Abstract
The invention discloses a forge welding structure hinge beam for a cubic hydraulic machine. The forge welding structure hinge beam comprises a middle barrel and two groups of opposite connecting lugs which are arranged in the transverse direction and longitudinal direction of the middle barrel, wherein the middle barrel is a forging; the connecting lugs are plates; the middle barrel and the connecting lugs are welded into a whole; the middle barrel and the connecting lugs are weldable alloy steel in which C is less than or equal to 0.3 percent, and sigma s is more than or equal to 600MPa; and the weld seam strength of the middle barrel and the connecting lugs is not less than 80 percent of the strength of the weldable alloy steel. By adopting the split structure of the middle barrel and the connecting lugs, the characteristics of the low-carbon high-strength weldable alloy steel which are newly developed are utilized, the middle barrel and the connecting lugs which are made of the same-quality material are welded to produce the hinge beam, the part manufacturing process is simple, and the overall strength is high.
Description
(1) technical field:
The present invention relates to the hydraulic press parts, specifically a kind of cubic hydraulic press smithwelding structure hinge beam for the production of the superhard material product.
(2) background technology:
The superhard material cubic hydraulic press is the operation principle of utilizing cubic apparatus, promote six hard alloy top hammers by hydraulic synchronization synthetic material is pushed the generation high pressure, and heat generation high temperature by the low-voltage high-power electric current, make the generation qualitative change of synthetic material interior tissue and form the process of new superhard material.The top of cubic hinge press is pressed and is subjected to hydraulic control, by piston in working cylinder motion and promote to finish.
Described working cylinder is installed in the cavity of hinge beam, is hinged by connecting auricle between described each hinge beam.The traditional structure of described hinge beam is monoblock cast or solid forging, and there is the problem of short texture, coarse grains in the cast-in-block hinge beam, and the hinge beam of solid forging exists connection auricle root to forge the problem of saturating and processing difficulties.
Along with the specification of cubic hydraulic press is done larger and larger, ￠ 650 cubic hydraulic press for example, its operating pressure of single cylinder reaches 32MN, the connection auricle maximum weighted face of each hinge beam is difficult to bear so huge and causes fracture damage, because the defective of hinge beam traditional structure, the easiest 45 ° of sections of pin-and-hole that appear at of fracture that connect auricle cause hinge to lose efficacy.
(3) summary of the invention:
For the weak point of hinge beam traditional structure, the purpose of this invention is to provide a kind of stressed cubic hydraulic press smithwelding structure hinge beam of hinge beam of strengthening.
Can realize the cubic hydraulic press smithwelding structure hinge beam of above-mentioned purpose, cylindrical shell and be located at two group relative the connect auricles of centre cylindrical shell on horizontal and vertical in the middle of comprising, difference is that described middle cylindrical shell adopts forging, described connection auricle adopts plate, middle cylindrical shell with connect auricle and be welded into one; But cylindrical shell and connection ear adopt the welding alloy steel of C≤0.3%, σ s 〉=600Mpa in the middle of described, be to guarantee connectivity robustness, but middle cylindrical shell are not less than 80% of welding alloy hardness of steel with the weld strength that connects auricle.
Adopt annealing process to eliminate weld stress after the welding.
The whole modifier treatment of hinge beam after the welding.
It is 2～4 that each group connects auricle.
In the conventional design, one group of connection auricle is designed to 2, and another group connects auricle and is designed to 3.
Advantage of the present invention:
Cylindrical shell and the Split type structure that connects auricle in the middle of cubic hydraulic press smithwelding structure hinge beam of the present invention adopts, but utilize the recently successful Low-carbon High Strength welding alloy product made from steel characteristic of research and development, to make hinge beam with connecting the auricle welding with the middle cylindrical shell of product material, the part process is simple, and bulk strength is high.
(4) description of drawings:
Fig. 1 is the structural representation of one embodiment of the present invention.
Fig. 2 is the top view of Fig. 1 embodiment.
Figure number sign: 1, middle cylindrical shell; 2, connect auricle.
(5) specific embodiment:
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
As shown in Figure 1, hinge beam 1 is placed vertically, (its inner chamber upwards), the mid portion of described hinge beam is middle cylindrical shell 1, the horizontal both sides of cylindrical shell 1 respectively arrange one group of connection auricle 2 in the middle of described, vertical both sides of middle cylindrical shell 1 respectively arrange one group and connect auricle 2, as shown in Figure 2, described in the middle of cylindrical shell 1 with connect that the employing welding manner is connected between the auricle 2.
The quantity that each group connects auricle 2 is 2～4.
Shown in Fig. 1, Fig. 2 embodiment, one group (vertically) connects auricle 2 is two, and it is three that another group (laterally) connects auricle 2.
But cylindrical shell 1 and connection auricle 2 all adopt the welding alloy steel of C≤0.3%, σ s 〉=600Mpa in the middle of described, middle cylindrical shell 1 is forging, connecting auricle 2 is plate, and welding requirements is: but middle cylindrical shell 1 is not less than 80% of welding alloy hardness of steel with the weld strength that connects auricle 2.
Adopt annealing process to eliminate weld stress after the welding.
The whole modifier treatment of last hinge beam.
