Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flute-shaped tube branch cutting, and specifically relates to a flute-shaped tube branch cutting device. Background Technology
[0002] A flute tube is a core structure of an evaporator / condenser, consisting of a thicker main pipe (manifold) and numerous slender branch pipes (commonly called "flute tubes," "flat tubes," or "microchannel tubes") welded parallel to the main pipe. Refrigerant is distributed within the main pipe and flows through these branch pipes for heat exchange. An air conditioning flute tube length cutting device is a specialized piece of equipment used in the air conditioning and refrigeration industry to efficiently and precisely cut the branch pipes on the flute tubes used in the manufacture of evaporators or condensers.
[0003] The air conditioning flute-shaped tube branch pipe length cutting device is a key piece of equipment in the manufacturing of air conditioning heat exchangers. Its core task is to precisely cut microchannel flat tubes to a set length. Modern equipment mainly relies on servo motors and encoders to achieve high-precision length control. However, in practical applications, it cannot cut branch pipes of different diameters simultaneously, and the efficiency of changing branch pipes is low, making it difficult to promote and popularize.
[0004] In summary, there is an urgent need for a new flute-shaped pipe branch cutting device to solve the problem that existing cutting devices cannot cut branch pipes of different diameters simultaneously. Utility Model Content
[0005] This utility model provides a flute-shaped pipe branch cutting device, which aims to solve the problem that existing cutting devices cannot cut branch pipes of different diameters at the same time.
[0006] The present invention is implemented as follows:
[0007] A flute-shaped pipe branch cutting device, comprising:
[0008] The bed frame has a perforated plate fixed at the top. A perforated positioning plate is provided at the top of the bed frame near the outer side of the perforated plate. The perforated positioning plate is fixed to the top of the bed frame with screws. Protective plates are fixed to the bed frame at both ends of the perforated positioning plate. Guide rails are welded inside the protective plates. A slider is fixed at the top of the guide rails. A manual cutting machine is fixed at the top of the slider.
[0009] The lower end of the bed frame is equipped with two rows of fixed brackets, and the fixed brackets are equipped with extendable length positioning rods.
[0010] Furthermore, the fixing frame specifically includes a first fixing frame and a second fixing frame. The first fixing frame and the second fixing frame are provided with a plurality of circular through holes. The length positioning rod is embedded in the circular through holes and can rotate and move freely along the circular through holes.
[0011] Furthermore, each circular through hole of the first fixing bracket is provided with a threaded fixing hole at the bottom, and a fixing bolt is provided in the threaded fixing hole through the thread.
[0012] Furthermore, the front end of the length positioning rod is provided with a positioning baffle, which is fixed to the end of the length positioning rod away from the bed frame by bolts.
[0013] Furthermore, the slider is connected to the slide rail via a sleeve, which is fitted onto the slider and can slide along the slide rail.
[0014] The beneficial effects achieved by this utility model are:
[0015] This invention features a bore positioning plate and a length positioning rod in the bed frame, which makes the flute-shaped tube branch more stable during cutting, preventing shaking and burrs and ensuring a neat cut. A fixing bolt is provided at the bottom of the first fixing frame, which can fix the length positioning rod by pressing. Compared with existing flute-shaped tube cutting devices, this invention is simple to operate, has a lower cost, and can be easily popularized. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] This invention incorporates an aperture positioning plate and a length positioning rod. The aperture positioning plate increases the friction between the flute-shaped tube branches of different diameters and the cutting bed, thereby increasing stability during cutting, preventing wobbling and burrs, and ensuring clean cuts. A positioning plate is fixed to the front end of the length positioning rod, allowing for length adjustment of the flute-shaped tube branches. Since a fixing bolt is located at the bottom of the first fixing frame, the length positioning rod can be fixed by compression, making operation simple, cost-effective, and easy to popularize.
[0023] Reference Figure 1 and Figure 2 In this embodiment of the utility model, a flute-shaped tube branch cutting device 100 is provided, including: a bed frame 101, a hole plate 102 fixed at the upper end of the bed frame 101, a hole positioning plate 103 provided at the upper end of the bed frame 101 near the outer side of the hole plate 102, the hole positioning plate 103 being fixed to the upper end of the bed frame 101 by screws, and guard plates fixed on the bed frame 101 at both ends of the hole positioning plate 103. A guide rail 105 is welded inside the guard plate, a slider is fixed at the upper end of the guide rail 105, and a manual cutting machine 104 is fixed at the upper end of the slider. Specifically, the slider is connected to the guide rail through a sleeve 106, the sleeve 106 is fitted on the slider and can slide along the guide rail.
[0024] The lower end of the bed frame 101 is provided with two rows of fixing frames, and the fixing frames are provided with extendable length positioning rods 107. It should be noted that the fixing frames specifically include a first fixing frame 109 and a second fixing frame 108. The first fixing frame 109 and the second fixing frame 108 are provided with several circular through holes. The length positioning rods 107 are embedded in the circular through holes and can rotate and move freely along the circular through holes.
[0025] At the bottom of each circular through hole in the first fixing frame 109, there is a threaded fixing hole. A fixing bolt is installed in the threaded fixing hole through the thread. When it is necessary to fix the length positioning rod 107, the fixing bolt is moved upward, so that the fixing bolt and the length positioning rod 107 are pressed together, so that the length positioning rod 107 is fixed in the first fixing frame 109.
[0026] The length positioning rod 107 has a positioning baffle 110 at its front end. The positioning baffle 110 is fixed to the end of the length positioning rod 107 away from the bed frame 101 by bolts. The height of the positioning baffle 110 is higher than the horizontal height of the aperture positioning plate 103. The positioning baffle 110 is used to position the flute tube branch. When the flute tube branch needs to be cut, the front end of the flute tube branch is placed against the positioning baffle 110, and then the manual cutting machine 104 cuts it.
[0027] Based on the above structure, the specific usage of this embodiment is as follows: loosen the fixing bolts at the lower end of the first fixing frame 109 so that the length positioning rod 107 can slide freely in the circular through holes of the first fixing frame 109 and the second fixing frame 108, and move the length positioning rod 107 away from the bed frame 101 until the distance between the positioning plate and the manual cutting machine 104 reaches the preset distance. The preset distance can be 3cm, 5cm, 7cm, 10cm, 15cm, etc., and the specific distance can be determined according to the actual length of the flute-shaped tube branch.
[0028] After reaching the preset distance, screw the fixing bolt into the first fixing frame 109 until the fixing bolt presses against the length positioning rod 107, so that the length positioning rod 107 is fixed in the first fixing frame 109. At this time, put different flute-shaped tube branches into the aperture positioning plate 103 one by one according to the tube diameter, so that the front end of the flute-shaped tube branches of different apertures rests against the fixing plate. Start the manual cutting machine 104. The manual cutting machine 104 slides through the flute-shaped tube branches of different apertures to produce a batch of flute-shaped tube branches of different diameters. Repeat the above operation to complete the processing.
