Description

Technical Field

[0001] This utility model belongs to the technical field of pipe cutting equipment, specifically relating to a building pipe cutting device. Background Technology

[0002] In the construction process, pipe cutting is a common and crucial operation, involving the cutting of various materials and specifications of pipes, including steel, plastic, and aluminum alloy pipes. Currently, existing pipe cutting equipment has several shortcomings:

[0003] Firstly, the pipe fixing effect is unsatisfactory. Traditional cutting devices often employ fixed or limited-adjustment fixing mechanisms, making it difficult to adapt to pipes of different diameters and lengths. During cutting, pipe swaying and shifting are prone to occur, leading to reduced cutting accuracy, affecting construction quality, and potentially causing safety accidents. Especially when cutting long pipes into several short pipes at predetermined distances, the lack of a targeted, synchronized fixing structure on both sides of the cutting blade makes the pipes highly susceptible to tilting under cutting force. This not only damages the flatness of the cut surface but may also cause the pipes to detach from the fixing mechanism, resulting in equipment damage or personal injury.

[0004] Secondly, the cutting efficiency is low. The position adjustment of the cutting mechanism in existing devices mostly relies on manual operation, which is not only time-consuming and labor-intensive, but also lacks sufficient adjustment precision, making it difficult to achieve fast and accurate cutting operations. The efficiency bottleneck is particularly prominent when performing batch cutting operations.

[0005] Third, they are limited in function. Existing cutting devices often only have cutting capabilities and lack auxiliary functions related to the cutting operation, such as cutting depth control. These functions require additional tools, which increases the complexity of the operation process. Utility Model Content

[0006] In view of the problems and deficiencies of the existing technology, the present invention provides a building pipe cutting device that can achieve stable fixing of pipes, adapt to various specifications of pipes, and has auxiliary cutting function.

[0007] This utility model is achieved through the following technical solution:

[0008] A building pipe cutting device includes a body, with a loading platform and a cutting table arranged sequentially above the body along the pipe conveying direction.

[0009] The stage includes a slide box fixed to the body, a support roller slidably connected to the slide box, a support slide block slidably connected to the slide box and located on one side of the support roller, and a drive assembly for driving the support slide block to slide along the extension direction of the slide box. The outer peripheral surface of the support roller is provided with an arc-shaped bearing groove adapted to the outer contour of the tube to bear one end of the non-cut part of the tube. The support slide block has a V-shaped bearing part and a clamping and fixing part. The clamping and fixing part squeezes the tube to the V-shaped bearing part to clamp and fix the other end of the non-cut part of the tube.

[0010] The cutting table includes a fixed clamp, a movable clamp, and a cutting device. The fixed clamp is fixed to the machine body and located at the junction of the worktable and the cutting table. The movable clamp is slidably connected to the machine body via a linear slide rail and is located on the side of the fixed clamp away from the worktable. An adjustable cutting space is formed between the fixed clamp and the movable clamp.

[0011] By setting up support rollers and support slides on the platform, the non-cutting part of the pipe can be fixed from both ends. The arc-shaped bearing groove of the support rollers can be adapted to the outer contour of different pipes, and the support slides can be moved by the drive assembly to adapt to pipes of different lengths. The fixed clamp and movable clamp of the cutting table form an adjustable cutting space, which can fix the cutting part, effectively solve the problem of poor fixing effect of traditional devices, improve cutting accuracy and safety, and adapt to pipes of different specifications.

[0012] Through the collaborative design of the stage and cutting table, a dual fixing system of "non-cutting part + cutting part" is constructed. The arc-shaped bearing groove of the supporting roller adopts a gradual curvature design, which can conform to the curved surface of pipes with different outer diameters. Combined with the V-shaped bearing part of the supporting slide, a three-point positioning structure is formed from both ends, solving the problem of imbalance in the fixing of long pipes by traditional fixing mechanisms. The fixed clamp and movable clamp of the cutting table form an adjustable cutting space through a linear slide rail, which can be flexibly adjusted according to the cutting length. Moreover, the clamping structures on both sides of the cutting space can counteract the radial force generated during cutting, greatly reducing the risk of pipe swaying and significantly improving the flatness of the cut surface. At the same time, the sliding design of the supporting slide makes the device adaptable to pipes of various lengths, with a wide range of applications, and can meet the cutting needs of most pipe specifications in construction.

