Description

Technical Field

[0001] The utility model belongs to the technical field of application of multi-directional die forging press accessories, and specifically relates to a special tooling die for a 24,000-ton multi-directional die forging press. Background Art

[0002] A multi-directional die forging press is a press with multiple slides in both vertical and horizontal directions. Using split dies, a single stroke of the multi-directional die forging press can produce forgings with complex shapes, including burrs, little or no draft, multiple branches, or internal cavities. This is a comprehensive process that combines extrusion and die forging.

[0003] Compared with ordinary die forging, it can reduce the number of processes and save energy, improve the performance of forgings, and has many unique advantages in achieving forging refinement, improving product quality and increasing labor productivity.

[0004] The multi-directional forging press can use punches in different directions and in different sequences to squeeze the blank in a closed die, so that it can perfectly fill the die cavity. After forging is completed, the die is separated, making it easy to remove the forged part from the die cavity.

[0005] Multi-directional die forging can be divided into three types based on the parting method of the forging: vertical parting, horizontal parting, and compound parting (combined vertical and horizontal parting). The current vertical parting structure design is suitable for multi-directional die forging presses (small tonnage), but how to design tooling and die suitable for large-tonnage multi-directional die forging presses requires research and solution.

[0006] Therefore, based on the above problems, the utility model provides a special tooling die for a 24,000-ton multi-directional forging press. Utility Model Content

[0007] Purpose of the utility model: The purpose of this utility model is to address the deficiencies in the prior art and provide a special tooling die for a 24,000-ton multi-directional die forging press, which adopts a vertical parting structure design and is suitable for use on large-tonnage multi-directional die forging presses.

[0008] Technical solution: The utility model provides a special tooling die for a 24,000-ton multi-directional forging press, including a skid-mounted seat, a group of dies, a forging blank and a forming pressure head. The end surfaces of both ends of the skid-mounted seat are symmetrically provided with hydraulic cylinder seats, and the hydraulic cylinder seats are respectively provided with horizontal hydraulic cylinders. The end surfaces of one end of the horizontal hydraulic cylinders are respectively provided with connecting blocks, and one side of the group of dies is respectively provided with transition connecting blocks connected to the connecting blocks. The symmetrical center surface of the skid-mounted seat and the hydraulic cylinder seats are provided with pressure-bearing platforms, and slide grooves are symmetrically provided on one side of the pressure-bearing platforms. The bottom surfaces of the group of dies are respectively provided with sliders that are stuck in the slide grooves.

[0009] In the technical solution, the special tooling die for the 24,000-ton multi-directional forging press also includes horizontal internal threaded holes arranged in the outer walls of the end faces of the pressure-bearing platform and used in conjunction with the strip slides, and threaded plugs used in conjunction with the horizontal internal threaded holes respectively.

[0010] In the present technical solution, the special tooling die for the 24,000-ton multi-directional forging press also includes a group of limiting protrusions respectively arranged on the outer wall of the die, and limiting protrusion through holes respectively arranged in the limiting protrusions, and circular limiting grooves symmetrically arranged on both sides of the pressure platform, and limiting pins that fix the limiting protrusions and the pressure platform through the limiting protrusion through holes and the circular limiting grooves.

[0011] In the technical solution of this invention, the pressure-bearing platform and the slide groove are respectively configured as rectangular structures.

[0012] In the technical solution of the present invention, the transition connection blocks are respectively welded at the symmetrical center line positions of the outer wall of the mold, and the connection blocks and the transition connection blocks are respectively welded and fixed.

[0013] Compared with the prior art, the beneficial effects of the special tooling die for a 24,000-ton multi-directional die forging press of the utility model are: 1. A group of dies move relative to each other to cover the forging blank, which can quickly and accurately cover the forging blank. The forming pressure head completes the high-quality forging forming of the forging blank, and it is also convenient to remove the formed forging, thereby realizing efficient processing of the forging; 2. The added limiting protrusions, limiting protrusion through holes and limiting pins can be used to relatively fix the covered forging blank to be extruded with a group of dies to prevent a certain displacement of a group of dies when the forging blank is extruded, thereby affecting the extrusion forming quality of the forging blank; 3. The overall structural design is reasonable, easy to make and produce, and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
