Description

Technical Field

[0001] The invention belongs to the technical field of valve welding, in particular to a casting valve welding device. Background Art

[0002] Industrial valves are essential accessories for controlling the flow of media in industrial pipelines. They can be used to control the flow of various fluids, including air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. A valve consists of three main components: the valve body, the opening and closing mechanism, and the bonnet. This article focuses on the structural features of our company's commonly used valves and precautions for their proper use. The valve casting process requires a die-casting machine, a series of industrial casting machines that hydraulically inject molten metal under pressure into a mold, where it cools and forms a solid metal casting after the mold is opened. These machines were originally used for die-casting lead type.

[0003] A patent with publication number CN116511453B discloses a valve casting device with a pressure buffer structure, including a casting bracket, a hydraulic station welded to one side of the casting bracket, a sliding rail welded to the side of the casting bracket away from the hydraulic station, a pressure plate fixedly installed on the top of the casting bracket close to the hydraulic station by bolts, and a buffer plate fixedly installed on the top of the casting bracket away from the hydraulic station by bolts. The present invention can visualize the buffer pressure and automatically adjust the buffer pressure to ensure that the buffer force reaches the condition of stably filling the mold cavity, so as to solve the problem that the existing buffer process is too comprehensive and too soft, and the die-casting machine will not receive feedback from the reverse support force, which will cause the parts die-cast by the die-casting machine to be unable to eliminate the gap. At present, the buffer force of the entire buffer process is not visible, and the buffer pressure cannot be automatically adjusted by digitization, and the filling degree of the metal liquid cannot be guaranteed, which easily reduces the strength and internal quality of the casting.

[0004] In the current existing technology, when welding existing valves, in order to maintain the horizontal angle between the two sets of valve pipes so that they do not tilt due to welding, the valves need to be fixed and welded by a mechanical welding arm. However, during the welding process, the valves need to be clamped, fixed, positioned, welded, disassembled, and replaced with new valve components. This makes the entire welding process more cumbersome and involves numerous cumbersome steps and repetitive steps.

[0005] To this end, the present invention provides a casting valve welding device. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows: 1. The present invention relates to a casting valve welding device. After the valve limit frame and the push frame are filled with multiple valves, the bottom valve is positioned, aligned, and welded. Then, a pair of L-shaped toggle levers are rotated in conjunction with a motor. The raised ends of the L-shaped toggle levers push the push rods on the outer surfaces of the overlapping push plates, thereby squeezing the elastic wire.

A casting valve welding device described in the present invention, when the new valve is horizontally overlapped under the limitation of the overlap push plate, the slider slides on the surface of the slide rod, and the hydraulic rod on one end of the second motor is inserted into the interior of the valve. At this time, the hydraulic rod is extended, so that the conical push block on the output end of the hydraulic rod squeezes and pushes the inner wall surface of the swing plate, and the swing plate spreads to the surroundings, and the extrusion anti-slip soft strip on the outer surface of the swing plate is squeezed and fitted on the inner wall surface of the valve. At this time, the arc welder is used to weld the joints of the two sets of valves, so that the two sets of valves form a whole. At the same time, the motor 2 is used to rotate the hydraulic rod, thereby driving the valves on both sides to rotate together and perform rotation welding at the output end of the arc welder; When the valve is in the closed position, the two valves are moved downwards, and the valve is in the closed position ...

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 10 As shown, a casting valve welding device according to an embodiment of the present invention includes a processing and welding table 11 and a valve extrusion limit frame 13 arranged on the outer surface of the top of the processing and welding table 11, a valve limit frame 112 and a push frame 115 are respectively arranged on the top surface of the processing and welding table 11, and the positions of multiple groups of valve extrusion limit frames 13 are respectively arranged on the outer surfaces of the valve limit frame 112 and the push frame 115, the valve 15 is movably sleeved on the inner wall surface of the valve limit frame 112 and the push frame 115, two groups of elastic wires 131 are fixedly connected to the inner wall surface of the valve extrusion limit frame 13, one end of the two groups of elastic wires 131 is respectively fixedly connected to a push strip 139 and an overlapping push plate 132, and the outer surface of the overlapping push plate 132 is fixedly connected The push rod 135 is overlapped on one side surface of the push plate 132 and is respectively provided with an arc groove 133 and an R-shaped fillet 134 that are movably overlapped on the outer surface of the valve 15 at the upper and lower edge positions. A push plate 138 is fixedly connected to one end of the push strip 139. A limit rod 2 137 that is movably sleeved on the inner wall of the push plate 138 is fixedly connected to the inner wall of the valve extrusion limit frame 13. One end of the limit rod 2 137 is fixedly connected to an overlapping ring 1310 that is movably overlapped on the outer surface of the valve 15. A push rod 2 136 that is movably overlapped on the inner wall of the push strip 139 is fixedly connected to one side surface of the overlapping push plate 132. An L-shaped toggle rod 1110 is movably overlapped on the outer surface of the push rod 135.

