Technical Field

[0001] The invention relates to the technical field of stainless steel stamping, and in particular to one-step stamping forming equipment and method based on stainless steel vessel processing. Background Art

[0002] Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, etc. or has stainless properties is called stainless steel. Utensils made of stainless steel have excellent impact resistance. Stamping is a forming method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. Stamping and forging are both plastic processing, collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Among the steel materials in the world, 60-70% are plates, most of which are stamped into finished products. The car body, chassis, fuel tank, radiator fins, boiler drums, container shells, motors, electrical iron core silicon steel sheets, etc. are all stamped. There are also a large number of stamping parts in products such as instruments, household appliances, bicycles, office machinery, and daily utensils. In the process of producing and processing stainless steel utensils, stamping forming is often used to improve the sealing performance and storage capacity of stainless steel utensils.

[0047] A method for using a one-step stamping and forming device based on stainless steel vessel processing, using the one-step stamping and forming device based on stainless steel vessel processing as described above, comprising the following steps:

[0048] Step 1: After the staff places the stainless steel plate on the punching table 2, the driving motor 520 is started, and the rotating disc 515 on the adjusting cylinder 514 is driven to rotate by the driving motor 520, so that the rotating shaft 1 516 on the rotating disc 515 drives the push-pull rod 518 to drive the adjusting slide 503 on the rotating shaft 2 517 to move in the slide groove on the punching table 2 at the same time, so that the central adjusting plate 509 on the support rod 507 on the L support rod 505 on the adjusting slide 503 moves at the same time;

[0049] Step 2: Push the corner of the stainless steel plate through the center adjustment plate 509, so that the stainless steel plate moves to the center position of the stamping;

[0050] Step 3: When the center adjustment plate 509 contacts the corner of the stainless steel plate, the extrusion force generated by the contact is buffered by the telescopic spring 508 and the extrusion spring 1 512 to prevent the extrusion force from deforming the side of the stainless steel plate.

[0051] Working principle: When the staff puts the stainless steel plate on the punching table 2, the driving motor 520 is started, and the rotating disc 515 on the adjusting cylinder 514 is driven to rotate by the driving motor 520, so that the rotating shaft 1 516 on the rotating disc 515 drives the push-pull rod 518 to drive the adjusting slide 503 on the rotating shaft 2 517 to move in the slide groove on the punching table 2 at the same time, so that the center adjustment plate 509 on the support rod 507 on the L support rod 505 on the adjusting slide 503 moves at the same time, and the center adjustment plate 509 The corner of the stainless steel plate is pushed, so that the stainless steel plate moves to the center of the stamping. When the center adjustment plate 509 contacts the corner of the stainless steel plate, the extrusion force generated by the contact is buffered by the telescopic spring 508 and the extrusion spring 512 to prevent the extrusion force from deforming the side of the stainless steel plate. During stamping, the stamping lifting platform 603 is driven by the stamping machine 601 to move outside the limiting cylinder 602, so that the upper mold 604 at the bottom of the stamping lifting platform 603 presses the lower mold 512 on the stamping platform 2. The stainless steel plate on the U-shaped mounting frame 615 is pressed to produce plasticity. During the movement of the punching lifting platform 603, the elasticity of the extrusion spring 2 614 located inside the punching lifting platform 603 causes the ball 616 on the U-shaped mounting frame 615 to abut against the outer wall of the limiting cylinder 602. The contact area between the ball 616 and the outer wall of the limiting cylinder 602 is small, thereby reducing the friction with the outer wall of the limiting cylinder 602 and improving its service life. At the same time, when the punching lifting platform 603 moves downward, the opening and closing rod 612 is driven by the top rod 611 to move relatively, so that the middle The hollow arc-shaped blower frame 607 is aligned with the stamping area, and the condensation box 605 is started at the same time. Cold air is blown into the hollow arc-shaped blower frame 607 through the hose 606, and then the stamping area is cooled down to avoid the mold accumulating heat during continuous stamping and affecting the stamping. During the continuous stamping process, the staff intermittently pushes the push-pull cylinder 12, and the push-pull cylinder 12 drives the push-pull slide plate 9 to drive the movable plate 11, so that the connecting spring 7 on the lifting plate 8 drives the lower mold 523 to shake, thereby detecting the connection of the lower mold 523.
