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, being added to angle steel or angle bar man-hour, in order to ensure that main material angle bar sectionalizing joint (angle steel/iron and angle cleat/iron) is adjacent to and glosss over a fault, needing in Tower processing to take back-off or back chipping operation to main material or joint angle bar.
Prior art adopts planer or milling machine to process usually, but planer exists the shortcoming of inefficiency, and milling machine exists the high shortcoming of cost, simultaneously in reality processing, no matter be planing tool or milling cutter, a blade only has a cutting edge, blade material utilization rate is low.When back-off operation changes back chipping operation into, often need more allowing blade replacement, not only cause production efficiency low, and easily cause blade to lose.In addition, milling machine adds man-hour, 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 after working long hours temperature raise, blade strength decline, easily there is 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 high and advantage that cost is low of production efficiency.
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 be fixedly connected with on the drive means and the shaping blades be clamped in blade holder, described shaping blades both has back-off blade, also has back chipping blade.Shaping blades has two kinds of blades simultaneously, solve the problem of blade material waste, and decrease the time of more allowing blade replacement and the probability of blade loss, improve productivity ratio, reduce production cost.
Described shaping blades is strip, and its one end is the back chipping blade of convex curved 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 the semi-circular shape be inwardly recessed, and is positioned at the side with back chipping blade opposite side.The back-off blade of semicircle indent can shovel out the corner of rounded shapes, is beneficial to the intensity keeping angle bar.
Described shaping blades also offers 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 also can be motor, cylinder or other driving arrangement.
Described heat sink comprises the water tank being 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 above shaping blades.
The delivery port of described dropper is fixed on 5 ~ 10cm place above shaping blades.To workspace under water droplet during blade work in bucket, can heat be taken away, blade be heated up and is unlikely to too fast, extend the service life of blade
Described fixture is a clamp, is processed with the groove that angle is 90 ° in the middle part of two clamping faces at this grip finger place.
Advantage of the present invention: structure is simple, and easy and simple to handle, production efficiency is high, and 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, ensures constant product quality simultaneously.Two kinds of cutting edges are integrated into the utilization rate that same blade can improve material, are convenient to the processing of blade, blade can be avoided to lose simultaneously, accelerate job schedule.

Detailed description of the invention:
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 and body 1 are integrated, and clamp 3 is fixed on the platform in body 1 front.Hydraulic cylinder 2 top is 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 end is fixed with blade holder 7, described blade holder 7 is clamped with shaping blades 8, and the delivery port of described dropper 6 is fixed on 5 ~ 10cm place above shaping blades 8.
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 8 and is laterally clamped in blade holder 7, back-off blade 9 machine-shaping is semicircular cutting edge, during clean-up machining, shaping blades 8 is longitudinally clamped in blade holder 7, and back chipping blade 10 machine-shaping is right angle cutting edge, has screw fixing hole 11 in the middle part of shaping blades 8.
Described blade holder 7 is made up of square iron block, and shaping blades 8 is screwed onto in blade holder 7.
Be processed with the groove that angle is 90 ° in the middle part of clamp 3 jaw place two clamping face, in a groove, angle bar clamps angle bar both sides straight flange card by clamp 3.
The foregoing is only preferred embodiment of the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
