Abstract
The invention discloses a regular hexagon drawing die. All relevant parameters of an inlet segment of the regular hexagon drawing die can be quantized. The regular hexagon drawing die comprises a drawing die body. The drawing die body is provided with a drawing forming hole which penetrates through the drawing die body. The drawing forming hole comprises the inlet segment and a sizing segment. The sizing segment comprises six flat-straight faces corresponding to six straight sides of a regular hexagon respectively. The distance between each pair of opposite flat-straight faces is a. The inlet segment comprises six leading-in bevels connected with the corresponding flat-straight faces of the sizing segment. Let the distance between the outer edge lines of each pair of opposite leading-in bevels be d1, then d1 is obtained through the formula showed in the specification, and 7.2<=k1<=7.5. The regular hexagon drawing die is used for drawing a circular pipe and a circular bar into a regular hexagon pipe and a regular hexagon bar respectively.
Description
Technical field
The present invention relates to and be drawn into pattern in Metal Forming technical field, refer more particularly to by circular pipe or bar drawing shaping be drawn into pattern (abbreviation drawing die).
Background technology
Drawing mould is the important fixture component of cold-drawn tubing and bar, be widely used in the reducing of tubing and bar or/and distortion production process in.For steel pipe, utilize drawing die to carry out cold drawn forming to steel pipe, there is the features such as stock utilization is high, energy consumption is low, properties of product are excellent, production efficiency is high, with low cost.In drawing mould, the tubing cross sectional shape shaping by its drawing is different, can be divided into circular drawing mould and special-shaped drawing mould; Have linerless core by its drawing process, can be divided into again empty sinking drawing die (being called for short empty sinking mould) and lining core drawing die (being called for short lining core), lining core drawing die is matched by external mold and internal mold and jointly completes cold-drawn.In drawing industry, the external mold of empty sinking drawing die or lining core drawing die is referred to as drawing die usually.
As everyone knows, if the length of the openings of sizes of drawing die and entrance arranges unreasonable, so tubing and the contact area between bar and mould change thereupon, there is unbalanced phenomena in the vertical and horizontal flowing of metal, thus it is second-rate to cause through the shaping hexagonal tube of its drawing or rod, be mainly manifested in its linearity poor (exist bend in various degree), wall unevenness is even, size is unstable and the defect such as surface irregularity, occurs steel pipe fracture and cracking phenomena in drawing process what is more.
At present; for the design standard that regular hexagon drawing die is also ununified; the length of its entrance and the setting of openings of sizes are all by rule of thumb; for pipe, the bar of each model; when designing, all through repeated multiple times test, improvement, the process tested again, just ideal drawing die to can be obtained; this not only extends the process-cycle of mould, also add production cost.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of relevant parameter of its entrance all quantifiable regular hexagon drawing die.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of regular hexagon drawing die, comprising: drawing die body, this drawing die body offers run through drawing die body be drawn into nibs, be drawn into nibs and comprise entrance and sizing section; Described sizing section comprises: six corresponding with orthohexagonal six straight flanges respectively flat faces, and the spacing between a pair flat face facing each other is a; Described entrance comprises: six importing inclined-planes be connected to the corresponding flat face of sizing section; If: the distance between the outside importing inclined-plane for a pair facing each other is along the line is d
1, then:
As a kind of preferred version, in described a kind of regular hexagon drawing die, the nibs that is drawn into of described drawing die body has outlet section in the arranged outside of sizing section, and this outlet section comprises six outwardly derivation inclined-planes be connected mutually to the corresponding flat face of positioning section respectively.
As a kind of preferred version, in described a kind of regular hexagon drawing die, between the derivation inclined-plane of described outlet section and the center line of described drawing die body, angle of inclination beta is between 30 ~ 45 degree.
As a kind of preferred version, in described a kind of regular hexagon drawing die, described outlet section accounts for and is wholely drawn into 8.17 ~ 9.17% of nibs, described sizing section accounts for and is wholely drawn into 27.6 ~ 29.6% of nibs, and described entrance accounts for and is wholely drawn into 61.5 ~ 63.5% of nibs.
As a kind of preferred version, in described a kind of regular hexagon drawing die, the profile of described welding bell body is cylindrical, its diameter d
2>=2a.
As a kind of preferred version, in described a kind of regular hexagon drawing die, six of described entrance import inclined-plane and are respectively arranged with circular arc chamfering.
As a kind of preferred version, in described a kind of regular hexagon drawing die, the radius of described circular arc chamfering is between 4.5 ~ 5.5 millimeters.
The invention has the beneficial effects as follows: drawing die of the present invention, the relevant parameter of its entrance can quantize, thus makes its designing and making all very simple, so just greatly reduces the process-cycle, saves production cost.In addition, by being arranged to cylindrical by welding bell body, and ensureing that its external diameter is greater than the twice of the spacing of a pair relative flat face of sizing section, ensure that the intensity of drawing die, making drawing quality obtain reliable guarantee.
