Abstract
The utility model discloses burr shears, belonging to the auxiliary shearing equipment which is matched with an edge trimmer. The utility model comprises cutter blades (1), wedge blocks (2), barrates (4) and rotary shafts (8), the rotary shafts (8) which are arranged in parallel are respectively provided with one barrate (4). The cutter blades (1) are installed in axial grooves and fixed through the wedge blocks (2), and the axial grooves are arranged on the circumferential surfaces of the barrates (4). Two steel spring plates (3) which are in circular arc surface protrusion are respectively installed between two contiguous cutter blades (1) on the barrates (4), and the height of the protrusion is higher than the height of the circumference on which the edge part of the cutter blade (1) is positioned. The shears can eliminate the blocking phenomenon which frequently appears when the burr shears in the prior art is used for cutting sheet band edge cutting, and satisfies the requirement that a machine set produces products with various specifications.
Description
The utility model relates to a kind of scrap cutter, and specifically a kind of scrap cutter that has flexible clamping and conveying device belongs to the auxiliary shearing equipment that cooperates bead cutter to use.
In the prior art, adopt two kinds of processing modes usually in its side cut of back that the band steel is cut edge: general thin strip is curled with crimping machine, and thicker just need adopt the broken limit of scrap cutter.But one the production specification of unit covers strip and thick band usually, and the belt steel thickness scope reaches 1.2～6.5mm.In this case, not only uneconomical as while configure volumes limit machine and scrap cutter, and usually because the place restriction can't realize it at all.Disposing a crimping machine and be with powerlessly to thick, is impracticable.And scrap cutter is when handling thickness less than the side cut of 2mm, the phenomenon of blocking in chute of cutting edge usually takes place again, its reason is: the side cut poor rigidity of thin steel band, when shearing, be in tensioned state, interval twice shearing then is in no restrained condition, the very easily resilience after shearing so cut edge, thus crooked so that stop up in chute.
The purpose of this utility model provides a kind of scrap cutter that has flexible clamping and conveying device, is used to shear the clogging that occurs when strip is cut edge to eliminate it, satisfies the needs of unit production plurality of specifications product.
The purpose of this utility model realizes by following measure.
A kind of scrap cutter has blade, voussoir, rotary drum and power transmission shaft, on two power transmission shafts that be arranged in parallel a rotary drum is installed respectively, and blade is installed in the axial groove that the rotary drum circumferential surface offers, and fixes by voussoir.Two-phase is faced a steel spring plate that is the arc surface projection respectively is installed between the blade on the rotary drum, and its height of projection is higher than blade blade place circumference height.
One end of steel spring plate is fixed on by voussoir in the axial groove of rotary drum, and the other end is by being bolted to drum surface.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Accompanying drawing is the structural representation of the utility model scrap cutter.
As shown in the figure, the utility model scrap cutter mainly is made up of blade 1, voussoir 2, steel spring plate 3, rotary drum 4 and power transmission shaft 8.One rotary drum 4 respectively is installed on two power transmission shafts that be arranged in parallel 8, and blade 1 is installed in the axial groove that rotary drum 4 circumferential surfaces offer, and is fixing by voussoir 2.Two-phase is faced a steel spring plate 3 that is the arc surface projection respectively is installed between the blade 1 on the rotary drum 4, and the one end is fixed on by voussoir 2 in the axial groove of rotary drum 4, and the other end is fixed on rotary drum 4 surfaces by bolt 7.The height of steel spring plate 3 projectioies is higher than blade 1 blade place circumference height.
During work, steel band through chute 5 guiding outputs cuts edge 6, at first be clamped between the steel spring plate 3 of a pair of projection on the rotary drum 4 about being installed on respectively, along with the rotation head side cut 6 of rotary drum 4 is constantly cut off, and follow-up side cut 6 by a pair of steel spring plate 3 clampings all the time.
The advantage that the utility model compared with prior art has is: being installed in up and down turns to A pair of on the drum consists of flexible clamping and conveying device to steel spring plate, and it is restrained that side cut is in all the time State has usually occurred when having eliminated scrap cutter of the prior art for the side cut of shearing strip Clogging has satisfied the needs of unit production plurality of specifications product. And simple in structure, Easy to implement.
Claims (2)
1. scrap cutter, have blade, voussoir, rotary drum and power transmission shaft, on two power transmission shafts that be arranged in parallel a rotary drum is installed respectively, blade is installed in the axial groove that the rotary drum circumferential surface offers, fix by voussoir, it is characterized in that: rotary drum (4) is gone up two-phase and is faced a steel spring plate (3) that is the arc surface projection respectively is installed between the blade (1), and its height of projection is higher than blade (1) blade place circumference height.
2. scrap cutter according to claim 1 is characterized in that: an end of described steel spring plate (3) is fixed in the axial groove of rotary drum (4) by voussoir (2), and the other end is fixed on rotary drum (4) surface by bolt (7).
