Description

Technical Field

[0001] This utility model relates to the field of bar processing technology, and in particular to a fixture and sawing equipment for sawing. Background Technology

[0002] Abrasive wheel saws are commonly used equipment in metallurgical bar rolling processing units. They are used to cut produced bars into segments of the required length using a sizing machine. At the sawing station of the abrasive wheel saw, the bars need to be fixed in place before cutting. Specifically, support plates are installed on both sides of the saw kerf, arranged horizontally at the top of the equipment. The bars are supported on these support plates, with the bar's axis perpendicular to the saw blade. During operation, the support plates on both sides of the saw kerf support the steel to prevent it from sinking during sawing, ensuring a smooth cut. Because the support plates are in constant contact with the steel, wear will occur on their surfaces. When the wear reaches a certain level, a gap may appear between the support plate and the bottom of the steel. During sawing, the steel may sink, becoming unstable at the sawing station, easily causing uneven cuts and affecting the quality of the steel cut. Alternatively, if the steel is not properly clamped during sawing, displacement may occur, causing the saw blade to break and damage. Therefore, it is necessary to replace the support plates. Currently, at the sawing station, the existing support plates at the bottom are fixed to the support plate base with bolts or pins. Due to the high temperature deformation and sawdust accumulation caused by sawing, it is difficult to disassemble the bolts or pins. In addition, there are positioning components at the sawing station, and the operating space is also limited. Therefore, it is even more difficult to disassemble the bolts or pins, resulting in difficulty in replacing the support plate, a long replacement time, and high labor intensity for workers.

[0003] Therefore, solving the problem of difficulty in replacing pallets is an urgent issue that needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for sawing equipment and sawing equipment in which the connection between the pallet and the pallet seat is stable, disassembly and installation are convenient, the labor intensity of workers is reduced, and the pallet replacement time is reduced, thereby improving work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixture for a sawing machine, comprising:

[0007] A support assembly includes two support portions respectively disposed on both sides of the cutting path and extending along a first direction, the two support portions being spaced apart along a second direction, the first direction being perpendicular to the second direction and parallel to the cutting direction, and the second direction being parallel to the transport direction of the bar; wherein each support portion includes a tray seat and a tray plate, the tray seat extending along the first direction, the tray plate being disposed on the top side of the tray seat, and the surface of the tray plate facing away from the tray seat forming a support surface for supporting the bar; the top of the tray seat is provided with a protruding snap-fit ​​portion, and the side of the tray plate facing the tray seat is provided with a snap-fit ​​groove that engages with the protruding snap-fit ​​portion, the snap-fit ​​groove penetrating the tray plate along the first direction; or, the top of the tray seat is provided with a snap-fit ​​groove extending through along the first direction, and the side of the tray plate facing the tray seat is provided with a protruding snap-fit ​​portion that engages with the snap-fit ​​groove.

[0008] A first positioning component, comprising a horizontal positioning part, wherein the horizontal positioning part is position-adjustable along the first direction and is used to position the bar along the first direction;

[0009] The second positioning component includes a vertical positioning part located on the side of the pallet away from the pallet seat. The vertical positioning part is adjustable along a third direction and is used to position the bar along the third direction, which is perpendicular to the first direction and also perpendicular to the second direction.

