Description

Test bench for welding torches.

Object of the invention

The present specification refers to a request for a Utility Model corresponding to a bank of test for welding torches, whose obvious purpose lies in simulating the three circuits that configure the hose welding, consequently creating the conditions of operation required for checking.

Field of the Invention

This invention has its application within the industry dedicated to the manufacture of test benches, especially for welding torches.

Background of the invention

The applicant is unaware of the existence in the actuality of an invention that is endowed with the characteristics which are described herein.

Description of the invention

The test bench for welding torches that the invention proposes is constituted from a circuit of water, a gas circuit and an electrical circuit, on the which will first be the connection of the car of testing a standard power outlet and another air outlet to subsequently connect the hose to be repaired using the relevant connection.

More specifically, the test bench for welding torches object of the invention is configured to from three fundamental elements constituted by a circuit of water, a gas circuit and an electrical circuit.

The water circuit is formed by a pump of water integrated in the test car itself and the circuit gas, which is capable of being replaced by pressurized air, It can be connected to an air network by incorporating a quick plug.

The electrical circuit incorporates a "tester" with which the measure will be carried out properly derived from the part of the hose corresponding to the trigger and cable test of current.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is accompanied herein descriptive, as an integral part of it, a set of planes in which with an illustrative and non-limiting nature, it has been represented the following:

Figure number 1.- Represents a view in perspective of the object of the invention corresponding to a bank of test for welding torches.

Figure number 2.- Shows a detail of the electrical test circuit

Preferred Embodiment of the Invention

In view of these figures it can be seen that the test carriage is constituted from a structure that It has on the bottom wheels (13), a lower tray (15), vertical support means (14) and at the top a tray (16), having a water pump (1), as well as a gas circuit that can be replaced by pressurized air using an air network using a quick plug or connection fast (2).

The invention incorporates an electrical circuit equipped with a "tester" (4) with which the area of the hose corresponding to the trigger and cable test current, this element is located at the top of the tray (16).

To obtain its operation, the test cart to a standard power outlet and to another air and then the hose to be repaired in the connection referenced with (5).

To perform the trigger check just activate the "tester" (4) and observe the data existing on the screen, knowing if the cable trigger is broken or makes a bad connection or is derived for a possible water leak.

To check the power cord, we will touch on the connection (6) of the panel with the contact tube of the torch, and we will observe that the measurement value does not exceed 3 \Omega.

If the invention when performing this action determine another value, you can define that the power cable it's broken.

In case it is available under the checks currently made and there is suspicion or doubt that the cable is broken, the hose will be removed from the hose and will repeat the checking operation, verifying that the reading of the "tester" is higher than indicated above, being able to reach 10 K \ Omega.

The power cable can break very frequently due to the twists arising from the performance of the hose during its work, since it has a small diameter and is very fragile and, at the same time, is cooled by water, it usually breaks internally and stops working without previously determining any symptoms or external action of the breakage or deterioration performed on the
same.

To check the gas circuit the invention must be acted in order to make an assurance of a hermetic seal, replacing the fractured o-rings of the gas inlet of the hose and subsequently opening the handle and, with pliers or similar elements, it throttle the gas tube at the point referenced with (8), subsequently opening the air passage referenced with (7), verifying that the flowmeter needle (17) is set to zero and thus it is confirmed that there is no leak.

Regarding the circuit check water should indicate that this operation is performed with the handle of the open hose, acting on the switch (18) of the water pump (1) and operating the circuit, checking whether or not there is a water leak and observing that the Pressure and return connections are completely tight.

Through the open stopcock (10), observe the return that must be fluid and constant, providing such effect a circuit to be able to visualize the mentioned return, and in the case described above, the invention of a funnel (9) in which the return water is collected before it be incorporated into the pump (1).

Subsequently, the key must be closed (10) consequently reaching a maximum pressure in the circuit and again checking the tightness of it, since this This way the check will be forced as the pressure increases.

The test bench is complemented by an air blow gun (11) intended to be an element of great utility to quickly dry small traces of water that may affect the reading of subsequent checks as well as of a pressure regulator (12) to avoid overpressures excessive that may affect the torch and simulate normal working pressures of the welding torch in question.

As stated above, the structure incorporates wheels (13) for small displacements of the testing bench.
