Abstract
The utility model relates to a fixed dummy block device for aluminium section materials. The utility model is a safety device for an extruding shaft. Since a dummy block fixed to the extruding shaft can move forwards or backwards with the extruding shaft, the time of separating and conveying the dummy block is saved, and free time is shortened. The fixed dummy block made into a cone can prevent metal from flowing back via slight expansion, the accident of winding the shaft is eliminated, and productive efficiency is increased.
Description
A kind of aluminium section bar fixed press cushion device, it is that safety guard is taken out in extruding.
At present, for fear of extrusion axis too early wearing and tearing and damage, in the extrusion process of aluminium section bar, mostly employing activity dummy block pushes, without any connector, after extruding ended, extrusion axis stopped between extrusion axis and the dummy block, recipient is opened one and is a bit larger tham the gap that dummy block adds defective material thickness, and dummy block and defective material are released from recipient.Extrusion axis returns original position, and recipient is opened required stroke once again.Main scissors shears off dummy block and defective material together from goods, fall into chute, moves on to defective material and separates to cut the two is separated.Dummy block is delivered to the feeder front end through conveying device again, carries the extruder center of sending into by feeder again, is taken out to push in the recipient by extruding with hot blank at last and pushes.For the continuity that circulates, generally to use 2-3 movable extruding pad simultaneously.This shows that the connecting gear of movable dummy block and defective material separator are very complicated.Simultaneously, movable extruding pad is difficult to accomplish carry out smoothly in separation and course of conveying, is easy to occur the seize fault, influences the automatic periodic duty of extrusion process, and production efficiency is difficult to improve.
In order to solve an above-mentioned difficult problem, the purpose of this utility model provides and a kind ofly is fixed on dummy block on the extrusion axis and changes device easily.
The purpose of this utility model is to realize like this, this device comprises extrusion axis, fixed bar, fixation extrusion pad and tightens up nut, extrusion axis is processed into central through hole, fixed bar is processed into two ends to have pin thread, centre and has the stock that the face of cylinder that endoporus matches is taken out in two external diameters and extruding, the outer surface of fixation extrusion pad is processed into cone, an end face processes the crescent sphere, and the center of other end processes and the fixed bar negative thread that one Dragon Boat Festival, screw thread was connected; Fixed bar is installed in the through hole of fixed axis, and an end is decided dummy block with week and is connected, and the other end just forms the fixed press cushion device that the utility model is recommended with tightening up after nut tightens up.
Again with structure of the present utility model, be described in detail as follows in conjunction with the accompanying drawings:
Fig. 1 is a structural representation of the present utility model.
By among Fig. 1 as can be seen, the utility model is formed by tightening up nut 1, extrusion axis 2, fixed bar 3 and fixation extrusion pad 4, extruding is taken out 2 and is processed into central through hole, fixed bar 3 is processed into two ends to have and connects the stock that has the positioning support face of cylinder that two external diameters match with extrusion axis 2 endoporus with pin thread, centre, and the external diameter on two positioning support faces of cylinder and pushing is taken out 2 endoporus and is slidingly matched in the middle of the fixed bar 3; The outer surface of fixation extrusion pad 4 is processed into has two cones that screw with circular hole, and the end face that diameter is bigger processes the crescent sphere, and the center of other end processes and the fixed bar negative thread that 3 one Dragon Boat Festival, screw thread was connected; After fixed bar 3 was installed in the through hole of fixed axis 2, an end was with after fixation extrusion pad 4 usefulness are threaded, and the other end tightens up with tightening up nut 1.
In extrusion process, the external diameter of fixation extrusion pad 4 big tens roads that under the extruding force effect, can rise, make it with recipient in interporal lacuna reduce, avoid metal to flow backwards, fundamentally stopped to embrace the uranium accident in the extrusion process, improved productivity ratio.After fixation extrusion pad 4 damages, can change easily, in order to avoid extrusion axis 2 is collided or weares and teares.
This device is owing to be fixed on dummy block 4 on the extrusion axis 2, fixation extrusion pad 4 can advance or retreats with extrusion axis 2, except that the generation of having stopped the seize accident, compare with use activity dummy block, also saved the conveying device of dummy block, shorten the non-working time of extruder, improved the reliability of the automatic operating of extruder, further improved production efficiency.
Claims (1)
1, a kind of aluminium section bar fixed press cushion device, it comprises that extruding is taken out, fixed bar, fixation extrusion pad and tighten up nut, it is characterized in that extrusion axis is processed into central through hole, fixed bar is processed into two ends and has the stock that pin thread, centre have the face of cylinder that two external diameters match with the extrusion axis endoporus, the outer surface of fixation extrusion pad is processed into cone, an end face processes the crescent sphere, and the center of other end processes and the fixed bar negative thread that one Dragon Boat Festival, screw thread was connected; Fixed bar is installed in the through hole of fixedly taking out, and an end is connected with fixation extrusion pad, and the other end tightens up with tightening up nut.