[0010] The aforementioned sawing equipment uses a clamping fixture to fix the bars. The clamping fixture is located at the cutting station, and both sides of the cutting station are equipped with conveying components for transporting the bars. Multiple bars extend along a second direction and are arranged in a first direction. The transport direction of the bars is parallel to the second direction. During transport, multiple bars are transported simultaneously, and multiple bars are cut in a single cutting process at the cutting station. In the transport direction, ahead of the transport front end of the bars, a length-fixing machine is provided to restrict the forward transport of the bars. The length-fixing machine includes a fixed beam and a movable beam. The movable beam is movably mounted on the fixed beam along the second direction and can move back and forth in the second direction. A lifting baffle is provided on the movable beam, and the length-fixing baffle is movably mounted on the movable beam along a third direction. The ruler baffle can move up and down. The fixed-length baffle can stop the bar when it descends. The distance between the fixed-length baffle and the cutting path is the size of the bar being cut, which is the size of the bar after cutting. Specifically, when multiple bars are conveyed in the conveying direction and pass through the cutting station, when the front end of the bar contacts and abuts the fixed-length baffle, the forward conveying stops and the multiple bars are fixed in the conveying direction. At this time, at the cutting station, two support parts support the bar. The first positioning component fixes the bar in the first direction, and the second positioning component fixes the bar in the vertical direction. The cutting saw can cut multiple bars along the cutting path. During the cutting process, the two support parts support the bar stably. The first positioning component and the second positioning component work together with the support parts to fix the bar, ensuring the cutting quality and making the bar cross-section flat.

[0011] In particular, the support surface of the pallet plays an important role in supporting the bar stock. As the bar stock rubs against the support surface of the pallet during transportation, and the long-term contact and friction between the bar stock and the support surface of the pallet causes wear. When the wear reaches a certain level, a gap will appear between the bottom of the pallet and the bar stock. If the gap is too large, the bar stock will sink during cutting, resulting in an uneven cut surface and seriously affecting the cutting quality of the bar stock. Therefore, the pallet needs to be replaced regularly.

[0012] Compared to existing technologies that use bolts or pins for fixing, where high-temperature deformation from cutting and sawdust buildup can clog the connection holes, making bolt or pin removal difficult, this embodiment features a protruding locking part on the pallet seat and a locking groove on the pallet, or vice versa. The pallet seat and the pallet are connected by the protruding locking part and the locking groove, facilitating disassembly. The locking groove is a continuous groove in the first direction, and the mating surface between the locking groove and the protruding locking part is large, preventing severe jamming due to slight deformation. This facilitates disassembly, and the protruding locking part allows for easy removal during disassembly. The locking part and the slot are detached from each other, reducing the labor intensity of workers. During installation, the protruding locking part is simply aligned with the slot and pressed tightly, making installation very convenient, saving time and effort, and also saving some operating space. When installing or removing the tray, both the horizontal and vertical positioning parts are adjusted to positions away from the tray, leaving as much operating space as possible around the tray to facilitate installation or removal operations. Therefore, the connection between the tray and the tray base in this solution is stable, easy to disassemble and install, reduces the labor intensity of workers, and helps to reduce tray replacement time and improve work efficiency.

[0013] Optionally, the protruding engagement portion includes a strip-shaped protrusion extending along the first direction, and the strip-shaped protrusion has a rectangular cross-section perpendicular to the first direction; or,

[0014] The protruding engagement portion includes a plurality of protruding posts spaced apart along the first direction.

[0015] Optionally, in the second direction, the protruding snap-fit ​​portion engages with the slot with a clearance.

[0016] Optionally, the tray has a split structure, and the tray includes at least two sub-trays distributed along the first direction, with adjacent sub-trays in contact with each other.

[0017] Optionally, the tray has a groove on its end face along the first direction, and when the slot is provided on the tray, the groove avoids the opening of the slot on the end face.

[0018] Optionally, each of the tray seats is provided with a limiting boss at both ends in the first direction, and the limiting boss is used to limit the tray in the first direction.

[0019] Optionally, the limiting boss and the tray seat have an integral structure; or,

[0020] The limiting boss is welded to the support plate seat.

[0021] Optionally, the first positioning component includes:

[0022] Two guide rails are provided, which extend along the first direction and are respectively located on the two outer sides of the two support portions in the second direction.

[0023] Two push blocks are provided, each corresponding to one of the two guide rails. The push blocks and guide rails are slidably engaged, and the push blocks constitute the horizontal positioning part.

