Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding equipment for producing vibrating screens for oil drilling. Background Technology

[0002] Vibrating screens for oil drilling are core components of drilling fluid solids control systems. Their main function is to separate solid impurities such as cuttings and silt from the drilling fluid, ensuring the smooth circulation of drilling fluid and the smooth progress of drilling operations. The vibrating screen must be firmly connected to its frame to withstand the high-frequency vibrations and impact loads during drilling operations. Therefore, the welding quality between the screen and the frame is crucial to ensuring the service life and operational reliability of the vibrating screen. Currently, the industry mostly uses plasma arc welding machines for welding operations. However, the welding equipment often employs a "cut-then-weld" process. The cut screen is prone to displacement during welding, leading to welding deviations. Furthermore, most are single-station designs, requiring alternating welding, cutting, and loading / unloading, resulting in low production efficiency and a lack of immediate post-weld inspection mechanisms, easily overlooking defective products with weak welds. Simultaneously, the welding process lacks effective clamping of the welded area and specific preheating and cooling structures, making it prone to weld cracking due to stress concentration. This makes it difficult to meet the "high efficiency, high quality, stable and reliable" requirements for the large-scale production of vibrating screens for oil drilling.

[0003] To address the above problems, this invention proposes a welding device for producing vibrating screens for oil drilling. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of common plasma arc welding machines, which often employ a "cut-then-weld" process. This process leads to displacement of the cut screen during welding, resulting in welding deviations. Furthermore, these machines are typically single-station designs, requiring alternating welding, cutting, and loading / unloading operations, resulting in low production efficiency and a lack of immediate post-weld inspection mechanisms. Additionally, the welding process lacks effective clamping of the welded area and specific preheating and cooling structures, making the weld prone to cracking due to stress concentration. Therefore, this invention proposes a welding device for producing vibrating screens used in oil drilling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A welding device for producing vibrating screens for oil drilling includes a processing mechanism. The processing mechanism includes a base, and a cutting component, a welding conveying device, and two cutting conveying devices are arranged above the base. The cutting component is located between the two cutting conveying devices. The base is also equipped with a welding mechanism. The welding mechanism includes two adjusting components, and the same linear ball screw structure is provided on the sliding sleeves of the two adjusting components. The welding components are provided on the linear ball screw structure.

[0006] Preferably, the welding conveyor and the two cutting conveyors are connected by two belt drive structures, and the welding conveyor is equipped with a welding roller group.

[0007] Preferably, the welding conveying equipment is provided with multiple clamping structures, and multiple sets of alignment frames are installed on the welding conveying equipment, with each set of alignment frames consisting of four frames.

[0008] Preferably, two limiting frames are fixedly connected to the base, the two limiting frames limit the mesh tray, the mesh tray winds up the screen, and a pressure roller is fixedly connected to one side of the two limiting frames.

[0009] Preferably, the cutting assembly includes a mounting frame, on which two electric push rods are fixedly mounted on both the upper and lower sides, and a cutting blade is fixedly connected to one end of each electric push rod.

[0010] Preferably, the upper cutting blade has a bevel on both sides, through which the cut screen is smoothly bent and pressed against the edge of the frame.

[0011] Preferably, the adjustment assembly includes two mounting plates, which are fixedly connected to the base. An adjustment cylinder is fixedly mounted on one of the mounting plates. A connecting plate is fixedly connected to one end of the adjustment cylinder. A sliding sleeve is fixedly connected above the connecting plate. The sliding sleeve is slidably connected to a sliding rod. Both ends of the sliding rod are fixedly connected to the two mounting plates respectively.

[0012] Preferably, the welding assembly includes a telescopic cylinder, which is mounted on the nut pair of a linear ball screw structure. A motor is fixedly installed at the bottom end of the telescopic cylinder, and the output shaft of the motor is fixedly connected to a top plate. A plasma arc welding machine is mounted on the top plate.

[0013] Preferably, two conveying structures are installed below the top plate, and the conveying structures are equipped with a set of guide rollers. The conveyor belt of the conveying structures is a metal wire mesh belt.

[0014] Preferably, two conveying structures are installed below the top plate, and the conveying structures are equipped with a set of guide rollers. The conveyor belt of the conveying structures is a metal wire mesh belt.

