Description

Technical Field

[0001] The invention relates to the technical field of induction normalizing devices, in particular to a rail weld electric normalizing device. Background Art

[0002] Post-weld normalizing of rail joints is another key measure to ensure welding quality. Post-weld normalizing of rail joints is a metal heat treatment process that involves secondary heating of the rails, heating the joints, holding them at this temperature for a period of time, and then cooling them in air. Its purpose is to refine the grains and even out the distribution of carbides. Existing normalizing mechanisms are installed on flash welders. Because the flash welder obscures the welded interface, deviations in the normalizing mechanism occur during processing, resulting in substandard joint processing temperatures, affecting the internal structure of the joint and, consequently, the quality of the joint during subsequent use. In severe cases, cracking of the joint may occur, reducing the safety of the rails during use. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that when the existing normalizing mechanism is installed on the flash welder, the flash welder will block the welding interface, resulting in deviations in the normalizing mechanism during processing, causing the joint processing temperature to fail to meet the standard, affecting the internal structure of the joint, and thus affecting the quality of the joint during later use. In severe cases, the joint may crack, etc., which reduces the safety of the rail during use. Now, a rail weld electric normalizing device is provided.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a rail weld electric normalizing device, comprising a transformer and a normalizing coil assembly connected to the transformer, wherein the transformer is provided with a bracket for mounting and supporting the transformer on the rail;

[0005] The normalizing coil assembly includes a first normalizing coil transition row, a first coil side, a second coil side, and a second normalizing coil transition row. The first normalizing coil transition row and the second normalizing coil transition row are arranged opposite to each other, and an insulating material is arranged between the first normalizing coil transition row and the second normalizing coil transition row. One end of the first coil side can be detachably mounted on the first normalizing coil transition row, the other end of the first coil side can be detachably mounted on one end of the second coil side, and the other end of the second coil side can be detachably mounted on the second normalizing coil transition row. A normalizing zone for normalizing the rail is formed between the first normalizing coil transition row, the first coil side, the second coil side, and the second normalizing coil transition row. Compared to the prior art, this solution uses a normalizing coil assembly with a detachable structure and cooperates with a transformer on a bracket. Its structure is simple, easy for staff to operate, and there is no obstruction, making it easy to observe the normalizing position, ensuring the normalizing zone of the rail and improving the normalizing effect of the rail.

[0006] In order to achieve detachable installation of the first coil side and the first normalizing coil transition row, in some preferred embodiments, a first connecting block is provided on one end of the first coil side, and the first connecting block is detachably installed on the first normalizing coil transition row by screws.

[0007] In order to achieve detachable installation of one end of the first coil side and one end of the second coil side, some preferred embodiments are: a second connecting block is provided on one end of the first coil side, a third connecting block is provided on one end of the second coil side, the second connecting block is provided on the third connecting block, and the second connecting block is detachably mounted on the third connecting block by screws.

[0008] In order to achieve detachable installation of the other end of the second coil side and the second normalizing coil transition row, in some preferred embodiments, a fourth connecting block is provided on the other end of the second coil side, and the fourth connecting block is detachably installed on the second normalizing coil transition row by screws.

[0009] In some preferred embodiments, a first card block is provided at one end of the first normalizing coil transition row, a second card block is provided at one end of each of the second normalizing coil transition rows, the first card block and the second card block are arranged side by side to form a third card block, a third card slot is provided on the transformer, and the third card block is clamped in the third card slot.

[0010] In some preferred embodiments, a groove with a downward opening matching the rail is provided at the bottom of the bracket, and the transformer is fixed on the top of the bracket.

[0011] In order to facilitate observation of temperature changes in the normalizing zone, preferably in some embodiments, a temperature sensor is provided on the bracket.

[0012] In order to facilitate installation of the temperature sensor on the temperature sensor, preferably in some embodiments, a temperature measuring rack is installed on the bracket, and the temperature sensor is installed on the temperature measuring rack.

[0013] In order to facilitate operation by staff, in some preferred embodiments, a handle is provided on the bracket.

[0014] In order to facilitate the operation of the staff, in some preferred embodiments, there are two handles and they are arranged on both sides of the transformer opposite to each other.

[0015] The beneficial effects of the present invention are as follows: when the electric normalizing equipment for rail welds of the present invention is used, the normalizing coil assembly of the detachable structure is used in conjunction with the transformer on the bracket. The structure is simple, which is convenient for the staff to operate, and there is no obstruction, which makes it convenient to observe the normalizing position, ensure the normalizing area of the rail, and improve the normalizing treatment effect of the rail. At the same time, compared with traditional flame normalizing, electric normalizing avoids the need to carry and store a large number of flammable and explosive items such as oxygen acetylene cylinders on site. It is convenient and safe to use, and safe and controllable. Flame normalizing is heated from the outside to the inside, which will cause coarse grains in the triangular area of the individual welds and no normal penetration. Due to the working principle of the induction normalizing machine, it is gradually heated from the inside to the outside (high frequency to low frequency), which can better refine the welds. The rail weld grains can achieve better toughness, more uniform and reliable normalizing, achieve quality controllability, simplify operation, avoid the cumbersome and dangerous handling of oxygen and acetylene cylinders, and the normalizing equipment is integrated with the rail welding unit. The main responsibility is the welding machine operator, and the construction personnel can also control it after they are familiar with the operation. At the same time, it reduces the manpower in the handling process of oxygen and acetylene cylinders, and avoids the existing normalizing mechanism being installed on the flash welder. Since the flash welder will block the welding interface, the normalizing mechanism will deviate during processing, resulting in the joint processing temperature not meeting the standard, affecting the internal structure of the joint, and also affecting the quality of the joint during later use. In severe cases, the joint will crack, etc., reducing the safety of the rail during use. BRIEF DESCRIPTION OF THE DRAWINGS
