Description

Roller deep cooling box

Technical Field

The utility model relates to a roll production field, in particular to roll cryogenic box.

Background

The cryogenic treatment is a supplementary process of ordinary heat treatment, which is a process of treating materials in a certain low-temperature environment according to a certain process. The research and application of the surface cryogenic treatment can effectively improve the mechanical properties of the material, such as wear resistance, dimensional stability, strength, toughness and the like, thereby improving the quality of the product, prolonging the service life and finally reducing the production cost. The technology is industrialized as early as sixty-seven years when developed countries such as the United states and the like are launched into the countries, and in recent years, some large and small enterprises in China are provided with a process of adding cryogenic treatment on production lines.

And the ultra-low temperature liquid nitrogen (-196 ℃) is used as a cooling medium, so that the cooling process of the quenched metal material can be continued to reach a certain temperature far lower than the room temperature, and the residual austenite existing after the conventional heat treatment is promoted to be further converted, thereby improving the performance of the metal material. Generally, at present, a fan or a blower is generally adopted in a cryogenic treatment device to blow liquid nitrogen into equipment, so that a workpiece is cooled. There are problems in that: (1) the problems of high failure rate and short service life of the fan or the blower under the low-temperature severe working condition exist; (2) the roller cannot be cooled uniformly.

SUMMERY OF THE UTILITY MODEL

To the defect that prior art exists above, the utility model discloses a main aim at overcomes prior art's weak point, discloses a roll cryogenic box, be in including box and setting rack in the box, the rack includes lower carriage, initiative cylinder, driven cylinder and actuator, the initiative cylinder with driven cylinder sets up the lower carriage is expert at, and the roll is placed on initiative cylinder and the driven cylinder, the actuator sets up outside the box, utilize the actuator drive the initiative cylinder rotates and makes the roll rotate, all be provided with row's of going up nozzle and lower nozzle down on two relative inner walls of box, it all is connected to on the liquid nitrogen supply jar through the pipe connection to go up nozzle and lower nozzle down.

Further, the device comprises an upper bracket, a driven roller arranged on the upper bracket and an adjusting device for adjusting the height of the upper bracket.

Further, adjusting device includes handle, guide, regulating plate, the regulating plate sets up on the guide, the regulating plate upper end sets up the screw rod, the handle sets up outside the box, and with screw rod threaded connection utilizes the handle drive the vertical removal of regulating plate.

Furthermore, the adjusting plate is provided with an adjusting hole for adjusting the position of the upper bracket.

Further, the actuator is a motor.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model discloses a roll deep-cooling box, as shown in fig. 1-4, including box 1 and the rack of setting in box 1, the rack includes lower carriage 2, initiative cylinder 3, driven cylinder 4 and actuator 5, and initiative cylinder 3 and driven cylinder 4 set up on lower carriage 2, and the roll is placed on initiative cylinder 3 and driven cylinder 4, and actuator 5 sets up outside box 1, and actuator 5 can be the motor, utilizes actuator 5 drive initiative cylinder 3 to rotate and makes the roll rotate, supports the roll through driven cylinder 4. An upper row of nozzles 6 and a lower row of nozzles 7 are arranged on two opposite inner walls of the box body 1, and the upper row of nozzles 6 and the lower row of nozzles 7 are connected to a liquid nitrogen supply tank through pipelines.

In one embodiment, the device further comprises an upper bracket 8, a driven roller 4 arranged on the upper bracket 8, and an adjusting device 9 for adjusting the height of the upper bracket 8. The moving range of the roller is limited by arranging the driven roller 4 above and the driven roller 4 and the driving roller 3 below. Specifically, adjusting device 9 includes handle 91, guide 92, regulating plate 93, and regulating plate 93 sets up on guide 92, and guide 92 includes parallel arrangement at two guide arms for support and guide regulating plate 93 vertical movement, and regulating plate 93 upper end sets up screw 94, and handle 91 sets up outside box 1, and with screw 94 threaded connection, through rotating handle, make screw 94 shift up, and then drive regulating plate 93 shifts up.
