This invention provides a saw blade inner corner rounding grinding device, comprising a work platform, a mounting frame, a grinding device, a tooth-shifting assembly, a movable clamping plate, and a fixed clamping plate. A feeding hydraulic rod is mounted on the mounting frame, with its movable end connected to a bearing block. A lifting block is slidably mounted on the bearing block, and a mounting rod is mounted on the lifting block. The tooth-shifting assembly is slidably mounted on the mounting frame. When the saw blade is installed, it is positioned with the tooth-shifting assembly. Then, the feeding hydraulic rod moves the bearing block to the processing position. The movable and fixed clamping plates clamp the saw blade. The grinding device drives the grinding wheel to descend and rotate, grinding the inner corner rounding of the saw blade. After grinding one tooth, the tooth-shifting assembly drives the saw blade to rotate at a set angle to grind the next tooth. All saw blade teeth can be ground at once, making the operation simple and highly efficient.

This invention discloses a tooth grinding machine for wide-width band saw blade processing, including limiting plates and a workpiece processing mechanism. A saw blade body portion is inserted between two limiting plates, and each limiting plate has an inclined hole on its side. The inclined hole faces opposite directions to the tooth grooves on the saw blade body. The bottom end of the limiting plate extends into the material collection hopper. The advantages of this invention are: during the feeding process, the abrasive is also driven to rotate by the processing actuator, which can fully fill the gap formed between the annular surface in the middle of the processing actuator and the inner wall of the tooth groove, thus achieving the effect of abrasive grinding the inner wall of the tooth groove. The abrasive is fed in a state of simultaneous movement and rotation, resulting in a finer and smoother grinding surface; it fully utilizes the abrasive, reducing the number of times it needs to be added; and it can automatically adjust and position the tooth grooves on the saw blade body, allowing for rapid adjustment to the grinding state.

This application relates to the field of sawing technology and discloses a tooth groove grinding machine for band saw blade production, including a support base. A support plate is slidably mounted on the top of the support base, and a support plate for supporting the band saw blade is fixedly mounted on the top of the support plate. During the movement of the support plate and the band saw blade, the flow of hydraulic medium in the rodless chamber of the cylinder and the auxiliary delivery pipe drives the push plate to move continuously to compensate for missing displacement when the auxiliary cam wears. This ensures that the corresponding tooth grooves on the band saw blade can be properly ground by the grinding wheel, reducing the probability of reduced grinding depth due to tooth groove position deviation. At the same time, under the action of the auxiliary tension spring and the spring force, the machine only needs to be stopped to replace the band saw blade and repair or replace the auxiliary cam after the current band saw blade is ground. This ensures the continuity of tooth groove grinding while maintaining the quality of band saw blade grinding, without the need to stop the machine immediately to replace the auxiliary cam, thus improving grinding efficiency.

This invention discloses an end-grinding machine for a wide-width band saw blade production line, belonging to the field of saw blade grinding technology. The grinding machine includes a grinding machine body, a saw blade body, a grinding wheel body, and a machine cover. Grinding wheel bodies are located on the left and right sides of the grinding machine body, and the machine cover covers the outer sides. A clamping assembly is located on the front of the machine cover, and a protective cover is movably connected to its upper end.

The process mainly comprises the following steps: first head welding; second head welding; adjusting the deflection angle of a laser beam by a galvanometer so that the laser beam irradiates the weld and the heat affected zone of the previous head which has been welded and is in a natural cooling state, and then performing tempering scanning with low energy density so that the tempering treatment is completed; at the same time, the head which has been welded is naturally cooled; the operation is circular until the last head is welded; and the last head is tempered. In the laser welding process, the tempering scanning task of the previous head is alternately performed by the galvanometer deflection while the current head is being welded and is being cooled ， Thus, the hardened structure of the weld is eliminated, the toughness and fatigue strength of the weld of the head are improved, the welding time is saved, and the overall machining efficiency is improved. The application is mainly used for the laser welding of saw blade heads.

The invention relates to a method and device for controlling the feed rate (v) of a saw blade which is provided with teeth and rotates about a centre point relative to a workpiece during a machining process.
