[0021] Embodiment

[0022] The technical solution in the embodiment of the present application effectively solves the problems in the prior art of the metal hose cutting mechanism. When cutting a metal hose, due to the certain deformation ability of the metal hose, the metal hose may be deformed and bent under force during the cutting process, resulting in deviation of the cutting part, cutting mistakes, waste of raw materials, increased production costs, and the problem that manual holding of the metal hose for cutting may harm the staff during the cutting process. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a metal hose cutting mechanism, including a cutting device 11. This metal hose cutting mechanism further includes: a base 1, a rectangular plate 4, a first fixing block 5, and a second fixing block 6. The number of the first fixing blocks 5 and the second fixing blocks 6 is two each. The cutting device 11 is fixedly installed at the side end of the base 1. A slide rail 12 is opened at the upper end of the base 1. A first scale groove 15 is also opened at the upper end of the base 1. A cutting groove 13 is also opened at the upper end of the base 1. A first round hole 14 is also opened at the upper end of the base 1. An L-shaped plate 3 is fixedly installed at the upper end of the base 1. A second round hole 31 is penetrated and opened at the upper end of the L-shaped plate 3. The second round hole 31 coincides with the first round hole 14. A threaded bolt 2 is rotatably installed on the inner side wall of the second round hole 31. A sliding groove 32 is opened at the side end of the L-shaped plate 3. A second scale groove 33 is opened at the side end of the L-shaped plate 3. A positioning plate 21 is opened on the threaded bolt 2. A threaded groove 23 is penetrated and opened at the upper end of the positioning plate 21. The threaded bolt 2 is threadedly rotatably installed on the inner side wall of the threaded groove 23. A connecting plate 22 is fixedly installed on one side of the positioning plate 21. A pointer 24 is fixedly installed on the other side of the positioning plate 21. A positioning groove 43 is opened at the side end of the rectangular plate 4. The connecting plate 22 is fixedly installed on the inner side wall of the positioning groove 43. A rectangular groove 41 is opened at the lower end of the rectangular plate 4. Two first positioning holes 42 are penetrated and opened at both end parts of the inner side wall of the rectangular groove 41. The same first round rod 47 is rotatably installed between every two first positioning holes 42. Connecting rods 44 are provided on both of the two first round rods 47. Second positioning holes 45 are penetrated and opened at the side end parts of the upper sections of the two connecting rods 44. Third positioning holes 46 are penetrated and opened at the side end parts of the lower sections of the two connecting rods 44. The two connecting rods 44 are rotatably installed at the circumferential end parts of the first round rod 47 through the second positioning holes 45. When it is necessary to cut a metal hose, the user can first place the metal hose on the second fixing block 6. According to the length to be cut, the length of the hose cutting is measured and determined through the first scale groove 15, and the cutting position is marked and scribed. The marking line is aligned with the cutting groove 13. After the marking is completed, the user rotates the threaded bolt 2 to drive the positioning plate 21 to move downward. Since the pointer 24 slides in the sliding groove 32, the pointer 24 limits the positioning plate 21. The positioning plate 21 drives the rectangular plate 4 to move downward through the connecting plate 22. The rectangular plate 4 moves downward to drive the two first round rods 47 to move downward through each first positioning hole 42. The two first round rods 47 move downward to drive the two connecting rods 44 to move downward through the two second positioning holes 45. The two connecting rods 44 drive the two first fixing blocks 5 to move downward through the second round rod 52. At this time, the telescopic rod 65 contracts. The two first fixing blocks 5 and the second fixing block 6 clamp the metal hose through the first clamping groove 54 and the second clamping groove 61, so that the first rubber pad 56 and the second rubber pad 66 are closely attached to the surface of the metal hose;

[0024] The upper ends of both of the two first fixing blocks 5 are each provided with a first groove 53, the lower ends of both of the two first fixing blocks 5 are each provided with a first clamping groove 54, the lower ends of both of the two first fixing blocks 5 and on both sides of the first clamping groove 54 are each provided with a first circular groove 55, both sides of the two first fixing blocks 5 are each penetrated with a fourth positioning hole 51, and a second circular rod 52 is rotatably installed between each of the two fourth positioning holes 51 and the third positioning hole 46. The inner side walls of both of the two first clamping grooves 54 are each fixedly installed with a first rubber pad 56. Since the connecting rods 44 on both sides are inclined, when the two first fixing blocks 5 are attached to the metal hose and the two connecting rods 44 continue to move downward, the two second positioning holes 45 drive the two connecting rods 44 to rotate around the first circular rod 47. The rotation of the two connecting rods 44 causes the two third positioning holes 46 to move away from each other. The two third positioning holes 46 drive the two second circular rods 52 to move away from each other. The two second circular rods 52 drive the two first fixing blocks 5 to move to both sides through the fourth positioning holes 51. The two first fixing blocks 5 drive the two second fixing blocks 6 to move to both sides through the telescopic rods 65. At this time, the two first fixing blocks 5 and the second fixing blocks 6 stretch the metal hose to both sides and straighten the metal hose.

