The equipment is characterized in that a spray gun which can be inserted inside the inner hole is connected with a shot peening system by a shot peening accelerated tube; while the shot peening system is connected with a drive device which realizes the reciprocating application of the system; and the system is installed on a guide rail, and the shot peening accelerated tube is intalled on a high-adjustable guide device. The equipment has the following advantages that shot peening strengthening technology is applied to harden the surface of the inner hole of an oil drill collar, and the hardening process can be adaptable on oil drill collars with different lengths, apertures, tolerances, hardness with the same equipment.
Description
Technical field
The invention belongs to the bore area hardening equipment, be specifically related to a kind of ultralong thin-hole bore superficial hardening device.
Background technology
Piece surface method for curing commonly used adopts mechanical means more, makes piece surface produce plastic deformation, can cause the Surface Machining sclerosis.Be characterized in using mechanical energy to cause the strengthening surface layer of unbalance microstructure such as superficial layer high density dislocation, subgrain fragmentation, thus reinforcing material surface strength, hardness, wearability, corrosion resistance and physical property effectively.
But the sclerosis of the surface of ultralong thin-hole bore, because its draw ratio is very big, and the bigger deviation of the common existence in endoporus aperture, so adopt traditional mechanical means, can't solve case-hardened application of force problem.
For example: stone oil drill collar, belong to the drilling well specific purpose tool, consumption is bigger.Its endoporus aperture is very little, and between Φ 50mm～Φ 80mm, and stone oil drill collar length is more than 5000mm, and there is bigger deviation in the endoporus aperture.The inner bore surface roughness of stone oil drill collar and hardness are to influence the stone oil drill collar key factor in service life.Stone oil drill collar is utilizing after the deep hole machining technology finishes stone oil drill collar endoporus processing, and its inner bore surface roughness is bigger, and hardness is lower, directly comes into operation, and can cause the quick wearing and tearing of stone oil drill collar bore area, so that whole stone oil drill collar is scrapped.And adopt traditional mechanical means, be the application of force problem that can't solve the sclerosis of stone oil drill collar bore area.
Summary of the invention
The present invention can't solve the application of force problem of ultralong thin-hole bore superficial hardening in order to solve existing traditional mechanical means, and a kind of stone oil drill collar bore area hardening equipment is provided.
The present invention adopts following technical scheme to realize:
Ultralong thin-hole bore superficial hardening device, it is characterized in that it comprises the spray gun that can stretch in the endoporus, spray gun is connected with peening system by the shot-peening accelerating tube, peening system is connected with the drive unit that drives its reciprocal utilization, peening system is installed on the guide rail, and the shot-peening accelerating tube is installed on the adjustable for height guider.
The described endoporus other end connects recovery system by negative pressure straw.
Bullet at first mixes in the mixing chamber of peening system with compressed air, and enters the shot-peening accelerating tube jointly through leading the ball pipe, and shot-peening accelerating tube front end connects spray gun.Spray gun and shot-peening accelerating tube are stretched into the stone oil drill collar endoporus jointly, and shot-peening sprays to the bore area of stone oil drill collar under the effect of air-flow.Bullet impact stone oil drill collar bore area makes it to produce pit.The drill collar bore surface produces plastic deformation and macroscopical residual stress under the effect of mechanical force, cause work hardening, thereby the hardness of drill collar bore superficial layer, intensity are improved, and reduces surface roughness.Along with the bullet repeated multiple times is impacted the drill collar bore area, its surface plastic deformation amount increases, and case hardness, intensity increase gradually.The bullet that sprays to the drill collar bore surface reclaims by recovery system, screens again, and damaged bullet is removed, and can reenter fabrication cycles by conveying device by reusable bullet.By changing stream pressure, spray technological parameters such as orientation, can effectively control the degree of depth of drill collar cementation zone.
In the course of work, workpiece is placed on the workbench of being made up of the V-type support.Workpiece maintains static, and nozzle moves with peening system.Peening system moves to workpiece under the drive of drive unit, and nozzle enters drill collar bore by guider, implements the shot-peening process.
The present invention has following beneficial effect: adopt stress peening process, the stone oil drill collar bore area is hardened, the stone oil drill collar that can require different length, different aperture, different tolerance, different hardness on same equipment carries out the bore area sclerosis.
