[0016] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0017] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0018] like Figures 1-4 As shown, the automatic post-processing and screening system for C-shaped spring sheets after forming includes a vibrating material sorting tray 1, a heat treatment oven 2, a cooling device 3, a screening device 4, a qualified product collecting device 5 and a defective product collecting device 6. The feed end of the vibrating material sorting tray 1 is fixedly connected to the discharge end of the forming device 7 of the C-shaped spring sheet 10, and a guide rod 8 inclined downward is extended from the discharge end of the vibrating material sorting tray 1. The guide rod 8 is sequentially passed through the heat treatment oven 2 and the cooling device 3. The screening device 4 includes a vertical screening channel 4.1 and a bucket-shaped feeding channel 4.2 arranged above the vertical screening channel 4.1. The vertical screening channel 4.1 is a flat channel structure with uniform thickness and wide upper and narrow lower width. The width of the narrow part is adapted to the width of the C-shaped spring sheet 10. The thickness of the flat channel should be adapted to the qualified thickness of the C-shaped spring sheet 10, and the qualified product collecting device 5 is located below the flat channel; the upper position of the narrow side of one side of the flat channel is also connected to a defective product discharge channel 9 inclined downward, and the defective product collecting device 6 is located below the defective product discharge channel 9. A horizontal push plate 11 is also provided on the narrow side of the other side of the flat channel, at a position opposite to the inlet of the defective product discharge channel 9. The horizontal push plate 11 is driven by a cylinder 12 to achieve left and right movement. A photoelectric detection head 13 for detecting a stuck C-shaped spring sheet 10 is also provided on the inner wall of the flat channel, next to the horizontal push plate 11. The end of the guide rod 8 is located above the feed channel 4.2 of the screening device 4.

[0019] The cooling device 3 is a wind cooling device.

[0020] The end of the material guide rod 8 is a curved downward arc transition structure.

[0021] The vertical screening channel 4.1 on the screening device 4 is partially a detachable structure or a structure with adjustable width and thickness, so as to meet the screening of C-shaped spring sheets 10 of different sizes or different requirements. When the vertical screening channel 4.1 on the screening device 4 is partially a detachable structure, when the screening of C-shaped spring sheets of different sizes or thicknesses is required, the corresponding size of the vertical screening channel 4.1 that meets the screening is replaced to realize the screening; when the vertical screening channel 4.1 on the screening device 4 is partially a structure with adjustable width and thickness, the width and / or thickness thereof is directly adjusted, so as to flexibly meet the screening of C-shaped spring sheets 10 of different sizes or different requirements.

[0022] When the vertical screening channel 4.1 on the screening device 4 is partially a structure with adjustable width and thickness, the vertical screening channel 4.1 is enclosed by four plates in turn, and the four plates are respectively a first plate, a second plate, a third plate and a fourth plate. The first plate and the third plate are fixed plates, and the second plate and the fourth plate are movable plates that can be close to or away from the first plate and the third plate respectively. Thus, by adjusting the positions of the second plate and the fourth plate, the width and thickness of the vertical screening channel 4.1 can be adjusted.

[0023] Working process:

[0024] After the C-shaped spring sheet 10 is formed, it is sent out from the material guide rod connected to the vibration material sorting disc 1 after being sorted by the vibration material sorting disc 1, and then is subjected to on-demand heating of the heat treatment oven 2 and on-demand cooling of the cooling device 3 in turn, so as to complete the quenching and tempering treatment after forming. Then, the C-shaped spring sheet 10 that has completed the quenching and tempering treatment is continuously sent into the screening device 4 for screening.

[0025] During the screening, because the vertical screening channel 4.1 on the screening device 4 is a flat channel structure that is uniform in thickness and wide at the top and narrow at the bottom in width, and the width of the narrow part of the flat channel is adapted to the width of the C-shaped spring sheet 10, and the thickness of the flat channel is adapted to the qualified thickness of the C-shaped spring sheet 10, only the C-shaped spring sheet 10 that is qualified in width and thickness can smoothly pass through the vertical screening channel 4.1 of the screening device 4 and fall into the qualified product collecting device 6 below for collection, and the C-shaped spring sheet 10 that is not qualified in width or thickness will be stuck on the upper part of the flat channel. When the photoelectric detection head 13 detects that a product stays in the flat channel for a certain time, it will be fed back, and then the horizontal push plate 11 will act to push it into the defective product discharge channel 9 to realize the rejection, and the defective product will be recycled by the defective product collecting device 6.

[0026] The automatic post-treatment and screening system for the C-shaped spring sheet after forming is characterized by ingenious structure, improved product quality, ensured delivery precision, improved production efficiency, greatly shortened production cycle, and more flexible meeting of different customers' processing requirements, especially when the vertical screening channel part of the screening device is of a structure with adjustable width and thickness, the screening requirement can be better met, and the automatic post-treatment and screening system for the C-shaped spring sheet after forming is practical and worth promoting.

[0027] The utility model is not limited to the foregoing specific embodiments. The utility model extends to any new feature or any new combination disclosed in the specification, and any new method or process step or any new combination disclosed.
