Description

Technical Field

[0001] The invention belongs to the field of metal frame bending, in particular to a metal frame bending device for an energy-saving window. Background Art

[0002] Energy-saving windows refer to windows that use materials and technologies that enhance thermal insulation, sound insulation, and sealing properties during the design and manufacturing process to reduce energy consumption and improve indoor comfort. The improved frame material is generally made of aluminum alloy.

[0003] One-piece bending windows are a common window processing technology in modern buildings. It forms an overall window structure by cold-bending or hot-bending metal materials (such as aluminum alloy, steel, etc.) into the shape of a window frame, and integrating the glass with the window frame. It requires the use of professional bending equipment.

[0004] When bending the metal frame of the window, the traditional bending device often only performs simple bending work with a relatively simple function. It is also necessary to continuously place metal frames of appropriate length into the device and quickly transfer the finished product to the outside after the bending is completed. Both operations require manual or other equipment assistance, which is not conducive to the high-speed production process of the workshop.

[0005] To this end, the present invention provides a metal frame bending device for an energy-saving window. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the energy-saving window metal frame bending device described in the present invention comprises a processing table, a plurality of binding wheels are installed on the top surface of the processing table, the plurality of binding wheels are linearly and equidistantly arranged, the binding wheels are used to fix and move the window frame to be bent, a movable extrusion seat is arranged at one end of the top surface of the processing table, a bending arm for bending the window frame to be bent is also arranged at one end of the top surface of the processing table, a guide frame for guiding the transfer of the bending frame is arranged above the processing table, and a circular saw for cutting the window frame to be bent is arranged on the top surface of the processing table; Through this setting, not only the function of automatically transferring the finished bending frames is realized, but also the completed bending frames can be transferred by utilizing the shape and gravity of the guide frame itself without using any electrical equipment. This not only allows the device to work continuously, but also facilitates the storage of finished products and the subsequent large-scale transfer work. The setting of extra-long window frames to be bent can also increase the loading interval of the device and reduce the frequency of loading. The device can cut the window frames to be bent of the required length by itself, reducing the pre-processing process of the bent window frames.

[0008] Preferably, the processing table is arranged in a long strip shape, the binding wheel is composed of two electric wheels one which are symmetrical up and down, the window frame to be bent is clamped between the upper and lower electric wheels one, the processing table is arranged in an L shape, the top of the processing table is rotatably connected to a protective cover, the electric wheel one located above can slide up and down on the outer wall surface of the processing table, and the bottom of the extrusion seat is rotatably connected to an electric wheel two, the upper and lower electric wheels one fix the window frame to be bent, and as the electric wheels are driven, the window frame to be bent can be driven to move horizontally, and the protective cover is closed when the device is working to reduce the impact of the external environment; when encountering window frames to be bent with different thicknesses, the distance between the two electric wheels one can be adjusted by sliding the electric wheel one upwards, so that the window frame to be bent can be stably clamped without damaging the window frame to be bent.

[0009] Preferably, the bending arm is arranged in a bending shape, one end of the bending arm is fixedly connected to the processing table, and the other end of the bending arm is connected to a supporting column, and the height of the bending arm close to the processing table is higher than the height close to the supporting column. The bending frame sleeved on the guide frame will eventually slide to one side of the supporting column under the action of gravity. Since the bending frame will partially rebound after the bending is completed, the bending frame will not touch the window frame to be bent after the bending is completed, thereby ensuring the normal bending process. At the same time, when the bending frame is on the guide frame, due to the notch at the bottom of the bending frame, when random inspection or sample taking is required, a single bending frame can be directly taken away. When the guide frame is full of finished products, the end of the guide frame can be disconnected from the processing table, and the entire guide frame can be transferred to complete the batch transportation of the finished products.

[0010] Preferably, a base is provided at the bottom of the support column, and a servo motor is fixedly connected to the top of the base to drive the support column to rotate, the bending arm is rotatably connected to the support column, and the guide frame is arranged in sections, and the bottoms of the two sections of the guide frame are connected by an electromagnetic lock. In order to facilitate the batch transportation of finished products, when the guide frame close to a section of the support column is full of bending frames, the electromagnetic lock is opened to separate the two sections of the guide frame. After separation, the servo motor drives the support column to rotate, and then rotates the guide frame so that the end of the guide frame faces downward, and the bending frame hung on the guide frame is pushed out downward, so as to batch recycle the finished products. When the recycling is completed, the guide frame is returned to its position, and the two sections of the guide frame are docked under the drive of the electromagnetic lock to continue receiving the finished products.

