Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a section steel cutting device. Background Art

[0002] Steel is a strip steel with a certain cross-sectional shape and size. It is one of the four major types of steel (plate, tube, profile, wire). According to the cross-sectional shape, steel is divided into simple cross-sectional steel and complex cross-sectional steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, curved steel, etc.

[0003] The steel section needs to have different specifications and sizes when it leaves the factory, and the length of the steel section is generally 6 meters, 9 meters or 12 meters. Therefore, the steel section needs to be cut after it is produced so that the length can reach the factory standard. When cutting, the steel section is conveyed forward by the conveyor. A baffle is set on the conveyor. The distance between the baffle and the cutting saw is the length specification of the steel section. The baffle is connected to the piston rod of the hydraulic cylinder. The hydraulic cylinder drives the baffle to rise or fall. When the baffle rises, the baffle is located above the conveyor. When one end of the steel section contacts the baffle, the baffle blocks the steel section, and the cutting saw cuts it to obtain the corresponding product. After the cutting is completed, the baffle falls, and the steel section continues to be conveyed along the conveyor. However, the baffle is generally fixedly connected to the piston rod of the hydraulic cylinder. The hydraulic cylinder drives the baffle to rise and fall, and when the steel section contacts the baffle, a certain impact vibration will be generated, and the vibration will be transmitted to the hydraulic cylinder. After long-term use, the hydraulic cylinder will be damaged, resulting in oil leakage or piston rod bending, and it is necessary to shut down for maintenance and replacement, which reduces production efficiency.

[0030] The positioning assembly includes a positioning frame 4, a baffle 5, a reset spring 6 and a pressing member 7. The positioning frame 4 is fixedly arranged on the frame of the positioning conveyor 3. The positioning frame 4 is a rectangular frame structure, including a top plate, a bottom plate and two side walls. The positioning frame 4 is vertically fixedly arranged on the frame of the positioning conveyor 3. The baffle 5 is vertically slidably arranged in the positioning frame 4. The distance between the baffle 5 and the cutting saw 2 is the cutting length of the steel section. The reset spring 6 is arranged at the lower end of the baffle 5. One end of the reset spring 6 It is fixedly connected to the lower end of the baffle 5, and the other end is fixedly connected to the bottom of the positioning frame 4. The return spring 6 can lift the baffle 5 under normal conditions, so that the baffle 5 is above the positioning conveyor 3, and has a blocking effect on the steel sections on the positioning conveyor 3. The clamping member 7 is fixedly arranged on the top of the positioning frame 4, and the movable end of the clamping member 7 abuts against the upper end of the baffle 5. The movable end of the clamping member 7 can press the baffle 5 down after extending, so that the baffle 5 slides down to the bottom of the positioning conveyor 3, so that the steel sections can be normally transported on the positioning conveyor 3.

[0031] In the present invention, the steel to be cut is transported along the conveyor 1, and the steel is transported to the positioning conveyor 3 after passing through the cutting saw 2. At this time, the movable end of the clamping member 7 is in a retracted state, and the baffle 5 is located above the positioning conveyor 3 under the action of the return spring 6. The steel continues to be transported along the positioning conveyor 3 until the steel contacts the baffle 5. During the contact process, the steel will collide with the baffle 5, but at this time, the baffle 5 is not in direct contact with the movable end of the clamping member 7, so the vibration will not be transmitted to the clamping member 7, avoiding damage to the clamping member 7; when the steel contacts the baffle 5, The positioning conveyor 3 and the transmission conveyor 1 stop conveying, at which time the clamping assembly clamps the steel section and fixes it, and the cutting saw 2 cuts the steel section; after the cutting is completed, the clamping assembly is released, at which time the movable end of the clamping member 7 extends out, pressing down the baffle 5, so that the baffle 5 slides to the bottom of the positioning conveyor 3, and the positioning conveyor 3 is turned on to transport the cut steel section to the next workstation, and then the movable end of the clamping member 7 retracts, and the baffle 5 rises under the action of the reset spring 6, and the transmission conveyor 1 is turned on to continue to transport the steel section to be cut. The above steps are repeated continuously to continuously cut the steel section.

