Abstract

The utility model discloses shaft core structure during a kind of formed product with circular arc, wherein, including shaft core fixed block and interspersed shaping shaft core in shaft core fixed block.Shaping shaft core processing is into required shape, afterwards with linear cutter into the shape that can buckle into shaft core fixed block by lathe process.Shaping shaft core is symmetric shape, can be used twice, after a face is producing abrasion, can change a face and continue production and application.It can ensure machining accuracy, while reduce processing cost again.

Description

A kind of shaft core structure during the formed product with circular arc

Technical field

It the utility model is related to shaft core structure during a kind of workpiece shaping field, more particularly to circular arc formed product.

Background technology

Product with circular arc is in shaping, since product itself just carries certain radian, if on this basis again will be into Row shaping, will be difficult to control the formed precision of product, and also affect the radian of originaling forming product.It is above-mentioned to solve Problem, needs profiling to make forming part in shaping, but the shaft core of forming part is complicated, and there are common process technique to reach Less than required structure and required precision, and the defects of processing cost is very high.

Utility model content

In view of the above problems, the purpose of this utility model is to provide a kind of structure design mode can guarantee that band circular arc product Shaft core during shaping is easy to process, and can reach the required accuracy, possess a certain amount production property with circular arc formed product when Shaft core structure.

To achieve the above object, shaft core structure during a kind of circular arc formed product provided by the utility model, wherein, including Shaft core fixed block and the shaping shaft core interted in shaft core fixed block.Shaft core and shaft core fixed block are molded all by the arc-shaped of product Shape has done corresponding copying.Shaping shaft core processing be by lathe process into required shape, afterwards with linear cutter into The shape of shaft core fixed block can be buckled into.Shaping shaft core is symmetric shape, can be used twice, when a face is worn in production Afterwards, a face can be changed and continue production and application.Thus, shaping shaft core, which is interted, is fixed on shaft core fixed block.Make shaping axle Machining feature on core fits like a glove with the machining feature on shaft core fixed block.

The beneficial effects of the utility model be forming part it is easy to process and reduce processing cost, particularly circular arc dovetail portion Point, improve processing technology, and local not intuitive ability carries out quick-replaceable in production, is not required to carry out integral replacing, reduces production Cost.

Fig. 2 is the side structure schematic view of the utility model；

Fig. 3 is the structure diagram of utility model shaft core fixed block；

Fig. 4 is the structure diagram that utility model is molded shaft core.

Embodiment

Utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figs 1-4, shaft core structure during a kind of formed product with circular arc, including shaft core fixed block 2 and consolidate in shaft core Determine the shaping shaft core 1 interted in block 2.It is to use linear cutter afterwards into required shape by lathe process to be molded the processing of shaft core 1 Into the shape that can buckle into shaft core fixed block 2.Shaping shaft core 1 is symmetric shape, can be used twice, when a face is producing After abrasion, a face can be changed and continue production and application.

In use, being to be fixed on by the way that shaping shaft core 1 is interted on shaft core fixed block 2, shaft core fixed block 2 is then utilized Other such as screw modes are fixed in product on molded part.During formed product, under the action of exterior rotating part, Product is run along the cavity track of shaping shaft core 1, so as to complete forming action.Prevent deformation and twisted phenomena, ensure The quality of product.

Above-described is only some embodiments of the utility model.For those of ordinary skill in the art, On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to practical new The protection domain of type.

Claims (1)

1. shaft core structure during a kind of formed product with circular arc, it is characterised in that including shaft core fixed block and pass through lathe process After into required shape block-shaped shaping shaft core is fixed into shaft core can be buckled into linear cutter；The shaping shaft core is symmetrical Shape.
