A forming device for a glass tempering equipment with reversible bidirectional arc change

Abstract

A forming device for a glass tempering equipment with bidirectional variable arc, including a plurality of sequentially arranged variable arc units. When the connecting rod rotates, it drives the up-and-down movement of the sliding pin shaft, enabling the bottom sides of two adjacent variable arc units to move away from or close to each other, so as to respectively perform forward variable arc rotation and reverse variable arc rotation. The angles of the forward variable arc rotation and the reverse variable arc rotation are respectively related to the distances that the sliding pin shaft can move downward and upward from the position in the flattened state. When the equipment is in the flattened state, by driving the arc-adjusting gear to rotate, the distances between the limiting shoulder and the threaded sleeve, and between the limiting nut and the bottom plate or the adjusting sleeve can be changed, thereby realizing the adjustment of the variable arc curvature and enabling variable diameter with unequal curvatures. After the variable arc, the variable arc curvature can also be finely adjusted manually. Through mechanical limiting, the accuracy of the variable arc can be guaranteed, and there will be no wear after long-term use, and the target curvature radius can be accurately generated.

Description

Technical Field

[0001] The present invention relates to the field of glass tempering equipment, and particularly to a forming device for a glass tempering equipment with bidirectional variable arc in both forward and reverse directions. Background Art

[0002] Tempered glass belongs to prestressed glass and has the advantages of high hardness, good load-bearing capacity, strong wind resistance, excellent cold and heat resistance, and impact resistance. The forming device of the glass tempering equipment has a variable arc function. However, the existing glass tempering equipment can usually only perform single forward variable arc or single reverse variable arc. Therefore, when it is necessary to produce positive-bent glass and negative-bent glass simultaneously, both a forward variable arc device and a reverse variable arc device are required, which not only increases the equipment procurement cost but also additionally occupies the production site. When the existing glass tempering equipment performs variable arc, the rotation angles between adjacent variable arc units are all the same fixed value. Therefore, the rotation angles of forward variable arc or reverse variable arc are fixed, resulting in an unadjustable equal curvature and equal radius of the variable arc of the glass tempering equipment, making it difficult to achieve unequal curvature and variable diameter, and also impossible to adjust the variable arc curvature. In the existing glass tempering equipment, adjacent variable arc units are rotated through mutually meshing gears, that is, the rotation angle of the variable arc unit is restricted by the position of the gear after it stops rotating. Therefore, the clearance of the gear fit will cause inaccurate arc, and the wear of the gear after long-term use will also reduce the variable arc accuracy. Summary of the Invention

[0003] The purpose of the present invention is to provide a forming device for a glass tempering equipment with bidirectional variable arc in both forward and reverse directions, so as to achieve accurate, adjustable, and variable curvature bidirectional variable arc in both forward and reverse directions.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: a forming device for a glass tempering equipment with bidirectional variable arc in both forward and reverse directions, including a plurality of variable arc units arranged in sequence. The top sides of adjacent two variable arc units are rotatably connected through a connecting shaft, and all the connecting shafts are parallel to each other to facilitate the variable arc rotation of the plurality of variable arc units in cooperation. The variable arc unit includes a bottom plate and two relatively arranged side plates. The bottom plate is respectively connected to the bottom sides of the two side plates. The connecting shaft is inserted into the top sides of the two side plates at the same time. A support seat is also installed between the two side plates. A gear shaft is rotatably installed on the support seat through a bearing. The axis of the gear shaft is perpendicular to the axis of the connecting shaft, and the axes of the two connecting shafts located on the top side of the same variable arc unit are symmetrically arranged about the axis of the gear shaft of this variable arc unit;

[0005] Chutes are respectively provided on two side plates. The length direction of the chutes is parallel to the axis of the gear shaft. A sliding pin shaft and a positioning pin shaft are provided between the two side plates. The axes of the sliding pin shaft and the positioning pin shaft are both parallel to the axis of the connecting shaft, and the axes of the sliding pin shaft and the positioning pin shaft are both perpendicular to and intersect with the axis of the gear shaft. The positioning pin shaft is located between the chute and the bottom plate. The two ends of the positioning pin shaft are respectively connected to the two side plates. The two ends of the sliding pin shaft are respectively inserted into the chutes of the two side plates, so that the sliding pin shaft can move along the length direction of the chute;

