Description

Technical Field

[0001] The invention relates to the technical field of stamping production lines, in particular to an automatic feeding and unloading device for a stamping production line. Background Art

[0002] Stamping is a pressure forming process in which a die mounted on a press applies pressure to a material at room temperature, causing it to separate or plastically deform, thereby producing the desired part. Stamping involves applying external force to sheet, strip, tube, and profiles using a press and die, causing them to plastically deform or separate, thereby producing a workpiece (stamped part) of the desired shape and size. Stamping and forging are both types of plastic working (or pressure working), collectively known as forging. Stamping materials are primarily hot-rolled and cold-rolled steel sheets and strips. 60-70% of the world's steel production consists of sheet metal, much of which is stamped into finished products. Automotive bodies, chassis, fuel tanks, radiators, boiler drums, container housings, and the silicon steel cores of motors and electrical appliances are all stamped. Instruments, home appliances, bicycles, office machinery, and household utensils also contain a large number of stamped parts. Stamping is a production technique that uses the power of conventional or specialized stamping equipment to subject sheet metal to direct deformation forces within a die, thereby deforming the material to a desired shape, size, and performance. The sheet metal, the die, and the equipment are the three essential elements of stamping. Stamping is categorized into hot stamping and cold stamping based on the processing temperature. The former is suitable for processing sheet metal with high deformation resistance and poor plasticity; the latter, performed at room temperature, is a commonly used stamping method for thin sheets. It is one of the main methods of metal plastic working (or pressure working) and falls under the umbrella of material forming engineering. However, when stamping certain specialized workpieces, such as mobile phone casings, decorative components within the casing must first be placed within the casing, then manually pressed tightly by a worker before being fed to the bottom side of a stamping machine and pressed by the punch. This operation is time-consuming and labor-intensive, and the feed mechanism typically requires two or more power sources. This excessive number of power sources increases production costs. Therefore, those skilled in the art have provided an automatic feeding and unloading device for a stamping production line to address the problems outlined in the background art.

[0029] Working principle: put the workpiece to be pre-pressed into the pre-pressing groove 4 through the discharge port 403, and then start the external servo motor. When the servo motor drives the first gear 2 to rotate, the first gear 2 and the second gear 202 and the third gear 203 rotate. When the third gear 203 rotates, it drives the first connecting rod 204 to rotate. The first connecting rod 204 drives the second connecting rod 205 to swing. When the second connecting rod 205 swings, it pushes the seventh connecting rod 210 to reciprocate through the fourth connecting rod 207. When the seventh connecting rod 210 reciprocates, it drives the pre-pressing groove 4. The pressing block 218 slides inside the pre-pressing groove 4 to pre-press the components inside the pre-pressing groove 4. At the same time, when the first gear 2 rotates, it drives the cam 201 to rotate, wherein the cam 201 drives the roller 214 to swing back and forth when rotating, and the roller 214 drives the eighth connecting rod 213 to move up and down when swinging, thereby driving the pushing plate 217 to move up and down inside the pushing groove 402, so that the components pre-pressed by the pre-pressing block 218 can be pushed out through the pushing groove 402, and then the pressed components are pushed out by the first cylinder 5. The components inside the stamping groove 102 are pushed into the stamping groove 102 through the sliding groove 101. After being stamped by the stamping machine 9, the components inside the stamping groove 102 are pushed into the conveyor belt 8 on the unloading platform 7 through the second cylinder 6, which is convenient for transporting the components after stamping. The first gear 2 in the feeding structure is provided with only one power source to complete the material transportation and pre-pressing, reducing costs, and the structure is simple, which is convenient for subsequent maintenance. The buffer block 301 on the buffer tube 3 plays a buffering and protective role on the pre-pressing block 218. When the buffer block 301 is squeezed by the pre-pressing block 218, the piston 30 When the pre-loading block 218 moves inside the buffer tube 3, the air inside the buffer tube 3 moves into the airbag 303, causing the airbag 303 to swell. Thus, the airbag 303 and the buffer block 301 provide a buffer for the pre-loading block 218, thereby preventing the pre-loading block 218 from colliding with components inside the pre-loading groove 4, preventing damage to the components, and prolonging the service life of the components. When the pre-loading block 218 leaves the buffer block 301, the airbag 303 is reset due to its own elastic material, and the gas inside the airbag 303 returns to the buffer tube 3, causing the buffer block 301 to return to its original position.
