Description

Technical Field

[0001] This utility model belongs to the technical field of kitchenware processing equipment, and more specifically, it relates to a tool for processing wooden pot lids. Background Technology

[0002] In the cookware industry, pot lids, as accessories to cookware, are mainly divided into two categories in terms of materials: metal and wood. Among them, metal pot lids, thanks to the plasticity of metal, can easily form a variety of aesthetically pleasing shapes on the surface of the lid through stamping processes (such as multi-ring concentric protrusions, patterned grooves, etc.). These shapes not only enhance the structural stability of metal pot lids but also significantly improve their aesthetic appeal, meeting consumers' demands for the appearance of cookware, and therefore have a strong competitive advantage in the market.

[0003] In contrast, wooden pot lids also hold a certain market share due to their good heat retention, lack of metal-to-pot friction, and gentle feel. However, limited by the material properties of wood and traditional processing methods, most mainstream wooden pot lids on the market currently adopt a basic "single-piece flat" design. This means that only the wood raw material is cut and sanded to form a flat round or square lid, without any additional three-dimensional shapes or decorative structures on the surface. This simple flat design makes wooden pot lids far less aesthetically pleasing than stamped metal pot lids, and they are gradually failing to meet the current consumer demand for cookware that combines practicality and aesthetics, leading to a decline in their market competitiveness.

[0004] To improve the appearance defects of wooden pot lids and enhance their market competitiveness, some manufacturers have attempted to replicate the three-dimensional shapes of metal pot lids (such as concentric rings) on the surface of wooden pot lids. Currently, the main processing method is "engraving," which involves milling or carving the pre-set shape onto the surface of the wooden pot lid using CNC engraving machines or manual carving. However, this engraving method is time-consuming and expensive, leading to a significant increase in the production cost of wooden pot lids. Even if the appearance is improved, the lack of price competitiveness makes it difficult to widely promote them in the market.

[0005] Therefore, there is an urgent need to develop a tool for processing wooden pot lids that can quickly process the shape of the pot lid and effectively control the processing cost, so as to solve the problem of insufficient competitiveness in the current wooden pot lid market. Utility Model Content

[0006] The purpose of this utility model is to provide a tool for processing wooden pot lids, which aims to solve the problem of high processing costs for wooden pot lids in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a tool for processing wooden pot lids, comprising: A center drill rod, wherein a drill bit is provided at the lower end of the center drill rod and an assembly part for assembly with the spindle of a drilling machine is provided at the upper end of the center drill rod; There are two wing plates, which are fixed to the central drill rod and symmetrically arranged with respect to the center of the drill rod. Each wing plate is detachably connected to multiple planing blades, which are arranged along the extension direction of the wing plate.

[0025] Please see Figures 1 to 3This invention provides a tool for processing wooden pot lids. The tool includes a central drill rod 1 and a wing plate 2. The lower end of the central drill rod 1 is equipped with a drill bit 11, which has a four-sided pointed tip. The drill bit 11 is used to drill positioning holes on the surface of the wood blank during the initial processing stage. In subsequent processing, the central drill rod 1 is confined within the positioning holes, thus positioning the tool and ensuring that the tool will not experience shaping errors due to positional shifts during subsequent cutting. Additionally, the machined positioning holes can be used to install pot lid handles in subsequent processing. The upper end of the central drill rod 1 is equipped with an assembly part for assembling with a drilling machine spindle. In this embodiment, the assembly part is a threaded shaft 12, which is fixed to the central drill rod 1 by bolting or welding. It can be stably connected to a conventional drilling machine spindle via threads, achieving uniform transmission of drilling power to the tool and ensuring stable tool speed during processing. The wing plate 2... The quantity is set to two, with two wing plates 2 fixed to the central drill rod 1 and distributed symmetrically with respect to the central drill rod 1. This symmetrical structure can balance the centrifugal force when the tool rotates at high speed and prevent unevenness of the machined surface due to the shift of the center of gravity. On each wing plate 2, along its extension direction, that is, from the central drill rod 1 to the end of the wing plate 2, multiple planing blades 3 are detachably connected. The cutting edge of the planing blades 3 is set downward, and the planing blades 3 are set at an acute angle to the horizontal plane and are located above the drill bit 11. By setting the planing blades 3 above the drill bit 11, it can be ensured that after the drill bit 11 completes the positioning, the planing blades 3 can immediately follow up to continuously cut the surface of the wooden pot lid, avoiding the disconnect between the positioning and cutting processes and reducing ineffective operation time. In actual operation, tungsten carbide blades can be used for the planing blades 3. Tungsten carbide blades have high hardness, good wear resistance and heat resistance, and stable cutting operation.

