Description

Technical Field

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

[0002] Aluminum flange pipe is composed of aluminum flange and sleeve. The forming of sleeve may involve rolling, welding or extrusion, depending on the shape and size requirements of the sleeve.

[0003] Rolling: For large casing, the rolling process can be used, that is, the aluminum sheet or aluminum strip is rolled into a cylindrical shape, and then welded and sealed to form the basic shape of the casing.

[0004] Extrusion: For certain sleeve shapes and requirements, an extrusion process can be used. During the extrusion process, the aluminum billet undergoes plastic deformation under the action of the extrusion die to form the desired sleeve shape. The extrusion process can precisely control the size and shape of the sleeve, and has high production efficiency.

[0005] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: when the aluminum plate is rolled into an aluminum cylinder and the end gap is welded, it is often first rolled into a cylinder by a rolling device, and then taken to the welding equipment for welding. However, after being removed from the rolling equipment, the aluminum cylinder will have a larger gap at its weld due to stress problems, and it is not convenient for the welding equipment to reduce the weld, which increases the difficulty of welding. Utility Model Content

[0006] 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.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] The cam is provided with a plurality of sliding rails at the top and the bottom of the cam, and the sliding rails are connected with the cam at the top and the bottom of the cam.

[0009] Preferably, the nuts are in contact with the side walls of the side seats that are away from each other.

[0010] Preferably, both ends of the sliding rod passing through the through hole are fixed with limit blocks, and the outer diameter of the limit blocks is respectively larger than the inner diameter of the through hole.

[0011] Preferably, the tooth blocks are respectively inserted into and meshed with tooth plates that match their positions.

[0012] Preferably, both ends of the spring are fixedly connected to one side of the traction plate away from the tooth block.

[0013] Preferably, one end of the extrusion screw passing through the moving mechanism is rotatably connected to a pressing block via a hinge.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up a slide mechanism with a moving mechanism and an extrusion screw, the gap at the weld can be reduced when the flange cylinder is welded by the welding equipment, so that it can achieve the effect of facilitating welding, increasing welding efficiency and increasing welding success rate when being welded.

[0016] 2. The number of moving mechanisms on the slide mechanism can be shifted, increased or decreased, so that the extrusion screw can be adapted to the number of multi-point extrusion clamping according to flange barrels of different lengths, achieving wider applicability.

[0022] 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.

[0023] like Figure 1-4 As shown, a forming device for an aluminum flange sleeve includes a flange cylinder 1, a weld 11 is provided on the top of the flange cylinder 1, a slide mechanism 2 is provided at the position of the weld 11 of the flange cylinder 1, and the slide mechanism 2 includes two side seats 21, and the side walls of the top and bottom ends of the side seats 21 are both drilled with through holes 22, and screws 23 are inserted through the two matching through holes 22 at the bottom ends, and slide rods 25 are inserted through the two matching through holes 22 at the top ends. The screws 23 pass through the through holes 22 and are threadedly connected to nuts 24 at both ends. Long slide rails 27 are fixed to the top and bottom ends of the two side seats 21 close to the flange cylinder 1. The long slide rails 27 at the top are respectively located at the two ends of the outside of the flange cylinder 1, and the two long slide rails 27 at the bottom are respectively located at the two ends of the inside of the flange cylinder 1. Tooth plates 28 are fixed at both ends of the top and bottom of the long slide rails 27. The interior of the long slide rails 27 is slidably connected to the moving mechanism 3, and the interior of the moving mechanism 3 is threadedly connected to the extrusion screw 4. Short slide rails 32 are fixed at both ends of the top and bottom of the moving mechanism 3, and the internal ends of the short slide rails 32 are slidably connected to the traction plates 33. Springs 35 are provided between the short slide rails 32 and the traction plates 33. Two tooth blocks 34 are fixed on the end of the traction plate 33 away from the spring 35.

[0024] Specifically, the nuts 24 are in contact with the side walls of the side seat 21 that are away from each other, and can squeeze the side seat 21 so that the extrusion screw 4 remains clamped stably.

[0025] Specifically, both ends of the slide bar 25 passing through the through hole 22 are fixed with limit blocks 26 , and the outer diameter of the limit blocks 26 is respectively larger than the inner diameter of the through hole 22 to prevent the slide bar 25 from sliding out and play a limiting role.

[0026] Specifically, the tooth blocks 34 are respectively inserted into and meshed with the tooth plates 28 that match the positions, so that the moving mechanism 3 that has moved to a certain position can be limited at that position.

[0027] Specifically, both ends of the spring 35 are fixedly connected to one side of the traction plate 33 away from the tooth block 34 , so that the traction plate 33 can be stably pushed out by the tension.

[0028] Specifically, one end of the extrusion screw 4 passing through the moving mechanism 3 is rotatably connected to the pressing block 5 through a hinge. The pressing block 5 can increase the contact area with the flange tube 1 through movement, making the extrusion of the flange tube 1 more stable.

[0029] The inner threaded slider 31 adjusts the extrusion screw 4 to the position of one end of the weld seam 11 by sliding in the long slide rails 27 , and then the tension of the spring 35 drives the tooth block 34 on one side of the traction plate 33 to pass through and engage with the tooth plate 28 in the matching position, achieving the effect of limiting the moving mechanism 3 and the extrusion screw 4, and the rolling equipment squeezes the two ends of the flange cylinder 1 against each other, so that the weld seam 11 is reduced, and then the extrusion screw 4 is rotated so that the pressure block 5 at its bottom presses against the inner wall / outer wall of the flange cylinder 1 at one end of the weld seam 11, forming a stable clamping state, and the side seat 21 can be squeezed by rotating the nut 24, so that the extrusion screw 4 clamps the end of the flange cylinder 1 more stably. When the limit is stable and the weld seam 11 is reduced, the flange cylinder 1 is taken out from the rolling equipment and taken to the welding equipment, and the weld seam 11 is welded at the position between the long slide rails 27 by the welding equipment.
