Embodiment Construction

[0020] A precision push-pull wire feeding device includes a double crankshaft 7, one end of the shaft is connected with a motor 8, and there are two eccentric cams A and B in the same direction on the shaft. The eccentric radius of cam A is r 1 , the eccentric radius of cam B is r 2 , r 1 ≠ r 2 , Two or more three-ball wire feeding chucks are arranged front and back, and are connected to cam A and cam B with different movable connecting rods 9 and 10 respectively; the number of movable connecting rods is not limited. When the motor rotates, the eccentric cam rotates, and each three-ball wire feeding chuck moves back and forth synchronously with the eccentricity under the support of different movable connecting rods, and the distance of the forward and backward movement is equal to twice the eccentric radius;

[0021] The three-steel ball wire feeding chuck includes a cylindrical sleeve 1, a steel ball cage 4 is arranged inside the cylindrical sleeve, a three-steel ball mech...

Abstract

The invention discloses a precise push-pull wire-feeding device. The device is characterized by comprising a double-crank shaft, wherein one end of the shaft is connected to a motor; two homodromously eccentric cams A and B are arranged on the shaft; the eccentric radius of the cam A is r1, the eccentric radius of the cam B is r2, and r1 is not equal to r2; two or more three-steel-ball wire-feeding chucks are arranged front and back and are connected to the cams A and B through different movable connecting rods, respectively; when the motor rotates, the eccentric cams rotate, and the three-steel-ball wire-feeding chucks, supported by different movable connecting rods, perform front-and-back movements synchronized with eccentric movements, respectively. The device disclosed by the invention is reasonable in structure and has a low cost and high reliability.

Description

technical field [0001] The invention relates to a push-pull wire feeding device. Background technique [0002] Gas shielded welding (referred to as gas shielded welding) has the advantages of high production efficiency, low cost, and low energy consumption, and is widely used in production practice. At the same time, gas shielded welding also has disadvantages such as unstable welding spatter and deviation of weld formation. In order to reduce the spatter rate of gas shielded welding and improve the quality of weld seam, it is necessary to make the droplet transfer of gas shielded welding regular. The most effective way to achieve this is to change the traditional constant-speed continuous wire feeding method, that is, to use push-pull wire feeding. [0003] Push-pull wire feeding means that when the wire feeding step and push-pull frequency are appropriate, the droplet transition in gas shielded welding changes from the chaos of constant-speed wire feeding to "one drop at...
