[0037] 200. Spacer bar. Detailed Implementation
[0038] In related technologies, aluminum spacers are key components of insulated glass units, serving to support and separate the glass panes, ensuring the stability and airtightness of the insulated structure. To accommodate glass of different sizes and shapes, spacers need to be bent into specific curvatures to meet the design requirements of round or irregularly shaped insulated glass units. However, existing bending devices suffer from poor adaptability, making it difficult to accommodate spacers of different specifications, thus affecting the production efficiency of insulated glass units; furthermore, the bending accuracy is relatively low.
[0039] Therefore, this application provides a spacer bar bending and forming device to solve the problems in the related technology.
[0040] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0041] Combination Figures 1 to 6 As shown, this application embodiment provides a spacer bar bending forming device, including: a pressure roller 101, a lifting mechanism 102, a support assembly 103, and a first driving mechanism 104; the pressure roller 101 has a plurality of first grooves 106 spaced apart along its own axial direction in the circumferential direction; the lifting mechanism 102 is used to drive the pressure roller 101 to move along a first direction; the first driving mechanism 104 is used to drive the pressure roller 101 to rotate; the support assembly 103 includes two support wheels 105 spaced apart along a second direction, the first direction and the second direction are not parallel, and the support wheels 105 have a plurality of second grooves 107 spaced apart along their own axial direction.
[0042] This application utilizes the cooperation of multiple first grooves 106 and multiple second grooves 107 to accommodate spacer bars 200 of different widths and thicknesses. The lifting mechanism 102 adjusts the position of the pressure roller 101 along a first direction, causing the spacer bars 200 to form different bending radii, thereby accommodating multiple specifications of spacer bars 200, reducing equipment change frequency, and flexibly adapting to diverse processing needs, thus improving production efficiency. The first drive mechanism 104 drives the pressure roller 101 to rotate, ensuring a continuous and consistent bending process for the spacer bars 200, improving curvature accuracy. Furthermore, since there are multiple first grooves 106 and multiple second grooves 107, multiple spacer bars 200 with the same bending radius can be added simultaneously, further improving processing efficiency.
[0043] In some embodiments, the first direction and the second direction are perpendicular to each other; the widths of the plurality of first grooves 106 are different, and the widths of the plurality of second grooves 107 are different, so that spacers 200 of different widths can be applied.
[0044] In some embodiments, the spacer 200 can be made of aluminum; the spacer 200 is used in the manufacture of insulated glass. In use, the first direction can be parallel to the vertical direction. The first groove 106 is annular and extends circumferentially around the pressure roller 101. The groove width direction of the first groove 106 is parallel to the axial direction of the pressure roller 101; the groove width of the plurality of first grooves 106 can gradually decrease along the axial direction of the pressure roller 101. The second groove 107 is annular and extends circumferentially around the support roller 105. The groove width direction of the second groove 107 is parallel to the axial direction of the support roller 105; the groove width of the plurality of second grooves 107 can gradually decrease along the axial direction of the support roller 105. The axial direction of the pressure roller 101 can be parallel to the axial direction of the support roller 105. The direction in which the groove width of the plurality of first grooves 106 decreases is the same as the direction in which the groove width of the plurality of second grooves 107 decreases, thus allowing for the application of spacer 200s of different widths.
[0045] In some embodiments, the spacer bar bending and forming device can adapt to spacer bars 200 with a width of 10mm-20mm and a thickness of 5mm-10mm. The groove width of the first groove 106 and the groove width of the second groove 107 are both adapted to the thickness of the spacer bar 200. For example, there are three first grooves 106, with groove widths of 6mm, 8mm, and 11mm respectively. There are also three second grooves 107, with groove widths of 6mm, 8mm, and 11mm respectively. The depth of the first groove 106 can be 4mm-6mm, specifically 4mm, 5mm, or 6mm; and the depth of the second groove 107 can also be 4mm-6mm, specifically 4mm, 5mm, or 6mm. It should be noted that the number of first grooves 106 and the number of second grooves 107 can also be two or four.
[0046] Combination Figures 1 to 6 As shown, in some embodiments, the spacer bar bending forming device further includes a bracket 108, and the lifting mechanism 102 includes a first lead screw 109 and a guide block 110. A pressure roller 101 is mounted on the guide block 110, and the first lead screw 109 is threadedly connected to the guide block 110. The guide block 110 is slidably mounted on the bracket 108, and the first direction is parallel to the axial direction of the first lead screw 109. The first lead screw 109 allows for precise control of the movement displacement of the guide block 110. For example, the bracket 108 has a plate-like structure; the first lead screw 109 can be mounted on the bracket 108 via a bearing seat, and the first lead screw 109 can rotate around its own axis, but it cannot move along its own axial direction. The guide block 110 has a threaded hole, and the first lead screw 109 is threadedly driven by the threaded hole on the guide block 110, so that the rotation of the first lead screw 109 itself allows the guide block 110 to move along the axial direction of the first lead screw 109. Understandably, the support 108 can also be made of other structures, such as tubular structures made of stainless steel or aluminum alloy.
