Abstract
The utility model relates to a special fixture among long roof beam forging heat treatment process of large -scale metal, included jib (1), lifted by crane frame (9) and connecting rod (2), lifted by crane frame (9) and form by first crossbeam (3), second crossbeam (7), first gear pole (4), fixed frame (5), roof beam frame (6), second shelves pole (8). Adopt the utility model discloses the special fixture of making, solved among the heat treatment process of long roof beam class forging the warpage with turn round the curved condition, satisfied the angularity requirement of certain model machine to long roof beam class forging to cheap cost is implemented to this frock, easily realizes.
Description
Technical field
The utility model relates to the technical field of the special tooling in metal forging heat treatment process, the technical field of the special tooling particularly in a kind of band large-scale metal long beam forging heat treatment process.
Background technology
Along with the batch production of certain model machine, the metal long beam shape Forging that length reaches more than 2.5m is increasing, mostly is in the past forge state blank form directly to heat-treat, process redundancy is large, forging is thick, not yielding in heat treatment process, but along with improving constantly of customer requirement, require that forging state is heat-treated after roughing again, monolateral surplus after roughing is within 7mm, and forging muscle is many and thin, complex-shaped, if roughing postheat treatment, the transfer of forging is according to the mode at traditional chain suspension two ends, can sink under gravity in the middle of forging, two ends tilt, again because forging wall thickness is thinning, little with the contact surface of chain, easy run-off the straight, thus the distortion that is distorted, thus cause the loss that can not save, therefore this size forging is heat-treated to is a difficult point.
Utility model content
Technical problem to be solved in the utility model is: in order to reduce the warpage after the thermal treatment of existing band large-scale metal long beam forging, reduce because forging wall thickness is thinning, little with the contact surface of chain, the torsional deformation that easy run-off the straight produces, designs the unit clamp in a band large-scale metal long beam forging heat treatment process.
The technical solution of the utility model is:
Unit clamp in a band large-scale metal long beam forging heat treatment process, it is characterized in that, comprise lifting boom (1), play hanging box (9) and union lever (2), union lever (2) becomes skewed, middle outstanding place is welded on lifting boom (1), lifting boom (1) two ends reserve certain distance for chaining bar, and all the other places contacted with a hanging box (9) all adopt the gimmick of welding to be connected with a hanging box (9);
Described hanging box (9) is made up of first crossbeam (3), second cross beam (7), the first lever (4), fixed frame (5), beam frame (6), the second lever (8);
Wherein, beam frame (6) is fixed on first crossbeam (3) and second cross beam (7) equally spacedly;
Wherein, the dead air space formed by first crossbeam (3), second cross beam (7), the first lever (4) and beam frame (6) is fixed frame (5), and this fixed frame (5) holds up the rod iron of forging for inserting;
Whole hanging box (9) side, without lever, is facilitate forging to put into fixture; Opposite side arranges the second lever (8), is prevent forging from passing from opposite side.
Described lifting members of frame all adopts welding or riveted joint.
The material employing sheet material that described fixture is used and bar, as long as specification size can bear forge weight.
Described fixture can be equipped with the rod iron of branched φ 100.
The beneficial effects of the utility model are: original forging to the type, when heat-treating, takes on stove, all adopt the mode sling in two of forging by direct chain, and due to deadweight during forging high temperature, after two is stressed, interlude sinks, thus result in warpage; And due to the imbalance that the point of contact of chain two ends and forging is stressed, result in the distortion of forging.
Compared with original stove mode that takes on, with special tooling when taking on stove, the stressed area of forging becomes large, and uniform force, can not produce warpage and distortion.Solve the warpage in the heat treatment process of long beam forging and twisting situation, meet the angularity requirement of certain model machine to long beam forging, and this frock implementation cost is cheap, be easy to realize.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model heat treated unit clamp one better embodiment;
Fig. 2 is left view;
Fig. 3 is right view.
Wherein, 1-lifting boom, 2-union lever, 3-first crossbeam, 4-first lever, 5-fixed frame, 6-beam frame, 7-second cross beam, 8-second lever, 9-play hanging box.
Embodiment
Below by specific embodiment, the utility model is given and further detailed description:
Adopt long beam forging to it in the design of certain model machine, be TC4-DT titanium alloy according to design requirements selection, length is 3520mm, requires that amount of warpage is monolateral and is not more than 4mm.This forging adopts warpage preventing method described in the utility model to heat-treat.
To on the open hearth base plate of the heat treated stove of forging, will place isometry block uniformly, the spacing of isometry block can not more than 500mm.After forging carries out roughing, be transferred in heat treatment furnace, be placed on the isometry block of drop-bottom, pad and prop up surely, heat-treat, Heating temperature is at about 1000 DEG C.When coming out of the stove, open fire door, release drop-bottom, lifting boom (1) two ends of fixture are hung over chain, sling by fixture, fixture outwardly, is transferred to above chassis by the side making the second lever (8), reduce fixture height, make the bottom level of height lower than forging of clamp base second cross beam (7), translational clamp, is inserted in fixture from open-mouth by forging, until make forging put into the middle part of fixture, the second lever (8) prevents forging from shifting out fixture.Then, workman, by rod iron, inserts, through fixture, passes from the fixed frame (5) of another side in 4 fixed frames (5) of fixture.Rise fixture, forging acts on rod iron, raises along with the rise of fixture, thus is transferred to cooling zone.
This forging amount of warpage after air cooling to room temperature of coming out of the stove is 2mm, and meet the angularity requirement of certain model machine to long beam forging, the method for described warpage preventing executes low cost, is easy to realize.
