Description

Technical Field

[0001] The present invention relates to the technical field of saw blade tooth spacing, and more particularly to a fully automatic tooth spacing device for cemented carbide band saw blades. Background Art

[0002] A cemented carbide band saw blade is a high-precision, highly wear-resistant band saw blade used for metal cutting. The saw teeth surface is inlaid with cemented carbide, so it has extremely high hardness and durability, and is widely used in fields such as steel, cast iron, metal processing, and wood processing. Cemented carbide band saw blades are usually used for cutting materials with higher hardness, and have excellent cutting performance and long service life; during the tooth spacing process of the rack, the teeth have been cut out and present a certain preliminary tooth shape. At this time, the tooth spacing process mainly uses equipment to perform left and right extrusion on the formed tooth part, so that the teeth of each tooth shape are no longer parallel, but present a certain deflection angle or offset, so that each tooth shape of the rack or gear can be on different planes. This process can not only improve the meshing of the gear, but also improve the load capacity and working efficiency of the gear.

[0003] When the existing saw blade tooth spacing equipment extrudes and spaces the saw blade, the saw blade is prone to shaking, which will cause the tooth spacing pressure and position to be unstable, affecting the tooth shape consistency, saw blade life, and final tooth spacing quality, and even posing a safety hazard.

[0039] In a preferred embodiment, during use, the saw blade to be tooth-spaced is placed in the placement groove 2. The first motor 311 drives the first runner 308 to rotate, thereby driving the first moving seat 301 to swing left and right through the first eccentric shaft 309, and the tooth teeth are squeezed and spaced by the tooth-spacing block 304. And when the first motor 311 drives the first moving seat 301 to move towards the saw blade for tooth spacing, the toothed plate 317 is driven to move synchronously, thereby driving the gear 316 to drive the elliptical block 315 to rotate half a turn, so that the long axis end of the elliptical block 315 contacts the surface of the first push block 313, driving the first push block 313 to drive the clamping block 312 to move towards the saw blade, thereby synchronously clamping and fixing the saw blade, ensuring the stability of tooth spacing, avoiding shaking of the toothed bar, and ensuring the quality of tooth spacing.

The rotating shaft 402 is hollow, and a plurality of through holes 404 are opened on the side wall of the rotating shaft 402 for injecting oil into the brush roller 403.

[0041] Refer to Figures 1 - 9As shown, in a preferred embodiment, guide rods 405 are symmetrically and fixedly installed in the inner cavity of the clamping block 312.

When the second motor 506 drives the second moving seat 501 to move forward, the second push block 513 is driven to move forward synchronously, so as to drive the fourth connecting rod 514 and the second piston 512 to move, inject the air in the cylinder 511 into the spray pipe 509, and jet air to remove debris on the surface of the saw blade through the spray holes 510, preventing scratches from being generated when the debris remaining on the surface of the saw blade contacts the tooth spacing block 304 and ensuring the quality of the saw blade.

[0047] Specifically, the working principle of the fully automatic tooth separation equipment of the carbide band saw blade is as follows: when in use, the saw blade to be toothed is placed in the placement groove 2, and the first motor 311 drives the first rotating wheel 308 to rotate, thereby driving the first movable seat 301 to swing left and right through the first eccentric shaft 309, and the teeth are squeezed and separated by the tooth separation block 304, and when the first motor 311 drives the first movable seat 301 to move in the direction of the saw blade for tooth separation, the tooth plate 317 is driven to move synchronously, thereby driving the gear 316 to drive the elliptical block 315 to rotate half a circle, so that the long axis end of the elliptical block 315 contacts the surface of the first push block 313, and drives the first push block 313 to drive the clamping block 312 to move in the direction of the saw blade, thereby synchronously clamping and fixing the saw blade, ensuring the stability of the tooth separation, avoiding the shaking of the rack, and ensuring the quality of the tooth separation.

[0048] The first motor 311 drives the clamping block 312 to move toward the saw blade, and when clamping and fixing the saw blade, it drives the bracket 401 to move synchronously, and under the action of the second spring 406, the brush roller 403 can be tightly attached to the side wall of the saw blade. Therefore, when the bracket 401 approaches the saw blade, it can push the bracket 401 to move backward, the second spring 406 is compressed, and synchronously drives the second connecting rod 409 and the first piston 408 to move backward synchronously, the second one-way valve 411 is turned on, and the lubricating oil in the oil filling cylinder 407 is injected into the hollow part of the rotating shaft 402 through the rotating joint 413, and is injected into the brush roller 403 through the through hole 404, and is rolled onto the surface of the saw blade by the brush roller 403 to complete the lubrication of the saw blade. A thin film can be formed when the saw blade is toothed, reducing the direct metal contact between the tooth block 304 and the teeth, which can effectively reduce the friction coefficient, thereby reducing the wear during the toothing process and protecting the surface quality of the rack.

[0049] The second motor 506 can drive the second rotating wheel 503 to rotate, thereby driving the second movable seat 501 to move forward and backward through the second eccentric shaft 504 and the third connecting rod 505, and pushing the saw blade forward through the push rod 508, so that the saw blade is continuously and automatically divided. When the second motor 506 drives the second movable seat 501 to move forward, it drives the second push block 513 to move forward synchronously, thereby driving the fourth connecting rod 514 and the second piston 512 to move, injecting the air in the cylinder 511 into the nozzle 509, and spraying air to the surface of the saw blade to remove chips through the nozzle 510, so as to prevent the chips remaining on the surface of the saw blade from scratching when it contacts the tooth dividing block 304, thereby ensuring the quality of the saw blade.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
