Description

Technical Field

[0001] The invention relates to the technical field of hollow glass, and in particular to a bending method of a sealing type spacer strip used for hollow glass. Background Art

[0002] The sealed spacers used for insulating glass are filled with granular desiccant inside. In order to ensure the dryness inside the insulating glass, the amount of desiccant inside the sealed spacers is relatively high. It can occupy about 50% to 90% of the internal space of the spacer. However, since the spacers are filled with desiccant, the desiccant will hinder the bending of the spacers, resulting in more cracks, tears, irregularities or wrinkles at the bending parts of the spacers. The above situation will seriously affect the performance of the spacers after being installed in the insulating glass, and greatly reduce the aesthetics of the spacers, affecting the user experience. Summary of the invention

[0003] In order to overcome the above defects of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a bending method for a sealed spacer bar for insulating glass, which can solve the negative impact of the internal desiccant on the bending of the spacer bar when the spacer bar is bent.

[0004] The specific technical solution of the embodiment of the present invention is:

[0005] A method for bending a sealing type spacer for insulating glass, the method comprising the following steps:

[0006] The spacer is placed in a horizontal direction with its front side facing downward along the gravity direction, and the desiccant in the spacer is evenly distributed in the horizontal direction along the inside of the spacer;

[0007] A first bending distance is measured from the B end to the A end of the spacer bar to determine a first bending point on the front side of the spacer bar, abutting the abutting end of the first bending tool against the position of the first bending point on the front side of the spacer bar, and abutting the first rotating member and the second rotating member of the second bending tool against the back side of the spacer bar, wherein the rotating shaft connecting the first rotating member and the second rotating member of the second bending tool is located on the side of the first bending point close to the B end in the horizontal direction, and the second rotating member is close to the B end of the spacer bar relative to the first rotating member;

[0008] The abutting end of the first bending tool is relatively moved in a first direction by a first preset distance, so that the front side of the first bending point of the spacer bar is recessed inwardly, and at the same time, the second rotating member is rotated in the bending direction by a first preset angle to make the B end of the spacer bar droop, so that the desiccant on the side of the first bending point of the spacer bar close to the B end falls to the B end of the spacer bar, so that there is no desiccant at the first bending point in the spacer bar;

[0009] Continue to move the abutting end of the first bending tool relative to the first direction by a second preset distance so that the front side of the first bending point of the spacer bar continues to be recessed inward. At the same time, the second rotating member rotates in the bending direction by a second preset angle to bend the spacer bar to a target angle.

[0010] Preferably, the step of placing the spacer bar in a horizontal direction with its front side facing downward along the direction of gravity, and making the desiccant in the spacer bar uniformly distributed in the horizontal direction along the interior of the spacer bar comprises:

[0011] Place the spacer completely vertically so that the desiccant inside the spacer flows to the bottom;

[0012] The spacer is rotated from the vertical direction to the horizontal direction to form the repose angle of the desiccant, so that the desiccant can freely flow inside the spacer and be evenly distributed along the opposite ends of the spacer. In this process, the front side of the spacer faces downward and the back side of the spacer faces upward;

[0013] After the desiccant freely flows and is evenly distributed inside the spacer bar along the opposite ends of the spacer bar, the spacer bar is rotated to be placed in a horizontal direction.

[0014] Preferably, the desiccant is spherical, and the angle of repose is in a range of 18 to 40 degrees.

[0015] Preferably, the distance between the rotating shaft connecting the first rotating member and the second rotating member of the second bending tool and the abutting end of the first bending tool in the horizontal direction is 5mm to 50mm, and the thickness between the front and back sides of the spacer strip is between 6.5mm±0.15mm.

[0016] Preferably, the first preset angle is greater than the repose angle of the desiccant.

[0017] Preferably, the target angle is equal to the sum of the second preset angle and the first preset angle, and the target angle is 90 degrees.

[0018] Preferably, the angle between the first direction and the horizontal direction is between 45±25 degrees.

[0019] Preferably, the spacer strips are made of metal material.

