Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal forming, in particular to a precise sheet metal forming rapid forming device. Background Art

[0002] Sheet metal forming is a processing method that applies external force to metal raw materials such as thin plates, thin-walled profiles and thin-walled pipes to cause them to undergo plastic deformation or shear, thereby becoming parts with the desired shape and performance.

[0003] Products processed through sheet metal technology are called sheet metal parts. Different industries generally refer to different sheet metal parts. Currently, sheet metal processing is carried out through sheet metal rapid prototyping devices.

[0004] For example, the prior art Chinese patent publication number "CN210208229U" provides a precision sheet metal rapid prototyping device, including a base, four upright columns erected at the four corners of the top of the base, a support plate horizontally sleeved in the middle of the columns, a honeycomb panel sealed between the support plate and the top of the base, and a movable door provided on the front end of the honeycomb panel.

[0005] The device can absorb the noise during stamping through the honeycomb panel. At the same time, the sound-absorbing cotton filled in the honeycomb panel can also perform secondary noise absorption, reducing the noise to a minimum, effectively preventing the noise from causing harm to people's health and affecting their work efficiency. At the same time, the designed ejection mechanism can eject the stamped sheet metal parts from the die mechanism to prevent the sheet metal parts from being stamped again due to failure to be removed in time after stamping. When the punch stamps the sheet metal part, the top plate moves downward to squeeze the spring to make space in the carrier tube.

[0006] The existing precision sheet metal rapid prototyping device, after forming the sheet metal parts, will form piles and bumps against each other after the formed sheet metal parts fall, resulting in scratches and bumps on the surface of the sheet metal parts, and the sheet metal parts cannot be evenly moved and discharged after forming. At the same time, when the sheet metal parts are stamped and formed, there will be impact and vibration, and the thin plate raw material will be shaken and moved, resulting in deviations in the forming position on the thin plate raw material, and the thin plate raw material cannot be pressed and stabilized.
