Abstract
The utility model relates to a multi-channel irregular copper bar extrusion die. The multi-channel irregular copper bar extrusion die is characterized by comprising a main body; a multi-groove irregular hole is formed in the middle of the main body; a guiding channel for guiding an oxygen-free copper rod is arranged in an inlet of the multi-groove irregular hole in the main body; the guiding channel is communicated with the multi-groove irregular hole; and the section of the multi-groove irregular hole is comb-shaped. The multi-channel irregular copper bar extrusion die has the advantages of easiness in production, short production period, high production efficiency and material utilization rate, and low in rejection rate.
Description
Technical field
The utility model relates to a kind of multiple-grooved non-conventional copper bar extrusion die.
Background technology
The complicated structure of multiple-grooved copper bar adopts the method production of machine cut processing at present, and there is following defective in it:
1, difficulty of processing is large, and the process-cycle is long, and efficient is low; Also because of the complex structure of multiple-grooved copper bar, machining is shaped needs accurate equipment and numerous and diverse manufacturing procedure.
2, stock utilization is low, and percent defective is high, and its stock utilization is lower than 80%, percent defective approximately 10%.
Summary of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and a kind of easy production is provided, and the process-cycle is short, and production efficiency is high, the multiple-grooved non-conventional copper bar extrusion die that stock utilization is high and percent defective is low.
In order to achieve the above object, the utility model is to realize like this, it is a kind of multiple-grooved non-conventional copper bar extrusion die, it is characterized in that comprising parent, be provided with the multiple-grooved profiled holes in the centre of described parent, the porch that is positioned at the multiple-grooved profiled holes in parent is provided with the introduction channel that can import oxygen-free copper bar, and described introduction channel is communicated with the multiple-grooved profiled holes, and the section of described multiple-grooved profiled holes is pectination.
Also be provided with high strength, high pressure resistant and resistant to elevated temperatures inserting at the center of described parent, described multiple-grooved profiled holes is located at the centre of inserting.
The entrance of described introduction channel is large, goes out youngly, and the entrance of the outlet of introduction channel and multiple-grooved profiled holes is corresponding and be communicated with.
The utility model compared with prior art has following advantage to be:
1, stock utilization is more than 90%, because the extrusion blank for preparing by extrusion die, through a drawing of follow-up finished product mould, the direct forming product need not any machine cut processing, easily produces;
2, obtain high-accuracy size and baroque product, because the thinnest interface dimensions is less than 1mm,
Dimensional tolerance can be controlled in 0.05mm, and in form and position tolerance 0.05mm, percent defective is low;
3, shorten the production cycle, only need several hours, production efficiency is high.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The below describes embodiment of the present utility model in detail, and the example of described embodiment is shown in the drawings, in figure from start to finish same or similar label represent same or similar element or the element with identical or similar functions.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
As shown in Fig. 1 to 2, it is a kind of multiple-grooved non-conventional copper bar extrusion die, comprise parent 1, be provided with multiple-grooved profiled holes 4 in the centre of described parent 1, the porch that is positioned at multiple-grooved profiled holes 4 in parent 1 is provided with the introduction channel 3 that can import oxygen-free copper bar, described introduction channel 3 is communicated with multiple-grooved profiled holes 4, and the section of described multiple-grooved profiled holes 4 is pectination.In the present embodiment, the groove of described multiple-grooved profiled holes 4 is half arc.During work, provide power by continuous copper material extruder, oxygen-free copper bar is dragged in multiple-grooved profiled holes 4 by introduction channel 3, extrude extruded stock (semi-finished product blank) by extrusion die, then pass through the finished product mould drawing shaping finished product of extruded stock.
In the present embodiment, also be provided with high strength, high pressure resistant and resistant to elevated temperaturesly insert 2 at the center of described parent 1, described multiple-grooved profiled holes 4 is located at 2 the centre of inserting.2 have high strength, high pressure resistant and resistant to elevated temperatures characteristic owing to inserting, thereby guarantee extruded stock size and stable performance, extruded stock allowance is minimum, and general control is guaranteed a follow-up drawing moulding at 0.2 ~ 0.8mm, obtains high-precision product.
In the present embodiment, the entrance of described introduction channel 3 is large, goes out youngly, and the entrance of the outlet of introduction channel 3 and multiple-grooved profiled holes 4 is corresponding and be communicated with, and is convenient to like this import oxygen-free copper bar.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that do not break away from principle of the present utility model and aim can be carried out multiple variation, modification, replacement and distortion to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
