Abstract

The utility model discloses a rotary punch which comprises an upper plate, a punch and a female die which is matched with the punch. A cone is positioned at the center of the lower end face of the punch. A hole down groove which is driven by a motor to rotate is arranged on the upper plate. The upper end of the punch is arranged inside the hole down groove. According to the utility model, an open pore is arranged in a part plate through rotation of the punch, so that the success rate and the opening efficiency of forming the open pore in the part plate are enhanced, and the quality and the accuracy of the product are ensured.

Description

The rotation drift

Technical field

The utility model relates to a kind of chipless forming technique, relates in particular to a kind of rotation drift.

Background technology

Factory need to be to the hole of formed product minor diameter in the development of new products, and the normal line location onboard of adopting is first after the small diameter bore that gets out the location on drilling machine, then holes, and the method needs secondary drilling just can complete, and production efficiency is extremely low.

In order to address the above problem, following patented technology has been proposed in prior art:

China Patent No. " 200820149497.3 " discloses a kind of drift, and its open day is on 08 05th, 2009.Its technical scheme comprises drift and die, is provided with a cone in the center, lower surface of drift.

But the prior art take above-mentioned patent document as representative, in actual use, still exist following defective: one, drift is directly to move downward, squeeze out pore with sharp-pointed cone on the part plate, due to everywhere stressed in different size on the part plate, and the each strength of extruding downwards of drift is the same, just easily causes whole part plate to damage, and causes the waste of material; Two, drift directly squeezes out pore with sharp-pointed cone on the part plate, when the extruding pore, easily cause pore to break on every side, and the hole wall of the pore that pushes is very coarse, affects the quality of part plate; Three, the size of extruding force is not easy to control when perforate, and perforate efficient is extremely low.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that in prior art, the station drift exists, a kind of rotation drift is provided, the utility model makes drift with rotation mode perforate on the part plate, has improved success rate and the perforate efficient of perforate on the part plate, has guaranteed quality and the precision of product.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of rotation drift, comprise cope match-plate pattern, drift and the die that is complementary with drift, the center, lower surface of drift is provided with a cone, it is characterized in that: be provided with the holddown groove by the motor-driven rotation on described cope match-plate pattern, the upper end of described drift is arranged in holddown groove.

The upper end of described drift is connected in holddown groove.

Employing the utility model has the advantage of:

one, in the utility model, described rotation drift, comprise cope match-plate pattern, drift and the die that is complementary with drift, the center, lower surface of drift is provided with a cone, be provided with the holddown groove by the motor-driven rotation on described cope match-plate pattern, the upper end of described drift is arranged in holddown groove, compare for the prior art of " 200820149497.3 " with China Patent No., the utility model is by motor-driven work, the speed of perforate is faster on the part plate, efficient is higher, and drift is with the rotation mode perforate, when having reduced perforate to the impulsive force of part plate, even on the part plate, the stressed of each position varies in size, can be to part plate injury yet, the drift rotation, the better quality in the hole of opening on the part plate, precision is higher.

Two, in the utility model, the upper end of described drift is connected in holddown groove, and this setting makes the stability of drift higher, also is convenient to install, dismantle drift.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Be labeled as in figure: 1, drift, 2, cone, 3, forming hole, 4, die, 5, the part plate, 6, holddown groove, 7, cope match-plate pattern.

The specific embodiment

A kind of rotation drift, comprise cope match-plate pattern 7, drift 1 and the die 4 that is complementary with drift 1, the center, lower surface of drift 1 is provided with a cone 2, it is characterized in that: be provided with the holddown groove 6 by the motor-driven rotation on described cope match-plate pattern 7, the upper end of described drift 1 is arranged in holddown groove 6.

In the utility model, the upper end of preferred described drift 1 is connected in holddown groove 6, but is not limited to above-mentioned set-up mode, for example also can adopt be threaded or make drift 1 and holddown groove 6 integrated moldings.

Operation principle of the present utility model is:

at first drift 1 is arranged on the drillstock of drilling machine, after making drift move up into for 1 time in the forming hole 3 of die 4, die 4 and Drilling machines bench are fixed, can carry out boring work this moment, the part plate 5 that line is located is placed on die 4, starter motor, driven by motor holddown groove 6 and drift 1 rotation are also moved to part plate 5, after to be punched portalling, drift 1 is moved up leave part plate 5, carry out the punching in other hole, until go out whole holes, this drift 1 is completed punching only to be needed once, and employing motor-driven, punching efficient is higher, the better quality of institute's punching.

Claims

1. rotation drift, comprise cope match-plate pattern (7), drift (1) and the die (4) that is complementary with drift (1), the center, lower surface of drift (1) is provided with a cone (2), it is characterized in that: be provided with the holddown groove (6) by the motor-driven rotation on described cope match-plate pattern (7), the upper end of described drift (1) is arranged in holddown groove (6).