[0023] The two sets of valves 15 are respectively clamped into the inner wall surfaces of the valve limit frame 112 and the push frame 115. At this time, the overlapping arc grooves 133 on the outer surface of the overlapping push plate 132 are fitted on the outer surface of the valve 15. The fitting surface of the overlapping arc grooves 133 is tightly fitted on the outer surface of the valve 15, so that the valve 15 is at a horizontal angle under the restriction of the overlapping push plate 132 and the valve limit frame 112, thereby reducing the possibility that the valve 15 will tilt and be unable to maintain a horizontal angle due to gravity. When the valve 15 overlaps the top surface of the overlapping arc groove 133, the push plate 138 is pushed by the elastic force of the elastic wire 131, so that the overlapping ring 1310 on the outer surface of the valve 15 can overlap the top surface of the valve 15. The overlapping arc groove 133, the overlapping push plate 132 and the overlapping ring 1310 support and limit the position of the valve 15, greatly reducing the possibility of slight tilting of the valve 15 during subsequent welding. After the valve limiting frame 112 and the pushing frame 115 are filled with multiple groups of valves 15, and the bottom valve 15 is positioned, aligned, and welded, the motor 119 is used to rotate the L-shaped toggle rod 1110, and the raised end of the L-shaped toggle rod 1110 is used to push the push rod 135 on the outer surface of the overlapping push plate 132, thereby squeezing the elastic wire 131. When the two overlapping push plates 132 are extended to both sides, the valve 15 will be pressed down by its own weight and guided by the R-shaped fillet 134, so that the welded valve 15 will detach from the surface of the overlapping push plate 132. When the overlapping push plate 132 is extended to both sides, the overlapping push plate 132 will drive the second push rod 136 to slide on the inner wall of the push strip 139. At this time, the valve 15 of the second to last layer will remain in place under the obstruction of the overlapping ring 1310, and the valve 15 at the bottom layer will move downward under the gradual expansion of the overlapping push plate 132, and open the gap between the two groups of valves 15. When the second push rod 136 is attached to the wall of one side of the push strip 139, it will push the push plate 138 to one side. At this time, the valve 15 will gradually move downward in the extended gap of the overlapping ring 1310. When the valve 15 passes the middle position of the overlapping ring 1310, the L-shaped toggle rod 1110 is just detached from the surface of the motor 119, and under the reverse push of the elastic wire 131, the two overlapping push plates 132 are connected and closed. At this time, the valve 15 will detach from the surface of the overlapping ring 1310 under its own gravity, and under the closing of the overlapping push plates 132, the position is limited and subsequently supported.

[0024] like Figures 1 to 10As shown, a blanking trough 111 is provided on the top surface of the processing and welding table 11, a motor 119 is fixedly installed on the top surface of the processing and welding table 11, one end of the L-shaped toggle rod 1110 is fixedly connected to the output end surface of the motor 119, a limiting groove 118 is fixedly installed on the top surface of the processing and welding table 11, the output end of the limiting groove 118 is fixedly connected to the outer surface of the pushing frame 115, a side surface of the pushing frame 115 is fixedly connected to the limiting rod 116 at the bottom edge position, a limiting groove 117 is provided on the outer surface of the processing and welding table 11 and at the bottom edge position of the valve limiting frame 112, the outer surface of the limiting rod 116 is movably sleeved on the inner wall of the limiting groove 117, the valve limiting frame 11 2 is fixedly connected to a limit sleeve 113 on one side surface, and a slide rod 114 is fixedly connected to the inner wall surface of the limit sleeve 113. The slider 12 is movably sleeved on the outer surface of the slide rod 114. The inner wall surface of the slider 12 is fixedly connected to the motor 2 121, and the output end of the motor 2 121 is fixedly connected to the hydraulic rod 122, and the output end of the hydraulic rod 122 is fixedly connected to the conical push block 123. One end surface of the motor 2 121 is fixedly connected to a swing plate 124, and the outer surface of the conical push block 123 is movably overlapped on the inner wall surface of the swing plate 124. The outer surface of the swing plate 124 is fixedly connected to an extrusion anti-slip soft strip 125, and the outer surface of the extrusion anti-slip soft strip 125 is movably overlapped on the inner wall surface of the valve 15.

