Description

Technical Field

[0001] This utility model relates to the technical field of copper tube processing equipment, specifically to a high-efficiency tube shrinking machine. Background Technology

[0002] In metal processing and pipe manufacturing, necking is an important processing technique. Its main purpose is to reduce the end diameter of copper pipes to the required size, thereby improving the tightness and stability of the pipe connection and providing a good foundation for subsequent threading.

[0003] In conventional processes, copper tubes must first be clamped and fixed before being tapered. However, current traditional tapering machines often use grippers or similar structures to hold the copper tubes. This clamping method reveals significant shortcomings when dealing with short, small-diameter tubes. Due to the small diameter of these tubes, the grippers struggle to achieve a stable and precise hold, frequently resulting in unstable clamping or misalignment. This directly leads to the tapering effect failing to meet expectations, resulting in low product yield and hindering production efficiency, severely impacting the economic benefits and market competitiveness of related manufacturers.

[0029] See Figure 1A high-efficiency tube shrinking machine includes a feeding mechanism 100, a clamping mechanism 200, a shrinking mechanism 300, and a discharging mechanism 400. The feeding mechanism 100 stores copper tubes and feeds them to the clamping mechanism 200. The clamping mechanism 200 clamps the copper tubes, and the shrinking mechanism 300 shrinks the copper tubes clamped by the clamping mechanism 200. Finally, the discharging mechanism 400 discharges the copper tubes from the clamping mechanism 200.

[0030] See Figure 1-3 The feeding mechanism 100 includes a vibratory feeder 110 and a feeding channel 120. The vibratory feeder 110 is mounted on the machine base 500. The inlet end of the feeding channel 120 is connected to the outlet end of the vibratory feeder 110, and the outlet end of the feeding channel 120 faces the clamping mechanism 200. The vibratory feeder 110 orderly conveys oriented copper tubes to the feeding channel 120, and the copper tubes are output to the clamping mechanism 200 through the outlet end of the feeding channel 120. The feeding channel 120 extends from top to bottom, so that the copper tubes are output to the clamping mechanism 200 in a vertical position.

[0031] See Figure 1-3 The clamping mechanism 200 includes a first clamping assembly 210, a second clamping assembly 220, and a clamping drive 230. The first clamping assembly 210 is arranged below the discharge end of the feeding channel 120 and is opposite to the second clamping assembly 220. The first clamping assembly 210 is connected to the output end of the clamping drive 230. The clamping drive 230 drives the first clamping assembly 210 to move closer to or away from the second clamping assembly 220. When the first clamping assembly 210 and the second clamping assembly 220 are close together, the first clamping assembly 210 and the second clamping assembly 220 clamp the copper tube. In this embodiment, the clamping drive 230 is a cylinder.

[0032] The first clamping assembly 210 includes a first clamping base 211, a first clamping head 212, and a first supporting head 213. The first clamping base 211 is connected to the output end of the clamping drive unit 230. The first clamping head 212 and the first supporting head 213 are mounted on the side of the first clamping base 211 facing the second clamping assembly 220, with the first clamping head 212 positioned directly above the first supporting head 213. The length of the first supporting head 213 is greater than the length of the first clamping head 212. The first clamping base 211 is a slider structure and is slidably mounted on the machine base 500 via a slide rail, ensuring the stability and orientation of the first clamping base 211's movement, thereby guaranteeing the stability of the clamping. The end of the first clamping head 212 facing the second clamping assembly 220 has a first clamping position 2121, which is a semi-circular groove structure adapted to the copper tube. The first material support head 213 has a baffle part 2131 on one end facing the second clamping assembly 220. The baffle part 2131 is a raised elongated structure.

[0033] The second clamping assembly 220 includes a second clamping base 221 and a second clamping head 222. The second clamping base 221 is mounted on the machine base 500, and the second clamping head 222 is mounted on the side of the second clamping base 221 facing the first clamping assembly 210. The end of the second clamping head 222 facing the first clamping assembly 210 has a second clamping position 223, which is a semi-circular groove structure adapted to the copper tube.

