Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing technology, specifically a fixed-length cutting mechanism for a corrugated pipe rolling machine. Background Technology

[0002] A corrugated pipe rolling machine is a specialized forming equipment for the efficient and continuous production of metal corrugated pipes. Its core function is to process metal strips into circular corrugated pipes with regular crests and troughs in a single operation through precise rolling, forming, welding, and corrugation processes. Compared to traditional segmented manufacturing processes, the rolling machine significantly improves production efficiency, product consistency, and material utilization, and can produce ultra-long continuous corrugated pipe sections. The corrugated pipes produced, with their excellent flexibility, fatigue resistance, pressure resistance, and displacement compensation capabilities, are widely used in automotive exhaust systems, industrial heat exchangers, petrochemical pipeline compensators, HVAC piping, instrument protective sleeves, and hydraulic and pneumatic systems, among many other fields. It is an indispensable manufacturing equipment for flexible connections and compensation components in modern industrial piping systems.

[0003] Corrugated pipe rolling machines typically have a cutting mechanism at the front end. A hydraulic or pneumatic cylinder drives an electric saw to rotate and descend, cutting the corrugated pipe. The cutting position is usually set at the front end of the guide rail where the corrugated pipe is placed. Due to the lack of support, the stability of the corrugated pipe cutting is poor, and the cut is not very smooth. At the same time, the electric saw is exposed, which poses a certain danger. Therefore, we propose a fixed-length cutting mechanism for corrugated pipe rolling machines. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fixed-length cutting mechanism for a corrugated pipe rolling machine. By clamping and fixing the front and rear ends of the corrugated pipe, the cutting is more stable and the cut is smoother. At the same time, the hidden saw blade is safer and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length cutting mechanism for a corrugated pipe rolling machine, comprising a support table, a lifting and cutting mechanism, and a clamping mechanism; Support table: The upper end of the support table is fixedly connected to an outer cover, and the front end of the support table is equipped with a guide rail; Lifting and cutting mechanism: It includes a saw blade, a base and a cylinder. The cylinder is fixedly connected to the inner rear wall of the outer cover through a mounting seat. The lower end of the cylinder's telescopic end is fixedly connected to the base. The front end of the base is fixedly connected to a protective cover. The middle part of the protective cover is rotatably connected to the saw blade through a rotating shaft. The air inlet of the cylinder is connected to the air outlet of an external air pump. Clamping mechanism: It includes a support column, a triangular clamping plate and a fixed base. The support columns are evenly arranged on the left and right ends of the front and rear sides of the base. The rear support columns are all fitted with the base. The lower end of the support column is connected to the fixed base by bolts. The inner sides of the two adjacent fixed bases are fixedly connected with triangular clamping plates. By clamping and fixing the front and rear ends of the corrugated pipe, the cutting is more stable and the cut is smoother. At the same time, the concealed saw blade is safer.

[0006] Furthermore, the lifting and cutting mechanism also includes a sliding column and a sleeve. The sleeve is fixedly connected to the left and right ends of the top wall of the outer cover, and the sliding column is symmetrically fixedly connected to the left and right ends of the base. The upper end of the sliding column is slidably connected to the inside of the adjacent sleeve, making the lifting and lowering of the base more stable.

[0007] Furthermore, the lifting and cutting mechanism also includes a motor, which is fixedly connected to the rear side of the base. The input end of the motor is electrically connected to the output end of the corrugated pipe rolling machine controller, driving the saw blade to rotate.

[0008] Furthermore, the clamping mechanism also includes guide plates and connecting plates. The guide plates are evenly distributed on the left and right ends of the front and rear sides of the base. The two rear guide plates are fixedly connected to the left and right ends of the upper surface of the base. A connecting plate is fixedly connected between two adjacent front and rear guide plates. A guide groove is provided in the middle of each guide plate. A pin is provided at the upper end of each support column. The pin is slidably connected to the inside of the adjacent guide groove to guide the support column.

[0009] Furthermore, the clamping mechanism also includes two sliding columns, which are fixedly connected to the front and rear ends of the left and right side walls of the outer cover, respectively. The pillars on the same front and rear sides are slidably connected between two adjacent sliding columns, making the sliding of the pillars more stable.

