Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to a hollow aluminum spacer extrusion welding device. Background Art

[0002] The hollow aluminum spacer production line includes a feeding device, a forming unit, a welding unit (including an induction coil and an extrusion roller), a forming unit, a straightening device and a cutting device from front to back. After the aluminum strip is formed by the forming unit, the skin effect and proximity effect of the high-frequency current of the induction coil are used to heat and melt the edge of the tube blank, and pressure welding is performed under the action of the extrusion roller. The formed hollow aluminum spacer is then corrected and shaped by the forming unit, and finally straightened by a straightening machine and cut to a fixed length. However, the current hollow aluminum spacer production line has the following problems: the current production line is affected by the transmission mode, resulting in a processing speed of only 100m / min, resulting in low production efficiency. Therefore, the industry has changed the transmission mode to increase the processing speed, and the processing speed can reach 150m / min-180m / min. At this time, the travel speed of the aluminum spacer is faster, so that the rotation speed of the extrusion roller in the welding unit is also correspondingly faster. However, the current extrusion roller is difficult to meet this high-speed operation requirement, and there are two main factors that affect the rotation speed of the extrusion roller: one is the bearing, and the other is the flow of cooling water inside the extrusion roller. Therefore, this application carries out structural design of the extrusion roller from the above two aspects to increase the rotation speed of the extrusion roller. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0019] like Figure 1 and Figure 2 As shown, the hollow aluminum spacer extrusion welding device includes a mounting base 100, on which two extrusion roller groups 200 and a roller group 300 located below the two extrusion roller groups 200 are symmetrically mounted, an aluminum spacer channel is formed between the two extrusion roller groups 200 and the roller group 300, and a high-frequency induction coil is correspondingly provided on the entrance side of the aluminum spacer channel, and the structures of the left and right extrusion roller groups 200 are basically the same, and only one side is taken as an example for the specific structural description.

[0020] The squeezing roller group 200 includes a bearing seat 201, a vertical roller shaft 202 and a squeezing roller 203. The vertical roller shaft 202 is rotatably mounted in the bearing seat 201 through a bearing. The bearing seat 201 is provided with an oil filling structure for replenishing oil for the bearing. The top end of the vertical roller shaft 202 extends out of the bearing seat 201 and is provided with an upper rotary joint 204. The bottom end of the vertical roller shaft 202 extends out of the bearing seat 201 and is provided with a lower rotary joint 205. The squeezing roller 203 is fixedly mounted on the lower part of the vertical roller shaft 202. The inner circumference of the squeezing roller 203 is provided with an inwardly concave cooling ring cavity 206. The upper inner part of the vertical roller shaft 202 is provided with a cooling water inlet channel 207 that is inclined downward and connects the upper rotary joint 204 with the upper side of the cooling ring cavity 206. The lower inner part of the vertical roller shaft 202 is provided with a cooling water outlet channel 208 that is inclined upward and connects the lower side of the cooling ring cavity 206 with the lower rotary joint 205.

[0021] The utility model provides an oil injection structure in the bearing seat 201 for lubricating and protecting the bearing, thereby meeting the requirement of high-speed rotation of the vertical roller shaft 202 and the squeeze roller 203; at the same time, the present solution designs a cooling water channel in the vertical roller shaft 202, and the cooling water inlet channel 207 and the cooling water outlet channel 208 are respectively connected to the upper part and the lower part of the cooling ring cavity 206. After the cold water enters the cooling ring cavity 206 through the cooling water inlet channel 207, it cools the squeeze roller 203 and is then discharged from the lower part of the cooling ring cavity 206 through the cooling water outlet channel 208. This vertical arrangement can reduce the resistance of water flow movement and reduce the influence of the internal cooling water on the vertical roller shaft 202 during rotation, thereby achieving the purpose of increasing the rotation speed of the vertical roller shaft 202; in addition, the cooling ring cavity 206 is provided on the inner circumference of the squeeze roller 203, which can increase the internal water storage capacity, improve the cooling effect on the squeeze roller 203, and avoid the adhesion of the surface of the squeeze roller 203 and affect the use.

[0022] The high frequency induction coil is a part of the high frequency welding machine, which is a prior art, and its working principle is not described here. The squeezing roller 203 is a ceramic roller, and the high temperature resistance and ultra-high hardness of the ceramic roller fully meet the use requirements in the high frequency induction coil environment.

[0023] See also Figure 3The cooling water inlet channel 207 includes a main water inlet channel 207a arranged along the axis of the vertical roller shaft 202. The top of the main water inlet channel 207a passes through the vertical roller shaft 202. The lower part of the main water inlet channel 207a is connected with a plurality of branch water inlet channels 207b. The branch water inlet channels 207b are connected to the cooling ring cavity 206 by tilting downward from the main water inlet channel 207a. The downward tilting arrangement can reduce the resistance of water flow entering the branch water inlet channels 207b. The cooling water outlet channel 208 includes a main water outlet channel 208a arranged along the axis of the vertical roller shaft 202, the bottom end of the main water outlet channel 208a passes through the vertical roller shaft 202, and the upper part of the main water outlet channel 208a is connected with a plurality of outgoing water channels 208b, and the outgoing water channels 208b are connected to the main water outlet channel 208a by tilting downward from the cooling ring cavity 206. The downward tilted arrangement can reduce the resistance of water flow entering the outgoing water channels 208b.

[0024] See also Figure 3 The inner surface of the cooling ring cavity 206 is an arcuate ring cavity for reducing rotational resistance. The arcuate surface can reduce water flow resistance. When the cooling water enters the arcuate ring cavity from the branch water inlet channel 207b at high speed, it provides inertia force for the water flow to move along the arcuate surface. The cooling water moves rapidly downward along the arcuate surface, and the direction of the water flow changes. The water flow can quickly enter the discharging water channel 208b along the arcuate surface. The branch water inlet channel 207b, the arcuate ring cavity, and the discharging water channel 208b can cooperate to reduce the rotational resistance of the vertical roller shaft 202. At the same time, the cooling water flows quickly, which can meet the good cooling requirements of the extrusion roller 203.

The lubricating oil enters the oil storage chamber 214 through the oil filling hole 217, the oil filling channel 216, and the oil inlet groove hole 215, and is stored and accumulated in the oil storage chamber 214, which can lubricate the upper bearing 210 and the lower bearing 211 at the same time, thereby ensuring that the upper bearing 210 and the lower bearing 211 can operate at high speed and achieve the purpose of reducing the bearing temperature.

[0026] The upper end cover surface is also provided with an auxiliary oil filling hole 218 connected to the upper side of the upper bearing 210, so as to replenish oil to the upper bearing 210 from above and avoid oil shortage in the upper part of the upper bearing 210.
