Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, specifically to a device for cutting stainless steel pipes to length. Background Technology

[0002] Stainless steel pipe fittings are a general term for various stainless steel pipe connection parts. They can be divided into different categories according to shape, use, connection method, etc. They are easy to install, high performance, and durable. They are widely used in various pipeline construction and installation, including stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel pipe caps, etc. They need to be cut during processing and use.

[0003] Existing technologies cannot effectively control the cutting distance precisely, resulting in low processing accuracy. Furthermore, the cutting of stainless steel pipes varies depending on their size. Therefore, we propose a fixed-length cutting device for stainless steel pipes. 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 device for stainless steel pipe fittings, which can improve the processing accuracy and control the cutting distance, and can cut stainless steel pipe fittings of different sizes, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length cutting device for stainless steel pipe fittings, comprising a mounting platform, a measuring and cutting unit, a guiding and limiting unit, and a cooling unit;

[0006] Mounting platform: The upper part is equipped with a measuring and cutting unit, a guide and limiting unit, and a cooling unit;

[0007] The measuring and cutting unit includes a limiting groove, a sliding mounting frame, an adjusting screw, a sliding mounting block, a replaceable guide wheel, a motor, a threaded rod, a laser emitter, and a laser receiver. Two limiting grooves are formed at the left and right ends of the upper rear side of the mounting platform. A threaded rod is rotatably connected to the inner side of each limiting groove. Two motors are fixedly connected to the left and right ends of the rear end of the mounting platform. The output shafts of the motors are fixedly connected to one end of the threaded rod. A sliding mounting frame is slidably connected to the inner side of each limiting groove. A sliding mounting block is slidably connected to the inner side of each sliding mounting frame. The inner side of the sliding mounting frame is rotatably connected to the upper and lower ends of the outer side of the adjusting screw. The sliding mounting block is threadedly connected to the adjusting screw. The two sliding mounting blocks are directly rotatably connected to a replaceable guide wheel. A laser emitter and a laser receiver are fixedly connected to corresponding sides of the two adjusting screws, respectively. The motor drives the threaded rod to rotate, which in turn moves the sliding mounting frame along the limiting groove, thereby adjusting the position of the laser emitter and laser receiver. Rotating the adjusting screw moves the sliding mounting block, which in turn adjusts the position of the replaceable guide wheel. The stainless steel pipe is guided by the replaceable guide wheel to stop between the laser emitter and laser receiver, waiting for cutting. The threaded rod can adjust the distance between the laser emitter and laser receiver and the cutting device, thereby precisely controlling the cutting length of the stainless steel pipe. The replaceable guide wheel can be replaced according to different pipe diameters to meet the processing needs of various specifications of pipes.

[0008] Furthermore, the measurement and cutting unit also includes a hydraulic press, a fixed plate, a cutting machine, a laser rangefinder, and a laser receiving plate. The hydraulic press is fixedly connected to the upper front right side of the mounting platform. The fixed plate is fixedly connected to the upper end of the hydraulic press. The cutting machine is fixedly connected to the left end of the fixed plate. The laser rangefinder is fixedly connected to the middle right end of the hydraulic press. The laser receiving plate is fixedly connected to the middle right end of the sliding mounting frame. The hydraulic press moves the fixed plate up and down, thereby driving the cutting machine to cut the stainless steel pipe. The laser rangefinder and laser receiving plate accurately measure the distance between the cutting machine and the laser emitter and receiver, ensuring the accuracy of the cutting length.

[0009] Furthermore, the guiding and limiting unit also includes a first fixed seat, an electric telescopic rod, two replaceable guide wheels, a hydraulic press, an upper fixed plate, and a lower fixed seat. Two first fixed seats are fixedly connected to the left and right ends of the upper front end of the mounting platform. An electric telescopic rod is fixedly connected to the upper end of each of the first fixed seats. Two replaceable guide wheels are rotatably connected between the upper end of the electric telescopic rod and the first fixed seats. A lower fixed seat is fixedly connected to the front upper end of the mounting platform. Two hydraulic presses are fixedly connected to the left and right sides of the front upper end of the mounting platform. An upper fixed plate is fixedly connected to the upper end of each hydraulic press. Anti-slip rubber is provided on the outer sides of the upper fixed plate and the lower fixed seat. The first fixed seats limit the electric telescopic rod, which drives the two replaceable guide wheels to move up and down, guiding stainless steel pipe fittings of different sizes. The two replaceable guide wheels can be replaced as needed. The hydraulic press drives the upper fixed plate to move up and down, cooperating with the lower fixed seat to fix the pipe fitting during cutting and prevent slippage.

[0010] Furthermore, the guiding and limiting unit also includes spring telescopic rods and replaceable guide wheels. Two spring telescopic rods are fixedly connected to the left and right sides of the upper center of the mounting platform, and replaceable guide wheels are rotatably connected to the upper ends of the spring telescopic rods. The spring telescopic rods push the replaceable guide wheels towards the center. The replaceable guide wheels can be replaced according to the pipe size to ensure that the pipe is always in the center position, improving the accuracy of cutting and length measurement.

[0011] Furthermore, the cooling unit also includes a water storage tank, a water pump, a second fixing base, a water collection pool, and a nozzle. A water collection pool is located at the center of the upper front side of the mounting platform, and a water storage tank is located at the center of the lower front side of the mounting platform. The water collection pool and the water storage tank are connected through a filter pipe. A second fixing base is fixedly connected to the left end of the mounting platform, and a nozzle is fixedly connected to the upper end of the second fixing base. The inlet of the water pump is connected to the water storage tank through a pipe, and the outlet of the water pump is connected to the inlet of the nozzle through a pipe. The second fixing base secures the nozzle. The water pump draws cooling water from the water storage tank and delivers it to the nozzle through the pipe to cool the cutting blade and fittings. The water collection pool collects the cooling water, filters it, and returns it to the water storage tank, thus achieving water resource recycling.

[0012] Furthermore, a conveyor belt is included, which is fixedly connected to the middle of the rear end of the mounting platform. The cut pipes fall onto the conveyor belt, which then transports the stainless steel pipes to the outside of the device for subsequent processing.
