Description

Technical Field

[0001] This utility model belongs to the field of heat treatment technology, and in particular relates to a heat treatment equipment for quenching steel balls. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which the chemical composition and structure of a metal material are changed on its surface or inside by means of heating, holding, and cooling in a solid state, so as to obtain the desired properties.

[0003] Traditional heat treatment of steel balls often involves directly quenching them. However, this method results in uneven quenching effects. During the quenching process, the internal temperature and cooling rate of the steel ball will vary at different stages of entering the quenching tank. Steel balls that enter the quenching tank later will affect the quenching effect. Utility Model Content

[0004] The technical problem to be solved by this invention is to make the medium evenly contact and act on the surface of the steel ball, change the movement trajectory of the steel ball as it enters the quenching tank, and increase the fluidity of the medium.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a steel ball quenching heat treatment equipment, including a box body, the box body being a rectangular cavity with an open top, and further including a flipping plate, a lifting and flipping mechanism, and a pushing component. One end of the flipping plate is hinged to the upper side wall of the box body, the lifting and flipping mechanism is located on the upper surface of the box body away from the hinge point of the flipping plate, the other end of the flipping plate is connected to the lifting and flipping mechanism via a steel wire rope, and the pushing component is movably located at the bottom of the box body.

[0006] Furthermore, the flip plate is J-shaped, and protective nets are fixedly connected to both sides of the flip plate. The protective nets are symmetrically distributed, and a storage cavity is formed between the symmetrical protective nets and the flip plate. The interior of the flip plate has strip grooves, which are evenly spaced along the horizontal direction of the flip plate.

[0007] Furthermore, the lifting and flipping mechanism includes a support frame, a rotary motor, a rotating shaft, limiting wheels, and a limiting assembly. The support frame is fixedly connected to the upper surface of the housing and is arranged in an n-shape. The rotating shaft is rotatably disposed between the opposite inner sidewalls of the support frame. The rotary motor is installed on one side of the support frame, and the output end of the rotary motor is fixedly connected to one end of the rotating shaft. The limiting wheels are fixedly connected to the outer sidewall of the rotating shaft and are symmetrically distributed. The limiting assembly is disposed on the upper part of the support frame. A steel wire rope is connected between the rotating shaft and the end of the flipping plate away from the hinge point.

[0008] Furthermore, the limiting component includes a cylinder and a locking plate. The cylinder is installed on the upper wall of the support frame, and the telescopic end of the cylinder slides through the upper wall of the support frame and is slidably disposed within the support frame. The cylinders are symmetrically distributed. The locking plate is fixedly connected to the telescopic end of the cylinder. The locking plate is positioned corresponding to the limiting wheel and is pushed by the telescopic end of the cylinder to make frictional contact with the outer circumference of the limiting wheel. The locking plate is C-shaped.

[0009] Furthermore, the pushing component includes a support spring and a partition plate. One end of the support spring is fixedly connected to the bottom wall of the housing. The support springs are arranged in a symmetrical and equally spaced manner. The partition plate is fixedly connected to the other end of the support spring. The partition plate has through holes, which are arranged in an array with uniform intervals.

[0010] Furthermore, the limiting wheel is a rubber limiting wheel.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows: In order to improve the uniformity of contact between the medium and the steel ball during the quenching process of the steel ball, the lifting and flipping mechanism makes the flipping plate carry the steel ball into the box in an arc trajectory. During the contact with the medium inside the box, the flipping plate uses gravity to press down and push the component, so that the medium at the bottom of the box passes through the partition and pushes the medium upward. When the steel ball is completely submerged in the medium, the medium at the bottom of the box is sprayed upward and mixed with the upper medium, which promotes the quenching of the steel ball and improves the uniformity of contact between the steel ball and the medium.

Detailed Implementation

[0018] like Figure 1-4 As shown, a steel ball quenching heat treatment device includes a box 1 with a rectangular cavity open at the top. It also includes a flipping plate 2, a lifting and flipping mechanism 3, and a pushing assembly 4. One end of the flipping plate 2 is hinged to the upper side wall of the box 1. The lifting and flipping mechanism 3 is located on the upper surface of the box 1 away from the hinge point of the flipping plate 2. The other end of the flipping plate 2 is connected to the lifting and flipping mechanism 3 via a steel wire rope 13. The pushing assembly 4 is movably located at the bottom of the box 1. The box 1 is filled with a medium. A steel ball is placed in the flipping plate 2, and the lifting and flipping mechanism 3 pulls one end of the flipping plate 2, causing it to fall into the medium along an arc. The bottom wall of the flipping plate 2 presses against the pushing assembly 4, causing the medium at the bottom of the box 1 to flow upwards through the pushing assembly 4, improving the uniformity of contact between the medium and the steel ball.

