Detailed implementation manners

[0038] Please refer to Figures 1-12 , the present invention provides a technical solution: a pressing and forming device and method for a special-shaped glass railing panel, including a bottom plate 1, and a support frame 2 is fixedly connected to the bottom plate 1;

[0039] A pressing mechanism is provided on the support frame 2, and the pressing mechanism is used for pressing the melted glass paste into a flat glass;

[0040] A cutting mechanism is provided in the pressing mechanism, and the cutting mechanism is used for cutting the pressed flat glass into the required special-shaped shape and the cutting mechanism in the pressing mechanism is replaceable;

[0041] A driving mechanism is provided on the support frame 2, and the driving mechanism is used for driving the pressing mechanism and the cutting mechanism to run successively;

[0042] A replacement mechanism is provided on the bottom plate 1, and the replacement mechanism is used for replacing the cutting mechanism that has completed cutting in the pressing mechanism with a new cutting mechanism;

[0043] During operation, when producing special-shaped glass, first put the melted glass paste into the pressing mechanism, and then start the driving mechanism. The driving mechanism drives the pressing mechanism to start pressing the glass paste into a flat shape. Since the edge shape of the pressed flat glass paste is irregular and the required special-shaped shape cannot be pressed, at this time, the driving mechanism starts to drive the cutting mechanism to run, and the cutting mechanism cuts out the middle part of the glass paste pressed into a flat shape in the required special-shaped shape, so that the required special-shaped glass railing panel can be obtained;

[0044] After the cutting mechanism cuts out the required special-shaped glass railing panel, since the temperature of the glass railing panel is relatively high at this time and it takes a certain amount of time to cool down, the replacement mechanism is started at this time. Through the replacement mechanism, a new cutting mechanism can replace the cutting mechanism that has completed the cutting. The cutting mechanism that has completed the cutting can be used to cool the glass railing panel at this time, while the new cutting mechanism can be used for the next round of cutting of flat glass, thereby improving the efficiency of pressing the special-shaped glass railing panel. At the same time, since the cutting mechanism cuts in the middle part of the glass plate that has been pressed and formed, the glass paste put in does not need to be strictly kept in a fixed quantity.

[0045] As Figures 4-6 , Figure 11 shown, as a further solution of the present invention, the pressing mechanism includes a lower pressing plate 3 and an upper pressing plate 4. Four sliding rods 5 are fixedly connected to the lower pressing plate 3, and first springs 6 are sleeved on all four sliding rods 5; the upper pressing plate 4 is slidably connected to the four sliding rods 5; one end of the first spring 6 is fixedly connected to the upper pressing plate 4 and the other end is fixedly connected to the sliding rod 5; the bottom side part of the lower pressing plate 3 is clamped and matched with the support frame 2. Screws 7 are symmetrically arranged on the support frame 2 at the left and right positions where it is clamped with the lower pressing plate 3. The screws 7 are threadedly connected to both the support frame 2 and the lower pressing plate 3;

[0046] The cutting mechanism includes two cutting plates 8, and the two cutting plates 8 are respectively located at the middle positions inside the upper pressing plate 4 and the lower pressing plate 3; the lower surface of the upper cutting plate 8 is flush with the lower surface of the upper pressing plate 4 and the upper surface of the lower cutting plate 8 is flush with the upper surface of the lower pressing plate 3; first clamping mechanisms are arranged inside both the upper pressing plate 4 and the lower pressing plate 3. The first clamping mechanism is used to clamp the upper and lower cutting plates 8 inside the upper pressing plate 4 and the lower pressing plate 3 respectively, and release the upper and lower cutting plates 8 when the upper pressing plate 4 and the lower pressing plate 3 are attached to the required thickness of the glass to be pressed;

[0047] The first clamping mechanism includes two groups of first clamping blocks 9, and the two groups of first clamping blocks 9 are respectively located inside the upper pressing plate 4 and the lower pressing plate 3; one group of first clamping blocks 9 includes four first clamping blocks 9. The four first clamping blocks 9 on the upper and lower sides are respectively located at the front, rear, left and right positions of the upper pressing plate 4 and the lower pressing plate 3 and are respectively slidably connected to the upper pressing plate 4 and the lower pressing plate 3; the four first clamping blocks 9 on the upper and lower sides are respectively clamped and matched with the upper and lower cutting plates 8; a second spring 10 is fixedly connected to one end of the outer side of the first clamping block 9. The other ends of the second springs 10 on the upper and lower sides are respectively fixedly connected to the upper pressing plate 4 and the lower pressing plate 3; a push block 11 is fixedly connected to one end of the outer side of the upper first clamping block 9, and a push frame 12 is slidably connected to one end of the outer side of the lower first clamping block 9. The push frame 12 is located directly below the push block 11 and a first connecting rod 13 is provided at the bottom end of the push frame 12. One end of the first connecting rod 13 is rotatably connected to the push frame 12 and the other end is rotatably connected to the lower pressing plate 3;

