Description

Technical Field

[0001] This utility model relates to construction equipment, and in particular to a high-safety pipe end beveling machine. Background Technology

[0002] In construction and pipeline installation, beveling pipe ends is a common process, and its processing accuracy and operational safety directly affect subsequent assembly quality and construction efficiency. Currently, many pipe beveling machines on the market suffer from unreasonable structural designs: some machines have fixed material rack angles, unable to adapt to different beveling angle processing requirements, necessitating frequent tooling changes or equipment position adjustments, making operation cumbersome and time-consuming; some adjustable-angle machines lack stable pipe positioning and locking mechanisms, making the pipe prone to displacement and shaking during cutting, resulting not only in poor cut smoothness and large angle deviations, but also potential safety hazards.

[0003] Meanwhile, the cutting mechanisms of existing equipment are mostly driven manually or semi-automatically, making it difficult to precisely control the cutting force. This can easily lead to issues such as cutting disc jamming and pipe breakage, affecting processing quality and reducing equipment lifespan. In addition, most equipment lacks a dedicated pipe end support structure, causing the ends of long pipes to sag during cutting, further exacerbating cut deformation. Furthermore, the lack of effective safety protection design increases the risk of accidental contact by operators.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a high-safety pipe end beveling machine, making it more valuable for industrial use. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a high-safety pipe end face beveling machine.

[0006] This utility model discloses a high-safety pipe end beveling machine, which includes a base, a vertically upward-facing stand fixed in the middle of the base, a swing arm movably mounted on the top of the stand via a shaft, a cutting motor mounted on one end of the swing arm, and a cutting blade mounted on the other end of the swing arm via a bearing seat and a shaft. The cutting motor and the cutting blade are connected by a belt and a pulley for transmission. An angle-adjustable material rack is mounted on the base, and the pipe to be cut is placed on the material rack.

[0007] This high-safety pipe end beveling machine includes a base with a vertically upward-facing frame in the middle. A swing arm is movably mounted on the top of the frame via a shaft. One end of the swing arm is equipped with a cutting motor, and the other end is equipped with a cutting blade via a bearing seat and a shaft. The cutting motor and the cutting blade are powered by a belt and pulley to drive the cutting blade. The material rack on the base is adjustable in angle. The pipe to be cut can be placed on the material rack. The movement of the swing arm moves the cutting blade closer to the pipe to complete the cutting operation. The adjustable material rack can adapt to different tilt angle cutting requirements. The overall structure works together to achieve beveling of the pipe end face.

[0008] Furthermore, the material rack includes a material base that is fixedly installed with the base. A rotating plate is movably installed on the bottom end of the material base near the cutting blade via a shaft. The surface of the rotating plate is provided with two sets of pipe supports with slots.

[0009] The material rack consists of a material base fixedly connected to the base. A movable rotating plate is mounted on the bottom end of the material base near the cutting blade via a shaft. The surface of the rotating plate is provided with two sets of pipe supports with slots. The rotating plate can adjust its angle by rotating the shaft to adapt to different cutting needs. The slots of the pipe supports can securely place the pipes to be cut, preventing the pipes from shifting during the cutting process. The material base provides stable support for the entire material rack. All components work together to achieve reliable placement and angle adjustment of the pipes.

[0010] Furthermore, screw holes are provided on the two side walls of the material base. The locking bolts pass through the through hole at the lower end of the support plate and are screwed into the screw holes. The upper end of the support plate has a long, waist-shaped hole. A cross brace is fixed to the bottom of the rotating plate by bolts. There are screws at both ends of the cross brace. The screws pass through the waist-shaped hole of the support plate and are screwed into the locking nuts.

[0011] The material base has screw holes on its two side walls. The locking bolts pass through the through holes at the bottom of the support plate and are screwed into the screw holes to securely install the support plate on the material base. The elongated waist-shaped hole at the top of the support plate provides room for angle adjustment. The bottom of the rotating plate is fixed to the cross brace plate by bolts. The screws at both ends of the cross brace plate pass through the waist-shaped holes and engage with the locking nuts. Tightening the locking nuts fixes the adjustment angle of the rotating plate, while loosening them allows for flexible adjustment of the rotating plate position. Through the cooperation of various components, the angle of the material rack can be accurately fixed and flexibly adjusted.

[0012] Furthermore, a cylinder bracket is fixed to the side wall of the pipe support at the tail end of the rotating plate by bolts. A clamping cylinder is installed at the top of the cylinder bracket. The telescopic rod of the clamping cylinder passes through the cylinder bracket and is fixed to a clamping block. The clamping block works with the pipe support to lock the pipe.

