This standard is revised on the basis of JBz279.8 "Vertical Band Saw Series". This standard is consistent with the technical content of JB/Z279.--87, and has only been re-edited according to relevant regulations. This standard is part of JB9930 "Vertical Band Saw Series Standard". This series of standards includes the following four parts: JB/T9930.1-1999 Vertical Copper Bed Sheet Efficiency JBT9930.2-1999 Vertical Coil Bed Series Harmony JB.T9930.3-1999 Vertical Lead Bed Accuracy Inspection JR/T9930.4-1999 Vertical Constant Thirst Bed Technical Conditions This standard replaces Pan 2-1 from the date of implementation. The National Standardization Technical Committee for Cutting Machine Tools was proposed. This standard was issued by the National Standardization Technical Committee for Cutting Machine Tools Sawing Machine Branch: This standard is responsible for the unit: Hunan Machine Tool Factory. This standard was first issued in 1987. The standard specifies the series structure, purpose, characteristics, varieties and number of vertical band saws. JB/19930.2-1999, 127967. This standard applies to newly designed general-purpose vertical band saws with a large thickness of 125-500 (L). 2 Reference standards The following standards contain provisions that constitute the provisions of this standard by being cited in this standard. When this standard is published, the versions shown are valid. All standard parts will be subscribed and used. When formulating this standard, the parties may also use the latest versions of the following standards: JR7963.2-1997 Basic dimensions and tolerances of classic cutting band saw blades JB930.3-1999 Vertical band saw machine accuracy test series composition

4.1 Vertical band saw machine
JB/T9930.2—1999
Type requires sawing technology. Ordinary flat, basic flat series, suitable for single piece, small batch or batch production in metallurgy, general machinery, light industry, etc.: can do straight line or curve sawing, mainly used to add inner and outer wheel surface 1 piece (such as templates, molds and other special-shaped 1 can also be used for cutting and cutting of plate parts: can be used for cutting black metal, non-ferrous metal development with And plastic, bakelite and other non-metallic materials, the machine tool has a saw blade level change device: the lower part is powered or F-type feed device. The machine tool scale should comply with the provisions of JBT9930.3, and the following structural features are required:
1) There are two saw wheels, one for manual and one for digital:
6) There is a band saw blade tensioning device;
The lower work table can be tilted at a certain angle in the left and right directions; ) There is a band saw blade net direction device:
) There are shearing, welding, and other functional devices. 4.2 Digital vertical belt temporary bed
The machine tool has the same purpose as the corresponding basic series, and is mostly used for the wrong cutting of molds and sample wheels. In addition to the structural features of the basic series, the machine tool should also have the following structural features: 1) It has a multi-layer workbench; 2) It has an automatic control system for one or two coordinate transfer actions; 3) The longitudinal and transverse movement of the workbench is equipped with independent service devices; 4) The displacement of the longitudinal and transverse movement of the workbench should be displayed by a digital display device. 4.3 Large-end deep-type belt saws
Large-throat vertical band saws are a basic series of machines, suitable for single-piece and small-batch production in factories such as heavy machinery, sawing furnaces, lead making, extrusion and injection molding, and can do straight or curved sawing: mainly used for sawing off sheets and processing large-size molds and samples, and can cut metals, non-metals such as metal cladding, plastics, and rubber. The machine tool has a saw blade speed change device, a motorized feed or manual feed cover, and the machine tool speed reduction meets the requirements of JB/739.3. The machine tool should have the following structural features: a) There is a ground motion, a war motion, and multiple saw wheels in the middle: b) There is a saw blade lifting and stretching device: c) There is a strip guide device: d) There is a device for shearing, welding, spraying and staggering strips, etc. 4.4 Digitally controlled large-throat vertical belt unwinding machine
The machine tool has the same basic The same stamping machine series, using ten-foot-tall molds, templates and wheels, saws and machine tools, in addition to the structural characteristics of the basic model series, should have the following structural features: a) It has a multi-layer working table; b) It has one or two coordinate continuous action automatic control systems: 1) The vertical and horizontal movement of the working table are respectively equipped with independent servo devices; the displacement of the vertical and horizontal movement of the working table should be displayed by a digital display device, 5 types of vertical band saws and are also shown! ,
