TECHNICAL FIELD

[0001] The present application relates to a wire feeder for gas heat treatment furnace threading, aiming at more convenient realization of the threading work when the wire position needs to be supplemented in the working state of the gas heat treatment furnace, and belongs to the technical field of metal product processing. BACKGROUND

[0002] The gas heat treatment furnace has a hearth length of 30m, and the temperature during work reaches 1000 DEG C. It is very difficult to pass the steel wire through the hearth during production. Generally, a steel rod with a length of more than 30m is used to pass a steel wire along the hearth wall, and then a lead plate is used to pull the steel wire through the hearth. If one or several wire positions need to be supplemented during production, this method cannot be realized. The traditional wire supplementing method uses a wave plate to pull, but the wave plate pulling can only pass the supporting roller, and the pressing roller needs manual intervention to pass, especially at the lead pot pressing roller, because the blocking occurs below the lead liquid surface and cannot be observed, the processing difficulty is very large, and the success rate of the lead is very low. The present application designs a new type of gas heat treatment furnace wire threading feeder, which uses the friction between the steel wire and the feeder to drive, uses a transverse rhombus design to meet the wire passing demand of the supporting roller and the pressing roller, and solves the problem of blocking of the feeder during pulling. The device is safe and reliable, simple to operate, and can more conveniently complete the threading and lead of the heat treatment furnace. SUMMARY

[0003] The present application solves the problems of inconvenient operation and blocking during the threading process of the existing wire device.

[0010] The specific application of the wire feeder of the application will be further explained below with reference to the accompanying drawings.

[0011] The specific structure of the device for feeding a steel wire in a steel wire heat treatment production line according to the embodiment is shown in the figure, and the device is specifically used in an open flame furnace of a heat treatment phosphating production line and a subsequent lead bath quenching tank connected thereto. Figure 1

[0012] ​A kind of wire feeder for gas heat treatment furnace threading, including main body part, rotating part and wire belt part.The main body part includes two edge wire feeder left plate 2 and wire feeder right plate 3, middle connecting plate 1 and four friction pins 10 are formed.Therein wire feeder left plate 2 and wire feeder right plate 3 adopt transverse diamond shape, so as to pass through the boss in gas furnace and the roller in lead pot and other relatively complex and easily cause to be stuck environment, two edge side plate is symmetric in the middle, stress is uniform, keeps wire belt process stable travel.

[0013] The rotating part includes wire pressing plate 4, rotating rod 5, limiting plate 6.Therein wire pressing plate 4 is equipped with rotatable rotating rod 5, is assembled in main body part, is fixed on traveling steel wire by rotating wire pressing plate 4 and cooperating four friction pins 10, extrudes the steel wire being in travel to friction force and will wire feeder be fixed on traveling steel wire, passes through gas furnace and lead pot with steel wire;Wire pressing plate 4 is opened with wire slot, cooperates limiting plate 6 and is stuck in fixed position with traveling steel wire, prevents steel wire from moving in the process of travel.

[0014] The wire belt part includes steel wire connecting ring 7, steel wire connecting pin rod 8 and steel wire connecting block 9.Three combinations are connected steel wire and can rotate wire belt part, and need to be hanged in steel wire connecting block on the steel wire of traction.

[0015] The limiting plate 6 is a trapezoidal plate, and the width of the top is less than the width of the wire pressing plate 4, and the steel wire is limited in a certain position with the wire pressing plate 4 rotating.

[0016] The steel wire connecting ring 7 is a hollow ring block in the middle, and the side has the hole for the steel wire connecting pin rod 8 to pass through.

[0017] The end cap of the steel wire connecting pin rod 8 is larger in diameter than the rod, passes through the hole of the steel wire connecting ring 7 and is connected with the steel wire connecting block 9, to ensure that it can rotate in the hole.

[0018] The steel wire connecting block 9 is a square block, has the hole for the steel wire to pass through and be hung, and is connected with the steel wire connecting pin rod 8, and can rotate together.

[0019] The working principle of the device is that the device is fixed on two normal running steel wires, uses the normal running steel wires as the traction power, drives the device and the connected steel wire to pass through the open flame furnace and the lead tank. The fixing mode is to use the front and rear friction pins 10 and the rotating wire pressing plate 4 to clamp the steel wire into an arch shape, and to fix the wire feeder on the two running steel wires through friction force and steel wire traction. The left plate 2 and the right plate 3 of the wire feeder adopt a shuttle-shaped structure, which ensures that the wire feeder can form an upward reaction force under the traction of the steel wire when encountering obstacles during the wire passing process, so that the wire feeder is lifted and will not be stuck, and at the same time, through the adjustment of the structure, the symmetric structure is adopted to ensure that the center of gravity of the wire feeder is on the central axis, the force is balanced, and the rotating rod 5 is lengthened, and the steel wire connecting ring 7, the steel wire connecting pin 8 and the steel wire connecting block 9 at the rear are matched to place the overall center of gravity of the wire feeder at the rear end, so that the overall wire feeder advances in line with the running steel wire, avoiding the occurrence of a large angle between the front end of the wire feeder and the running steel wire, thereby avoiding the occurrence of obstacles above or below and causing the wire feeder to be stuck, thereby ensuring the normal progress of the wire passing process.

[0020] When the open flame furnace is restarted or the wire is rethreaded, the steel wire is first threaded through the steel wire connecting block 9, the wire is fixed, then the rotating rod 5 is turned downward, the wire pressing plate 4 is horizontal, then the two residual steel wires or normal running steel wires are placed below the friction pin 10, as shown in Figure 2 , then the rotating rod 5 is turned upward, the wire pressing plate 4 is rotated and pressed in, the steel wire is pressed in the wire groove of the wire pressing plate 4, and the wire feeder is fixed by cooperating with the friction pin 10, as shown in Figure 3 , then the operator releases the wire feeder to enter the open flame furnace and the lead tank with the running steel wire, and the wire groove and the limiting plate 6 are used to prevent the steel wire from moving during the running process. When the wire feeder passes through the lead tank, the operator only needs to knock the rotating rod 5 with an industrial iron clamp to rotate the rotating rod 5 downward, at this time, under the blocking of the wire comb at the rear end of the open flame furnace and the lead tank, the wire feeder will not continue to move forward, at this time, the operator only needs to cut the steel wire at the tail end of the wire feeder, and the wire feeder can be easily taken off with an industrial iron clamp, and the wire passing process of the open flame furnace and the lead tank is completed.
