Description

Technical Field

[0001] The present invention relates to the technical field of abrasive wheel saws, and particularly to a Brown abrasive wheel saw. Background Art

[0002] The Brown abrasive wheel saw is a device used for segmenting and sizing sawing of continuous rolling steel, and is widely used in the special steel industry. A set of hydraulic-driven vertical clamping devices are respectively arranged at the inlet and outlet of the saw cut of the Brown abrasive wheel saw to realize clamping and sawing of bars. The current hydraulic vertical clamping device is as Figure 1 shown, mainly composed of: a clamping arm 3', a linear guide rail, a slider and a hydraulic cylinder 8'. The piston rod of the hydraulic cylinder 8' faces downward, the top of the cylinder body of the hydraulic cylinder 8' is fixed on the sawing machine frame 1', the piston rod of the hydraulic cylinder 8' is connected to the inner side of the clamping arm 3' through a trunnion seat, and the whole hydraulic cylinder 8' is located inside the clamping arm 3'. When the piston rod of the hydraulic cylinder 8' extends, it pushes the whole clamping arm 3' to descend, and the cross beam 4' of the clamping arm 3' clamps the sawed steel downwards. When the piston rod retracts, the clamping arm 3' releases the steel and rises to the highest position, and the steel is conveyed by the front and rear roller tables through the saw cut. The linear guide rail is fixed on the sawing machine body 1', the slider is fixed on the clamping arm 3', and the linear guide rail and the slider slide relative to each other, so that the clamping arm 3' can be accurately lifted and lowered in the vertical direction. The current clamping arm 3' includes a clamping arm body, a cross beam connecting plate in a "√" shape and a cross beam 4'. The cross beam connecting plates are respectively welded on both sides of the clamping arm body, and the cross beam 4' is fixed between the tops of the two cross beam connecting plates 304'.

[0003] Currently, as Figure 1 shown, the hydraulic cylinder 8' is located between the clamping arm 3' and the sawing machine frame 1'. The top end of the cylinder barrel of the hydraulic cylinder 8' is fixed to the sawing machine frame 1', and the rod end of the piston rod at the bottom thereof is fixed to the clamping arm body. Since the hydraulic cylinder 8' is blocked by the clamping arm 3', without removing the clamping arm 3', it is impossible to see the hydraulic cylinder 8' located inside the clamping arm 3', and thus it is impossible to observe the oil leakage and seepage of the hydraulic cylinder 8'. Moreover, once the hydraulic cylinder 8' is damaged or needs maintenance, only by removing the whole clamping arm 3' can the repair or maintenance work be carried out, which is rather troublesome. Summary of the Invention

[0004] (1) The problem to be solved by the present invention is that in the traditional Brown abrasive wheel saw, since the hydraulic cylinder is blocked by the clamping arm, without removing the clamping arm, it is impossible to see the hydraulic cylinder located inside the clamping arm, and thus it is impossible to observe the oil leakage and seepage of the hydraulic cylinder. Moreover, once the hydraulic cylinder is damaged or needs maintenance, only by removing the whole clamping arm can the repair or maintenance work be carried out, which is rather troublesome.

[0032] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 2 - 9As shown in the figure, an embodiment of the present invention provides a Brown grinding wheel saw, which includes a saw machine frame 1, a hydraulic vertical clamping device, and a cover plate mechanism. There is a sawing station on the saw machine frame 1, and a sawing mechanism for sawing steel is installed above the sawing station;

[0034] There are two sets of hydraulic vertical clamping devices, which are arranged in sequence along the first direction on both sides of the sawing station. The first direction is the conveying direction of the steel. A cover plate mechanism is installed on the side of each set of hydraulic vertical clamping devices away from the sawing station. A sealed space is formed between the cover plate mechanism and the saw machine frame 1;

[0035] The hydraulic vertical clamping device includes a hydraulic cylinder 8, a clamping arm 3, and a guide rail mechanism. The guide rail mechanism is vertically installed on the saw machine frame 1, and the clamping arm 3 is slidably installed on the guide rail mechanism;

[0036] The bottom end of the hydraulic cylinder 8 is hinged to the saw machine frame 1, and the other end is hinged to the side of the clamping arm 3 facing the cover plate mechanism. The hydraulic cylinder 8 is located between the clamping arm 3 and the cover plate mechanism, and the projection of the hydraulic cylinder 8 in the second direction does not completely fall on the clamping arm 3; The first direction and the second direction are perpendicular to each other.

