Technical Field
The utility model relates to a special flash welding machine of anchor chain link welded especially relates to a device that is used for preventing that flash welding machine's moving part from twistinging, belongs to special type welding machine technical field.
Background
The anchor chain is formed by connecting a plurality of anchor chain rings with each other to form a marine anchor chain link with a standard length of 27.5m or a mooring anchor chain with a length of 1500m or more. The forming and manufacturing of the anchor chain ring comprises the following five processes: the five processes of heating the bar, horizontally bending and forming, flashing welding, removing welding burrs and pressing in the crosspiece are sequentially completed in a heating machine, a ring bending machine, a flashing welding machine, a welding burr removing machine and a gear pressing machine of the anchor chain manufacturing unit, wherein the flashing welding machine of the anchor chain ring is the most key equipment related to the quality of the anchor chain ring. As shown in FIG. 1, an operator faces an anchor chain ring blank 100 horizontally placed on a left lower electrode 10C and a right lower electrode 10D of a flash welding machine, the left side of the operator is a left electrode clamp support 20 vertically fixed on a machine body 10, the right side of the operator is a right electrode clamp support 30 fixedly connected with the left end of a welding upsetting movable table 40, the lower sides of the welding upsetting movable table 40 and the right lower electrode clamp 302 are supported on the upper side of the machine body 10 through a plurality of rows of rollers 401 arranged at intervals, an upsetting oil cylinder 402 is horizontally fixed in the middle of the upper side of the machine body 10, and the end of a piston rod 403 of the upsetting oil cylinder is fixedly connected with the inner side of the left end of. The left electrode clamp supporting seat 20 and the right electrode clamp supporting seat 30 are respectively and vertically provided with a corresponding left clamping oil cylinder 50 and a corresponding right clamping oil cylinder 60, the left clamping oil cylinder 50 and the right clamping oil cylinder 60 respectively move up and down under the guidance of a corresponding guide sleeve 501, and the anchor chain ring blank 100 is clamped or loosened by the up-and-down movement of a right upper electrode clamp 201 and a left upper clamp 301, one ends of which are respectively fixedly connected with the cylinder barrel of the corresponding clamping oil cylinder.
Before flash welding, the right upper electrode clamp 201 drives the right upper electrode 10A fixed below the right upper electrode clamp, the left upper electrode clamp 301 drives the left upper electrode 10B fixed below the left upper electrode clamp to move downwards, and the left upper electrode clamp, the left lower electrode 10C fixed on the machine body 10 and the right lower electrode 10D fixed on the right lower electrode clamp 302 vertically clamp two pairs of welding ends on one side of the anchor chain ring blank 100. During flash welding, the electrodes are energized to preheat the butt welded ends of the anchor link blank 100. Under the control of a servo valve of the flash welding machine, a piston rod 403 of an upsetting oil cylinder pushes the welding upsetting movable table 40 and the right electrode clamp supporting seat 30 to move leftwards, and at the moment, the right upper electrode 10A and the right lower electrode 10D and the right butt welding end of the clamped anchor chain ring blank 100 also move horizontally towards the left electrode clamp supporting seat 20; and then moving reversely, frequently approaching and pulling apart the butt welding ends of the clamped anchor chain ring blank, and melting metal at the contact points by resistance heat generated by the contact points of the two butt welding ends by welding current to generate strong splashing and form flash. Finally, the upsetting oil cylinder 402 pushes the right butt welding port clamped by the upper right clamp 201 and the lower right electrode clamp 302 to move towards the left butt welding port of the anchor chain ring blank 100 clamped by the upper left electrode 10B and the lower left electrode 10D at an extremely high speed, so that the left butt welding port and the right butt welding port are rapidly extruded into a whole, and the flash welding of the anchor chain ring body is completed.