[0048] During operation, the molten glass paste is placed on the lower pressing plate 3, and then the upper pressing plate 4 is driven to move downward to press the glass paste. Under the action of the upper pressing plate 4 and the lower pressing plate 3, the glass paste begins to gradually flatten; when the distance between the upper pressing plate 4 and the lower pressing plate 3 reaches the thickness of the glass railing to be pressed, the glass paste is then pressed into an irregular glass plate with the required thickness;

[0049] When the upper pressing plate 4 moves downward, the upper pressing plate 4 will drive the four push blocks 11 on the upper side to move downward. The four push blocks 11 are respectively inserted into the four push frames 12 on the lower side. After the push blocks 11 are completely inserted into the push frames 12, when the upper pressing plate 4 continues to move downward, the push blocks 11 begin to drive the push frames 12 to move downward. When the push frames 12 move downward, under the action of the first connecting rod 13, the push frames 12 will also displace outward at the same time. When the push frames 12 displace outward, they will drive the first clamping blocks 9 on the upper and lower sides to move outward at the same time; when the upper pressing plate 4 moves downward to the set position, at this time, the first clamping blocks 9 on the upper and lower sides just separate from the cutting plates 8 on the upper and lower sides respectively. When the cutting plates 8 on the upper and lower sides are driven to move downward, the cutting plates 8 will cut off the middle part of the pressed glass plate in the shape of the cutting plates 8, so as to obtain the required special-shaped glass railing;

[0050] Since the shape of the glass railing cut by the cutting plate 8 is the same as the shape of the cutting plate 8, when it is necessary to press another shape of glass railing, the lower pressing plate 3 and the upper pressing plate 4 can be taken out of the support frame 2 by removing the screws 7, and then the new upper pressing plate 4 and the upper pressing plate 4 can be replaced.

[0051] As Figure 9 、 Figure 11 shown, as a further solution of the present invention, the driving mechanism includes a first air cylinder 14, and the first air cylinder 14 is fixedly connected to the support frame 2; first clamping blocks 15 are fixedly connected above the upper pressing plate 4 and below the lower pressing plate 3. A first clamping frame 16 is provided on the first clamping block 15, and the first clamping frame 16 is slidably connected to the first clamping block 15; the upper first clamping frame 16 is fixedly connected to the first air cylinder 14, and the bottom end of the lower first clamping frame 16 is fixedly connected with a support plate 17. The support plate 17 is attached to the lower part of the lower pressing plate 3, and the bottom end of the support plate 17 is fixedly connected with a first telescopic rod 18. The bottom end of the first telescopic rod 18 is fixedly connected to the bottom plate 1; a third spring 19 is sleeved on the first telescopic rod 18. The upper end of the third spring 19 is fixedly connected to the support plate 17, and the bottom end of the third spring 19 is fixedly connected to the bottom plate 1;

[0052] During operation, starting the first cylinder 14 can drive the upper cutting plate 8 and the upper pressing plate 4 to move downward simultaneously. When the upper pressing plate 4 moves downward to the position where it fits against the lower pressing plate 3, the upper and lower cutting plates 8 are disengaged from the upper pressing plate 4 and the lower pressing plate 3 respectively. At this time, the first cylinder 14 can drive the upper and lower cutting plates 8 to continue moving downward; when the first cylinder 14 drives the upper and lower cutting plates 8 to continue moving downward, the upper and lower cutting plates 8 will cut out the required shape from the middle part of the pressed glass plate, and at the same time, the lower cutting plate 8 will push the support plate 17 downward; when the upper and lower cutting plates 8 move downward to the lowest position, the new two cutting plates 8 can be replaced with the two cutting plates 8 that have completed the cutting; after the replacement is completed, start the first cylinder 14 to drive the upper cutting plate 8 to move upward. Under the action of the third spring 19, the support plate 17 will drive the lower cutting plate 8 to move upward; the first cylinder 14 drives the upper cutting plate 8 to move into the upper pressing plate 4, and the third spring 19 will drive the lower cutting plate 8 to move into the lower pressing plate 3.

[0053] As Figures 7-10 shown, as a further solution of the present invention, the replacement mechanism includes a rotating frame 20, the rotating frame 20 is rotatably connected to the bottom plate 1 and the rotating frame 20 is driven by a motor; six second telescopic rods 21 are fixedly connected to the rotating frame 20, and the six second telescopic rods 21 are circumferentially arranged on the rotating frame 20; an inserting frame 22 is fixedly connected to the second telescopic rod 21, and the upper and lower cutting plates 8 are respectively inserted and matched with the upper and lower parts of the inserting frame 22; a push rod 23 is fixedly connected to the bottom of the inserting frame 22; a second cylinder 24 is fixedly connected to the bottom plate 1, a driving frame 25 is fixedly connected to the rear end of the second cylinder 24, and the driving frame 25 is in clearance fit with the push rod 23 at the rearmost position; a second engaging mechanism is provided at the bottom of the support plate 17, and the second engaging mechanism is used to lock the support plate 17 when the support plate 17 moves downward to the lowest position, facilitating the replacement of the upper and lower cutting plates 8;