[0010] Furthermore, the clamping mechanism also includes adjustment grooves, which are evenly distributed on the upper end of the fixed base. The bolts that fix the fixed base are located inside the adjacent adjustment grooves to adjust the position of the fixed base.

[0011] Furthermore, a clamping block is inserted into the right side wall of the guide rail, and a bracket is fixedly connected to the upper surface of the clamping block. An optical fiber amplifier is fixedly connected to the upper end of the bracket. The optical fiber amplifier is vertically aligned with the bottom wall of the guide rail. The optical fiber amplifier is bidirectionally electrically connected to the corrugated pipe winding machine controller to detect the position of the corrugated pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The fixed-length cutting mechanism of this corrugated pipe winding machine has the following advantages: 1. When cutting the corrugated pipe, the cylinder drives the saw blade to descend. Through the guide groove of the guide plate, the entire assembly consisting of the support column, triangular clamp, and fixed seat slides towards the corrugated pipe. The triangular clamp first clamps the front and rear ends of the corrugated pipe, and the saw blade continues to descend to achieve cutting. The corrugated pipe is fixed, the vibration is greatly reduced, and the cut is smoother.

[0013] 2. The saw blade, base, and motor are integrated inside the outer casing. The concealed saw blade improves cutting safety, and the outer casing is located at the upper end of the corrugated pipe cutting position, reducing the amount of debris adhering to the inside of the outer casing during cutting.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This embodiment provides a technical solution: a fixed-length cutting mechanism for a corrugated pipe rolling machine, including a support table 1, a lifting cutting mechanism 3 and a clamping mechanism 4; Support table 1: An outer cover 2 is fixedly connected to its upper end.

The lifting and cutting mechanism 3 includes a saw blade 31, a base 32, and a cylinder 34. The cylinder 34 is fixedly connected to the inner rear wall of the outer cover 2 via a mounting base. The lower end of the telescopic end of the cylinder 34 is fixedly connected to the base 32. The front end of the base 32 is fixedly connected to a protective cover. The middle part of the protective cover is rotatably connected to the saw blade 31 via a rotating shaft. The air inlet of the cylinder 34 is connected to the air outlet of an external air pump. The lifting and cutting mechanism 3 also includes a motor 33. The motor 33 is fixedly connected to the rear side of the base 32. The input end of the motor 33 is electrically connected to the output end of the corrugated pipe rolling machine controller. When cutting, the telescopic end of the cylinder 34 extends, causing the entire assembly of the saw blade 31, the base 32, and the motor 33 to descend. The output shaft of the motor 33 drives the saw blade 31 to rotate, cutting the corrugated pipe. The lifting and cutting mechanism 3 also includes a sliding column 35 and a sleeve 36. The sleeve 36 is fixedly connected to the left and right ends of the top wall of the outer cover 2, and the sliding column 35 is symmetrically fixedly connected to the left and right ends of the base 32. The upper end of the sliding column 35 is slidably connected to the inside of the adjacent sleeve 36. The sliding column 35 slides down synchronously inside the adjacent sleeve 36, making the descent process of the base 32 more stable. Clamping mechanism 4: It includes support columns 43, triangular clamping plates 45, and fixed seats 46. The support columns 43 are evenly distributed on the left and right ends of the front and rear sides of the base 32. The rear support columns 43 are all fitted with the base 32. The lower end of each support column 43 is bolted to the fixed seat 46. The inner sides of two adjacent fixed seats 46 are fixedly connected to the triangular clamping plates 45. Clamping mechanism 4 also includes guide plates 41 and connecting plates 42. The guide plates 41 are evenly distributed on the left and right ends of the front and rear sides of the base 32. The two rear guide plates 41 are fixedly connected to the left and right ends of the upper surface of the base 32. The two adjacent guide plates 41 are fixedly connected to the connecting plates 42. The middle of each guide plate 41 is provided with a guide groove 9. The upper end of each support column 43 is provided with a pin. The pin is slidably connected to the inside of the adjacent guide groove 9. Clamping mechanism 4 also includes a sliding column 44. The support columns 44 are fixedly connected to the front and rear ends of the left and right side walls of the outer cover 2, respectively. The support columns 43 on the same side are slidably connected between two adjacent sliding columns 44. The two rear guide plates 41 move synchronously with the base 32. The front guide plate 41 and the adjacent rear guide plate 41 are connected by the connecting plate 42 to form a whole, realizing the synchronous movement of the four guide plates 41. The guide groove 9 is a track that first moves obliquely upward and then vertically upward towards the motor 33. The support columns 43 slide between two adjacent sliding columns 44. The pins of the support columns 43 are slidably connected to the interior of the adjacent guide grooves 9, realizing that the support columns 43 move towards the motor 33 and then stop at the designated position. Then the triangular clamp 45 and the fixed seat 46 move synchronously with the support columns 43 to clamp the corrugated pipe. After the corrugated pipe is clamped, the saw blade 31 continues to descend, and the support columns 43 remain in place for cutting. The clamping mechanism 4 also includes an adjustment groove 47, which is evenly arranged on the upper end of the fixed seat 46. The bolts that fix the fixed seat 46 are located inside the adjacent adjustment grooves 47. The installation position of the fixed seat 46 can be adjusted through the adjustment grooves 47 to accommodate the clamping of corrugated pipes of different diameters within the adjustment range of the adjustment grooves 47.

