Description

Technical Field

[0001] This utility model relates to the field of straight pipe cutting technology, and in particular to a straight pipe cutting device. Background Technology

[0002] Straight pipes, as a common type of pipe, are widely used in many fields such as construction engineering, machinery manufacturing, metal structures, and home assembly. In actual processing, straight pipes usually need to be cut to a predetermined length to meet the assembly requirements of different products or structures. In order to improve processing efficiency and consistency, a variety of pipe cutting equipment has emerged on the market, and these devices have played an important role in industrial production.

[0003] Existing straight pipe cutting equipment has a relatively simple structure and insufficient stability. The straight pipe is prone to shaking or deviation, and the cutting path is prone to skew. The large amount of metal chips and dust generated during the cutting process often lacks effective collection methods, causing the chips to easily splash around the equipment and even the operating area under the action of high-speed rotating blades, polluting the working environment and reducing the life of the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a straight pipe cutting device with a stable cutting path, which prevents debris from splashing and can effectively collect the debris generated during the cutting process, ensuring a clean working environment.

[0005] To solve the above problems, this utility model provides a straight pipe cutting device, including a machine base, a feeding mechanism disposed on the machine base, and a cutting mechanism disposed on one side of the feeding mechanism. The feeding mechanism is used to carry and transport the straight pipe, and the feeding mechanism transports the straight pipe to a clamping mechanism disposed at the end of the feeding mechanism. The cutting mechanism includes a cutting guide rail, a cutting slide slidably disposed on the cutting guide rail, and a cutting element mounted on the cutting slide. The cutting element includes a cutting blade, and a chip suction cover is provided on one side of the cutting element. The clamping mechanism is provided with a cutting groove that can accommodate the cutting blade and a clamping groove that accommodates the straight pipe and clamps the straight pipe. The clamping groove is located below the cutting groove and is set at an angle to the cutting groove.

[0006] By adopting the above technical solution, during the movement of the cutting element along the cutting guide rail, the cutting blade passes through the cutting groove between the clamping components to complete the cutting operation, which can effectively ensure the stability of the cutting path and improve the cutting accuracy. At the same time, the debris generated during the cutting process will remain in the cutting groove, and the chip suction hood can collect the debris simultaneously, effectively preventing debris from splashing and improving safety.

[0007] A further feature of this invention is that the clamping mechanism includes a support base disposed on the machine base, and a first clamping member and a second clamping member fixedly installed on the support base. The first clamping member and the second clamping member are disposed opposite to each other, and the two form the cutting groove. The cutting blade passes through the cutting groove during its movement along the cutting guide rail, and comes into contact with the straight pipe clamped in the groove during its movement, thereby achieving radial cutting of the straight pipe.

[0008] By adopting the above technical solution, the cutting blade passes through the cutting groove and contacts the straight pipe held in the groove as it moves along the cutting guide, thereby achieving radial cutting of the straight pipe. The cut is flat, the cutting path is clear, and the cutting stability is improved.

[0009] The present invention is further configured such that: the first clamping member includes a first upper clamping block and a first lower clamping block forming a first clamping space; the second clamping member includes a second upper clamping block and a second lower clamping block forming a second clamping space; the projection planes of the first clamping space and the second clamping space along the axial direction of the straight pipe overlap to form the clamping groove.

[0010] By adopting the above technical solution, a multi-point clamping structure can be formed. The first clamping component and the second clamping component tightly clamp the two sides of the cutting groove, making the straight pipe more uniformly stressed, further improving clamping stability, avoiding displacement of the straight pipe during the cutting process, and improving cutting quality.

[0011] A further feature of this invention is that the lower sides of the first upper clamping block and the second upper clamping block, as well as the upper sides of the first lower clamping block and the second lower clamping block, all have V-shaped grooves for limiting the straight tube.

[0012] By adopting the above technical solution, the straight tube can be automatically centered and positioned in the clamping state, avoiding clamping eccentricity, improving clamping accuracy and cutting consistency. At the same time, the V-groove can also partially limit the straight tube, enhance clamping contact stability, and prevent loosening or slippage caused by cutting vibration.

[0013] A further feature of this invention is that: a movable plate is provided inside the support base, the first upper clamping block and the second upper clamping block are connected to the movable plate, and a lifting module is provided inside the machine base, the lifting module driving the movable plate to move up and down in the vertical direction.

[0014] By adopting the above technical solution, the first upper clamping block and the second upper clamping block are installed on the liftable movable plate, and the movable plate is driven to move up and down by the lifting module, which can stably clamp straight pipes of different specifications and realize automatic positioning and clamping.

[0015] A further feature of this invention is that the feeding mechanism includes a feeding bracket, a feeding guide rail disposed on one side of the feeding bracket, a feeding slide table slidably disposed on the feeding guide rail, and a slider fixed on the feeding slide table. The feeding bracket is provided with a groove for placing a straight tube. The slider moves along the groove under the drive of the feeding slide table to push the straight tube to be conveyed toward the clamping mechanism along the direction of the groove.

