Description

Technical Field

[0001] The utility model relates to the technical field of slab deburring, in particular to a pressing and boosting mechanism of a slab upper and lower surface deburring machine. Background Art

[0002] After the slab is cut by a flame cutting machine, not only will burrs be generated on the lower surface, but also tiny burr bands will be generated on the upper surface. However, the deburring machine in the prior art is mainly used to remove burrs on the lower surface of the slab. For example, a deburring machine is disclosed in the Chinese utility model patent with authorization announcement number CN2460246Y, which utilizes the slab to move on a transport roller and cooperate with the lower side tool to form relative motion to achieve the burr removal function.

[0003] With the development of technology, deburring machines that can simultaneously remove burrs from the upper and lower surfaces of slabs have also appeared in the prior art. For example, a Chinese invention patent with publication number CN112658225A discloses a toothed deburring machine for the upper and lower surfaces of continuous casting stainless steel slabs. On the basis of the original lower deburring device, an upper deburring device, i.e., an upper scraper, is added. In this way, the device has a deburring action on the upper and lower surfaces of the slab, thereby improving the deburring operation efficiency.

[0004] However, the traditional deburring machine only uses the transmission roller to drive the slab to move, which often makes it difficult to ensure that the dragging force of the slab meets the requirements for removing burrs, especially when the burrs are large and hard. In addition, during the deburring process of the slab, the scraper is required to be close to the surface of the slab to ensure the deburring effect. However, for light slabs, due to the light weight of the slab, the elastic force of the knife seat spring will lift the slab during the deburring process, thereby creating a gap between the transmission roller and the slab, so it is difficult to ensure that the scraper is close to the surface of the slab. Utility Model Content

The first booster device 1 and the second booster device 9 are symmetrically arranged and the power shafts are facing outward. The power shaft ends of each booster device are connected to the upper body 4, so that the first booster device 1 and the second booster device 9 can cooperate with telescope to realize the left and right movement of the upper body 4.

[0032] like Figure 3 As shown, in this embodiment, a lifting slide 501 and a lifting drive device 5 are provided on the upper body 4, wherein the lifting slide 501 is slidably connected to the upper body 4 through a slide rail slider assembly 504, and the lifting slide 501 is driven to lift and lower through the lifting drive device 5.

The lifting drive device 5 can adopt linear drive devices such as cylinders, oil cylinders, and electric push rods as needed.

[0033] like Figure 3 As shown, in this embodiment, a first support arm 502 is provided on one side of the lifting slide 501, and a first pressing wheel 2 is provided at the free end of the first support arm 502, a second support arm 503 is provided on the other side of the lifting slide 501, and a second pressing wheel 8 is provided at the free end of the second support arm 503, a first lifting boost arm 3 is provided on the side of the lifting slide 501 close to the first pressing wheel 2, an upper lifting scraper 6 is provided at the middle part of the lower end of the lifting slide 501, and a second lifting boost arm 7 is provided on the side of the lifting slide 501 close to the second pressing wheel 8. When the utility model is working, the lifting drive device 5 drives the lifting slide 501 to move up and down, and then drives the first pressing wheel 2, the first lifting boost arm 3, the upper lifting scraper 6, the second lifting boost arm 7 and the second pressing wheel 8 to move up and down synchronously, when the lifting slide 501 is lowered into place, the first pressing wheel 2 or the second pressing wheel 8 presses the slab, and then the first lifting boost arm 3, the upper lifting scraper 6, and the second lifting boost arm 7 perform corresponding lifting actions according to processing needs.

[0034] In this embodiment, the lifting slide 501 is provided with an upper scraper lifting drive device for driving the upper lifting scraper 6 to lift and lower. In addition, booster arm lifting drive devices are respectively provided on both sides of the lifting slide 501 to respectively drive the lifting booster arms on the corresponding sides to lift and lower. The upper scraper lifting drive device and the booster arm lifting drive device can use linear drive devices such as air cylinders, oil cylinders, and electric push rods as needed.

[0035] In this embodiment, protective pads can be provided on the outer side of the first pressing wheel 2 and the outer side of the second pressing wheel 8 as needed to contact the slab to avoid scratching the surface of the slab. In addition, rollers are provided at the lower end of the first lifting booster arm 3 and the lower end of the second lifting booster arm 7 to abut against the upper surface of the slab. The rollers can ensure the relative movement of the slab while pressing the slab. The adjacent sides of the lower end of the first lifting booster arm 3 and the lower end of the second lifting booster arm 7 are provided with protective blocks to contact the edge of the slab to avoid damaging the slab.

