Description

Technical Field

[0001] This utility model relates to the field of blade technology, specifically to a high-strength, high-temperature resistant blade. Background Technology

[0002] The primary function of cold shear blades is to perform shearing operations during metal forming. They are commonly used to shear various metal materials, such as bars, wires, and structural steel, to ensure precise cutting and forming. Cold shear blades maintain a low temperature during the shearing process, thus ensuring shearing accuracy and blade durability. They are widely used in metal forming processes in industries such as metallurgy and steel. For example, in high-temperature shearing operations such as continuous casting, continuous rolling, hot forging, and billet preparation, cold shear blades can withstand the high-temperature environment and maintain shearing effectiveness. Furthermore, cold shear blades are also used in components of bar and wire baling machines and in heat-resistant and wear-resistant guide channels, improving the overall performance and durability of the equipment.

[0003] A search revealed existing technology (publication number: CN222696136U), which describes "a high-strength cold shear blade, comprising an inner T-shaped mounting bracket, a sliding hole on the upper surface of the inner T-shaped mounting bracket, a T-shaped sliding rod slidably connected to the inner wall of the sliding hole, a telescopic spring sleeved on the outer surface of the T-shaped sliding rod, a temporary storage opening on the inner top wall of the inner T-shaped mounting bracket, a T-shaped fixing bracket at the front of the inner T-shaped mounting bracket, and a cold shear blade body fixedly connected to the bottom surface of the T-shaped fixing bracket. This device, by setting up a sliding hole, a T-shaped sliding rod, a telescopic spring, and a limiting plate, utilizes the sliding connection between the T-shaped sliding rod and the sliding hole, as well as the rebound force of the telescopic spring, to easily pull the limiting plate up and down. Furthermore, the limiting plate, in conjunction with the temporary storage opening and the limiting groove, allows for convenient and quick installation and removal of the T-shaped fixing bracket and the cold shear blade body. Based on the above operations, the cold shear blade body can be easily replaced, avoiding the situation where rusted screws make disassembly difficult."

[0004] While existing high-strength cold shear blades offer convenient replacement, they still have some shortcomings: During continuous use, the blade temperature becomes high due to shearing against metal materials, leading to chipping and requiring replacement of the entire blade, resulting in high material consumption and operating costs. Furthermore, existing cold shear blades are prone to blade breakage, partly due to the high blade temperature and partly due to the blade's plate structure and material, which results in high internal stress and moment of inertia when continuous internal cutting is not possible. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, a high-strength, high-temperature resistant cutting tool is provided to solve the problems mentioned in the background.

[0006] To achieve the above objectives, a high-strength, high-temperature resistant blade is provided, comprising: a blade body, the blade body including a blade body and an independent cutting edge, the independent cutting edge being installed at the lower end of the blade body; a liquid storage chamber being formed inside the blade body, and a replenishment port being connected to the outer side of the liquid storage chamber; a flow channel being connected to the lower end of the liquid storage chamber; an insertion hole being connected to the lower end of the flow channel; and an installation groove being formed between the insertion holes; the independent cutting edge including a triangular blade body, and an installation block being connected to the upper end of the triangular blade body; connection holes being formed on both side walls of the installation block; the installation block being inserted into the corresponding installation groove; an insertion tube being connected to the upper end of the triangular blade body, and the insertion tube being inserted into the corresponding insertion hole; and the lower end of the insertion tube communicating with an arc-shaped flow channel formed inside the triangular blade body.

[0007] Furthermore, the blade is designed as a rectangular structure, and the outer wall of the blade has a threaded hole, in which a mounting bolt is connected.

[0008] Furthermore, the supplementary port is located on the outer wall of the blade, and the outer port is provided with a bolt plug.

[0009] Furthermore, when the mounting block is connected to the mounting groove, the connecting holes and threaded holes correspond one-to-one in the horizontal direction.

[0010] Furthermore, the insertion holes are symmetrically arranged about the mounting groove, and the insertion holes are offset from the threaded holes.

[0011] Furthermore, the insertion tube is provided with a flow-slowing block inside, and the flow-slowing block is designed with a funnel-shaped structure, and multiple sets of flow-slowing blocks are arranged inside the insertion tube, both vertically and horizontally.

[0012] Furthermore, the outer end of the arc-shaped flow channel is provided with an outflow port, which is located on the outer walls of both sides of the triangular blade body.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The blade body and independent cutting edge are mounted and fixed by mounting blocks and mounting slots, as well as mounting bolts and threaded holes. After long-term use, when the independent cutting edge wears down, it can be removed by unscrewing the mounting bolts. This makes it easy to replace the independent cutting edge individually, thus avoiding the need to replace the entire blade, reducing consumables and lowering the cost of use.

[0015] 2. Utilizing the internal liquid storage chamber of the blade, during use, the coolant inside the storage chamber flows downward through the distribution channel into the insertion hole, and then into the insertion pipe. Through multiple sets of flow-damping blocks inside the insertion pipe, the coolant flows downward slowly, allowing it to cool the triangular blade body by flowing downward through the arc-shaped flow channel. At the same time, the coolant flowing out through the external outlet flows downward through the outer wall of the triangular blade body, further achieving a cooling effect on the individual cutting edges. This effectively reduces the curling phenomenon caused by continuous cutting edge operation, thus reducing the frequency of consumables and replacements. Attached Figure Description

[0022] Reference Figures 1 to 5As shown, this utility model provides a high-strength, high-temperature resistant blade, comprising: a blade body 1, the blade body 1 including a blade 11 and an independent cutting edge 12, the independent cutting edge 12 being installed at the lower end of the blade 11; a liquid storage cavity 112 being formed inside the blade 11; a replenishment port 111 being connected to the outer side of the liquid storage cavity 112; a flow channel 113 being connected to the lower end of the liquid storage cavity 112; a insertion hole 115 being connected to the lower end of the flow channel 113; and an installation groove being formed between the insertion holes 115. 116. The independent cutting edge 12 includes a triangular cutting body 121, and the upper end of the triangular cutting body 121 is connected to a mounting block 123. The mounting block 123 has connecting holes 1231 on both sides. The mounting block 123 is inserted into the mounting groove 116. The upper end of the triangular cutting body 121 is connected to a plug tube 122, and the plug tube 122 is inserted into the plug hole 115. The lower end of the plug tube 122 is connected to the arc-shaped flow channel 1211 opened inside the triangular cutting body 121.