[0016] By adopting the above technical solution, the feeding mechanism supports the straight tube through the cooperation of the slide and the slider, and is equipped with a feeding guide rail and a feeding slide structure to drive the straight tube to move accurately along a fixed path, smoothly guide the straight tube to the clamping position, realize automated feeding operation, improve feeding efficiency, reduce manual intervention, and facilitate batch continuous processing.

[0017] A further feature of this invention is that the cutting element includes a drive motor and a cutting cover mounted on the cutting slide, the cutting blade is mounted inside the cutting cover, the drive motor drives the cutting blade to rotate, and the chip suction cover has a slot, with the cutting cover engaging with the slot.

[0018] By adopting the above technical solution, the cutting cover absorbs the debris generated in the cutting groove. The chip suction cover is connected to the cutting cover through a slot, which ensures structural stability, improves chip collection efficiency, and ensures a clean working environment.

[0019] A further feature of this invention is that: a housing is provided on the machine base, the cutting mechanism and the clamping mechanism are disposed within the housing, a chip outlet is provided on the housing, the chip suction hood is connected to the chip outlet through a pipe, and the chip outlet is connected to an external suction assembly.

[0020] By adopting the above technical solution, the housing set on the machine base encloses the entire cutting mechanism, forming a closed cutting cavity, which effectively isolates cutting chips and noise; the chip suction hood is connected to the chip outlet of the housing through a pipe, so that the chips generated during cutting can be discharged in a concentrated manner, avoiding accumulation inside that may affect the structural movement or cutting effect. The chip outlet is connected to the external suction component, which can discharge the chips generated during the cutting process to the external collection device in a timely manner, further improving the equipment's cleaning ability.

[0021] A further feature of this invention is that a discharge bracket is provided inside the housing, which is used to receive the cut straight pipe.

[0022] By adopting the above technical solution, a discharge bracket is set inside the shell to receive the cut straight pipe, thus preventing the straight pipe from falling freely after cutting and causing damage or scratches.

[0023] A further feature of this invention is that: a cover is provided on the housing, the upper end of the cover is connected to the housing by a hinge, and an opening sensor is provided on the machine base to detect whether the cover is open.

[0024] By adopting the above technical solution, an openable cover is provided on the shell and connected to the shell through a hinged structure, which makes it convenient for maintenance personnel to open the shell for inspection, tool replacement or cleaning operations; the cover is equipped with an opening sensor, which can promptly issue an alarm or stop the cutting operation when the cover is accidentally opened during equipment operation, ensuring operational safety.

[0025] The beneficial effects of this utility model are:

[0026] The clamping mechanism clamps and fixes the straight pipes on both sides of the cutting groove, and forms a cutting groove between the clamping components. The cutting blade completes the cutting operation along the cutting groove, avoiding the straight pipe from shaking or deviating, ensuring the stability of the cutting path, and improving the cutting accuracy and consistency.

[0027] The clamping mechanism blocks flying debris, and by setting up a chip suction hood that connects to the chip outlet and suction components, it can effectively collect the debris generated during the cutting process, prevent flying debris from injuring people or polluting the environment, and improve operational safety.

[0028] The clamping component adopts a clamping structure, combined with V-groove limiting, and the movable plate is raised and lowered by the lifting module, so that the clamping height is adjustable to adapt to different sizes of pipes. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] according to Figures 1 to 5 As shown, the present invention provides a straight pipe cutting device, including a machine base 1, a feeding mechanism 2 installed on the machine base 1, a cutting mechanism 3 installed on one side of the feeding mechanism 2, and a clamping mechanism 4 installed between the cutting mechanism 3 and the feeding mechanism 2. The mechanisms cooperate and coordinate to realize the continuous automated operation of straight pipe from conveying, clamping and positioning, cutting and processing to end discharge.

[0038] according to Figure 1 As shown, the feeding mechanism 2 includes a feeding bracket 21 and a feeding guide rail 22. A feeding slide 23 is slidably arranged on the feeding guide rail 22, and a slider 25 is fixedly connected to the feeding slide 23. The slider 25 is slidably arranged in a groove 24 on the feeding bracket 21. The groove 24 forms a channel for placing the straight tube and can stably limit the straight tube. Under the action of an external driving mechanism, the feeding slide 23 can drive the straight tube to slide along the groove 24 through the slider 25 and push it to the cutting station, ensuring that the straight tube is always conveyed along the same path and avoiding deviation that causes cutting errors.

[0039] The clamping mechanism 4 is located between the end of the feeding mechanism 2 and the cutting mechanism 3. Its main function is to clamp and position the straight pipe that has been delivered to the position, ensuring that the straight pipe remains stable during cutting and preventing shaking and skewing. The clamping mechanism 4 includes a support base 41 set on the machine base 1. The support base 41 has a vertically movable plate 45 inside. The movable plate 45 is fixed with a first upper clamping block 421 and a second upper clamping block 431, which cooperate with the first lower clamping block 422 and the second lower clamping block 432 installed on the support base 41 to form a first clamping component 42 and a second clamping component 45. The first upper clamping block 421 and the first lower clamping block 422 form a first clamping space. The second upper clamping block 431 and the second lower clamping block 432 form a first clamping space. The projection planes of the first clamping space and the second clamping space along the axial direction of the straight pipe overlap. The first clamping space and the second clamping space together form a clamping groove 47 that accommodates the straight pipe and clamps it.

