Description

Technical Field

[0001] The present application belongs to the technical field of metal heat treatment, and in particular relates to a multi-stage quenching and cooling insulation device. Background Art

[0002] The quenching process is a metal heat treatment process that heats the metal workpiece to a certain appropriate temperature and maintains it for a period of time, and then immerses it in a quenching medium for rapid cooling. The steel that has undergone the quenching process has higher hardness and wear resistance. In the cooling process of shaft metal workpieces, if the cooling speed of the shaft metal workpieces is inconsistent, the properties of the obtained metal will be inconsistent, and the cooling speed cannot be too fast, otherwise it will cause uneven stress inside the workpiece, causing the workpiece to deform. In actual production, certain processing sections of shaft metal workpieces are usually temperature-controlled separately according to usage requirements to slow down their cooling speed, thereby achieving different performance. Due to the long length and heavy weight of shaft workpieces, when insulating certain processing sections, it is necessary to use an insulation device to wrap the processing section, which is very cumbersome. If the length of the processing section to be insulated is too long, it is necessary to replace a larger insulation device for insulation, which further increases the cumbersomeness and is not conducive to improving production efficiency.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0017] The present application embodiment provides a multi-stage quenching cooling insulation device, such as Figure 1 Figure 2 As shown, it includes a slide rail 1, and the inner walls on both sides of the slide rail 1 are provided with matching grooves 11 along the length direction; the mounting plate 2 includes a bearing plate 28 located above the slide rail 1 and arranged along the width direction of the slide rail 1, and a matching plate 29 is arranged at the lower end of the bearing plate 28. Matching blocks 291 arranged along the length direction of the slide rail 1 are provided on both sides of the matching plate 29, and the matching blocks 291 are slidably matched in the matching grooves 11. The number of mounting plates 2 is three, and the length of the slide rail 1 can be adjusted according to the different lengths of the processed shaft workpieces, thereby increasing or reducing the number of mounting plates 2, and two guide rails 21 arranged along the width direction of the slide rail 1 are provided on the surface of the bearing plate 22; an insulation cabin 3 is installed on the bearing plate 22, which includes two arc frames 31 that are slidably matched on the guide rails 21 and are arranged opposite to each other, for fitting the surface of the metal workpiece, and the arc frames 31 are filled with high-temperature resistant insulation materials, and the insulation cabins 3 are detachably connected; support seats 4 are vertically connected to both ends of the slide rail 1, and a U-shaped groove 41 is provided at the upper end of the support seat 4.

[0018] When in use, first move the two arc frames 31 along the width direction of the slide rail 1 to separate the two arc frames 31 to leave space for loading shaft workpieces; use a hanger to hang the shaft workpiece above the slide rail 1, and make the shaft workpiece face the length direction of the slide rail 1, and then vertically downward, put the two ends of the shaft workpiece into the U-shaped groove 41 of the support seat 4. At this time, the processing section of the shaft workpiece is set above the slide rail 1 and is located between the two arc frames 31; according to the position and length of the processing section that needs insulation treatment, select the number of insulation chambers 3 and adjust the position of the insulation chamber 3. If there is a processing section on the shaft workpiece that needs insulation treatment, select the insulation chamber closest to the processing section and move the insulation chamber 3 along the shaft. The workpiece is moved in the length direction to the processing section that needs insulation treatment; if there is a long processing section that needs insulation treatment on the shaft workpiece, two or three insulation chambers 3 are connected to form a large integrated insulation chamber 3, and then it is moved to the processing section that needs insulation treatment; the arc frame 31 is aligned with the processing section that needs insulation treatment, and the two arc frames 31 are close to each other along the width direction of the slide rail 1 until the upper and lower ends of the two arc frames 31 are respectively abutted against each other, so that the high-temperature resistant insulation material in the arc frame 31 completely wraps the processing section that needs insulation treatment to reduce the cooling rate; after the insulation treatment is completed, it is only necessary to separate the two arc frames 31 and lift the shaft workpiece out. The device simplifies the operation mode of insulation treatment of the processing section of the shaft workpiece through the moving setting of the mounting plate 2 and the relative moving setting of the two arc frames 31, and through the multi-stage insulation chamber design, saves manpower and material resources, improves the applicability of the device, and thus improves production efficiency.

[0019] Specifically, Figures 1 to 3As shown, a pair of mounting blocks 22 arranged along the length direction of the slide rail 1 are provided at one end of the bearing plate 28, and a mounting groove 23 is opened at the upper end of the mounting block 22, wherein a matching shaft 24 is provided in the mounting groove 23 of one mounting block 22 along the length direction of the guide rail 21, and a rotating shaft 25 is provided in the mounting groove 23 of the other mounting block 22 along the length direction of the guide rail 21, and a rotating plate 26 is rotatably provided on the rotating shaft 25, one end of the rotating plate 26 is located on the outer side of the mounting plate 2, and a barb is formed downwardly toward the bearing plate 28, the other end of the rotating plate 26 is located on the inner side of the mounting plate 2, and is connected to the mounting plate 2 by a locking spring 27, when the locking spring 27 is in a natural state, one end of the rotating plate 26 is coplanar with the matching shaft 24 along the length direction of the slide rail 1. When in use, the two bearing plates 28 are pushed closer to each other along the length direction of the slide rail 1. When the two bearing plates 28 are close to a predetermined distance, the barb at one end of the rotating plate 26 on one of the bearing plates 28 abuts against the matching shaft 24 on the other bearing plate 28, and the two bearing plates 28 continue to be brought closer to each other. At this time, the outer end of the barb abuts against the matching shaft 24 to move, prompting the other end of the rotating plate 26 to press down the locking spring 27. When the two bearing plates 28 abut against each other, that is, the two arc frames 31 above one bearing plate 28 abut against the two arc frames 31 on the other bearing plate 28 in the length direction of the slide rail 1, the inner end of the barb is buckled on the matching shaft 24 under the action of the locking spring 27, thereby realizing the connection between the insulation cabins 3. It is only necessary to press down the other end of the rotating plate 26 to rotate the rotating plate 26 to separate the barb from the matching shaft 24, thereby realizing the separation between the insulation cabins 3. Through the structural design of the rotating plate 26 and the arrangement of the matching shaft 24, the connection and separation between the heat preservation chambers 3 are realized in a simple and quick manner, which simplifies the use of the device and improves the processing efficiency.

[0020] Specifically, Figure 3 As shown, support plates 311 are provided on the top of the two arc-shaped frames 31 in parallel along the length direction of the slide rail 1, a locking pin 312 is vertically penetrated on the surface of one of the support plates 311, a locking block 313 is provided on one end of the locking pin 312 facing the other support plate 311, a knob 314 is vertically connected to the other end of the locking pin 312, and a locking hole 315 is opened on the surface of the other support plate 311 for only the locking pin 312 and the locking block 313 to pass through. When in use, the two arc frames 31 are close to each other, so that the locking pin 312 and the locking block 313 set on one plate 311 are inserted into the locking hole 315 opened on the other plate 311. When the two arc frames 31 are abutted, the locking block 313 is located on the outside of the other plate 311, and then the knob 314 is turned to make the locking pin 312 rotate around its own axis, and the locking block 313 is located outside the outline of the locking hole 315, so that the contact between the locking hole 315 and the other plate 311 is used to connect the two arc frames 31, which effectively avoids the problem of poor insulation effect caused by the displacement of the two arc frames 31 apart from each other during the insulation process, thereby ensuring the insulation effect of the device.

[0021] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