[0006] Link rods are provided between adjacent arc-changing units. One end of a link rod is rotatably connected to the positioning pin shaft, and the other end of the link rod is rotatably connected to the sliding pin shaft of the adjacent arc-changing unit. By rotating the link rod and driving the sliding pin shaft to move downward along the chute, the bottom sides of two adjacent arc-changing units can be separated from each other to facilitate forward arc-changing rotation; by rotating the link rod and driving the sliding pin shaft to move upward along the chute, the bottom sides of two adjacent arc-changing units can be close to each other to facilitate reverse arc-changing rotation;

[0007] An arc-adjusting gear is installed at the top end of the gear shaft. The arc-adjusting gear is located above the support seat. A central rotating shaft is provided below the support seat. The axis of the central rotating shaft coincides with the axis of the gear shaft. The central rotating shaft sequentially penetrates through the sliding pin shaft, the positioning pin shaft and the bottom plate. The bottom end of the gear shaft is inserted into the axial central hole of the central rotating shaft. The gear shaft and the central rotating shaft are connected by a key or a spline, so that the gear shaft and the central rotating shaft can rotate synchronously, and the central rotating shaft can move axially relative to the gear shaft. The external thread on the upper half of the central rotating shaft is in mating connection with the threaded hole of the sliding pin shaft, so that the central rotating shaft and the sliding pin shaft can move axially synchronously, and the gear shaft can drive the central rotating shaft to move relative to the sliding pin shaft;

[0008] A threaded sleeve and an adjusting sleeve are sleeved on the lower half of the central rotating shaft. The external thread of the threaded sleeve is in mating connection with the threaded hole of the bottom plate. The adjusting sleeve is rotatably installed on the bottom plate and is positioned axially relative to the bottom plate. The adjusting sleeve and the threaded sleeve are connected by a key or a spline, so that the adjusting sleeve can drive the threaded sleeve to move axially;

[0009] A limiting shoulder is provided in the middle of the central rotating shaft. The top end of the threaded sleeve can block the limiting shoulder moving downward along with the sliding pin shaft and the central rotating shaft, so as to limit the rotation angle of forward arc-changing. A limiting nut is screwed at the bottom end of the central rotating shaft. The bottom end of the bottom plate or the adjusting sleeve can block the limiting nut moving upward along with the sliding pin shaft and the central rotating shaft, so as to limit the rotation angle of reverse arc-changing.

[0010] Preferably, the side plates are T-shaped flat plates, and the bottom plate is fixedly connected to the bottom sides of the two side plates.

[0011] Preferably, the central rotating shaft is a hollow shaft, and a spline matching the bottom end of the gear shaft is provided at the top end of the inner hole of the hollow shaft.

[0012] Preferably, support bolts are respectively inserted through the two side plates, and the support bolts are screwed into the threaded holes of the support seats.

[0013] Preferably, the axes of the threaded sleeve and the adjusting sleeve both coincide with the axis of the central rotating shaft. The top end of the adjusting sleeve is inserted into the axial through hole of the threaded sleeve, and a spline matching the bottom end of the threaded sleeve is provided at the top end of the adjusting sleeve.

[0014] According to the above technical solution, the beneficial effects of the present invention are as follows:

[0015] 1. When the connecting rod rotates in the present invention, it drives the up-and-down movement of the sliding pin shaft, enabling the bottom sides of two adjacent arc-changing units to move away from or close to each other, so that forward arc-changing rotation and reverse arc-changing rotation can be respectively carried out, and there is no need to separately prepare forward arc-changing equipment and reverse arc-changing equipment, reducing the equipment procurement cost and the production site occupied.

[0016] 2. The angles of forward arc-changing rotation and reverse arc-changing rotation are respectively related to the distances that the sliding pin shaft can move downward and upward from the position in the flattened state. Specifically, it is the downward movement distance of the limit shaft shoulder starting from the flattened position and the upward movement distance of the limit nut starting from the flattened position. When the equipment is in the flattened state, by driving the arc-adjusting gear to rotate, the central rotating shaft can rotate relative to the sliding pin shaft, and through thread cooperation, the central rotating shaft can perform axial movement relative to the sliding pin shaft, so as to change the distance between the limit shaft shoulder and the threaded sleeve and the distance between the limit nut and the bottom plate or the adjusting sleeve, and thus the arc-changing rotation angle of adjacent arc-changing units can be changed, thereby realizing the adjustment of the arc-changing curvature. Moreover, since each arc-changing unit can be adjusted independently, the arc-changing rotation angles of multiple arc-changing units can be different, and unequal-curvature variable diameter can be achieved.

[0017] 3. After arc-changing in the present invention, the threaded sleeve can be driven to move by manually rotating the adjusting sleeve, or the limit nut can be manually rotated to move axially, so that the arc-changing curvature can be finely adjusted manually. Moreover, the fine adjustments of forward and reverse arc-changing are independent of each other, and there is no need to manually adjust repeatedly when switching between forward and reverse.

