Description

Technical Field

[0001] The invention relates to the technical field of refrigeration copper tube processing, in particular to a meter weight adjustment device for forming an internally threaded copper tube. Background Art

[0002] In the field of refrigeration copper tube processing, internally threaded copper tubes are widely used in refrigeration equipment such as air conditioners and refrigerators due to their excellent heat exchange properties. During their production, meter weight (weight per meter of copper tube) is a crucial quality parameter. Precisely controlling the meter weight of internally threaded copper tubes is crucial for ensuring product performance, improving production efficiency, and reducing production costs.

[0003] In traditional internally threaded copper tube production, controlling the meter weight relies primarily on operator experience and initial equipment commissioning. During the production process, factors such as slight variations in raw material properties (such as fluctuations in copper purity or hardness), unstable processing parameters (such as changes in extrusion speed or pulling speed), and mold wear can cause the meter weight of the internally threaded copper tube to deviate from the preset standard. However, existing production equipment often lacks effective real-time monitoring and automatic adjustment mechanisms, making it difficult to quickly adjust when the meter weight deviates.

[0004] Manual adjustments are not only inefficient but also prone to unstable product quality due to the difficulty in precisely controlling the adjustment range. For example, over-adjustment can lead to uneven wall thickness in copper tubes, affecting their mechanical properties and heat exchange efficiency; while under-adjustment can prevent the micrometer weight from meeting standard requirements, resulting in scrap. Furthermore, frequent manual adjustments increase operator workload, reduce production efficiency, and hinder the implementation of large-scale automated production.

[0005] Therefore, we propose a device for adjusting the weight of an internally threaded copper tube to solve the above problems. Summary of the Invention

[0013] Beneficial effects of the present invention:

[0014] 1. Precisely adjust the meter weight: This invention uses a high-precision weighing sensor to measure the weight of the internally threaded copper tube in real time and transmits the signal to the PLC.

The top end of the outer wall of the connecting plate A15 is fixedly installed with a buffer plate 18 through the telescopic rod 16. The buffer spring 17 is sleeved on the outside of the telescopic rod 16. By starting the electric push rod A14, the telescopic end of the electric push rod A14 pushes the connecting plate A15 to displace, thereby adjusting the distance between the connecting plate A15 and the base plate 1.

Then, the internally threaded copper tube is placed on the surface of the transmission component 2, and the electric push rod B19 is started, so that the electric push rod B19 pushes the mounting cross plate 20 through its telescopic end to adjust the height, so that the distance between the mounting cross plate 20 and the conveyor belt 12 is adjusted, thereby adjusting the distance between the detection end of the high-precision weighing sensor 21 and the internally threaded copper tube on the surface of the conveyor belt 12, measuring the weight of the internally threaded copper tube in real time, and then transmitting the weight signal to the PLC. After receiving the weight signal, the PLC compares and analyzes it with the preset value, calculates the deviation between the current meter weight of the copper tube and the standard value, and according to the size and positive and negative of the deviation value, the PLC enables the adjustment motor 23 to work accordingly, and then the adjustment motor 23 drives the bidirectional screw through its output shaft. The rod 24 rotates inside the through slot 22 so that the adjusting block 25 is threadedly driven on the outside of the bidirectional screw 24, and at the same time, the connecting plate B26 arranged on the lower surface of the adjusting block 25 drives the insert cylinder 27 to move, thereby driving the insert plate 28 inserted and slidably installed inside the insert cylinder 27 to adjust the displacement, and at the same time, the fixing rod 30 drives the extrusion block 31 to move, adjusts the distance between the two extrusion blocks 31, realizes the extrusion of the internally threaded copper tube, changes the wall thickness of the internally threaded copper tube, and completes the adjustment of the meter weight of the internally threaded copper tube.
