[0017] A cold pressing method for a cold pressing device suitable for special-shaped aluminum alloy windows, the cold pressing method comprising:

[0018] Place the special-shaped aluminum alloy window on the lower cold pressing head, and then add adhesive powder at the joint of the saw blade and each group of saw teeth;

[0019] Control the upper cold pressing head to extend into the inner pressing cylinder, and move in the opposite direction to the lower cold pressing head until the heights at the output ends of the side pressing components simultaneously contact the upper and lower side walls of the special-shaped aluminum alloy window;

[0020] Start the side pressing component, so that the output end of the side pressing component extends into the inner pressing cylinder and simultaneously converges towards the central axis direction of the inner pressing cylinder until it is pressed against the surrounding side walls of the special-shaped aluminum alloy window, and cold press the special-shaped aluminum alloy window simultaneously from multiple directions including the four sides, up and down;

[0021] After the cold pressing is completed, during the transportation of the special-shaped aluminum alloy window, dust removal work is simultaneously carried out on the upper and lower side walls of the special-shaped aluminum alloy window.

[0022] The beneficial effects of the present invention are:

[0023] 1. First, the upper cold pressing head and the lower cold pressing head move relative to each other simultaneously inside the inner pressing cylinder, applying pressure to the two groups of metal plates simultaneously from the upper and lower directions. Then, each group of side blocks extends into the inner pressing cylinder along their respective corresponding inclined groove paths and simultaneously converges towards the central axis direction of the inner pressing cylinder, and finally presses against the surrounding side walls of the two groups of metal plates. This can not only apply pressure to the upper and lower ends of the special-shaped aluminum alloy window simultaneously, but also apply pressure to its four sides simultaneously, making the stress on each part of the special-shaped aluminum alloy window more uniform during cold pressing, avoiding the occurrence of fractures and deformations caused by uneven stress, and thus improving the cold pressing effect of the special-shaped aluminum alloy window.

[0024] 2. After the cold pressing is completed, the special-shaped aluminum alloy window is sent into the cleaning through groove by the pushing unit. Then, each group of rotating material pushing rollers is used to make the special-shaped aluminum alloy window move along the path of the cleaning through groove towards the end away from the cold pressing hole, and at the same time, each group of rotating cleaning rollers is used to clean the dust and floating ash on the surface of the special-shaped aluminum alloy window simultaneously from the upper and lower sides. This avoids dust and floating ash being raised into the air during subsequent work, not only reducing air pollution and improving the environmental protection effect, but also enabling the special-shaped aluminum alloy window to complete the dust removal work during transportation without additional steps, thereby improving production efficiency.

[0025] 3. When the cleaning roller contacts the surface of the special-shaped aluminum alloy window, it first sweeps away the floating dust on its surface through the cleaning brush, and then uses the scraper to scrape off the particles with stronger adsorption. Moreover, the cleaning brush and the scraper alternate with each other to avoid cleaning dead corners. This not only improves the cleaning intensity but also enhances the cleaning effect.

[0026] 4. When the position of the upper cold pressing head shifts and cannot extend into the cold pressing hole, the bottom edge of it will contact the inner wall of the calibration ring. Since the inner diameter of the bottom of the calibration ring is smaller than that of the top, the upper cold pressing head will slide along the slope of the inner wall of the calibration ring towards the cold pressing hole in the center. Then, by rolling and fitting with the guiding ball, the resistance during the descent of the upper cold pressing head is reduced. This avoids the position shift caused by the long-term use of the upper cold pressing head, and there is no need to specifically shut down the machine for debugging, thus improving the smooth operation of the device.

[0027] Other features and advantages of the present invention will be described in the following specification, and partly will be obvious from the specification, or will be understood by implementing the present invention. The objectives and other advantages of the present invention can be realized and obtained through the structures pointed out in the specification, claims, and drawings.

Detailed implementation manners

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] The embodiments of the present invention provide a cold pressing device applicable to special-shaped aluminum alloy windows. Exemplarily, such asFigure 1 and Figure 2 As shown in Figure 2 , it includes a cold pressing table 100. At the center of the top of the cold pressing table 100, there is a cold pressing hole 110. A cold pressing cavity 120 is provided inside the cold pressing table 100, and an electrical cavity 130 is provided below the cold pressing cavity 120. The electrical cavity 130 is used to place electrical equipment for controlling the operation of the cold pressing equipment.

