Background technology:

Ring Rolling Machine comes out decades; Be widely used in each class bearing inner and outer ring, flange, gear ring and train rim etc. and produce per year in tens million of tons the production in enormous quantities of various rings, Ring Rolling Machine mainly contains two big types of vertical Ring Rolling Machine and horizontal Ring Rolling Machines, and the former uses middle-size and small-size ring; The latter is used for large ring; Horizontal Ring Rolling Machine complex structure, cost is high, and the price of a horizontal Ring Rolling Machine often is tens times even tens of times of common vertical Ring Rolling Machine.The ring diameter of the vertical Ring Rolling Machine processing of all size in the past generally all is no more than 400 millimeters; Along with the development of technology and the growth of ring demand; The vertical Ring Rolling Machine that manufactures and designs now can rolling diameter reaches the ring of 1200mm; Because its price only is the remnant of horizontal Ring Rolling Machine price, and receives the welcome of most of medium-sized and small enterprises.

The rolling ring process of vertical Ring Rolling Machine; Main roll milling wheel is in the decline process while rotating, and incision is enclosed within the outer garden of ring base on the core roller, and borrows the tangent direction friction power drive ring base of contact surface to rotate together with the core roller; Main roll milling wheel and core roller constitute a pair roller; Along with the decline of main roll milling wheel, the ring reduced thickness, inside and outside garden enlarges accomplishes the ring process of rolling over when reaching the requirement size.It should be noted Vertical Ring Rolling machine ring blank is set in the core roll stand (and horizontal ring rolling machine ring blank is lying on the bench), all by weight of ring blanks core roller bear, the main rolling wheel In the cut surface of the ring blank is formed tangential friction ring blank and the core must be greater than the lower bearing rollers and the moment of inertia and other rotational resistance, or not only with the main rolling wheel swivel blanks, but pressed into the outer surface of the ring blank the formation of pits, so that the ring rolling process can not be, especially for a large outside garden large eccentric ring blanks with turn more laborious, more prominent contradictions, which is restricted Vertical Ring Rolling Machine upsizing and ring blanks weight One of the important reasons.

Summary of the invention:

The utility model is aimed at the development of large vertical ring rolling machine of the above difficulties, design a suitable core vertical ring rolling machine roller rotation device, so that the core roll rolling round by the main belt through passive ring blanks turn, can become drive rotation of the main wheel and the ring rolling preform prior to contact, actively driven by rotating the core roll ring blanks first rotated at an appropriate speed, the main rolling wheel has rotated the ring blanks cut surface, the tangential frictional force without moment of inertia to overcome their resistance, etc., but as the relay to run the same, then sideband turn, edge rolling.

The technical scheme of the utility model: be installed in lower support outside oil motor or motor; After slowing down, pass through machine driving secondary (like gear, sprocket wheel or belt wheel); Drive is installed in the interior bolster of lower support, rotates together with the core roller that tightly is inserted in the bolster, makes the core roller possess the function of active rotation.When adopting oil motor, export branch's oil circuit by the pumping plant of vertical Ring Rolling Machine, through pressure-reducing valve and adjustable pipe rupture valve to oil motor; The output shaft of oil motor links to each other with input shaft of speed reducer; The output shaft of decelerator links with bolster through mono-directional overrun clutch and by machine driving is secondary, after red-hot ring base is enclosed within on the static core roller, when the rolling ring is initial; Pumping plant pressure oil gets into oil motor through pressure-reducing valve and adjustable pipe rupture valve; Overcome rotary inertia and other rotary resistance of ring base, core roller and bolster, make the core roller, and borrow its frictional force to drive the ring base and rotated fork-like farm tool used in ancient China in advance with ring base contact position (endoporus and end face) with the proper speed active rotation; Behind main roll milling wheel incision ring base surface, tangent direction friction power continues band change part as relay and the core roller rotates.Along with the carrying out of spreading process, it is consistent with the outer peripheral lines speed of main roll milling wheel that the linear velocity of ring periphery still keeps, but the linear velocity in interior week of ring progressively enlarges along with the ring endoporus and increases sharply; And causing the raising of core roller rotating speed, the core roller became passive belt by active rotation change the sixth of the twelve Earthly Branches this moment, when rotating speed surpasses the rotating speed that oil motor provides; Mono-directional overrun clutch makes the secondary and decelerator disengagement of machine driving, and oil motor is in unloading condition, and the oil motor inlet pressure reduces suddenly; Cause adjustable pipe rupture valve action; Stop the oil motor fuel feeding, after this, normal spreading process is proceeded to accomplish until operation.When adopting motor, then it directly being linked to each other with input shaft of speed reducer gets final product, and its function and the course of work and oil motor are similar.

This device is an independently attachment mechanism of vertical Ring Rolling Machine, newly make machine setting or retrofitting of used machine acquire all can, it can realize operation automatically with the main frame interlock, along with the beginning or the end of looping mill rolling operation, this device state that gets into automatically or deactivate.。

The beneficial effect of the core roller tumbler of the vertical Ring Rolling Machine of the utility model:

1, solves the difficulty that causes ring base band not change because of the overweight or inside and outside garden of ring base off-centre in the vertical Ring Rolling Machine production, given the operation band fork-like farm tool used in ancient China of rolling over the ring starting stage convenient, enhanced productivity, reduced loss due to spoiled work.

2, reduced specification requirement, reduced cost the ring base of large ring.

3, for common vertical Ring Rolling Machine maximizes possibility is provided.
