Automatic punching integrated unit for four intersecting lines at two ends of circular pipes

Abstract

The invention relates to an automatic punching integrated unit for four intersecting lines at two ends of circular pipes and belongs to the technical field of automation, and automatic punching of theintersecting lines of the circular pipes which are perpendicularly intersected is achieved. The automatic punching integrated unit comprises a stock bin frame, four station moving hydraulic punchingunits, a material transferring part, a finished product stock bin, a hydraulic station, a CNC control center and the like. The automatic punching integrated unit mainly comprises air cylinders, gears,racks, a material guide mechanism, buffer plates, a material jacking mechanism, four station machining mechanisms, a hydraulic control workstation, a linear guide way, a servo motor, a ball screw, a180-degree turnover mechanism, a circular pipe punching die, a discharge guide rail, a finished product stock bin and the CNC control center. The automatic punching integrated unit is designed for modern agricultural development and integrates multiple working procedures of feeding, punching and discharging. The automatic punching integrated unit is good in consistence of processed products, highin precision, easy to operate, high in automation degree and machining and producing efficiency and capable of adapting to machining of circular pipes with various pipe diameters and lengths.

Description

technical field [0001] The invention relates to the field of industrial equipment, in particular to an automatic intersecting line punching device, in particular to an integrated unit for automatic punching of four intersecting lines at both ends of a round tube. Background technique [0002] The intersecting line is actually the connecting part between two intersecting pipes. In order to make the two pipes can be completely welded together, an opening must be opened on each of the two intersecting pipes. Through-line punching is a common process method for connecting branch pipes and main pipes of round pipes. [0003] When the current intersecting line is punched, many problems will be encountered: (1) Manual punching is flexible and convenient, but the quality of manual punching is poor, the size error is large, the follow-up processing workload is large, and the production efficiency is low; (2) Semi-automatic punching Cutting machines are mostly started with buttons an...

Problems solved by technology

[0003] When the current intersecting line is punched, many problems will be encountered: (1) Manual punching is flexible and convenient, but the quality of manual punching is poor, the size error is large, the follow-up processing workload is large, and the production efficiency is low; (2) Semi-automatic punching Cutting machines are mostly started with buttons and pedals, punching once, and moving once at a fixed length manually. Continuous punching cannot be completed, and it requires the cooperation of multiple people to complete the operation, which is labor-intensive and low-precision; (3) CNC flame and plasma cutting , the former has large cutting deformation, low cutting precision, low cutting speed, long cutting warm-up time and long perforation time, and it is difficult to adapt to the needs of fully automatic operation. Plasma cutting has a wide cutting range, fast cutting speed, and high work efficiency. characteristics, but it requires a large plasma power source, the cost is high, and it is easy to appear V-shaped when cutting thick-walled tubes

In short, the processing accuracy and processing efficiency of these two cutting methods are relatively low, which cannot meet the actual production requirements.

[0004] At present, all walks of life are based on modular, combined, standardized, and general-purpose manufacturing concepts, making the application of automation equipment increasingly widespread, but the construction of intersecting line blanking automation units cannot meet the needs of market development.
