Description

Technical Field

[0001] This utility model belongs to the technical field of copper tube bending machines, specifically relating to an automatic copper tube bending machine. Background Technology

[0002] In the field of copper tube processing, automatic bending machines are widely used in the copper tube forming process of industries such as air conditioning, refrigeration, and sanitary ware. However, existing equipment has obvious shortcomings in actual use: when the bent copper tubes fall into the collection box through the discharge plate, they tend to accumulate on one side, requiring frequent manual sorting to prevent them from falling, increasing labor costs and affecting continuity; during the rolling process, the copper tubes lack effective cushioning and are prone to scratches or deformation due to impact and friction, reducing product quality; the collection box is tightly connected to the receiving mechanism, and multiple parts need to be disassembled when changing them, which is cumbersome and time-consuming; at the same time, the traditional receiving mechanism cannot adapt to the weight and rolling speed of copper tubes of different specifications, which can easily lead to receiving deviation or jamming, resulting in more manual intervention, lower pass rate, and longer downtime for changing materials, which restricts the intelligent upgrading and efficiency improvement of the production line. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic copper tube bending machine to solve the problem mentioned in the background art that the copper tube bending machine cannot buffer and protect the bent copper tube during discharge.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic copper tube bending machine, comprising a base, a bending cylinder fixed to the top of the base, a movable clamping manipulator fixed to one side of the top of the base relative to the bending cylinder, a discharge plate fixed to the inner side of the top of the base relative to the bending cylinder and the movable clamping manipulator, and a pushable uniform material receiving component provided on the surface of the base, the pushable uniform material receiving component comprising a fixing plate fixed to the surface of the base and a placement plate provided on the top of the fixing plate, the top of the placement plate being provided with a collection box.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 5 This utility model provides a technical solution: an automatic copper tube bending machine, including a base 1, a bending cylinder 2 fixed to the top of the base 1, a movable clamping manipulator 3 fixed to one side of the top of the base 1 relative to the bending cylinder 2, a discharge plate 4 fixed to the inner side of the top of the base 1 relative to the bending cylinder 2 and the movable clamping manipulator 3, and a pushable uniform material receiving component provided on the surface of the base 1. The pushable uniform material receiving component includes a fixing plate 100 fixed to the surface of the base 1 and a placement plate 101 set on the top of the fixing plate 100. A collection box 102 is set on the top of the placement plate 101. By setting the pushable uniform material receiving component (fixed plate, placement plate, collection box), the copper tubes after bending are collected in a concentrated manner, avoiding random scattering of the copper tubes, laying the foundation for subsequent uniform sorting and quick replacement of the collection box, and improving the orderliness of the material receiving process.

[0015] In this embodiment, preferably, a fixing seat 200 is symmetrically fixed to the top of the fixing plate 100, and an internal groove 201 is opened at the top of the fixing seat 200. A lifting rod 202 embedded in the internal groove 201 is symmetrically fixed to the bottom of the placement plate 101. The lifting rod 202 is slidably connected to the internal groove 201. A telescopic spring 203 connected to the lifting rod 202 is fixed inside the internal groove 201. The combination of the fixing seat, the internal groove, the lifting rod and the telescopic spring enables the placement plate to have an elastic lifting function, which can adapt to the weight change of the copper tube in the collection box. At the same time, it provides a convenient lifting and adjustment structure for replacing the collection box and reduces the operating resistance during replacement.

[0016] In this embodiment, preferably, a guide groove 300 is provided through the surface of the lifting rod 202, and a guide block 301 that passes through the guide groove 300 is fixed inside the built-in groove 201. The guide block 301 is engaged with the guide groove 300. The engagement between the guide groove and the guide block provides precise guidance for the sliding of the lifting rod, avoids the placement plate from shifting or shaking during the lifting process, ensures the stability of the collection box position, and improves the positioning accuracy of the receiving material.

[0017] In this embodiment, preferably, a fixing screw 400 is fixed to the top of the fixing plate 100 relative to the inner side of the fixing base 200, and a screwing rod 401 is fixed to the bottom of the placement plate 101 relative to the inner side of the lifting rod 202. The bottom of the screwing rod 401 is provided with an internal thread, and the screwing rod 401 is screwed to the fixing screw 400 through the internal thread. The screwing structure of the fixing screw and the screwing rod can rigidly support and lock the placement plate through thread adjustment. Combined with the elastic lifting structure, double fixing is achieved, which not only ensures the stability when receiving materials, but also facilitates quick unlocking when replacing the collection box.

