Description

TECHNICAL FIELD

[0001] The utility model relates to auxiliary feeding and discharging technical field especially, relates to a kind of auxiliary feeding and discharging mechanism of plasma cutting machine. BACKGROUND

[0002] Plasma cutting machine generates plasma arc by high-frequency high-voltage current between electrode and workpiece, melts metal by its heat and forms cut by high-speed airflow. It is composed of power supply, cutting torch, gas supply and control system, and is widely used in metal processing, construction, shipbuilding and other industries. It is necessary for plasma cutting machine to use auxiliary feeding and discharging mechanism. Since metal materials are often heavy, like thick steel plate, which can reach several hundred kilograms, manual handling is laborious and unsafe, while auxiliary mechanism can easily cope with it. It can also improve cutting efficiency. Manual feeding and discharging is slow, and auxiliary mechanism can quickly place and take out materials, reducing equipment standby time and ensuring continuous cutting. In addition, it can accurately position materials, ensuring accurate starting position and direction of cutting, which is crucial for metal processing with high dimensional accuracy and can effectively improve processing quality and efficiency.

[0003] The auxiliary feeding and discharging mechanism of plasma cutting machine is composed of most parts. The conveying device has an electric sliding rail installed on the side wall of the cutting machine, which drives the clamping plate to convey raw materials. There is also a conveyor belt with simple structure that can continuously feed but has slightly lower positioning accuracy. The clamping device includes clamping plates, auxiliary clamping plates and universal wheels, which can effectively clamp and fix raw materials and ensure smooth movement. The positioning device has limit plates and contact plates with rubber plates for accurate positioning and protection of raw materials. The lifting device uses a hydraulic lifting system for large equipment and an electric push rod for small mechanisms. The controller of the control device coordinates all parts, and the sensor ensures accurate operation.

[0004] The existing auxiliary feeding and discharging mechanism placed on the tray has many drawbacks. Materials are easily placed in disorder, the work area is messy, there is a high risk of tripping, and management and searching are difficult. Placing on the ground can easily scratch and stain the materials, such as stainless steel plates, which require high surface quality and may even be scrapped. When feeding, materials need to be carried from the messy area, which is time-consuming and labor-intensive, and it is difficult to place materials in batches and order. The feeding efficiency is low, and the positioning relies on manual operation, which may deviate and is not conducive to precision machining. When cutting, there is no stable support, and the material may shift due to weight distribution and contact surface problems, which affects cutting quality and product consistency. Moreover, the height cannot be adjusted according to the amount of material, which may exceed the range and cause injury, and the amount of material is small, which makes feeding difficult and the distance between the cutting head and the material unsuitable, ultimately affecting production efficiency and processing quality. Therefore, an auxiliary feeding and discharging mechanism for plasma cutting machine is proposed to solve the above problems. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] Referring to Figure 1 and Figure 2 An embodiment provided by the utility model: an auxiliary feeding and discharging mechanism of a plasma cutting machine, comprising a pillar 1, the pillar 1 can be made of high-strength aluminum alloy material, the aluminum alloy has the characteristics of lighter quality, corrosion resistance and higher strength, can reduce the weight of the overall equipment while ensuring the structural stability, is convenient for moving and installing, the top of the pillar 1 is fixedly connected with a first motor 3, the output end of the first motor 3 is fixedly connected with a threaded rod 4, the threaded rod 4 can adopt high-quality alloy steel material, has good wear resistance and strength, can bear larger torque, ensures that it is not easy to deform or damage in the frequent rotating process, the fourth connecting plate 24 is rotatably connected with the outer wall of the threaded rod 4, and the side wall of the pillar 1 is provided with a discharging assembly;