[0015] Compared with the prior art, the present invention provides a welding equipment for producing vibrating screens for oil drilling, which has the following advantages: 1. This welding equipment for producing vibrating screens for oil drilling uses a welding conveyor to transport the screen and frame into the welding zone, where a plasma arc welding machine welds the entire screen and frame together. Because the welding and cutting conveyors have a pre-reserved space, the welded screen passes through, effectively detecting whether the screen and frame are firmly welded. If the weld is weak, the frame falls directly. The firmly welded screen and frame then enter the cutting conveyor for cutting. Throughout the process, the screen and frame are transported as a single unit, effectively preventing displacement and facilitating efficient subsequent cutting. The integrated conveying allows for automatic screen opening, eliminating the need for separate screen placement. Furthermore, the welding process can also complete the cutting of the previous batch, enabling highly efficient processing.

[0016] 2. The welding equipment for producing vibrating screens for oil drilling uses a telescopic cylinder to drive the conveying structure downwards and press it against the screen, ensuring a tight fit between the screen and the frame and preventing incomplete welds. Simultaneously, the plasma arc welding machine is equipped with front and rear flow dividers, allowing the compressor and eddy current heat pipes to achieve hot and cold flow separation. Before welding, the hot airflow preheats the conveyor belt of the transmission roller group and the conveying structure, effectively preheating the welding position, reducing the temperature gradient during welding, and minimizing stress concentration. After welding, the cold airflow simultaneously and rapidly cools the welding position, refining the weld grains, increasing weld strength, and effectively preventing weld cracking.

[0017] 3. This welding equipment for producing vibrating screens for oil drilling, through a welding conveyor and two cutting conveyors, can continuously transport the screen and frame. This multi-station continuous flow provides a stable process environment for precise welding. The screen and frame move smoothly between stations, avoiding damage to the weld surface caused by transfer, ensuring precise connection between welding, inspection, and cutting processes. The clamping and preheating / cooling functions of the welding components provide quality assurance for continuous production. Furthermore, the linear ball screw structure and adjustment components allow for precise adjustment of the welding position. Stable welding quality eliminates the need for frequent machine stops for subsequent cutting and inspection processes, improving the smoothness and efficiency of the overall production process. This integrated production process, encompassing continuous feeding, precise welding, rapid preheating and cooling, real-time inspection, and synchronous cutting, provides equipment support for a reliable supply of vibrating screens for oil drilling.

[0018] 4. The welding equipment for producing vibrating screens for oil drilling can simultaneously cut the screen using two cutting blades, one above and one below. After cutting, the lower cutting blade retracts while the upper cutting blade continues to advance downwards. The beveled surface of the cutting blade can smoothly bend the excess edge of the screen after cutting and press it against the edge of the frame. This allows for automatic edge finishing during cutting, effectively avoiding quality defects such as burrs and warping, and eliminating the need for separate processing. The entire operation is more seamless, improving the processing efficiency of the entire process. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Example 1: Refer to Figures 1-8 A welding device for producing vibrating screens for oil drilling includes a processing mechanism 100. The processing mechanism 100 includes a base 101. Above the base 101 are a cutting assembly 106, a welding conveying device 103, and two cutting conveying devices 102. The cutting assembly 106 includes a mounting frame 1061. Two electric push rods 1063 are fixedly mounted on both the upper and lower sides of the mounting frame 1061. One end of each electric push rod 1063 is fixedly connected to a cutting blade 1062. The upper cutting blade 1062 has inclined surfaces on both sides. The cutting blade 1062... The inclined surface smoothly bends the cut screen and presses it against the edge of the frame. The electric push rod 1063 pushes the cutting blade 1062 to move, so that the two cutting blades 1062 can cut the screen at the same time. After cutting, the lower cutting blade 1062 retracts, while the upper cutting blade 1062 continues to move downward. The inclined surface of the cutting blade 1062 can smoothly bend the remaining edge of the screen after cutting and press it against the edge of the frame. This can automatically retract the edge during cutting, effectively avoiding quality defects such as burrs and curling edges, and no separate processing is required. The whole operation is more seamless and improves the processing efficiency of the entire process. The welding conveyor 103 and the two cutting conveyors 102 are connected by two belt drive structures 104. The belt drive structures 104 enable power transmission, allowing the welding conveyor 103 and the cutting conveyors 102 to move synchronously. The welding conveyor 103 is equipped with a welding roller group 107, which provides stable support to the conveyor belt, ensuring tight pressing of the screen and frame. The welding conveyor 103 is equipped with multiple clamping structures 111, which limit the movement of the frame on both sides, accommodating frame positioning of different sizes. This method ensures frame stability through limiting movement, preventing direct locking from affecting the subsequent conveying of the frame to the cutting conveyor 102. The welding conveyor 103 is equipped with... Multiple alignment frames 105 are provided to position the four corners of the frame, ensuring its stability. Each set of alignment frames 105 consists of four frames. The cutting assembly 106 is located between two cutting conveyors 102. A welding mechanism 200 is also provided on the base 101. Two limiting frames 109 are fixedly connected to the base 101. The limiting frames 109 can support and limit the screen tray 108, allowing the screen tray 108 to move through the notch of the limiting frames 109, ensuring that the screen tray 108 can be smoothly released from the screen and making it easy to disassemble the two limiting frames 109 to limit the screen tray 108. The screen tray 108 can rewind the screen. A pressure roller 110 is fixedly connected to one side of the two limiting frames 109. The pressure roller 110 can press the lowered screen onto the frame, thus facilitating the subsequent welding operation between the screen and the frame through pretreatment. The welding mechanism 200 includes two adjusting components 201, each including two mounting plates 2011 fixedly connected to the base 101. One mounting plate 2011 has an adjusting cylinder 2012 fixedly mounted on it. The adjusting cylinder 2012 moves the connecting plate 2013, causing the sliding sleeve 2015 to move the linear ball screw structure 202, thereby adjusting the left and right positions of the welding assembly 203 to facilitate welding operations by the plasma arc welding machine 2037. One end of the adjusting cylinder 2012 is fixedly connected to the connecting plate 2013, and the sliding sleeve 2015 is fixedly connected above the connecting plate 2013. The sliding sleeve 2015 slides smoothly on the sliding rod 2014, thereby enabling the linear ball screw structure 202 to move smoothly. The sliding sleeve 2015 is slidably connected to the sliding rod 2014. The two ends of the sliding rod 2014 are fixedly connected to the two mounting plates 2011 respectively. The same linear ball screw structure 202 is provided on the sliding sleeve 2015 of the two adjusting components 201. The front and rear positions of the welding component 203 can be adjusted through the linear ball screw structure 202, thereby cooperating with the adjusting component 201 to enable the plasma arc welding machine 2037 to move longitudinally and laterally, which facilitates the welding operation of the screen and frame. The welding component 203 is provided on the linear ball screw structure 202.

