Detailed Description

The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of this application, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit its scope.

Example 1

As shown in fig. 1-2, a specific embodiment of the utility model discloses a large-scale head hot stamping die of adjustable locate mode, including hot stamping lower mould 1, hot stamping lower mould 1's upper end be connected with two adjustable positioner that the structure is the same respectively, adjustable positioner constitute by movable part 21 and fixed part 22, movable part 21 with fixed part 22 can dismantle the connection, movable part 21 can be to the up end radial approach of hot stamping lower mould 1 to make the hot slab of different diameter sizes accurate quick with hot stamping lower mould 1 fix a position.

The utility model discloses a large-scale head hot stamping die of adjustable locate mode passes through the regulation of the movable part 21 on two adjustable positioner, can make the hot slab fix a position before 1 contacts with hot stamping lower mould, adjust the radial distance between fixed part 22 and the hot stamping lower mould 1 according to the diameter size that the hot slab is different, two fixed parts 22 are the same with the distance of horizontal plane, and the radial distance of adjusting needs also the same, thereby can pinpoint the hot slab of different diameter sizes, hot stamping efficiency is improved, increase the range of application of mould simultaneously, and the cost is saved. The utility model discloses a large-scale head hot stamping die of adjustable locate mode when the slab size changes, positioner with adjustable still can possess the ability of location to the slab, the utility model discloses a large-scale head hot stamping die of adjustable locate mode can make the accurate quick location of hot slab, not only can improve production efficiency, more enables the forging temperature and promotes, guarantees the forging quality.

During implementation, according to different diameters of the hot blank, the movable portions 21 approach different radial distances to the upper end face of the hot stamping lower die 1, wherein the radial distances of the movable portions 21 in the two adjustable positioning devices approaching the upper end face of the hot stamping lower die 1 are the same, so that the hot blank is accurately and quickly positioned. For example, when the conventional slab has a diameter D, an expanded diameter of 1.01168 × D, an outer diameter of the hot stamping lower die 1 of D1, and a radial distance of the riser 221 from the hot stamping lower die shell 11 of L, the two movable portions 21 are equally spaced radially toward the upper end surface of the hot stamping lower die 1 by L- (1.01168 × D-D1)/2.

Specifically, the fixing portion 22 comprises a horizontal plate 222 and a vertical plate 221, and the movable portion 21 is detachably connected to the vertical plate 221. In the present embodiment, the hot slab having different diameter sizes is positioned by adjusting the radial distance of the movable portion 21 from the outer shell 11 of the hot stamping lower die.

Specifically, the vertical plate 221 is provided with a screw hole, and the movable portion 21 is in threaded connection with the vertical plate 221 through the screw hole.

Specifically, the movable portion 21 is a screw, and the center of the threaded hole is located on the symmetry axis of the fixed portion 22, wherein the screw in this embodiment is a cylinder with a spiral groove cut on the outer surface, and the screw is set such that the cylinder can be a hot slab with a larger contact area with the two fixed portions 22, thereby performing accurate positioning.

It should be noted that the height from the center of the screw hole to the horizontal plane is greater than the height from the upper end face of the hot stamping lower die 1 to the horizontal plane. The purpose of this is to position the movable part 21 above the hot stamping lower die 1 to ensure that the hot slab contacts the movable part 21 prior to hot stamping and is thus accurately positioned.

Specifically, the fixing portion 22 is an integrally formed structure. One end of the transverse plate 222 is fixedly connected with the hot stamping lower die shell 11. The other end of the horizontal plate 222 is connected to the vertical plate 221, and the horizontal plate 222 is perpendicular to the vertical plate 221. The transverse plate 222 is perpendicular to the vertical plate 221 in order to fix the length of the movable portion 21, and the hot blank is then hot-stamped after being accurately positioned.

Illustratively, the cross plate 222 is welded or bolted to the hot stamping lower die housing 1. In this embodiment, the transverse plate 222 and the hot stamping lower die shell 1 are welded as an example for explanation.

In a further scheme, as shown in fig. 2, the central angle α of the position of the two adjustable positioning devices 1 on the hot stamping lower die 1 is 90-120 °. In this embodiment, 90 ° is taken as an example for explanation, because when the central angle is too small, the central angle α is the central angle formed by the symmetric central line of the vertical plate 221 in each of the adjustable positioning devices 1 at the position on the hot stamping lower die 1, and the blank cannot be well limited, and when the central angle is too large, the blank cannot be conveniently taken and placed, the utility model discloses set the central angle as 90 ° -120 °, which is not only convenient for the operator to use, but also can ensure the blank to be normally taken and placed.

The utility model discloses a large-scale head hot stamping die of adjustable locate mode simple structure, convenient operation, it is with low costs to reform transform, can effectually fix a position not unidimensional hot slab through adjustable positioner, can carry out quick accurate placing to not unidimensional hot slab, has improved hot stamping efficiency, increases the range of application of mould simultaneously, has practiced thrift the cost.