[0011] Preferably, it also includes a moving platform, the outer side of which is fixedly provided with a receiving rod and a counterweight block, the receiving rod and the counterweight block are located on both sides of the moving platform, and a plurality of universal wheels are installed at the bottom of the moving platform, the height of the receiving rod close to the moving platform is lower than the height of the end away from the receiving rod. When the support column drives a section of the guide frame to rotate, the end of the guide frame is directed toward the receiving rod, and then the guide frame rotates downward and is aligned with the end of the receiving rod, and the end of the guide frame is overlapped above the receiving rod. At this time, the end of the guide frame faces downward, and the finished products on the guide frame will slide onto the receiving rod under the action of gravity. Then the guide frame returns to its position and the two sections are fixed, and the moving platform can be transferred outward under the setting of the universal wheels. Through this setting, the finished products on the guide frame can be transferred quickly, which greatly reduces the downtime and transfer time of the device and ensures production efficiency. The setting of the counterweight block is to ensure the center of gravity position of the moving platform and reduce the risk of tipping during the transfer process; the method for observing the number of finished products on the guide frame can be directly observed by an optical camera, and when the number is reached, the finished products are directly transferred.

[0012] Preferably, an electric telescopic rod 2 is fixedly connected to the top of the support column, and a lower pressure roller is fixedly connected to the bottom output end of the electric telescopic rod 2, and an electric winding roller is arranged inside the support column, and a steel cable is fixedly connected to the outer side of the electric winding roller, and the steel cable passes through the bottom of the lower pressure roller, and the end of the steel cable is fixedly connected to the top of the guide frame. When the finished product is transferred, the electric winding roller is started to reel in the steel cable, and the end of the guide frame is lifted upward. When the two sections of the guide frame are fixed, the lower pressure roller is sunk by the electric telescopic rod 2, and the steel cable is attached to the surface of the guide frame, so that the force balance can still be maintained. This operation is to ensure that the supporting force of the finished product is provided by the guide frame rather than the steel cable, and the way of raising the height of the end of the guide frame by the steel cable is a labor-saving lever, which ensures the stable rotation process of the guide frame.

[0013] Preferably, a reduction motor is fixedly connected to one end of the processing table, a bending shaft is fixedly connected to the output end of the reduction motor, the outer side of the bending shaft is fixedly connected to the bending arm, the width of the bending arm is greater than the width of the window frame to be bent, the reduction motor drives the bending arm to rotate, and the bending arm drives the upper window frame to be bent to bend, thereby realizing the processing of the bending frame.

[0014] Preferably, the extrusion seat is arranged in an arc shape on one side close to the bending axis, an electric telescopic rod 1 is fixedly connected to the interior of the extrusion seat, an extrusion strip is fixedly connected to the end of the electric telescopic rod 1, the extrusion strip faces the direction of the bending axis, and the outer surface of the extrusion strip is arranged in a smooth transition. When the window frame to be bent is subjected to the bending process, the extrusion seat moves to the top of the window frame to be bent and squeezes the bending part. The arc shape is arranged to ensure that the corner of the bending frame after bending will not break due to excessive corner. At the same time, the bending arc required for the window frames to be bent of different thicknesses needs to be appropriately changed. The window frames to be bent with larger thickness are directly pressed together using the extrusion seat, and the window frames to be bent with smaller thickness have the extrusion strip pushed outward by the electric telescopic rod 1, so that the extrusion strip with smaller surface area fits together, thereby adapting to the processing process of the window frames to be bent of two thicknesses. A groove for accommodating the extrusion strip is provided on the surface of the extrusion seat.