[0024] In this embodiment: the welding conveyor 103 can transport the screen and frame into the welding area, so that the plasma arc welding machine 2037 can weld the entire screen and frame into shape. Since the welding conveyor 103 and the cutting conveyor 102 have reserved a space, the welded screen can pass through, which can effectively detect whether the screen and frame are welded firmly. If there is a weak weld, the frame will fall directly. The firmly welded screen and frame enter the cutting conveyor 102 for cutting. In the whole process, the screen and frame are transported in an integrated and orderly manner, which effectively avoids displacement and facilitates subsequent efficient cutting. Moreover, the integrated forming conveyor can automatically pull open the screen without the need for separate screen placement. In addition, the welding process can also complete the cutting of the previous welding batch, thereby completing the efficient processing operation.

[0025] Example 2: Refer to Figures 8-10A welding device for producing vibrating screens for oil drilling includes a welding assembly 203. The welding assembly 203 includes a telescopic cylinder 2031, which adjusts the position of a conveying structure 2035 to ensure smooth pressing of the conveying structure 2035 onto the screen, facilitating a tight fit between the screen and the frame. The telescopic cylinder 2031 is mounted on the nut pair of a linear ball screw structure 202. A motor 2032 is fixedly installed at the bottom of the telescopic cylinder 2031, which can adjust the position of the plasma arc welding machine 2037 and the conveying structure. The orientation of structure 2035 and the diverter head 2039 ensures welding in different directions and guarantees that preheating is performed before welding. The output shaft of motor 2032 is fixedly connected to top plate 2033. Plasma arc welding machine 2037 is installed on top plate 2033. Two conveying structures 2035 are installed below top plate 2033. The conveying structures 2035 are equipped with conductive roller groups 2038. The conductive roller groups 2038 have heat conduction and temperature conduction properties, which facilitates the conduction of cold or hot airflow to the conveying structures 2035. The conductive roller groups 2038 can also regulate the flow of heat. The conveyor belt support of the conveyor structure 2035 ensures that the screen is pressed firmly against the frame, facilitating high-quality welding operations. Furthermore, during the plasma arc welding machine 2037's motion welding, the conveyor structure 2035 can move along the screen, reducing resistance and ensuring smooth welding operations. The conveyor belt of the conveyor structure 2035 is a metal wire mesh belt, which not only allows for direct heat conduction but also facilitates airflow for preheating and cooling the welding area. A compressor is fixedly installed below the top plate 2033. 2034, the compressor 2034 is connected to two vortex heat pipes 2036 at both ends. Air is cut into the vortex heat pipes 2036 through the compressor 2034, so that the vortex heat pipes 2036 can smoothly divide the gas into two streams, cold air and hot air, and then discharge them through the splitter head 2039. This facilitates the preheating of the welding area and the cooling after welding, and effectively prevents the weld seal from cracking. The cold end and hot end of the two vortex heat pipes 2036 are connected to the two splitter heads 2039 respectively. The splitter heads 2039 are located above the conduction roller group 2038.

