[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the utility model.

[0027] As shown in the drawings, Figures 1-7 The embodiment discloses a special-shaped stainless steel wire rod cutting equipment, which comprises a base 1 connected with an external conveying mechanism 2, and a cutting device 3 is arranged on the base 1. The cutting device 3 comprises a mounting frame 31 arranged on the base 1, the mounting frame 31 is arranged at the end of the conveying mechanism 2, and a cutter mechanism 4 and a supporting mechanism 5 are sequentially arranged on the mounting frame 31 along the wire rod conveying direction. The cutter mechanism 4 is used for cutting the wire rod in a quantitative and fixed-length manner, and the supporting mechanism 5 is used for supporting the part of the wire rod away from the cutter mechanism 4, so that when the cutter mechanism 4 cuts the wire rod, the wire rod in the suspended part cannot be deformed and bent due to the stress of the cutting part in the cutting process, the flatness of the wire rod cutting surface is ensured, and the influence on the subsequent processing process of the wire rod is avoided.

[0028] As shown in the drawings, Figure 2 In the cutting device 3, a clamping mechanism 6 is further arranged on the mounting frame 31. The clamping mechanism 6 is arranged on the side, away from the supporting mechanism 5, of the cutter mechanism 4. The clamping mechanism 6 is used for clamping the wire rod, cooperates with the supporting mechanism 5, fixes and positions the two ends of the cut wire rod part, and thus ensures the accuracy of the position of the wire rod.

[0029] As shown in the drawings, Figures 2-3As shown, the clamping mechanism 6 includes a pair of clamping pieces 61 symmetrically arranged on both sides of the mounting frame 31, a wire passage 62 is formed between the pair of clamping pieces 61 for the wire to pass through, and a pressing piece 63 is arranged above the wire passage 62, which is used to apply a downward force to the wire.

[0030] Specifically, the clamping piece 61 includes a limiting plate 611 arranged on the mounting frame 31, the wire passage 62 is formed by a pair of limiting plates 611, and a plurality of side pressing rods 612 are arranged above the limiting plate 611 in the wire conveying direction. The side pressing rods 612 are slidingly arranged above the limiting plate 611 and abut between the side pressing rods 612 and the limiting plate 611 with a spring 64. Among them, the side pressing rods 612 correspond to the middle two sides of the wire. Through the spring 64, the side pressing rods 612 can stably extrude the two sides of the wire, so as to ensure that the position of the wire in the left and right directions will not deviate. Moreover, for the special-shaped stainless steel wire, the independently arranged side pressing rods 612 can adjust the position according to the shape of the wire, so as to better adapt to wires of different shapes and ensure stable contact and action on the wire.

[0031] Meanwhile, a pressing piece 63 is also arranged above the wire passage 62, which includes a mounting plate 631 arranged on the mounting frame 31, a pressing rod 632 slidingly arranged on the mounting plate 631, and a pair of abutting heads 633 inclined from the outside to the inside of the wire passage 62 arranged at the end of the pressing rod 632. A spring 64 is arranged between the pressing rod 632 and the mounting plate 631, which is used to drive the pair of abutting heads 633 to abut with the wire. Among them, Figure 4 As shown, the abutting heads 633 are symmetrically arranged in a pair of structures with a downward middle inclination angle. Compared with the existing method of applying force to the surface of the wire through a point, the force of two points can better ensure the stability of the wire and provide more stable and uniform pressure, thereby preventing the wire from swinging or deviating during cutting. The inclination angle helps to properly guide the wire when it passes through the passage. When the wire passes through the passage, the inclined design can also exert a slight guiding force on the wire, so that the wire always stays in the middle position during cutting, so that the wire always stays in the correct position, avoiding the problem of wire displacement caused by poor clamping.

[0032] When the wire passes through the clamping mechanism 6, it will pass through the cutter mechanism 4 to the supporting mechanism 5. At this time, the supporting mechanism 5 will support the end of the wire, and the cutter mechanism 4 will work to cut the wire. Specifically, Figure 3 , 5As shown, the cutter mechanism 4 includes a lower cutter 42 arranged on the mounting frame 31 and an upper cutter 41 slidingly arranged on the mounting frame 31, the upper cutter 41 is connected with a lifting cylinder 43 electrically connected with the main control module, when the wire reaches the supporting mechanism 5 and is sensed and limited by the supporting mechanism 5, the lifting cylinder 43 is driven to drive the upper cutter 41 to slide downward to cooperate with the lower cutter 42 to realize the cutting work of the wire.

[0033] As shown in the drawings, Figures 5-7 As shown, the supporting mechanism 5 includes a supporting frame 51 arranged on the mounting frame 31, the supporting frame 51 is provided with a through hole 52 for the wire to pass through and a positioning assembly 53 corresponding to the through hole 52, the positioning assembly 53 is used for supporting and positioning the wire passing through the through hole 52. Among them, the supporting frame 51 is arranged on the mounting frame 31 through the slide rod 7, and the supporting frame 51 can slide horizontally along the wire conveying direction relative to the cutter mechanism 4 through the slide rod 7. Through the slide rod 7, the relative distance between the supporting frame 51 and the cutter mechanism 4 can be adjusted, so that the position of the supporting frame 51 can be adjusted according to the different cutting length of the wire; and the slide rod 7 can be fixed with the supporting frame 51 through bolts and the like.

