Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an extrusion head of a hot extrusion forming die comprises a mounting seat 1 and a punch 2, wherein the mounting seat 1 is connected with a hydraulic device, and the movement of the hydraulic device synchronously drives the whole mounting seat 1 to move.

And an annular groove 3 is formed in the mounting seat 1, a notch 4 is symmetrically formed in one side of the annular groove 3, the notch 4 and the groove 3 are communicated with each other, a boss 5 is symmetrically fixed on one side of the punch 2 close to the mounting seat 1, the size of the boss 5 is matched with the size of the groove 3, and the boss 5 on the punch 2 can penetrate through the notch 4 to enable the boss 5 to be mounted in the groove 3 in the mounting seat 1.

Through the technical scheme, when installing the punch 2, the bulge 5 is aligned with the notch 4, then the punch 2 is communicated with the bulge 5 and is installed in the groove 3 through the notch 4, and then the integral punch 2 is rotated, so that the bulge 5 on the punch 2 is rotated to a position away from the notch 4, the installation of the punch 2 and the installation seat 1 is realized, and then when the installation seat 1 moves along with hydraulic equipment, the integral punch 2 can be driven to enter the die, and the workpiece in the die is extruded and formed.

It should be noted that, the protrusions 5 and the indentations 4 in this embodiment are square, and may be round, triangular or other suitable shapes, and the ceramic block 6 is fixed at the end of the punch 2 away from the mounting seat 1, where the ceramic block 6 has good heat resistance and corrosion resistance, and the extrusion fit for the workpiece can be better suitable for high temperature environment relative to alloy steel, and the service life of the workpiece is prolonged.

In the practical use, because the sliding rail structure is arranged at the bottom of the punch head 2, the punch head 2 moving back and forth is supported, the mounting seat 1 and the punch head 2 do not rotate relatively, and the stability after connection can be guaranteed in a jogged mode, but in order to further avoid the problem that the bulge 5 is aligned with the notch 4 in the hot extrusion back-pulling process, the mounting seat 1 and the punch head 2 are separated, an elastic limiting piece 7 is arranged at each notch 4, the limiting piece 7 has certain elasticity, and the limiting piece 7 can be clung to the notch 4 under the action of self elasticity.

Through above-mentioned technical scheme, spacing piece 7 pivoted in-process down can be to the breach 4 shutoff, and then can restrict protruding 5 to run out from breach 4 to solve above-mentioned problem, only need rotate spacing piece 7 to keep away from breach 4 departments simultaneously can realize the dismantlement of protruding 5 and breach 4 when dismantling, the operation is also more convenient.

When the punch is used, the bulge 5 on the punch 2 is aligned with the notch 4 of the mounting seat 1, the bulge 2 is mounted in the mounting seat 1 together with the integral punch 2 after alignment, the notch 4 is also positioned in the groove 3, the integral punch 2 is rotated, the bulge 5 is embedded in the groove 3, the bulge 5 is far away from the notch 4, the punch 2 and the mounting seat 1 are mounted, and meanwhile, the punch 2 is rotated again when the punch is dismounted, so that the bulge 5 on the punch 2 is aligned with the notch 4, and then the punch is directly taken out.

Standard parts used in the application files can be purchased from the market, and can be customized according to the description of the specification and the drawing, the specific connection modes of the parts are conventional means such as mature bolts, rivets and welding in the prior art, and the machines, the parts and the equipment are of conventional types in the prior art.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
