[0002] As an important building material, prestressed steel wire is widely used in bridges, buildings, machinery and other fields. In the production and processing of prestressed steel wire, wire drawing machine is one of the indispensable equipment, which can enhance the strength and toughness of steel wire by drawing the steel wire to the required diameter.

[0003] Traditional prestressed steel wire drawing is mostly smooth steel wire drawing. In the design and use of prestressed steel wire for special purposes, it is necessary to ensure the strength of the steel wire while enhancing the bonding force between the steel wire and concrete.

This design enables the processing device to adapt to steel wires of different diameters, thereby improving the versatility and flexibility of the equipment.

[0011] Preferably, in order to realize the driving of the shell, the driving member is a cylinder or a hydraulic cylinder; designing the driving member as a cylinder or a hydraulic cylinder can realize precise position control and ensure the processing accuracy.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] Example 1 This embodiment provides a prestressed steel wire processing device, such as Figure 1-Figure 6As shown, the processing device includes a chassis 1, a steel wire inlet 2 and a steel wire outlet 3 respectively arranged on both sides of the chassis 1, three shells 4 distributed in an annular shape on the side of the steel wire outlet 3 away from the chassis 1 and connected to the steel wire outlet 3, rotating shafts 5 respectively passing through the side of the shell 4 away from the steel wire outlet 3 and rotatably connected to the corresponding shell 4, and guide wheels 6 respectively fixedly sleeved on the three rotating shafts 5 and located on the inner side of the corresponding shell 4 for guiding the steel wire; an indentation groove 61 for indenting the steel wire is arranged on the outer side of the guide wheel 6; the processing device also includes a shell 6 arranged on the chassis 1 and the three shells 4 and connected to the corresponding The rotating shaft 5 is connected to a lubrication structure 8 for lubricating the rotating shaft 5; the lubrication structure 8 includes lubrication cylinders 81 fixedly arranged on the three housings 4 and located at one end of the corresponding rotating shaft 5, a delivery pipe 85 arranged between the three lubrication cylinders 81 for connecting the three lubrication cylinders 81, an oil inlet 82 arranged on one of the lubrication cylinders 81, an oil outlet 83 arranged on another lubrication cylinder 81, and a pipeline structure 84 arranged on the chassis 1 and connected to the oil inlet 82 and the oil outlet 83 for circulating the lubricating oil in the three lubrication cylinders 81, and the rotating shaft 5 is rotatably connected in the lubrication cylinder 81.

[0019] It should be noted that the steel wire is powered by a wire drawing machine in the prior art and is sequentially conveyed to the steel wire inlet 2, the steel wire outlet 3 and the guide wheel 6 for indentation.

[0020] Among them, in order to avoid wire jamming and ensure the quality of processing, the width of the indentation groove 61 is at least larger than the diameter of the steel wire; such a design can not only ensure that the steel wire can pass through the indentation groove 61 smoothly, and will not cause the steel wire to jam or be damaged due to the indentation groove 61 being too narrow, but also can effectively indent the steel wire to ensure the depth and consistency of the indentation.

[0021] During use, when the steel wire is drawn through the wire drawing machine, it enters the steel wire inlet 2 and is output from the steel wire outlet 3 in sequence. During the output process, the steel wire will pass through the guide wheel 6, which will cause the guide wheel 6 to rotate and will also be guided by the guide wheel 6. As the guide wheel 6 rotates under the guidance of the guide wheel 6, the steel wire will be indented along the indentation groove 61. At this time, a depression will be formed on the surface of the drawn steel wire, thereby increasing the roughness and friction of the steel wire surface. In the process of indentation processing of the steel wire, the lubricating oil can be transported to one of the lubricating cylinders 81 through the oil inlet 82 through the pipeline structure 84. When the lubricating oil is in the lubricating cylinder 81, its rotating shaft 5 will be lubricated. Then, the lubricating oil entering the lubricating cylinder 81 will also be transported through the delivery pipe 85 to the other two lubricating cylinders 81 in sequence, and lubricate the rotating shafts 5 in the other two lubricating cylinders 81. Finally, it is discharged through the oil outlet 83 and then refluxed through the pipeline structure 84 for recovery.

