Referring to fig. 1, the heat dissipation module 1 generally includes a heat dissipation base 101 made of aluminum and a fluid pipe 102 made of copper. Since the surface of the device to be cooled is generally a planar structure, in order to make the heat dissipation module 1 fit with the device to be cooled as much as possible, in the production process, as shown in fig. 2, after the fluid pipeline 102 is placed on the heat dissipation base 101, the middle pipe segment 1021 of the fluid pipeline 102 needs to be pressed down to be flush with the heat dissipation base 101.

The existing pressing equipment comprises a jig assembly used for containing the heat dissipation module 1, a pressing plate located right above the middle pipe section 1021 and a pressing pipe cylinder driving the pressing plate to move up and down. Specifically, after the heat dissipation module 1 shown in fig. 1 is placed on the jig assembly, the pressing cylinder drives the pressing plate to move downward, so as to flatten the middle pipe section 1021 of the fluid pipeline 102.

In actual work, after the type of the pressure pipe cylinder is determined, the single expansion stroke of the pressure pipe cylinder is fixed, so that the middle pipe section 1021 of the fluid pipeline 102 can be flattened only once during pressure pipe operation, and the pressure pipe cannot be pressed down in multiple times. However, the intermediate tube section 1021 is flattened once, so that the intermediate tube section 1021 is deformed too severely, cracks are likely to occur in the intermediate tube section 1021, and the flatness of the intermediate tube section 1021 is poor.

Therefore, the existing pressing equipment needs to be improved to solve the problems that the middle pipe section of the fluid pipeline is easy to crack and poor in flatness due to the fact that the pressing operation cannot be performed on the fluid pipeline in a grading mode.

Referring to fig. 3 and 4, in the present embodiment, the stepped rolling device includes a bottom plate 2, a driving module bracket 3, a jig assembly 4, a plurality of roller brackets 5, a plurality of downward pressing linear driving modules 6, a plurality of pre-pressing rollers 7, and a pressing roller 8.

The jig component 4 and the driving module support 3 are both fastened and installed on the bottom plate 2, the driving module support 3 is of an inverted U-shaped structure, and the jig component 4 is located below the driving module support 3.

The roller bracket 5 is also in an inverted U-shaped structure and is positioned above the jig component 4. The flattening rotating rollers 8 and each prepressing rotating roller 7 are rotatably arranged in one rotating roller bracket 5, so that the flattening rotating rollers 8 and the prepressing rotating rollers 7 can rotate independently without mutual interference. Further, each of the downward linear driving modules 6 is installed on the driving module support 3, and the driving end of each of the downward linear driving modules 6 is connected to one of the roller supports 5, so as to drive the corresponding roller support 5 to approach or leave the jig assembly 4. Therefore, the flattening rotating rollers 8 and the pre-pressing rotating rollers 7 can move up and down independently along with the corresponding rotating roller supports 5 without mutual interference.

In this embodiment, in order to avoid the horizontal offset when the flattening rollers 8 and the pre-pressing rollers 7 move up and down, each of the roller brackets 5 is connected with a plurality of guide posts 9, and each of the guide posts 9 is connected with the driving module bracket 3 in a vertically sliding manner, so that the roller brackets 5 can be well guided up and down.

The jig assembly 4 is used for sequentially conveying the workpiece to be pressed to the abdicating groove 701 and the flattening roller 8 for fitting. Specifically, the jig assembly 4 includes a jig body 401, a conveying platform 402, and a feeding linear driving module 403. The jig body 401 is used for placing the workpiece to be pressed; the jig body 401 is mounted on the conveying platform 402; the driving end of the feeding linear driving module 403 is connected to the conveying platform 402.

The following description takes the number of the pre-pressing rollers 7 as an example, and at the beginning, all the downward-pressing linear driving modules 6 are in a retraction state, that is, the pressing rollers 8 and the pre-pressing rollers 7 are in a higher position, and the working process of the stepped rolling equipment provided by this embodiment is as follows:

s10: the feeding linear driving module 403 conveys the conveying platform 402 and the jig body 401 to one side close to the feeding station, so as to place the heat dissipation module into the jig body 401;

s20: after the heat dissipation module is put into the jig, the jig body 401 carrying the heat dissipation module is conveyed to the lower part of the pre-pressing roller 7 by the linear material driving module:

the specific process of step S20 is as follows:

s201: at the beginning, the end part of the fluid pipeline is positioned right below the pre-pressing roller 7, and the position does not need to be flattened, so the pre-pressing roller 7 keeps a higher position and does not move downwards;

