Inclined wedge block hold-down device for sawtooth material

Abstract

The invention discloses an inclined wedge block hold-down device for a sawtooth material. The inclined wedge block hold-down device for the sawtooth material comprises a base, a lower clamping block and an upper clamping block, wherein the lower clamping block is fixed on the base; the upper clamping block is matched with the lower clamping block to clamp the sawtooth material; the upper clamping block is hinged with the base through a rotating shaft; a driving mechanism for driving the upper clamping block to move around the rotating shaft is also provided; the driving mechanism comprises a cylinder and an inclined wedge block; the cylinder is arranged on the base; the inclined wedge block is fixedly connected with a piston rod on the cylinder; and the inclined wedge block is provided with an inclined surface abutted against the upper clamping block. The inclined wedge block hold-down device is reliable and simple in hold-down, simple in structure, convenient to assemble, simple in operation and good in hold-down effect, reduces serious waste caused by frequent exchange of upper clamping block, reduces using cost and has great practical and popularization value.

Description

technical field [0001] The invention relates to a clamp used in the welding process of metal band saw blades, in particular to a pressing device for tooth material wedge blocks. Background technique [0002] Bimetal band saw blade is a high-tech product processed by two kinds of steel with different characteristics through a series of processes such as electron beam welding, machining and heat treatment. It is an industrial consumable used in conjunction with band sawing machines. Steel and copper, aluminum and other non-ferrous metals. [0003] In 1933, the American Doall (DOALL) company invented the band saw machine and the band saw blade. The principle is to use a circular saw belt to cut metal. At the beginning of its birth, the band saw machine used a single metal band saw blade for cutting, and its material was carbon tool steel. After 32 years of repeated research, in 1963 Dürr switched to alloy tool steel to manufacture band saw blades, and successfully developed t...

Problems solved by technology

[0010] For the sawtooth positioning and pressing device, since the cylinder 14 is placed vertically, it occupies a relatively large space, and this placement method is inconvenient to operate

And because the pressing force of the device is generated by the cylinder 14 directly acting on the upper clamping block 1, the shaking or eccentricity of the cylinder 14 will cause the upper clamping block 1 to shift, which is not conducive to accurate positioning and fixing

The upper clamping block 1 directly acts on the tooth material 16, so that the upper clamping block 1 is easy to wear and consume, and the upper clamping block 1 needs to be replaced frequently to ensure its positioning and pressing effect, and the replaced upper clamping block 1 is often used as a waste product , resulting in serious waste