[0024] A first driving device that is connected to the push block and is used to drive the push block to move along the guide rail;

[0025] A limiting baffle is provided on the side of the pushing block facing the rod and is spaced apart from and opposite to the pushing block. The gap between the pushing block and the limiting baffle is used for the transmission of the rod.

[0026] Optionally, the second positioning component includes:

[0027] Two clamping blocks extend along the first direction and are respectively located on both sides of the cutting path, and the two clamping blocks are located on the side of the pallet away from the pallet seat;

[0028] A vertical track is provided corresponding to each of the two clamping blocks. The clamping blocks are movably mounted on the vertical track in a third direction via a connecting frame. The clamping blocks constitute the vertical positioning part.

[0029] A second drive device for driving the action of the clamping block.

For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0038] refer to Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a fixture for a sawing device. For ease of explanation, the direction parallel to the support surface of the pallet 12 is considered the horizontal direction, and the direction perpendicular to the support surface of the pallet 12 is considered the vertical direction. Specifically, the fixture for the sawing device in this embodiment includes: a support assembly, a first positioning assembly 2, and a second positioning assembly 3. The support assembly includes: two support parts 1, both of which extend along a first direction and are arranged in parallel. The two support parts 1 are arranged at intervals along a second direction, and the cutting path A of the saw of the sawing device is between the intervals of the two support parts 1, that is, the two support parts 1 are respectively arranged on both sides of the cutting path A. The first direction is parallel to the cutting direction, the second direction is parallel to the transmission direction of the bar 5, and the first direction is perpendicular to the second direction.

[0039] Specifically, each support 1 includes a tray seat 11 and a tray 12. The tray seat 11 extends along a first direction, and a side plate is provided below the tray seat 11. The tray seat 11 is mounted on the frame of the equipment via the side plate. The tray 12 is located above the tray seat 11 and mounted on the top side of the tray seat 11. The tray 12 also extends along the first direction. The length of the tray 12 is the same as that of the tray seat 11 in the first direction, or the length of the tray 12 is slightly shorter than that of the tray seat 11. The surface of the tray 12 facing away from the tray seat 11 forms a support surface for supporting the rod 5. The upper surface of the tray 12 forms a support surface for supporting the rod 5. The gap between the pallets is used for the cutting saw to pass through, which can be called the saw kerf; between the pallet seat 11 and the pallet 12, a protruding snap-fit ​​part is provided on the top of the pallet seat 11, and a slot is provided on the side of the pallet 12 facing the pallet seat 11 to engage with the protrusion. The slot extends through the pallet 12 along the first direction. The protruding snap-fit ​​part on the top side of the pallet seat 11 can be embedded in the slot on the bottom side of the pallet 12. The protruding snap-fit ​​part and the slot are perfectly engaged, so that the pallet 12 is connected to the pallet seat 11. Alternatively, a slot extending through the pallet seat 11 along the first direction is provided on the top of the pallet seat 11, and a protruding snap-fit ​​part that engages with the slot is provided on the side of the pallet 12 facing the pallet seat 11.

[0040] In addition, the first positioning component 2 includes a horizontal positioning part 21, which is adjustable along the first direction and can push the rod 5 to the limit baffle for clamping and positioning in the first direction. During cutting, the first positioning component 2 can fix the rod 5 in the first direction. The second positioning component 3 includes a vertical positioning part 31, which is located on the side of the support plate 12 away from the support plate seat 11. The vertical positioning part 31 is adjustable along the third direction and can position the rod in the third direction. The third direction is perpendicular to the first direction and perpendicular to the second direction. The vertical positioning part 31 is above the support plate 12. During cutting, the rod 5 is located between the vertical positioning part 31 and the support plate 12. The vertical positioning part 31 can press the rod 5 in the vertical direction, so that the rod 5 is fixed in the vertical direction, which is convenient for cutting.

