Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a support removal tool for 3D printing pipelines and step products. Background Art

[0002] Currently, 3D printing technology has been widely used to manufacture components with internal support requirements, such as pipelines and complex step structures. During the printing process, in order to support the stability and integrity of the structure, support structures are set in the design. These structures are usually made of the same or similar materials as the main material. Once printing is completed, these support structures must be completely removed to ensure the internal patency of the component and the integrity of the structure.

[0003] However, existing support removal tools face serious limitations, mainly due to the inability to effectively access and process support structures inside components. This difficulty is particularly prominent in situations where the internal spaces are small or complex, such as pipelines and complex step structures, where traditional tools have difficulty traversing these internal channels or gaps. This not only increases the time and cost of removing support structures, but can also lead to problems with residual supports inside the structure, affecting the quality and performance of the final product.

[0004] In summary, there is an urgent need for a 3D printed pipe and step product support removal tool that can enter the inner wall of the pipe and the step structure and safely remove the support. Utility Model Content

[0005] The purpose of the invention of the utility model is to provide a support removal tool for 3D printed pipes and step products, which can enter the inner wall of the pipe and the inside of the step structure and safely remove the support.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Embodiment 1

[0021] A 3D printing pipe and step product support removal tool, including a pipe component 2, a connecting piece 3 is inserted through the pipe component 2, one end of the connecting piece 3 is connected to the output end of the driving device 1, and the other end is connected to the grinding piece 4. The connecting piece 3 is used to expand the grinding range, the pipe component 2 is used to support the connecting piece 3, and the driving device 1 drives the grinding piece 4 to perform grinding through the connecting piece 3. The pipe component 2 includes an elbow 21, a first hollow pipe 22 and a second hollow pipe 23. One end of the elbow 21 is detachably connected to the first hollow pipe 22, and the other end is detachably connected to the second hollow pipe 23. Among them, the pipe component 2 can be assembled according to the shape of the pipe to be ground. The connecting piece 3 is a steel wire soft line. One end of the steel wire soft line is connected to the output end of the driving device 1, and the other end extends out of the pipe component 2 and is connected to the grinding piece 4. After the pipe component 2 is assembled, the steel wire soft line is inserted and connected to the output end of the driving device 1 and the grinding piece 4 respectively. The shapes of the first hollow pipe 22 and the second hollow pipe 23 can be selected according to the actual situation.

[0022] When this application is in use, first assemble this application according to the shape of the pipe to be ground (usually, the pipe component structure shown can be applied to most pipe structures to be ground). After assembling this application, insert this application into the inner wall of the pipe or the inside of the step structure where the support needs to be removed, and turn on the driving device 1. The driving device 1 drives the steel wire soft line to rotate, and then drives the grinding piece 4 to rotate, so as to remove and grind the support structure inside the pipe. If the inner diameter of the pipe is too small and it cannot be inserted during the grinding process, the pipe component can be replaced to adapt to the inner diameter of the pipe, so as to further perform support removal and grinding. By setting the steel wire soft line and the pipe component, this application further extends the grinding range and can adapt to the structures of some pipes to a certain extent. It can grind and remove the support structures on the inner wall of the pipe and the inner walls of some complex structures, and at the same time endow the characteristics of the 3D printing product material. The process of gradually removing the support by inserting this application into the inner wall of the pipe can further ensure that while ensuring the structural integrity, the printing efficiency and manufacturing quality are improved. Figure 1

[0023] Further, a rubber plug 5 is provided at one end of the pipe component 2 close to the grinding piece 4. The rubber plug 5 is used to pass through and fix the steel wire soft line. As Figure 1 described, it is arranged inside one end of the pipe component 2. Specifically, a channel is provided through the center of the rubber plug 5, and the steel wire soft line can rotate freely in the channel. At the same time, materials such as sponge bodies that can fix the steel wire soft line within a certain range but do not limit the free rotation of the steel wire soft line can also be set.

[0024] Specifically, the driving device 1 is an electric grinder, and the output end of the electric grinder is connected to the flexible steel wire. The model of the electric grinder can be selected as MNTO70306, and the first hollow tube 22 is sleeved on the output end of the electric grinder.

[0025] Specifically, the grinding member 4 is a grinding wheel head. The grinding wheel head has a large removal capacity, high precision, and long service life.
