Description

Technical Field

[0001] This utility model relates to the field of aluminum processing equipment technology, and in particular to a chip suction pipe and an aluminum surface milling device using the same. Background Technology

[0002] Milling is a machining method that uses a milling cutter as a cutting tool to machine the surface of an object. Milling refers to cutting a workpiece with a rotating multi-edged cutting tool, and it is a highly efficient machining method. During operation, the cutting tool rotates while the workpiece moves; the workpiece can also be stationary, but the rotating cutting tool must still move.

[0003] For large-area aluminum milling, a large cutter head (up to 2.2 meters in diameter) with multiple cutting edges (24 cutters, 22 roughing cutters, and 2 finishing cutters) is required for simultaneous single-cutting, enabling mirror milling. To prevent aluminum chips from flying everywhere during aluminum production, a chip suction hood is usually installed outside the cutter head and connected to a negative pressure chip removal pipe for chip removal. For example, CN215880951U discloses a chip removal hood for a cutting chip removal device used in aluminum production, specifically including inclined, vertical, and horizontal sections. In the actual aluminum milling process, the cutter head used is a floating and adjustable structure to adapt to the different thicknesses of aluminum plates. Therefore, if the chip suction pipe cannot adapt to the floating of the cutter head, it cannot meet the processing requirements of aluminum plates of different thicknesses.

[0004] In summary, to meet the adaptation requirements of floating cutterheads, it is necessary to design a chip suction pipe that can float within a certain small range. Utility Model Content

[0011] In an optional embodiment of this utility model, the elbow pipe is integrally provided with a flange for detachable connection with the reducing cover pipe, and the reducing cover pipe is provided with a connecting plate suitable for mating with the flange.

[0012] In an optional embodiment of this utility model, the connecting disc and the connector are designed as a variable diameter pipe with a gradually changing inner diameter, and the inner diameter of the end of the variable diameter pipe connected to the connecting disc is smaller than the inner diameter of the end of the variable diameter pipe connected to the connector.

Detailed Implementation

[0020] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] Example 1: Please see Figures 1 to 5 As shown, this embodiment provides a dust collection pipe, which includes at least: a joint pipe 1, a reducing shroud 2 rotatably fitted to one end of the joint pipe 1, and an elbow pipe 3 connected to the end of the reducing shroud 2 facing away from the joint pipe 1. The end of the reducing shroud 2 facing away from the elbow pipe 3 has a connector 21 suitable for partial insertion into the joint pipe 1; the joint pipe 1 has a connecting head 11 suitable for insertion into the connector 21 and rotatably fitted with the connector 21.

[0022] The rotational fit between the joint pipe 1 and the deformable cover pipe is achieved through the following structure: First, in terms of shape, the connector 11 has at least a pair of oppositely distributed arc-shaped sides 111, and the connector 2 has an arc-shaped inner wall formed to fit the arc-shaped sidewalls 111. For the connector 1, it may also include a pair of flat sidewalls 112, which are orthogonally distributed with the pair of arc-shaped sidewalls 111 to form the connector 11. In the connector 21, a pair of flat inner walls are designed corresponding to the pair of flat sidewalls 112. This shape design allows the connector 11 to rotate within the connector 21. Second, the connector 21 has a pair of symmetrically distributed connecting grooves 22 on the sidewalls corresponding to the pair of flat inner walls; and connecting shafts 12, suitable for rotating with the pair of connecting grooves 22, are distributed on the pair of flat sidewalls of the connector 11. The axis of symmetry of the pair of connecting shafts 12 here can be understood as a straight line passing through the center of the joint pipe 1 in the depth direction and through the center point of the pair of arc-shaped sidewalls of the connector 11. Based on this, the connector 11 can rotate in the connector 21 with the cooperation of the pair of connecting shafts 12 and the corresponding connecting grooves 22.

[0023] More specifically, each connecting groove 22 is U-shaped, and the opening of each connecting groove 22 extends to the end of the connector 21 facing away from the elbow pipe 3. Each connecting shaft 12 is adapted to be inserted into the connecting groove 22 from the opening of the connecting groove 22. Furthermore, a pair of fixing pieces 4 are provided on the outer wall of the connector 21 to mate with each pair of connecting grooves 22. These fixing pieces 4 can be connected to the outer wall of the connector 21 by means of, but not limited to, screws. Each fixing piece 4 is adapted to be fixed to the connector 21 along a direction perpendicular to the groove depth of the connecting groove 22 to prevent the connecting shaft 12 from sliding from the connecting groove 22 towards the opening of the connecting groove 22.

