Problems solved by technology

[0004] In short, the deficiencies in the prior art disclosed by the above patents are as follows: ① most of the existing rubber tapping tools are based on the transformation of milling cutters, and the difference in cutting characteristics caused by the difference in the structure of wood fibers and metal materials is not considered; ② the existing rubber tapping tools Due to the unreasonable design of the angle parameters, the cutting surface is not smooth enough, and the direction of the cutting surface is not conducive to the flow and collection of glue; ③ Most of the existing rubber tapping tools have unreasonable clamping structure design, low coaxiality, poor disassembly performance and poor processing Difficulty; ④Most of the existing rubber tapping tools are integrated, and the entire tool needs to be replaced after one blade is damaged, which increases the cost and causes waste, and cannot change the angle of the tool in time with the different glue flow conditions caused by environmental changes such as temperature, humidity, and seasons. Installation structure; ⑤ Most of the existing rubber tapping tools only have side cutting edges, and the blunt cutting edges on the end face of the tool do not damage the side of the trunk, which is not conducive to sustainable production

specific Embodiment 1

[0047] Specific embodiment 1 (two-stage blade insert type special high-speed rubber tapping tool 1)

[0048] The calculation process of the tapping removal efficiency is established, and the ratio of the cutting amount of the first cutting edge 103a and the second cutting edge 103b is determined, which is used to guide the design of the relevant parameters of the first cutting edge 103a and the second cutting edge 103b.

[0049] The overall removal efficiency of the special high-speed rubber tapping tool 1 for the two-stage blade insert type is determined by the formula (1):

[0050]

[0051] In formula (1), P is the overall removal efficiency of the special high-speed rubber tapping tool with two-stage inserts (mm) 3 / min)α p is the depth of cut (mm), α e is the cutting width (mm), α f is the feed rate (mm / z), V f is the cutting speed (z / min), h is the actual depth of cut (mm), α 2 is the second relief angle, d is the actual cutting width (mm), and λ is the first edge...

specific Embodiment 2

[0075] Specific embodiment 2 (two-stage integral type special high-speed rubber tapping tool 2)

[0076] like Image 6 As shown, the geometric features of the two-section integral type high-speed rubber tapping tool 2 are the same as those of the two-section blade insert type special high-speed rubber tapping tool 1. The rubber tapping blade is driven to rotate by the motor, and the two cutting edges are in contact with the rubber skin and flow out from the rake face. . Using the integral design, in the manufacturing process, the blank is blanked, and the turning and grinding processes are directly formed, which avoids the cumbersome inlaying process; the material casting or powder metallurgy process makes there is no gap between the blade and the cutter head. It ensures the overall strength and stability of the tool, and avoids wood chips flowing into the gap to contaminate or affect the assembly process.

[0077] The material of the rubber tapping tool is high-speed steel,...

Abstract

The invention relates to the field of rubber cutting production, in particular to a rubber tapping tool with two cutting edges, which uses motor control to automatically cut rubber trees with high quality, high efficiency and protection. The invention provides an inlaid two-section cutting edge rubber tapping tool matched with a motor, and the tool is composed of a milling cutter head, a cutter shank and a blade. The mosaic design can adapt to different rubber tapping environments, and flexibly choose blades with different structures and angles to meet the needs of rubber tapping; According to the cutting requirements, a smooth and flat cutting plane is obtained, which is convenient for glue discharge, heat dissipation and chip removal; the design of the two cutting edges ensures the smoothness of the cutting plane and the side surface, and the rubber tree is not damaged; the inclination angle of the cutting edge makes the glue liquid No leakage from the side, ensuring the output.

Description

technical field [0001] The invention relates to a rubber tapping tool, in particular to a rubber tapping tool with multiple cutting action surfaces which is simultaneously provided with end face cutting and side cutting processing methods. Background technique [0002] Natural rubber is an important strategic resource and is widely used in military and national defense. At present, natural rubber production mainly relies on manual rubber tapping. The traditional "V" type rubber tapping knife is used to cut rubber trees. At the same time, the rubber tapping work can only be carried out in the early hours of the morning. The work is intensive and requires workers to have rich experience. Bark and part of the yellow bark, and make sure not to cut into the cambium to damage the tree. At the same time, the operation efficiency of workers is not high. It takes more than 30 seconds to cut a tree. The low efficiency leads to high costs. Now, the number of rubber tapping workers is ...
