Description

metal band saw

The utility model relates to a metal band saw machine, in particular to such a metal band saw machine, which uses a top seat to improve the stability of the workpiece during sawing, so that it is not easy to warp when sawing, and utilizes The cooperation of a fixing device and a torsion spring makes the saw table have a buffering effect when swinging at different angles.

The band saw machine is a fairly widely used and fairly common tool, and it is one of the must-have tools in the factory. A general band saw machine mainly includes a saw table fixed on the top of the chassis. The saw table is usually in the shape of an arch. A saw blade is fixed at the opening end of the saw table for cutting various metal workpieces. In addition, there must be a vise behind the saw table. The fixture is used for clamping one end of the workpiece when cutting, and a body is formed at the junction of the chassis and the saw table for the saw table to stand flat and upright on the chassis, and finally a motor and a switch seat are provided at one end of the saw table to When the user wants to start the band saw machine, the purpose of starting the band saw machine can be achieved directly by switching the switch seat.

The saw table of the known band saw machine and the switch base can be used to swing at different angles front and back, which mainly uses the cooperation between the seat body of the switch base and the chassis to achieve the purpose of swinging the entire saw table; The only inconvenience is that when the operator wants to adjust the up and down angles of the saw table, after opening the hook piece, he must carefully move the saw table up to the desired angle with his hand , and then fix the saw table, and when you want to swing the saw table back to the original angle, you must also use your hands to carefully hold the saw table and swing the saw table back to the original position. The saw table does not have a buffer device, so it is quite easy to cause damage to the structure between the saw table and the switch base, thereby shortening the life of the band saw machine, which is a major shortcoming of the known band saw machine;

In addition, when the known band saw machine is sawing, it mainly uses the vise clamp set at the rear of the chassis to clamp one end of the workpiece before sawing, but the known band saw machine has always had a shortcoming in sawing, that is, the vise clamp is placed on the side of the vise. When the fixture wants to clamp the workpiece, it only clamps one end of the workpiece. Therefore, when the operator is performing sawing work, the workpiece is very easy to tilt up because only one end of the workpiece is fixed, or the situation is unstable. , because when a workpiece is only fixed on one side and the other side is not stressed, it will not only easily cause the workpiece to tilt and shake, but also seriously affect the precision of the finished workpiece. Although this problem does not seem serious on the surface, In fact, for the modern industry and commerce that emphasizes excellence, it has virtually caused considerable adverse effects, affecting the competitiveness of products.

The purpose of the utility model is to provide a metal band saw machine, especially one that can fix both ends of the workpiece. When sawing, the workpiece can be quite stable without tilting or shaking, which can increase the number of finished workpieces. The precision is high, and there is a torsion spring at one end of the saw table, which can make the saw table have a buffering effect when it swings up and down, so as to improve the defect that the known structure is easy to be damaged during operation.

The purpose of this utility model is achieved in this way: a metal band saw machine, comprising: a chassis, a workbench is arranged above the chassis, a vise clamp is arranged above the workbench, a saw table is arranged above the chassis, and the saw table Form left and right cantilevers, set a saw blade at one end of the saw table, set a fixed ball at one end of the left cantilever of the saw table, set a motor above the right cantilever, and set two concave circular grooves below it, and then set another on the chassis. A switch seat is provided, and a fixing device is provided above the switch seat, and finally a buckle is fixed at one end of the chassis, and a top seat is formed at one end of the cantilever platform.

The advantages of the metal band saw machine of the present utility model are discussed as follows:

(1) The main feature of the structure of the metal band saw machine of the present utility model is that a top seat is set above the chassis, and when the workpiece can be clamped by the vise fixture, one end of the workpiece is fixed by the vise fixture, and the other end is just on top of the vise fixture. Above the top seat, when the two ends of the workpiece can be fixed, the workpiece will not be tilted or shaken when the operator is sawing the workpiece, and the precision of the finished workpiece will be increased.

(2) In the structure of the metal band saw machine of the present utility model, the saw table can be adjusted for the upper and lower angles for use when the operator saws the workpiece, especially: the utility model fixes the mandrel of the right cantilever of the saw table A torsion spring is set in the middle, and the two ends of the torsion spring are respectively supported on the two poles. In this way, when the saw table adjusts the angle of the saw blade with the spindle of the right cantilever as the rotating shaft, it is resisted by the torsion spring. The saw table has a buffer function, so when the operator adjusts the saw table for up and down angles, it can be safer, and there is no known band saw machine that is easy to damage the saw table because the saw table does not have a buffer function when adjusting the angle of the saw table. The combination between the table and the chassis can reduce the inconvenience of operation and increase the service life of this band saw machine.

(3) The metal band saw machine structure of the utility model can use the cooperation between the cantilever table convex rail and the chassis chute to achieve the adjustment of the front and rear angles, and when the saw table moves together with the switch base, the top base will also move accordingly, so the operation When the user wants to cut a workpiece with an inclined angle, the workpiece also has fixed points at both ends to make the workpiece firmly fixed, which has stability and practicability.
