Abstract
The utility model relates to a metal capillary creep straightening device which is suitable for straightening a metal capillary the outside diameter of which is 0.5 mm-3.0 mm and is especially suitable for straightening the creep of a titanium alloy capillary. The utility model is characterized in that the straightening device comprises a stainless steel supporting column, a disk-shaped supporting frame and a clamping apparatus. The utility model has the advantages of high straightening precision, and small elongation percentage of pipe materials. After the cold-drawing curved metal capillary is straightened, the nonstraightness of the cold-drawing curved metal capillary is less than 5 mm/m, and the variations of the inside diameter and the outside diameter of the metal capillary are less than 0.01 mm; the straightening device can straighten the metal capillary simultaneously in the process of vacuum annealing, and cost is saved.
Description
The utility model relates to the creep straightening device of metal capillary, is applicable to that the aligning external diameter is the precision tube of 0.5mm-3.0mm, is specially adapted to creep straightening titanium alloy capillary.
Titanium alloy pipe after the processing, the normal appearance vertically reaches horizontal bending or reverses, could use after need aligning, the general roll straightening equipment that adopts of aligning, promptly all to and the tubing direction of advance angled and have between the hyp roller repeatedly crookedly, the bending pipes part is aligned gradually, the pressure between every pair roller is also corrected the tubing circumference simultaneously, improved the ovality of tubing, this roll straightening is aerial thermal straightening.Also need to carry out the post processing of multiple operation behind the aligning.Also have the stretcher leveling of employing equipment to carry out tube straightening, promptly apply suitable tension force to tubing under the uniform temperature in atmosphere, with tube straightening, but the percentage elongation of stretcher leveling tubing is 1-3%, and chill phenomenon is arranged.Roll straightening equipment and stretcher leveling equipment are applied to the heavy caliber pipe aligning more, are not suitable for titanium aligning capillaceous.
The purpose of this utility model is at titanium alloy characteristics capillaceous, proposes a kind of flattening precision height, and the tubing percentage elongation is little, is applicable to the creep straightening device of aligning metal capillary.
The creep straightening device of metal capillary is characterized in that this device comprises:
The stainless steel pillar, the two ends of described stainless steel pillar all are processed with screw thread, and wherein an end installs disk-shaped bracket with nut, the movable disk-shaped bracket that the other end assembles with spring leaf and stop nut;
Disk-shaped bracket, described disk-shaped bracket is positioned at the two ends of stainless steel pillar, is provided with the hole of assembling with the stainless steel pillar in the middle of the disk-shaped bracket, and is provided with the circular hole with disk-shaped bracket center symmetric arrays, prepares jig in the circular hole of symmetry;
Jig, described jig are fitted in the circular hole of symmetric arrays of disk-shaped bracket, and an end of jig is processed with screw thread and fastening with nut and disk-shaped bracket, and the other end of jig is provided with hole and the jackscrew that tightens metal capillary.
The utility model is according to the design of the creep principle of metal, compare with other straightener, have to rectify and put the precision height, the characteristics that the tubing percentage elongation is little, the metal capillary nonstraightness that makes cold drawn bending behind the aligning is less than 5mm/m, external diameter changes less than 0.01mm in the metal capillary, with this device the aligning of metal capillary is carried out simultaneously in vacuum annealing process, has saved expense.
Accompanying drawing is the utility model structure chart
By reference to the accompanying drawings the utility model is further described:
The creep straightening device of metal capillary is characterized in that this device comprises: stainless steel pillar 1, and described The two ends of rust steel strut all are processed with screw thread, and wherein an end is fixedly mounted with disk-shaped bracket with nut 2, the spacing spiral shell of the other end The movable disk-shaped bracket of mother 3, spring leaf 4 and stop nut 5 assemblings; Disk-shaped bracket 6, described disk-shaped bracket Be positioned at the two ends of stainless steel pillar, be provided with the hole of assembling with the stainless steel pillar in the middle of the disk-shaped bracket, and be provided with dish type The circular hole of carriage center symmetric arrays is prepared jig in the circular hole of symmetry; Jig 7, described jig is fitted in dish In the circular hole of the symmetric arrays of shape support, an end of jig is processed with screw thread and fastening with nut and disk-shaped bracket, card The other end of tool is provided with hole and the jackscrew 9 of chucking metal capillary 8.
During the aligning metal capillary, the two ends of metal capillary are put into the hole of jig and used jackscrew fastening, make gold It is exceptionally straight to belong to capillary, utilizes stop nut 3 and spring leaf that metal capillary is applied tension force, and the tension force p that applies looks The sectional area of material, heating-up temperature and metal capillary and deciding, i.e. P=F*S, F is metal capillary in the formula Half yield strength under given heating-up temperature, S is the sectional area of metal capillary. Regulate stop nut 5, The breaking elongation that limits metal capillary is not more than 0.5%, and the creep straightening device dress of metal capillary will be housed again Enter the vacuum annealing furnace annealing, metal capillary is aligned effectively.
Use the example of the utility model aligning metal capillary:
To external diameter 1.0mm, internal diameter 0.6mm, internal diameter precision 0.01mm, length is that the pure Ti capillary of 1000mm carries out 600 ℃ creep straightening, it is 15Kg that pure Ti capillary is applied tension force P, making pure Ti capillary total length is 1005mm, be that percentage elongation is 0.5%, carry out the vacuum annealing of 600 ℃/1hA.C. afterwards, the pure Ti capillary nonstraightness of annealing is 2mm/m, external diameter is 0.999mm, and internal diameter is 0.599mm.
