A stainless steel blank trimming device for cold rolling of stainless steel strips

Abstract

The present invention relates to the technical field of trimming devices, and particularly relates to a trimming device for stainless steel billets used in cold rolling of stainless steel strips, including a workbench and a cutting knife. Feeding mechanisms and receiving mechanisms are respectively arranged at both ends of the workbench, and a mounting frame is arranged on the workbench. The mounting frame is located between the feeding mechanism and the receiving mechanism. The beneficial effect of the present invention is that by arranging a slidable outer tube directly below the insertion hole, when the cutting knife moves to the bottommost end and finishes trimming the blank, the outer tube enters the insertion hole and is pressed down. At this time, the sliding seat is pulled and slides outwards to dial out the cut waste. When the iron rod moves directly below the magnet, the iron rod is attracted and slides upwards, and the sliding seat is reset under the abutment of the first spring. Then, as the first extension plate slides upwards, the inner rod and the outer tube are reset. This setting enables the device to automatically dial out the cut waste.

Description

Technical Field

[0001] The present invention relates to the technical field of trimming devices, and particularly relates to a trimming device for stainless steel billets used in cold rolling of stainless steel strips. Background Art

[0002] Trimming of stainless steel billets refers to removing or trimming the edges of stainless steel billets through machining or manual operation to form specified shapes, dimensions, and surface qualities. The main purpose of trimming is to remove uneven edges. After casting or forging of the billets, there may be burrs, protrusions, or depressions on the edges, and trimming can remove these unevenness and make the edges of the billets flat and smooth.

[0003] Traditional trimming devices for billets used in cold rolling of stainless steel strips have some deficiencies. For example, the degree of automation is not high, and manual operation is often relied on to move the steel strip billets, which is not only inefficient but also likely to result in insufficient cutting accuracy due to human factors, affecting product quality. In addition, the traditional equipment also has a rather rough treatment of the waste generated during the trimming process. Usually, the waste is simply allowed to fall naturally or accumulate near the machine, which not only occupies valuable production space but may also have an adverse impact on the working environment and even pose potential safety hazards.

[0004] Therefore, a trimming device for stainless steel billets used in cold rolling of stainless steel strips is needed to solve the above problems. Summary of the Invention

[0005] In order to solve the above problems, that is, to solve the problem that the existing trimming device cannot automatically move the steel strip and cannot push aside the cut waste, the present invention provides a trimming device for stainless steel billets used in cold rolling of stainless steel strips.

[0006] A trimming device for stainless steel billets used in cold rolling of stainless steel strips includes a workbench and a cutting knife. Feeding mechanisms and a receiving mechanism are respectively arranged at both ends of the workbench. An installation frame is arranged on the workbench and is located between the feeding mechanism and the receiving mechanism. A material passing hole is opened at the bottom of the installation frame. A billet is wound on the feeding mechanism, and one end of the billet passes through the material passing hole and is wound on the receiving mechanism. An installation sliding plate is slidably installed on the installation frame through a cylinder. A sliding seat is slidably installed at the bottom of the installation sliding plate. The cutting knife is installed on the sliding seat through an adjusting mechanism. A pulling mechanism and a driving mechanism are arranged on the installation frame. Both the pulling mechanism and the driving mechanism are drivingly connected to the installation sliding plate. The pulling mechanism is drivingly connected to the sliding seat, and the driving mechanism is drivingly connected to the receiving mechanism.

[0007] Preferably, the feeding mechanism includes two first side frames which are respectively and fixedly installed on both sides of one end of the upper surface of the workbench. A first winding roller is rotatably installed at the top ends of the two first side frames, and the blank is wound around the first winding roller. Two first limiting rings are fixedly installed on the outer surface of the first winding roller, and the two first limiting rings respectively abut against the inner sides of the two first side frames; through the limitation of the two first limiting rings, the first winding roller can be prevented from moving axially when rotating.

