Description

Technical Field

[0001] This invention relates to the field of cutting machines, and more particularly to a precision cutting machine for metal materials. Background Technology

[0002] A cutting machine is a common type of machinery used in metal processing to cut materials.

[0003] In order to improve cutting efficiency, current cutting machines usually place multiple bars of the same size side by side on the frame when cutting bar stock. Then, the bar stock is pushed to the cutting mechanism by the pushing mechanism. The cutting machine moves along the arrangement direction of the multiple bars and cuts the bar stock by the saw blade. When a cutting machine cuts multiple bars, to avoid unevenness in the cut surface due to bar tension, clamping mechanisms are usually installed on both sides of the cutting machine to improve the flatness of the cut surface. Furthermore, to prevent interference between the cutting machine and the cut bar surface when the machine resets after cutting, a channel larger than the cutting thickness needs to be reserved between the cut portion and the remaining portion. However, in traditional operation, the two clamping mechanisms on both sides of the cutting machine are independent, and both vertical clamping and horizontal separation of the bars require at least one cylinder. Therefore, the entire clamping and separation process requires at least four cylinders (two on each side of the cutting machine), increasing equipment costs. Meanwhile, when the radial length of the working part of the saw blade of the cutting machine is greater than the sum of the diameters of multiple bars, after the saw blade cuts the first bar, when the saw blade cuts the next bar, the bar will fall between the saw blade and the cut surface of the bar. This causes the saw blade to continuously rub against the plane of the cut bar, and the friction time is the longest for the first bar cut, decreasing sequentially along the direction of the last bar cut. As a result, when multiple bars are arranged and cut in sequence, vibrations are very likely to occur when the uncut bars initially contact the cutter head. Since the cut bars have already been cut, their clamping relies entirely on clamping and fixing on one side, making them susceptible to slight displacement, resulting in contact friction with the cutter head. This is not only detrimental to the safe operation of the cutter head, but also affects the cross-sectional accuracy of the cut bars, thereby reducing the cutting precision of the cutting machine.

[0004] Furthermore, during this process, the friction between the cut bar and the saw blade over a long period of time will exacerbate the wear of the saw blade and shorten its service life. At the same time, when the saw blade wears to different degrees, the thickness of the saw blade changes at different locations, causing the high-speed rotating saw blade to become unstable, which will also affect the precision of the cutting machine in cutting metal bars. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of reduced saw blade lifespan due to varying degrees of wear between the cut metal material and the saw blade, decreased precision due to varying degrees of wear between the cut metal material and the saw blade, and high cost due to the need for multiple cylinders to clamp the metal material. Therefore, a precision metal material cutting machine is proposed.

[0006] To achieve the above objectives, the present invention employs the following technical solution: It includes a frame and a cutting mechanism and a pushing mechanism installed within the frame. The cutting mechanism includes a cutting machine that slides radially along the bar stock, and further includes... A clamping mechanism, comprising a gantry frame fixed on a machine frame, wherein a liftable lifting frame is mounted on the gantry frame; The bottom of the lifting frame is equipped with multiple short pressure plates that slide perpendicularly to the direction of movement of the cutting machine, and multiple short pressure plates are provided on both sides of the cutting machine. A separation ramp is fixed on the short pressure plate, and a driving ramp for driving the separation ramp to separate is fixedly connected to the cutting machine; The self-locking mechanism includes a hook plate that is elastically and movably connected to the bottom of the lifting frame and a reset pressure rod fixed to the gantry frame; The pushing mechanism pushes the bar stock to the position of the cutting machine. The short pressure plate is lowered by the lifting frame and presses on the bar stock. The bar stock is cut by the linear moving cutting machine. After cutting, the two short pressure plates of the bar stock are separated by the extrusion of the driving ramp, so that the two sections of the bar stock are separated. At the same time, the hook plate hooks the separation ramp. After multiple bars are cut, the hook plate rises with the lifting frame and is pressed against the reset pressure bar before disengaging from the separation ramp to complete the reset. The long pressure plate is fixedly connected to an alignment mechanism for adjusting the alignment of the bar cutting surfaces.

