Description

Technical Field

[0001] The utility model relates to the field of high-speed steel wires, and more particularly to a high-speed steel wire straightening structure. Background Art

[0002] High-speed steel wire is a type of steel material with unique properties. It is primarily used in the manufacture of high-speed cutting tools, such as twist drills, taps, and milling cutters. High-speed steel wire typically contains various alloying elements, such as tungsten, molybdenum, chromium, and vanadium. These elements impart high hardness, wear resistance, and red hardness (the ability to maintain high hardness even at high temperatures). After proper heat treatment, its hardness can reach HRC60-65 or even higher, meeting the stringent wear resistance and hardness requirements of high-speed cutting tools.

[0003] Currently, some high-speed steel wires are manufactured by reducing the oxygen content in the environment, increasing the vacuum level in the environment, and using low-oxygen pure cerium with a lower oxygen content instead of conventional alloy materials. Low oxygen content helps improve the comprehensive mechanical properties of the steel wire. For example, Publication No.: CN118703872A discloses a cerium-containing high-speed steel and its preparation method (invention patent).

[0004] However, due to its special properties and application requirements, this type of high-speed steel wire requires a higher degree of accuracy in the straightening pressure during straightening. As a result, the simple straightening devices currently available on the market are often unable to accurately adjust the pressure. This is because simple devices usually use a relatively simple mechanical structure, mainly adjusting the pressure by rotating a downward pressure screw, which makes it difficult to accurately control the angle and force of rotation, resulting in inaccurate pressure adjustment.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a high-speed steel wire straightening structure. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a high-speed steel wire straightening structure.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed steel wire straightening structure, comprising a machine body, wherein an upper straightening roller and a lower straightening roller are respectively provided on the upper and lower sides of the surface of the machine body, and a downward pressure screw for adjusting the height of the upper straightening roller is provided at the top of the machine body, and a high-precision rotating mechanism is provided on the rotating end of the downward pressure screw to accurately adjust the rotation amplitude of the downward pressure screw, thereby accurately adjusting the height of the upper straightening roller.

[0008] Preferably, the high-precision rotation mechanism includes a large bevel gear fixed to the head of the downward screw, and a small bevel gear is meshed and connected to the outer wall of the large bevel gear. The surfaces of the large bevel gear and the small bevel gear are rotatably supported by bearings, and the two bearings are connected by a connecting plate. The top of the connecting plate is fixedly connected to a telescopic rod, and the head of the telescopic rod is fixed to the top of the machine body by an L-shaped plate A.

[0009] Preferably, a rotating plate is fixedly connected to the side of the small bevel gear opposite to the bearing to prevent staff from rotating the small bevel gear.

[0010] Preferably, a pressing assembly for limiting the rotation of the pressing screw is fixedly connected to the back of the machine body.

[0011] Preferably, the clamping assembly includes an L-shaped plate B fixed to the back of the machine body, and the surface of the L-shaped plate B is fixedly connected to an electric hydraulic rod that drives multiple clamping plates to move in the direction of the downward pressing screws, thereby clamping the multiple downward pressing screws at the same time.

[0012] Preferably, a transmission portion of the electric hydraulic rod is fixedly connected to a transverse plate, and an elastic buffer component is installed between the transverse plate and the pressing plate.

[0013] Preferably, the elastic buffer component includes a connecting shell fixed on the surface of the horizontal plate, and the inner sides of the connecting shell are fixedly connected with guide rails for sliding sliders, a movable plate is fixedly connected between the sliders, and a spring is fixedly connected between the back of the movable plate and the inner surface of the connecting shell. The surface of the movable plate is fixed to the back of the clamping plate through a cylindrical rod, so that the downward screw is pressed more firmly.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The utility model can accurately adjust the rotation amplitude of the pressing screw through a high-precision rotating assembly, and the pressing screw adjusts the height of the straightening roller to accurately adjust the height of the upper straightening roller, thereby adjusting the distance between the upper straightening roller and the lower straightening roller, and finally accurately adjust the pressure between the upper straightening roller and the lower straightening roller to adapt to the straightening of high-speed steel wire produced by a low-oxygen content method, thereby solving the problem that the existing simple devices in the background technology often adopt a relatively simple mechanical structure, mainly adjusting the pressure by rotating the pressing screw, and it is difficult to accurately control the angle and force of rotation, resulting in inaccurate pressure adjustment;

[0016] 2. The utility model uses a pressing assembly to simultaneously press and fix multiple pressing screws to prevent the pressing screws from rotating due to vibration during the straightening process, thereby changing the pressure on the high-speed steel wire and ultimately affecting the straightening effect of the high-speed steel wire;

[0017] 3. When the utility model is pressed, the electric hydraulic rod drives multiple pressing plates to move in the direction of the pressing screw through the cross plate and the elastic buffer component. When the pressing plate contacts the pressing screw, it will be forced to move in the opposite direction. The pressing plate drives the movable plate to move in the opposite direction through the cylindrical rod. The movable plate drives the movement of the slider. The slider slides along the guide rail to maintain the linear movement of the movable plate and squeezes the spring at the same time. The spring will form a certain rebound force when squeezed, thereby prompting the pressing plate to firmly press the pressing screw. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-4As shown, the utility model provides a high-speed steel wire straightening structure, including a machine body 1, an upper straightening roller 2 and a lower straightening roller 3 are respectively provided on the upper and lower sides of the surface of the machine body 1, a downward pressure screw 4 for adjusting the height of the upper straightening roller 2 is provided at the top of the machine body 1, and a high-precision rotating mechanism 5 is provided on the rotating end of the downward pressure screw 4 to accurately adjust the rotation amplitude of the downward pressure screw 4, thereby accurately adjusting the height of the upper straightening roller 2.