[0008] Preferably, the material receiving mechanism includes two second side frames which are respectively and fixedly installed on both sides of one end of the upper surface of the workbench far away from the first side frames. A second winding roller is rotatably installed at the top ends of the two second side frames, and one end of the blank passes through the material passing hole and is wound around the second winding roller. Two second limiting rings are fixedly installed on the outer surface of the second winding roller, and the two second limiting rings respectively abut against the inner sides of the two second side frames; through the limitation of the two second limiting rings, the second winding roller can be prevented from moving axially when rotating.

[0009] Preferably, the mounting frame is in a gate shape. The material passing holes are respectively and vertically formed through the bottom ends of the two vertical sections of the mounting frame. The air cylinder is fixedly installed at the top end of the mounting frame, and the telescopic end of the air cylinder passes through the top wall of the mounting frame and is fixedly connected to the upper surface of the mounting slide plate. The two ends of the mounting slide plate respectively abut against the inner sides of the two vertical sections of the mounting frame.

[0010] Preferably, two symmetrically arranged mounting chutes are respectively formed at both ends of the mounting slide plate. Two hook plates are symmetrically and fixedly installed at both ends of the upper surface of the sliding seat. The two hook plates on the same sliding seat respectively slide in the two symmetrically arranged mounting chutes at both ends of the mounting slide plate. Two sliding seats are slidably installed at the bottom of the mounting slide plate. A first spring is arranged between the hook plate and the outer end of the mounting chute; when the first spring is not squeezed, the hook plate abuts against the inner end of the mounting chute.

[0011] Preferably, the adjusting mechanism includes a tool holder. An adjusting screw rod is installed through the tool holder near the middle position. The inner end of the adjusting screw rod extends into the sliding seat and is coaxially and fixedly installed with a third limiting ring. The outer diameter of the third limiting ring is larger than the diameter of the adjusting screw rod. The outer end of the adjusting screw rod is coaxially and fixedly installed with a handle. Smooth rods are fixedly installed on both sides of the outer side of the sliding seat. The smooth rods penetrate through the tool holder. The cutting tool is fixedly installed at the bottom of the tool holder. An extension tool is fixedly installed at one end of the cutting tool close to the first winding roller. The extension tool is perpendicular to the cutting tool. By slidingly installing the tool holder carrying the cutting tool on the outer side of the sliding seat through the smooth rods and making one end of the adjusting screw rod threadedly connected to the tool holder rotate on the sliding seat, the position of the tool holder can be adjusted by rotating the adjusting screw rod, so as to adjust the distance between the two cutting tools, making the device applicable to blanks of various widths. By providing an extension tool perpendicular to the cutting tool and making the extension tool located at one end of the cutting tool close to the first winding roller, the waste material can be completely cut off from the blank, facilitating the subsequent removal of the waste material.

[0012] Preferably, inner cavities are provided in both vertical sections of the mounting frame. The middle position of the inner side of the inner cavity is communicated with the outside through a vertical sliding hole. First extension plates are fixedly installed at the middle positions of both ends of the mounting slide plate. The first extension plates pass through the vertical sliding holes and extend into the inner cavities.

