Description
Technical field
The present invention relates to a kind of planetary rolling three roller roller head unit, belong to processing equipment technical field.
Background technology
Planetary rolling is the high reduction mill of a kind of continuous rolling, has efficiently, drafts is big, elongation percentage is big, structure
Simply, advantage compact, easy and simple to handle, it is not necessary to post bake, that be suitable for the alloy steel products of rolling difficulty deformation.At present, domestic layman
Star mill milling red copper casting technology is ripe, oneself extensively applies, but BFe10-1 copper alloy strand to be rolled is by the rolling work of red copper
Skill tube rolling base is just difficult to, and because BFe10-1 copper alloy blank hot deformation temperature is higher than red copper strand, causes roller head surface
Skidding the most wear-resisting, easy pushes away to enter with pusher, causes strand recrystallization temperature and is not sufficiently stable, product quality can not be stablized, causes
Production cost rises, and result makes the technique of this rolling BFe10-1 copper alloy tube cannot be promoted and apply, thus governs city
To high request copper alloy dish, straight tube direction on development.
Along with client to copper alloy dish, straight tube demand under, planetary rolling shuts out ∮ 4,8*2 4 pipe of high-quality, fall
Low production cost, becomes an important step in whole copper alloy dish, straight tube production process.
Summary of the invention
The invention aims to solve difficulty when existing planetary rolling mill roller carries out rolling BFe10-1 copper alloy tube
Bigger problem, it is provided that a kind of simple in construction, planetary rolling three roller roller head unit compact to design.
The present invention adopts the following technical scheme that a kind of planetary rolling three roller roller head unit, including three roller heads, and three
Roller head is arranged in circular turned dish third dividing equally, and each roller head is cone, described roller head from afterbody to top
Include successively afterbody nip district, middle concentrate deformed area, head clear area and outlet sizing area, described afterbody is nipped district and centre
Concentrating deformation interval to be disposed radially some concavo-convex lines, the oblique line that the axis projection of described concavo-convex line is formed is sinusoidal bent
Line.
Further, described concavo-convex line includes 11.
Further, the material of described roller head is Y4 steel, and the use hardness of described Y4 steel is 49～52HRC.
Further, the depth H of described concavo-convex line is 0.75～0.85mm, the arc radius R of concavo-convex line be 6.60～
6.70mm。
Further, the roll off angle 49 of described three roller heads～50 °, drift angle adjustment amount is 7～8 °.
Present configuration is simple, compact to design, easy to use, has the roller head of concavo-convex line when high speed rotating, makes casting
Base can be nipped well, and entrance is middle concentrates deformed area, reduces the resistance that blank advances, advantageously reduces roll and deforming
Roll-force in journey, is therefore more suitable for the rolling of BFe10-1 copper alloy tube.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1-Figure 3, a kind of planetary rolling three roller roller head unit, including three roller heads 1, the material of roller head 1
Matter is Y4 steel, and the use hardness of Y4 steel is 49～52HRC, and three rolls 1 are arranged in circular turned dish third dividing equally, and three are rolled
The roll off angle 49 of roller 1～50 °, drift angle adjustment amount is 7～8 °, and each roller head 1 is cone, roller head from afterbody to top
Include successively afterbody nip district 1-1, middle concentrate deformed area 1-2, head clear area 1-3 and outlet sizing area 1-4, afterbody is nipped
District 1-1 and middle concentration have been disposed radially some concavo-convex lines 2 between deformed area 1-2, and it is oblique that the axis projection of concavo-convex line 2 is formed
Line is sine curve, and concavo-convex line 2 includes 11, and the depth H of concavo-convex line 2 is 0.85mm, and the arc radius R of concavo-convex line 2 is
6.60mm。
A kind of rolling using roller head of the present invention to carry out BFe10-1 copper alloy tube, step is:
(1) open the main and auxiliary motor of planetary rolling, after rotating speed is reached predetermined value, BFe10-1 copper alloy hollow strand is pushed
In planetary rolling central canal；
(2) by the rotation of uniform three rolls of the trisection in rotary disk controlled by auxiliary motor, strand is made to nip entrance
Middle concentrating deformed area friction, instantaneous be warming up to 850～980 DEG C and carry out thermal deformation rolling, roll assembly roll off angle is 50 °, partially
Angle adjustment amount about 7～8 °；
(3) producing differential rotation when the deep bid that mair motor controls and roller rotational, the copper making to shut out by adjusting roll rotational speed closes
Gold pipe does not rotates, and by Runout area and sizing outlet area, nitrogen protection and the cooling rapidly of water, makes the BFe10-1 copper shut out close
Gold pipe have fine isometric crystal grains, good plasticity thus realize overlong copper alloy pipe in wire reel-up.
In the present invention roll afterbody nip district with on the middle taper seat concentrating deformed area, radially and compartment of terrain distribution
The concavo-convex line having annular is set to 11, and the oblique line that the axis projection of this concavo-convex line is formed is sine curve, concavo-convex line
Degree of depth 0.85mm, the arc radius R of concavo-convex line is 6.60mm so that has the roll of concavo-convex line when high speed rotating, makes
BFe10-1 copper alloy hollow strand can be nipped well, and entrance is middle concentrates deformed area, reduces the resistance that blank advances, favorably
In reducing roll roll-force in deformation process.BFe10-1 copper is can ensure that in the operation of rolling of BFe10-1 copper alloy tube
Alloy casting blank blank nip smoothly and continuously, stable, roll expeditiously, and when avoiding blank deformation, instability produces acutely
Rock, thus the surface quality of influence of rolled pipe, and the tubing pitch rolled out in actual job is uniform and stable, simultaneously
The service life of roll is the most significantly extended 2～3 times.
