A reverse short-stroke aluminum extrusion machine top dead material mechanism

Abstract

The invention discloses a top dead material mechanism of a reverse short-stroke aluminum the extrusion machine, which comprises a piston bracket, a cleaning extrusion rod is arranged on the piston bracket, and the cleaning extrusion rod is connected to a curved surface through a connecting part. One end of the arm, the middle part of the crank arm is hinged to the mounting plate fixed on the piston bracket, and the other end of the crank arm is hinged to one end of the driving part, and the other end of the driving part is connected to the piston bracket through a hinge on the shelf. The above-mentioned reverse short-stroke aluminum extrusion machine top dead material mechanism rotates the crank arm through the driving component to make the cleaning extrusion rod reach the working position, and then the main plunger pushes the cleaning extrusion rod to push the unmoved spindle out of the extrusion cylinder. , not only shortens the length of the extruder; but also has high production efficiency, reduces the labor intensity of workers, and facilitates installation and maintenance.

Description

A reverse short-stroke aluminum extrusion machine top dead material mechanism

technical field

The present invention relates to a kind of reverse extrusion machine, relate in particular to a kind of reverse short-stroke aluminum the extrusion machine top dead material mechanism.

Background technique

[0002] Extruders are divided into two different types: metal extruders and plastic extruders (also known as plastic extruders, extruders, extruders), and are used in different industrial fields. The existing horizontal reverse profile extrusion press adopts a front and rear double extrusion rod structure, which makes the overall length of the extruder longer in terms of structural composition, thus affecting the production efficiency; in addition, there are difficulties in maintenance and installation. , inconvenient operation and other defects.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a kind of reverse short-stroke aluminum the extrusion machine top dead material mechanism, it has the characteristics of reasonable structure, high production efficiency, and easy installation and maintenance, to solve the reverse short stroke in the prior art Problems with aluminum extrusion presses.

For reaching this purpose, the present invention adopts the following technical scheme:

A kind of reverse short-stroke aluminum extrusion press top dead material mechanism, it comprises piston bracket, and described piston bracket is provided with cleaning extrusion rod, and described cleaning extrusion rod connects crank arm by connecting member one end of the crank arm, the middle part of the crank arm is hinged on the mounting plate fixed on the piston bracket, and the other end of the crank arm is hinged to one end of the drive part, and the other end of the drive part is connected to the piston bracket through a hinge superior.

[0006] In particular, the end of the cleaning squeeze rod is provided with a cleaning squeeze pad.

[0007] In particular, the piston bracket is provided with a rod seat, the cleaning extrusion rod is fixed in the rod seat through the gland, and the crank arm is connected to the rod seat.

The beneficial effect of the present invention is, compared with the prior art, described reverse short-stroke aluminum extrusion press top dead material mechanism makes cleaning extrusion rod reach working position by rotating crank arm by driving part, then by main, The plunger pushes the cleaning extrusion rod to push the unmoved spindle out of the extrusion cylinder, which not only shortens the length of the extruder, but also has high production efficiency, reduces the labor intensity of workers, and facilitates installation and maintenance.

Description of drawings

Fig. 1 is the structural representation of the reverse short-stroke aluminum the extrusion machine top dead material mechanism provided by specific embodiment 1 of the present invention.

detailed description

[0010] The technical scheme of the present invention is further described below in conjunction with the accompanying drawings and through specific embodiments.

schematic structural representation of the reverse short-stroke aluminum the extrusion machine top dead material mechanism provided by the specific embodiment of the present invention 1.

In the present embodiment, a kind of reverse short-stroke aluminum extrusion press top dead material mechanism comprises piston bracket 1 and described piston bracket 1 is provided with rod seat 2, and in described rod seat 2, through pressure The cover 4 is fixed with a cleaning squeezing rod 3, an end of the cleaning squeezing rod 3 is installed with a cleaning squeezing pad 8, and the rod seat 2 is connected to one end of the crank arm 5. The middle part of the crank arm 5 is hinged on the mounting plate 6 fixed on the piston bracket 1, and the other end of the crank arm 5 is hinged to one end of the driving oil cylinder 7, and the other end of the driving oil cylinder 7 is connected to the driving oil cylinder 7 through a hinge. on the piston carrier I.

When top dead material, first by driving oil cylinder 7 to rotate crank arm 5 to make cleaning extruding rod to 3 reach working position, namely cleaning extruding rod 3 and the centerline of the inner hole of extruding cylinder 9 are on the same straight line, then Push the cleaning extrusion rod 3 by the main plunger to push the unsqueezable spindle out of the extrusion cylinder 9.

The above embodiment has just set forth the basic principle and characteristic of the present invention, the present invention is not limited by the above-mentioned example, without departing from the spirit and scope of the present invention, the present invention also has various changes and changes, these changes and Variations fall within the scope of the claimed invention. The claimed scope of the present invention is defined by the appended claims and their equivalents.