[0013] Preferably, the pulling mechanism includes a second extension plate which extends into the inner cavity through the vertical sliding hole. An insertion hole is formed at the bottom of the second extension plate. The outer side of the insertion hole is a through end. Inner recessed grooves are formed at both sides and the position near the outer side of the top of the insertion hole. Iron rods are slidably installed inside the inner recessed grooves. Transverse sliding holes are formed through both sides at the bottom end of the vertical sliding hole. Symmetric bottom sliding grooves are formed at the positions near both sides at the bottom of the inner cavity. Inner rods are slidably installed at the inner ends of the bottom sliding grooves through second springs. Limiting sliding grooves are symmetrically formed at both sides of the bottom sliding grooves. Limiting sliding rods are fixedly installed through the inner rods, and both ends of the limiting sliding rods slide in the two limiting sliding grooves respectively. Rope passing holes are formed through the outer ends of the bottom sliding grooves. Shafts for winding are fixedly installed at both sides near the top end in the inner cavity. Spring ropes are fixedly installed on the outer sides of the inner rods. The other ends of the spring ropes pass through the rope passing holes, bypass the shafts for winding, and are fixedly connected with the first extension plate. The pulling force of the second spring is greater than that of the spring rope. Outer tubes are slidably installed on the outer parts of the inner rods. The top end inside the outer tube and the top end of the inner rod are connected through a third spring. Blocking blocks are fixedly installed at both sides near the bottom end in the inner cavity. Magnets are fixedly installed at the positions near the outer sides of the bottoms of the blocking blocks. When the first extension plate is at the topmost position, the outer tube pops up, and the inner end of the blocking block abuts against the outer side of the outer tube. At this time, the second extension plate slides in the vertical sliding hole, and the insertion hole is directly above the outer tube. By arranging a slidable outer tube directly below the insertion hole and connecting the inner rod with the first extension plate through a spring rope, when the first extension plate slides down, the inner rod is pulled through the spring rope. Due to the blocking of the outer tube by the blocking block, the inner rod cannot slide. After the cutting knife moves to the bottommost position to finish trimming the blank, the outer tube enters the insertion hole and is pressed down until the upper surface of the second extension plate is flush with the upper surface of the transverse sliding hole. At this time, the sliding seat is pulled to slide outwards to push out the trimmed waste. When the iron rod moves directly below the magnet, the iron rod is attracted and slides upwards, and the sliding seat resets under the abutment of the first spring. Then, as the first extension plate slides upwards, the inner rod and the outer tube reset. This setting enables the device to automatically push aside the trimmed waste.

[0014] Preferably, the driving mechanism includes a top shaft and a bottom shaft, which are rotatably mounted on the top and bottom ends of the inner cavity near the outside respectively, and the top shaft and the bottom shaft are connected via a second transmission belt, the first extension plate is fixedly connected to one side of the second transmission belt, an active bevel gear ring is coaxially fixedly mounted on the top shaft, a linkage shaft is rotatably mounted in one of the side walls of the mounting frame, a driven bevel gear ring is coaxially fixedly mounted on one end of the linkage shaft, the driven bevel gear ring is meshingly connected with the active bevel gear ring, a fourth limiting ring is coaxially fixedly mounted on the outer surface of the linkage shaft, the fourth limiting ring rotates in the mounting frame, and the other end of the linkage shaft extends to the outside of the mounting frame and is connected to the second winding roller via the first transmission belt.

[0015] Preferably, the inner surface of the driven bevel gear ring is provided with a helical tooth groove, the outer surface of the linkage shaft is provided with an inner contraction cavity, the interior of the inner contraction cavity is slidably installed with a helical tooth block through a fourth spring, and the helical tooth block is pressed against the helical tooth groove; by rotatably installing the second transmission belt in the inner cavity, and making the first extension plate fixedly connected to one side of the second transmission belt, when the first extension plate slides up and down, it will drive the second transmission belt to rotate, and then the second winding roller is driven and connected to the top shaft through the two bevel gear rings, the linkage shaft and the first transmission belt, so that the first extension plate which slides up and down can drive the second winding roller to rotate. In addition, through the action of the helical tooth groove and the helical tooth block, the first extension plate can drive the second winding roller to rotate only when it slides upward. Through this arrangement, the present equipment can automatically drive the blank, without the need to manually move the blank, effectively improving the working efficiency. In addition, by controlling the extension length of the cylinder, the forward length of the blank can be controlled to achieve seamless cutting.

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention arranges a slidable outer tube just below the insertion hole, and connects the inner rod to the first extension plate through a spring rope. When the first extension plate slides down, the inner rod is pulled by the spring rope. Due to the blocking of the outer tube by the blocking block, the inner rod cannot slide. When the cutting knife moves to the bottom to complete the edge trimming of the blank, the outer tube enters the insertion hole and is pressed down until the upper surface of the second extension plate is flush with the upper surface of the transverse sliding hole. At this time, the slide seat is pulled to slide outward to push out the cut waste. When the iron rod moves to just below the magnet, the iron rod is attracted to slide up, and the slide seat is reset under the support of the first spring. Then, as the first extension plate slides up, the inner rod and the outer tube are reset. This arrangement enables the device to automatically push out the cut waste.