[0018] 4. In the present invention, the rotation of the arc-changing unit is no longer achieved through meshing gears, and the rotation angle of the arc-changing unit is no longer limited by the position after the gears stop rotating. Instead, mechanical limitation is performed on the movement of the limiting shoulder and the limiting nut, so that the arc accuracy will not be affected by the clearance of gear fit. Moreover, the mechanical limitation method will not wear out after long-term use, and will not reduce the arc-changing accuracy after long-term use. It can ensure the arc-changing accuracy, accurately generate the target curvature radius, and greatly improve the forming accuracy of tempered glass. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0028] Referring to the accompanying drawings, the detailed implementation is as follows:

[0029] As Figure 1As shown in the figure, a forming device for a glass tempering equipment with bidirectional arc variation includes seven arc variation units arranged in sequence. The top sides of two adjacent arc variation units are rotatably connected through a connecting shaft 2, and all the connecting shafts 2 are parallel to each other. Multiple arc variation units can cooperate to perform arc variation rotation. Figure 5 That is, seven arc variation units cooperate to rotate to the positive arc variation state. Figure 7 That is, nine arc variation units cooperate to rotate to the reverse arc variation state.

[0030] As Figures 1-4 shown, the arc variation unit includes a bottom plate 8 and two side plates 1 arranged oppositely. The side plates 1 are T-shaped flat plates. The bottom plate 8 is fixedly connected to the bottom sides of the two side plates 1. The connecting shaft 2 is inserted into the top sides of the two side plates 1 at the same time. A support seat 11 is also provided between the two side plates 1. Support bolts 3 are respectively inserted through the two side plates 1, and the support bolts 3 are screwed into the threaded holes of the support seat 11. A gear shaft 12 is rotatably installed on the support seat 11 through a pair of bearings. The axis of the gear shaft 12 is perpendicular to the axis of the connecting shaft 2, and the axes of the two connecting shafts 2 located on the top side of the same arc variation unit are symmetrically arranged with respect to the axis of the gear shaft 12 of this arc variation unit.

[0031] As Figures 1-4 shown, chutes 4 are respectively opened on the two side plates 1. The length direction of the chutes 4 is parallel to the axis of the gear shaft 12. A sliding pin shaft 5 and a positioning pin shaft 6 are provided between the two side plates 1. The axes of the sliding pin shaft 5 and the positioning pin shaft 6 are both parallel to the axis of the connecting shaft 2, and the axes of the sliding pin shaft 5 and the positioning pin shaft 6 are both perpendicular to and intersect with the axis of the gear shaft 12. The positioning pin shaft 6 is located between the chute 4 and the bottom plate 8. The two ends of the positioning pin shaft 6 are respectively connected to the two side plates 1. The two ends of the sliding pin shaft 5 are respectively inserted into the chutes 4 of the two side plates 1. The end of the sliding pin shaft 5 matches the width of the chute 4, so that the sliding pin shaft 5 can move along the length direction of the chute 4.

[0032] As Figure 1 shown, a connecting rod 7 is provided between two adjacent arc variation units. One end of the connecting rod 7 is rotatably connected to the positioning pin shaft 6, and the other end of the connecting rod 7 is rotatably connected to the sliding pin shaft 5 of the adjacent arc variation unit. As Figure 2 shown, connecting rods 7 are respectively provided at the two axial ends of the positioning pin shaft 6 and the sliding pin shaft 5. The axis of the connecting rod 7 is perpendicular to the axes of the positioning pin shaft 6 and the sliding pin shaft 5. When performing arc variation, by rotating the connecting rod 7 and driving the sliding pin shaft 5 to move downward along the chute 4, the bottom sides of two adjacent arc variation units can be separated from each other. At this time, two adjacent arc variation units will perform positive arc variation rotation. On the contrary, by rotating the connecting rod 7 and driving the sliding pin shaft 5 to move upward along the chute 4, the bottom sides of two adjacent arc variation units can be close to each other. At this time, two adjacent arc variation units will perform reverse arc variation rotation.

[0033] AsFigure 2 , 3 As shown in 3 , an arc-adjusting gear 13 is installed at the top end of the gear shaft 12. The arc-adjusting gear 13 is located above the support base 11. A central rotating shaft 9 is provided below the support base 11. The axis of the central rotating shaft 9 coincides with the axis of the gear shaft 12. The central rotating shaft 9 sequentially passes through the sliding pin shaft 5, the positioning pin shaft 6, and the bottom plate 8. The central rotating shaft 9 is a hollow shaft. At the top end of the inner hole of the hollow shaft, there is a spline that matches the bottom end of the gear shaft 12. The bottom end of the gear shaft 12 is inserted into the axial center hole of the central rotating shaft 9.

