Description

It is double to cut edger

Technical field

Edger is the utility model is related to, more particularly to a kind of pair is cut edger.

Background technology

Overlap refers to that metal unnecessary in forging die thorax during die forging flows into flash gutters and forms the circle gold around forging surrounding Category, has the function that to ensure that metal fills up impression, it is mostly occurred on the division position of mould, must be cut after die forging Remove, overlap is cut off usually using edger.Current edger is the cut-out cutting edge of straight body formula, and excision precision is not high, generally Excision once can also remain the thick overlaps of 0.2mm afterwards, can not meet the demand of the higher product of precision requirement, secondly some productions It can be polished after product excision overlap, if the overlap of residual is thicker, the difficulty and cost of polishing can be increased.

Therefore, the prior art is defective, it is necessary to improve.

Utility model content

The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of pair is cut edger, improves the essence of trimming Degree.

The technical solution of the utility model is as follows：A kind of pair is cut edger, including：Upper die face plate, be fixed on it is described Die shank at the top of upper die face plate, it is fixed on the clamping plate of the upper die face plate bottom, is fixed on the upper die face plate bottom Portion and drift through the clamping plate, below the clamping plate and to be enclosed on the stripper plate of the drift, discharging bottom plate, installation solid It is scheduled on the second stripper of the discharging plate top surface, the first stripper installed in the second discharging plate top surface, positioned at institute State guide pillar that drift side is fixed between the discharging bottom plate and the upper die face plate, pacify positioned at the drift opposite side Fill the tapping guide pillar being fixed between the stripper plate and the discharging bottom plate, the first spring and set that are enclosed on the guide pillar Second spring on the tapping guide pillar.The first cut-out cutting edge, second stripper are provided among first stripper Centre is provided with the second cut-out cutting edge, and the first cut-out cutting edge is identical with the described second cut-out blade shape and is located at same center Line, the radial dimension of the second cut-out cutting edge is more than the radial dimension of the described first cut-out cutting edge, among the discharging bottom plate Provided with a through hole, the through hole internal diameter is more than the appearance and size of processing part, in order to which the part after punching press drops from through hole.

The second cut-out cutting edge bottom is provided with oblique angle.

Using such scheme, double cut-out cutting edges for cutting mould are changed to step by the utility model, and disposably overlap is carried out Cut off twice, both improve processing efficiency, improve machining accuracy again.

Brief description of the drawings

Fig. 1 is the utility model overall structure diagram.

Fig. 2 is the enlarged drawing that the utility model first cuts off cutting edge and the second cut-out cutting edge.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of pair and cuts edger, including：Upper die face plate 12, installation The die shank 10, the clamping plate 14 for being fixed on the upper die face plate bottom, installation for being fixed on the top of upper die face plate 12 are fixed On described the bottom of die face plate 12 and drift 20 through the clamping plate 14, below the clamping plate 14 and be enclosed on the drift Stripper plate 16, discharging bottom plate 26 on 20, it is fixed on the second stripper 24 of the top surface of discharging bottom plate 26, installed in institute State the first stripper 22 of the top surface of the second stripper 24, the discharging bottom plate 26 is fixed on positioned at the side of drift 20 with Guide pillar 18 between the upper die face plate 12, it is fixed on the stripper plate 16 positioned at the opposite side of drift 20 and is unloaded with described Expect the tapping guide pillar 28 between bottom plate 26, the first spring 30 being enclosed on the guide pillar 18 and be enclosed on the tapping guide pillar 28 Second spring 32.The first cut-out cutting edge 36 is provided among first stripper 22, is provided among second stripper 24 Second cut-out cutting edge 38, the first cut-out cutting edge 36 is identical with the described second cut-out shape of cutting edge 38 and is located at same center Line, the radial dimension of the second cut-out cutting edge 38 are more than the radial dimension of the described first cut-out cutting edge 36, the discharging bottom plate Be provided with a through hole among 26, the through hole internal diameter is more than the appearance and size for processing part 34, in order to the part 34 after punching press from Dropped in through hole.Second cut-out cutting edge 38 bottom is provided with oblique angle, so that the part 34 after punching press more smoothly falls into through hole In.

In summary, parts to be processed first passes through the first cut-out cutting edge and carries out initial ablation to overlap, then is cut by second Disconnected cutting edge carries out second to overlap and cut off, and double cut-out cutting edges for cutting mould are changed to step by the utility model, disposably to flying Side is cut off twice, is both improved processing efficiency, is improved machining accuracy again.

Preferred embodiment of the present utility model is these are only, is not limited to the utility model, it is all in this practicality All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
