Description

Technical Field

[0001] The utility model relates to the field of heat treatment of titanium and titanium alloy bars, in particular to a material distribution device for preventing titanium alloy bars from deforming during vacuum heat treatment. Background Art

[0002] Titanium and titanium alloys have the advantages of high specific strength, excellent corrosion resistance, good biocompatibility, etc., and are widely used in aviation, aerospace, shipbuilding, nuclear industry, petroleum, chemical industry, medical and other fields. The production of titanium and titanium alloy bars goes through smelting, forging, rolling, finishing and other processes. The long processing flow leads to large residual stress in the bars. At the same time, due to the relatively small elastic modulus of titanium and titanium alloys (100-120GPa), the bars are very easy to deform during machining and cannot meet the precision requirements of parts.

[0003] In order to eliminate the residual stress inside the material, traditional titanium and titanium alloy bars are often vacuum heat treated. In order to avoid deformation of the titanium and titanium alloy bars during vacuum heat treatment, a rack must be used for material distribution. The existing racks generally use V-shaped channel steel to facilitate the arrangement of the bars and not easily entangled. However, the current V-shaped grooves are all prepared by welding. The welding process itself is prone to thermal deformation, and the V-shaped grooves after welding cannot be leveled for a second time. The deformation of the V-shaped groove is more likely to cause deformation of the titanium and titanium alloy bars during vacuum heat treatment. Utility Model Content

[0023] See also Figures 1-2 In the embodiment of the utility model, a material distribution device for preventing deformation of titanium alloy bars during vacuum heat treatment comprises a frame 9, a support plate 5, a U-shaped groove plate 8, and a V-shaped groove plate

[0024] The details are as follows, including:

[0025] See also Figure 1 , Figure 2 , a frame 9, wherein the frame 9 is formed with at least two receiving surfaces;

[0026] A plurality of support plates 5 are mounted on the receiving surface, and a U-shaped groove plate 8 is formed at the side end of the support plate 5;

[0027] The V-shaped groove plate is placed on the support plate 5 and is detachably connected to the U-shaped groove plate 8 .

[0028] Among them, the frame 9 is composed of two groups of truss structures arranged in parallel, and the truss structure includes an upper truss and a lower truss. Multiple groups of support columns are connected between the upper truss and the lower truss. The two upper trusses are connected to form a receiving surface. The two upper trusses are installed with multiple groups of connecting columns, and support plates 5 are installed on the connecting columns. The upper truss and the lower truss are respectively installed with multiple groups of upper lifting holes 3 and lower lifting holes 4 to facilitate the rapid installation of the frame 9 and prevent the frame 9 from shaking and affecting the laying of the rods.

[0029] In detail, in this embodiment, the subject matter described in the utility model is adopted. When in use, titanium and titanium alloy bars are laid in the above-mentioned V-groove. The V-groove plate that can be detachably installed through the U-groove plate 8 and the support plate 5 can avoid thermal deformation caused by welding, thereby avoiding affecting the laying of the bars. The V-groove plate can move along the length direction of the U-groove plate 8 during thermal expansion and contraction, preventing the V-groove plate from bulging and causing no bending deformation. The utility model maximizes the flatness of the V-groove plate, so that the straightness of the material can be ensured after the vacuum heat treatment of the bar.

[0030] A limiting plate 6 is installed on the upper truss of the frame 9 .

[0031] A plurality of rollers 1 are mounted on the bottom of the frame 9 .

[0032] Two groups of parallel front baffles 2 are provided at the ends of the frame 9 along the length direction, and the front baffles 2 are threadedly connected to the frame 9 .

[0033] The support plate 5 is arranged in a W-shaped structure, and two groups of V-shaped groove plates are installed on the support plate 5 .

[0034] The V-shaped groove plate is composed of two inclined side plates 7, the two side plates 7 are arranged at an equal distance, and the side plates 7 are detachably connected to the U-shaped groove plate 8.

[0035] To elaborate, in order to prevent the side panel 7 from deforming and affecting the fabrication of the rod, screw connection is adopted to avoid thermal deformation caused by welding. If the side panel 7 is deformed during later use, it can be removed and repeatedly leveled, which can increase the service life of the side panel 7.

[0036] The U-shaped groove plate 8 is formed with a strip-shaped through hole, and the side plate 7 is formed with a countersunk hole. The bolts penetrate the strip-shaped through hole and extend into the countersunk hole and are threadedly connected with the countersunk hole.

[0037] The countersunk hole passes through the side plate 7 , and when the bolt is connected to the countersunk hole, the end of the bolt does not protrude from the countersunk hole.

[0038] The side plate 7 is connected to the support plate 5 via a U-shaped groove plate 8, which is directly welded to the bottom plate. Countersunk holes are punched on the side plate 7, and countersunk bolts are connected to the U-shaped groove plate 8 with nuts. A certain gap is set between the bolts and the U-shaped groove plate 8, so that the side plate 7 can move along the length direction during thermal expansion and contraction, preventing the side plate 7 from bulging and bending deformation, thereby ensuring the flatness of the V-shaped groove plate, so as to realize the laying of titanium and titanium alloy bars in the above-mentioned V-shaped groove, and the straightness of the bars can be ensured after vacuum heat treatment.

[0039] At least four groups of the U-shaped groove plates 8 are arranged on the support plate 5 , and the side plate 7 is connected to at least one group of the U-shaped groove plates 8 .
