S-shaped spring machining device

Abstract

The invention provides an S-shaped spring machining device and belongs to the technical field of machinery. The problem of low S-shaped spring production efficiency in the prior art is solved. The S-shaped spring machining device comprises a rack and a worktable arranged in the rack, wherein a straightening mechanism capable of straightening a steel wire, a forming device capable of coiling the straight steel wire to be S-shaped, a reshaping device capable of adjusting a pitch of the S-shaped spring and a cutting-off device capable of cutting off the S-shaped spring are sequentially arranged on the worktable. The forming device comprises a forming plate arranged on the worktable, a forming ring I and a forming ring II are symmetrically arranged on the forming plate, a channel for the S-shaped spring to pass through is formed between the forming ring I and the forming ring II, a forming piece is fixed to the upper portions of the forming ring I and the forming ring II, the forming plate can be connected with a reciprocating motion mechanism capable of driving the forming plate to perform reciprocating rotation, and an intermittent blocking mechanism capable of blocking advancing of the S-shaped spring in a spaced mode is arranged above the forming plate. The S-shaped spring machining device has the advantage of high S-shaped spring production efficiency.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and relates to a processing equipment of an S spring. Background technique [0002] S springs, also called serpentine springs, are widely used in sofa cushions and backs. The degree of automation in the existing technology is relatively low, resulting in low processing efficiency. After searching, for example, the Chinese Patent Literature discloses an automated serpentine spring production equipment [Patent No.: ZL201410182653.6; Authorized Announcement No.: CN103978130A]. This kind of automatic serpentine spring production equipment is characterized in that the equipment is provided with a pay-off reel, a serpentine spring bending machine, a buffer, a cutting machine, two spring conveying wheels and an automatic detection in sequence from the front process to the back process. An adjustment device, the automatic detection and adjustment device is composed of detection and adjustment equipment, a...
