Description

Technical Field

[0002] Before machining aluminum tube parts, a whole aluminum tube raw material needs to be cut into sections. In order to improve the cutting efficiency of aluminum tubes, multiple aluminum tube raw materials are generally pressed side by side and then cut together. Usually, the structure used for pressing the aluminum tube on the aluminum cutting machine tool is composed of a gantry, a cylinder, a guide rod, a pressure plate and a rubber pad. The cylinder drives the pressure plate and the rubber pad vertically downward to press the aluminum tube. Since multiple aluminum tubes are cut at the same time, the load of the saw blade is large, and the pressure plate presses multiple aluminum tubes at the same time, and the pressure is dispersed. Therefore, the cylinder needs to provide a large pressure to maintain the stability of the aluminum tube during the cutting process. Therefore, although the existing aluminum cutting machine tools do not limit the wall thickness of the aluminum tube, in the actual processing process, when the wall thickness of the aluminum tube is thin, the combined effect of the saw blade cutting force and the pressure plate pressing force has a high probability of causing the aluminum tube to deform after cutting.

[0029] like Figure 4 As shown, the fixed pressure plate 204, the first upper movable pressure plate 205a, the second upper movable pressure plate 205c and the third upper movable pressure plate 205d are all punched with a clearance groove 205f, and the punched clearance groove 205f is made to form a transfer seat 205g, the transfer seat 205g is horizontally arranged, and the transfer seat 205g is hinged with a long connecting rod 211, the long connecting rod 211 includes a first long connecting rod 211a and a second long connecting rod 211b with a length twice that of the first long connecting rod 211a, and the fixed pressure plate 204 and the upper movable pressure plate 205 are hinged.

[0030] like Figure 3 As shown, the lower movable pressure plate 206 connected to the third upper movable pressure plate 205d has hanging walls 206b on both sides bent at right angles in the direction away from the fixed pressure plate 204, and the two ends of the reel 209 are vertically rotatably connected to the hanging walls 206b, the two ends of the reel 209 pass through the hanging walls 206b, and the two end walls of the reel 209 are provided with double offsets 209a, the top of the hanging wall 206b is provided with a slide groove 206c, and the hanging wall 206b is hung with a block 212 through the slide groove 206c, and the two ends of the bottom of the block 212 are provided with U-shaped grooves 212a that match and sleeve the double offsets 209a at the two ends of the reel 209.

[0031] The working principle and advantages of the device are further explained in combination with the prior art: In the prior art, a plurality of aluminum tubes arranged side by side are fixed by pressing down with a flat plate and a rubber pad. Although the aluminum tubes are arranged side by side, the stress characteristics are that the top of the peripheral wall of the aluminum tube is in line contact with the flat plate, and the bottom of the peripheral wall of the aluminum tube is in line contact with the operating table. Under the strong tightening pressure and the cutting force exerted by the saw blade during cutting, the thin-walled aluminum tube is prone to deformation. Although this situation is improved by adding rubber pads in general operating scenarios, the local small amount of elastic deformation of the rubber pads provides very limited protection for the thin-walled aluminum tubes, and still cannot solve the above-mentioned problems.

[0032] Therefore, the present invention provides an aluminum cutting machine 100 having a pressing mechanism 200, such as Figure 2 As shown, the pressing mechanism 200 is to press the pressing belt 208 downward on the upper half of the peripheral wall of the thin-walled aluminum tube through a fixed pressing plate 204 and a plurality of lower movable pressing plates 206, thereby achieving the purpose of fixing the thin-walled aluminum tube. Figure 1 and Figure 2 As shown, after the thin-walled aluminum tube is pressed and fixed on the table of the aluminum cutting machine 100, the force direction of the thin-walled aluminum tube becomes: the entire upper half of the peripheral wall of the aluminum tube is evenly stressed through the sleeve pressure belt 208, the two sides of the peripheral wall of the aluminum tube are supported by the fixed pressure plate 204 and the lower dynamic pressure plate 206, and the bottom of the aluminum tube is supported by the table of the aluminum cutting machine 100. The force points on the peripheral wall of the aluminum tube are increased and evenly distributed, and the contact area between the peripheral wall of the aluminum tube and the pressure object is significantly increased compared with the original use of rubber pads. This allows the thin-walled aluminum tube to withstand higher tightening pressure, obtain greater friction, and safely withstand the cutting force of the saw blade.

