Description

Technical Field

[0001] This invention relates to a low-volatility heat tracing pipe quantitative cutting tool and its usage method. Background Technology

[0002] Heat tracing pipes, as highly efficient heat transfer devices, are widely used in the heat dissipation systems of electronic products. Traditional heat tracing pipe structures mostly use copper heat pipes. However, with technological advancements, higher demands are placed on heat dissipation performance, which copper heat pipes can no longer meet. To further improve heat dissipation, a new type of heat tracing pipe using a low-volatility working medium has been developed. Compared to copper heat pipes, low-volatility working medium heat tracing pipes have advantages such as high thermal conductivity and lighter weight.

[0003] Traditional cutting equipment relies on manual visual inspection and measurement to measure the length of heat tracing pipes. At the same time, it lacks a processing device for further refining the surface of the pipes. The pipes are prone to bending during daily processing, making it difficult to guarantee the accuracy of subsequent cutting. This leads to an increase in the positional deviation of the low-volatility heat tracing pipes when installed on the radiator, affecting the matching and assembly with the radiator, reducing the tightness of the heat pipe and the radiator, and thus affecting the heat dissipation effect.

[0004] Therefore, a low-volatility heat tracing pipe quantitative cutting tool and its application method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a low-volatility heat tracing pipe quantitative cutting tool and its usage method to solve the problems mentioned in the background art.

[0009] One side of the cutting groove is provided with a rolling assembly for straightening low-volatility heat tracing pipes, and both sides of the support plate are provided with clamping assemblies for connecting to the workbench.

[0010] The low-volatility heat tracing pipe is fed to the winding device via the placement groove, the limiting component, and the rolling component. The cutting blade cuts it through the cutting groove.

[0011] Preferably, the limiting component includes connecting seats disposed on both sides of the bearing plate, the connecting seats having limiting grooves on both sides inside, bearing ring plates slidably connected inside the limiting grooves, and a limiting roller for connecting to a low-volatility heat tracing pipe is connected between the two sets of bearing ring plates inside the connecting seats.

[0012] The limiting roller has a limiting groove in the middle, and the limiting groove is located directly above the placement groove.

[0013] Preferably, the upper part of the bearing ring plate is provided with a spring for elastic movement of the bearing ring plate.

[0014] Preferably, the horizontal distance between the limiting component and the cutting groove is 1 meter.

[0015] Preferably, the rolling assembly includes a rolling table, a rolling groove is formed in the middle of the rolling table, multiple sets of support rods are arranged in the rolling groove, an inner groove is formed on one side of the multiple sets of support rods, and a rolling roller is arranged in the inner groove.

[0016] Both sides of the rolling groove are provided with limiting grooves for linear movement of the support rod.

[0017] Preferably, the rolling mill has an adjustment cavity and a limiting cavity on both sides, and an adjustment plate is connected inside the adjustment cavity and the limiting cavity.

[0018] The two sides of the multiple sets of support rods are respectively connected to the adjustment plates of the adjustment cavity and the limiting cavity.

[0019] The adjusting plate located in the adjusting cavity has a threaded groove in the middle, and the adjusting plate located in the limiting cavity has a through hole in the middle.

[0020] Preferably, the rolling table is set on an inclined surface on one side of the adjusting cavity, and an adjusting wheel is provided on one side of the inclined surface. The adjusting wheel is connected to the threaded groove through a screw.

[0021] Preferably, a limiting rod is provided inside the limiting cavity, and the limiting rod passes through the adjusting plate through the through hole.

[0022] Preferably, the clamping assembly includes a connecting plate, and a clamping plate is connected below the connecting plate.

[0023] The connecting plate is equipped with a rotating wheel, which is connected to the clamping plate via a lead screw. The clamping plate is equipped with multiple sets of anti-slip strips.

[0024] The inner side of the connecting plate is provided with a guide groove, and the clamping plate moves below the connecting plate through the guide groove.

[0025] A method for using a low-volatility heat tracing pipe quantitative cutting fixture includes the following steps:

[0026] Step A: Installation of tooling;

[0027] Step A1: Align the support plate with the support platform, push the support plate to move along both sides of the support platform until the connecting plates on both sides are in the middle of the support platform.

[0028] Step A2: Rotate the rotating wheel located above the connecting plate, so that it drives the clamping plate to move upward inside the guide groove through the screw, pressing the anti-slip strip against the underside of the support platform, and connecting the support plate to the support platform;

[0029] Step B: Installation of low-volatility heat tracing pipes;

[0030] Step B1: Rotate the adjusting wheel located on the rolling table. The adjusting wheel connecting screw rotates, and the screw cooperates with the threaded groove in the middle of the adjusting plate, causing the adjusting plate to move up. The adjusting plate connecting support rod moves upward along the limiting groove, so that the height of the rolling roller in the rolling groove increases.

[0031] Step B2: Place one end of the low-volatility heat tracing tube to be cut into the placement groove, and push the low-volatility heat tracing tube along the placement groove;

[0032] Step B3: The low-volatility heat tracing tube squeezes the limiting roller. The limiting roller moves upward through the bearing ring plate and squeezes the spring in the limiting groove. The spring contracts under force, the limiting roller moves upward, and then the low-volatility heat tracing tube passes through the limiting groove of the limiting roller.

