Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a forming device for an aluminum flange sleeve. Background Art

[0002] Aluminum flange sleeves are made of pipe fittings and flanges. There are two traditional forming methods, as detailed below:

[0003] Die-casting: Die-casting is a metal casting process characterized by applying high pressure to the molten metal in the mold cavity, so that it quickly fills the mold cavity and solidifies into shape. Die-casting is to die-cast the flange and sleeve as a whole to form an integrated structure.

[0004] Advantages: The die-cast one-piece aluminum flange sleeve has a compact structure and high connection strength. By reducing subsequent processes such as welding, it may help improve production efficiency and reduce production costs. In addition, the one-piece structure also helps improve sealing performance and service life;

[0005] Applicable scenarios: This molding method is suitable for occasions with high requirements on connection strength, sealing and production efficiency.

[0006] Welding: Welding is a process that uses heat, pressure, or both to achieve atomic bonding between two or more separate metal materials to form a permanent connection. In welding, the flange and sleeve are separately processed parts that are connected together through welding.

[0007] Advantages: The welding forming method is highly flexible and can select the appropriate flange and sleeve size, material, etc. according to needs. At the same time, welding technology is mature and widely used, and is suitable for various complex connection structures;

[0008] Applicable scenarios: When the pipes or equipment to be connected have large differences in size, material, etc., or when there are special requirements for the connection structure, welding may be more appropriate.

[0009] In the process of implementing the welding connection solution, the inventors discovered that the following problems in the prior art have not been well solved: the traditional welding method is to place the pipe fitting on the flange, and then the worker holds the welding gun to fully weld the contact area between the two. To maintain the stability of the welding, a clamp is required to place the flange. The clamp is used to clamp the flange during welding to prevent the workpiece from shaking due to various factors during welding;

[0010] In order to make the sleeve contact more stably, another clamp needs to be added to the sleeve. After the sleeve and the flange are fitted, the two clamps clamp the two parts respectively to achieve a stable effect during welding. Although this method can achieve a stable effect during welding, the operation is more cumbersome and involves more steps, which is not very practical. Utility Model Content

[0011] The main purpose of the utility model is to provide a forming device for an aluminum flange sleeve, which can effectively solve the problems in the background technology.

[0012] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0013] A forming device for an aluminum flange sleeve comprises a support platform, a placing platform is provided on the top of the support platform, a plurality of brackets are fixed on the position of the support platform outside the placing platform, a fixing cylinder is fixed on the top between the brackets, a bearing 1 is installed inside the fixing cylinder, an internal threaded tube is provided inside the bearing 1, a long screw is inserted through the inside of the internal threaded tube, the inner wall of the internal threaded tube is threadedly connected to the outer wall of the long screw, the bottom outer wall of the long screw is sleeved with an internal threaded tube, a plurality of pressure plates are fixed on the bottom end of the outer wall of the internal threaded tube, the outer wall of the long screw is threadedly connected to the inner wall of the internal threaded tube, a driving motor is fixed on the bottom of the support platform, and a driving shaft is fixed on the output end of the driving motor.

[0014] Preferably, one end of the driving shaft away from the driving motor is fixedly connected to the bottom of the placement table.

[0015] Preferably, the support platform is provided with a second bearing at the position of the driving shaft, and the driving shaft is rotatably connected to the second bearing after passing through it.

[0016] Preferably, the internally threaded tube is rotatably connected to the fixed cylinder via a bearing 1.

[0017] Preferably, a plurality of handles are fixed to the top end of the outer wall of the internally threaded barrel, the top end of the outer wall of the internally threaded tube, and the top end of the outer wall of the long screw.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The flange is placed on the placement table, and the sleeve is placed on the flange. At this time, the rotation of the internal threaded barrel can descend on the long screw, so that the bottom of the pressure plate can touch the top of the sleeve and form a downward pressure state. This pressure can press the sleeve tightly against the top of the flange. Not only does the downward pressure make the two have better fitting stability during the welding process, but at the same time, only the adjustment of the internal threaded barrel is required, which reduces the operating steps of this device. It can play a quick limiting effect after the work is placed in place, and the operation is simple and fast.