[0054] The second engaging mechanism includes two second engaging blocks 26, the two second engaging blocks 26 are located at the front and rear positions at the bottom of the support plate 17 and the two second engaging blocks 26 are fixedly connected to the support plate 17; a third engaging block 27 is provided at the bottom of the second engaging block 26, the third engaging block 27 is slidably connected to the bottom plate 1 and a fourth spring 28 is fixedly connected to the third engaging block 27, and the other end of the fourth spring 28 is fixedly connected to the bottom plate 1; a releasing mechanism is provided on the bottom plate 1, and the releasing mechanism is used to drive the two third engaging blocks 27 to disengage from the two second engaging blocks 26 respectively after the rearmost inserting frame 22 is disengaged from the upper cutting plate 8 and the lower cutting plate 8;

[0055] The release mechanism includes a connecting rod 29. The connecting rod 29 is fixedly connected to the driving frame 25, and a first driving rod 30 is rotatably connected to the rear end of the connecting rod 29. The first driving rod 30 is inclined at 45 degrees relative to the connecting rod 29, and a stop rod 31 is fixedly connected to the first driving rod 30. The stop rod 31 is parallel to the connecting rod 29 and fits against the connecting rod 29. A torsion spring is provided at the connection position between the first driving rod 30 and the connecting rod 29. A driving plate 32 is provided at the left rear position of the connecting rod 29, and a second driving rod 33 is fixedly connected to the driving plate 32. The second driving rod 33 is located behind the first driving rod 30. The second connecting rods 34 are symmetrically and rotatably connected to the front and rear positions of the driving rod. The other ends of the front and rear second connecting rods 34 are respectively rotatably connected to the front and rear third clamping blocks 27.

[0056] During operation, when the first cylinder 14 drives the two cutting plates 8 that have completed cutting to move downward to the lowest position, the second cylinder 24 is started at this time. The second cylinder 24 drives the driving frame 25 to move backward. The driving frame 25 will push the rearmost inserting frame 22 backward through the push rod 23 and insert it into the two cutting plates 8 that have completed cutting. At this time, the rotating frame 20 can be started to rotate. The rotating frame 20 drives the two cutting plates 8 that have completed cutting to be separated from the upper and lower clamping frames respectively, and drives the two cutting plates 8 at the next position to be engaged with the upper and lower clamping frames respectively. After the new two cutting plates 8 are engaged with the upper and lower clamping frames, the second cylinder 24 is started to drive the driving frame 25 to move forward. The driving frame 25 drives the rearmost inserting frame 22 to move forward through the push rod 23 and separate from the two cutting plates 8.

[0057] Since the driving frame 25 drives the connecting rod 29 to move forward when it moves forward, the connecting rod 29 drives the first driving rod 30 to move forward, and the first driving rod 30 will move toward the position closer to the second driving rod 33. When the driving frame 25 drives the insertion to move to the position separated from the two cutting plates 8, the first driving rod 30 just moves to the position in contact with the second driving rod 33. As the connecting rod 29 drives the first driving rod 30 to continue moving forward, the first driving rod 30 will push the second driving rod 33 to move leftward. The second driving rod 33 drives the driving plate 32 to move leftward. When the driving plate 32 moves leftward, it respectively pushes the front and rear third clamping blocks 27 forward and backward through the two second connecting rods 34. The front and rear third clamping blocks 27 are separated from the front and rear second clamping blocks 26 respectively. The support plate 17 will drive the lower cutting plate 8 to start moving upward under the action of the third spring 19.

[0058] As Figure 11As shown in the figure, as a further solution of the present invention, a third cylinder 35 is fixedly connected to the rear side position of the support frame 2. A sliding frame 36 is fixedly connected to the third cylinder 35. The sliding frame 36 is slidably connected to the support frame 2, and a limiting frame 37 is fixedly connected to the front side position of the sliding frame 36. The limiting frame 37 is located between the upper pressing plate 4 and the lower pressing plate 3, and the area of the limiting frame 37 is equal to the areas of the upper pressing plate 4 and the lower pressing plate 3.

[0059] During operation, before driving the upper pressing plate 4 to press the glass plate, by starting the third cylinder 35, the limiting frame 37 can be driven to move to the position between the upper pressing plate 4 and the lower pressing plate 3. The limiting frame 37 can prevent the glass paste from flowing out of the upper pressing plate 4 during pressing. After the cutting of the glass plate is completed, by starting the third cylinder 35 to drive the limiting frame 37 to move backward, the limiting frame 37 can clean the residual glass plate on the upper pressing plate 4.

[0060] As a further solution of the present invention, a method for pressing and forming a special-shaped glass railing panel, the specific steps of the method are as follows:

[0061] Step 1: Put an appropriate amount of melted glass paste into the pressing mechanism, and then start the driving mechanism. The driving mechanism drives the pressing mechanism to press the glass paste into a flat glass plate.

[0062] Step 2: After the pressing mechanism presses the glass paste into a glass plate, the driving mechanism drives the cutting mechanism to operate, and the cutting mechanism will cut the pressed glass plate into a specific shape.

[0063] Step 3: After the cutting mechanism completes the cutting, start the replacement mechanism, and the replacement mechanism replaces the completed cutting mechanism with a new cutting mechanism.
