Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a hot bending positioning device for tempered glass processing. Background Technology

[0002] The hot bending equipment used in tempered glass processing is a device specifically designed to heat and bend tempered glass into a specific shape. Generally, the tempered glass is heated to its softening point by a heating system, and then bent into the desired shape using a mold or mechanical force.

[0003] Chinese utility model patent application number 202221267777.0 discloses a tempered glass hot bending processing mold, including a base plate, a glass hot bending unit, a glass pressing unit, and a glass picking unit; the base plate is rectangular; the glass hot bending unit includes a screw, bearings, a fixing plate, a sliding plate, a rectangular sealing plate, a rectangular slider, U-shaped slide rails, a rectangular hot bending box, a temperature control switch, a replaceable hot bending mold body, a rectangular heating element, a second screw, and a knob. The two ends of the upper surface of one end of the base plate are respectively fixedly connected to the lower ends of two corresponding U-shaped slide rails, and the upper ends of the two U-shaped slide rails are respectively fixedly connected to the two ends of the lower surface of the fixing plate. This mold can process glass with various bending curvatures to meet different usage requirements.

[0004] However, in this technical solution, during the glass hot bending process, when the glass is pulled upwards, the clamping end of the glass will change with the curvature, resulting in an upward tilt. The glass and the clamping mechanism change from a close fit to an inclined state, which will lead to a poor clamping effect of the clamping mechanism on the glass, causing the glass to shift and resulting in an unsatisfactory hot bending effect.

[0005] Therefore, it is necessary to solve the above problems by using a hot bending positioning device for tempered glass processing. Utility Model Content

[0006] The purpose of this invention is to provide a hot bending positioning device for tempered glass processing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hot bending positioning device for tempered glass processing, comprising an operating table, a heating box provided on the operating table, pushing components symmetrically arranged on the heating box, a guide strip provided at the bottom of the heating box, a lifting component provided on the pushing component, a top block provided on the lifting component, and clamping components symmetrically arranged inside the heating box;

[0008] The clamping assembly includes a base plate and a top plate. A clamping spring is provided on the bottom surface of the top plate, and a clamping plate is connected to the side of the clamping spring away from the top plate.

[0009] Preferably, the clamping assembly further includes a C-shaped plate, the bottom plate and the top plate are slidably disposed on the C-shaped plate, the C-shaped plate is provided with a track groove, and sliders are provided at both ends of the bottom plate and the top plate.

The bottom plate is provided with an anti-slip pad, and the two ends of the C-shaped plate are fixedly connected with steering motors.

[0012] Preferably, the pushing component includes a telescopic cylinder, which is fixedly mounted on the operating table by a mounting plate, and the output end of the telescopic cylinder passes through the heating box and is connected to a push plate.

A connecting block is hinged to the end of the rotating plate away from the rotating shaft, and the connecting block is fixedly mounted on the bottom surface of the top block.

[0015] The technical effects and advantages of this utility model are:

[0016] 1. In this utility model, a heating box is set to heat the glass, and then a pushing component pushes a lifting component. The lifting component drives the top block to bend the glass.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] To address the issue that during the glass hot bending process, when the glass is pulled upwards, the clamping end of the glass changes with the curvature, resulting in upward tilting and loosening of the clamp, which leads to glass displacement and ultimately unsatisfactory hot bending results, the following embodiments are proposed.

[0026] This utility model provides, for example Figures 1 to 5 The hot bending positioning device for tempered glass processing shown includes an operating table 1, a heating box 2 on the operating table 1, a heating device inside the heating box 2 for heating the glass, a cover on the top of the heating box 2, pushing components 3 symmetrically arranged on the heating box 2, a guide bar 4 at the bottom of the heating box 2, a lifting component 5 on the pushing component 3, a top block 6 on the lifting component 5, and clamping components 7 symmetrically arranged inside the heating box 2.

[0027] The glass is heated by a heating box 2, and then the lifting component 5 is pushed by the pushing component 3. The lifting component 5 drives the top block 6 to bend the glass. During the bending process, the glass is clamped and positioned by a clamping component 7. As the curvature of the glass changes, the clamping direction of the clamping component 7 changes accordingly to prevent the clamping end of the glass from bending, thereby affecting the hot bending effect of the glass.

[0028] like Figure 3 As shown, the clamping assembly 7 includes a base plate 701 and a top plate 702. Clamping springs 705 are arranged in two rows on the bottom surface of the top plate 702, evenly distributed. A clamping plate 704 is connected to the side of the clamping springs 705 away from the top plate 702. Through holes are provided at both ends of the clamping plate 704, with a diameter larger than that of the screw 708. The inner wall of the through holes does not contact the screw 708. The clamping assembly 7 also includes a C-shaped plate 703. The base plate 701 and the top plate 702 are slidably mounted on the C-shaped plate 703, which has a track groove. Both ends of the base plate 701 and top plate 702 are equipped with sliders, which are engaged in the track grooves and can slide along the track grooves. A fixing frame 706 is symmetrically arranged on the C-shaped plate 703, and an adjusting motor 707 is fixedly mounted on the fixing frame 706. A screw 708 is fixedly connected to the output end of the adjusting motor 707. Both the base plate 701 and top plate 702 are provided with threaded holes, and the threads in the threaded holes on the base plate 701 and top plate 702 are in opposite directions, so that when the adjusting motor 707 drives the screw 708 to rotate, the base plate 701 and top plate 702 can move closer to each other or further away. The screw 708 is threadedly connected to the base plate 701 and top plate 702 through the threaded holes respectively. An anti-slip pad 709 is provided on the base plate 701, and anti-slip strips are provided on the anti-slip pad 709. An auxiliary clamping plate 704 clamps and positions the glass. A steering motor 710 is fixedly connected to both ends of the C-shaped plate 703.

