Description

Technical Field

[0001] This utility model relates to the field of metal cutting equipment technology, and in particular to a cutting lathe for cemented carbide materials. Background Technology

[0002] In the current field of metal cutting, lathes for cutting cemented carbide materials are usually equipped with mold assemblies to realize cutting actions. By mounting the mold assembly on the corresponding mounting structure of the lathe, the mold is rotated or moved by the power drive mechanism of the lathe, thereby performing cutting operations on the cemented carbide workpiece.

[0003] In existing technologies, the connection between mold components and lathe mounting structures mostly relies on traditional bolt fixing, welding, or complex snap-fit ​​structures. When it is necessary to replace or repair the mold, it is necessary to remove the bolts one by one with tools such as wrenches. The operation is cumbersome, and the disassembly process is prone to problems such as bolt corrosion and stripping, which prolongs downtime and seriously affects processing efficiency. Even if a snap-fit ​​structure is used in some cases, the snap-fit ​​release operation is complicated and it is difficult to quickly release the lateral or vertical limit of the mold, which is not conducive to the rapid replacement of the mold. In order to improve this, a cutting lathe for cemented carbide materials is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting lathe for cemented carbide materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A machining lathe for cutting cemented carbide materials includes an upper mounting plate, a lower mounting plate, an outer cutting die, and an inner cutting die mounted on the lathe. The upper mounting plate has a mounting opening, and the upper end face of the lower mounting plate has two movable grooves. Each of the two movable grooves has a limiting plate installed through a pressing mechanism. The mounting opening has an annular groove and a rotating groove. A rotary motor is installed in the rotating groove and is connected to the lower mounting plate through a rotating mechanism. Both the upper and lower mounting plates have mounting grooves. The outer cutting die has a pressing groove, and a positioning block is installed in the pressing groove through a pressing mechanism. The bottom of the lower mounting plate has a positioning hole. The inner cutting die is connected to the outer cutting die through a connecting mechanism.

[0006] Preferably, the extrusion mechanism includes a horizontal spring disposed in the movable groove, the two ends of which are elastically connected to the inner sidewall of the movable groove and the vertical outer wall of the limiting plate, respectively.

[0007] Preferably, the rotating mechanism includes a gear disposed on the output shaft of the rotary motor, and a gear ring is provided on the upper end face of the lower mounting plate, the gear meshing with the gear ring.

[0008] Preferably, the pressing mechanism includes a vertical spring disposed in the pressing groove, and the two ends of the vertical spring are elastically connected to the inner wall of the pressing groove and the outer wall of the positioning block, respectively.

[0009] Preferably, the connecting mechanism includes connecting blocks disposed on the outer walls of both sides of the inner cutting mold, and connecting grooves are provided on the surfaces of the outer cutting mold corresponding to the inner cutting mold.

[0010] Preferably, the vertical cross-sectional view of the mounting groove is inverted T-shaped, the vertical cross-sectional view of the portion of the external cutting mold located in the mounting groove is also inverted T-shaped, and the vertical cross-sectional views of the movable groove and the limiting plate are both L-shaped.

[0011] The beneficial effects of this utility model are: By optimizing the design of the extrusion mechanism, pressing mechanism, and connecting mechanism, rapid assembly and disassembly of the mold assembly and mounting plate, as well as between the internal and external molds, are achieved. Pressing down the positioning block releases the horizontal limit of the external cutting mold, allowing for lateral movement and disassembly of the external cutting mold, simultaneously causing the internal cutting mold to detach. Moving the limit plate to compress the horizontal spring releases the vertical limit of the lower mounting plate, enabling rapid separation between mounting plates without the need for complex tools. This significantly reduces mold replacement and equipment maintenance time, improving production efficiency.

[0012] The rotating mechanism adopts a gear and gear ring meshing transmission method, which has higher transmission efficiency and can ensure the stable rotation of the lower mounting plate and mold assembly, effectively improving the cutting accuracy of cemented carbide materials. At the same time, the extrusion mechanism pushes the limiting plate into the annular groove through the horizontal spring, and the pressing mechanism pushes the positioning block into the positioning hole through the vertical spring. The double limiting structure can ensure the firmness of the connection between the mounting plates and between the mold and the mounting plate, avoiding loosening and displacement during long-term use, and further ensuring processing stability.

[0013] The mounting slot adopts an inverted T-shaped vertical section design, which effectively limits the corresponding shape of the external cutting mold, allowing it to move only laterally for assembly and disassembly, thus avoiding directional deviation during mold installation. The movable slot and the limiting plate adopt an L-shaped vertical section design, which allows the operator to directly move the limiting plate to complete the limit release operation without the need for additional tools, simplifying the operation process and reducing the difficulty of operation for the operator.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A cutting lathe for cemented carbide materials includes an upper mounting plate 1, a lower mounting plate 3, an outer cutting die 5, and an inner cutting die 6 mounted on the lathe. The above components can be installed in appropriate positions on the lathe and can be installed using existing mature components such as bolts.

