Description

Technical Field

[0001] This utility model relates to a milling cutter for manufacturing pickles, which is applicable to the production and manufacturing of pickles. Background Technology

[0002] Pickleballs, as a sporting good, are now widely used, and one of the key processes in their manufacturing is the drilling of the ball's surface. Currently, only a few manufacturers in China can provide specialized equipment for post-processing drilling of pickleballs. This equipment is typically equipped with a double-step angled drill bit. The existing drill bit design features a first step outer diameter of 3.0mm and a second step outer diameter of 7.0mm, connected by a 5mm long transition area at approximately 60°. However, this type of drill bit presents significant problems in practical use. Due to its structural design, the chips generated during cutting are large and easily fall into the inside of the pickleball, making cleaning extremely difficult. To remove chips from each pickleball, operators need to spend more than 3 minutes using various tools, which not only significantly reduces production efficiency but also significantly increases labor costs. Summary of the Invention

[0003] This utility model discloses a milling cutter for manufacturing pickles, aiming to solve the problems of difficult-to-remove debris, time-consuming cleaning, and low production efficiency generated during the drilling process of existing milling cutters used for manufacturing pickles.

[0004] The present invention adopts the following solution:

[0005] A milling cutter for manufacturing pickles includes a cutter body comprising a shank and a cutting edge. The cutting edge is provided with a first section, a second section, and a third section arranged coaxially. The outer diameters of the first, second, and third sections increase sequentially, with the first section having the smallest outer diameter and the third section having the largest outer diameter, which is adapted to fit the diameter of a circular hole on a pickle. The third section can be connected to the shank.

[0006] In this embodiment of the invention, the difference between the outer diameter of the third segment and the outer diameter of the second segment is equal to the difference between the outer diameter of the second segment and the outer diameter of the first segment.

[0007] In this embodiment of the invention, the outer diameter of the third segment is 7mm, the outer diameter of the second segment is 5mm, and the outer diameter of the first segment is 3mm.

[0008] In this embodiment of the invention, the lengths of the first and second segments are less than the length of the third segment.

[0009] In this embodiment of the invention, the length of the first segment can be the same as the length of the second segment.

[0010] In this embodiment of the invention, the length of the first segment is 3-5mm, the length of the second segment is 3-5mm, and the length of the third segment is 20-30mm.

[0011] This utility model provides a milling cutter for manufacturing pickle balls, which has the following beneficial effects: Through a three-section structural design, the milling cutter can significantly shorten the chip removal time in the hole-drilling process of pickle balls. Specifically, the chip removal time can be reduced from more than 3 minutes per chip to 5 seconds per chip, increasing production efficiency by nearly 36 times; furthermore, due to the simplification of the chip handling method, labor costs are significantly reduced, while the tool life is extended; in particular, the structural design of the milling cutter not only solves the problem of difficult chip removal, but also improves the overall machining efficiency by optimizing the cutting process. Attached Figure Description

[0012] To more clearly illustrate the technical solution of this utility model, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0015] Referring to the accompanying drawings, its core feature lies in the optimization of chip morphology and simplification of processing methods achieved through a three-section structural design. Specifically, the milling cutter of this invention comprises a shank 1 and a cutting edge, the cutting edge being formed by three coaxially arranged segments 2, 3, and 4. In one embodiment, the shank 1 is a cylindrical structure with a diameter of 8mm and a length of 70mm, primarily used for connection to the machine tool and ensuring the stability of the tool during high-speed rotation. The transition area between the shank 1 and the third segment 4 features a smooth design to prevent tool breakage or shortened service life due to stress concentration.

[0016] The cutting edge consists of three sections with progressively increasing outer diameters. The first section has an outer diameter of 3.0 mm and a length L1 ranging from 3 to 5 mm; the second section has an outer diameter of 5 mm and a length L2 ranging from 3 to 5 mm; and the third section has an outer diameter of 7 mm and a length L3 ranging from 20 to 30 mm. In a specific embodiment, the first section 2 has an outer diameter of 3 mm and a length of 4 mm; the second section 3 has an outer diameter of 5 mm and a length of 4 mm; and the third section 4 has an outer diameter of 7 mm and a length of 22 mm. This design ensures that the single-sided cutting thickness of each section is controlled within 1 mm, thereby generating elongated chips.

