Channel tie is manufactured one-time-shaped mould
Technical field
The utility model relates to flute profile pull bar manufacturing technology field, is specifically related to a kind of channel tie and manufactures one-time-shaped mould.
Background technology
In the time of current traditional processing and manufacturing channel tie, adopting processing technology is with oxygen and acetylene, to cut gas cutting to obtain corresponding shape.The shortcoming that this technique exists is that operation is various, and the product appearance processing is not attractive in appearance; Processing cost is high, and workman labour is large, and production efficiency is low; Operator's skills involved in the labour are also had to higher requirement; In process, there is certain danger.
Utility model content
The purpose of this utility model is to provide a kind of channel tie and manufactures one-time-shaped mould, the utility model manufacture a product cost low, easy to use, without any danger, production efficiency high.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises upper die and lower die, and the cut out portion of patrix is circular shape, and counterdie is fixed on the workbench of punch press, and patrix is connected on punch press transmission push rod.The utility model manufacture a product cost low, easy to use, without any danger, production efficiency high.Its punching press shape of product is out perfect, steady quality, at the patrix of diel, have and adopted certain improvement in addition, patrix cut out portion causes arcuation, in punching course, what upper and lower mould adopted is that wire is sheared, rather than planar shearing, so the supporting punch press tonnage demand of mould is reduced greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, it comprises upper die and lower die, and the cut out portion of patrix is circular shape, and counterdie is fixed on the workbench of punch press, and patrix is connected on punch press transmission push rod.
Operation principle: the utility model, mainly for the dovetail groove processing of channel tie, changes the processing method of gas cutting for tradition, implements punching press one-shot forming; Channel tie punch press one-time-shaped mould is mainly comprised of upper and lower mould, and counterdie is fixed on the workbench of punch press, and patrix is connected on punch press transmission push rod; The cut out portion of patrix is designed to circular shape, rather than plane, upper and lower mould is that what first to contact is circular arc wire cutting edge part carrying out shearing, patrix declines workpiece is sheared and opened after a part, then all decline and enter shearing, can reduce significantly the requirement to punch press tonnage like this.
Utility model manufacture a product cost low, easy to use, without any danger, production efficiency high.Its punching press shape of product is out perfect, steady quality, at the patrix of diel, have and adopted certain improvement in addition, patrix cut out portion causes arcuation, in punching course, what upper and lower mould adopted is that wire is sheared, rather than planar shearing, so the supporting punch press tonnage demand of mould is reduced greatly.
