Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As shown in the figure, a horizontal band saw machine for sawing flange rings includes a frame 1, on which a feeding mechanism 3, a band saw mechanism 2 and a unloading mechanism 4 are sequentially arranged, so that the feeding mechanism 3 and the unloading mechanism 4 are respectively located on both sides of the band saw mechanism 2, the feeding mechanism 3 is used to transport materials to the band saw mechanism 2, the band saw mechanism 2 is used to saw the materials, and the unloading mechanism 4 is used to position the materials being transported and unload the flange ring after sawing.

[0023] The structure of the band saw mechanism 2 is prior art and will not be described in detail here.

[0024] Among them, the structure of the unloading mechanism 4 is as follows: the unloading mechanism 4 includes an unloading turning disk 41, an unloading cylinder 42 and an unloading conveyor belt 43, the lower end of the unloading turning disk 41 is hinged on the frame 1 and is upright on one side of the band saw mechanism 2, and the lower end of the unloading turning disk 41 facing the band saw mechanism 2 is formed with an arc-shaped positioning portion 411, the two conveyor belts are arranged on the frame 1 and are located on one side of the unloading turning disk 41, the unloading cylinder 42 is hinged on the frame 1 and the output shaft of the unloading cylinder 42 is hinged on the unloading turning disk 41, the unloading turning disk 41 is provided with two clearance grooves 412 which can be aligned with the two unloading conveyor belts 43 respectively, the clearance grooves 412 pass through the unloading turning disk 41 in the direction away from the positioning portion 411, and the unloading cylinder 42 can drive the unloading turning disk 41 to swing so that the unloading conveyor belt 43 passes through the clearance grooves 412.

[0025] Among them, the structure of the feeding mechanism 3 is as follows: the feeding mechanism 3 includes a conveying roller 31 and a pushing plate 32, a plurality of the conveying rollers 31 are arranged on the frame 1 to rotate obliquely to form two symmetrical rows, and a feeding channel 33 aligned with the unloading turning plate 41 is formed between the two rows of conveying rollers 31, and the pushing plate 32 can be slidably arranged on the frame 1 along the length direction of the feeding channel 33 and is located between the two rows of conveying rollers 31.

[0026] Specifically, the push plate 32 is slidably arranged on the frame 1: the frame 1 is provided with two support rods 34 located below the feeding channel 33, the lower end of the push plate 32 is passed through the two support rods 34, and the frame 1 is rotatably provided with a transmission screw 35 which is screwed on the push plate 32 and is transmission-connected to a motor 36 arranged on the frame 1.

[0027] The material to be sawed is placed on two rows of conveying rollers 31 in the feeding channel 33 so that the end of the material is aligned with the material unloading turning disk 41. At this time, the unloading plate is located on the side of the end of the material away from the unloading turning disk 41. Then, the motor 36 drives the transmission screw 35 to rotate. The transmission screw 35 drives the push plate 32 to move toward the material on the support rod 34 through the threaded cooperation with the push plate 32 and abuts against the end of the material, thereby pushing the material to move toward the unloading turning disk 41 on the conveying roller 31. After the material passes under the band saw of the band saw mechanism 2, its end abuts against the unloading turning disk 41 erected on one side of the band saw mechanism 2. The unloading turning disk 41 cooperates with the push plate 32 to clamp and fix the material, and the positioning portion 411 is located below the end of the material abutting against the unloading turning disk 41 and fits the surrounding side of the material, which plays a role in positioning and supporting the end of the material. Then, the band saw mechanism 2 drives the band saw to move downward to saw the material. After the sawing is completed, the flange formed The ring is supported by the positioning portion 411 and maintained on the unloading turning disk 41, and then the unloading cylinder 42 drives the unloading turning disk 41 to swing with the flange ring toward the unloading conveyor belt 43. When the unloading turning disk 41 swings to a horizontal position, the unloading conveyor belt 43 passes through the make way groove 412 and contacts the flange ring placed on the unloading turning disk 41, and the unloading conveyor belt 43 drives the flange ring to leave the unloading turning disk 41 through friction, so that the flange ring falls completely onto the unloading conveyor belt 43 and transports the unloading conveyor belt 43 backward to realize unloading. Then, the unloading cylinder 42 drives the unloading turning disk 41 to swing back to an upright state, and the push plate 32 continues to push the material toward the unloading turning disk 41 for the next sawing operation. Through the above structure and method, it is only necessary to place the material on the conveying roller 31, and the material conveying and loading and the unloading of the flange ring after sawing can be carried out automatically and continuously, thereby reducing the manual participation in the sawing operation, saving manpower, and improving the efficiency of the sawing operation.

