Description

Technical Field

[0001] This utility model mainly relates to the field of copper tube processing technology, specifically a copper tube unloading tool. Background Technology

[0002] Copper tubes, with their excellent thermal conductivity, ductility, and corrosion resistance, are widely used in critical fields such as refrigeration, HVAC, power, and automotive manufacturing, serving as indispensable fluid transmission components in numerous industrial equipment and systems. In these industries, copper tubes typically undergo precision cutting and bending processes. In automated continuous processing lines for copper tubes (especially shorter diameter tubes), the cut copper tubes slide at high speed through discharge troughs or chutes under gravity, ultimately completing unloading and collection.

[0003] However, the traditional method commonly used in copper pipe unloading currently involves placing a collection box or material frame directly below the equipment's discharge port. This seemingly simple method has significant technical drawbacks: when the copper pipe slides out from the end of the discharge trough, which has a certain height, it accumulates a large terminal velocity due to gravity, generating strong impact kinetic energy. When the high-speed falling copper pipe directly impacts the hard bottom or wall of the collection box, the lack of an effective buffer or deceleration mechanism inevitably leads to a violent impact. The direct impact of the high-speed falling copper pipe on the collection box causes a series of damages: the pipe body deforms and becomes elliptical due to instantaneous stress; the surface is scratched, abraded, and dented due to collisions and friction with the box wall or other copper pipes; and the ends develop curled edges, burrs, and crushing. These damages affect the quality of the copper pipe, therefore, there is an urgent need to develop a copper pipe unloading fixture to solve these problems. Utility Model Content

[0004] This utility model provides a solution that addresses the problem of overly simplistic existing technical solutions. It offers a significantly different approach, primarily providing a copper pipe unloading fixture. This fixture addresses the issue mentioned in the background section where copper pipe unloading often involves placing a collection box directly below the equipment's outlet. This method has significant drawbacks: when the copper pipe slides out of the discharge chute, it accumulates a large terminal velocity due to gravity, resulting in strong impact kinetic energy. Furthermore, the lack of a buffering and deceleration mechanism leads to high-speed impacts on the collection box, causing pipe deformation, ellipticization, surface scratches, abrasions, dents, end curling, burrs, and crushing, all of which affect quality.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A copper pipe unloading fixture includes a box body, a guide plate installed on the upper part of the box body, a connecting rod provided on the inner wall of the box body, a movable plate rotatably connected to the outer wall of the connecting rod via an mounting block, and a counterweight block installed on the bottom of the movable plate near the left side.

[0006] More preferably, the bottom of the box is equipped with a base plate for supporting the box, and a sliding tube is installed at each of the four corners of the bottom of the base plate. A fixed tube is slidably sleeved on the outer wall of each sliding tube. A screw hole is opened on the outer wall of the fixed tube near the top, and a plurality of equally spaced screw holes are opened on the sliding tube. The fixed tube and the sliding tube are connected by screws, which can be used to adjust the height of the tooling according to the tooling usage requirements.

[0007] More preferably, the guide plate is provided with a barrier, the barrier is L-shaped, and both the guide plate and the movable plate are provided with cushioning rubber pads.

[0008] In a further preferred embodiment, a hanging ring is installed at the bottom of the movable plate near the corner, and a connecting rope is installed on one side of the box body. One end of the connecting rope is connected to a hook, and the hook engages with the hanging ring.

[0009] More preferably, the box body is L-shaped, and an opening is provided on one side; one end of the movable plate extends to the outside of the opening of the box body, and baffles are provided at both ends of the opening of the box body.

[0010] More preferably, both the movable plate and the box body are provided with buffer rubber strips at the contact points.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This copper tube unloading fixture, through the setting of a buffer guide plate and a rotatable movable plate controlled by a counterweight, and the buffer rubber pads on the guide plate and movable plate, can absorb impact energy in multiple stages, so that the speed of the copper tube gradually decreases during the sliding process, preventing instantaneous stress deformation, surface scratches and end damage caused by high-speed impact. It avoids damage such as deformation, scratches and dents caused by direct high-speed impact of the copper tube into the collection box. The counterweight design of the movable plate (the number of counterweight blocks can be adjusted) ensures that the copper tube is released smoothly after accumulating a certain amount of gravity, thereby improving the quality and integrity of copper tube collection, while realizing an automated and adjustable unloading process to meet the needs of continuous processing.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text.

[0017] Please refer to the appendix carefully. Figure 1-3 A copper pipe unloading fixture includes a housing 1, a guide plate 5 installed on the upper part of the housing 1, a connecting rod 6 provided on the inner wall of the housing 1, and a movable plate 8 rotatably connected to the outer wall of the connecting rod 6 via a mounting block 7; a plurality of counterweights 9 are installed on the bottom of the movable plate 8 and near the left side by screws (the horizontal distance between the center of the counterweight 9 and the rotation axis of the mounting block 7 is L1, the horizontal distance between the center of the copper pipe bearing area of ​​the movable plate 8 and the rotation axis is L2, and L1·M ≥ k·L2·G (M is the total mass of the counterweights, G is the weight of a single copper pipe, and k is a safety factor ≥1.2)).

