Description

Technical Field

[0001] The invention belongs to the technical field of wood processing, and in particular relates to a horizontal band saw machine. Background Art

[0002] A bandsaw is a modern piece of mechanical processing equipment used to cut logs, rough cuts, or other materials. It primarily consists of a saw, a saw wheel, and a slide. The saw is a ring-shaped, endless bandsaw blade with side teeth. The blade is wound around two saw wheels and driven by a motor for unidirectional linear motion. The slide clamps the material and moves linearly along the slide, cutting it to meet specific process requirements. Furthermore, because bandsaws can accommodate different types of blades and are driven by a motor, they can automate cutting. The thin blades used minimize the kerf width, conserving wood, are simple to operate, and offer high productivity. These bandsaws have promising market prospects and have begun to replace circular saws as the preferred woodworking equipment.

[0003] Existing band saws can only perform flat surface processing. For example, Chinese patent document CN206405525U (CN201720041397.8) discloses a CNC worktable structure for a band saw. The worktable can only move longitudinally and laterally relative to the band saw frame and cannot be used for curved surface processing, especially curved surface processing of larger workpieces. Summary of the Invention

[0004] The main purpose of the present invention is to provide a horizontal band saw machine. The present invention utilizes the mutual cooperation between the swinging teeth and the outer ring of the arc rack to control the rotation of the bracket around the sawing point of the circular band saw. In addition, the longitudinal platform is used to control the feed amount of the workpiece in the front and rear directions, and the transverse platform is used to control the feed amount of the workpiece in the left and right directions. The clamping mechanism clamps the workpiece and slides it on the processing surface, thereby realizing the curved surface processing of larger-sized workpieces; and the band saw working section of the circular band saw can cooperate with the transverse platform with a small gap to realize the sawing of thinner plates.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: A horizontal band saw machine comprises a band saw machine body, a rotating support plate and a moving platform; The band saw machine body includes a base, a bracket, a swing motor, a driving wheel, a driven wheel, an annular band saw and a driving motor, the base is connected to a rotating support plate through a rotating shaft, the rotating support plate is provided with an arc rack, the bracket and the swing motor are fixedly arranged on the base, and the swing motor is connected to the outer ring of the arc rack through a swing tooth; The driving wheel and the driven wheel are rotatably arranged on the bracket, the driving wheel is located below the driven wheel, the annular band saw is sleeved on the driving wheel and the driven wheel, the driving motor is in transmission connection with the driving wheel, a band saw working section is provided on the bracket, the annular band saw of the band saw working section is vertically arranged, and the rotating shaft is located directly below the band saw working section; The mobile platform includes a support frame, a longitudinal platform, a transverse platform and a processing surface, the rotating support plate is fixedly connected to the front of the support frame, the longitudinal platform can be slid forward and backward and is arranged on the transverse platform, the transverse platform can be slid left and right and is arranged on the support frame, and the processing surface is arranged on the transverse platform; A clamping mechanism is provided on the longitudinal platform, and the clamping mechanism includes a movable clamp and a fixed clamp arranged opposite to each other in the upper and lower directions. The processing surface is protruding with multiple rows of universal balls. The clamping surface of the fixed clamp is flush with the top of the universal ball. A ruler is provided on the right side of the processing surface.

[0006] The present invention preferably further includes a heavy-duty bull's eye mounted on the bracket, wherein the rotating support plate is provided with two or more curved slideways, the heavy-duty bull's eye being rollingly connected to the curved slideways, and the curved slideways being coaxially arranged with the rotating shaft. Since the center of gravity of the band saw body is located on the bracket in front of the rotating shaft, two heavy-duty universal ball pairs are installed to provide auxiliary support for the bracket, thereby reducing deformation of the bracket and ensuring stability of the bracket during rotation.

[0007] Preferably, the present invention further comprises a guide roller, wherein the guide roller is fixed on the base and is in rolling engagement with the inner ring of the arc rack; The guide roller, swing tooth, and rotating shaft are located on the same straight line. Since the arc rack is eccentrically arranged to the left of the rotating shaft, and the center of gravity of the band saw body is located on the bracket in front of the rotating shaft, the arc rack is constantly subjected to rightward force during the rotation of the band saw body. By providing the guide roller, the guide roller, swing tooth, and rotating shaft are located on the same straight line, thereby reducing the force on the arc rack and ensuring stable operation of the band saw body.

[0008] Preferably, the drive motor and the bracket are respectively arranged on the front and rear sides of the rotating shaft, the drive motor and the swing motor are respectively arranged on the left and right sides of the rotating shaft, and the drive motor is connected to the driving wheel through a belt or a transmission chain; The drive motor is located below the support frame. The drive motor and the support frame are respectively arranged on the front and rear sides of the rotating shaft, and the drive motor and the swing motor are respectively arranged on the left and right sides of the rotating shaft, thereby reducing the eccentricity of the band saw body. While increasing the radius of the arc rack to provide greater rotational torque, the band saw body is made more stable during rotary sawing.

[0009] The present invention preferably further includes an annular connecting rod fixedly mounted on the rotating support plate, with both ends of the connecting rod fixedly connected to the support frame. The connecting rod is used to connect the rotating support plate and the support frame together, further improving the stability of the band saw body during the rotating processing process.

