Description

[0001] DISK PROCESSING LINE

[0002] TECHNICAL FIELD

[0003] The invention relates to a disk processing line for processing workpieces in disk form into soil working disks.

[0004] PRIOR ART

[0005] The heat treatment process in a disk processing line to turn disk-shaped workpieces into soil processing disks usually consists of several main stages. These stages are carried out to increase the strength of the workpiece, to make it resistant to wear and to provide the mechanical properties required for end use. The workpiece is heated to a certain temperature. This temperature range allows the steel to transform into the austenite phase. The austenite phase allows the crystal structure of the steel to be rearranged and its hardness to be increased. After the heating process, the workpiece is cooled rapidly. This process is carried out to ensure the hardening of the workpiece. However, this process can also create internal stresses in the workpiece. For this reason, the workpiece is heated again and the desired surface tolerance is obtained.

[0006] In the disk processing line of the current technique, during the transfer of the disks from the heating unit to the cooling unit and from the cooling unit back to the heating unit, the improper functioning or misalignment of mechanical carrier systems may cause the disks to be scratched, bent, or deformed on their surfaces. In addition, vibrations or sudden shocks encountered during the transfer of the disks in the carrier systems may cause cracks to form on the disks or deterioration in the mechanical properties of the disks.

[0007] Application No. CN105033098A known in the literature relates to the production of disks. The purpose of the invention is to improve the production process of disk brackets having high durability, impact resistance, and wear resistance. The proposed solution involves heating a disk raw material made of manganese-boron steel up to the austenitizing temperature, and then rapidly cooling it in a forming mold. The mold is made of metal alloys with high thermal conductivity and includes cooling water tanks and convex-concave connection parts. However, the invention does not include an automatic heat treatment line fed by robotic arms, and therefore fails to offer a solution to eliminate the disadvantages mentioned above.

[0008] As a result, all the above-mentioned problems have made it imperative to make an innovation in the relevant technical field.

[0009] SUMMARY OF THE INVENTION

[0010] The present invention relates to a disk processing line for eliminating the above- mentioned disadvantages and bringing the new advantages to the relevant technical field.

[0011] An object of the invention is to provide a disk processing line in which surface problems are eliminated.

[0012] Another object of the invention is to provide a disk processing line in which defective products are minimized.

[0013] In order to achieve all the purposes mentioned above and that will emerge from the detailed description below, the present invention is related to a disk processing line for processing workpieces in disk form into soil working disks. Accordingly, its novelty is that it comprises at least one first furnace comprising a conveyor for advancing the workpiece and enabling the workpiece to be heated up to a first temperature;

[0014] It comprises a hot forming unit located in the vicinity of the first furnace, in which the workpiece is subjected to a hot forming process;

[0015] It comprises at least one first robotic arm positioned between the hot forming unit and the first furnace, configured to receive the workpiece from the first furnace and transfer it to the hot forming unit;

[0016] It comprises at least one second furnace located in the vicinity of the hot forming unit, enabling the workpiece to be heated up to a second temperature lower than the first temperature; and it comprises at least one second robotic arm positioned between the second furnace and the hot forming unit, configured to receive the workpiece from the hot forming unit and transfer it to the second furnace. Thus, a disk processing line is obtained in which surface problems are eliminated, the transfer within the line is facilitated, and processing efficiency is increased.

[0017] A possible embodiment of the invention is characterized in that it comprises at least one stopper element that ensures the stopping of the workpiece after it exits the first furnace. Thus, the workpiece coming out of the first furnace can be taken under control.

[0018] Another possible embodiment of the invention is characterized in that it comprises at least one pushing unit that directs the workpiece which has become stationary thanks to the stopper element. Thus, the workpiece is transferred to the first robotic arm.

[0019] Another possible embodiment of the invention is characterized in that it comprises at least one sensor, which is essentially a thermal sensor, that detects the workpiece moved by the said pushing unit. Thus, a command to pick up the workpiece is transmitted to the first robotic arm.

[0020] Another possible embodiment of the invention is characterized in that it comprises at least one safety barrier that surrounds the first furnace, the hot forming unit, and the second furnace, and ensures occupational safety. Thus, occupational safety is ensured in the disk processing line of the invention.

[0023] DETAILED DESCRIPTION OF THE INVENTION

[0024] In this detailed description, the subject of the invention is explained by way of example only for a better understanding of the subject, which shall not create any limiting effect.

[0025] Fig. 1 shows a representative perspective view of at least one disk processing line (10) assembly of the invention. The disk processing line (10) in question is a heat treatment process for transforming workpieces in disk form into soil working disks and generally comprises several main stages. These stages increase the strength of the workpiece, make it resistant to wear, and impart the mechanical properties required for end use.

