Description

Technical Field

[0001] This utility model relates to the field of round bar cutting technology, specifically to an automatic cutting device for stainless steel round bars. Background Technology

[0002] Currently, in the field of stainless steel round bar cutting, manual feeding combined with sawing is commonly used, or semi-automatic chain conveyor and mechanical limiting device are used in conjunction with cutting equipment. In traditional structures, a fixed-gap transmission roller conveying mechanism and rigid limiting device are mostly used to achieve axial positioning and cutting of the round bar.

[0003] For example, a common stainless steel bar cutting device includes: a frame, a chain-plate feeding mechanism, a limit plate, a hydraulic saw, and a simple control system. After the round bar is conveyed to the cutting position by the chain plate, it is coarsely positioned by the limit block, and the saw blade cuts vertically downwards to complete the cutting. While this type of equipment has achieved basic automation of cutting, it still has the following shortcomings: Unstable conveying process: Since the conveying mechanism is mostly a rigid chain plate or ordinary metal roller, the friction is limited. Especially when processing smooth and rigid bars such as stainless steel, slippage or deviation is likely to occur, affecting the feeding accuracy and the cutting position accuracy.

[0004] Poor clamping adaptability: Most existing clamping and limiting structures are rigid jaws or fixed slots, which cannot be automatically adjusted for bars with different diameters or tolerance ranges. Frequent manual adjustment or replacement of clamps is required, which is inefficient and not conducive to continuous processing.

[0005] In summary, existing stainless steel round bar cutting equipment has significant shortcomings in terms of conveying stability, clamping adaptability, and intelligent linkage control. There is an urgent need for an improved automatic cutting device that can adapt to materials of different specifications and has flexible clamping, stable conveying, and automatic detection functions to improve processing accuracy, efficiency, and operational safety. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: an automatic cutting device for stainless steel round bars, comprising: a conveying base, a sawing machine, and a limiting conveying assembly. Multiple sets of conveying rollers are controlled by a drive motor to achieve stable material conveying. The limiting conveying assembly can flexibly adapt and clamp round bars of different diameters. The sawing machine completes automatic cutting under the action of a lifting drive assembly, and a detection and control linkage is formed with sensors to ensure safe and efficient automated operation. The conveying base is equipped with several conveying rollers arranged along the conveying direction, and each conveying roller is driven to rotate by a drive motor located at the bottom of the conveying base. The drive motor is a geared motor structure, with transmission boxes on both sides for establishing a transmission connection with one or more conveying rollers.

[0008] Specifically, this structure enables stable and continuous conveying of stainless steel round bars, preventing material slippage or deviation, and improving conveying accuracy and transmission reliability.

[0009] In a preferred example, the surface of the conveying rollers is covered with an anti-slip rubber sleeve to increase the friction with the surface of the round bar and effectively prevent conveying instability caused by the smoothness of the material.

[0010] Specifically, the anti-slip rubber sleeve structure enhances the conveying system's ability to support and control the round bar, thereby improving conveying stability and material adaptability.

[0011] In a preferred embodiment, the limiting conveying assembly includes clamping plates symmetrically arranged on both sides of the conveying base. The clamping plates have a plurality of spherical covers along their length, and each spherical cover contains a spiral arc-shaped abutment ball. The abutment ball is a rubber component that can rotate within the spherical cover to accommodate stainless steel rods of different diameters.

[0012] Specifically, the structure improves the adaptability to materials of different sizes through flexible clamping, avoiding jamming and insufficient clamping caused by rigid limiting, and ensuring stable positioning of materials before cutting.

[0013] In a preferred example, the clamping plate is connected to the conveying base via a flexible connecting rod, which has an arc-shaped structure and serves to limit and guide the clamping plate, while also forming auxiliary support with the conveying system.

[0014] Specifically, the flexible connecting rod forms an elastic support, enabling the clamping plate to provide stable limiting and clamping functions under different usage conditions, while facilitating assembly, disassembly and maintenance, and improving structural flexibility.

[0015] In a preferred embodiment, the sawing machine is mounted on a gantry frame on one side of the conveyor base and connected via a lifting drive assembly. The sawing machine includes a drive motor and a saw blade, with the output end of the drive motor connected to the saw blade, and a protective cover provided around the saw blade.

[0016] Specifically, this structure allows the sawing mechanism to move precisely vertically, and together with the clamped and positioned stainless steel rod, it enables high-precision vertical cutting, improving cutting quality and safety.

[0017] In a preferred embodiment, a material sensor is provided on the inner side of the clamping plate to detect whether the round bar has reached the cutting position. The output terminal of the sensor is electrically connected to the drive motor, the lifting drive assembly, and the power control terminal of the sawing machine to form a control linkage relationship.

[0018] Specifically, by setting up sensors to form a closed-loop detection mechanism, real-time monitoring of material conveying status and multi-component linkage control can be achieved, significantly improving the level of automation and operational safety.

[0019] In summary, this utility model, through its rationally designed conveying structure, flexible limiting clamping mechanism, and intelligent control system, achieves fully automated control of the entire process of stainless steel round bars from conveying and positioning to cutting. It has advantages such as reasonable structure, strong adaptability, high precision, and good safety, and is suitable for mass processing of high-hardness round bars such as stainless steel.

[0020] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting up multiple sets of conveying rollers driven by a drive motor and cooperating with the surface anti-slip rubber sleeve design, stable conveying of stainless steel round bars is achieved, avoiding the problems of material slippage and deviation, and improving the reliability and consistency of conveying.

