Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, specifically a high-speed steel thread plate. Background Technology

[0002] Screws are tools that use the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually fasten objects and machine parts. Screws are one of the main ways to connect and fix objects and are widely used in daily life and production. Thread plates are two square templates used on thread rolling machines. They are made of DC53 material or SKH-9 high-speed steel and consist of two pieces, one long and one short. The long plate is the movable plate, and the short plate is the fixed plate. They have threads and are used to extrude screws into threads.

[0003] Currently, high-speed steel thread rolling plates are usually used independently for thread rolling of screws. When rolling screws with different thread requirements in multiple sections, it is usually necessary to replace and adjust the thread rolling plates with different thread patterns. Due to the difference between the thread pattern of the thread rolling plate and the thread rolling position, the connection is very inconvenient when rolling multiple sections, which greatly reduces the thread rolling efficiency and accuracy of screws, resulting in a high scrap rate of screws.

[0004] Therefore, we propose a high-speed steel toothed plate to solve the above problems. Summary of the Invention

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a high-speed steel tooth plate, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A high-speed steel tooth plate includes a first tooth plate and a first tooth groove formed on the surface of the first tooth plate, and further includes: a second tooth plate movably disposed between a plurality of first tooth plates, and the surface of the second tooth plate is provided with a second tooth groove; The second toothed plate has mounting plates fixedly connected to both outer walls, and the mounting plates have multiple positioning screw holes through them. The first toothed plate has mounting grooves on both sides corresponding to the mounting plate.

[0007] Furthermore, the two mounting plates are symmetrically distributed about the central axis of the second toothed plate, and the second toothed plate is arranged parallel to one side of the first toothed plate; Multiple positioning screw holes are equidistantly spaced inside the mounting plate.

[0008] Furthermore, the bottom of the mounting groove is provided with a threaded hole, and the bottom end of the threaded hole is connected to a countersunk hole, which is fitted into the bottom end of the first toothed plate.

[0009] Furthermore, the threaded hole is located at the bottom center of the mounting groove, and the threaded hole is perpendicular to the mounting groove.

[0010] Furthermore, the length of the mounting groove is greater than that of the mounting plate, and the positioning screw hole at any position can be set to correspond to the threaded hole.

[0011] Furthermore, the internal thread of the threaded hole is connected to a fixing screw, and the outer wall of the fixing screw is also threaded to a positioning screw hole.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a high-speed steel tooth plate, which has the following beneficial effects: This invention, through the setting of the mounting plate and mounting groove, enables a stable fixed connection between the first and second thread plates, allowing multiple thread plates to be combined and installed. This achieves the combined connection of different thread grooves, facilitating the synchronous and efficient thread rolling of multi-segment screws, avoiding frequent switching of thread plates with different patterns. Moreover, the fixed connection of the thread plates ensures the accuracy of thread rolling between different patterns of multi-segment screws, greatly improving the processing efficiency and accuracy of screws.

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

[0016] Example like Figures 1-4As shown, an embodiment of this utility model proposes a high-speed steel thread rolling plate, including a first thread rolling plate 1, a first thread groove 2 formed on the surface of the first thread rolling plate 1, a second thread rolling plate 3, a second thread groove 4, a mounting plate 5, a positioning screw hole 6, a mounting groove 7, a threaded hole 8, and a countersunk hole 9. It also includes: the first thread rolling plate 1 and the second thread rolling plate 3 are both made of high-speed steel, which has high stability and facilitates efficient thread rolling of screws. The second thread rolling plate 3 is movably arranged between multiple first thread rolling plates 1, and the second thread groove 4 is formed on the surface of the second thread rolling plate 3. Under the effect of the connection between the first thread rolling plate 1 and the second thread rolling plate 3, multiple first thread rolling plates 1 and second thread rolling plates 3 can be combined into an integral thread rolling plate, which facilitates multi-segment processing of screws and improves the flexibility of screw thread rolling. To achieve flexibility and stability in the combination of the first threaded plate 1 and the second threaded plate 3, mounting plates 5 are fixedly connected to the outer walls of both sides of the second threaded plate 3. The two mounting plates 5 are symmetrically distributed about the central axis of the second threaded plate 3, and the second threaded plate 3 is set parallel to one side of the first threaded plate 1. This arrangement allows the symmetrically arranged mounting plates 5 to be precisely connected to the first threaded plate 1. At the same time, to ensure the connection stability between the mounting plates 5 and the two sides of the first threaded plate 1, multiple positioning screw holes 6 are drilled through the interior of the mounting plates 5. The multiple positioning screw holes 6 are equally spaced inside the mounting plates 5. The arrangement of multiple positioning screw holes 6 allows users to connect to the first threaded plate 1 at different positions through the positioning screw holes 6, improving the connection flexibility between the first threaded plate 1 and the second threaded plate 3 and making it easier to meet different screw threading requirements. Furthermore, mounting grooves 7 are correspondingly provided on both sides of the first toothed plate 1 relative to the mounting plate 5. Threaded holes 8 are provided at the bottom of the mounting grooves 7, located at the center of the bottom end of the mounting groove 7, and are perpendicular to the mounting groove 7. Simultaneously, to facilitate the switching of positioning screw holes 6 at different positions within the mounting groove 7, the length of the mounting groove 7 is set greater than the length of the mounting plate 5, so that any positioning screw hole 6 can be threadedly connected to the corresponding threaded hole 8. Specifically, the threaded connection inside the threaded hole 8 includes… A fixing screw is provided, and the outer wall of the fixing screw is also threaded with a positioning screw hole 6, which facilitates the fixing screw to fix the first tooth plate 1 and the second tooth plate 3 through the threaded hole 8 and the positioning screw hole 6. At the same time, in order to ensure the stability of the fixing screw inside the tooth plate, a countersunk hole 9 is connected to the bottom end of the threaded hole 8. The countersunk hole 9 is fitted into the bottom end of the first tooth plate 1. By setting the countersunk hole 9, the fixing screw can be stably fitted into the bottom of the tooth plate during fixing, avoiding interference of the fixing screw with the installation of the tooth plate above the thread rolling machine, and ensuring the applicability of the tooth plate.