[0034] Since the gear shaft 12 and the central rotating shaft 9 are connected by a spline, the gear shaft 12 and the central rotating shaft 9 can rotate synchronously, and the central rotating shaft 9 can move axially relative to the gear shaft 12. The external thread on the upper half of the central rotating shaft 9 is in mating connection with the threaded hole of the sliding pin shaft 5. Therefore, the central rotating shaft 9 and the sliding pin shaft 5 can move axially synchronously. And when the sliding pin shaft 5 and the connecting rod 7 are fixed and the gear shaft 12 rotates, it can drive the central rotating shaft 9 to move up and down relative to the sliding pin shaft 5.

[0035] As Figure 4 shown, a threaded sleeve 15 and an adjusting sleeve 16 are sleeved on the lower half of the central rotating shaft 9. The axes of the threaded sleeve 15 and the adjusting sleeve 16 both coincide with the axis of the central rotating shaft 9. The external thread of the threaded sleeve 15 is in mating connection with the threaded hole of the bottom plate 8. The adjusting sleeve 16 is rotatably installed on the bottom plate 8 and is axially positioned relative to the bottom plate 8. The top end of the adjusting sleeve 16 is inserted into the axial through hole of the threaded sleeve 15. At the top end of the adjusting sleeve 16, there is a spline that matches the bottom end of the threaded sleeve 15. Since the adjusting sleeve 16 and the threaded sleeve 15 are connected by a spline, the adjusting sleeve 16 and the threaded sleeve 15 can rotate synchronously and drive the threaded sleeve 15 to move axially.

[0036] As Figures 2-4 shown, a limiting shoulder 14 is provided in the middle of the central rotating shaft 9. The top end of the threaded sleeve 15 can block the limiting shoulder 14 that moves downward along with the sliding pin shaft 5 and the central rotating shaft 9. A limiting nut 10 is screwed at the bottom end of the central rotating shaft 9. The bottom end of the adjusting sleeve 16 can block the limiting nut 10 that moves upward along with the sliding pin shaft 5 and the central rotating shaft 9. In this embodiment, two limiting nuts 10 are arranged in pairs to prevent the limiting nut 10 from loosening on the central rotating shaft 9.

[0037] The angles of forward arc-changing rotation and reverse arc-changing rotation are respectively related to the distances that the sliding pin shaft 5 can move downward and upward from the position in the flattened state. Specifically, it is the downward movement distance H1 of the limiting shoulder 14 starting from the flattened position, that is, the sliding pin shaft 5 and the central rotating shaft 9 move downward from the Figure 2 position to Figure 6The distance required for the position of H1 = 0, and the upward movement distance H2 of the limit nut 10 starting from the flattened position, that is, the sliding pin shaft 5 and the central rotating shaft 9 move upward from the Figure 2 position to Figure 8 the distance required for the position of H2 = 0.

[0038] When the device is maintained in the Figure 1 flattened state, by driving the arc-adjusting gear 13 to rotate, the central rotating shaft 9 can be rotated relative to the sliding pin shaft 5, and through the thread fit, the central rotating shaft 9 can perform an axial movement relative to the sliding pin shaft 5, so that the sizes of H1 and H2 can be changed, and the arc-changing rotation angle of adjacent arc-changing units can also be changed, thereby realizing the adjustment of the arc-changing curvature. Moreover, since each arc-changing unit can be adjusted independently, the arc-changing rotation angles of multiple arc-changing units can be different, and unequal-curvature variable diameter can be realized.

[0039] After arc-changing, the adjusting sleeve 16 can be further rotated manually to drive the threaded sleeve 15 to move and finely adjust H1, thereby finely adjusting the positive arc-changing curvature by manual adjustment. It can also be further rotated manually to move the limit nut 10 axially and finely adjust H2, thereby finely adjusting the reverse arc-changing curvature by manual adjustment. Moreover, the fine adjustments of the positive and reverse arc-changes are independent of each other. When switching between the positive and reverse directions, there is no need to manually adjust repeatedly. After adjustment, by mechanically limiting the limit shoulder 14 and the limit nut 10, the accuracy of arc-changing can be guaranteed, and there will be no wear after long-term use, and the target curvature radius can be accurately generated.