[0021] 2. In this utility model, by setting a limiting conveying component with flexible limiting function, especially the matching structure of the ball and the ball cover, it can automatically adapt to stainless steel round bars of different diameters, ensuring stable clamping of materials during the cutting process, effectively improving sawing accuracy and safety, reducing the frequency of manual adjustment, and improving the level of automation and processing efficiency.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of an automatic stainless steel round bar cutting device provided by this utility model.

[0027] Combination Figures 1-5 As shown, the present invention provides an automatic cutting device for stainless steel round bars, including a conveying base 100, a sawing machine 200, and a limiting conveying assembly 300.

[0028] The conveying base 100 is a long strip structure, with several conveying rollers 130 arranged on its upper surface along the conveying direction to support and convey stainless steel round bars. The conveying rollers 130 are mounted on the conveying base 100 with bearings and are arranged in a straight, uniform manner along their length to achieve stable conveying of the round bar material. To improve conveying stability, each conveying roller 130 is fitted with an anti-slip rubber sleeve, which effectively increases the friction between the roller and the stainless steel round bar, preventing slippage or deviation of the material during conveying.

[0029] A drive motor 110 is fixedly mounted on the bottom surface of the conveying base 100 to provide conveying power. In this embodiment, the drive motor 110 is a geared motor, and the output end of the motor is connected to multiple conveying rollers 130 through a transmission device to drive them to rotate synchronously, thereby realizing the movement of the round bar along the conveying path. The transmission device can be a chain drive or a synchronous belt drive structure, which has high transmission stability.

[0030] A gantry frame 120 is vertically fixed to one side of the conveyor base 100, and a sawing machine 200 is mounted on the upper part of the gantry frame 120. The sawing machine 200 includes a motor body and a saw blade installed at its output end. A protective cover is provided around the saw blade outside the motor body to improve operational safety. The sawing machine 200 is connected to the gantry frame 120 through a lifting drive assembly 210, which is used to control the vertical movement of the sawing machine 200. Preferably, the lifting drive assembly 210 is a screw lifting mechanism or an electric cylinder structure, which can realize the precise lifting of the sawing machine 200 for vertical cutting of the round bar.

[0031] The limiting conveying assembly 300 is disposed on both sides of the conveying base 100, including a clamping plate 310, a flexible connecting rod 320, and a stop ball 330. The clamping plate 310 is a strip-shaped metal component, symmetrically installed on both sides of the conveying base 100. Several ball covers 311 are provided on the upper surface of the clamping plate 310, arranged equidistantly in a straight line along the length of the clamping plate. The stop ball 330 has a spiral arc-shaped structure, is made of rubber, and has spiral ribs on its outer surface to enhance the frictional performance with the stainless steel round bar. The stop ball 330 is rotatably fitted inside the ball cover 311, flexibly clamping the material and adapting to stainless steel round bars of different diameters.

[0032] The flexible connecting rod 320 is an arc-shaped rod, with its two ends fixedly connected to the clamping plate 310 and the conveying base 100, respectively, forming a limiting and guiding mechanism. This mechanism enables the clamping plate 310 to form a wrapping limiting and clamping structure during the conveying of the stainless steel round bar, enhancing the stability of the conveying process. Through the above structural design, the round bar can always be in contact with the surface of the conveying roller 130, avoiding swaying, lateral displacement, and other phenomena that affect the sawing accuracy.

[0033] To achieve automatic control, a material sensor is installed on the inner side of the clamping plate 310. This sensor is used to detect whether the stainless steel round bar has been conveyed to the correct position. When the material sensor detects that the round bar has reached the designated position, its output signal will control the drive motor 110 to stop conveying, and simultaneously trigger the lifting drive assembly 210 to start, driving the sawing machine 200 to move downwards and start the cutting operation. After the cutting is completed, the sawing machine 200 rises to reset, and the drive motor 110 starts again to convey the next section of material, thus completing the fully automatic continuous cutting operation of the stainless steel round bar.

[0034] Working principle and usage process of this utility model: This utility model is based on three core functional modules: "conveying + limiting clamping + sawing". It automatically completes the conveying, positioning, clamping and cutting of stainless steel round bars. The core working principle is as follows: The drive motor 110 drives multiple conveying rollers 130 arranged on the conveying base 100 to rotate, realizing the smooth conveying of round bar materials. The anti-slip rubber sleeves on the surface of the conveying rollers increase friction and prevent the materials from slipping.

[0035] The limiting conveying assembly 300 is connected to the conveying base 100 via a flexible connecting rod 320, realizing the limiting and guiding function of the clamping plate 310. The clamping plate is provided with several ball covers 311, and the ball abutment 330 can rotate flexibly within the ball covers to adapt to stainless steel round bars of different diameters, forming a flexible clamping effect to ensure that the material is in full contact with the surface of the conveying roller 130 and to ensure stability during the sawing process.

[0036] The sawing machine 200, mounted on the gantry frame 120, can move up and down under the action of the lifting drive assembly 210 to achieve vertical cutting of stainless steel round bars in a clamped state. The sawing machine includes a saw blade and a protective cover to ensure cutting efficiency and operational safety.

[0037] A material sensor is installed inside the limiting clamp 310 to detect the position of the stainless steel round bar in real time. When the sensor detects that the material has arrived, it outputs a signal to control the drive motor 110 to stop conveying, the saw 200 to start cutting, and the lifting drive assembly 210 to accurately position and complete the automatic cutting.