[0032] It should be noted that the clamping member 7 is a type of air cylinder, hydraulic cylinder or electric push rod. In this embodiment, a hydraulic cylinder is used, and the cylinder barrel of the hydraulic cylinder is fixedly arranged at the upper end of the positioning frame 4. The piston rod of the hydraulic cylinder is in contact with the baffle 5. After the piston rod is extended, it can push the baffle 5 to slide down.

[0033] Furthermore, a slide groove 8 is provided on the side wall of the positioning frame 4, and the slide groove 8 passes through the side wall of the positioning frame 4. A limit plate 9 is fixedly arranged on the baffle 5, and the limit plate 9 is slidably arranged in the slide groove 8. The limit plate 9 can limit the baffle 5 so that the baffle 5 can move in the vertical direction to avoid the baffle 5 from being tilted.

[0034] In another embodiment, the left and right ends of the baffle plate 5 are slidably disposed in the slide groove 8 , so that the baffle plate 5 can slide up and down along the slide groove 8 , thereby improving the stability of the baffle plate 5 .

[0035] Furthermore, the limit plate 9 is located below the positioning conveyor 3, and the limit plate 9 is arranged at the lower end of the baffle 5. One end of the limit plate 9 away from the baffle 5 extends to the outside of the positioning frame 4. After the baffle 5 is raised, the limit plate 9 abuts against the positioning conveyor 3, which can limit the baffle 5 and prevent the baffle 5 from rising too high.

[0036] Furthermore, a connecting plate 10 is fixedly provided at the upper end of the baffle 5, and the connecting plate 10 is slidably set in the slide groove 8. One end of the connecting plate 10 away from the baffle 5 extends to the outside of the positioning frame 4. The connecting plate 10 is located above the positioning conveyor 3, and the movable end of the clamping member 7 abuts against the connecting plate 10. When the clamping member 7 drives the baffle 5 to slide down, the movable end of the clamping member 7 extends out and presses the connecting plate 10 downward, driving the baffle 5 to slide down, so that the steel section can continue to be transported on the positioning conveyor 3.

[0037] Furthermore, the connecting plate 10 is an "L"-shaped structure, including a vertical portion and a horizontal portion, the vertical portion is fixedly arranged at the upper end of the connecting plate 10, and the horizontal portion is fixedly arranged at the upper end of the vertical portion, the vertical portion is arranged vertically, and the horizontal portion is arranged horizontally, and the movable end of the clamping member 7 abuts against the horizontal portion of the connecting plate 10, so that after the clamping member 7 presses down the baffle 5, the baffle 5 can be completely located under the positioning conveyor 3 to avoid obstruction to the movement of the steel section.

[0038] It should be noted that there are two connecting plates 10, which are respectively located at the left and right ends of the baffle 5, and there are two clamping members 7, which are respectively located at the left and right ends of the positioning frame 4.

[0041] Furthermore, a clamping plate 15 is horizontally slidable inside the fixed cover 11. The clamping plate 15 can clamp and fix the side of the steel section, and the function of the clamping plate 12 can clamp the steel section more firmly to avoid the steel section shaking during the cutting process. A second clamping piece 16 is fixedly provided on the side plate of the fixed cover 11, and the movable end of the second clamping piece 16 is fixedly connected to the clamping plate 15.

[0042] Furthermore, a second guide rod 17 is fixedly provided on the clamping plate 15 , and the second guide rod 17 is slidably provided on the side plate of the fixed cover 11 . The second guide rod 17 can prevent the clamping plate 15 from shaking, and the clamping of the steel section is more stable.

[0043] It should be noted that the first clamping member 13 and the second clamping member 16 are both hydraulic cylinders, driving the pressing plate 12 and the clamping plate 15 to move in the fixing cover 11 .

[0044] Furthermore, the cutting saw 2 is a band saw machine, and any existing band saw machine on the market can be used.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
