Description

Technical Field

[0001] The present application relates to the field of cutting machines, and in particular to a cutting device for forging bars. Background Art

[0002] Forging bars typically require cutting during the actual processing process. Existing forging manufacturers typically use electric saws to cut the bars, due to the wide variety of diameters they produce. During the actual processing, the bar is pre-fixed on a rack on the side of the saw, and then the saw is pressed down to cut the bar.

[0003] It is known that when determining whether a chainsaw can cut bar stock, for ease of processing, the bar stock diameter needs to be smaller than the radius of the chainsaw's cutting blade. This allows the bar stock to be fixed on a stand so that it can be cut without flipping. Otherwise, due to the large diameter of the bar stock, the cutting blade can only cut more than half of the bar stock before interfering with the saw blade. To address this issue, manufacturers do not want to invest too much, so for some bars with diameters larger than the saw blade's radius, they can flip the bar stock to cut the entire bar stock. Typically, after cutting a portion of the fixed bar stock, the bar stock fixing device is removed, and the bar stock is manually flipped so that the uncut side is facing the saw blade. The bar stock is then fixed and cut again.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the above-mentioned cutting method is time-consuming and labor-intensive. Summary of the Invention

[0005] In order to improve processing efficiency and reduce the steps of manual disassembly and assembly of bars, the present application provides a cutting device for forging bars.

[0006] The present application provides a cutting device for forging bars, which adopts the following technical solution:

[0007] A cutting device for forging bars, comprising a machine table, a mounting frame provided above the machine table, a cutting assembly provided on the mounting frame, support frames for supporting the two ends of the bar material provided at both ends of the machine table, a first clamping plate provided on the machine table, a second clamping plate slidably provided on the machine table for use in conjunction with the first clamping plate, flipping assemblies evenly spaced apart on the second clamping plate, a driving assembly for driving the second clamping plate to slide provided on the side of the second clamping plate away from the first clamping plate, and when the driving assembly drives the second clamping plate to slide to a specified position, it can drive several flipping assemblies to operate, thereby causing the bar material clamped between the first clamping plate and the second clamping plate to rotate around its own axis.

[0008] By adopting the above technical solution, the rod is pre-placed on the support frame so that the rod is supported on the machine table. A socket for inserting the first splint is provided on the machine table. The first splint is inserted into the appropriate socket according to the diameter of the rod, and then the second splint is driven to move toward the first splint through the driving component until the inner side of the second plate fits against the side wall of the rod. After a gap is cut out in advance by the cutting component, since the diameter of the rod is greater than the radius of the saw blade, the driving component is controlled to continue driving at this time, but the second splint stops moving and stays at this position to drive the flipping component to operate, so that the rod is flipped. After the flipping is completed, the driving component is stopped, and the cutting component continues to cut, thereby realizing cutting of the rod.

[0009] Optionally, the driving assembly includes a screw fixed on the machine platform, a mounting base sliding on the machine platform, a double-axis motor fixedly mounted on the mounting base, a first gear coaxially fixed on the rotating shaft of the double-axis motor away from the second clamping plate, a second gear rotatably connected to the mounting base, and a synchronous belt wound around the first gear and the second gear. The second gear is coaxially arranged with the screw and threadedly connected. The screw is provided with a stop assembly near the end of the first clamping plate to drive the mounting base to stop sliding.

[0010] By adopting the above technical solution, in the process of controlling the rotation of the shaft of the double-axis extension motor through the PLC device, the first gear drives the second gear to rotate under the action of the synchronous belt, so that under the action of the thread driving force, the mounting seat and the second gear move along the axial direction of the screw. After the first clamping plate and the second clamping plate clamp the bar material, the mounting seat slides to the position of the stop assembly, making it difficult for the mounting seat to continue to move toward the first clamping plate, thereby facilitating the mounting seat to stay in the corresponding position to drive the flip assembly to operate.

[0011] Optionally, the mounting seat is hollow, the lead screw passes through the mounting seat and is slidably connected to the mounting seat, a mounting groove is opened on the upper surface of the machine, the mounting seat slides in the mounting groove, and the lead screw is fixed in the mounting groove.

[0012] By adopting the above technical solution, the sliding of the mounting seat is made more stable, and the lead screw is located in the mounting groove, thereby improving the simplicity of the entire workbench surface.

[0013] Optionally, the stop assembly includes a light rod arranged at one end of the screw near the first clamping plate, an abutment block sliding on the machine table, and a spring arranged between the machine table and the abutment block. When the mounting seat slides to the light rod position, the abutment block abuts against the side wall of the mounting seat under the action of the spring.

[0014] By adopting the above technical solution, when the mounting seat slides to the position of the polished rod, since there is no thread driving it, even if the second gear rotates, the mounting seat still stays at the position of the polished rod. At this time, the dual-axis motor shaft is continued to be driven to rotate, so that the flip belt is flipped without the mounting seat moving.

