Description

The medium frequency inverter grating plate press welder

Technical field:

The utility model relates to a kind of solder technology, and particularly a kind of medium frequency inverter welding manner will be arranged the load band steel that is positioned between positive and negative electrode by certain way, and pressure welding becomes the press welder of flase floor with cross bar.

Background technology:

Flase floor is a structural material commonly used in the modern industry, be mainly used in industries such as infrastructure project, municipal works, petrochemical industry, power equipment, at present, the press welder that domestic existing flase floor manufacturer adopts, power supply has and exchanges and two kinds of power frequency (50Hz) direct currents, these press welders exist that efficient is low, fault rate is high, matching transformer power greatly, defective such as poor welding quality.

Summary of the invention:

The purpose of this utility model just provides a kind of efficient height, fault rate is low, matching transformer power is little, welding quality is good intermediate frequency (1000Hz) inversion grating plate press welder.

The purpose of this utility model is achieved in that a kind of medium frequency inverter grating plate press welder, form by lower bottom base, cylinder, time clamping plate, top electrode, guide pillar, master cylinder, upper bed-plate, slide block, last clamping plate, bottom electrode, last clamping plate cylinder, it is characterized in that described slide block both sides connect at least 3 pairs of intermediate-frequency transformers and rectifier assembly, be connected in series between each intermediate-frequency transformer and the rectifier assembly, each intermediate-frequency transformer is connected in parallel.

An optimum implementation of the present utility model is: intermediate-frequency transformer output voltage 12V, the training of electric current 30 Wan An, frequency 1000Hz; The leading flank of lower bottom base connects servomotor, the output of servomotor connects ball-screw, the ball-screw upper end connects the clamping plate base, the middle part of clamping plate base upper end is connected with described cylinder, two ends connect the clamping plate guide pillar, clamping plate guide pillar upper end is connected with described time clamping plate, is connected vertical guide pillar between lower bottom base and the clamping plate base.

The utility model compared with prior art has the following advantages:

Owing to adopt the slide block both sides to connect at least 3 pairs of intermediate-frequency transformers and rectifier assembly, be connected in series the version that each intermediate-frequency transformer is connected in parallel between each intermediate-frequency transformer and the rectifier assembly, thereby, simple in structure, easy to use, consumptive material is few, saves the energy and space, and welding efficiency improves.