[0013] The pipe support sidewall at the tail end of the rotating plate is fixed to the cylinder support by bolts. The top of the cylinder support is equipped with a clamping cylinder. The telescopic rod of the clamping cylinder passes through the cylinder support and is connected to the clamping block. When the pipe is placed on the pipe support, the clamping cylinder can drive the telescopic rod to move the clamping block downward, which works in conjunction with the pipe support to firmly lock the pipe, preventing the pipe from loosening or shifting during the cutting process, and ensuring the stability and accuracy of the cutting operation.

[0014] Furthermore, an inclined positioning plate is fixed on the base, and a limiting support plate with a waist-shaped groove is installed on the upper end of the positioning plate through an adapter block. A limiting bolt passes through the waist-shaped groove of the limiting support plate, and a nut is screwed into the limiting bolt. The nut cooperates with the limiting bolt to fix the limiting bolt to the limiting support plate. A limiting plate is fixed to the end of the limiting bolt, and the limiting plate is used to support the end of the pipe.

[0015] An inclined positioning plate is fixed on the base. A limiting support plate with a waist-shaped groove is installed on the upper part of the positioning plate through an adapter block. The limiting bolt passes through the waist-shaped groove of the limiting support plate and is screwed into the nut. With the cooperation of the nut and the limiting bolt, the limiting bolt can be fixed to the limiting support plate. The limiting plate at the end of the limiting bolt can provide support for the end of the pipe. The waist-shaped groove design allows the position of the limiting bolt to be adjusted, thereby adapting to pipes of different lengths and ensuring that the end of the pipe will not sag during cutting, further improving cutting stability.

[0016] Furthermore, an adjusting cylinder is movably mounted on the bottom of the upright frame via a shaft, and the top of the adjusting cylinder is movably connected to the tail end of the swing arm via a shaft and a bearing seat.

[0017] An adjusting cylinder is mounted on the bottom of the stand via a shaft. The top of the adjusting cylinder is connected to the tail end of the swing arm via a shaft and bearing seat. The adjusting cylinder can push the swing arm to rotate around the shaft at the top of the stand through its extension and retraction movements, thereby moving the cutting blade closer to or away from the pipe. This allows for flexible control of the start and stop of the cutting operation and the cutting range, making the cutting process more stable and precise.

[0018] By means of the above-described solution, the present invention has at least the following advantages:

[0019] 1. Flexible angle adjustment and strong adaptability: The material rack can be freely adjusted in tilt angle through the cooperation of the rotating plate, the waist-shaped hole of the support plate and the locking nut, which can meet the beveling angle requirements of different specifications of pipes. There is no need to change the tooling or adjust the overall position of the equipment, thus expanding the application range of the equipment.

[0020] 2. Stable pipe positioning and high processing precision: The slot of the pipe support, together with the clamping block driven by the clamping cylinder, can firmly lock the pipe to be cut, avoiding displacement and shaking during the cutting process; at the same time, the limiting plate provides effective support for the end of the pipe, preventing the long pipe from sagging and deforming, and greatly improving the flatness and angle accuracy of the cut.

[0021] 3. Safe and efficient operation with excellent practicality: The cutting mechanism drives the swing arm to operate by adjusting the cylinder, realizing the smooth lifting and lowering of the cutting blade. It replaces the traditional manual or semi-automatic driving method, which not only reduces the labor intensity of operators, but also reduces the risk of cutting blade jamming and pipe breakage. The locking structure of each component is reliably designed, reducing the risk of accidental contact during operation and improving operational safety.

[0022] 4. Reasonable structural design and long service life: The various components of the equipment are firmly connected by bolts, shafts, bearing seats and other structures, which ensures balanced force and smooth operation and reduces component wear; at the same time, the modular structural design facilitates later maintenance and component replacement, extending the overall service life of the equipment and enhancing its industrial application value.

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] See Figure 1 This high-safety pipe end beveling machine operates by placing the pipe to be cut on the material rack 6 on the base 1. The material rack 6 can be flexibly adjusted to adapt to different beveling requirements. Then, the cutting motor 4 at one end of the swing arm 3 is started. The cutting motor 4 transmits power to the cutting blade 5 at the other end of the swing arm 3 through a belt and pulley, causing the cutting blade 5 to rotate at high speed. At the same time, the swing arm 3, supported by a shaft at the top of the stand 2, moves flexibly, driving the cutting blade 5 closer to the pipe to complete the end beveling operation. Throughout the process, all components work together. The adjustable material rack 6 expands the applicability of the equipment. The stable transmission between the cutting motor 4 and the cutting blade 5 ensures cutting efficiency. The flexible movement of the swing arm 3 and the stable support of the stand 2 make the cutting action smoother. The base 1 provides a reliable load-bearing foundation. The overall structure not only achieves precise processing of pipe beveling but also improves the ease of operation and operational stability.

