Description

Technical Field

[0001] The utility model relates to the technical field of fin tube rolling, in particular to a material receiving device for fin tube rolling. Background Art

[0002] Finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to its surface to increase the surface area (or internal surface area), so as to achieve the purpose of improving the heat exchange efficiency. In the processing and production of finned tubes, after the finned tubes are rolled out by the processing equipment, in order to facilitate the transmission to the subsequent process, a U-shaped groove material connection structure is generally adopted. This material connection method has the following shortcomings in the processing and production process:

[0003] 1. As the rolling thickness of the fins becomes thinner, the fin tubes move forward and rotate during the rolling process. As the rolling length increases, the swing becomes larger and larger. In addition, the contact area between the fin tubes and the U-shaped grooves is larger, which leads to more and more serious collisions between the fin tubes and the inner wall of the U-shaped grooves, resulting in more and more fins falling over.

[0004] 2. The U-shaped groove material connection method can only carry the finned tubes. When the finned tubes need to be transferred to the next process, they still need to be transported manually or with other lifting equipment, which undoubtedly seriously affects the processing and production efficiency of the finned tubes;

[0005] Therefore, a kind of material receiving device that can overcome above-mentioned deficiency is badly needed. Utility Model Content

[0006] In order to overcome the shortcomings of the background technology, the utility model discloses a material receiving device for fin tube rolling. The utility model can not only perform stable and efficient material receiving operations on fin tubes, effectively reduce the friction and lodging of fins on fin tubes, but also greatly facilitate the material unloading and transfer operations on fin tubes, thereby greatly improving the processing and production efficiency of fin tubes.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A material receiving device for fin tube rolling comprises several hangers arranged in a linear manner, the hangers are composed of a cylinder, a mounting seat and a clamping arm, two clamping arms arranged in a mirror-symmetrical manner are hingedly mounted on the lower part of the mounting seat, a cylinder for controlling the opening and closing of the two clamping arms is arranged on the upper part of the mounting seat, two limiting long plates parallel to the arrangement direction of the several hangers are arranged on the lower part of the several hangers, the two limiting long plates are detachably mounted on the inner sides of several clamping arms on the same side of the lower part of the several hangers, and the opposite surfaces of the two limiting long plates are both concave surfaces.

[0009] Furthermore, the mounting base includes a top plate, a movable plate, and a mounting plate. Two mounting plates perpendicular to and parallel to each other are provided on the lower surface of the top plate. A movable plate parallel to the top plate and capable of lifting adjustment is provided between the two mounting plates.

Connecting rods are provided between the two ends of the movable plate and the corresponding clamping arms below, and the two ends of the connecting rod are respectively hinged to the movable plate and the clamping arm.

[0010] Furthermore, the opposite surfaces of the two limiting long plates are adapted to the inner surfaces of the clamping arms.

[0013] Furthermore, a buffer section is provided at the lower end of the blanking rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: By using several linearly arranged lifting tools, not only can the feeding operation of the finned tubes be realized by the closing of the clamping arms at the lower part of the lifting tools, but also the subsequent transfer and blanking operation of the finned tubes is facilitated;

[0016] By arranging the blanking rods, the finned tubes can be guided and conveyed during blanking, realizing the slow rolling and blanking of the finned tubes, and avoiding the lodging and damage of the fins caused by the vertical dropping of the finned tubes;

[0017] By arranging the buffer section, the finned tubes can be buffered during blanking, avoiding the collision damage caused by excessive inertia when the finned tubes roll;

[0018] The present utility model can not only perform stable and efficient feeding operations on the finned tubes, effectively reduce the friction and lodging of the fins on the finned tubes, but also greatly facilitate the blanking and transfer operations of the finned tubes, greatly improving the processing and production efficiency of the finned tubes, reducing the labor intensity, and saving time and production costs.

[0025] Next, the technical solutions of the present utility model will be described in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, they are only corresponding to the accompanying drawings of the present utility model for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation.

[0026] Please refer to the attached instruction Figures 1-5 , the present utility model provides a technical solution:

[0027] Embodiment 1, a material receiving device for finned tube rolling, includes several lifting devices arranged linearly. The lifting device is composed of a cylinder 1, a mounting seat 2, and a clamping arm 3. Specifically, the mounting seat 2 includes a top plate 7, a movable plate 8, and a mounting plate 9. On the lower surface of the top plate 7, there are two mounting plates 9 perpendicular to and parallel to each other corresponding to the top plate 7. Between the two mounting plates 9, there is a movable plate 8 parallel to the top plate 7 and capable of lifting adjustment. At the lower side of the opposite surfaces of the two mounting plates 9, a thick pin 10 is rotatably installed. The upper ends of the two clamping arms 3 are both rotatably connected to the thick pin 10. Between the two ends of the movable plate 8 and the corresponding lower clamping arms 3, there is a connecting rod 11. The two ends of the connecting rod 11 are respectively hinged to the movable plate 8 and the clamping arm 3. The output end of the cylinder 1 drives the movable plate 8 to lift, and with the lifting of the movable plate 8, the two clamping arms 3 are driven to open and close by using the connecting rod 11;

[0028] There are two limiting long plates 4 arranged parallel to the arrangement direction of several lifting tools at the lower part of the several lifting tools. The two limiting long plates 4 are respectively installed inside several clamping arms 3 on the same side of the lower part of the several lifting tools. The opposite surfaces of the two limiting long plates 4 are both concave surfaces. When carrying out the finned tube feeding operation, move the several lifting tools to the output end of the finned tube processing equipment through a lifting device. Control the clamping arms 3 to close through the air cylinder 1 so that the two limiting long plates 4 are closed to form a storage groove for storing the finned tubes. With the processing and output of the finned tubes, the finned tubes move towards the storage groove between the two limiting long plates 4 and are clamped. The concave surfaces on the opposite surfaces of the two limiting long plates 4 can effectively reduce the collision of the finned tubes during movement and reduce the lodging of the fins. After the feeding is completed, the finned tubes can be lifted to the next process by the lifting tool, and then the clamping arms 3 are opened to complete the blanking operation.

[0029] Embodiment 2: In order to facilitate the replacement of the limiting long plates 4 with different sizes to meet the feeding operations of different finned tubes and to meet the normal use of the lifting tools, the two limiting long plates 4 and the clamping arms 3 are detachably installed. Specifically, several connecting ear plates 13 arranged at intervals in the length direction of the limiting long plates 4 are provided on the opposite surfaces of the two limiting long plates 4. Through holes 14 are provided on the connecting ear plates 13, and mounting holes 12 corresponding to the through holes 14 are provided on the clamping arms 3. Mounting bolts for fixing the limiting long plates 4 are provided between the adjacent and corresponding through holes 14 and mounting holes 12.

[0030] Embodiment 3: When carrying out the blanking operation of the finned tubes, if the clamping arms 3 and the limiting long plates 4 are directly opened for the placement of the finned tubes, the finned tubes are likely to be damaged by impact. In order to achieve the buffered blanking operation of the finned tubes, several blanking rods 5 arranged at intervals in the length direction of the limiting long plate 4 and inclined downward towards the other limiting long plate 4 are provided along the lower edge of any one of the limiting long plates 4. When the finned tubes are blanked, they can slowly roll down along the blanking rods 5, thereby reducing their inertia and avoiding the lodging of the fins. In order to further reduce the inertia of the rolling of the finned tubes, a buffer section 6 in a horizontal shape is also provided at the lower end of the blanking rods 5.
