Description

High-speed punch with automatic blanking and stripping functions

Technical Field

The invention belongs to the field of punching machines, and particularly relates to a high-speed punching machine with automatic blanking and stripping functions.

Background

Various valve plates can be applied to modern automobiles, and the automobile valve plates made of metal materials are usually formed by stamping through stamping equipment.

The applicant previously applied for, application number 2019210284953 discloses an application double-end mold's car valve block stamping equipment, relates to valve block production, aims at solving the problem that control is inconvenient and production efficiency is lower, and its technical scheme main points are: an automobile valve plate stamping device using a double-head die comprises a feeding mechanism, a punch press, a blanking assembly and a traction mechanism, wherein the feeding mechanism comprises a base, a turntable and clamping jaws; the punching machine comprises a rack, a crankshaft, an alternating current motor and a punching seat, wherein the rack is provided with a braking structure, a linkage structure is arranged between the crankshaft and the braking structure, a main transmission rod is arranged between the crankshaft and the punching seat, the punching seat is provided with an upper die, and the rack is provided with a lower die; the blanking assembly comprises a material receiving box, a push-down vertical rod, a guide funnel and a horizontal arm; the traction mechanism comprises a traction frame, a traction roller set and a traction motor, the traction roller set comprises an inner shaft and an outer roller, the control is more convenient, and the coordination and the production efficiency are effectively improved.

When the above patent works, the traction mechanism pulls out raw materials, the raw materials are suspended to advance through the brake structure, then the upper die acts to blank the raw materials, meanwhile, the vertical rod is pushed down to push the valve plate to separate the valve plate from the raw materials, and the limiting force provided by the brake structure is larger than the friction force of the inner shaft and the outer roller, so that the traction motor does not need to be shut down.

However, when the upper die and the lower die are closed, the upper die actually cuts a raw material knife mark on the raw material, and the valve sheet is not directly separated, that is, the upper die only needs to move a few millimeters (determined according to the thickness of the raw material) after contacting the raw material, and the push-down vertical rod on the rear way needs to move a longer distance to push away the valve sheet, that is, the push-down vertical rod needs to contact the valve sheet and apply an acting force before the upper die contacts the lower die, and usually, the upper die only contacts the lower die after the valve sheet is pushed away from the raw material, so that the raw material shakes before the upper die contacts the raw material, the blanking effect is influenced, and sometimes the raw material or part of the raw material is separated by directly vibrating the valve sheet which is just blanked in front (not reaching the push-down vertical rod).
