Description
Technical field
The present invention relates to a kind of hydraulic balanced extruders.
Background technique
In the molding production of certain viscous materials, with there is a kind of descaling extrusion press.Its main component is a barrel and one
A extruding disk being hydraulically operated, barrel lower end are equipped with porous mould.Porous mould is to wait slabs, and disk is equal by pitch of holes
Mode be evenly distributed with the identical through-hole of multiple diameters.When operation, first material is placed in barrel, hydraulic coupling is then borrowed to make to squeeze disk
Other than material extruding cellular mould.Since in extrusion process, barrel is fixed, material tube inner wall just applies the material being in contact with it
The reason of frictional resistance, material itself has in addition viscosity and multiple-hole die dish structure, causes material each by porous mould
The discharging speed in hole is extremely uneven, and the speed closer to the hole at center, discharging is faster.This extremely non-uniform situation of discharging,
The production efficiency of rear process is seriously affected.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of hydraulic balanced extruder, and barrel can be by height
It is moved in the speed for squeezing disk to the direction of extrusion, so that the difference of the discharging speed between each hole of porous mould of uniform thickness be made to control
In smaller range, the production efficiency of process after raising.
The technical solution adopted by the present invention to solve the technical problems is: designed hydraulic balanced extruder includes porous
Mould seat, squeezes disk, left axle watt, bush seat, barrel, hydraulic cylinder, rack, axle bush covers, decelerating motor, gear, the right side at porous mould
Bearing shell and rack gear, porous mould seat, hydraulic cylinder, bush seat and decelerating motor are mounted on the rack, and the motor of decelerating motor is to hand over
Variable-frequency motor is flowed, left axle watt and right axle watt constitute sliding bearing, and bush seat and axle bush covers constitute split plain bearing seat, porous
Mould seat is cylindrical body, and porous mould is equal slabs, and it is identical that disk by the equal mode of pitch of holes has been evenly distributed with multiple diameters
Through-hole, porous mould are set to the top of porous mould seat and one, porous mould and porous mould seat are made with porous mould seat
Be clearance fit with barrel, squeeze disk be connected in hydraulic cylinder piston rod end and with barrel clearance fit, barrel and left axle watt
And the sliding bearing clearance fit that right axle watt is constituted, barrel both ends outside are equipped with boss, which is bolted with rack gear, tooth
Wheel is installed on the output shaft of decelerating motor and is engaged with rack.
Decelerating motor described in the technical program, retarder can be cycloidal-pin gear speed reducer.
The working principle of the invention is: when barrel relatively squeeze disk quickly move to the direction of extrusion when, material tube inner wall pair and
The frictional force that its material contacted generates just becomes the tractive force to material, and because of viscosity effect, makes the portion far from material tube inner wall
Position is also influenced by the tractive force, and the position closer apart from material tube inner wall is bigger by being influenced.Influence bigger, raising discharging
The effect of speed is stronger.In this manner it is possible to cut down the non-uniform situation of above-mentioned discharging, make the difference control of discharging speed between each hole
System is in lesser range.It should be noted that on the bigger circumference of radius, the quantity in hole is more on porous mould, to make each
The discharging speed in hole is identical, the more materials of the biggish circumferential location of radius circumferential location needs more lesser than radius, but due to
Viscosity effect, though barrel and extruding disk make synchronized movement in the same direction, and do not accomplish.When work, adjusted by electric-control system
The a-c cycle of power supply adjusts the output revolving speed of decelerating motor, and the barrel for driving rack-and-pinion relatively squeezes disk quickly to squeezing
Direction movement is pressed, to controlling the difference of discharging speed between each hole in lesser range.
The beneficial effects of the present invention are: relatively squeezing disk by barrel when work and quickly being moved to the direction of extrusion, make uniform thickness
Each hole of porous mould between discharging speed difference control in smaller range, improve the production efficiency of rear process.
Detailed description of the invention

Specific embodiment
Find out from Fig. 1 and Fig. 2, the hydraulic balanced extruder of the embodiment of the present invention includes porous mould seat 1, porous mould
2, disk 3, left axle watt 4, bush seat 5, barrel 6, hydraulic cylinder 7, rack 8, axle bush covers 9, decelerating motor 10, gear 11, right axle are squeezed
Watts 12 and rack gear 13.Porous mould 2 is equal slabs, and it is identical logical that disk by the equal mode of pitch of holes has been evenly distributed with multiple diameters
Hole.Porous mould seat 1, hydraulic cylinder 7, bush seat 5 and decelerating motor 10 are mounted in rack 8.The motor of decelerating motor 10 is to hand over
Variable-frequency motor is flowed, the retarder of decelerating motor 10 is cycloidal-pin gear speed reducer.Left axle watt 4 and right axle watt 12 constitute sliding bearing,
Bush seat 5 and axle bush covers 9 constitute split plain bearing seat.Porous mould seat 1 is cylindrical body, and porous mould 2 is set to multiple-hole die
Simultaneously one, porous mould 2 and porous mould seat 1 and barrel 6 is made as clearance fit with porous mould seat 1 in the top of disk seat 1.It squeezes
Platen 3 be connected in the piston rod end of hydraulic cylinder 7 and with 6 clearance fit of barrel.Barrel 6 and left axle watt 4 and right axle watt 12 are constituted
Sliding bearing be clearance fit, boss is equipped with outside 6 both ends of barrel, which is bolted with rack gear 13.Gear 11 is pacified
It is engaged on output shaft loaded on decelerating motor 10 and with rack gear 13.When work, frequency of supply is adjusted by electric-control system to adjust
The output revolving speed of decelerating motor 10, the barrel 6 for driving 11 rack gear 13 of gear relatively squeeze the faster speed of disk 3 and transport to the direction of extrusion
It is dynamic.In this way, the inner wall of barrel 6 is just become the tractive force to material to the frictional force that the material being in contact with it generates, and because viscous
Effect is spent, the inner wall position far from barrel 6 is made also to will receive the influence of the tractive force, the remoter position of the inner wall apart from barrel 6
It is smaller by being influenced.Bigger position is influenced, both closer to the inner wall position of barrel 6, the effect for improving discharging speed is got over
By force.In this manner it is possible to cut down the non-uniform situation of above-mentioned discharging, control the difference of discharging speed between each hole in lesser range
It is interior.To control the difference of discharging speed between each hole in lesser range.
