Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to workpiece riser cutting, in particular to a water jet cutting device. Background Art
[0002] Valves are commonly used to control parameters such as flow, pressure, and direction of fluids and are widely used in large-scale petrochemical and metallurgical industries. The valve body is a crucial component of the valve, determining its performance and lifespan. Due to its complex shape, valve bodies are typically produced using sand casting. The cast valve body has a riser section, which requires cutting and removing the riser.
[0003] Currently, companies typically use flame or plasma cutting to separate the riser from the workpiece. However, conventional cutting methods such as flame or plasma usually leave part of the riser, making it impossible to separate the riser from the workpiece in one go. The cut section is jagged, and the workpiece surface quality is low. Therefore, after the cutting is completed, the remaining riser needs to be processed a second time. Since the cut section of the riser is jagged, the blade is prone to slippage and breakage during the secondary processing, making the processing difficult. As a result, the existing method of cutting the riser has the problems of difficult cutting and complex processing procedures. In addition, the two processes need to be performed on two different devices, requiring at least two clampings, making the process cumbersome and affecting production efficiency.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or at least two related listed items.
[0034] The water jet cutting device 100 claimed in the present application is used for cutting the pouring riser 201 on the workpiece 200. Here, the workpiece 200 is a sand casting part.
[0035] As Figures 1 to 3As shown, a water jet cutting device 100 provided in one embodiment of the present application includes a rotary clamping mechanism 10 and a water jet cutting mechanism 20. The rotary clamping mechanism 10 is used to clamp a workpiece 200, and the rotary clamping mechanism 10 can adjust the fixed position of the clamped workpiece 200 in the circumferential direction. The water jet cutting mechanism 20 includes a position adjustment component 21 and a water jet 22. The water jet 22 is mounted on the position adjustment component 21, and the water jet 22 can adjust its position under the drive of the position adjustment component 21, so that when the water jet 22 is working, it can cut the pouring riser 201 on the workpiece 200 in a fixed position. In other words, when the water jet cutting device 100 is working, it uses a water jet to cut the pouring riser 201 on the workpiece 200.
[0036] As can be seen from the above, when the water jet cutting device 100 of the present application is in operation, the rotary clamping mechanism 10 adjusts the fixed position of the clamped workpiece 200 in the circumferential direction, and the position adjustment assembly 21 adjusts the position of the water jet 22, enabling the water jet 22 to achieve precise cutting of the riser 201 on the workpiece 200, without any margin. This ensures that the surface quality of the workpiece 200 after cutting is high, the cut section is smooth, and no secondary processing is required. This not only simplifies the cutting process of the riser 201 on the workpiece 200, but also improves production efficiency.
[0037] like Figure 1 、 Figure 2 As shown, the rotary clamping mechanism 10 includes a rotary base 11, a rotary arm 12, and a clamping arm assembly 13. The clamping arm assembly 13 is movably mounted on the rotary arm 12 and is used to clamp / release the workpiece 200. The rotary arm 12 is rotatably mounted on the rotary base 11, and the rotary arm 12 can drive the clamping arm assembly 13 to rotate under the drive of the rotary base 11. In other words, when the rotary clamping mechanism 10 is in operation, the clamping arm assembly 13 can clamp and fix the workpiece 200. The rotary base 11 drives the rotary arm 12 to rotate, so as to adjust the position of the workpiece 200 clamped by the clamping arm assembly 13 in the circumferential direction. Here, the rotary base 11 specifically uses a motor to drive the rotary arm 12 to rotate, so as to adjust the position of the workpiece 200 in the circumferential direction. It should be noted that the specific structures of the swivel base 11 and the swivel arm 12 and the working principle of how the swivel base 11 controls the swivel arm 12 to rotate can adopt existing conventional methods and will not be elaborated here.
[0038] like Figure 2As shown, the clamping arm assembly 13 includes two clamping arms 131, both of which are slidably connected to the rotating arm 12. Moreover, the two clamping arms 131 can move toward or in opposite directions on the rotating arm 12 to clamp / release the workpiece 200. It should be noted that how the two clamping arms 131 move toward or in opposite directions on the rotating arm 12 can adopt existing conventional methods, which will not be elaborated here. It is understood that in other embodiments, the clamping arm assembly 13 can also adopt a method of simultaneously opening or retracting three clamps to control the clamping or release of the workpiece 200, which will not be elaborated here.
[0039] like Figure 1 、 Figure 3 As shown, the position adjustment assembly 21 includes a fixed base 211, to which the water jet 22 is fixedly mounted. The position of the fixed base 211 in both the X-axis and Y-axis directions can be adjusted to adjust the cutting position of the water jet 22. Here, the cutting position specifically refers to the position of the water jet 22 when aligned with the riser 201 on the workpiece 200. It should be noted that the water jet 22 can be fixed to the fixed base 211 using screws, facilitating assembly and disassembly of the water jet 22 from the fixed base 211.
