Description

Automatic head hot stamping die of drawing of patterns

Technical Field

The utility model relates to a hot stamping head in pressure vessel field especially relates to an automatic hot stamping die of head of drawing of patterns.

Background

At present, carbon steel end sockets used for pressure containers are generally formed by hot pressing, and the demoulding mode is generally divided into an automatic demoulding mode and a rigid demoulding mode. The automatic demoulding is realized by separating the sliding sleeve from the end socket, and the rigid demoulding is realized by clamping the edge of the end socket by a ground hook or an inserting plate during demoulding to realize rigid demoulding of the end socket from the mould.

Although the rigid demoulding is simple, the forming quality of the end socket is greatly influenced, and the ovality and the circumferential dimension of the end socket after being cooled are over-poor due to the defects that the forming phenomenon and the like are easily caused by steel plates made of certain materials. In actual production, the method has many defects, high production cost and poor economy, and heavy work is brought to subsequent end socket repair.

The main difference between the mould with the end socket capable of automatically demoulding and the mould with the rigid demoulding is that a sliding sleeve capable of being pressed down along with the upper tyre is added on the upper tyre. The working principle is that after the end socket is formed, the sliding sleeve continues to move downwards along with the upper tire, when the end socket passes through the inlaying ring, the sliding sleeve is in contact with the blank holder and does not move downwards any more, the end socket is automatically separated from the upper tire, and the end socket is pressed; when the upper tire is lifted, the sliding sleeve and the upper tire return to the original state again, and the next end socket is continuously pressed.

The mould with automatic demoulding avoids the disadvantages caused by adopting a mould with rigid demoulding. However, the production process has many defects because each seal head of each specification generally only has one universal upper tire, and the shrinkage of the seal head with different plate thicknesses and materials is different; the pressure that different head bore in the mould is different, and it influences the ellipticity of head to go up child deformation, can't guarantee the ellipticity and the circumference size of head. The time of the end sockets with different thicknesses and different materials in stamping and demoulding is basically the same, and the difference of the thicknesses and the materials directly causes the difference of the cooling shrinkage after the end sockets are demoulded, so that the circumferential dimension of the end sockets with the same specification, different thicknesses and different materials after stamping is out of tolerance.

Therefore, an automatic demoulding mould is urgently needed, the mould is not limited by the thickness and the material of the end socket, the residence time of the end socket in the mould can be controlled to the maximum extent, and the upper mould is not deformed and damaged in the pressing process, so that the circumferential size of the cooled end socket is ensured, and the ovality requirement of the end socket is also ensured.
