Description

Technical Field

[0001] This utility model specifically relates to the field of building steel pipe cutting technology, and specifically to an automatic cutting machine for building steel pipe processing. Background Technology

[0002] Steel pipes, as an indispensable building material, are widely used in various construction projects. Before use, steel pipes need to be cut to process them into specific lengths and shapes that meet the needs of various buildings, satisfying the requirements of different building structures and construction processes. Precisely cut steel pipes can ensure the dimensional accuracy of building structures, improve construction quality, and reduce installation problems and safety hazards caused by dimensional deviations. Moreover, reasonable cutting processes can also improve the utilization rate of steel pipes, reduce material waste, and save construction costs.

[0003] However, in actual use, workers need to use tools such as tape measures and calipers to mark the cutting position on the steel pipe, and then manually align the steel pipe with the cutting point. Due to the influence of manual reading deviation, marking offset, and tilting of the steel pipe, the cutting accuracy of the steel pipe is low and the error is large. Moreover, it is necessary to judge whether the end of the steel pipe is in place by visual inspection. During the cutting process, the end of the steel pipe is prone to shaking due to hand tremors and visual deviation, which ultimately results in the cutting surface deviating from the expected position, resulting in poor cutting accuracy and affecting the subsequent use accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cutting machine for processing building steel pipes. The cutting length of the steel pipe is adjusted by a length adjustment frame on the steel pipe positioning and cutting seat. A sliding trigger plate, which can slide on the steel pipe positioning and cutting seat, positions the end of the steel pipe. When the steel pipe reaches the cutting position, the sliding trigger plate contacts the length adjustment frame. Finally, an electric push rod drives the cutting machine's swing frame to swing downwards, automatically cutting the steel pipe. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

An end positioning plate is fixedly connected to the other end of the limit slide rod, and the end positioning plate is fixedly connected to the top of the extension auxiliary plate.

[0012] A length adjustment frame is movably connected between the two limiting slide rods. The length adjustment frame has a mounting plate, and the limiting slide rods pass through both ends of the mounting plate. Furthermore, a locking bolt is threaded into the connection between the mounting plate and the limiting slide rod.

[0013] The T-shaped sliding frame has sliding holes on both sides, and the limiting slide rod passes through the sliding holes and slides with the T-shaped sliding frame. A limit switch is also embedded on the side of the mounting plate closest to the T-shaped sliding frame.

[0014] The mounting slide is located between the T-shaped sliding frame and the end positioning plate, while the threaded extension rod slides in conjunction with the adjusting groove, and the side of the locking nut is in contact with the side of the T-shaped sliding frame.

[0015] As a further technical solution of this utility model, the above is described.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the locking bolts at both ends of the mounting slide are loosened, and then the position of the mounting slide on the limit slide rod is adjusted according to the required length of the steel pipe to be cut. During cutting, the steel pipe will push the sliding trigger plate to move until one side of the sliding trigger plate contacts the side of the mounting slide.

Finally, the side of the T-shaped sliding frame presses and triggers the limit switch. Moreover, by loosening the locking nut, the height position of the conical positioning tip on the side of the T-shaped sliding frame can be adjusted, thereby supporting and positioning steel pipes of different diameters, preventing the end of the steel pipe from shaking up and down during cutting, and thus improving the cutting accuracy of the steel pipe.

[0019] 3. In this utility model, the steel pipe is placed in the V-groove at the top of the V-groove seat. The V-groove is used to position the steel pipe to prevent displacement after the cutting position is subjected to force. The cutting machine drive motor at the end of the cutting machine swing frame drives the cutting saw blade to rotate. The cutting machine swing frame also drives the cutting saw blade to move downward to the inside of the saw blade groove. This ensures that while cutting the steel pipe, the V-groove also positions the cutting position of the steel pipe. The sliding trigger plate further improves the cutting accuracy of the steel pipe.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0031] Please see Figure 1-8 This utility model provides an automatic cutting machine for processing building steel pipes, including a cutting machine base 1, a cutting machine swing frame 2 above the cutting machine base 1, one end of the cutting machine swing frame 2 is movably connected to a fixed ear plate 12 welded to the end of the cutting machine base 1 by a pin, and the other end is fixedly connected to a cutting machine drive motor 6, and a cutting saw blade 4 is fixedly connected to the output shaft end of the cutting machine drive motor 6.

[0032] The top of the cutting machine base 1 is also fixedly connected to a steel pipe positioning cutting seat 8 for positioning the steel pipe, and a sliding trigger plate 9 is also movably connected to the steel pipe positioning cutting seat 8.

[0033] Furthermore, the steel pipe positioning and cutting seat 8 has a V-shaped groove seat 81 that is fixedly connected to the cutting machine base 1, and the V-shaped groove seat 81 is located below the cutting saw blade 4. The top of the V-shaped groove seat 81 is also provided with a V-shaped groove, and the V-shaped groove seat 81 is also provided with a saw blade slot 82 corresponding to the cutting saw blade 4.

[0034] By adopting the above technical solution, the steel pipe is placed in the V-groove at the top of the V-groove seat 81. The V-groove is used to position the steel pipe to prevent displacement after the cutting position is subjected to force. The cutting machine drive motor 6 at the end of the cutting machine swing frame 2 drives the cutting saw blade 4 to rotate. The cutting machine swing frame 2 also drives the cutting saw blade 4 to move downward to the inside of the saw blade slot 82. This ensures that while cutting the steel pipe, the V-groove is used to position the cutting position of the steel pipe. The sliding trigger plate 9 further improves the cutting accuracy of the steel pipe.