[0025] The upper ends of both of the two second fixing blocks 6 are each provided with a second clamping groove 61, the lower ends of both of the two second fixing blocks 6 are each provided with a second groove 62, the upper ends of both of the two second fixing blocks 6 and on both sides of the second clamping groove 61 are each provided with a second circular groove 63. The inner side walls of both of the two second clamping grooves 61 are each fixedly installed with a second rubber pad 66. A spring 64 is fixedly installed between each of the first circular grooves 55 and the second circular grooves 63. A telescopic rod 65 is fixedly installed between each of the first circular grooves 55 and the second circular grooves 63 and on the inner side wall of the spring 64. Both of the two second fixing blocks 6 are slidably installed on the slide rail 12 through the second grooves 62. Then, the user first starts the cutting device 11 to make the blade on the cutting device 11 operate, and then turns on the air cylinder. The air cylinder pushes the cutting device 11 to cut the metal hose along the cutting groove 13.

[0026] Working principle: When it is necessary to cut a metal hose, the user can first place the metal hose on the second fixed block 6. According to the length to be cut, the length of the hose cut is measured and determined through the first scale groove 15, and the cutting position is marked and scribed. The marking line is aligned with the cutting groove 13. After the marking is completed, the user rotates the threaded bolt 2, and the rotation of the threaded bolt 2 drives the positioning plate 21 to move downward. Since the pointer 24 slides in the sliding groove 32, the pointer 24 limits the positioning plate 21. The positioning plate 21 drives the rectangular plate 4 to move downward through the connecting plate 22. The downward movement of the rectangular plate 4 drives two first round rods 47 to move downward through each first positioning hole 42. The downward movement of the two first round rods 47 drives two connecting rods 44 to move downward through two second positioning holes 45. The two connecting rods 44 drive two first fixed blocks 5 to move downward through the second round rod 52. At this time, the telescopic rod 65 contracts. The two first fixed blocks 5 and the second fixed block 6 clamp the metal hose through the first clamping groove 54 and the second clamping groove 61, so that the first rubber pad 56 and the second rubber pad 66 are closely attached to the surface of the metal hose. Since the two connecting rods 44 on both sides are inclined, when the two first fixed blocks 5 are attached to the metal hose, when the two connecting rods 44 continue to move downward, the two second positioning holes 45 drive the two connecting rods 44 to rotate around the first round rod 47. The rotation of the two connecting rods 44 makes the two third positioning holes 46 move away from each other. The two third positioning holes 46 drive the two second round rods 52 to move away from each other. The two second round rods 52 drive the two first fixed blocks 5 to move to both sides through the fourth positioning hole 51. The two first fixed blocks 5 drive the two second fixed blocks 6 to move to both sides through the telescopic rod 65. At this time, the two first fixed blocks 5 and the second fixed block 6 stretch the metal hose to both sides, straighten the metal hose. Then the user first starts the cutting device 11 to make the blade on the cutting device 11 operate, and then starts the cylinder. The cylinder pushes the cutting device 11 to cut the metal hose along the cutting groove 13. When the existing metal hose cutting mechanism cuts the metal hose, because the metal hose has a certain deformation ability, the metal hose may be deformed and bent under force during the cutting process, resulting in deviation of the cutting part, causing cutting mistakes, wasting raw materials, increasing production costs, and when manually holding the metal hose for cutting, it may hurt the staff during the cutting process. This metal hose cutting mechanism is cooperated by the threaded bolt 2, the rectangular plate 4 and the connecting rod 44, which pushes the first fixed block 5 and the second fixed block 6 to clamp the metal hose, and the first fixed block 5 and the second fixed block 6 move away from each other under the push of the two connecting rods 44, so as to straighten the metal hose, avoiding inaccurate cutting caused by the metal hose being bent under force, reducing the waste of raw materials caused by cutting mistakes, and the device clamps and fixes the metal hose through the first fixed block 5 and the second fixed block 6, improving the fixing effect, without the need for manual holding of the metal hose, ensuring the safety of the staff during cutting.

[0027] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
