Description
?
Technical field
The present invention relates to a kind of cut-out mould, specifically be meant a kind of I-steel knife edge die.
Background technology
The ventilation channel plate of motor use at present is to adopt I-steel to cut off through plate shearing machine to process, and its section burr is many, and distortion is big, and I-steel contacts out-of-flatness with punching during welding, causes the rotor core inclination easily.
Summary of the invention
The purpose of this invention is to provide a kind of I-steel knife edge die, many to solve the burr that exists when present I-steel cuts off, be out of shape big technical problem.
The technical solution adopted for the present invention to solve the technical problems is: the I-steel knife edge die comprises die holder, fixing mould bases on die holder; It is characterized in that: described mould bases becomes the U type, and accumbency is fixed on the die holder, and opening forward; Fixing fixed die in the mould bases opening, the fixed die end face is concordant with the mould bases end face, is provided with " protruding " font movable mold in the front of fixed die; The bottom of movable mold is provided with support spring, and spring is sitting in the spring cavity that is provided with on the die holder, the fixing U-shaped cover plate at the top of mould bases; The fixed dam in mould bases body the place ahead of mould bases opening both sides; The A/F of U-shaped cover plate is less than the width of mould bases opening, and in the mould bases opening, stretch out through the cover plate opening by the top of movable mold with the following shutoff of the shoulder of fixed die and movable mold for the baffle plate through U-shaped cover plate and mould bases the place ahead; Movable mold can move up and down in mould bases, and an I-steel passage runs through movable mold, fixed die and mould bases rear mould bases body.
Described spring cavity is provided with the adjustment screw in its bottom, and the spring that the adjustment screw is passed in die holder and the spring cavity by the die holder bottom offsets.
Described I-steel knife edge die, corresponding I-steel passage is provided with support at the mould bases rear, and the upper surface of support is concordant with the passage bottom of I-steel passage, and slidably I-steel block is set on the support.
Block on the said support, itself and I-steel passage are not on same the straight line, and the side of its side and I-steel passage is tangent.
The invention has the beneficial effects as follows, make simply, with low cost, simple to operate, guarantee the section quality.

Among the figure, 1, die holder, 2, mould bases, 3, fixed die, 4, movable mold, 5, cover plate, 6, spring, 7, baffle plate, 8, the adjustment screw, 9, support, 10, the I-steel block, 11, the I-steel passage.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 1, the I-steel knife edge die comprises die holder 1, fixing mould bases 2 on die holder, and mould bases becomes the U type, and accumbency is fixed on the die holder 1, and opening is forward.
As shown in Figure 4, fixing fixed die 3 in the mould bases opening, fixed die 3 end faces are concordant with mould bases 2 end faces, are provided with movable mold 4 in the front of fixed die 3.
As shown in Figure 1, movable mold 4 is " protruding " font, and the bottom of movable mold is provided with support spring 6.
As shown in Figure 1, the fixing U-shaped cover plate 5 at the top of mould bases, fixed form adopts bolt, and fixed dam 7 in mould bases body the place ahead of mould bases opening both sides, and the A/F of U-shaped cover plate is less than the width of mould bases opening.
Like Fig. 1 and shown in Figure 4, in the mould bases opening, stretch out through the cover plate opening by the top of movable mold with the following shutoff of shoulder of fixed die 3 and movable mold 4 for the baffle plate 7 through U-shaped cover plate 5 and mould bases the place ahead, and movable mold can move up and down in mould bases.
As shown in Figure 4, an I-steel passage 11 runs through movable mold 4, fixed die 3 and mould bases 2 rear mould bases bodies.
Like Fig. 3 and shown in Figure 4; The bottom of spring is provided with adjustment screw 8; The spring 6 that adjustment screw 8 is passed in die holder and the spring cavity by die holder 1 bottom offsets, and spring 6 is sitting in the spring cavity that is provided with on the die holder, and this adjustment screw 8 can carry out the position adjustment according to the size of spring 6 tensile forces.
After making I-steel pass mould, effectively supported, like Fig. 1, shown in Figure 2, corresponding I-steel passage 11 is provided with support 9 at mould bases 2 rears, and the upper surface of support 9 is concordant with the passage bottom of I-steel passage 11.
Shearing length for convenient control I-steel like Fig. 1, shown in Figure 2, is provided with slidably I-steel block 10 on the support 9.
During assembling, I-steel knife edge die fixed die 3 is fixed by bolts on the mould bases 2, and end face is concordant with the mould bases end face.Movable mold 4 processing backs, can freely move up and down in mould bases 2 after the assembling, and certain blade clearance is arranged in mould bases with cover plate 5, baffle plate 7, bolts assemblies.Spring 6 end faces contact with movable mold 4, bottom surface and adjustment screw 8 close-fittings, and spring can be done stable linear telescopic in the time of can guaranteeing stamping-out.
The present invention suitably regulates the stroke of slider of punch in use, and the adjustment die location makes the end face of movable mold 4 align with die shank, and die holder 1 is fixed by bolts on the punch press backing plate.According to shearing length adjustment block 10 positions, the I-steel that cuts off when guaranteeing stamping-out can free-falling, and as shown in Figure 2, block 10 is not on same the straight line with I-steel passage 11, and the side of its side and I-steel passage 11 is tangent.The I-steel passage 11 of I-steel from movable mold 4 fronts inserted, pass fixed die 3 backs and align with block 10 sides, slider of punch is descending, and die shank contacts with movable mold 4, and 4 descending cooperations with fixed die 3 of movable mold are cut off I-steel.Slider of punch is up, and movable mold 4 is the position of backhaul before the stamping-out under the effect of spring.Continue to insert I-steel, the I-steel of insertion ejects the I-steel that cuts off from fixed die 3, repeats above action and continues stamping-out.
