Description

Technical Field

[0001] The present invention relates to mechanical equipment, and in particular to a steel rolling line and a processing method thereof. Background Art

[0002] The guiding arms used on engineering vehicles are usually made of steel. During the processing of the guiding arms, a series of processing treatments are required. Specifically, it is divided into: rolling treatment and heat treatment. Among them, during the rolling treatment process, in the prior art, the steel parts are usually heated and then sent to a stamping device for punching through a handling device. Then, after punching is completed, they enter a heating gas furnace for heating. After being heated to a set temperature, they are transported to a coiling machine for coiling operations. Since the punching machine and the coiling machine are distributed in different areas, manual handling by a handling cart is required, resulting in low overall efficiency. At the same time, during the transportation to the coiling machine, the temperature of the steel parts drops significantly, and more heat needs to be consumed for secondary heating, leading to high energy consumption. In view of this, how to design a rolling technology that improves processing efficiency and reduces energy consumption is the technical problem to be solved by the present invention. Summary of the Invention

[0004] The technical solution provided by the present invention is a steel rolling line, including an installation bracket, a first heating furnace, a rolling mill, a trimming and punching machine, a second heating furnace, a coiling machine, a three-dimensional moving platform, a first robot, and a second robot; the rolling mill and the three-dimensional moving platform are arranged on the installation bracket, a fixture is arranged on the moving part of the three-dimensional moving platform, and the first heating furnace is arranged on one side of the installation bracket; the first robot is arranged between the tail of the installation bracket and the second heating furnace, the trimming and punching machine is arranged on one side of the first robot, and the second robot is arranged between the coiling machine and the second heating furnace.

[0005] Further, it further includes a straightening machine, the straightening machine is arranged at the tail of the installation bracket, and the straightening machine is located between the rolling mill and the first robot.

[0006] Further, it further includes a loading conveyor line, the loading conveyor line is arranged at the head of the installation bracket, and the loading conveyor line is used to convey the steel to be processed.

[0007] Further, it further includes a cooling bed; along the conveying direction of the steel processing, the loading conveyor line, the installation bracket, the first machine, the second heating furnace, the second robot, and the cooling bed are arranged in sequence.

[0009] The present invention also provides a processing method for the above steel rolling line, including:

[0010] Step 1: The three-dimensional moving platform places the steel to be processed into the first heating furnace for heating through a fixture;

[0011] Step 2: After the first heating furnace heats the steel to the set temperature, the three-dimensional moving platform takes out the steel from the first heating furnace through a fixture and places it on the rolling mill for rolling;

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the following drawings are some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0019] Figure 1 It is a schematic structural diagram of an embodiment of the steel rolling line of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, the steel rolling line of this embodiment includes an installation bracket 1, a first heating furnace 21, a second heating furnace 22, a rolling mill 3, a trimming and punching machine 4, a coiler 5, a three-dimensional moving platform 6, a first robot 71, and a second robot 72; the rolling mill 3 and the three-dimensional moving platform 6 are arranged on the installation bracket, a fixture is arranged on the moving part of the three-dimensional moving platform 6, and the first heating furnace 21 is arranged on one side of the installation bracket 1; the first robot 71 is arranged between the tail of the installation bracket 1 and the second heating furnace 22, the trimming and punching machine 4 is arranged on one side of the first robot 71, and the second robot 72 is arranged between the coiler 5 and the second heating furnace 22.

[0022] Specifically, the steel to be processed is first placed into the first heating furnace 21 through the three-dimensional moving platform 6 to heat the steel to the required temperature by the first heating furnace 21. Then, the three-dimensional moving platform 6 drives the steel to move along the processing and conveying direction of the steel to the rolling mill 3 for processing, so as to roll the steel by the rolling mill 3.

[0023] After the rolling process, since the steel will deform under stress, the steel rolling line further includes a straightening machine 8. The straightening machine 8 is arranged at the tail of the installation bracket 1 and is located between the rolling mill 3 and the first robot 71. Specifically, the three-dimensional moving platform 6 clamps the rolled steel and continues to move and place it on the straightening machine 8 for processing.

