Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, in particular to a powder metallurgy sintering oil-immersing device. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Among them, the subsequent treatment of the product after sintering can be carried out in a variety of ways according to different product requirements, such as finishing, oil immersion, machining, heat treatment and electroplating. Oil immersion is an important process to improve the strength, hardness, wear resistance, fatigue resistance and toughness of the product.

[0003] Existing powder metallurgy sintered products are usually directly placed in oil for oil immersion treatment. After the treatment, the powder metallurgy products need to be taken out from the oil storage tank. It is very troublesome to take the products out of the oil storage tank after the oil immersion treatment is completed. At the same time, the powder metallurgy sintered products are usually fixed during the oil immersion treatment process, which will cause the powder metallurgy sintered products to be unable to fully contact with the oil, thereby reducing the working efficiency of the oil immersion and affecting the oil immersion effect. Utility Model Content

[0004] The utility model aims to provide a powder metallurgy sintering oil-immersion device, which can improve the oil-immersion efficiency and the oil-immersion effect and facilitate the removal of the oil-immersed product.

[0029] Through the cooperation of the driving member, the first tooth plate 3, the gear 5 and the second tooth plate 4, the driving member drives the first tooth plate 3 to slide on the oil immersion rack 2, the first tooth plate 3 drives the gear 5 to rotate, and the gear 5 drives the second tooth plate 4 to slide on the oil immersion rack 2, so that the first tooth plate 3 and the second tooth plate 4 can reciprocate on the oil immersion rack 2, and then the material loading box 11 on the first tooth plate 3 and the second tooth plate 4 can be repeatedly immersed in the oil immersion box 1. The raw materials will move in the process of repeatedly entering the oil immersion box 1, so that the raw materials can be more fully in contact with the oil, effectively improving the oil immersion effect and oil immersion efficiency. The material loading box 11 can be detachably installed on the first tooth plate 3 and the second tooth plate 4. After the oil immersion is completed, the material loading box 11 can be removed from the first tooth plate 3 and the second tooth plate 4 to facilitate the subsequent processing of the oil-immersed products and improve the product processing speed. The material loading box 11 is installed on the first tooth plate 3 and the second tooth plate 4 respectively, and different raw materials can be immersed in oil according to needs during use, which is more practical.

[0030] In this embodiment, the driving member includes a limit plate 6, a rocker arm 8 and a motor 9. The limit plate 6 is fixedly mounted on the first tooth plate 3. A limit slot 7 is provided on the limit plate 6. One end of the rocker arm 8 is movably mounted in the limit slot 7. The other end of the rocker arm 8 is fixedly connected to the output end of the motor 9. The motor 9 starts to drive the rocker arm 8 to rotate. The rotation of the rocker arm 8 makes one end located in the limit slot 7 move in the limit slot 7, so that the limit plate 6 moves up and down in the vertical direction. The limit plate 6 drives the first tooth plate 3 to move up and down in the vertical direction. The movement of the first tooth plate 3 drives the gear 5 to rotate. The rotation of the gear 5 drives the second tooth plate 4 to move up and down in the vertical direction, so that the loading box 11 on the first tooth plate 3 and the second tooth plate 4 repeatedly enters and exits the oil immersion box 1, thereby improving the oil immersion effect. Among them, a support frame 10 is provided on one side of the oil immersion frame 2. The support frame 10 is located directly above the oil immersion box 1. The motor 9 is fixed to the support frame 10 through a connecting member.

[0031] In this embodiment, a slide groove 16 with an arc-shaped cross section is provided on the oil immersion rack 2, and sliders 17 are provided at both ends of the first tooth plate 3 and the second tooth plate 4, and the sliders 17 are adapted to the slide groove 16. The bottom of the slider 17 is set to a hemispherical surface, and the diameter of the hemispherical surface is the same as the diameter of the slide groove 16, so that the slider 17 can slide in the slide groove 16 more smoothly, and it is more convenient for the first tooth plate 3 and the second tooth plate 4 to move up and down in the vertical direction.

