Description

Technical Field

[0001] The present invention belongs to the technical field of cutting equipment, and particularly relates to a stainless steel wire cutting device. Background Art

[0002] Stainless steel wire, also known as stainless steel line, is a wire product of various specifications made of stainless steel as raw material. All categories of stainless steel wire are mainly characterized by high corrosion resistance. Depending on the usage scenario, it may also have characteristics such as high tensile strength, brightness, and fatigue resistance. Stainless steel is an alloy steel, mainly composed of iron, and also contains high-quality metal elements such as chromium, nickel, and molybdenum. The main component can also contain titanium element, which can form stable titanium carbide with carbon in the steel, thereby fixing the carbon element in the steel and preventing the precipitation of chromium carbide at the grain boundary, and effectively improving the intergranular corrosion resistance of stainless steel. It has a wide range of applications in fields such as aerospace and petrochemical industry.

[0003] After the production of stainless steel wire, it is shipped out in a coiled specification. During actual use, it needs to be cut according to requirements. When encountering a large number of cuts, a suitable cutting device can greatly reduce the labor intensity, and the cutting by the device can ensure the uniformity of the cutting length.

[0004] Chinese invention patent with publication number CN117772957A discloses a steel wire cutting device for electronic wire harness production, including a base plate. Two fixing plates are symmetrically arranged on the base plate. Two rotating shafts are arranged between the two fixing plates.

A square hole is provided on one of the fixing plates, and a steel pipe is rotatably arranged at the square hole. A driving gear is connected to the circumferential outer wall of the steel pipe. Although this invention patent can complete the cutting, it cannot limit the position of the stainless steel wire during the cutting process and does not ensure the cutting length. In view of the above problems, the present invention provides a stainless steel wire cutting device. Summary of the Invention

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment: As Figure 1 — Figure 12 shown, a stainless steel wire cutting device includes: Base 1; A feeding mechanism movably arranged on the base 1, the feeding mechanism includes at least one hopper 2, and the hopper 2 is used to convey a winding roller 41 wound with stainless steel wire 42; As Figure 1 , Figure 2 shown, when feeding, multiple hoppers 2 can be connected in series, and moving wheels matching the tracks on the base 1 are arranged below the hoppers 2. To facilitate the movement of the hopper 2 on the base 1, it can be in the form of manual pushing. Of course, a power device can also be arranged on the hopper 2 to drive the moving wheels to move on the base 1 through the power device. This belongs to the prior art and can be adopted by those skilled in the art. When cutting the stainless steel wire 42 wound on the winding roller 41, the winding roller 41 is placed in the hopper 2, and the stainless steel wire 42 is moved to the cutting mechanism through the hopper 2.

[0030] A pressing mechanism arranged on the base 1, the pressing mechanism includes a rotating plate 14, and when cutting the stainless steel wire 42, the rotating plate 14 is used to press the winding roller 41; A cutting mechanism, the cutting mechanism is connected to the rotating plate 14, the cutting mechanism includes a plurality of cutting knives 40 arranged in a circular pattern, and the cutting knife 40 extrusion plate 4 is used to cut the stainless steel wire 42.

[0031] The feeding mechanism further includes an extrusion plate 4, the extrusion plate 4 is located above the inner bottom surface of the hopper 2, a first return spring 5 is arranged between the extrusion plate 4 and the hopper 2, the extrusion plate 4 is fixedly connected to an extrusion block 6, the extrusion block 6 is slidably matched with the hopper 2, the end of the extrusion block 6 away from the extrusion plate 4 is arc-shaped, and two groups of ball bearings 3 arranged in a circular pattern are arranged inside the hopper 2, and each group of ball bearings 3 consists of a plurality of ball bearings 3.

[0032] The feeding mechanism further includes two symmetrically arranged moving frames 7, the moving frames 7 are located on both sides of the extrusion plate 4, the moving frames 7 are slidably matched with the hopper 2, and the end of the moving frame 7 located outside the hopper 2 is arc-shaped.

