Description

Technical Field

[0001] The utility model belongs to a material supporting structure for thermoforming processing, in particular to a novel anti-scratch material supporting tongue for thermoforming processing. Background Art

[0002] Currently, stamping and drawing dies with a raised center section on the blanking surface utilize a support structure to horizontally support the sheet metal, ensuring stable and accurate feeding. Stamping and drawing dies consist of a matching upper and lower die, with a blank holder attached to the edge of the lower die. The support structure is secured to the blank holder.

[0003] Chinese patent publication number CN213002215U discloses a stamping die support positioning structure and stamping die assembly. The structure includes a positioning plate and a rotating shaft mounted on the plate. It also includes a support weight extending through the plate and rotatably connected to the plate via the rotating shaft. A gap exists between the support weight and the plate. At least one magnet is positioned within the gap, each magnet being fixedly connected to the plate and capable of attracting the support weight.

[0004] However, the above patent has the following shortcomings:

[0005] The above-mentioned patented material support counterweight relies on the suction force provided by the magnet and the weight of the material support counterweight itself to balance the weight of the sheet and the impact force generated by the feeding. The required material support counterweight is small in size, the entire stamping die material support positioning structure occupies a small space, and the avoidance space required for the upper die to be processed is also relatively small. However, the above-mentioned patent is not convenient for adjusting the device's counterweight and the suction force of the magnet according to the weight of the workpiece, thereby reducing the scope of application of the device.
