[0002] The chamfered conical surface steel wire is mainly used for the second ring of the piston ring of the engine and mainly plays the role of sealing and oil control. The forming methods of the chamfered conical surface steel wire mainly include three kinds: the first kind is grinding processing, that is, the chamfered conical surface is formed by grinding the steel wire through a high-precision grinding machine and the cooperation of a suitable grinding wheel; the second kind is stamping forming, that is, the steel wire is stamped through a stamping machine and a stamping die, and the steel wire is formed into a chamfered conical surface through the up-down movement of the die to apply pressure to the steel wire; and the third kind is drawing processing, that is, the steel wire sequentially passes through a plurality of stages of dies with specific shapes which are arranged in front and back during the drawing process, and the shape of the die can make the steel wire gradually form a chamfered conical surface. It is gradually found in the use process that the above-mentioned three kinds of forming methods each have the following deficiencies: the grinding processing requires a high-precision grinding machine, and the requirements for the equipment and the operation level of the personnel are relatively high, so the cost of the grinding forming is high and the production efficiency is low. The stamping forming uses a stamping die, and the surface quality and precision of the steel wire after stamping are relatively poor, so subsequent finishing is required to improve the surface quality and dimensional precision of the steel wire, so the production cost of the stamping forming is high and the efficiency is low. The drawing processing can complete part of the forming work while drawing the steel wire, and the production efficiency is relatively high, but the requirements for the precision of the die and the plasticity of the steel wire material are relatively high.

[0016] The utility model discloses will make further description below with the drawings:
[0017] As Figure 1As shown, the device for one-time forming of chamfered conical steel wire according to this utility model includes an upper flat roller 1 and a lower flat roller 3 arranged vertically opposite each other and capable of vertical translation (on the one hand, after the positions of the left chamfering roller 2 and the right conical roller 4 are fixed, it is used to tighten the upper and lower planes of the left chamfering roller 2 and the right conical roller 4; on the other hand, the lower surface of the chamfered conical steel wire 5 is formed and controlled by the extrusion deformation of the steel wire by the upper top surface of the lower flat roller 3), and a left chamfering roller 2 and a right conical roller 4 arranged vertically opposite each other and capable of left and right translation (by means of the sliding friction between the left chamfering roller 2 and the right conical roller 4 and the steel wire during the rolling process, the steel wire moves forward while longitudinally passing through the opposite rollers). The roll extrusion forming die allows for the efficient and precise one-time forming of chamfered conical steel wire. It effectively controls the chamfer dimensions, cone dimensions, and surface finish, offering advantages such as accurate dimensions, high precision, good surface quality, high efficiency, and low cost. Furthermore, the low sliding friction significantly reduces the requirements for the steel wire's plasticity and toughness, extending the roller's lifespan. This results in low cost, simple equipment, and easy operation. When forming chamfered conical steel wire with the same chamfer, cone, and height but varying width, only the left chamfer needs to be adjusted. The distance between the left and right chamfered rollers and the right conical roller is sufficient, meaning that the same set of rollers can be used to form chamfered conical steel wires with varying widths, offering advantages such as wide applicability, strong versatility, low cost, and high efficiency. The upper and lower planes of the roller surfaces of the left chamfered roller 2 and the right conical roller 4 are clamped between the upper flat roller 1 and the lower flat roller 3 (after the positions of the left chamfered roller 2 and the right conical roller 4 are fixed, the upper and lower planes are tightened by the upper flat roller 1 and the lower flat roller 3). A chamfered circumferential groove 2-1 with a rectangular cross-section having a chamfer at the upper left corner and extending around the circumference is cut from the lower corner of the left chamfered roller 2. A chamfered circumferential groove 2-1 is cut from the lower corner of the right conical roller 4. A right-angled trapezoid with a right-side sloping waist and a right conical circumferential groove 4-1 extending in a circle, a left chamfered circumferential groove 2-1, a right conical circumferential groove 4-1 and a lower flat roller 3 together form a roller extrusion forming mold for chamfered conical steel wire 5. (The steel wire is driven to move forward and longitudinally pass through the roller extrusion forming mold by means of the sliding friction between the left chamfered roller and the right conical roller during the roller extrusion process. During this process, the steel wire is extruded and formed by roller extrusion. This can achieve one-time forming of chamfered conical steel wire efficiently and accurately, and effectively control the chamfer size, conical size and surface finish of chamfered conical steel wire.)
[0018] The upper and lower heights of the left chamfer circumferential groove 2-1 and the right conical circumferential groove 4-1 are equal to the thickness of the chamfer conical steel wire 5 to be formed; the chamfer of the left chamfer circumferential groove 2-1 is matched with the chamfer of the chamfer conical steel wire 5 to be formed; and the conical surface of the right conical circumferential groove 4-1 is matched with the conical surface of the chamfer conical steel wire 5 to be formed (the cross section of the chamfer conical steel wire 5 obtained by roll extrusion forming is ensured to reach the preset thickness, chamfer and conical surface, and accurate forming and high-precision forming are realized).
[0019] The left chamfer roller 2 and the right conical roller 4 are arranged in a vertical coaxial line (centering, and the balance and symmetry of force application are easily ensured).
[0020] The upper and lower planes of the left chamfer roller 2 and the right conical roller 4 are parallel to each other and have smooth surfaces (translation is facilitated when the distance is adjusted, and the balance of force application and force bearing is facilitated when clamping is performed).
[0021] The left chamfer roller 2 and the right conical roller 4 are made of hard alloy (sufficient hardness is ensured for roll forming).
[0022] The specific use of the utility model is as follows:
[0023] Firstly, the left chamfer roller 2 and the right conical roller 4 are selected and preassembled according to the thickness, chamfer and conical surface of the chamfer conical steel wire 5 to be formed; then, the horizontal distance between the left chamfer roller 2 and the right conical roller 4 is adjusted according to the width of the chamfer conical steel wire 5 to be formed, and the left chamfer roller 2 and the right conical roller 4 are fixed in position in a symmetrical distribution about the axis of the upper roller 1 and the lower roller 3; then, the upper roller 1 is moved downward, and the lower roller 3 is moved upward to clamp the upper and lower planes of the left chamfer roller 2 and the right conical roller 4; subsequently, the steel wire is driven to move forward and longitudinally through the roll extrusion forming mold box in the process of roll forming of the left chamfer roller 2 and the right conical roller 4, and the steel wire is roll extrusion formed in this process, so that the one-time forming of the chamfer conical steel wire is efficiently and accurately realized, and the chamfer size, conical surface size and surface smoothness of the chamfer conical steel wire are effectively controlled, and the utility model has the advantages of accurate forming size, high precision, good surface quality, high efficiency and low cost.
[0024] When the chamfered and tapered steel wire with the same chamfer height and taper height but different width is needed, the left and right distance between the left chamfer roller 2 and the right taper roller 4 is adjusted only, that is, the same set of rollers can be used to form the chamfered and tapered steel wire with different width, which has the advantages of wide application range, strong versatility, low cost and high efficiency.
[0025] When the chamfered and tapered steel wire with different chamfer height and taper height is needed, the left chamfer roller 2 and the right taper roller 4 matched with the chamfer and taper of the required chamfered and tapered steel wire 5 are only exchanged to realize the universal production.
