Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy frame processing equipment, and specifically relates to a frame trimming device and a trimming method for the production of aluminum alloy profiles. Background Art

[0002] In the field of aluminum alloy profile processing, the frame trimming device is a key equipment to ensure the quality and precision of aluminum alloy frames. It is mainly used for edge cutting of aluminum alloy profiles, removing redundant parts, making the frame meet the specified size and shape requirements, and meeting the process requirements of subsequent assembly, etc. This device is widely used in industries such as door and window manufacturing and curtain wall processing. Through mechanical cutting and other technical means, the aluminum alloy profiles are precisely processed, which plays an important role in improving the overall quality and aesthetics of aluminum alloy products.

[0003] However, traditional aluminum alloy frame trimming devices have many deficiencies. In terms of applicability, most device structures are fixed and it is difficult to flexibly adapt to aluminum alloy frames of different shapes and sizes. Enterprises often need to be equipped with a variety of special devices, which not only greatly increases production costs, but also occupies a large amount of production space. During the cutting operation, due to the lack of effective fixing and supporting devices, the frame is not firmly fixed, resulting in easy displacement during cutting, which not only affects the cutting accuracy, but may also cause the cutting surface to be uneven, generating a large number of defective products and increasing production losses. Moreover, when the existing device cuts, it is unable to reasonably suspend the frame, making the cutting operation easily interfered by the bottom support surface of the frame, which not only reduces the cutting efficiency, but may also damage the cutting tool and the support table. In addition, the stability of the device operation is poor, and the friction between components is not properly controlled, resulting in problems such as jamming and shaking of the device during the cutting process, further affecting the cutting quality and making it difficult to meet the requirements of modern manufacturing for high-precision and high-efficiency aluminum alloy frame processing.

[0018] A trimming method for a frame trimming device for producing aluminum alloy profiles, comprising the following steps:

[0019] S1. Place the aluminum alloy frame to be cut on the upper surface of the second sliding bar, and turn the adjustment rod on the mounting plate to slide the expansion rod outward;

[0020] S2. The expansion rod sliding outwards is finally pressed against the inner surface of the aluminum alloy frame, and the mounting plate is fixed by multi-point support. Then the rotating frame is adjusted to a suitable position, and the wire cutting machine is adjusted;

[0022] S4. After cutting is completed, rotate the mounting plate in the opposite direction to release and remove the aluminum alloy frame, thus completing the entire trimming operation.

[0023] (III) Beneficial effects

[0024] The present invention provides a frame trimming device and a trimming method for aluminum alloy profile production, which has the following beneficial effects:

[0025] (I) The frame trimming equipment and method for producing aluminum alloy profiles are realized by hingedly connecting an elastic telescopic rod at the bottom of the expansion rod and cooperating with the No. 1 plug-in rod and the No. 2 plug-in rod, so that the equipment can automatically adapt to frames of different shapes, greatly improving the application range of the equipment, achieving the effect of one machine with multiple uses, and also greatly reducing the production cost of the enterprise.

[0026] (II) The frame trimming equipment and trimming method of the aluminum alloy profile production, when the expansion rod expands outward, it will simultaneously drive the moving block to move, and the expansion rod will squeeze and fix the frame through the design of the inclined side surface. During the process, the frame will gradually move to the upper surface of the moving block and break away from the contact with the No. 2 sliding bar. Finally, the inner surface of the frame will contact the outer surface of the No. 1 sliding bar, and under the action of the extrusion force, the No. 1 sliding bar will begin to be squeezed, so that the No. 1 sliding bar will gradually move into the No. 2 installation groove. During the movement of the No. 1 sliding bar, the No. 2 sliding bar will gradually move to the outside of the No. 2 installation groove, and finally the No. 1 sliding bar will be The outer surface of the slide bar is in firm contact with the inner surface of the frame, and the expansion bag is stretched at the same time, so that the interior of the expansion bag is in a negative pressure state, that is, air pressure begins to be extracted from the interior of the expansion bag, and then the expansion bag begins to shrink, which drives the moving block to move upward, and then the frame as a whole is dragged upward, so that the bottom surface of the frame is away from the No. 2 sliding bar, so that when the frame is fixed, the edge of the entire frame is in a suspended state, which greatly facilitates the wire cutting machine to perform edge trimming operations on the frame, avoids the problem that the bottom surface of the frame fits on the upper surface of the No. 2 sliding bar, making it difficult to cut, and also protects the No. 2 sliding bar.

