Abstract
The invention relates to a process technique for processing a stainless steel oil pipe, which mainly comprises the following processing steps of: (1) according to assembling requirements of products, drilling a bottom hole and performing tapping and face milling according to drawing dimensional requirements in advance on an oil pipe joint, and simultaneously preparing a screwed joint matched with the bottom hole; (2) assembling, namely screwing the screwed joint into the oil pipe joint so as to obtain an oil pipe assembly; (3) putting the oil pipe assembly on a die-casting mould, and precisely positioning the oil pipe assembly with a limiting insert on a die to ensure the true position of the oil pipe joint and the distance size of the end face of the joint after die casting; and (4) demounting the screwed joint which can be recycled after finishing die casting molding to obtain a finished product oil pipe. Compared with the prior art, the process technique has the following advantages that: firstly, scrap irons are effectively prevented from falling into the oil pipe during processing, and the cleanliness and the flow accuracy of the oil pipe are high; secondly, the rate of finished products is high, and the productivity is increased by 59 percent under the condition of not increasing production facilities; and thirdly, the input of the production facilities can be reduced.
Description
Technical field:
The present invention relates to a kind of process technique for processing stainless steel oil pipe.
Background technology:
The technological process of existing processing oil pipe is: oil pipe is put on the compression mod, by with mould on the spacing location of inserting, earlier cut saw along the oil pipe end face after the die casting with cutting machine, mill flat oil pipe both ends of the surface then, brill is attacked the M12/16 screw thread.The advantage of this technology: can accurately guarantee the oil pipe face size, but also have following shortcoming: the one, the oil pipe flow is defective, adds to avoid man-hour iron filings to fall in the oil pipe, causes the cleannes severe overweight, can't satisfy client's needs; The 2nd, cause production capacity low owing to yield rate is low, can't satisfy client's demand; The 3rd, production cost is higher: for satisfying client's a maximum demand, need to increase cutting oil pipe special plane, jetting machine, machining fixture (joining turntable) and expense such as artificial.
Summary of the invention:
Purpose of the present invention provides a kind of process technique for processing stainless steel oil pipe, and it can overcome the deficiencies in the prior art.
The present invention is achieved in that it mainly is made of following process: (1), according to the matching requirements of product, on oil connection, bore by the drawing dimensional requirement in advance and attack bottom outlet, tapping and mill face, make the nipple that cooperates with it simultaneously; (2), assembling, screw in and obtain the oil pipe assembly in the oil connection thereby be about to nipple; (3), above-mentioned oil pipe assembly is put on the compression mod, by with mould on the spacing accurately location of inserting, guarantee oil connection position degree and joint end face after the die casting apart from size; (4) die cast finishes the nipple that reusable edible is removed in the back, can obtain the finished product oil pipe.
The present invention compared with prior art has the following advantages: the one, and add and can effectively avoid man-hour iron filings to fall in the oil pipe oil pipe cleannes and flow accuracy height; The 2nd, the yield rate height can make production capacity improve 59% under the situation that production equipment does not increase; The 3rd, can reduce the input of production equipment.
The specific embodiment:
The present invention mainly is made of following process: (1), according to the matching requirements of product, on oil connection, bore by the drawing dimensional requirement in advance and attack bottom outlet, tapping and mill face, make the nipple that cooperates with it simultaneously; (2), assembling, screw in and obtain the oil pipe assembly in the oil connection thereby be about to nipple; (3), above-mentioned oil pipe assembly is put on the compression mod, by with mould on the spacing accurately location of inserting, guarantee oil connection position degree and joint end face after the die casting apart from size; (4) die cast finishes the nipple that reusable edible is removed in the back, can obtain the finished product oil pipe.
In the present embodiment, nipple has galvanizing coating, and what this galvanizing coating had suppressed at high temperature that thread surface and nipple mating surface Yin Gaowen and greasy dirt cause gets rusty, thereby guarantees the cleannes requirement of product, and effectively protection oil pipe end face is not damaged; Oil pipe internal thread active force by nipple in the casting forming process has guaranteed thread form, thereby reaches the purpose that is directly realized processing by extrusion process.
Claims (2)
1. process technique for processing stainless steel oil pipe, it is characterized in that it mainly is made of following process: 1) according to the matching requirements of product, on oil connection, bore by the drawing dimensional requirement in advance and attack bottom outlet, tapping and mill face, make the nipple that cooperates with it simultaneously; 2) assembling screws in the interior oil pipe assembly that obtains of oil connection thereby be about to nipple; 3) above-mentioned oil pipe assembly is put on the compression mod, by with mould on the spacing accurately location of inserting, guarantee oil connection position degree and oil connection end face after the die casting apart from size; 4) die cast finishes the nipple that reusable edible is removed in the back, can obtain the finished product oil pipe.
2. a kind of process technique for processing stainless steel oil pipe according to claim 1 is characterized in that nipple has galvanizing coating.