[0007] As a further description of the above technical solution: a pressing cylinder is fixed on the gantry frame, and the piston rod of the pressing cylinder is fixedly connected to the lifting frame; The bottom of the lifting frame is fixed with two long pressure plates placed on both sides of the cutting machine; The bottom of the long pressure plate is fixed with multiple second guide rails, and a second slider that is fixedly connected to the separation slope block and the short pressure plate slides on the second guide rails.

[0008] As a further description of the above technical solution: the cutting mechanism includes a first guide rail fixed on the frame, a first slider slidably mounted on the first guide rail, and the cutting machine fixed on the first slider; The first slider and the first guide rail are connected by a propulsion cylinder; The driving ramp is fixedly connected to the first slider via a fixing frame; The distance between the two separated bar sections is greater than the width of the fixing frame.

[0009] As a further description of the above technical solution: the fixing frame is arranged around the cutting blade of the cutting machine, the fixing frame is a tubular structure, and multiple adsorption holes are opened on the side of the fixing frame near the cutting blade of the cutting machine. The bottom of the fixing frame is connected to a corrugated hose that is connected to the adsorption device.

[0010] As a further description of the above technical solution: the long pressure plate is provided with multiple slides, and a second slider is slidably installed in each slide. The outer side of the second slider is fixedly installed with a locking strip that corresponds to and matches the hook plate. The outer side of the second slider is connected to the inner wall of the slide rail by a return spring; The inner wall of the slide is symmetrically fixed with shafts, and the lower surface of the hook plate is symmetrically fixed with a shaft seat that is rotatably connected to the shaft. The side of the hook plate away from the locking strip is fixedly connected to the long pressure plate by a support spring.

[0011] As a further description of the above technical solution: a rubber pad is fixed on the lower surface of the short pressure plate, and a groove adapted to the bar stock is opened on the lower surface of the rubber pad.

[0012] As a further description of the above technical solution: a limiting block is fixed on the inner wall of the slide and placed above the hook plate, the limiting block being placed on the outside of the shaft.

[0013] As a further description of the above technical solution: the outer side of the long pressure plate is a sloping structure, the support spring is placed on the sloping side of the long pressure plate, and the reset pressure rod is placed above the sloping surface of the long pressure plate.

[0014] As a further description of the above technical solution: the pushing mechanism includes a cylinder and a pressure plate. A long rubber pad is fixed on the lower surface of the pressure plate. The long rubber pad has a groove that matches the outer diameter of the bar. Multiple support rollers are rotatably arranged on the frame.

[0015] As a further description of the above technical solution: the alignment mechanism includes support arms symmetrically fixed on the long pressure plate and alignment roller shafts rotatably connected to the two support arms, and the bottoms of the two support arms are fixed by reinforcing rods.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This application, after the bar stock is cut by the cutting machine, immediately pushes the separation block to move the short pressure plate holding the cut material apart, separating the cut bar stock segment from the high-speed saw blade. This avoids saw blade wear caused by continuous friction between the cut surface and the rotating saw blade, thus extending the saw blade life. At the same time, it solves the problem that during continuous bar stock cutting, the force of the uncut material may cause slight displacement of adjacent cut material, resulting in frictional wear and inaccurate cross-sectional accuracy due to contact with the cutter head. This avoids potential hazards and improves safety.

[0017] 2. This application reduces the number of cylinders used to clamp and separate the bar stock from four to one by using a single-cylinder drive method for the pressing cylinder, thereby reducing equipment costs.

[0018] 3. This application effectively prevents the short pressure plate from accidentally resetting and sliding due to equipment vibration or external interference through a self-locking mechanism, ensuring stable separation. When the lifting frame resets and rises, the reset lever automatically presses against the outer end of the hook plate, causing it to rotate and lift against the support spring force, thereby automatically unlocking the locking bar. The short pressure plate automatically resets to its initial clamping position under the action of the reset spring. The entire process requires no additional operation, ensuring smooth and reliable cyclic operation.

[0019] 4. In this application, the mounting bracket covers the suction holes in the key areas of the saw blade and is connected to an industrial vacuum cleaner via a corrugated hose, which minimizes debris splashing and accumulation, significantly improves the cleanliness of the workbench, and enhances the operating environment.

