Description

Technical Field

[0001] The invention relates to the technical field of quenching, in particular to a manganese steel casting quenching device. Background Art

[0002] Quenching is a commonly used metal heat treatment process that aims to improve the metal's hardness, strength, wear resistance and other properties. For manganese steel, the quenching process can significantly improve its hardness and strength, and further enhance its wear and corrosion resistance.

[0003] The existing Chinese patent CN114959209A discloses a quenching treatment device and method for casting processing, which is provided with a spiral blade, and a scraper is driven to rotate by a motor 2, so that the scraper rotates the blades in the bottom end of the cavity 1, and then the spiral blade drives the waste chips and water to move upward. When the spiral blade lifts the waste chips and water to the filter screen, the water will enter the cavity 1 through the filter screen, so that the waste chips continue to rise to the slag discharge pipe and are discharged through the slag discharge pipe, so that the waste chips are easy to clean. During use of the above-mentioned device, the scraper rotates on the inclined bottom surface of cavity one, scraping the waste debris on the bottom surface of cavity one, so that the waste debris enters cavity two. However, since the liquid in cavity one is not discharged, the scraper will cause the liquid inside cavity one to shake during the rotation, causing the waste debris to diffuse in the liquid in cavity one, and the water transported by the spiral blades in cavity two will flow back to cavity one through the filter screen, further enhancing the shaking amplitude of the water, and the waste debris will further diffuse in the liquid, making the device less efficient in cleaning the waste debris in the liquid and having a poor cleaning effect.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1-Figure 4 A manganese steel casting quenching device shown in the figure includes a quenching box 1, on the outside of which are fixedly installed a water inlet pipe 2 and a drain pipe 3, and the water inlet pipe 2 is located on the upper side of the drain pipe 3, and the drain pipe 3 is located inside the quenching box 1. A filter plate 4 is fixedly installed at one end, and also includes a filtering mechanism for filtering out debris in the quenching liquid inside the quenching box 1, and the filtering mechanism is installed inside the quenching box 1; a water-displacing component for displacing the water outside the filtering mechanism, and the water-displacing component is installed on the outside of the filtering mechanism; a driving component for driving the water-displacing component to swing back and forth, and the driving component is installed on the front and rear sides of the quenching box 1.

[0028] The filtering mechanism includes a grid plate 7 that can move left and right inside the quenching box 1. A silicone strip 8 is fixedly embedded on the outer side of the grid plate 7, and the silicone strip 8 is movably fitted with the inner wall of the quenching box 1. The silicone strip 8 is used to enhance the sealing between the grid plate 7 and the inner wall of the quenching box 1. Two connecting seats 9 are fixedly installed on the outer side of the grid plate 7, and the two connecting seats 9 are close to the upper end of the grid plate 7.

[0029] A threaded rod 10 is installed inside the connecting seat 9, and the threaded rod 10 is rotatably connected to the quenching box 1 through a bearing, one end of the threaded rod 10 is fixedly connected to a drive motor 11, and the connection between the drive motor 11 and the quenching box 1 is a fixed connection, and a filter plate 12 is fixedly embedded in the grille hole of the grille plate 7, and the filter plate 12 is used to filter metal debris in the quenching liquid.

[0030] Two symmetrically distributed drainage troughs 5 are fixedly installed at the lower end of the quenching box 1. The inner bottom surface of the drainage trough 5 is inclined. A sewage pipe 6 interconnected with the drainage trough 5 is fixedly embedded at the front end of the drainage trough 5, and the end of the sewage pipe 6 away from the quenching box 1 is fixedly connected to a sewage pump. The sewage pipe 6 is used to discharge the liquid containing metal debris in the quenching box 1, and a solenoid valve is fixedly installed on the sewage pipe 6.

[0031] Working principle: When quenching manganese steel castings, personnel immerse the manganese steel castings in the quenching liquid inside the quenching box 1, and at the same time, the drain pipe 3 discharges the heated quenching liquid inside the quenching box 1, and the water inlet pipe 2 replenishes the quenching liquid with a lower temperature into the quenching box 1. During the quenching process, the surface oxide layer of the manganese steel castings will fall off, and the fallen oxide layer will be mixed in the quenching liquid;

[0032] When it is necessary to clean the metal debris in the quenching liquid, the personnel control the driving motor 11 to run, and the driving motor 11 drives the threaded rod 10 to rotate forward and reversely. During the rotation of the threaded rod 10, the grid plate 7 and the filter plate 12 can be driven to move inside the quenching box 1. During the movement, the filter plate 12 can filter the metal residue in the quenching liquid and concentrate the metal residue on the upper side of the drain trough 5. The clean liquid passes through the filter plate 12 and is located on the other side of the grid plate 7, and the quenching work can continue, so that the cleaning of the quenching liquid is simple and fast, and the cleaning effect is good, which has little impact on the quenching work of batch manganese steel castings.

[0033] Example 2: Please refer to Figure 4-Figure 6 The present embodiment further explains the first embodiment, the water-repelling assembly includes a second grille plate 13 installed on the left and right sides of the grille plate 17, and the two grille plates 13 are staggered, and a plurality of capped pins 14 are fixedly installed on the outer side of the grille plate 17, and a limiting straight groove 15 is provided on the second grille plate 13 corresponding to the capped pins 14, and the capped pins 14 are in sliding contact with the second grille plate 13 through the limiting straight groove 15, and the capped pins 14 are used to prevent the second grille plate 13 from separating from the first grille plate 7, and a plurality of water-repelling plates 16 distributed at equal distances are fixedly installed on the side of the second grille plate 13 away from the first grille plate 7, and a positioning seat 17 and a positioning seat 2 18 are also fixedly installed on the side of the second grille plate 13 away from the first grille plate 7.

