A kind of wire cutting equipment suitable for processing the stress groove of connecting rod expansion

Abstract

The invention discloses wire cutting equipment suitable for machining a connecting rod expansion stress groove. The wire cutting equipment comprises a control cabinet, a shell is arranged at the top of the control cabinet, a bottom plate is arranged at the inner bottom of the shell, a vertical plate is arranged at the top of the bottom plate, a mounting groove is formed in the bottom of the vertical plate in a penetrating mode, a first guide wheel seat is arranged at the inner top of the mounting groove, a second guide wheel seat is arranged at the inner bottom of the mounting groove, a secondguide wheel assembly is arranged inside the second guide wheel seat, a wire vertical rod is arranged on one side of the top of the vertical plate, and a connecting rod fixing mechanism matched with the vertical plate is arranged on the top of the vertical plate and located on the outer side of the bottom of the wire vertical rod in a sleeved mode. The equipment has the beneficial effects that through using of the equipment, the groove cutting depth can be freely adjusted according to the expansion effect through the equipment, the quality of the expansion section can be used for adjusting parameters, so that the corresponding effect is achieved, the stress groove is convenient and fast to machine, the machining precision is accurate and safe, and the cost is saved.

Description

technical field [0001] The invention relates to the field of cutting equipment, in particular to a wire cutting equipment suitable for processing the expansion stress groove of a connecting rod. Background technique [0002] Expansion connecting rod is a newly emerging connecting rod processing technology in recent years. Its principle is to use a non-quenched and tempered steel as the material of the connecting rod, which not only ensures the relevant performance of the connecting rod, but also requires a certain degree of brittleness. The big head hole is designed in the form of expansion. [0003] Expansion of the connecting rod is to process a stress groove in the big head hole of the connecting rod, and use a special expansion device to break a whole big head hole into two semicircular holes, and the expansion section forms an uneven surface, and then the connecting rod bolts The uneven surfaces are reassembled together. This process not only reduces the increased proc...
