Upper die component includes upper bolster, upper padding plate, train wheel bridge and upper de- plate, and lower mold assemblies include lower template, lower bolster and die shoe,
Wherein：The upper die component also includes being connected with train wheel bridge and the longitudinally perpendicular cutting edge for penetrating upper de- plate, the upper de- plate
On offer for cutting edge longitudinally through upper groove, and the lower surface of upper de- plate form in the horizontal direction it is vertical with upper groove
Upper workpiece location division, the longitudinal section of upper workpiece location division at right angles down, the horizontal right angled triangle of hypotenuse；Lower template it is upper
Surface forms the lower workpiece location division to match with the upper workpiece location division of upper de- plate in the horizontal direction, lower workpiece location division
The right angled triangle that longitudinal section is rectangular upward, hypotenuse is horizontal, upper workpiece location division is formed with lower workpiece location division in matched moulds
Position the rectangular piece location division of square tube workpiece；Also form and passed through for cutting edge and vertical with lower workpiece location division in lower template
Lower groove；The lower surface of the cutting edge is blade part, and the blade part has a nose part protruded down, and the nose part
The right angle end of position and upper workpiece location division is on same longitudinal straight line.
The utility model mould is designed using the location division of tilting, and making square tube, inclined formula positions in a mold, and
The blade part design nose part of cutting edge, makes nose part relative with the right angle position of tubing, first from the feed of right angle portion, profit during punching
Strength during punching is effectively decomposed with two right-angle sides, the stress of square tube is decomposed into along the equal direction in square tube surface, so as to keep away
Exempt from square tube surface to deform；Moreover, punching speed is fast, efficiency high, abrasion will not be produced, sparks are flying in all directions for nothing, to workshop condition
Pollution-free, otch is also more smooth attractive in appearance.
Brief description of the drawings：
Fig. 1 is the planar structure schematic diagram of the utility model mould；
Fig. 2 is the partial exploded view of the utility model mould.
Embodiment：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As shown in Figure 1 and Figure 2, described in the present embodiment it is a kind of square pipe cut-off die tool, it includes upper die component 1 and lower mould
Component 2, upper die component 1 include upper bolster 11, upper padding plate 12, train wheel bridge 13 and upper de- plate 14, and lower mold assemblies 2 include lower template
21st, lower bolster 22 and die shoe 23, wherein：The upper die component 1 also includes being connected and longitudinally perpendicular penetrating with train wheel bridge 13
The cutting edge 15 of upper de- plate 14, offer on the upper de- plate 14 for cutting edge 15 longitudinally through upper groove 141, and upper de- plate
14 lower surface forms the upper workpiece location division 142 vertical with upper groove 141 in the horizontal direction, upper workpiece location division 142
The right angled triangle that longitudinal section is rectangular down, hypotenuse is horizontal；The upper surface of lower template 21 forms in the horizontal direction to be taken off with upper
The lower workpiece location division 211 that the upper workpiece location division 142 of plate 14 matches, the rectangular court in longitudinal section of lower workpiece location division 211
Right angled triangle upper, hypotenuse is horizontal, upper workpiece location division 142 form positioning square tube in matched moulds with lower workpiece location division 211
The rectangular piece location division of workpiece 3；Also form and passed through for cutting edge 15 and vertical with lower workpiece location division 211 in lower template 21
Lower groove 212；The lower surface of the cutting edge 15 is blade part 151, and the blade part 151 has the nose part protruded down
152, and the right angle end of the position of the nose part 152 and upper workpiece location division 142 is on same longitudinal straight line.
When carrying out cutting off processing, first square tube workpiece 3 is made along being horizontally placed in the lower workpiece location division 211 of lower template 21
Each face of square tube is obliquely placed to coincide with the locating surface of two tiltings of lower workpiece location division 211；When the die is closed, upper mould
Lower de- plate 14 in component 1 is first inconsistent with the lower template 21 of lower mold assemblies 2, passes through the upper workpiece location division 142 of upper de- plate 14
The rectangular piece location division formed with the lower workpiece location division 211 of lower template 21 square tube is clamped into positioning；Then, upper die component 1
In cutting edge 15 continue to move downward, due to the nose part 152 of cutting edge 15 is downwardly projecting and alignment position be workpiece
One right angle end, therefore the nose part 152 of cutting edge 15 first enters knife from square tube right angle end, because the both sides at right angle end can be effectively
The pressure for the nose part that right angle end is subject to is decomposed, and the oblique blade of the both sides of nose part 152 is diagonally cut simultaneously after the incision of right angle end
Cut the two sides of square tube, direction of feed is almost with square tube plane parallel, therefore square tube is not in deformation in cutting-off process, is had
The quality of square tube cutting is ensure that to effect, and accelerates the efficiency of cut-out, the abrasion for reducing workpiece wastes.
Certainly, it is different according to the dimensions of square tube workpiece, it can correspondingly design the upper de- plate of different dimensions
14th, the size and specification of the workpiece location division in lower template 21, meanwhile, the position of the nose part 152 of cutting edge 15 can also be made
Adjusted design, it can thus take replacing with de- plate, lower template, the mode of cutting edge and adapt to different dimensions square tubes
Cutting off processing.
To sum up, the utility model mould is designed using the location division of tilting, makes square tube inclined formula positioning in a mold,
And the blade part in cutting edge designs nose part, make nose part relative with the right angle position of tubing, first enter from right angle portion during punching
Knife, strength during punching is effectively decomposed using two right-angle sides, the stress of square tube is decomposed into along the equal direction in square tube surface, from
And square tube surface is avoided to deform；Moreover, punching speed is fast, efficiency high, abrasion will not be produced, sparks are flying in all directions for nothing, to workshop
Environmental nonpollution, otch are also more smooth attractive in appearance.
