Description

A kind of valve plate aperture stamping procedure merging device

Technical field

The utility model belongs to auto parts and components field, and especially a kind of valve plate aperture stamping procedure merges device.

Background technology

The stamping parts type of auto parts and components is various, and most of is all stamping parts, and has many apertures in product（This practicality Novel product is 1.7 through-holes of φ）It needs to process, difficult point is：It is influenced due to mould structure and punch intensity, it is primary to rush The mold frequent breakage at aperture position when molded, can not carry out volume production, and traditional handicraft first rushes the rest part in addition to aperture Molded, mold changing again is completed to rush the technique of aperture, and this processing method occupies excessive equipment manpower, and corrective maintenance mould It is longer and machining period is long to have a maintenance period, wastes a large amount of time, needs repeatedly to have enough to meet the need in process, leads to a large amount of half Finished product is accumulated, and inventory increases, and is not suitable for high-volume continuous work.During producing at the scene, part punching has very sharp burr, The hand for the worker having gloves on to scratching, is caused serious industrial injury by the regular meeting of these burrs, is all made to personal and company At serious loss.

Utility model content

In order to overcome existing valve plate aperture stamping procedure that need to repeatedly be punched existing technical deficiency, the utility model provides one The shortcomings that kind valve plate aperture stamping procedure merges device, which overcomes multiple working procedure to bring error, once-combined blanking is completed Product are rushed, multiple working procedure is merged, improve production efficiency, reduce the cost manually brought, avoid what multiple bearing was brought Error, and can be with binder in blanking process, workpiece is more smooth, and to solve the problems, such as that position degree fluctuates big, improves product quality Stability indirectly improves the economic benefit of company.

The utility model solve its technical problem the technical solution adopted is that：A kind of valve plate aperture stamping procedure merging dress It sets, including the first mandril, the second mandril, cylinder, concave-convex mold, 1.7 bore of the punch of concave template, punch retainer and φ；First mandril Lower section connects cylinder；The second mandril is connected below cylinder；Concave-convex mold is equipped at left and right sides of second mandril；Below second mandril face Equipped with 1.7 bore of the punch of φ；1.7 punch bore ends of φ are 5 bore of the punch of φ by R10 rounding off transition；Among 5 bore of the punch of φ Vertical direction is equipped with concave template；Connect punch retainer below concave template, 1.7 bore of the punch of φ sequentially passes through punch retainer and recessed Template-setup.

It installs 4 12 positioning pins of φ additional between punch retainer and concave template, ensures the cooperation precision in hole between two plates, adopt With 12 C+0.005mm of low-speed WEDM dowel hole 4* φ, to ensure punch during mold work punch always with Concave template is vertical.

Position degree between concave-convex mold is precisely positioned using 4 20 outer guiding posts of φ, the same dowel hole of processing technology Processing method uses 12 C+0.005mm of low-speed WEDM dowel hole 4* φ.

In use, starting cylinder, the first mandril and the second mandril is driven to operate by cylinder, by punch retainer and cavity plate The cooperation precision that 4 12 positioning pins of φ ensure hole between two plates is installed between plate additional, using low-speed WEDM location hole 4* φ 12 C+0.005mm, to ensure punch, punch is always with female vertical during mold work, the position degree essence between concave-convex mold Standard is positioned using 4 20 outer guiding posts of φ, and processing technology uses 12 C+ of low-speed WEDM dowel hole 4* φ 0.005mm.Change traditional punch structure in terms of punch, punch body middle and back is thicker, and intensity increases；Head is used from φ 5 to φ The radial pressure of φ 1.7 is dispersed into φ 5 by 1.7 R10 rounding ofves, and radial pressure reduces by 60% in the middle part of punch, realizes one Road punching press is completed.

The utility model has the beneficial effects that a kind of valve plate aperture stamping procedure merges device, multiple working procedure is not only overcome The shortcomings that bringing error, once-combined blanking completion rush product, multiple working procedure are merged, production efficiency is improved, reduce artificial The cost brought avoids the error that multiple bearing is brought, and can be with binder in blanking process, and workpiece is more smooth to solve position Degree of setting fluctuates big problem, changes traditional punch structure in terms of punch, and punch body middle and back is thicker, and intensity increases, and head uses The radial pressure of φ 1.7 is dispersed into φ 5 by the 1.7 R10 rounding ofves from φ 5 to φ, and radial pressure reduces in the middle part of punch 60%, to improve its service life, realize that one of punching press is completed.The stability of product quality is improved, the economy of company is indirectly improved Benefit.
