Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deep processing device, in particular to a billet deep processing device and a using method thereof. BACKGROUND

[0002] As a supplementary process of ordinary heat treatment, deep processing is a process of placing the billet in a certain low temperature environment and processing according to a certain process. Research and application of surface deep processing can effectively improve the mechanical properties of the billet such as wear resistance, dimensional stability, strength and toughness, so as to improve the quality of the product, prolong the service life and ultimately reduce the production cost. The United States and other developed countries industrialized this technology as early as in the 1960s and 1970s. In recent years, some domestic enterprises have added the deep processing process to their production lines.

[0003] In the traditional deep processing box, in order to make the refrigerant medium uniformly distributed in the box, an internal fan is designed. The fan has a stirring effect on one hand and can blow the refrigerant medium to the cooled object on the other hand to improve the cooling effect. However, since the refrigerant medium is injected from one side of the deep processing box, when the fan blows the refrigerant medium to the cooled object, the temperature of the area close to the fan side of the cooled object is lower, which is particularly obvious in the early stage of temperature drop, and easily causes uneven cooling of the billet, thereby affecting the surface deep processing effect of the billet outside, and affecting the mechanical properties such as dimensional stability, strength and toughness of the billet.

[0042] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0043] Please refer to Figures 1-7 , the present application provides a kind of embryo material cryogenic treatment device, including cryogenic tank 100, carrying module 200, cooling pipeline 300 and temperature detection module 400.

[0044] The top of the cryogenic tank 100 is provided with a cover 500, and the inside of the cryogenic tank 100 is formed with a cooling carrying chamber 110 and an exhaust chamber 120 from top to bottom respectively; wherein the cooling carrying chamber 110 can form a sealed space with the cover 500, so that the shaft-shaped embryo material is subjected to cryogenic treatment in the space, and the exhaust chamber 120 can receive the gas in the cooling carrying chamber 110, so that the pressure in the cooling carrying chamber 110 is within a specified pressure range.

[0045] The carrying module 200 is used for carrying and fixing the shaft-shaped embryo material, and is arranged at the middle position of the bottom of the cooling carrying chamber 110;

[0046] The temperature detecting module 400 comprises a temperature sensor arranged in the cooling object chamber 110; the temperature sensor can monitor the temperature in the cooling object chamber 110 in real time, so that the cooling object chamber 110 can be kept at a suitable temperature.

[0047] The cooling pipeline 300 is arranged on one side above the object module 200; one end of the cooling pipeline 300 is communicated with the cooling object chamber 110, and the other end of the cooling pipeline 300 is communicated with a refrigerant supply source (not shown); the cooling pipeline 300 is provided with a liquid nitrogen disperser (not shown) and an axial flow fan 310 at one end of the cooling object chamber 110; the refrigerant supply source supplies liquid nitrogen into the cryogenic box 100 through the cooling pipeline 300; when the liquid nitrogen is discharged, the liquid nitrogen disperser can disperse the liquid nitrogen, and then the axial flow fan 310 can make the supplied liquid refrigerant into mist or low-temperature gas move towards the object module 200 to perform cryogenic treatment on the blank.

[0048] Specifically, the object module 200 comprises an object table 210 rotatably arranged at the middle position of the bottom of the cooling object chamber 110, and a support assembly 220; the support assembly 220 is used for bearing and fixing the shaft-shaped blank, and prevents the object table 210 from being displaced when rotating; the object table 210 can rotate and drive the support assembly 220 to rotate, so that the outer side of the shaft-shaped blank is uniformly contacted with the supplied liquid refrigerant into mist or low-temperature gas, thereby uniformly cooling the outer side of the shaft-shaped blank, so as to prevent the temperature of the local area from being lower, thereby preventing the soft belt and even the crack phenomenon from occurring.

[0049] More specifically, the inside of the object table 210 forms an air inlet chamber 211; the top surface of the object table 210 is uniformly provided with strip-shaped through grooves 212 communicated with the air inlet chamber 211 in a width manner; the middle position of the bottom surface of the object table 210 is provided with an air outlet pipe 213 communicated with the air inlet chamber 211, and the bottom end of the air outlet pipe 213 extends into the air outlet chamber 120; the inside of the air outlet chamber 120 is provided with a driving device 214 for driving the air outlet pipe 213 to rotate, for example, the driving device 214 can be a motor; the output end of the motor is drivingly connected with the air outlet pipe 213 through a chain mechanism; the air outlet pipe 213 is driven to rotate by the rotation of the output end of the motor, thereby driving the object table 210 to rotate; the support assembly 220 comprises a support strip 221 fittingly arranged in the strip-shaped through grooves 212; the bottom of the support strip 221 is provided with a blocking plate 222; the blocking plate 222 and the bottom of the air inlet chamber 211 are provided with a return spring 223 therebetween; the two sides of the support strip 221 in the thickness direction are provided with air inlet grooves 224, and the depth of the air inlet grooves 224 along the height direction of the support strip 221 is continuously decreased.

[0050] When the shaft-shaped blank is placed on the support table 210, the shaft-shaped blank should be first kept parallel to the support bars 221, and then placed on the support assembly 220. When the shaft-shaped blank is placed on the support assembly 220, the support bars 221 in contact with the shaft-shaped blank are pressed to deform the return springs 223, and the pressed support bars 221 move into the air inlet chamber 211. When the shaft-shaped blank contacts the top surface of the support bars, the support bars 221 in contact with the outer surface of the shaft-shaped blank form a groove similar to the shape of the shaft-shaped blank. The groove can limit the displacement of the shaft-shaped blank during the rotation of the support table 210.

[0051] When the pressed support bars 221 are displaced, the air inlet grooves 224 provided in the thickness direction of the support bars 221 can communicate the cooling object chamber 110 with the air exhaust chamber 120. Thus, when the air pressure in the cooling object chamber 110 increases, the gas in the cooling object chamber 110 moves towards the air inlet grooves 224. The air inlet grooves 224 are located on the pressed support bars 221, i.e. a low-temperature gas flow path is generated in the cooling object chamber 110 and moves towards the shaft-shaped blank. In addition, the shaft-shaped blank is continuously rotating. The low-temperature gas flow path can quickly and uniformly contact the cooling shaft-shaped blank to improve the effect of the cryogenic treatment.

[0052] Further, the top of the support bar 221 has a tapered portion 225, and the tapered portion 225 is uniformly provided with air passage grooves 226 along the length direction. The tapered portion 225 can reduce the contact between the support bar 221 and the shaft-shaped blank, and the air passage grooves 226 can make the low-temperature gas flow path move through the air passage grooves 226 towards the bottom of the shaft-shaped blank, so that the lower half of the shaft-shaped blank forms a gas flow adhering to the shaft-shaped blank. The displacement amount of the support bar 221 at the bottom of the shaft-shaped blank is the largest, and the depth of the air inlet grooves 224 along the height direction of the support bar 221 decreases continuously. Thus, the cross section of the air inlet grooves 224 of the support bar 221 at the bottom of the shaft-shaped blank is the largest. When the air pressure in the cooling object chamber 110 increases, the gas moves to the air inlet grooves 224 with the largest cross section to release pressure.

[0053] Further, the air inlet grooves 224 are provided in the middle of the length direction of the support bar 221, so that the adjacent two support bars 221 form a gas flow path moving from the two ends of the shaft-shaped blank towards the center.

[0054] Further, the air exhaust chamber 120 is further provided with an air outlet pipe 121 communicating with the outside, and the air outlet pipe 121 is provided with a spring safety valve 122.

[0055] Further, the liquid nitrogen disperser is made of a stainless steel ring pipe with small holes on the top.

[0056] Further, the cooling pipeline 300 is provided with an electromagnetic valve 320, and the refrigerant supply source is used to supply liquid nitrogen.

[0057] The application further provides a method for using the embryo material cryogenic treatment device, comprising the following steps:

[0058] S1: making the shaft-shaped embryo material parallel to the length direction of the support strip 221, placing the shaft-shaped embryo material on the support strip 221 of the object table 210, and closing the cryogenic box 100;

[0059] S2: starting the driving device 214, and driving the object table 210 to rotate the shaft-shaped embryo material by opening the electromagnetic valve 320 and driving the driving device 214 to rotate through the exhaust pipe 213; the refrigerant supply source guides the liquid nitrogen into the cooling object chamber 110 through the cooling pipeline 300, and reduces the temperature in the cooling object chamber 110 to-160±1℃ within 1h;

[0060] S3: after the temperature in the cooling object chamber 110 is reduced to-160±1℃, keeping warm for 2h; during the keeping warm process, the cryogenic box 100 ensures that the temperature in the box is unchanged by spraying liquid nitrogen;

[0061] S4: after the keeping warm process is completed, opening the cryogenic box 100, placing the shaft-shaped embryo material in a room temperature environment, and naturally recovering to room temperature to complete the embryo material cryogenic treatment.

[0062] The above is only the preferred embodiment of the application, but the protection scope of the application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered in the protection scope of the application.
