Description
Technical Field
The invention relates to the technical field of extruders, in particular to an extruder ingot supply device and an extruder ingot supply method.
Background
Extruders are the primary means of producing light alloy (e.g., aluminum, copper, and magnesium alloy) tubes, rods, and profiles. The billet size and the ingot supply mode of the extruder have great influence on the production efficiency of the extruder and the running stability of equipment, and because the length of the billet can be continuously changed according to the actual production requirement due to the influence of various factors such as the production cost, the scaling of an extruded product and the like, the ingot supply device of the extruder is required to be applicable to a larger billet size range.
Chinese patent publication No. CN108393366A entitled "ingot supply system of short-stroke front-loading extruder" discloses an ingot supply device and an ingot supply method implemented by using the same. The ingot supplying device utilizes a fixed arm ingot supplying clamp and a movable arm ingot supplying clamp to jointly support billets, and the movable arm ingot supplying clamp can automatically adjust and move according to the ingot length data of the same batch input into a movable clamp control program in advance or the ingot length data detected by a related auxiliary mechanism and the nesting speed of an extrusion container. When the ingot feeding device works, a billet is pushed onto a movable arm of the ingot feeding device by the ingot pushing device through the ingot conveying trolley, the movable arm of the ingot feeding device automatically stretches to a proper position according to the length of the billet and then sends the billet into the center of an extruding machine, the billet is clamped with a mold through an extruding rod, a jaw of the movable arm and a jaw of a fixed arm of the ingot feeding device are opened at the moment, the movable arm gradually shrinks to the position with the shortest length of the billet along with the nesting speed of an extruding cylinder, and then the sliding frame moves to drive the movable arm and the fixed arm to withdraw from the extruding center, so that one-time ingot feeding action cycle.
In the existing ingot supply method, the contraction action of the movable arm mainly has two functions, firstly, the contraction action is adapted to different ingot lengths to meet the requirement of ingot supply space, secondly, after a billet is clamped by an extruder, the billet advances along with the extruder based on the nesting speed of the extruder, the extruder is prevented from beginning nesting after the movable arm and the fixed arm exit from an extrusion center, and the non-extrusion time is reduced.
Although the above two functions can be achieved when forward extrusion is performed using the existing ingot feeding apparatus. However, when backward extrusion is performed, because the fixed arm is arranged on the side of the ingot supply device which needs to follow after entering the center of the extruder, the non-extrusion time cannot be shortened because the movable arm follows the extrusion container during forward extrusion, and the extruder needs to wait for the movable arm and the fixed arm to withdraw from the extrusion center before trepanning, so that the production efficiency of the extruder is reduced.
Therefore, how to ensure that the ingot supplying device can meet the requirement of the ingot supplying space by adapting to different ingot lengths when forward extrusion and backward extrusion are carried out, and can also follow the extrusion container to advance so as to shorten the non-extrusion time, improve the production efficiency, and become a technical problem to be solved urgently by technical personnel in the field.