[0044] A top plate 140 is provided directly above the cold pressing table 100. A first hydraulic push rod 300 is installed at the bottom of the top plate 140. A top cold pressing head 310 is provided at the bottom of the first hydraulic push rod 300. The central axis of the top cold pressing head 310 coincides with the central axes of both the cold pressing hole 110 and the cold pressing cavity 120. The bottom of the top cold pressing head 310 extends movably into the cold pressing hole 110. The top cold pressing head 310 extends movably into the cold pressing hole 110 to apply pressure from the top of the special-shaped aluminum alloy window.

[0045] A lower cold pressing unit 400 is provided inside the cold pressing cavity 120. The output end of the lower cold pressing unit 400 extends into the cold pressing hole 110 and is in movable contact with the top cold pressing head 310. The lower cold pressing unit 400 is used to apply pressure from the bottom and side of the special-shaped aluminum alloy window.

[0046] A cleaning unit 500 and a pushing unit 600 are symmetrically arranged on both sides of the cold pressing hole 110. The cleaning unit 500 is used to remove dust on the surface of the special-shaped aluminum alloy window. The pushing unit 600 is used to convey the special-shaped aluminum alloy window into the cleaning unit 500.

[0047] Exemplarily, as Figure 3 shown, a calibration ring 200 is concentrically installed at the top opening of the cold pressing hole 110. The inner diameter of the bottom of the calibration ring 200 is smaller than the inner diameter of the top, and a number of groups of rotating grooves 210 are evenly distributed on the inner wall of the calibration ring 200. A guiding ball 220 is rotatably connected in the rotating groove 210, and the top of the guiding ball 220 extends outside the rotating groove 210.

[0048] When the position of the top cold pressing head 310 is offset and it cannot extend into the cold pressing hole 110, the bottom edge of it will contact the inner wall of the calibration ring 200. Since the inner diameter of the bottom of the calibration ring 200 is smaller than the inner diameter of the top, the top cold pressing head 310 will slide along the slope of the inner wall of the calibration ring 200 towards the cold pressing hole 110 at the center. Then, by rolling and fitting with the guiding ball 220, the resistance when the top cold pressing head 310 descends is reduced. It avoids the position offset caused by the long-term use of the top cold pressing head 310, and there is no need to specifically shut down the machine for debugging, thus improving the smoothness of the device operation.

[0049] Exemplarily, as Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the lower cold pressing unit 400 includes a housing 410, which is installed on the inner wall of the top of the cold pressing cavity 120. At the center of the top of the housing 410, there is an inner pressure cylinder 411. The inner pressure cylinder 411 coincides with the central axis of the cold pressing hole 110, and the two have the same diameter. A ring-shaped side through groove 4111 is provided on the side wall of the inner pressure cylinder 411. A driven gear ring 430 is rotatably connected to the inner wall of the bottom of the cavity of the housing 410. The central axis of the driven gear ring 430 coincides with the central axis of the inner pressure cylinder 411. A number of inclined grooves 412 are annularly and arrayedly distributed on the inner wall of the bottom of the cavity of the housing 410. The inclined grooves 412 extend obliquely from the side close to the central axis of the inner pressure cylinder 411 towards the inner wall of the driven gear ring 430. A first slider 413 is slidably connected in the inclined grooves 412.

[0050] Specifically, a first air spring 440 is installed on the first slider 413, and the other end of the first air spring 440 is installed on the inner wall of the driven gear ring 430. One end of a slider connecting rod 441 is installed on the side wall of the first slider 413 away from the first air spring 440, and the other end of the slider connecting rod 441 is installed with a side stop block 442. The other end of the side stop block 442 extends into the inner pressure cylinder 411 through the side through groove 4111. A number of the side stop blocks 442 are combined to form a circular ring structure.

[0051] The driven gear ring 430, a number of first air springs 440, a number of slider connecting rods 441, a number of side stop blocks 442, a number of inclined grooves 412 and a number of first sliders 413 are combined to form a side pressing component.

[0052] Specifically, a second hydraulic push rod 450 is provided directly below the housing 410. The top of the second hydraulic push rod 450 extends into the inner pressure cylinder 411, and a lower cold pressing head 460 is movably installed. A number of second air springs 470 are annularly and arrayedly distributed around the second hydraulic push rod 450.

[0053] Specifically, a first motor 420 is provided in the cold pressing cavity 120. The output end of the first motor 420 extends into the cavity of the housing 410 and is drivingly connected to a first gear 421. The first gear 421 is meshed and linked with the driven gear ring 430.

