Abstract
The utility model relates to a thickness strenghthened type blanking drift, by the thickening upper punch, drift in the thickening, thickening low punch and terminal drift are constituteed, wherein, the thickening upper punch that is arranged in the top is connected with the thickening drift, the drift is connected through first arc portion with the thickening low punch in the thickening, thickening low punch and terminal drift are connected through second arc portion, the thickness size order of each drift of blanking drift is for thickening the upper punch, drift in the thickening, the thickening low punch, terminal drift, the length size order of each drift of blanking drift in for the thickening, the thickening low punch, the thickening upper punch, terminal drift. The utility model discloses a thickness strenghthened type blanking drift strengthens through the local thickness to the blanking drift, and the loss of blanking in -process to the drift that has significantly reduced has lengthened the life of blanking drift.
Description
Technical field
The utility model belongs to machined die field, is specially the reinforced blanking punch of a kind of thickness.
Background technology
In electronic die production process, often can run into the thinner blanking die of some materials, the width of blanking punch is often also little than material thickness, and if material thickness is the copper material of 1.0mm, the width of blanking punch is only 0.7mm.The width of blanking punch is less than material thickness, and in process of producing product, this type of blanking punch easily fractures, and service life is low, increases, so both add the cost of mould to the loss of blanking punch, have impact on again the normal production of product.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of thickness reinforced blanking punch, by strengthening the local thickness of blanking punch, greatly reducing the loss for drift in blanking process, extending the service life of blanking punch.
The utility model solves its technical problem and is achieved through the following technical solutions:
The reinforced blanking punch of a kind of thickness, by thickening upper punch, drift in thickening, thicken low punch and end drift composition, wherein, the thickening upper punch being arranged in top is connected with thickening drift, in thickening, drift is connected by the first curved portions with thickening low punch, thicken low punch to be connected by the second curved portions with end drift, the thickness size order of each drift of blanking punch is for thickening upper punch, drift in thickening, thicken low punch, end drift, the length scale order of each drift of blanking punch is drift in thickening, thicken low punch, thicken upper punch, end drift.
In described thickening upper punch, thickening, the thickness proportion of drift, thickening low punch and end drift is 5.5:4.7:2.7:0.7, and thickening drift in upper punch, thickening, thickening the length ratio of low punch and end drift is 7:43:11:4.
In described thickening upper punch, thickening, the thickness of drift, thickening low punch and end drift is respectively 5.5mm, 4.7mm, 2.7mm and 0.7mm.
In described thickening upper punch, thickening, the length of drift, thickening low punch and end drift is respectively 7mm, 43mm, 11mm and 4mm.
The beneficial effects of the utility model, by strengthening the local thickness of blanking punch, greatly reducing the loss for drift in blanking process, extending the service life of blanking punch.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is upward view of the present utility model.
Number in the figure is described as follows:
1-thickeies upper punch; Drift during 2-thickeies; 3-first curved portions; 4-thickeies low punch; 5-second curved portions; 6-end drift.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The reinforced blanking punch of thickness as shown in drawings, be made up of drift 2, thickening low punch 4 and end drift 6 in thickening upper punch 1, thickening, wherein, the thickening upper punch being arranged in top is connected with thickening drift, in thickening, drift is connected by the first curved portions 3 with thickening low punch, thickeies low punch and is connected by the second curved portions 5 with end drift.
In described thickening upper punch, thickening, the thickness of drift, thickening low punch and end drift is respectively 5.5mm, 4.7mm, 2.7mm and 0.7mm.In described thickening upper punch, thickening, the length of drift, thickening low punch and end drift is respectively 7mm, 43mm, 11mm and 4mm.
During work, under the entirety of electronic die drives, blanking punch carries out stamping-out to material downwards; owing to having carried out thickness reinforcement to blanking punch; therefore drift not frangibility in blanking process, can carry out stamping-out to material very smoothly, thickeies the position head that liquidates and serves good protective effect.
Above exemplary description is done to the technical solution of the utility model; should be noted that; when not departing from the core of the technical program, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into the protection domain of this patent.