[0013] Furthermore, both the fixed clamp and the movable clamp are equipped with a V-shaped bearing block and a pressure plate located above the V-shaped bearing block. An adjusting bolt is installed between the pressure plate and the V-shaped bearing block, and the distance between the pressure plate and the V-shaped bearing block can be changed by turning the adjusting bolt.

[0014] The fixed and movable clamps, with their V-shaped bearing blocks and pressure plates, form an adjustable clamping unit. The adjusting bolts feature fine-threaded designs, allowing for precise adjustment of the spacing and accurate adaptation to pipes of varying wall thicknesses and diameters. For thin-walled plastic pipes, reduced clamping force prevents pipe deformation; for thick-walled steel pipes, increased pressure ensures stability, resolving the issues of pipe damage or fixation failure caused by uncontrollable clamping force in traditional fixing devices. Furthermore, the combination of the V-shaped structure and pressure plate creates a self-centering effect, automatically correcting pipe placement deviations, reducing manual alignment difficulty, and improving operational convenience.

[0015] Furthermore, the inner side of the clamp of both the V-shaped bearing section and the V-shaped bearing block is provided with anti-slip texture, which is a strip-shaped protrusion extending perpendicular to the pipe conveying direction.

[0016] The anti-slip texture on the inner side of the V-shaped bearing section and V-shaped bearing block clamp is made of highly elastic rubber. The design of the strip-shaped protrusions extending vertically creates a "lateral locking" effect. When the pipe tends to slide axially under cutting force, the protrusions can embed into the tiny textures on the pipe surface, significantly increasing the static friction coefficient and preventing the pipe from slipping during high-speed cutting. At the same time, the rubber material avoids scratches on the pipe surface caused by direct metal-to-metal contact, protecting the appearance quality of high-precision pipes, and is especially suitable for cutting pipes with high requirements for surface finish.

[0017] Furthermore, the cutting table also includes a first motor that drives the movable clamp to move, and the first motor is connected to the movable clamp via a lead screw;

[0018] The drive assembly includes a second motor, which is connected to the support slide via a lead screw.

[0019] The first motor is connected to the moving clamp via a ball screw, enabling automated adjustment of the cutting space and significantly improving efficiency compared to manual adjustment. The second motor drives the screw transmission structure of the supporting slide, which can be programmed to preset fixed positions for different pipe lengths. This eliminates the need for repeated adjustments during batch cutting, reducing the fixing time for each pipe. The self-locking characteristic of the screw transmission ensures stable positioning during power outages or load changes, preventing fixing failures due to mechanical loosening and improving the reliability of the device.

[0020] Furthermore, the cutting device includes a vertically arranged column, a cutting machine slidably connected to the column, and a third motor that drives the cutting machine to move vertically along the column. The third motor can control the amount of displacement of the cutting machine in the vertical direction.

[0021] The cutting device's column uses a high-precision linear guide, and a third motor drives the cutting machine to achieve high-precision displacement control. Cutting depths can be preset for different pipe materials, avoiding over-cutting that could lead to tool wear or incomplete cutting. This structure replaces the traditional manual handheld ruler positioning method, significantly reducing depth control errors, and supports a one-button reset function, improving operational efficiency during tool or material changes and reducing auxiliary operation time.

[0022] Furthermore, a slide rail is provided above the slide box along its length, and multiple positioning holes are spaced apart on the slide rail. The bottom of the supporting slide roller and the supporting slide block are provided with sliders that cooperate with the slide rail, and the sliders are provided with positioning pins that are adapted to the positioning holes.

[0023] The slide rail of the slide box is made of high-strength steel that has undergone quenching treatment, and combined with the wear-resistant material of the slider, it forms a low-friction sliding pair, ensuring smooth movement of the support roller and support slide. Positioning holes are evenly distributed along the entire length of the slide rail, enabling multi-level positioning of the support roller and support slide to meet the fixing requirements of different spacings. The positioning pin adopts a spring-loaded telescopic structure, which, after being inserted into the positioning hole, is locked with an anti-loosening nut. This effectively solves the positioning drift problem caused by gaps in traditional slide rails due to long-term use, ensuring consistent fixing benchmarks for each pipe during batch cutting and improving cutting consistency.

