Abstract
The invention relates to the technical field of plate machining dies, in particular to a plate, a plate trimming die and a plate trimming process. The plate trimming die provided by the invention comprises a lower die base which is provided with waste discharge parts. The waste discharge parts are located below the to-be-removed edges of the plate. Part of waste generated after trimming of the plate can be discharged in time through the waste discharge parts, thus, the waste can be prevented from being blocked by guide post bases of the lower die base, and the phenomenon that blockage is caused since all waste is discharged through cut holes and accumulate at the bottom of the lower die base in the prior art can be avoided. Accordingly, the trimming procedure of the plate can be completed through one-time cutting, the production efficiency is greatly improved, and the requirement of an enterprise for scale production is met.

Step b, sheet material is carried out trimming:
Pretreated sheet material being positioned over the top of described mould, then sheet material carry out stamping-out, the little scrap that cut edge is formed is discharged with cutting hole by waste material drain member respectively.
Compared with prior art, the application provides the benefit that:
The sheet material that the application provides, scrap region is treated including edge to be excised with described edge is connected, described edge at least two breach, and breach all deeply to described in treat the junction of scrap region and described edge, after making described edge cut, become several little scraps being not susceptible to putty.
The sheet material shaving die that the application provides; including die shoe; die shoe is provided with waste material drain member; waste material drain member is positioned at sheet material and treats the lower section of margins of excision; the waste material part that sheet material produces after trimming can be discharged in time by waste material drain member; waste material can either be avoided to be blocked by the guide pillar seat of die shoe; can solve the problem that again prior art waste material all accumulates in the putty phenomenon caused bottom die shoe by cutting hole discharge; thus the trimming operation of sheet material just can be completed by stamping-out; it is greatly improved production efficiency, meets the demand that enterprise scale produces.
The sheet material trimming technology that the application provides, it is possible to effectively solve putty phenomenon, thus the trimming operation of sheet material just can be completed by stamping-out, it is greatly improved production efficiency, and operation is simple, it is easy to operate.

Detailed description of the invention
With the following Examples the application is further described.
The sheet material that the present embodiment provides, as it is shown in figure 1, be rectangle.In sheet material 8, dotted line wire frame A is with inner region for treating scrap region, for edge to be excised outside dotted line wire frame A.14 breach 81 of edge to be excised, each breach 81 is all deeply to the junction treating scrap region and edge to be excised so that after described edge is cut, form 14 little scraps being not susceptible to putty.
The sheet material shaving die that the present embodiment provides, as shown in Figure 2, Figure 3, Figure 4, including bottom plate 1, is connected by lower cushion block 2 between die shoe 3 with bottom plate 1.The top of die shoe 3 is connected with lower bolster 4, lower plate 5, lower bolster 6 and lower de-plate 7 in turn.Sheet material 8 is placed in above lower de-plate 7.Longer two edges of lower bolster 4 are respectively connected with four guide pillar seats 10.
See Fig. 2, the position at four angles of the corresponding sheet material 8 of die shoe 3, and longer two positions treated in the middle part of margins of excision of corresponding sheet material 8 be equipped with and cut hole 31(and amount to 6 and cut hole 31).It addition, see Fig. 2, Fig. 3, Fig. 4 in the lump, the lower section at the edge that sheet material 8 is to be excised is provided with waste sliding plate 9(as waste material drain member), waste sliding plate 9 is located at adjacent two and cuts between hole 31.One end of waste sliding plate 9 is fixed in die shoe 3(by screw and sees Fig. 5), the other end of waste sliding plate 9 extends to lower bolster 6, thus forms ramped shaped.The edge of lower bolster 4 and die shoe 3 all has the placing trough (not shown) placed for waste sliding plate 9, and placing trough makes waste sliding plate 9 can be pressed firmly against lower bolster 4 and the respective edge of die shoe 3.
Owing to four of sheet material 8 treat that margins of excision is all offered breach 81(and seen Fig. 1) so that the waste material that sheet material 8 produces after a trimming is separated into 14 little block.Four angles and its longer two that are positioned at sheet material 8 treat that the waste material (totally six little block) at margins of excision each middle part is by cutting hole 31 toward falling；The waste material (totally eight little block) being positioned at remaining position, sheet material 8 edge slides to beyond die shoe 3 from the surface of each waste sliding plate 9, thus realize by a trimming, just can complete the trimming operation of sheet material 8, and the waste material produced after trimming is block in the small pieces separated, thus avoids waste material to be blocked (see Fig. 2, Fig. 5) by guide pillar seat 10.Part waste material is discharged by waste sliding plate 9 so that the waste material of this part will not drop down onto die shoe less than 3, thus reduce waste material and accumulate in this position, causes putty, thus improves production efficiency.
The sheet material trimming technology that the present embodiment provides, comprises the following steps: step a. carries out pretreatment to sheet material 8:
At 14 breach 81 of edge that sheet material 8 is to be excised, and each breach 81 is all deeply to edge to be excised and the described junction treating scrap region, making sheet material 8 after a trimming, the waste material that cut edge is formed is divided into several little scraps being not susceptible to putty；
Step b. carries out trimming to sheet material 8:
Pretreated sheet material 8 being positioned over the top of described mould, then sheet material 8 is carried out stamping-out, the little scrap that cut edge is formed is respectively by waste sliding plate 9 with cut hole 31 and discharge.
Finally should be noted that; above example is only in order to illustrate the technical scheme of the application; rather than the restriction to the application protection domain; although having made to explain to the application with reference to preferred embodiment; it will be understood by those within the art that; the technical scheme of application can be modified or equivalent, without deviating from the spirit and scope of technical scheme.
