Description

Technical Field

[0001] The utility model relates to the technical field of steel wire cooling, in particular to a quenching oil tank. Background Art

[0002] Spring steel wire quenching is an important heat treatment process to improve its elasticity, strength and wear resistance. Quenching can ensure the formation of martensitic structure inside the steel wire, thereby obtaining high hardness and high strength. Steel wires with smaller diameters are generally cooled by oil cooling in the quenching oil tank. When the steel wire is in motion, it can only contact the quenching oil around it. It is difficult for the steel wire to contact more quenching oil with lower temperature, which will affect the quenching effect and lead to low cooling efficiency of the steel wire. Moreover, before the steel wire enters the quenching process, oxide scale may form on the surface of the steel wire for the heat treatment process. When the steel wire is immersed in the quenching oil, the oxide scale may fall off and enter the quenching oil. After the quenching oil tank has been used for a long time, impurities (oxide scale) will be deposited at the bottom of the quenching oil tank, which is not easy to clean. Quenching oil containing impurities will affect the quenching quality of the steel wire. Summary of the invention

The pump body 4 is fixed on the right side surface of the outside of the tank body 1, and the input end of the pump body 4 is connected to the tank body 1 on the lower side of the transverse plate 2 through a connecting pipe 1 8, and the output end is connected to the right part of the quenching chamber through a connecting pipe 2 9; the cleaning part includes a fixed partition net 10 and a movable partition net, and the fixed partition net 10 is connected between the left end of the bottom surface of the transverse plate 2 and the inner bottom of the tank body 1, and a movable partition net is provided in the tank body 1 on the left side of the fixed partition net 10.

[0022] The top surface of the transverse plate 2 is flush with the upper end of the left side plate of the tank body 1 ; the upper end of the baffle plate 3 is inclined to the left, and the upper end of the baffle plate 3 is lower than the upper ends of the front and rear side plates of the tank body 1 .

[0023] The left side of the baffle 3 is connected with a vertical connecting plate 11, which is a rectangular plate. A bolt 12 is installed on the connecting plate 11. The free end of the bolt 12 passes through the connecting plate 11, and the free end of the bolt 12 extends into the horizontal plate 2 and is threadedly connected to the left part of the horizontal plate 2.

[0024] The front and rear ends of the fixed partition net 10 are fixedly connected to the front and rear inner surfaces of the trough body 1; the movable partition net includes a frame body 13 and a vertical rod 15, the frame body 13 is a rectangular frame, and a sheet net 14 is arranged in the frame body 13. The trough body 1 on the left side of the fixed partition net 10 is a collecting chamber, and the outer side surface of the frame body 13 is in upward and downward sliding contact with the side surface of the collecting chamber. The top surface of the frame body 13 is fixed with a vertical rod 15, and the vertical rod 15 is a round rod.

[0025] The free end of the connecting pipe 2 9 passes through the right side plate of the tank body 1 on the lower side of the horizontal plate 2 to the left, bends upward and passes through the right part of the horizontal plate 2. The liquid level of the quenching oil 5 is higher than the connecting pipe 1 8 and the connecting end of the tank body 1 and lower than the horizontal plate 2.

[0026] A movable rod 16 is provided in the trough body 1 on the right side of the fixed partition net 10. The movable rod 16 is a rectangular rod. The upper and lower ends of the movable rod 16 slide in contact with the bottom surface of the horizontal plate 2 and the bottom surface of the trough body 1 respectively. A screw 17 is threadedly connected to the movable rod 16. The rear end of the screw 17 is rotatably connected to the rear side plate of the trough body 1, and the front end of the screw 17 penetrates the front side plate of the trough body 1 and is connected to the output end of the motor 20 fixed to the trough body 1. The left side of the movable rod 16 is provided with bristles 18 whose ends contact the right side of the fixed partition net 10. The motor 20 model selected for the utility model is F5D200-24GU-18S, and the output shaft of the motor can be rotated forward and reverse.

[0027] When in use, a plurality of steel wires pass through the relative through hole 1 6 and through hole 2 7, and the plurality of steel wires move from left to right. The pump body 4 is started, and the quenching oil 5 at the lower part of the tank body 1 enters the pump body 4 through the connecting pipe 1 8, and then enters the tank body 1 on the upper side of the transverse plate 2 (i.e., the quenching chamber) through the connecting pipe 2 9. Due to the obstruction of the baffle 3, as the quenching oil 5 increases in the quenching chamber, the liquid level of the quenching oil 5 in the quenching chamber rises and submerges the plurality of moving steel wires, quenching the steel wires. As the quenching oil 5 flows in the quenching chamber, the quenching oil 5 flows in the quenching chamber, and the quenching oil 5 flows in the quenching chamber. When the liquid level in the fire chamber continues to increase and is higher than the upper end of the baffle 3, the quenching oil 5 overflows from the upper end of the baffle 3 and enters the tank body 1 on the left side of the fixed partition 10 (i.e., the collecting chamber). Therefore, when the quenching oil 5 in the quenching chamber quenches the steel wire moving to the right, the quenching oil 5 in the quenching chamber also moves to the left and overflows from the upper end of the baffle 3. The relative movement of the steel wire and the quenching oil 5 can make the steel wire contact with more quenching oil 5 at a lower temperature, thereby improving the cooling efficiency of the steel wire.

[0028] Moreover, impurities such as scale dropped during the quenching process of the steel wire, especially impurities floating on the quenching oil 5, can enter the collecting chamber along with the quenching oil 5, be blocked by the fixed partition 10, and stay in the collecting chamber. The filtered quenching oil 5 enters the tank 1 on the right side of the fixed partition 10 through the fixed partition 10, and is driven by the pump body 4 to enter the quenching chamber again, thereby realizing the circulation of the quenching oil, and preventing the impurities floating in the quenching oil 5 from affecting the quenching of the steel wire. The motor 20 drives the screw 17 to rotate counterclockwise (the counterclockwise rotation of the screw is Figure 2 ), driving the movable rod 16 to move backward, and the screw rod 17 rotates clockwise (the clockwise rotation of the screw rod is Figure 2 The movable rod 16 is driven to move forward, and the bristles 18 on the movable rod 16 clean the impurities on the fixed partition 10 to prevent the impurities in the collection chamber from clogging the mesh of the fixed partition 10, thereby ensuring that the quenching oil 5 in the tank body 1 flows smoothly;

[0029] After the quenching of the steel wire is completed, when it is necessary to clean the impurities in the tank body 1, first remove the lower baffle 3, drive the pump body 4 to make the quenching oil 5 at the bottom of the tank body 1 enter the upper side of the horizontal plate 2, and the quenching oil 5 on the upper side of the horizontal plate 2 flows to the left into the collecting chamber. When the quenching oil 5 on the upper side of the horizontal plate moves to the left, it can flush and drive the impurities deposited on the upper side of the horizontal plate 2, so that the deposited impurities enter the collecting chamber. After the impurities on the upper side of the horizontal plate 2 are cleaned, the pump body 4 stops moving, and the vertical rod 15 is used to pull the movable partition upward. When the movable partition moves upward, the quenching oil 5 flows into the tank body 1 through the sheet net 14 on the movable partition, and the movable partition can drive the impurities in the collecting chamber to be discharged through the opening at the upper end of the collecting chamber.

Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
