Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a punching device for producing and processing tempered glass. Background Art

[0002] Tempered glass is a safety glass. In order to improve the strength of the glass, compressive stress is formed on the glass surface by physical or chemical methods. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own wind pressure resistance, cold properties and impact resistance. Therefore, tempered glass is widely used in various fields, such as gas stoves, range hood panels, decorative glass, etc. When tempered glass is used, the existing tempered glass needs to be punched before being tempered, so as to facilitate hanging, transportation or installation, thus using a special glass punching machine.

[0003] The existing tempered glass punching machine needs to fix the tempered glass when working. In order to solve the fixing problem, the application number CN 214562015 U discloses a tempered glass punching device, including an upper suction cup and a lower suction cup, the upper suction cup and the lower suction cup are arranged opposite to each other, the lower suction cup is slidably connected to the slideway, the lower end of the slideway is fixedly connected to the first hydraulic cylinder, the upper suction cup is fixedly connected to the spring telescopic rod, the spring telescopic rod is fixedly connected to the motor mounting platform, and the upper end of the motor mounting platform is fixedly connected to the second hydraulic cylinder. When the glass is placed on the lower suction cup, the tempered glass is kept in a stable position during processing through the action of the upper suction cup and the lower suction cup, and the top of the glass can avoid the glass being clamped too tight or too loose through the elastic extrusion of the spring telescopic rod; the position of the lower suction cup is adjusted according to the size of the tempered glass to avoid the instability of the center of the tempered glass on the lower suction cup due to the difference in size and shape.

[0004] However, the glass fixed by the suction cup may be adsorbed by the suction cup after drilling is completed. If it is adsorbed by the upper suction cup, the glass will fall during the release process. If it is adsorbed by the lower suction cup, it will be difficult for the user to remove it. In addition, manual control is required during the drilling process, and the degree of automation is low, resulting in low efficiency. Utility Model Content