[0015] Preferably, an extrusion sheet is provided on one side of the extrusion seat close to the bending axis, and the extrusion sheet is located on the outside of the extrusion strip. The upper and lower ends of the extrusion sheet are both located inside the extrusion seat and are slidably connected to the extrusion seat. Springs are fixedly connected between both ends of the extrusion sheet and the extrusion seat. Through the setting of the extrusion sheet, the extrusion sheet is a thin sheet of metal material. During the process of the extrusion strip being ejected outward, the extrusion sheet will also change its own curvature. Since the metal material has toughness, the curvature of the surface of the extrusion sheet will be greater than that of the extrusion strip. By controlling the protruding distance of the extrusion strip, the curvature of the extrusion sheet can be controlled, thereby more accurately controlling the extrusion curvature required for extruding different window frames to be bent, thereby improving the bending quality and accuracy.

[0016] Preferably, a vertical electric slide is provided on the top of the processing table, a connecting platform is fixedly connected to the top of the extrusion seat, the connecting platform is connected to the moving end of the electric slide, a plurality of hydraulic rods for driving the electric slide to translate are installed on the outer side of the electric slide, the hydraulic rods are fixedly connected to the processing table, the lifting and lowering of the extrusion seat is controlled by the electric slide, and the translation of the electric slide and the extrusion seat is controlled by the hydraulic rod, so that the extrusion seat can be controlled to accurately extrude the top surface of the window frame to be bent from any position, thereby ensuring the smooth progress of the bending work.

[0017] The beneficial effects of the present invention are as follows: 1. The energy-saving window metal frame bending device described in the present invention, through the setting of the guide frame and the processing table, not only realizes the function of automatically transferring the finished bending frame, but also does not need to use any electrical equipment. The shape and gravity of the guide frame itself can transfer the processed bending frame, which not only allows the device to work continuously, but also facilitates the storage of finished products and the subsequent large-scale transfer work; and the setting of extra-long window frames to be bent can also increase the loading interval of the device and reduce the frequency of loading. The device can cut the window frames to be bent of the required length by itself, reducing the pretreatment process of the window frames to be bent.

[0018] 2. In the energy-saving window metal frame bending device described in the present invention, the bending frame sleeved on the guide frame will eventually slide to one side of the supporting column under the action of gravity. Since the bending frame will partially rebound after the bending is completed, the bending frame will not touch the window frame to be bent after the bending is completed, thereby ensuring the normal bending process. At the same time, when the bending frame is on the guide frame, since there is a gap at the bottom of the bending frame, when random inspection or sample taking is required, a single bending frame can be directly taken away. When the guide frame is full of finished products, the end of the guide frame can be disconnected from the processing table, and the entire guide frame can be transferred to complete the batch transportation of the finished products.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7As shown, an energy-saving window metal frame bending device according to an embodiment of the present invention comprises a processing table 1, a plurality of binding wheels 3 are installed on the top surface of the processing table 1, and the plurality of binding wheels 3 are linearly and equidistantly arranged, and the binding wheels 3 are used to fix and move the window frame 4 to be bent, and a movable extrusion seat 15 is arranged at one end of the top surface of the processing table 1, and a bending arm 12 for bending the window frame 4 to be bent is also arranged at one end of the top surface of the processing table 1, and a guide frame 6 for guiding the transfer of the bending frame 5 is arranged above the processing table 1, and a circular saw 13 for cutting the window frame 4 to be bent is arranged on the top surface of the processing table 1; By setting the guide frame and the processing table 1, the window frame 4 to be bent, which is much longer than the required length of the bending frame 5, is placed on the processing table 1. The placement method is: the head of the window frame 4 to be bent passes through multiple binding wheels 3 from one end in turn, and one end of the window frame 4 to be bent is moved to the top of the bending arm 12 by driving the binding wheel 3. At this time, the extrusion seat 15 moves to the top of the window frame 4 to be bent to compress and fix the window frame 4 to be bent. The extrusion seat 15 can be arbitrarily translated and lifted on the vertical plane, and then the bending arm 12 rotates, synchronously driving the window frame 4 to be bent at the upper part of the bending arm 12 to be bent, and then the window frame 4 to be bent continues to move forward, and the bending arm 12 bends again. The extrusion seat 15 is fixed at each bending, and the extrusion seat 15 moves away when the window frame 4 to be bent moves; after four bendings, a rectangular bending frame 5 can be produced, and then the circular saw 13 rotates The guide frame 6 is then moved upward to cut and separate the window frame 4 to be bent and the bent frame 5 to be processed. During the bending process of the bending frame 5, it will automatically fit on the outside of the guide frame 6. After the separation is completed, due to the low height of the free end of the guide frame 6, the bending frame 5 will slide outward under the action of gravity for transfer. Through this arrangement, not only the function of automatically transferring the finished bending frame 5 is realized, but also the shape and gravity of the guide frame 6 itself can be used to transfer the bent frame 5 without using any electrical equipment, which not only allows the device to work continuously, but also facilitates the storage of finished products and the subsequent large-scale transfer work; and the setting of the extra-long window frame 4 to be bent can also increase the feeding interval of the device, reducing the feeding frequency, and the device can automatically cut out the window frame 4 to be bent of the required length, reducing the pretreatment process of the bent window frame 4.