[0020] 5. By setting up an alignment mechanism, this application allows the alignment mechanism to adjust the cut surfaces of the bar stock after each cutting operation, so as to avoid small length differences that could affect the cutting accuracy. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] like Figure 1 - Figure 12 As shown, the present invention provides a precision metal material cutting machine, including a frame 10 and a cutting mechanism 20 and a pushing mechanism 50 installed within the frame 10. The cutting mechanism 20 includes a cutting machine 21 that slides radially along the bar stock. Multiple bars stock are arranged on the frame 10, and then, under the action of a high-speed rotating saw blade, the radially sliding cutting machine 21 sequentially cuts the arranged bars stock. The machine also includes... The clamping mechanism 30 includes a gantry frame 31 fixed to the frame 10 and positioned above the saw blade of the cutting machine 21, and a liftable lifting frame 33 is installed on the gantry frame 31. The bottom of the lifting frame 33 is equipped with multiple short pressure plates 35 that slide perpendicularly to the direction of movement of the cutting machine 21. Multiple short pressure plates 35 are provided on both sides of the cutting machine 21. The short pressure plates 35 on both sides are symmetrically distributed with respect to the saw blade of the cutting machine 21. Each pair of symmetrically arranged short pressure plates 35 is used to press down a bar. Thus, each pair of short pressure plates 35 can independently clamp a bar by cooperating with the frame 10. A separation ramp 362 is fixed on the short pressure plate 35 and slides on the gantry frame 31. The sliding direction of the separation ramp 362 is parallel to the conveying direction of the bar stock. The side of the separation ramp 362 closest to the cutting machine 21 is an inclined surface that is inclined towards the saw blade. At the same time, a driving ramp 38 for driving the separation ramp 362 to separate is fixedly connected on the cutting machine 21. The outer plane of the driving ramp 38 meets the inclined surface of the separation ramp 362. It is worth noting that when the drive ramp 38 and the separation ramp 362 are in contact, the saw blade completes the cutting of the corresponding bar material. This avoids the axial force generated on the bar material due to the drive ramp 38 driving the separation ramp 362 in advance during the saw blade cutting process, and ultimately avoids the problem of uneven cut surface of the bar material caused by the axial force during the cutting process. After the bar stock is completely cut, the drive ramp 38 moves with the cutter 21. The contact surface of the drive ramp 38 acts on the inclined surface of the separation ramp 362, causing the separation ramp 362 to drive the two short pressure plates 35 acting on the cut bar stock to separate, thereby separating the cut bar stock and avoiding continuous friction between the bar stock cut surface and the saw blade. The self-locking mechanism 40 includes a hook plate 41 that is elastically and movably connected to the bottom of the lifting frame 33 and a reset pressure rod 43 fixed on the gantry frame 31. A hook plate 41 is provided on the outer side of each short pressure plate 35, and a reset pressure rod 43 is fixed on both sides of the gantry frame 31. The reset pressure rod 43 is arranged along the arrangement direction of multiple hook plates 41 on both sides of the saw blade. After the drive ramp 38 separates the cut bar stock, the two separate ramps 362 are hung on their corresponding hook plates 41 to prevent the separation ramps 362 from sliding relative to each other due to vibrations generated during equipment operation. The pushing mechanism 50 pushes the bar stock to the position of the cutting machine 21. The short pressure plate 35 is lowered by the lifting frame 33 and presses on the bar stock. The cylinder of the pushing mechanism 50 retracts to ensure the normal axial sliding of the bar stock. The bar stock is cut by the linear moving cutting machine 21. After cutting, the two short pressure plates 35 of the bar stock are separated by the extrusion of the driving ramp 38, so that the two sections of the bar stock are separated. At the same time, the hook plate 41 hooks the separation ramp 362 to prevent the separation ramp 362 from sliding relative to each other after separation. After multiple bars are cut, the cutting machine 21 linearly slides back to its original position. Then, the hook plate 41 rises with the lifting frame 33 and presses against the reset pressure bar 43 before disengaging from the separation ramp 362 to complete the reset. Each time the cutting machine 21 cuts a bar, it can drive the drive ramp 38 to separate the bar from the separation ramp 362 and the bar under the short pressure plate 35. This avoids saw blade wear caused by continuous friction between the bar's cut surface and the saw blade, and also avoids the problem of inconsistent lengths caused by different degrees of wear on the bar's cut surface. At the same time, the clamping of the bar and the separation of the cut bar can be achieved by the single drive of the lifting frame 33, thereby reducing equipment costs. like Figure 4 , Figure 12 As shown, the long pressure plate 34 is fixedly connected to an alignment mechanism 60 for adjusting the alignment of the cutting surfaces of the bar stock. After the bar stock is cut, the alignment mechanism 60 rises with the long pressure plate 34 and passes the cutting surface position of the bar stock. The alignment mechanism 60 makes the cutting surfaces of the bar stock in a state of common alignment, thereby ensuring that the length of the bar stock is the same when it is conveyed, avoiding the problem that the cutting surfaces of the bar stock are not on the same plane due to the deflection of the saw blade, and thus improving the cutting accuracy.

