[0002] Wire drawing machine is an important production equipment in the metal cable industry. Generally, the wire drawing speed of the wire drawing machine is very fast. For example, the current copper wire drawing machine has a maximum drawing speed of 2400m / min. The pay-off device is an indispensable auxiliary component when the wire drawing machine is working. When the wire drawing machine is working, the pay-off device is needed to quickly and smoothly pay the metal cable into the wire drawing machine.

[0003] The traditional pay-off device uses a vertical pay-off reel. When in use, the pay-off device is stationary, and the metal cable is pulled upward by the wire drawing machine, so that it slides and rotates along the pay-off reel of the pay-off device and is paid out. The metal cable is wound back and forth layer by layer on the winding shaft of the pay-off reel. There is a certain tension during winding. The metal cable can be tightly arranged on the pay-off reel without loosening, but when the wire is freely released, the metal cable sags and relaxes, and the tension is released, causing the metal cable to shake left and right during the pay-off process. The metal cable has problems such as unstable shaking and large swing amplitude. In addition, in the pay-off device, the metal cable passes through the silencer mechanism above. Due to the above technical problems, the metal cable collides with the silencer mechanism, causing scratches on the surface of the metal cable and generating noise, which affects the quality of the metal cable and makes the staff work in a noisy environment every day.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] like Figure 1 As shown, a wire drawing machine pay-out auxiliary device with a silencer mechanism includes a pay-out auxiliary device 5 and a silencer mechanism, and the silencer mechanism includes a conductor mechanism 3 and a noise reduction mechanism 4. The pay-out auxiliary device 5 is a frame structure, and a pay-out reel 6 is placed in the middle of the pay-out auxiliary device 5. The metal cable 1 is wound on the pay-out reel 6. The end of the metal cable 1 is led out from the pay-out auxiliary device 5 and connected to the pay-out device 2 through the silencer mechanism. After passing through the pay-out device 2, the metal cable 1 is paid out to the wire drawing machine for the wire drawing process. The pay-out device 2 is a prior art; the fixed installation structure of the silencer mechanism is also a prior art, and there are many ways to implement it, which will not be repeated here.

[0031] like Figure 2As shown, the line-laying auxiliary device 5 includes: vertical support legs, a triangular support frame 9, a circular line-laying plate 10 and a cable clamp tube 11. The lower ends of the three vertical support legs are fixedly installed on the ground by anchor bolts. The vertical support legs include an upper square tube column 7 and a lower square tube column 8. The outer tube diameter of the upper square tube column 7 is slightly smaller than the inner tube diameter of the lower square tube column 8, and the upper square tube column 7 can be smoothly inserted into the lower square tube column 8. The tube walls of the upper square tube column 7 and the lower square tube column 8 are both provided with pin holes, and the height adjustment of the vertical support legs can be achieved by adjusting the pins inserted into the pin holes at different positions. The upper end of the upper square tube column 7 is fixedly connected to the triangular vertex position of the triangular support frame 9 by welding, and the vertical support legs and the triangular support frame 9 together constitute the main support frame structure of the line-laying auxiliary device 5. The triangular support frame 9 is composed of three square tubes welded together.

The lower end of the lower square tube column 8 is provided with a protruding horizontal edge. The first through hole is opened on the horizontal edge. The lower end of the lower square tube column 8 is fixed to the ground through the first through hole by the anchor bolt, thereby improving the stability of the wire-laying auxiliary device 5.

The bolt connection method can facilitate the disassembly and assembly of the circular wire-laying plate 10. When placing the wire-laying drum 6, the circular wire-laying plate 10 must be removed first. A circular through hole is opened in the center of the circular wire-laying plate 10, and the metal cable 1 passes through the circular through hole. The circular through hole can be used to initially limit the metal cable 1, which can reduce the noise during wire-laying to a certain extent.

[0032] like Figure 2 , 3 As shown, multiple cable clamps 11 are fixedly mounted on the triangular support frame 9 in a detachable manner in the vertical direction. The cable clamps 11 include: a square plate 13 and a steel pipe 14. The square plate 13 has a certain thickness and can be opened in the thickness direction. The upper end of the steel pipe 14 is welded to the middle position of the lower surface of the square plate 13. The side of the square plate 13 is provided with a tensioning threaded hole. The three square pipes of the triangular support frame 9 are provided with a plurality of second through holes. The square plate 13 is adjusted to an appropriate position according to the diameter of the pay-off drum 6. The tensioning bolt 12 passes through the second through hole of the triangular support frame 9 and is screwed into the tensioning threaded hole to fix the square plate 13 to the square pipe of the triangular support frame 9. The cable clamp 11 further limits the metal cable 1 during the pay-off process, prevents the metal cable 1 from swinging too much during the pay-off process, and further reduces noise.

