Abstract
The utility model relates to a slide block-type shearing machine for waste steel. A machine body is welded into integration, and a transmission mechanism is a belt and gear reduction transmission mechanism. The head end of a main shaft is provided with a crank shaft and the tail end is connected with the transmission mechanism, and a rectangular slide block which is sheathed on the crank shaft is slid in a square guideway. A left and a right limit stops of the square guideway and a bottom board form an integral type, and the outer sides of the limit stops are provided with stiffening ribs. An upper cutter body which is connected with the slide block moves in parallel up and down, and the rate is from 20 to 32 times per minute. The table surface of an unloading table which is positioned on the inner side of the lower cutter body is an inclined surface. The utility model has the advantages of compact structure, high rigidity, light weight, low cost and good shearing performance, and is especially suitable for medium and small martensitic steel plants and material salvage departments to shear waste steel.
Description
The utility model relates to a kind of slide block type scrap shearing machine, belongs to metal material electric shears tool, is mainly used in the usefulness that malleable iron factory, steel-casting foundry and metal goods and materials department of recovery shear waste and old steel.
Malleable iron, cast steel industry and goods and materials department of recovery need become particle with waste and old steel cutting, so that transportation and smelting again.Domestic above-mentioned industry is handled steel scrap and is all adopted gas cutting more than 80% at present.Gas cutting steel scrap not only efficient is low, and labour intensity is big, and the cost height brings environmental pollution, and metal charge that can scaling loss 5% during gas cutting, causes sizable waste.Domestic have factory of a few family to produce the large-scale cutter of a kind of crocodile formula, though the work efficiency height, shearing force is big, avoids the waste of environmental pollution and metal charge, and volume is big, big energy-consuming, cost height, general middle-size and small-size malleable iron factory, and particularly numerous goods and materials recovery companies are difficult to bear.And the motion of its cam, connecting rod, rigidity is relatively poor; The movable edge of a knife rotates in fixed axis, and the each point shearing force does not wait, and is big near the edge of a knife position shearing force of fulcrum, and material is thick more, can only be far away more during shearing from fulcrum, and it is unreasonable therefore to shear force-bearing situation, shears power to fail to give full play to, and cutting performance is just good inadequately certainly.
The purpose of this utility model is to overcome deficiency of the prior art, provides that a kind of volume is little, in light weight, cost is low, good rigidly, during shearing stressed rationally, the slide block type scrap shearing machine that cutting performance is good.
The technical solution of the utility model is: the slide block type scrap shearing machine is made up of fuselage, motor, transmission mechanism, main shaft, head slide, cutter hub, discharging platform critical piece.Transmission mechanism is belt, gear reduction transmission mechanism.The main shaft head end is provided with bent axle, and tail end links to each other with transmission mechanism.Main shaft is a horizontal, by rolling bearing and sliding supported condition.The head slide is made of rectangular shaped slider and square guide rail, and rectangular shaped slider is sleeved on the bent axle.This project organization compactness, good rigidly, easy to process, precision guarantees easily.The monolateral gap of slide block and guide rail is 0.05～0.08mm, does not have during motion and rocks.The upper knife body that links to each other with slide block is done parallel reciprocating motion up and down, and the each point shearing force equates on the edge of a knife, and reliably guaranteed after the adjustment of edge of a knife gap up and down, cutting performance is good.The discharging platform table top that is positioned at the lower knife body inboard is the inclined plane, and the steel material after the shearing skids off automatically, shears in order to avoid pile up influence.
In the such scheme, fuselage is welded into integral body by steel plate, than cast type weight reduction, improves impact resistance again.Reduction gearing mechanism is the one-level belt, and the two-stage gear reduction can effectively satisfy the needs of gearratio, does not cause the volume of gear wheel excessive again.The high speed shaft that links to each other with big belt pulley is provided with flywheel, improves cutting performance.Bent axle becomes monoblock type with main shaft, the intensity height, and the eccentric throw of bent axle is 22～30mm, is fit to the stroke requirement of small-sized cutter.The left and right block of square guide rail becomes monoblock type with the guide rail base plate, and the left and right block outside is provided with reinforcement.This structure is more easy to process than triangular form guide rail or other pattern guide rail, and precision guarantees easily, and strength and stiffness are good.The upper knife body motion frequency is per minute 20～32 times, and the upper knife body edge of a knife becomes 6 °～12 ° with horizontal plane.
Adopt the slide block type scrap shearing machine volume of said structure little, in light weight, cost is low, and stressed rationally cutting performance is good, and power consumption is few, and production efficiency is higher.Complete machine weighs 1.4～1.6 tons, power 5.5kw, and shearing thickness is no more than 20mm, 4～5 tons of per tour shearing displacements.Being particularly suitable for middle-size and small-size malleable iron factory and goods and materials recovery company uses.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the transverse cross-sectional view of rectangular shaped slider and square guide rail.
As figure, fuselage 1 is welded into integral body by steel plate, and motor 2 is 5.5kw, and rotating speed 1440rpm, transmission speed reducer structure are one-level belt reducing gear 3, and two- stage gear reduction 6 and 7 is provided with flywheel 5 on the high speed shaft 4 that links to each other with big belt pulley.Main shaft 9 horizontal supportings are on rolling bearing 8 and sliding bearing 10.The head end of main shaft is a bent axle 13, and both are integral, and crankshaft eccentric is apart from 25mm.The rectangular shaped slider 12 that is sleeved on the bent axle by sliding sleeve 14 slides up and down in square guide rail 11, is provided with panel 19 between slide block both sides and the guide rail.20 one-tenth monoblock types of left and right guide rail block 18 and guide rail base plate of square guide rail, the left and right guide rail block outside is provided with arc reinforcement 21.The upper knife body 15 that links to each other with slide block is done parallel reciprocating motion up and down, and the edge of a knife becomes 10 ° with horizontal plane.Lower knife body 16 maintains static, and its inboard discharging platform table top 17 is the inclined plane, tilts 25 °.Present embodiment weighs 1.5 tons, cutting stroke 50mm, and below the shearing thickness 15mm, shearing frequency 28 times/minute.
