Ingot feeding system for short stroke front loading extruder

Abstract

The invention discloses an ingot supply system of a short-travel front loading extruder. The system comprises a fixed arm ingot supply clamp, a movable arm ingot supply clamp, a main controller, a blank ingot position detecting device positioned in a port of the movable arm ingot supply clamp, an ingot pushing device for pushing blank ingots behind the blank ingots, an ingot pushing head positiondetecting device for detecting the position of an ingot pushing head, and a blank ingot limiting device arranged on the front side of the fixed arm ingot supply clamp. The main controller obtains ingot length data of present blank ingots according to blank ingot position data detected by the blank ingot position detecting device and ingot pushing head position data detected by the ingot pushing head position detecting device, so that ingot length types of the blank ingots are determined, and synchronous movement of the movable arm ingot supply clamp relative to the ingot pushing head is controlled according to control policies corresponding to the ingot length types. The ingot supply system of the short-travel front loading extruder can realize synchronous shrinkage of movable arms, and widens applicable blank ingot length range.

Description

technical field [0001] The invention relates to the technical field of light alloy extruders, in particular to an ingot supply system for short-stroke front-loading extruders. Background technique [0002] The short-stroke front-loading extruder refers to the extruder that feeds the material between the die and the extrusion barrel. Because the short-stroke front-loading extruder has significant structural performance and technological advantages, it is the current light alloy extrusion processing machine. The mainstream model equipped by the manufacturer. The size of the billet and the method of feeding the billet have a great influence on the production efficiency of the extruder and the stability of the equipment operation. Due to the influence of various factors such as the production cost and the dimensioning of the extruded product, the length of the billet will continue to change according to the actual production needs. Therefore, it is required that the ingot feedi...

Problems solved by technology

At the same time, the retraction action of the jaws of the movable arm of the device cannot be synchronized with the movement of the billet. It can only shrink to within the length of the billet according to the known length of the billet after the billet enters the jaws of the fixed arm and is in place. It is necessary to overcome the friction between the jaws and the ingot, and the driving power of the movable arm cannot be effectively reduced, resulting in low production efficiency
