Detailed Description

The invention will be further described with reference to specific examples, but the scope of protection of the invention is not limited thereto:

example (b): as shown in fig. 1, 2, 3 and 4, a high-precision cutting device is specifically composed of a hydraulic cylinder 1, a positioning guide pillar assembly 2, a cutting upper clamp assembly 3, a machine base 4, a cutting lower clamp assembly 5 and a cutting lower clamp assembly translation mechanism 6. Wherein the hydraulic cylinder 1, the positioning guide pillar component 2 and the cutting lower clamp component translation mechanism 6 are fixed on the machine base 4; the upper cutting clamp assembly 3 is fixed on the positioning guide pillar assembly 2; the cutting lower clamp assembly 5 is fixed right above the cutting lower clamp assembly translation mechanism 6; 3 tons of Tox hydraulic cylinders are selected as cutting power of the hydraulic cylinders, and BSHM20-250-M10-N10-SC5 guide shafts of MISUMI company are selected as positioning guide post components.

As shown in fig. 5 and 6, the cutting upper clamp assembly 3 is composed of a spring I7, a cutting upper clamp fixing block 8, a cutting guide shaft 9, a cutting upper die head 10 and a pressing block 11; after the spring I7 is connected with the pressing block 11, the pressing block is placed inside the upper cutting clamp fixing block 8; the cutting guide shaft 9 and the cutting upper die head 10 are fixed below the cutting upper clamp fixing block 8;

as shown in fig. 7 and 8, the cutting lower clamp assembly 5 is composed of a cutting lower die 12, a guide sleeve 13, a workpiece positioning shaft 14, a spring II15 and a cutting lower clamp fixing block 16; the cutting lower die head 12 and the guide sleeve 13 are fixed inside the cutting lower clamp fixing block 16, and the guide sleeve 13 is matched with the cutting guide shaft 9 for use; the workpiece positioning shaft 14 and the spring II15 are fixed on the cutting die head 12 and used for positioning the workpiece.

As shown in fig. 9, the cutting lower clamp assembly translation mechanism 6 is composed of a cylinder 17, a cutting lower clamp fixing seat 18, a cutting waste collecting box 19, a guide rail 20 and a translation mechanism base 21; the cylinder 17 and the guide rail 20 are fixed above the translation mechanism base 21; the cutting lower clamp fixing seat 18 is fixed on the guide rail 20; the cutting waste collecting box 19 is installed inside the cutting lower clamp fixing seat 18 and used for collecting cutting waste.

The utility model discloses during the use, at first the manual work is put into the frock with the work piece that needs cut. Then the cylinder is pressed downwards, the guide pillar is inserted into the guide sleeve (the guide pillar ensures the positioning precision), and the dislocation of the cutting mechanism and the tool is prevented. The hold-down mechanism contacts the parts firstly in the descending process, and the deviation in the cutting process is prevented from influencing the cutting effect (such as burrs, flanging, indentation and the like) by the aid of the pressure of the spring. After the metal plate edges of the parts contacted by the cutting heads are cut, the upper clamp limiting cylinders on the two sides continue to move downwards to finish cutting in the process of continuing descending. The design of moving back of cutting head both sides (L1, L2 size) can prevent to cut the panel beating side band after accomplishing, and L size is the demand size, cuts down the chamfer theta of die head and is for getting into the location for the convenience work piece, designs out the waste material entry A that cuts after moving back the sword simultaneously, prevents that the smear metal putty from influencing the effect of cutting next time. The size of the workpiece before cutting is X, the size after cutting is X-S, the pressing cylinder ascends after cutting is completed, and the cutting head is separated from the part to complete cutting processing of one workpiece.

Wherein, fig. 6 and 8 show the details of cutting the upper and lower dies, and the sheet metal edge is prevented from being cut after the sizes of the design of the cutter withdrawing design L1 and L2 are designed. The upper and lower cutting dies are made of Cr12MoV material, and the hardness treatment is more than HRC 58. Figure 10 shows the part size change before and after cutting. By the utility model, the cutting size X-S is set, and the process requirement is satisfied.