[0041] The aforementioned sawing equipment uses a clamping fixture to fix the bar stock. The clamping fixture is positioned at the cutting station. In the bar stock transport direction, based on the cutting path, the position before the cutting path is called "before sawing," and the position after the cutting path is called "after sawing." Specifically, two transport components can be set within the transport channel, one on each side of the cutting path, i.e., one set of transport components before and one set after sawing. Each transport component includes a transport base, a transport frame, and four support rollers. The axis of each support roller extends parallel to a first direction, and the support rollers are arranged along a second direction. Each support roller is rotatably mounted on the transport frame around its own axis. The support rollers support and transport the bar stock. The transport frame is vertically adjustable and mounted on the transport base. The transport frame, carrying the support rollers, moves up and down. Each support roller can be equipped with a corresponding motor, which is fixed to the transport frame and drives the corresponding support roller to rotate. Preferably, each transport component is an independent component and can be controlled independently. Additionally, in the transmission direction, ahead of the transmission head, a length-fixing machine is provided to restrict the forward transport of the bar. The length-fixing machine includes a fixed beam and a movable beam. The movable beam is movably mounted on the fixed beam in a second direction and can move back and forth in the second direction. A length-fixing baffle is provided on the movable beam and is movably mounted on the movable beam in a third direction. The length-fixing baffle can move up and down. When the length-fixing baffle descends, it can block the bar. The distance between the length-fixing baffle and the cutting path A is the size of the bar cut, which is the size of the bar after cutting.

[0042] In one sawing cycle, multiple bars extend along the second direction and are arranged in the first direction. The transmission direction of the bars is parallel to the second direction. During the transmission of the bars, the support rollers are positioned at a high position, so that the top surface of the support rollers is higher than the support surface of the pallet. When the bars are transmitted through the saw cut, the support rollers are at a high position, and the top surface of the support rollers is slightly higher than the support surface of the pallet, allowing the bars to pass smoothly. On the other hand, before the bars are transmitted to the cutting position, the cutting size must be determined first. The length-setting baffle of the length-setting machine is lowered in advance. The front ends of multiple bars travel to the length-setting baffle and then stop. Then, the support rollers before and after sawing are controlled to descend. The bars descend with the support rollers until they contact the top surface of the pallet and then stop. The pallet and the support rollers jointly support multiple bars. Then, the first positioning component and the second positioning component are controlled to work, clamping the bars in the horizontal direction and pressing them in the vertical direction. After that, the cutting saw begins to advance and cut, and the length-setting baffle rises synchronously. After sawing, the bar is clamped horizontally and retracted, then clamped vertically and raised. The support rollers before and after sawing rise, completing one sawing cycle. During the cutting process, the two support parts provide stable support for the bar. The first and second positioning components work together with the support parts to fix the bar in place, ensuring cutting quality and resulting in a smooth cut surface.

[0043] In particular, the support surface of the pallet plays an important role in supporting the bar stock. As the bar stock rubs against the support surface of the pallet during transportation, and the long-term contact and friction between the bar stock and the support surface of the pallet causes wear. When the wear reaches a certain level, a gap will appear between the bottom of the pallet and the bar stock. If the gap is too large, the bar stock will sink during cutting, resulting in an uneven cut surface and seriously affecting the cutting quality of the bar stock. Therefore, the pallet needs to be replaced regularly.

[0044] Compared to existing technologies that use bolts or pins for fixing, where high-temperature deformation from cutting and sawdust buildup can clog the connection holes, making bolt or pin removal difficult, this embodiment features a protruding locking part on the support plate and a locking groove on the support plate, or vice versa. The support plate and support plate are connected by the protruding locking part and the locking groove, facilitating disassembly. The locking groove is a continuous groove in the first direction, and the mating surface between the locking groove and the protruding locking part is large, preventing severe jamming due to slight deformation. This facilitates disassembly, and during disassembly, the protruding locking part is easily engaged. The connector and the slot are detached from each other, reducing the labor intensity of workers. During installation, the protruding connector is simply aligned with the slot and pressed tightly, making installation very convenient, saving time and effort, and also saving some operating space. When installing or removing the tray, both the horizontal and vertical positioning parts are adjusted to positions away from the tray, leaving as much operating space as possible around the tray to facilitate installation or removal. Therefore, in this embodiment, the connection between the tray and the tray base is stable, disassembly and installation are convenient, reducing the labor intensity of workers, and helping to reduce tray replacement time and improve work efficiency.

