Description

Technical Field

[0001] The present application belongs to the technical field of hydraulic presses, and more specifically, to a vertical double-worktable double-moving forging hydraulic press. Background Art

[0002] Vertical forging hydraulic press is an advanced forging equipment, which is widely used in the field of metal processing. It has brought great changes to the metal processing industry. It not only improves production efficiency and reduces production costs, but also can meet the needs of more customized production, bringing more business opportunities to enterprises.

[0003] However, the traditional vertical forging hydraulic press still has certain limitations during use. For example, in the production of half-axle forgings with flanges and shaped structures inside the flanges, the rod portion of such forgings usually does not need to be formed, while the flange portion generally requires a two-step forging process of pre-forging and forming. In the traditional process, different punch heads need to be replaced and the pre-forged forging blanks need to be taken out from the pre-section lower die and then loaded into the forming lower die for stamping and forming. This process is time-consuming and labor-intensive, which greatly reduces the forging efficiency of the hydraulic press; therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a vertical double-worktable double-moving forging hydraulic press to solve the technical problem of low forging efficiency of hydraulic presses in the prior art.

[0005] To achieve the above purpose, the technical solution adopted in this application is: to provide a vertical double-worktable double-moving forging hydraulic press, including:

[0006] A lower die seat, used for mounting the lower die;

[0007] A platform assembly, comprising a first workbench and a second workbench capable of approaching or moving away from the lower die base along a first direction, wherein the second workbench is located between the first workbench and the lower die base and has at least three through holes evenly spaced along a second direction, wherein the first direction is perpendicular to the second direction;

[0008] A forging assembly comprises a first sliding die seat slidably connected to the first workbench and a second sliding die seat slidably connected to the second workbench, the first sliding die seat and the second sliding die seat are used to slide synchronously along the second direction, the first sliding die seat is provided with pre-forging punches and forming punches spaced apart along the second direction, the second sliding die seat is provided with two through holes corresponding to the pre-forging punches and the forming punches, the lower end surface of the second sliding die seat is used for installing the pre-forging upper die and the forming upper die at the coaxial position of the two through holes, and the spacing between the through holes is equal to the distance between the pre-forging punches and the forming punches and the distance between the through holes.

[0009] Optionally, the vertical double-worktable double-mobile forging hydraulic press further includes a base and a box beam connected by a column, the lower die seat is mounted on the base, and the first worktable and the second worktable are both slidably connected to the column.

[0010] Optionally, the first workbench and the second workbench are sleeved on the column.

After the pre-forging process is completed, it is only necessary to reset the first worktable and the second worktable and make the first sliding die seat and the second sliding die seat slide synchronously along the second direction, so that the forming punch can be formed through the through hole in the middle, and the pre-forging punch can be temporarily accommodated in the through hole on the other side to avoid interference with the second worktable. As a result, there is no need to frequently replace the punch head and remove the forging blank from the lower die during the stamping process of the metal forging, which greatly improves the forging efficiency of the hydraulic press and is conducive to ensuring the quality of the forging blank, which is far superior to the prior art.

[0026] Please also read Figures 1 to 3 Now, a vertical double-worktable double-moving forging hydraulic press provided in the embodiment of the present application is described. The vertical double-worktable double-moving forging hydraulic press comprises a lower die base 100, a platform assembly and a forging assembly. Among them:

[0027] The lower die base 100 is used to install the lower die, and the lower die can be used to accommodate the metal forging 500 after installation. The platform assembly includes a first workbench 201 and a second workbench 202 that can approach or move away from the lower die base 100 along a first direction. The second workbench 202 is located between the first workbench 201 and the lower die base 100 and has at least three through holes 221 evenly distributed along a second direction. The first direction is perpendicular to the second direction. The forging assembly includes a first sliding die base 301 slidably connected to the first workbench 201 and a second sliding die base 302 slidably connected to the second workbench 202. The first sliding die base 301 and the second sliding die base 302 are used to slide synchronously along the second direction. The first sliding die base 301 is provided with pre-forging punches 311 and forming punches 312 spaced apart along the second direction. The second sliding die base 302 is provided with two through holes 321 corresponding to the pre-forging punches 311 and the forming punches 312. The lower end surface of the second sliding die base 302 is provided with two through holes 321 corresponding to the pre-forging punches 311 and the forming punches 312. 1 is coaxially divided into two parts for installing the pre-forging upper die and the forming upper die. During the pre-forging process, the pre-forging upper die can be matched with the lower die on the lower die seat 100 to close the die, thereby closing and supporting the blank of the metal forging 500. The pre-forging is formed under the action of the pre-forging punch 311. After the pre-forging process is completed, the forming upper die is transferred to the upper part of the lower die and closed, thereby closing and supporting the pre-forging blank of the metal forging 500. The final forming of the metal forging 500 is completed under the action of the forming punch. In this process, the pre-forging blank does not need to be taken out from the lower die, saving production time. In this embodiment, the spacing between the through holes 221 is equal to the spacing between the pre-forging punch 311 and the forming punch 312 and the distance between the through holes 321. Here, the pre-forging upper die and the forming upper die are respectively formed with holes for the pre-forging punch 311 and the forming punch 312 to pass through.

[0028] According to the above structure provided in this embodiment, the pre-forging punch 311 and the forming punch 312 are fixed together on the first sliding die base 301 in this embodiment. When the metal forging 500 needs to be pre-forged, the blank of the metal forging 500 can be fixed by firstly cooperating the pre-forging upper die with the lower die on the lower die base 100. The pre-forging punch 311, driven by the first workbench 201, passes through the through hole 221 in the middle and the through hole 321 corresponding to the pre-forging punch 311 to pre-forge the blank of the metal forging 500, and the forming punch 312 can be temporarily accommodated in the through hole 221 on the side to avoid interference with the second workbench 202. After the pre-forging process is completed, it is only necessary to reset the first workbench 201 and the second workbench 202 and make the first sliding die seat 301 and the second sliding die seat 302 slide synchronously along the second direction, so that the forming punch 312 can form and punch the pre-forged blank in the upper and lower dies after the molds are closed through the through hole 221 in the middle and the through hole 321 corresponding to the forming punch 312, and the pre-forging punch 311 can be temporarily accommodated in the through hole 221 on the other side to avoid interference with the second workbench. Therefore, during the stamping process of the metal forging 500, there is no need to frequently replace the punch head and take the forging blank out of the lower die, and the metal forging 500 can be formed with only one lower die, which greatly improves the forging efficiency of the hydraulic press and is far superior to the existing technology.