[0018] 2. In the present invention, a tool holder carrying a cutting tool is slidably mounted on the outer side of the sliding seat through a smooth rod, and one end of an adjusting screw rod threadedly connected to the tool holder rotates on the sliding seat. By rotating the adjusting screw rod, the position of the tool holder can be adjusted, thereby adjusting the distance between the two cutting tools, so that the device is applicable to blanks of various widths. By providing an extended tool perpendicular to the cutting tool and making the extended tool located at one end of the cutting tool close to the first winding roller, the waste material can be completely cut off from the blank, facilitating the subsequent removal of the waste material.

[0019] 3. In the present invention, a second transmission belt is rotatably mounted in the inner cavity, and the first extension plate is fixedly connected to one side of the second transmission belt. When the first extension plate slides up and down, it will drive the second transmission belt to rotate. Then, through two bevel gear rings, a linkage shaft and a first transmission belt, the second winding roller is drivingly connected to the top shaft, so that the second winding roller can be driven to rotate by the first extension plate sliding up and down. In addition, through the action of the helical tooth groove and the helical tooth block, the first extension plate can only drive the second winding roller to rotate when sliding upward. Through this setting, the device can automatically drive the blank without manual movement of the blank, effectively improving the working efficiency. In addition, by controlling the extension length of the cylinder, the forward length of the blank can be controlled to achieve seamless cutting. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0032] The following describes the preferred implementation modes of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these implementation modes are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0033] As Figure 1-2 shown, an edge trimming device for stainless steel blanks used in cold rolling of stainless steel strips according to an embodiment of the present invention includes a workbench 1 and a cutting knife 2. A feeding mechanism and a material collecting mechanism are respectively arranged at both ends of the workbench 1. A mounting frame 3 is arranged on the workbench 1. The mounting frame 3 is located between the feeding mechanism and the material collecting mechanism. A material passing hole 4 is opened at the bottom of the mounting frame 3. A blank 5 is wound on the feeding mechanism. One end of the blank 5 passes through the material passing hole 4 and is wound onto the material collecting mechanism. An installation slide plate 7 is slidably mounted on the mounting frame 3 through a cylinder 6. A slide seat 8 is slidably mounted at the bottom of the installation slide plate 7. The cutting knife 2 is mounted on the slide seat 8 through an adjusting mechanism. A pulling mechanism and a driving mechanism are arranged on the mounting frame 3. Both the pulling mechanism and the driving mechanism are drivingly connected to the installation slide plate 7. The pulling mechanism is drivingly connected to the slide seat 8. The driving mechanism is drivingly connected to the material collecting mechanism.

[0034] As Figure 1As shown in the figure, the feeding mechanism includes two first side frames 9, which are respectively and fixedly installed on both sides of one end of the upper surface of the workbench 1. The top ends of the two first side frames 9 are rotatably installed with a first winding roller 10. The blank 5 is wound around the first winding roller 10. Two first limiting rings 11 are fixedly installed on the outer surface of the first winding roller 10, and the two first limiting rings 11 respectively abut against the inner sides of the two first side frames 9. Through the limitation of the two first limiting rings 11, the first winding roller 10 can be prevented from moving axially when rotating.

[0035] As Figure 1 shown in the figure, the material receiving mechanism includes two second side frames 12, which are respectively and fixedly installed on both sides of the other end of the upper surface of the workbench 1 away from the first side frames 9. The top ends of the two second side frames 12 are rotatably installed with a second winding roller 13. One end of the blank 5 passes through the material passing hole 4 and is wound around the second winding roller 13. Two second limiting rings 14 are fixedly installed on the outer surface of the second winding roller 13, and the two second limiting rings 14 respectively abut against the inner sides of the two second side frames 12. Through the limitation of the two second limiting rings 14, the second winding roller 13 can be prevented from moving axially when rotating.

[0036] As Figure 1 shown in the figure, the mounting frame 3 is in a gate shape. Through holes 4 are respectively formed at the bottom ends of the two vertical sections of the mounting frame 3. The air cylinder 6 is fixedly installed at the top end of the mounting frame 3. The telescopic end of the air cylinder 6 passes through the top wall of the mounting frame 3 and is fixedly connected to the upper surface of the mounting slide plate 7. The two ends of the mounting slide plate 7 respectively abut against the inner sides of the two vertical sections of the mounting frame 3.

