Abstract
The invention belongs to the field of material preparation and processing and relates to a novel method for preparing a small rhombic hole in metal. According to the process, a small rhombic hole metal piece is obtained by solidifying and cooling metal liquid in a cavity and then pulling out a hole core which is customized according to the characteristics of the geometric dimensions and the arrangement position of the rhombic hole of the small rhombic hole metal piece and the thickness of a metal matrix. The diameter of an inscribed circle of the prepared rhombic hole is greater than 0.3mm, and the thickness of the metal piece is 1-800mm. The novel method for preparing the small rhombic hole metal piece with certain thickness is easy to operate, short in period, low in cost and easy to industrialize, and has wide development prospect in preparation of small rhombic holes in metal.
Description
Technical field
The present invention relates to small diamond hole novel preparation method in metal, belong to material preparation and fabrication field.
Background technology
Nowadays, scientific and technological and industrial continuous progress makes some metallic elements with himself characteristic arise at the historic moment.Certain thickness metalwork processes rhombus micro hole and also come its row having.But along with metallic element is progressively towards the continuous change of microminiaturization, new requirement is proposed to the processing technology of this type of metalwork of tradition.All the time, the method overwhelming majority of processing this type of metalwork is mechanical processing method, and this not only has higher requirement but also the size in hole that processes also to limit to some extent to process equipment, and its process-cycle also becomes problem simultaneously.For reported one routine profiled holes: the people such as Yu Zuyuan are adopted as spark technology and process a circumscribed circle diameter on a metal plate when being about the irregularly-shaped hole of 0.1mm, and the fastest processing duration also wants 10.4min.Well imagine, certain thickness sheet metal is processed diamond hole there is the longer process-cycle too.Therefore the metalwork preparation method finding a kind of production of more economical and efficient to have certain thickness diamond hole has become processing industry comparatively one of active demand instantly.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides small diamond hole novel preparation method in metal, this method solving the problem of processing with diamond hole metalwork and the problem of process-cycle length thereof.Especially the diamond hole problem that inscribed circle diameter is less than 10mm is processed.
For achieving the above object, the present invention is by the following technical solutions:
Its operating procedure is as follows:
(1) choose hole core crab material, be processed into rhombus, apply graphite paint thereon;
(2) Kong Xin after (1) step process is fixed in cast die cavity and prepares cast;
(3) pour in die cavity by molten metal bath, after molten metal solidifies, namely extraction hole core obtains small diamond hole metalwork.
Hole core crab material is the material that physical deformation does not occur under high temperature (the above temperature of metallic matrix fusing point) condition; Kong Xin is the rhombus iron staff or the stainless steel bar that scribble graphite paint.Especially, can save if hole core crab material is graphite rod the step applying graphite paint.Graphite paint thickness should be even, is generally 0.04 ~ 0.1mm.
Molten metal can be: the molten metal bath of one or more metal or alloy of aluminium, aluminium alloy, magnesium, magnesium alloy, tin, ashbury metal, zinc, kirsite, iron and carbon wellability difference.
Superiority of the present invention there are provided small diamond hole novel preparation method in a kind of metal, solves to have certain thickness metalwork and be processed to the large problem of difficulty of processing during small diamond hole.The inscribed circle diameter of small diamond hole can at more than 0.3mm, and metalwork thickness can 1 ~ 800mm.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Fig. 2 is small diamond hole metalwork sample.
Detailed description of the invention
With the aluminum component with small diamond hole for specific embodiment:
(1) choose iron staff as hole core crab material, will rhombus be processed into.Processing dimension: inscribed circle diameter is 0.3mm, adjacent both sides angle is 60 °.By the hole core crab coating graphite paint after processing, dry for standby;
(3) Kong Xin handled well is fixed in cast die cavity and prepares cast;
(4) molten metal bath is poured into die cavity, after molten metal solidifies, namely extraction hole core obtains small diamond hole metalwork, as shown in Figure 2.
Hole core crab material is iron staff, and graphite paint thickness is 0.1mm.
Molten metal is aluminium liquid.
Hole core is directly extracted from metallic matrix, and the Kong Xin after extracting still has can operating condition, reusable.
More than for the suitability for industrialized production of product of the present invention, extensively popularization and application provide advantage.Because hole core crab material has processing controllability, can customize according to demand, thus the small diamond hole metalwork that obtained a kind of inscribed circle diameter, adjacent both sides angle, arrangement position, metallic matrix thickness are controlled, it is suitable for answers scope very extensive.Mention that content this process visible is very simple, convenient easy to operate by above-mentioned, in process of production pollution-free, without the three wastes, do not cause the harm to environment.