[0031] See Figure 2 The material rack 6 is fixedly connected to the base 1 via the material base 7 to obtain stable support. The rotating plate 8 at the bottom of the material base 7, near the cutting blade 5, can rotate flexibly around the axis to adjust the angle. The pipe to be cut is placed in the slots of the two sets of pipe supports 9 on the surface of the rotating plate 8. The material base 7 provides reliable load-bearing guarantee for the entire material rack 6. The flexible rotation of the rotating plate 8 allows the equipment to adapt to different oblique cutting angle requirements. The slots of the pipe supports 9 can firmly hold the pipe to prevent displacement. The two sets of pipe supports 9 work together to further improve the stability of the pipe placement. The coordinated action of each component not only ensures the firmness of the pipe placement, but also enhances the equipment's adaptability to different cutting requirements.

[0032] See Figure 2 and Figure 3 The locking bolt 10 passes through the through hole at the lower end of the support plate 11 and is screwed into the screw holes on the two side walls of the material base 7, thus achieving a stable connection between the support plate 11 and the material base 7. The bottom of the rotating plate 8 is fixed to the cross brace 12 by bolts. The screws at both ends of the cross brace 12 pass through the waist-shaped hole at the upper end of the support plate 11 and are screwed into the locking nut 13. When adjusting the angle of the rotating plate 8, the locking nut 13 is loosened, and the screw of the cross brace 12 can move along the waist-shaped hole to drive the rotating plate 8 to rotate. After the angle is determined, the locking nut 13 is tightened to fix the position of the rotating plate 8. The stable connection between the material base 7 and the support plate 11 provides a reliable basis for angle adjustment. The cooperation between the waist-shaped hole, the cross brace 12, and the locking nut 13 makes the angle adjustment of the rotating plate 8 flexible and convenient. The double fixing of the locking bolt 10 and the locking nut 13 ensures that it is not easy to loosen after the angle is adjusted. All components work together to achieve precise adjustment and stable locking of the material rack angle, improving the processing adaptability and reliability of the equipment.

[0033] The cylinder bracket 14 is fixed to the side wall of the pipe bracket 9 at the tail end of the rotating plate 8 by bolts, providing a stable installation base for the clamping cylinder 15. The clamping cylinder 15 is installed at the top of the cylinder bracket 14, and its telescopic rod passes through the cylinder bracket 14 and is fixedly connected to the clamping block 16. After the pipe is placed on the pipe bracket 9, the clamping cylinder 15 drives the telescopic rod to extend and retract, causing the clamping block 16 to approach and fit against the pipe. It works in conjunction with the pipe bracket 9 to complete the locking operation of the pipe. The stable installation of the cylinder bracket 14 ensures the operational stability of the clamping cylinder 15. The clamping block 16 driven by the clamping cylinder 15 has a uniform and reliable locking force, which can effectively prevent the pipe from loosening or shifting during the cutting process. In conjunction with the pipe bracket 9, it further improves the accuracy of pipe positioning, reduces processing errors caused by pipe shifting, and enhances the safety and processing quality of the cutting operation.

[0034] The positioning plate 17 is tilted and fixed on the base 1. A limiting support plate 18 with a waist-shaped groove is installed on its upper end through an adapter block. The limiting bolt 19 passes through the waist-shaped groove of the limiting support plate 18 and is screwed into the nut. The limiting bolt 19 is fixed in a suitable position by the cooperation of the nut and the limiting bolt 19. The limiting plate 20 at the end of the limiting bolt 19 fits against the end of the pipe to form a support. The position of the limiting bolt 19 in the waist-shaped groove can be adjusted by loosening the nut according to the length of the pipe, ensuring that the limiting plate 20 can provide effective support for the end of pipes of different lengths. The tilted design of the positioning plate 17 and the limiting support plate 18 provide a stable installation foundation. The waist-shaped groove allows for flexible adjustment of the position of the limiting bolt 19, which can be adapted to pipes of different lengths. The support of the limiting plate 20 for the end of the pipe can prevent the pipe from sagging and deforming during cutting, improve cutting accuracy, enhance the stability of the pipe placement, and reduce operational risks.

[0035] See Figure 1 The adjusting cylinder 21 is movably mounted on the bottom of the upright 2 via a shaft. Its top end is flexibly connected to the tail end of the swing arm 3 via a shaft and bearing seat. During the cutting operation, the adjusting cylinder 21 pushes the swing arm 3 to rotate around the shaft at the top of the upright 2 through its extension and retraction action, thereby causing the cutting blade at the other end of the swing arm 3 to move closer to or away from the pipe, thus completing the start and stop of the cutting action and the control of the cutting amplitude. Its advantage is that the upright 2 provides a stable installation support for the adjusting cylinder 21, and the flexible connection between the adjusting cylinder 21 and the swing arm 3 makes the cutting action more stable and precise, replacing the traditional manual drive method, reducing the labor intensity of the operator, and at the same time, it can accurately control the cutting rhythm, reduce the risk of cutting blade jamming or pipe breakage, and improve work efficiency and safety.
