Description

Technical Field

[0001] The present invention relates to the technical field of building materials production and processing equipment, and particularly to a bending device for metal door and window processing. Background Art

[0002] The bending process in metal door and window processing is a process of bending metal profiles into a predetermined shape and angle by means of mechanical force, thermal force, etc. This process is particularly important in the manufacture of aluminum alloy doors and windows because it can meet the diverse requirements of window design, improve design freedom, enhance structural stability, and improve sealing performance. In order to improve the stability of bending operations, bending equipment is often used to improve processing efficiency.

[0003] The prior art has the following deficiencies: In the "bending device for door and window processing" with the publication number CN116900113B in the prior art, "it includes a processing table, a bending member, a driver, a positioning unit, a flipping unit, and an extrusion unit; a first slideway is provided in the middle of the processing table, the bending member can slide in the first slideway, and the driver is arranged on the processing table and connected to the bending member".

[0004] The above structure reciprocates along the length direction of the processing table driven by the driver. When the bending member moves, it pushes the door and window plate into contact with the extrusion unit and abuts against it. After being pressed by the bending member, the extrusion unit is bent into a V shape, so that the bending member and the extrusion unit are completely attached to the bent door and window plate, avoiding the area where the bending member and the extrusion unit do not contact the door and window plate, which affects the bending quality of the door and window plate. However, this structure only improves the bending process. After bending, it is still necessary to manually take out the bent material. Moreover, since the bending operation requires the bending structure to be close to the outer side of the material, it is difficult to take out the bent material from the narrow structure. In addition, the bending structure of this device adopts a traditional fixed design, resulting in the size of the bent material needing to completely conform to the design size of the device and being unable to be adjusted adaptively, thereby reducing the versatility of the device. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a bending device for metal door and window processing, which solves the problems of manual taking out of bent materials and poor versatility caused by non-adjustable bending spacing existing nowadays.

[0006] To achieve the above object, the present invention provides the following technical solution: A bending device for metal door and window processing, including a workbench, a control panel, a first motor, and a driving gear. The control panel is arranged on the outer side end of the workbench, the first motor is arranged inside the workbench, and the driving gear is arranged above the first motor.

[0007] A main shaft positioning gear is provided at the side end of the driving gear. A self - disengaging linkage frame is provided at the upper end of the workbench. A ball connection block is arranged inside the self - disengaging linkage frame. A second motor is provided at the side end of the self - disengaging linkage frame. An end support frame is provided at the bottom of the second motor. A guide wheel is provided at the bottom end of the end support frame.

[0008] The main shaft positioning gear further includes a fixed - end bending roller, a connecting shaft, and a bearing sleeve. The fixed - end bending roller is movably connected to the top of the connecting shaft. The connecting shaft passes through the middle of the main shaft positioning gear. The bearing sleeve is sleeved around the bottom periphery of the connecting shaft and is movably connected thereto.

[0009] In some embodiments, the workbench further includes an adjustment bracket and a limit chute. The adjustment bracket is movably connected to the side end of the workbench. The limit chute is opened at the top of the workbench and is embedded by the guide wheel.

[0010] In some embodiments, the connecting shaft also passes through the side wall of the self - disengaging linkage frame. The tooth grooves of the main shaft positioning gear and the driving gear are meshed with each other.

[0011] In some embodiments, the self - disengaging linkage frame further includes a threaded rod, a linkage gear, a support shaft, and a swing arm. The threaded rod is movably connected between the second motor and the side wall of the self - disengaging linkage frame. The tooth groove of the linkage gear is meshed with the thread on the periphery of the threaded rod.

[0012] In some embodiments, the support shaft passes through the middle of the linkage gear and is movably connected inside the self - disengaging linkage frame. The swing arm is sleeved on one end of the support shaft passing through the side wall of the self - disengaging linkage frame.

