Abstract

The utility model relates to a radial riveting machine and belongs to the riveting device which comprises a main machine, a hydraulic pressure system and an appliance controlling system; the main machine comprises a motor, a main axis in the piston cylinder, a lower base of the main axis, an eccentric gear axis, an inner gear ring, a sphere, a sphere riveting base and a riveting head. The oil cylinder is connected with the main machine frame to form a whole structure. When the utility model works, the hydraulic pressure system transmits the oil to the oil cylinder, the piston drives the rotating main axis to press downwards, the riveting head swings along a plum shape orbit, and then the riveting between the riveting heat and the rivet reaches the yielding point to make the riveted material flow radially through a small axis direction force. The utility model has a rational design, a compact structure, a low cost, is easy to be operated; the riveting head has a long service life; the riveting pressure is five to one hundred and fifty thousand N; the diameter of the riveting is one to forty millimeter; the roughness degree of the surface Ra is no less than three point two; and the utility model is applicable to the riveting of the steel material, the copper material and the aluminum material and has a high quality of the riveting surface.

Description

The radial rivet machine

Technical field

The utility model relates to a kind of riveting machine, and concrete is a kind of radial rivet machine.

Background technology

The riveting of people's hammer, rivet hot, punching press riveted joint are arranged in the existing riveting technology.All be to rely on axial impulsive force that the rivet distortion is riveted.This technology noise is big, labour intensity is high, inefficiency.Rivet force can't be adjusted control.Easy dilatancy in the middle of the rivet, the workpiece of being riveted damages easily, and the riveted joint rear surface is of poor quality.

Another kind of riveting process is " pendulum is rolled over riveted joint ", promptly adopts pendulum to roll over the riveting machine riveted joint.Though the riveted joint of this kind method has advantages such as noise is little, simple to operate, pollution-free, in the riveted joint process, die is rotation (960 rev/mins) at a high speed under the drive of main shaft.There is relative fricting movement moment at die contact rivet, thereby produces heat, die is heated up anneal.Lose original quenching hardness HRC58～62.The die life-span is short, and the riveted joint surface quality is poor, radial component big (needing the clamp location usually).

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of reasonable in design, easy to operate, die long service life, riveting pressure, wide, the riveted joint face quality height of riveted joint diameter range, can be suitable for the radial rivet machine of multiple material riveted joint.

The implementation of the utility model purpose is that the radial rivet machine comprises main frame 25, electrical apparatus control system 27, hydraulic system 26.Main frame partly is made of motor, main shaft, piston, oil cylinder, following part and bulb.Motor 1 is by the main shaft of guide pin bushing shaft coupling 2 tippings in mainframe 4, main shaft drives following 9 rotation of following part, be equipped with one on the following seat and in ring gear 13, make the eccentric gear axle 19 that the plum blossom track rotates, the spheroid seat 22 of ring gear, bulb part is fixed on the piston 7, eccentric gear axle 19 drive the sphere rivet set 17 that is contained in the spheroid seat 22 and on die 18, the sphere rivet set is by spring 15 and plane bearing 16 supportings.Oil cylinder and mainframe 4 are overall structure.

The utility model mainly comprises main frame, hydraulic system, electric control system three parts.Main frame 25 is to drive main shaft by motor 1 by guide pin bushing shaft coupling 2 to be rotated.Main shaft 6 is installed in the mainframe 4, under the effect of the pressure oil that hydraulic system 26 is imported, makes progress, moves downward.Main shaft 6 connects following 9 of drive by taper pin 8 and rotates.An eccentric orfice is arranged, setting-up eccentricity gear shaft 19 on the eccentric orfice on the following seat 9.Two radial thrust bearings of the eccentric gear axle 19 upper and lower companies of being equipped with 21,23.Under the transmission of main shaft, gear shaft can be made quincunx track and rotate in ring gear 13.Ring gear 13, spheroid seat 22 is fixed on the piston 7 by clamping screw.Under the drive that is bearing in eccentric gear axle 19 of sphere rivet set 17 by spring 15, make quincunx track round centre of sphere O point and rotate.It below the spring 15 plane bearing 16, plane bearing 16 can be eliminated the sphere rivet set when making quincunx track and rotate, rivet set 17, spring 15, protect relative displacement and friction between the awl cover 14, avoid spring internal stress in long-term work to eliminate, produce tired and the damage that fractures, thus the service life of improving spring.

During the utility model work, in A chamber input mainframe 4, exert pressure the main shaft drive of rotation downwards by piston with pressure oil for hydraulic system.Die 18 forms soft effective distortion by quincunx track hypocycloid operation at this moment.With less relatively axial force, make the riveted joint material in the contact area very little between die and the rivet reach yield point, make and radially flowed by the riveted joint material.Because of rivet surface head dummy forms step by step along its machine track that moves.Roll over riveting with pendulum and compare, the radial rivet method only can reach very big distortion with very little rivet force.Underload has been protected die, and its life-span is prolonged.

In the riveted joint process, self does not rotate die, the friction minimum between die and the rivet like this, thus formed the perfect surface texture of rivet.Material radially flows can prevent to produce torsional stress, thereby obtains high-quality riveted joint face and very high fatigue resistance.

The utility model is reasonable in design, compact conformation, and cost is low, and is easy to operate, the die long service life, riveting pressure 5-150 thousand newton, riveted joint diameter phi 1-φ 40mm, surface roughness Ra 〉=3.2 are suitable for the riveted joint of multiple materials such as steel, copper, aluminium matter, riveted joint face quality height.Shape after the riveted joint can be shapes such as flat shape, round end, flanging, interior reducing.
