All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 6, the present invention provides a technical solution: a stamping forming mechanism for metal structure, including mount table 1 and piercing press 3, wherein, piercing press 3 is located the top of mount table 1, a plurality of marking mechanism are installed at the top of mount table 1, marking mechanism includes fixed mounting liquid storage cylinder 12 in mount table 1 bottom, liquid storage cylinder 12's inner wall sliding connection has plectane 13, marking liquid is deposited to liquid storage cylinder 12's inner bottom, the top of plectane 13 runs through there is fixed installation cover 5, installation cover 5 still runs through mount table 1's top and with department sliding connection, the inner wall fixedly connected with marking tube 6 of installation cover 5, marking tube 6 has the capillary function, the both ends of marking tube 6 all wear out the both ends of installation cover 5, under the initial condition, the bottom of marking tube 6 does not contact with marking liquid, fixedly connected with first spring 14 between the top of plectane 13 and the bottom of mount table 1, can stretch first spring 14 when the installation cover 5 drives plectane 13 and move down, can extrude installation cover 5 and marking tube 6 and slide downwards when the top of mount table 1 with the work piece fixed laminating, the bottom of marking tube 6 can dip marking liquid.

When punching a plurality of plate-shaped workpieces, the plate-shaped workpieces are generally required to be fixed, but when multi-station punching is carried out, for example, when punching circular holes of an array, the workpiece is extremely easy to deviate and deflect due to different punching positions, the deviation is directed to displacement in a certain direction, the deflection is a certain rotation, the two accidents can cause the quality of punching to be poor, the precision is reduced, for example, the original position of array punching is influenced, deviation is formed, the mounting cannot be carried out, the inclination of punching is caused, the quality of punching per se is influenced, burrs are increased, burrs or curled edges are generated, and the like.

Therefore, we need to mark the offset and deflected plates.

When the workpiece is pressed at the tops of the marking pipes 6, the workpiece is attached to the top of the mounting table 1 through the fixed mechanism, the workpiece is kept in a certain limiting state when punching is facilitated, the bottom of the workpiece can be supported, the workpiece can be pressed against the marking pipes 6 to move downwards to a specific position in the fixing process, the marking pipes 6 can be immersed in marking liquid, and therefore the marking liquid at the bottom can rise from the bottom of the marking pipes 6 to the top in the capillary action of the marking pipes 6, and the marking liquid can be marked at the bottom of the workpiece.

In the stamping process, the workpiece may shift, when the workpiece shifts, the marking pipes 6 mark the bottom of the workpiece, the shifting direction and distance of the workpiece can be judged through the direction and distance of marking, and whether the workpiece is in a normal range or not is judged through comparison with a normal standard value, so that the recording and screening of workers are facilitated.

Even the displacement route of the workpiece can be judged through the direction and the distance, and whether the workpiece has uneven stress or not is found out.

Wherein an explanation of the labeled tube 6 having a capillary function is given: the phenomenon that the wetting liquid rises in the tubule and the phenomenon that the non-wetting liquid falls in the tubule are called capillary phenomenon.

When the marking pipe 6 is reset, the marking pipe 6 is separated from the marking liquid, and the marking liquid in the marking pipe 6 is lowered, so that the marking in a false contact mode caused by mounting a workpiece can be prevented from influencing the subsequent judgment.
