Description

Technical Field

[0001] This invention relates to the field of abrasive wheel saw technology, and specifically to a Brown abrasive wheel saw. Background Technology

[0002] Brown's wheel saw is a device used for segmenting and cutting continuously rolled steel into sections and lengths, widely used in the special steel industry. The inlet and outlet of the Brown's wheel saw kerf are each equipped with a hydraulically driven vertical clamping device to clamp and saw the bars. Current hydraulic vertical clamping devices include... Figure 1 As shown, it mainly consists 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 downwards, and the top of the cylinder body of the hydraulic cylinder 8' is fixed to the saw 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 entire hydraulic cylinder 8' is located inside the clamping arm 3'. When the piston rod of the hydraulic cylinder 8' extends, it pushes the clamping arm 3' to descend as a whole, and the crossbeam 4' of the clamping arm 3' clamps the sawn steel downwards. When the piston rod retracts, the clamping arm 3' releases the steel and rises to its highest position. The steel is then conveyed through the saw cut by the front and rear roller conveyors. The linear guide rail is fixed to the saw body 1', and the slider is fixed to the clamping arm 3'. The linear guide rail and the slider slide relative to each other, allowing the clamping arm 3' to move precisely up and down in the vertical direction. The current clamping arm 3' includes a clamping arm body, a "√"-shaped crossbeam connecting plate, and a crossbeam 4'. The crossbeam connecting plates are welded to both sides of the clamping arm body, and the crossbeam 4' is fixed between the tops of the two crossbeam connecting plates 304'.

[0003] Currently, such as Figure 1 As shown, the hydraulic cylinder 8' is located between the clamping arm 3' and the saw frame 1'. The top of the cylinder barrel of the hydraulic cylinder 8' is fixed to the saw frame 1', and the end of the piston rod at its bottom is fixed to the clamping arm body. Because the hydraulic cylinder 8' is obscured by the clamping arm 3', it is impossible to see the hydraulic cylinder 8' located inside the clamping arm 3' without removing the clamping arm 3', and therefore it is impossible to observe the oil leakage of the hydraulic cylinder 8'. Furthermore, if the hydraulic cylinder 8' is damaged or requires maintenance, the entire clamping arm 3' must be disassembled for repair or maintenance, which is quite troublesome. Summary of the Invention

[0004] (I) The problem to be solved by the present invention is that in the traditional Brown abrasive wheel saw, the hydraulic cylinder is blocked by the clamping arm. Without removing the clamping arm, the hydraulic cylinder located inside the clamping arm cannot be seen, and the oil leakage of the hydraulic cylinder cannot be observed. Moreover, once the hydraulic cylinder is damaged or needs maintenance, the entire clamping arm can be removed to carry out the repair or maintenance work, which is quite troublesome.

A sealed space is formed between the cover plate mechanism and the saw frame.

[0008] The hydraulic vertical clamping device includes a hydraulic cylinder, a clamping arm, and a guide rail mechanism. The guide rail mechanism is vertically mounted on the saw frame, and the clamping arm is slidably mounted on the guide rail mechanism.

[0010] According to one embodiment of the present invention, the cover plate mechanism includes a vertical baffle, a viewing window is provided on the vertical baffle, and a transparent window plate is detachably installed in the viewing window, and the projection of the hydraulic cylinder along the first direction falls completely or partially into the transparent window plate.

[0011] According to one embodiment of the present invention, the cover plate mechanism further includes an inclined cover plate, the first end of which is fixedly connected to the saw frame, the second end of which is lower than the first end, and the top end of the vertical baffle is connected to the second end of the inclined cover plate. The inclined cover plate is used to provide support for the vertical baffle.

[0012] According to one embodiment of the present invention, the clamping arm includes a clamping arm body, two crossbeam connecting rods, and a crossbeam. The clamping arm body is parallel to the vertical baffle. The two crossbeam connecting rods are arranged and installed on the clamping arm body along a second direction.