[0045] Specifically, such as Figure 2 As shown, in the above-mentioned fixture, the protrusion engagement portion includes a strip-shaped protrusion extending along the first direction, and the cross-section of the strip-shaped protrusion perpendicular to the first direction is rectangular; or, the protrusion engagement portion includes a plurality of protruding pillars spaced apart along the first direction, the protruding pillars can be cylindrical or cubic, as long as they are arranged in a straight line along the first direction.

[0046] For the engagement between the protruding locking part and the slot, a gap fit is provided between the protruding locking part and the slot in the second direction. The small gap between the protruding locking part and the slot in the second direction will not affect the fit between the protruding locking part and the slot. The engagement between the two can still be stable, and it makes it easier to install and remove the protruding part and the slot.

[0047] Preferably, the depth of the slot in the vertical direction can be set to be smaller than the height of the protruding latching part in the vertical direction, and slightly smaller. For example, in the vertical direction, the depth of the slot is 0.5 mm to 2 mm smaller than the protruding latching part.

[0048] In one possible implementation, for the structural configuration of the tray, the tray 12 can be a single-piece tray 12, or, refer to... Figure 1As shown, the pallet 12 is configured as a split structure, comprising at least two sub-pallets 12 distributed along a first direction. Adjacent sub-pallets 12 are connected in contact. Since the pallet 12 is made of steel and is relatively heavy, configuring it as a split structure with the sub-pallets 12 arranged and spliced ​​along the first direction allows for individual disassembly or assembly of the sub-pallets 12 during installation and disassembly. This reduces the weight required for each installation or disassembly by the worker, thus reducing labor intensity and ensuring work safety. For example, the pallet 12 can be formed by splicing three sub-pallets 12, further reducing the weight the worker needs to lift each time during disassembly or installation.

[0049] Specifically, a groove is provided on the end face of the tray 12 along the first direction. When the slot is provided on the tray 12, the groove avoids the opening of the slot on the end face. During disassembly, in order to make it easier to remove the tray 12, a pry bar can be used to pry the tray 12 upwards in conjunction with the groove to loosen the tray 12 and make it easier to disassemble.

[0050] To limit the pallet's movement in the first direction, such as Figure 1 As shown, each pallet seat 11 has a limiting boss 4 at both ends in the first direction. The limiting boss 4 is used to limit the pallet 12 in the first direction. In the first direction, the pallet 12 is located between the two limiting bosses 4, and in the vertical direction, there is an overlapping part between the limiting boss 4 and the pallet 12, so that there is a contact part between the end face of the pallet 12 in the first direction and the limiting boss 4, so that the limiting boss 4 can abut against the pallet 12 at both ends, ensuring that the pallet 12 does not move in the first direction during cutting.

[0051] Specifically, the aforementioned limiting boss and the pallet seat are integrated into one structure, which has good structural integrity and is sturdy; or, the limiting boss can also be welded to the pallet seat, which is convenient for manufacturing.

[0052] In the fixture of the aforementioned sawing equipment, the setting of the first positioning component is specifically referred to... Figure 2 and Figure 3As shown, the first positioning component 2 includes: a guide rail 22, a push block, a first driving device, and a limiting baffle 23. Two guide rails 22 are provided, each extending along a first direction. The two guide rails 22 are arranged in parallel along a second direction, and are respectively located on the outer sides of the two support portions 1 in the second direction. Two push blocks are provided, each corresponding to one of the two guide rails 22. One push block is provided on each guide rail 22, and the corresponding push blocks slide in cooperation with the guide rails 22. The push blocks can move along the first direction on the guide rails 22, and the push blocks constitute a horizontal positioning portion 2. 1; The first driving device is connected to the push block and is used to drive the push block to move along the guide rail 22; The first driving device may include a first power device, which is connected to two push blocks, and the two push blocks are powered by the same power device; or, the first driving device may also include two first power devices, and the first driving device may be a hydraulic cylinder, with the two hydraulic cylinders respectively connected to the two push blocks one by one, one hydraulic cylinder driving one push block to move, and the two push blocks are driven independently by two different power devices, but the two first power devices are linked to each other so that the two push blocks move in unison.