[0010] Preferably, the present invention further comprises a baffle and a stopper, wherein the two baffles are fixed on the lower end surface of the base, and the two stoppers are fixed on the upper end surface of the rotating support plate; With the rotation axis as the center, the angle formed between the two baffles and the rotation axis corresponds to the rotation angle of the arc rack. The baffles and the stop block limit the rotation angle of the bracket to avoid collision between the band saw machine body and the mobile platform.

[0011] Preferably, the transverse platform includes a workbench base and a longitudinal support beam, the workbench base is slidably arranged on the support frame, the longitudinal support beams are arranged on the workbench base at intervals from left to right, and the processing surface includes a plurality of slides, the slides are arranged between two longitudinal support beams, and a clamping mechanism is arranged in each slide; The processing surface is mounted on the longitudinal support beam, and the universal ball is detachably mounted on the upper end surface of the longitudinal support beam; The longitudinal platform includes a transverse support beam, which is slidably mounted on the workbench base. The transverse support beam is located between the longitudinal support beam and the workbench base, and the clamping mechanism is detachably mounted above the transverse support beam. The clamping mechanism is mounted on the transverse support beam. When the transverse support beam slides back and forth, the clamping mechanism clamps the workpiece and moves it back and forth along the slideway, controlling the amount of sawing. Under the action of the universal ball, the workpiece slides on the processing surface, effectively reducing the resistance to workpiece feeding and facilitating material loading. The processing surface is mounted on the longitudinal support beam and only slides left and right with the workbench base. That is, the front-to-back distance between the processing surface and the annular band saw is fixed, and the processing surface can be set close to the annular band saw, thereby improving the stability of the workpiece during processing.

[0012] Preferably, the bracket is provided with an auxiliary workbench, the auxiliary workbench is arranged flush with the processing surface, and a universal ball is provided on the upper end surface of the auxiliary workbench; The auxiliary workbench and the processing surface are located at the front and rear sides of the circular band saw respectively. The auxiliary workbench supports the front end of the workpiece to ensure stable sawing of the workpiece on the circular band saw, and the universal ball on the end surface of the auxiliary workbench reduces the resistance during the sawing process.

[0013] Preferably, the present invention further comprises an auxiliary pressing plate and a lifting drive device, wherein the lifting drive device is arranged on the bracket, and the auxiliary pressing plate is arranged parallel to the processing surface and higher than the processing surface; The lower end surface of the auxiliary pressure plate is equipped with a universal ball, and the lifting drive device is used to control the lifting and lowering of the auxiliary pressure plate. The auxiliary pressure plate cooperates with the auxiliary workbench or processing surface to provide auxiliary pressure on the workpiece, ensuring sawing stability during processing and improving workpiece processing quality.

[0014] Preferably, the band saw machine body further comprises an upper guide roller assembly, a lower guide roller assembly and a lifting device, wherein the upper guide roller assembly and the lower guide roller assembly are located on the upper and lower sides of the band saw working section; The upper guide roller assembly includes a first support seat and a first clamping bearing, the first support seat is movably arranged on the bracket, and the first clamping bearing is rotatably arranged on the first support seat, two first clamping bearings are located on both sides of the annular band saw, and one first clamping bearing is located on the back of the annular band saw; The lifting device is fixed on the bracket and is used to drive the first support seat to move up and down; The lower guide roller assembly includes a second support base and a second clamping bearing. The second support base is fixed to the bracket, with two second clamping bearings located on either side of the circular band saw and one second clamping bearing located on the back of the circular band saw. The upper guide roller assembly limits the position of the circular band saw above the cutting point, while the lower guide roller assembly limits the position of the circular band saw below the cutting point. This reduces vibration during operation, improves workpiece processing quality, and reduces wear and tear on the circular band saw. Furthermore, a lifting device drives the first support base up and down to accommodate workpieces of varying thicknesses.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention connects the base of the band saw machine body to the rotating support plate via a rotating shaft, sets an arc rack on the rotating support plate, fixes the bracket and the swing motor on the base, and connects the swing teeth to the outer ring of the arc rack, thereby realizing the rotation operation of the band saw machine body. Since the rotating shaft is located directly below the working section of the band saw, it can ensure rotation around the sawing point of the annular band saw, and can more flexibly adjust the sawing direction. The present invention uses the longitudinal platform of the mobile platform to control the forward and backward movement of the workpiece, and uses the transverse platform to control the left and right movement of the workpiece. By coordinating with the rotational movement of the band saw machine body, the curved surface processing of the workpiece is realized. In addition, by increasing the radius of the arc rack, it is possible to provide a greater rotational torque when the size of the band saw machine body is compact.

[0016] The present invention uses the processing surface to support the workpiece. Since the clamping surface of the clamping mechanism fixing jaws is flush with the top of the universal ball, and a ruler is provided on the right side of the processing surface, rectangular plates can be quickly loaded and positioned. Moreover, the workpiece can be processed by simply fixing the edge of the workpiece with the clamping mechanism and providing a propulsion force. The invention is suitable for processing workpieces of larger sizes. BRIEF DESCRIPTION OF THE DRAWINGS
