Abstract
The utility model discloses a special tool for detaching a connecting pin of a cold rolling mill, which is mainly used for detaching the connecting pin of a twenty-roll Sendzimir cold rolling mill. The special tool comprises a cylindrical drum and is characterized in that one end of the cylindrical drum is provided with a groove; the inner wall of the cylindrical drum is provided with a thread; a full-length screw rod which is 230mm in length and phi 0mm in diameter is arranged on the thread; and one end of the screw rod is provided with a handle. The special tool is simple in operation, convenient to use, time-saving and safe and reliable. With the adoption of the special tool, the time for pulling out a rack connecting pin is shortened to be 4 minutes from the existing 40 minutes, and the working efficiency is improved by 20%.
Description
Technical field:
The utility model is mainly used in the dismounting of the connecting pin of Sendzimir Sendzimir mill, is specifically related to a kind of specific purpose tool of dismantling the cold-rolling mill connecting pin.
Background technology:
8 backing rolls are arranged in the Sendzimir Sendzimir mill mill housing; In the maintenance replacing process of these backing rolls, when changing wherein four B, C roller and F, G roller, need earlier the roll line tooth bar of outermost end and depress just can extract F, G roller and B after tooth bar takes out earlier, the C roller is changed.Otherwise because of the roll line tooth bar with depress tooth bar and can't four backing rolls be extracted in outermost end.
At present, owing to not having special use to pull out the roll line tooth bar and pulling out the instrument of depressing the tooth bar connecting pin, when changing; Often the operative employee can only use thin wire to hook the connecting pin central small hole to pull out outward; In the process of pulling out outward, because the iron wire head is too smooth, can't firmly hook the pin-and-hole inboard, pull-off causes iron wire to get rid of to take off and hurts sb.'s feelings and need repetitive operation just can extract connecting pin especially easily; Generally needs just can be extracted a connecting pin at least in about 20 minutes; 2 altogether, add up to about at least 40 minutes, therefore lose time especially.
Summary of the invention:
The utility model aims to provide a kind of specific purpose tool of dismantling the cold-rolling mill connecting pin of more convenient operation, high efficiency.
The utility model comprises cylindrical tube, and an end of cylindrical tube is provided with groove, and the inwall of cylindrical tube is provided with one section screw thread, and length is that 250mm, diameter are that the elongated lead screw of ∮ 20mm is arranged on the screw thread, and an end of lead screw is provided with handle.
The operation principle of the utility model is: the utility model is placed on the outside that need pull out the connecting pin tooth bar; After connecting pin aligns; Elongated lead screw is passed sleeve and is connected the pin-and-hole connection and tightens, and uses the spanner rotational sleeve, and lead screw is together extracted together with connecting pin.
The utility model is simple to operate, and is easy to use, and saves time, safe and reliable.
Use the utility model to pull out the tooth bar connecting pin time and shortened to 4 minutes, increase work efficiency 20% by existing 40 minutes.