[0026] This utility model provides a tool for processing wooden pot lids. Compared with the prior art, the tool can be precisely positioned before cutting by the drill bit 11 at the lower end of the central drill rod 1 and the planer blades 3. By setting two centrally symmetrical wing plates 2 and arranging multiple planer blades 3 in the extending direction of the wing plates 2, multiple planer blades 3 can simultaneously perform ring cutting on the surface of the wooden pot lid blank when the tool rotates at high speed. The concentric ring shape is formed by continuous cutting on the surface of the wooden pot lid blank in one go, which greatly shortens the shaping and processing time of a single wooden pot lid and reduces the manufacturing cost.

[0027] In some embodiments, please refer to Figures 1 to 3A fixing plate 4 is installed at the upper end of the central drill rod 1. The fixing plate 4 is perpendicular to the central drill rod 1 (i.e., the fixing plate 4 is horizontal) and is fixed by welding or bolting. In this embodiment, the threaded shaft 12 is located above the fixing plate 4, and a hexagonal nut 121 is fitted at the lower end of the threaded shaft 12. The hexagonal nut 121 is welded to the fixing plate 4. By setting the hexagonal nut 121, it is convenient for operators to install the tool using tools such as wrenches. In this embodiment, both wing plates 2 are inclined and fixed by welding between the lower surface of the fixing plate 4 and the outer wall of the central drill rod 1, forming a triangular support structure between the central drill rod 1, wing plates 2, and fixing plate 4. This avoids the wing plates 2 from deforming during high-speed rotation due to relying only on a single point connection with the central drill rod 1, and improves the overall structural strength of the tool.

[0028] In this embodiment, the planer blade 3 is tightly attached to the surface of the wing plate 2, that is, the planer blade 3 and the wing plate 2 are arranged parallel to each other. In this way, the tilt angle of the wing plate 2 is the cutting angle of the planer blade 3. In this embodiment, the angle between the wing plate 2 and the horizontal plane is defined as the cutting angle, and the degree of the cutting angle is set between 105° and 125°. In actual processing, if the wood being processed is softwood such as pine or fir, the cutting angle can be set between 105° and 110°, which makes it easier for the cutting edge of the planer blade 3 to cut into the wood and reduce the wear of the planer blade 3. If the wood being processed is hardwood such as oak or walnut, the cutting angle can be set between 115° and 125° to enhance the cutting force of the cutting edge of the planer blade 3 and avoid cutting jamming caused by the high density of hardwood, while reducing the wear of the cutting edge caused by excessive compression. If the wood being processed is medium hardness wood, the cutting angle can be set between 110° and 115°, so that the planer blade 3 can balance cutting efficiency and surface quality.

[0029] In this embodiment, please refer to Figures 1 to 3 Each wing plate 2 is divided into a dedicated assembly area 201, which is located on one side of the central drill rod 1. The planing blades 3 are all concentrated in the assembly area 201. In this embodiment, the planing blades 3 are installed on the opposite end faces of the two assembly areas 201. A clearance notch 41 is provided between the fixed plate 4 and the wing plate 2 corresponding to the assembly area 201. In this embodiment, the clearance notch 41 is a U-shaped groove provided on the edge of the fixed plate 4. In application, the clearance notch 41 covers the space above the assembly area 201. When the planing blades 3 are installed in the assembly area 201, their upper ends will not collide with the fixed plate 4.

[0030] In this embodiment, multiple hole groups are spaced apart along the length direction of the flange 2 on the assembly area 201. The length direction of the flange 2 is the radial direction from the central drill rod 1 to the end of the flange 2. Each hole group corresponds to a preset cutting radius (such as the radius of a certain ring of a concentric ring). A single hole group contains three through holes 21 spaced apart along the width direction of the flange 2. Multiple hole groups form a "radius adjustment matrix". In application, the planer blade 3 is selectively installed on the hole group through a fastening component. By setting multiple hole groups, "large-range radius coarse adjustment" can be achieved. For example, when machining three concentric rings, only the planer blade 3 needs to be installed in the corresponding hole group, without replacing the flange 2 or the cutting tool.

