Description

Technical Field

[0001] The invention belongs to the technical field of composite tube blank production equipment, and in particular relates to a bimetallic composite tube blank production equipment. Background Art

[0002] Composite tube blanks are the raw materials for producing composite tubes, so the production of tube blanks is particularly important. Composite tube blanks are composed of an outer hollow material and an inner solid material. The outer hollow material and the inner solid material are formed by a melting and casting method. The main method is to put an arc-starting plate and an electroslag material in the outer hollow material. The outer hollow material and the inner solid material need to be connected to electricity separately, that is, the inner solid material (electrode) is melted and combined with the outer hollow material to form a composite tube blank by electroslag remelting.

[0003] When in use, the outer layer hollow material is placed on the rotating support device, which supports the outer layer hollow material and drives it to rotate; the inner layer solid material is clamped by the electrode clamping device and can be driven to rotate; the outer layer hollow material is heated by the heating device.

[0004] Common electroslag remelting equipment, such as: a vacuum / gas shielded electroslag remelting continuous directional solidification device disclosed in patent application No. 201010614036.0; patent application No. 201510888712.6 discloses a high-speed, low-inclusion electroslag remelting device and a remelting method thereof, the transformer is connected to the water tank (outer hollow material) and the electrode (inner solid material) respectively, the inner solid material is in a rotating state, and the water tank is in a fixed state. However, in order to improve the bonding effect, when producing composite tube blanks, the outer hollow material needs to be rotated, that is, the outer hollow material is placed on a rotating support device, and the outer hollow material is driven to rotate by the rotating device. However, since the outer hollow material also needs to be connected to electricity, additional conductive equipment needs to be set up for conduction, which inevitably increases the complexity of the equipment, and the conductive effect is not ideal. At the same time, the electrode needs to be rotated and connected to electricity while clamping, so a combination of multiple devices is required to achieve it, resulting in a more complex overall structure in the prior art.

[0005] During the production process, the outer hollow material needs to be heated, usually by putting the coil (heating ring) of the heater (induction furnace / medium frequency induction furnace) on the outer hollow material. Therefore, the position of the heating ring needs to be adjusted according to the position of the outer hollow material to ensure that the two are in a coaxial relationship as much as possible, but the position adjustment in the existing technology is relatively cumbersome.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A movable frame 108 is hinged on the roller frame 1013, and a telescopic push rod 109 is provided between the movable frame 108 and the roller frame 1013. A pressure roller 1010 is rotatably connected to the movable frame 108, and the movable frame 108 is rotated and opened and closed by the extension and retraction of the telescopic push rod 109, so that the pressure roller 1010 cooperates with the two clamping rollers 106 to clamp the electrode 1011; the brush assembly 104 is arranged on the cross arm 102 or the roller frame 1013, and the electrode 1011 is electrically connected by being connected to the brush assembly 104 after being clamped. The telescopic push rod 109 can adopt an electric cylinder in the prior art, the cylinder body of the electric cylinder is hinged on the roller frame 1013, and the rod body (piston rod) of the electric cylinder is hinged to the moving frame 108.

[0087] When in use, the telescopic push rod 109 is retracted to open the mobile frame 108, and the pressure roller 1010 is away from the two clamping rollers 106. After the electrode 1011 is moved between the two clamping rollers 106 and the pressure roller 1010, the telescopic push rod 109 is extended to make the mobile frame 108 move in the opposite direction and close, so that the pressure roller 1010 and the two clamping rollers 106 clamp the electrode 1011, and the clamping and fixing of the electrode 1011 is completed.

A telescopic rod 206 is provided between the telescopic arm 203 and the sleeve 204. Both ends of the telescopic rod 206 are respectively hinged to the telescopic arm 203 and the sleeve 204, and the telescopic arm 203 is driven to rotate by the rotation of the telescopic rod 206. The telescopic rod 206 can adopt an electric telescopic cylinder in the prior art.

[0090] When in use, the position of the heater 202 is adjusted by adjusting the extension length of the telescopic arm 203 and adjusting the angle through the telescopic rod 206 to ensure that the heating ring 2020 of the heater 202 is coaxial with the outer hollow material 2013. When the sliding sleeve 204 moves, the heater 202 can also move accordingly, that is, the heating ring 2020 moves axially along the outer hollow material 2013.

[0091] like Figures 16 to 23 As shown, the rotating support device 3 includes a frame 301 and a moving mechanism 302. The moving mechanism 302 is arranged at the bottom of the frame 301. The frame 301 is driven to move by the moving mechanism 302. The moving mechanism 302 can adopt mechanisms such as track wheels and connecting rod drives in the prior art. No matter what mechanism is adopted, as long as it can realize the movement of the frame 301, it can be used.

The elastic component 10402 is used to ensure that the brush 10400 is in elastic contact with the electrode 1011 and to ensure that the brush 10400 is always in contact with the electrode 1011. The main purpose of the moving mechanism 1012 is to realize the movement of the connecting plate 10401, so it can adopt a linear moving mechanism in the prior art, such as: a linear motor, a telescopic electric cylinder, a screw lift, etc. Take the telescopic electric cylinder (with guide) as an example: the cylinder body of the telescopic electric cylinder is fixed on the cross arm 102 or the roller frame 1013, the telescopic rod (piston rod) of the telescopic electric cylinder is connected to the connecting plate 10401, and the movement of the connecting plate 10401 is realized by the extension and retraction of the telescopic rod.

[0107] Further, the elastic component 10402 includes a spring 104020 and a connecting bolt 104021.

Through the above-mentioned structural setting, the outer hollow material needs to pass through the protective sleeve 208, and the protective sleeve 208 can prevent the outer hollow material from directly contacting the heating ring 2020, thereby avoiding collision due to shaking.
