[0034] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] like Figures 1 to 4 As shown, the utility model provides an angle forming device 100, which is used for bending the nozzle 223 of the water knife 200. It can be understood that the water knife 200 includes a shell 210 and a pressure pipe 220, the shell 210 has a concave space 211 formed at the cutter head, and the pressure pipe 220 includes a high-pressure pipeline 221, a bending portion 222 and a nozzle 223 connected in sequence, so as to focus the high-pressure water flow and form a high-speed water jet for cutting to be ejected from the nozzle 223.

[0036] like Figures 4 to 7As shown, the bevel forming device 100 in this embodiment includes a first handle 110, a second handle 120, an inclined top block 130 and a connecting shaft 140. The first handle 110 includes a first hinged portion 111 hinged to the second handle 120, and the second handle 120 includes a second hinged portion 121 hinged to the first handle 110. The first hinged portion 111 and the second hinged portion 121 are connected by the connecting shaft 140, so that the first handle 110 and the second handle 120 can be opened and closed, thereby realizing the first The handle 110 and the second handle 120 are opened and closed, and the inclined lift block 130 is arranged at one end of the first handle 110; the inclined lift block 130 has a first mating side 131 for mating with the high-pressure pipeline 221, a second mating side 132 for mating with the bending portion 222, and a third mating side 133 for mating with the nozzle 223. The first mating side 131 is connected to the third mating side 133 through the second mating side 132, and a first inclination angle is formed between the third mating side 133 and the first mating side 131.

[0037] Based on the above structure, during operation, the bevel forming device 100 is used to extend the beveled top block 130 into the concave space 211 at the water jet outlet of the cutter head of the water jet 200, and then the first handle 110 and the second handle 120 are clamped tightly so that one end of the second handle 120 abuts against the shell 210 of the water jet 200, forcing the beveled top block 130 to slide completely into the concave space 211 of the cutter head. At this time, the first mating side 131 abuts against the high-pressure pipeline 221, the second mating side 132 abuts against the elbow pipe, and the third mating side 133 abuts against the nozzle 223. Due to the setting of the first inclination angle, the nozzle 223 will be bent as the beveled top block 130 moves until it is tilted and fits to the first inclination angle, and then the first handle 110 and the second handle 120 are opened and moved away; at this time, the nozzle 223 is made into the required bevel angle state, and the direction of its water jet becomes a certain bevel angle.

[0038] In some embodiments, the first mating side 131 is recessed to form a first groove 1311 that matches the high-pressure pipeline 221, so as to accurately match and fix it on the circumference of the high-pressure pipeline 221. When the inclined top block 130 contacts the high-pressure pipeline 221, the groove can closely fit the outer contour of the high-pressure pipeline 221, provide good enclosure and support force, ensure a stable connection between the two, and when applying force to bend the nozzle 223, it can effectively disperse the force to avoid directly acting on the outer wall of the high-pressure pipeline 221 and causing damage to it. The second mating side 132 is recessed to form a second groove 1321 that matches the bending portion 222, which also adopts a recessed shape to adapt to the shape of the bending portion 222, so that the inclined top block 130 is more firmly combined with the bending portion 222, and can ensure the stability and smoothness of the bending portion 222 when adjusting the angle, while preventing mechanical damage caused by stress concentration. The third matching side 133 is recessed to form a third groove 1331 matched with the nozzle 223 to ensure that the nozzle 223 can be accurately embedded in the inclined top block 130, thereby achieving precise control of the bending angle of the nozzle 223.

[0039] In some embodiments, the third mating side 133 is recessed to form a first avoidance groove 1332, which is disposed on the side of the third groove 1331 away from the second mating side 132 to provide a safe space buffer area when adjusting the angle of the nozzle 223, especially when performing bending operations.

[0040] Specifically, during the operation of the water jet 200 device, especially when the angle of the nozzle 223 is changed, the nozzle may contact the inclined ejector block 130 due to mechanical stress and movement, thereby generating the risk of extrusion or collision, which may damage the delicate and fragile nozzle. By providing the first avoidance groove 1332 in the third mating side 133, the nozzle can be effectively prevented from directly contacting the inclined ejector block 130 made of hard material, thereby reducing potential damage caused by physical impact.

[0041] In some embodiments, the second mating side 132 has an arc structure that matches the bent portion 222. The arc structure is used to match the bent portion 222 to carry the bent portion 222 and fit with the bent portion 222, and it is matched with the first tilt angle so that the third mating side 133 carries the nozzle 223 and fits with the nozzle 223; in addition, the arc structure can also be used as a transition to effectively reduce the stress concentration phenomenon at right angles or sharp corners, and at the same time avoid the possible scratches or collision damage to the surface of the component caused by the straight edges and right angles, especially for precision components such as nozzles working in high-pressure environments. It has a good protective effect.

[0042] In some embodiments, the tilting lift block 130 is detachably connected to the first handle 110 to facilitate replacement of different tilting lift blocks 130 as needed.