[0033] As Figure 1 —— Figure 4 shown, two groups of symmetrically arranged ball bearings 3 are arranged inside the hopper 2, each group of ball bearings 3 has a plurality of ball bearings 3, the ball bearings 3 are rotationally matched with the inside of the hopper 2, when the winding roller 41 is placed inside the hopper 2, both ends of the winding roller 41 respectively land on the two groups of ball bearings 3, and when the friction wheel 26 drives the winding roller 41 to rotate through friction, the function of the ball bearings 3 is to reduce the friction of the winding roller 41 and assist the winding roller 41 to rotate.

[0034] During the process of placing the winding roller 41 inside the carriage 2, the winding roller 41 and the stainless steel wire 42 will come into contact with the pressing plate 4 and press the pressing plate 4 downward by gravity. At this time, the pressing plate 4 drives the pressing block 6 fixedly installed below to move downward. During this process, the first reset spring 5 will be compressed. The function of the first reset spring 5 is to assist the reset of the pressing plate 4. Of course, the winding roller 41 will also press the moving frame 7 downward. A reset spring identical to the first reset spring 5 is provided between the moving frame 7 and the carriage 2, facilitating the reset of the moving frame 7.

[0035] The pressing mechanism further includes two symmetrically arranged L-shaped rods 10. The L-shaped rods 10 are slidably engaged with the base 1, and a third reset spring 12 is provided between the L-shaped rods 10 and the base 1. One end of the L-shaped rod 10 is provided with a first inclined surface 11, and the other end of the L-shaped rod 10 is provided with a second inclined surface 13. A surface matching the second inclined surface 13 is provided on the rotating plate 14. The first inclined surface 11 is slidably engaged with the driving block 8. The driving block 8 is slidably engaged with the base 1, and a second reset spring 9 is provided between the driving block 8 and the base 1. The upper end of the driving block 8 is arc-shaped.

[0036] As Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 shown, when the carriage 2 with the winding roller 41 moves on the base 1 towards the side close to the wire groove 32, first, a moving frame 7 on the carriage 2 will come into contact with the driving block 8 slidably installed on the base 1. And as the moving frame 7 moves, the driving block 8 will move downward, thereby driving the L-shaped rod 10 to slide on the base 1 through the driving block 8 and the second reset spring 9. However, since at this time another moving frame 7 on the carriage 2 is not in contact with another driving block 8, the moving L-shaped rod 10 cannot cause the rotating plate 14 to rotate at this time; as the carriage 2 moves, the two moving frames 7 on the carriage 2 will simultaneously come into contact with the two driving blocks 8 (as Figure 5 shown, for simultaneous contact). In this way, the two driving blocks 8 slide downward along the base 1 at the same time. Through the first inclined surface 11, the two L-shaped rods 10 move away from each other. In this way, the second inclined surface 13 on the L-shaped rod 10 will move away from the rotating plate 14, so that the side of the rotating plate 14 close to the second inclined surface 13 is lowered. The purpose of this is to enable the lowered rotating plate 14 to come into contact with the stainless steel wire 42 and play a stabilizing role for the stainless steel wire 42, preventing the winding roller 41 and the stainless steel wire 42 from shifting when the friction wheel 26 drives the winding roller 41 to rotate. The compressed third reset spring 12 and the second reset spring 9 both serve to assist in reset. It should be noted that the side of the rotating plate 14 connected to the second belt pulley assembly 25 can be rotatably engaged with a support structure such as a bracket on the [structure not specified in the original text]. Therefore, when the second inclined surface 13 moves relative to the rotating plate 14, the rotating plate 14 can rotate without falling off.

[0037] The pressing mechanism further includes a connecting plate 15 connected to the base 1 through a fourth return spring 17. The connecting plate 15 is located between two L-shaped rods 10. Bevel surfaces three 16 are provided on both sides of the connecting plate 15. One end of a driving rod 18 is rotatably installed on the connecting plate 15. The other end of the driving rod 18 is rotatably connected to a sliding plate 19. The sliding plate 19 is slidably installed on the base 1. A connecting cylinder 20 is fixedly installed on the sliding plate 19. A connecting shaft 21 is rotatably installed on the connecting cylinder 20. Active gears 22 are fixedly installed at both ends of the connecting shaft 21. One end of the connecting shaft 21 is connected to a first bevel gear set 27. The first bevel gear set 27 is connected to a power assembly. The active gears 22 are connected to a position-changing assembly.

