Description

Technical Field

[0001] This utility model relates to the field of door and window manufacturing, and in particular to a back gauge mechanism for a hydraulic bending machine used in door and window manufacturing. Background Technology

[0002] Doors and windows are an important part of the building envelope, serving functions such as lighting, ventilation, sound insulation, heat preservation, and security. Modern doors and windows are mainly made of materials such as aluminum alloy, PVC, and thermally broken aluminum. Among them, aluminum alloy doors and windows have become the mainstream choice due to their high strength, corrosion resistance, and high plasticity. Their core structure includes components such as window frames, window sashes, and glass strips, which need to be formed into specific angles (such as right angles or irregular contours) through precision bending processes to ensure sealing and structural stability.

[0003] The back gauge mechanism is the core positioning system of a bending machine. Chinese patent with publication number CN217018306U discloses a back gauge mechanism for a servo bending machine. By moving the back gauge mechanism to a suitable position, a first electric push rod pushes the upper gauge seat to move and a second electric push rod pushes the lower gauge seat to move, so that the stop balls installed on both the upper and lower gauge seats are in close contact with the surface of the profile, so that the upper and lower gauge seats can simultaneously position the profile at different positions.

[0004] In the above solution, the profile is positioned by having two stop rollers closely attached to the surface of the profile. However, the profiles required in door and window manufacturing are generally plate structures of varying thicknesses, and the plate is a complete flat surface before the first bend. At this time, there is no suitable contact point between the plate and the rollers. At the same time, since some plates have large gaps, the distance between the two rollers is fixed, making it difficult for the two rollers to simultaneously contact the plate surface. This results in one end of the plate being unstable during bending, making it difficult to adapt and position according to the gaps in the plate. Therefore, a back stop mechanism for a hydraulic bending machine for door and window manufacturing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a back gauge mechanism for a hydraulic bending machine for door and window manufacturing, so as to solve the problem mentioned in the background art that one end of the plate is unstable when bending the plate and it is difficult to adapt and position it according to the gap of the plate. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A back gauge mechanism for a hydraulic bending machine used in door and window manufacturing includes a hydraulic bending machine body. The mechanism is characterized by: a fixed plate on one side of the hydraulic bending machine body; a sheet metal, two back gauge components, and a limiting plate disposed between the two fixed plates; each back gauge component includes an upper positioning mechanism and a lower positioning mechanism; a first driving mechanism driving the upper positioning mechanism to move longitudinally in a horizontal plane, and a second driving mechanism driving the back gauge component to move laterally in a horizontal plane, are disposed below the lower positioning mechanism; a baffle plate is installed inside the upper positioning mechanism; the contact end between the baffle plate and the sheet metal is a plane; and a third driving mechanism driving the baffle plate to move up and down is disposed on one side of the upper positioning mechanism.

[0008] Preferably, the upper positioning mechanism includes an upper positioning plate, the lower part of which is mounted on a third slide rail via a slider. One end of the upper positioning plate is provided with a connecting plate, and a top plate is provided above the upper positioning plate. The upper positioning plate and the top plate are connected by a support plate. A through groove is provided in the middle of the support plate. A second lead screw and a guide post are respectively provided on both sides of the support plate. One end of the baffle plate is threadedly connected to the second lead screw, and the other end of the baffle plate passes through the through groove and is sleeved on the guide post.

[0009] Preferably, the third drive mechanism includes a second motor, a drive wheel, and a driven wheel. The second motor is installed below the top plate, and the drive wheel and driven wheel are located above the top plate. The drive wheel is connected to the shaft of the second motor, and the drive wheel and driven wheel are connected by a belt. The driven wheel is connected to the upper shaft of the second lead screw.

[0010] Preferably, the upper and lower sides of the limiting plate are respectively provided with a second slide rail and a rack in the horizontal direction, the side of the limiting plate is provided with a first slide rail in the horizontal direction, the lower positioning mechanism includes a lower positioning plate, one end of the lower positioning plate is mounted on the second slide rail by a slider, the other end of the lower positioning plate is provided with a side plate, a transmission plate is provided below the lower positioning plate, and the side of the transmission plate is mounted on the first slide rail by a slider.

[0011] Preferably, the second drive mechanism includes a gear and a third motor. The third motor is mounted on the side of the transmission plate and is connected to the gear shaft. The gear meshes with the rack.

[0012] Preferably, the first drive mechanism includes a first lead screw and a first motor. The first motor is mounted on the side plate. One end of the first lead screw is connected to the shaft of the first motor. The other end of the first lead screw passes through the side plate and the connecting plate in sequence and is connected to the transmission plate bearing. The connecting plate is threadedly adapted to the first lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features two rear gauge components mounted at the rear of the hydraulic bending machine body. Gauge plates are installed on these components. When bending a sheet metal using the hydraulic bending machine body, the lateral position of the rear gauge components is first adjusted by a third motor to match the distance between the two gauge plates to the width of the sheet metal. Then, the height of the gauge plates is adjusted by a second motor, and finally, the distance between the gauge plates and the end points of the sheet metal is adjusted by a first motor. This ensures that both gauge plates are flush with the flat end of the sheet metal, thereby restricting the position of the sheet metal and preventing deviation of the bending position during subsequent bending, thus improving bending accuracy. Furthermore, since the position of the gauge plates in both rear gauge components can be adjusted independently, the gauge plates can be flush with any notched end of the sheet metal, preventing tilting at one end and improving applicability.

