Abstract
The invention discloses a novel diameter-adjustable fixed dummy block for an aluminum section extrusion press, which relates to the technical field of use of fixed dummy blocks for nonferrous metal heat extruders. A dummy block main body of the fixed dummy block is fixedly arranged on a mandril of the extrusion press through internal threads; a top block of the fixed dump block is arranged at an inner hole of the dummy block main body and is spliced with the dummy block main body through a first sliding block; the back side of the top block is screwed by nuts; key grooves are arranged on the nuts and the end surface of the top block and are fixed by keys and screws so as to prevent the top block from falling off during extrusion; the dummy block main body is positioned with the dummy block through a pin for bringing convenience for assembly and disassembly; the inclined plane of the first sliding block is matched with a second sliding block; and the tail end of the second sliding block is connected with the upper end and the lower end of the dummy block main body through adjustable nuts. A gap between the end surface of the top block and the main body can be regulated so that no restriction exists between the swelling coefficient of the main body and the kinds of alloy; the dummy block can be generally used, thus the specifications of the dummy block are reduced, thus the cost is saved; work procedures for replacing the dummy block is reduced, thus the production time is shortened; and the labor intensity of workers is reduced.
Description
Technical field:
The present invention relates to non-ferrous metal heat extruder fixation extrusion pad operation technique field, but a kind of aluminium section material extruder path transfer fixation extrusion pad.
Background technology:
Along with the progress of extrusion technique, fixation extrusion pad is used in and is domesticly used widely, and fixation extrusion pad is compared with original the sort of split dummy block, is a very big technological progress.
But in use run into a common question at present, same dummy block is when producing the aluminium alloy of the different trades mark, because the extruding force difference that different alloys is required, and the coefficient that swells of fixation extrusion pad changes along with the variation of extruding force, so when producing such as need change alloy designations, dummy block that can only the corresponding size of commutation, waste man-hour and manpower, and at high temperature operation is very inconvenient.
Summary of the invention:
But the purpose of this invention is to provide a kind of aluminium section material extruder path transfer fixation extrusion pad, it is by regulating the gap between top pad end face and the main body, and it doesn't matter for the trade mark of coefficient and alloy to guarantee to swell main body, and dummy block can be general, and reduce the specification of dummy block, saved cost; Reduce to change the operation of dummy block, saved production man-hour; Reduce working strength of workers.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises dummy block main body, top pad, nut, key, screw, pin, first slide block, adjustable nut and second slide block, the dummy block main body is fixed on the extruder push rod by internal thread, the top pad is arranged on the endoporus place of dummy block main body, and by first slide block and the grafting of dummy block main body, and top pad reverse side is by nut screwing clamping, have keyway at nut and top pad end face, fixed by key and screw, prevent that the top pad comes off when extruding; By finger setting, be convenient to installation and removal between dummy block main body and top pad; The inclined-plane of first slide block matches with second slide block, and the end of second slide block is connected with the two ends up and down of dummy block main body by adjustable nut.
Described first slide block and second slip front are provided with 45 ° inclined-plane, and first slide block and second slide block match by this inclined-plane.
Operation principle of the present invention is: when dummy block is worked, by first slide block and second slide block dummy block main body and top pad are matched, when needing to regulate the gap between dummy block main body and the top pad, regulate second slide block by regulating adjustable nut, the inclined-plane of second slide block matches with the inclined-plane of first slide block, promote first slide block, thereby promote the top pad, the dummy block rank size that expands is to the utmost point pushed, and extruding returns to life size by the dummy block main body after finishing.
The present invention is by regulating the gap between top pad end face and the main body, and it doesn't matter for the trade mark of coefficient and alloy to guarantee to swell main body, and dummy block can be general, and reduce the specification of dummy block, saved cost; Reduce to change the operation of dummy block, saved production man-hour; Reduce working strength of workers.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
With reference to Fig. 1, this specific embodiment is by the following technical solutions: it comprises dummy block main body 1, top pad 2, nut 3, key 4, screw 5, pin 6, first slide block 7, adjustable nut 9 and second slide block 10, dummy block main body 1 is fixed on the extruder push rod by internal thread 11, top pad 2 is arranged on the endoporus place of dummy block main body 1, and by first slide block 7 and 1 grafting of dummy block main body, and top pad 2 reverse side are tightened by nut 3, have keyway at nut 3 and top pad end face, fixing by key 4 and screw 5, prevent that top pad 2 comes off when extruding; Dummy block main body 1 and 2 on top pad pass through pin 6 location, are convenient to installation and removal; The inclined-plane of first slide block 7 matches with second slide block 10, and the end of second slide block 10 is connected with the two ends up and down of dummy block main body 1 by adjustable nut 9.
Described first slide block 7 and second slide block, 10 front ends are provided with 45 ° inclined-plane, and first slide block 7 and second slide block 10 match by this inclined-plane.
The operation principle of this specific embodiment is: when dummy block is worked, by first slide block 7 and second slide block 10 dummy block main body 1 and top pad 2 are matched, when needing to regulate the gap between dummy block main body 1 and the top pad 2, regulate second slide block 10 by regulating adjustable nut 9, the inclined-plane of second slide block 10 matches with the inclined-plane of first slide block 7, promote first slide block 7, thereby promote top pad 2, the dummy block rank size that expands is to the utmost point pushed, and extruding finishes the back and returns to life size by dummy block main body 1.
This specific embodiment is by regulating the gap between top pad end face and the main body, and it doesn't matter for the trade mark of coefficient and alloy to guarantee to swell main body, and dummy block can be general, and reduce the specification of dummy block, saved cost; Reduce to change the operation of dummy block, saved production man-hour; Reduce working strength of workers.
