Abstract

The utility model relates to a structure of a roller wheel feeder, wherein a feeding roller wheel is arranged in a machine body, and a material clamping roller wheel is arranged in an adjusting base which is pivoted in the machine body by an eccentric shaft to enable the material clamping roller wheel to contact the feeding roller wheel. The adjusting base adjusts the elastic force from the material clamping roller wheel which presses the clamping and sending stamping piece of the feeding roller. A loosing material mechanism arranged in the machine body can support the adjusting base and the clamping material roller wheel to lift the feeding roller wheel off, making the stamping piece in the free state. A digital control power device directly driving the feeding roller wheel to rotate makes the feeding roller wheel and the clamping and sending stamping piece of the clamping material roller wheel feed materials through adjusting the elastic pressing and clamping force from the clamping material roller wheel and the feeding roller.

Description

The feeding machine with rolling wheel structure

Technical field

The utility model relates to a kind of feeding machine with rolling wheel structure of punch device, refers to especially press and carry the feeding machine with rolling wheel structure that the punch die stamp is sent in the shape punching secretly with the direct transmission of numerical control dynamic equipment.

Background technology

As Figure 1-3, known feeding machine with rolling wheel is that a hinged crank B2 rotates with transmission between the hinged connecting rod B1 of feeding roller A rotating shaft A1 and punch press bent axle B, the feeding roller A top hinged one material folding roller C that can swing, make with the concentric driving gear A2 engaged transmission that is connected of feeding roller A with the concentric driven gear C1 that is connected with of material folding roller C and make its reversed turning, making its pressure touch feeding roller A with a spring D compression clamp material roller C that can adjust degree of tightness makes banded punching E off and on to the feeding of punch die direction, and in the feeding because the inertia motion of brake F damping feeding roller A, when being fed to the precalculated position punch press loose metal device B3 in good time the loose metal bar G of compressing feeding machine with rolling wheel make punch die expect that surely pin locatees punching for stamp exactly to mention material folding roller C; Yet, because during the punching E of stamp different-thickness, when adjustment material folding roller C pressure is touched the gap of feeding roller A, have different engagement backlash with making between driving gear A2 and driven gear C1, and have influence on the instantaneity of its transmission, make feeding roller A and material folding roller C in starting with asynchronous material folding running can take place when stopping, and during driving gear A2 engagement driven gear C1 since the depth of engagement of clamping different-thickness punching E can change, thereby limited the thickness range that pinches punching E; In addition, brake F can increase the damping state of transmission and accelerate abrasion easily; Moreover, the mechanical transmission of punch press bent axle B will because of wear and tear loosening transposition or adjust complicated and difficult accurately, make the adjustment of transmission swivel feeding to carry out by veteran operating personnel; So, the automatic control accuracy of mechanical device for now with following inevitable development trend.

Summary of the invention

The purpose of this utility model provides a kind of feeding machine with rolling wheel structure, with the directly accurate transmission feeding element feeding of numerical control dynamic equipment, and can not influence normal feeding when adjusting the thickness of pressing the folder punching.

Another purpose of the utility model provides a kind of feeding machine with rolling wheel structure, makes to pinch the transmission form that material is not subject to actuated element, and bigger clamping punching thickness range can be provided.

The utility model purpose again provides a kind of feeding machine with rolling wheel structure, and the transmission of numerical control constitutes can make the Numerical Control of punch device more simple and easy to do, makes the quality that improves the stamp product and increases competitiveness.

The utility model purpose again provides a kind of feeding machine with rolling wheel structure, constitutes direct transmission by the numerical control transmission, and need not the user with the rotatory inertia motion of brake device damping feeding at any time and material folding element, cause the feeding error to avoid wearing and tearing take place.

The technical solution of the utility model is:

A kind of feeding machine with rolling wheel structure comprises:

One body, contiguous exit side top, two side respectively is provided with a bolt;

One feeding roller is arranged in the body, and body is stretched out in its rotating shaft;

One adjusts seat, places an eccentric shaft and is arranged on feed side in the body, and body two bolts respectively revolve establishes a nut, respectively places a spring between nut and adjustment seat;

One material folding roller is arranged on and adjusts in the seat and feeding roller clamping punching charging;

One loose metal mechanism, its loose metal rotating shaft is arranged on contiguous body exit side;

One numerical control dynamic equipment is arranged on body below, directly transmits the rotation of feeding roller with belt pulley set, makes the pressure folder friction between feeding roller and material folding roller and reverse rotation pinches the punching charging.