[0031] In this embodiment, the planer blade 3 has an elongated hole 31 extending through its length in the middle. The fastening assembly includes a bolt 7 and a nut 8. The length direction of the elongated hole 31 is consistent with the width direction of the wing plate 2, and the width is adapted to the diameter of the shank of the bolt 7. When the planer blade 3 is installed, when the bolt 7 passes through the through hole 21 and the elongated hole 31, the planer blade 3 can move slightly along the length direction of the elongated hole 31 to adjust the cutting depth of the planer blade 3.

[0032] In this embodiment, the specific assembly process of the planer blade 3 is as follows: First, the planer blade 3 is attached to the mounting surface of the assembly area 201, so that the elongated hole 31 of the planer blade 3 is aligned with the through hole 21 of the target hole group; then, the bolt 7 is inserted from the outside of the wing plate 2 into the through hole 21, and then through the elongated hole 31 of the planer blade 3; finally, the nut 8 is screwed into the inside of the planer blade 3 until the bolt 7 and the nut 8 are completely locked, pressing the planer blade 3 tightly onto the mounting surface of the assembly area 201.

[0033] In some embodiments, the wing plate 2 is further provided with a first chip removal notch 202. The first chip removal notch 202 is located on one side of the assembly area 201 and is arranged opposite to the assembly area 201 on the other wing plate 2. In application, by setting the first chip removal notch 202, on the one hand, the side wood chips generated by cutting can directly enter the first chip removal notch 202 of the opposite wing plate 2 and then be thrown out by the centrifugal force of rotation; on the other hand, the opening of the first chip removal notch 202 provides working space for the installation tool operation. For example, when changing the planer blade 3 of the left wing plate 2, the first chip removal notch 202 of the right wing plate 2 is directly opposite the left assembly area 201. The installation tool can be inserted from the right notch and directly contact the fastening component on the left without having to avoid the wing plate 2 body.

[0034] In some embodiments, please refer to Figures 1 to 3To enhance the structural strength of the cutting tool, a connector 5 is provided between the two assembly areas 201 of the two wing plates 2. In this embodiment, the connector 5 is a structural block fitted onto the central drill rod 1. The two ends of the structural block are fixed to the edges of the two assembly areas 201 near the central drill rod 1 by welding. In this embodiment, a reinforcing plate 6 is also fixed between the ends of the two wing plates 2 on the same side and the fixing plate 4. In application, the lengths of the wing plates 2 and the fixing plate 4 are the same. Both the wing plates 2 and the fixing plate 4 extend radially with the central drill rod 1 as the origin. The two ends of the wing plates 2 are the main stress points when the wing plates 2 are cutting at high speed. By welding, one end of the reinforcing plate 6 is fixed to the end face of the wing plate 2, and the other end is fixed to the end face of the fixing plate 4, forming a triangular structural support unit of "wing plate 2, reinforcing plate 6, and fixing plate 4", which provides strong support for the wing plates 2 and improves the overall structural strength of the cutting tool.

[0035] In this embodiment, a second chip removal notch 61 is provided in the middle of the reinforcing plate 6. The second chip removal notch 61 is arranged in a near-triangular shape, and all three tips of the second chip removal notch 61 are rounded to avoid stress concentration. The second chip removal notch 61 covers 1 / 3 to 1 / 2 of the middle part of the reinforcing plate 6, ensuring sufficient chip removal space while retaining at least half of the plate area to bear the supporting function, thus preventing a decrease in strength. During processing, some wood chips generated from cutting will be diverted along the outer side of the transverse wing plate 6 under the action of centrifugal force and discharged through the second chip removal notch 61.

[0036] In this embodiment, a scribing cutting edge 62 is provided at the bottom of both reinforcing plates 6. The two scribing cutting edges 62 are symmetrically arranged with respect to the center of the central drill rod 1. In this embodiment, the vertical height of the tip of the scribing cutting edge 62 is slightly lower than the bottom of the drill bit 11 and slightly higher than the cutting edge of the planer blade 3. This height difference ensures that during processing, the drill bit 11 first completes the drilling of the positioning hole to achieve tool positioning and avoid the wood from shifting during scribing. The tip of the scribing cutting edge 62 then scribes the line outside the positioning hole, which on the one hand delineates the processing area of ​​the wooden pot lid, and on the other hand, the scribing cutting edge 62 can also pre-cut the surface fibers of the wood to form a stress relief groove, reducing the cutting resistance when the planer blade 3 cuts.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