[0034] In practical application: First, the clamping drive 230 drives the first clamping base 211 to move the first clamping head 212 and the first supporting head 213, so that the first clamping position 2121 is aligned with the discharge end of the feeding channel 120. The copper tube output from the discharge end of the feeding channel 120 falls into the first clamping position 2121 under the action of gravity. The bottom end of the copper tube is supported by the first supporting head 213 and blocked by the blocking part 2131, thereby restricting the copper tube in the first clamping position 2121. In clamping position 2121; then, clamping drive 230 drives the first clamping base 211 to move the first clamping head 212 and the first supporting head 213 so that the first clamping head 212 and the second clamping head 222 are close together; at this time, the copper tube is between the first clamping position 2121 and the second clamping position 223, and the first clamping position 2121 and the second clamping position 223 cooperate to clamp the copper tube; then, the necking mechanism 300 performs necking treatment on the copper tube.

[0035] See Figure 1-3 The necking mechanism 300 includes a necking drive 310 and a necking die 320. The necking drive 310 is mounted on the machine base 500 via a necking mounting base. The necking die 320 is connected to the output end of the necking drive 310, and the necking end of the necking die 320 faces the clamping mechanism 200. Specifically, the necking die 320 is arranged above the second clamping assembly 220, and the necking end of the necking die 320 faces the second clamping position 223. In application, after the first clamping position 2121 and the second clamping position 223 cooperate to clamp the copper tube, the necking drive 310 drives the necking die 320 to move to the end of the copper tube to perform necking treatment on the end of the copper tube. In this embodiment, the necking drive 310 is a motor.

[0036] See Figure 1-3The unloading mechanism 400 includes an unloading drive 410 and an unloading pusher 420. The unloading drive 410 is mounted on the machine base 500, and the unloading pusher 420 is connected to the output end of the unloading drive 410. The unloading drive 410 drives the unloading pusher 420 to move. In application, after the necking mechanism 300 completes the necking process of the copper tube, the clamping drive 230 drives the first clamping base 211 to move the first clamping head 212 and the first supporting head 213 back, so that the first clamping position 2121 is opposite to the unloading pusher 420. The unloading drive 410 drives the unloading pusher 420 to move towards the first clamping position 2121, pushing the copper tube away from the first clamping position 2121 for unloading.

[0037] Preferably, the actuation path of the unloading mechanism 400 forms an acute angle with the actuation path of the first clamping assembly 210, that is, the moving path of the unloading pusher forms an acute angle with the moving path of the first clamping head 212. This facilitates the unloading pusher 420 in pushing the copper tube away from the first clamping position 2121 for unloading. The unloading pusher 420 includes two pushing parts 421, which are arranged vertically to push the copper tube from different positions, thereby improving the reliability of the unloading.

[0038] The following describes the working process of this high-efficiency flaring machine:

[0039] First, the clamping drive unit 230 drives the first clamping base 211 to move the first clamping head 212 and the first supporting head 213 so that the first clamping position 2121 is aligned with the discharge end of the feeding channel 120.

[0040] Next, the vibratory feeder 110 orderly conveys the oriented copper tubes to the feeding channel 120, and the copper tubes are output to the first clamping position 2121 through the discharge end of the feeding channel 120.

[0041] Next, the clamping drive unit 230 drives the first clamping base 211 to move the first clamping head 212 and the first supporting head 213 so that the first clamping head 212 and the second clamping head 222 are close together, and the first clamping position 2121 and the second clamping position 223 cooperate to clamp the copper tube.

[0042] Then, the necking drive 310 drives the necking mold 320 to move to the end of the copper tube to perform necking treatment on the end of the copper tube.

[0043] After the necking process is completed, the clamping drive unit 230 drives the first clamping base 211 to move the first clamping head 212 and the first supporting head 213 so that the first clamping position 2121 is opposite to the unloading push head 420. The unloading drive unit 410 drives the unloading push head 420 to move towards the first clamping position 2121, pushing the copper tube away from the first clamping position 2121 for unloading.

[0044] This completes the feeding, clamping, necking, and unloading of a copper tube. The unloading drive 410 drives the unloading pusher 420 to retract, and the clamping drive 230 drives the first clamping base 211 to retract the first clamping head 212 and the first supporting head 213, preparing for the processing of the next copper tube.

[0045] In summary, this high-efficiency tube shrinking machine optimizes the layout of the feeding, clamping, shrinking, and unloading mechanisms, resulting in a compact overall structure and a shortened processing path, thus improving production efficiency. It is particularly suitable for processing copper tubes with small diameters and short lengths. Furthermore, the optimized layout reduces the overall machine size and floor space required, making the equipment more flexible and efficient in space utilization, meeting the demands of modern production for high efficiency, energy saving, and space optimization.
