冲床自动送料装置设计

摘 要
冲床自动送料装置是配合冲床工作，以提高冲床的工作效率，同时减轻工人的劳动量，提高冲压工艺的自动化程度。
本设计方案的原理：动力从冲床带轮取出，通过传动轴传递给送料辊和废料卷料筒，同时完成板料的送进和废料的卷起。带轮将动力通过齿条传递给齿轮，齿轮和一个单向超越离合器相联结，只传递正向的转矩。单向超越离合器带动传动轴1转动，由轴1上的齿轮带动送料辊送料。轴1和轴2通过摩擦离合器联接，由轴2上的齿轮带动卷料筒卷起废料。卷料筒在卷起废料的过程中直径会不断增加，致使轴2的圆周速度增加，当卷料筒的卷料速度大于送料速度时，由于摩擦离合器所传递的转矩过大，摩擦片就会打滑，从而消减卷料筒的卷料速度。
送料辊分为主动辊和从动辊，从动辊是可调的。当
料送进时，拧紧从动辊两端的紧定螺钉将从动辊压下，从而压紧板料，并且通过两辊轴的摩擦力来实现板料的送进。 卷料筒是可拆卸的，当废料卷满后，卸下卷有废料的卷料筒，除去所卷废料后再安装到卷料结构上继续使用。为了提高效率，可以增加一个卷料筒，两个卷料筒交替使用。

Summary
Puncher give material device to cooperate with puncher work , in order to improve working efficiency of puncher automatically, lighten workers amount of labour, and improve the automatic degree of pressing the craft .
Principle of this design plan : Power take wheel take out from puncher, is it is it give material roller and waste material rolls of material tube to give to transmit through drive shaft, the ones that finish board material rolling with waste material at the same time are sent. Bring wheel through transmit give gear wheel by rack , gear wheel and one one-way to surmount clutch bind power, only transmit the torque turning towards. One-way to surmount clutch drive 1 drive shaft rotate , is it hand over material roller to hand over the material to drive by gear wheel of 1 axle. Axle 1 and axle 2 is bound through rubing the clutch, driven a roll of material tube to roll the waste material by the gear wheel on axle 2. Rolls of material tube diameter will increase constantly during the process of rolling waste material, is it increase to cause axle 2 circumference speed, as rolls of rolls of material , material of tube being speed heavy to when give the speed of material , rub torque that clutch transmits too big, the friction disc will skid , thus subdue the speed of a roll of material of a roll of material tube.

Sending the material roller to be divided into a initiative roller and driven roller, the driven roller is adjustable. When the board material is sent to , tighten driven roller both ends make screw is it down to pigeonhole driven roller closely, compress tightly board material , is it realize through two roller frictional force of axle board material send to to come.
A roll of material tube is detachable , after the waste material one is full, unload a roll of material tube with waste material , is it is it get to install one more material structure continue using after the rolls of waste material to remove. In order to raise the efficiency, can increase pieces of material tube , two pieces of material tube are used alternativly.
