[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Example

[0034] See also Figures 1 to 10 In an embodiment of the present invention, a heat treatment equipment for forging processing includes a processing seat 1, support plates 4 are symmetrically installed on both sides of the upper end of the processing seat 1, support rollers 5 are rotatably installed between the support plates 4, support belts 6 are installed between the outer sides of the support rollers 5, and a plurality of placement rings 7 are evenly installed on the support belt 6, and a transport mechanism for driving the support belt 6 to rotate is also provided on the processing seat 1, a support frame 2 is symmetrically installed on the processing seat 1, an L-shaped plate 40 is fixedly installed downward on the upper end of the support frame 2, a rotating cylinder 34 is rotatably installed between the L-shaped plate 40 and the support frame 2, a processing shaft 21 arranged in a vertical direction is installed inside the rotating cylinder 34 through a rotating portion, a heating furnace chamber 19 is fixedly installed at the bottom of the processing shaft 21, a high-frequency heating coil 22 is installed inside the heating furnace chamber 19, a high-frequency controller 20 is installed on the outer wall of the heating furnace chamber 19, and a driving module for controlling the movement of the heating furnace chamber 19 is also provided on the support frame 2.

[0035] When the heat treatment equipment in this embodiment is working, the forging to be heat treated is first placed inside the placement ring 7 located on the support belt 6, and then the drive module and the transport mechanism are started, so that the forging on the support belt 6 intermittently moves to the corresponding position on the lower side of the heating furnace chamber 19, and then under the action of the drive module, the heating furnace chamber 19 moves to the outside of the entire forging, and then under the cooperation of the high-frequency controller 20 and the high-frequency heating coil 22, the forging is quickly heated, and finally the flow heat treatment needs of a large number of forgings are met. During the entire heat treatment process, there is no need for the staff to take and place the forgings from the heating furnace chamber 19, which further improves the reliability of the heat treatment equipment.

[0036] In order to realize intermittent movement of the forgings on the support belt 6, in this embodiment, the transport mechanism includes a rotating shaft 14 rotatably mounted on one of the support plates 4, a rotating plate 15 is fixedly mounted on the rotating shaft 14, a rotating ring 18 is fixedly mounted at the end edge of the rotating plate 15, a rotating bar 16 is fixedly mounted at the side wall of the rotating plate 15, a rotating column 17 is fixedly mounted at the end of the rotating bar 16, and the transport mechanism also includes a toggle assembly.

[0037] Among them, the toggle assembly includes a toggle plate 11 coaxially fixedly connected to the support roller 5, and a plurality of toggle straight grooves 12 are arranged on the outer wall of the toggle plate 11. Toggle arc grooves 13 are alternately arranged at the edge of the toggle plate 11 between the toggle straight grooves 12. The toggle straight grooves 12 are in contact and cooperate with the rotating column 17, and the toggle arc grooves 13 are in contact and cooperate with the rotating ring 18.

[0038] The working principle of the above-mentioned conveying mechanism is: during the continuous rotation of the rotating shaft 14, the rotating plate 15 will cause the rotating bar 16 and the rotating ring 18 to move synchronously. When the rotating column 17 located on the rotating bar 16 moves to the inside of the toggle straight groove 12, it will drive the entire toggle disk 11 to rotate 90°, so that the supporting roller 5 at the corresponding position drives the supporting belt 6 to move a certain distance, and then the placing ring 7 is intermittently moved to the bottom area of ​​the heating furnace chamber 19 in sequence. When the rotating ring 18 moves to the position of the toggle arc groove 13, the movement of the entire toggle disk 11 will stop and remain for a certain period of time. During this time, the heating furnace chamber 19 just moves to the outside of the forging, and the forging at this position is quickly heated to achieve the purpose of heat treatment.

[0039] In order to coordinate the intermittent movement time of the support belt 6 so that the heating furnace chamber 19 can reciprocate up and down at the corresponding forging position, in this embodiment, the driving module includes a lifting mechanism for driving the heating furnace chamber 19 to move up and down, and the lifting mechanism includes a limit plate 3 fixed at the upper end position of the support frame 2, and a limit shaft 10 is rotatably installed on the limit plate 3. A limit arm 25 is fixedly installed at the end of the limit shaft 10, and a lifting column 26 is fixedly installed on the limit arm 25. The lifting mechanism also includes a lifting assembly.

[0040] The lifting assembly includes a lifting plate 28 rotatably mounted on the top of the processing shaft 21 , a lifting groove ring 27 is fixedly mounted on the upper end of the lifting plate 28 , and a lifting column 26 is slidably mounted inside the lifting groove ring 27 .

