Abstract

A phase regulating device of a cross wedge rolling mill comprises a roller gear, a roller shaft, a force transmitting link and a pin shaft. A bolt is horizontally penetrated through a cross bore on a pin column after penetrating through the arm end of the force transmitting link, an inner nut and an outer nut are respectively sleeved on the bolts on the two sides of the pin column, the pin column can perpendicularly connected with the lateral face of the roller gear and can be rotated relatively, and the force transmitting link has 2-4 arms. The phase regulating device of the cross wedge rolling mill of the utility model adopts common components, which has simple structure, convenient installation, easy regulation, even force of each arm and each bolt, excellent reliability and lower fault rate.

Description

The cross wedge rolling machine phase adjusting device
Technical field
The utility model relates to a kind of mechanical phase adjusting device, particularly a kind of cross wedge rolling machine phase adjusting device.
Background technology
Cross wedge rolling machine is a kind of efficient forging equipment commonly used, and the T type groove of the equal amount that evenly distributed on two rolls of this equipment upper and lower settings, two rolls is used for installation mold.Two contrary rotations synchronously in the same way of roll will place two forging material one-shot formings between the roll up and down.
Because mould is to be placed on the roll of two circles, the location of the phase place between two molds is vital for rolling quality up and down.But cross wedge rolling machine often is used to rolling different product, mold exchange more frequently just, different moulds is difficult to accomplish highly consistent, change the centre-to-centre spacing of two rolls and change two roller centre-to-centre spacing and can cause phase difference with regard to needs, cause mould that phase difference is also arranged, and bigger phase difference will influence the rolled piece quality even the operation of rolling can't be carried out, but quite loaded down with trivial details by adjusting the align process of phase place of mould.
In order to eliminate this phase difference, on the general cross wedge rolling machine phase-regulating mechanism has been installed.Existing phase-regulating mechanism normally is installed on the bottom roll, and shown in Figure 3 is a kind of form wherein commonly used.Concrete: roller gear 1 sky is enclosed within on the roll mandrel 2, on roll mandrel 2, adorn a force transmitting link 4A, be provided with bearing pin 5A on the roller gear 1 accordingly, between force transmitting link 4A and bearing pin 5A, respectively adorn a threaded pull bar 9, two pull rod screw oppositely, opposed in opposite directions, have the double end adjusting nut 9A of respective threaded to connect with one.
In this phase-regulating mechanism, the synchronous all the time homophase of roller gear 1 and another roll is adjusted adjusting nut 9A, just can change the distance between force transmitting link 4A and the bearing pin 5A, has also just changed the phase place between roller gear 1 and the roll mandrel 2.
In this phase-regulating mechanism, force transmitting link can have two arms, and three arms, four arms also can be arranged.Arm is many more, and power transmission is big more, but corresponding structure is complicated more.
This phase-regulating mechanism is the most general, but has following defective:
1, each arm upper connecting rod is stressed is difficult to accomplish even distribution, and the result of unbalance stress very easily causes pull bar to split;
2, judge that to adjust direction indeterminate during adjusting nut, adjusting needs specific purpose tool, and process is complicated;
3, complex structure, some parts are made complicated;
Cause easily when 4, both sides are regulated to interfere with each other, not easy to operate.
The utility model content
For remedying above-mentioned deficiency, it is a kind of stressed even that the utility model provides, the simple clear and definite and simple and clear easy cross wedge rolling machine phase adjusting device of going of adjustment process of judgement direction.
The utility model cross wedge rolling machine phase adjusting device, comprise roller gear, roll mandrel, force transmitting link and bearing pin, wherein: on described force transmitting link termination, cross a bolt, the head of described bolt sinks in the described force transmitting link, bar is through on the described pin in the corresponding cross-drilled hole, on the bolt of described pin both sides, is with inner nut and outer nut respectively.
The utility model cross wedge rolling machine phase adjusting device, wherein: described pin is connected with described roller gear lateral vertical and can relatively rotates.
The utility model cross wedge rolling machine phase adjusting device, wherein: described force transmitting link has the 2-4 arm.
The utility model cross wedge rolling machine phase adjusting device, adopt general part, simple in structure, easy for installation, adjust easily, each arm and each bolt strained evenly, good reliability, fault rate is low.
Description of drawings
Fig. 1 is the schematic diagram of the utility model cross wedge rolling machine phase adjusting device;
Fig. 2 is the A-A profile of the schematic diagram of the utility model cross wedge rolling machine phase adjusting device;
Fig. 3 is existing cross wedge rolling machine phase adjusting device structure chart;
Fig. 4 is the relevant portion schematic diagram of the cross wedge rolling machine of band phase adjusting device.
The specific embodiment
For further setting forth the utility model, do more detailed explanation below in conjunction with embodiment.Fig. 1 is the schematic diagram of the utility model cross wedge rolling machine phase adjusting device.Comprising bottom roll 10, roll mandrel 2, roller gear 1, roll mandrel 2 and bottom roll 10 are one, stretch out from bottom roll 10 sides; Roller gear 1 sky is enclosed within on the roll mandrel 2.Between roll mandrel 1 and roller gear 2, tensioner cover 3 is housed.On roll mandrel 2 terminations, roller gear 1 outside, force transmitting link 4 is housed; These force transmitting link 4 five equilibriums stretch out three arms (also can be two arms, four arms), in the side of the roller gear 1 of the relevant position of each arm end, respectively establish a pin 5; Between this pin 5 and the roller gear 1, should rotate.
To pin 5, cross a bolt 6 from force transmitting link 4 arm ends, the head of this bolt sinks in the force transmitting link 4 arm ends outsides, bar passes on the pin 5 corresponding cross-drilled hole and pass suitable length, on the bolt 6 of pin 5 both sides, overlaps inner nut 8 and outer nut 7 respectively.
The power that is subjected on the roller gear 1 is sent on the roll mandrel 2 by pin 5, bolt 6 (containing outer nut 7, inner nut 8), force transmitting link 4, drives roll mandrel 2 and rotates.
When needing to adjust phase place, carry out according to the following steps:
1, each arm unclamps outer nut 7 (or inner nut 8);
2, an optional arm screws inner nut 8 (outer nut 7);
3, adjust other each arm inner nut 8 (outer nut 7) during position suitable to correct position;
4, fastening again each arm outer nut 7 (inner nut 8).
Said process is clockwise direction adjustment among the figure, is reverse adjustment in the bracket.
As seen, the utility model really have highly versatile, simple in structure, easy for installation, adjust easy, stressed evenly, can Lean on the advantage of property height, failure rate is low.