[0014] According to one embodiment of the present invention, a hydraulic cylinder base is fixed to the bottom of the saw frame. The hydraulic cylinder base includes a connecting base and two fixing plates. The connecting base is detachably installed on the saw frame. The two fixing plates are arranged along a second direction and installed on the side of the connecting base facing the vertical baffle. A first pin is installed between the two fixing plates.

[0015] According to one embodiment of the present invention, the bottom of the hydraulic cylinder is hinged between the two fixed plates by a first pin, and the piston rod of the hydraulic cylinder is hinged between the two bearings by a second pin.

[0016] According to one embodiment of the present invention, the viewing window includes a rectangular groove formed on the side of the vertical baffle away from the clamping arm, a rectangular mounting hole is formed in the rectangular groove, the transparent window plate is adapted to the rectangular groove, and the transparent window plate is detachably installed in the rectangular groove to close the rectangular mounting hole.

[0019] The beneficial effects of this invention are:

In this way, after removing the outer cover plate mechanism, the hydraulic cylinder can be directly observed, making it convenient to check whether there is any oil leakage. Furthermore, when repairing or maintaining the hydraulic cylinder, since the clamping arm no longer completely covers the hydraulic cylinder, it is not necessary to disassemble the entire clamping arm, which greatly improves the efficiency of repair or maintenance.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 2-9As shown, one embodiment of the present invention provides a Brown abrasive wheel saw, including a saw frame 1, a hydraulic vertical clamping device and a cover plate mechanism. The saw frame 1 has a sawing station, and a sawing mechanism for sawing steel is installed above the sawing station.

[0034] Two sets of hydraulic vertical clamping devices are provided. The two sets of hydraulic vertical clamping devices are arranged in sequence on both sides of the sawing station along the first direction, which is the direction of steel conveying. Each set of hydraulic vertical clamping devices is equipped with a cover plate mechanism on the side away from the sawing station. A sealed space is formed between the cover plate mechanism and the saw 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 mounted on the saw frame 1, and the clamping arm 3 is slidably mounted on the guide rail mechanism.

[0036] The bottom end of the hydraulic cylinder 8 is hinged to the saw 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 along the second direction does not fall completely on the clamping arm 3; the first direction and the second direction are perpendicular to each other.

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

[0038] In this embodiment, as Figure 2 As shown, compared to the original hydraulic vertical clamping device, in this embodiment, the installation position of the hydraulic cylinder 8 is adjusted to be closer to the outside of the clamping arm 3, or the installation position of the hydraulic cylinder 8 is adjusted to be in the space between the clamping arm 3 and the cover plate mechanism, so that all or part of the hydraulic cylinder 8 is exposed to the outside of the clamping arm 3. In this way, after removing the outer cover plate mechanism, the hydraulic cylinder 8 can be directly observed, so as to facilitate checking whether there are potential equipment hazards such as oil leakage, loose pins, or whether the hinge lugs on the piston rod of the hydraulic cylinder 8 have fallen off. Moreover, when repairing or maintaining the hydraulic cylinder 8, since the clamping arm 3 no longer completely covers the hydraulic cylinder 8, it is not necessary to disassemble the entire clamping arm 3, which greatly improves the efficiency of repair or maintenance.

[0039] It should be noted that the conventional clamping arm 3' had a cover plate mechanism installed on its outer side. The cover plate mechanism included a vertical baffle 7' and an inclined cover plate 6'. The top of the inclined cover plate 6' was connected to the saw frame 1', and the vertical baffle 7' was located on the outer side of the clamping arm body, with its top connected to the inclined cover plate 6'. Because the conventional vertical baffle 7' was made of a single piece of steel plate, the clamping arm body inside could only be seen after the vertical baffle 7' was removed, and then the hydraulic cylinder 8' located inside the clamping arm 3' could only be seen after the clamping arm 3' was removed.

