We have designed and developed many welding fixtures, especially for Automobile industries mainly for sheet metal components, which are vulnerable to thermal distortions during welding.

We have designed and manufactured many Welding Automations

ROTO-LINEAR WELDING SPM

• Hydraulic cylinder for job clamping & de-clamping.
• AC servo driven rotary table for providing required angle in linear welding on both sides of the component & semi-circle rotary movement in the end.
• Hydraulically operated linear movement for the torch on LH & RH sides of the component.
• Forward movement & home position retraction of the welding torch through hydraulic movement.
• Touch screen enable HMI (human machine interface) for the servo motor to facilitate quick changes in the angle setting & program edit.
• PLC for an efficient auto-cycle.
• LM guideways or hardened guideway strips for all linear sliding surfaces.
• Machine guard & copper sheet protection from welding spatters.

Job Description:

As shown in the above inset image, the component is unassembled halves which when assembled, resembles “Ice-candy shape”. In engineering terms the component starts off as a trapezoidal prism which ends with a curve instead of a flat.

Construction:

A rigid fabricated base on which a rotary table, driven by a servo motor is mounted. On the rotary table a job clamping fixture is mounted. Adjacent to the rotary table, a compound slide with hydraulically actuated motion is mounted. The cross axis movement of the compound slide, moves the welding torch to the pre-set required position. The longitudinal axis of the compound slide is for providing linear movement to the welding torch. A hydraulically operated clamping cylinder clamps & de-clamps the job automatically & quickly.

Working:

Place the bottom half of the job on the fixture & place the top half on it. Press auto-cycle button; Vertical hydraulic cylinder clamps the job. Welding torch approaches the welding zone of the job in its cross verse traverse. As the welding commences at the one end, linear movement slide carries the welding torch as it welds the top & bottom half till the point of beginning of the arc. Now the linear movement of the torch stops & the servo enable rotary table keeps feeding the job for semi circle welding. On sensing the end of the arc, PLC again stops the rotary movement of the table & the linear welding on the other side of the job takes place. On completing the welding, the fully welded two halves of the job get de-clamped and the machine is ready for the next job. The servo drive of the rotary table facilitates variable angle setting in linear welding and also in semi-circle welding. Total time required from clamping till de-clamping is about 30 segundos.

MULTI PORT CIRCULAR WELDING SPM

A typical automobile fuel tank has a number of ports for inlet, outlet, fuel level indication, drain etc. We have developed an automatic multi-port welding SPM, which welds the ports to the fuel tank in a single setting. A well design fixture ensures accurate positioning, clamping rigidity and buckling-resistance effects, forced by the welding heat and clamping pressure. Multiple linear slide movements, assisted by an efficient PLC programming, provide accurate location to the welding torch to commence welding of each port to the tank in rapid succession. Rotary movement, in-built in the main fixture, provides smooth & accurate circular movement to the component at the exact locations. This is an ideal, low cost solution for medium volume component industries, engaged in the manufacture of sheet metal components, like fuel tanks, silencer etc.

LEAK TESTING MACHINES

This leak testing machine is developed on a rotating giant wheel principle, which accommodates multiple components to be leak tested to the machine. It also helps to minimize the mess generated by the conventional leak testing machines by splashing of leak testing liquid. On rotating wheel, 4 fuel tanks are mounted. As one fuel tank gets immersed in the liquid for identifying the leaking welding joint, previously tested tank is to be removed from the wheel and a new tank is to be mounted. Like this, there is a provision for mounting 4 tanks in the wheel. The tank, wheel and other vital parts of the machine are made of stainless steel.

CNC WELDING SPECIAL PURPOSE MACHINE

Ofrecemos ampla gama de solucións de soldeo como soldeo rotadores, Posición de soldeo, Columna & Manipuladores de Barra, Sistemas de automatización de soldeo, manipuladores de soldeo etc. A Welding SPM consiste nun dispositivo eléctrico de soldeo para localizar con precisión os compoñentes e sostendo firmemente & os compoñentes de presione na posición requirida. As dimensións de localización son centrais nunha máquina de furar GABARITO e elementos de fixación consiste en U ou V bloques, manter-down elementos, patas de localización, arbustos etc. O equipo está deseñado para localización precisa dos compoñentes repetidos e consistente. O grapa de correo Clamp mecanismo automático é xeralmente por medio de cilindros de accionamento pneumático. En función das necesidades de soldadura dos compoñentes que son para ser soldadas, accesorio pode manter os compoñentes en posición fixa ou un mecanismo de quenda pode ser proporcionada. Guías lineais, cargando as facho, é a esencia da SPM soldeo.

Neste soldadura SPM CNC, ten 6 facho, simultaneamente soldeo ambas finais flanges para un tubo cadrado en 20 segundos. A rápida aproximación dos soplete para a zona de soldadura, soldeo real e retracción rápida das facho través de diapositivas adecuadamente deseñados son a través de servo-motores e accionamentos. Unidade Servo garante movemento preciso e axuda a manobrar repetidamente os tipos de alimentación de acordo coa esixencia. As guías lineais consisten en guías lineais, parafusos de chumbo balón e porcas da caixa para un suave & movemento libre de atrito.

Sistema eléctrico está composto por servomotores e drives para os movementos lineais dos fachos, que obedecen aos mandos a partir da combinación de PLC & interruptores de límite. O sistema eléctrico é ben deseñado para un ciclo de auto eficiente de todos os movementos lineais e tamén de ejeção emprego a través cilindros de ejeção tras soldeo e retracción dos diapositivas para os cargos na casa. Para coidar de distintas lonxitudes de traballo, VFD controlado mecanismo de axuste de lonxitude subministrado. A IHM agradable axuda o operador a edición de programa en Usinagem facilmente e nun tempo moi curto.

Excepto a carga e descarga dos traballos, secuencia de soldeo completo, incluíndo ejeção traballo tras a soldeo é totalmente automático. Máquinas automáticas de soldeo producir boa e uniforme calidade de soldeo de forma consistente sen ser realizada por calquera dos factores negativos da soldeo manual como fatiga, erro humano, etc. Resolución de soldeo automática pode impulsar a produtividade, tanto como 20 veces.
