Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, specifically to a pressure quenching device for preventing deformation of thin-walled cutting blades. Background Technology

[0002] In machine tool equipment, shear blades are very long (about 900mm). Shear blades are subjected to severe impact and friction during operation. After the blades wear out, they need to be ground, repaired, and quenched. Due to the long blade size, shear blades often become deformed after grinding and quenching, which reduces the service life of the shear blades and increases the operating cost of the shear.

[0003] Chinese invention patent CN106367570B discloses a quenching anti-deformation device and method, including a lower pressure frame and an upper pressure frame hinged together by a connecting rod, forming a space between the lower and upper pressure frames for pressing the workpiece, and the lower and upper pressure frames being pressed together by multiple clamping claws. This invention patent features a tilting ring that allows large workpieces to be heated horizontally. After heating, a lifting device hooks the tilting ring, vertically lifting the workpiece into a quenching tank for quenching, saving energy consumption and improving quenching quality.

[0004] However, the device is complex to operate, lacks a rapid positioning and automatic reset mechanism, is inefficient, and its components lack coordinated design, making it difficult to quickly complete clamping operations and failing to achieve the high-efficiency operation effect of the target device. Utility Model Content

[0005] The purpose of this invention is to provide a pressure quenching device for preventing deformation of thin-walled blades, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure quenching device for preventing deformation of thin-walled blades, comprising: clamping blocks, a communicating groove between adjacent clamping blocks, first positioning posts fixedly connected around the perimeter of adjacent clamping blocks, a connecting rod between adjacent first positioning posts, an extension rod fixedly connected to the side wall of the clamping block, a rotating groove on the inner surface of the extension rod, and mounting grooves symmetrically provided on the rotating groove, a second positioning post fixedly connected between adjacent mounting grooves, a return spring symmetrically sleeved on the outer surface of the second positioning post, the return spring and the mounting groove fixedly connected, a rotating rod fixedly connected between adjacent return springs, the rotating rod and the outer surface of the second positioning post rotatably connected, a connecting post rotatably connected inside the rotating rod, and a positioning plate symmetrically fixedly connected to the outer surface of the connecting post, the positioning plate and the clamping block fixedly connected.

[0007] Preferably, the positioning plate is located above the extension rod, and the size of the return spring corresponds to the size of the mounting groove.

[0008] Preferably, the rotating rod and the rotating groove are internally movable, and the interior of the mounting groove and the interior of the rotating groove are connected.

[0009] Preferably, the connecting rod is located between two adjacent clamping blocks, and the two adjacent connecting rods are arranged parallel to each other.

[0010] Preferably, the interior of the rotating groove is connected to the outer surface of the extension rod, and the connecting groove is located between the extension rod and the rotating rod.