[0033] The discharging assembly comprises a carrier frame 5, which is arranged on the outer wall of the support column 1. The carrier frame 5 can be made of stainless steel, which has strong corrosion resistance and can effectively prevent various stains and moisture generated during the placement of metal materials from corroding the carrier frame 5, thereby prolonging the service life of the carrier frame 5 and facilitating cleaning and maintenance. The side wall of the carrier frame 5 is fixedly connected with a second motor 6, the output end of the second motor 6 is fixedly connected with a fixed column 7, the outer wall of the fixed column 7 is rotatably connected with a first connecting plate 8, the bottom of the first connecting plate 8 is fixedly connected to the inner wall of the carrier frame 5, the outer wall of the fixed column 7 is rotatably connected with a first rotating plate 9, the side wall of the first rotating plate 9 is rotatably connected with a second rotating plate 10, the side wall of the second rotating plate 10 is rotatably connected with a connecting block 11, the side wall of the fourth connecting plate 24 is provided with a moving assembly, the top of the connecting block 11 is fixedly connected with a second supporting plate 26, and the outer wall of the second supporting plate 26 is slidably connected to the inner wall of the carrier frame 5. The side wall of the other support column 1 is provided with a cutting device 2, which is used for cutting materials;

[0034] Specifically, in the process of using the auxiliary feeding and discharging mechanism, first, start the first motor 3, and the output end starts to rotate at high speed, thereby driving the threaded rod 4 connected therewith to stably rotate. Since the threaded rod 4 cooperates with the fourth connecting plate 24 through a specific threaded structure, when the threaded rod 4 rotates, the fourth connecting plate 24 will accurately move along the axial direction of the threaded rod 4, which ingeniously realizes the flexible movement of the feeding position and can adjust the feeding position to the most appropriate place according to the actual feeding demand. Next, turn on the second motor 6, and the output end generates powerful power and drives the fixed column 7 to rotate at a constant speed. There is a stable connection relationship between the fixed column 7 and the first rotating plate 9, and when the fixed column 7 rotates, the first rotating plate 9 will be forced to start rotating. The connecting block 11 and the first rotating plate 9 are rigidly connected, and the first rotating plate 9 rotates to drive the connecting block 11 to stably rotate. The top of the connecting block 11 is closely connected with the second supporting plate 26, so that the rotation of the connecting block 11 can drive the second supporting plate 26 at the top to move up and down in the carrier frame 5. In this way, the ideal effect of automatically and accurately adjusting the height according to the number of material plates is successfully achieved, thereby better adapting to different feeding operation requirements and improving the practicality and flexibility of the entire auxiliary feeding and discharging mechanism.

[0035] Referring to Figure 1 and Figure 3The bottom of the L-shaped connecting plate 17 is fixedly connected with a hollow frame 18, which can be made of high-strength carbon steel, has good structural strength and stability, and can provide reliable support for the internal components. The hollow frame 18 is fixedly connected with a hydraulic cylinder 19 inside. The hydraulic cylinder 19 should be made of high-quality metal sealing parts and high-strength cylinder materials, such as specially treated alloy steel, to ensure stable operation and long service life under high-pressure working conditions. The output end of the hydraulic cylinder 19 is fixedly connected with a third connecting plate 20, which can be made of solid aluminum alloy to reduce weight while ensuring a certain strength. The bottom of the hollow frame 18 is fixedly connected with a second sliding rail 21, which can be made of wear-resistant quenched steel, has good hardness and smoothness, and can effectively reduce the friction when the second sliding block 22 slides and maintain the accuracy of movement. The second sliding rail 21 is slidably connected to the second sliding block 22. The bottom of the third connecting plate 20 is fixedly connected with a first support plate 25, which can be made of stainless steel to prevent damage caused by contact with various environmental factors during long-term use. The top of the first support plate 25 is fixedly connected to the bottom of the second sliding block 22. The bottom of the first support plate 25 is fixedly connected with a clamping column 23, which has a groove in its outer shape. The clamping column 23 can be made of a structure of rubber-coated metal core. The rubber material has good flexibility and friction, which can effectively clamp the material plate to prevent it from falling off without damaging the surface of the material plate.

[0036] Specifically, at the same time, the hydraulic cylinder 19 starts to work, and its output end generates a strong pushing force to push the third connecting plate 20 to move stably in a specific direction. The third connecting plate 20 is rigidly connected with the first support plate 25, so when the third connecting plate 20 moves, the first support plate 25 will be driven to move accordingly. The first support plate 25 is closely connected with the second sliding block 22, so during the movement of the first support plate 25, the second sliding block 22 will smoothly slide on the outer wall of the second sliding rail 21. The second sliding rail 21 provides precise guidance for the sliding of the second sliding block 22, ensuring the accurate direction of the movement of the first support plate 25. With the movement of the first support plate 25, the clamping columns 23 located at the bottom of it will gradually converge under the linkage action of the mechanical structure. These clamping columns 23 cooperate with each other to exert a stable and uniform clamping force on the material plate placed on them, thereby successfully achieving the effect of safely and reliably clamping the material plate, providing a strong guarantee for the subsequent processes such as feeding, transporting and cutting, effectively preventing the material plate from shifting or falling during operation.

