Description

Technical Field

[0001] The invention relates to the technical field of hollow glass processing and manufacturing, and in particular to a universal cutter head for a spacer bending machine. Background Art

[0002] At present, in the process of insulating glass processing, the spacers used are mainly divided into two types, one is flexible warm edge spacers, and the other is non-flexible spacers. The non-flexible spacers need to be bent or spliced ​​into the required shape of insulating glass. Non-flexible spacers are divided into metal spacers, non-metal spacers, and metal and non-metal composite spacers according to the material. For non-flexible spacers, the domestic industry standard thickness is 6.5mm, and the commonly used widths are 5.5mm-26.5mm, with a wide range of widths. In foreign countries, there is a deviation between the British / American sizes and the domestic spacer width standards. For spacers of different widths, corresponding widths are required. Only a knife head with a certain degree of bending angle can produce spacer frames with qualified corner quality, otherwise it will cause problems such as out-of-tolerance bending, deformation, and breakage. Although the knife heads of existing spacer bending machines in the market have different shapes and sizes, and the structures are divided into integrated and split handles, they all have a corresponding configuration of "one knife for one strip" for spacers of different widths. Therefore, a bending machine needs to be equipped with a large number of knife heads of different widths to meet the needs of users for processing spacers of different widths. A large number of different knife heads are a production cost investment for equipment manufacturers and equipment users. At the same time, the knife changing operation also brings extra work time to the operators, reducing output efficiency. In view of the above problems, the relevant mechanisms of the bending machine need to be improved. Summary of the invention

[0003] In view of the above technical problems in the related art, the present invention provides a universal cutter head for a spacer bending machine, which can solve the above problems.

[0005] A universal cutter head for a spacer strip bending machine comprises a cutter handle, a rear fixed blade is connected to one side surface of the head end of the cutter handle, two guide shafts are also passed through the head end of the cutter handle, one end of the two guide shafts passes through the cutter handle and is connected to a guide shaft synchronous connecting plate, the other end of the two guide shafts passes through the rear fixed blade and is connected to a front movable blade, the outer side surface of the front movable blade is connected to a front blade pressure plate, and at least one compression spring is provided between the front blade pressure plate and the cutter handle.

[0006] Furthermore, the tail end of the tool handle is fixed to the bending tool head seat by a tool head fixing screw.

[0007] Furthermore, the rear fixed blade is fixed to the knife handle via a rear blade fastening screw, and the head of the rear blade fastening screw is embedded in the rear fixed blade.

[0026] In one embodiment of the present invention, the front blade fastening screw 19 passes through the front blade pressure plate 12 and the front movable blade 11 in sequence to connect to the guide shaft 9; a guide linear bearing 14 adapted to the guide shaft 9 is provided in the head end of the handle 7. The front blade pressure plate 12 is provided to better install the compression spring 13, and the guide linear bearing 14 is provided to better enable the guide shaft 9 to perform linear motion.