[0037] As Figure 2-4 shown in the figure, two symmetrically arranged mounting chutes 15 are respectively formed at both ends of the mounting slide plate 7. Hook plates 16 are symmetrically and fixedly installed at both ends of the upper surface of the sliding seat 8. The two hook plates 16 on the same sliding seat 8 respectively slide in the two symmetrically arranged mounting chutes 15 at both ends of the mounting slide plate 7. Two sliding seats 8 are slidably installed at the bottom of the mounting slide plate 7. A first spring 17 is arranged between the hook plate 16 and the outer end of the mounting chute 15. When the first spring 17 is not compressed, the hook plate 16 abuts against the inner end of the mounting chute 15.

[0038] As Figure 4-5As shown in the figure, the adjusting mechanism includes a tool holder 18. An adjusting screw rod 19 is installed through the tool holder 18 near the middle position in a threaded manner. The inner end of the adjusting screw rod 19 extends into the sliding seat 8 and is coaxially and fixedly installed with a third limiting ring 20. The outer diameter of the third limiting ring 20 is larger than the diameter of the adjusting screw rod 19. The outer end of the adjusting screw rod 19 is coaxially and fixedly installed with a grip 21. Smooth rods 22 are fixedly installed on both sides of the outer side of the sliding seat 8. The smooth rods 22 penetrate through the tool holder 18. The cutting tool 2 is fixedly installed at the bottom of the tool holder 18. An extension tool 23 is fixedly installed at one end of the cutting tool 2 close to the first winding roller 10. The extension tool 23 is perpendicular to the cutting tool 2. By slidingly installing the tool holder 18 carrying the cutting tool 2 on the outer side of the sliding seat 8 through the smooth rods 22, and rotating one end of the adjusting screw rod 19 threadedly connected to the tool holder 18 on the sliding seat 8, by rotating the adjusting screw rod 19, the position of the tool holder 18 can be adjusted, so as to adjust the distance between the two cutting tools 2, so that this device is applicable to blanks 5 of various widths. By providing the extension tool 23 perpendicular to the cutting tool 2 and making the extension tool 23 located at one end of the cutting tool 2 close to the first winding roller 10, the waste material can be completely cut off from the blank 5, which is convenient for subsequently removing the waste material.

[0039] As Figure 1-2 shown, inner cavities 24 are respectively opened in the two vertical sections of the mounting frame 3. The middle position of the inner side of the inner cavity 24 is communicated with the outside through vertical sliding holes 25. First extension plates 26 are fixedly installed at the middle positions of both ends of the mounting slide plate 7. The first extension plates 26 pass through the vertical sliding holes 25 and extend into the inner cavities 24.

