A kind of angle bar back chipping back-off machine
The present invention relates to a kind of angle bar process equipment, specifically a kind of angle bar back chipping back-off machine.
At building or machinery industry, angle steel or angle bar are added to man-hour, in order to guarantee that main material angle bar sectionalizing joint (angle steel/iron and angle cleat/iron) is adjacent to and glosss over a fault, in Tower processing, need main material or joint angle bar to take back-off or back chipping operation.
Prior art adopts planer or milling machine to process conventionally, but planer exists the shortcoming of inefficiency, and milling machine exists the shortcoming that cost is high, simultaneously in reality processing, no matter be planing tool or milling cutter, only have a cutting edge on a blade, blade material utilization rate is low.When back-off operation changes back chipping operation into, often need more allowing blade replacement, not only caused production efficiency low, and easily cause blade to lose.In addition, add man-hour on milling machine, existing angle bar back-off blade is plane milling blade, and the angle that plane milling blade processes is right angle, and the intensity at right angle is not as good as fillet, and the intensity of angle bar is weakened.Finally, blade temperature after working long hours raises, blade strength declines, and easily occurs the problem of tipping.
summary of the invention:
For solving the problems of the prior art, the present invention discloses a kind of angle bar back chipping back-off machine with back-off blade and back chipping blade integrated knife sheet.This back chipping back-off facility are high for blade material utilization rate, the advantage that production efficiency is high and cost is low.
Above-mentioned technical problem can adopt following technical scheme to solve, a kind of angle bar back chipping back-off machine, comprise body, drive unit, fixture, topping machanism and heat sink, wherein drive unit is arranged on body, described topping machanism comprises the blade holder being fixedly connected on drive unit and is clamped in the shaping blades in blade holder, on described shaping blades, both have back-off blade, also had back chipping blade.On shaping blades, have two kinds of blades simultaneously, solved the problem of blade material waste, and reduced the more time of allowing blade replacement and the probability of blade loss, improved productivity ratio, reduced production cost.
Described shaping blades is strip, and its one end is the back chipping blade of convex curve shape, and the other end is the back-off blade of sag vertical curve shape.
The cutting edge shape of described back-off blade is inside recessed semi-circular shape, and is positioned at the side with the relative one end of back chipping blade.The back-off blade of semicircle indent can shovel out the corner of rounded shapes, is beneficial to the intensity that keeps angle bar.
On described shaping blades, also offer screw fixing hole.
Described blade holder is a square iron block, and described shaping blades is screwed in blade holder.
Described drive unit is hydraulic cylinder.For need of production, drive unit can be also motor, cylinder or other driving arrangement.
Described heat sink comprises the water tank that is fixed on described hydraulic cylinder top, and water tank is connected with a water pipe, and the lower end of water pipe is connected with dropper, and the delivery port of described dropper is fixed on shaping blades top.
The delivery port of described dropper is fixed on 5 ~ 10cm place, shaping blades top.Under water droplet during blade work in bucket, to workspace, can take away heat, blade be heated up and be unlikely to too fast, extend the service life of blade
Described fixture is a clamp, and it is the groove of 90 ° that the two clamping faces middle parts at this grip finger place are processed with angle.
Advantage of the present invention: simple in structure, easy and simple to handle, production efficiency is high, blade material can be utilized effectively, and production cost is low.Meanwhile, at work, the water in bucket continues blade surface cooling with siphon principle, and blade face keeps suitable temperature always, reduces the probability that blade cutting edge crumbles, and extends the working life of blade, guarantees constant product quality simultaneously.Two kinds of cutting edges are integrated into the utilization rate that can improve material on same blade, are convenient to the processing of blade, can avoid blade to lose simultaneously, accelerate job schedule.

the specific embodiment:
According to Fig. 1, Fig. 2, angle bar back chipping back-off machine, comprising: body 1, hydraulic cylinder 2, clamp 3, and hydraulic cylinder 2 is fixed on body 1 top, and hydraulic cylinder 2 is integrated with body 1, and clamp 3 is fixed on the platform in body 1 the place ahead.Hydraulic cylinder 2 tops are fixed with water tank 4, water tank 4 is connected with a water pipe 5, and the lower end of water pipe 5 is connected with dropper 6, and hydraulic cylinder 2 front ends are fixed with blade holder 7, in described blade holder 7, clamping has shaping blades 8, the delivery port of described dropper 6 to be fixed on shaping blades 85 ~ 10cm places, top.
According to Fig. 3, shaping blades 8 is back-off, back chipping one blade, back-off blade 9 and back chipping blade 10 are separately positioned on the two ends of shaping blades 8, back-off adds man-hour shaping blades and 8 is laterally clamped in blade holder 7,9 machine-shapings of back-off blade are semicircular cutting edge, during clean-up machining, shaping blades 8 is longitudinally clamped in blade holder 7, and 10 machine-shapings of back chipping blade are right angle cutting edge, and shaping blades 8 middle parts have screw fixing hole 11.
Described blade holder 7 consists of square iron block, and shaping blades 8 is screwed onto in blade holder 7.
It is the groove of 90 ° that two clamping faces middle parts, clamp 3 jaw place are processed with angle, and angle bar both sides straight flange is stuck in groove, and clamp 3 clamps angle bar.
The foregoing is only preferred embodiment of the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, should belong to the scope of protection of the invention.