[0036] like Figure 8 As shown, in this embodiment, sliding support seats 15 are provided on both sides of the upper end of the equipment base 13, and slide rails 11 are provided on the sliding support seats 15. Pulleys 12 are provided on both sides of the lower end of the upper body 4, and the pulleys 12 roll along the corresponding slide rails 11 respectively, thereby realizing the sliding connection between the upper body 4 and the equipment base 13.

[0037] like Figure 8 As shown, a transmission roller 14 and a lower lifting scraper 10 are provided on the equipment base 13, and the upper body 4 is provided above the lower lifting scraper 10. A lower scraper lifting drive device (a linear drive device such as a cylinder or an oil cylinder can be used) is provided on the lower side of the lower lifting scraper 10 to drive its lifting action. The transmission roller 14 and the lower lifting scraper 10 are well-known technologies in the art.

[0038] The working principle of the utility model is:

[0039] The working process of this utility model is:

[0040] Take the processing of slab blank head as an example. Figure 2 As shown, the initial positions of various mechanisms of the utility model are: the lower lifting scraper 10 is in the lowest position and is located below the roller surface of the transmission roller 14, the lifting slide 501 on the upper body 4 is in the highest position, and at the same time drives the first pressure wheel 2, the first lifting booster arm 3, the upper lifting scraper 6, the second lifting booster arm 7 and the second pressure wheel 8 to be in the highest position, the first booster device 1 is in a retracted state, and the second booster device 9 is in an extended state, that is, the upper body 4 is in the rightmost position, and then the slab is driven through the transmission roller 14 into the deburring station.

[0041] like Figure 3As shown, the slab stops moving after reaching the specified position, at which time the lifting drive device 5 drives the lifting slide 501 to descend, and then drives the first pressing wheel 2, the first lifting booster arm 3, the upper lifting scraper 6, the second lifting booster arm 7 and the second pressing wheel 8 to descend at the same time, wherein the first pressing wheel 2 is pressed against the upper surface of the slab, and the second pressing wheel 8 (for subsequent slab tail processing) is suspended, and the lower end rollers of the first lifting booster arm 3 and the lower end rollers of the second lifting booster arm 7 are also pressed against the upper surface of the slab, and then the upper lifting scraper 6 descends and presses against the upper surface of the slab, and at the same time, the lower lifting scraper 10 rises and presses against the lower surface of the slab, and then the transmission roller 14 starts to drive the slab to move in the reverse direction, and during the reverse movement of the slab, the upper lifting scraper 6 removes the burrs on the upper surface of the slab for the first time, and the lower lifting scraper 10 removes the burrs on the lower surface of the slab for the first time.

[0042] In addition, Figures 4-5 As shown, during the reverse movement of the slab, the first lifting and boosting arm 3 is always pressed against the upper surface of the slab, and after the head of the slab passes over the lower end of the second lifting and boosting arm 7, the lower end of the second lifting and boosting arm 7 can continue to drop to a position below the upper surface of the slab, and then when the slab moves in the reverse direction and is in place, the first boosting device 1 cooperates to extend, and the second boosting device 9 cooperates to retract, so that Figures 5-6 As shown, the upper body 4 can be driven to move leftward by the first booster device 1 and the second booster device 9, and in the process of the upper body 4 moving leftward, on the one hand, the upper lifting scraper 6 re-processes and removes the burrs on the upper surface of the slab head as the upper body 4 moves leftward, and on the other hand, since the lower end of the second lifting booster arm 7 is lower than the upper surface of the slab, when the lower end of the second lifting booster arm 7 abuts against the edge of the slab, it can push the slab to continue moving, and in the process of the slab continuing to move to the left, the lower lifting scraper 10 moves relative to the lower surface of the slab head to re-process and remove the burrs on the lower surface of the slab head, thereby ensuring that the burrs on the upper and lower surfaces of the slab are cleanly removed, especially when the burrs are large and hard. At the same time, during this process, the first pressing wheel 2 still maintains a state of pressing the slab to ensure the burr removal effect.

[0043] like Figure 7As shown, when the burrs on the upper and lower surfaces of the head part of the slab are removed (the upper body 4 moves to the left), the lifting slide 501 rises to the highest position again, thereby driving the first pressure wheel 2, the first lifting booster arm 3, the upper lifting scraper 6, the second lifting booster arm 7 and the second pressure wheel 8 to rise to the highest position at the same time to leave enough space for the slab to pass through, and then the slab is driven to the right by the transmission roller until the tail part of the slab enters the deburring station and the tail deburring operation begins. The deburring process is the same as that of the head part, except that the second pressure wheel 8 and the second lifting booster arm 7 are used to press the slab, and the first lifting booster arm 3 is used to descend to a position below the upper surface of the slab to realize the function of pushing the slab to move.