[0040] As Figure 1 、 Figure 4 and Figure 6-8As shown, the pulling mechanism includes a second extension plate 27. The second extension plate 27 passes through the vertical sliding hole 25 and extends into the inner cavity 24. An insertion hole 28 is formed at the bottom of the second extension plate 27. The outer side of the insertion hole 28 is a through end. Inner recessed grooves 29 are formed at the positions near the outer side on both sides and the top of the insertion hole 28. Iron rods 30 are slidably installed inside the inner recessed grooves 29. Transverse sliding holes 31 are formed through both sides at the bottom end of the vertical sliding hole 25. Bottom sliding grooves 32 are symmetrically formed at the positions near both sides at the bottom of the inner cavity 24. Inner rods 34 are slidably installed at the inner ends of the bottom sliding grooves 32 through second springs 33. Limiting sliding grooves 35 are symmetrically formed on both sides of the bottom sliding grooves 32. Limiting sliding rods 36 are fixedly installed through the inner rods 34. Both ends of the limiting sliding rods 36 are respectively slid in the two limiting sliding grooves 35. Rope passing holes 37 are formed through the outer ends of the bottom sliding grooves 32. Winding shafts 38 are fixedly installed on both sides near the top in the inner cavity 24. Spring ropes 39 are fixedly installed on the outer sides of the inner rods 34. The other ends of the spring ropes 39 pass through the rope passing holes 37, bypass the winding shafts 38, and are fixedly connected to the first extension plate 26. The pulling force of the second spring 33 is greater than the pulling force of the spring rope 39. An outer tube 40 is slidably installed outside the inner rod 34. The top end inside the outer tube 40 and the top end of the inner rod 34 are connected through a third spring 41. Blocking blocks 42 are fixedly installed on both sides near the bottom end of the inner cavity 24. Magnets 43 are fixedly installed at the positions near the outer side at the bottom of the blocking blocks 42. When the first extension plate 26 is at the topmost position, the outer tube 40 pops up. The inner end of the blocking block 42 abuts against the outer side of the outer tube 40. At this time, the second extension plate 27 slides in the vertical sliding hole 25, and the insertion hole 28 is directly above the outer tube 40. By arranging a slidable outer tube 40 directly below the insertion hole 28 and connecting the inner rod 34 to the first extension plate 26 through the spring rope 39, when the first extension plate 26 slides down, the inner rod 34 is pulled through the spring rope 39. Due to the blocking of the outer tube 40 by the blocking block 42, the inner rod 34 cannot slide. When the cutting knife 2 moves to the bottommost position and finishes trimming the blank 5, the outer tube 40 enters the insertion hole 28 and is pressed down until the upper surface of the second extension plate 27 is flush with the upper surface of the transverse sliding hole 31. At this time, the sliding seat 8 is pulled to slide outwards to push out the trimmed waste. When the iron rod 30 moves directly below the magnet 43, the iron rod 30 is attracted and slides upwards. The sliding seat 8 is reset under the abutment of the first spring 17. Then, as the first extension plate 26 slides upwards, the inner rod 34 and the outer tube 40 are reset. This setting enables the device to automatically push aside the trimmed waste.

[0041] As Figure 1 and Figure 9As shown, the driving mechanism includes a top shaft 44 and a bottom shaft 45, which are rotatably mounted at the top and bottom ends of the inner cavity 24, respectively, near the outer side. The top shaft 44 and the bottom shaft 45 are connected by a second transmission belt 46. The first extension plate 26 is fixedly connected to one side of the second transmission belt 46. An active bevel gear ring 47 is coaxially fixedly mounted on the top shaft 44. A linkage shaft 48 is rotatably mounted in one of the side walls of the mounting frame 3. A driven bevel gear ring 49 is coaxially fixedly mounted on one end of the linkage shaft 48. The driven bevel gear ring 49 is meshed with the active bevel gear ring 47. A fourth limiting ring 50 is coaxially fixedly mounted on the outer surface of the linkage shaft 48. The fourth limiting ring 50 rotates in the mounting frame 3. The other end of the linkage shaft 48 extends to the outside of the mounting frame 3 and is connected to the second winding roller 13 by a first transmission belt 51.

[0042] like Figure 10 As shown, the inner surface of the driven bevel gear ring 49 is provided with a helical tooth groove 52, and the outer surface of the linkage shaft 48 is provided with a retracted cavity 53. A helical tooth block 55 is slidably installed inside the retracted cavity 53 through a fourth spring 54, and the helical tooth block 55 abuts against the helical tooth groove 52; by rotating the second transmission belt 46 in the inner cavity 24, and making the first extension plate 26 fixedly connected to one side of the second transmission belt 46, when the first extension plate 26 slides up and down, it will drive the second transmission belt 46 to rotate, and then through the two bevel gear rings, the linkage shaft 48 and the first transmission belt 51 The second winding roller 13 is driven and connected to the top shaft 44, so that the first extension plate 26 that slides up and down can drive the second winding roller 13 to rotate. In addition, through the action of the bevel tooth groove 52 and the bevel tooth block 55, the first extension plate 26 can drive the second winding roller 13 to rotate only when it slides upward. Through this arrangement, the equipment can automatically drive the blank 5 without manual movement of the blank 5, which effectively improves the work efficiency. In addition, by controlling the extension length of the cylinder 6, the forward length of the blank 5 can be controlled to achieve seamless cutting.
