Description

Technical Field

[0001] The invention relates to the technical field of stamping part curling, in particular to a stamping part curling structure. Background Art

[0002] Stamping is a forming method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the steel in the world is plate material, most of which is made into finished products by stamping. The car body, chassis, fuel tank, radiator fins, boiler drum, container shell, motor, electrical core silicon steel sheet, etc. are all stamped. There are also a large number of stamping parts in products such as instruments and meters, household appliances, bicycles, office machinery, and daily utensils.

[0003] Stamping can produce workpieces with reinforcing ribs, ribs, undulations or flanging that are difficult to manufacture by other methods, in order to improve their rigidity. Due to the use of precision molds, the workpiece accuracy can reach micron level, and the repeatability is high and the specifications are consistent. Holes, bosses, etc. can be stamped out. Cold stamping parts generally do not undergo cutting processing, or only require a small amount of cutting processing. The accuracy and surface condition of hot stamping parts are lower than those of cold stamping parts, but are still better than castings and forgings. The amount of cutting processing is small. After the ordinary molds curl the edges and corners of the stamping parts, they must go through pre-bending, flanging, pressing and other processes, which are very cumbersome to make, making the curling speed of the stamping parts too slow, affecting industrial production efficiency. Therefore, the market urgently needs to develop a stamping part curling structure to help people solve existing problems. Summary of the invention

[0021] Furthermore, a distribution box 14 is installed inside the chassis 2, and a circuit tube is arranged above the distribution box 14. The circuit tube passes through the second working box 3 and is connected to the wall cabinet 4. The chassis 2 is made of high-strength imported synthetic steel with high yield strength, not easy to deform, strong load-bearing capacity and long service life.

[0022] Furthermore, a hydraulic pump 20 is installed inside the wall cabinet 4, a hydraulic pipe 21 is installed on one side of the hydraulic pump 20, and the other side of the hydraulic pump 20 is electrically connected to the circuit pipe. An oil branch pipe is arranged below the hydraulic pipe 21, and there are two oil branch pipes.

[0025] Working principle: When using this equipment to curl the stamped parts, first place the stamped steel plate on the top of the first working box 1, start the hydraulic pump 20, and the hydraulic pump 20 will transport hydraulic oil to the inside of the first hydraulic top 22 and the second hydraulic top 23 through the hydraulic pipe 21, so that the hydraulic top will lower the curling block 6 until it fits with the stamped steel plate, and keep the stamped steel plate under pressure so that the stamped steel plate will not move when it is bent by external force. When the stamped steel plate is firmly fixed, start the servo motor 25 inside the first working box 1, so that the servo motor 25 drives the first turntable 10 after deceleration through the first reduction box 9. At this time, the first eccentric wheel 11 will make a circular motion around the center of the first turntable 10, so that the first drive arm 12 keeps rising and falling. , so that the first connecting leg 13 keeps rising and falling, so that the first curling arm 7 keeps rising and falling to extrude different stamped steel plates, so that the inner circle of the stamped steel plate fits with the arc surface of the curling block 6, and then the servo motor 25 inside the second working box 3 is started. The servo motor 25 will use the same mechanical principle as the internal structure of the first working box 1 to make the second curling arm 8 keep squeezing the stamped steel plate, so that the edge of the stamped steel plate forms a curling. By making the first curling arm 7 and the second curling arm 8 work alternately in sequence, and arranging an automatic collection device on one side of the equipment, the stamped parts with completed curling can be quickly removed from the top of the curling block 6, so that the curling of the stamped parts can be realized in assembly line production, thereby improving the efficiency of curling.