[0023] The processing table 1 is arranged in a long strip shape, the binding wheel 3 is composed of two upper and lower symmetrical electric wheels 1, the window frame 4 to be bent is sandwiched between the upper and lower electric wheels 1, the processing table 1 is arranged in an L shape, the top of the processing table 1 is rotatably connected to a protective cover 2, the electric wheel 1 located above can slide up and down on the outer wall surface of the processing table 1, and the bottom of the extrusion seat 15 is rotatably connected to an electric wheel 2 21; When working, the upper and lower electric wheels 1 fix the window frame 4 to be bent, and as the electric wheels are driven, the window frame 4 to be bent can be driven to move horizontally. When the device is working, the protective cover 2 is closed to reduce the impact of the external environment. When encountering window frames 4 to be bent with different thicknesses, the distance between the two electric wheels 1 can be adjusted by sliding the electric wheel 1 upwards, so that the window frame 4 to be bent can be clamped stably without damaging the window frame 4 to be bent. The electric wheel 2 21 will fit with the top surface of the window frame 4 to be bent when the extrusion seat 15 presses the window frame 4 to be bent. This arrangement is to use the electric wheel 2 21 to ensure that the window frame 4 to be bent can be transported forward when the window frame 4 to be bent has only a short length left and the electric wheel 1 in front cannot transmit the window frame 4 to be bent.

[0024] The bending arm 12 is arranged in a bending shape, one end of the bending arm 12 is fixedly connected to the processing table 1, and the other end of the bending arm 12 is connected to the support column 7, and the height of the bending arm 12 close to the processing table 1 is higher than the height of the end close to the support column 7; During operation, the bending frame 5 sleeved on the guide frame 6 will eventually slide to one side of the support column 7 under the action of gravity. Since the bending frame 5 will partially rebound after bending, the bending frame 5 will not touch the window frame 4 to be bent, thereby ensuring the normal bending process. At the same time, when the bending frame 5 is on the guide frame 6, since there is a gap at the bottom of the bending frame 5, when random inspection or sample taking is required, a single bending frame 5 can be directly taken away. When the guide frame 6 is full of finished products, the end of the guide frame 6 can be disconnected from the processing table 1, and the entire guide frame 6 can be transferred to complete the batch transportation of the finished products.

[0025] The bottom of the support column 7 is provided with a base 11, the top of the base 11 is fixedly connected with a servo motor for driving the support column 7 to rotate, the bending arm 12 is rotatably connected to the support column 7, the guide frame 6 is arranged in sections, and the bottoms of the two sections of the guide frame 6 are connected by an electromagnetic lock; During operation, in order to facilitate the batch transportation of finished products, when the guide frame 6 near the support column 7 is full of bending frames 5, the electromagnetic lock is opened to separate the two sections of the guide frame 6. After separation, the servo motor drives the support column 7 to rotate, and then the guide frame 6 is rotated to make the end of the guide frame 6 face downward, so that the bending frames 5 hung on the guide frame 6 are moved downward, thereby recovering the finished products in batches. After the recovery is completed, the guide frame 6 is returned to its position, and the two sections of the guide frame 6 are connected under the drive of the electromagnetic lock to continue receiving the finished products.