[0013] In some embodiments, the ball connection block further includes a limit block and a movable - end bending roller. The limit blocks are fixedly connected to both sides of the ball connection block. The movable - end bending roller is fixedly connected to the top of the ball connection block. And a columnar structure is provided between the ball connection block and the movable - end bending roller to establish a connection.

[0014] In some embodiments, the ball connection block is sleeved around the periphery of the threaded rod, and a ball structure is arranged inside it to establish a movable connection relationship with the threaded rod.

[0015] In some embodiments, a strip - shaped groove structure extending inwards is opened at the front side wall position of the self - disengaging linkage frame, and this groove structure is penetrated by the limit block. And a groove structure penetrating up and down is opened at the position where the top of the self - disengaging linkage frame is penetrated by the connecting column below the movable - end bending roller.

[0016] Compared with the prior art, the present invention provides a bending device for processing metal doors and windows:

[0017] A bending device for processing metal doors and windows. By setting a main shaft positioning gear, a self - detaching linkage frame, a threaded rod, a ball connection block, a swing arm, a support shaft, a linkage gear and a guide wheel, when the device is in use, the operator controls the first motor and the second motor through the control panel, inserts the raw material of the door and window to be bent between the fixed - end bending roller and the movable - end bending roller. The first motor starts and drives the main shaft positioning gear to rotate through the driving gear. When the main shaft positioning gear rotates, it drives the self - detaching linkage frame to rotate through the support of the connecting shaft and the bearing sleeve. After the self - detaching linkage frame drives the movable - end bending roller to rotate 90°, it stops. After the movable - end bending roller bends the processing material, the second motor starts, and at the same time drives the threaded rod to rotate. When the threaded rod rotates, it causes the ball connection block to drive the movable - end bending roller to translate towards the second - motor side. While the threaded rod rotates, the linkage gear is driven synchronously, and the swing arm is driven to lift through the support shaft. When the swing arm lifts, the bent material is lifted out from the widened gap between the fixed - end bending roller and the movable - end bending roller;

[0018] Through the above settings and processes, the device has the following beneficial effects:

[0019] 1. Through the cooperation of the threaded rod, the support shaft and the swing arm, the bent processing material can be quickly removed from the workbench, thus saving the demoulding time of the bent material, improving the automation level and streamlining the bending steps;

[0020] 2. Through the cooperation of the ball connection block, the threaded rod and the limit block, when the threaded rod is driven after the material is bent, the distance between the fixed - end bending roller and the movable - end bending roller can be enlarged by moving the ball connection block. By this method, not only can the demoulding smoothness of the bent material be further improved, but also the versatility of the device can be improved by adjusting the bending distance.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In this embodiment: A bending device for processing metal doors and windows includes a workbench 1, a control panel 2, a first motor 3, and a driving gear 4. The control panel 2 is arranged on the outer side end of the workbench 1, the first motor 3 is arranged inside the workbench 1, and the driving gear 4 is arranged above the first motor 3.

[0033] A main shaft positioning gear 5 is provided at the side end of the driving gear 4, a self - disengaging linkage frame 6 is provided at the upper end of the workbench 1, a ball connection block 7 is arranged inside the self - disengaging linkage frame 6, a second motor 8 is provided at the side end of the self - disengaging linkage frame 6, an end support frame 9 is arranged at the bottom of the second motor 8, and a guide wheel 10 is arranged at the bottom end of the end support frame 9.

[0034] The main shaft positioning gear 5 further includes a fixed - end bending roller 501, a connecting shaft 502, and a bearing sleeve 503. The fixed - end bending roller 501 is movably connected to the top of the connecting shaft 502. The connecting shaft 502 penetrates through the middle of the main shaft positioning gear 5. The bearing sleeve 503 is sleeved around the bottom periphery of the connecting shaft 502 and is movably connected thereto.

