Abstract
The utility model relates to an extruding needle rotating device of an extruder, which consists of a motor and a transmission device. The motor is fixed on the upper portion of a slide block, a motor shaft is provided with a small bevel gear, the small bevel gear is meshed with a large bevel gear, a shaft of the large bevel gear is a worm shaft, the worm shaft is meshed with a worm gear, and the worm gear rotates through a mandrel driven by a spline. One end of the mandrel is in threaded connection with an extruding needle while the other end is connected with a piston rod of an extruding needle moving cylinder through a spherical gasket, and the extruding needle moving cylinder is mounted inside a plunger of a main cylinder. The extruding needle is guided through a copper sleeve and moves back and forth and rotates inside a hollow extruding shaft, thereby realizing rotation of the extruding needle. Rotation angles of the extruding needle can be digitally displayed through an encoder. Through rotation of the extruding needle, the problem that the pipe wall at the front end of an extruded pipe is thick in upper portion and thin in lower portion is resolved. In addition, the extruding needle rotating device of an extruder has the advantages of novel and simple structure, low cost, fine effect and the like, and then belongs to a novel extruding needle rotating device of an extruder integrating economical efficiency and practicality.
Description
Technical field
The utility model relates to a kind of extruder extruding pin whirligig, and this device is suitable for the extrusion process of boring a hole, and uses during extruding high accuracy tubing.
Background technology
When the perforation of extruder utilization at present extrusion process carries out the tubing extruding, the extruding pin can wear and tear when the extruding number of times is too much, because the extruding pin is in cantilever position, be subjected to the influence of gravity, it is less to make the extruding pin top wearing and tearing occur, wearing and tearing more situation in below is pushed so again and will be caused the pipe front end of extruding thick fickle condition down on the tube wall to occur, has reduced the geometric accuracy of extrude tubes.If what energy was regular will push the rotation that pin carries out specified angle, guarantee that wearing and tearing are consistent on the circumference, then can improve the geometric accuracy of extrude tubes.At existing problem in the above-mentioned prior art, a kind of novel extruder extruding of research and design pin whirligig, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel extruder extruding of research and design pin whirligig, thereby solves the inconsistent problem of tubing generation wall thickness that perforation extrude tubes technology is extruded of using.Extruder extruding pin whirligig described in the utility model is made up of motor and transmission device.Described motor is fixed on slide block top, and motor shaft is equipped with bevel pinion, bevel pinion and bevel gear wheel engagement, and the axle of bevel gear wheel is a worm shaft, worm shaft and worm gear engagement, worm gear rotates by the mandrel that spline drives.One end of mandrel is connected with the extruding pin by screw thread, and the other end is connected by the piston rod of ball ring with extruding pin movable cylinder, and extruding pin movable cylinder is installed in the plunger of master cylinder.The extruding pin is directed at by copper sheathing and seesaws in the hollow extrusion axis and rotate.
Extruder extruding pin whirligig described in the utility model, be on the extruder slide block, to be provided with the Worm-gear type whirligig, this covering device is contained on the slide block, motor reducer drives the worm screw rotation by bevel gear, the worm and wheel engagement drives the worm gear motion, and worm gear rotates by the mandrel that spline drives; Mandrel is realized by screw thread and is pushed being connected of pin, thus the rotation that realizes pushing pin; The anglec of rotation can realize that numeral shows by encoder.By the rotation of extruding pin, thick thin down situation on the tube wall appears in the tubing front end of having avoided extruding.
When adopting extruding pin extrude tubes, need accurately to locate the relative angle of extruding pin and mould, realize by rotation extruding pin.Realize being connected by ball ring between mandrel and the extruding pin movable cylinder plunger, have adaptation function, mandrel rotates, and does not rotate and push pin movable cylinder plunger rod.The extruding pin leads by bronze bushing, moves in the endoporus of extrusion axis, guaranteed the extruding pin to neutrality.
The utlity model has advantages such as novel structure, simple structure, cost be low, effective, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