[0037] The above-mentioned first direction is the moving direction of the bar, or the length direction of the saw machine frame 1, and the second direction is the width direction of the saw machine frame 1.

[0038] In this embodiment, as Figure 2 shown, compared with the original hydraulic vertical clamping device, in this embodiment, the installation position of the hydraulic cylinder 8 is adjusted to the outside of the clamping arm 3 close to it, or the installation position of the hydraulic cylinder 8 is adjusted to the space between the clamping arm 3 and the cover plate mechanism, so that all or part of the hydraulic cylinder 8 is exposed outside the clamping arm 3. In this way, after removing the outer cover plate mechanism, the hydraulic cylinder 8 can be directly observed to facilitate checking for equipment hidden dangers such as oil leakage and seepage of the hydraulic cylinder 8, loosening of the pin shaft, and whether the articulated earring on the piston rod of the hydraulic cylinder 8 falls off. And when performing maintenance or repair on the hydraulic cylinder 8, since the clamping arm 3 no longer completely blocks the hydraulic cylinder 8, it is not necessary to remove the entire clamping arm 3, which greatly improves the maintenance or repair efficiency.

[0039] It should be noted that in the past, a cover plate mechanism was installed on the outside of the clamping arm 3'. The cover plate mechanism includes a vertical baffle 7' and an inclined cover plate 6'. Among them, the top end of the inclined cover plate 6' is connected to the saw machine frame 1', the vertical baffle 7' is located outside the clamping arm body, and the top end of the vertical baffle 7' is connected to the inclined cover plate 6'. Since the past vertical baffle 7' was composed of a whole piece of steel plate, only by removing the vertical baffle 7' could the internal clamping arm body be seen, and then by removing the clamping arm 3' could the hydraulic cylinder 8' inside the clamping arm 3' be seen.

[0040] In this embodiment, as Figure 2 , Figure 8 and Figure 9 shown, the cover plate mechanism in this embodiment includes an inclined cover plate 6 and a vertical baffle 7. The inclined cover plate 6 is inclined, the top end of the inclined cover plate 6 is fixedly connected to the sawing machine frame 1, the top end of the vertical baffle 7 is connected to the lower end of the inclined cover plate 6, and the inclined cover plate 6 is used to provide support for the vertical baffle 7. Further, a window is provided on the vertical baffle 7, and a transparent window plate 701 is detachably installed in the window. It should be noted that the hydraulic cylinder 8 and the transparent window plate 701 are opposite, that is, the projection of the hydraulic cylinder 8 along the width direction of the sawing machine frame 1 completely or partially falls into the transparent window plate 701. Since at least part of the hydraulic cylinder 8 is exposed outside the clamping arm body, the hydraulic cylinder 8 can be directly observed through the transparent window plate 701.

[0041] In this way, workers can directly observe the hydraulic cylinder 8 between the vertical baffle 7 and the clamping arm body through the transparent window plate 701 without removing the inclined cover plate 6 and the vertical baffle 7, which facilitates the observation of the hydraulic cylinder 8 at any time and is convenient for timely discovery of problems.

[0042] In this embodiment, the clamping arm 3 includes a clamping arm body, two cross beam connecting rods 304 and a cross beam 4. The clamping arm body includes a first side plate 301, a main plate 303 and a second side plate 302 connected in sequence. One cross beam connecting rod 304 is vertically installed on the side of the first side plate 301 away from the second side plate 302, and the other cross beam connecting rod 304 is vertically installed on the side of the second side plate 302 away from the first side plate 301. The cross beam connecting rod 304 is similar to a V-shaped rod, which includes a connected first rod body and a second rod body. The length of the first rod body is greater than that of the second rod body, the included angle between the first rod body and the second rod body is an obtuse angle, and the connection between the first rod body and the second rod body is in arc transition. The first rod body is vertically arranged, and the second rod body bends towards the middle of the sawing machine frame 1. The cross beam 4 is installed between the top ends of the second rod bodies of the two cross beam connecting rods 304.

[0043] It should be noted that the surface of the first side plate 301 away from the vertical baffle 7, the surface of the second side plate 302 away from the vertical baffle 7, and the surface of the main plate 303 away from the vertical baffle 7 are located in the same vertical plane. The surface of the first side plate 301 facing the vertical baffle 7 and the surface of the second side plate 302 facing the vertical baffle 7 are located in the same vertical plane. The thicknesses of the first side plate 301 and the second side plate 302 are the same, and the thickness of the main plate 303 is slightly smaller than that of the first side plate 301. That is, an installation station for installing the hydraulic cylinder 8 is reserved between the first side plate 301, the main plate 303 and the second side plate 302, and the depth of this installation station is smaller than the diameter of the hydraulic cylinder 8. As Figure 2As shown, when installing the hydraulic cylinder 8, only the left part of the hydraulic cylinder 8 is located within the installation station between the first side plate 301 and the second side plate 302, while the other part of the hydraulic cylinder 8 is exposed to the outside, that is, exposed to the space between the clamping arm body and the vertical baffle 7.

