Description

Technical Field

[0001] This application relates to the field of wire processing technology, specifically a rotating eye mold for wire processing. Background Technology

[0002] In the field of wire processing, especially in the drawing or extrusion of metal wires, the die (also known as the sizing die) is a core process equipment, and its performance directly affects the dimensional accuracy, surface quality and production efficiency of the wire.

[0003] Existing traditional eye molds typically employ a fixed mold core structure. The wire is drawn to a fixed diameter through the mold hole under unidirectional traction force. This fixed mold core structure causes uneven wear distribution in the contact area due to continuous unidirectional friction between the wire and the inner wall of the mold hole during unidirectional traction. This leads to rapid deterioration of the geometric accuracy of the mold hole, resulting in scratches on the wire surface and a decrease in diameter stability. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a rotating eye mold for wire processing to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a rotating eye mold for wire processing, including an eye mold box, one end of which is provided with a wire inlet, and the other end of which is provided with a wire outlet. A drawing box is fixedly installed inside the eye mold box, and a rotating cylinder is rotatably connected to the inner surface of the drawing box. A rotating eye mold is detachably installed inside the rotating cylinder through a limiting mechanism. A gear drive mechanism for driving the rotating eye mold to rotate is provided on the eye mold box.

[0006] Preferably, the limiting mechanism includes a slot formed in the inner wall of the rotating cylinder, and the outer surface of the rotating eye mold is fixedly connected with a longitudinal limiting rod and a transverse limiting rod, and the outer surfaces of the longitudinal limiting rod and the transverse limiting rod are slidably inserted into the inner side of the slot. The limiting mechanism can keep the rotating eye mold in a relatively stable state in the rotating cylinder, thereby making the wire run smoothly during the sizing and thinning process of the rotating eye mold.

[0007] Preferably, a rubber pad is embedded in the lateral limiting rod, and a limiting plug is movably inserted into one end of the lateral limiting rod near the inlet.

[0008] Preferably, the gear drive mechanism includes a drive box fixedly connected to the outer surface of the eye mold box. A motor is fixedly installed on the outer surface of the drive box, and a drive shaft is fixedly connected to the output end of the motor. The gear drive mechanism can drive the rotating drum to rotate, thereby causing the rotating eye mold to rotate synchronously. This can improve the roundness of the drawn wire, and the wear of the mold is more uniform during the process, thus extending the service life of the mold.

[0009] Preferably, a first gear is fixedly sleeved on the outer surface of the drive shaft, a rotating shaft is fixedly connected to the inner side of the pull box, a second gear is rotatably connected to the outer surface of the rotating shaft, and the outer surface of the second gear meshes with the outer surface of the first gear.

[0010] Preferably, a third gear is fixedly sleeved on the outer surface of the rotating cylinder, and the outer surface of the third gear meshes with the outer surface of the second gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This rotating die for wire processing uses a gear-driven mechanism to achieve active rotation of the die core, which causes the contact area between the inner wall of the die hole and the wire to change dynamically in the circumferential direction. This avoids the problem of localized unidirectional wear of traditional fixed die cores. The rotating cylinder drives the rotating die to rotate stably, which can significantly homogenize the wear distribution of the die hole, maintain the geometric accuracy of the die hole, thereby reducing scratches on the wire surface, improving the roundness of the drawn wire, and extending the service life of the die.

[0012] 2. This rotating eye mold for wire processing, through the insertion design of longitudinal and transverse limiting rods in the slot, combined with the elastic fit of the rubber pad and the mechanical constraint of the limiting rods, ensures that the rotating eye mold maintains accurate angular positioning under high-speed rotation conditions, resists the core displacement caused by centrifugal force, and ensures the accuracy of wire processing. In addition, the detachable design of the limiting rods simplifies the core replacement process. The rotating eye mold can be quickly disassembled and assembled simply by pulling out the rods, which greatly improves maintenance efficiency. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-6 A rotating eyepiece for wire processing includes an eyepiece box 1, with an inlet 2 at one end of the eyepiece box 1 and an outlet 3 at the end of the eyepiece box 1 away from the inlet 2. A drawing box 4 is fixedly installed inside the eyepiece box 1, and a rotating cylinder 5 is rotatably connected to the inner surface of the drawing box 4. A rotating eyepiece 6 is detachably installed inside the rotating cylinder 5 through a limiting mechanism. A gear drive mechanism for driving the rotating eyepiece 6 to rotate is provided on the eyepiece box 1.

[0017] Through the above technical solution, the eye mold box 1 serves as an overall support carrier. The inlet 2 and outlet 3 at both ends of the box form a wire processing channel. The wire enters the rotary cylinder 5 through the inlet 2 and is sized and drawn in the die hole of the rotating eye mold 6. After the drawing process, the wire is pulled out through the outlet 3. The rotary cylinder 5 can be driven by a gear drive mechanism to drive the rotating eye mold 6 to rotate actively, so that the contact area between the inner wall of the die hole and the wire changes dynamically. This significantly improves the problem of local wear of traditional fixed die cores and enhances the surface quality of the wire and the service life of the die.

[0018] Specifically, the limiting mechanism includes a slot 7 opened in the inner wall of the rotating cylinder 5, and a longitudinal limiting rod 8 and a transverse limiting rod 9 are fixedly connected to the outer surface of the rotating eye mold 6, and the outer surfaces of the longitudinal limiting rod 8 and the transverse limiting rod 9 are slidably inserted into the inner side of the slot 7.