s202: when the middle pipe section of the fluid pipeline moves to the position right below the pre-pressing roller 7, the pressing linear driving mechanism connected with the pre-pressing roller 7 immediately drives the pre-pressing roller 7 to move downwards, and the middle pipe section is located in the abdicating groove 701, generally, the groove depth of the abdicating groove 701 is slightly smaller than the radius of the fluid pipeline, so that the middle pipe section can partially deform downwards under the extrusion action of the groove wall of the abdicating groove 701, namely, the protrusion height of the middle pipe section relative to the heat dissipation base can be reduced;

s203: the feeding linear driving module 403 continues feeding operation, and the jig body 401 drives the whole middle pipe section to pass below the abdicating groove 701, specifically, the pre-pressing roller 7 rolls on the whole middle pipe section, so that the protrusion height of the whole middle pipe section relative to the heat dissipation base is reduced, and the first pressing is performed;

s30: after the middle pipe section is pressed down for the first time, the middle pipe section is conveyed to the position right below the flattening rotary roller 8, the flattening rotary roller 8 is driven to move downwards by a linear driving module connected with the flattening rotary roller 8 to be attached to the upper surface of the heat dissipation base, and then the middle pipe section is pressed down for the second time;

the specific process of step S30 is as follows:

s301: when the middle pipe section of the fluid pipeline moves to the position right below the flattening rotary roller 8, the flattening rotary roller 8 is driven to move downwards by the pressing linear driving mechanism connected with the flattening rotary roller 8 and is attached to the upper surface of the heat dissipation base; because the circumferential surface of the flattening roller 8 is not provided with a groove, the middle pipe section can be directly pressed down to be flush with the upper surface of the heat dissipation base;

s302: the feeding linear driving module 403 continues feeding operation, and the jig body 401 drives the whole middle pipe section to pass below the flattening roller 8, specifically, the flattening roller 8 rolls on the whole middle pipe section, so that the whole middle pipe section is flush with the upper surface of the heat dissipation base, and the second pressing is performed;

it should be noted that, no matter whether the middle pipe section is pressed down for the second time or not, as long as the whole middle pipe section passes through the pre-pressing roller 7, the pre-pressing roller 7 is immediately lifted, so as to prevent the pre-pressing roller 7 from affecting the end position of one end of the fluid pipeline;

in a similar way, no matter whether the middle pipe section finishes the first pressing, as long as the middle pipe section does not enter the pressing area of the pressing roller 8, the pressing roller 8 does not move downwards, so that the pressing roller 8 does not influence the end position of the other end of the fluid pipeline.

The cascaded rolling equipment that this embodiment provided uses the pre-compaction that has the recess 701 of stepping down earlier and changes roller 7 to preliminary pushing down to the middle pipeline section of fluid pipeline, then uses to flatten and changes roller 8 and put in place the middle pipeline section suppression, pushes down the operation to the fluid pipeline through the mode that pushes down in gradation, and then solves the problem that the crackle appears easily in the middle pipeline section of fluid pipeline, moreover, the gradation pushes down the roughness that also is favorable to improving middle pipeline section.

It should be noted that, each linear drive module all can be for telescopic cylinder, rodless cylinder, electric cylinder or motor lead screw sliding block set etc. the utility model discloses do not do the restriction to this. Preferably, in this embodiment, the downward linear driving module 6 is a telescopic cylinder, and the feeding linear driving module 403 is a motor screw rod slider assembly.

Of course, in some other embodiments, when the diameter of the fluid pipeline is larger, there may be a situation that the protrusion height of the middle pipe section is too high compared to the upper surface of the heat dissipation base at the beginning, and at this time, it may be insufficient to perform the flattening operation of the middle pipe section twice, therefore, referring to fig. 5 and 6, one or more pre-pressing rollers 7 may be additionally provided according to the requirement of the machining precision, and the groove depth dimension of the abdicating groove 701 of each pre-pressing roller 7 gradually decreases toward the direction approaching the flattening roller. Therefore, the middle pipe section can deform a little downwards when passing through the pre-pressing roller 7, and can be pressed to be flush with the upper surface of the heat dissipation base when passing through the last flattening roller. Therefore, the problem that the initial projection height of the middle pipe section is too high can be effectively solved by pressing for multiple times.

Further, the groove depth of the abdicating groove 701 of each pre-pressing roller 7 decreases in an equal proportion towards the direction close to the flattening rollers 8, so that the whole pressing process is more uniform and stable.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.

The above list of detailed descriptions is only for the specific description of the feasible embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the technical spirit of the present invention should be included within the scope of the present invention.
