Description

Cooling device for quenching processing

Technical Field

The utility model belongs to the technical field of quenching processing equipment, and particularly relates to a cooling device for quenching processing.

Background

The cooling device can be used when the metal workpiece is quenched, and the document with the publication number of CN209081935U discloses an air-cooled quenching device which can adjust the wind power and adapt to the specification and the size of the workpiece, has certain beneficial effects, but has some defects to be solved.

Firstly, the above patent document can only cool one surface (i.e. the upper surface) of the workpiece by air cooling, that is to say, the air is only blown from top to bottom, and other surfaces of the workpiece have no direct blowing, so that different surface cooling amplitudes of the workpiece are different, and when the workpiece is cooled rapidly, the workpiece at high temperature can generate obvious buckling deformation due to the different cooling amplitudes, so that the quality of the product is greatly affected. Although the occurrence of the above-described defects can be reduced by extending the cooling time, the quenching effect is lost in this way, and the defects are more remarkable.

Secondly, whether air cooling, water cooling or oil cooling is adopted, the cooling device is used for realizing uniform and rapid cooling of the workpiece as much as possible, and thus, all surfaces of the workpiece are required to be contacted with a cooling medium uniformly and comprehensively. If the air cooling mode is used for cooling, the wind power near the center of the equipment is required to diffuse outwards, the more resistance the wind power receives, the flow is blocked, and the higher temperature heat exchange is restricted. The wind power closer to the edge of the equipment is easier to be diffused and discharged, and the smooth heat exchange efficiency with small resistance flow is also higher. The temperature reduction amplitude of the surface of the workpiece is different, and finally, the deformation of the product can be caused.

At present, cooling equipment for thin workpieces is also available, but only the workpieces can be clamped one by one and then immersed in oil for cooling, so that the operation is very complicated, the efficiency is low, and the equipment is not suitable for the requirements of automatic processing and production.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1 to 7, the embodiment of the present utility model provides a cooling apparatus for quenching process, comprising a plurality of lower transfer rollers 100 for transferring a workpiece 3 (e.g., a thin workpiece such as a knife, a shovel, etc.), and the workpiece 3 is transferred by being placed on the lower transfer rollers 100 (refer to fig. 6); a plurality of upper conveying rollers 200 corresponding to the upper conveying rollers are arranged above the lower conveying rollers 100, the upper conveying rollers 200 and the lower conveying rollers 100 respectively perform synchronous reverse transmission under the transmission of a driving component (a driving motor), and workpieces 3 are conveyed between the upper conveying rollers 200 and the lower conveying rollers 100. In this process, the work 3 can be held by the upper conveying roller 200 and the lower conveying roller 100 together, so that a better up-down holding effect can be achieved, and the flatness of the work can be ensured, which is preferable. However, the clamping force needs to be accurately controlled, otherwise, the workpiece 3 is thinned. It is also possible to leave a certain gap between the upper conveying roller 200 and the workpiece 3, which are not in contact with each other, so that the workpiece 3 is not thinned, but the gap is not easily too large, otherwise, the workpiece 3 is slightly warped and deformed (refer to fig. 3). Of course, if the thickness of the workpiece is large, no warping will occur, and the manner of pressing and conveying by an upper conveying roller is not needed.

The upper and lower conveying rollers 200 and 100 are respectively fixed to an upper case 201 and a lower case 101 having a medium conveying member 4, wherein the medium conveying member 4 is used for conveying a cooling medium (such as a fluid of water, wind or oil). The opposite surfaces of the upper case 201 and the lower case 101 are respectively provided with a plurality of tubes 8 penetrating the outside, which are used for accurately and directionally conveying the medium. In particular use, the end b of the tube 8 is placed in said gap 9 (see fig. 3). The end b of the pipe 8 faces the gap 9 between the upper conveying rollers 200 and the lower conveying rollers 100, and the medium is conveyed into the upper box 201 and the lower box 101 through the medium conveying component 4, and is conveyed toward the workpiece 3 through the pipe 8 for cooling. The medium is finally discharged from both axial ends of the upper and lower conveying rollers 200 and 100.

Through the structure, the workpiece 3 can be directly contacted with the medium in the upper and lower directions, and the medium is indirectly contacted in the peripheral direction, so that the cooling is more comprehensive. In the conveying process, the workpiece 3 is preferably conveyed by sandwiching the workpiece 3 between the upper conveying roller 200 and the lower conveying roller 100, so as to prevent buckling deformation of the workpiece 3.

On the basis of the above technical solution, in order to cool the workpiece 3 more comprehensively, the pipe elements 8 in each adjacent gap 9 are corresponding to each other in a staggered manner (refer to fig. 6-7). That is, the pipe fittings 8 are arranged side by side in the gaps 9, and each pipe fitting 8 is staggered and corresponds to each other, so that the upper surface and the lower surface of the workpiece 3 can be comprehensively contacted with the medium, and no dead angle is omitted.

The height of the end b of the pipe 8 located in the upper case 201 is higher than the height of the bottom end of the upper transfer roller 200, and the height of the end b of the pipe 8 located in the lower case 101 is lower than the height of the top end of the lower transfer roller 100, so that the end of the pipe 8 does not obstruct the transfer of the workpiece 3. When the upper transfer roller 200 is not in contact with the workpiece 3, the end b of the pipe member 8 may continue to extend downward as long as it does not contact the blocking workpiece 3.

