Description

Technical Field

[0001] This application relates to the technical field of bending machines, and particularly to a novel bending machine for bending aluminum spacers. Background Art

[0002] The aluminum spacer frame is one of the essential materials for manufacturing insulating glass, and its quality directly affects the service effect, service life, and heat insulation function of the insulating glass. The aluminum spacer frame is formed by bending aluminum spacers with a bending machine.

[0003] The existing bending machine drives the aluminum spacer to perform the bending operation by manually pulling the bending rod, so that the aluminum spacer is bent into a square shape. This bending method of the aluminum spacer is relatively slow, with low work efficiency, and greatly increases the production cost of the aluminum spacer frame.

[0052] The first telescopic component 603 includes a first telescopic main body and a first telescopic rod which are sleeved with each other. In this embodiment, the first telescopic component 603 is a hydraulic cylinder, where the first telescopic main body is the hydraulic cylinder housing and the first telescopic rod is the hydraulic cylinder piston rod; similarly, the second telescopic component 605 includes a second telescopic main body and a second telescopic rod which are sleeved with each other.

Both the first support block 201 and the second support block 202 are hinged with claw-shaped sliders 7, and the claw-shaped sliders 7 are slidably connected to the first bending member 3.

[0055] As Figure 4 shown, the specific structure for the first bending member 3 to achieve rotation is described as follows: The first bending member 3 includes a bending plate 301. The bending plate 301 is fixedly connected to the first fixing block 302. One end of the first rotating shaft is fixedly connected to the first fixing block 302.

The sliding base 1402 is hinged to the eighth telescopic rod, and the eighth telescopic main body is hingedly installed on the slide rail base 1405. Therefore, when the third motor 1404 operates, the serrated disc 1401 rotates, and the eighth telescopic component 1406 operates, causing the serrated disc 1401 to move back and forth in a direction perpendicular to the mounting plate 1. Further, a waste bin is installed below the front sawing notch of the sawing component 14. The waste bin is used to catch the fine waste generated when the serrated disc 1401 saws off the aluminum spacer.

[0070] Therefore, the side length of the rectangular aluminum frame or triangular aluminum frame is the distance between the sawing point and the bending point of the serrated disc 1401. It should be noted that the position of the slide rail base 1405 installed on the mounting plate 1 in this embodiment can be adjusted. Therefore, the position of the sawing component 14 can be adjusted, that is, the side length of the rectangular aluminum frame or triangular aluminum frame can be adjusted.

[0071] Such as Figure 7 and 8 As shown, the product of this embodiment is installed on the support main frame. A feeding component and a storage component are installed on the support main frame. The storage component is used to store aluminum spacers, and the feeding component is used to convey aluminum spacers. During the bending process of the aluminum spacer, the aluminum spacer is drawn out from the storage component and conveyed by the feeding component, and is placed on the feeding table 2 through the front sawing notch of the sawing component 14.

[0072] The working process of this embodiment will be further described below:

[0073] The serrated disc 1401 in the sawing component 14 moves backward, leaving the front sawing notch open;

[0074] The aluminum spacer is conveyed from the storage component to the feeding table 2 under the action of the feeding component;

[0075] The third telescopic component 305 operates, and the L-shaped clamping plate 304 and the bending plate 301 are clamped and matched to clamp the aluminum spacer on the bending plate 301;

[0076] The bending point pressing rod 4 presses the aluminum spacer bar downward, and the first bending member 3, the second bending member 8, and the third bending member 10 are successively operated;

[0077] After bending the aluminum spacer bar into 90°, the L-shaped clamping plate 304 releases the aluminum spacer bar on the bending plate 301;

[0078] The conveying assembly continues to convey the aluminum spacer bar forward. The L-shaped clamping plate 304 clamps the aluminum spacer bar on the bending plate 301, the bending point pressing rod 4 presses the aluminum spacer bar downward, and the first bending member 3, the second bending member 8, and the third bending member 10 are successively operated;

[0079] And so on, the bending of a rectangular aluminum frame is completed. Finally, the sawtooth disk 1401 in the sawing assembly 14 operates and moves forward to saw off the redundant saw teeth.

[0080] The above are only the preferred embodiments of the present application, and do not impose any form of limitation on the present application. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes. Therefore, all equivalent changes made according to the shape, structure, and principle of the present application without departing from the content of the technical solution of the present application shall be covered by the protection scope of the present application.
