By applying the technical scheme of the embodiment, glass is placed at the crossing position of the first slideway 111 and the second slideway 112 and extends to the second slideway 112, the glass is positioned between the first sliding block structure 12 and the second sliding block structure 13, the glass is pushed by the second sliding block structure 13, and the glass is deformed under the action of the first arc-shaped surface 121 and the second arc-shaped surface 131. After the first slider structure 12 and the second slider structure 13 move in place, the third slider structure 14 moves toward the second slider structure 13, and the third curved surface 141 and the second curved surface 131 apply a force to the glass, so that the glass continues to deform. The glass cambered surface manufactured by the hot bending pressing process has higher precision and less appearance pits. The two arc surfaces and the second arc surface form the manufacture of the larger arc surface of the glass. The technical scheme of the embodiment effectively solves the problems that the processed annular glass in the prior art is low in precision and large in appearance pits, and samples with high requirements on precision and appearance cannot reach mass production specifications.

It should be noted that, the center line of the first slideway 111 is parallel to two opposite sides of the substrate structure 11, and is located at a middle position of the two opposite sides, so as to penetrate the entire substrate structure 11; the center line of the second slide way 112 is perpendicular to the center line of the first slide way 111, and the two center lines intersect at a midpoint, and the second slide way 112 intersects with the first slide way 111 throughout the entire substrate structure 11.

It should be noted that, the first arc-shaped surface 121, the second arc-shaped surface 131 and the third arc-shaped surface 141 are all smooth surfaces, so that the surface of the annular glass is smooth after the molding is completed, the precision is high and the pits are few. The first end (the side far away from the second slider structure 13) of the cross section of the second arc-shaped surface 131 along the horizontal direction is a half oval cross section, the second end (the side close to the second slider structure 13) of the cross section of the second arc-shaped surface 131 along the horizontal direction is two curves gradually shrinking towards the major axis of the oval along the direction from the first end to the second end, and the major axis of the oval is on the same straight line with the symmetry axis of the second slider structure 13. The cross section of the first arcuate surface 121 cut in the horizontal plane is a half-ellipse (the ellipse is a circle, but the half-ellipse is a half of the ellipse cut by the minor axis, and the symmetry axis of the half-ellipse is on the same line as the symmetry axis of the first slider structure 12. The first arcuate surface 121 cooperates with a first end of the second arcuate surface 131, and the third arcuate surface 141 cooperates with a second end of the second arcuate surface 131.

As shown in fig. 2 and fig. 4, in the technical solution of the present embodiment, the first slider structures 12 include two, one side of each first slider structure 12 facing away from the first arc-shaped surface 121 is a plane 122, and the planes 122 of the two first slider structures 12 are disposed opposite to each other. The center lines of the two first slide block structures 12 are overlapped with the first slide way 111, the two first slide block structures 12 are acted by external force and move along the first slide way 111 in a mutually approaching mode until the planes 122 of the two first slide block structures 12 are mutually contacted and attached, and the two first slide block structures 12 cannot move continuously to form limit. The structure of the plane 122 is easy to process and is not easy to squeeze and deform. The first slider structure 12 is limited, the position of the first arc-shaped surface 121 is kept unchanged, the heated and softened glass is attached to the first arc-shaped surface 121 to form a required fixed shape, if the limitation is not carried out, the position of the first arc-shaped surface 121 is changed in the attaching process of the glass and the first arc-shaped surface 121, the glass forming process is influenced, the surface quality of the glass is reduced, and the finished product does not meet the requirements.

As shown in fig. 2 and 5, in the technical solution of the present embodiment, the second slider structure 13 includes two first slider structures 12, the second slider structure 13 includes a pressing section 132 and a first force application section 133 that are connected, the first force application section 133 is located on a side of the pressing section 132 away from the first slider structure 12, and the second arc-shaped surface 131 is located on a side of the pressing section 132. The center lines of the two second slide structures 13 are coincident with the center line of the first slide 111, the second slide structures 13 are used for coacting with the first slide structures 12 so as to process two sides of the glass, because the first force application section 133 is connected with the pressing section 132, when an external force is applied to the first force application section 133 at one side far away from the first slide structures 12, the force is transferred to the pressing section 132, the second arc-shaped surface 131 positioned at the side of the pressing section 132 applies pressure to the softened glass, the glass is deformed, and finally one side of the glass is processed into a shape completely fitting the second arc-shaped surface 131. The first force application section 133 is arranged to increase the surface of the second slider structure 13 which can be acted by external force, so as to prevent the second slider structure 13 from being damaged due to overlarge pressure when the external force is applied. The side of the pressing section 132 is a second arc-shaped surface 131, which plays a supporting role on the second arc-shaped surface 131 to prevent the second arc-shaped surface 131 from being damaged when being pressed.