[0038] As Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, during the movement of the carriage 2, when the two moving frames 7 respectively contact the driving blocks 8, the pressing block 6 located between the two moving frames 7 also moves above the connecting plate 15. Since bevel surfaces three 16 are provided on both sides of the connecting plate 15 and the lower part of the pressing block 6 is arc-shaped, the pressing block 6 can smoothly reach above the connecting plate 15 and simultaneously press down the connecting plate 15 and the fourth return spring 17. The function of the fourth return spring 17 is to assist the connecting plate 15 in resetting.

[0039] During the downward movement of the connecting plate 15, the connecting plate 15 drives the sliding plate 19 to move on the base 1 towards the side close to the first pulley assembly 24 through the driving rod 18, so that the connecting shaft 21 rotatably connected to the connecting cylinder 20 drives the active gears 22 to approach the driven gears 23 and finally mesh with the driven gears 23. The first bevel gear set 27 includes a driving bevel gear and a driven bevel gear. The driven bevel gear is installed on the connecting shaft 21. As the connecting shaft 21 moves, the driven bevel gear moves to mesh with the driving bevel gear installed on the third pulley assembly 28. How to arrange the bevel gears belongs to the prior art and can be achieved by those skilled in the art.

[0040] The position-changing assembly includes two symmetrically arranged driven gears 23. The driven gears 23 are connected to one end of the first pulley assembly 24. The other end of the first pulley assembly 24 is connected to one end of the second pulley assembly 25. The other end of the second pulley assembly 25 is connected to a friction wheel 26. The friction wheel 26 is rotatably installed on the rotating plate 14. The connection between the first pulley assembly 24 and the second pulley assembly 25 is rotatably connected coaxially. The first pulley assembly 24 is installed on the base 1 through a support frame.

[0041] The power assembly includes a third pulley assembly 28 disposed on the base 1. One end of the third pulley assembly 28 is connected to the first bevel gear set 27, and the other end of the third pulley assembly 28 is connected to the second bevel gear set 29. The second bevel gear set 29 is connected to the motor 30 fixedly installed on the base 1.

[0042] When cutting the stainless steel wire 42, start the motor 30. The motor 30 drives the second bevel gear set 29 to rotate. At this time, the second bevel gear set 29 drives the third pulley assembly 28 to rotate. The third pulley assembly 28 drives the connecting shaft 21 to rotate on the connecting cylinder 20 through the first bevel gear set 27, so that the driven gear 23 meshing with the driving gear 22 drives the first pulley assembly 24 to rotate on the support frame. The connection between the first pulley assembly 24 and the second pulley assembly 25 is coaxially connected. Therefore, the rotating first pulley assembly 24 drives the second pulley assembly 25 to rotate. The two second pulley assemblies 25 drive the friction wheel 26 to rotate. The friction wheel 26 drives the wire winding roller 41 to rotate on the ball 3 through friction, so that the stainless steel wire 42 wound on the wire winding roller 41 continuously moves into the wire groove 32.

[0043] During the continuous cutting of the stainless steel wire 42, the sum of the gravity of the wire winding roller 41 and the car hopper 2 will gradually decrease. Therefore, under the elastic force of the third return spring 12, the two L-shaped rods 10 will gradually approach each other, and one end of the rotating plate 14 close to the wire groove 32 will gradually rise. Of course, during this process, the extrusion block 6 will continuously press the connecting plate 15, and the connecting plate 15 will not move upward, which also ensures that the driving rod 18 will not drive the sliding plate 19, the connecting shaft 21, etc. to reset, that is, the driving gear 22 on the connecting shaft 21 will continuously maintain meshing with the driven gear 23. When the car hopper 2 leaves above the connecting plate 15, the connecting plate 15 will reset.