[0044] Furthermore, as Figure 5 shown, two shaft seats 305 are installed on the side of the main board 303 facing the vertical baffle 7, and the rod end of the piston rod of the hydraulic cylinder 8 is hinged to these two shaft seats 305 through a pin shaft.

[0045] In this embodiment, as Figure 2 shown, a hydraulic cylinder base 2 is installed at the bottom of the side of the sawing machine frame 1. The hydraulic cylinder base 2 extends along the width direction of the sawing machine frame 1. The hydraulic cylinder base 2 is as Figure 3 and Figure 4 shown, and it includes a connecting base 201 and two fixing plates 202. The connecting base 201 is fixedly installed on the sawing machine frame 1 through bolts. A first pin shaft 203 is installed between the two fixing plates 202, and the bottom of the cylinder barrel of the hydraulic cylinder 8 is rotatably connected to the two fixing plates 202.

[0046] It should be noted that the two shaft seats 305 on the main board 303 are located directly above the two fixing plates 202 on the hydraulic cylinder base 2. The bottom of the cylinder barrel of the hydraulic cylinder 8 is hinged to the two fixing plates 202 on the hydraulic cylinder base 2 through a pin shaft, and the rod end of the piston rod at the top of the hydraulic cylinder 8 is hinged to the two shaft seats 305 on the main board 303 through a pin shaft, so that the hydraulic cylinder 8 is in a vertical state.

[0047] As another alternative embodiment, the surface of the main board 303 facing the vertical baffle 7, the surface of the first side plate 301 facing the vertical baffle 7, and the surface of the second side plate 302 facing the vertical baffle 7 are located in the same vertical plane. Two shaft seats 305 are installed on the surface of the main board 303 facing the vertical baffle 7, and these two shaft seats 305 are located within the space between the clamping arm body and the vertical baffle 7. Furthermore, a hydraulic cylinder base 2 is installed at the bottom of the side of the sawing machine frame 1. The fixing plates 202 on the hydraulic cylinder base 2 are located directly below the shaft seats 305 on the main board 303. The piston rod of the hydraulic cylinder 8 is hinged to the two shaft seats 305 on the main board 303 through a pin shaft, and the bottom of the cylinder barrel of the hydraulic cylinder 8 is rotatably connected to the two fixing plates 202 on the hydraulic cylinder base 2 through the first pin shaft 203. In this way, the entire hydraulic cylinder 8 is located within the space between the clamping arm 3 and the vertical baffle 7, that is, the entire hydraulic cylinder 8 is located on the side of the clamping arm 3 facing the vertical baffle 7. Thus, since the clamping arm body does not block the hydraulic cylinder 8 at all, the worker can directly observe the hydraulic cylinder 8 through the transparent window plate 701, which is convenient for observing the specific situation of the hydraulic cylinder 8 at any time. During subsequent maintenance and repair, it is not necessary to disassemble the clamping arm 3.

[0048] It should be understood that as Figure 1 shown, in the past, the top of the cylinder block of the hydraulic cylinder 8' was fixedly installed on the saw machine frame 1', and the rod end of the piston rod of the hydraulic cylinder 8' was connected to the clamping arm body through a trunnion seat. When the piston rod of the hydraulic cylinder 8 extends, it pushes the entire clamping arm 3' downward, so that the crossbeam 4' moves downward to clamp the steel on the roller table. When the piston rod of the hydraulic cylinder 8' shortens, it pulls the entire clamping arm 3' upward, thus driving the crossbeam 4' to rise to release the steel on the roller table.

