Description

Technical Field

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

[0002] Vertical band saw is a kind of sawing equipment widely used in the industrial field. Its main features and functions are as follows: Vertical band saw drives the saw blade to rotate through the motor. The saw blade is usually composed of a band-shaped cutting tool, so it is also called a band saw. Wood or other materials are placed on the workbench, and the saw blade is moved up and down along the guide rail by manual or automatic control to achieve the cutting of the material. The saw blade is easy to deviate when it contacts the sawed object during the cutting process. The saw blade without guidance and poor stability may be subjected to excessive stress during the cutting process, causing the saw blade to break or be damaged.

[0003] In a Chinese patent with publication number CN117900560A, an automatic metal cutting machine is mentioned. The specification discloses that during the vertical cutting process of a metal band saw blade, the blade is prone to vibration and deviation, which directly affects the cutting accuracy and the quality of the workpiece. In addition, a saw blade with poor stability may be subjected to excessive stress during the cutting process, causing the saw blade to break or be damaged, which not only increases the frequency and cost of replacing the saw blade, but also may pose a safety threat to the operator due to the sudden breakage of the saw blade;

[0046] In this embodiment, taking the first guide wheel 202 as an example, when the placement frame 208 is installed inside the first guide wheel 202, the placement frame 208 is inserted into the concave hole 207. During the sliding process of the placement frame 208, it will contact the first magnetic block 211. The placement frame 208 is made of iron material. Until the placement frame 208 is completely merged with the first guide wheel 202, at this time, the sponge block 210 on the storage box 209 and the circular hole 213 on the first guide wheel 202 are on the same horizontal line, and then the catheter 212 is inserted into the circular hole 213 until the catheter 212 squeezes the sponge block 210, and the sponge block 210 is inserted into the storage box 209 through the leakage hole on the storage box 209. The position of the catheter 212 is at the leakage hole and is also stabilized.

The storage box 209 is filled with lubricating liquid, and the sponge block 210 plays a role in preventing the lubricating liquid in the storage box 209 from flowing out.

[0047] refer to Figure 3 , Figure 4 , Figure 7 and Fig. 9 As shown, the auxiliary mechanism 4 can facilitate the limiting of the sawed object and can be used in conjunction with the guide mechanism 2 and the adjustment mechanism 3. The auxiliary mechanism 4 includes a second spring 401 fixedly connected to the end face of the partition 101, the top of the second spring 401 is fixedly connected to a connecting plate 402, one end of the connecting plate 402 is fixedly connected to a support frame 403, the surface of the support frame 403 is fixedly connected to a long column 404 and a second magnetic block 405, the end face of the long column 404 is provided with a socket 406, the arc surface of the cylinder 313 is fixedly connected to a gear 407, the tooth surface of the gear 407 is meshed with a rack 408, the bottom end of the rack 408 is fixedly connected to a slide rod 409, the arc surface of the slide rod 409 is inserted with a cylinder 410, the cylinder 410 is fixedly connected to the end face of the partition 101, and the side wall of the rack 408 is fixedly connected to a fixing rod 411 that cooperates with the socket 406.

[0048] In this embodiment, the initial state of the second spring 401 is a normal state, that is, Figure 4In the middle state, the support frame 403 can limit the object being sawed, ensuring that the object being sawed can move in a straight line when moving, and can also block the lubricating liquid thrown out by the second guide wheel 206. When the saw belt 106 breaks, the support frame 403 can support the adjusting rod 303 after changing its position, preventing the bracket 105 from lowering its height and resting on the adjusting rod 303, causing the adjusting rod 303 to rotate.

[0049] The cross-sectional shape of the second magnetic block 405 is L-shaped, the cross-sectional shape of the fixing rod 411 is L-shaped, and the size of the fixing rod 411 is matched with the size of the insertion hole 406 .

[0050] The second magnetic block 405 can be adsorbed onto the L-shaped plate 204 , and the fixing rod 411 cooperates with the insertion hole 406 to stabilize the elastic force of the second spring 401 .