[0020] The technical solution of the present invention has the following significant beneficial effects:

[0021] The bending method of the sealed spacer used for hollow glass in the present application first treats the desiccant inside the spacer to be evenly distributed in the horizontal direction and the front side is downward along the gravity direction, and then the initial fold is performed at the position of the first bending point, so that the front side at the first bending point is concave inward, and the B end of the spacer droops by a first preset angle, so that the desiccant on the side of the first bending point of the spacer close to the B end falls to the B end of the spacer, thereby removing the desiccant at the first bending point. Then, at the first bending point, the abutting end of the first bending tool is relatively moved toward the first direction by a second preset distance, so that the front side at the first bending point of the spacer continues to be concave inward, and the spacer is completely bent to the target angle. In this process, since there is no desiccant between the front and back sides of the spacer at the first bending point, when the spacer is bent at a large angle later, there will be no desiccant to hinder the large-angle bending of the spacer, and it will not cause cracks, tears, irregularities or wrinkles in the bending part of the spacer. The entire bending method can make the bending part of the spacer strip more beautiful, greatly reducing the possible cracking, tearing, irregularity or wrinkles.

[0036] In order to solve the negative impact of the internal desiccant 14 on the bending of the spacer bar 1 when the spacer bar 1 is bent, a bending method for a sealed spacer bar for insulating glass is proposed in the present application. Figure 1 FIG. 1 is a flow chart of the steps of a method for bending a sealing spacer for insulating glass in an embodiment of the present invention. Figure 1 As shown, the bending method of the sealing spacer for insulating glass may include the following steps:

[0037] S101: Place the spacer bar 1 in a horizontal direction with its front side 11 facing downward along the gravity direction, and make the desiccant 14 in the spacer bar 1 evenly distributed in the horizontal direction along the inside of the spacer bar 1.

[0038] In the above steps, the specific structure of the sealing spacer strip 1 for insulating glass can be as follows: Figure 2 Schematic diagram of the structure of the sealing spacer used for insulating glass in an embodiment of the present invention. Figure 3 for Figure 2 The cross-sectional view at EE is as follows: Figure 2 and Figure 3As shown, the spacer bar 1 has two opposite ends, namely end A and end B, both ends of the spacer bar 1 are sealed, and a desiccant 14 is loaded inside the spacer bar 1. The spacer bar 1 has a relative front side 11, a back side 12, and two side walls 13, wherein the so-called front side 11 is the side facing the inner side of the hollow glass cavity after the spacer bar 1 is bent into a frame. The so-called side wall 13 is the side that is against the glass when the spacer bar 1 is combined with the glass. The back side 12 is the side opposite to the front side 11 of the spacer bar 1. The spacer bar 1 is made of metal material, so it has ductility and can be bent.

[0039] Place the spacer bar 1 in the horizontal direction with its front side 11 facing downward along the direction of gravity. When the front side 11 of the spacer bar 1 faces downward along the direction of gravity, the desiccant 14 in the spacer bar 1 needs to be evenly distributed in the horizontal direction along the inside of the spacer bar 1. In this way, when the spacer bar 1 is subsequently bent, it can avoid excessive desiccant 14 in local positions of the spacer bar 1, which may cause the spacer bar 1 to break, tear, become irregular or have many wrinkles when being bent.

[0040] Furthermore, in order to achieve a better uniform distribution of the desiccant 14 in the spacer bar 1 in the horizontal direction along the interior of the spacer bar 1, the following steps may be specifically adopted:

[0041] S201: Place the spacer bar 1 completely vertically so that the desiccant 14 inside the spacer bar 1 flows to the bottom.

[0042] In this step, Figure 4 FIG. 1 is a schematic diagram of a sealing spacer for insulating glass in an embodiment of the present invention when placed completely vertically. Figure 4 As shown, the spacer bar 1 can be placed completely vertically, such as with the B end facing forward, so that all the desiccant 14 inside the spacer bar 1 flows to the B end.

[0043] S202: Rotate the spacer bar 1 from the vertical direction to the horizontal direction to form a repose angle of the desiccant 14, so that the desiccant 14 can flow freely inside the spacer bar 1 and be evenly distributed along the opposite ends of the spacer bar 1. During this process, the front side 11 of the spacer bar 1 faces downward, and the back side 12 of the spacer bar 1 faces upward.