[0020] 2. The long screw of this device is threadedly connected to the internal threaded pipe. When the height of the casing is low, hold the internal threaded pipe to keep it still. After turning the long screw, the horizontal height of the bottom of the long screw can be lowered, so that the internal threaded tube used for downward pressure limit will also be lowered, so that the pressure plate can contact the lower top of the casing. On the contrary, when the height of the casing is high, the height of the pressure plate can also be increased by turning the long screw, so that the scope of use of this device is increased.

[0021] 3. After the drive motor starts working, it drives the placement table to rotate through the drive shaft, so that the flange and sleeve rotate together. As a result, when welding, the worker does not need to walk around in circles. The rotating workpiece can be welded at the same position, ensuring welding accuracy.

[0022] Since the pressure plate presses down on the sleeve, when the flange and the sleeve rotate, the internal threaded tube is connected to the rotation of the fixed cylinder through the bearing 1, so that the pressure plate can follow the rotation and ensure the limit stability during rotation.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figure 1-5 As shown, a forming device for an aluminum flange sleeve includes a support platform 1, a placing platform 2 is provided on the top of the support platform 1, a plurality of brackets 5 are fixed on the position of the support platform 1 outside the placing platform 2, a fixing cylinder 6 is fixed on the top between the brackets 5, a bearing 7 is installed inside the fixing cylinder 6, an internal threaded tube 8 is provided inside the bearing 7, a long screw 9 is inserted through the inside of the internal threaded tube 8, the inner wall of the internal threaded tube 8 is threadedly connected to the outer wall of the long screw 9, the bottom outer wall of the long screw 9 is sleeved with an internal threaded tube 10, a plurality of pressing plates 11 are fixed to the bottom end of the outer wall of the internal threaded tube 10, the outer wall of the long screw 9 is threadedly connected to the inner wall of the internal threaded tube 10, a driving motor 3 is fixed to the bottom of the support platform 1, and a driving shaft 4 is fixed to the output end of the driving motor 3.

[0031] Specifically, the end of the drive shaft 4 away from the drive motor 3 is fixedly connected to the bottom of the placement table 2, and the support table 1 is installed with a bearing 2 13 at the position of the drive shaft 4. The drive shaft 4 and the bearing 2 13 are penetrated and rotated to connect, so that the drive shaft 4 drives the rotation of the placement table 2 more stably.

[0032] Specifically, the internal threaded tube 8 is rotatably connected to the fixed tube 6 through a bearing 7, and can perform auxiliary rotation when the placement table 2 rotates.

[0033] Specifically, a plurality of handles 12 are fixed to the top of the outer wall of the internally threaded barrel 10, the top of the outer wall of the internally threaded tube 8 and the top of the outer wall of the long screw 9, so as to facilitate the rotation of the respective components when making adjustments.

[0034] Working principle: the flange is placed on the placement table 2, and the sleeve is placed on the flange. At this time, the rotation of the internal threaded tube 10 can descend on the long screw 9, so that the bottom of the pressure plate 11 can touch the top of the sleeve and form a downward pressure state. The pressure can press the sleeve tightly against the top of the flange. Not only does the downward pressure make the two have better fitting stability during the welding process, but at the same time, only the adjustment of the internal threaded tube 10 is required, which reduces the operating steps of the device and can play a quick limiting effect after the work is put in place. The operation is simple and fast; the long screw 9 of the device is threadedly connected with the internal threaded tube 8. When the height of the sleeve is low, hold the internal threaded tube 8 to keep it still. After rotating the long screw 9, the horizontal height of the bottom of the long screw 9 can be lowered. The internal threaded tube 10 used for downward pressure limiting will also descend, so that the pressure plate 11 can contact the lower top of the sleeve. On the contrary, when the height of the sleeve is high, the height of the pressure plate 11 can be increased by rotating the long screw 9, thereby increasing the scope of use of the device; after the driving motor 3 works, it drives the placement table 2 to rotate through the driving shaft 4, so that the flange and sleeve rotate together, so that when welding, the staff does not need to walk around in circles, and can weld the rotating workpiece at the same position, ensuring the accuracy of welding; because the pressure plate 11 has a downward pressure on the sleeve, when the flange and sleeve rotate, the internal threaded tube 8 is connected to the rotation of the fixed tube 6 through the bearing 1 7, so that the pressure plate 11 can follow the rotation, ensuring the limit stability during rotation.