[0051] A groove 412 is formed on the surface of the support frame 403 , an extension plate 413 is slidably connected to the inner wall of the groove 412 , a support plate 414 is fixedly connected to the side wall of the extension plate 413 , and a screw 415 is threadedly connected to the surface of the support plate 414 .

[0052] Both ends of the placement frame 208 are arc-shaped. The two placement frames 208 can be combined with the first guide wheel 202 and the second guide wheel 206 to form two complete circles. A depression is provided on one side of the support frame 403, and the depression is adapted to the arc surface of the adjustment rod 303.

[0053] The working principle of the present invention is as follows: in the initial state, the second spring 401 is not deformed. At this time, under the action of the second spring 401, the position of the support frame 403 can be adjusted at will. Figure 4 Adjust the position to Figure 3The second spring 401 is in a twisted and compressed state. At this time, the support frame 403 is supported to stabilize it, and then the position of the adjusting rod 303 is adjusted. At this time, the position of the arc surface of the adjusting rod 303 is on the upper and lower sides. Then, the handle 305 is turned to drive the adjusting rod 303 to rotate. Since the handle 305 is made of iron material, the electromagnet 308 is energized, and the handle 305 will be adsorbed on the electromagnet 308, so that the position of the arc surface of the adjusting rod 303 changes to the left and right sides. When the adjusting rod 303 rotates, the gear 407 will rotate, and the rack 408 will be driven by the gear When the transmission 407 moves downward, the slide bar 409 will be inserted downward into the long socket 406 of the long column 404, so as to stabilize the support frame 403. At the same time, when the adjusting rod 303 rotates, the torsion spring 304 is in a torsion state. When the adjusting rod 303 rotates, the long rod 302 will wrap around the connecting rope 310. The tightening of the connecting rope 310 will drive the sliding frame 205 to move. At this time, the second guide wheel 206 will move away from the first guide wheel 202. The initial position of the saw belt 106 is between the first guide wheel 202 and the second guide wheel 2 06, under the action of the first spring 312, the saw belt 106 will be tightly clamped. At this time, the movement distance of the sliding frame 205 is only a little. To ensure that the arc surface of the first guide wheel 202 and the second guide wheel 206 can still contact with the saw belt 106, the first spring 312 will be compressed due to the movement of the sliding frame 205. When sawing a wooden board, the wooden board can keep moving in a straight line along one side of the support frame 403 to ensure the sawing effect. If it is necessary to adjust the length of the support frame 403, the support plate 414 can be pulled to move the extension plate 413 out of the groove 412. , screw the screw 415, which is driven by the thread and squeezed onto the support frame 403, so as to stabilize the position of the extension plate 413. When the saw belt 106 is driven, it will contact the first guide wheel 202 and the second guide wheel 206, so that they both rotate. Under the action of centrifugal force, the lubricating liquid in the storage box 209 inside the first guide wheel 202 and the second guide wheel 206 will be thrown out from the guide tube 212 and leak out from the circular hole 213 to contact the saw belt 106, so as to achieve the effect of lubricating the saw belt 106, and reduce the friction and heat of the saw belt 106;

[0054] When the saw band 106 breaks, the electromagnet 308 will be powered off and the magnetic force will disappear. At this time, the handle 305 will rebound under the action of the torsion spring 304, so the adjusting rod 303 will rebound, and the position of the arc surface of the adjusting rod 303 will change from the two sides to the top and bottom. The bracket 105 will move downward due to the rotation of the adjusting rod 303, that is, the sliding tube 3061 will slide downward along the arc surface of the vertical rod 306. When the adjusting rod 303 rotates, the connecting rope 310 will be released, and under the rebound of the first spring 312, the sliding frame 205 drives the second guide wheel 206 to move slightly in the direction close to the first guide wheel 202 to clamp the saw blade and try to avoid the saw blade from splashing when it breaks. At the same time, the gear 407 will also rotate, driving the rack 408 to move upward until the slide bar 409 moves out of the socket 406. At this time, the second spring 401 loses its stability and rebounds immediately, and the support frame 403 quickly returns to its original position. Figure 4 Since the L-shaped plate 204 is made of iron material, the second magnetic block 405 will be adsorbed on the L-shaped plate 204, and the support frame 403 plays a role of supporting the bracket 105.