[0044] In this step, the spacer bar 1 is rotated from the vertical direction to the horizontal direction to form a repose angle Y of the desiccant 14. Figure 5 Schematic diagram of the internal desiccant when the sealed spacer used for insulating glass in the embodiment of the present invention is rotated to form a repose angle of the desiccant with the horizontal direction, as shown in FIG. Figure 5As shown, during this process, the spacer bar 1 rotates from the vertical direction to the front side 11, until the A end of the spacer bar 1 is downward and the B end is upward, and finally to the angle of repose of the desiccant 14 with the horizontal direction. During this process, the desiccant 14 flows freely until it is evenly distributed inside the spacer bar 1 along the opposite ends of the spacer bar 1, and the desiccant 14 can be prohibited from continuing to flow downward. During the above rotation process, the desiccant 14 will definitely flow to the lower end until it is evenly distributed along the front side 11. Compared with other vibration methods, since the initial distribution of the desiccant 14 in the inner spacer bar is uncertain, the movement force and amplitude of the desiccant 14 after reciprocating vibration are also uncertain, so its final distribution is also uncertain. Since the distribution of the desiccant 14 inside the inner spacer bar cannot be detected, it may cause the sealed spacer bar 1 to have more desiccant 14 at one end and less desiccant 14 at the other end. Furthermore, the desiccant 14 may be spherical, and correspondingly, the repose angle of the spherical desiccant 14 generally ranges from 18 degrees to 40 degrees.

[0045] S203: After the desiccant 14 flows freely and is evenly distributed inside the spacer bar 1 along the two opposite ends of the spacer bar 1, the spacer bar 1 is rotated to be placed in a horizontal direction.

[0046] In the above steps, Figure 6 FIG. 1 is a schematic diagram of a sealing spacer for insulating glass in an embodiment of the present invention before being bent, cooperating with a first bending tool and a second bending tool 3, as shown in FIG. Figure 6 As shown, after the desiccant 14 flows freely and is evenly distributed inside the spacer bar 1 along the opposite ends of the spacer bar 1, the spacer bar 1 is rotated toward the front side 11, that is, the A end of the spacer bar 1 is raised, and the B end of the spacer bar 1 is lowered, and finally the spacer bar 1 is rotated to be placed in a horizontal direction.

[0047] S102: Measure the first bending distance X from the B end to the A end of the spacer bar 1 to determine the first bending point on the front side 11 of the spacer bar 1, press the abutting end 21 of the first bending tool 2 against the first bending point on the front side 11 of the spacer bar 1, press the first rotating member 31 and the second rotating member 32 of the second bending tool 3 against the back side 12 of the spacer bar 1, the rotating shaft connecting the first rotating member 31 and the second rotating member 32 of the second bending tool 3 is located on the side of the first bending point close to the B end in the horizontal direction, and the second rotating member 32 is close to the B end of the spacer bar 1 relative to the first rotating member 31.

[0048] In this step, since the entire spacer bar 1 needs to be bent multiple times, Figure 6As shown, the first bending distance is measured from the B end to the A end of the spacer bar 1 to determine the first bending point on the front side 11 of the spacer bar 1. The first bending point is the position closest to the B end that needs to be bent. The abutting end 21 of the first bending tool 2 is pressed against the position of the first bending point on the front side 11 of the spacer bar 1. The outer contour of the cross section of the abutting end 21 of the first bending tool 2 can be in the shape of an arc, so that the bending part of the front side 11 of the spacer bar 1 is not prone to cracking, tearing, irregularity, etc. when bending, so that the bending part is finally bent through an arc gradient. The first rotating member 31 and the second rotating member 32 of the second bending tool 3 are pressed against the back side 12 of the spacer bar 1. The side of the first rotating member 31 and the second rotating member 32 close to the back side 12 is completely flat. The opposite ends of the first rotating member 31 and the second rotating member 32 are hinged together to achieve rotation. The rotating shaft connecting the first rotating member 31 and the second rotating member 32 of the second bending tool 3 is located on the side of the first bending point close to the B end in the horizontal direction, and the second rotating member 32 is close to the B end of the spacer bar 1 relative to the first rotating member 31.