[0037] Referring to Figure 1 and Figure 3The moving assembly comprises a third motor 12 fixedly connected at the top of the fourth connecting plate 24, the shell of the third motor 12 can be made of cast aluminum material, which has good heat dissipation performance and can ensure that the motor will not be affected by overheating during long-time operation. The winding inside the third motor 12 should be made of high-quality electromagnetic wire to ensure efficient conversion of electrical energy into mechanical energy. The output end of the third motor 12 is fixedly connected with a connecting shaft 13, which can be made of high-strength alloy steel material and has excellent torsional strength and wear resistance, so as to stably transmit the power of the motor. The side wall of the fourth connecting plate 24 is fixedly connected with a first sliding rail 14 made of wear-resistant quenched steel material as described above. The outer wall of the first sliding rail 14 is slidingly connected with a first sliding block 15 made of copper alloy material with good self-lubricating property, which can reduce frictional resistance and wear during cooperation with the first sliding rail 14, so as to ensure smoothness and precision of movement. The side wall of the first sliding block 15 is fixedly connected with an L-shaped connecting plate 17, the side wall of the L-shaped connecting plate 17 is fixedly connected with a second connecting plate 16 rotatably connected to the outer wall of the connecting shaft 13, and the second connecting plate 16 can be made of aluminum alloy material to reduce the overall weight while ensuring a certain structural strength, which is beneficial to improve the response speed and operating efficiency of the moving assembly.

[0038] Specifically, the third motor 12 starts to work, and the output end generates strong power and transmits it to the connecting shaft 13 to drive the connecting shaft 13 to rotate quickly. The connecting shaft 13 and the second connecting plate 16 are closely connected in transmission, and with the rotation of the connecting shaft 13, the second connecting plate 16 will start to move under the driving of the connecting shaft 13. The L-shaped connecting plate 17 on the side wall of the second connecting plate 16 will also be driven to move accordingly. During the movement of the L-shaped connecting plate 17, the first sliding block 15 connected to the side wall of the L-shaped connecting plate 17 will slide on the outer wall of the first sliding rail 14. The first sliding rail 14 provides a stable and accurate guide path for the sliding of the first sliding block 15, so that the L-shaped connecting plate 17 can keep stable and accurate posture change during movement, thereby successfully realizing accurate control of the height position of the L-shaped connecting plate 17. This control effect plays a key role in accurate positioning and stable transmission of materials in the subsequent feeding operation, and can effectively improve the accuracy and efficiency of the whole auxiliary feeding and discharging process.

[0039] Working principle: when using the auxiliary unloading mechanism, first, the first motor 3 output end drives the threaded rod 4 to rotate, the threaded rod 4 drives the fourth connecting plate 24 to move, achieves the effect of moving the loading position, next, the second motor 6 output end drives the fixed column 7 to rotate, the fixed column 7 drives the first rotating plate 9 to rotate, the first rotating plate 9 drives the connecting block 11 to rotate, the connecting block 11 drives the second support plate 26 at the top to move in the inside of the loading frame 5, achieves the effect of adjusting the height according to the number of material plates, then, the third motor 12 output end drives the connecting shaft 13 to rotate, the connecting shaft 13 drives the second connecting plate 16 to move the L-shaped connecting plate 17 of the side wall, the L-shaped connecting plate 17 drives the first sliding block 15 of the side wall to slide on the outer wall of the first sliding rail 14, achieves the effect of controlling the height of the L-shaped connecting plate 17, at the same time, the hydraulic cylinder 19 output end drives the third connecting plate 20 to move, the third connecting plate 20 drives the first support plate 25 to move, and the movement of the first support plate 25 drives the second sliding block 22 to slide on the outer wall of the second sliding rail 21, then drives the clamping column 23 at the bottom of the first support plate 25 to gather, achieves the effect of clamping the material plate.
