Embodiment Construction

[0014] Specific embodiments of the present invention are described in further detail below in conjunction with accompanying drawing:

[0015] In the mold changing device for multi-die stamping of sheet metal shown in the figure, its lower mold frame 1 is fixed on the press frame 13 , and its upper mold frame 10 is fixed on the press hammer 9 . Taking the center line 14 of the hammer 9 of the press as the axis, the lower mold frame 1 is fixed with lower molds 2 of multiple pairs of molds arranged in the circumferential direction. On the upper die frame 10, the upper die 5 of the plurality of pairs of molds corresponding to each lower die 2 arrangement positions is installed, and each upper die 5 is supported by a stage clip 4, and can move vertically in the upper die frame 10. A rotary mold changer 7 is arranged above each upper mold 5 in the upper mold frame 10, and the rotary mold changer 7 is installed on the fixed shaft 8 overlapping with the center line 14 of the press ham...

Abstract

The invention provides a mould changing method and device for multi-mould press working of a plate. The process is provided by arranging the up-down moulds mounted on the up-down mould frames on the circle with the press drive-hammer central line as axle, and by the selection of the mould changer and its cam rotated around the axle to the up-mould and transmission of the press force, completing mould-changing process for the plate in the same station. The device comprises an up-down mould, a rotary mould changer, and a cam, wherein the circular motion track corresponds to the arrangement position of the up-mould, the press force is transferred to the up-mould by the mould changer and the cam, and the up-mould and the down-mould are matched together. In the device, multiple corresponding press mould is fixed, which simplifies the structure and improves the working precision and stability.

Description

technical field [0001] The invention relates to a stamping process technology of multiple shapes at the same station of a plate, in particular to a die changing method and a die changing device for the stamping process of multiple dies of a plate. Background technique [0002] The method of punching and processing plates with multiple shapes at the same station is essentially a method of changing multiple molds for plates at the same station. The method can improve the processing precision of the sheet metal and shorten the processing cycle, thereby improving the automation degree of the sheet material processing industry and promoting the obvious growth of economic benefits. However, most of the devices currently on the market for realizing multi-die changing stamping processing are turret-type, pneumatic or hydraulic manipulator-driven die-changing stamping devices. Although the structures and transmission methods of these devices are different, thei...