[0015] Optionally, the flipping assembly includes a first roller rotatably arranged on the upper side of the second clamping plate, a second roller rotatably connected to the lower side of the second clamping plate, and a flipping belt wound around the first roller and the second roller. The flipping belt is wound around the outer side of the second clamping plate. When the first clamping plate and the second clamping plate clamp the bar material, the flipping belt abuts against the outer side of the bar material. A transmission assembly for driving several first rollers to rotate is also provided between the second clamping plate and the first drive assembly.

[0016] By adopting the above technical solution, the transmission assembly drives the first rollers to rotate, so that the flipping belt is flipped and wound, and the bar clamped between the first clamping plate and the second clamping plate is flipped by the flipping belt.

[0017] Optionally, the transmission assembly includes a first rod coaxially connected to several first roller shafts, a worm gear coaxially fixed to the first rod, a second rod coaxially fixed to one end of the double-axle motor away from the first gear, a worm coaxially fixed to the second rod, and the worm gear is meshed with the worm gear.

[0018] By adopting the above technical solution, the second rod and the worm rotate synchronously, driving the worm wheel and the first rod to rotate synchronously, thereby driving the plurality of first rollers to rotate, realizing the flipping of the flipping belt.

[0019] Optionally, friction strips are evenly spaced apart on one side of the flipping belt that fits the bar.

[0020] By adopting the above technical solution, the friction strip increases the friction between the turning belt and the bar, making it easier to turn the bar.

[0021] Optionally, the cutting assembly includes an electric push cylinder fixed on a mounting frame, a connecting block fixed on the end of a piston rod of the electric push cylinder, a servo motor fixed on a side wall of the connecting block, and a cutting blade coaxially fixed on a rotating shaft of the servo motor.

[0022] By adopting the above technical solution, during the cutting process, the piston rod of the electric push cylinder is controlled by the PLC device to extend, so that the connecting block and the cutting disc move downward synchronously, thereby realizing the cutting of the bar material.

[0023] Optionally, the lead screw is formed by connecting a plurality of small lead screw segments to each other.

[0024] By adopting the above technical solution, since the diameter of the bar material will change, in order to control the stop position of the mounting seat, a small section of the lead screw at the end can be replaced with a smooth round rod to control the distance between the first clamping plate and the second clamping plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. After a slit is pre-cut by the cutting assembly, the bar stock is controlled to flip because its diameter is larger than the radius of the saw blade. After the flip is completed, cutting is continued, thereby achieving cutting of larger diameter bars. This process does not require removing the bar stock fixing device and manually flipping the bar stock, improving processing efficiency and reducing the number of manual bar disassembly and assembly steps.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a cutting device for forging bars.

[0035] Reference Figure 1, A cutting device for forged bar materials, including a machine table 1 and a mounting frame 2. The mounting frame 2 is in a U shape, and both ends of the mounting frame 2 are vertically downward and fixedly installed on the machine table 1. A cutting component 3 for cutting bar materials is provided on the mounting frame 2.

[0036] Refer to Figure 2 , The cutting component 3 includes an electric push cylinder 28, a connecting block 29, a servo motor 30 and a cutting blade 31. The electric push cylinder 28 is fixedly installed on the side wall of the mounting frame 2, and the piston rod of the electric push cylinder 28 is vertically downward. The connecting block 29 is fixedly installed at the end of the electric push cylinder 28. The servo motor 30 is fixedly installed on the side wall of the connecting block 29. The cutting blade 31 is coaxially fixedly installed on the rotating shaft of the servo motor 30.

[0037] Refer to Figure 3 , In order to make it difficult for the bar material to roll after being placed on the machine table 1, support frames 4 are provided at both ends of the machine table 1. The support frames 4 are in an arc shape and the opening is upward. At the same time, in order to clamp the bar material during cutting, a number of insertion holes for inserting the first clamping plate 5 are opened on the upper surface of the machine table 1, and a second clamping plate 6 cooperating with the first clamping plate 5 is slidably arranged on the machine table 1.

[0038] Refer to Figure 3 and Figure 4 , A driving component 8 for driving the second clamping plate 6 to slide is provided on the side of the second clamping plate 6 away from the first clamping plate 5. The driving component 8 includes a lead screw 9. In order to accurately control the distance between the first clamping plate 5 and the second clamping plate 6 and achieve adjustable control of the sliding distance of the second clamping plate 6, the lead screw 9 is set as several small segments connected to each other. Between adjacent two small segments of the lead screw 9, a slot is opened at one end and a protrusion is provided at the other end. The protrusion can be inserted and engaged in the slot. During actual disassembly and assembly, the user can pull it with the palm to achieve disassembly and assembly.

[0039] Refer to Figure 3 and Figure 5 , The driving component 8 further includes a mounting seat 10, a double-shaft extension motor 11, a first gear 12, a second gear 13 and a synchronous belt 14. In order to reduce the clutter on the tabletop of the machine table 1, a mounting groove 16 is opened on the tabletop of the machine table 1. The spliced lead screw 9 is fixedly installed in the mounting groove 16. The mounting seat 10 is hollow and the mounting seat 10 is slidably arranged in the mounting groove 16. The mounting seat 10 is fixedly connected to the second clamping plate 6. The lead screw 9 passes through the mounting seat 10, and the mounting seat 10 can slide along the axial direction of the lead screw 9, and the two do not interfere with each other.