[0018] In this embodiment, preferably, the surface of the base 1 is provided with a push plate 500 embedded inside the collection box 102, the interior of the base 1 is provided with a groove 501, the interior of the groove 501 is provided with a through hole 502 extending to the surface of the base 1, the interior of the groove 501 is fixed with a motor 503, the end of the motor 503 is provided with a push rod 504 that passes through the through hole 502 and connects to the push plate 500. The design of the push plate, motor and push rod realizes the automatic pushing and sorting of copper tubes in the collection box, avoids one-sided accumulation and falling, replaces manual stirring, reduces manual intervention, and improves the automation level of the collection process.

[0019] In this embodiment, preferably, the end of the push plate 500 is fixed with a material guiding buffer slope 600, and the top of the placement plate 101 is fixed with a baffle 601 that fits and connects with the collection box 102. The material guiding buffer slope guides the copper tube to fall smoothly into the collection box, reducing the impact of rolling. The baffle limits the collection box to ensure that the installation position of the collection box is accurate, avoids material receiving deviation, and improves the stability of equipment operation.

[0020] In this embodiment, preferably, the inside of the collection box 102 is provided with a buffer pad, and the surfaces of the discharge plate 4 and the guide buffer slope 600 are both fixed with rubber pads. The buffer pads and rubber pads inside the collection box can effectively absorb the impact force of the copper tube, avoid surface scratches and deformation, protect the processing quality of the copper tube, and reduce the scrap rate.

[0021] The working principle and usage process of this utility model are as follows: After the copper tube is clamped and fed into the bending cylinder 2 by the moving clamping robot 3 for bending, it is again clamped and placed on the top of the discharge plate 4 by the moving clamping robot 3. Then, the clamping claws are released, allowing the bent copper tube to roll from the discharge plate 4 into the collection box 102. When falling into the collection box 102, it is guided by the material guiding buffer slope 600. The rubber pads on the surface of the collection box 102 and the material guiding buffer slope 600 can protect the copper tube from rolling. At the same time, the buffer pads can cushion the copper tube when it falls into the collection box 102. To avoid scratching or damaging the surface of the copper pipes, since the bent copper pipes that fall into the collection box 102 will accumulate on one side of the collection box 102, the timed motor 503 extends the length of the push rod 504, allowing the push rod 504 to slide inside the through hole 502 and push the push plate 500 to move from left to right inside the collection box 102, thus moving the copper pipes accumulated on the left side of the collection box 102 to the right side. This achieves even distribution of the copper pipes inside the collection box 102, preventing them from falling due to excessive accumulation. This eliminates the need for manual manipulation of the accumulated copper pipes, reducing human intervention. When the collection box 102... After the copper tubes inside 02 are full, loosen the screwing rod 401, allowing it to rotate on the surface of the fixing screw 400 via its internal thread. This causes the screwing rod 401 to separate downwards from the bottom end of the placement plate 101, releasing the support and lifting function of the bottom end of the placement plate 101. Then, press down on the collection box 102, causing it to move the placement plate 101 into the interior groove 201 via the lifting rod 202. This compresses the telescopic spring 203, causing it to deform and simultaneously causing the guide groove 300 to slide on the surface of the guide block 301, thus guiding the movement. This allows the collection box 102 to separate from the push plate 500. Then, pull out the collection box 102 and replace it with an empty collection box 10. 2. Place the empty collection box 102 on top of the placement plate 101 and block and limit it with the baffle 601. Then release the pressed collection box 102. At this time, the lifting rod 202 moves upward inside the built-in groove 201 under the action of the telescopic spring 203, which can drive the placement plate 101 and the collection box 102 to move upward, so that the push plate 500 is embedded in the inside of the collection box 102. Then twist the screwing rod 401 in the opposite direction, so that the screwing rod 401 moves upward through the internal thread on the surface of the fixing screw 400. When the top of the screwing rod 401 is attached to the bottom of the placement plate 101, it can play a supporting and lifting role, so as to collect the bent copper pipe.