[0019] like Figure 1 and Figure 2 As shown, in order to increase the contact effect between the medium and the steel ball, the flip plate 2 is J-shaped. The two sides of the flip plate 2 are fixedly connected with protective nets 5, which are symmetrically distributed. The symmetrical protective nets 5 and the flip plate 2 form a receiving cavity 6. The inside of the flip plate 2 has strip grooves 7, which are evenly spaced along the horizontal direction of the flip plate 2. The receiving cavity 6 is used to hold the steel ball. The medium enters the receiving cavity 6 through the strip grooves 7 and the protective nets 5 and comes into rapid contact with the steel ball.

[0020] like Figure 1 and Figure 2 As shown, in order to make the flipping plate 2 enter the box 1 along the arc trajectory, the lifting and flipping mechanism 3 includes a support frame 8, a rotary motor 9, a rotating shaft 10, a limiting wheel 11, and a limiting component 12. The support frame 8 is fixedly connected to the upper end face of the box 1 and is arranged in an n-shape. The rotating shaft 10 is rotatably disposed between the opposite inner side walls of the support frame 8. The rotary motor 9 is installed on one side of the support frame 8 and the output end of the rotary motor 9 is fixedly connected to one end of the rotating shaft 10. The limiting wheel 11 is fixedly connected to the outer side wall of the rotating shaft 10 and is symmetrically distributed. The limiting component 12 is disposed on the upper part of the support frame 8. A steel wire rope 13 is connected between the rotating shaft 10 and the end of the flipping plate 2 away from the hinge point. The steel wire rope 13 is connected to one end of the flipping plate 2 and drives the rotary motor 9 to rotate, so that the rotating shaft 10 winds up the steel wire rope 13, and the symmetrical limiting wheel 11 limits and winds up the steel wire rope 13.

[0021] like Figure 1-3 As shown, in order to fix the position of the flip plate 2, the limiting component 12 includes a cylinder 14 and a locking plate 15. The cylinder 14 is installed on the upper wall of the support frame 8. The telescopic end of the cylinder 14 slides through the upper wall of the support frame 8 and is slidably disposed in the support frame 8. The cylinders 14 are symmetrically distributed. The locking plate 15 is fixedly connected to the telescopic end of the cylinder 14. The locking plate 15 is positioned opposite to the limiting wheel 11 and is pushed by the telescopic end of the cylinder 14 to make frictional contact with the outer circumference of the limiting wheel 11. The locking plate 15 is C-shaped. The limiting wheel 11 is a rubber limiting wheel 11. When the flip plate 2 is lifted to a certain height by the wire rope 13, in order to fix the position of the flip plate 2, the cylinder 14 is driven to extend, so that the locking plate 15 fits against the outer circumference of the limiting wheel 11 and presses and fixes the limiting wheel 11.

[0022] like Figure 2 and Figure 3 As shown, in order to promote the flow of the medium inside the housing 1 and enable the medium to contact the surface of the steel ball evenly, the pushing component 4 includes a support spring 16 and a partition 17. One end of the support spring 16 is fixedly connected to the bottom wall of the housing 1. The support springs 16 are arranged in a symmetrical and evenly spaced manner. The partition 17 is fixedly connected to the other end of the support spring 16. The partition 17 has through holes 18, which are arranged in an array with even intervals. When the flip plate 2 rotates downward, the bottom wall of the flip plate 2 presses against the partition 17, the support spring 16 contracts, and the medium below the partition 17 is sprayed upward through the through holes 18, pushing the medium to flow inside the housing 1, so that the medium can fully contact the steel ball and improve the quenching effect of the steel ball.

[0023] In actual use, in the initial state, the flip plate 2 is parallel to the upper port of the box 1, the locking plate 15 is in contact with the limit wheel 11, and the medium is poured into the box 1. Generally, the medium is water or oil. The operator puts the steel ball into the storage cavity 6 inside the flip plate 2, drives the rotary motor 9 to gradually release the steel wire rope 13, and at the same time drives the cylinder 14 to retract, so that the locking plate 15 separates from the limit wheel 11, so that the flip plate 2 flips along the arc trajectory and enters the box 1, so that the steel ball comes into contact with the medium. After the flip plate 2 is completely inside the box 1, the bottom wall of the flip plate 2 presses on the partition 17, the support spring 16 retracts, and the medium below the partition 17 is sprayed upward through the through hole 18, pushing the medium to flow inside the box 1, so that the medium can fully contact the steel ball and improve the quenching effect of the steel ball.
