Abstract
The utility model relates to the technology of the hot straightening of a stepped shaft, in particular to a straightening device of cross wedge rolling shafts. A support seat is provided with an upper straightening rod, a lower straightening rod and a movable straightening rod which are in parallel with each other and are matched with the shape of a workpiece to be straightened, the axis lines of the upper straightening rod and the lower straightening rod are on the same plane and have an inclined angle alpha which is 30 degrees to 45 degrees relative to a vertical plane, the distance H between the axis line of the upper straightening rod and the axis line of the lower straightening rod is 18-25mm, and the upper straightening rod and the lower straightening rod are driven by a motor; and the axis lines of the movable straightening rod and the workpiece to be straightened are on the same plane and are vertical to the plane where the axis lines of the upper straightening rod and the lower straightening rod are positioned, and the movable straightening rod is driven by a pneumatic cylinder to forward or backward move. By adopting the hot straightening device, two straightening workers are reduced to double the production efficiency, the straightening precision is improved, and the quality of products is guaranteed.
Description
Technical field
The utility model relates to the hot alignment technology of multidiameter, particularly a kind of cross-wedge-rolling shaft product coalignment.
Background technology
Cross wedge rolling machine is the special equipment that is used for producing in a large number multidiameter in forge producing, can distortion after the axis products forging cooling after rolling.Adopt at present the cold school of axis products forging is handled, cold school difficulty is big, low precision, and inefficiency is also wasted time and energy.
The utility model content
The utility model purpose provides a kind of a kind of cross-wedge-rolling shaft product coalignment that overcomes above-mentioned defective.
Technical solutions of the utility model: a kind of cross-wedge-rolling shaft product coalignment, on bearing, be equipped with three parallel to each other, with by colonel's straight-bar of gyp's part profile coupling, alignment bar, moving alignment bar down, coexist plane and vertical plane angle α of alignment bar axial line is 30 °-45 ° up and down, distance H is 18-25mm between the alignment bar axial line up and down, and the alignment bar is by motor-driven up and down; Moving alignment bar axial line and coexisted by gyp's part axial line plane and the alignment bar axial line up and down plane that coexists is vertical, moves the alignment bar and is advanced by the pneumatic cylinder drive or retreat.
Coexist plane and vertical plane angle α of alignment bar axial line is 30 ° up and down, and distance H is 22mm between the alignment bar axial line up and down.
After adopting this hot calibration device, reduced by two alignment workmans, just finished alignment work before the axis products cooling, need not carry out cold school again, production efficiency doubles; The alignment precision is improved, and product quality has had guarantee.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is an A-A cut-away view among Fig. 1.
1 colonel's straight-bar among the figure, 2 times alignment bars, 3 moving alignment bars, 4 pneumatic cylinders, 5 location of workpieces, 6. bearing, α is alignment bar axial line up and down coexist plane and vertical plane angle, H be about distance between the alignment bar axial line.
The specific embodiment
Axis products is rolling finish after, at once carry out alignment, be referred to as hot school.Hot school is easier carries out, and can solve the problem of cooling back distortion.
By three with the alignment bars of axis products (by gyp's part) profile coupling (profile coupling be meant alignment bar with by corresponding, the consistent size of gyp's part contact site profile convex-concave), three Different Diameter to axis products is clamped, and roll, the deformed shaft series products is under the rolling extruding of three alignment bars so, profile, axiality etc. just can obtain correcting, and meet design requirement.
With rolling finish put into Fig. 2 sequence number 5 positions by gyp's part, promote pneumatic cylinder, three alignment bar cramps are tightly rolled simultaneously by gyp's part, like this, distortion is squeezed in rotation process by gyp's part, corrects distortion.Shrink pneumatic cylinder, moving alignment bar retreats, and takes out by gyp's part, finishes by the alignment of gyp's part.Alignment bar rotation is by motor-driven up and down, and moving alignment bar is being with together when clamping by gyp's part and is being rotated, and moving alignment bar is also driven by pneumatic cylinder and to advance or retreat.
Distance H is 18-25mm between the alignment bar axial line up and down, and coexist plane and vertical plane angle α of alignment bar axial line is 30 °-45 ° up and down, and proposed parameter is α=30 °, H=22mm.
Claims (2)
1. cross-wedge-rolling shaft product coalignment, it is characterized in that: on bearing, be equipped with three parallel to each other, with by colonel's straight-bar of gyp's part profile coupling, alignment bar, moving alignment bar down, coexist plane and vertical plane angle α of alignment bar axial line is 30 °-45 ° up and down, distance H is 18-25mm between the alignment bar axial line up and down, and the alignment bar is by motor-driven up and down; Moving alignment bar axial line and coexisted by gyp's part axial line plane and the alignment bar axial line up and down plane that coexists is vertical, moves the alignment bar and is advanced by the pneumatic cylinder drive or retreat.
2. a kind of cross-wedge-rolling shaft product coalignment according to claim 1 is characterized in that: coexist plane and vertical plane angle α of alignment bar axial line is 30 ° up and down, and distance H is 22mm between the alignment bar axial line up and down.
