Most volute springs can be used to achieve automatic reset within a certain range. The volute spring is the first and important process in spring manufacturing. The precision of the winding has an extremely important effect on the entire manufacturing process, and it basically determines the geometric dimensions and characteristics of the spring and the material utilization rate. At present, volute springs are mainly prepared from fatigue-resistant elastic stainless steel strips. Simply put, a stainless steel strip part is an extended object of an ultra-thin stainless steel plate. During the process of processing it into a volute spring, it is necessary to prevent the stainless steel strip from shifting on the conveyor belt.

[0003] At present, for the anti-deviation mechanism used in the production of stainless steel strips, most use upper and lower rollers to achieve friction anti-deviation transmission. This method has the problem of single anti-deviation. In addition, the anti-deviation mechanism does not involve a cleaning structure for the surface of the steel strip, and hard objects on the surface of the steel strip are likely to cause transmission deformation on the surface of the steel strip, affecting the use.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to in combination Figures 1 - 4, the present utility model provides an anti-deviation device, which is used for transporting a stainless steel belt, and the stainless steel belt can be used in the preparation of coil springs. In this application, the anti-deviation device can be installed at the head and tail of an existing transport device. When the transport device transports the stainless steel belt, the anti-deviation device can assist the stainless steel belt in transportation and deviation correction. It includes a pair of transport frames 1, and a plurality of transport rollers 2 are rotatably connected to the pair of transport frames 1. The transport rollers 2 can provide support for the transportation of the stainless steel belt. Above the center of one of the transport rollers 2, there is an upper pressure roller 3, and the upper pressure roller 3 can roll on the stainless steel belt on the transport roller 2 to guide the transportation of the stainless steel belt in a rolling friction manner, realizing anti-deviation processing in one direction. On the transport frame 1, there is a lifting component 4 for controlling the lifting of the upper pressure roller 3. A brush 31 is mounted on the upper pressure roller 3, and the brush head of the brush 31 can contact the surface of the stainless steel belt, which can clean foreign objects on the surface of the stainless steel belt for the purpose of removing foreign objects on the surface of the stainless steel belt, so as to avoid surface rolling deformation when the stainless steel belt is rolled and transported. The brush 31 and the upper pressure roller 3 are of the same height. The advantage of setting them at the same height is that when the upper pressure roller 3 is adjusted in height, the brush 31 can change in height accordingly. A bidirectional linear drive structure 5 is provided on the pair of transport frames 1, and a pair of limit rotating pipes 6 are detachably connected to the bidirectional linear drive structure 5. The limit rotating pipes 6 can act on both sides of the stainless steel belt by rolling friction, so as to improve anti-deviation limit in two directions.

[0022] Bearing seats one 7 are provided at both shaft ends of the transport roller 2, and the transport roller 2 is rotatably connected to the transport frame 1 through the bearing seats one 7. A rotating motor 8 is fixedly connected to one of the bearing seats one 7, and the output end of the rotating motor 8 is fixedly connected to the shaft end of one of the transport rollers 2. Such a setting can stably position the rotation of the transport roller 2 on the transport frame 1.

[0023] A fixed arm 14 is fixedly connected to each transport frame 1. The lifting component 4 includes a lifting screw rod 41 threadedly connected to one of the fixed arms 14, a hand wheel one 42 fixedly connected to one end of the lifting screw rod 41, and a rotating member 43 provided at the other end of the lifting screw rod 41. In this application, the rotating member 43 can adopt a bearing fitting.

[0024] Bearing seats two 9 are rotatably connected to both shaft ends of the upper pressure roller 3. The lifting screw rod 41 is rotatably connected to one of the bearing seats two 9 through the rotating member 43. A sliding rod 10 is fixedly connected to the other bearing seat two 9, and the sliding rod 10 is slidably connected to the other fixed arm 14. The sliding rod 10 penetrates through the fixed arm 14 and realizes a sliding connection.

[0025] Specifically, by rotating the first handwheel 42, the lifting lead screw 41 acts on the fixed arm 14 through threads and can descend. The lifting lead screw 41 is rotatably connected to a second bearing block 9 through a rotating member 43, and the sliding rod 10 penetrates through the fixed arm 14 and is slidably connected. In this way, the upper pressure roller 3 can be lifted and lowered through the second bearing block 9 to control the descent of the upper pressure roller 3 and make it fit on the stainless steel belt of the conveying roller 2. Thus, the upper pressure roller 3 can roll on the stainless steel belt of the conveying roller 2 to conduct transmission guidance on the stainless steel belt in a rolling friction manner, achieving anti-deviation treatment in one direction.

[0026] A bracket 13 is fixedly connected to each second bearing block 9, and a brush 31 is fixedly connected to a pair of brackets 13. By arranging the brush 31 on one side of the upper pressure roller 3 and setting the height of the brush 31 lower than that of the upper pressure roller 3, when the stainless steel belt is conveyed, the brush 31 can clean foreign matters on the surface of the stainless steel belt for the purpose of removing foreign matters on the surface of the stainless steel belt, so as to avoid surface rolling deformation when the stainless steel belt is roll-conveyed.

[0027] The bidirectional linear drive structure 5 includes a bottom plate 51 fixedly connected to a pair of conveying frames 1, a bidirectional lead screw 52 rotatably connected to the bottom plate 51 through bearings, a second handwheel 53 fixedly connected to one end of the bidirectional lead screw 52, a pair of sliding seats 54 threadedly connected to the bidirectional lead screw 52, and a smooth rod 55 fixedly connected to the bottom plate 51. Both sliding seats 54 are slidably connected to the smooth rod 55. In this application, the bidirectional lead screw 52 is a rod structure with a bidirectional thread.

[0028] Specifically, by rotating the second handwheel 53, it can drive the bidirectional lead screw 52 to rotate. With the double-thread setting on the bidirectional lead screw 52 and the guiding effect of the smooth rod 55 on the sliding seats 54, the pair of sliding seats 54 can perform linear motion of approaching or separating from each other. In this way, the distance between a pair of limiting rotating pipes 6 can be adjusted to adapt to the width of the stainless steel belt for rolling friction limiting at both sides. During the transmission of the stainless steel belt, the rolling contact between both sides of the stainless steel belt and the limiting rotating pipes 6 can make the limiting rotating pipes 6 rotate on the mounting rod 12.

[0029] An assembly seat 11 is fixedly connected to each sliding seat 54. An installation rod 12 is threadedly connected to the assembly seat 11. The limiting rotating pipe 6 is rotatably connected to the installation rod 12 through a bearing. One end of the installation rod 12 is provided with a threaded head structure, and a threaded groove adapted to the threaded connection of the threaded head is provided on the assembly seat 11. The threaded connection mode of the installation rod 12 can meet the detachable property of the limiting rotating pipe 6, so as to facilitate the replacement of the limiting rotating pipe 6.
