Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, and in particular to a processing equipment for powder metallurgy high alloy high-speed steel wire. Background Technology

[0002] With the development of high-end manufacturing industries (such as aerospace and precision tool manufacturing), the forming and demolding process of high alloy high-speed steel wire requires precise forming and stable demolding of high-hardness and high-brittle materials, which requires the use of processing equipment.

[0003] In practical use, similar processing equipment still has many defects. For example, traditional processing equipment usually relies on manual or complex mechanical structures for demolding, which results in low operating efficiency. During the demolding process, the wire is prone to scratches and deformation due to uneven force or collision. At the same time, the impact force when the forming box of traditional processing equipment descends is directly transmitted to the equipment frame. Long-term operation will lead to increased vibration, loosening of parts, and even affect the forming accuracy. Therefore, it is necessary to design a processing equipment for powder metallurgy high alloy high-speed steel wire. Summary of the Invention

[0004] The problem to be solved by this utility model is to provide a processing equipment for powder metallurgy high alloy high-speed steel wire, which addresses the shortcomings of the prior art.

[0005] To solve the above problems, the present invention adopts the following solution: a processing equipment for powder metallurgy high-alloy high-speed steel wire, comprising a processing component, wherein the processing component includes an electric lead screw, a slide rail is provided on one side of the electric lead screw, a forming box is slidably installed inside the electric lead screw, and the side of the forming box away from the electric lead screw is slidably installed inside the slide rail, and further comprising:

[0006] A clamping assembly, the clamping assembly including a worm gear slidably installed inside the molding box, and a clamping ring provided on one side of the worm gear via a force-bearing gear;

[0007] A buffer assembly includes a buffer cylinder fixedly connected inside the molding box, a connecting rod slidably installed inside the buffer cylinder, and the bottom of the connecting rod fixedly connected to the top of the base plate.

[0008] As a further improvement to the above solution, guide grooves are provided on both sides of the inside of the molding box, and a molding groove is provided at the center of the inside of the molding box.

[0009] Through the above technical solution, the guide groove provides a sliding track for the clamping ring, ensuring the stability of its opening and closing movement direction. The forming groove, as a mold for wire forming, is designed in the center to ensure the symmetry of wire forming and improve product precision.

[0010] As a further improvement to the above solution, a pin is fixedly connected to the center of the top of the base plate, the pin is slidably installed inside the molding groove, a connecting plate is fixedly connected to the outer surface of the base plate, and a worm gear is fixedly connected to the top of the connecting plate.

[0011] Through the above technical solution, the ejector pin directly contacts the wire, and the wire is ejected by the downward movement of the molding box, achieving efficient demolding. The connecting plate rigidly connects the worm gear and the base plate to ensure the stability of power transmission.

[0012] As a further improvement to the above solution, a worm gear is fixedly connected to the top of the molding box, one side of which meshes with a worm, and a force-bearing gear is rotatably mounted on the outer surface of the molding box, one side of which meshes with the worm gear.

[0013] Through the above technical solution, the meshing of the worm gear and the worm transforms linear motion into rotational motion, driving the force-bearing gear to rotate. The dual-gear transmission system amplifies the power output and increases the opening and closing force of the clamping ring.

[0014] As a further improvement to the above solution, a clamping ring is slidably installed inside the guide groove, and a force-bearing rack is fixedly connected to both sides of the outer surface of the clamping ring, and the force-bearing rack meshes with the force-bearing gear.

[0015] Through the above technical solution, the meshing of the rack and gear drives the clamping ring to slide along the guide groove, achieving symmetrical opening and closing. The cooperation between the rack and gear ensures that the clamping force is evenly distributed.

[0016] As a further improvement to the above solution, a first buffer spring is fixedly connected to the inner wall of the buffer cylinder, a push plate is fixedly connected to the bottom of the first buffer spring, and a connecting rod is fixedly connected to the bottom of the push plate.

