed disc;

[0011] A number three bar tooth is slidably provided in the punching table, the number three bar tooth is meshed and connected with the number five spur gear, and a positioning clamp is provided on the number three bar tooth.

[0012] During operation, when the sheet metal is pushed from the stamping table to the stamping lower plate, the lever is turned to one side and the extrusion spring is compressed. The extrusion spring can ensure that the lever is always close to the sheet metal; during the rotation of the lever, the slide bar is driven to slide along the arc groove, driving the sector gear plate to rotate synchronously, and then, the No. 3 bar tooth is driven to move toward the outside of the stamping table through the No. 3 spur gear, No. 4 spur gear, No. 6 spur gear, and No. 5 spur gear in sequence, and then the positioning splint and the lever are driven to rotate synchronously, so that the positioning splint can adapt to sheets of different widths.

[0013] Furthermore, a feeding mechanism is provided on one side of the table surface of the punching table. The feeding mechanism includes a lower belt conveyor and an upper belt conveyor. A motor is connected to a rotating shaft of the lower belt conveyor.

[0014] The lower belt conveyor and the upper belt conveyor clamp the sheet material for transportation.

[0015] Furthermore, a long limit seat is provided on the front side of the lower belt conveyor and the upper belt conveyor, several notches are provided on the long limit seat, a long limit plate is provided on the long limit seat, the protrusions on the long limit plate match the notches, and the long limit plate is connected to the long limit seat by sliding up and down.

[0016] The long limit plate and the long limit seat assist the sheet metal in advancing and prevent it from deflecting during the advancement process.

[0017] Furthermore, the rotating shaft of the upper belt conveyor is set in the long limit seat for sliding up and down. A connecting plate is fixed on the rotating shaft of the upper belt conveyor, and a No. 4 bar tooth is fixed on the lower side of the connecting plate. A No. 1 gear is rotatably provided on the long limit seat, and the No. 1 gear is meshed and connected with the No. 4 bar tooth.

[0018] By cooperating with the No. 1 gear and the No. 4 strip tooth, the vertical distance between the upper belt conveyor and the lower belt conveyor is adjusted to adapt to plates of different thicknesses.

[0019] Furthermore, a number five bar tooth is fixed on the long limit plate, a number two gear is rotatably provided on the long limit seat, and the number two gear is meshed and connected with the number five bar tooth.

[0020] Furthermore, an L-shaped indicator strip is provided on the fifth bar-shaped tooth, and one end of the connecting plate is overlapped on the L-shaped indicator strip.

[0021] By setting overlapping connecting plates and L-shaped indicator strips, the adjustment height of the long limit plate and the upper belt conveyor can be checked in real time to keep them consistent.

[0022] Furthermore, the support mechanism includes a pillar fixedly connected to the bottom surface of the stamping lower plate, and a connecting rod No. 1 is hinged on both sides of the pillar. A square slide is rotatably connected on both sides of the stamping table. The connecting rod No. 1 is slidably set in the square slide, and the connecting rod No. 1 is hinged to a horizontal support block through the connecting rod No. 2.

[0023] When the stamping lower plate is under the table, the horizontal support block is on the outside of the stamping table and has no effect on the up and down movement of the stamping lower plate; when the stamping lower plate moves upward, it drives the pillar to move upward, and the pillar drives the No. 1 connecting rod to move obliquely upward in the square slide, and then pushes the horizontal support block into the stamping table through the No. 2 connecting rod until it is under the stamping lower plate, and supports the stamping lower plate.

[0024] Furthermore, the stamping lower die is movably installed in the stamping lower plate, and the stamping upper die is movably installed in the stamping upper plate.

[0025] The movable installation can adapt to different stamping shape requirements and can be replaced at any time.

[0026] Beneficial effects of the present invention:

[0027] Two relatively moving stamping lower plates and stamping upper plates are set up to clamp the sheet before the stamping operation to prevent deviation; by setting linkage components such as shift rods and spur gears and positioning clamps that can move synchronously, the positioning clamps can adapt to sheets of different widths and clamp the sheets in real time; up and down movable belts and long limit plates are set up to realize automatic conveying of sheets and can adapt to sheets of different thicknesses; the movable installation can adapt to different stamping shape requirements and can be replaced at any time.