[0023] In this embodiment, the blade 11 and the independent cutting edge 12 constitute the high-strength, high-temperature resistant blade body 1 structure involved in this application.

[0024] The blade body 11 is made of steel, and the independent cutting edge 12 is made of tungsten alloy, which gives the blade body 11 good structural toughness, while the independent cutting edge 12 has high strength, wear resistance and high temperature resistance. At the same time, an anti-corrosion coating is provided on the outer wall of the blade body 1.

[0025] Specifically, the mounting slot 116 is a rectangular slot, and the mounting block 123 is a rectangular block. The length and width of the mounting block 123 are smaller than the length and width of the upper end face of the independent blade 12.

[0026] Specifically, the cross-section of the independent cutting edge 12 is designed as an isosceles triangle structure, and the mounting block 123 is located on the upper end face of the independent cutting edge 12, and the mounting block 123 and the independent cutting edge 12 are designed as an integral structure.

[0027] It should be noted that the independent blade 12, as well as the mounting block 123 and the insertion pipe 122, are prefabricated. The slots and structures are known before the independent blade 12 is installed, which allows for quick switching when the independent blade 12 is replaced, and then the replaced independent blade 12 can be repaired again.

[0028] It should be noted that irregular recessed patterns are provided on the outer wall of the blade body 1, which enhances the structural toughness of the blade body 1 and reduces the effect of chipping.

[0029] like Figures 1 to 4In the process, the blade 11 is a rectangular structure, and the outer wall of the blade 11 has a threaded hole 114, and a mounting bolt 117 is connected in the threaded hole 114. The outer port of the supplement port 111 is located on the outer wall of the blade 11, and the outer port is provided with a bolt plug. When the mounting block 123 is connected to the mounting groove 116, the connecting hole 1231 and the threaded hole 114 correspond one-to-one in the horizontal direction. The insertion hole 115 is symmetrically arranged about the mounting groove 116, and the insertion hole 115 and the threaded hole 114 are staggered. The insertion tube 122 is provided with a flow-slowing block 1221 inside, and the flow-slowing block 1221 is a funnel-shaped structure. Multiple sets of flow-slowing blocks 1221 are arranged vertically inside the insertion tube 122. The outer end of the arc-shaped flow channel 1211 is provided with an outflow port 124, and the outflow port 124 is located on both sides of the outer wall of the triangular blade 121.

[0030] Specifically, the inner wall of the replenishment port 111 is provided with internal threads, so that it can be screwed and fixed with the bolt plug to achieve a seal on the liquid storage chamber 112.

[0031] It should be noted that a through hole is opened inside the bolt plug, and a breathable membrane material is provided in the through hole to enable communication between the liquid storage chamber 112 and the outside air, thereby facilitating the flow of coolant under external air pressure.

[0032] Specifically, multiple sets of insertion pipes 122 are provided, and multiple sets of corresponding arc-shaped flow channels 1211 are provided, which increases the contact area between the inside of the triangular blade body 121 and the coolant, thereby improving the cooling effect. At the same time, the connection between multiple sets of insertion pipes 122 and insertion holes 115 facilitates the improvement of the stability of the connection between the mounting groove 116 and the mounting block 123.

[0033] Specifically, the flow-slowing block 1221 is made of metal and is integrated with the insertion pipe 122. Flow-slowing holes are provided at the bottom of the funnel-shaped cavity of the flow-slowing block 1221.

[0034] As a preferred implementation, by setting the arc-shaped flow channel 1211, the coolant can enter the interior of the independent blade 12 to achieve internal cooling. Secondly, the arc-shaped flow channel 1211 increases the strength and rigidity of the independent blade 12 by drilling holes, reduces its moment of inertia, and thus improves the structural toughness of the independent blade 12.

[0035] In use, the blade body and independent cutting edges are mounted and fixed by mounting blocks and mounting slots, as well as mounting bolts and threaded holes. After long-term use and wear of the independent cutting edges, they can be removed by unscrewing the mounting bolts, facilitating individual replacement. A liquid reservoir inside the blade body allows coolant to flow downwards through a distribution channel into the insertion hole and then into the insertion pipe. Multiple flow-damping blocks inside the insertion pipe slow the coolant downwards, allowing it to cool the triangular blade body through an arc-shaped flow channel. Simultaneously, coolant flowing out through the external outlet flows downwards along the outer wall of the triangular blade body, further cooling the independent cutting edges. This effectively reduces edge curling caused by continuous operation, lowering the frequency of consumables and replacements.

[0036] The high-strength, high-temperature resistant blade of this invention can effectively solve the problems mentioned in the background technology. It achieves the effect of independent blade replacement on the basis of existing high-strength, high-temperature resistant blade technology, and has the effect of cooling the blade. At the same time, it increases the strength and high-temperature resistance of the blade.