As shown in fig. 5, in the technical solution of the present embodiment, the first force application section 133 has a first inclined surface 1331, the first inclined surface 1331 faces away from the substrate structure 11, and the height of the first inclined surface 1331 gradually decreases from the direction approaching the pressing section 132 to the direction separating from the pressing section 132. An external force is applied to the first inclined surface 1331, and since the first inclined surface 1331 is on the first force application section 133, the first force application section 133 is connected to the pressing section 132, and the external force applied to the first inclined surface 1331 is transmitted to the pressing section, thereby pressing the softened glass. The first inclined surface 1331 is configured to decompose any directional force applied to the first inclined surface 1331 into a vertical directional force and a horizontal directional force, and the horizontal directional force pushes the entire second slider structure 13. Because the direction of the applied force is arbitrary, the operation of staff is more convenient.

As shown in fig. 2 and 6, in the technical solution of the present embodiment, the third slider structure 14 includes two third slider structures 14, and the two third slider structures 14 are respectively located on two sides of the first slider structure 12. The center lines of the two third slide block structures 14 are overlapped with the center line of the second slide rail 112, the third slide block structures 14 are pushed to move along the second slide rail 112 towards the direction close to the first slide block structure 12, and finally the third slide block structures 14 are matched with the first slide block structure 12, so that the processing of the outer surface of the glass is completed together.

As shown in fig. 6, in the technical solution of the present embodiment, each third slider structure 14 includes a second force application section 142, and two third arcuate surfaces 141 of each third slider structure 14 are located at intervals on a side of the second force application section 142 facing the first slider structure 12. The third sliding block structure 14 is pushed to move towards the first sliding block structure 12 on the second slideway 112 by the action of the external force and the second force application section 142, and as the two third arc-shaped surfaces 141 are arranged on one side towards the first sliding block structure 12, the third arc-shaped surfaces 141 are close to the first sliding block structure 12 and finally form a fit with the first sliding block structure 12, and the processing of the outer surface of the glass is completed together. The second force application section 142 is connected with the two third arc-shaped surfaces 141, so that the two third arc-shaped surfaces 141 are guaranteed to bear acting forces in the same direction, and the processed glass is guaranteed to have the same shape.

As shown in fig. 6, in the technical solution of the present embodiment, the distance between the two third arcuate surfaces 141 on the same second force application section 142 is equal to the lengths of the two first slider structures 12 in the direction of the first slideway 111. Each third arc surface 141 protrudes out of the surface of the second force application section 142, four third arc surfaces 141 are arranged on the two second force application sections 142, two grooves with the same length as the first slide block structure 12 in the direction of the first slideway 111 are respectively formed, when the third arc surfaces 141 are completely attached to glass, two sides of the two first slide block structures 12 are respectively contacted with groove bottoms of the grooves on the two third slide block structures 14, thus protruding parts and the first slide block structures 12 form clamping fit, the first slide block structures 12 and the third slide block structures 14 cannot move continuously, the connection between the first arc surfaces 121 and the third arc surfaces 141 is smooth, and the processed glass has a smooth surface.

It should be noted that the first arcuate surfaces 121 have first guide surfaces at both ends, and the first guide surfaces at both ends of the first arcuate surfaces 121 gradually decrease in height from a direction closer to the symmetry axis of the first slider structure 12 to a direction farther from the symmetry axis of the first slider structure 12. The block on the third slider structure 14 forming the third arcuate surface 141 has a second guide surface at an end thereof close to the symmetry axis of the third slider structure 14, the block being in a direction from the first slider structure 12 to the direction away from the first slider structure 12, and the second guide surface at an end portion of the third arcuate surface 141 (referring to the end portion of the block, and the same for convenience of description) is gradually reduced in height in a direction from the symmetry axis of the third slider structure 14 to the direction close to the symmetry axis of the third slider structure 14. The inclination angle of the guide surface of the short-cut first arc-shaped surface 121 is the same as that of the guide surface of the end part of the third arc-shaped surface 141, and when the first arc-shaped surface 121 and the third arc-shaped surface 141 are matched with the second arc-shaped surface 131, the guide inclined surfaces of the end parts of the first arc-shaped surface 121 and the third arc-shaped surface 141 are mutually attached, and the first arc-shaped surface 121 and the third arc-shaped surface 141 form a continuous surface.