[0049] Furthermore, due to the current national standard, the thickness between the front side 11 and the back side 12 of the spacer bar 1 needs to be between 6.5mm±0.15mm. Therefore, correspondingly, the distance between the rotating shaft connecting the first rotating member 31 and the second rotating member 32 of the second bending tool 3 and the abutting end 21 of the first bending tool 2 in the horizontal direction is between 5mm and 50mm. It can be specifically determined according to the radius of the bending of the spacer bar 1 at the first bending point. The larger the bending radius, the greater the distance between the rotating shaft connecting the first rotating member 31 and the second rotating member 32 of the second bending tool 3 and the abutting end 21 of the first bending tool 2 in the horizontal direction. Of course, the larger the bending radius, the larger the radius size of the arc-shaped outer contour of the cross-section of the abutting end 21 of the first bending tool 2.

[0050] In order to ensure the bending effect and avoid adverse consequences such as rupture and tearing of the bending part of the spacer strip 1 after bending, the rotating shaft connecting the first rotating part 31 and the second rotating part 32 of the second bending tool 3 needs to be at least 5mm away from the contact end 21 of the first bending tool 2 in the horizontal direction.

[0051] S103: Move the abutting end 21 of the first bending tool 2 in a first direction by a first preset distance so that the front side 11 at the first bending point of the spacer bar 1 is recessed inward. At the same time, the second rotating member 32 is rotated in the bending direction by a first preset angle to make the B end of the spacer bar 1 droop, so that the desiccant 14 on the side of the first bending point of the spacer bar 1 close to the B end falls toward the B end of the spacer bar 1, so that there is no desiccant at the first bending point in the spacer bar 1.

[0052] In this step, Figure 7FIG. 1 is a schematic diagram of a sealing spacer for insulating glass after being bent at a first preset angle in an embodiment of the present invention. Figure 7 As shown, the abutting end 21 of the first bending tool 2 is relatively moved toward the first direction by a first preset distance, so that the front side 11 at the first bending point of the spacer bar 1 is recessed inward, thereby facilitating the B end of the spacer bar 1 to bend toward the side of the front side 11 more easily. Furthermore, the angle between the first direction and the horizontal direction can be preferably selected between 45±25 degrees, so as to ensure the balance of the inward recess of the front side 11 at the first bending point of the spacer bar 1 on both sides, and avoid the recess being too biased to one side, resulting in more wrinkles or irregularities on that side, while the corresponding side will extend too much, which is easy to cause tearing. As a more preferred embodiment, the angle between the first direction and the horizontal direction can be controlled between 45±5 degrees.

[0053] At the same time, Figure 7 As shown, the second rotating member 32 is pressed against the back side 12 of the spacer bar 1 to rotate in the bending direction by a first preset angle to make the B end of the spacer bar 1 droop, so that the desiccant 14 on the side of the first bending point of the spacer bar 1 close to the B end falls toward the B end of the spacer bar 1, so that there is no desiccant at the first bending point in the spacer bar 1. The first preset angle needs to be greater than the repose angle of the desiccant 14, so that the desiccant 14 can flow toward the B end. As a matter of course. The first preset angle is less than the target angle for the final bending of the spacer bar 1. Furthermore, in order to accelerate the desiccant 14 to fall into the B end of the spacer bar 1, the spacer bar 1 can be appropriately vibrated during the bending process to improve the bending efficiency.

[0054] In this step, since the spacer bar 1 is initially folded, the first preset distance can be controlled between 10% and 30% of the thickness between the front side 11 and the back side 12 of the spacer bar 1. It is not necessary to move the abutting end 21 of the first bending tool 2 too much toward the first direction at one time, otherwise it is easy to cause tearing or irregularity at the concave portion of the front side 11 of the spacer bar 1.

[0055] Through the above process, the desiccant 14 inside the spacer bar 1 at the first bending point can flow to the B end, so that there is no desiccant 14 between the front side 11 and the back side 12 inside the spacer bar 1 at the first bending point. When the spacer bar 1 is bent at a large angle later, there will be no desiccant 14 to hinder the large-angle bending of the spacer bar 1, and the bending part of the spacer bar 1 will not be cracked, torn, irregular or wrinkled.