[0027] (3). For the edge cutting equipment and method for the frame of this aluminum alloy profile production, when the expansion rod slides on the first sliding bar and the second sliding bar, the setting of the limiting disc enables the expansion rod to always move vertically, avoiding the inclination of the expansion rod, which may lead to the inability to fix the frame. Moreover, the provided fitting roller can significantly reduce the friction between the limiting disc and the first sliding bar and the second sliding bar. Furthermore, while ensuring that the expansion rod always moves vertically, it can also avoid the problem of the expansion rod getting stuck during movement due to excessive friction with the first sliding bar and the second sliding bar, greatly improving the working smoothness of this equipment. When the frame moves upward with the moving block, finally the upper surface of the frame will contact the extrusion ring and extrude the extrusion ring, thereby increasing the air pressure inside the pressure groove and transporting the internal air pressure to the expansion groove inside the fitting roller. Finally, the air pressure inside the expansion groove increases, that is, the sealing ring expands outward, thus significantly increasing the friction between the fitting roller and the first sliding bar and the second sliding bar. Therefore, after the frame is fixed, the friction between the fitting roller and the first sliding bar and the second sliding bar is automatically enhanced, thereby locking the expansion rod and avoiding the problem of unstable cutting caused by the shaking of the expansion rod during the edge cutting process, greatly improving the cutting accuracy.

The inner surface of the limit plate 41 is rotatably connected with a bonding roller 42, and the bonding roller 42 is respectively bonded to the lower surface of the No. 1 sliding bar 35 and the upper surface of the No. 2 sliding bar 36.

[0048] A pressing disk 410 is fixedly sleeved on the outer surface of the top of the expansion rod 37. A pressure groove 411 is formed inside the pressing disk 410. An extrusion ring 412 is elastically slidably connected inside the pressure groove 411. Expansion grooves 413 are formed on the outer surfaces of both ends of the fitting roller 42. A sealing ring 414 is fixedly connected to the outside of the expansion groove 413. The sealing ring 414 is made of rubber material, and the expansion groove 413 communicates with the pressure groove 411.

