1.2. continuously extruding and molding link
The continuously extruded grain structure that forms cross sectional shape, surface quality and the hope of arts demand afterwards of blank process with up casting.These intermediates of this moment are organized the tiny orderly forging tissue that is rendered as fully in the metallography through the crystal inside of its material after the violent distortion, and are the hot-working softening forms after the tempering again.
1.3. the drawing link is strengthened and the typing link
The intermediate of coming out pressurizeing is continuously carried out drawing processing, make it through necessary cold conditions stretcher strain, thereby improve intensity and toughness index and other physical performance index of these goods, and further improved goods geometric accuracy and surface quality, made it reach good comprehensive quality index.The product of this moment is through the more tiny cold-work strengthening state of grain size after the cold stretch distortion.
2. correlation technique
2.1. up-drawing method casting copper (aluminium) bar
Irrelevant with this patent, so repeat no more.
2.2. it is continuously extruded
Continuously extruded, claim Kang Feng extruding (Conform Extrusion) again, a large amount of in recent years extruding bases that is used for copper (aluminium) row, bar and part profiled-cross-section section bar has almost completely replaced the billet production method of traditional copper (aluminium) row, copper bar and part sections with small cross-section.It is continuously extruded that this technology is that copper (aluminium) bar of coil shape that the up casting method is produced carries out, and forms preliminary flat row, bar and profile shapes, and these all are intermediate products; This method is the most effectively blank-making method of generally acknowledging at present.
These continuously extruded intermediate products that come out also need could form final products through follow-up drawing processing.
2.3. the drawing mode that traditional single is interrupted
At present, after continuously extruded, be used for copper (aluminium) row, copper (aluminium) bar, and the special-shaped small bore copper of part (aluminium) section bar drawing processing all is the chain drawbench that falls behind, the hydraulic drawbench of the perhaps relatively backward long stroke of single cylinder carries out drawing.The drawing mode that these singles are interrupted is a kind of traditional old drawing mode, and the feature of this Hubbing method and shortcoming are:
1) stretching interruption is carried out.All the original very long material cut-out of coiling to be become short sectional vertical bar material before each drawing, just can drawing.
2) in the whole process of drawing, the head that draw carriage can only the clamping goods carries out drawing; Because clamp has tooth, in the drawing process of every section goods, all can crush the head of goods, thereby make that the section of being held becomes waste material;
3) drawing length depends on the drawing haul distance with drawbench, is the drawing of finite length, and efficient is low;
4) each section goods all will be made head before drawing, and lumber recovery is low, and efficient is low;
5) carry out fixed ruler cutting again after drawing is over;
6) drawbench takies very big floor area, operation is disperseed, and the workshop is arranged in disorder;
7) workshop is in disorder, automaticity is low, work situation and operating condition are poor.
2.4. the hydraulic continuous drawing of invention indication
Here said hydraulic continuous drawing is for the single that alternate manner is realized is interrupted drawing mode.Hydraulic continuous drawing is meant in the process of normal drawing, with clamp or embrace pincers or method that grip block carries out drawing from the lateral surface clamping goods of goods.
Before this, continuous drawing technique mainly is to adopt mechanical continuous drawing machine and the cooling red copper coil of pipes of technology processing, and some steel pipe's production.
The characteristics of this Hubbing method and advantage are as follows:
1) two dollies are by hydraulic-driven, and alternately back and forth movement carries out drawing;
2) clamp or armful pincers or grip block clamping goods lateral surface are not only to add the head of holding goods;
3) this clamping is to not damage of product surface;
4) goods are advancing continuously in the drawing process;
5) goods length that can drawing and clamp, it doesn't matter to embrace the stroke of pincers, grip block;
6) can draw the goods of random length;
7) the production efficiency height, become a useful person high, quality of item is good;
8) it is few to take floor area, and neat appearance is arranged in the workshop, has high automaticity;
9) has good work operating environment.
