For example, in order to prevent the steel balls from falling, the driven electrode shaft 23 is a cylindrical rod, and the driven electrode shaft 23 is coaxially fixed to the output shaft of the power element 21. The driven electrode column 23 extends toward the receiving base 15, the through grooves 2315 penetrate through the opposite ends of the movable column 231, the length of the through grooves 2315 is larger than the diameter of the steel balls, and the through grooves 2315 are used for containing the steel balls.

The end of the driven electrode column 23 is provided with a slot, the inner wall of the slot is provided with a spring, the movable column 231 is movably inserted into the slot, one end of the movable column 231, which is far away from the bearing base 15, is connected with the spring, and the power part 21 is used for driving the driven electrode column 23 to move towards the bearing base 15, so that the movable column 231 elastically abuts against the bearing base 15 and contracts, and the steel ball abuts against the end surface of the iron wire. The length of the through groove 2315 is larger than the diameter of the steel ball, so that the steel ball can be completely accommodated in the through groove 2315, the steel ball is positioned in the through groove 2315 more safely, when welding is needed, the bearing base 15 is used for pressing the movable column 231 to retract into the driven electrode column 23, the side wall of the steel ball is exposed outside and is abutted against the iron wire, smooth welding is facilitated, the movable column 231 is always arranged below the steel ball in a blocking mode, the steel ball cannot fall off, and positioning of the steel ball is stable.

For example, in order to facilitate blocking of the steel balls, the iron wire flash butt welding machine comprises a blanking assembly, the blanking assembly comprises a blanking conical shell and a blanking pipe 18, the blanking conical shell is located above the machine frame 10, and the blanking pipe 18 extends in a vertical downward direction. The upper end of the blanking pipe 18 is connected to the bottom of the blanking cone shell, the bottom end of the blanking pipe 18 is located above the through groove 2315, and the blanking pipe 18 is an elastic hose. The bottom end of the blanking pipe 18 is connected to the driven electrode column 23 through a bracket 19, and the bracket 19 is positioned at the end part of the driven electrode column 23. The roll-over stand 32 comprises a sloping plate 321 and a baffle 325 which are fixedly connected with each other, and one end of the sloping plate 321 is rotatably connected to the lower side of the end part of the driven electrode column 23. The baffle 325 is blocked at one end of the through groove 2315 and is abutted against the end surface of the movable column 231, an acute angle is formed between the baffle 325 and the inclined plate 321, and an arched flange 3258 is formed at the top of the baffle 325. The baffle 325 is completely attached to and abutted against the end surface of the movable column 231, so that the steel ball is not easy to fall off.

For example, it is particularly important that the movable column 231 is made of a ceramic material in order to improve the positioning effect of the steel ball. The blanking pipe 18 is used for conveying the steel balls into the through groove 2315, so that the steel balls are completely positioned in the through groove 2315 and a space is formed between the steel balls and the baffle 325. Compared to the situation where the side wall of the steel ball protrudes out of the end of the movable post 231, the steel ball is completely located in the through groove 2315, and cannot roll out of the outer side of the movable post 231. For example, to facilitate the turning of the turning frame 32, the height of the sloping plate 321 is gradually increased in a direction away from the receiving base 15, and the end of the sloping plate 321 is connected to the lower side of the end of the driven electrode column 23 by a torsion spring. The side of flapper 325 facing housing 10 is formed with a notch 3255 and trigger post 31 is aligned with notch 3255.

The distance between the pivot and the poke rod is smaller than the distance between the pivot and the pressing rod. The poke rod 34 is inserted into the arc-shaped guide groove 13, the pressing rod 35 is located above the frame 10, an arc-shaped half-ring 358 is fixedly arranged at the end part of the pressing rod 35, and the arc-shaped half-ring 358 is blocked and held at one side of the blanking pipe 18 facing the power piece 21. The torsion spring is mounted on the pivot and connected to the rotating rod 33, so that the rotating rod 33 drives the toggle rod 34 to move to an end of the arc-shaped guide groove 13 away from the power member 21. The rack 10 is provided with a mounting convex plate 11 in a protruding mode, the arc-shaped matching piece 36 is fixed on the mounting convex plate 11, and the arc-shaped matching piece 36 is located on one side, away from the arched half-ring 358, of the blanking pipe 18. The reset rod 38 is vertically protruded on the frame 10 and located below the end of the driven electrode column 23, the reset rod 38 is parallel to the trigger column 31, and the reset rod 38 abuts against the bottom surface of the inclined plate 321.

For example, during welding, the driven electrode column 23 moves towards the receiving base 15 under the pushing of the power member 21, the driven electrode column 23 is also used for driving the roll-over stand 32 to move towards the receiving base 15 and lengthening the blanking pipe 18, the roll-over stand 32 moves relative to the trigger column 31 so that the trigger column 31 passes through the notch 3255 of the baffle 325 until abutting against the inclined plate 321, the trigger column 31 abuts against the inclined plate 321 to force the roll-over stand 32 to turn over, so that the baffle 325 is turned over and separated from the end of the movable column 231, and finally the movable column 231 reaches the end of the receiving base 15. When the driven electrode column 23 continues to move towards the receiving base 15, the movable column 231 is further used for compressing the spring under the abutting action of the receiving base 15, the trigger column 31 is further used for forcing the inclined plate 321 to continue rotating so as to enable the toggle column to move along the arc-shaped guide slot 13, the toggle column drives the arc-shaped half-ring 358 to move towards the arc-shaped mating member 36 through the rotating rod 33, and the discharge tube 18 is clamped by the arc-shaped half-ring 358 and the arc-shaped mating member 36. At this time, the blanking cone shell is used for conveying steel balls into the blanking pipe 18 and enabling the steel balls to be clamped at the arched half-ring 358 and the arched matching piece 36. After which welding may be performed. When the welding is finished and the welding is released, the power piece 21 drives the driven electrode column 23 to retreat, the turning frame 32 releases the toggle column and restores the original shape, and the driven electrode column 23 drives the turning frame 32 to retreat so that the trigger column 31 passes through the notch 3255. Finally, the reset lever 38 is used to press against the underside of the sloping plate 321 so that the baffle 325 of the roll-over stand 32 is tightly pressed against the end of the movable post 231. At this time, the blanking tube 18 is released, the blanking tube 18 returns to the vertical direction, and the arched half-ring 358 and the steel balls at the arched fitting piece 36 fall from the blanking tube 18 into the through groove 2315.

By arranging the notch 3255 and the trigger post 31, the trigger post 31 can pass over the baffle 325 skillfully, and then the inclined plate 321 is shifted to force the roll-over stand 32 to roll over, thereby exposing the steel ball to make the welding operation go on smoothly. The trigger column 31 can further force the inclined plate 321 to rotate, so as to push the toggle column to move, the rotating rod 33 is used for driving the arched half-ring 358 to move, and the arched half-ring 358 and the arc-shaped fitting piece 36 are used for clamping the blanking pipe 18 together, so that the steel ball blanking operation can be conveniently executed in the time interval. In the process of returning to the original position, the roll-over stand 32 can return to the original position and then cross over the trigger column 31, and finally the return rod 38 tightly abuts against the roll-over stand 32, so that the roll-over stand 32 cannot be loosened due to the impact of the baiting steel balls. Through the setting of above-mentioned upset subassembly 30, greatly improved the linkage efficiency of welding efficiency and reset operation.
