Description
Technical Field
The utility model relates to an improvement of a graphite forming head structure of a copper bar.
Background
In the copper bar manufacturing process, the copper rolling process is important, a copper material close to a melting point is placed in a copper furnace to be melted into molten copper, and then the molten copper flows out through a forming head at the front end to form a shaped section; the industry of forming head molds is rapidly developed, and graphite is gradually the first choice material for manufacturing the molds due to good physical and chemical properties in the market,
generally, graphite is used as a forming head material.
In the process of manufacturing copper bars, liquid copper is typically made into rough copper bars using graphite molds.
The forming angle between the outer wall of the graphite mold and the axis of the through hole is generally 1 ° to 5 °, and if the slope of the outer wall is too small, the graphite mold cannot be stabilized.
If the slope of the copper rod is too large, the upper end of the graphite mold is too thin, resulting in the copper liquid cooling too fast and too large contact between the copper rod and the inner wall of the graphite mold, the copper rod is not easily removed, and the graphite mold may even be damaged.
Therefore, on one hand, the solidification temperature of each point of the copper rod is identified, and the solidification temperature of the same cross section is kept consistent as much as possible.
For square hollow bars, copper materials are rolled by adopting a mode of forming pouring holes at the periphery of a graphite core, but the bottom surface of a copper rod of an existing round graphite tube head is solidified too fast, and the rolled copper rod is easy to bend.
Disclosure of Invention
In order to overcome the not enough of present graphite jig bar copper easy bending, the utility model provides a bar copper graphite forming head that bar copper is difficult to crooked.
The technical proposal of the utility model for solving the technical problem is that: a copper bar graphite forming head comprises a die base block, wherein a bar core is arranged in front of the center of the die base block, and the section of the front end of the bar core is matched with the shape of a hollow hole in a copper bar;
the outer side of the die base block is further provided with an outer profile sleeve, the rear end of the outer profile sleeve is fixedly connected with the die base block in a sealing mode, the side face of the outer profile sleeve is provided with a plurality of pouring ports, the inner edge face of the outer profile sleeve is consistent with the outer edge face of the copper bar, and the outer edge face of the outer profile sleeve is square.
Furthermore, the number of the pouring ports of the outer profile sleeve is 4, and each of the four secondary surfaces is provided with one.
Furthermore, a locking ring is sleeved at the sealing connection position of the rear end of the outer profile sleeve and the mold base block, and a plurality of fixing bolts are arranged on the locking ring to press the rear end of the outer profile sleeve and the mold base block together.
Furthermore, the included angle between the inner wall of the outer profile sleeve and the central axis is 2-5 degrees, and the included angle between the outer wall of the rod core and the central axis is 2-5 degrees.
The utility model discloses say graphite forming head and install in the water-cooling cover when using, the pouring head intercommunication forms square copper pipe (also be applicable to the copper pipe in toast shape cross-section) between water entering rod core and the appearance sleeve pipe under the effect of gravity or pressure on the liquid outlet of copper stove.
The beneficial effects of the utility model reside in that: the square graphite forming head is matched with the square copper bar, the curing rate of each position is consistent, the integral forming performance of graphite is excellent, and cracking and bending are not easy to occur.
