Description

Technical Field

[0001] The utility model relates to the technical field of self - drilling screw production, in particular to a quenching and cooling device for self - drilling screw production. Background Technique

[0002] Self - drilling screws, also known as self - tapping screws or self - drilling self - tapping screws, are a special type of screw with the functions of self - drilling holes and self - tapping threads. For the production of self - drilling screws, quenching and cooling is an important technological step, which is used to change the organizational structure of the screw material and increase its hardness and strength.

[0003] The utility model with the application number CN202120430327.8 discloses a quenching and cooling device for self - drilling screw production. The hoisting mechanism located at the bottom of the overhead crane can drive the self - drilling screw placement cylinder to move back and forth in the cooling pool. At the same time, the reciprocating rotating shaft can drive the self - drilling screw placement cylinder to rotate reciprocally, improving the quenching and cooling effect of the heat treatment of self - drilling screws, making the hardness of self - drilling screws more uniform. The flowing medium plus the moving workpiece can prevent the self - drilling screws from deforming and cracking.

[0004] The above - mentioned device pumps the cooling solution into the cooling coil through a water pump and a water outlet pipe for cooling and temperature reduction. It cannot filter the impurities in the solution. The impurities easily enter the water pump and the pipeline, easily causing blockage of the water pump and the pipeline, and cannot clean the impurities. After the self - drilling screws are cooled, it is necessary to manually disassemble the self - drilling screw placement cylinder and then take out the self - drilling screws in the self - drilling screw placement cylinder. The manual labor intensity is large, it is not convenient for discharging, and the work efficiency is reduced.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0006] The purpose of the utility model is to solve the above problems and design a quenching and cooling device for self - drilling screw production.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0026] The present utility model provides a quenching and cooling device for the production of self-drilling screws as shown in Figures 1-6 Figure 5, which includes a cooling box 1. A filter box 2 is installed at the bottom of the cooling box 1. A fixed bracket 3 is installed on one side of the cooling box 1. A linear slide 4 is installed on the fixed bracket 3. A multi-stage telescopic cylinder 5 is installed at the bottom of the slider of the linear slide 4. A lifting plate 6 is installed at the telescopic end of the multi-stage telescopic cylinder 5. A placement mesh cylinder 7 is installed on the side wall of the lifting plate 6. A U-shaped notch 8 is provided on the upper side wall of the placement mesh cylinder 7. An inclined U-shaped guide plate 9 is installed in the U-shaped notch 8. An inclined disc 10 is provided in the placement mesh cylinder 7. The inclined disc 10 is slidably connected to the inner wall of the placement mesh cylinder 7. A fixed top plate 11 is installed on one side of the lifting plate 6. The fixed top plate 11 is located above the placement mesh cylinder 7. A power push rod 12 is installed on the fixed top plate 11. The telescopic end of the power push rod 12 penetrates downward through the fixed top plate 11. A connecting rod 13 is installed at the telescopic end of the power push rod 12. One end of the connecting rod 13 away from the power push rod 12 is fixedly connected to the inclined disc 10.

[0027] Put the quenched self-drilling screws into the placement mesh cylinder 7. The linear slide 4 starts to work. The sliding of the linear slide 4 drives the multi-stage telescopic cylinder 5, the lifting plate 6 and the placement mesh cylinder 7 to move, and moves the placement mesh cylinder 7 above the cooling tank 1. The multi-stage telescopic cylinder 5 starts to work. The telescopic end of the multi-stage telescopic cylinder 5 extends into the cooling tank 1 through the lifting plate 6 to drive the placement mesh cylinder 7. The self-drilling screws are cooled by the liquid in the cooling tank 1. At the same time, the slider of the linear slide 4 reciprocates, driving the placement mesh cylinder 7 to reciprocate left and right in the cooling tank 1, so that the self-drilling screws can be in full contact with the liquid, improving the cooling effect of the self-drilling screws. After cooling, the placement mesh cylinder 7 is moved out of the cooling tank 1. The operator places the collection box under the inclined U-shaped guide plate 9. The power push rod 12 starts to work. The telescopic end of the power push rod 12 contracts and drives the inclined disc 10 to move upward through the connecting rod 13. The rising of the inclined disc 10 drives the self-drilling screws to rise. When the downward inclined end of the inclined disc 10 is parallel to the inclined U-shaped guide plate 9, the self-drilling screws on the inclined disc 10 move onto the inclined U-shaped guide plate 9 and are discharged under the guiding action of the inclined U-shaped guide plate 9. The inner wall of the placement mesh cylinder 7 is circular, and the self-drilling screws will gather towards the inclined U-shaped guide plate 9, eliminating the need to disassemble the placement mesh cylinder 7 for material removal, reducing the manual labor intensity, facilitating material discharge, and improving work efficiency.

[0029] When the liquid temperature in the cooling tank 1 rises, the electromagnetic valve 15 is opened. The liquid in the cooling tank 1 enters the filter tank 2 through the drain pipe 14. The impurities in the liquid are filtered by the arc-shaped filter screen plate 16 to prevent impurities from blocking the water pump and pipelines. The water pump 18 starts to work, and the filtered solution in the filter tank 2 is pumped out through the water outlet pipe 17 and conveyed into the cooling coil 19. The heat sink 20 and the heat dissipation fans 21 dissipate heat from the solution in the cooling coil 19, improving the cooling and temperature reduction effect of the solution. The cooled solution is conveyed back into the cooling tank 1 for recycling, saving water resources.

[0030] Refer to the attached drawings of the specification Figure 3 , a plurality of water permeable small holes 22 are provided on the inclined disc 10.
