Abstract

A B S T R A C T

The machine for three dimension shaping and/or straightening of steel plates with flame and/or laser heating followed by water or air cooling, has the task of substituting the con-ventional shaping equipment such as rolls, presses, flangers, etc, which require considerable investment. It is very portable and can operate independent of any specialized place as workshop, yard, etc. Consisting of a carriage moving on magnetic chain track and/or magnetic wheels carrying and operating remote controlled and/or programmed torches and/or lasers and cooling nozzles, applying heating followed by cooling on the surface of steel plates performing in this manner the required shaping. To assure during the process the working temperature does not exceed allowable range, the temperature control device adjusts at all times the movement speed of the carriage. Thus it is possible to obtain the shaping of the plate saving valuable time and investment.

S P Hi C I F I C A T I O

This invention relates to a machine for three dimension shaping

2. and/or straightening of steel plates as defined in Claim 1. It is common equipment for cool shaping of the steel plate such as rolls, presses flankers, etc. Etch of these types of equipment can perform the plate shaping only in one dimension at a time. To shape three dimension plate it is necessary to use as en mule, the roll for rolling and after the rest pective transversal curvature is obtained the longitudinal curvature can be performed with powerful press. This equip-mint is expensive and very heavy, requiring maintenance end an adequate workshop for its operation and-especially

3. operators with high qualifications.

~L2382G2 I have found these disadvantages may be overcome by providing a machine for shaping the steel plates using the effect of bonding produced by the thermal stresses end strains appearing as it result of hefting end immediate cooling with water or air on a portion of the respective plate. This procedure being performed below the temperature which con make any modification into internal structure of the material to be shaped. This machine easily curried by one person, inexpensive, does not require maintenance and substitutes with success all the other

4, conventional shaping equipment.

"In drawing which illustrates embodiment of invention, Figure 1 is an elevation of the embodiment of invention.
Figure 2 is top view of this embodiment.
Figure 3 is a profile partial in section of the embodiment.
The machine illustrated comprises the carriage (1) with two brackets (21) which is constructed to ensure remote controlled and/or programmed movement and operation of the hefting torches and/or laser (3) in conjunction with cooling nozzle (43. The carriage is running on the magnetic chain track (2) nor mug-

5, netic wheels t20) in any working position. The mechanism for performing triangular pattern of hunting ~12) allows for a con-trolled lateral movement of the shaft (11) on which thy hefting torches and/or lasers end the respective cooling system are erected. Inside of the carriage are fitted the drive system (7 the oxygen distributor (9) the burning gas distributor I the water distributor (10) the igniter (13) oxygen solenoid valve ~17) gas solenoid valve I water solenoid valve (19~ flush back gas tl6) oxygen flush back (21) end hoses (22) belonging to the hefting and respective cooling system (23~, ~238~

6. The safety device (5) controls at all times the temperature of the steel plate at the point of hefting. If the temper-azure exceeds the allowable range which can produce a strut-rural modification of plate the oxygen solenoid valve (18) closes and/or laser's electric supply switches off. The same device controls and adjusts the speed of carriage.

SUPPLEMENTARY DISCLOSURE

The transmitter of level (25~ erected on the carriage trays-mitt co-ordinates (u, v, w,) information bout the curved plate and the respective twist, to the programmed controller (24). If the depth of the considered point is equal with the requirement, the controller (24) I final element ~26) closes the respective torch and/or loser.

Claims

C L A I M S

1. Machine for three dimensions shaping of steel plates using the method of heating with flame followed by cooling with water having application especially in shipbuilding and steel building characterized by the machine consisting of a carriage on magnetic chain track traveling in all working directions on the respective plate with a programmed equipment capable of carrying and operating more torches as source of heating and the conjugate nozzle as source of coolig, a carriage speed control device which controls its speed in accordance with prescribed temperature at point of heating.

2. A machine according to the Claim 1,characterized in that a transmitter for level reading and delivering informations about the three dimensions shaping of plate during the process, toward a programmed controller which in conformity with the input data from a computer reading the final required shape of plate, regulates the bending process, switches on/off the torches at the proper time.

3. A machine according to Claims 1,2, characterized in that beside torches is capable to use laser as heating source.