[0017] In practical use, the milling cutter of this invention completes the drilling of a pick ball through the following steps. In stage S1, the first section 2 cuts into the surface material of the pick ball with an outer diameter of 3mm, completing the initial cut and forming the basic hole diameter. Since the length of the first section 2 is only 4mm, its main task is to quickly complete the initial cut and guide the generated chips to the subsequent cutting edge. In stage S2, the second section 3 further enlarges the hole diameter with an outer diameter of 5mm. The cutting in this stage also maintains a single-sided cutting thickness of 1mm, making the chips slender and easy to handle. In stage S3, the third section 4 completes the final hole diameter machining with an outer diameter of 7mm. The length of the third section 4 is 22mm, and its function is not only to complete the standard hole diameter cutting but also to guide the slender chips to wrap around the cutting edge and finally converge at the shank 1. Throughout the cutting process, due to the short cutting edge lengths of the first section 2 and the second section 3, the chips quickly pass through these two sections and converge onto the long cutting edge of the third section 4. Finally, under the action of the high-speed rotation of the blade, the debris gradually wraps around the blade edge of the third section 4 and moves to the vicinity of the handle 1.

[0018] To further optimize the debris handling method, this invention features a specially designed air gun-assisted cleaning system. In actual operation, after the cutter completes drilling a hole in a pickle, the operator directly blows away the debris entangled on the cutter handle 1 using the air gun on the equipment. This design not only avoids the tedious process of manual cleaning but also significantly improves production efficiency. Experimental data shows that after using the milling cutter of this invention, the drilling and debris cleaning time for each pickle is reduced from more than 3 minutes to approximately 5 seconds, increasing production efficiency by nearly 36 times.

[0019] The three-section structural design of this utility model also has the following technical advantages. First, the outer diameter difference between the first section 2 and the second section 3, and between the second section 3 and the third section 4, is 2mm, ensuring a uniform distribution of cutting amount in each stage. This uniform distribution design effectively avoids the problem of coarse chips or accelerated tool wear caused by excessive cutting amount. Second, the 1mm single-sided cutting thickness design makes the chips generated during the cutting process slender, facilitating subsequent winding and centralized processing. In addition, the staged cutting method not only reduces the chip size but also reduces the probability of chips falling into the inside of the peak ball. Even if individual small chips fall into the inside of the peak ball, they can be quickly cleaned through the 7mm standard aperture, thus significantly reducing cleaning time.

[0020] In practical applications, the milling cutter of this invention can be widely used in the mass production of pickles. For example, after introducing this invention, a pickle manufacturer saw a significant improvement in the overall efficiency of its production line. Specifically, using the milling cutter of this invention in conjunction with automated drilling equipment for pickle processing, the drilling and cleaning time for each pickle is controlled within 5 seconds. Simultaneously, due to the simplified chip handling method, the labor costs of the production line are significantly reduced, and the tool life is extended.

[0021] Furthermore, the three-section structural design of this invention can be adjusted according to specific needs. For example, when machining pickles made of different materials, the length ratio of the first section 2, the second section 3, and the third section 4 can be adjusted to adapt to different cutting requirements. In certain special scenarios, the wear resistance of the tool can be improved by changing the coating material of the cutting edge, thereby further extending the tool's service life.

[0022] In summary, this invention successfully solves the technical challenge of removing debris during the drilling of pickle balls through a three-section structural design of the cutting edge. By optimizing the cutting process, it not only achieves the goal of high-efficiency and low-cost production but also significantly improves the overall efficiency of the production line. The technical solution of this invention has significant practical value and promotional significance, and can be widely applied in the field of pickle ball manufacturing and other similar processing scenarios.
