Embodiment 1

[0084] Such as Figure 15 and Figure 16 As shown, the press for ring die punching in this embodiment includes a press body 1000 on which a press table 1001 and a briquetting block 1002 are arranged, and also includes:

[0085] A base 1, which is arranged on the upper surface of the press table 1001, and the base 1 is located directly below the pressing block 1002;

[0086] The lower punch 2 is a member with a large middle diameter and a small end diameter formed by symmetrically connecting the upper circular platform 20 and the lower circular platform 21 of the same shape;

[0087] The upper punch 3, which is in the shape of a circular platform, matches the shape of the upper circular platform 20 or the lower circular platform 21;

[0088] The lower punch placement hole 10 is opened on the upper surface of the base 1 for accommodating and fixing the lower punch 2;

[0089] The leakage hole 11 is a through hole, which is opened on the upper surface of the base 1 , and a cha...

Embodiment 2

[0099] like Figure 11 and Figure 12 As shown, the ring die punching press of this embodiment is further improved on the basis of Embodiment 1, and also includes a positioning unit 4, which is arranged on the upper surface of the press workbench 1001, and the positioning unit 4 is located on the press Below the side of block 1002, the positioning unit 4 includes:

[0100] Shaft 40, which is vertically placed on one side of base 1;

[0101] The swing rod 41 is arranged horizontally, and one end is hinged with the shaft rod 40;

[0102] The positioning block 42 is vertically connected to the bottom of the other end of the fork 41;

[0103] The positioning arm 43 is arranged horizontally, and the tail end of the positioning arm 43 is connected to the front of the other end of the swing rod 41;

[0104] After the swing rod 41 rotates at a certain angle, the positioning block 42 will contact the side of the base 1;

[0105] After the positioning block 42 is in contact with th...

Embodiment 3

[0109] like Figure 8 As shown, the ring die punching press of this embodiment is further improved on the basis of Embodiments 1 and 2, and the diameter of the leakage hole 11 gradually increases from top to bottom.

[0110] By setting the hole diameter of the leakage hole 11 to gradually increase from top to bottom, the chance of upper punch 3, lower punch 2 or part of the blank 5 being stuck in contact with the hole wall when passing through the leakage hole 11 is further reduced, and subsequent dredging is avoided. It eliminates the trouble of cleaning and improves the working efficiency of punching process.

Abstract

The invention discloses a pressing machine for ring die punching and a punching method thereof, and belongs to the pressing machine technology field. The pressing machine comprises a pressing machinebody, a substrate, a lower punch, an upper punch, a lower punch placing hole and a leakage hole, wherein the pressing machine body is provided with a pressing machine workbench and a pressing block; the substrate is arranged on an upper surface of the pressing machine workbench, and the substrate is located right below the pressing block; the lower punch is a component which is formed by symmetrically connecting an upper round table and a lower round table which are the same in shape and is large in middle diameter and small in end diameter; the upper punch is in a round table shape and is matched with the upper round table or the lower round table in shape; the lower punch placing hole is arranged in an upper surface of the substrate and is used for accommodating and fixing the lower punch; and the leakage hole is a through hole and is arranged in the upper surface of the substrate, and a lower portion of the leakage hole is connected with a cavity. The substrate is arranged below thepressing block of the pressing machine, punching operation can be completed through two times of punching and through cooperation of the lower punch and the upper punch, operation is convenient, ringdie punching machining efficiency is high, and a rejection rate is low.

Description

technical field [0001] The invention belongs to the technical field of presses, and more specifically relates to a press for ring die punching and a punching method thereof. Background technique [0002] Punching processing is a processing method in which punches or dies are used to forge holes in the blank. When forging various hollow forgings, punching is required. When forging forgings with holes, punching deformation is required in the forging die cavity. When producing ring parts by die forging on a flat forging machine, it is necessary to perform final forging and punching after gathering steps. In free forging or tire die forging, punching is a common processing procedure. [0003] The punching operation of the ring die is usually carried out on the press. When the press performs the punching process of the ring die, there are usually two methods: reverse extrusion punching and open punching (also called free punching). The two punching methods have their own advanta...