[0041] The working principle of the lifting mechanism is as follows: during the movement of the limit shaft 10, the limit arm 25 allows the entire lifting column 26 to slide along the inside of the lifting groove ring 27, and finally, with the cooperation of the lifting plate 28, the processing shaft 21 drives the heating furnace chamber 19 to move to the corresponding position. In order to cooperate with the gap movement process of the support belt 6, we need to set the processing shaft 21 to intermittent up and down reciprocating motion. Therefore, in this embodiment, the lifting groove ring 27 is designed to be composed of a semicircular groove and a linear groove at both ends of the semicircular groove. When the lifting column 26 is located inside the semicircular groove, the up and down position of the entire processing shaft 21 does not change, and when the lifting column 26 is located inside the linear groove, the up and down position of the entire processing shaft 21 changes, and finally drives the heating furnace chamber 19 to move up and down.

[0042] In order to further ensure the heat treatment quality of the forgings, the heating furnace chamber 19 can rotate horizontally back and forth during the heat treatment process. In this embodiment, the driving module also includes a rotating mechanism for the rotational movement of the heating furnace chamber 19, and the rotating mechanism includes a rotating roller 33 fixed on a rotating cylinder 34, and rotating plates 37 are symmetrically installed at the upper and lower ends of the rotating roller 33, and rotating grooves 38 are symmetrically arranged at the edge of the rotating plate 37. The side wall of the rotating roller 33 is provided with cross-arranged positioning grooves 36, and the rotating mechanism also includes a rotating component.

[0043] Among them, the rotating assembly includes a fixed plate 24 fixed on the L-shaped plate 40, a rotating shaft 23 is rotatably installed on the fixed plate 24, a rotating block 29 is fixedly installed on the end of the rotating shaft 23, a locking rod 31 is symmetrically installed on the side wall of the rotating block 29, and a locking plate 32 is fixedly installed on the end of the locking rod 31. The side wall of the rotating block 29 is also symmetrically installed with a locking column 30 that is perpendicular to the locking rod 31. The locking column 30 is in contact with the locking groove 36, and the locking plate 32 is in contact with the rotating groove 38.

[0044] The working principle of the above-mentioned rotating mechanism is: during the continuous rotation of the rotating shaft 23, the locking column 30 and the locking plate 32 on the locking rod 31 rotate synchronously through the cooperation of the rotating block 29. When the locking column 30 moves into the locking groove 36, the rotating roller 33 will rotate 180°, and when the locking plate 32 moves into the rotating groove 38, the entire rotating roller 33 will not continue to rotate due to inertia, thereby ensuring the reliability of the movement of the rotating roller 33. After that, the locking column 30 continues to rotate. Since the locking groove 36 is composed of two arc grooves that intersect each other, the rotating roller 33 will rotate 180° in the reverse direction, thereby realizing the intermittent reciprocating periodic rotation of the heating furnace chamber 19.

[0045] It should be pointed out that in this embodiment, the movements of the lifting mechanism and the rotating mechanism are coordinated with each other. Through the debugging and installation of the components, it is ensured that when the processing axis 21 is located at the bottom position, the heating furnace chamber 19 will rotate 180°, and then the heating furnace chamber 19 will rotate when it completely covers the outside of the forging, thereby fully ensuring the heat treatment quality of the forging.

[0046] In order to ensure the power input of the driving module, in this embodiment, a processing motor 39 is also installed on the fixing plate 24, and the output end of the processing motor 39 is connected to the rotating shaft 23, and the rotating shaft 23 and the limiting shaft 10 are connected to each other through the pulley assembly b9. Through the above-mentioned structure, the lifting mechanism and the rotating mechanism in the driving module can work synchronously.

[0047] In addition, in order to ensure that the rotational movement and lifting movement of the processing shaft 21 do not interfere with each other, in this embodiment, the rotating part includes a contact groove arranged inside the rotating cylinder 34 and a contact strip 35 symmetrically fixed on the outer wall of the processing shaft 21, and the contact strip 35 is slidably arranged inside the contact groove. Example

[0048] In addition, in order to further reduce the operating cost of the heat treatment equipment, the present invention also provides another embodiment, which is different from the above embodiment in that the limit shaft 10 and the rotating shaft 14 are connected to each other through a pulley assembly a8. Through the connection of the pulley assembly a8, the torque of the processing motor 39 can be synchronously transmitted to the rotating shaft 14, and finally drive the transport mechanism to operate.

[0049] In summary, during the heat treatment of forgings, the staff only needs to start the processing motor 39, and then stand on the feeding end of the support belt 6. When the support belt 6 stops moving, the staff can continuously put the forgings to be heat treated into the placement ring 7 on the support belt 6. Then, with the cooperation of the driving module, the heating furnace chamber 19 can intermittently move downward and intermittently rotate, thereby effectively heat treating the forgings. The entire heat treatment process is quick and convenient, and is worthy of promotion and use.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