[0040] In this embodiment, such as Figure 2 , Figure 8 and Figure 9 As 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, and its top end is fixedly connected to the saw frame 1. The top end of the vertical baffle 7 is connected to the bottom end of the inclined cover plate 6, and the inclined cover plate 6 provides support for the vertical baffle 7. Furthermore, a viewing window is provided on the vertical baffle 7, and a transparent window plate 701 is detachably installed inside the viewing window. It should be noted that the hydraulic cylinder 8 and the transparent window plate 701 are opposite each other, that is, the projection of the hydraulic cylinder 8 along the width direction of the saw frame 1 falls completely or partially into the transparent window plate 701. Since the hydraulic cylinder 8 is at least partially 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 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 makes it easier to detect problems in a timely manner.

[0042] In this embodiment, the clamping arm 3 includes a clamping arm body, two crossbeam connecting rods 304, and a crossbeam 4. The clamping arm body includes a first side plate 301, a main plate 303, and a second side plate 302 connected thereto. One crossbeam 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 crossbeam connecting rod 304 is vertically installed on the side of the second side plate 302 away from the first side plate 301. The crossbeam connecting rod 304 is similar to a V-shaped rod, comprising a first rod body and a second rod body connected together. The length of the first rod body is greater than the length 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 a rounded transition. The first rod body is vertically arranged, and the second rod body is bent towards the center of the saw frame 1. The crossbeam 4 is installed between the top ends of the second rod bodies of the two crossbeam connecting rods 304.

[0043] It should be noted that the side of the first side plate 301 away from the vertical baffle 7, the side of the second side plate 302 away from the vertical baffle 7, and the side of the main plate 303 away from the vertical baffle 7 are located on the same vertical plane. The side of the first side plate 301 facing the vertical baffle 7 and the side of the second side plate 302 facing the vertical baffle 7 are also located on the same vertical plane. The first side plate 301 and the second side plate 302 have the same thickness, and the thickness of the main plate 303 is slightly less than the thickness of the first side plate 301. That is, an installation position for installing the hydraulic cylinder 8 is reserved between the first side plate 301, the main plate 303, and the second side plate 302. The depth of this installation position is less than the diameter of the hydraulic cylinder 8. Figure 2As shown, when installing the hydraulic cylinder 8, only the left side of the hydraulic cylinder 8 is located in the installation position 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 in the space between the clamping arm body and the vertical baffle 7.

[0044] Furthermore, such as Figure 5 As shown, two bearing 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 the two bearing seats 305 by a pin.

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

[0046] It should be noted that the two bearing 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 by a pin. The rod end of the piston rod at the top of the hydraulic cylinder 8 is hinged to the two bearing seats 305 on the main board 303 by a pin, so that the hydraulic cylinder 8 is in a vertical state.

[0047] As another optional embodiment, the side of the main board 303 facing the vertical baffle 7, the side of the first side plate 301 facing the vertical baffle 7, and the side of the second side plate 302 facing the vertical baffle 7 are located on the same vertical plane. Two bearing seats 305 are installed on the side of the main board 303 facing the vertical baffle 7, and these two bearing seats 305 are located in the space between the clamping arm body and the vertical baffle 7. Further, a hydraulic cylinder base 2 is installed at the bottom of the side of the saw frame 1. The fixing plate 202 on the hydraulic cylinder base 2 is located directly below the bearing seats 305 on the main board 303. The piston rod of the hydraulic cylinder 8 is hinged to the two bearing seats 305 on the main board 303 by a pin. 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 by a first pin 203. In this way, the hydraulic cylinder 8 is located entirely in the space between the clamping arm 3 and the vertical baffle 7, that is, the hydraulic cylinder 8 is located entirely on the side of the clamping arm 3 facing the vertical baffle 7. Thus, since the clamping arm body does not obstruct the hydraulic cylinder 8 at all, the worker can directly observe the hydraulic cylinder 8 through the transparent window 701, which makes it convenient to observe the specific condition of the hydraulic cylinder 8, and the clamping arm 3 does not need to be disassembled during subsequent maintenance and repair.

