Abstract

The invention discloses a backward extrusion mechanism for horizontal profile extruders, which comprises an oil cylinder assembly, a backward extrusion stem and an extrusion die, wherein the oil cylinder assembly is arranged on a rack body, the backward extrusion stem is arranged on a front beam of the rack body, and the inner end of the backward extrusion stem is equipped with a backward extrusion stem seat; and the front end of the backward extrusion stem is provided with the extrusion die. The backward extrusion mechanism for horizontal profile extruders disclosed by the invention has the advantages that: through fixedly arranging the extrusion stem on a front beam and arranging the extrusion die at the front end of the extrusion stem, the direction of forward motion of an extrusion shaft and the metal flow direction are opposite, compared with the conventional forward extrusion structure, the backward extrusion mechanism bears small external frictional influence, deformation areas of a spindle focus on positions near the extrusion die, and metal flows uniformly, therefore, less extruded lock holes and residual extruded wastes are produced, and the structures and mechanical properties of extrusion products are relatively uniform; and under same conditions, the extrusion force required by the backward extrusion mechanism is less than that required by the forward extrusion structure.

Description

A kind of indirect extrusion machine structure that is used for horizontal section bar extruder
Technical field
The present invention relates to horizontal section bar extruder technology, relate in particular to a kind of indirect extrusion machine structure that is used for horizontal section bar extruder.
Background technology
Extruder is divided into metal extrusion press and two kinds of plastic extruders are dissimilar, and is applied in different industrial circles.The existing general employing forward extrusion mechanism that applies to horizontal section bar extruder; Suffered in the course of the work external friction influence is bigger; The deformed area of spindle flows inhomogeneous; It is surplus with pressure also can to produce certain extruding lockhole, thereby makes that the mechanical property of extruded product is relatively poor, thereby has influenced production efficient; In addition, also exist defectives such as installation difficult in maintenance, difficult, operation inconvenience.
Summary of the invention
To above defective, the purpose of this invention is to provide a kind of receive external friction influence little, push lockhole and press surplus less, the indirect extrusion machine structure that is used for horizontal section bar extruder that helps enhancing product performance, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of indirect extrusion machine structure that is used for horizontal section bar extruder; Comprise hydraulic cylinder assembly, reverse pressure ram, extrusion die; Hydraulic cylinder assembly is installed on the Rack Body, and said reverse pressure ram is installed on the front-axle beam position of Rack Body, and this reverse pressure ram the inner is furnished with reverse extruding pole socket; Said reverse pressure ram front end is installed extrusion die.
The beneficial effect that is used for the indirect extrusion machine structure of horizontal section bar extruder of the present invention is: through pressure ram is fixedly installed on front-axle beam; And mould is installed in the pressure ram front end, and promptly extrusion axis direction of advance and metal flow are in the opposite direction, compares existing forward extrusion structure; The suffered external friction of reverse extruding influences little; The deformed area of spindle concentrates near the mould and flows evenly, therefore pushes lockhole and presses surplus waste material less, and the tissue and the mechanical property of extruded product are more even; Under same case, the reverse required extruding force of extrusion structure will be lower than forward extrusion power.
Description of drawings
According to embodiment and accompanying drawing the present invention is done further explain below.
Fig. 1 is the said indirect extrusion machine structure sketch map that is used for horizontal section bar extruder of the embodiment of the invention.
Among the figure:
1, hydraulic cylinder assembly; 2, shifting formwork slide block; 3, Rack Body; 4, oppositely push pole socket; 5, reverse extruding circle; 6, reverse pressure ram; 7, extrusion die adapter sleeve; 8, extrusion die; 9, front-axle beam position.
The specific embodiment
As shown in Figure 1; The indirect extrusion machine structure that is used for horizontal section bar extruder of the present invention; Comprise hydraulic cylinder assembly 1, reverse pressure ram 6, extrusion die 8; Said hydraulic cylinder assembly 1 is installed on the Rack Body 3, and said reverse pressure ram 6 is installed on the front-axle beam position 9 of Rack Body 3, and said reverse pressure ram 6 the inners are furnished with reverse extruding pole socket 4 and the two junction reverse extruding circle 5 that is locked; Said reverse pressure ram 6 front ends are installed extrusion die 8 and the two socket place is provided with extrusion die adapter sleeve 7; Hydraulic cylinder assembly 1 one sides are provided with shifting formwork slide block 2.
