Abstract
The utility model discloses a processing device for a pipe-expansion screw blank. The processing device comprises a core mold (1) in which a central hole (2) is formed; an orifice at one end of the central hole (2) is an extrusion port (3) which is provided with a pipe-expansion hole (4) corresponding to an expansion pipe of a screw, wherein the shape of the extrusion port (3) corresponds to that of a pipe-expansion screw to be processed; and one end of the extrusion port (3) is provided with a punch (5). The device disclosed by the utility model can meet the processing requirements of the traditional three devices by cold heading one device, and a cold header can finish the processing of one pipe-expansion screw blank through reciprocating once under the action of mechanical transmission, therefore, the speed is extremely high, and 60 pipe-expansion screw blanks can be processed within one minute. The processing efficiency is greatly increased, the processing cost is reduced, and the advantages are created for mass production.
Description
Technical field
The utility model relates to a kind of processing unit (plant) of the bar screw blank that rises, and belongs to the extrusion die technical field.
Background technology
A kind of screw element is arranged, comprise head of screw and screw rod, its head of screw is the cross recess countersunk head, and being provided with length in the junction of head of screw and screw rod is the bar that rises of 0.8～1.5mm, and the diameter of the bar that rises is greater than screw diameter.Polished rod blank when the blank of this screw refers to undressed screw thread.The present processing method of the blank of this screw is first to carry out cold upset forming cross recess countersunk head at cold headers, and during cold upset forming cross recess countersunk head, screw portion first cold pier becomes diameter equal the to rise cylinder of shank diameter.Again with lathe at get on the bus out the cylindrical of threaded shank of cylinder, planar end surface chamfering, the rise face of cylinder of bar part of last grinding, the processing of whole blank need to adopt three kinds of equipment just can reach the dimensional requirement of product, therefore its process velocity is slow, process velocity be 7.5 minutes every, production efficiency is low.Do not satisfy the requirement of batch production, urgent need will be enhanced productivity.
Summary of the invention
The purpose of this utility model is, a kind of processing unit (plant) of the bar screw blank that rises is provided.With the solution low problem of bar screw blank working (machining) efficiency that rises, enhance productivity, satisfy the requirement of batch production.
The technical solution of the utility model:
A kind of processing unit (plant) of the bar screw blank that rises, comprise core, core is provided with centre bore, and the aperture of centre bore one end is extrusion mouth, the shape of extrusion mouth is corresponding with the shape of the bar screw that rises to be processed to be provided with and the screw corresponding bar hole of rising of shank diameter of rising, and an end of extrusion mouth is provided with drift.
In the processing unit (plant) of the aforementioned bar screw blank that rises, be provided with push rod in the centre bore of described core.
In the processing unit (plant) of the aforementioned bar screw blank that rises, described core is provided with die sleeve outward; Die sleeve is provided with locating slot.
In the processing unit (plant) of the aforementioned bar screw blank that rises, described core is the carbide alloy product.
In the processing unit (plant) of the aforementioned bar screw blank that rises, the described bar hole of rising is polished bore, its roughness≤0.8 μ m.
Compared with prior art, prior art is to adopt cold pier, Vehicle Processing and grinding three first operations to finish the processing of the bar screw blank that rises, needs of every processing 7.5 minutes.Device of the present utility model only needs a kind of equipment of cold pier can satisfy the processing request of existing three kinds of equipment, cold headers adopt machine driving to make a round trip, can finish the processing of the bar screw blank that rises, speed is exceedingly fast, and finishes the processing of 60 bar screw blanks that rise in one minute.Improved greatly working (machining) efficiency, reduced processing cost, for advantage has been created in batch production.
