[0002] At present, in the process of the roll bending tube machine in the prior art, it is necessary to perform extrusion on the extrusion rollers for multiple times.

However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0055] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0056] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0057] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0058] Figures 1 to 9 An extrusion device according to the present invention is shown, and the extrusion device includes an inner contour support 101 , an extrusion roller assembly 110 and a side extrusion assembly 130 .

[0059] The squeezing roller assembly 110 is used to apply squeezing force to the material strip toward the inner contour support 101. The side squeezing assembly 130 includes a first contour wheel 131 and a first adjustment mechanism 132, wherein the first contour wheel 131 is used to abut against the interface edge of the material strip, and the first adjustment mechanism 132 is connected to the first contour wheel 131, so that the first contour wheel 131 applies squeezing force to the interface edge of the material strip toward the inner contour support 101.

[0060] According to the extrusion device of the present invention, the first adjustment mechanism 132 applies extrusion force to the first profiling wheel 131, so that the first profiling wheel 131 extrude the interface edge of the material strip toward the inner profiling support 101, thereby making it less likely that the edge of the material strip cannot be subsequently welded due to misalignment.

[0061] Reference Figure 1, along the third direction D3, the squeezing roller assembly 110 is spaced apart from the side squeezing assembly 130. The squeezing roller assembly 110 includes two squeezing rollers 111 and a squeezing gap elimination mechanism 120. The two squeezing rollers 111 are arranged along the first direction D1 and are located on both sides of the inner contour support 101. The squeezing gap elimination mechanism 120 is connected to the squeezing rollers 111 and is used to apply a squeezing force to the squeezing rollers 111 toward the inner contour support 101 along the first direction D1, so that the side portions of both sides of the material strip are in contact with the inner contour support 101.

[0062] For details, refer to Figure 1 and Figure 2 When the extrusion device is in use, the material strip extends and is conveyed along the second direction D2, and the cross section of the material strip perpendicular to the second direction D2 is U-shaped. The bending part of the material strip is located at the bottom position between the two extrusion rollers 111, and the two side edges of the material strip are joined under the restriction of the two first profiling wheels 131. Without the extrusion of the first profiling wheels 131, the edges of the material strip will not be aligned and joined, and subsequent welding will not be possible. If the thickness of the material strip is too small, the extrusion of the second profiling wheel 151 along the third direction D3 will also make the material strip fit the inner profiling support 101, so that the two side edges of the material strip are aligned and joined, so that subsequent welding can be completed smoothly.

[0063] Further, see Figure 1 and Figure 2 The extrusion device further comprises a base plate 100, which is fixed relative to the inner contour support 101.

The roller seats 112 are disposed on the substrate 100, and the roller seats 112 are movably disposed relative to the substrate 100 along the first direction D1, so that the squeezing roller 111 is movably disposed relative to the inner contour support 101 along the first direction D1, so that the material strip can be squeezed under the action of the squeezing gap elimination mechanism 120.

[0064] Reference Figure 1 and Figure 4The extrusion device further includes a slide rail 102 and a moving frame 103. The slide rail 102 is fixed to the substrate 100 and extends along the first direction D1. The moving frame 103 is sleeved on the slide rail 102 and is movably arranged relative to the slide rail 102. The moving frame 103 is fixedly connected to the roller seat 112, so that the roller seat 112 is movably arranged relative to the substrate 100 along the first direction D1, so that the extrusion roller 111 can slide stably relative to the inner contour support 101, so that the position of the extrusion roller 111 can be adjusted, so that the material strip can be well fitted to the inner contour support 101, thereby reducing the occurrence of material strip misalignment.

The first adjustment portion 123 can be selected as a bolt or a screw rod, the first adjustment portion 123 is inserted into the connecting frame 122, the fastening nut 124 is sleeved on the first adjustment portion 123 and is threadedly connected to the first adjustment portion 123, and the first adjustment portion 123 can be fixed relative to the connecting frame 122 when the fastening nut 124 is tightened. A blocking piece 125 is provided at the second end of the first elastic member 121, and the first adjusting portion 123 is penetrated through the blocking piece 125 and is threadedly connected with the blocking piece 125, so that the gap between the blocking piece 125 and the connecting frame 122 can be adjusted by rotating the first adjusting portion 123, and finally the elastic force of the first elastic member 121 can be adjusted.