[0032] In this embodiment, vertical plates 12 are provided at both ends of the material loading box 11, through holes are provided on the vertical plates 12, fixing rods 14 are provided on the first tooth plate 3 and the second tooth plate 4, the material loading box 11 is sleeved on the fixing rods 14 through the through holes, and a plurality of oil immersion holes 13 are provided on the side walls and the bottom of the material loading box 11. After the vertical plates 12 on the material loading box 11 are sleeved on the fixing rods 14 through the through holes, a nut 15 is installed at one end of the fixing rod 14 away from the oil immersion rack 2, and the nut 15 is threadedly connected to the fixing rod 14. In this way, the material loading box 11 can be prevented from slipping off the fixing rod 14 during the process of repeatedly entering and exiting the oil immersion box 1, thereby improving the safety of the material loading box 11, and can also facilitate the installation and removal of the material loading box 11, further speeding up the product processing speed. When the material loading box 11 enters the oil immersion box 1, the oil in the oil immersion box 1 enters the material loading box 11 from the oil immersion holes 13 at the bottom and side walls of the material loading box 11, which can speed up the contact speed between the product in the material loading box 11 and the oil, and improve the oil immersion efficiency. At the same time, the oil enters from the surroundings and bottom of the material loading box 11, which can impact the product in the material loading box 11, increase the amount of oil contact per unit time, increase the oil immersion speed, make the product contact with the oil more fully, and make the oil immersion effect better. Among them, the diameter of the oil immersion hole 13 is smaller than the particle size of the product.

[0033] In this embodiment, a filter screen 18 is provided in the oil immersion tank 1, and a spring 19 is provided on the inner bottom surface of the oil immersion tank 1, and the filter screen 18 is placed on the spring 19. In this way, when the material loading box 11 enters the oil immersion tank 1, a certain pressure can be applied to the filter screen 18, and the spring 19 is compressed. When the material loading box 11 leaves the oil immersion tank 1, the filter screen 18 shakes up and down under the action of the spring 19, and the oil in the oil immersion tank 1 can be stirred to prevent oil precipitation. At the same time, the filter screen 18 can also filter the oil, which is convenient for subsequent oil processing.

[0034] In this embodiment, a cylinder 20 is provided at the bottom of the oil immersion tank 1, and a telescopic member is provided at the bottom of the filter 18.

The piston rod of the cylinder 20 passes through the oil immersion tank 1 and is connected to the bottom of the cylinder 22. The telescopic rod 21 and the cylinder 22 are provided. When the material loading box 11 applies a certain pressure to the filter 18, the spring 19 is compressed, and the telescopic rod 21 slides downward in the cylinder 22. When the material loading box 11 leaves the filter 18, the spring 19 returns to its original state, and the telescopic rod 21 slides upward in the cylinder 22. Then, under the action of the cylinder 20, the filter 18 is extended out of the oil immersion tank 1, so as to facilitate the cleaning of impurities on the filter 18 and reduce the difficulty of cleaning the oil immersion tank 1.

[0035] The working principle of a powder metallurgy sintering oil-immersed device is: the initial state is as follows: Figure 1 As shown, put the product into the loading box 11, start the belt motor 9, the motor 9 drives the rocker arm 8 to rotate, so that the other end of the rocker arm 8 moves in the limit groove 7, so that the limit plate 6 moves upward in the vertical direction, the limit plate 6 drives the first tooth plate 3 to move upward, the first tooth plate 3 drives the gear 5 to rotate, the rotation of the gear 5 drives the second tooth plate 4 to move downward, and the loading box 11 on the second tooth plate 4 enters the oil immersion tank 1 (the state is as shown in FIG. Figure 3 As shown), the oil in the oil immersion tank 1 enters the loading box 11 from the oil immersion hole 13 to immerse the product in oil, the rocker arm 8 continues to rotate, the limit plate 6 moves downward in the vertical direction, the limit plate 6 drives the first tooth plate 3 to move downward, the first tooth plate 3 drives the gear 5 to rotate, the rotation of the gear 5 drives the second tooth plate 4 to move upward, and the loading box 11 on the first tooth plate 3 enters the oil immersion tank 1 (the state is as shown in FIG.
