基于HDPEPVC 塑料管材无屑切割机结构设计

摘要

通过对国内外塑料管材机械生产线的研究分析，确定了无屑切割机做为本课题的主要设计内容。无屑切割机用于塑料管材的定长切割，在切割过程中机架上的移动台可以沿着管材挤出方向移动，并保持与管材的同步进给速度。在切割机的前部装有托轮装置，托轮起到支撑和导向的作用，针对不同管径时要予以调节。当翻料架上的行程开关或编码器发出切割信号后，机器夹紧装置上的夹紧控制装置夹牢管材，使管材在切割过程中相对固定，夹紧装置为夹紧块哈夫夹紧，在切割不同规格的管材时，调换相对应的哈夫块。

切割工作指令的实现由电机通过V带传动，而刀片的切削进给由气缸活塞杆缓缓推进而进行的，气缸推力的大小可由气缸的调节阀调节。刀片的无屑切割进给由移动盘和左右移动架来完成的，其中筒轴由轴承支承和定位，所以旋转中心不变使切割机切割管材端面平整，尺寸规范。进刀深度由气缸导向杆旁边的限位调节丝杆调节控制。不同规格的厚度管材，调节丝杆的调节量大小不同。

设计过程中查阅了大量国内外的相关资料，所做的设计运用所学的所有专业课程。下文主要阐述塑料管材无屑切割机总体结构设计。

切割机设计主要包括，带传动机构、夹紧机构、切割机构、切屑工作台移动导轨、机架设计。

Abstract

Through to the domestic and foreign plastics tubing mechanical production line research analysis, had determined the non- filings cutter does for this topic main design content. The non-filings cutter uses in the plastic tubing to decide long cuts, in cuts process rack from the movingplation to be allowed to squeeze out the traverse along the tubing, and the maintenance and tubing synchronization enters for the speed. Is loaded with in the cutter front part holds a turn of equipment, holds the wheel to play the strut and the guidance role, in view of different caliber when must give to adjust. After turns material on the limit switch or the encoder sends out cuts the signal, machine clamp clamps the control equipment firm tubing, causes the tubing in to cut in the process to be relatively fixed, the clamp for clamps block Haff to clamp, when cuts the different specification the tubing, exchanges Haff block which corresponds.

Cuts the working order the realization by the electrical machinery through V belt transmission, but the bit cutting for slowly pushes by the cylinder piston rod then carries on, the air cylinder thrust for cesize may by the air cylinder regulating valve adjustment. The bit non-filings cut for by move, casing of axis which the shifting plate and about movingplation completes by bearing supporting and localization, therefore the center of rotation invariablely causes the cutter to cut the tubing end surface to be smooth, size standard. Bit the depth guides nearby the pole by the air cylinder the spacing adjustment lead screw regulating control. The different specification thickness tubing, adjusts the lead screw the adjustment quantity size to be different.

In the design process has consulted the massive domestic and foreign correlation data, does the design utilization studies all specialized curricula. As follows main elaboration plastic tubing non- filings cutter overall structural design.

The cutter design mainly includes, brings the transmission system, to cut the organization, to clamp the organization, Cutting- filings the work table moves the guide rail, the rack design.