[0022] Specifically, the pipeline structure 84 includes a fixing frame 841 fixedly arranged on one side of the chassis 1, an oil inlet pipe 842 and an oil return pipe 845 fixedly arranged on the fixing frame 841, a first connecting pipe 843 whose two ends are respectively fixedly connected and communicated with the oil inlet pipe 842 and the oil inlet port 82, and a second connecting pipe 844 whose two ends are respectively fixedly connected and communicated with the oil outlet port 83 and the oil inlet pipe 842.

[0023] It can be understood that in order to ensure the use of the adjustment structure 7, an end of the oil inlet pipe 842 away from the first connecting pipe 843 and an end of the oil return pipe 845 away from the second connecting pipe 844 are connected to an oil pump, and the lubricating oil in the oil tank for storing the lubricating oil is sucked and transported to the oil inlet pipe 842 by the oil pump, and the lubricating oil flowing through the three lubrication cylinders 81 is then pumped back into the oil tank or other containers through the oil return pipe 845; the setting of the compression spring 72 can provide additional supporting force to ensure the stability of the shell 4 during the processing and prevent displacement due to vibration or impact. At the same time, the design of the locking bolt 721 makes the installation and disassembly of the compression spring 72 more convenient and easy to maintain. Initially, the lubricating oil enters the first connecting pipe 843 through the oil inlet pipe 842, and then flows to the oil inlet port 82 of one of the lubricating cylinders 81 through the first connecting pipe 843 to lubricate the rotating shaft 5 in the lubricating cylinder 81. Then, the excess lubricating oil will flow to the other two lubricating cylinders 81 in sequence through the connection of the delivery pipe 85, and lubricate the rotating shafts 5 in the other two lubricating cylinders 81. After that, the excess lubricating oil will flow to the second connecting pipe 844 through the oil outlet 83, and then flow to the oil return pipe 845 through the second connecting pipe 844, and finally flow back through the oil return pipe 845 for recovery for the next recycling.

[0024] In addition, in order to ensure the lubrication effect of the lubricating oil circulation, a filter is fixedly installed inside the end of the oil inlet pipe 842 close to the second connecting pipe 844; the design of the filter can prevent impurities in the returned lubricating oil from entering the lubrication system, thereby protecting the rotating shaft 5 and the lubrication cylinder 81.

[0025] Furthermore, the processing device also includes an adjustment structure 7 arranged on the chassis 1 and connected to the three shells 4 for adjusting the spacing between the three guide wheels 6. The adjustment structure 7 includes a connecting shaft 71 fixedly arranged on the three shells 4 at one end away from the corresponding guide wheel 6 and hinged to the wire outlet 3, and a driving member 73 arranged on the chassis 1 and hinged at a position above one side of the corresponding connecting shaft 71 of the shell 4 for driving the shell 4 to move and rotate the connecting shaft 71. The driving member 73 is a cylinder or a hydraulic cylinder.

[0026] It can be understood that the adjustment structure 7 also includes a compression spring 72 arranged at the top of the shell 4 and connected to the chassis 1, and both ends of the compression spring 72 are fixedly connected with locking bolts 721. The two ends of the compression spring 72 are respectively fixedly connected to the chassis 1 and the top of the shell 4 through two locking bolts 721.

[0027] Before the processing device starts working, the three shells 4 and the guide wheels 6 thereon are in the initial position. At this time, the compression spring 72 is in a compressed state, providing a certain pre-tightening force for the shell 4. When it is necessary to adjust the spacing between the three guide wheels 6 according to the size of the steel wire, the three driving members 73 can be started. At this time, the three driving members 73 will respectively push the corresponding connected shells 4 to move. Since the connecting shaft 71 connected to the shell 4 is hinged to the steel wire outlet 3, the movement of the shell 4 will cause the connecting shaft 71 to rotate, thereby changing the angle of the shell 4, and then changing the spacing between the guide wheels 6 connected to the three shells 4. In addition, during and after the adjustment, the compression spring 72 will provide a certain support effect to ensure the stability of the shell 4 in use.

[0028] Example 2 Different from Example 1, in order to realize the automation of the device, the processing device also includes a control system, and the driving member 73 is connected to the output end of the control system; by introducing the control system, when in use, it is only necessary to operate the control system to send a start / stop signal to the driving member 73 to realize automatic control of the driving member 73, thereby reducing dependence on operators, reducing the tediousness and errors of manual adjustment, and making the processing process more stable and reliable.

[0029] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
