Description

Thickness material continuous stamping die

Technical field

This practicality is related to metal forming mold field, more specifically, it relates to a kind of thick material continuous stamping die.

Background technology

Punch forming process is to apply external force to fixed plank, tubing in a mold etc. by forcing press, makes its generation Deformation or separation, to be made required shape, size and performance workpiece method for processing forming.Punch forming process has speed Spend feature fast, of large quantities.Diel is to be used for stamping forming mold, in the batch production of high speed, diel Structure, precision can have a direct impact the quality and production efficiency of stamping parts.

In the prior art, since diel has stronger specificity, when product structure is complex, need to pass through punching When multiple processes such as sanction, drawing and bending, often different molds is utilized to realize corresponding process；This will develop more cover dies Tool, causes to be connected defective tightness between each process, reduces production efficiency.

Utility model content

In view of the deficiencies of the prior art, this practical purpose is to provide a kind of thick material continuous stamping die, has primary The high efficiency of multiple processes is completed in punching course.

To achieve the above object, this practicality provides the following technical solutions：

A kind of thick material continuous stamping die, including upper die holder and lower die holder；The upper die holder is fixedly connected with upper padding plate, institute It states upper padding plate and is fixedly connected with upper clamp plate；The lower die holder is fixedly connected with lower bolster；It is characterized in that：It further include middle template； The middle template is connect with the upper clamp plate by contour set component one, is fixed on the upper die holder and is supported with the middle template The elastic component connect；Several stripper plates are fixedly connected in the middle template, is fixed on the upper clamp plate and several wears institute State the punch assemblies of middle template and the stripper plate；Be fixedly connected on the lower bolster under the quantity such as the stripper plate Template；In molding, the stripper plate and the lower template compress metallic strip.

So set, upper clamp plate is used for solid punch component, the setting of upper padding plate and lower bolster makes in punching course, Middle template, stripper plate and lower template are more uniformly stressed；In molding, it is threaded through punch assemblies on each stripper plate simultaneously Different stamping procedures is completed to metallic strip；Template detaches to make with upper clamp plate during the setting of elastic component makes in die sinking Stripper plate scrapes metallic strip from punch assemblies；To improve production efficiency.

Further setting：The punch assemblies include piercing punch and drawing punch-pin；Confession is offered in the lower template The material-dropping hole that the piercing punch passes through, in the lower template being equipped with cavity plate enters block, enters in the cavity plate and is offered on block The forming hole stretched into for the drawing punch-pin.

So set, passing through, piercing punch and drawing punch-pin are set so that in a punching course to metallic strip into Row punching and extrusion forming improve processing efficiency.

Further setting：The piercing punch includes punch, punch mandril and ram block；In the upper of the upper die holder End face offers mounting groove, and the ram block is secured by bolts in the mounting groove；The punch mandril wears described Upper die holder and the upper padding plate, the upper end are abutted with the ram block；The punch wears the upper clamp plate, the upper end and institute The bottom end for stating punch mandril abuts.

So set, cushion block is used for pressure transmission to punch mandril, power is transferred to punch by punch mandril again, to make Puncture motion is completed in punch indentation dumping pit；The setting of punch mandril shortens the length of punch simultaneously, makes it in stress With higher stability.

Further setting：It is equipped with buoyant block in the lower template, the buoyant block and wears the lower bolster and institute State the reset assembly connection of lower die holder.

So set, by the way that buoyant block is arranged so that metallic strip is jacked up by buoyant block after die sinking, is convenient for metallic strip Conveying；Reset assembly makes buoyant block that can be pressed into lower template after molding without interfering punching press action.

Further setting：The reset assembly includes contour set component two, spring and stud bolt；On the lower die holder The mounting hole for accommodating the spring is offered, the contour set component two is connect with the buoyant block and its lower end passes through institute It states lower bolster and stretches into the mounting hole；The threaded hole being connected to the mounting hole is offered in the lower face of the lower die holder, The threaded hole connects the headless screw, the both ends of the spring respectively with the headless screw and the contour set component two It abuts.

So set, contour set component two plays the role of accurately being oriented to the movement of buoyant block, by by itself and spring It abuts so that buoyant block can realize that when that metallic strip is jacked up and molded when die sinking enters lower die under the action of the spring Plate.

Further setting：The pilot pin for wearing the stripper plate is fixed in the middle template, in the lower template It is provided with the correcting hole for the pilot pin grafting.

Be arranged such so that in each punching press, metallic strip under the action of pilot pin can accurately with stripper plate It is aligned with the station in lower template, to ensure the precision of punch process.

Further setting：Several positioning pins one is interspersed in the middle template and the stripper plate.

So set, by adding positioning pin one so that the positioning of middle template and stripper plate when mounted is more accurate, from And ensure that wearing punch assemblies therein moves smooth accurate, raising punching precision.

Further setting：Several positioning pins two is interspersed in the cope plate, the upper padding plate and the upper die holder.

So set, by adding positioning pin two so that the positioning of cope plate, upper padding plate and upper die holder when mounted is more Accurately, to which the position of the punching and punching press that ensure is accurate, punching precision is improved.

Further setting：Several positioning pins three is interspersed in the lower template, the lower bolster and the lower die holder.

So set, by adding positioning pin three so that the positioning of lower template, lower bolster and lower die holder when mounted is more Accurately, to which the position of the punching and punching press that ensure is accurate, punching precision is improved.

In conclusion this practicality has the advantages that：

1. multiple stations work at the same time in a clamping process, multiple molding procedures are carried out to metallic strip, to carry High production efficiency；

2. the corresponding stripper plate of each process and lower template can be changed individually, it is easy for installation and maintenance；

3. mould structure movement is accurate reliable, product processing quality is unified to be stablized.