As shown in fig. 6, in the technical solution of the present embodiment, each third slider structure 14 further includes two guiding surfaces 143, each guiding surface 143 is located on a side of the third arc-shaped surface 141 away from the middle, and each guiding surface 143 gradually protrudes inward in a direction from the third arc-shaped surface 141 to the direction approaching the third arc-shaped surface 141. When the glass deforms under the extrusion of the first sliding block structure 12 and the second sliding block structure 13, the two sides of the glass move along the direction of the guiding surface 143, the guiding surface 143 plays a guiding role on the side of the glass, the problem that the position of the glass is cheap in the processing process, the bending angles of the glass on the two sides are different, and the subsequent processing is influenced is avoided.

As shown in fig. 6, in the technical solution of the present embodiment, each second force application section 142 has a second inclined plane 1421, and the height of the second inclined plane 1421 gradually decreases from the direction approaching the third arc-shaped surface 141 to the direction separating from the third arc-shaped surface 141. The external force is applied to the second inclined plane 1421, and since the second inclined plane 1421 and the third curved surface 141 are both on the second force applying section 142, the external force applied to the second inclined plane 1421 is transferred to the second force applying section, and the third curved surface 141 presses the glass. The second inclined surface 1421 may be configured to split any force applied to the second inclined surface 1421 into a force in a vertical direction and a force in a horizontal direction, and the force in the horizontal direction pushes the entire third slider structure 14.

The first arc-shaped surfaces 121 on the two first slide block structures 12 are placed in the intersecting area of the first slide ways 111 and the second slide ways 112 in a deviating way, two pieces of glass to be processed are placed in the second slide ways 112, one side surface of the two pieces of glass is attached to the side surface of the second slide ways 112, and the other side surface of the two pieces of glass is attached to the first arc-shaped surfaces 121 of the first slide block structures 12. Two second slider structures 13 are placed in the first slideway 111, and are respectively placed at two sides of an intersection area of the first slideway 111 and the second slideway 112, and the second arc-shaped surfaces 131 of the two second slider structures 13 are attached to glass. Two third slider structures 14 are placed in the second slideway 112, and are respectively placed at two sides of the intersection area of the first slideway 111 and the second slideway 112, and the third arc-shaped surfaces 141 of the two third slider structures 14 are oppositely arranged at the intersection area of the first slideway 111 and the second slideway 112. The glass is heated by an external device, the glass is softened, the two second slide block structures 13 are simultaneously pushed at the same speed along the direction of the first slide rail 111, the two first slide block structures 12 are simultaneously pushed when the glass is deformed, and the two first slide block structures 12 are mutually close. After the glass is deformed to a certain extent, the two third slide block structures 14 are simultaneously pushed at the same speed along the direction of the second slide rail 112, the third arc-shaped surface 141 of the third slide block structure 14 is contacted with the glass, and the glass is continuously deformed. When the two first slider structures 12 are in contact with each other, the two second slider structures 13 are pushed continuously, and when the two second slider structures 13 and the two third slider structures 14 cannot be pushed continuously, the pushing is stopped, at this time, the surface of the glass is completely attached to the surfaces of the first arc-shaped surface 121, the second arc-shaped surface 131 and the third arc-shaped surface 141, the heating is stopped, and the glass is cooled to be shaped. At this time, the inner surfaces of the two glasses are consistent with the second arc-shaped surface 131, the middle part of the outer surface of the glass is consistent with the first arc-shaped surface 121, and the two end parts are consistent with the third arc-shaped surface 141, so that the simultaneous processing of the two glasses is completed.

The number of the through holes 211, the driving inclined surfaces 22 and the driving inclined blocks 23 is 2. When the external equipment is used for applying downward pressure to the second die assembly, the driving inclined blocks are lowered in height along the direction of the through holes 211, and the two second slide block structures 13 are pushed to move towards the direction approaching to the first slide block structures; when the height of the driving bevel block 23 is reduced to a certain degree and the upper surface of the cover plate 21 on the upper surface of the driving bevel block 23 is on the same plane, pressure is applied to the cover plate 21 and the driving bevel block 23 simultaneously, and the pressure applied to the cover plate 21 is transferred to the driving bevel 22 to push the third slide block structure 14 to move towards the direction approaching to the second slide block structure 13.

