Abstract

The invention discloses an irregular bar machining process. The irregular bar machining process comprises the following process steps of first-time solid solution, first-time sand blasting, first-time cold drawing, second-time solid solution, second-time sand blasting, second-time cold drawing, third-time solid solution, acid pickling, third-time sand blasting, finished product drawing, fixed-length cutting, straightening, polishing, checkout and packaging and warehousing. An original acid pickling step is omitted after semi-finished product cold drawing, the original effect is achieved by changing sand blasting process parameters and sand shot size. By the adoption of omission of the partial acid pickling step, the production cost can be saved, and environmental protection is facilitated.

S2: sandblast for the first time, by sand-blasting machine, the blank after fining away is carried out to blasting treatment, the frequency of sand-blasting machine is 45HZ, and sandblast speed is 5 ms/min, and sand ball diameter is 0.6mm;
S3: cold-draw for the first time, cold-draw is of a size of S52.94, and cold-draw speed is 1.5 ms/min;
S4: solid solution for the second time, solid solubility temperature is 1000 DEG C, solution time 45 minutes;
S5: sandblast for the second time, the blank by sand-blasting machine after to solid solution for the second time carries out blasting treatment, and the frequency of sand-blasting machine is 45HZ, and sandblast speed is 5 ms/min, and sand ball diameter is 0.6mm;
S6: cold-draw for the second time, cold-draw is of a size of S46.28, and cold-draw speed is 1.5 ms/min;
S7: solid solution for the third time, solid solubility temperature is 1000 DEG C, solution time 45 minutes;
S8: pickling, pickling temperature is 40-70 DEG C, pickling time is 5-15min;
S9: sandblast for the third time, the semi-finished product by sand-blasting machine after to pickling carry out blasting treatment, and the frequency of sand-blasting machine is 25HZ, and sandblast speed is 10 ms/min, and sand ball diameter is 0.6mm;
S10: finished product is taken out, carries out finished product to the semi-finished product after blasting treatment for the third time and takes out processing, and finished product is taken out and is of a size of S44.37, and cold-draw speed is 1.5 ms/min;
S11: customized cut-off, aligning, polishing, inspection, packaging warehouse-in.
As preferably, in step S8, pickle is that concentration is 98% sulfuric acid.
Advantage of the present invention and beneficial effect are: by cancel original pickling after semi-finished product cold-draw; by the change of the change to blasting craft parameter and sand ball size; then reach original effect; the part acid pickling step of cancelling not only can save production cost, and is conducive to environmental protection.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
A kind of special-shaped excellent processing technology, comprises following processing step:
S1: solid solution for the first time, choose the bar that radius is R70mm, solid solubility temperature is 1000 DEG C, and solution time 45 minutes carries out casting skin aligning after solid solution, aligning speed is 2 ms/min, after aligning, carry out peeling, barking speed is 3 ms/min, after peeling, fines away, sharpening length is 180mm, is of a size of R49mm after sharpening;
S2: sandblast for the first time, by sand-blasting machine, the blank after fining away is carried out to blasting treatment, the frequency of sand-blasting machine is 45HZ, and sandblast speed is 5 ms/min, and sand ball diameter is 0.6mm;
S3: cold-draw for the first time, cold-draw is of a size of S52.94, and cold-draw speed is 1.5 ms/min;
S4: solid solution for the second time, solid solubility temperature is 1000 DEG C, solution time 45 minutes;
S5: sandblast for the second time, the blank by sand-blasting machine after to solid solution for the second time carries out blasting treatment, and the frequency of sand-blasting machine is 45HZ, and sandblast speed is 5 ms/min, and sand ball diameter is 0.6mm;
S6: cold-draw for the second time, cold-draw is of a size of S46.28, and cold-draw speed is 1.5 ms/min;
