Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to high-hardness flange heat treatment processing equipment. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, the technology related to flange processing is also constantly improving. Flanges are parts that connect shafts to each other and are indispensable components in pipeline design and pipeline installation valves. Quenching is a heat treatment process method that heats the flange blank to above the critical temperature, keeps it warm for a certain period of time, and then cools it at a cooling rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite.

[0003] The flanges currently used are generally high-hardness flanges. The existing heat treatment equipment for high-hardness flange processing, after the flange blank is heat-treated, only relies on the flange blank itself to cool down, the cooling speed is very slow, and it is inconvenient to take and place flange blanks with different apertures. It is necessary to use equipment of different specifications to take and place flange blanks with different apertures, which is inconvenient to operate and is not conducive to flange processing. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the existing heat treatment equipment for high hardness flange processing, after the flange blank is heat treated, only relies on the flange blank itself to cool down, the cooling speed is very slow, and it is inconvenient to take and place flange blanks with different apertures. It is necessary to use equipment of different specifications to take and place flange blanks with different apertures, which is inconvenient to operate and is not conducive to the processing of the flange. A high hardness flange heat treatment processing equipment is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-hardness flange heat treatment processing equipment includes a support platform and a bracket fixedly installed on the support platform, a reciprocating screw is rotatably installed on the bracket, a slider is threadedly connected to the reciprocating screw, a hydraulic cylinder is fixedly installed on the bottom of the slider, a cross is fixedly connected to the driving end of the hydraulic cylinder, and a support assembly is provided on the support platform;

[0007] The cross is connected to an extrusion block via an electric push rod, and the extrusion block is provided with two trapezoidal openings with right-angled trapezoidal cross-sections. Two positioning assemblies are provided on the cross, and each positioning assembly includes a bending rod slidably mounted on the cross, a support plate is fixedly connected to the bending rod, a cooling box is fixedly connected to the support platform, and a discharge assembly is provided on the cooling box.

[0008] Preferably, the discharge assembly includes a discharge pipe fixedly mounted on the cooling box, and a manual valve is provided on the discharge pipe.

[0009] Preferably, one end of the discharge pipe is threadedly connected to a sealing sleeve, and a sealing ring and a filter are fixedly connected to the sealing sleeve.

[0010] Preferably, each of the bending rods is sleeved with a spring, one end of the spring is fixedly connected to the bending rod, and the other end of the spring is fixedly connected to the cross.

[0011] Preferably, a limiting groove is provided on the bracket, and the slider is slidably connected to the limiting groove.

[0012] Preferably, the support assembly includes two support blocks fixedly mounted on the support platform, and the cross section of each support block is T-shaped.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The electric push rod works until the surface of the bending rod fits the inner surface of the flange blank, and then the hydraulic cylinder drives the cross to move upward, and each support plate will move upward together with the lower surface of the flange blank. When the flange blank is directly above the cooling box, the flange blank is moved down to the inside of the cooling box. There is sufficient oil quenching liquid inside the cooling box. The oil quenching liquid ensures sufficient cooling and avoids cracking of the flange blank. The flange blank can be immersed in the oil quenching liquid for rapid cooling. After the cooling is completed, the hydraulic cylinder can move the cross upward, and the flange blank can be taken out of the cooling box. This not only improves the cooling speed of the flange blank, but also facilitates the pick-and-place operation of flange blanks with different apertures, which is beneficial to the processing of the flange.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0023] Reference Figure 1-Figure 5 A high-hardness flange heat treatment processing equipment includes a support platform 1 and a bracket 5 fixedly mounted on the support platform 1, a reciprocating screw 12 is rotatably mounted on the bracket 5, a slider 13 is threadedly connected to the reciprocating screw 12, a hydraulic cylinder 11 is fixedly mounted on the bottom of the slider 13, and a driving end of the hydraulic cylinder 11 is fixedly connected to a cross 10, a support assembly is provided on the support platform 1, an extrusion block 9 is connected to the cross 10 through an electric push rod 16, and the extrusion block 9 is provided with two trapezoidal openings 17 with a right-angled trapezoidal cross-section, and two positioning assemblies are provided on the cross 10, each positioning assembly includes a bending rod 6 slidably mounted on the cross 10, and the bending rod 6 is fixedly connected to a support plate 7, a cooling box 2 is fixedly connected to the support platform 1, and a discharge assembly is provided on the cooling box 2.