[0017] Through the above technical solution, the first buffer spring contracts when the forming box descends, absorbing the impact energy, and the push plate transmits the spring force to the connecting rod, thus reducing equipment vibration.

[0018] As a further improvement to the above solution, a second buffer spring is fixedly connected to the bottom of the inner wall of the buffer cylinder, the top of the second buffer spring is fixedly connected to the bottom of the push plate, and the second buffer spring is sleeved on the outer surface of the connecting rod.

[0019] Through the above technical solution, the second buffer spring provides secondary buffering after the first spring contracts, forming a graded damping system. The design of being sleeved on the connecting rod avoids uneven loading of the spring.

[0020] The technical effects of this utility model are as follows: This utility model ensures that the forming box slides accurately in a fixed direction through the cooperation of the electric screw and the slide rail, avoiding deviation and providing a reliable foundation for subsequent processing. The contact and ejection action of the ejector pin efficiently separates the formed wire from the forming groove, reducing manual intervention and improving demolding efficiency. The elastic contraction of the first buffer spring effectively absorbs the instantaneous impact force when the forming box descends, reducing equipment vibration, extending the life of mechanical parts, and ensuring the stability of the forming box movement. Through the coordinated drive of the electric screw and the slide rail, combined with the demolding action of the ejector pin and the energy absorption of the first buffer spring in the buffer cylinder, the smooth descent of the forming box and impact buffering are achieved, thereby significantly improving the stability of equipment movement and the demolding efficiency of the wire.

[0021] This invention converts linear motion into rotational motion through the meshing transmission of a worm gear and a worm wheel. The driving gear moves the clamping ring along the guide groove, achieving symmetrical opening and closing of the clamping ring. This ensures uniform force on the wire and avoids localized damage. The clamping ring provides stable support at the moment the ejector pin pushes the wire out, preventing the wire from falling off due to gravity or external force, thus ensuring processing continuity and safety. The secondary buffering effect of the second buffer spring, together with the first buffer spring, forms a graded buffering system, further absorbing residual impact force, reducing stress concentration in the equipment frame, and extending the equipment's service life. The rigid connection of the connecting rod ensures that the buffering force is evenly transmitted to the entire equipment, avoiding localized structural damage and improving equipment reliability.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0029] Please combine Figure 1-5 This embodiment of a powder metallurgy high-alloy high-speed steel wire processing equipment includes a processing component 1. The processing component 1 includes an electric lead screw 101, a slide rail 102 is provided on one side of the electric lead screw 101, a forming box 103 is slidably installed inside the electric lead screw 101, and the side of the forming box 103 away from the electric lead screw 101 is slidably installed inside the slide rail 102. It also includes:

[0030] The clamping assembly 2 includes a worm gear 204 that is slidably installed inside the molding box 103, and a clamping ring 208 is provided on one side of the worm gear 204 via a force-bearing gear 206.

[0031] The buffer assembly 3 includes a buffer cylinder 301 fixedly connected inside the molding box 103. A connecting rod 304 is slidably installed inside the buffer cylinder 301, and the bottom of the connecting rod 304 is fixedly connected to the top of the base plate 201.

[0032] The molding box 103 has guide grooves 104 on both sides inside, and a molding groove 105 in the center inside.

[0033] A ejector pin 202 is fixedly connected to the center of the top of the base plate 201. The ejector pin 202 is slidably installed inside the molding groove 105. A connecting plate 203 is fixedly connected to the outer surface of the base plate 201. A worm gear 204 is fixedly connected to the top of the connecting plate 203.

[0034] A worm gear 205 is fixedly connected to the top of the molding box 103. One side of the worm gear 205 meshes with the worm 204. A force-bearing gear 206 is rotatably mounted on the outer surface of the molding box 103. One side of the force-bearing gear 206 meshes with the worm gear 205.

[0035] A clamping ring 208 is slidably installed inside the guide groove 104. A force-bearing rack 207 is fixedly connected to both sides of the outer surface of the clamping ring 208. The force-bearing rack 207 meshes with the force-bearing gear 206.

