Added lifting receiving hopper of puncher

Abstract

The invention discloses an added lifting receiving hopper of a puncher, comprising at least three sections of lifting receiving hopper and a lifting receiving hopper base (4) which is connected with the sections of lifting receiving hopper; and the middle section (2) of the lifting receiving hopper is lifted up and down, ascends to be connected with a steel ingot (6), and descends to form a wholewith the front section (1) of the lifting receiving hopper and the rear section (3) of the lifting receiving hopper. The invention provides the added sectional lifting receiving hopper of the puncher, wherein the middle section of the lifting receiving hoper ascends to receive the steel ingot which is transported by a ingot transportation trolley, descends to form the whole with the front sectionand the rear section, so that a blank is prevented from directly hitting the receiving hopper; blank size adjusting mechanisms are arranged in the front section and the rear section of the lifting receiving hopper and are used for adjusting blanks with different diameters, so that the blanks are on a fixed rolling centerline; and the added lifting receiving hopper of the puncher has the advantages that: the structure is simple, the equipment repair is convenient, the safety factor is high, a use process is simple, and equipment is not damaged when in use and the like.

Description

technical field [0001] The invention relates to a piercing machine with additional lifting and receiving troughs. Background technique [0002] At present, the most commonly used billet for piercing machine is 9 tons, and the diameter of the continuous casting billet is Φ390~620 mm. The commonly used piercing machine receiving chute is located between two universal couplings. The elevation is lower than the rolling center line. The traditional feeding method is to send the billet to the top of the receiving trough through the ingot transport trolley, and place it directly on the receiving trough. Affected by the height, the billet will directly hit the receiving chute, which is easy to cause Equipment damage, equipment foundation damage, equipment may not be repaired and other problems; if the billet is directly rolled into the receiving chute, it will also cause equipment damage, equipment foundation damage and other problems; when the diameter of the billet is inconsistent...

[0002] At present, the most commonly used billet for piercing machine is 9 tons, and the diameter of the continuous casting billet is Φ390~620 mm. The commonly used piercing machine receiving chute is located between two universal couplings. The elevation is lower than the rolling center line. The traditional feeding method is to send the billet to the top of the receiving trough through the ingot transport trolley, and place it directly on the receiving trough. Affected by the height, the billet will directly hit the receiving chute, which is easy to cause Equipment damage, equipment foundation damage, equipment may not be repaired and other problems; if the billet is directly rolled into the receiving chute, it will also cause equipment damage, equipment foundation damage and other problems; when the diameter of the billet is inconsistent, it does not meet the feeding size of the receiving chute The blanks will be unusable, with the disadvantages of selective use of blanks, low safety factor during use, complicated use process, easy to cause equipment damage, equipment foundation damage, and equipment cannot be repaired.