[0035] In this embodiment, the workbench 1 further includes an adjusting bracket 101 and a limit chute 102. The adjusting bracket 101 is movably connected to the side end of the workbench 1. The limit chute 102 is opened at the top of the workbench 1 and is embedded by the guide wheel 10. The connecting shaft 502 also penetrates through the side wall of the self - disengaging linkage frame 6. The main shaft positioning gear 5 meshes with the tooth grooves of the driving gear 4.

[0036] Specifically, as Figure 1 and Figure 4 shown, through the connection of the end support frame 9, the guide wheel 10 supports the self - disengaging linkage frame 6 from the rear end, reduces the bottom friction when it rotates 90°, and limits it at the same time.

[0037] In this embodiment, the self - disengaging linkage frame 6 further includes a threaded rod 601, a linkage gear 602, a support shaft 603, and a swing arm 604. The threaded rod 601 is movably connected between the second motor 8 and the side wall of the self - disengaging linkage frame 6. The tooth groove of the linkage gear 602 meshes with the external thread of the threaded rod 601. The support shaft 603 penetrates through the middle of the linkage gear 602 and is movably connected to the inside of the self - disengaging linkage frame 6. The swing arm 604 is sleeved on one end of the support shaft 603 passing through the side wall of the self - disengaging linkage frame 6.

[0038] Specifically, as Figure 2 and Figure 3 and Figure 6 shown, when the threaded rod 601 is driven, the ball connection block 7 and the linkage gear 602 move simultaneously. The ball connection block 7 drives the movable - end bending roller 702 to translate, while the linkage gear 602 drives the swing arm 604 to swing through the support shaft 603.

[0039] In this embodiment, the ball connection block 7 further includes a limit block 701 and a movable end bending roller 702. The limit block 701 is fixedly connected to both sides of the ball connection block 7, and the movable end bending roller 702 is fixedly connected to the top of the ball connection block 7. A columnar structure is provided between the ball connection block 7 and the movable end bending roller 702 to establish a connection. The ball connection block 7 is sleeved around the outer periphery of the threaded rod 601, and a ball structure is provided inside it to establish a movable connection relationship with the threaded rod 601.

[0040] Specifically, as Figure 5 and Figure 7 shown, when the ball connection block 7 moves, the limit block 701 on the side end that penetrates through the side wall of the self-disengaging linkage frame 6 ensures the stability of the movement of the ball connection block 7, and the maximum movement range is limited according to the strip-shaped groove opened on the side wall of the self-disengaging linkage frame 6.

[0041] In this embodiment, a strip-shaped groove structure extending inwards is opened at the front side wall position of the self-disengaging linkage frame 6, and this groove structure is penetrated by the limit block 701. A through-up-and-down groove structure is opened at the position where the top of the self-disengaging linkage frame 6 is penetrated by the connecting column below the movable end bending roller 702.

[0042] The working principle and usage process of the present invention: When the device is in use, the operator controls the first motor 3 and the second motor 8 through the control panel 2, inserts the raw material of the door and window to be bent between the fixed end bending roller 501 and the movable end bending roller 702. The first motor 3 is started and drives the main shaft positioning gear 5 to rotate through the driving gear 4. When the main shaft positioning gear 5 rotates, it drives the self-disengaging linkage frame 6 to rotate through the support of the connecting shaft 502 and the bearing sleeve 503. After the self-disengaging linkage frame 6 drives the movable end bending roller 702 to rotate 90°, it stops. After the movable end bending roller 702 bends the processing material, the second motor 8 is started, and at the same time, the threaded rod 601 is driven to rotate. When the threaded rod 601 rotates, it causes the ball connection block 7 to drive the movable end bending roller 702 to translate towards the second motor 8 side. While the threaded rod 601 rotates, the linkage gear 602 is driven synchronously, and the swing arm 604 is driven to lift through the support shaft 603. When the swing arm 604 lifts, the bent material is lifted out from the widened gap between the fixed end bending roller 501 and the movable end bending roller 702.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