As a further technical solution, the distance a between the end b of the pipe 8 and the surface of the workpiece 3 is 0.5-1.5cm (refer to fig. 3). The above dimensions are adopted in order to allow the medium to be cooled in contact with the workpiece 3 accurately and comprehensively. If the distance is too large, the medium will be scattered in turbulence and cannot flow in a cluster state, and the flow, speed and direction of the medium will be greatly changed, thus being easy to cause uneven cooling. After the technical scheme is adopted, no matter a certain part of a single workpiece or a single workpiece at a certain position is subjected to medium with uniform flow, speed and direction to cool, so that the workpiece 3 is uniformly and comprehensively cooled, and the warp deformation is prevented.

As a further solution, the section of the tube 8 located in the gap 9 is in a flat configuration (see fig. 4-5).

The beneficial effect of above-mentioned structure is: the pipe fitting 8 can be placed in the gap 9 with limited space, and the smaller the space of the gap 9 is, the smaller the size of the workpiece 3 can be applied, and the application range is wider.

In order to adjust the height to accommodate the workpieces 3 with different thicknesses, the upper case 201 is moved toward the lower case 101 or away from the lower case 101 by a lifting mechanism; the lifting mechanism comprises a screw rod 700, the upper box 201 is movably sleeved with the screw rod 700 through a supporting lug 701, a screw seat 702 which is connected with the screw rod 700 in a screw mode and is positioned below the supporting lug 701 is arranged on the screw rod 700, and the screw seat 702 is in contact with the supporting lug 701 through ascending or descending of the screw rod 700 so as to control the lifting of the upper box 201.

When the screw base 702 is screwed up on the screw 700, the supporting lug 701 is propped up to rise, and the supporting lug 701 is only sleeved on the screw 700, and the supporting lug and the screw base are not screwed up, so that the upper box 201 can be driven to rise. Otherwise, the level is lowered (refer to fig. 1-2).

In the actual use process, when the thickness of the workpiece is slightly thickened, the height of the upper box 201 does not need to be adjusted first. Because the upper box 201 is naturally jacked up just when the workpiece 3 is clamped and conveyed, the supporting lug 701 and the wire seat 702 are separated from each other, and the worker can lift the wire seat 702 in a screwing way more labor-saving manner. In order to avoid excessively thinning the workpiece (or adjusting the gravity of the upper box 201), a worker can additionally screw one or two more rings of wires after screwing the wire holder 702, so that the height of the upper box 201 is slightly increased again, that is, the weight of the upper box 201 is offset by the wire holder 702, so that the pressing force of the workpiece 3 can be greatly reduced, thinning is prevented, and meanwhile, the clamping and conveying effects can be realized.

Referring to fig. 1-2, in order to achieve different air volumes and different directions for conveying the media, a diversion chamber 500 is respectively provided between the upper case 201 and the media conveying component 4 and between the lower case 101 and the media conveying component 4, and at least one baffle 6 for separating the media is respectively provided in the diversion chamber 500, the upper case 201 and the lower case 101 for separating the internal space into different spaces. The valve 501 for adjusting the flow is arranged between the upper box 201 and the flow distribution chamber 500 and between the lower box 101 and the flow distribution chamber 500, and the flow of the medium in different spaces is adjusted through the valve 501, so that the operation is more flexible and various.

As a further technical solution, the medium conveying component 4 is a blower, a water pump or an oil pump. That is, the technical scheme can adopt a fluid cooling mode such as air cooling, water cooling or oil cooling to cool, and can be selected one by one according to different product materials or requirements. The workpiece is made of various materials, if the workpiece is made of medium carbon steel, the workpiece is mainly water-cooled, the workpiece is made of high carbon steel or alloy, the workpiece is made of oil-cooled, and the workpiece is made of stainless steel, the workpiece is made of air-cooled.

The utility model can realize uniform and rapid cooling of the workpiece, and meanwhile, the workpiece cannot warp and deform, so that the flatness quality of the product is ensured. The cooling medium can also be changed according to the different materials of the workpiece, such as water cooling, air cooling or oil cooling.

Description of principle:

the workpiece 3 is pinch-conveyed between the upper conveying roller 200 and the lower conveying roller 100, and in this way, warp deformation of the workpiece can be prevented. A gap 9 is left between each adjacent two of the upper conveying rollers 200 and each adjacent two of the lower conveying rollers 100 for the medium to blow toward the work 3. The end of the pipe fitting 8 extends into the gap 9 and approaches the upper and lower surfaces of the workpiece 3, the medium can contact the upper and lower surfaces of the workpiece 3 at a short distance, the medium flows through a short distance, the flow, speed and direction are more stable, and otherwise, the medium is more disordered, so that the uniform cooling of the workpiece is ensured. Eventually, the medium is discharged from both axial ends of the conveying roller. When the medium is wind, water or oil, the same operation flow is adopted.

Although the utility model has been described hereinabove with reference to embodiments, various modifications thereof may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model. In particular, the features of the disclosed embodiments may be combined with each other in any manner so long as there is no structural conflict, and the exhaustive description of these combinations is not given in this specification merely for the sake of brevity and resource saving. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
