TECHNICAL FIELD

[0001] The utility model relates to the field of wire drawing annealing, especially a copper pole pay-off rack. BACKGROUND

[0002] Wire drawing annealing refers to the process of changing the copper pole used as a cable into a copper wire.

[0003] The copper pole as a raw material is in a spiral shape, or in a ring shape, or in a superimposed state, and so on. This state occupies a small amount of space and is convenient for transportation.

[0004] Before wire drawing, the change amount of the copper pole deflection needs to be controlled to ensure that the axis of the copper pole is close to a straight line. At present, the equipment for realizing this process is a copper pole pay-off rack.

[0005] The stretching capacity of the current copper pole pay-off rack is limited, and the copper pole in a zigzag state cannot be effectively stretched. External equipment is needed to reshape the copper pole in this zigzag state. However, the copper pole in a zigzag state cannot be obtained at present. This copper pole in a zigzag state will affect the subsequent annealing and drawing process and the overall production efficiency. SUMMARY

[0011] The feedback signal output by the travel switch is directly provided to the upper computer, and the upper computer generates a prompt alarm and stops the continuous feeding and stretching of the copper rod after receiving the signal.

[0012] The stretching refers to that the first guide assembly performs a certain shaping on the copper rod passing through the opening, the first guide assembly comprises guide rollers distributed on different planes, each outer periphery of the guide rollers is one side of the opening, the copper rod is dragged into the opening by other equipment, and the part of the copper rod in contact with the guide rollers moves to make the guide rollers rotate following the movement of the copper rod, and the copper rod appears a certain deflection adjustment in the process of contacting the guide rollers, which is the stretching of the copper rod, so that the axis of the copper rod is close to a straight line.

[0013] A reset device is further arranged between the swing device and the frame body, and the reset device is a spring, and the swing device is reset when the pressure on the swing device is lost.

[0023] As Figures 1-5 shown, a copper rod pay-off rack comprises a rack body, and a plurality of first guide assemblies 1 provided on the rack body, the first guide assemblies 1 having openings 1a through which the copper rod passes, characterized in that further comprising a swing device 2 provided on the rack body and a sensor 3 located between the swing device 2 and the rack body, part or all of the first guide assemblies 1 are provided on the swing device 2, the swing device 2 is hinged with the rack body, and is swung towards the rack body under the dragging of the zigzag copper rod 4, and contacts the switch of the sensor 3.

[0024] The utility model has the advantages of:

[0025] The utility model adopts the swing device 2 and the sensor 3, and the swing device 2 further provides the connecting effect of the first guide assembly 1 on the rack body, the copper rod 4 in the partial zigzag state presents a certain included angle, and when contacting the first guide assembly 1, the first guide assembly 1 is also dragged to swing, until the swing device 2 contacts the switch of the sensor 3, thereby, the copper rod 4 in the zigzag state is known in advance through the sensor 3.

[0026] Specifically, the sensor 3 is a travel switch, which is used for detecting the swing travel of the swing device 2, preferably, the travel switch is provided on the swing device 2, of course, the travel switch can also be provided on the rack body, and after the swing device 2 swings to a certain amplitude, the travel switch on the rack body is contacted, and the travel switch is triggered to output a feedback signal.

[0027] The feedback signal emitted by the travel switch is directly provided to the upper computer, after receiving the signal, the upper computer occurs prompt alarm and stops continuing to feed and stretch the copper rod 4.

[0028] The aforementioned stretching refers to the first guide assembly 1 shaping the copper rod 4 passing through the opening 1a. The first guide assembly 1 includes guide rollers 100 distributed on different planes. Each outer peripheral surface of the guide roller 100 is one of the sides of the opening 1a. The copper rod 4 is dragged into the opening 1a by other equipment, and the part of the copper rod 4 that contacts the guide roller 100 moves against the guide roller 100, causing the guide roller 100 to rotate as the copper rod 4 moves. During the contact between the copper rod 4 and the guide roller 100, the copper rod 4 will undergo a certain amount of deflection adjustment. This adjustment is called stretching of the copper rod 4, which makes the axis of the copper rod 4 move closer to a straight line.

[0031] The frame includes a column 51 and a rocker arm 52 rotatably connected to the column 51. The rocker arm 52 is connected to the piston rod of the cylinder 6. The first guide assembly 1 and the swing device 2 are both located on the rocker arm 52. In this embodiment, the rocker arm 52 and the column 51 are provided in two sets. In order to avoid mutual interference, the copper rods 4 in each set are changed by the cylinder 6 to change the position between the rocker arms 52. By increasing the distance between them, interference between the copper rods 4 is avoided.

[0032] The column 51 is also provided with a second guide component 7, which is used to guide the copper rod 4 to move to a designated position. Specifically, the second guide component 7 includes a guide wheel 71 and a guide wheel seat 72. The guide wheel seat 72 is disposed on the column 51, and the guide wheel 71 is rotatably disposed on the guide wheel seat 72.