[0047] Combination Figures 1 to 6 As shown, in some embodiments, the bracket 108 may have a mounting groove 112, and the guide block 110 is disposed in the mounting groove 112. For example, the guide block 110 may have a slot 113, and the bracket 108 extends into the slot 113 to realize that the guide block 110 is slidably disposed on the bracket 108, and the guide block 110 can only move along the axial direction of the first lead screw 109, and will not rotate with the first lead screw 109. The spacer bar bending forming device also includes a second wheel shaft 114, which is fixedly connected to the guide block 110. A first bearing may be sleeved on the second wheel shaft 114, the inner ring of the first bearing is fixedly connected to the second wheel shaft 114, and the outer ring of the first bearing is fixedly connected to the pressure roller 101, so that the pressure roller 101 can rotate around the axis of the second wheel shaft 114.
[0048] It should be noted that in some other possible embodiments, the spacer bar bending forming device may also include a linear slide rail, and the guide block 110 is slidably disposed on the bracket 108 via the linear slide rail, wherein the guide block 110 is fixedly connected to the slider of the linear slide rail, and the guide rail of the linear slide rail is fixed on the bracket 108.
[0049] Combination Figures 1 to 6As shown, in some embodiments, the spacer bar bending and forming device further includes a base 115, and a bracket 108 is fixedly connected to the base 115. This base 115 allows the spacer bar bending and forming device to be fixed to the worktable, thereby ensuring stability during the use of the device. For example, the base 115 can be a plate-like structure, and can be fixed to the worktable by screws or by a clamp. The bracket 108 can be made of steel or aluminum alloy, and the base 115 can be made of cast iron or aluminum alloy.
[0050] Combination Figures 1 to 6 As shown, in some embodiments, the lifting mechanism 102 further includes a handwheel 116, which is fixedly connected to one end of the first lead screw 109. Rotating the handwheel 116 allows the first lead screw 109 to rotate, thereby achieving the lifting movement of the guide block 110. Specifically, the guide block 110 moves along the axial direction of the first lead screw 109, which in turn drives the pressure roller 101 to move along the axial direction of the first lead screw 109, thus adjusting the distance between the axis of the pressure roller 101 and the connecting line between the axes of the two support rollers 105. The handwheel 116 can be made of steel or aluminum alloy.
[0051] Combination Figures 1 to 6 As shown, in some embodiments, the spacer bar bending forming device further includes a first scale 117 and a first pointer 118; the first scale 117 is disposed on the bracket 108, and the first pointer 118 is fixed on the guide block 110. The first pointer 118 is used to indicate the scale on the first scale 117, thereby facilitating the reading of the vertical distance between the center of the pressure roller 101 and the center of the two support rollers 105, thereby reducing manual visual inspection errors, ensuring the bending quality of the spacer bar 200, and improving the quality of the finished insulating glass product; the measuring range of the first scale 117 can be 80mm-300mm, and the graduation value is 1mm. Specifically, the measuring range of the first scale 117 can be 80mm, 100mm, 200mm, or 300mm. The first scale 117 can be a separate structure from the bracket 108. The first scale 117 is fixed to the bracket 108 by screws, riveting or gluing. It is understood that the first scale 117 can also be directly engraved on the bracket 108 by laser processing.
[0052] Combination Figures 1 to 6As shown, in some embodiments, the first driving mechanism 104 includes a hand crank 119, which is fixedly connected to the pressure roller 101 and is used to drive the pressure roller 101 to rotate. The hand crank 119 can be used to rotate the axis of the second wheel shaft 114 of the pressure roller 101. For example, the hand crank 119 can also be called a crank handle. When the spacer strip 200 is bent into a circle, the pressure roller 101 is located on one side of the spacer strip 200, while the two support wheels 105 are located on the other side of the spacer strip 200. The hand crank 119 continuously drives the pressure roller 101 to rotate, and the two support wheels 105 are linked together through the spacer strip 200. The hand crank 119 can be made of aluminum alloy.
[0053] Combination Figures 1 to 6 As shown, in some embodiments, the spacing between the two support wheels 105 is fixed. Thus, by adjusting only the vertical distance between the center of the pressure wheel 101 and the connecting line between the centers of the two support wheels 105, a spacer strip 200 with the desired bending radius can be obtained. The pressure wheel 101 can be made of polyurethane or a rubber-coated steel wheel; the support wheels 105 can be made of polyurethane or a rubber-coated steel wheel.