[0028] Preferably, the blanking mechanism 4 further includes a material pushing component, which includes a lifting plate 44 and a material pushing plate 45. The lifting plate 44 is longitudinally slidably arranged on the frame 1 above the two blanking conveyor belts 43, and the lifting plate 44 is fixedly connected to the output shaft of a lifting cylinder 46 arranged on the frame 1. A material pushing cylinder 47 with an output shaft facing the blanking turntable 41 is arranged on the lifting plate 44, and the material pushing plate 45 is fixedly connected to the output shaft of the material pushing cylinder 47. When the blanking cylinder 42 drives the blanking turntable 41 to swing so that the blanking conveyor belt 43 contacts the flange ring placed on the blanking turntable 41, the material pushing cylinder 47 drives the material pushing plate 45 to move towards the flange ring until it is above the inner hole of the flange ring. Then, the lifting cylinder 46 drives the lifting plate 44, driving the material pushing cylinder 47 and the material pushing plate 45 to move downward, so that the material pushing plate 45 moves into the inner hole of the flange ring. Then, the material pushing cylinder 47 drives the material pushing plate 45 to move in the conveying direction of the blanking conveyor belt 43, making the material pushing plate 45 abut against the inner hole wall of the flange ring, so that the material pushing plate 45 pulls the flange ring to move in the conveying direction of the blanking conveyor belt 43, ensuring that the sawn flange ring can completely leave the blanking turntable 41 and fall onto the blanking conveyor belt 43 to achieve blanking.

[0029] Further, a clamping mechanism 5 is arranged on the frame 1 between the feeding mechanism 3 and the sawing mechanism. The clamping mechanism 5 is used to clamp and fix the material during sawing. Specifically, the structure of the clamping mechanism 5: The clamping mechanism 5 includes a mounting frame 51, clamping plates 52, and clamping cylinders 53. The mounting frame 51 is fixedly arranged on the frame 1, and the mounting frame 51 has a feeding port 511 aligned with the feeding channel 33. The two clamping cylinders 53 are symmetrically arranged on the mounting frame 51, and the output shafts of the clamping cylinders 53 extend into the feeding port 511. The two clamping plates 52 are respectively fixedly connected to the output shafts of the two clamping cylinders 53.

[0030] In the above preferred embodiment, when the feeding mechanism 3 conveys the material placed on the conveying roller 31 towards the blanking turntable 41, the material passes through the feeding port 511 and passes between the two clamping plates 52, and then passes under the band saw of the band saw mechanism 2 and abuts against the blanking turntable 41. While the band saw mechanism 2 saws the material, the two clamping cylinders 53 respectively drive the two clamping plates 52 to move towards the material and tightly abut against the peripheral side surface of the material, clamping and fixing the material, strengthening the stability of the material during sawing by the band saw mechanism 2, thereby ensuring the quality of sawing.

[0031] Preferably, the clamping plate 52 is arc-shaped and an anti-slip cushion layer 521 is arranged on the inner side surface of the clamping plate 52. The arc-shaped clamping plate 52 can better match and fit with the peripheral side surface of the material, strengthening the clamping and fixing effect of the clamping plate 52 on the material. The anti-slip cushion layer 521 further strengthens the clamping and fixing effect on the material by increasing the friction between the clamping plate 52 and the material. Moreover, the anti-slip cushion layer 521 made of flexible material can play a certain role in buffering and shock absorption when the band saw mechanism 2 saws the material.

[0032] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