[0054] During cold pressing, two groups of metal sheets are placed on the lower cold pressing head 460, and then adhesive powder is added at the junction of the two. Then, the first hydraulic push rod 300 and the second hydraulic push rod 450 are started, so that the upper cold pressing head 310 extends into the inner pressing cylinder 411, and moves in the relative direction with the lower cold pressing head 460, and conflicts with each other at the height of the side through groove 4111. In this way, the two groups of metal sheets are cold pressed from both the upper and lower directions. At the same time, the first motor 420 is started, and the first gear 421 is driven to rotate by the first motor 420, and then the driven gear ring 430 is driven to rotate by the first gear 421, so that each group of first sliders 413 moves along the path of the inclined groove 412 toward the central axis direction of the inner pressing cylinder 411, and each group of side blocks 442 extends into the inner pressing cylinder 411, and simultaneously gathers in the direction of the central axis of the inner pressing cylinder 411, and finally squeezes on the surrounding side walls of the two groups of metal sheets.

[0055] First, the upper cold pressing head 310 and the lower cold pressing head 460 move relative to each other in the inner pressure cylinder 411, and apply pressure to the two groups of metal sheets from the upper and lower directions at the same time. Then, each group of side blocks 442 extends into the inner pressure cylinder 411 along the path of each corresponding group of inclined grooves 412, and simultaneously gathers toward the central axis direction of the inner pressure cylinder 411, and finally squeezes on the surrounding side walls of the two groups of metal sheets. Not only can pressure be applied to the upper and lower ends of the special-shaped aluminum alloy window at the same time, but also pressure can be applied from all sides at the same time, so that the stress on each part of the special-shaped aluminum alloy window is more uniform during cold pressing, avoiding the occurrence of fracture and deformation caused by uneven stress, and thereby improving the cold pressing effect of the special-shaped aluminum alloy window.

[0056] For example, Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the cleaning unit 500 includes a cleaning box 510, which is located on one side of the cold pressing hole 110. A cleaning slot 511 is provided on the cleaning box 510, and both ends of the cleaning slot 511 close to and away from the cold pressing hole 110 are open structures. A transmission box 520 is installed on a side wall of the cleaning box 510 perpendicular to the cold pressing hole 110. Two groups of rotating cavities 512 are symmetrically provided at the upper and lower ends of the cleaning slot 511. A group of cleaning material-selecting components are provided in each of the two groups of rotating cavities 512.

[0057] Specifically, the cleaning material-dispensing component includes a plurality of rotating rods 530 arranged at equal intervals along the cleaning slot 511, a plurality of cleaning mechanisms 540 are arranged at equal intervals along the length direction of the rotating rods 530, and a group of material-dispensing rollers 550 are arranged between two adjacent groups of the cleaning mechanisms 540. One side wall of the cleaning mechanisms 540 and the material-dispensing rollers 550 both extend into the cleaning slot 511.

[0058] Specifically, the input end of each group of the rotating rods 530 extends horizontally into the transmission box 520, and a second gear 531 is installed at the port, and a group of chains 532 are transmission-connected between two adjacent groups of the second gears 531, and a second motor 533 is transmission-connected to the input end of one group of the second gears 531.

[0059] For example, Figure 12 As shown, the cleaning mechanism 540 includes a cleaning roller 541 , and a plurality of groups of cleaning brushes 542 are distributed in a ring array on the side wall of the cleaning roller 541 , and a group of scrapers 543 are provided between two adjacent groups of cleaning brushes 542 .

[0060] For example, Figure 8 As shown, the pushing unit 600 includes a vertical plate 610, which is located on the side of the cold pressing hole 110 away from the cleaning unit 500. A servo electric cylinder 620 is installed horizontally on the side wall of the vertical plate 610 close to the cold pressing hole 110, and a shovel plate 630 is installed on the output end of the servo electric cylinder 620.

[0061] After the cold pressing is completed, the upper cold pressing head 310 rises and leaves the inner pressing cylinder 411, and then each group of side blocks 442 shrinks back into the cavity of the outer cover 410, and then the second hydraulic push rod 450 drives the special-shaped aluminum alloy window to rise to the same height as the shovel plate 630. The servo electric cylinder 620 is started, and the servo electric cylinder 620 drives the shovel plate 630 to shovel the special-shaped aluminum alloy window from the bottom, and as the servo electric cylinder 620 continues to work, it is sent into the cleaning groove 511. Then the second motor 533 is started, and each group of rotating rods 530 drives the corresponding cleaning rollers 541 and the material-dispensing rollers 550 to rotate simultaneously from the upper and lower sides through the second motor 533, and the special-shaped aluminum alloy window is moved to the end of the cleaning groove 511 away from the cold pressing hole 110 through the rotation of the material-dispensing rollers 550. While the special-shaped aluminum alloy window is moving, the upper and lower side walls of the special-shaped aluminum alloy window are cleaned and dusted by the rotating groups of cleaning rollers 541.