[0024] Furthermore, the clamping and fixing part includes a second pressure plate and an electric telescopic rod connected to the second pressure plate. The electric telescopic rod is vertically fixed to the top of the support slide. The telescopic end of the electric telescopic rod is connected to the second pressure plate and can drive the second pressure plate to move in the vertical direction to squeeze the pipe located above the V-shaped bearing part.

[0025] The electric telescopic rod of the clamping and fixing part is servo-controlled and can automatically adjust the thrust through current feedback. It automatically reduces the force when pipe deformation is detected to avoid damage. An elastic pad is attached to the bottom of the second pressure plate, which increases friction and cushions clamping impact. Compared to a manual screw clamping structure, the electric control responds quickly and supports remote linkage control, interlocking with the cutting device. Cutting cannot start if the pipe is not clamped, improving operational safety. For pipes with significant diameter differences, there is no need to change the clamps; the telescopic rod stroke adaptively adjusts, reducing tooling change costs and operational complexity.

[0026] Furthermore, a collection box is fixed on one side of the machine body, with an opening at the top of the collection box. A first material discharge ramp is provided between the cutting table and the collection box, with one end of the first material discharge ramp connected to the edge of the cutting table and the other end extending above the opening of the collection box.

[0027] The collection box is made of durable materials, and its top opening size is suitable for collecting most short pipes after cutting. The surface of the first drop ramp is treated with a low-friction coating to ensure smooth and unobstructed pipe flow. The ramp and the edge of the cutting table are connected by a rounded transition to avoid impact damage to the pipes during fall. This structure allows for automatic collection of cut pipes, reducing manual picking time, and the collection box can be easily transported as a whole when full, keeping the work area clean and improving the quality of the working environment.

[0028] Furthermore, a second discharge ramp is installed on the side of the movable clamp away from the fixed clamp. One end of the second discharge ramp is fixed to the movable clamp, and the other end is mounted above the first discharge ramp. The width of the second discharge ramp is smaller than the width of the first discharge ramp.

[0029] The second discharge ramp is made of lightweight, high-strength material and moves synchronously with the movable clamp. Its length is designed to maintain effective overlap with the first discharge ramp at all times. Its narrower width than the first ramp prevents interference between the two and creates a "progressive" material guide channel, solving the problem of material skew caused by a shift in the center of gravity after cutting long pipes. For short pipes of varying lengths, the guiding effect of the double ramps significantly improves discharge accuracy, reduces the probability of material getting stuck in the ramp gaps, and ensures a smooth and efficient collection process.

[0030] Furthermore, the machine body is equipped with a control panel, which is electrically connected to the first motor, the second motor, the third motor and the electric telescopic rod, and the control panel has a built-in PLC controller.

[0031] The control panel features an intuitive touchscreen interface and a built-in PLC controller capable of storing multiple sets of cutting parameters, including pipe material, diameter, length, and cutting depth. Through signal interaction with each motor, the entire process is automated, from pipe fixing and cutting space adjustment to cutting depth control and final reset, requiring no manual intervention. The system has a self-diagnostic function; in case of motor overload or sensor malfunction, it will issue audible and visual alarms and automatically shut down, reducing the risk of equipment damage. For batch cutting, operators only need to load the materials, significantly increasing the workload per shift and improving overall cutting efficiency.

[0032] The beneficial effects of this utility model are:

[0033] 1. Significantly improved fixation: The multiple fixation structures of the stage and cutting table can accommodate pipes of different diameters and lengths, effectively preventing pipe shaking, displacement and detachment during the cutting process, thus improving cutting accuracy and construction safety.

[0034] 2. Significantly improved cutting efficiency: The use of motor drive enables automated adjustment of each component, replacing manual operation. This not only saves manpower but also improves adjustment accuracy and speed, with a clear advantage, especially in batch cutting operations.

[0035] 3. Multifunctional: It integrates auxiliary functions such as cutting depth control and pipe collection, eliminating the need for additional tools, simplifying the operation process, and enhancing the practicality and applicability of the device.

[0036] 4. Easy to operate: The control panel enables automated control, making it convenient to operate, reducing the difficulty of manual operation, and allowing operators to quickly master and use it. Attached Figure Description
