Abstract
The utility model provides a cutting scissors blade for cutting angle steel with pressure. The provided cutting scissors blade for cutting angle steel is combined into an integral body by four convex blades and four concave blades; the convex blades and the concave blades can be exchanged when the centre points rotate 90 DEG every time. The utility model has the characteristics of simple structure, high utilizing rate, etc. Compared with the existing double-face single-blade cutting blade, the utilization rate of the utility model can be enhanced for 8 times; the consumed fund of enterprise cutting blade is just one third that of the original enterprise cutting blade.
Description
The utility model belongs to a kind of cutting edge that the pressure cut off angle steel is used.
The cutting edge that is used for the angle steel cut-out at present is according to shown in Figure 1, adopt two-sided single-blade cutting edge, promptly this cutting edge is made up of recessed sword (1) and protruding sword (2) respectively, and recessed sword and protruding sword be separately fixed at up and down and carry out work on the die holder, promptly scraps after recessed sword and protruding sword two-sided all used.Though this single-blade cutting edge is simple in structure, its utilization rate is very low, cause cutting edge consumption big, cut off the angle steel expense and improve.To shear 30,000 tons of steel enterprises year is example, adopts two-sided single-blade cutting edge year consumption about 180～200 pairs, and cutting edge consumes substantial contribution.
Goal of the invention of the present utility model provides a kind of angle steel simple in structure, that utilization rate is high to cut off and uses cutting edge based on the deficiency of above-mentioned two-sided single-blade cutting edge.
A kind of angle steel provided by the utility model to achieve the above object cuts off cutting edge, it is characterized in that this cutting edge is become one by four protruding swords and four recessed swords, be 90 ° of angles between protruding sword and the protruding sword and arrange, also be 90 ° of angles between recessed sword and the recessed sword and arrange, and protruding sword is adjacent with recessed sword.Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the schematic diagram of existing two-sided single-blade cutting edge;
The angle steel that Fig. 2 provides for the utility model cuts off the front view of cutting edge;
Fig. 3 is the A-A cross section view that cuts off cutting edge according to angle steel shown in Figure 2;
Fig. 4 is that the utility model is installed in the schematic diagram on upper bolster and the die shoe in use respectively.
The utility model cuts off cutting edge according to Fig. 2, angle steel shown in Figure 3, be made up of four protruding swords (3) and four recessed swords (4), and its central part is provided with locating hole (5), and this cutting edge is fixed in several fixing holes (6) on the die holder.Fixing hole (6) operated by rotary motion is at the corresponding site of every protruding sword, and is center symmetry mutually with the locating hole.The length of side L of each protruding sword equates that all the length of side R of each recessed sword also all equates.Be as the criterion with its central point O between protruding sword and the protruding sword and be mutually 90 °, be as the criterion with its central point O between same recessed sword and the recessed sword and also be mutually 90 °, length for protruding sword length of side L and recessed sword length of side R is decided on the angle steel label range that it cut off, be generally that R equals L or R is slightly larger than L, and R or L are greater than the length of side of angle steel.As being＜2.5 for the angle steel that is cut off
#～＜5
#Cut-out angle steel cutting edge in the scope, then its length of side is got L=52mm, and R=53mm gets final product.Between R or L, as long as it medium and small can reach the cut-out purpose greater than the angle steel length of side.
A kind of cut-out angle steel cutting edge provided by the utility model cuts off cutting edge (7) with two identical angle steel and is installed in respectively on upper bolster (8) and the die shoe (9) according to shown in Figure 4, and cutting edge and die holder are fastening by screw (10).Its working face of cutting edge that is fixed on the upper bolster is recessed sword, and its working face of cutting edge that is fixed on the die shoe is protruding sword.For the cutting edge on the upper bolster, just can change recessed sword with the every half-twist of its center positioning hole, treat four recessed swords two-sided all use to unload down to be installed in after scrapping use its protruding sword working face on the die shoe.In like manner,, just can change protruding sword with the every half-twist of its center positioning hole for the cutting edge on the die shoe, treat four protruding swords two-sided all use to unload down to be installed in after scrapping use its recessed sword working face on the upper bolster.
The utility model has simple in structure, utilization rate high according to the above-mentioned angle steel cutting blade of cutting scissors that content was provided. The used steel of the utility model are recessed sword and the protruding sword sum that is not enough to two-sided single-blade cutting edge, and its utilization rate is compared with two-sided single-blade cutting edge and can be improved 8 times. Shearing 30,000 tons of steel enterprises year as example, the angle steel cutting blade of cutting scissors that adopts the utility model to provide, Year's consumption only need 20～25 pairs and can meet the demands according to aforesaid, and cutting edge consumes every year can save substantial contribution.
Claims (3)
