Description
Technical Field
The utility model relates to a cold heading machine equipment field especially relates to a cold heading machine ejection mechanism with abrasionproof decreases gyro wheel.
Background
The existing cold header equipment can extrude a cold header workpiece into a forming concave surface on a movable mould block or a fixed mould block of the cold header equipment when in work, so that an ejection mechanism is usually arranged in a cold header mould and is used for ejecting a cold header part clamped at a forming part, and the existing common ejection mechanism is used for ejecting a right-angle rocker arm downwards to obtain a swinging track of the other rocker arm to the horizontal direction so as to push an ejector rod.
Disclosure of Invention
In order to solve the problem, the utility model provides a structure is succinct and possess the cold heading machine ejection mechanism who is equipped with the abrasionproof and decreases the gyro wheel that decreases the function.
In order to reach above-mentioned purpose, the utility model discloses a cold heading machine ejection mechanism with abrasionproof decreases gyro wheel, include the module that moves that is linear reciprocating motion at the horizontal direction, the front portion of moving the module be equipped with the ejector pin that the level set up, move the module and be equipped with a right angle rocking arm in the top of supporting of ejector pin, the ejector pin is supported to a rocking arm end of right angle rocking arm, the terminal upper portion of another rocking arm of right angle rocking arm is equipped with a gyro wheel, the rear portion of moving the module be equipped with the straight angle rocking arm, the middle part hinged joint of straight angle rocking arm is on moving the module, the front end of straight angle rocking arm is provided with the axial decurrent screw rod, the lower terminal surface of screw rod pass straight angle rocking arm roof pressure gyro wheel. The advantage of using the gyro wheel structure is that the gyro wheel can turn into rolling friction with the pressure impact of screw rod to reduce wearing and tearing, simultaneously, the gyro wheel can be replaced after long-time use produces wearing and tearing, need not to change whole right angle rocking arm work piece, saves the cost.
The further proposal is that the screw rod is connected with the straight angle rocker arm through a connecting block fixedly connected with the front end of the straight angle rocker arm. Through the setting of connecting block, with screw rod and straight angle rocking arm separation, convenient installation screw rod, adjusting screw rod's extension length also can replace not unidimensional connecting block simultaneously and adjust its distance that stretches out the straight angle rocking arm to the cooperation position between adjusting screw rod and the gyro wheel.
The right-angle rocker is characterized in that a rocker counter bore is arranged below the roller, a spring hole is formed in the movable module at the position corresponding to the rocker counter bore, and a return spring is arranged between the rocker counter bore and the spring hole. The reset spring is used for performing upward elastic reset on the pressed right-angle rocker arm, and the other function of the reset spring is that the screw is always kept tightly attached to the roller to continuously apply pressure to the roller when the screw is pressed down.
The screw rod is in threaded connection with the connecting block, the screw rod penetrates through the connecting block from bottom to top, and the screw rod is connected with an adjusting locking nut above the connecting block. The downward extending distance of the screw rod can be adjusted by adjusting the locking nut, so that the position of the screw rod in contact with the roller is changed when the screw rod is pressed downwards, and then the ejection distance of the ejection end of the right-angle rocker arm is finely adjusted.
In a further scheme, a convex part is arranged on the contact surface of the right-angle rocker arm and the ejector rod. The bulge has avoided the whole terminal surface of rocking arm of right angle rocking arm and movable mould piece contact on the one hand, and on the other hand has also played the effect of reserving the wearing and tearing volume.
The utility model discloses a cold heading machine ejection mechanism with abrasionproof decreases gyro wheel, the contact surface with right angle rocking arm and bolt has been replaced into the gyro wheel structure on the basis of original mechanism, when the bolt pushes down under the effect of right angle rocking arm, the gyro wheel is pushed down to the bolt, under the pressure of bolt, slight roll can take place for the gyro wheel, the frictional force part between bolt and right angle rocking arm is absorbed by the gyro wheel in the original structure, some is then turned into the rolling force of gyro wheel, the effect of abrasionproof decreases has been played, thereby effectual increase working life. In addition, a return spring is arranged between the lower part of the roller part of the right-angle rocker arm and the upper end surface of the corresponding movable module, and the return spring pushes the pressed right-angle rocker arm up again to reset the mechanism, so that the next stroke is prepared.