[0054] It is understood that in other embodiments, the spacing between the two support wheels 105 is configured to be adjustable so that the spacer 200 can be bent to the desired bending radius.
[0055] Combination Figure 7 and Figure 8 As shown, in some embodiments, the bracket 108 has a waist-shaped hole 121, and the support assembly 103 also includes a first wheel axle 120. The support wheel 105 is mounted on the first wheel axle 120, and the first wheel axle 120 is fixed in the waist-shaped hole 121. The length direction of the waist-shaped hole 121 is parallel to the second direction. For example, the first wheel axle 120 may have a shoulder, so that after the first wheel axle 120 passes through the waist-shaped hole 121, the shoulder abuts against one side of the bracket 108. The first wheel axle 120 is then threadedly connected to a mounting nut located on the other side of the bracket 108, thereby fixing the first wheel axle 120 to the bracket 108. It is understood that the mounting nut can be a disc nut, which facilitates tightening and loosening. The support wheel 105 can be connected to the first wheel shaft 120 via a second bearing. The inner ring of the second bearing is fixedly connected to the first wheel shaft 120, and the outer ring of the second bearing is fixedly connected to the support wheel 105, thereby enabling the support wheel 105 to rotate relative to the first wheel shaft 120. Since the first wheel shaft 120 is installed in the oblong hole 121, the position of the first wheel shaft 120 along the length of the oblong hole 121 can be adjusted, thereby adjusting the distance between the centers of the two support wheels 105. The length of the oblong hole 121 can be from 90mm to 120mm, specifically 90mm, 100mm, or 120mm.
[0056] Combination Figure 9 and Figure 10 As shown, in some embodiments, the spacer bar bending forming device further includes a spacing adjustment mechanism, which includes a second lead screw 122, two linear slide rails 123, a first nut 124, and a second nut 125. The first nut 124 and the second nut 125 are respectively mounted on the sliders 126 of the two linear slide rails 123. The second lead screw 122 has a first thread and a second thread, the direction of rotation of the first thread being opposite to that of the second thread. The first nut 124 engages with the first thread, and the second nut 125 engages with the second thread. One support wheel 105 is mounted on the first nut 124, and the other support wheel 105 is mounted on the second nut 125. This allows the two support wheels 105 to move simultaneously, that is, to move towards each other or away from each other, so as to reduce or increase the spacing between the centers of the two support wheels 105. For example, the guide rail of the linear slide rail 123 can be fixed to the bracket with screws. The bracket 108 is also provided with an oblong hole 121 so that the first wheel shaft 120 can pass through the oblong hole 121 to be fixedly connected to the slider 126. The second lead screw 122 can be driven by a motor, or it can be fixedly connected to one end of the second lead screw 122 by another handwheel 116, and the second lead screw 122 can be rotated by rotating the handwheel 116. The first nut 124 and the corresponding slider 126 of the linear slide rail 123 can be an integral structure, and the second nut 125 and the corresponding slider 126 of the linear slide rail 123 can be an integral structure. The first wheel shaft 120 of one support wheel 105 is fixedly connected to the first nut 124, and the second wheel shaft 114 of the other support wheel 105 is fixedly connected to the second nut 125. The first wheel shaft 120 passes through the bracket 108, and the first wheel shaft 120 can move together with the slider 126 in the second direction.
[0057] Understandably, when the spacing between the two support wheels 105 is configured to be adjustable, the spacer bar bending forming device may also include a second scale (not shown) and a second pointer (not shown) mounted on the first wheel axle 120 of the support wheel 105; the second scale is parallel to a second direction, the second scale is disposed on the bracket 108, and the second pointer is used to indicate the scale on the second scale, thereby facilitating the reading of the center distance between the wheel centers of the support wheels 105. The second scale may be a separate structure from the bracket 108, and the second scale may be fixed to the bracket 108 by screws, riveting, or adhesive; it is also understood that the second scale may be directly engraved on the bracket 108 by laser processing.
[0058] In this embodiment of the application, the formula for calculating the radius R after the spacer bar is bent into a circle by 200 degrees can be:
[0059]
[0060] See Figure 2 As shown, R represents the radius of the spacer strip 200 after bending, L represents the center distance between the centers of the two support wheels 105, and h represents the perpendicular distance of the line connecting the center of the pressure wheel 101 and the centers of the two support wheels 105. Thus, based on the radius after bending, and after setting the center distance between the centers of the two support wheels 105, the perpendicular distance of the line connecting the center of the pressure wheel 101 and the centers of the two support wheels 105 can be calculated. It should be noted that other formulas can also be used to calculate the radius of the spacer strip 200 after bending; this application does not impose specific limitations.
