Abstract
The invention relates to a secondary trimming method for a die. Specific trimming procedures are that a lower-die trimming knife is matched with an upper-fie trimming knife, whole waste material is cut along a trimming line, the cut waste material slides down to a cutting edge of a lower-die waste material knife along a waste material rod, an upper die moves upward, trimmed components are taken away, then a next drawing component is put in, a lower die moves downward until the die is closed again, an upper-die waste material knife also moves downward and cuts a previous waste material matched with the lower-die waste material knife and slides out of the die while the upper-die trimming knife and the lower-die trimming knife trim the drawing component, at the same time, the entire waste material cut by the trimming knife slides to the cutting edge of the lower-die waste material knife again through the waste material rod at the same time, and circulation is conducted in this way. According to the technical scheme of the secondary trimming method for the die, the trimming quality can be guaranteed, and at the same time trimming can not be influenced by the size of the waste material.
Description
Technical field
The invention belongs to technical field of mold, refer to a kind of secondary trimming method of mould especially.
Background technology
In process of production, deburring is inevitable operation during mould is produced to mould, in order to ensure the normal production of mould, generally on manual production line, requires that the waste material produced during deburring can skid off mold exterior; And in automatic production line, require that waste material can skid off outside lathe.Object outside mold exterior or lathe can be skidded off to realize waste material, existing technology takes to increase reject chute, increase mold height, add the modes such as lastics pin, but the increase of these above-mentioned structures still requires that the size of waste material can not be excessive, require that the catercorner length of waste material is no more than 450-600mm under normal circumstances.
The effect of edge iron is that the drawn component obtained after drawing excises waste material, obtains predetermined parts profile, and waste knife is then again cut off by the waste material cut away by edge iron, by the size Control of waste material in the scope required, to ensure skidding off of waste material.
As shown in Figures 1 to 4, being the structural representation of edge iron and waste knife in existing technical scheme, is that between edge iron and waste knife, gapless is fixed together to use in existing technology, and namely the waste knife 4 of edge iron 3 and the patrix of patrix integrally; The edge iron 1 of counterdie and the waste knife 2 of counterdie are integrally.When mould closes, trimming process step carries out with cut-out waste material operation simultaneously.There is following shortcoming in such structure &processes:
1, edge iron and waste knife splicing the product edge after deburring can leave machined trace, are difficult to ensure deburring quality.
2, require higher to the splicing gap between edge iron and waste knife, increase the assembling difficulty of also cutter block, extend Making mold and maintenance period.
3, because waste knife is arranged on the passage of waste material downslide, interference-free during for ensureing that waste material glides, need the careful position that waste knife is set, sometimes also local deburring is wanted, residue waste material will continue deburring in lower operation, complex process, and not easily ensures deburring quality.
Summary of the invention
The object of the invention is to propose improvement opportunity scheme to the secondary trimming method of existing mould, deburring quality can not only be improved by the technical program, and not by the restriction of waste material size.
The present invention is achieved by the following technical solutions:
