Abstract
The utility model discloses a wire drawing die for solder wires. The inner hole of a die core is arranged on the wire drawing die, and consists of an entry area, a compression area, a sizing area and a releasing area which are connected. An entry angle, a compression angle and a releasing angle are arranged on the corresponding entry area, the compression area and the releasing area; a sizing diameter and a sizing length are arranged on the corresponding sizing area; the scope of the compression angle is of 10-16 degrees; the ratio scope of the sizing length and the sizing diameter is of 30-45 percent; the solder wires produced by using the die to draw wires has high surface cleanness and uniform plastic deformation, thereby being capable of improving the wire feeding performance and linear stability of the solder wires, and straightening a welding bead. The size of the entry angle is equal to the size of the compression angle to prevent powdered lubricant from spilling out reversely due to the stop of the compression angle in the compression area after entering the entry area and lead the powdered lubricant to enter sufficiently.
Description
Technical field
The utility model relates to a kind of wire drawing die, particularly a kind of wire drawing eye mould that is used for welding wire.
Background technology
The eye mould is that a kind of wire rod is stretched the mould that line is used, the wire rod that uses the eye mould to stretch line must have the ability of plastic deformation, the large aperture limit of wire rod by the eye mould penetrated, utilize the plasticity extension of wire rod that wire rod is pulled out from the limit, small-bore, just can dwindle the line footpath of wire rod metal wire gradually, promote the smoothness of wire surface simultaneously, finish the manufacturing of stretching line.The eye mode structure of manufacturing industry use at present is different, but substantially all has the part of compressional zone and these two most criticals of sizing area.The structure of eye mould has influenced the quality after the wire rod wire drawing to a great extent.Welding wire is as a kind of wire rod of specific use, and the cleannes and the plastic deformation rate on the surface of wire rod after the wire drawing all had higher requirement, and general eye mould is difficult to obtain satisfied effect.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of wire drawing eye mould of welding wire, and this mould can be controlled the plastic deformation rate and the remained on surface lubricating film bits amount of wire rod drawing process preferably.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of wire drawing eye mould of welding wire, described wire drawing eye mould is provided with the intracardiac hole of mould, the intracardiac hole of described mould connects to form by entering district, compressional zone, sizing area and release district, correspondence enters district, compressional zone and release district and is provided with entering angle, compression angle and separation angle, corresponding sizing area is provided with sizing diameter and sizing length, the scope of described compression angle is 10 °-16 °, and the ratio range of described sizing length and sizing diameter is 30%-45%.
As further improvement of the utility model, the angular dimension of described entering angle equals the angular dimension of compression angle, prevents that powdered lubricant is after entering the district, be compressed stopping of compression angle in the district, oppositely overflow, make powdered lubricant fully enter, the scope of described separation angle is 30 °-70 °.
The beneficial effects of the utility model are: use this mould to stretch the welding wire surface cleannes height that line is produced, plastic deformation is even, thereby can improve the wire feeding property and the Linear Stability of welding wire, make welding bead straight, the angular dimension of described entering angle equals the angular dimension of compression angle, prevents powdered lubricant after entering the district, is compressed stopping of compression angle in the district, oppositely overflow, make powdered lubricant fully to enter.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment: a kind of wire drawing eye mould of welding wire, described wire drawing eye mould is provided with the intracardiac hole of mould, the intracardiac hole of described mould connects to form by entering district 1, compressional zone 2, sizing area 3 and discharging district 4, correspondence enters district, compressional zone and release district and is provided with entering angle 5, compression angle 6 and separation angle 9, corresponding sizing area is provided with sizing diameter 7 and sizing length 8, the scope of described compression angle 6 is 10 °-16 °, and described sizing length 8 is 30%-45% with the ratio range of sizing diameter 7.
The angular dimension of described entering angle 5 equals the angular dimension of compression angle, prevents powdered lubricant after entering the district, is compressed stopping of compression angle in the district, oppositely overflows, and makes powdered lubricant fully enter, and the scope of described separation angle 9 is 30 °-70 °.
Wherein compression angle 6, sizing diameter 7 and sizing length 8 are to influence the topmost factor of welding wire quality, and entering angle 5, separation angle 9 are secondary causes.
The size of compression angle 6 can influence the plastic deformation rate of welding wire, and plastic deformation is even more, and the linearity of welding wire is stable more.
Finish line footpath after the wire drawings of sizing diameter 7 decision welding wire.
Sizing area 3 length influence the surface cleanness of welding wire.The sizing diameter value is big more, and welding wire is long more with eye mould fraction time, and the amount of residual powdered lubricant is few more.But after the sizing diameter value delimits above one, easily with the welding wire surface plucking.
The effect of entering angle 5 is to be convenient to be coated with the last layer powdered lubricant at welding wire surface, and makes lubricating film even.
The effect of separation angle 9 is heat radiations.Because high-speed friction can produce very big heat, bigger separation angle can be accelerated heat radiation to the eye mould in the process of wire drawing.
Reasonably above these parameters are adjusted the surface cleanness and the Linear Stability that just can improve wire rod.Thereby improve the serviceability of welding wire.