[0026] It also includes a moving platform 8, a receiving rod 10 and a counterweight 9 are fixedly connected to the outer side of the moving platform 8, the receiving rod 10 and the counterweight 9 are located on both sides of the moving platform 8, a plurality of universal wheels are installed at the bottom of the moving platform 8, and the height of the receiving rod 10 close to the moving platform 8 is lower than the height of the end away from the receiving rod 10; During operation, after the support column 7 drives a section of the guide frame 6 to rotate, the end of the guide frame 6 is directed toward the receiving rod 10, and then the guide frame 6 rotates downward to align with the end of the receiving rod 10, and the end of the guide frame 6 is overlapped on the top of the receiving rod 10. At this time, the end of the guide frame 6 faces downward, and the finished products on the guide frame 6 will slide onto the receiving rod 10 under the action of gravity. Then the guide frame 6 returns to its position and the two sections are fixed, and the mobile platform 8 can be transferred outward under the setting of the universal wheel. Through this setting, the finished products on the guide frame 6 can be transferred quickly, which greatly reduces the downtime and transfer time of the device and ensures production efficiency. The setting of the counterweight block 9 is to ensure the center of gravity position of the mobile platform 8 and reduce the risk of tipping during the transfer process; the method for observing the number of finished products on the guide frame 6 can be directly observed by an optical camera, and when the number is reached, the finished products are directly transferred.

[0027] The top of the support column 7 is fixedly connected to an electric telescopic rod 26, the bottom output end of the electric telescopic rod 26 is fixedly connected to a lower pressure roller 25, an electric winding roller is arranged inside the support column 7, the outer side of the electric winding roller is fixedly connected to a steel cable 24, the steel cable 24 passes under the lower pressure roller 25, and the end of the steel cable 24 is fixedly connected to the top of the guide frame 6; During operation, after the transfer of the finished product is completed, the electric winding roller is started to reel in the steel cable 24, and the end of the guide frame 6 is lifted upward. When the two sections of the guide frame 6 are fixed, the lower pressure roller 25 is sunk through the electric telescopic rod 26 to make the steel cable 24 fit the surface of the guide frame 6, so that the force balance can still be maintained. This operation is to ensure that the supporting force of the finished product is provided by the guide frame 6, rather than the steel cable 24. The way in which the steel cable 24 lifts the height of the end of the guide frame 6 is a labor-saving lever, which ensures the stable rotation process of the guide frame 6.

[0028] A reduction motor 16 is fixedly connected to one end of the processing table 1, and a bending shaft 14 is fixedly connected to the output end of the reduction motor 16. The outer side of the bending shaft 14 is fixedly connected to a bending arm 12, and the width of the bending arm 12 is greater than the width of the window frame 4 to be bent. During operation, the reduction motor 16 drives the bending arm 12 to rotate, and the bending arm 12 drives the upper window frame 4 to be bent to bend, thereby realizing the work of processing the bending frame 5.

[0029] The side of the extrusion seat 15 close to the bending axis 14 is arranged in an arc shape, and an electric telescopic rod 19 is fixedly connected to the interior of the extrusion seat 15, and an extrusion bar 22 is fixedly connected to the end of the electric telescopic rod 19, and the extrusion bar 22 faces the direction of the bending axis 14, and the outer surface of the extrusion bar 22 is arranged in a smooth transition; During operation, the extrusion seat 15 moves to the top of the window frame 4 to be bent and squeezes the bending part when the window frame 4 to be bent is undergoing bending processing. The arc-shaped setting is to ensure that the corner of the bending frame 5 after bending will not break due to excessive corner size; at the same time, the bending arc required for the window frames 4 to be bent of different thicknesses needs to be appropriately changed. The window frame 4 to be bent with a larger thickness is directly pressed together using the extrusion seat 15, and the window frame 4 to be bent with a smaller thickness is pressed together using the electric telescopic rod 19 to push the extrusion strip 22 outward, so that the extrusion strip 22 with a smaller surface area fits together, thereby being able to adapt to the processing of the window frames 4 to be bent of two thicknesses. A groove for accommodating the extrusion strip 22 is provided on the surface of the extrusion seat 15.