[0033] To achieve the above-mentioned target functions, the device also involves the following technical details: First, when the device is pressing and fixing aluminum tubes of different numbers and diameters, it is necessary to adjust the different working lengths of the pressing belt 208 so that the bottom ends of the fixed pressing plate 204 and the lower movable pressing plate 206 are in proper positions after the aluminum tubes are pressed and fixed. Obviously, if the pressing belt 208 is too long, the bottom ends of the fixed pressing plate 204 and the lower movable pressing plate 206 will contact the table of the aluminum cutting machine 100, so that the pressing belt 208 cannot be tightened, resulting in failure of pressing and fixing. If the pressing belt 208 is too short, the pressing belt 208 does not have enough length to cover the upper half of the peripheral wall of the aluminum tube, reducing the contact area between the pressing and fixing mechanism 200 and the aluminum tube, and also causing the side of the aluminum tube to no longer be effectively supported laterally. Therefore, one end of the pressing belt 208 of the device is fixed to the bottom of the fixed pressure plate 204, and the other end is wound around the reel 209. The working length of the pressing belt 208 is adjusted by winding or releasing the reel 209. The two ends of the reel 209 are rotatably assembled with the hanging walls 206b on both sides of the lower movable pressure plate 206. Figure 2 and Figure 3As shown, by hanging the block 212 on the hanging wall 206b, the block 212 can only slide up and down along the slide groove 206c of the hanging wall 206b. Therefore, when the U-shaped groove 212a of the block 212 is sleeved with the double offsets 209a at both ends of the reel 209, the reel 209 can be prevented from rotating, thereby locking the working length of the pressing belt 208. Secondly, when the device is used to press aluminum tubes of different diameters, it is necessary to quickly adjust the distance between the fixed pressure plate 204 and the lower movable pressure plate 206 and the distance between adjacent lower movable pressure plates 206, such as Figure 2 and Figure 4 As shown, the device pulls the third upper movable platen 205d along the axial direction of the guide rod 203 through the handle 213, and pulls the first long connecting rod 211a through the adapter 205g of the third upper movable platen 205d. During the process, the angle between the first long connecting rod 211a and the second long connecting rod 211b changes synchronously, so that the distance between the fixed platen 204 and the lower movable platen 206 and the distance between adjacent lower movable platens 206 change synchronously; The device provides two quick positioning operation modes based on the above adjustment function. The first operation mode is as follows: Figure 1 and Figure 4 As shown, first pull the handle 213 significantly, place a calibration object with the same size as the outer diameter of the aluminum tube to be cut (or slightly smaller) between the short side 204a of the fixed pressure plate 204 and the adjacent retaining edge 205b, push the handle 213 back, so that the short side 204a and the retaining edge 205b clamp the calibration object. At this time, the distance between the fixed pressure plate 204 and the lower movable pressure plate 206 and the distance between the adjacent lower movable pressure plates 206 will be equal to or slightly smaller than the diameter of the aluminum tube to be cut. The second operation method is, refer to Figure 2 The guide rod 203 can be provided with a scale mark at one end of the handle 213. The scale mark marks the distance between adjacent lower movable plates 206, which corresponds to the diameter of the aluminum tube to be cut. If the auxiliary scale mark is used, no calibration object is required. Thirdly, in consideration of the fact that there are errors in the dimensions of the components of the pressing mechanism 200, errors in the structural assembly, errors in the dimensions of the selected calibration objects, and errors in the diameters of the aluminum tubes to be cut (for example, among the aluminum tubes to be processed, there are errors in the diameters of one or more of the aluminum tubes and the other aluminum tubes), the parallelogram structure connected by the short connecting rod 207 allows the lower movable platen 206 to maintain a parallel posture with the upper movable platen 205, and at the same time, it can float relative to the upper movable platen 205 along the axial direction of the guide rod 203. For example, during the pressing process, the lower movable platen 206 cannot be exactly It is not inserted between two adjacent aluminum tubes, but first contacts the peripheral wall of the aluminum tube. Then, within the floating range allowed by the parallelogram, the downward pressure will make the lower movable pressure plate 206 slide along the peripheral wall of the aluminum tube until it is inserted between the adjacent aluminum tubes, wherein the tension spring acts to allow the lower movable pressure plate 206 and the pressure belt 208 to be close to the outer wall of the aluminum tube. The purpose of using an inclined upward design for the connecting ear 206a at a high position of the lower movable pressure plate 206 is to avoid structural interference between the connecting ear 206a and the long connecting rod 211 during the adaptive adjustment process of the lower movable pressure plate 206, thereby increasing the movable range of the lower movable pressure plate 206.

[0034] In summary, the device increases and balances the stress points and directions of the peripheral wall of the thin-walled aluminum tube by inserting pressure plates into both sides of the thin-walled aluminum tube so that the pressure belt 208 is sleeved on the aluminum tube, so that the contact area of ​​the peripheral wall of the thin-walled aluminum tube under pressure is significantly increased compared with the original rubber pad, thereby improving the upper limit of the tightening pressure that the thin-walled aluminum tube can withstand, and making the thin-walled aluminum tube stable and not easy to deform during cutting.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
