Abstract
The invention discloses a disc fixation extrusion pad assembly of an extruder. The disc fixation extrusion pad assembly is arranged on the front end of an extrusion rod, comprises an extrusion pad, and is characterized in that the end surface of the extrusion rod is provided with a fixation pad connection key, an extrusion pad fixation pad is positioned through the fixation pad connection key, and the extrusion pad is movably arranged on the end part of the extrusion pad fixation pad. Compared to the traditional design, the disc fixation extrusion pad assembly of the present invention has the following advantages that: the relative change is less, the modification cost is low, the structure is simple, the processing cost and the use cost are substantially reduced, and the time required for replacement repair is reduced, such that the production efficiency can be ensured so as to provide a good popularization value.
Description
Technical field
The present invention relates to the extruder technical field, relate to a kind of dish-shaped fixation extrusion pad that is used for extruder in particular.
Background technology
Along with improving constantly of extruder automatization level, as the crucial prerequisite of extruder fully automatic operation, the application of fixation extrusion pad is also increasingly extensive.At present, fixation extrusion pad generally adopts the expansion type combining structure.When this structure is utilized bracer front pressurized with the expansion central shoring greatly reaching sealing to the ingot-containing tube extrusion chamber, design is comparatively complicated and machining accuracy and installation accuracy all had very high requirement.And because each extruding; Bracer and expansion loop are directly all wanted repeated friction; So the wearing and tearing between the contact position are very big, the gap that wearing and tearing produce is also sneaked into assorted bits, the service life of reducing a whole set of dummy block greatly easily; Also strengthened the difficulty of dismounting when changing, serious even can cause a whole set of fixed press pad assembly to scrap.Therefore, the use cost of expansion type fixation extrusion pad is higher relatively.
Summary of the invention
The object of the invention is exactly provide for the deficiency that solves prior art a kind of not only simple and practical, and easy to maintenance, the dish-shaped fixed press pad assembly of the extruder that use cost is lower.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of dish-shaped fixed press pad assembly of extruder; Be installed on the pressure ram front end; Comprise dummy block, it is characterized in that the end face of said pressure ram is provided with the fixed bolster connecting key; The dummy block fixed bolster is by fixed bolster connecting key location, and dummy block is movably arranged on the end of dummy block fixed bolster.
As further specifying of such scheme: be provided with the pressure ram long bolt in the said pressure ram, the dummy block fixed bolster spins through the pressure ram long bolt and is fixed on the pressure ram.
Said dummy block end face adopts the design of dish-shaped indent, during pressurized end face from the center outward distending to reach sealing to the ingot-containing tube extrusion chamber.
Said pressure ram long bolt passes the pressure ram middle part and cooperates with the end face roof pressure of dummy block.
Be connected with the spline form between said dummy block and the dummy block fixed bolster.
The back of said dummy block is provided with protruding position; Protruding position is provided with spline; This spline is fixed by the dummy block hold-down nut; The middle part of dummy block fixed bolster is provided with and the concavo-convex through hole that cooperates in said protruding position, is provided with the spline interface in the through hole, and is fixing to prevent the spline displacement by the dummy block hold-down nut again after this spline screws and puts in place.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The used material that the present invention adopts has only about half of conventional expansion type fixed bolster, and the general replacing dummy block part that only needs, and use cost reduces greatly; Reduced repeated friction between each parts, each component wear is reduced, the life-span is longer; Connection between each parts is simpler, and difficulty of processing reduces greatly, and dummy block only need twist hold-down nut and just can directly screw out, and changes efficient and convenient, improves the operating efficiency when safeguarding greatly.

The specific embodiment
Like Fig. 1-shown in Figure 5, the dish-shaped fixed press pad assembly of a kind of extruder of the present invention is installed on pressure ram 5 front ends; Mainly form, be connected through pressure ram long bolt 6 between dummy block fixed bolster 2 and the pressure ram 5, by fixed bolster connecting key 4 location by dummy block 1, dummy block fixed bolster 2, dummy block hold-down nut 3; Adopt the spline connected mode between dummy block 1 and the dummy block fixed bolster 2; The back of dummy block is provided with protruding position, and protruding position is provided with spline 8, and the middle part of dummy block fixed bolster is provided with and the concavo-convex through hole that cooperates in said protruding position; Spline interface 7 is set in the through hole; Only need during installation that dummy block 1 splined end is aimed at dummy block fixed bolster 2 spline interfaces 7 and insert, rotate to the position that dummy block hold-down nut 3 can be installed, fixing the dummy block hold-down nut at last can accomplish.Dummy block 1 adopts dish-shaped concave inward structure 9, seals the ingot-containing tube extrusion chamber through the mode that external diameter behind the positive end face pressurized swells.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