[0030] The extrusion seat 15 is provided with an extrusion sheet 20 on one side close to the bending axis 14. The extrusion sheet 20 is located on the outside of the extrusion strip 22. The upper and lower ends of the extrusion sheet 20 are both located inside the extrusion seat 15 and are slidably connected to the extrusion seat 15. Springs are fixed between the two ends of the extrusion sheet 20 and the extrusion seat 15. During operation, through the setting of the extrusion sheet 20, the extrusion sheet 20 is a thin sheet of metal material. During the process of the extrusion strip 22 being pushed outward, the extrusion sheet 20 will also change its own curvature. Since the metal material has toughness, the curvature of the surface of the extrusion sheet 20 will be greater than the curvature of the extrusion strip 22. By controlling the protruding distance of the extrusion strip 22, the curvature of the extrusion sheet 20 can be controlled, thereby more accurately controlling the extrusion curvature required for extruding different window frames 4 to be bent, thereby improving the bending quality and accuracy.

[0031] A vertical electric slide rail 18 is provided on the top of the processing table 1, a connecting platform 23 is fixedly connected to the top of the extrusion seat 15, the connecting platform 23 is connected to the moving end of the electric slide rail 18, a plurality of hydraulic rods 17 for driving the electric slide rail 18 to translate are installed on the outer side of the electric slide rail 18, and the hydraulic rods 17 are fixedly connected to the processing table 1; During operation, the lifting and lowering of the extrusion seat 15 is controlled by the electric slide rail 18, and the translation of the electric slide rail 18 and the extrusion seat 15 is controlled by the hydraulic rod 17, so that the extrusion seat 15 can be controlled to accurately extrude the top surface of the window frame 4 to be bent from any position, ensuring the smooth progress of the bending work.

