Description

Technical Field

[0001] The invention relates to the technical field of equipment for heat treatment of large rings, and in particular to an anti-deformation tool for quenching large rings. Background Art

[0002] Large rings are heated in the furnace for solution treatment and quenching. When loading the furnace, the rings need to be placed in the material frame. The material frame generally has four hanging points, which are distributed at the four corners or two sides of the material frame. The larger the ring, the larger the furnace and the larger the material frame must be. The farther the four hanging points of the material frame are from each other, the worse the rigidity of the material frame will be. Under the combined effects of the material frame's own gravity, the ring's gravity, the high-temperature environment in the furnace and the sudden cooling by water, the material frame will deform. The farther from the hanging point, the greater the deformation. The entire material frame will show a spherical or folded or irregular deformation of the bottom of the pot. The support point of the ring placed in the material frame will change, the suspended part will sag, warp, and elliptical deformation will occur. In severe cases, the ring size cannot meet the requirements of part processing and will be scrapped.

[0003] In addition, the larger the material frame is, the more materials are used to strengthen the rigidity. At the same time, the weight of the material frame cannot be increased indefinitely. Therefore, the diagonal support beams are relatively scarce, and the ring support points are also reduced. The rings are also prone to deformation due to the scarcity of support points. The deformation of the quenching material frame is a physical phenomenon that cannot be avoided. The deformation can be reduced by strengthening the rigidity of the structure, but the effect is limited. The deformation of the material frame is still unavoidable and will increase the weight of the material frame, resulting in a reduction in the effective furnace load. In addition, the material frame also wastes heating energy.

[0004] The existing traditional technical solution is that the four hanging points of the material frame are distributed on the four corners or two sides of the material frame. The larger the material frame is, the farther the four hanging points are from each other, and the worse the rigidity of the material frame is. Under the combined effects of the material frame's own gravity, the ring's gravity, and the high-temperature environment in the furnace, the material frame will deform, causing the ring to warp and elliptical deformation. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an anti-deformation tooling for quenching large rings. It utilizes the lever principle of equal distance and equal deformation to effectively solve the problem of uneven deformation of the quenching frame, so that the deformation of the plane where the ring is located is always kept consistent. Regardless of the deformation of the frame, the support surface of the ring is always close to the same plane, thereby avoiding quenching deformation of the ring.

[0006] The technical solution provided by the present invention is as follows: A deformation prevention tool for quenching large rings, comprising a main frame, a plurality of balancing beams and a plurality of transfer beams, wherein the inner side of the main frame is provided with a regular polygonal plane structure for placing the rings, which is formed by a plurality of oblique support beams and an outer frame of the main frame, the balancing beam is arranged on the inner side of the oblique support beam, a hanging point is arranged in the middle of the balancing beam, the transfer beam is connected to the hanging point through a hanging piece, and a furnace hanging point is arranged at the end of the transfer beam.

[0007] Preferably, the regular polygonal plane structure is a regular octagonal plane structure, and the regular polygonal plane structure is composed of an outer frame structure of the main frame and four oblique support beams.

[0008] Preferably, the number of the balancing hanging beams is consistent with the number of the oblique supporting beams, and the balancing hanging beams are arranged in parallel with the oblique supporting beams.

[0009] Preferably, the number of the transfer suspension beams is two, and the two transfer suspension beams are arranged in parallel and symmetrically about the midline of the regular polygonal plane structure.

[0010] Preferably, the main frame, the oblique support beams, the balancing suspension beams and the transfer suspension beams are all vertically symmetrical structures.

[0011] Preferably, the suspension point is arranged at the exact center of the balance suspension beam.

[0012] Preferably, a support rod is provided between two adjacent balancing suspension beams.

[0013] Preferably, the connection points between the support rods and the balance suspension beam are located on the left and right sides of the suspension point, and a plurality of support rods are enclosed to form a regular polygonal structure.

[0014] Preferably, the main frame is a regular quadrilateral structure.

[0015] Preferably, the main frame, the oblique support beams, the balancing suspension beams and the transfer suspension beams are all square steel tubular structures.

[0016] The present invention has the following advantages over the prior art: The anti-deformation tooling for quenching large rings of the present invention utilizes the principle of equal distance and equal deformation of the lever, so that no matter how much the main frame is deformed, the deformation of the regular polygonal plane structure where the ring is located can remain consistent, so that the plane where the ring is located is always an approximate plane; in addition, the present invention can reduce the length of the lever arm by more than 1 / 2 through design, and the rigidity is more sufficient. At the same time, the present invention uses 12 support points of a regular octagonal outer frame + a regular dodecagon to make the support points more and more uniform, avoiding the deformation of the ring due to insufficient support points during quenching. The anti-deformation tooling for quenching large rings of the present invention has a symmetrical structure up and down, and can be turned over for use after bending and deformation, so that the material rack is always in good condition.

