Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate chamfering devices, and in particular to an aluminum plate chamfering device. Background Art

[0002] Aluminum plate refers to a building decoration material that is processed by chroming and other treatments and then fluorocarbon spraying technology. In the actual production process, the raw materials need to be cut and processed. However, burrs and flanging often occur on the edges of the aluminum plate after cutting. These burrs and flanging not only affect the precise positioning and fastening between the workpiece and the workpiece, resulting in reduced installation accuracy, but also during the assembly process, the burrs can easily scratch the surface of adjacent workpieces or cause harm to the installer's body. Therefore, chamfering is required after the aluminum plate is cut to remove the burrs caused by machining and make its edges no longer sharp.

[0003] Existing chamfering processing equipment is generally divided into handheld or fixed types. When workers chamfer the plates with handheld equipment, the chamfer is easily skewed due to the movement of the plates, which affects the chamfering quality. In addition, the long-term rotation of the aluminum plate for chamfering makes the workers' hand muscles tired, the labor intensity is high, and the work efficiency is low. When the fixed equipment is in use, the aluminum plate is generally clamped and fixed by a clamping mechanism, and then the chamfering drill bit is controlled to chamfer along the edge of the aluminum plate in turn. After chamfering one side, the aluminum plate needs to be turned over and the other side needs to be chamfered. The operation is more troublesome and the work efficiency is low.

At the same time, the bottom of the first mounting plate 25 is fixedly connected to the second mounting plate 26 by a first bolt 252, and the top of the second mounting plate 26 is provided with an embedding groove 261, so the first mounting plate 25 can be embedded and fixed on the top of the second mounting plate 26 to increase the installation stability.

[0054] like Figure 1 , Figure 4 and Figure 5 As shown, in the present embodiment, further, the clamping head 27 is hollow and has an annular opening on the top. The inner bottom surface of the clamping head 27 is fixedly connected to the bottom of the second mounting plate 26 through a spring 271. The spring 271 is evenly distributed on the inner bottom surface of the clamping head 27 to provide a uniform buffering effect to prevent the clamping head 27 from exerting excessive pressure on the aluminum plate to be processed and causing rigid damage.

The diameter of the sliding ring 262 is larger than the inner edge of the annular opening on the top of the clamping head 27, and the sliding ring 262 is separated from the inner wall of the clamping head 27 so that the sliding ring 262 can be slid up and down in the clamping head 27 without falling out.

[0055] like Figure 1 and Figure 6-8As shown, in the present embodiment, the chamfering device further comprises a chamfering mechanism, which comprises a concave plate 44, wherein the concave plate 44 lies on its side and the notch of the concave plate 44 faces away from the side plate 17, and at the same time, a second hydraulic cylinder 42 is fixedly connected to the back side of the side plate 17, and the second hydraulic cylinder 42 passes through the side plate 17 and is provided with a second telescopic rod 421 which is telescopically arranged inwardly, and the second telescopic rod 421 is fixedly connected to the side surface of the concave plate 44, so that the second hydraulic cylinder 42 can drive the concave plate 44 to slide in the openings 111 of the two support plates 11, and limit strips 112 which are in the same direction as the sliding direction are arranged on the upper and lower sides of the opening 111, and small slide grooves 441 which are in the same direction as the sliding direction are arranged on the top and bottom surfaces of both sides of the concave plate 44, and the limit strips 112 can be embedded in the small slide grooves 441 so that the concave plate 44 can slide stably.

[0056] like Figure 1 and Figure 6-8 As shown, in this embodiment, further, a pair of sliding grooves 442 penetrating the plate surface are provided on both sides of the concave plate 44, and a pair of sliding seats 45 are respectively provided in the two sliding grooves 442 for sliding up and down movement, the middle part of the sliding seat 45 is smaller in cross section than the two ends, and the middle part of the sliding seat 45 is separated from the groove wall of the sliding groove 442, so that the sliding seat 45 can be embedded in the sliding groove 442, increasing the stability of sliding. A chamfering roller 4 is rotatably provided between the two sliding seats 45, and in this embodiment, the chamfering roller 4 is preferably a wire roller, because the hardness of steel is much higher than that of aluminum, the wear resistance of steel is significantly better than that of aluminum, and the wire roller can effectively chamfer the burrs on the edge of the aluminum plate.

[0057] like Figure 1 and Figure 6-8 As shown, in the present embodiment, further, the chamfering roller 4 is fixedly provided with a second driving source on the sliding seat 45 on one side. In the present embodiment, the second driving source comprises a first motor 41, and the output end of the first motor 41 is fixedly connected to the chamfering roller 4 for driving the chamfering roller 4 to rotate; at the same time, the chamfering roller 4 is fixedly connected with a third driving source on the concave plate 44 away from the first motor 41, and the third driving source comprises a second motor 43, and the output end of the second motor 43 is fixedly connected with a screw rod 46, and the screw rod 46 is rotationally engaged with the sliding seat 45 for driving the chamfering roller 4 to move up and down, and the other end of the screw rod 46 is rotationally connected with a fixed block 461, and the fixed block 461 is fixedly connected to the concave plate 44, and a clearance opening 113 is also provided on the support plate 11 so that the second motor 43 can move freely with the concave plate 44.