[0019] Through the above technical solution, the slot 7 opened on the inner wall of the rotary cylinder 5 forms a sliding insertion fit with the longitudinal limiting rod 8 and the transverse limiting rod 9 fixed on the outer surface of the rotating eye mold 6. The longitudinal limiting rod 8 and the transverse limiting rod 9 restrict its circumferential rotational freedom. The two work together to ensure that the rotating eye mold 6 maintains a fixed angular position in the rotary cylinder 5. This design enables the rotating eye mold 6 to rotate synchronously with the rotary cylinder 5 to achieve uniform wear, and also avoids the core displacement caused by centrifugal force or wire traction force, thus ensuring the stability of wire processing accuracy.

[0020] Specifically, a rubber pad 10 is embedded in the transverse limiting rod 9, and a limiting plug 11 is movably inserted into one end of the transverse limiting rod 9 near the inlet 2.

[0021] Through the above technical solution, the limiting rod 11 is inserted into the broken end of the transverse limiting rod 9. The rubber pad 10 embedded in the transverse limiting rod 9 (utilizing its elastic deformation effect) can maintain the stability of the insertion of the limiting rod 11. Through the mechanical blocking effect, the transverse limiting rod 9 is prevented from coming out of the slot 7 under the action of traction force or centrifugal force, thereby enhancing the structural reliability and improving the impact resistance and positioning stability of the rotating eye mold 6 under high-speed rotation conditions during the cooperative process.

[0022] Specifically, the gear drive mechanism includes a drive box 12 fixedly connected to the outer surface of the eye mold box 1, a motor 13 fixedly mounted on the outer surface of the drive box 12, and a drive shaft 14 fixedly connected to the output end of the motor 13.

[0023] Through the above technical solution, the motor 13 mounted on the outer surface of the drive box 12 outputs torque through the drive shaft 14, and the fixedly sleeved first gear 15 transmits the rotational power to the second gear 17, thereby using the rotation of the first gear 15 to drive the second gear 17 to rotate synchronously in the opposite direction.

[0024] Specifically, a first gear 15 is fixedly sleeved on the outer surface of the drive shaft 14, a rotating shaft 16 is fixedly connected to the inner side of the pull box 4, a second gear 17 is rotatably connected to the outer surface of the rotating shaft 16, and the outer surface of the second gear 17 meshes with the outer surface of the first gear 15.

[0025] Through the above technical solution, the first gear 15 fixed on the outer surface of the drive shaft 14 and the second gear 17 rotatably connected on the rotating shaft 16 form a meshing transmission. The rotating shaft 16 serves as the rotation fulcrum of the second gear 17, ensuring the smoothness of gear meshing. During this process, the second gear 17 will transmit the power of the motor 13 to the third gear 18 as it rotates along the rotating shaft 16.

[0026] Specifically, a third gear 18 is fixedly sleeved on the outer surface of the rotating cylinder 5, and the outer surface of the third gear 18 meshes with the outer surface of the second gear 17.

[0027] Through the above technical solution, the third gear 18 fixedly sleeved on the outer surface of the rotating cylinder 5 meshes with the second gear 17, and the rotational power of the transmission system is directly applied to the rotating cylinder 5. That is, after the third gear 18 is driven by the meshing of the second gear 17, it will rotate synchronously in the opposite direction, and finally drive the rotating cylinder 5 to rotate. This design achieves the stability of power transmission through multi-stage gear transmission, so that the contact area between the inner wall of the rotating eye die 6 and the wire changes periodically, which significantly extends the service life of the die and improves the roundness of the wire drawing.

[0028] Working Process and Principle: During use, the wire enters the drawing box 4 through the inlet 2 at one end of the eyepiece box 1, passes through the rotating eyepiece 6 hole fixed by the limiting mechanism inside the rotating cylinder 5, and is drawn and sized under the action of traction force before being output from the outlet 3. During this process, the gear drive mechanism is activated: the motor 13 outside the drive box 12 drives the first gear 15 to rotate through the drive shaft 14, and the second gear 17 meshing with it rotates stably around the rotating shaft 16. The second gear 17 transmits power to the third gear 18 fixed to the rotating cylinder 5, driving the rotating cylinder 5 to drive the rotating eyepiece 6 to achieve active rotation. The longitudinal limiting rod 8 and the transverse limiting rod 9 set on the outer surface of the rotating eyepiece 6 slide and engage with the slot 7 on the inner wall of the rotating cylinder 5. Under the elastic cooperation of the rubber pad 10 and the mechanical blocking action of the limiting rod 11, the rotating eyepiece 6 is ensured to rotate at high speed. Maintaining precise angular positioning allows the wire to undergo dynamic circumferential changes in the contact area between the inner wall of the die hole and the wire during the sizing and thinning process of the rotating eye mold 6. This effectively resists the core displacement caused by centrifugal force (preventing the rotating eye mold 6 from moving towards the wire outlet 3). Through the power transmission of the multi-stage gear transmission system and the dual constraints of the limiting mechanism, the rotating eye mold 6 uniformly wears the die hole during continuous rotation, significantly improving the local wear problem of traditional fixed die cores. At the same time, the dynamic contact of the die hole suppresses the spiral defects of the wire, ultimately obtaining finished wires with excellent surface quality and high diameter stability, and greatly extending the service life of the mold. After the limiting rod 11 is pulled out from the end of the transverse limiting rod 9, the rotating eye mold 6 can be pulled out from the rotating cylinder 5 (during this process, the transverse limiting rod 9 and the longitudinal limiting rod 8 will slide synchronously along the slot 7) so that the rotating eye mold 6 can be removed and replaced.
