Location support device for hot stamping plates

Abstract

The invention discloses a location support device for hot stamping plates, comprising a bottom plate arranged horizontally, an extension spring vertically mounted in the middle of the bottom plate, a guide sleeve sleeved outside the extension spring, and a support block supporting above the spring; two sides of the bottom plate are provided with strip mounting holes; the guide sleeve comprises an upper sleeve and a lower sleeve, an upper end of the upper sleeve is fixed on a lower surface of the support block, a lower end of the lower sleeve is fixed on the surface of the bottom plate, the lower end of the upper sleeve is glidingly sleeved with the upper end of the lower sleeve; the upper surface of the support block is provided with a convex ridge for locating the plates, a section of the upper surface of the support ridge is convexly circular and is made of manganese steel alloy materials. The invention discloses a novel location support device for hot stamping plates so as to effectively reduce the heat loss of the plates during the hot stamping process, to increase the location precision of the plates, to ensure the processing precision and to increase quality of the products.

Description

technical field [0001] The invention relates to sheet material hot stamping forming technology, in particular to a positioning support device for sheet material hot stamping forming. [0002] Background technique [0003] The sheet metal hot stamping forming technology refers to the technology of heating the sheet metal and then stamping it with a die to obtain the product. It is mostly used in the preparation of automobile panels. [0004] In the existing sheet metal hot stamping forming technology (especially the hot stamping forming of automobile panels), the sheet metal is placed directly on the lower mold after heating, and the punch is used to align the cavity of the lower mold from above to punch down, forcing the sheet metal It deforms and enters between the cavity of the lower mold and the punch, and punches out a concave shape that matches the punch on the sheet. In this prior art, too fast heat loss is a problem that needs to be avoided as far as possible in she...

AI Technical Summary

Problems solved by technology

In this prior art, too fast heat loss is a problem that needs to be avoided as far as possible in sheet metal hot stamping forming technology, but it is a difficult problem to solve. How to reduce the heat loss in the process of sheet metal from the heating furnace to the mold is also studied by domestic and foreign scholars. hot spots, but so far there is no practical way to effectively control heat loss in actual processing

Excessive loss of heat will lead to defects such as increased processing difficulty and reduced processing accuracy