[0044] In addition, it is possible for those skilled in the art to drive the third pulley assembly 28 by driving the second bevel gear set 29 through the motor 30. For example, a belt can be connected to the output shaft of the motor 30, and then a transmission shaft is connected to the belt. The transmission shaft is connected to the second bevel gear set 29. The second bevel gear set 29, like the first bevel gear set 27, includes a driving bevel gear and a driven bevel gear, and the driving bevel gear and the driven bevel gear are meshed and matched.

[0045] The cutting mechanism further includes a fixed wheel 38. The rotating wheel 37 is rotationally engaged with the fixed wheel 38, and a fifth return spring 39 is provided between the rotating wheel 37 and the fixed wheel 38. The cutting knives 40 are arranged in a circle on the fixed wheel 38. One side of the cutting knife 40 is rotationally engaged with the fixed wheel 38, and the other side of the cutting knife 40 is slidably engaged with a rectangular groove provided on the rotating wheel 37. A cylinder 36 is fixedly installed on the fixed wheel 38. The extending end of the cylinder 36 is hinged to the rotating wheel 37. When the extending end of the cylinder 36 pushes the rotating wheel 37 to rotate, the rectangular groove on the rotating wheel 37 drives the cutting knife 40 to rotate on the fixed wheel 38 in a direction close to the central axis of the fixed wheel 38, thereby cutting off the stainless steel wire 42.

[0046] The cutting mechanism further includes a hollow wire groove 32. One end of the wire groove 32 is connected to a vertical rod 34 fixedly installed on the base 1, and the other end of the wire groove 32 is arranged in front of the rotating plate 14. Two symmetrically arranged wire feeding wheels 33 are provided at one end of the wire groove 32 close to the rotating plate 14. Two symmetrically arranged photoelectric sensors 35 are provided at one end of the wire groove 32 close to the vertical rod 34. The wire feeding wheels 33 are connected to the motor 30 through a fourth belt pulley assembly 31.

[0047] As Figure 1 , Figure 2 , Figure 9 —— Figure 12 As shown, when cutting the stainless steel wire 42, first insert one end of the stainless steel wire 42 into the wire groove 32 and insert one end between the two wire feeding wheels 33. When starting the motor 30, the motor 30 drives the wire feeding wheels 33 to rotate through the fourth belt pulley assembly 31, thereby continuously conveying the stainless steel wire 42 to the side close to the photoelectric sensor 35. The fourth belt pulley assembly 31 can also be connected to a transmission shaft to obtain power.

[0048] When the stainless steel wire 42 enters the wire groove 32 and moves towards the photoelectric sensor 35, the stainless steel wire 42 also passes through the central holes between the multiple cutting knives 40. When the stainless steel wire 42 moves to the photoelectric sensor 35, the photoelectric sensor 35 will obtain a signal on one side, thereby starting the cylinder 36 through the control center, causing the cylinder 36 to push the rotating wheel 37 to rotate. During the rotation of the rotating wheel 37, the rectangular groove on the rotating wheel 37 will push the cutting knife 40 to move towards the side close to the central axis and finally come into contact with each other, thereby cutting off the stainless steel wire 42 located in the center. The cut stainless steel wire 42 can be taken away by a manipulator or the like.

[0049] After a cutting is completed, the air cylinder 36 drives the rotating wheel 37 to reset. The function of the return spring five 39 is to assist the rotating wheel 37 in resetting. Then the stainless steel wire 42 will continue to move in the wire groove 32. When the photoelectric sensor 35 detects the stainless steel wire 42 again, the air cylinder 36 will be started again, thereby intermittently completing the cutting. Of course, in order to adjust the length of the stainless steel wire 42 for cutting, the position of the photoelectric sensor 35 relative to the rotating wheel 37 can also be flexibly adjusted.

[0050] After the stainless steel wire 42 on a winding roller 41 is cut, move the hopper 2 to move another hopper 2 loaded with the stainless steel wire 42 under the rotating plate 14 for cutting.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as above. For the sake of brevity, they are not provided in detail; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
