Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
With reference to Fig. 4, the utility model improves the structure of existing cutting off tool, make its structure mainly comprises and cut off contact surface 3, intermediate incline 4, surface of subsidence 5, cutoff edge line 6, and devise the structure of split type upper cutter block 1, lower cutter block 2, thus also had improvement more in the past in the selection of material.As shown in Figure 4, cutter of the present utility model is that two ends are large, and it is irregularly shaped that centre has that one " neck " connect, and is similar to " work " font haply, is applicable to the coupling of automobile steel shape.Describe specific features and the Material selec-tion thereof of each structure above-mentioned below in detail.
First, in the selection of material, the high stamping press required by super-high strength steel cuts off, must select suitable mould and cutter material.Die matrix needs higher rigidity and toughness to avoid losing efficacy.Cutting off tool in mould needs higher hardness, recommends hardness at 60 ~ 65HRC.
When the tensile strength of steel is not less than 1000Mpa, cutting off tool should heat treatment, and material suggestion is 1.2379 or high performance mold materials, such as powder metallurgy (PM) material.When the tensile strength of steel is less than 1000Mpa, recommendation coating is to reduce the wearing and tearing of cutter.
Because die-cut material is martensite high intensity cold continuous-milling steel plate, yield strength 950 ~ 1200Mpa, tensile strength is not less than 1180Mpa.According to the above analysis, cutting off tool material selection powder metallurgy (PM) material V4E, and do not use coating.
As shown in Figure 1 and Figure 4, cut off contact surface 3 for cutting of steel material parts, its position is consistent with the front traditional cutting off tool of adjustment, and except middle part keeps original width dimensions to be except 10mm, other width dimensions is 2mm.Cutting off its edge of contact surface 3 is cutoff edge line 6.Other contact surface integral sinking original except the cut-out contact surface 3 newly determined are about about 5mm, form the surface of subsidence 5 shown in Fig. 1.The height of surface of subsidence 5 lower than cut-out contact surface 3, and is connected by intermediate incline 4 with between cut-out contact surface 3, and the intermediate incline 4 that the cut-out contact surface 3 after adjustment is about 135 degree with surface of subsidence 5 by inclination angle is connected, as shown in Figure 2.
Through said structure adjustment, when making to cut off, the contact area of cutter and part significantly reduces, and minimizing amplitude reaches 87.5%.Therefore, the demand to flush shear force is reduced.
On the other hand, consider that traditional cross cutting breaking structure is global design, and the cutting off tool of super-high strength steel part adopts high performance mold materials usually, as powder metallurgy (PM) material, its material cost is higher, this just result in the maintenance of cutter and replacement cost very high.Meanwhile, cutter is safeguarded frequently, will drastically influence the production efficiency of product, so be necessary to carry out Split type structure design to cutting off tool, improves the maintenance efficiency of cutter, reduces the maintenance cost of cutter.
Therefore, as shown in Figure 3, original unitary mould is divided into top and the bottom by the utility model, and namely cutting off tool comprises upper cutter block 1 and lower cutter block 2.Upper cutter block 1 and the separable replacement of lower cutter block 2, above-mentioned cut-out contact surface 3, intermediate incline 4, surface of subsidence 5, cutoff edge line 6 are all positioned at upper cutter block 1.The lower surface of upper cutter block 1 is connected with lower cutter block 2, and lower cutter block 2 is block firmware.Upper cutter block 1 materials'use V4E or other like powder metallurgy (PM) materials, lower cutter block 2 materials'use mould steel cr12mov or similar trade mark material, upper and lower two parts combine by the mode using bolt and alignment pin to combine.
The advantage of this upper cutter block of the utility model 1, lower cutter block 2 is, if cutter has had wearing and tearing through using for a long time, then only needs to replace upper cutter block 1, and lower cutter block 2 can Reusability for a long time.On the other hand, the volume of the integral type cutter that the volume due to upper cutter block 1 is more traditional is little, therefore upper cutter block 1 entirety can be adopted the metal of high strength more, such as V4E, and can't increase too much cost.
In sum, the beneficial effects of the utility model have:
1. meet the die-cut requirement of tensile strength more than the high-strength material part of 1000Mpa.
2. by the optimal design to conventional tool structure, improve cutter life (from 10,000 original jig frequencies, rising to 30,000 jig frequencies), reduce cutter maintenance cost, material cost reduces by 75%, and improves production efficiency and cutter changing speed.