[0058] The technical principle of the present invention is: when it is necessary to chamfer the aluminum plate, first place the center of the aluminum plate to be processed on the rotating disk 31, start the first hydraulic cylinder 21 to control the clamping head 27 to extend and retract downward to clamp the aluminum plate, then start the first motor 41 to drive the chamfering roller 4 to rotate, start the second hydraulic cylinder 42 to control the chamfering roller 4 to approach the aluminum plate to chamfer the burrs on the edge of the aluminum plate, and after chamfering is completed, start the second motor 43 to drive the chamfering roller 4 to move up or down to chamfer the opposite sides of the aluminum plate. After chamfering one side, control the chamfering roller 4 to retreat, and then start the stepper motor 23 to drive the aluminum plate to rotate 90°, and repeat the above steps to efficiently complete the chamfering of the four edges of the aluminum plate.

[0059] The embodiment of the present invention presses the center of the aluminum plate through the clamping head 27, so that the aluminum plate can be stably fixed, avoiding the movement of the aluminum plate during the chamfering process and ensuring the quality of the chamfering processing. The springs 271 evenly distributed in the clamping head 27 can provide a uniform buffering effect to avoid excessive pressure of the clamping head 27 on the aluminum plate to be processed, causing rigid damage; the clamping head 27 is then driven to rotate by the stepping motor 23, so the rotation angle can be accurately controlled, and the direction of the side of the aluminum plate that needs to be chamfered can be controlled, so as to quickly and accurately chamfer all sides of the aluminum plate; at the same time, by setting the first motor 41 to drive the chamfering roller 4 to rotate, the burr edge of the aluminum plate can be quickly polished and chamfered, and by driving the second hydraulic cylinder 42 and the second motor 43 to control the upper and lower positions of the chamfering roller 4, the chamfering roller 4 can be quickly and accurately moved to the chamfered position, greatly improving the processing efficiency.

[0060] like Figure 1-3 and Fig. 9As shown, according to another embodiment of the present invention, further, the bottom of the rotating disk 31 is also sealed and fixedly connected to a rotating ring 3 by a second bolt 311, and the rotating ring 3 is rotatably set in the mounting groove 16. A fixing groove 34 that fits with the ring shape of the rotating ring 3 is provided on the top of the rotating ring 3 so that the rotating ring 3 can be embedded and sealed and fixed, and a limiting edge 35 is fixedly provided on the outer side of the rotating ring 3, and an annular groove 161 is arranged around the mounting groove 16. The limiting edge 35 can be embedded and rotatably set in the annular groove 161 to fix the rotating ring 3. In order to further enhance the fastening fit between the rotating disk 31 and the clamping head 27 on the aluminum plate, a protrusion 32 is provided on the top of the rotating disk 31, and the protrusion 32 is truncated cone-shaped. A plurality of micro-holes 321 are provided through the top disk surface of the protrusion 32. At the same time, a vacuum unit 5 is fixedly provided on one side of the base 1. The vacuum unit 5 is provided with an air intake pipe 19, and the air intake pipe 19 passes through the base 1 and is connected with a plurality of micro-holes 321 on the rotating disk 31. A sealing ring 18 is provided around the connection between the rotating disk 31 and the air intake pipe to ensure air tightness. The vacuum unit 5 can provide vacuum suction, thereby adsorbing the aluminum plate placed on the protrusion 32 to provide a stronger fastening effect. A plurality of anti-sliding blocks 33 are also arranged around the top of the rotating ring 3. The anti-sliding blocks 33 are preferably made of a material with good friction performance such as rubber. The height of the anti-sliding blocks 33 is slightly greater than the height of the protrusion 32, so that when the aluminum plate is pressed downward, the anti-sliding blocks 33 are compressed to provide stronger friction. When the pressing head 27 drives the rotating disk 31 to rotate, the aluminum plate is not easy to slide.

[0061] Based on the above further improvement, since the rotating disk 31 is fixedly sealed and set on the rotating ring 3, and the rotating ring 3 is embedded and rotatably set in the installation groove 16, the stability of the rotation of the rotating disk 31 is increased, and then the vacuum unit 5 provides vacuum suction, so that the aluminum plate placed on the raised portion 32 is adsorbed, thereby improving the fastening effect of the aluminum plate, and then the anti-sliding block 33 provides strong friction to the aluminum plate, so that when the rotating disk 31 rotates, the aluminum plate is not easy to slide, further improving the fastening effect of the aluminum plate.

[0062] like Figure 1 , Fig. 9 and Fig.10 As shown, according to another embodiment of the present invention, further, a slag collecting cavity 15 is provided in the base 1, the bottom of the slag collecting cavity 15 is inclined, a slag outlet 13 connecting the inside and the outside is provided at the lowest point of the slag collecting cavity 15, and a plurality of slag collecting holes 14 connecting the inside and the outside are provided at the top of the slag collecting cavity 15. Furthermore, the top of the base 1 where the slag collecting holes 14 are located can be set to be detachable, so as to regularly clean the slag collecting cavity 15 and the slag collecting holes 14.

[0063] Based on the above further improvements, after the chamfering roller 4 chamfers the aluminum plate, the generated debris will fall into the slag collecting cavity 15 through the slag collecting hole 14. Since the bottom of the slag collecting cavity 15 is inclined, the debris falling on the bottom of the slag collecting cavity 15 will slide along the inclined surface and be discharged from the slag outlet 13, thereby maintaining the surface of the base 1 clean and preventing debris from accumulating to affect subsequent processing.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. 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 solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
