Method and device for cutting fragile sheet work piece

Abstract

The invention relates to a method for cutting a fragile sheet work piece. The method comprises the following steps: a clamp mould group clamps the two side surfaces of the fragile sheet work piece along a preset cutting line on a finished product area that the fragile sheet work piece wants to be reserved, then a cutting mould aligns with the edge of the preset cutting line along the clamp mould group to carry out a stroke or an up and down clamp cutting toward the fragile sheet work piece to cut the fragile sheet work piece, and the cutting of the fragile sheet work piece is finished. A device for cutting the fragile sheet work piece comprises the clamp mould group and the cutting mould, wherein the clamp mould group comprises a movable type clamp mould and a fixed type clamp mould; the fixed type clamp mould is fixed on a punching machine; the movable type clamp mould is actuated by a clamping actuation mechanism; the cutting mould is actuated by a cutting actuation mechanism. The cutting is quick, the production cost is low, no air pollution problem exists, the water source use can be reduced, and the water source pollution can be reduced.

Description

technical field [0001] The invention relates to a cutting method and device for fragile workpieces. A clamping mold group is used to clamp the two sides of fragile workpieces along a predetermined cutting line, and to clamp the fragile workpieces. On the reserved finished product area, use the cutting mold to align the outer edge of the predetermined cutting line along the clamping mold group, and perform a stroke or clip up and down on the fragile work object to cut the fragile work object Objects, a method and device for cutting fragile work objects. Background technique [0002] In construction engineering, it is common to paste cut and surface-treated stone slabs on the wall to decorate the wall or ground of the building. Most of these stone slabs are taken from natural raw stones after many times of cutting, and then It is made by surface treatment; or the above-mentioned stone slabs are manufactured by man-made methods, and a large area of ​​stone slabs is firstly pro...

AI Technical Summary

Problems solved by technology

[0004] 1. The cutting stroke is extremely long, and the stroke feed is very slow, so the cutting operation is very time-consuming

[0005] 2. When cutting, it is necessary to use a lot of water resources for cooling

[0006] 3. When milling, sawing and grinding, a large amount of dust will be generated, which will seriously pollute the air environment and damage the health of operators

[0007] 4. Due to the extremely lengthy cutting time, the manufacturing cost is relatively increased

[0008] 5. Because the wire saw, milling cutter, and grinding wheel have a long machining profile on the slate, that is, the cutting distance is very long, so the tool consumption is extremely large

[0012] 1. In the above method, when the movable biting die 50a and the fixed biting die 50b bite the stone plate 52 up and down slowly, the material of the stone plate 52 is extremely hard and brittle, and it is not easy to form a straight Therefore, the profile of the bitten stone slab 52 is extremely uneven, and its fragmentation shape cannot be predicted, so a jagged irregular profile is often produced

[0013] 2. Regardless of whether it is too thick or too thin, this method of biting slowly from top to bottom is not applicable

Because it cannot be bitten off when it is too thick; it is easy to be irregular and brittle when it is too thin

[0014] 3. Due to the high failure rate in manufacturing, it is not widely used