The upper part of the noise reduction outer shell 25 is integrally formed with a protruding horizontal ring, and the center of the horizontal ring is the outlet 18. The wire mechanism 3 is fixedly installed on the upper surface of the horizontal ring. A plurality of weight reduction holes 21 are evenly distributed on the outer circumference of the noise reduction inner shell 22, and the weight reduction holes 21 are used to reduce the weight of the noise reduction inner shell 22. The inner wall of the noise reduction inner shell 22 is evenly provided with a plurality of sponge pads 23 by bonding, the outer wall of the noise reduction inner shell 22 is evenly provided with a plurality of inner shell columns 26 by welding, the inner wall of the noise reduction outer shell 25 is evenly provided with a plurality of outer shell columns 24 corresponding to the inner shell columns 26 by welding, the outer shell columns 24 and the inner shell columns 26 are fixedly connected with the first buffer spring 20 by welding, and the first buffer spring 20 can play a buffering and vibration reduction role when the noise reduction inner shell 22 contacts the metal cable 1. The wire mechanism 3 includes a wire wheel bracket 17, a wire wheel 15, a buckle 16 and a second buffer spring 19, the wire wheel bracket 17 is an L-shaped plate, the number of wire wheel brackets 17 is four, and they are fixedly installed on the upper surface of the horizontal ring in pairs by bolt connection, and the horizontal plate of the wire wheel bracket 17 is installed on the inner side. A wire wheel 15 is mounted on each wire wheel bracket 17 through a buckle 16, and four wire wheels 15 are arranged up and down in pairs. The wire wheel 15 includes a wire wheel body, a rotating shaft and two parallel horizontal support rods. One end of the horizontal support rod passes through the vertical plate of the wire wheel bracket 17 and is movably mounted on the wire wheel bracket 17 through the buckle 16 in a sliding connection manner. The other end of the horizontal support rod is fixedly connected to the two ends of the rotating shaft. The wire wheel body is rotatably mounted on the rotating shaft. The second buffer spring 19 is mounted on the horizontal support rod located on the inner side of the vertical plate of the wire wheel bracket 17. The wire wheel 15 can slide horizontally relative to the wire wheel bracket 17. When the wire wheel 15 slides under force, the second buffer spring 19 can play a buffering role. At the same time, the second buffer spring 19 can also enable the wire wheels 15 opposite to each other to clamp the metal cable 1. The wire wheel 15 is a nylon wire wheel, and the nylon material has a certain noise reduction effect.

[0034] The method for using the aforementioned wire drawing machine pay-off auxiliary device with a muffler mechanism comprises the following steps:

[0035] First, adjust the height of the vertical support legs to a suitable position, use a forklift to place the pay-off drum 6 in the center of the space enclosed by the vertical support legs and the triangular support frame 9, then slide the cable clamp 11 to the outer edge of the pay-off drum 6, use the tensioning bolts 12 to tighten and fix the cable clamp 11, and fix the circular pay-off plate 10 to the upper surface of the triangular support frame 9 by bolts to assemble a complete pay-off auxiliary device 5. Pass the end of the metal cable 1 through the round through hole in the middle of the circular pay-off plate 10, then pass the metal cable 1 through the upper noise reduction inner shell 22 and into the middle of the two opposing wire wheels 15, and finally introduce the end of the metal cable 1 into the pay-off device 2. After the preparation work for laying out the metal cable 1 is completed, the wire drawing machine can start the wire drawing operation. During the laying out process, the cable clamp tube 11 is used to eliminate the defect of large swinging of the lower metal cable 1, and the round through hole of the circular laying plate 10 performs preliminary positioning of the metal cable 1, which can reduce the initial noise; the metal cable 1 enters the noise reduction inner shell 22 in a spiral shape, and will not make noise when in contact with the sponge pad 23. When the metal cable 1 collides with the noise reduction inner shell 22, the first buffer spring 20 plays a shock-absorbing buffering role. The metal cable 1 is squeezed and straightened after passing through the outlet 18 and two sets of wire wheels 15, and the second buffer spring 19 plays a shock-absorbing buffering role. Through the wire drawing machine laying out auxiliary device with a silencer mechanism, the metal cable 1 can be quickly and smoothly laid out to the wire drawing machine for the wire drawing process.
