Problems solved by technology

In the existing pull-down forging press, four sets of upper anvil clamping and quick-change mechanisms need to be installed on the four corners of the upper beam to realize a single upper anvil clamping and quick-change function, but it is impossible to realize the function of upper anvil rotation. Function
These devices are complex in structure, occupy a large space, involve many parts, are inconvenient to manufacture, install and maintain, and have a high failure rate of equipment, which seriously affects production efficiency; at the same time, the installation of these devices greatly increases the complexity of press design. sex, which seriously weakens the strength of the upper beam of the forging press and shortens the service life of the press

Embodiment 1

[0021] Such as figure 1 As shown, the disc spring type upper anvil clamping, rotation and quick change system 101 for the pull-down forging press is installed in the center of the upper beam 104 of the forging press through a stud 102 and a first nut 103 .

[0022] The upper anvil backing plate 106 and the upper beam 104 are connected together through a key 105 and a first connecting screw 107 . The upper anvil 111 and the upper anvil connecting seat 109 are connected together by the second connecting screw 110 . Four evenly distributed keys 108 are arranged between the upper anvil 111 and the upper anvil backing plate 106 .

[0023] The T-shaped head end of the T-shaped tie rod 212 in the disc spring type upper anvil clamping, rotation and quick change system 101 for the pull-down forging press is installed in the groove of the upper anvil connecting seat 109, so that the upper anvil 111 The bottom surface and the last anvil backing plate 106 are closely attached together. ...

Embodiment 2

[0025] Such as figure 2 and image 3 As shown, the lower cylinder 201 of the upper anvil is connected with the upper beam 104 of the forging press through a stud 102 and a first nut 103 .

[0026] The upper anvil clamping mechanism in the form of a disc spring set is adopted. The T-shaped tie rod 212 is connected with the piston 203, the first bearing 204, the second bearing 207, the keyed gear 205, the slider 210, the disc spring set 211 and the support through the second nut 202. The seat 213 is connected together, which ensures the consistency of the up and down movement of the T-shaped tie rod 212 and other components.

[0027] A boss is processed on the bottom of the lower cylinder 201 on the upper anvil, which acts as a stroke limiter for the downward movement of the piston 203.

[0028] The arrangement of the first bearing 204 and the second bearing 207 makes the piston 203, the slide block 210, and the disc spring group 211 remain stationary during the rotation of t...

Abstract

The invention belongs to the technical field of forging devices and relates to a disk spring type upper anvil clamping, rotating and rapid exchanging system for a pull-down type forging press. The system is characterized by at least comprising a disk spring group type upper anvil clamping mechanism and an upper anvil rotating mechanism which are fixedly installed on a centre line of an upper beam of the forging press, and the system is fixedly connected with the upper beam of the forging press; the upper anvil clamping mechanism at least comprises an upper anvil press cylinder, a T-shaped pull rod, a disk spring group, a piston, a second screw nut, a sliding block, a supporting seat and a key gear, a T-shaped head end portion of the T-shaped pull rod is installed in a groove of an upper anvil connection seat and performs up and down reciprocating motion along a centre line of the upper anvil press cylinder, and the key gear is arranged on the T-shaped pull rod; and according to the upper anvil rotating mechanism, a rack type piston rod is arranged in an upper anvil rotating oil chamber of the system and meshed with the key gear. According to the disk spring type upper anvil clamping, rotating and rapid exchanging system for the pull-down type forging press, three functions of clamping, rotating and rapid exchanging of an upper anvil of the forging press are integrated.

Description

technical field [0001] The invention belongs to the technical field of forging equipment, and relates to a disc spring type upper anvil clamping, rotating and quick changing system for a pull-down forging press. Background technique [0002] Most of the existing pull-down forging presses are three-beam and two-column structures. The press frame composed of upper beam, lower beam and column moves up and down along the guide device of the fixed beam to realize the forging function. An upper anvil backing plate and an upper anvil are installed at the center of the lower surface of the upper beam. Due to the needs of the forging process, especially when performing forging processes such as upsetting, elongating, rounding, bending, and straightening, it is often necessary to realize the rotation of the upper anvil and frequently replace different types of upper anvils. In the existing pull-down forging press, four sets of upper anvil clamping and quick-change mechanisms need to...