[0022] Please see Figure 1-3In this utility model, a back gauge mechanism for a hydraulic bending machine used in door and window manufacturing includes a hydraulic bending machine body 1. A fixing plate 101 is provided on one side of the hydraulic bending machine body 1. A plate 2, two back gauge components 3, and a limiting plate 4 are provided between the two fixing plates 101. The back gauge component 3 includes an upper positioning plate 6 and a lower positioning plate 5. The limiting plate 4 is an L-shaped structure composed of a narrow plate and a wide plate. A first slide rail 401 is provided on the side of the narrow plate. A second slide rail 402 and a rack 403 are provided on the upper and lower sides of the wide plate, respectively. A third slide rail 501 is provided on the upper part of the lower positioning plate 5 and is arranged longitudinally in the horizontal plane. A first lead screw 503 and a first motor 504 are provided below the lower positioning plate 5. The first lead screw 503 is parallel to the third slide rail 501. A gear 7 and a third motor 701 are provided below the first lead screw 503. A second motor 606, a driving wheel 607, and a driven wheel 608 are provided above the upper positioning plate 6.

[0023] The upper positioning plate 6 is mounted on the third slide rail 501 via a slider. A connecting plate 601 is provided at one end of the upper positioning plate 6, and a top plate 605 is provided above the upper positioning plate 6. The upper positioning plate 6 and the top plate 605 are connected by a support plate 604. A through groove is provided in the middle of the support plate 604. A vertically arranged second lead screw 602 and a guide post 603 are respectively provided on both sides of the support plate 604. One end of the baffle plate 8 is threadedly connected to the second lead screw 602, and the other end of the baffle plate 8 passes through the through groove and is sleeved on the guide post 603. The contact end between the baffle plate 8 and the plate 2 is a plane.

[0024] One end of the lower positioning plate 5 is mounted on the second slide rail 402 via a slider, and the other end of the lower positioning plate 5 is provided with a side plate 502. A transmission plate 505 is provided below the lower positioning plate 5, and the side of the transmission plate 505 is mounted on the first slide rail 401 via a slider.

[0025] Example 1: Please refer to Figure 1-3 In this embodiment of the present invention, a back gauge mechanism of a hydraulic bending machine for manufacturing doors and windows includes a first motor 504 mounted on a side plate 502, one end of a first lead screw 503 connected to the shaft of the first motor 504, and the other end of the first lead screw 503 passing through the side plate 502 and the connecting plate 601 in sequence, and being connected to the transmission plate 505 by a bearing. The connecting plate 601 is threadedly fitted to the first lead screw 503. After the first motor 504 is started, it drives the first lead screw 503 to rotate. The first lead screw 503 then drives the connecting plate 601, the upper positioning plate 6, and the baffle plate 8 to move longitudinally along the third slide rail 501 in sequence, thereby adjusting the position between the baffle plate 8 and the plate 2.

[0026] The second motor 606 is installed below the top plate 605, and the driving wheel 607 and the driven wheel 608 are located above the top plate 605. The driving wheel 607 is connected to the shaft of the second motor 606, and the driving wheel 607 and the driven wheel 608 are connected by a belt. The driven wheel 608 is connected to the upper shaft of the second lead screw 602. After the second motor 606 starts, it drives the driving wheel 607, the driven wheel 608 and the second lead screw 602 to rotate in sequence. The second lead screw 602 drives the baffle plate 8 to move up and down along the guide post 603.

[0027] The third motor 701 is installed on the side of the transmission plate 505. The third motor 701 is connected to the shaft of the gear 7. The gear 7 meshes with the rack 403. After the third motor 701 is started, it drives the gear 7 to rotate, so that the gear 7 moves along the transmission plate 505 along the first slide rail 401. The transmission plate 505 then drives the lower positioning plate 5 to move along the second slide rail 402. The first slide rail 401 and the second slide rail 402 are parallel, so that the entire back gauge assembly 3 can move laterally, thereby adjusting the lateral position of the baffle plate 8.

[0028] Before bending the sheet 2, first adjust the lateral position of the two baffle plates 8, then adjust the height of the two baffle plates 8, and finally adjust the distance between the two baffle plates 8 and the sheet 2, so that the two baffle plates 8 are in contact with the flat end of the sheet 2. This restricts the position of the sheet 2 and prevents the bending position on the sheet 2 from shifting during subsequent bending, thus improving the bending accuracy. At the same time, since the positions of the two back baffle components 3 can be adjusted independently, the baffle plates 8 can be in contact with any notched end on the sheet 2, which can prevent the notched end of the sheet 2 from being unable to be positioned and causing tilting, thereby improving applicability and further improving the accuracy of subsequent bending.

[0029] The working principle of this utility model is as follows: Before bending the sheet 2, the positions of the baffle plates 8 are adjusted by two independent back baffle components 3, so that the two baffle plates 8 can be in contact with the end positions of the sheet 2, avoiding the situation of unbalanced positioning at both ends of the sheet 2 due to the limitations of the sheet 2 structure, thereby improving applicability and improving the accuracy of subsequent bending.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