[0040] Refer to Figure 3 and Figure 5The dual-axle motor 11 is fixedly mounted on the upper surface of the mounting base 10. The first gear 12 is rotatably connected to the upper surface of the mounting base 10 and is coaxially fixedly connected to one end of the rotating shaft of the dual-axle motor 11. The second gear 13 is rotatably connected to the inner cavity of the mounting base 10, and a through hole is formed on the rotating shaft of the second gear 13 and is threadedly connected to the lead screw 9. A synchronous belt 14 is wound around the first gear 12 and the second gear 13. The teeth of the synchronous belt 14 mesh with both the first gear 12 and the second gear 13, driving the first gear 12 to rotate. Under the action of the synchronous belt 14, the second gear 13 rotates synchronously. Under the action of the lead screw 9, the second gear 13 and the mounting base 10 slide synchronously along the axial direction of the lead screw 9.

[0041] Reference Figure 3 In order to flip the bar material after it is clamped, a number of flipping components 7 are evenly spaced on the second clamping plate 6. The flipping component 7 includes a first roller 20, a second roller 21 and a flipping belt 212. The first roller 20 is rotatably connected to the upper surface of the second clamping plate 6, and the second roller 21 is rotatably connected to the lower surface of the second clamping plate 6. The flipping belt 212 is wound around the first roller 20 and the second roller 21, so that the first roller 20 is driven to rotate to realize the winding movement of the flipping belt 212.

[0042] Reference Figure 3 and Figure 5 Several friction strips 27 are integrally formed on the sidewalls of the flipping belt 212. These friction strips 27 increase the friction between the flipping belt 212 and the bar, making it easier for the flipping belt 212 to drive the bar to rotate. When the first and second clamping plates 5 and 6 clamp the bar, the flipping belt 212 abuts the outside of the bar. To achieve synchronous operation of the multiple flipping belts 212, a transmission assembly 22 is provided on the second clamping plate 6.

[0043] Reference Figure 3 and Figure 5 The transmission assembly 22 includes a first rod 23, a worm gear 24, a second rod 25 and a worm 26. The first rod 23 is coaxially arranged with the first roller 20, and the rotating shafts of several first rollers 20 are fixedly connected to the first rod 23. The worm gear 24 is coaxially fixed on the side wall of the first rod 23. The second rod 25 is coaxially fixed to the end of the rotating shaft of the double-axis motor 11 away from the first gear 12. The worm 26 is coaxially fixed to the end of the second rod 25, and the worm 26 is engaged with the worm gear 24.

[0044] Reference Figure 3 and Figure 5When the mounting seat 10 moves, the flip belt 212 is flipped synchronously. In order to stop the mounting seat 10 from moving after it moves to the specified position, but at the same time the flip belt 212 can continue to move in a winding manner, a stop component 15 is provided at one end of the screw 9 near the first splint 5 to drive the mounting seat 10 to stop sliding.

[0045] Reference Figure 3 and Figure 5 The stop assembly 15 includes a polished rod 17, an abutment block 18 and a spring 19. The polished rod 17 has multiple different lengths. In the actual processing process, the polished rod 17 of the corresponding length is selected according to the needs, and one end of the polished rod 17 is inserted and installed in the card slot of the tail end screw 9, so that the polished rod 17 and the entire screw 9 are integrated. One end of the spring 19 is installed on the inner wall of the end of the mounting groove 16, and the other end is fixedly connected to the abutment block 18. When the mounting seat 10 slides to the position of the polished rod 17, the abutment block 18 abuts against the side wall of the mounting seat 10. At this time, the mounting seat 10 is in an immovable position.

[0046] The implementation principle of a cutting device for forging bars in an embodiment of the present application is as follows: the bar is placed on the support frame 4 in advance so that the bar is difficult to move on the machine table 1, and then the first clamping plate 5 is inserted into the corresponding plug-in hole, and then the number of small-section threaded rods is adjusted accordingly according to the diameter of the bar. After the splicing adjustment is completed, the PLC device controls the rotation of the rotating shaft of the double-axis motor 11 so that the mounting seat 10 moves to the corresponding position. At this time, the side wall of the flipping belt 212 contacts the bar, and the operation of the double-axis motor 11 is stopped, so that the saw blade cuts the bar. After cutting for a certain period of time, due to the large diameter of the bar, the bar needs to be flipped. At this time, the double-axis motor 11 is continued to be controlled to operate. Due to the lack of thread force, the mounting seat 10 is difficult to continue to move. At the same time, under the action of the double-axis motor 11, the first rod 23 and several first rollers 20 rotate synchronously, so that the flipping belt 212 drives the bar to rotate. After rotation, the double-axis motor 11 is stopped, and the saw blade is continued to be controlled to cut.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