[0024] The discharge assembly includes a discharge pipe 3 fixedly mounted on the cooling box 2, a manual valve (not shown) is provided on the discharge pipe 3, one end of the discharge pipe 3 is threadedly connected to a sealing sleeve 4, a sealing ring (not shown) and a filter 14 are fixedly connected to the sealing sleeve 4, the manual valve is threadedly connected to the discharge pipe 3 and the connection is well sealed, when the manual valve is unscrewed, the oil quenching liquid inside the cooling box 2 can be discharged through the discharge pipe 3 and the sealing sleeve 4, the filter 14 can filter the debris contained in the oil quenching liquid, when the sealing sleeve 4 is connected to the discharge pipe 3, the rubber sealing ring is clamped between the sealing sleeve 4 and the discharge pipe 3 to ensure the sealing when the sealing sleeve 4 is connected to the discharge pipe 3, and the sealing sleeve 4 can be detached from the discharge pipe 3 by rotating the sealing sleeve 4 to make it easier to clean the filter 14.

[0025] Each bending rod 6 is sleeved with a spring 15, one end of the spring 15 is fixedly connected to the bending rod 6, and the other end of the spring 15 is fixedly connected to the cross 10. When the electric push rod 16 works and drives the extrusion block 9 and the cross 10 to slide relative to each other, the inclined inner walls of each trapezoidal opening 17 will move simultaneously along the end face of the corresponding bending rod 6, thereby causing the two bending rods 6 to slide relative to the cross 10 at the same time, the spring 15 is deformed, and a limiting groove is provided on the bracket 5. The slider 13 is slidably connected to the limiting groove. The limiting groove can limit the moving trajectory of the slider 13 to prevent the slider 13 from swinging.

[0026] The support assembly includes two support blocks 8 fixedly mounted on the support platform 1. The cross-section of each support block 8 is T-shaped. The heat-treated flange blank is placed on the two support blocks 8, and the flange blank is basically centered above the two support blocks 8, so that during the subsequent movement of the support plate 7, not only can the flange blank be automatically picked up and placed, but collision between the support plate 7 and the support block 8 can also be effectively avoided.

[0027] In the present invention, when in use, the flange blank after heat treatment is placed on the two support blocks 8, and the flange blank is basically centered above the two support blocks 8, and then the servo motor drives the reciprocating screw 12 to rotate until the cross 10 is directly above the two support blocks 8, and the hydraulic cylinder 11 drives the cross 10 to move downward. At this time, the distance between the two support plates 7 reaches the minimum, and the two support plates 7 will penetrate the middle hole of the flange blank during the downward movement. Since the electric push rod 16 is fixedly connected to the cross 10, and the driving end of the electric push rod 16 is fixedly connected to the extrusion block 9, the electric push rod 16 then works, driving the extrusion block 9 and the cross 10 to slide relative to each other, and the inclined inner walls of each trapezoidal opening 17 move simultaneously against the end faces of the corresponding bending rods 6, thereby causing the two bending rods 6 to slide relative to the cross 10 at the same time, and the distance between the two bending rods 6 increases until the surface of the bending rod 6 fits the inner surface of the flange blank.

[0028] Afterwards, the hydraulic cylinder 11 drives the cross 10 to move upward. During the upward movement of each support plate 7, it will move upward together with the lower surface of the flange blank. Then, the servo motor drives the reciprocating screw 12 to rotate. When the flange blank is directly above the cooling box 2, the hydraulic cylinder 11 drives the cross 10 to move downward, so that the flange blank on the support plate 7 moves down to the inside of the cooling box 2. There is a sufficient amount of oil quenching liquid inside the cooling box 2. The oil quenching liquid ensures sufficient cooling and avoids cracking of the flange blank. The flange blank can be immersed in the oil quenching liquid for rapid cooling. After the cooling is completed, the hydraulic cylinder 11 can move the cross 10 upward, and the flange blank can be taken out of the cooling box 2. This not only improves the cooling speed of the flange blank, but also facilitates the pick-and-place operations on flange blanks with different apertures, which is beneficial to the processing of the flange.

[0029] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