[0040] like Figure 1 、 Figure 3 As shown, the position adjustment assembly 21 includes a gantry 212 and a slider 213. The slider 213 is slidably connected to the gantry 212 in the Y-axis direction and is used to support the fixed seat 211. The gantry 212 can drive the slider 213 and the fixed seat 211 to adjust the position in the X-axis direction. In other words, the position adjustment assembly 21 can use the movement of the gantry 212 in the X-axis direction to adjust the position of the water jet 22 in the X-axis direction, and use the movement of the slider 213 in the Y-axis direction on the gantry 212 to adjust the position of the water jet 22 in the Y-axis direction. Here, the above-mentioned slider 213 can be controlled by a screw nut on the gantry 212 for movement, which will not be elaborated here. It should be noted that the above-mentioned position adjustment assembly 21 can also use a robotic arm to drive the water jet 22 for position adjustment.
[0041] It can be understood that the above-mentioned position adjustment component 21 can use the gantry 212 to elevate the water jet 22, so that the water jet 22 can cut the pouring riser 201 on the workpiece 200 from top to bottom when working, which facilitates the cutting of the pouring riser 201 on the workpiece 200.
[0042] like Figure 1As shown, the water jet cutting device 100 includes a water jet track 30, and a gantry 212 is slidably connected to the gantry 212 in the X-axis direction, so that when the water jet cutting device 100 is in operation, the gantry 212 can reciprocate on the water jet track 30 to adjust the position of the water jet 22 in the X-axis direction. It should be noted that the gantry 212 can also use a screw nut to achieve control of reciprocating movement on the water jet track 30, which will not be elaborated here.
[0043] like Figure 1 、 Figure 3 As shown, the position of the fixing base 211 in the Z-axis direction can be adjusted to adjust the distance between the water jet and the casting riser 201 on the workpiece 200, so that the distance between the tip of the water jet 22 and the casting riser 201 on the workpiece 200 can be adjusted, thereby facilitating the water jet 22 to cut the casting riser 201 on the workpiece 200. It should be noted that the water jet 22 can also be adjusted in position on the fixing base 211 using a screw nut, which will not be elaborated here.
[0044] like Figure 1 As shown, the water jet cutting device 100 also includes a cutting water trough 40, which has an inwardly formed accommodating chamber 41. The accommodating chamber 41 is used to receive the workpiece 200 being cut by the water jet 22. This allows the water generated when the water jet 22 cuts the riser 201 on the workpiece 200 to flow freely during operation, preventing the water from causing contamination. Here, the rotating arm 12 and clamping arm assembly 13 on the rotary clamping mechanism 10 are disposed within the accommodating chamber 41, while the rotating base 11 is disposed outside the cutting water trough 40. Furthermore, the water jet travel track 30 is disposed on both sides of the cutting water trough 40 in the Y-axis direction.
[0045] In addition, the water jet cutting device 100 of the present application further includes a controller (not shown), which is electrically connected to the rotating clamping mechanism 10 and the position adjustment assembly 21, respectively, for controlling the operation of the rotating clamping mechanism 10 and the position adjustment assembly 21. In other words, the water jet cutting device 100 of the present application can be automatically controlled by the controller during operation, which will not be elaborated here.
[0046] It should be noted that the workpiece 200 to be cut by the water jet cutting device 100 of the present application has four pouring risers 201, and the four pouring risers 201 are symmetrically arranged in pairs, so that when the water jet cutting device 100 is working, the rotating clamping mechanism 10 can first clamp the workpiece 200 to a horizontal position, and then use the position adjustment component 21 to drive the water jet 22 to adjust the position in the X-axis direction, the Y-axis direction and the Z-axis direction, drive the water jet 22 to align with the first pouring riser 201 of the workpiece 200, and then turn on the water jet 22 to cut the pouring riser 201 on the workpiece 200. After the cutting is completed, the rotating clamping mechanism 10 drives the workpiece 200 to The water jet 22 is rotated 180° so that the water jet 22 can cut the second riser 201 on the workpiece 200 that is symmetrical to the first riser 201; thereafter, the rotary clamping mechanism 10 rotates the workpiece 200 to a vertical position, and the position adjustment component 21 drives the water jet 22 to adjust its position according to the shape and position of the third riser 201 on the workpiece 200, so that the water jet 22 is aligned with the third riser 201 and then cuts it; then, the rotary clamping mechanism 10 drives the workpiece 200 to rotate 180° again, so that the water jet 22 can cut the fourth riser 201 on the workpiece 200 that is symmetrical to the third riser 201.
[0047] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