[0024] The following is an example of an optional implementation, illustrated in the accompanying drawings. A flange 51 is integrally provided on the elbow pipe 3 for detachable connection with the reducing sleeve 2, and the reducing sleeve 2 is provided with a connecting plate 52 suitable for mating with the flange 51. Here, the flange 51 and the connecting plate 52 can be connected, for example, but not limited to, with screws. Furthermore, the connection plate 52 and the connector 21 are designed as a reducing pipe body with a gradually changing inner diameter, and the inner diameter of the end of the reducing pipe body connected to the connecting plate 52 is smaller than the inner diameter of the end of the reducing pipe body connected to the connector 21. This design of the reducing pipe body simultaneously meets the dimensional requirements of both the connecting plate 52 and the connector 21.

[0025] Next, it should be noted that, in order to facilitate the connection between the chip suction pipe and the aluminum surface milling device in this embodiment, the end of the joint pipe 1 away from the reducing cover pipe 2 is also rotatably fitted with a connector pipe 6. The connector pipe 6 is used to connect with the aluminum surface milling device, serving as a transition connection between the aluminum surface milling device and the chip suction pipe.

[0026] Based on the above structure, and referring to the accompanying drawings, an example is given of the following: the mating structure between the connector pipe 6 and the joint pipe 1 in this embodiment is as follows: The connector tube 6 is formed by splicing together a pair of oppositely distributed rectangular plates 61 and a pair of oppositely distributed isosceles trapezoidal plates 62. The articulated conduit 1 has a rectangular cavity suitable for partial insertion of the connector tube 6. One pair of opposing inner walls of this rectangular cavity is adapted to fit against the pair of isosceles trapezoidal plates 62 of the connector tube 6, and the other pair of opposing inner walls of the rectangular cavity is adapted to have a gap between them and the pair of rectangular plates 61 of the connector tube 6. This gap is designed to provide room for rotation of the articulated conduit 1 relative to the connector tube 6. It should be noted that the sidewall of the articulated conduit 1 that fits against the pair of isosceles trapezoidal plates 62 is on the same side of the articulated conduit 1.

[0027] Based on the above structure, when the joint tube 6 and the joint pipe 1 rotate and cooperate, the joint tube 6 needs to move within a certain range in the vertical direction. The entire joint pipe 1 can rotate relative to the joint tube 6, so that the end of the joint pipe 1 connected to the joint tube 6 can move upward with the joint tube 6. At the same time, the end of the joint pipe 1 connected to the connector 11 can move downward relative to the connector 21. This allows the entire joint pipe 1 to adapt to the upward movement of the joint tube 6.

[0028] Furthermore, it should be noted that outer baffles are respectively provided between the outer wall of the joint pipe 1 and the outer walls of the pair of rectangular plates 61 of the connector pipe 6. For each pair of outer baffles, they are fixedly connected to the joint pipe 1. Each outer baffle includes a root 71 connected to the joint pipe 1 and a fin 73 extending from the joint pipe 1 toward the connector pipe 6. The root 71 is V-shaped, and the V-shaped opening of the root 71 faces the root 71. The fin 73 is a roughly flat structure that abuts against the outer wall of the connector pipe 6. An arc-shaped connection 72 is formed between the fin 73 and the root. In order to prevent the arc-shaped connection from interfering with the rotation of the joint pipe 1 relative to the connector pipe 6, a slanted notch 63 is formed at the corner between the pair of side walls of the pair of isosceles trapezoidal plates 62 and the pair of side walls of the pair of rectangular plates 61 at the end where the joint pipe 1 is connected to the connector pipe 6. Specifically, the slanted notch 63 is designed on the pair of side walls of the pair of isosceles trapezoidal plates 62 of the joint pipe 1.

[0029] In summary, for the chip suction pipe of this embodiment, the rotational cooperation between the joint pipe 1 and the variable diameter cover pipe 2 allows the chip suction pipe to rotate relative to the variable diameter cover pipe 2 according to the processing requirements of the aluminum flat milling device. This allows the joint pipe 1 to float in a small range in the vertical direction, thereby improving the overall flexibility of the chip suction pipe during use.

[0030] Example 2: Based on the chip suction pipe of Example 1, this embodiment provides an aluminum flat milling device, which includes at least the chip suction pipe of Example 1.

[0031] Specifically, the connector pipe 6 of the chip suction pipe is connected to the suction hood installed in the aluminum surface milling device. Then, the connector 11 of the joint pipe 1 is inserted into the reducing hood pipe 2, and the joint pipe 1 and the reducing hood pipe 2 are connected by the cooperation of the connecting shaft 12 and the connecting groove 22. Then, one end of the joint pipe 1 is inserted into the connector pipe 6, and the elbow pipe 3 is connected to the factory's chip suction pipeline. In this way, the assembly and connection of the entire chip suction pipeline with the factory's chip suction pipeline and the aluminum surface milling device is completed.