[0034] The width of the grille holes on the grille plate 17 is greater than the width of the grille holes on the grille plate 2 13. The positioning seat 17 and the positioning seat 2 18 are close to the upper end of the grille plate 2 13. The positioning seat 3 19 is fixedly installed on the grille plate 17, and the positioning seat 17, the positioning seat 2 18 and the positioning seat 3 19 are located on the same horizontal line. A pin rod 20 is fixedly embedded on the side of the positioning seat 3 19 close to the positioning seat 17, and the pin rod 20 penetrates the positioning seat 17. A spring 1 21 is movably sleeved on the outer side of the pin rod 20, and the two ends of the spring 1 21 are movably abutted against the positioning seat 17 and the positioning seat 3 19 respectively.

[0035] The driving assembly includes a retaining frame 22 fixedly connected to the quenching box 1, and a plurality of grooves 23 distributed at equal distances are provided on the side of the retaining frame 22 close to the grid plate 13, and a push rod 24 is fixedly embedded on the side of the positioning seat 18 close to the retaining frame 22, and a hemispherical portion 25 is provided on the end of the push rod 24 away from the positioning seat 18, and the hemispherical portion 25 is used to reduce the movement resistance of the push rod 24, and the push rod 24 is in sliding contact with the retaining frame 22 through the grooves 23 and the hemispherical portion 25.

[0036] In this embodiment: when the grid plate 13 moves with the grid plate 17, the top rod 24 fixedly installed on the outer side of the grid plate 13 will slide in contact with the retaining frame 22 through the hemispherical portion 25 and the multiple grooves 23, and the driving force of the compression elastic force of the spring 21 can make the grid plate 13 and the multiple water-diverting plates 16 swing back and forth during the left and right movement. The water-diverting plates 16 can cause the water body to shake repeatedly during the back and forth swinging process, especially when the water body on the side where the filter plate 12 filters out metal debris shakes, the metal debris can be diffused in a large range in the liquid, which can effectively prevent the metal debris from accumulating on the outer side of the filter plate 12 and causing the filter plate 12 to be blocked. In addition, the diffusion of the metal debris in the liquid is conducive to the metal debris being completely discharged with the quenching liquid when the solenoid valve of the sewage pipe 6 is opened.

[0037] Example 3: Please refer to Figure 3 , Figure 7 and Figure 8 The present embodiment further explains the first embodiment, the inside of the two retaining frames 22 are fixedly installed with retaining blocks 26, and the two retaining blocks 26 are staggeredly distributed, and the side of the retaining block 26 close to the top rod 24 is respectively provided with a bevel portion 27 and a horizontal portion 28, and a plurality of sealing components equal to the number of filter plates 12 are installed on the grid plate 7 corresponding to the filter plates 12, and the sealing components include two inflatable sealing rings 29 movably embedded in the outer side of the grid plate 7 and symmetrically distributed, and the inflatable sealing rings 29 are in the shape of a rectangular frame.

[0038] The two inflatable sealing rings 29 are both located on the outside of the filter plate 12, a connecting pipe 30 is fixedly installed between the two inflatable sealing rings 29, and the two inflatable sealing rings 29 are interconnected through the connecting pipe 30, a sleeve 31 which is interconnected is fixedly installed on the upper end of the connecting pipe 30, and the sleeve 31 is fixedly embedded in the upper end of the grid plate 7, a push rod 2 32 is movably embedded in the upper end of the sleeve 31, and the push rod 2 32 is located inside the sleeve 31 and fixedly connected to a piston 33 at one end, and the piston 33 moves downward inside the sleeve 31 to inflate the two inflatable sealing rings 29.

[0039] The lower end of the piston 33 is movably abutted against a spring 2 34, and the lower end of the spring 2 34 is movably abutted against a gasket 35, and the gasket 35 is fixedly connected to the sleeve 31, and the upper end of the push rod 2 32 is movably embedded with a ball 36, and the upper end of the quenching box 1 is fixedly installed with two symmetrically distributed baffles 37, and the two baffles 37 are respectively close to the left and right ends of the quenching box 1, and the ends of the two baffles 37 close to each other are both provided with a bevel portion 2 38, and the ball 36 is in rolling contact with the baffle 37 through the bevel portion 2 38, and the ball 36 is used to reduce the friction between the push rod 2 32 and the baffle 37.

[0040] In this embodiment, when the push rod 24 located on the clean liquid side moves to the stopper 26, the hemispherical portion 25 of the push rod 24 will slide against the bevel portion 27 of the stopper 26. During this process, the grid plate 13 located on the clean quenching liquid side moves to block the filter plate 12, and then the grid plate 17 and the push rod 24 continue to move. When the hemispherical portion 25 of the push rod 24 moves against the horizontal portion 28 of the stopper 26, the ball 36 at the upper end of the push rod 32 It will roll along the beveled edge 38 of the baffle 37. Driven by the beveled edge 38 of the baffle 37, the push rod 32 will drive the piston 33 to move downward inside the sleeve 31, squeezing the gas inside the sleeve 31 into the two inflatable sealing rings 29. The inflatable sealing ring 29 on the clean quenching liquid side expands and presses against the grid plate 13, which can block the clean liquid in the quenching box 1 from flowing into the liquid mixed with metal debris, thereby preventing the clean liquid in the quenching box 1 from being discharged;

[0041] When the metal debris mixed by the filter plate 12 is all concentrated on the upper side of the drainage trough 5, the grid plate 7 stops moving, the solenoid valve of the sewage pipe 6 opens, and the sewage pump extracts the quenching liquid mixed with metal debris in the quenching box 1 for treatment. At this time, the water inlet pipe 2 replenishes a certain amount of quenching liquid into the quenching box 1.
