Abstract
The utility model relates to a fixed dummy block device for an aluminum profile, and the fixed dummy block device is a safety protection device of an extrusion shaft. According to the fixed dummy block device, a clamping pad is arranged between a fastening nut and a fixed rod and is a metal elastic component, and thus, an elastic structure in the fixing process of the device can be added. As the dummy block is fixed on the extrusion shaft and can move forward and backward along the extrusion shaft, the required separation and transportation time for a movable dummy block is saved, and the non-operation time is shortened; and a fixed dummy block is formed into a cone, and the metal backflow can be avoided after the cone is slightly expanded, so that a journal sticking accident is avoided, and the production efficiency can be improved.
Description
Technical field
The utility model relates to the extrusion axis safety guard, especially a kind of fixed dummy block device for aluminium section material.
Background technology
At present, for fear of extrusion axis too early wearing and tearing and damage, in the extrusion process of aluminium section bar, mostly adopt movable dummy block to push, between extrusion axis and dummy block, without any connector, after extruding ended, extrusion axis stopped.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, move on to lower of defective material separating scissors both separately dummy block deliver to the feeder front end through carrying in dress again, carry by feeder the extruder center sent into again, pushed in recipient by extrusion axis together with hot blank at last and push.For the continuity that circulates, generally to use simultaneously 2-3 movable dummy block sheet.This shows, the connecting gear of movable dummy block separates in dress with defective material be very complicated.Simultaneously, the movable dummy block sheet is difficult to accomplish carry out smoothly in separation and course of conveying, is easy to occur full axle fault, affects the extrusion process automatic circulating operation, and production efficiency is difficult to improve.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of device easily that dummy block is fixed on extrusion axis and changes.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of fixed dummy block device for aluminium section material, 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 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, the cloudy spiral shell that the center of other end processes with screw thread was connected one Dragon Boat Festival because of fixed pole therefore; Fixed bar is arranged in the through hole of fixed axis, one end is decided dummy block with week and is connected, the other end is with the fixed press cushion device that just forms the utility model after tightening up nut and tightening up and recommend, and described tightening up between nut and fixed bar is provided with mat, and described mat is metallic elastic spare.
The beneficial effect main manifestations of a kind of fixed dummy block device for aluminium section material of the utility model is: can advance or retreat with extrusion axis because dummy block is fixed on extrusion axis, save required separation and the time of delivery of movable dummy block, shorten the non-working time; Fixation extrusion pad is made cone, expands a little to avoid metal to flow backwards, and has stopped the seize accident, can enhance productivity.
Description of drawings
Fig. 1 is the structural representation of the utility model fixed dummy block device for aluminium section material.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model specific embodiment is described:
With reference to Fig. 1, the utility model fixed dummy block device for aluminium section material comprises and tightens up nut 1, extrusion axis 2, fixed bar 3 and fixation extrusion pad 4, extrusion axis 2 is processed into central through hole, fixed bar 3 is processed into two ends and has the stock that connects the positioning support state cylinder that has with pin thread, centre that two external diameters match with extrusion axis 2 endoporus, and the external diameter on the positioning support face of cylinder, two of fixed bar 3 centres and the endoporus of extrusion axis 2 are slidably matched; The fixation extrusion pad outer surface is processed into has two cones that screw with circular hole, and the end face that diameter is larger 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 arranged in the through hole of fixed axis 2, an end was with after fixation extrusion pad 4 is threaded, and the other end tightens up with tightening up nut 1, and described tightening up between nut and fixed bar is provided with mat, and described mat is metallic elastic spare.
In extrusion process, but the external diameter of fixation extrusion pad 4 swell tens roads under the extruding force effect, make it with recipient in interporal lacuna reduce, avoid metal to flow backwards, fundamentally stopped seize accident in 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 due to dummy block 4 is fixed on extrusion axis 2, fixation extrusion pad 4 can advance or retreat with extrusion axis 2, except the generation of having stopped the seize accident, compare with the use movable 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.
The above has done detailed description to the utility model preferred embodiment by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from the utility model aim.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