[0033] Step B4: The elastic force generated by the spring contraction acts on the upper part of the low-volatility heat tracing tube through the limiting roller, squeezing and limiting the low-volatility heat tracing tube in the placement groove;

[0034] Step B5: Continue pushing the low-volatility heat tracing tube until it is below the first set of rolling rollers on the rolling table. Rotate the adjusting wheel in the opposite direction, and the connecting screw will rotate. The screw will cooperate with the threaded groove in the middle of the adjusting plate, causing the adjusting plate to move down. The connecting rod of the adjusting plate will move down along the limiting groove, so that the height of the rolling roller in the rolling groove is reduced, and it is squeezed and adhered to the outer circumference of the low-volatility heat tracing tube.

[0035] Step B6: Push the low-volatility heat tracing tube again until it passes through the rolling table and is wound onto the side of the winding device;

[0036] Step C: Cutting the low-volatility heat tracing pipe;

[0037] Step C1: As the low-volatility heat tracing pipe is inserted into the placement groove, it comes into contact with the limiting roller, causing the limiting roller to rotate. The displacement sensor is connected to the limiting roller and records the number of rotations R of the limiting roller.

[0038] Step C2: Measure the length D between the fiber roller and the cutting groove, and the diameter d of the limiting roller located in the limiting groove.

[0039] Step C3: Calculate the length L of the low-volatility heat tracing pipe using the following formula:

[0040] L=πdR-D;

[0041] The length L of the low-volatility heat tracing pipe is determined;

[0042] Step C4: Use a cutting tool to cut the low-volatility heat tracing pipe located at the cutting groove.

[0043] Compared with the prior art, the beneficial effects of the present invention are:

[0044] This invention uses a limiting roller and a displacement sensor to measure the length of a low-volatility heat tracing pipe, ensuring measurement accuracy. The displacement sensor and limiting component in the tooling can accurately measure the length of the low-volatility heat tracing pipe, avoiding the errors caused by traditional manual visual inspection or manual measurement.

[0045] The rolling assembly in the tooling can straighten the low-volatility heat tracing pipe, making its surface flatter and providing better cutting conditions, thereby improving cutting accuracy. At the same time, the straightening force can be adjusted by rotating the adjusting wheel to reduce the curvature of the heat tracing pipe.

[0046] The fixture is reasonably designed and easy to operate. By adjusting the rotating wheels and rolling assembly, the parameters and position of the fixture can be flexibly adjusted to meet the cutting needs of low-volatility heat tracing pipes of different specifications and sizes.

[0047] The limiting component can perform preliminary straightening of the heat tracing pipe, guide the direction of the heat tracing pipe's advance, and can adaptably adjust to heat tracing pipes of different diameters without the need for manual adjustment.

[0048] The clamping assembly is reasonably designed to tightly clamp the low-volatility heat tracing pipe quantitative cutting fixture and provide a stable fixing force to ensure that the fixture will not loosen or move during operation, maintain the stability of precise cutting, and quickly install the fixture in the appropriate position, reducing installation time and complexity.

[0079] Step A1: Align the bearing plate 1 with the bearing platform at the same height, push the bearing plate 1 so that it moves along both sides of the bearing platform until the connecting plates 501 on both sides are located in the middle of the bearing platform.

The screw 409 cooperates with the threaded groove 4071 in the middle of the adjusting plate 407, causing the adjusting plate 407 to move upward.

Rotate the adjusting wheel 408 in the opposite direction, and the connecting screw 409 rotates. The screw 409 and the threaded groove 4071 in the middle of the adjusting plate 407 cooperate with each other, driving the adjusting plate 407 to move down.

[0087] Step B6: Push the low-volatility heat tracing tube again until it is wound around the winding device side through the rolling table 401;

[0088] Step C: Cutting the low-volatility heat tracing pipe;

[0089] Step C1: As the low-volatility heat tracing pipe is inserted into the placement groove 101, it comes into contact with the limiting roller 203, causing the limiting roller 203 to rotate.

[0091] Step C3: Calculate the length L of the low-volatility heat tracing pipe using the following formula:

[0092] L=πdR-D;

[0093] The length L of the low-volatility heat tracing pipe is determined;

[0094] Step C4: Use a cutting knife to cut the low-volatility heat tracing pipe located at the cutting groove 102.

[0095] The present invention provides a low-volatility heat tracing pipe quantitative cutting fixture and its method of use, which have the following advantages:

[0096] This invention uses a limiting roller 203 and a displacement sensor 3 to measure the length of a low-volatility heat tracing pipe, ensuring measurement accuracy. The displacement sensor 3 and the limiting component 2 in the tooling can accurately measure the length of the low-volatility heat tracing pipe, avoiding the errors caused by traditional manual visual inspection or manual measurement.

[0097] The rolling assembly 4 in the tooling can straighten the low-volatility heat tracing pipe, making its surface flatter and providing better cutting conditions, thereby improving cutting accuracy. At the same time, the straightening force can be adjusted by rotating the adjusting wheel 408 to reduce the curvature of the heat tracing pipe.

[0098] The tooling is reasonably designed and easy to operate. By adjusting the rotating wheel 408 and the rolling assembly 4, the parameters and position of the tooling can be flexibly adjusted to meet the cutting needs of low-volatility heat tracing pipes of different specifications and sizes.

[0099] The limiting component 2 can perform preliminary straightening of the heat tracing pipe, guide the direction of the heat tracing pipe's advance, and can adaptably adjust to heat tracing pipes of different diameters without the need for manual adjustment.

[0100] The clamping assembly 5 has a simple structure and can tightly clamp the low-volatility heat tracing pipe quantitative cutting fixture, providing a stable fixing force to ensure that the fixture will not loosen or move during operation, maintaining the stability of precise cutting, and quickly installing the fixture in the appropriate position, reducing installation time and complexity.
