Abstract
The utility model relates to a broach for molding adjustable spanner row teeth at one step, and the broach is used for broaching and molding shapes and sizes of adjustable spanner row teeth at one step. The broach includes a bottom plate (4) and a broaching body (1), wherein the broaching body (1) is arranged at the middle of the upper end surface of the bottom plate (4); a protruding rail (41) is protruded upwards at the middle of the upper end surface of the bottom plate (4) and in the length direction of the bottom plate (4); a groove (41) matched with the protruding rail is concaved upwards in the middle of the lower end surface of the broaching body (1) and in the length direction of the broaching body (1); a plurality of through holes (42) are vertically formed on each of two sides of the bottom plate (4) and in the length direction of the broaching body (1); a plurality of edges (2) are formed on the upper end surface of the broaching body (1) and in the length direction of the broaching body (1); the edges (2) are arranged in the direction perpendicular to the length direction of the broaching body (1); a chip pocket (3) is formed between every two adjacent edges (2); and a plurality of retaining screw holes are vertically formed in the middle of the upper end surface of the broaching body (1) and in the length direction of the broaching body (1). The broach can improve the molding efficiency and the molding quality of adjustable spanner row teeth.
Description
(1) technical field
The utility model relates to a kind of moulding broaching tool, is used for the disposable broaching moulding of each shape and size of blank adjustable wrench toothrow.Belong to steel processing cutting technology field.
(2) background technology
The adjustable wrench toothrow is traditional hardware ﹠ tools, and scope is wide, consumption is big.In recent years, both at home and abroad demand also constantly increases, and style and having higher requirement qualitatively.In the past, the production of adjustable wrench toothrow all was based on Milling Process, with profile milling cutter Milling Process on production miller of high-speed tool steel manufacturing.Its shortcoming is: work efficiency is low, of poor quality, noise is big, labour intensity is big, fineness is crude, and each position precision does not reach requirement.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can be to the adjustable wrench toothrow one-shot forming broaching tool of the disposable broaching moulding of each shape and size of blank adjustable wrench toothrow.
The purpose of this utility model is achieved in that a kind of adjustable wrench toothrow one-shot forming broaching tool, comprise base plate and broaching tool cutter hub, the broaching tool cutter hub is arranged in the middle of the base plate upper surface, be provided with a protruding rail along the floor length direction is protruding upward in the middle of the base plate upper surface, corresponding to this protruding rail, upwards be concaved with a groove with matching along broaching tool cutter hub length direction in the middle of the broaching tool cutter hub lower surface, vertically be provided with several through holes at base plate two edge broaching tool cutter hub length directions; Be evenly equipped with several cutting edges in described broaching tool cutter hub upper surface along broaching tool cutter hub length direction, described cutting edge and vertical setting of broaching tool cutter hub length direction, described cutting edge is convex, spill or line strip, forms chip pocket between the adjacent cutting edge; In the middle of described broaching tool cutter hub upper surface, vertically be provided with several fixed screw holes along broaching tool cutter hub length direction.
Become adjustable wrench toothrow different shape by above these blade shapes, disposable can be to blank adjustable wrench toothrow broaching Surface Finishing to finished size, and have characteristics such as easy to operate, long service life.Cutting edge wearing and tearing can be on broach grainding machine grinding cutting edge anterior angle, continue to use, do not influence product quality.
The beneficial effects of the utility model are:
Use this adjustable wrench toothrow one-shot forming broaching tool, can improve adjustable wrench toothrow moulding work efficiency, improve adjustable wrench toothrow Forming Quality, and moulding broaching tool complex-shaped, special type can be provided.Safe and reliable.
