A kind of push-plate type chip area
Technical field
The present invention relates to wheel hub and manufacture field, be specifically related to a kind of push-plate type chip area.
Background technology
Wheel hub is the vitals that automotive wheel is connected with axle, need that turnery processing is carried out to blank in process of production and can produce a large amount of aluminium bits, lathe is provided with chip cleaner, aluminium bits are discharged, is transported to after appointed place centralized recovery sends into smelting furnace melting by chip area and reuses as raw material.
Existing chip area as shown in Figure 3 and Figure 4, comprise groove 1 and spaced arc push pedal 12 and pin 13, lever 13 is arranged in the middle part of the notch of groove 1, it is highly less than the height of push pedal 12, roller-way 20 is provided with bottom groove 1, roller-way 20 is placed with the main shaft 14 parallel with groove 1, main shaft 14 one end is connected with hydraulic cylinder 15, main shaft 14 upper surface is provided with the T-shaped connecting rod 16 with push pedal 12 quantity Matching, push pedal 12 middle and lower part is provided with connecting hole 18, lower end is provided with breach 19, main shaft 14 and roller-way 20 pass from breach 19, the vertical portion of T-shaped connecting rod 16 is upward through connecting hole 18, the length of horizontal part is greater than the length of connecting hole 18, the intrados of push pedal 12 is towards hydraulic cylinder 15 place end, aluminium bits fall into groove 1, the lower end of push pedal 12 by aluminium consider to be worth doing keep off, keep upright state, the piston rod of hydraulic cylinder 15 is retracted, push pedal 12 is pulled to move to direction, hydraulic cylinder 15 place with aluminium bits by main shaft 14, when push pedal 12 arrives lever 13 place, its upper end hinder by lever 13, its lower end is pulled tilting by main shaft 14, push pedal 12 is in faces upward the state of lying, when the piston rod of hydraulic cylinder 15 stretches out, push pedal 12 keeps facing upward the state of lying and moves backward, when its extrados hinder by lever 13 place at rear, its lower end is continued movement backward and is made push pedal 12 be reset to upright state, chip removal process is carried out and so forth.
The shortcoming of this chip area have following some:
One, aluminium bits are easily stuck by roller-way at bottom land, and fault rate is high, and roller-way is positioned at below main shaft, and are mixed with a large amount of cutting fluids from the aluminium bits that lathe is discharged, and the visual field is bad, and maintenance difficulty is large;
Two, push pedal and lever collide realization and face upward and lie, reset, and the two is all metal material, and the noise that collision produces is large;
Three, push pedal lower end is provided with breach and passes for main shaft and roller-way, and the aluminium bits falling within indentation, there cannot be got rid of, and define chip removal dead angle, chip removal weak effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of push-plate type chip area, can solve that existing chip area fault rate is high, maintenance difficulty is large, noise is large and the problem of chip removal weak effect.
The present invention is achieved through the following technical solutions:
A kind of push-plate type chip area, comprise groove, the push pedal of at least two block gaps settings, main shaft, top, described groove two side is respectively equipped with the rail groove parallel with groove, and described main shaft both sides are respectively equipped with running roller, and described running roller rolls and is connected to rail groove; Described main shaft one end and the first reciprocating drive unit transmission, described main shaft is also fixedly connected with the second reciprocating drive unit, is connected with between the second reciprocating drive unit and between adjacent push pedal in outermost one piece of push pedal respectively by link transmission; Described main shaft both sides are connected to axle, and described running roller is rotationally connected with axle, and described axle is also rotatably connected to axle sleeve, and described push pedal upper end is fixedly connected with montant, and described montant upper end is fixedly connected on axle sleeve outer wall; Described push pedal is rotationally connected with axle, and two sides is respectively towards the two ends of groove.
Described push pedal is provided with hole, is provided with the bar on connecting hole both sides in hole, bar is rotatably connected to bar cover, and interlinking lever end is fixedly connected on bar cover.
The cross section of described main shaft is triangle, on one of them angle.
Described first reciprocating drive unit and the second reciprocating drive unit are respectively hydraulic piston.
The present invention's advantage is compared with prior art:
One, main shaft both sides arrange running roller, roll and are connected in the rail groove arranging top, groove two side, and aluminium bits are not easy injection groove and cause running roller stuck, effectively reduce fault rate, and are convenient to maintenance;
Two, there is no the place of hard collision in chip removal process, do not produce noise;
Three, there is not breach in push pedal lower end, all aluminium bits falling into groove can be pushed away away simultaneously, there is not chip removal dead angle;
Four, main shaft cross section is triangle, on one of them angle, makes main shaft upper end form two inclined-planes, does not have aluminium bits and gathers, do not need manually to sweep, and reduces the possibility of aluminium bits injection groove further, reduces fault rate.

Detailed description of the invention
A kind of push-plate type chip area as depicted in figs. 1 and 2, comprise the push pedal 2 of groove 1, at least two block gap setting, main shaft 4, the cross section of described main shaft 4 is triangle, on one of them angle; Described main shaft 4 both sides are connected to axle 3, described axle 3 outer end is connected with running roller 9, and described axle 3 is also rotatably connected to axle sleeve, and described push pedal 2 upper end is fixedly connected with montant, described montant upper end is fixedly connected on axle sleeve outer wall, makes push pedal 2 two sides respectively towards the two ends of groove 1; Top, described groove 1 two side is respectively equipped with the rail groove 8 parallel with groove 1, and described running roller 9 rolls and is connected to rail groove 8; Described main shaft 4 one end and the first hydraulic piston 5 transmission, described main shaft 4 is also fixedly connected with the second hydraulic piston 7, described push pedal 2 is provided with hole, the bar 10 on connecting hole both sides is provided with in hole, bar 10 is rotatably connected to bar cover 11, outermost one piece of push pedal 2 be connected to respectively by end winding support connecting rod 6 that bar overlaps 11 between the second hydraulic piston 7 and between adjacent push pedal 2 and be in transmission connection and be connected.