[0032] During operation, the window frame 4 to be bent, which is much longer than the required length of the bending frame 5, is placed on the processing table 1 through the setting of the guide frame and the processing table 1. The placement method is: the head of the window frame 4 to be bent is passed through multiple binding wheels 3 from one end in turn, and one end of the window frame 4 to be bent is moved to the top of the bending arm 12 by the driving of the binding wheel 3. At this time, the extrusion seat 15 moves to the top of the window frame 4 to be bent to compress and fix the window frame 4 to be bent, and then the bending arm 12 rotates, synchronously driving the window frame 4 to be bent at the upper part of the bending arm 12 to be bent, and then the window frame 4 to be bent continues to move forward, and the bending arm 12 bends again. The extrusion seat 15 is fixed at each bending, and the extrusion seat 15 moves away when the window frame 4 to be bent moves; after four bendings, a rectangular bending frame 5 can be produced, and then the circular saw 13 rotates and moves upward to The bent window frame 4 and the finished bent frame 5 are cut and divided. During the bending process of the bent frame 5, it will automatically sleeve on the outer side of the guide frame 6. After the separation is completed, due to the low height of the free end of the guide frame 6, the bent frame 5 will slide outward under the action of gravity for transfer. Through this arrangement, not only the function of automatically transferring the finished bent frame 5 is realized, but also the shape and gravity of the guide frame 6 can be used to transfer the finished bent frame 5 without using any electrical equipment, which not only allows the device to work continuously, but also facilitates the storage of finished products and the subsequent large-scale transfer work; and the setting of the extra-long window frame 4 to be bent can also increase the feeding interval of the device, reduce the frequency of feeding, and the device can automatically cut the window frame 4 to be bent of the required length, reducing the pretreatment process of the bent window frame 4; The upper and lower electric wheels 1 fix the window frame 4 to be bent, and the window frame 4 to be bent can be driven to move horizontally with the driving of the electric wheels. When the device is working, the protective cover 2 is closed to reduce the influence of the external environment. When encountering window frames 4 to be bent with different thicknesses, the electric wheel 1 can be slid upward to adjust the distance between the two electric wheels 1, so that the window frame 4 to be bent can be stably clamped without damaging the window frame 4 to be bent. The bending frame 5 sleeved on the guide frame 6 will eventually slide to one side of the support column 7 under the action of gravity. Since the bending frame 5 will partially rebound after bending, the bending frame 5 will not touch the window frame 4 to be bent, ensuring the normal bending process. At the same time, when the bending frame 5 is on the guide frame 6, due to the gap at the bottom of the bending frame 5, when it is necessary to conduct random inspection or take samples, a single bending frame 5 can be directly taken away. When the guide frame 6 is full of finished products, the end of the guide frame 6 can be disconnected from the processing table 1, and the entire guide frame 6 can be transferred to complete the batch transportation of finished products. In order to facilitate the batch transportation of finished products, when the guide frame 6 near the support column 7 is full of bending frames 5, the electromagnetic lock is opened to separate the two sections of the guide frame 6. After separation, the servo motor drives the support column 7 to rotate, and then the guide frame 6 is rotated to make the end of the guide frame 6 face downward, so that the bending frames 5 hung on the guide frame 6 are downwardly moved, so that the finished products are collected in batches. When the collection is completed, the guide frame 6 is returned to its position, and the two sections of the guide frame 6 are connected under the drive of the electromagnetic lock to continue the work of receiving the finished products. After the support column 7 drives a section of the guide frame 6 to rotate, the end of the guide frame 6 is directed toward the receiving rod 10, and then the guide frame 6 rotates downward to align with the end of the receiving rod 10, and the end of the guide frame 6 overlaps the top of the receiving rod 10. At this time, the end of the guide frame 6 faces downward, and the finished product on the guide frame 6 will slide onto the receiving rod 10 under the action of gravity. Then the guide frame 6 returns to its original position and the two sections are fixed, and the mobile platform 8 can be transferred outward under the setting of the universal wheel. Through this setting, the finished products on the guide frame 6 can be transferred quickly, which greatly reduces the downtime transfer time of the device and ensures production efficiency. The setting of the counterweight block 9 is to ensure the center of gravity position of the mobile platform 8 and reduce the risk of tipping during the transfer process; the method for observing the number of finished products on the guide frame 6 can be directly observed by an optical camera, and when the number is reached, the finished product transfer is directly performed; When the finished product transfer is completed, the electric winding roller is started to reel in the steel cable 24, and the end of the guide frame 6 is lifted upward. When the two sections of the guide frame 6 are fixed, the lower pressing roller 25 is sunk by the electric telescopic rod 26, so that the steel cable 24 is attached to the surface of the guide frame 6, so that the force balance can still be maintained. This operation is to ensure that the supporting force of the finished product is provided by the guide frame 6 instead of the steel cable 24, and the way in which the steel cable 24 lifts the height of the end of the guide frame 6 is a labor-saving lever, which ensures the stable rotation process of the guide frame 6; The bending arm 12 is driven to rotate by the reduction motor 16, and the bending arm 12 drives the upper window frame 4 to be bent to bend, thereby realizing the work of processing the bending frame 5; When the window frame 4 to be bent is being bent, the extrusion seat 15 moves to the top of the window frame 4 to be bent and squeezes the bending part. The arc setting is to ensure that the corner of the bending frame 5 after bending will not break due to the excessive corner. At the same time, the bending arc required by the window frames 4 to be bent of different thicknesses needs to be appropriately changed. The window frame 4 to be bent with a larger thickness is directly pressed by the extrusion seat 15. The window frame 4 to be bent with a smaller thickness is pressed outward by the electric telescopic rod 19, so that the extrusion strip 22 with a smaller surface area fits, thereby adapting to the processing of the window frames 4 to be bent of two thicknesses. The surface of the extrusion seat 15 is provided with a groove for accommodating the extrusion strip 22. By setting the extrusion sheet 20, the extrusion sheet 20 is a thin sheet of metal material. When the extrusion strip 22 is pushed outward, the extrusion sheet 20 will also change its curvature. Since the metal material has toughness, the curvature of the surface of the extrusion sheet 20 will be greater than the curvature of the extrusion strip 22. By controlling the protruding distance of the extrusion strip 22, the curvature of the extrusion sheet 20 can be controlled, so that the extrusion curvature required when extruding different window frames 4 to be bent can be more accurately controlled, thereby improving the bending quality and accuracy; The lifting and lowering of the extrusion seat 15 is controlled by the electric slide rail 18, and the translation of the electric slide rail 18 and the extrusion seat 15 is controlled by the hydraulic rod 17, so that the extrusion seat 15 can be controlled to accurately extrude the top surface of the window frame 4 to be bent from any position, ensuring the smooth progress of the bending work.