[0011] Preferably, the cross-section of the connecting groove has multiple continuous concave and convex structures, and the positions of the extension rod and the rotating rod are staggered.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention balances the pressure between clamping blocks through a connecting groove. The first positioning post cooperates with the connecting rod to quickly position and stabilize adjacent clamping blocks, establishing a stable clamping foundation. The extension rod expands the clamping range, the rotating groove provides movement space for the rotating rod, and the mounting groove cooperates with the second positioning post to provide mounting support for the return spring and the rotating rod.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Reference Figures 1 to 4A pressure quenching device for preventing deformation of thin-walled blades includes: clamping blocks 1, with a connecting groove 2 between each adjacent clamping block 1 to ensure more balanced pressure transmission between adjacent clamping blocks 1 and prevent localized stress concentration that could lead to deformation of the thin-walled blade; first positioning posts 4 are fixedly connected to each of the four sides of each adjacent clamping block 1, providing stable mounting bases for connecting rods 3 and ensuring precise correspondence between the connecting rods 3 and the clamping blocks 1; and connecting rods 3 are provided between each of the two adjacent first positioning posts 4, allowing the connecting rods 3 to connect the first positioning posts 4 on adjacent clamping blocks 1 in series, thereby enhancing the overall structural stability of the combination of multiple clamping blocks 1. Qualitatively, an extension rod 5 is fixedly connected to the side wall of the clamping block 1. The extension rod 5 provides a carrier for the opening of the rotating groove 10 and the mounting groove 6, and at the same time builds a connecting bridge between the rotating rod 9 and the clamping block 1. The inner surface of the extension rod 5 has a rotating groove 10, which provides a space for the rotating rod 9 to move, ensuring that the rotating rod 9 can rotate flexibly around the second positioning post 8. The rotating groove 10 has symmetrical mounting grooves 6, which are used to accommodate the second positioning post 8 and the return spring 7, and at the same time provide an independent installation area for each component to avoid mutual interference. The second positioning post 8 is fixedly connected between each two adjacent mounting grooves 6. The second positioning post 8 serves as a support for the return spring 7. The second positioning post 8 provides a support and a rotation axis for the rotating rod 9. A return spring 7 is symmetrically fitted onto the outer surface of the second positioning post 8. The return spring 7 can drive the rotating rod 9 to return to its original position through its own elastic deformation, maintaining the initial working position of the rotating rod 9. The return spring 7 is fixedly connected to the mounting groove 6. This connection method restricts the installation position of the return spring 7, preventing it from shifting or falling off during extension and retraction. A rotating rod 9 is fixedly connected between each adjacent return spring 7. The rotating rod 9 can transmit the elastic force of the return spring 7 to the clamping area, assisting in adjusting the pressure of the clamping block 1 on the thin-walled blade. The outer surfaces of the rotating rod 9 and the second positioning post 8 are rotatably connected. Next, this connection structure allows the rotating rod 9 to swing flexibly around the second positioning post 8 as an axis, adapting to pressure adjustment requirements at different angles. The rotating rod 9 is internally connected to a connecting post 12, which enhances the connection flexibility between the rotating rod 9 and the positioning plate 11 and prevents the rotating rod 9 from getting stuck during movement. The positioning plate 11 is symmetrically fixedly connected to the outer surface of the connecting post 12. The positioning plate 11 provides stable support for the connecting post 12 and the rotating rod 9 through its fixed connection with the clamping block 1. The fixed connection between the positioning plate 11 and the clamping block 1 forms an integral force-bearing structure, improving the load-bearing capacity of the extension rod 5 area.

[0017] Reference Figures 3 to 4The positioning plate 11 is located above the extension rod 5. This position ensures that the positioning plate 11 does not interfere with the normal operation of the internal components of the rotating groove 10 and mounting groove 6 inside the extension rod 5. The size of the return spring 7 corresponds to the size of the mounting groove 6, ensuring that the return spring 7 can be fully embedded in the mounting groove 6 and that its extension and retraction movements are not restricted by space. The rotating rod 9 is internally connected to the rotating groove 10, allowing the rotating rod 9 to move freely within the rotating groove 10 and achieve dynamic adjustment of the clamping pressure. The interior of the mounting groove 6 and the interior of the rotating groove 10 are connected, facilitating the assembly and connection of the second positioning post 8, the return spring 7, and the rotating rod 9, ensuring smooth linkage of the movement of each component. The connecting rod 3 is located between two adjacent clamping blocks 1, and can directly transmit the force of the adjacent clamping blocks 1, maintaining the relative position of the multiple clamping blocks 1. The two adjacent connecting rods 3 are arranged parallel to each other, so that the force direction of each connecting rod 3 is consistent, and the clamping block 1 is prevented from tilting due to force offset. The interior of the rotating groove 10 is connected to the outer surface of the extension rod 5, providing a movable outlet for the end of the rotating rod 9, ensuring that the rotating rod 9 can extend to the designated clamping position. The connecting groove 2 is located between the extension rod 5 and the rotating rod 9, which can alleviate the interaction force between the extension rod 5 and the rotating rod 9 during movement, and prevent the two from squeezing and affecting the clamping effect of the thin-walled blade. The cross-section of the connecting groove 2 has multiple continuous concave and convex structures. This structure can enhance the compressive strength of the connecting groove 2, while dispersing the pressure transmission path and reducing local stress concentration. The positions of the extension rod 5 and the rotating rod 9 are staggered, so that they do not obstruct each other during movement, ensuring the independent realization and coordinated cooperation of their respective functions.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