[0062] After the cold pressing is completed, the special-shaped aluminum alloy window is sent into the cleaning slot 511 by the pushing unit 600, and then the special-shaped aluminum alloy window is moved along the path of the cleaning slot 511 to the end away from the cold pressing hole 110 by using each set of rotating material-dispensing rollers 550, and at the same time, the dust and floating dust on the surface of the special-shaped aluminum alloy window are cleaned from both the upper and lower sides by using each set of rotating cleaning rollers 541. In the subsequent work, dust and floating dust are prevented from being raised into the air, which not only reduces air pollution and improves environmental protection effects, but also makes it possible to complete dust removal work during transportation without additional steps for the special-shaped aluminum alloy window, thereby improving production efficiency.

[0063] When the cleaning roller 541 contacts the surface of the special-shaped aluminum alloy window, first, the floating dust on its surface is swept away by the cleaning brush 542, and then the particles with strong adsorption are scraped off by the scraping plate 543. Moreover, the cleaning brush 542 and the scraping plate 543 alternate with each other to avoid cleaning dead corners. This not only improves the cleaning intensity but also enhances the cleaning effect.

[0064] The above embodiments have the following beneficial effects:

[0065] 1. First, the upper cold pressing head 310 and the lower cold pressing head 460 move relatively in the inner pressure cylinder 411 at the same time, applying pressure to the two groups of metal plates from the upper and lower directions simultaneously. Then, each group of side blocks 442 extends into the inner pressure cylinder 411 along the path of its respective corresponding inclined groove 412 and converges towards the central axis direction of the inner pressure cylinder 411 at the same time, and finally presses on the peripheral side walls of the two groups of metal plates. This can not only apply pressure to the upper and lower ends of the special-shaped aluminum alloy window simultaneously but also apply pressure to it from all around, making the stress on each part of the special-shaped aluminum alloy window more uniform during cold pressing, avoiding the occurrence of fractures and deformations caused by uneven stress, and thus improving the cold pressing effect of the special-shaped aluminum alloy window.

[0066] 2. After cold pressing, the special-shaped aluminum alloy window is sent into the cleaning through groove 511 by the pushing unit 600. Then, each group of rotating material pushing rollers 550 is used to make the special-shaped aluminum alloy window move along the path of the cleaning through groove 511 towards the end far from the cold pressing hole 110. At the same time, each group of rotating cleaning rollers 541 is used to clean the dust and floating ash on the surface of the special-shaped aluminum alloy window from the upper and lower sides simultaneously. This avoids dust and floating ash from being lifted into the air during subsequent work, not only reducing air pollution and improving the environmental protection effect but also enabling the special-shaped aluminum alloy window to complete the dust removal work during the transportation process without additional steps, thereby improving production efficiency.

[0067] 3. When the cleaning roller 541 contacts the surface of the special-shaped aluminum alloy window, first, the floating dust on its surface is swept away by the cleaning brush 542, and then the particles with strong adsorption are scraped off by the scraping plate 543. Moreover, the cleaning brush 542 and the scraping plate 543 alternate with each other to avoid cleaning dead corners. This not only improves the cleaning intensity but also enhances the cleaning effect.

[0068] 4. When the position of the upper cold pressing head 310 is offset and it cannot extend into the cold pressing hole 110, the bottom edge of it will contact the inner wall of the calibration ring 200. Since the inner diameter of the bottom of the calibration ring 200 is smaller than that of the top, the upper cold pressing head 310 will slide along the slope of the inner wall of the calibration ring 200 towards the central cold pressing hole 110. Then, by rolling and fitting with the guiding ball 220, the resistance when the upper cold pressing head 310 descends is reduced. This avoids the position offset caused by the long-term use of the upper cold pressing head 310 and does not require the machine to be specially shut down for debugging, thus improving the smoothness of the device operation.

[0069] Based on the above-mentioned cold pressing equipment applicable to special-shaped aluminum alloy windows, an embodiment of the present invention further proposes a cold pressing method of the cold pressing equipment. Exemplarily, the cold pressing method includes:

[0070] Two sets of aluminum alloy plates are placed on the lower cold pressing head, and then bonding powder is added at their joints;

[0071] The first hydraulic push rod and the second hydraulic push rod are started to extend the upper cold pressing head into the inner pressing cylinder and move in the relative direction with the lower cold pressing head until they simultaneously abut against the upper and lower side walls of the two groups of aluminum alloy plates at the height of the side through grooves;