In practice, firstly, the glass side edge is vertically fixed on the slide chute (the guiding surface 143 of the third slide structure 14), the concave surface (the part of the second slide structure 13) and the convex surface forming device (the first slide structure 12) are respectively placed on two sides of the glass and stuck with the glass, then the concave surface forming device control block (the driving inclined block 23) is placed in the through hole 211, because the placing heights of the driving inclined block 23 and the cover plate 21 are different, in the hot bending machine, as the temperature rises, the glass is slowly softened, the heating plate firstly contacts the protruding concave surface forming device (the second slide structure 13) control block, so that the concave surface forming die (the second slide structure 13) pushes the glass to move towards the convex surface forming device (the first slide structure 12) and then descends to a certain distance, the side surface forming slide control frame is stressed to move, the side surface starts to form, and finally, the convex surface slide blocks (the first slide structure 12) on two sides are contacted and then move, and the side surface slide blocks (the third slide structure 14) and the convex surface forming device continue to move, so as to finally achieve annular glass forming.

In the implementation process of this embodiment, the substrate structure 11 is first placed on the chassis of the hot bending machine, the two third slider structures 14 are placed in the second slide 112, the third arc surfaces 141 are oppositely disposed, the two pieces of glass are vertically placed in the second slide 112, the two sides of the glass are respectively on the left side and the right side of the second slide 112 and are attached to the sides of the second slide 112, the two sides of the glass are respectively contacted with the four guiding surfaces 143, the two first slider structures 12 are placed at the intersection part of the first slide 111 and the second slide 112, the two first arc surfaces 121 are respectively opposite to the side surfaces of the two pieces of glass, the two second slider structures 13 are placed in the first slide 111, and the two second arc surfaces 131 are respectively opposite to the two first arc surfaces 121. The cover plate 21 is placed on the first mold assembly 10, and the driving bevel 22 is inclined at the same angle as the second bevel 1421 on the third slide structure 14, and the driving bevel and the second bevel are partially attached. Two driving inclined blocks 23 are respectively inserted into the two through holes 211, one surface of the driving inclined block 23 with an inclined surface faces the first die assembly 10, the inclined surface on the driving inclined block 23 is partially attached to the first inclined surface 1331 on the second sliding block structure 13, and the inclined angle of the driving inclined block 23 is the same as that of the first inclined surface 1331 on the second sliding block structure 13. At this time, since the glass does not begin to soften by heating, neither the first slide structure 12 nor the second slide structure 13 nor the third slide structure 14 are moved, and the second mold assembly 20 is placed on the first mold assembly 10 by the cooperation of the second slide structure 13 and the third slide structure 14. The hot bending machine is started, the temperature is gradually increased, glass is softened, the heating plate is pressed down, the heating plate is firstly contacted with the two driving inclined blocks 23, the driving inclined blocks 23 are under the pressure action, the second sliding block structure 13 is pushed to slide along the first sliding way 111 towards the direction of the first sliding block structure 12, the middle part of the glass is deformed, the two sides of the glass move along the guiding surfaces 143, and the two first sliding block structures 12 are gradually close to each other. After the glass falls to a certain distance, the heating plate is contacted with the upper surface of the cover plate 21, the cover plate 21 pushes the two third slide block structures 14 to move in the direction close to the first slide block structure 12 under the action of pressure, and the two ends of the glass start to deform. After the two first slider structures 12 contact each other, the two first slider structures 12 stop moving, and the second slider structure 13 and the third slider structure 14 continue moving until the side surfaces of the two glasses are completely attached to the two first arcuate surfaces 121, the two second arcuate surfaces 131 and the two third arcuate surfaces 141, and the two first slider structures 12 are embedded in the groove in the middle of the third arcuate surfaces 141 of the third slider structure 14. Stopping heating, cooling the glass, and finishing the hot bending pressing of the annular glass. With the second mold assembly 20 it is achieved that the second slide structure 13 and the third slide structure 14 are jointly forced to move and finish the glass by the pressure of the heating plate only. In view of the molding sequence, in this embodiment, the inclination angles of the first inclined surface 1331 and the second inclined surface 1421 are the same. In other embodiments, the dimensions of the second slide 112 and the third slider structure 14 may be modified depending on the thickness of the finished glass product to be desired.