[0056] S104: Continue to move the abutting end 21 of the first bending tool 2 relative to the first direction by a second preset distance so that the front side 11 at the first bending point of the spacer bar 1 continues to be recessed inward. At the same time, the second rotating member 32 rotates in the bending direction by a second preset angle so that the spacer bar 1 is bent to a target angle.

[0057] In this step, the desiccant 14 on the side of the first bending point of the spacer bar 1 close to the B end all falls into the B end of the spacer bar 1, and there is basically no desiccant 14 between the front side 11 and the back side 12 at the first bending point inside the spacer bar 1. Figure 8 FIG. 1 is a schematic diagram of a sealing spacer for insulating glass after being bent at a second preset angle according to an embodiment of the present invention. Figure 8 As shown, the abutting end 21 of the first bending tool 2 is continuously moved toward the first direction by a second preset distance, so that the front surface 11 at the first bending point of the spacer bar 1 continues to be recessed inward. The sum of the second preset distance plus the first preset distance can be controlled to be 40%-80% of the thickness between the front surface 11 and the back surface 12 of the spacer bar 1, thereby ensuring the bending effect and preventing the front surface 11 of the spacer bar 1 from being torn due to excessive recessing.

[0058] At the same time, Figure 8 As shown, the second rotating member 32 is further rotated in the bending direction by a second preset angle to bend the spacer bar 1 to a target angle. For example, if a general insulating glass is rectangular, the target angle is equal to the sum of the second preset angle and the first preset angle, and the target angle is 90 degrees. Of course, in other feasible embodiments, the target angle may also be other angles, and generally the target angle needs to be greater than the repose angle of the desiccant 14. If the target angle is too small, the spacer bar 1 may be bent directly without using the bending method of the sealed spacer bar for insulating glass in the present application.

[0059] In this step, since there is no desiccant 14 between the front side 11 and the back side 12 at the first bending point inside the spacer bar 1, when the spacer bar 1 is bent at a large angle, there is no desiccant 14 to hinder the large-angle bending of the spacer bar 1. After the spacer bar 1 is completely bent to the target angle, the entire bending portion can be made more beautiful, greatly reducing the possible cracking, tearing, irregularity or more wrinkles.

[0060] After that, if the spacer bar 1 needs to be bent multiple times, then measure the second bending distance from the B end to the A end of the spacer bar 1 to determine the second bending point on the front side 11 of the spacer bar 1, the second bending point is farther away from the B end relative to the first bending point, repeat the above steps S102 to S104, and by determining the bending points in sequence from the B end to the A end for bending, it can be ensured that the spacer bars 1 between adjacent bending points, the spacer bars 1 near the B end and the spacer bars 1 near the A end all have the desiccant 14 relatively evenly, even if the bending degree of the bending point is large and the desiccant 14 cannot pass through the bending point, the spacer bar 1 will not partially lack the desiccant 14.

[0061] The bending method of the sealed spacer for insulating glass in the present application first processes the desiccant 14 inside the spacer 1 to be evenly distributed in the horizontal direction and the front side 11 is downward along the gravity direction, and then an initial fold is performed at the position of the first bending point, so that the front side 11 at the first bending point is concave inward, and the B end of the spacer 1 droops at a first preset angle, so that the desiccant 14 on the side of the first bending point of the spacer 1 close to the B end falls toward the B end of the spacer 1, thereby removing the desiccant 14 at the first bending point. Then, at the first bending point, the abutting end 21 of the first bending tool 2 is relatively moved toward the first direction by a second preset distance, so that the front face 11 at the first bending point of the spacer bar 1 continues to be recessed inward, and the spacer bar 1 is completely bent to the target angle. In this process, since there is no desiccant 14 between the front face 11 and the back face 12 at the first bending point inside the spacer bar 1, when the spacer bar 1 is bent at a large angle later, there will be no desiccant 14 to hinder the large-angle bending of the spacer bar 1, and it will not cause the spacer bar 1 to break, tear, be irregular or have many wrinkles at the bending part. The entire bending method can make the bending part of the spacer bar 1 more beautiful, greatly reducing the possible phenomenon of breakage, tearing, irregularity or many wrinkles.
