Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to an automatic feeding device for automobile body stamping parts. Background Technology

[0002] The automotive body stamping parts feeding device is an automated equipment mainly used to accurately and efficiently transport metal sheets or pre-formed blanks to stamping machines for forming. This device typically consists of a feeding mechanism (such as a robotic arm, conveyor belt, or suction cup handling system), positioning fixtures, and a control system. It enables high-speed, stable, and continuous feeding, ensuring the precision and consistency of the stamping process.

[0003] Chinese patent CN220347042U discloses an automotive stamping parts feeding mechanism, including a base, a housing fixedly connected to the top of the base, an operating table slidably connected to the top of the base and inside the housing, a fixing plate fixedly connected to one side of the housing, and a hydraulic cylinder fixedly connected to the bottom of the fixing plate. The advantage of this device is that automotive parts are placed sequentially into the housing. Activating the hydraulic cylinder moves the lower pressure plate downwards, causing the stamping head to move downwards and stamp the automotive parts. Simultaneously, the downward movement of the lower pressure plate drives the connecting shaft to rotate, pushing the operating table to one side. The operating table pushes the bottommost automotive part to below the stamping head. After the stamping head stamps the automotive part, the hydraulic cylinder retracts, causing the operating table to reset. A baffle prevents stamped parts from entering the housing. With the reactivation of the hydraulic cylinder, a new automotive part is pushed out of the housing, thus allowing for piece-by-piece feeding. However, this device still has the following problems:

[0004] 1. After the device loads automotive stamping parts, the operating table needs to be moved and reset. However, when the stamping material is a heavy steel plate, the excessive friction will cause the steel plate to move when the operating table is reset, which will damage the stop block.

[0005] 2. This device cannot accurately position the raw materials when processing stamped parts, resulting in alignment errors that affect product quality.

[0006] Based on this, this utility model designs an automatic feeding device for automobile body stamping parts to solve the above problems. Utility Model Content

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 An automatic feeding device for automobile body stamping parts includes a base 1;

[0033] An automatic board feeding mechanism 2 for feeding boards one by one according to the thickness of the board is installed on the left side of the base 1;

[0034] An automatic alignment and ejection mechanism 3 is installed on the base 1 for positioning the plate and ejecting the processed plate from the mold;

[0035] A stamping machine 4 for stamping sheet metal is installed on the base 1; an upper template is fixedly installed at the lower end of the stamping machine 4, and a lower template is fixedly installed at the upper end of the base 1.

[0036] like Figure 2 As shown, the automatic board feeding mechanism 2 includes a feeding drive assembly 21, a board storage assembly 22, and a thickness adjustment assembly 23; both the board storage assembly 22 and the thickness adjustment assembly 23 are connected to the feeding drive assembly 21; the board storage assembly 22 is connected to the thickness adjustment assembly 23; the feeding drive assembly 21 is used to drive the board feeding, and the board storage assembly 22 is used to store the board; the thickness adjustment assembly 23 is used to adjust the thickness of the board so that the feeding drive assembly 21 can feed the board one by one.

[0037] The stamping press 4 adopts existing mature technologies in the field, such as a high-efficiency stamping press for automotive parts disclosed in Chinese patent CN221890683U, which will not be elaborated on here.

[0038] In this invention, the operator places the sheet metal to be stamped into the sheet metal storage component 22, and then adjusts the thickness adjustment component 23 according to the sheet metal thickness so that the feeding drive component 21 can drive the sheet metal to be fed one by one; then the feeding drive component 21 is started to transport the sheet metal one by one to the automatic alignment and ejection mechanism 3. After the automatic alignment and ejection mechanism 3 clamps and positions the sheet metal in the center, the stamping machine 4 stamps the sheet metal, and after stamping, the automatic alignment and ejection mechanism 3 will eject the workpiece from the lower mold; thus realizing automatic feeding and centering of the sheet metal.