[0025] like Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, a vertically arranged pressing cylinder 32 is fixed on the gantry frame 31. The cylinder body of the pressing cylinder 32 is fixed on the crossbeam of the gantry frame 31, and the piston rod passes through the crossbeam. The piston rod of the pressing cylinder 32 is fixedly connected to the lifting frame 33 by a bolt and nut assembly. Two long pressure plates 34 are fixed at the bottom of the lifting frame 33 and placed on both sides of the cutting machine 21. The two long pressure plates 34 are symmetrically arranged on both sides of the saw blade. The bottom of the long pressure plate 34 is fixed with a plurality of second guide rails 341 arranged perpendicular to the moving direction of the cutting machine 21. The second guide rails 341 are equipped with second sliders 36 that are fixedly connected to the separation ramp 362 and the short pressure plate 35. The separation ramp 362 and the short pressure plate 35 are connected by the second sliders 36. At the same time, the sliding cooperation between the second sliders 36 and the second guide rails 341 ensures the stability of the short pressure plate 35 when it slides.

[0026] like Figure 2 , Figure 5 , Figure 6 As shown, the cutting mechanism 20 includes a first guide rail 23 fixed on the frame 10. The first guide rail 23 is perpendicular to the second guide rail 341. A first slider 22 is slidably mounted on the first guide rail 23. The body of the cutting machine 21 is fixed on the first slider 22. The first slider 22 and the first guide rail 23 are connected by a push cylinder 24. The extension and retraction direction of the push cylinder 24 is parallel to the first guide rail 23. The cylinder body of the push cylinder 24 is fixedly connected to the frame 10, and the piston rod is fixedly connected to the first slider 22. Thus, the linear movement of the cutting machine 21 is achieved by the extension and retraction of the push cylinder 24. The driving ramp 38 is fixedly connected to the first slider 22 via the fixing bracket 39; Furthermore, the distance between the cut surfaces of the two separated bar sections is greater than the width of the fixed frame 39 to ensure the normal movement of the fixed frame 39, which in turn drives the cutting machine 21 and the driving ramp 38 to move through the first slider 22.

[0027] like Figure 2 , Figure 5 , Figure 6 The fixing frame 39 is arranged around the cutting blade of the cutting machine 21, and the fixing frame 39 is located on the opposite side of the cutting side of the cutting machine 21. The horizontal tube of the fixing frame 39 is placed directly above the saw blade and is connected to the vertical tube. Since the fixing frame 39 is a tubular structure, multiple suction holes 391 are opened on the side of the fixing frame 39 near the cutting blade of the cutting machine 21, that is, suction holes 391 are opened on the side of the vertical tube near the saw blade and the bottom of the horizontal tube. The bottom of the fixing frame 39 is connected to a corrugated hose 392 connected to the suction device, which includes an industrial vacuum cleaner (not shown in the figure). The corrugated hose 392 is fixedly connected to the suction pipe of the industrial vacuum cleaner. When the saw blade is running at high speed, the metal debris during the cutting process passes through the suction holes 391 opened on the fixing frame 39 and is sucked into the industrial vacuum cleaner through the corrugated hose 392. Since the adsorption holes 391 cover the sides and top of the saw blade, they can adsorb debris during the cutting process to the greatest extent, thus ensuring the cleanliness of the workbench.

