Abstract
The invention discloses a pull rod automatically rotating and adjusting mechanism for an extruder. The mechanism comprises at least one pull rod, wherein a pull rod adjusting cap is arranged on the pull rod, the pull rod adjusting cap is in threaded connection with the pull rod, and the pull rod adjusting cap is fixedly connected with worm wheels, the worm wheels are connected with a worm, and the worm is connected with a driving device. According to the invention, the driving device is used for rotating the worm to drive the worm wheels, the pull rod is driven by the worm wheels to adjust the cap to rotate, so that the function of adjusting the length of the pull rod is achieved, the structure can be used for optionally switching processes of fixed needle extrusion and follow-up needle extrusion, labor is reduced, and the implementation is automated; meanwhile, the production efficiency is effectively improved, and the installation and maintenance are convenient.
Description
Technical field
The present invention relates to a kind of extruder, relate in particular to a kind of extruder pull bar automatic rotation governor motion.
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 pull bar adjustment structure that applies to the horizontal profile extruder is all used manual adjustments, due to reasons in structure, makes its equipment when being fixed pin with the conversion of servo-actuated pin extrusion process, take larger manually, increased dead cycle time, thereby affected production efficiency; In addition, also exist the defects such as maintenance difficult in maintenance, difficult, operation inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of extruder pull bar automatic rotation governor motion, it has the advantages that to reduce manually, save time and be convenient to installation and maintenance, to solve in prior art when the extruder pull bar is regulated the problem existed.
For reaching this purpose, the present invention by the following technical solutions:
A kind of extruder pull bar automatic rotation governor motion, it comprises at least one pull bar, wherein, being provided with pull bar on described pull bar regulates and cap, described pull bar regulate and cap and pull bar between be threaded, and described pull bar is regulated and cap is fixedly connected with worm gear, and described worm gear is connected with worm screw, described worm screw connecting drive device.
Especially, described pull bar is set to two, these two pull bar parallel interval are arranged, be connected with moving crosshead between described two pull bars, and described two pull bars are regulated by pull bar and cap cap a cap b are arranged on moving crosshead, and described worm screw is fixed on moving crosshead by the worm screw holder.
Especially, described drive unit is hydraulic motor, and described hydraulic motor is installed on moving crosshead by the hydraulic motor holder.
Especially, described worm gear and pull bar are regulated also, between cap, the antirotation keys rod are set.
Beneficial effect of the present invention is, compared with prior art described extruder pull bar automatic rotation governor motion drives worm gear by the drive unit rotary worm, drive pull bar by worm gear and regulate also cap rotation, to reach the length adjustment effect to pull bar, this structure can be fixed the pin extruding and arbitrarily switch with servo-actuated pin extrusion process, not only reduce manually, implement automation; And effectively raise production efficiency, be convenient to installation and maintenance.
The accompanying drawing explanation
Fig. 1 is the profile of the extruder pull bar automatic rotation governor motion that provides of the specific embodiment of the invention 1;
Fig. 2 is the side view of the extruder pull bar automatic rotation governor motion that provides of the specific embodiment of the invention 1.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the profile of the extruder pull bar automatic rotation governor motion that provides of the specific embodiment of the invention 1; Fig. 2 is the side view of the extruder pull bar automatic rotation governor motion that provides of the specific embodiment of the invention 1.
In the present embodiment, a kind of extruder pull bar automatic rotation governor motion comprises the pull bar 1 that two parallel interval are arranged, be connected with moving crosshead 2 between described two pull bars 1, and described two pull bars 1 are regulated and cap 3 by pull bar, and cap 4a, and cap 4b is arranged on moving crosshead 2, described pull bar regulate and cap 3 and pull bar 1 between be threaded, and described pull bar is regulated and cap 3 is connected with worm gear 5, and the fitting key rod reaches anti-rotating function between the two, described worm gear 5 is connected with worm screw 6, described worm screw 6 is fixed on moving crosshead 2 by worm screw holder 7, head is connected on hydraulic motor 8, described hydraulic motor 8 is installed on moving crosshead 2 by hydraulic motor holder 9.
When needing the length of adjusting yoke 1, hydraulic motor 8 starts 6 rotations of drive worm screw, the worm gear 5 that rotarily drives of worm screw 6 rotates, worm gear 5 drives pull bar again and regulates also cap 3 rotations, thereby by pull bar regulate and cap 3 and pull bar 1 between helicitic texture, drive pull bar 1 and move, realize the automatic adjusting to pull bar length.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