[0027] During use, the rotation amplitude of the downward pressure screw 4 can be accurately adjusted through the high-precision rotating assembly, and the height of the straightening roller can be adjusted by the downward pressure screw 4 to accurately adjust the height of the upper straightening roller 2, thereby adjusting the distance between the upper straightening roller 2 and the lower straightening roller 3, and finally accurately adjusting the pressure between the upper straightening roller 2 and the lower straightening roller 3 to adapt to the straightening of high-speed steel wire produced by low oxygen content (the high-speed steel wire passes between the upper straightening roller 2 and the lower straightening roller 3 for straightening).

[0028] The following is the specific structure of the high-precision rotation mechanism 5: the high-precision rotation mechanism 5 includes a large bevel gear 501 fixed to the head of the downward screw 4, and a small bevel gear 502 is meshed and connected to the outer wall of the large bevel gear 501. The surfaces of the large bevel gear 501 and the small bevel gear 502 are rotatably supported by bearings 503. The two bearings 503 are connected by a connecting plate 504. The top of the connecting plate 504 is fixedly connected to a telescopic rod 505, and the head of the telescopic rod 505 is fixed to the top of the body 1 through an L-shaped plate A506. The small bevel gear 502 is fixedly connected to a rotating plate 507 on the side opposite to the bearing 503.

[0029] The small bevel gear 502 can be rotated clockwise or counterclockwise by the rotating plate 507, and the large bevel gear 501 is driven by the small bevel gear 502 to rotate, and the two are supported by two bearings 503 for rotation. Due to the difference in size, when the small bevel gear 502 rotates several circles, the large bevel gear 501 will only drive the downward pressure screw 4 to rotate one circle. When the downward pressure screw 4 is rotated and moved up and down along the machine body 1, the telescopic rod 505 will be extended and retracted to cooperate with its movement. In this way, the rotation amplitude of the downward pressure screw 4 can be accurately adjusted (the downward pressure screw 4 can be rotated in a small amplitude to facilitate finding the optimal position of the upper straightening roller 2), thereby accurately adjusting the pressure between the upper straightening roller 2 and the lower straightening roller 3. In addition, the high-precision rotation mechanism 5 is simple and low in cost, and can be well used on a simple straightening machine.

[0030] The back of the straightening machine is fixedly connected with a clamping assembly 6 that limits the rotation of the downward screw 4. After the heights of multiple straightening rollers 2 on the straightening structure are adjusted, the multiple downward screws 4 can be clamped and fixed at the same time by the clamping assembly 6 to prevent the downward screw 4 from rotating due to vibration during the straightening process, thereby changing the pressure on the high-speed steel wire. The clamping assembly 6 includes an L-shaped plate B601 fixed to the back of the straightening machine, and the surface of the L-shaped plate B601 is fixedly connected with an electric hydraulic rod 602 that drives multiple clamping plates 603 to move in the direction of the downward screw 4. That is, after the downward screw 4 completes its rotation, the electric hydraulic rod 602 drives the multiple clamping plates 603 to move in the direction of the downward screw 4, thereby clamping the multiple downward screws 4 respectively to prevent the downward screw 4 from rotating due to vibration in the later stage.

[0031] Furthermore, the transmission part of the electric hydraulic rod 602 is fixedly connected with a transverse plate 604, and an elastic buffer component 605 is installed between the transverse plate 604 and the pressing plate 603. The elastic buffer component 605 includes a connecting shell 6051 fixed on the surface of the transverse plate 604, and the inner sides of the connecting shell 6051 are fixedly connected with guide rails 6052 for sliding the slider 6053. A moving plate 6054 is fixedly connected between the sliders 6053, and a spring 6055 is fixedly connected between the back of the moving plate 6054 and the inner surface of the connecting shell 6051. The surface of the moving plate 6054 is fixed to the back of the pressing plate 603 through a cylindrical rod 6056. When pressing, the electric hydraulic rod 602 is pressed through the transverse plate 604 and the elastic buffer Component 605 drives multiple clamping plates 603 to move in the direction of the downward pressing screw 4. When the clamping plate 603 contacts the downward pressing screw 4, it will be forced to move in the opposite direction. The clamping plate 603 drives the movable plate 6054 to move in the opposite direction through the cylindrical rod 6056. The movable plate 6054 drives the movement of the slider 6053. The slider 6053 slides along the guide rail 6052 to maintain the linear movement of the movable plate 6054 and squeezes the spring 6055 at the same time. The spring 6055 will form a certain rebound force when squeezed, thereby prompting the clamping plate 603 to firmly press the downward pressing screw 4. If the clamping plate 603 does not contact the downward pressing screw 4, the spring 6055 will use its elasticity to reset the movable plate 6054.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
