Background

In the field of titanium alloy application, titanium alloy sections such as channel titanium, angle titanium, S-shaped titanium and the like are generally produced by adopting an extrusion mode. Due to the fact that in the extrusion process, after the extruded titanium material leaves the extrusion die, due to the fact that the extruded titanium material is a profiled bar, cooling is not uniform, and the finally obtained titanium alloy profile is not straight and has bending or even serpentine bending.

One of the existing straightening methods is to directly move up a straightening machine; the other is to take out the steel after being heated in a heating furnace and then to lift the steel on a tension leveler. When the titanium alloy section bar is pulled and straightened in a cold state and meets a titanium alloy section bar with a slightly larger size, the pulling force of a general pulling and straightening machine is very large, and for a TC4 titanium alloy section bar with the size of 40 multiplied by 5, because the pulling force is insufficient, the groove titanium cannot be effectively straightened, and the clamping force of a chuck of the pulling and straightening machine is often insufficient. When the heated titanium is taken out for tension straightening, the requirement of tension is reduced, but the upper and lower tools cannot be directly finished by the channel titanium at the temperature of about 750 ℃, and the problem of uneven cooling still exists after tension straightening, so that the straightening effect is not ideal.

Referring to fig. 1, a specific structure of an embodiment of an auxiliary device for straightening of the titanium slot according to the present invention is shown. The device comprises a 310S main body 1, a first 310S bolt 3 and a second 310S bolt 4; the 310S main body 1 is of a groove-shaped structure corresponding to the groove titanium 2; through holes 11 are formed in the corresponding positions of the left middle parts of the two side walls of the main body 1 of the 310S, and transverse strip-shaped holes 12 are formed in the corresponding positions of the right middle parts of the two side walls; the first 310S plug pin 3 is correspondingly arranged between the through holes 11 at the two sides of the 310S main body 1; the second 310S plugs are correspondingly arranged between the strip-shaped holes 12 on the two sides of the 310S main body 1.

When the straightening device is used, round holes corresponding to the through hole 11 and the strip-shaped hole 12 are respectively formed in the corresponding positions of the left side and the right side of the two side walls of the titanium 2 of the groove to be straightened, the titanium 2 of the groove to be straightened is correspondingly arranged in the 310S main body, the left round hole corresponds to the through hole 11, and the right round hole corresponds to the strip-shaped hole 12; the first 310S bolt 3 sequentially penetrates through the through hole 11 in the left side of the 310S main body 1 and the round hole in the left side of the groove titanium 2 to fix the two ends, and the second 310S bolt sequentially penetrates through the strip-shaped hole 12 in the right side of the 310S main body 1 and the round hole in the right side of the groove titanium 2 to fix the two ends. And (3) conveying the auxiliary device with the mounted groove titanium 2 into a heating furnace, preserving heat for 2 hours at 750 ℃, and then cooling along with the furnace to finish the straightening of the groove titanium 2.

The invention is further illustrated by the following specific examples:

the general TC4 slot titanium has the cross section size of 5mm in thickness, three side lengths of a groove-shaped structure are all 40mm, and the total length is about 3000mm. The auxiliary device of the utility model is designed for this purpose, the thickness is 20mm, the width is 100mm, the 310S stainless steel plate with the total length of 3400mm is welded into a 310S main body with a concave structure corresponding to TC4 groove titanium, two phi 22mm through holes are correspondingly arranged at the left side of the two side walls near the left end by 150mm, the right side of the two side walls near the right end by 400mm is provided with a strip hole starting point, the end point of the strip hole is arranged near the end by 200mm, the strip hole is 22mm high, the two ends are semicircles with the diameter of phi 22mm, and the smooth transition is realized; two round holes phi 22mm are correspondingly formed in the positions, 50mm away from the left end, of the left sides of the two side walls of the TC4 groove titanium, and two round holes phi 22mm are correspondingly formed in the positions, 50mm away from the right end, of the right sides of the two side walls; and additionally processing 2 310S bolts with the diameter phi of 20mm and the length of 150mm, drilling pin holes at two ends of each bolt, inserting iron wires for fixing after fixing the groove titanium, and preventing the bolts from falling out. The 310S stainless steel is high temperature resistant stainless steel, can keep the strength and hardness of the material below 800 ℃, and can ensure that the tool is not softened when being used in a heating environment of 750 ℃.