[0043] like Figure 7 As shown, in some embodiments, the tilted lift block 130 further has a first connection side 134 connected to one end of the first handle 110 , and both sides of the first connection side 134 are respectively connected to the first mating side 131 and the third mating side 133 .

[0044] In this embodiment, the first mating side 131 and the third mating side 133 of the inclined ejector block 130 are organically combined together through the first connecting side 134, and form an integral linkage structure with the second mating side 132, ensuring that during operation, when adjusting the handle, the different mating sides on the inclined ejector block 130 can be synchronously driven to work together. In addition, when the operator changes the angle of the inclined ejector block 130 through the first handle 110, the first connecting side 134 plays a role in transmitting torque, ensuring that the force applied to the first handle 110 can be effectively converted into the force applied to bend the nozzle 223. In this embodiment, the first connecting side 134 is detachably connected to the first handle 110, so that different inclined ejector blocks 130 can be replaced to bend the angle of the nozzle 223.

[0045] like Figure 8 As shown, in another embodiment, the inclined lift block 130 also has a second connection side 135 that can be detachably connected to the first handle 110 and a third connection side 136 that can be detachably connected to the first handle 110, and the two sides of the second connection side 135 are respectively connected to the first mating side 131 and the third connection side 136, and the two sides of the third connection side 136 are respectively connected to the second connection side 135 and the third mating side 133; a second inclination angle is formed between the second connection side 135 and the third connection side 136.

[0046] When the second connection side 135 is connected to the first handle 110, when the operator rotates the first handle 110, the second connection side 135 plays a role of transmitting torque, ensuring that the force applied to the first handle 110 can be effectively converted into a force applied to bend the nozzle 223. When the third connection side 136 is connected to the first handle 110, when the operator rotates the first handle 110, the third connection side 136 plays a role of transmitting torque, ensuring that the force applied to the first handle 110 can be effectively converted into a force applied to bend the nozzle 223.

[0047] The design of the second inclination angle helps to optimize the working performance of the inclined lift block 130 so as to meet the placement of the inclined lift block 130 at different angles and adapt to the bending of the nozzle 223 according to different requirements.

[0048] like Fig. 9As shown, in some embodiments, the inclined top block 130 also has a fourth mating side 137 for mating with the high-pressure pipeline 221, a fifth mating side 138 for mating with the bending portion 222, and a sixth mating side 139 for mating with the nozzle 223. The fourth mating side 137 is connected to the sixth mating side 139 through the fifth mating side 138, and the sixth mating side 139 and the fourth mating side 137 are arranged parallel to each other, ensuring that when the tension adjustment block 150 is installed in place, it can simultaneously adapt to and fix the three key parts of the high-pressure pipeline 221, the bending portion 222 and the nozzle 223.

[0049] In addition, one end of the fourth mating side 137 away from the fifth mating side 138 is connected to one end of the first mating side 131 away from the second mating side 132, and the fourth mating side 137 and the first mating side 131 form a third inclination angle, so that when replacing, the installation positions of the first mating side 131, the second mating side 132 and the third mating side 133 are adapted to the positions of the high-pressure pipeline 221, the bending portion 222 and the nozzle 223.

[0050] When using the device, first install the first mating side 131 on the first handle 110, and then insert it into the concave space 211 corresponding to the water jet outlet position inside the water jet 200 cutter head. The operator then clamps the first handle 110 and the second handle 120 tightly, so that one end of the second handle 120 fits tightly against the water jet 200 housing 210, thereby pushing the inclined top block 130 to completely slide into the concave space 211 of the cutter head. When the inclined top block 130 is fully in place, the fourth mating side 137 on it will tightly abut against the high-pressure pipeline 221, the fifth mating side 138 will be tightly combined with the elbow pipe, and the sixth mating side 139 will contact and fix the nozzle 223 accordingly, and then the nozzle 223 will be loosened to facilitate the subsequent replacement of the inclined top block 130 for the bending of the nozzle 223. Then, the fourth mating side 137 is installed on the first handle 110, and the inclined top block 130 is extended into the concave space 211 at the water jet outlet of the cutter head of the water jet 200. Then, the first handle 110 and the second handle 120 are clamped tightly so that one end of the second handle 120 abuts against the shell 210 of the water jet 200, forcing the inclined top block 130 to slide completely into the concave space 211 of the cutter head. At this time, the first mating side 131 abuts against the high-pressure pipeline 221, the second mating side 132 abuts against the elbow pipe, and the third mating side 133 abuts against the nozzle 223. Due to the setting of the first inclination angle, the nozzle 223 will be bent as the inclined top block 130 moves until it is inclined to fit the first inclination angle, and then the first handle 110 and the second handle 120 are opened and moved away; at this time, the nozzle 223 is made into the required inclination angle state, and its water jet direction becomes a certain inclination angle.

