Abstract
The invention discloses a bolt toothed bar mould which is characterized by comprising a body, wherein the body is provided with two end surfaces, and one side of a core cavity is provided with a sizing belt; the body comprises a mould sleeve and a mould core, wherein the mould sleeve is positioned on the periphery of the mould core and is compressed with the mould core together, and a cavity of the body is formed in the middle of the mould core. The bolt toothed bar mould can mould a bolt toothed bar once, and the moulded rolling toothed diameter part which can be peeled off by a turning machine originally can be extruded and extended to reach the required size of a product. The bolt toothed bar mould saves raw materials, labor hours and cost, increases work efficiency and productivity and can effectively control product quality.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to the tooth bar one-time-shaped mould of a kind of standard component king-bolt and non-standard component king-bolt.
Background technology
Fig. 1 is a conventional bolt tooth bar processing mode schematic diagram.
As shown in Figure 1: the bar of traditional standard component bolt 1 and non-standard component bolt 1 threaded portion is through all coming out by the lathe car, promptly carry out turning processing by lathe tool 2, this kind processing mode needs car to fall many clouts, serious waste raw material, and the turning time is long, waste process time and cost of labor, inefficiency, the tooth bar of producing has the long weak point that has, and is difficult to control, and product quality can not be effectively guaranteed.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide the bolt toothed bar mould of the good product quality of a kind of economical with materials, high efficiency, production.
The present invention is achieved through the following technical solutions:
A kind of bolt toothed bar mould is characterized in that, comprises a body, and it has two end faces, and a side of heart die cavity also is provided with calibrating strap therein.
Above-mentioned body is made up of die sleeve and core rod, and die sleeve is positioned at the core rod periphery, and presses together with it, forms the die cavity of body in the middle of the core rod.
The invention has the beneficial effects as follows: the present invention can be with the tooth bar one-shot forming of bolt, the tooth path portion of frustrating that forms out like this needs the part that lathe peels off can be by squeezing the elongation of rising to reach the size of product requirement originally, not only raw material have been saved but also saved man-hour and cost, improve operating efficiency and production capacity, and can effectively control product quality.
Description of drawings
Fig. 1 is a conventional bolt tooth bar processing mode schematic diagram;
Fig. 2 is the structural scheme of mechanism of one embodiment of the invention.
Main Reference numeral implication is among the figure:
1, bolt 2, lathe tool 3, die sleeve 4, core rod 5, calibrating strap
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 2 is the structural scheme of mechanism of one embodiment of the invention.
As shown in Figure 2: bolt toothed bar mould, comprise a body, it has two end faces, and a side of heart die cavity also is provided with calibrating strap 5 therein, and body is made up of die sleeve 3 and core rod 4, and die sleeve 3 is positioned at core rod 4 peripheries, and press together with it, form the die cavities of bodies in the middle of the core rod 4.
The course of work of the present invention is: at first bolt 1 is fixed on the body die cavity under, and tooth bar direction upwards, then, the stamping machine action, the drive body moves downward, die cavity in the middle of the core rod 4 is done punching press to the bar of bolt through part, and can control the tooth pole length of all size processed product by the stroke of control board, because the diameter of body die cavity is less than the original bar footpath of processed product, so the part that bolt threading footpath needs lathe to peel off originally can be by squeezing the elongation of rising to reach the size of product requirement, again because body center one side is provided with calibrating strap 5, therefore the one-shot forming of tooth bar can be produced, very quick and convenient, not only saved raw material, man-hour and cost have also guaranteed the quality of product.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
Claims (2)
1. a bolt toothed bar mould is characterized in that, comprises a body, and it has two end faces, and a side of heart die cavity also is provided with calibrating strap therein.
2. bolt toothed bar mould according to claim 1 is characterized in that above-mentioned body is made up of die sleeve and core rod, and die sleeve is positioned at the core rod periphery, and presses together with it, forms the die cavity of body in the middle of the core rod.
