Abstract
The utility model relates to a punching device which comprises a punching die carrier, a punching die carrier baseplate, a punch rod and a punch, wherein the punching die carrier baseplate is provided with a long waist-shaped hole, the punching die carrier is provided with a long waist-shaped hole perpendicular to the long waist-shaped hole of the punching die carrier baseplate, the piercing die carrier and the punching die carrier baseplate are fixed through a bolt passing through the two waist-shaped holes, the piercing die carrier can slide in the range of the long waist-shaped hole relative to the punching die carrier baseplate, a punching die consisting of a punch rod, the punch and a concave die is arranged on the piercing die carrier, the punch is fixed on the punch rod, the concave die is arranged below the punch, and the punch rod is provided with a reset spring through which the punch rod is lifted up. According to the utility model, a hole-drilling mode is replaced with a punching mode, so the production efficiency is high, and the machining accuracy is greatly improved; meanwhile, the punch rod is provided with a reset spring through which the punch rod can be lifted up automatically, so that the punching device disclosed by the utility model can be applied to the punching of various structural steels or steel plates.
Description
Technical field
The utility model relates to a kind of hole punched device.
Background technology
Application to shaped steel in the productive life is many, shaped steel often needs to process many holes in application process, these hole great majority are distributed on the aerofoil of shaped steel, existing processing mode all is to adopt the mode of drilling to process basically, although it is very extensive that the mode of this drilling machining hole is used, but, because the precision of drilling is lower, the surface is more coarse, and general machining accuracy is below IT10, and the surface roughness Ra value is greater than 12.5 μ m, production efficiency is also lower, therefore, boring is mainly used in roughing, for example less demanding screw hole of precision and roughness, oilhole and thread Pilot hole etc.
The utility model content
The purpose of this utility model is to provide a kind of hole punched device that can realize that the perforate precision is higher.
The purpose of this utility model is achieved through the following technical solutions; A kind of hole punched device, comprise the punching mould bases, perforating die stand plate, plunger rod and drift, have long lumbar hole on the perforating die stand plate, have the long lumbar hole perpendicular to perforating die stand plate long lumbar hole on the punching mould bases, fixed by the bolt that passes two waist holes between punching mould bases and the perforating die stand plate, the punching mould bases can slide in the long lumbar hole scope with respect to perforating die stand plate, be equipped with by plunger rod on the punching mould bases, the punch die that drift and die form, drift is fixed on the plunger rod, die is positioned at the below of drift, is provided with the back-moving spring that plunger rod is upwards promoted on the described plunger rod.
Further, described drift is fixed on the plunger rod by nut.
Further, described die is dismountable is installed on the punching mould bases.
The utility model compared with prior art its advantage is: the utility model adopts punching to replace the drilling perforate, production efficiency is high, and greatly improved machining accuracy, simultaneously at plunger rod back-moving spring is set, can make the drift automatic lifting, the utility model can be used for the punching processing of multiple shaped steel or steel plate.
Description of drawings
Fig. 1 is hole punched device structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 1 is hole punched device structural representation of the present utility model, as shown in Figure 1, a kind of hole punched device of the present utility model, comprise punching mould bases 2, perforating die stand plate 1, plunger rod 3 and drift 4, have long lumbar hole 7 on the perforating die stand plate 1, have the long lumbar hole 7 perpendicular to perforating die stand plate 1 long lumbar hole 7 on the punching mould bases 2, fixing by the bolt 6 that passes two waist holes 7 between punching mould bases 2 and the perforating die stand plate 1, punching mould bases 2 can slide in long lumbar hole 7 scopes with respect to perforating die stand plate 1, be equipped with on the punching mould bases 2 by plunger rod 3, the punch die that drift 4 and die 5 form, drift 4 is fixed on the plunger rod 3, die 5 is positioned at the below of drift 4, be provided with the back-moving spring 8 that plunger rod 3 is upwards promoted on the described plunger rod 3, described drift 4 is fixed on the plunger rod 3 by nut, described die 5 dismountable being installed on the punching mould bases 2.
In punch process, first shaped steel 9 is put into hole punched device, adjust the position of punching mould bases 2, owing to having orthogonal long lumbar hole 7 on punching mould bases 2 and the perforating die stand plate 1, so can realize simultaneously that punching mould bases 2 is mobile with respect to perforating die stand plate 1 all around, until drift 4 moved to the position that needs punching, then the bolt 6 between punching mould bases 2 and the perforating die stand plate 1 is tightened, can realize the fixing of punching mould bases 2, then get final product punching, after punching finished, the effect that plunger rod 3 is subject to back-moving spring 8 rose to height to be impacted.
The utility model adopts punching to replace the drilling perforate, and production efficiency is high, and has greatly improved machining accuracy, and the utility model can be used for the punching processing of multiple shaped steel or steel plate in addition.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