[0048] It is necessary to understand that, such as Figure 1 As shown, in the conventional hydraulic cylinder 8', the top of the cylinder body is fixedly mounted on the saw frame 1', and the piston rod of the hydraulic cylinder 8' is connected to the clamping arm body via a trunnion seat. When the piston rod of the hydraulic cylinder 8' extends, it pushes the clamping arm 3' to move downwards as a whole, thereby causing the crossbeam 4' to move downwards to clamp the steel on the roller conveyor. When the piston rod of the hydraulic cylinder 8' shortens, it pulls the clamping arm 3' to rise as a whole, thereby causing the crossbeam 4' to rise and release the steel on the roller conveyor.

[0049] However, a problem arises in actual production: In the original design, with the piston rod pointing downwards, the hydraulic oil pressure area in the piston rod chamber was the piston area minus the piston rod cross-sectional area, i.e., the annular area. When the hydraulic cylinder 8' self-locks, it also needs to offset the weight of the hydraulic cylinder 8'. In this embodiment, the piston rod of the hydraulic cylinder 8 points upwards, and the bottom of the hydraulic cylinder 8 acts on the hydraulic cylinder base 2. Therefore, when the clamping arm 3 self-locks at a high position, the hydraulic oil pressure area in the rodless chamber of the hydraulic cylinder is equal to the piston area, which is greater than the annular area. The pressure required for self-locking when the piston rod points downwards in the original design is greater than the pressure required for self-locking of the hydraulic cylinder 8 in this embodiment. Higher pressure places higher sealing requirements and increases the likelihood of leakage. If leakage occurs during self-locking, the crossbeam 4' will slide down and collide with the steel, causing deformation of the clamping arm 3'. With the modification, the required hydraulic oil pressure is lower, greatly reducing the probability of the clamping arm 3 automatically sliding down and being damaged. This effectively avoids deformation of the crossbeam 4 due to collision with the steel.

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

[0051] In this embodiment, the first pin mounting seat 802 of the rear end cover of the hydraulic cylinder 8 is hinged to the two fixing plates 202 on the hydraulic cylinder base 2 via the 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 the two bearing seats on the main board 303 via the second pin.

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

[0053] Thus, when installing the transparent window panel 701, simply place the transparent window panel 701 into the rectangular groove of the vertical baffle 7, and then tighten the screws or bolts.

[0054] It should be noted that traditionally, Brown abrasive wheel saws typically have two support plates 5' installed at the sawing station: an inlet support plate and an outlet support plate. These two support plates 5' are used to support the steel. Previously, the distance between the inlet and outlet support plates was relatively small, usually 28mm, and the distance between the support plate 5' and the abrasive wheel saw blade 9' was only 10mm. When sawing steel, a large amount of sawdust is generated, which can easily clog the gap between the support plate 5' and the abrasive wheel saw blade 9', thus easily damaging the saw blade.

[0055] In this embodiment, the distance between the two support plates 5 is adjusted to 71mm to ensure that the gap between the support plate 5 and the saw blade 9 is large enough for saw chips to pass through, thereby reducing the risk of saw blade breakage, ensuring normal operation of the saw blade, preventing clogging of the saw kerf, greatly saving downtime for manual cleaning of slag, and improving sawing efficiency.

[0056] In addition, the total thickness of the two saw blade chucks 9 and the abrasive saw blade 10 is currently 98mm, of which the thickness of a single saw blade chuck 9 is 40mm and the thickness of the abrasive saw blade 10 is 18mm.

[0057] Previously, the gap between the crossbeams 4' of the two clamping arms 3' was usually 48mm. Therefore, when the saw blade was worn to a certain extent, the gap between the two crossbeams 4' prevented the saw blade chuck 9 from moving further down, and the saw blade could no longer cut the steel located on the support plate 5'.

[0058] To address this technical problem, in this embodiment, the distance between the crossbeams 4 of the clamping arms 3 at the inlet and outlet is increased from 48mm to 128mm. Thus, when the saw blade wears to a certain extent, the saw blade chuck 9 and the saw blade can continue to descend and enter between the two crossbeams 4, allowing the saw blade to still cut steel. This increases the saw blade utilization rate by 11%, reducing saw blade consumption and the frequency of saw blade replacement.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components.
