Description

Technical Field

[0001] This application relates to the field of heat dissipation structure technology, and in particular to a rapid heat conduction structure for a servo press guide rail based on heat pipe technology. Background Technology

[0002] When a servo press is working under high load, its guide rail structure will generate heat rapidly due to high-speed friction with the sliding structure. Natural cooling methods cannot meet the heat dissipation requirements. If it continues to work for a long time, the temperature of the guide rail will continue to rise, causing irreversible damage to the guide rail components. The traditional solution is to continuously spray low-temperature lubricant on the outer surface of the guide rail, which is not only inefficient but also easy to contaminate the worktable. Utility Model Content

[0003] The purpose of this application is to provide a clean, efficient, and high-temperature-conducting servo press guide rail structure based on heat pipe technology for rapid heat conduction.

[0004] To achieve the above objectives, this application provides a rapid heat conduction structure for a servo press guide rail based on heat pipe technology: It includes a hollow guide cylinder, inside which is an internal heat exchanger tube. The main body of the internal heat exchanger tube is a heat absorption coil that bends back and forth along the inner wall of the guide cylinder. One end of the heat absorption coil is a water inlet pipe, and the other end is connected to a drain pipe via an inner extension pipe. The water inlet pipe and the drain pipe extend in the same direction and are fitted with a heat insulation sleeve. A support tray is fixedly connected to the upper end of the guide cylinder, and a mounting base is fixedly connected to the lower end. The heat insulation sleeve is fixedly connected to the mounting base. Increasing the dimensions of the upper and lower ends of the guide cylinder reduces the contact pressure with the connecting components and limits the maximum sliding distance of the sliding components outside the guide cylinder.

[0005] As a preferred embodiment, the inner wall of the guide cylinder has an upper pipe clamp and a lower pipe clamp. The portion of the heat-absorbing coil near the support tray is clamped by the upper pipe clamp, and the portion of the heat-absorbing coil near the mounting base is clamped by the lower pipe clamp, thus constraining both the upper and lower ends of the inner heat-absorbing tube and keeping the inner heat-absorbing tube stable inside the guide cylinder.

[0006] As a preferred embodiment, there are several upper pipe clamps, which are equidistantly arranged around the axis of the guide cylinder; there are also several lower pipe clamps, which are equidistantly arranged around the axis of the guide cylinder to form a ring-shaped constraint structure.

[0007] As a preferred embodiment, the upper pipe clamp, the lower pipe clamp, and the guide cylinder are an integral structure made of alloy steel, which has good wear resistance and thermal conductivity.

[0008] As a preferred embodiment, the heat insulation sleeve includes a long sleeve with a through hole extending through both ends, suitable for the drain pipe to pass through; the outer side of the long sleeve has a limiting sleeve with a short through hole extending through both ends, suitable for the inlet pipe to pass through, preventing the coolant in the inlet pipe from exchanging heat with the coolant in the drain pipe.

[0009] As a preferred embodiment, the long sleeve and the limiting sleeve are an integral structure made of foam material, and the densely distributed closed pores can effectively prevent heat conduction.

[0010] As a preferred embodiment, the upper surface of the mounting base is provided with an embedded annular groove, the lower end of the guide cylinder is adapted to be embedded in the embedded annular groove, and the mounting base also has an embedded disc within the embedded annular groove, adapted to be embedded in the guide cylinder; the upper surface of the embedded disc is provided with a through groove penetrating the lower surface of the mounting base, adapted for the heat insulation sleeve to pass through; the portion of the mounting base outside the embedded annular groove is provided with a lower connecting hole, through which bolts and other connecting parts pass to fix the mounting base to the top housing of the servo press.

