technical field

The utility model relates to a feeding device for stamping equipment, in particular to a general-purpose steel belt feeding device.

Background technique

In the manufacturing process of electronic products, light industrial products, etc., steel strips of different thicknesses and specifications are usually stamped into required shapes by stamping equipment. Stamping includes blanking die blanking and forming die forming. In the stamping process of stamping equipment, the feeding problem of steel strip is often involved.

The Chinese invention patent with the publication number CN207534835U discloses a vehicle panel clamping manipulator, which includes a fixed rail for providing an installation position, on which there are several manipulators for clamping sheet materials and for clamping formed parts. The clamping hand and the manipulator are evenly arranged on the fixed rail; the manipulator includes a fixed seat for connection and fixation, a horizontal guide block installed on the fixed seat, a vertical guide block connected to the horizontal guide block, and fixed on the vertical guide block. The clamping claw fixing seat on the block and the clamping claws for clamping the sheet material; the clamping hand is installed on the fixed rail and used for clamping the formed parts, and the clamping hand is installed on the fixed rail and arranged symmetrically.

At present, in the feeding mechanism of the stamping die, especially in the feeding mechanism of the metal blanking die, the steel strip is generally driven to move into the mold through the clamping method. When the clamping jaw clamps the fixed steel strip, the clamping jaw and If the upper and lower surfaces of the steel strip are in contact, the clamping pressure may be too large, which may cause deformation of the steel strip and reduce the quality of the steel strip.

Utility model content

The purpose of the utility model is to provide a universal steel strip feeding device, which has the advantage of being able to stably transport steel pipes without causing deformation of the steel strips and improving the quality of the steel strips.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:

By adopting the above technical scheme, since the two limit wheels on both sides of the steel belt are in contact with each other in the process of conveying the steel belt, the steel belt moves, thereby driving the limit wheel to rotate, and the limit wheel is mainly used to limit the forward movement of the steel belt. Material movement, to prevent the deviation of the steel belt.

Further, the top surface of the beam is symmetrically provided with threaded holes, the two ends of the fixed column are provided with external threads, one end of the fixed column is threaded with the threaded hole, and the other end of the fixed column is threaded. One end is threadedly connected with a nut for compressing a spacer wheel.

By adopting the above technical scheme, the fixed column is detachably connected to the beam through threaded connection, and the limit wheel and the fixed column are also detachably connected. When the limit wheel is damaged, the staff unscrews the nut and replaces the limit wheel That's it; when the fixed column is damaged, just unscrew the fixed column to replace it, which is convenient and quick.

Further, the side of the spacer wheel is provided with a groove for contacting the edge of the steel strip, and the surface of the groove is smooth.

By adopting the above-mentioned technical scheme, the edge of the steel strip is located and is in contact with the groove surface of the clamping groove, so that the movement of the steel strip is safely restricted, and the groove surface of the clamping groove is a smooth surface, which will not scratch the side of the steel strip.

Further, the side of the feed box facing away from the mounting plate is provided with a rectangular frame-shaped fixing frame, the fixing frame includes a round bar parallel to the first driving roller, and the middle position of the round bar is connected by rotation. The pressure wheel used to press down the steel belt.

By adopting the above technical scheme, the pinch wheel presses down on the steel belt to adjust the tension of the steel band. Since the steel band has good rigidity, and because the length of the steel band is far greater than the width, there will be no extrusion of the pinch wheel. The case of local depression.

Further, the first driven roller is covered with a cloth oil-absorbing sleeve.

By adopting the above technical scheme, the steel strip is directly fed into the feeding device after being uncoiled. Too much lubricating oil is often attached to the steel strip, and the oil-absorbing sleeve can absorb part of the lubricating oil to prevent the lubricating oil from being in contact with the air. Dust stuck in the process.

In summary, the utility model has the following beneficial effects:

1. Through the setting of the first driving roller and the second driving roller, the task of conveying the steel belt is completed, the steel belt will not receive excessive pressure, the surface will not be deformed, and the quality of the steel belt will be improved;

2. Through the setting of the rubber sleeve, the surface of the rubber sleeve is rough to increase the frictional resistance, and the rubber sleeve will not scratch the surface of the steel belt while the rubber sleeve is close to the surface of the steel belt, so as to improve the quality of the steel belt.
