Abstract
The utility model discloses a cold heading die for an automatic heading machine. The cold heading die for the automatic heading machine comprises a shear bottom, a main die, shears, a primary trimming die and a secondary trimming die, wherein the main die comprises a die shell, a die core, an inner die and a sleeve sheet, and the die core is fixedly arranged in the die shell. The inner die is arranged on the front section in the die shell, an inner die hole is further formed in the inner die, and protruding bars are further arranged on the inner wall of the inner die hole in the axial direction. The sleeve sheet is arranged at the front end of the inner die, a sleeve sheet hole communicated with the inner die hole is formed in the sleeve sheet, and the sleeve sheet is fixed to the die shell through a lantern ring. N grooves of a product can be formed through secondary cold heading by using the high-speed automatic heading machine in a continuous stepping mode, secondary machining forming of thread molding does not need to be carried out, and therefore the phenomena that scrap iron blocks thread plates, the thread plates are large in loss, and the quality is unstable will not be caused.
Description
Technical field
The utility model relates to the screw manufacturing equipment, more particularly, relates to the automatic heading machine cold upsetting die of car of a kind of screw.
Background technology
Usually, a N commonly used U-shaped or vee-cut part are to be processed without the groove blank by cold-heading, then are twisted into N U-shaped or vee-cut shape by dental lamina.But the shortcoming of this processing is:
When 1, dental lamina edge column is rubbed N U-shaped or vee-cut with the hands, can not along triangle section is all-round, be uniformly distributed accurately, because of product blanking no-fix, groove arbitrarily distributes at circumferencial direction;
2, groove is by the extrusion modling of dental lamina column, and the column discontinuity, cause dental lamina to burst apart, and the dental lamina loss is large;
3, reach and descend in shape fluctuation ratio larger such as the actual product groove dimensions, product quality is difficult to effectively be guaranteed.
The utility model content
The purpose of this utility model aims to provide the automatic heading machine cold upsetting die of car of a kind of screw, solves measurement inaccuracy of the prior art, deviation is arranged.
The automatic heading machine cold upsetting die of car of this screw, be located on the automatic heading machine of screw, comprise hard-wiredly cut the end, be installed on the main mould of cutting the end one side, with cut the scissors that the end and main mould be used in conjunction with and a punch die, the secondary punch die that closes respectively use with main grinding-in; Described main mould comprises formwork, core rod, internal mold and nest plate, and core rod is fixedly arranged in formwork, and internal mold is located at leading portion in formwork, also is provided with interior nib in internal mold, and interior nib inwall also is provided with raised line on axially; Nest plate is located at the internal mold front end, is provided with the cover film perforation be connected with interior nib in nest plate, and fixes by the collar and formwork.
The radial section of described interior nib is triangle.
The radial section of described cover film perforation is circular.
The quantity of described raised line is N that is evenly arranged.
The radial section of described raised line is U-shaped or V-arrangement.
Described cold upsetting die of car also comprises baffle plate, with the baffle plate front end, is oppositely arranged.
The automatic heading machine of screw of the present utility model comprises and cuts the end, main mould, scissors, punch die, secondary punch die with cold upsetting die of car, and main mould comprises formwork, core rod, internal mold and nest plate, and core rod is fixedly arranged in formwork; Internal mold is located at the leading portion in core rod hole, and is shorter in length than core rod, also is provided with interior nib in internal mold, and interior nib inwall also is provided with raised line on axially, and internal mold is located in the core rod circular hole; Nest plate is located at the internal mold front end, and fixes by the collar and formwork.Can utilize High-Speed Automatic heading machine, adopt the mode advance continuously level, a product N groove, by the secondary cold-heading molding, need not be carried out to the moulding of threading secondary operations, thereby can not produce, quality unsettled phenomenon large such as iron filings obstruction dental lamina, dental lamina loss; And can, after the board debugging is normal, carries out mechanical automation and produce continuously; And making produced product, dimensional tolerance is accurately controlled very little scope, can not produce larger fluctuation, effectively guarantees the quality of product.
The accompanying drawing explanation
In the utility model, identical Reference numeral means identical feature all the time, wherein:
