Description

Technical Field

[0001] The utility model relates to the technical field of tool heat treatment auxiliary equipment, in particular to a loading and unloading device for tool heat treatment. Background Art

[0002] Heat treatment refers to a metal heat processing process in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and performance. The cutting tool needs heat treatment because it can significantly improve and enhance the performance of the cutting tool, including hardness, toughness, wear resistance, corrosion resistance, etc., so as to meet different usage requirements. Heat treatment changes the microstructure of steel to achieve the best performance state. Specifically, heat treatment includes four basic processes: annealing, normalizing, quenching and tempering.

[0003] After calcining, the tool is usually required to be taken out of the calcining furnace by the staff and then quenched. Since the tool temperature is high before quenching and part of the quenching medium is easy to boil during quenching, it is easy to cause burns to the staff, which poses certain safety hazards. Therefore, we propose to design a loading and unloading device for tool heat treatment. Utility Model Content

[0014] The utility model realizes mutual cooperation among the clamping mechanism, the turntable, the linear motor and the turning frame. The clamping mechanism facilitates driving the tool to extend into or take out of the calcining furnace. At the same time, the turning frame is used to drive the tool to turn into the quenching pool, so that the worker can perform the quenching process on the tool instead of the worker, which greatly reduces the risk of burns to the worker.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] See also Figure 1-3 The utility model provides a loading and unloading device for tool heat treatment, including a linear motor 1, a slider 2 is fixedly connected to the driving end of the linear motor 1, columns 3 are fixedly connected to both sides of the top of the slider 2, an operation panel 4 is fixedly connected to the outer wall of the column 3, a base 5 is fixedly connected to the top of the column 3, and a motor 6 is fixedly connected to the bottom of the base 5.

[0024] The driving shaft of the motor 6 passes through the base 5 and is fixedly connected to the turntable 7. The other end of the top of the base 5 is connected to the center disk 8 by a bearing. The turntable 7 and the top of the center disk 8 are meshed with a first chain 9. The outer wall of the base 5 is provided with a transmission shaft 10. The outer wall of the base 5 is fixedly connected to a limit ring 12. The transmission shaft 10 is rotatably connected to the limit ring 12, which is convenient for limiting the transmission shaft 10. The top of the transmission shaft 10 and the bottom of the center disk 8 are meshed with a second chain 11.

[0025] In this embodiment, corresponding first sprockets are provided on the top of the turntable 7 and the center disk 8, and the two first sprockets are meshed and connected with the first chain 9. When the turntable 7 rotates, the first chain 9 is used for transmission, so as to drive the center disk 8 to rotate. Compared with the direct transmission between the transmission shaft 10 and the turntable 7, the chain suspension range is smaller, the stroke of the single chain is shorter, and the stability is relatively stronger.

[0026] A second sprocket is provided on the top of the transmission shaft 10 and the bottom of the center disk 8. The two second sprockets are meshed and connected with the second chain 11. When the center disk 8 rotates, the transmission is transmitted through the second chain 11, which is convenient for driving the transmission shaft 10 to rotate. By setting the size sprocket ratio of the first sprocket and the second sprocket on the center disk 8 and the transmission shaft 10, it is convenient to increase the rotation speed of the transmission shaft 10.

[0027] A movable plate 13 is slidably connected to the bottom of the base 5, a driving frame 14 is fixedly connected to one side of the movable plate 13, a flip frame 17 is hingedly connected to the end of the base 5, a rack 15 is fixedly connected to the inner wall of the driving frame 14, a gear 16 is fixedly connected to the bottom of the transmission shaft 10, and the gear 16 is meshed with the rack 15 accordingly. Through the transmission between the gear 16 and the rack 15, the movable plate 13 is driven to slide on the bottom of the base 5 and the supporting position relationship between the bottom of the flip frame 17 is adjusted.

[0028] A clamping mechanism 18 is provided inside the flip frame 17. The clamping mechanism 18 comprises a bottom plate 181 fixedly connected to the inner wall of the flip frame 17, a clamping plate 182 is slidably connected inside the flip frame 17, and an electric push rod 183 is fixedly connected to the top of the clamping plate 182.

[0029] Among them, the movable plate 13 is located at the bottom of the base plate 181 and fits smoothly with its bottom. The movable plate 13 can slide flexibly at the bottom of the base plate 181. When the movable plate 13 is separated from the bottom of the base plate 181, the flip frame 17 can rotate at the end of the base 5, driving the tool clamped in the clamping mechanism 18 to switch the heat treatment position.

[0030] When in use, first place the tool at the end of the clamping mechanism 18, the telescopic end of the electric push rod 183 passes through the clamping plate 182 and is fixedly connected to the bottom plate 181, and the electric push rod 183 drives the clamping plate 182 to slide inside the flip frame 17 to facilitate stable clamping of the tool.

[0031] In this device, the motor 6, the electric push rod 183 and the linear motor 1 are all connected to the external power supply. At the same time, the operating switches of the motor 6, the electric push rod 183 and the linear motor 1 are integrated in the operation panel 4, which is convenient for the staff to control the start and stop of related equipment through the operation panel 4.

[0032] When working, the linear motor 1 is first started to drive the entire device forward, so that the clamping mechanism 18 with the tool clamped is extended into the calcining furnace for calcining. During the normalizing process, the knife is repeatedly heated to the critical temperature several times to stabilize the structure of the steel. During the heating process, the knife body can be pulled back and forth to ensure uniform heating.

[0033] After calcination, start the linear motor 1 to pull it out, start the motor 6 to drive the turntable 7 to rotate, and use the chain drive to drive the center disk 8 and the transmission shaft 10 to rotate. Under the meshing relationship between the gear 16 and the rack 15, drive the movable plate 13 to be pulled out from the bottom of the base plate 181. At this time, after the restriction is lost, the flip frame 17 and the clamping mechanism 18 flip over, which is convenient for driving the tool to flip from a horizontal state to a vertical state.

[0034] During the specific heat treatment operation, a quenching pool is set between the calcining furnace and the slider 2, and the quenching can be directly entered into the quenching pool for quenching during the flipping process. This makes it unnecessary for the staff to hold the hand during the heat treatment normalizing and quenching process, greatly reducing the risk of burns to the staff.

[0035] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