[0018] The upper mounting plate 1 has a mounting opening 2, and the upper end face of the lower mounting plate 3 has two movable grooves 12. Each of the two movable grooves 12 has a limiting plate 13 installed in it through a pressing mechanism. The mounting opening 2 has an annular groove 7 and a rotating groove 14. The rotating groove 14 has a rotary motor 15 installed in it. The rotary motor 15 is connected to the lower mounting plate 3 through a rotating mechanism. Both the upper mounting plate 1 and the lower mounting plate 3 have mounting grooves 4. The outer cutting mold 5 has a pressing groove 9. The pressing groove 9 has a positioning block 10 installed in it through a pressing mechanism. The bottom of the lower mounting plate 3 has a positioning hole 11. The inner cutting mold 6 is connected to the outer cutting mold 5 through a connecting mechanism.

[0019] The extrusion mechanism includes a horizontal spring installed in the movable groove 12. The two ends of the horizontal spring are elastically connected to the inner side wall of the movable groove 12 and the vertical outer wall of the limiting plate 13, respectively. The horizontal spring realizes the extrusion operation of the limiting plate 13, which can extrude the limiting plate 13 into the annular groove 7, thereby realizing the stable installation of the lower mounting plate 3 in the mounting opening 2.

[0020] The rotating mechanism includes a gear 16 mounted on the output shaft of the rotary motor 15, and a gear ring 8 on the upper end face of the lower mounting plate 3. The gear 16 meshes with the gear ring 8, as shown in the figure. The teeth of the gear ring 8 are set on its arc-shaped outer wall. With the help of the gear 16 and the gear ring 8, the lower mounting plate 3 can be driven to rotate after the rotary motor 15 is started.

[0021] The pressing mechanism includes a vertical spring installed in the pressing groove 9. The two ends of the vertical spring are elastically connected to the inner wall of the pressing groove 9 and the outer wall of the positioning block 10, respectively. The vertical spring realizes the pressing operation of the positioning block 10, which can push it out of the pressing groove 9 and push it into the positioning hole 11, so as to realize the stable connection between the outer cutting mold 5 and the lower mounting plate 3.

[0022] The connecting mechanism includes connecting blocks 17 set on the outer walls of both sides of the inner cutting mold 6. The outer cutting mold 5 and the inner cutting mold 6 have connecting grooves 18 on their corresponding surfaces. By inserting the connecting blocks 17 into the connecting grooves 18, a stable connection between the inner cutting mold 6 and the outer cutting mold 5 is achieved.

[0023] The vertical cross-section of the mounting groove 4 is inverted T-shaped, and the vertical cross-section of the part of the outer cutting mold 5 inside the mounting groove 4 is also inverted T-shaped. This design has a certain limiting effect, so that the outer cutting mold 5 can only move laterally to complete the disengagement operation from the mounting groove 4. The vertical cross-sections of the movable groove 12 and the limiting plate 13 are both L-shaped, and their L-shaped design makes it convenient for the operator to move the limiting plate 13.

[0024] When this utility model is used, the cutting mold consists of two outer cutting molds 5 and one inner cutting mold 6. After the upper mounting plate 1 is installed on the lathe, the rotary motor 15 is started, which can drive the gear 16 to rotate. The gear 16, in conjunction with the gear ring 8, can drive the lower mounting plate 3 to rotate, thereby realizing the rotation operation of the cutting mold.

[0025] After the positioning block 10 is positioned in the positioning hole 11, the positioning block 10 can push the vertical spring and enter the lower pressure groove 9, while disengaging from the positioning hole 11. This releases the horizontal limit of the outer cutting mold 5 at any time. The mounting groove 4 on the upper mounting plate 1 is adjusted to correspond with the mounting groove 4 on the lower mounting plate 3. Then, the outer cutting mold 5 can be moved laterally to achieve the disassembly operation. When the outer cutting mold 5 is moved for disassembly, the connecting block 17 disengages from the connecting groove 18, thereby realizing the disassembly operation of the inner cutting mold 6.

[0026] When the limiting plate 13 in the movable groove 12 is moved, the limiting plate 13 squeezes the horizontal spring. After the horizontal spring is compressed, the limiting plate 13 moves within the movable groove 12, and the part in the annular groove 7 disengages. Then the lower mounting plate 3 loses its vertical limit, and the lower mounting plate 3 can be disassembled from the upper mounting plate 1 vertically.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