[0028] like Figure 3 , Figure 8 , Figure 9 , Figure 10 As shown, the long pressure plate 34 has multiple slides 342, and a second slider 36 slides in each slide 342. That is, the second slider 36 passes through the slide 342. The outer side of the second slider 36 is fixedly installed with a locking strip 361 that corresponds to and matches the hook plate 41. The hook plate 41 includes a plate body and a hook head, and the side of the hook head near the locking strip 361 has a sloping structure. The outer side of the second slider 36 is connected to the inner wall of the slide 342 by a return spring 37, so that when the locking strip 361 is disengaged from the hook plate 41, the elastic rebound of the return spring 37 will reset the second slider 36 and the short pressure plate 35. A shaft 343 is symmetrically fixed to the inner wall of the slide 342. A bearing seat 411 rotatably connected to the shaft 343 is symmetrically fixed to the lower surface of the hook plate 41. Through the cooperation between the bearing seat 411 and the shaft 343, the hook plate 41 can rotate around the shaft 343. The side of the hook plate 41 away from the locking strip 361 is fixedly connected to the long pressure plate 34 through the support spring 42. When the second slider 36 slides towards the hook plate 41, the locking strip 361 presses the hook plate 41 to lift it through the slope of the hook head and compresses the support spring 42. When the hook head is placed inside the locking strip 361, the support spring 42 elastically rebounds, so that the hook plate 41 hangs on the locking strip 361, thereby fixing the short pressure plate 35 on the self-locking mechanism 40. It is worth noting that, in order to prevent debris from falling into the slide 342 during the cutting operation, accordion covers (not shown in the figure) are fixedly connected to both sides of the second slider 36 and the slide 342.

[0029] like Figure 4 , Figure 10 As shown, a rubber pad 351 is fixed on the lower surface of the short pressure plate 35. The lower surface of the rubber pad 351 is provided with a groove that is adapted to the bar stock. By using the rubber pad 351 and the groove on the lower surface that is adapted to the outer surface of the bar stock, the contact area with the bar stock is increased, thereby increasing the friction coefficient between the short pressure plate 35 and the bar stock, so as to ensure the effect of the short pressure plate 35 in pushing the bar stock.

[0030] like Figure 4 , Figure 8 As shown, a limiting block 344 is fixed on the inner wall of the slide 342 and placed above the hook plate 41. The limiting block 344 is placed on the outside of the shaft 343. The limiting block 344 is set to avoid the hook head of the hook plate 41 from tilting downward due to the excessive support of the support spring 42, thereby ensuring that the locking strip 361 can always correspond to the slope of the hook head.

[0031] like Figure 4 , Figure 8 As shown, the outer side of the long pressure plate 34 is a sloping structure. The support spring 42 is placed on the sloping side of the long pressure plate 34, and the reset pressure rod 43 is placed above the sloping surface of the long pressure plate 34. That is, when the hook plate 41 abuts against the limiting block 344, the part of the hook plate 41 on the sloping side of the long pressure plate 34 protrudes out of the long pressure plate 34. Therefore, when the long pressure plate 34 rises, the protruding part of the hook plate 41 can be lifted and disengaged from the locking strip 361 by the pressure of the reset pressure rod 43.

[0032] like Figure 1As shown, the pushing mechanism 50 includes a cylinder and a pressure plate, as well as a linear module. The cylinder is fixed on the slider of the linear module by a bracket, and the pressure plate is fixed on the lower end of the piston rod. The extension of the piston rod of the cylinder clamps the bar on the frame 10 through the pressure plate, and the linear module drives the slider to move the bracket along the axis of the bar to realize the conveying of the bar. A long rubber pad is fixed on the lower surface of the pressure plate. The long rubber pad has a groove that matches the outer diameter of the bar to limit the bar and prevent the bar from rolling.

[0033] like Figure 1 As shown, multiple support rollers 11 are rotatably mounted on the frame 10, and the support rollers 11 are perpendicular to the bar stock. A support roller 11 is also mounted below each rubber pad 351. The bar stock is pressed between the short pressure plate 35 and the support rollers 11. When the short pressure plate 35 moves horizontally, the rotation of the support rollers 11 reduces the coefficient of friction between the bar stock and the frame 10, and the edge short pressure plate 35 pushes the bar stock to move horizontally.