[0026] In this embodiment: the telescopic cylinder 2031 drives the conveying structure 2035 to press downwards onto the screen, which can tightly press the screen and the frame together to ensure a tight fit between the welding surfaces and avoid incomplete welding. At the same time, the plasma arc welding machine 2037 is equipped with flow dividers 2039 at the front and rear, so that the compressor 2034 and the eddy current heat pipe 2036 can realize the separation of hot and cold flow. Before welding by the plasma arc welding machine 2037, the hot airflow preheats the conveyor belt of the conduction roller group 2038 and the conveying structure 2035, effectively preheating the welding position, reducing the temperature gradient during welding, and reducing stress concentration. After welding, the cold airflow simultaneously and rapidly cools the welding position, which refines the weld grains, improves the welding strength, and effectively avoids the problem of easy cracking of the weld.

[0027] Example 3: Reference Figures 1-4 and Figures 7-8 A welding equipment for producing vibrating screens for oil drilling includes a processing mechanism 100. The processing mechanism 100 includes a base 101. A cutting component 106, a welding conveying device 103, and two cutting conveying devices 102 are arranged above the base 101. The cutting component 106 is located between the two cutting conveying devices 102. A welding mechanism 200 is also arranged on the base 101. The welding mechanism 200 includes two adjusting components 201. The same linear ball screw structure 202 is provided on the sliding sleeve 2015 of the two adjusting components 201, and the welding component 203 is provided on the linear ball screw structure 202.

[0028] In this embodiment: the welding conveyor 103, linked to the belt drive structure 104, can drive the movement of two cutting conveyors 102, thereby continuously conveying the screen and frame. This multi-station continuous flow provides a stable process environment for precise welding. The screen and frame move smoothly between stations, avoiding damage to the welding surface caused by transfer, ensuring precise connection between welding, inspection, and cutting processes. The pressing and preheating / cooling functions of the welding component 203 provide quality assurance for continuous production. Furthermore, the linear ball screw structure 202 and the adjusting component 201 can precisely adjust the welding position. Stable welding quality eliminates the need for frequent machine stops for subsequent cutting and inspection processes, improving the smoothness and efficiency of the overall production process. This integrated production process of continuous feeding, precise welding, rapid preheating and cooling, real-time inspection, and synchronous cutting provides equipment support for the reliable supply of vibrating screens for oil drilling.

[0029] Working principle: During welding operations, the screen and frame are conveyed to the welding area by the welding conveyor 103. Then, the telescopic cylinder 2031 is extended, causing the conveyor structure 2035 to press the screen and frame tightly. At the same time, the compressor 2034 discharges gas into the vortex heat pipe 2036, forming a high-speed rotating vortex. This, together with the vortex heat pipe 2036, forms cold and hot airflows respectively. The hot airflow can preheat the welding area. The position of the plasma arc welding machine 2037 can be adjusted by the adjusting component 201 and the linear ball screw structure 202. The plasma arc welding machine 2037 then performs the welding operation. Meanwhile, the flow divider 2039 discharges cold airflow for rapid cooling. Furthermore, the motor 2032 can drive the top plate 2033 to rotate, adjusting the direction of the plasma arc welding machine 2037, while ensuring that the preheating operation is carried out first, so that the welding operation can proceed smoothly. After welding, the formed screen is conveyed to the cutting conveyor 102. The frame passes through the gap reserved between the cutting conveyor 102 and the welding conveyor 103 to check the welding strength, allowing the frame to smoothly enter the cutting conveyor 102 and be conveyed to the cutting area. At this time, the electric push rod 1063 controls the relative movement of the cutting blade 1062 to cut the screen. After cutting, the lower electric push rod 1063 drives the cutting blade 1062 to retract, while the upper cutting blade 1062 continues to advance downward, so that the inclined surface of the cutting blade 1062 directly bends the excess edge of the screen and squeezes the excess edge to fit the edge of the frame, thus automatically collecting the edge. After collecting the edge, it is automatically output for unloading.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