[0026] The disk processing line (10) which is the subject of the invention comprises at least one first furnace (20). The first furnace (20) is the first section where the workpiece enters to be processed. The disk, which is the cold workpiece, is transmitted to the first furnace (20) via a feeding unit. In a possible embodiment of the invention, a first temperature (21 ) is applied to the workpiece in the first furnace (20). The first temperature (21) is approximately 900 degrees. The first temperature (21) enables the steel to transform into the austenite phase. The austenite phase allows the crystal structure of the steel to be rearranged and its hardness to be increased. At this stage, a controlled atmosphere is provided in the first furnace (20).

[0027] There is at least one conveyor (22) in the first furnace (20). Said conveyor (22) advances the workpiece in the first furnace (20). There is at least one stopper element (23) is located outlet of the first furnace (20). Said stopper element (23) holds the workpiece at the located outlet of the first furnace (20). The workpiece moved by the conveyor (22) hits the stopper element (23) and is fixed. The disk processing line (10) which is the subject of the invention includes at least one pusher unit (24). Said pusher unit (24) provides the movement of the workpiece exiting the first furnace (20) after it is stopped by the stopper element (23), for further processing. The fact that the pusher unit (24) moves the disk which is the workpiece is detected by at least one sensor (25). Said sensor (25) essentially consists of three thermal sensors. The sensor (25) detects that the disk is ready for transfer to the area where hot shaping will be performed, which is another process step.

[0028] The disk processing line (10) which is the subject of the invention comprises at least one first robotic arm (30). Said first robotic arm (30) is connected to the ground by at least one fixed body (not shown in the figures). The first robotic arm (30) can process two different workpieces at the same time by having two different heads. The first robotic arm (30) transfers the disk, which has undergone heat treatment in the first furnace (20), to at least one hot forming unit (40), where the next process step, hot forming, will take place. The first robotic arm (30) connects the hole in the center of the workpiece with the hole in the center of the mold located in the press in the said hot forming unit (40). The workpiece is first shaped in the hot forming unit (40) and then, after being cooled by giving water, it is transmitted to another process.

[0029] After being processed in the hot forming unit (40), the disk is taken by at least one second robotic arm (50). The second robotic arm (50) is connected to the ground by means of a fixed body. The second robotic arm (50) can process two workpieces at the same time as it contains two different heads. The second robotic arm (50) transmits the disk it takes from the hot forming unit (40) to at least a second furnace (60). Hardening occurs in the workpiece discharged from the hot forming unit (40). In order to eliminate the internal stresses that occur as a result of this hardening and to reduce brittleness, the workpiece is subjected to the tempering process in the second furnace (60). Tempering is the process of reheating the workpiece in the second furnace (60) to a second temperature (61) and then slowly cooling it. The second temperature (61) is between 150-500°C.

[0030] The disk exiting the second furnace (60) completes the processing steps in the disk processing line (10). There is at least one safety barrier (70) surrounding all the mechanical components forming the disk processing line (10) of the invention, namely the first furnace (20), the second furnace (60), the hot forming unit (40), the first robotic arm (30), and the second robotic arm (50). The safety barrier (70) has been developed to prevent any work accidents during the process and, in addition, to prevent the processed disk from deforming during the process.

[0031] In line with the described above, the invention works as follows; the workpiece to be transformed into a soil processing disk is transmitted to the first furnace (20) via a feeding unit. The workpiece is subjected to a temperature of 900 degrees in the first furnace (20) and its movement is provided by the conveyor (22) in the first furnace (20). The workpiece exiting the first furnace (20) is stopped by the stopper element (23), then moved by the pushing unit (24), and is transferred to the hot forming unit (40) by the first robotic arm (30) after the sensor (25) with thermal sensors that detects the movement of this pusher unit (24). The cooling process is carried out by giving water in the hot forming unit (40) and thus the surface tension increases. The workpiece processed in the hot forming unit (40) is transmitted to the second furnace (60) by the second robotic arm (50). In the second furnace (60), a second temperature (61) of approximately 150-500 degrees is applied to the disk and the desired surface tolerance is obtained.

[0032] Therefore, a disk processing line (10) is obtained where the heating, hot shaping and tempering processes of the disk to be transformed into a soil processing disk are carried out with high precision, deformation is reduced and efficiency is increased.

[0033] The scope of protection of the invention is specified in the appended claims and cannot be limited to what is described for illustrative purposes in this detailed description. It is clear that a person skilled in the art can produce similar embodiments in the light of what is explained above, without deviating from the main theme of the invention.