[0029] In use, the user places both ends of the glass between the clamping plate 704 and the base plate 701, and then controls the adjustment motor 707 to rotate, which drives the screw 708 to rotate. The screw 708 drives the base plate 701 and the top plate 702 to move closer to each other until the clamping plate 704 presses the ends of the glass. At this time, the glass is in a horizontal state, and the compression of the two rows of clamping springs 705 is consistent. When the heating box 2 heats and softens the glass, the top block 6 presses against the middle of the glass and lifts it upward. The glass changes from a horizontal state to an arc state, and the two clamping ends of the glass will tend to curl upward as the glass arc is generated.

[0030] When the compression of one row of clamping springs 705 increases significantly while the other row remains unchanged or increases only slightly, it indicates that the glass is tilting upwards and the clamping is loose. At this time, the steering motor 710 is controlled to rotate, which drives the C-shaped plate 703 to rotate, thereby driving the clamping plate 704, the bottom plate 701, and the top plate 702 to rotate until the compression of the two rows of clamping springs 705 is consistent. This indicates that the glass has returned to a clamped state, and the rotation of the steering motor 710 is stopped.

[0031] The glass is clamped by setting up a clamping plate 704, a clamping spring 705, and a base plate 701. The clamping status of the clamping plate 704 is detected by the change in the compression of the clamping spring 705. Then, the C-shaped plate 703 is controlled to rotate, thereby causing the clamping plate 704 and the base plate 701 to rotate with the curvature of the glass bending, ensuring the curvature of the glass clamping end and avoiding bending of the glass clamping end, which would lead to a deterioration in the hot bending effect.

[0032] like Figures 4-5 As shown, the pushing component 3 includes a telescopic cylinder 301, which is fixedly mounted on the operating table 1 via a mounting plate 302. The output end of the telescopic cylinder 301 passes through the heating box 2 and is connected to a push plate 303. A groove 304 is provided on the push plate 303, which is engaged with the guide strip 4. The push plate 303 slides along the guide strip 4. The lifting component 5 includes a hinge block 501, which is fixedly mounted on the push plate 303. A rotating shaft 502 is hinged to the hinge block 501, and a rotating plate 503 is fixedly mounted on the rotating shaft 502. A connecting block 504 is hinged to one end of the rotating plate 503 away from the rotating shaft 502. The connecting block 504 is fixedly mounted on the bottom surface of the top block 6.

[0033] In use, the output end of the telescopic cylinder 301 is extended, which drives the push plate 303 to move along the guide bar 4. The push plate 303 drives the hinge block 501 to move. The hinge block 501 drives the rotating plate 503 to rotate through the rotating shaft 502. The rotating plate 503 pushes the top block 6 to rise through the connecting block 504, thereby pushing the middle of the glass to rise, thus completing the bending of the glass.

[0034] The working principle of this utility model is as follows: First, fix the glass, open the cover of the heating box 2, and the user places both ends of the glass between the clamping plate 704 and the bottom plate 701. Then, control the adjustment motor 707 to rotate, which drives the screw 708 to rotate. The screw 708 drives the bottom plate 701 and the top plate 702 to move closer to each other until the clamping plate 704 presses the ends of the glass. At this time, the glass is in a horizontal state, and the compression of the two rows of clamping springs 705 is consistent.

[0035] Next, the glass is heated by activating the heating device inside the heating chamber 2 until it reaches its softening point.

[0036] Then, bending is performed. The output end of the telescopic cylinder 301 extends, causing the push plate 303 to move along the guide bar 4. The push plate 303 drives the hinge block 501 to move. The hinge block 501 drives the rotating plate 503 to rotate via the rotating shaft 502. The rotating plate 503 pushes the top block 6 up via the connecting block 504. The top block 6 presses against the middle of the glass and pushes it upward, changing the glass from a horizontal state to an arc shape, thus completing the bending process. During the bending process, the two clamping ends of the glass will tend to curve upward as the glass curvature is created.

[0037] Finally, adjust the clamping orientation and judge whether the glass clamping is loose by the change in the compression of the clamping springs 705. When the compression of one row of clamping springs 705 increases significantly while the other row remains unchanged or increases only slightly, it means that the glass is tilted upward and the clamping is loose. At this time, control the steering motor 710 to rotate, which drives the C-shaped plate 703 to rotate, thereby driving the clamping plate 704, the bottom plate 701 and the top plate 702 to rotate until the compression of the two rows of clamping springs 705 is consistent. This means that the glass has returned to a clamped state. Stop the rotation of the steering motor 710 to complete the adjustment of the clamping orientation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