[0053] In addition, such as Figure 3 As shown, a limiting baffle 23 is disposed on the side of the pushing block facing the bar. The limiting baffle 23 is spaced apart from and opposite to the pushing block. The gap between the pushing block and the limiting baffle 23 is used for the transmission of the bar. In the first direction, there is a gap between the pushing block and the limiting baffle 23, and the transmission channel of the bar passes through this gap. The transmission channel of the bar extends along the second direction, and the support part 1 is located at a set position in the middle of the transmission channel. The cutting route A extends along the first direction. Between the two support parts 1, the bar is transmitted from one side of the cutting route A and passes through the other side of the cutting route A. At the cutting point, one side of the cutting route A is the transmission inlet side of the bar, and the other side is the transmission outlet side. Specifically, in the transmission direction of the bar, a limiting baffle 23 is disposed on the transmission inlet side of the cutting point, and a limiting baffle 23 is also disposed on the outlet side of the cutting point. The limiting baffle 23 is used to block the bar in the first direction. When the pusher moves toward the bar and pushes multiple bars toward the limiting baffle 23, the limiting baffle 23 acts as a limit, so that multiple bars can be pressed together in the first direction and the multiple bars are clamped between the pusher and the limiting baffle.

[0054] Alternatively, a pressure sensor can be installed on the side of the limiting baffle 23 facing the bar, or on the side of the push block facing the bar. The pressure sensor is used to contact the bar and detect the pressure of the bar being pressed in the first direction. When the pressure detected by the pressure sensor reaches the set value, the push block stops pushing, pressing multiple bars together to facilitate stable cutting, ensure the quality of the cut surface, and prevent the push block from advancing too far and stacking the bars too tightly, thus avoiding damage to the bars.

[0055] To prevent the bar stock from being over-clamped, the pressure of the hydraulic cylinder driving the push block can be set. When the hydraulic cylinder reaches its preset pressure value, it stops moving. This is considered to be the time when the bar stock is properly clamped, thus avoiding excessive pressure on the bar stock.

[0056] In addition, the first positioning component also includes a first linear sensor, which is used to detect the total width of the multiple bars stacked in a first direction.

[0057] In one possible implementation, refer to Figure 1 and Figure 2 As shown, the second positioning component 3 in this embodiment includes: a clamping block, a vertical rail, and a second driving device. Two clamping blocks are provided, extending along a first direction and located on opposite sides of the cutting path A. The two clamping blocks are located on the side of the pallet 12 away from the pallet seat 11, and are positioned above the pallet 12. A vertical rail is provided corresponding to each of the two clamping blocks, with each clamping block corresponding to a vertical rail. The vertical rail extends along a third direction. In the corresponding clamping blocks and vertical rails, the clamping blocks are movably mounted on the vertical rails along a third direction via a connecting frame, clamping... The block constitutes a vertical positioning part 31; specifically, each pressing block is provided with two vertical rails. In the corresponding pressing blocks and vertical rails, the two vertical rails can be set below the bracket seat. The two vertical rails can be arranged along the first direction. A connecting frame is provided at each end of the pressing block in the first direction. One end of the connecting frame is fixedly connected to the pressing block, and the other end of the connecting frame is connected to the vertical rail. For example, a slider is provided on the vertical rail. The other end of the connecting frame is connected to the slider on the vertical rail. The slider can be slidably connected to the vertical rail and can move up and down along the vertical rail.

