Description
Technical Field
[0001] The utility model relates to the technical field of wire laying frames, and particularly relates to a linear wire laying frame device for placing heat treatment salt bath wires. Background Art
[0002] During the production in the heat treatment workshop, the wire before the production of the salt bath furnace is in a single bundle state. When multiple bundles are continuously produced, the head and tail need to be connected, resulting in easy winding of the wire during wire laying. After winding, the surface of the wire is easily scratched, causing quality rejection. If the scratches are serious, there are many connection heads or many broken wires, the furnace needs to be stopped for treatment. Each furnace stop takes 8 - 10 days, causing serious problems such as furnace stop, temporary emergency repair, and serious loss of heat treatment production capacity. Content of the Utility Model

BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic structural diagram of the one-line wire rack device. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0013] The one-line wire rack device in this embodiment is a device for storing wire rods and conveying wire rods into the salt bath furnace in front of the heat treatment salt bath heating furnace. As Figure 1 shown, the one-line wire rack device for placing heat treatment salt bath wires in this embodiment includes a horizontally placed rotating shaft. The inside of the rotating shaft is hollow. One end of the rotating shaft is connected to the moving bracket 1, and the other end of the rotating shaft is connected to the support 12 through a pin shaft. A one-line wire rack 9 is provided on the outside of the rotating shaft near the moving bracket 1. The one-line wire rack 9 is used to place the salt bath wire rods to be heated, and the one-line wire rack 9 can rotate along the axis together with the rotating shaft. A first groove is horizontally opened above the one-line wire rack 9. Transmission wheels are provided at both ends (a and b in the figure) inside the first groove. The two transmission wheels are connected by a transmission belt in a transmission manner. A baffle is provided on the transmission belt. In the figure, a and b are the maximum distances that the baffle can move in the groove. The two bundles of salt bath wire rods are separated by the baffle to prevent the wire rods from entangling. The reduction gear 2 is used to control the transmission wheels, and the reduction gear 2 is provided in the first groove.
[0014] A first balance bracket 4 and a second balance bracket 5 are arranged along the axis on the outside of the rotating shaft near the support 12. The first balance bracket 4 and the first balance bracket 5 are at 90 degrees to ensure the balanced rotation of the one-line wire rack 9.
[0015] The one-line wire rack device further includes a hydraulic lifting device 8. The hydraulic lifting device 8 is a lifting hydraulic cylinder and is placed below the one-line wire rack 9. When the one-line wire rack 9 needs to place salt bath wire rods, the hydraulic lifting device 8 is extended to lift the one-line wire rack 9, separating the moving bracket 1 from the one-line wire rack 9. The moving bracket 1 is moved away, the salt bath wire rods are placed on the one-line wire rack 9, and then the moving bracket 1 is put back to its original position and connected to the rotating shaft.
[0016] Furthermore, an oil-impregnated nylon 3 is assembled outside the one-word wire pay-off rack 9, which can prevent the salt-bath wire from being scratched on the one-word wire pay-off rack 9.
[0017] Wire supports are arranged on both the first balance rack 4 and the second balance rack 5, including a first wire support 10 and a second wire support 11. A second groove is opened on one side of the rotating shaft close to the support 12, and a wire wheel 6 is arranged on the second groove. The salt-bath wire passes through the first wire support 10, the second wire support 11 and the wire wheel 6 in sequence and then extends into the rotating shaft, and extends out from the end of the rotating shaft close to the support 12 and passes through the third wire support 7; wherein the third wire support 7 is fixed on the support 12 through a cross plate.
[0018] When producing the heat-treatment salt-bath wire, extend the hydraulic lifting device 8 to jack up the one-word wire pay-off rack 9 to separate the rotating shaft from the moving support 1, move the moving support 1 away, then use a crane to hoist and sleevedly place a whole bundle of wire on the one-word wire pay-off rack 9, then move the moving support 1 back to its original position, install the rotating shaft, pass one end of the salt-bath wire through the first wire support 10, the second wire support 11 and the wire wheel 6 and then extend it into the rotating shaft, and extend out from the end of the rotating shaft close to the support 12 and pass through the third wire support 7, and then sequentially pass through the subsequent active wire feeder, wire guiding device and pre-furnace wire dividing device to gradually feed the wire into the salt-bath furnace for heating and salt-bath treatment. When the wire on the one-word wire pay-off rack 9 is about to be used up, weld the tail of the current wire and the head of the next bundle of wire through a butt welder to achieve the purpose of continuous wire feeding, meeting the requirements of multi-wire and continuous production of the heat-treatment salt-bath furnace without wire breakage. And at the same time, turn on the power supply of the reducer 2, use the conveyor belt to move the partition along the first groove from end a to end b, thereby driving the tail of the previous bundle of wire close to the first wire support 10, sleevedly place the next bundle of wire on the one-word wire pay-off rack 9, and separate the two bundles of wire through the partition to prevent the wire from winding. When the wire on the one-word wire pay-off rack 9 is fed into the heating furnace for heating, the one-word wire pay-off rack 9 and the rotating shaft rotate passively, and the balance rotation of the rotating shaft is ensured through the first balance rack 4 and the second balance rack 5 to eliminate the chaotic winding of the whole bundle of wire during the unwinding process.
[0019] A plurality of one-word wire pay-off rack devices can be symmetrically arranged along the center line of the salt-bath furnace for the heat-treatment salt-bath wire, and the wire can be welded at the head and tail of two bundles of wire through a butt welder beside the wire pay-off rack to achieve continuous production without wire breakage, meeting the requirements of multi-wire and continuous production of the heat-treatment salt-bath furnace.
[0020] By using the one-line wire pay-off rack device in this embodiment, it is possible to meet the continuous production of multiple bundles of wire rods in the heat treatment salt bath furnace without interruption, avoid the entanglement of multiple wire rods caused by uneven pulling or non-straightness of the wire rods during the production of the heat treatment salt bath line, also avoid the surface scratches of the wire rods caused by entanglement, avoid the occurrence of quality problems, and also avoid the occurrence of abnormal situations such as temporary furnace shutdown and temporary emergency repair. Moreover, it meets the multi-line production requirements of the heat treatment salt bath furnace. At present, the production of the heat treatment salt bath line is stable, and the salt bath wire rods are now stably produced with ten wires, reducing the furnace shutdown and emergency repair caused by failures, and reducing the factors leading to accidents caused by temporary emergency repair from the source, ensuring the orderly and normal progress of production, and providing a strong guarantee for the monthly production of 1000 tons of 92Si and 96Si.