[0051] In some embodiments, the fourth mating side 137 is recessed to form a fourth groove matched with the high-pressure pipeline 221 so as to be precisely matched and fixed on the peripheral side of the high-pressure pipeline 221 . When the inclined top block 130 contacts the high-pressure pipeline 221, the groove can fit closely to the outer contour of the high-pressure pipeline 221, provide good enclosure and support forces, ensure a stable connection between the two, and when force is applied to bend the nozzle 223, the force can be effectively dispersed to avoid directly acting on the outer wall of the high-pressure pipeline 221 and causing damage to it; the fifth mating side 138 is recessed to form a fifth groove 1381 that is compatible with the bending portion 222, which also adopts a recessed shape to adapt to the shape of the bending portion 222, so that the inclined top block 130 is more firmly combined with the bending portion 222, and can ensure the stability and smoothness of the position of the bending portion 222 when adjusting the angle, while preventing mechanical damage caused by stress concentration; the sixth mating side 139 is recessed to form a sixth groove 1391 that is compatible with the nozzle 223, so as to ensure that the nozzle 223 can be accurately embedded in the inclined top block 130, thereby achieving tightness adjustment of the nozzle 223.

[0052] In addition, the sixth mating side 139 is recessed to form a second escape groove 1392 , which is disposed on a side of the sixth groove 1391 away from the fifth mating side 138 , so as to provide a safe space buffer area when adjusting the tightness of the nozzle 223 .

[0053] It can be understood that the fourth mating side 137 and the first mating side 131 in this embodiment are provided with a structure that is detachably connected to the first handle 110. In addition, since the fourth mating side 137 and the first mating side 131 need to cooperate with the high-pressure pipeline 221, the detachable connection structure between the fourth mating side 137 and the first mating side 131 in this embodiment is preferably arranged on the top wall of the fourth mating side 137 and the top wall of the first mating side 131 to avoid interference during mating.

[0054] like Fig.10 As shown, in some embodiments, a tension adjustment block 150 is further included, and the tension adjustment block 150 is detachably connected to one end of the first handle 110. The tension adjustment block 150 has a seventh mating side 151 for mating with the high-pressure pipeline 221, an eighth mating side 152 for mating with the bending portion 222, and a ninth mating side 153 for mating with the nozzle 223. The seventh mating side 151 is connected to the ninth mating side 153 through the eighth mating side 152, and the seventh mating side 151 and the ninth mating side 153 are arranged parallel to each other, ensuring that when the tension adjustment block 150 is installed in place, it can simultaneously adapt to and fix the three key parts of the high-pressure pipeline 221, the bending portion 222 and the nozzle 223.

[0055] When using the device, first install the tension adjustment block 150 on the first handle 110, and then insert it into the concave space 211 corresponding to the water jet outlet position inside the water jet 200 cutter head. The operator then clamps the first handle 110 and the second handle 120 tightly, so that one end of the second handle 120 fits tightly against the water jet 200 housing 210, thereby pushing the tension adjustment block 150 to completely slide into the concave space 211 of the cutter head. When the tension adjustment block 150 is fully in place, the seventh mating side 151 on it will tightly abut against the high-pressure pipeline 221, the eighth mating side 152 will be tightly combined with the elbow pipe, and the ninth mating side 153 will contact and fix the nozzle 223 accordingly, and then the installation of the nozzle 223 is loosened to facilitate the subsequent replacement of the inclined top block 130 for the bending of the nozzle 223.

[0056] In some embodiments, the seventh mating side 151 is recessed to form a seventh groove 1511 adapted to the high-pressure pipeline 221 so as to be precisely matched and fixed to the peripheral side of the high-pressure pipeline 221 . When the tension adjustment block 150 contacts the high-pressure pipeline 221, the groove can fit closely to the outer contour of the high-pressure pipeline 221, provide good enclosure and support forces, ensure a stable connection between the two, and when applying force to bend the nozzle 223, the force can be effectively dispersed to avoid directly acting on the outer wall of the high-pressure pipeline 221 and causing damage to it; the eighth matching side 152 is recessed to form an eighth groove 1521 that is compatible with the bending portion 222, which also adopts a recessed shape to adapt to the shape of the bending portion 222, so that the tension adjustment block 150 is more firmly combined with the bending portion 222, and can ensure the stability and smoothness of the bending portion 222 when adjusting the angle, while preventing mechanical damage caused by stress concentration; the ninth matching side 153 is recessed to form a ninth groove 1531 that is compatible with the nozzle 223, so as to ensure that the nozzle 223 can be accurately embedded in the tension adjustment block 150, thereby realizing the tension adjustment of the nozzle 223.

[0057] In addition, the ninth mating side 153 is recessed to form a third escape groove 1532 , which is disposed on a side of the ninth groove 1531 away from the eighth mating side 152 , so as to provide a safe space buffer area when adjusting the tightness of the nozzle 223 .

[0058] In summary, the embodiment of the utility model provides an angled forming device 100, which can make the nozzle 223 into a desired angled state, and the direction of the water jet is changed to be ejected at a certain angle.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