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-6 As shown, an embodiment of the present invention provides an anti-deformation tooling for quenching large rings, including a main frame 1, four balancing beams 2 and two transfer beams 3. A regular octagonal plane structure for placing a ring 5 is provided on the inner side of the main frame 1, which is formed by four oblique support beams 4 and an outer frame of the main frame 1. The regular octagonal plane structure can evenly support the entire circumference of the ring. The balancing beam 2 is arranged on the inner side of the oblique support beam 4. A hanging point is provided at the center of the balancing beam 2. The transfer beam 3 is connected to the hanging point through a hanger 6. A furnace hanging point is provided at the end of the transfer beam 3.

[0022] like Figure 4 As shown, in this embodiment, the structural length of the balance beam 2 is reduced by about half compared with that of the traditional material frame, and the rigidity is better. The hanging point O is located at the center of the balance beam 2, and the two ends OE and OF have the same length, and the two ends are equal in length, so that the two ends are subjected to the same force (the gravity of the tooling itself and the gravity of the ring 5 act on the two end points of the balance beam 2 consistently), so that the deformation of point E and point F is consistent, ensuring that the entire main frame 1 is always on an approximate plane, and the eight end points of the four balance beams 2 support the eight points of the ring 5, forming 12 support points of a regular dodecagon with the center point of the oblique support beam 4, so that the ring 5 supports more and more uniform force points, and the same length makes the deformation of the two ends of the balance beam 2 always consistent, no matter how much the deformation is, the main frame 1 always remains in an approximately planar shape state, reducing the quenching deformation of the ring 5; the transfer hanging beam 3 transfers the four balanced hanging points a, b, c, and d on the tooling to the original four hanging points A, B, C, and D of the furnace respectively, ensuring that all hanging points are subjected to vertical force. According to the different positions of the furnace hanging points, the plan of transferring the hanging beam 3 can be adjusted accordingly (for example, if the distance between the hanging point A and the hanging point B of the furnace is farther, the transfer hanging beam is lengthened. If the distance between the hanging point A and the hanging point C of the furnace and the distance between the hanging point B and the hanging point D are wider, the distance between the hanging point A and the hanging point C and the distance between the hanging point B and the hanging point D are widened, and a hanging beam is added to each of the a to c and b to d between the two transfer hanging beams, and the upper hanging points are transferred to the added ac hanging beams and bd hanging beams, so that the a, b, c, and d hanging points always maintain vertical force).

[0023] In this embodiment, the suspension point of the balanced suspension beam 2 can also be designed as a support point and placed on a traditional material frame, with a similar force effect.

[0024] In this embodiment, the balance suspension beam 2 is arranged in parallel with the oblique support beam 4. The two transfer suspension beams 3 are arranged in parallel and symmetrically about the center line of the regular octagonal plane structure.

[0025] In this embodiment, the main frame 1, the inclined support beam 4, the balance beam 2, and the transfer beam 3 are all symmetrical structures in an upper and lower manner. When any structure is bent or deformed during use, it can be turned over and used to minimize the impact of the bending by using anti-bending to counteract the bending.

[0026] In this embodiment, a support rod 7 is provided between two adjacent balanced hanging beams 2. The function of the support rod 7 is mainly to provide support. The support rod 7 can increase the lateral force strength of the balanced hanging beam when the balanced hanging beam is tilted or tilted. The connection points between the support rod 7 and the balanced hanging beam 2 are located on the left and right sides of the hanging point, and the four support rods 7 enclose a regular polygon structure.

[0027] In this embodiment, the main frame 1 is a regular quadrilateral structure. For a large furnace, there are generally four hanging points. For a small furnace, in other embodiments, there may also be two or one hanging points. The structure of the main frame 1 can also be adjusted accordingly according to actual conditions. The main frame 1, the oblique support beam 4, the balance hanging beam 2 and the transfer hanging beam 3 are all square steel tube structures, and the force-bearing structure is better.

[0028] In this embodiment, in order to facilitate the storage of the main frame 1 , supporting legs (not shown in the figure) may be respectively provided at the four corners of the main frame 1 .

[0029] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