[0039] The feeding drive assembly 21 includes a belt conveyor 211 and push blocks 212; multiple push blocks 212 are fixedly arranged at equal intervals on the outer side of the belt of the belt conveyor 211; the sheet material storage assembly 22 and the thickness adjustment assembly 23 are both connected to the belt conveyor 211.

[0042] In this utility model, the operator places the sheet material to be stamped in the storage bin 221, and then tightens the screw 231. The screw 231 drives the slide plate 232 to slide in the vertical direction along the fixed frame 233, so that the distance between the lower end of the slide plate 232 and the upper end of the belt of the belt conveyor 211 is adapted to the thickness of the sheet material. Then the belt conveyor 211 starts and drives the push block 212 to rotate clockwise. After the push block 212 passes through the clearance groove 222, it pushes the sheet material at the bottom of the storage bin 221 to move to the right. The sheet material passes under the slide plate 232 to the right, realizing the feeding of the sheet material one by one.

[0043] like Figure 2As shown, the automatic alignment and ejection mechanism 3 includes an alignment drive assembly 31, an alignment assembly 32, and an ejection assembly 33; the base 1, the alignment assembly 32, and the ejection assembly 33 are all connected to the alignment drive assembly 31; the alignment assembly 32 and the ejection assembly 33 are both connected to the base 1; the alignment drive assembly 31 is used to drive the alignment assembly 32 and the ejection assembly 33; the alignment assembly 32 is used to center and position the sheet metal, and the ejection assembly 33 is used to eject the processed workpiece after stamping;

[0044] The alignment drive assembly 31 includes a double-stroke cylinder 311 and a vertical moving block 312; the double-stroke cylinder 311 is fixedly connected to the lower end of the base 1, and the drive end of the double-stroke cylinder 311 is fixedly connected to the vertical moving block 312; the alignment assembly 32 and the top material assembly 33 are both connected to the vertical moving block 312.

[0045] The alignment component 32 includes a centering positioning component and a guide block 323; there are two sets of centering positioning components; the two sets of centering positioning components are symmetrically arranged on the base 1, the guide block 323 is connected to the centering positioning component, and the base 1 and the vertical moving block 312 are both connected to the centering positioning component.

[0046] The centering positioning component includes a connecting rod 321 and a clamping block 322; the lower end of the connecting rod 321 is hinged to the vertical moving block 312, and the upper end of the connecting rod 321 is hinged to the clamping block 322; a limiting groove 324 is provided on the upper end of the base 1; the clamping block 322 is slidably connected along the limiting groove 324; the left end of the clamping block 322 near the belt conveyor 211 is fixedly connected to the guide block 323; the guide block 323 is arc-shaped on the side near the plate to guide the plate into the clamping block 322;

[0048] In this invention, the pusher block 212 conveys the plate to the top of the base 1. The plate is supported by two top support rods 331. Then, the double-stroke cylinder 311 drives the vertical moving block 312 to move downward. The top support rods 331 move the plate downward. At the same time, the vertical moving block 312 drives the clamping blocks 322 to move closer to each other along the limiting groove 324 via the connecting rod 321. The clamping block 322 closest to the belt conveyor 211 guides the plate to be aligned by the guide block 323. Then, the two clamping blocks 322 are positioned in the center. During the positioning process, the top support rods 331 continue to move downward. The plate is lowered, and the support of the plate is changed from the top support rod 331 to the lower template. After the alignment is completed, the double-stroke cylinder 311 moves upward and drives the clamping block 322 to move away from each other to avoid the upper template through the connecting rod 321. At this time, the height of the top support rod 331 is still lower than the lower template. Then the stamping machine 4 drives the upper template and the lower template to approach the stamping plate. After the stamping is completed, the double-stroke cylinder 311 drives the vertical moving block 312 to move the top support rod 331 upward to push out the processed workpiece for easy unloading. This realizes the centering and positioning of the plate before stamping and the automatic ejection of the workpiece after stamping.