[0025] When the new valve 15 is horizontally overlapped under the limitation of the overlapping push plate 132, the slider 12 is cooperated to slide on the surface of the slide rod 114, and the hydraulic rod 122 on one end of the motor 2 121 is inserted into the interior of the valve 15. At this time, the hydraulic rod 122 is extended, so that the conical push block 123 on the output end of the hydraulic rod 122 squeezes and pushes the inner wall of the swing plate 124, and the swing plate 124 spreads to the surroundings, and the extrusion anti-slip soft strip 125 on the outer surface of the swing plate 124 is squeezed and fitted on the inner wall of the valve 15. At this time, the arc welder 14 is cooperated to weld the joints of the two groups of valves 15, so that the two groups of valves 15 form a whole. At the same time, the motor 2 121 is cooperated to rotate the hydraulic rod 122, thereby driving the valves 15 on both sides to rotate together and perform rotation welding at the output end of the arc welder 14.

[0026] Working principle: The two sets of valves 15 are respectively snapped into the inner wall surfaces of the valve limit frame 112 and the push frame 115. At this time, the overlapping arc grooves 133 on the outer surface of the overlapping push plate 132 are fitted on the outer surface of the valve 15, and the fitting surface of the overlapping arc grooves 133 is tightly fitted on the outer surface of the valve 15, so that the valve 15 is at a horizontal angle under the limitation of the overlapping push plate 132 and the valve limit frame 112, reducing the situation where the valve 15 will tilt and be unable to maintain a horizontal angle due to gravity. When the valve 15 overlaps the top surface of the overlapping arc groove 133, the push plate 138 is pushed by the elastic force of the elastic wire 131, so that the overlapping ring 1310 on the outer surface of the valve 15 can overlap the top surface of the valve 15. The overlapping arc groove 133, the overlapping push plate 132 and the overlapping ring 1310 support and limit the position of the valve 15, greatly reducing the possibility of slight tilting of the valve 15 during subsequent welding. After the valve limiting frame 112 and the pushing frame 115 are filled with multiple groups of valves 15, and the bottom valve 15 is positioned, aligned, and welded, the motor 119 is used to rotate the L-shaped toggle rod 1110, and the raised end of the L-shaped toggle rod 1110 is used to push the push rod 135 on the outer surface of the overlapping push plate 132, thereby squeezing the elastic wire 131. When the two overlapping push plates 132 are extended to both sides, the valve 15 will be pressed down by its own weight and guided by the R-shaped fillet 134, so that the welded valve 15 will detach from the surface of the overlapping push plate 132. When the overlapping push plate 132 is extended to both sides, the overlapping push plate 132 will drive the second push rod 136 to slide on the inner wall of the push strip 139. At this time, the valve 15 of the second to last layer will remain in place under the obstruction of the overlapping ring 1310, and the valve 15 at the bottom layer will move downward under the gradual expansion of the overlapping push plate 132, and open the gap between the two groups of valves 15. When the second push rod 136 is attached to the wall of one side of the push strip 139, it will push the push plate 138 to one side. At this time, the valve 15 will gradually move downward in the extended gap of the overlapping ring 1310. When the valve 15 passes the middle position of the overlapping ring 1310, the L-shaped toggle rod 1110 just separates from the surface of the motor 119 and, under the reverse push of the elastic wire 131, connects and closes the two overlapping push plates 132. At this time, the valve 15 will separate from the surface of the overlapping ring 1310 under its own weight and, under the closing of the overlapping push plates 132, perform position definition and subsequent support processing. When the new valve 15 is horizontally overlapped under the limitation of the overlapping push plate 132, the slider 12 is cooperated to slide on the surface of the slide rod 114, and the hydraulic rod 122 on one end of the motor 2 121 is inserted into the interior of the valve 15. At this time, the hydraulic rod 122 is extended, so that the conical push block 123 on the output end of the hydraulic rod 122 squeezes and pushes the inner wall of the swing plate 124, and the swing plate 124 spreads to the surroundings, and the extrusion anti-slip soft strip 125 on the outer surface of the swing plate 124 is squeezed and fitted on the inner wall of the valve 15. At this time, the arc welder 14 is cooperated to weld the joints of the two groups of valves 15, so that the two groups of valves 15 form a whole. At the same time, the motor 2 121 is cooperated to rotate the hydraulic rod 122, thereby driving the valves 15 on both sides to rotate together and perform rotation welding at the output end of the arc welder 14.