[0034] like Figure 12 As shown, support arms 61 are symmetrically fixed on the inner side of the long pressure plate 34 near the pushing mechanism 50, and the bottom of the two support arms 61 are rotatably connected to the alignment roller shaft 62 through bearings. At the same time, the distance between the alignment roller shaft 62 and the long pressure plate 34 is greater than the outer diameter of the bar. Therefore, when the short pressure plate 35 presses on the bar, the alignment roller shaft 62 is positioned below the bar. After the cutting is completed and the short pressure plate 35 pushes the bar outward, the cut surface of the bar to be cut is within the radius of the alignment roller shaft 62. When the lifting frame 33 rises, the alignment roller shaft 62 starts to press the bar from the bottom of the bar's cut surface, making the cut surface of the bar fit with the alignment roller shaft 62. This completes the alignment of the cut surfaces of the bar to be cut, ensuring that the front cut surfaces are aligned after each push of the bar by the pushing mechanism 50. This ensures that the length of the cut bar is the same when cutting multiple bars simultaneously. Meanwhile, the lower ends of the two support arms 61 are fixed by reinforcing rods 63 to prevent the alignment roller 62 from being squeezed and bent. And when the alignment roller 62 is placed above the bar stock, the reset pressure bar 43 presses down on the hook plate 41. Meanwhile, to prevent the alignment roller 62 from causing collision damage to the cut surface, the outer wall of the alignment roller 62 is also wrapped with a silicone layer.

[0035] like Figure 6 As shown, a strip-shaped adsorption hole 391 is provided on the side of the fixed frame 39 near the pushing mechanism 50, and the adsorption hole 391 is close to the cut surface of the bar stock. When the fixed frame 39 moves horizontally, the adsorption hole 391 on the side adsorbs the debris on the cut surface of the bar stock to ensure the cleanliness of the cut surface, thereby avoiding the debris from affecting the alignment roller 62 to squeeze the cut surface of the bar stock, and finally ensuring the flatness of the aligned cut surfaces.

[0036] Working principle: The bar stock is placed on the support roller shaft 11 of the frame 10 and placed in the groove of each short pressure plate 35. The groove of each short pressure plate 35 corresponds to the groove of the long rubber pad. Then, the bar stock is clamped on the frame 10 by the extension of the cylinder piston rod through the pressure plate. The linear module drives the slider to move the support along the axis of the bar stock to realize the conveying of the bar stock. In this state, the reset pressure rod 43 presses against the upper surface of the outer end of the hook plate 41. At this time, the short pressure plates 35 on both sides of the cutting machine 21 approach each other. Then the piston rod of the pressing cylinder extends and causes the lifting frame 33 to descend, so that the bar is fixed on the frame 10 by the short pressure plate 35 and the rubber pad 351 below it. At the same time, the cylinder piston rod of the pushing mechanism 50 retracts, and the pressure plate does not squeeze the bar, but the bar is still placed in the groove. Then the cutting mechanism 20 is started, the saw blade of the cutting machine 21 rotates at high speed, and at the same time the push cylinder 24 pushes the cutting machine 21 and the fixed frame 39 to move horizontally. After the saw blade cuts a bar, the drive block 38 begins to squeeze the separation block 362 and hangs the clip 361 on the separation block 362 on the hook plate 41. At the same time, the return spring 37 is compressed until all the bars are cut off. Then the cutting machine 21 is reset by the push cylinder 24. The moving fixed frame 39 allows the debris from the saw blade and the cut side of the bar to be sucked into the industrial vacuum cleaner through the suction hole 391, ensuring the cleanliness of the workbench and the cut side of the bar. Then the pressing cylinder 32 retracts. When the lifting frame 33 rises, the alignment roller 62 starts to squeeze the bar from the bottom of the bar's cut surface, making the cut surface of the bar fit with the alignment roller 62, thus completing the alignment process of the cut surface of the bar to be cut. Then, the hook plate 41 is pressed down by the reset pressure rod 43 to disengage the hook head from the clamping strip 361, so that the short pressure plate 35 can be reset. When cutting the material again, first lower the lifting frame 33 so that the alignment roller 62 is placed below the bar and the rubber pad 351 is above the bar. Then, after the bar is pushed by the pushing mechanism 50, the short pressure plate 35 is pressed on the bar by the extension of the pressing cylinder 32. Finally, repeating the above steps will allow you to cut the bar stock again.