[0049] During operation, when it is necessary to trim the frame, the frame can be placed horizontally on the second sliding bar as a whole, and then the adjusting rod on the mounting plate 315 is toggled clockwise, so that the toggle rod 314 on the rotating plate 313 gradually approaches the blocking rod 311 at the bottom of the No. 1 plug-in rod 39 and exerts an extrusion force on it. Under the action of the extrusion force, the No. 1 plug-in rod 39 and the No. 2 plug-in rod 310 begin to expand, that is, the expansion rod 37 is driven by the elastic telescopic rod 38 to slide outward inside the No. 1 sliding bar 35 and the No. 2 sliding bar 36, and finally the top of the expansion rod 37 contacts and relatively squeezes the inner surface of the frame, completing the fixed clamping of the frame. At this time, the driving wire cutting machine 33 can complete the trimming operation of the frame, and when the expansion rod 37 moves outward, due to the expansion There are six expansion rods 37 distributed in a ring shape, so when the expansion rods 37 expand outward, the overall expansion is circular. If an irregular frame is encountered, the six expansion rods 37 cannot simultaneously complete the contact and extrusion with the inner surface of the frame, but will contact the inner surface of the frame one after another, and the No. 1 plug-in rod 39 and the No. 2 plug-in rod 310 always maintain a synchronous expansion state, that is, the elastic telescopic rod 38 at the bottom of the expansion rod 37 that first contacts the inner surface of the frame will be tilted and stretched until the tops of all the expansion rods 37 contact the inner surface of the frame, and finally the extrusion and fixation of the frame is completed. The elastic telescopic rod 38 is hinged at the bottom of the expansion rod 37 and cooperates with the No. 1 plug-in rod 39 and the No. 2 plug-in rod 310, so that the device can automatically adapt to the environment. The frame of the present invention is equipped with frames of different shapes, which greatly improves the application range of the present invention, achieves the effect of one machine with multiple uses, and also greatly reduces the production cost of the enterprise. When the expansion rod 37 expands outward, it will simultaneously drive the moving block 45 to move. The design of the inclined side surface makes the expansion rod 37 squeeze and fix the frame. During the process, the frame will gradually move to the upper surface of the moving block 45 and break away from the contact with the second sliding bar 36. Finally, the inner surface of the frame contacts the outer surface of the first sliding bar 47, and begins to squeeze the first sliding bar 47 under the action of the squeezing force, so that the first sliding bar 47 gradually moves into the second installation groove 46. During the movement of the first sliding bar 47, the second sliding bar 48 will gradually move to the outside of the second installation groove 46, and finally the first sliding bar 48 will be moved to the outside of the second installation groove 46. The outer surface of the slide bar 47 is firmly in contact with the inner surface of the frame, and the expansion bag 49 is stretched at the same time, so that the inside of the expansion bag 49 is in a negative pressure state, that is, the air pressure begins to be extracted from the inside of the telescopic bag 44, and then the telescopic bag 44 begins to shrink, that is, the moving block 45 is driven to move upward, and then the frame is dragged upward as a whole, so that the bottom surface of the frame is away from the second slide bar 36, so that when the frame is fixed, the edge of the entire frame is in a suspended state, which greatly facilitates the wire cutting machine 33 to perform edge trimming operations on the frame, avoids the problem that the bottom surface of the frame is attached to the upper surface of the second slide bar 36, and makes it difficult to cut, and at the same time protects the second slide bar 36. When the expansion rod 37 slides on the first slide bar 35 and the second slide bar 36,The setting of the limit disc 41 enables the expansion rod 37 to always move vertically, preventing the expansion rod 37 from tilting and being unable to fix the frame. Moreover, the provided fitting roller 42 can significantly reduce the friction between the limit disc 41 and the first sliding bar 35 and the second sliding bar 36. Thus, while ensuring that the expansion rod 37 always moves vertically, it can also avoid the problem of the expansion rod 37 getting stuck due to excessive friction with the first sliding bar 35 and the second sliding bar 36, greatly improving the working smoothness of this equipment. When the frame moves upward with the moving block 45, it will eventually cause the upper surface of the frame to contact the extrusion ring 412 and extrude the extrusion ring 412, thereby increasing the air pressure inside the pressure groove 411 and transporting the internal air pressure to the expansion groove 413 inside the fitting roller 42. Finally, the air pressure inside the expansion groove 413 increases, causing the sealing ring 414 to expand outward, thus greatly increasing the friction between the fitting roller 42 and the first sliding bar 35 and the second sliding bar 36. Therefore, after the frame is fixed, the friction between the fitting roller 42 and the first sliding bar 35 and the second sliding bar 36 is automatically enhanced, thereby locking the expansion rod 37 and avoiding the problem of unstable cutting caused by the shaking of the expansion rod 37 during the edge cutting process, greatly improving the cutting accuracy.

[0053] S3. Use the adjusted wire cutting machine 33 to perform required cutting on the edge of the aluminum alloy frame. After one cutting is completed, continue to cut other positions of the aluminum alloy frame by adjusting the positions of the rotating frame 32 and the wire cutting machine 33;