[0024] After the steel is processed by the straightening machine 8, the steel is clamped by the first robot 71 and turned and moved to the trimming and punching machine 4 on one side for machining. The trimming and punching machine 4 can punch the excess material of the steel, and at the same time, can also punch holes in the steel.

[0025] After the machining of the steel is completed by the trimming and punching machine 4, the first robot 71 picks up the steel and turns and moves it into the second heating furnace 22. The steel will be reheated in the second heating furnace 22. Since the steel moves quickly through the three-dimensional moving platform 6 and the first robot 71 during the previous machining operation, the temperature of the steel is still relatively high when it enters the second heating furnace 22. In this way, by reducing the amount of heat loss caused during the handling of the steel, the temperature of the steel is maintained at a relatively high level, thereby reducing the heating time of the steel in the second heating furnace 22 and achieving a reduction in processing energy consumption.

[0026] After the steel is heated to the set temperature in the second heating furnace 22, the second robot 72 takes out the steel from the second heating furnace 22 and transports it to the coiler 5 on one side for coiling operation.

[0027] Furthermore, in order to better achieve fully automated operation, the steel rolling line of this embodiment further includes a loading conveyor 9, which is arranged at the head of the mounting bracket 1. The loading conveyor 9 is used to convey the steel to be processed. Specifically, the loading conveyor 8 can automatically convey the steel to be processed to the three-dimensional moving platform 6 to achieve automatic loading.

[0028] Even further, the steel rolling line of this embodiment further includes a cooling bed 10. Specifically, after the coiling operation of the steel is completed in the coiler 5, the second robot 72 can carry the coiled steel to the cooling bed 10 for cooling.

[0029] Regarding the layout positions of the various components in the steel rolling line of this embodiment, along the steel processing and conveying direction, the loading conveyor 9, the mounting bracket 1, the first machine, the second heating furnace 22, the second robot 72, and the cooling bed 10 are arranged in sequence. Correspondingly, the rolling mill 3 is arranged on one side of the three-dimensional moving platform 6, the trimming and punching machine 4 is arranged on one side of the first robot 71, and the coiler 5 is arranged on one side of the second robot 72. Among them, for the specific structural forms of the rolling mill 3, the trimming and punching machine 4, the coiler 5, and the loading conveyor 9, reference can be made to the equipment configuration in the conventional steel rolling line, and no further elaboration and limitation will be made here. In addition, in order to improve the heating efficiency, the first heating furnace 21 and the second heating furnace 22 are electric heating furnaces.

[0030] The present invention also provides a processing method for the above steel rolling line, including:

[0031] Step 1: The three-dimensional moving platform places the steel to be processed into the first heating furnace for heating through a fixture;

[0032] Step 2: After the first heating furnace heats the steel to the set temperature, the three-dimensional moving platform takes out the steel from the first heating furnace through a fixture and places it on the rolling mill for rolling;

[0033] Step 3: The three-dimensional moving platform places the rolled steel on the straightening machine through a fixture, and the straightening machine straightens the steel.

[0034] Step 4: The first robot transports the straightened steel to the edge trimming and punching machine for edge trimming and punching.

[0035] Step 5: The first robot places the steel after edge trimming and punching into the second heating furnace for heating.

[0036] Step 6: After the second heating furnace heats the steel to the set temperature, the second robot takes out the steel from the second heating furnace and places it on the ear rolling machine for ear rolling.

[0037] Step 7: The second robot places the steel after ear rolling on the cooling bed for cooling.

[0038] Compared with the prior art, the advantages and positive effects of the present invention are as follows: The steel rolling line provided by the present invention realizes online continuous operation by using a three-dimensional moving platform and a robot to transport steel. On the one hand, it can reduce labor and the labor intensity of workers. On the other hand, it can effectively shorten the time required for transportation between different workstations. In this way, when ear rolling operation is carried out, the temperature of the steel is still relatively high, and thus only a short heating time in the second heating furnace is required to meet the requirements of ear rolling, effectively reducing energy consumption.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
