Abstract
The utility model relates to a copper strap wire squeezing machine which comprises a squeezing wheel, a compacting wheel and a squeezing mold, wherein the squeezing wheel is provided with a groove on the periphery and is connected with a power output shaft; the compacting wheel arranged on the shaft is positioned at the upper part of the squeezing wheel; a mold holder is also arranged at one side of the squeezing wheel; the inner side wall of the mold holder is matched with the outer periphery of the squeezing wheel; an arc boss on the inner side wall of the mold holder corresponds to the groove of the squeezing wheel; an arc squeezing cavity and a mold cavity which is communicated with an arc squeezing cavity are arranged in the mold holder; and the squeezing mold is arranged inside the mold cavity of the mold holder. The copper strap wire squeezing machine squeezes copper bars into the mold holder at a uniform speed, and leads the flow velocity of extruded copper bars to be stable, therefore, the extruded cooper strap wire has smooth surface without burrs, the resistivity thereof is low, and balanced resistance thereof is easily guaranteed.
Description
Technical field
The utility model relates to a kind of copper strap wire pressurizing unit, belongs to continuously extruded shape technical field.
Background technology
Paper insulation heat bonding enamel-cover semihard transposed conductor is widely used in makes high voltage, high-power transformer winding coil, it is even to have the interior CURRENT DISTRIBUTION of coil, improves the cross-sectional area of conductor current density, reduces eddy current and circulation loss, reduce heating, improve cooling, improve advantages such as coil winding efficient.It has more characteristics such as good mechanical performance and heat bonding performance except the performance with common transposed conductor.
Paper insulation heat bonding enamel-cover semihard transposed conductor is selected the high-quality oxygen-free copper bar for use, produces copper strap wire by advanced person's continuously extruded device.Continuously extruded device is made of squeegee roller, compact wheel and extrusion die, the race of squeegee roller forms extruding friction chamber with a plurality of parts with curved surface that are installed on the support, extrusion die is installed in the outer end of support, when driving through the frictional force of squeegee roller and compact wheel, the copper bar by extrusion die the crimp of copper bar is formed copper strap wire again after being introduced into the friction extrusion chamber down, to change its mechanical performance, to have the characteristics that technology is simple, production efficiency is high that add.But in the extrusion process, the flowing velocity of metal can influence the qualification rate of product, and extrusion chamber is made of the race of a plurality of part assemblings with squeegee roller, owing to made influence with factor such as assembly accumulation tolerance, because of the extrusion chamber surface irregularity, make the copper bar speed that enters in the extrusion chamber change, it is crooked easily to cause the copper strap wire of extruding to occur, and the part on the mould is easy to wear because of unbalance stress.
Summary of the invention
The purpose of this utility model provides a kind of copper bar average rate to enter the interior copper strap wire pressurizing unit of die holder.
The utility model is that the technical scheme that achieves the above object is: a kind of copper strap wire pressurizing unit, comprise squeegee roller, compact wheel and extrusion die, the squeegee roller that periphery has groove is connected with power output shaft, be installed in the top that compact wheel on the axle is positioned at squeegee roller, it is characterized in that: a described side at squeegee roller also has die holder, die holder madial wall and squeegee roller excircle match, and the arc boss on the die holder madial wall is corresponding with the groove of squeegee roller, the die cavity that has the arc extrusion chamber in the die holder and communicate with the arc extrusion chamber, extrusion die are installed in the die cavity of die holder.
Copper strap wire pressurizing unit of the present utility model is provided with die holder in a side of squeegee roller, and the excircle of the madial wall of die holder and squeegee roller matches, arc boss on the die holder madial wall is corresponding with the groove of squeegee roller, can reduce rocking of squeegee roller, improves the functional reliability of squeegee roller.The utility model is provided with arc extrusion chamber and die cavity in die holder; because the as a whole structure of arc extrusion chamber in the die holder; therefore the arc extrusion chamber is a smooth arc; the copper bar is introduced into the arc extrusion chamber under the frictional force of squeegee roller and compact wheel drives after; the copper material is fused into fluid and enters the extrusion die internal shaping under the extruding action of high temperature; because the copper bar speed that enters in the arc extrusion chamber can not change; flowing velocity when metal is extruded can be protected steadily; copper bar any surface finish after extruding does not have burr, resistivity is low, and resistance balance is easy to guarantee.
