Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a mold high-pressure water jet cutting device. Background Art

[0002] Jet cutting is a plane cutting machine tool that combines an ultra-high pressure water jet generator with a two-dimensional CNC machining platform. It raises the water pressure to a high enough level (above 200MPa) so that the water has great kinetic energy and can penetrate chemical fiber, wood, leather, rubber, etc. If a certain proportion of abrasive is mixed in the high-speed water flow, it can penetrate almost all hard materials such as ceramics, stone, glass, metal, alloy, etc. Under the guidance of the two-dimensional CNC machining platform, the processing starts or ends at any position of the material, and moves at an appropriate speed according to the set trajectory to achieve plane cutting processing of any graphics.

[0003] In the prior art, for example, an ultra-high pressure water jet cutting device is disclosed in publication number CN212240619U, which states: The utility model is an ultra-high pressure water jet cutting device, which is convenient for stirring the water and abrasive material inside the water tank through a stirring shaft and a hand wheel, thereby ensuring the mixing uniformity of the water and abrasive material and improving the cutting performance.

[0004] In actual use, the above-mentioned device supports the cutting material through the internal base plate. During the cutting process, the high-pressure water flow carrying the abrasive will damage the solid base plate, and the waste materials after cutting will also remain on the upper part of the base plate, which will affect the subsequent cutting. In addition, in the above-mentioned device, the abrasive is first mixed into the high-pressure pump. During the transportation process, the nozzle can resist the erosion of the high-pressure water flow and the abrasive for the hard material, but the transportation pipeline is difficult to resist the erosion of the high-pressure water flow and the abrasive, which can easily cause the pipeline to rupture, posing a greater safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a mold high-pressure water jet cutting device, including an outer frame 1, a slide groove 11 is fixedly connected to the side of the outer frame 1, and the guide rail 3 is slidably connected to the outer side of the outer frame 1 through the slide groove 11, and the guide rail 3 can be controlled by an external device, and the electric push rod arranged inside and the slider of the guide rail 3 in the slide groove 11 are fixed to realize the control of the lateral displacement of the water cutter head 31, and the water cutter head 31 can also be longitudinally displaced on the guide rail 3 in the same way, and a drain port 12 is arranged at the bottom of the outer frame 1, and the drain port 12 can discharge the filtered water, and the discharged water can flow back to the booster pump 32 for reuse, and a support plate 13 is fixedly connected to the inner side of the outer frame 1, and the support plate 13 is a vertical plate with a spacing, and during water jet cutting, an ordinary solid plate will be shredded by abrasive and high-pressure water flow, and the support of the support plate 13 can ensure that the water flow passes as much as possible while the water seeps down;

[0028] It also includes a cleaning structure arranged inside the outer frame 1;

[0029] The cleaning structure includes a screw rod 21 arranged in the outer frame 1, the screw rod 21 is rotatably connected in the outer frame 1, a motor 22 fixed on one side of the screw rod 21, a mounting bracket 23 sleeved on the outside of the motor 22, the mounting bracket 23 is fixed on the outside of the outer frame 1, a round sleeve 24 arranged on the outside of the screw rod 21, the round sleeve 24 connected to the screw rod 21 has a thread meshing with the screw rod 21 inside, the round sleeve 24 connected to the round rod 27 has no thread inside, a scraper 25 fixed to the round sleeve 24, the upper part of the scraper 25 is in contact with the upper part of the support plate 13, and the scraping teeth 26 are fixed on the lower side of the scraper 25, and the scraping teeth 26 can extend into the gap between the support plates 13.

[0030] A round rod 27 is provided on one side of the scraper 25 , and a discharge port 28 is provided on one side of the outer frame 1 . A square pipe is connected to the lower side of the discharge port 28 , which can cooperate with the scraper 25 to discharge the cut waste.

[0031] A guide rail 3 is movably connected to one side of the outer frame 1 , and a water jet head 31 is movably connected to the guide rail 3 . The water jet head 31 can be controlled by an external device to control the water inlet and outlet and the sliding along the guide rail 3 .

[0032] A booster pump 32 is fixedly connected to one side of the outer frame 1. The booster pump 32 is connected to an external water source to pressurize the water and then inject it into the water knife head 31. In addition, the drain outlet 12 can extend a pipeline to connect to the filtering device in the booster pump 32, and then the booster pump 32 pressurizes the water and inputs it into the water knife head 31. A feeding structure is set on the inner side of the water knife head 31.

[0033] During use, after the equipment completes cutting, the operator takes away the mold that has completed cutting and starts the motor 22. The motor 22 drives the screw 21 to rotate. Because the round sleeve 24 and the screw 21 are threadedly connected, the round sleeve 24 will move along the direction of the screw 21, and the other round sleeve 24 is slidably connected to the round rod 27 to limit the position of the scraper 25 to ensure that the scraper 25 remains parallel. Therefore, the scraper 25, driven by the screw 21, can cooperate with the scraping teeth 26 that penetrate deep into the gap between the support plates 13 to clean the waste located on the support plate 13 and in the gap between the support plates 13, sweep it into the discharge port 28, and discharge it from the equipment to ensure that there is no waste in the equipment before the next cutting to cause an impact. The scraper 25 only needs to make a single stroke, and then it can stay on the side where the operation is completed. When scraping the lower side, start the motor 22 for a single-stroke movement.

[0034] Example 2

[0035] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the feeding structure includes a through hole 41 arranged on the inner side of the water knife head 31, the through hole 41 is for the guide rail 3 to pass through, a shunt pipe 42 opened on the inner side of the water knife head 31, a part of the shunt pipe 42 is directly connected to the nozzle 43, and the other part is connected to the trigger tube 44, the nozzle 43 fixed on the lower side of the water knife head 31, the trigger tube 44 fixed on the water knife head 31, a spring 45 fixed on the inner side of the trigger tube 44, and a piston 46 fixed to the spring 45. The piston 46 is movably connected in the trigger tube 44. The piston 46 has a thinner end. When the piston 46 is squeezed by the water flow, the end will enter the circular groove opened in the trigger tube 44, thereby opening the straight tube connected to the feeding bin 47 at the lower side of the trigger tube 44.

[0036] A feed bin 47 is provided at the lower side of the trigger tube 44. The feed bin 47 can accommodate abrasives and bring the abrasives into the nozzle 43 through high-speed water flow. An injector 48 is provided at the upper side of the feed bin 47. The injector 48 can add abrasives into the feed bin 47. The injector 48 is connected to an external device for storing abrasives.

[0037] During use, when the water flow is input into the water knife head 31 by the booster pump 32, the water flow is divided into two streams. One part passes through the diverter pipe 42 and is directly ejected through the nozzle 43, and the other part passes through the trigger tube 44. When this part of the water flow passes through the trigger tube 44, the piston 46 will be squeezed into the circular groove at the end of the trigger tube 44. At this time, the spring 45 contracts to open the straight pipe connecting the trigger tube 44 and the feed bin 47. At this time, the water flow will enter the feed bin 47 through the straight pipe. The feed bin 47 has abrasives injected by the injector 48. The water flow will carry the abrasives in this part of the feed bin 47 into the nozzle 43 and merge with the previously diverted water flow, thereby being ejected from the nozzle 43 to start cutting the mold. The process can protect the pipeline that transports the high-pressure water flow to prevent it from being cut and broken by the abrasive carried by the high-pressure water flow, thereby causing harm to the operator.

[0038] The remaining structures are the same as those of Example 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
