Description
Technical field
The invention belongs to oil exploration equipment technical field, and in particular to a kind of oil drill rocker machining manufacture.
Background technology
Oil drill rocker be for the very part of core in Petroleum Production machinery, oil drill rocker mainly by by tool joint and
Drill pipe body forms, and it is processed and the quality of manufacture, security during by the quality of oil exploration equipment and exploitation have very
Big influence, wherein joint of petroleum drill rod are the important connection members of oil drill rocker, are had to mechanical performance and smoothness strict
It is required that.Because joint of petroleum drill rod size is elongated, and it is hollow structure, is shaped in forging process and raising precision difficulty is more.
For existing joint of petroleum drill rod when forging, difficult forming, precision is not high, passes through machining according to high performance material
The problem of method is molded, but this method is there is wasting raw material, and cost is high.
The content of the invention
It is an object of the invention to provide a kind of oil drill rocker machining manufacture, can overcome in the prior art, machining accuracy
The problem of not high and cost is huge.
The technical solution adopted by the present invention is a kind of oil drill rocker machining manufacture, specifically to implement according to following steps：
Step 1, pre-treatment and preheating；
Step 2, the material after being preheated in step 1 is subjected to jumping-up processing,
Step 3, the workpiece after jumping-up processing in step 2 is subjected to Compound Extrusion and necking,
Step 4, the workpiece after step 3 is extruded carries out copper plating treatment,
Step 5, post-processed.
It is of the invention to be further characterized in that,
Described step 1 concretely comprises the following steps：
Step 1.1, polishing processing is carried out to the surface of blank, removes the oxide layer on its surface；Or also can be by using
The mode of pickling carries out removing surface；
Step 1.2, blank is preheated, preheating temperature is 1000 DEG C~1300 DEG C.
Step 3 concretely comprises the following steps：
Workpiece after being handled in step 2 is put into cavity plate, then controls extruding punch common with cavity plate after moving downward
Effect carries out extrusion process；When being handled, forcing press impulse stroke is 3~5 times of workpiece height.
Described forcing press uses 1250 t hydraulic press.200 millimeters of diameter, 60 millimeters of bar portion endoporus, forging height can be produced
The joint of petroleum drill rod of 450 millimeters of degree and its following size.
Described step 4 is specially：Workpiece after being handled in step 3 is put into copper-bath electroplating bath, to joint
Screw thread and sealing surface position plate fine copper.
Step 5 is tempered specifically, the joint after copper facing is put into tempering furnace, and it is 680 DEG C to control temperature, is protected
Warm 115min, then hang out and be water-cooled to normal temperature.
The beneficial effects of the invention are as follows：Utilize tempering this high-temperature process after Compound Extrusion processing and copper facing so that
The mechanical performance of workpiece is lifted well.So that product durability when in use and intensity and toughness have good journey
Degree.
