Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, specifically a capillary copper tube straightening and cutting device. Background Technology

[0002] Copper and copper alloy capillary tubes, also known as copper capillary tubes, are seamless tubes produced by pressing and drawing. They are strong, corrosion-resistant, lightweight, have good thermal conductivity, and high low-temperature strength. They are commonly used in the manufacture of heat exchange equipment (such as condensers) and in the assembly of cryogenic pipelines in oxygen production equipment. Small-diameter copper capillary tubes are often used to transport pressurized liquids (such as in cooling systems, lubrication systems, and hydraulic systems) and as pressure measuring tubes in instruments.

[0003] Some capillary copper tubes used as connectors require the fabrication of supports and flaring. Before fabricating supports and flaring, the capillary copper tubes need to be straightened from their coiled state and cut to a suitable length. Currently, straightening and cutting are done manually, which is inefficient. Utility Model Content

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Example Please see Figures 1-4 This utility model provides a technical solution: A capillary copper tube straightening and cutting device is provided, which can realize the automatic straightening and cutting of capillary copper tubes, with good straightening effect, flat cutting surface, improved work efficiency and reduced labor costs.

[0020] The device includes a support platform 1, which is made of high-strength cast iron and provides stable support for the entire device. A vertical plate 2, made of steel plate, is welded onto the support platform 1 and is used to install various mechanisms. A straightening mechanism 3 is provided on the vertical plate 2 for straightening the capillary copper tube. A cutting mechanism 7 is provided on the vertical plate 2 for cutting the straightened capillary copper tube. A clamping mechanism 18 is provided on the cutting mechanism 7 for clamping the capillary copper tube during cutting.

[0021] The straightening mechanism 3 includes a first straightening mechanism 4 symmetrically arranged on the vertical plate 2. The first straightening mechanisms 4 are connected by a transmission gear set 9 and a first pulley set 10 to form a transmission structure. The first straightening mechanism 4 is composed of several transmission wheels, which are arranged in pairs and reversed by the transmission gear set 9, thereby conveying the capillary copper tube. A motor 12 is fixed on the support platform 1 by bolts. The output end of the motor 12 is connected to one of the first straightening mechanisms 4 to provide power. The symmetrically arranged first straightening mechanisms 4 are also connected by a second pulley set 11 to form a transmission structure, which drives the two first straightening mechanisms 4 to operate synchronously, thereby conveying the capillary copper tube.

[0022] The upright plate 2 is also provided with a second straightening mechanism 5 and a third straightening mechanism 6 in sequence. The second straightening mechanism 5 and the third straightening mechanism 6 are vertically distributed and straighten the capillary copper tube from different directions. The second straightening mechanism 5 and the third straightening mechanism 6 both include a mounting frame 13 set on the upright plate 2. The mounting frame 13 is provided with evenly distributed straightening wheels 14. The straightening wheels 14 are steel wheels with smooth surfaces and can rotate freely.

[0023] The cutting mechanism 7 includes a support frame 15 mounted on a support platform 1. The support frame 15 is a steel frame, and a drive cylinder 16 is fixed to it by bolts. The drive cylinder 16 is a hydraulic cylinder. A movable plate 17 is inserted into and slidably mounted inside the support frame 15. The movable plate 17 is connected to the drive rod of the drive cylinder 16 and can slide up and down under the drive of the drive cylinder 16. A cutting mechanism 19 is provided inside the movable plate 17. The cutting mechanism 19 consists of a high-speed rotating cutting blade, its fixed housing, and a drive motor.

[0024] The clamping mechanism 18 includes a linkage plate 20 evenly arranged under the bottom surface of the movable plate 17. A rod 21 is welded to one side of the linkage plate 20. Clamping plates 22 are symmetrically and evenly distributed on the support platform 1. A guide opening 23 is provided on the outer wall of the clamping plate 22. The rod 21 is inserted into the guide opening 23 and slidably installed. A clamping wheel 24 is provided on one side of the clamping plate 22. The clamping wheel 24 is a rubber wheel, which can avoid damaging the capillary copper tube.

[0025] The guide port 23 includes a straight section 25 and a guide section 26 connected to each other. The guide section 26 is inclined. A feeding plate 8 is provided on the support platform 1. The feeding plate 8 is an inclined steel plate used to guide the cut capillary copper tube to be fed.

[0026] In use, one end of the capillary copper tube in its coiled state is placed between the first straightening mechanisms 4. The motor 12 is started, driving one of the first straightening mechanisms 4 to rotate. Through the transmission gear set 9 and the first pulley set 10, the transmission wheels reverse direction, and through the transmission of the second pulley set 11, the two first straightening mechanisms 4 operate synchronously. The clamping force between them drives the capillary copper tube forward, simultaneously performing preliminary straightening. After exiting the first straightening mechanism 4, the capillary copper tube enters the second straightening mechanism 5. The second straightening mechanism 5... The straightening wheel 14 further straightens the capillary copper tube from one direction; then the capillary copper tube enters the third straightening mechanism 6, where the straightening wheel 14 again straightens the capillary copper tube from a direction perpendicular to the second straightening mechanism 5. After straightening by multiple sets of straightening mechanisms, the capillary copper tube reaches an ideal straight state. The straightened capillary copper tube continues to move below the cutting mechanism 7. When it reaches the set length, the drive cylinder 16 is activated, driving the movable plate 17 to slide downwards. The movable plate 17 drives the cutting mechanism 19 and the linkage plate 20 to move downwards synchronously. The moving plate 20 moves downward, causing the insertion rod 21 to slide within the guide opening 23. Initially, the insertion rod 21 moves within the guide section 26. Due to the inclination of the guide section 26, it pushes the clamping plate 22 to move towards each other. The clamping plate 22 drives the clamping wheel 24 to approach and clamp the capillary copper tube. When the insertion rod 21 slides to the straight section 25, the clamping plate 22 stops moving, and the clamping wheel 24 maintains the clamping state of the capillary copper tube. At the same time, the cutting mechanism 19 moves downward to cut the clamped capillary copper tube. During the cutting process, since both sides of the capillary copper tube are fixed by the clamping wheel 24, it will not move. To ensure a flat cut surface, after cutting, the drive cylinder 16 drives the movable plate 17 to reset upwards, which in turn moves the cutting mechanism 19, the linkage plate 20, and the insertion rod 21 upwards. The insertion rod 21 slides back from the straight section 25 to the guide section 26. The clamping plates 22 move away from each other under their own weight or the action of the reset mechanism. The clamping wheel 24 releases its clamping on the capillary copper tube. The cut capillary copper tube is no longer constrained and falls onto the feeding plate 8. It slides out and is collected through the feeding plate 8. The uncut part continues to move under the drive of the first straightening mechanism 4 for the next straightening and cutting operation.

[0027] In the straightening mechanism 3, the first straightening mechanism 4, driven by the motor 12 and the related transmission mechanism, not only clamps and transports the capillary copper tube, but also performs preliminary straightening; the straightening wheels 14 of the second straightening mechanism 5 and the third straightening mechanism 6 straighten the capillary copper tube from different directions in multiple directions, and achieve a good straightening effect through multiple sets of straightening.

[0028] The drive cylinder 16 of the cutting mechanism 7 drives the movable plate 17 to move down, which in turn drives the cutting mechanism 19 to cut the capillary copper tube. At the same time, the insertion rod 21 of the clamping mechanism 18 slides in the guide port 23, and the clamping plate 22 drives the clamping wheel 24 to clamp the capillary copper tube through the guide section 26. The straight section 25 ensures the clamping state during cutting, realizes stable clamping during cutting, and ensures that the cut surface is flat.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