[0034] As shown in the drawings, Figures 6-7 As shown, the supporting mechanism 5 includes a supporting frame 51 arranged on the mounting frame 31, the supporting frame 51 is provided with a through hole 52 for the wire to pass through and a positioning assembly 53 corresponding to the through hole 52, the positioning assembly 53 is used for supporting and positioning the wire passing through the through hole 52. Among them, the supporting frame 51 is arranged on the mounting frame 31 through the slide rod 7, and the supporting frame 51 can slide horizontally along the wire conveying direction relative to the cutter mechanism 4 through the slide rod 7. Through the slide rod 7, the relative distance between the supporting frame 51 and the cutter mechanism 4 can be adjusted, so that the position of the supporting frame 51 can be adjusted according to the different cutting length of the wire; and the slide rod 7 can be fixed with the supporting frame 51 through bolts and the like.

[0035] Specifically, a pair of support rods 531 inclined to the center of the through hole 52 are symmetrically arranged on the inner wall of the through hole 52, the pair of support rods 531 are arranged at an angle below the wire; a guide rod 532 in contact with the wire is elastically swingingly arranged at the end of the support rod 531, one end of the guide rod 532 away from the cutter mechanism 4 is a driving end 533, and the other end close to the cutter mechanism 4 is a clamping end 534; when the wire passes through the through hole 52, the wire acts on the driving end 533 to drive the guide rod 532 to swing, so that the clamping end 534 is in contact with the wire; the limiting piece 54 is arranged on the side of the supporting frame 51 away from the cutter mechanism 4 and above the through hole 52, and is used for limiting the upward bending of one end of the wire away from the cutter mechanism 4.

[0036] When the wire passes through the through hole 52, the end of the wire drives the driving end 533 of the support rod 531, thereby driving the guide rod 532 to swing upward to a horizontal state, at the same time, the clamping end 534 of the guide rod 532 swings upward, thereby achieving abutting support below the bottom of the wire, so that the wire can be stably supported on a pair of guide rods 532, avoiding the phenomenon that the end of the wire is in a suspended state and is bent and deformed downward, thereby improving the flatness of the wire cutting surface.

[0037] And the limiting piece 54 includes a limiting rod 541 arranged on the support frame 51, and the end of the limiting rod 541 away from the through hole 52 is connected with a telescopic air cylinder 543; and an infrared sensor 542 arranged above the through hole 52, the infrared sensor 542 is electrically connected with the telescopic air cylinder 543 through a main control module, when the wire passes through the infrared sensor 542, the telescopic air cylinder 543 drives the limiting rod 541 to abut against the top of the wire. The telescopic air cylinder 543 drives the limiting rod 541 to move downward, achieving abutting above the end of the wire, on the one hand, it can avoid the guide rod 532 to reset and swing under the action of the elastic piece 55 during cutting, on the other hand, it can limit the end of the wire, thereby avoiding the phenomenon that one end of the wire is raised upward due to stress under the action of the cutter during cutting of the wire by the cutter; thereby preventing the wire from bending or deforming due to uneven stress during cutting, ensuring the shape stability of the wire and avoiding uneven cutting surface or other quality problems.

[0038] And when the cutting is completed, the telescopic air cylinder 543 can control the limiting rod 541 to reset and retract, so as to release the limiting of the end of the wire, at the same time, since the wire has been cut, the cut end of the wire is also in a stress-free state, at this time, the elastic piece 55 resets to drive the limiting rod 541 to tilt, so that the cut wire can also tilt to the space between the cutter mechanism 4 and the support mechanism 5, so that the cut wire can slide out of the support mechanism 5 under the action of gravity, facilitating the subsequent entry of the wire.

[0039] At the same time, in order to ensure that the cut wire can stably fall out of the through hole 52, the user can also manually or by blowing of the air blowing device, to assist the falling of the wire, thereby improving the production efficiency.

[0040] Further, as shown in Figure 7 In order to adapt to wires with different diameters, an adjusting channel is arranged through the inner wall of the through hole 52, the support rod 531 is arranged in the adjusting channel and can reciprocate in the adjusting channel, and the end of the support rod 531 away from the guide rod 532 is rotationally connected with an adjusting rod 8, and the adjusting rod 8 is threadedly connected with the adjusting channel.

[0041] The user can rotate the adjusting rod 8, thereby driving the supporting rod 531 to slide in the adjusting channel, and then adjusting the position of the guide rod 532, so that the guide rod 532 can be adaptively adjusted according to the size of the wire.

[0042] Meanwhile, for the special-shaped stainless steel wire, a gap for the protrusion or other shape of the wire is formed between the pair of guide rods 532, so that the protruding part of the wire does not interfere with the guide rod 532 to cause instability, and the guide rod 532 is arranged on both sides, which can effectively abut and support both sides of the special-shaped wire, thereby further improving the stability of the wire support.

[0043] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