[0035] Furthermore, an extension auxiliary plate 7 is fixedly connected to the side of the cutting machine base 1. A limiting slide rod 83 is symmetrically fixedly connected to the side of the V-shaped groove seat 81 near the extension auxiliary plate 7. An end positioning plate 84 is fixedly connected to the other end of the limiting slide rod 83, and the end positioning plate 84 is fixedly connected to the top of the extension auxiliary plate 7.

[0036] More specifically, a length adjustment frame 85 is movably connected between the two limiting slide rods 83. The length adjustment frame 85 has a mounting plate 851, and the limiting slide rods 83 pass through both ends of the mounting plate 851 respectively. Furthermore, a locking bolt 853 is threadedly engaged at the connection between the mounting plate 851 and the limiting slide rods 83.

[0037] Furthermore, the sliding trigger plate 9 includes a T-shaped sliding frame 91, with sliding holes 92 on both sides of the T-shaped sliding frame 91, and a limiting slide rod 83 passing through the sliding holes 92 and slidingly engaging with the T-shaped sliding frame 91. A limit switch 852 is also embedded on the side of the mounting plate 851 near the T-shaped sliding frame 91.

[0038] By adopting the above technical solution, the locking bolts 853 at both ends of the mounting slide plate 851 are loosened, and then the position of the mounting slide plate 851 on the limit slide rod 83 is adjusted according to the required length of the steel pipe to be cut. During cutting, the steel pipe will push the sliding trigger plate 9 to move until one side of the sliding trigger plate 9 contacts the side of the mounting slide plate 851. The sliding trigger plate 9 will press the limit switch 852, thereby energizing the electric push rod 10 and driving the end of the cutting machine swing frame 2 to swing downward, so as to realize the automatic cutting of the steel pipe.

[0039] More specifically, an adjustment groove 93 is provided above the T-shaped sliding frame 91. A conical positioning tip 94 and a locking nut 96 are respectively provided on both sides of the adjustment groove 93. The conical positioning tip 94 is provided with a threaded extension rod 95 on the side near the locking nut 96, and the threaded extension rod 95 passes through the adjustment groove 93 and is threadedly engaged with the locking nut 96.

[0040] Furthermore, the cutting machine base 1 is provided with an installation groove 11, and an electric push rod 10 is provided between the cutting machine swing frame 2 and the cutting machine base 1. One end of the electric push rod 10 is movably connected to the installation groove 11 by a pin, and the other end is movably connected to the cutting machine swing frame 2 by a shaft.

[0041] Furthermore, the mounting slide plate 851 is located between the T-shaped sliding frame 91 and the end positioning plate 84, while the threaded extension rod 95 is slidably engaged with the adjusting slide groove 93, and the side of the locking nut 96 is in contact with the side of the T-shaped sliding frame 91.

[0042] By adopting the above technical solution, the end of the steel pipe is fitted onto the conical surface of the conical positioning tip 94. The conical surface of the conical positioning tip 94 positions the end of the steel pipe. At the same time, when the steel pipe moves to one side, it pushes the T-shaped sliding frame 91 to move to the side. Finally, the side of the T-shaped sliding frame 91 presses and triggers the limit switch 852. Moreover, by loosening the locking nut 96, the height position of the conical positioning tip 94 on the side of the T-shaped sliding frame 91 can be adjusted, thereby supporting and positioning steel pipes of different diameters, preventing the end of the steel pipe from shaking up and down during cutting, and thus improving the cutting accuracy of the steel pipe.

[0043] Furthermore, the limit switch 852 and the electric push rod 10 are electrically connected by a wire. When the T-shaped sliding frame 91 is in contact with the mounting plate 851, the limit switch 852 is pressed, thereby controlling the electric push rod 10 to be powered on and retracted, thereby causing the electric push rod 10 to drive the cutting machine swing frame 2 to move downward.

[0044] Furthermore, an auxiliary handle 5 is fixedly connected to one end of the cutting machine swing frame 2 near the cutting machine drive motor 6, and there are two button switches on the auxiliary handle 5, one of which can control the cutting machine drive motor 6 to be powered on, so that the cutting machine drive motor 6 drives the cutting saw blade 4 to rotate and cut the steel pipe.

[0045] Another button switch on the auxiliary handle 5 can control the electric push rod 10 to move in the opposite direction, and control the output rod of the electric push rod 10 to move upward, thereby driving the cutting machine swing frame 2 to swing upward.

[0046] Furthermore, a cutting protective cover 3 is fitted over the cutting saw blade 4, and the side of the cutting protective cover 3 is fixedly connected to the end of the cutting machine swing frame 2, thereby effectively blocking the sparks generated when cutting the steel pipe and protecting the workers.

[0047] The working principle of this utility model is as follows: When in use, first loosen the locking bolts 853 at both ends of the mounting slide plate 851, then adjust the position of the mounting slide plate 851 on the limit slide rod 83 according to the required length of the steel pipe to be cut, and then place the steel pipe into the V-groove at the top of the V-groove seat 81. The V-groove is used to position the steel pipe to prevent it from shifting after the cutting position is subjected to force. Push the steel pipe to move towards the end of the end positioning plate 84. The end of the steel pipe is fitted onto the conical surface of the conical positioning tip 94. The end of the steel pipe is positioned by the conical surface of the conical positioning tip 94. At the same time, when the steel pipe moves, it will push the T-shaped sliding frame 91 to move until the side of the T-shaped sliding frame 91 presses and triggers the limit switch 852, which energizes the electric push rod 10 and drives the end of the cutting machine swing frame 2 to swing downward. The cutting machine drive motor 6 at the end of the cutting machine swing frame 2 will drive the cutting saw blade 4 to rotate at high speed. As the cutting saw blade 4 contacts the steel pipe, it cuts. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