[0040] The machine tool 1 is equipped with a lifting module 46, which is connected to the movable plate 45. The lifting module 46 is pneumatically driven to lift the first upper clamping block 421 and the second upper clamping block 431 in the vertical direction, thereby achieving clamping or releasing action. The lower contact surfaces of the first upper clamping block 421 and the second upper clamping block 431, and the upper contact surfaces of the first lower clamping block 422 and the second lower clamping block 432 are provided with V-shaped grooves that cooperate with the straight pipe, which can effectively prevent the straight pipe from rolling or slipping in the clamping state and improve cutting stability.

[0041] according to Figure 5 As shown, the cutting mechanism 3 is located on one side of the clamping mechanism 4 and is used to perform transverse cutting on the clamped straight pipe. The cutting mechanism 3 includes a cutting guide rail 31 fixed on the machine base 1. A cutting slide 32 is slidably mounted on the cutting guide rail 31. A cutting element 33 is provided on the cutting slide 32. The cutting element 33 includes a drive motor 332, a cutting blade 331, a cutting cover 333, and a chip suction cover 34. The drive motor 332 is used to drive the cutting blade 331 to rotate at high speed. The cutting blade 331 is located inside the cutting cover 333 to avoid contact with the operator and to prevent flying chips from splashing out. The chip suction cover 34 is located on one side of the cutting element 33 and is inserted into the cutting cover 333 through a slot 334. It can effectively collect the chips and dust generated during the cutting process.

[0042] according to Figure 6 As shown, a cutting groove 44 is formed between the first clamping member 42 and the second clamping member 43 of the clamping mechanism 4 to accommodate the cutting blade 331 passing through, preventing the cutting blade 331 from contacting the clamping member body, while ensuring that the straight pipe can be completely cut off. The cutting slide 32 moves laterally along the cutting guide rail 31 under the drive of the external drive mechanism, driving the blade to move laterally to complete the cutting process, ensuring a stable cutting trajectory, and ensuring that the cutting end face is flat, with few burrs and high precision.

[0043] according to Figure 4 As shown, the cutting mechanism 3 is set in a closed space covered by the housing 5. The housing 5 is provided with a chip outlet 51 for chip removal. The chip suction hood 34 is connected to the chip outlet 51 through a connecting pipe. The chip outlet 51 is also connected to an external suction component, such as a negative pressure fan or a dust collector, which can promptly remove cutting chips from the equipment, reduce dust accumulation, and keep the inside clean. At the same time, the housing 5 is also provided with a discharge bracket 6, which is used to receive and support the cut pipe section to prevent it from falling, colliding, or damaging the surface of the workpiece.

[0044] according to Figure 4 As shown, the housing 5 is provided with an openable cover 52. The cover 52 is connected to the top of the housing 5 by a hinge, forming an upward-opening structure. An opening sensor 7 is installed inside the machine base 1 to detect whether the cover 52 is open. When the cover 52 is detected to be open, the control system can drive the motor 332 to stop rotating and the cutting slide 32 to stop running, preventing the operator from accidentally touching it and causing injury during maintenance or cleaning.

[0045] In operation, the straight tube to be processed is first placed in the groove 24 on the feeding mechanism 2. The feeding slide 23 slides forward under the guidance of the feeding guide rail 22, and the straight tube is pushed to the cutting position of the clamping mechanism 4 by the slider 25. At this time, the lifting module 46 set in the machine base 1 is activated, driving the movable plate 45 connected to the first upper clamping block 421 and the second upper clamping block 431 to move downward, so that the straight tube is clamped with the first lower clamping block 422 and the second lower clamping block 432 below, so that the straight tube is stably fixed on the cutting position. After the positioning and clamping are completed, the cutting mechanism 3 starts to work. The cutting slide 32 slides laterally along the cutting guide rail 31, and at the same time the driving motor 3 The cutting blade 331, located inside the cutting cover 333, is driven to rotate at high speed. Driven by the cutting slide 32, the cutting blade 331 gradually approaches and passes through the cutting groove 44 on the clamping mechanism 4 to cut the clamped straight tube. During the cutting process, the chip suction cover 34 on one side of the cutting blade 331 sucks in the chips in the cutting groove 44 in time and discharges them into the external suction assembly through the chip outlet 51 on the housing 5 via the connecting pipe, thereby avoiding chip splashing and keeping the working environment clean. After the cutting is completed, the lifting module 46 moves in the opposite direction to raise the movable plate 45, release the straight tube, and push the straight tube to the discharge bracket 6 after it is released from the clamping state, thus completing one cutting operation.

[0046] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