[0049] However, a problem will occur in the actual production process: in the original design, since the piston rod faces downward, the force-bearing area of the hydraulic oil in the piston rod cavity is the area of the piston minus the cross-sectional area of the piston rod, that is, the area of the ring. When the hydraulic cylinder 8' is self-locked, it is also necessary to offset the self-weight of the hydraulic cylinder 8'. In this embodiment, the piston rod of the hydraulic cylinder 8 faces upward, and the bottom end of the hydraulic cylinder 8 acts on the hydraulic cylinder base 2. Therefore, when the clamping arm 3 is self-locked at a high position, the force-bearing area of the hydraulic oil in the rodless cavity of the hydraulic cylinder is the area of the piston, which is larger than the area of the ring. The pressure required for self-locking with the piston rod facing downward in the original design is greater than the pressure required for self-locking of the hydraulic cylinder 8 in this embodiment. The greater the pressure, the higher the requirement for sealing, and the easier it is to cause leakage. Once leakage occurs during self-locking, the crossbeam 4' will slide down and collide with the steel, which will cause the crossbeam 4' of the clamping arm 3' to be deformed. After the transformation, the required hydraulic oil pressure is smaller, so the probability of the clamping arm 3 sliding down automatically and being damaged is greatly reduced. Thus, it effectively avoids the deformation of the crossbeam 4 caused by the collision between the crossbeam 4 and the steel.

[0050] Specifically, the hydraulic cylinder 8 in this embodiment includes a cylinder barrel 801, a front end cover, a rear end cover, a piston rod 803, a first pin mounting seat 802, and a second pin mounting seat 804. As Figure 7 shown, the front end cover is installed on the left side of the cylinder barrel 801, the rear end cover is installed on the right side of the cylinder barrel 801, the piston slides inside the cylinder barrel 801, the piston rod 803 is connected to the piston, the rod end of the piston rod 803 is installed with a second pin mounting seat 804, and the first pin mounting seat 802 is installed on the rear end cover.

[0051] In this embodiment, the first pin mounting seat 802 on the rear end cover of the hydraulic cylinder 8 is hinged to two fixing plates 202 on the hydraulic cylinder base 2 through a first pin 203, and the second pin mounting seat 804 at the end of the piston rod 803 of the hydraulic cylinder 8 is hinged to two shaft seats on the main board 303 through a second pin.

[0052] As a specific embodiment, as Figure 8 and Figure 9As shown, a rectangular groove is provided on the vertical baffle 7, a rectangular mounting hole is provided in the rectangular groove, and a plurality of threaded holes are provided in the area between the inner wall of the rectangular mounting hole and the rectangular groove. The transparent window plate 701 is adapted to the rectangular groove, and the transparent window plate 701 is fixedly installed in the rectangular groove by a locking screw 702 and completely covers the rectangular mounting hole.

[0053] In this way, when installing the transparent window plate 701, only need to cover the transparent window plate 701 into the rectangular groove of the vertical baffle 7, and then screw on the screw or bolt.

[0054] It should be noted that in the past, two supporting plates 5' were usually installed at the sawing station of the Brown grinding wheel saw, namely the inlet supporting plate and the outlet supporting plate, and the function of these two supporting plates 5' was to support the steel. In the past, the distance between the inlet supporting plate and the outlet supporting plate was relatively small, usually 28 mm, and the distance between the supporting plate 5' and the grinding wheel saw blade 9' was only 10 mm. A large amount of sawdust is generated during the sawing of steel, and these sawdusts are easy to block the gap between the supporting plate 5' and the grinding wheel saw blade 9', thus easily causing damage to the saw blade.

[0055] In this embodiment, the distance between the two supporting plates 5 is adjusted to 71 mm to ensure that there is enough space for the sawdust to pass through between the supporting plate 5 and the grinding wheel saw blade 9, thereby reducing the accident of saw blade explosion, ensuring the normal operation of the saw blade, not easily blocking the saw seam, greatly saving the time for manual slag cleaning during production stoppage, and improving the sawing efficiency.

[0056] In addition, at present, the total thickness of the two saw blade chucks 9 and the grinding wheel saw blade 10 is 98 mm, where the thickness of a single saw blade chuck 9 is 40 mm and the thickness of the grinding wheel saw blade 10 is 18 mm.

[0057] In the past, the distance between the cross beams 4' of the two clamping arms 3' was usually 48 mm. Therefore, when the saw blade is worn to a certain extent, due to the gap between the two cross beams 4' blocking the further downward movement of the saw blade chuck 9, the saw blade at this time can no longer cut the steel on the supporting plate 5'.

[0058] To solve this technical problem, in this embodiment, the distance between the cross beams 4 of the clamping arms 3 at the inlet and outlet is increased from 48 mm to 128 mm. In this way, when the saw blade is worn to a certain extent, since the saw blade chuck 9 and the saw blade can continue to descend and enter between the two cross beams 4, the saw blade at this time can still saw the steel, so the utilization rate of the saw blade is increased by 11%, reducing the saw blade consumption and the frequency of saw blade replacement.

[0059] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0060] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.
