Background technology
Diel, be in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press, be at room temperature, utilizes the mould that is arranged on forcing press to exert pressure to material, it is produced separates or plastic deformation, thereby obtain a kind of pressure processing method of required part, diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacturing.The height of Design of Dies and manufacturing technology level, be one of important symbol of weighing a national product manufacture level height, determining to a great extent the development ability of quality, benefit and the new product of product.
Drift is the important component part on punching die, and owing to being subject to frequently great impulsive force, its requirement of strength is higher, and the design of drift also needs to meet the characteristics easily of changing.
Disclose a kind of punch device of head-exchangeable in patent [CN202725779U], comprised punch holder and drift, offered the drift groove in described punch holder; Described drift groove inwall is provided with detent; Described detent extends to the drift groove from drift groove port inner, is provided with three corners between the two ends of this detent; Described turning is rectangular in shape; Described drift is provided with the cylinder fixture block; Described cylinder fixture block is provided with the location dop; During installation, drift is fixed in detent in punch holder by the location dop.Structural design by detent, on original punch structure, drift is realized interchangeable, do not affect again drift effect in use, well solved the problem that after drift damages, integral body is scrapped, provide cost savings and resource, the rate that takes full advantage of of the material that improves, but because drift partly positions by detent, drift easily rocks in punch holder, and the punching press accuracy is affected.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and the punch device on a kind of punching die is provided, and technical problem to be solved in the utility model is realize drift detachable, and fixed.
The purpose of this utility model can realize by following technical proposal: the punch device on a kind of punching die, comprise punch holder and drift body, it is characterized in that, described punch holder has an installation cavity, described drift body can be plugged in described installation cavity, be provided with external screw thread on described punch holder outer wall, be provided with several on described drift body and can be resisted against limited block on punch holder, this punch device also comprises a nut, and described nut has the internal thread that coordinates with described external screw thread.
Operation principle of the present utility model is: the drift body is plugged in installation cavity, limited block on the drift body coordinates with punch holder, the drift body can not be rotated, can not, to the top motion of installation cavity on punch holder, utilize nut to coordinate with the external screw thread on punch holder, restriction drift body moves down, thereby complete the installation to the drift body, turn on nut and the drift body can be pulled down, easy accessibility, and the fixation of drift body, can not rock in installation cavity.
In punch device on above-mentioned a kind of punching die, offer several bar-shaped troughs on described punch holder.Limited block, along moving on bar-shaped trough, makes in the installation cavity on drift body insertion punch holder, and simultaneously, bar-shaped trough can limit the drift body and rotate in installation cavity, thereby prevents that it from rocking.
In punch device on above-mentioned a kind of punching die, still be provided with some limit ribs on described drift body, described limited block is arranged on the upper end of limit rib.Limit rib snaps in bar-shaped trough, the drift body is carried out circumferentially spacing, and limited block is resisted against the upper end of bar-shaped trough, and restriction drift body moves upward along installation cavity.
In punch device on above-mentioned a kind of punching die, offer one on described nut and dodge groove, described limited block can be connected to described dodging in groove.Dodge the existence of groove, can make nut to the drift main body to position-limiting action, further the drift body is fixed in installation cavity, due to the drift body when the punching press, the power that withstands shocks be punch holder, can't damage internal thread in nut and the external screw thread on punch holder.
In punch device on above-mentioned a kind of punching die, described limit rib has two, and radial distribution is on the outer surface of drift body.
Compared with prior art, the utlity model has following advantage:
1, this punch device utilizes nut to coordinate with the external screw thread on punch holder, and restriction drift body moves down, thereby completes the installation to the drift body, turning on nut can pull down the drift body, easy accessibility, and the fixation of drift body, can not rock in installation cavity.
2, be provided with one on the nut on this punch device and dodge groove, can make nut arrive position-limiting action to the drift main body, further the drift body is fixed in installation cavity, due to the drift body when the punching press, the power that withstands shocks be punch holder, can't damage internal thread in nut and the external screw thread on punch holder.
