Description

The efficient stitch welding machine of high pressure wick two point

Technical field

The utility model is a kind of electric welding machine, particularly a kind of efficient stitch welding machine of high pressure wick two point that molybdenum sheet or tantalum piece are welded.

Background technology

In the prior art, when molybdenum sheet or tantalum piece are welded, all adopt single-point welding procedure pointwise welding, not only efficient is low for this single-point welding procedure, and can not guarantee welding quality.

Summary of the invention

Thereby the purpose of this utility model is to invent a kind of efficient stitch welding machine of high pressure wick two point that two solder joint stations can double efficient at least that has in order to overcome single-point welding low, the ropy shortcoming of process efficiency.

The purpose of this utility model realizes as follows: the efficient stitch welding machine of described high pressure wick two point comprises that bracing frame, last plumb joint, workpiece clamp, bottom electrode lifter and filament curve device; Last plumb joint is fixedly arranged on the top of bracing frame, and workpiece clamp is fixedly arranged on above the bracing frame, and the bottom electrode lifter is fixedly arranged on the bottom of bracing frame; Be provided with welding rod lifting electrode below the last plumb joint, be provided with welding rod below the last welding rod lifting electrode; Workpiece clamp is provided with workpiece; Be provided with bottom electrode above the bottom electrode lifter, be provided with down welding rod above the bottom electrode; Filament curves device and comprises curved silk headstock, curved silk head and curved silk cylinder, curved silk headstock is installed in the outside of bottom electrode lifter, curved silk head is two filament seats of symmetry, the filament seat is provided with the high pressure filament, the side that two filament seats are relative is a gear, gear is shipped and resell on another market by the curved silk head of vertical direction and is located at the front of curved silk headstock, the central authorities of curved silk headstock are provided with tooth bar, the exposed portions serve of this tooth bar is sandwiched between two gears, when tooth bar moves forward and backward, driven gear is done the rotation of horizontal direction, the filament seat also rotates synchronously, make high pressure filament two ends on the filament seat curve 90 ° and constitute U-shaped forward, curved silk cylinder is located at the back of curved silk headstock and is connected with tooth bar, and curved silk cylinder drives tooth bar and moves forward and backward.

Good effect of the present utility model is as follows: owing to the utlity model has two solder joint stations, so can double efficient at least; In addition, the utility model welding quality height, the saving of labor, laborsaving, can significantly reduce production cost.
