[0025] like Figures 1 to 9 As shown, the spiral blade forming device of this embodiment is a device for producing spiral blades, which can be used in the field of resource and environmental technology, for example, for supporting the manufacturing process of spiral blades in sludge conveying equipment.

[0026] Specifically, the spiral blade forming device includes a frame guide rail group 10, a blade clamping group, a hydraulic push-pull group 20, a hydraulic station 30 and an electric control box 40.

[0027] The blade clamping group includes a tail swivel clamping group 50 and an end fixed clamping group 60. The tail swivel clamping group 50 and the end fixed clamping group 60 are arranged opposite to each other and are respectively used to clamp the two ends of the spiral blade to facilitate stretching the spiral blade.

[0028] The tail swivel clamping assembly 50 includes a fixed base 51 and a clamping mechanism 52 rotatably mounted on the fixed base 51. The clamping mechanism 52 can rotate about its axis relative to the fixed base 51. The fixed base 51 is mounted at the first end of the longitudinal direction of the frame guide rail assembly 10 and is used to position and install the tail swivel clamping assembly 50. The clamping mechanism 52 is connected to the first end of the spiral blade to allow the first end of the spiral blade to rotate during the forming process, such as the stretching process.

[0029] The end fixing clamping assembly 60 is connected to the second end of the spiral blade and is used to apply force to the second end of the spiral blade. The hydraulic push-pull assembly 20 includes a movable portion, and the end fixing clamping assembly 60 is connected to the movable portion. The movable portion and the end fixing clamping assembly 60 are movable on the frame guide rail assembly 10. The movable portion can drive the end fixing clamping assembly 60 to move, thereby achieving processing such as stretching the spiral blade.

[0030] The hydraulic station 30 is connected to the hydraulic push-pull group 20 to provide hydraulic driving force for the hydraulic push-pull group 20, thereby moving the moving part. The electric control box 40 is connected to the hydraulic station 30 to control the hydraulic station 30 to input hydraulic oil to the hydraulic push-pull group 20.

[0031] The spiral blade forming device of this embodiment can stretch and form the spiral blade to obtain the desired spiral angle. The spiral blade to be formed can be a spiral blade of a certain length that is pre-welded with a C-shaped spiral blade. The tail swivel clamping group 50 of the spiral blade forming device of this embodiment allows the end of the spiral blade to rotate slightly during the forming process, such as stretching, to avoid uneven stress distribution of the spiral blade during the forming process and circumferential offset of some spiral blades, thereby ensuring that the spiral blade group has consistent deformation during the forming process and improving the quality of the spiral blade. The spiral blade is fixed between the tail swivel clamping group 50 and the end fixed clamping group 60 and then stretched without the need for an operator to approach or touch it, which is safe and reliable.

[0032] In some examples, the clamping mechanism 52 includes two first clamps 53 arranged opposite to each other on both sides of the rotation center of the clamping mechanism 52, and the first end of the spiral blade is connected to one of the two first clamps 53. Since the end of the spiral blade is offset relative to the spiral center of the spiral blade, the first clamp 53 is offset relative to the rotation center to better cooperate with the spiral blade, and the spiral blade can be installed on any first clamp 53 according to the position of its end.

[0033] In some examples, the end fixing clamping group 60 includes two second clamps 61 arranged opposite to each other on both sides of the center of the end fixing clamping group 60, and the second end of the spiral blade is connected to one of the two second clamps 61. Since the other end of the spiral blade is offset relative to the spiral center of the spiral blade, the second clamp 61 is offset relative to the center to better cooperate with the spiral blade.

[0034] In some examples, the center of the end fixing clamping assembly 60 is aligned with the rotation center of the clamping mechanism 52 in the length direction of the frame guide rail assembly 10 to facilitate linear stretching of the spiral blade.

[0035] In some examples, the end fixing clamping group 60 also includes a third clamp 62 located in the center of the end fixing clamping group 60, and a clamping portion 21 is provided at the end of the movable portion, and the clamping portion 21 is connected to the third clamp 62, thereby firmly connecting the end fixing clamping group 60 to the movable portion.

[0036] In some examples, the tail swivel clamping assembly 50 further includes a bearing 54 , and the fixed seat 51 and the clamping mechanism 52 are connected via the bearing 54 , thereby making the rotation between the fixed seat 51 and the clamping mechanism 52 smoother.

[0037] In some examples, the hydraulic push-pull group 20 includes a hydraulic cylinder 22, the main body of the hydraulic cylinder 22 is arranged on the frame guide rail group 10, and the moving part includes a push rod 23 of the hydraulic cylinder 22. The push rod 23 of the hydraulic cylinder 22 can be extended and retracted relative to the main body of the hydraulic cylinder 22. The push rod 23 of the hydraulic cylinder 22 is connected to the end fixed clamping group 60, and the spiral blade can be forcefully stretched by the tensile force provided by the hydraulic cylinder 22.

[0038] In some examples, the spiral blade forming device also includes a linear slide 24, the track of the linear slide 24 is set on the frame guide rail group 10, and the slider of the linear slide 24 is connected to the hydraulic cylinder 22, so that the position of the hydraulic cylinder 22 can be adjusted to adapt to spiral blades of different lengths.

[0039] In some examples, the linear slide 24 is electrically driven and connected to the electric control box 40. Alternatively, the linear slide 24 is hydraulically driven and connected to the hydraulic station 30, thereby achieving linear movement of the linear slide 24.

[0040] In some examples, the rack guide rail assembly 10 is formed by riveting and welding channel steel profiles. The rack guide rail assembly 10 has a stable structure, is easy to disassemble and move, and has good ergonomic performance.

[0041] In some examples, the press station 30 is disposed outside the second end of the rack guide rail assembly 10 , and the structural layout is reasonable and compact.

[0042] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
