Description

A mould for producing big width-thickness ratio copper bar

Technical Field

The utility model relates to a mould for producing big width-thickness ratio copper bar belongs to extruder mould technical field.

Background

The copper bar is a high-current conductive product, is suitable for electrical engineering of high and low voltage electrical appliances, switch contacts, power distribution equipment, bus ducts and the like, and is also widely used for super-high current electrolytic smelting engineering of metal smelting, electrochemical plating, chemical caustic soda and the like.

At present, due to the limitation of a continuous extrusion principle, equipment capacity and the design of the existing die, a continuous extruder for producing a copper profile product with large size and large width-thickness ratio needs high equipment capacity, but the continuous extruder is expensive and has overhigh cost for research and development; meanwhile, in the production process of the copper bar with large size and large width-thickness ratio, the defects of insufficient filling, distortion, raised grains, uneven size and the like are easy to occur, the processing procedures are complicated, and a plurality of procedures are needed sometimes, so that the finished product rate of the copper bar with large size and large width-thickness ratio is poor.

Therefore, how to produce the section bar with large size and large width-thickness ratio which cannot be produced originally by using the continuous extruder with small production capacity is a problem to be solved, thereby saving the cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem of proposing among the above-mentioned background problem, provide a mould for producing big broadness and thickness ratio copper bar, it can utilize little production capacity's continuous extrusion machine, produces the section bar of jumbo size, big broadness and thickness ratio, has practiced thrift equipment cost greatly.

The purpose of the utility model is realized like this: a die for producing a copper bar with a large width-thickness ratio comprises a die body, wherein the die body is of a cylindrical structure and is divided into a feeding surface and a discharging surface;

the feeding surface is provided with a feeding hole, the feeding hole is integrally in an inverted U shape, and two end points of the feeding hole are connected in an inclined upward direction to form inverted V-shaped connection;

the discharging surface is provided with a discharging notch with an inverted U-shaped structure;

the feed inlet is connected with the discharge notch through an arc inclined plane.

The die body is also provided with a die cavity in a matching way;

the die cavity is a square structure with four chamfered corners.

The bottom surface of the die cavity is provided with a square opening, the top surface of the die cavity is provided with a door-shaped notch, and the top of the notch is arc-shaped;

the notch is connected with the square opening through an inclined plane.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses a mould for producing copper bar with large width-thickness ratio, which can utilize a continuous extruder with small production capacity to produce sectional materials with large size and large width-thickness ratio, thereby greatly saving the equipment cost; meanwhile, the requirements of product forming on the equipment capacity are reduced by controlling the die structure, the yield of the copper section is improved, the production period of the product is shortened, and the production efficiency of the product is improved.
