Abstract
The utility model provides an air blowing type energy-saving numerical-control turret punch press mold. The mold comprises a punch, a double-layer punch mold and a guide sleeve, wherein a stop ring, an oil ring, a demolding spring and a demolding spring outer shield are arranged at the upper part of the punch sequentially from bottom to top; the double-layer punch mold is movably arranged at the top end of the punch and contacted with the demolding spring outer shield; the guide sleeve is arranged on the outer side of the punch, a connecting gap is formed between the inner side surface of the guide sleeve and the outer side surface of the punch, an oil guide hole communicated with the connecting gap is formed in the top end of the punch, and an oil discharge hole is formed in the bottom of the guide sleeve. During usage of the mold, lubricating oil is blown into the oil guide hole through air pressure to act in the connecting gap between the punch and the guide sleeve, so that the punch and the guide sleeve are fully lubricated and cooled, and abrasion is reduced; the oil discharge hole is formed in the bottom of the guide sleeve, the lubricating oil is ejected via the oil discharge hole to directly act on a to-be-machined plate, phenomena of plate hanging and material jumping are reduced, the machining accuracy and the machining quality of products are improved, and the rejection rate is decreased.
Description
Technical field
The utility model relates to a kind of digital turret punch die, specifically a kind of numerically controlled rotating tower punch mould of air-sweeping type.
Background technology
At present, known digital turret punch die is made up of the nose of punch, de-material spring, stop ring, oil ring, drift and guide pin bushing.This mould is in the time of processing steel plate; due to the die-cut speed very high (per minute reaching more than 800 times) of NC turret punch machine; lubrication does not catch up with; often there will be the phenomenon of drift wearing and tearing; also there will be link plate simultaneously, jump the phenomenon of expecting; under summer high-temperature, work long hours, also can cause burst-mode phenomenon, make the phenomenon that is not durable of mould very obvious.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, and a kind of numerically controlled rotating tower punch mould of air-sweeping type is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of numerically controlled rotating tower punch mould of air-sweeping type; comprise drift, double-deck drift mould and guide pin bushing; described drift top is disposed with stop ring, oil ring, ejector spring and ejector spring outer shield from bottom to top; described double-deck drift mould is movably arranged on drift top; contact with ejector spring outer shield; described guide pin bushing is set in drift outside, and forms joint gap between the medial surface of described guide pin bushing and the lateral surface of drift, and the top of described drift offers the oil guiding hole communicating with joint gap.
Described oil guiding hole comprises the first oil guiding hole and the second oil guiding hole, and described the first oil guiding hole is arranged on the top center position of drift, and the bottom of the first oil guiding hole is connected with the second oil guiding hole; Described the second oil guiding hole is arranged on the side of drift, is connected with joint gap.
The bottom of described guide pin bushing offers oil outlet.
Described double-deck drift mould is threaded with drift.
Compared with prior art, the beneficial effect producing is the numerically controlled rotating tower punch mould of a kind of air-sweeping type of the present utility model:
The utility model is reasonable in design, in use procedure, lubricating oil is blown in oil guiding hole by air pressure with special purpose device, make in its joint gap that acts on drift and guide pin bushing, make drift and guide pin bushing obtain sufficient lubrication, greatly reduce wearing and tearing, extended the service life of mould; On the other hand, bottom at guide pin bushing sets out oilhole, because drift top is provided with oil ring, so the lubricating oil being blown into can only be by the oil outlet ejection of guide pin bushing bottom, then act on the sheet material of processing, greatly reduce link plate, jump material phenomenon, improved machining accuracy and the quality of product, reduced defective products rate.