[0011] As a preferred embodiment, the lower surface of the support tray has an upper collar, which is suitable for fitting around the upper end of the guide cylinder. The portion of the support tray outside the upper collar has an upper connecting hole, through which bolts and other connecting parts pass to be fixedly connected to the worktable of the servo press.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By setting a heat-absorbing coil structure on the inner wall of the hollow guide tube, the heat conducted inward by the cooling water is quickly carried away. Only a suitable amount of lubricating oil needs to be coated on the outer surface of the guide tube. Not only is the cooling efficiency high, but the surface of the guide rail can also be kept clean. (2) By designing a pipe clamp structure on the inner wall of the guide tube, not only can heat be conducted efficiently, but the installation stability of the internal heat exchange tube can also be well maintained.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-10 The servo press guide rail rapid heat conduction structure based on heat pipe technology shown includes a hollow guide cylinder 1. An internal heat exchanger 5 is installed inside the guide cylinder 1. Coolant, such as water, needs to be circulated through the internal heat exchanger 5 to effectively remove heat from the guide cylinder 1. The main body of the internal heat exchanger 5 is a heat absorption coil 503 that bends back and forth along the inner wall of the guide cylinder 1. The heat absorption coil 503 is very close to the inner wall of the guide cylinder 1, allowing for efficient heat conduction. To ensure the installation stability of the internal heat exchanger 5, the inner wall of the guide cylinder 1 also needs to have an upper pipe clamp. The guide cylinder 1 has several upper pipe clamps 101 and lower pipe clamps 102. These upper pipe clamps 101 are arranged equidistantly around the axis of the guide cylinder 1. There are also several lower pipe clamps 102, which are also arranged equidistantly around the axis of the guide cylinder 1. Normally, the number of upper pipe clamps 101 and lower pipe clamps 102 corresponds, and their projections on the horizontal plane coincide. The upper pipe clamps 101, lower pipe clamps 102, and guide cylinder 1 are an integral structure made of alloy steel to ensure heat conduction efficiency and improve the heat absorption and cooling effect.

[0029] The portion of the heat absorption coil 503 near the support tray 3 is engaged by the upper pipe clamp 101, and the portion of the heat absorption coil 503 near the mounting base 4 is engaged by the lower pipe clamp 102. In this way, both the upper and lower ends of the internal heat exchange tube 5 are constrained by the annularly arranged pipe clamps, which can maintain stability well in the guide cylinder 1.

[0030] One end of the heat absorption coil 503 is a water inlet pipe 501, and the other end is connected to a drain pipe 502 through a horizontal inner extension pipe 504. The water inlet pipe 501 and the drain pipe 502 extend in the same direction, usually vertically downward. The water inlet pipe 501 and the drain pipe 502 are jointly fitted with a heat insulation sleeve 2. The heat insulation sleeve 2 includes a long sleeve 201, which has a long through hole 203 through both ends for the drain pipe 502 to pass through. The outer side of the long sleeve 201 has a limiting sleeve 202 at the lower end, which has a short through hole 204 through both ends for the water inlet pipe 501 to pass through. The long sleeve 201 and the limiting sleeve 202 are an integral structure made of foam material. The foam material has closed pores inside, which can effectively isolate the heat exchange between the water inlet pipe 501 and the drain pipe 502.

[0031] The upper end of the guide cylinder 1 is fixedly connected to the support plate 3. The lower surface of the support plate 3 has an upper collar 301 for fitting around the upper end of the guide cylinder 1. The part of the support plate 3 outside the upper collar 301 has an upper connecting hole 302 for bolts and other connecting parts to pass through, so as to fix the support plate 3 to the top housing of the servo press.

[0032] The lower end of the guide cylinder 1 is fixedly connected to the mounting base 4, and the heat insulation sleeve 2 is also fixedly connected to the mounting base 4. Specifically, the upper surface of the mounting base 4 is provided with an embedded annular groove 401, and the lower end of the guide cylinder 1 is precisely embedded in the embedded annular groove 401. The mounting base 4 also has an embedded disc 403 in the embedded annular groove 401, which is embedded in the guide cylinder 1. The upper surface of the embedded disc 403 is provided with a through groove 402 that penetrates the lower surface of the mounting base 4, for the heat insulation sleeve 2 to pass through and be fixed. The part of the mounting base 4 outside the embedded annular groove 401 is provided with a lower connecting hole 404, for bolts and other connecting parts to pass through, and to fix the mounting base 4 to the servo pressure worktable.

[0033] Working principle: During use, the inlet pipe 501 and the drain pipe 502 are connected to the output and input ends of the cooling water circulation equipment below the servo press. Low-temperature cooling water flows into the heat absorption coil 503 through the inlet pipe 501. The heat generated by friction on the outer surface of the guide cylinder 1 is conducted to the heat absorption coil 503 through the metal upper pipe clamp 101 and lower pipe clamp 102, and then absorbed by the cooling water. The heated cooling water flows to the drain pipe 502 through the upper horizontal inner extension pipe 504, and then flows back to the external cooling water circulation equipment. Since the heat of the guide cylinder 1 is carried away, the guide cylinder 1 can maintain a suitable working temperature for a long time even under high load.
