Abstract

The utility model provides a three-roller type drawing die device used to draw the irregular metal wire whose cross-section shape is triangle or is provided with triangle tendency. The three-roller type drawing die device is composed of a machine frame, a front shroud, a radical adjusting screw, an adjusting screw, a scale indication disc, a roller, a roller box, a roller seat, an antithrust bearing, a back shroud and a rail. The main technique characteristic is that a group of the rollers can be used to draw out numerous of metal wires whose size is different, but the cross-section geometric-form is similar triangle and the hole size is adjusted from a certain size to zero and the three-roller type drawing die device is convenient to adjust during operation with few roller spare parts and is convenient to popularize and use.

Description

Three-roller type drawing die device

The utility model belongs to the drawing mould equipment in the Steel Wire Products Industry, is applicable to that the drawing shape of cross section is triangle or the special-shaped wire product with triangle trend.

Before the utility model, domestic and international drawing triangle or have the employed rolling drawing die device of triangle trend cross section special-shaped silk product and be generally dual roll type and three-roller type two big classes, because metal deformation is compared with metal deformation in two roll pass and is had a series of superiority in three roll pass, therefore three-roller type rolling drawing die device is produced at special-shaped silk and has been obtained using widely, yet there is certain defective in existing three-roller type rolling drawing die device, it is the size property adjusted not of pass, that is to say, one group of roller can only be formed a closed type, therefore when the drawing shape is similar but will change roller during the triangle section silk that dimensions is different, the operation adjustment waits the work more complicated, required standby redundancy and roller quantity are many, processing and manufacturing acquires a certain degree of difficulty, should not adopt, but therefore be necessary to design a kind of in same group of roller drawing go out countless versions dimensions difference but the similar special-shaped three-roller type rolling drawing die device wiry of triangle of cross-sectional geometry.

The purpose of this utility model provides a kind of three-roller type rolling drawing die device, the special-shaped three-roller type rolling drawing die device wiry in drawing triangular-section particularly, it is to the relative position placed between the existing three-roller type rolling drawing die device middle roller and adjust version and improve, thereby makes and can produce similar but the various triangle sections abnormal shape wires that dimensions is different of shape with one group of roller.

The utility model produces in the inspiration that is subjected to two similar triangles figures that vary in size that nest together, i.e. the triangle that the feasible sealing triangle pass of being made up of three rollers of relative position of adjustment distortion mould roller can be changed into another size continuously by the triangle of a size is realized.

Design of the present utility model is that this will realize: three the distortion rollers (6) in the described three-roller type rolling drawing die device are respectively lower rolls, upper left roller and upper right roller.The axial direction of lower roll is fixed, and its axis direction is a horizontal direction, and right roll axis is from the horizontal by 120 °, and the axis of left roller is from the horizontal by 60 °, and three rollers can be done a small amount of conformability adjustment in radial direction by adjusting screw.Different with existing three-roller type rolling drawing die device is, the arrangement of roller is shape in the shape of a spiral, and promptly the roll surface axial symmetry line of three rollers does not intersect at same point; Upper right roller can whole along continuous straight runs adjustment, and upper left roller can wholely be adjusted along its axis direction.

The utility model is compared with existing three-roller type rolling drawing die device, and the pass size adjusting is convenient, and the standby redundancy of roller is few, and the pass size dimension can adjust to zero always.But go out more complicated special-shaped silk if on three rollers, suitably grind upper curve pass mould and combine also drawing.

Description of drawings:

Fig. 1: the outward appearance of three-roller type rolling drawing die device is faced the garden, among the figure: 1, Rack Body; 2, front shroud; 3, radially adjust screw; 4, adjust screw rod; 5, scale indicating dial; 6, roller.

Fig. 2: throw off the front view of these three roller rolling drawing die devices behind the front shroud, among the figure: 7, left roller box; 8, right roller box; 9, roller seat; 10, thrust bearing; 11, back shroud; 12, guide rail.

The utility model embodiment in conjunction with the accompanying drawings 1, accompanying drawing 2 is described as follows: three distortion rollers (6) all are placed on roller seat (9) and go up and fix, one of them roller seat (lower roller base) is put into out in the groove on Rack Body (1), two other (left roller seat and right roller seat) is placed on respectively in left roller box (7) and the right roller box (8), right roller box (8) is placed in the horizontal direction chute of being made up of the medial surface and the guide rail (12) of Rack Body (1), the medial surface of Rack Body (1) is close in the bottom surface of left side roller box (7), its lower end is put into out in the chute on Rack Body, the central symmetry axes of chute is from the horizontal by 60 °, guide rail (12) is fixed on the back shroud (11), three rollers are after its rigging position separately installs, three rollers shape are in the shape of a spiral arranged, i.e. line of symmetry in the roll surface of three rollers and do not intersect at same point, by adjusting screw rod (4), left side roller box (7) can carry out integral body slip adjustment in direction and horizontal direction from the horizontal by 60 ° respectively with right roller box (8), form the continuous closed type of a series of sizes, the adjustment amount of pass size can be read by scale indicating dial (5), in addition, three rollers its also can do a small amount of the cooperation and adjust in the radial direction separately by radially adjusting screw (3).When being adjusted into another similarly triangle pass by a triangle pass, be that the difference of two triangle corresponding sides can be finished adjustment as long as make reading on the scale indicating dial (5).So also just realized using same group of roller to get final product the special-shaped wire in triangular-section that drawing goes out the countless versions specification.

Claims

1, three-roller type rolling drawing die device, the special-shaped three-roller type rolling drawing die device wiry of drawing triangle section particularly, it comprises Rack Body (1), front shroud (2), radially adjust screw (3), adjust screw rod (4), scale indicating dial (5), the left roller box of roller (6) (7), right roller box (8), roller seat (9), thrust bearing (10), back shroud (11), guide rail (12), it is characterized in that: distortion mould roller (6) is placed and is fixed on the roller seat (9), wherein lower roller base is placed in the groove on the Rack Body (1), a left side, right roller seat is placed on left roller box (7) respectively, in the right roller box (8), and left roller box (7), right roller box (8) respectively can be by adjusting screw rod (4) thereby is adjusted the position that changes roller (6), in addition, in the upwards also suitably adjustment of available radial adjustment screw (3) do of the footpath of roller (6).