[0018] The working principle of the fixed-length cutting mechanism of the corrugated pipe rolling machine provided by this utility model is as follows: The fixed-length cutting mechanism of this corrugated pipe rolling machine is placed at the front end of the corrugated pipe rolling machine, and the corrugated pipe processed by the processing mechanism of the corrugated pipe rolling machine enters the guide rail 5 through the lower end of the outer cover 2. When the front end of the corrugated tube moves to the lower end of the fiber optic amplifier 8, the intensity of the optical signal detected by the fiber optic amplifier 8 changes. The fiber optic amplifier 8 feeds back the position information of the corrugated tube to the corrugated tube winding machine controller. The corrugated tube winding machine controller controls the corrugated tube winding machine processing mechanism to stop running and then cuts. The clamping block 6 is fixed to the right side wall of the guide rail 5 by the positioning bolt. After the positioning bolt is loosened, the clamping block 6 can slide on the right side wall of the guide rail 5 to realize the position adjustment of the fiber optic amplifier 8, which facilitates the adjustment of the cutting length of the corrugated tube. When cutting, the telescopic end of the cylinder 34 extends, causing the entire assembly consisting of the saw blade 31, base 32, and motor 33 to descend. The output shaft of the motor 33 drives the saw blade 31 to rotate, cutting the corrugated pipe. The sliding column 35 slides down synchronously inside the adjacent sleeve 36, making the descent process of the base 32 more stable; The two rear guide plates 41 move synchronously with the base 32. The front guide plate 41 and the adjacent rear guide plate 41 are connected by the connecting plate 42 to form a whole, realizing the synchronous movement of the four guide plates 41. The guide groove 9 is a track that first moves obliquely upward and then vertically upward towards the motor 33. The support column 43 slides between two adjacent sliding columns 44. The pins of the support column 43 are slidably connected to the interior of the adjacent guide groove 9, so that the support column 43 moves towards the motor 33 and then stops at the designated position. Then the triangular clamp 45 and the fixed seat 46 move synchronously with the support column 43 to clamp the corrugated pipe. After the corrugated pipe is clamped, the saw blade 31 continues to descend, and the support column 43 remains in place for cutting. The installation position of the fixing seat 46 can be adjusted by adjusting the groove 47 to accommodate the clamping of corrugated pipes of different diameters within the adjustment range of the adjusting groove 47. After the triangular clamp 45 clamps the corrugated pipe, manually shaking the corrugated pipe without any shaking indicates that the adjustment is in place.

[0019] It is worth noting that the fiber amplifier 8 disclosed in the above embodiments can be an F-series diffuse reflection fiber amplifier, and the motor 33 and cylinder 34 can be freely configured according to the actual application scenario. The corrugated pipe winding machine controller controls the operation of the fiber amplifier 8, motor 33 and external air pump using methods commonly used in the prior art.