[0058] The second driving device can drive the clamping blocks to move. Specifically, the second driving device is connected to the slider and can drive the slider to move up and down. For example, the second driving device may include one second power device, and the sliders corresponding to the two clamping blocks are driven by the same second power device; or, the second driving device includes two second power devices, which can be hydraulic cylinders, with one hydraulic cylinder corresponding to each clamping block. The two clamping blocks are driven by two different hydraulic cylinders and can be driven independently. However, the two second power devices can be linked to keep the movements of the two clamping blocks consistent.

[0059] Specifically, a pressure sensor is provided on the side of the clamping block facing the bar. This pressure sensor can contact the bar and detect the downward pressure of the clamping block on the bar. This pressure sensor can be a longitudinal pressure sensor. When the pressure value of the longitudinal pressure sensor reaches a preset value, the clamping block stops pressing down, so that the clamping block can clamp the bar without excessive pressure, thus avoiding damage to the bar.

[0060] In addition, the second positioning component mentioned above also includes a second linear sensor, which can detect the diameter of the bar and can predict the downward movement distance of the clamping block in advance.

[0061] Continue to refer to Figure 2 As shown, the two clamping blocks can be set one-to-one with the two pallets 12. The clamping blocks and the pallets 12 are vertically opposite each other. When installing the pallet 12, after aligning the pallet 12 with the pallet seat 11, the clamping blocks can be used to press down to press the pallet 12 onto the pallet seat 11, saving manpower and reducing the labor intensity of workers.

[0062] Based on the same design concept, this embodiment also provides a sawing device, specifically including a frame, a cutting saw, and a fixture as described in any of the sawing devices provided in the above embodiments. The frame has a cutting station, a fixture is provided at the cutting station, and a cutting path is provided at the cutting station. The cutting saw can move along the cutting path to cut the bar. For example, the cutting saw can be an abrasive wheel saw.

[0063] Specifically, the cutting saw is adjustable in both the vertical and first directions. For example, the cutting saw is mounted on a third drive unit, which drives the cutting saw to move vertically. The third drive unit and the cutting saw are mounted on a fourth drive unit. The fourth drive unit includes a fixed base fixed to a support plate base, extending along the first direction. A slide is mounted on the fixed base, slidably connected to the fixed base, and capable of moving along the first direction. The cutting saw is fixedly mounted on the slide. More specifically, the fourth drive unit also includes a motor, which is driven by a ball screw to move the slide; or, the fourth drive unit includes a hydraulic cylinder, whose piston rod is driven by the slide to move the slide.

[0064] Preferably, the cutting device described above is further equipped with a grating for detecting the diameter of the saw blade. The grating can detect the edge of the saw blade. During the cutting process, after the saw has finished cutting the bar, it is driven to rise, then moves backward along a first direction. When it returns to the initial position, it is driven to fall again until the grating detects the saw blade. Since the saw blade will wear during the cutting process, using a grating to detect the saw blade allows the acquisition of the latest diameter data of the saw blade, enabling data compensation for the next cut, so that the saw can move to the appropriate position for cutting and ensure cutting accuracy.

[0065] In the second direction, there is a transmission channel for transporting bar stock, and the cutting station is located at a set position in the middle of the transmission channel. Transmission components for transporting bar stock are provided on both sides of the cutting station. In the direction of extension of the transmission channel and in front of the bar stock, a length-fixing machine is provided. The length-fixing machine includes a fixed beam and a movable beam. The movable beam is movably mounted on the fixed beam in the second direction and can move back and forth in the second direction. A lifting baffle is provided on the movable beam. The lifting baffle is opposite to the front end of the bar stock. The position of the lifting baffle in the second direction is adjustable to adjust the cutting length of the bar stock. The lifting baffle is also adjustable in the third direction to facilitate the transportation of the bar stock after cutting.

[0066] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