[0036] As the molding box 103 descends, the worm 204 moves synchronously with the connecting plate 203. Since the worm wheel 205 meshes with the worm 204, the linear motion of the worm 204 is converted into the rotational motion of the worm wheel 205. The worm wheel 205 further drives the force-bearing gear 206 meshing with it to rotate, forming a power transmission chain. The force-bearing gear 206 meshes with the force-bearing rack 207 on the outside of the clamping ring 208. When the gear rotates, it drives the force-bearing rack 207 to slide along the guide groove 104.

[0037] A first buffer spring 302 is fixedly connected to the inner wall of the buffer cylinder 301, a push plate 303 is fixedly connected to the bottom of the first buffer spring 302, and a connecting rod 304 is fixedly connected to the bottom of the push plate 303.

[0038] A second buffer spring 305 is fixedly connected to the bottom of the inner wall of the buffer cylinder 301. The top of the second buffer spring 305 is fixedly connected to the bottom of the push plate 303. The second buffer spring 305 is sleeved on the outer surface of the connecting rod 304.

[0039] When the first buffer spring 302 contracts to its limit, the second buffer spring 305 begins to function, providing secondary buffer protection. The first buffer spring 302 and the second buffer spring 305 form a graded buffer system. The first layer of springs absorbs the initial impact energy, and the second layer of springs responds to the remaining impact force, significantly reducing the inertial impact when the molding box 103 descends.

[0040] The implementation principle of the powder metallurgy high alloy high-speed steel wire processing equipment in this application embodiment is as follows: After the steel wire in the forming groove 105 is formed, the electric screw 101 is started and provides driving force to push the forming box 103 to slide down along the slide rail 102. The limiting function of the slide rail 102 ensures that the movement direction of the forming box 103 is stable and avoids deviation. During the descent of the forming box 103, the ejector pin 202 fixed in the center of the bottom plate 201 gradually contacts the wire in the forming groove 105. As the forming box 103 continues to descend, the ejector pin 202 pushes the formed wire out of the forming groove 105, completing the demolding action. At this time, the first buffer spring 302 in the buffer cylinder 301 is released from the compression of the push plate 303 and begins to contract. The elastic potential energy of the spring absorbs the impact energy when the forming box 103 descends, effectively slowing down the descent speed of the forming box 103, reducing equipment vibration, and improving the stability of movement.

[0041] As the molding box 103 descends, the worm 204 moves synchronously with the connecting plate 203. Since the worm wheel 205 meshes with the worm 204, the linear motion of the worm 204 is converted into the rotational motion of the worm wheel 205. The worm wheel 205 further drives the force-bearing gear 206 meshing with it to rotate, forming a power transmission chain. The force-bearing gear 206 meshes with the force-bearing rack 207 on the outside of the clamping ring 208. When the gear rotates, it drives the force-bearing rack 207 to slide along the guide groove 104, thereby driving the clamping ring 208 to open and close symmetrically in the guide groove 104. When the ejector pin 202 pushes out the wire, the clamping ring 208 closes and clamps the wire, ensuring that the wire maintains a stable position after demolding and avoiding falling off or deforming due to gravity or external force. The symmetrical design of the clamping ring 208 ensures that the wire is subjected to uniform force and prevents local damage.

[0042] During the descent of the molding box 103, the second buffer spring 305 inside the buffer cylinder 301 is linked to the connecting rod 304 via the push plate 303. When the first buffer spring 302 contracts to its limit, the second buffer spring 305 begins to function, providing secondary buffer protection. The first buffer spring 302 and the second buffer spring 305 form a graded buffer system. The first layer of springs absorbs the initial impact energy, while the second layer of springs copes with the remaining impact force, significantly reducing the inertial impact when the molding box 103 descends and extending the service life of the equipment. In addition, the connecting rod 304 rigidly connects the base plate 201 to the buffer cylinder 301, ensuring that the buffer force is evenly transmitted to the overall equipment frame and avoiding structural damage caused by local stress concentration.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