[0018] In this embodiment, as Figure 1 and Figure 2 As shown, a base plate 2 for supporting the box 1 is installed at the bottom of the box 1. Sliding tubes 3 are installed at the four corners of the bottom of the base plate 2. A fixed tube 4 is slidably fitted on the outer wall of each sliding tube 3. A screw hole is opened on the outer wall of the fixed tube 4 near the top. A number of equally spaced screw holes are opened on the sliding tube 3. The fixed tube 4 and the sliding tube 3 are connected by screws. The height of the tooling can be adjusted according to the height of the discharge port of the copper tube processing equipment by sliding the sliding tube 3 and the fixed tube 4 and screw locking, which improves the adaptability of the tooling in different usage scenarios.

[0019] In this embodiment, as Figure 1 and Figure 2As shown, a barrier 13 is provided on the guide plate 5. The barrier 13 is L-shaped, and the guide plate 5 is tilted. When the copper pipe falls from above the rear end of the tooling onto the guide plate 5, the copper pipe will slide forward. At this time, the barrier 13 can act as a stop. Both the guide plate 5 and the movable plate 8 are equipped with buffer rubber pads. The buffer rubber pads on the guide plate 5 and the movable plate 8 can buffer the falling copper pipe.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a hanging ring 10 is installed at the bottom of the movable plate 8 near the corner, and a connecting rope 11 is installed on one side of the box body 1. One end of the connecting rope 11 is connected to a hook 12, which is engaged with the hanging ring 10. When the hook 12 is engaged with the hanging ring 10, the movable plate 8 and the box body 1 are closed, which facilitates subsequent unloading. During normal use, the hook 12 can be separated from the hanging ring 10.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, the box 1 is L-shaped with an opening on one side; one end of the movable plate 8 extends to the outside of the opening of the box 1, and baffles are provided at both ends of the opening of the box 1; when the copper tube falls onto the guide plate 5, it will slide down from the guide plate 5 onto the movable plate 8, and then the copper tube will slide down. When multiple copper tubes accumulate, the movable plate 8 will rotate due to gravity and separate from the box 1. At this time, the copper tube will slide out through the opening of the box 1, and the baffles can block it, ensuring that the copper tube can fall into the collection box below the opening of the box 1.

[0022] In this embodiment, as Figure 2 and Figure 3 As shown, buffer rubber strips are provided at the contact points between the movable plate 8 and the box 1. When the copper tube slides off the movable plate 8, the movable plate 8 rotates under the action of the counterweight 9 and closes with the opening of the box 1. At this time, the movable plate 8 contacts the box 1, and the buffer rubber strips at the contact points can play a buffering role to reduce the impact of the collision.

[0023] The specific operating procedure of this utility is as follows: First, according to the height of the discharge port of the copper tube processing equipment, the relative position of the sliding tube 3 and the fixed tube 4 is adjusted, and the overall height of the fixture is adjusted by using screws to lock it in place, so that the fixture meets the usage scenario. After the adjustment is completed, the fixture is in the ready-to-work state. At this time, the hook 12 and the hanging ring 10 are kept separate. Then, a collection box is placed on the bottom plate 2 below the opening of the box 1 to prepare to receive the sliding copper tube. When the copper tube falls from the discharge port of the copper tube processing equipment above the rear end of the tooling, it will first fall onto the inclined guide plate 5. Due to the inclined design of the guide plate 5, the copper tube will roll to the left along the guide plate 5. The L-shaped enclosure 13 can prevent the copper tube from slipping off the side of the guide plate 5. At the same time, the buffer rubber pad on the guide plate 5 will cushion the falling copper tube and reduce the collision damage between the copper tube and the guide plate 5. Subsequently, the copper tube slides from the guide plate 5 onto the movable plate 8. The buffer rubber pad on the movable plate 8 also cushions the copper tube. Then, because the movable plate 8 is in an inclined state, the copper tube rolls on the movable plate 8. As the copper tube continues to accumulate in the upper and lower parts of the movable plate 8, when the weight of the copper tube exceeds the balancing force of the counterweight 9, the movable plate 8 will rotate around the connecting rod 6 through the rotating connection point formed by the mounting block 7, and separate from the box 1. When the movable plate 8 rotates to a certain extent, the collected copper tubes will slide off the movable plate 8 and slide out through the opening of the box 1. The baffles at both ends of the opening of the box 1 will block and guide the sliding copper tubes, ensuring that the copper tubes can fall into the collection box below the opening of the box 1. After the copper tube slides down, the movable plate 8 rotates in the opposite direction under the gravity of the counterweight 9, gradually closing with the opening of the box 1. At the moment the movable plate 8 contacts the box 1, the buffer rubber strip at the contact point will play a buffering role, reducing the impact of the collision and preventing damage to the components due to the collision. When the collection box is full and needs to be replaced with an empty one, hold down the movable plate 8, then engage the hook 12 with the hanging ring 10 at the bottom of the movable plate 8. This keeps the movable plate 8 and the box body 1 in a relatively closed state, facilitating the replacement of the collection box. After the collection box is replaced, separate the hook 12 from the hanging ring 10, and the tooling will return to normal operation. Furthermore, depending on actual work requirements, the balance of the movable plate 8 can be adjusted by removing or installing counterweights 9 at the bottom of the movable plate 8, changing the number of counterweights 9, or installing counterweights 9 of different weights. This adapts to different work needs.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
