[0023] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0024] [Example 1]

[0025] A hose punching device, such as Figure 1 , including a base 1, a punching body 2, a core rod 3 and a fixing body 4.

[0026] like Figure 2 The base 1 is provided with a tube groove 14 and a core rod groove 12 on the same axis, which are used to place the hose to be punched and the core rod 3 respectively, so that the hose and the core rod 3 can move and mate along the set trajectory. The material of the base 1 is preferably POM material, which can reduce the impact of the tool on the entire device during punching. It is processed by a CNC lathe and the surface is machined after processing to make the surface smoother.

[0027] The tube groove 14 on the base 1 is a circular groove, and the mandrel groove 12 is a semi-hexagonal groove. The two grooves are connected, and there is a step at the connection. One side of the mandrel groove 12 is slightly higher than the side of the tube groove 14, which is convenient for inserting the mandrel 3 into the hose. The design of the semi-hexagonal groove can prevent the mandrel 3 from deflecting. A fixing ring 13 is provided on the base 1. The fixing ring 13 and the mandrel groove 12 constitute a surrounding positioning of the mandrel 3. The fixing ring 13 plays a role in fixing and preventing the regular hexagonal mandrel 3 from warping.

[0028] Position adjustment grooves 11 are provided on both sides of the tube groove 14 on the base 1, which can be square grooves. The extension direction of the position adjustment grooves 11 is parallel to the axis of the tube groove 14 and the core rod groove 12, and the punching body 2 can be adjusted along the position adjustment grooves 11.

[0029] Scale areas 15 are provided on both sides of the tube groove 14 , and the punching body 2 is preferably moved on the scale area 15 to facilitate scale comparison.

[0030] The fixing body 4 is a spring clamp and is mounted on the base 1 for clamping the hose placed in the pipe groove 14 .

[0031] like Figure 3The punching body 2 is provided with a mounting portion 21 and a tool hole 22. The punching body 2 is in the shape of a Chinese character "F", with mounting portions 21 formed on both sides and three tool holes 22 provided on the top for the punching tool to punch holes in the hose. The punching body 2 may be provided with a slider portion that cooperates with the position adjustment groove 11, or it may not be provided. After adjusting the punching body 2, screw in the screw to fix it.

[0032] The punching body 2 is made of acrylic material and is formed by splicing or integrally forming five acrylic plates. AB glue is used for bonding at the splicing points. The position of the tool hole 22 can be designed according to the actual needs. The acrylic material is preferably a highly transparent material so that the scale on the scale area 15 can be clearly seen before punching, making the punching position more accurate.

[0033] Optionally, the diameter of the mandrel 3 is greater than or equal to the inner diameter of the hose 5 to be perforated.

[0034] In this embodiment, the core rod 3 is a regular hexagonal core rod. The regular hexagonal design makes it easier to insert into the hose 5. Since the diagonal of the regular hexagonal core rod 3 is slightly larger than the inner diameter of the hose 5, it can prevent the hose 5 from slipping and deflecting. When the hose 5 is a reducer, the effect is better.

[0035] The regular hexagonal core rod 3 is made of POM material, which has a certain hardness and toughness, so that it can protect the punching tool during punching and reduce tool wear.

[0036] During drilling, the hose 5 is secured to the base 1 via the regular hexagonal mandrel 3, the tube groove 14, and the fixing body 4. The punching body 2 adjusts the drilling position according to the scale, and the tool moves downward through the tool hole 22 to drill the hole. Due to the regular hexagonal mandrel 3 and the spring clamp, the hose 5 does not deflect or tilt during drilling. The device has a simple overall structure, is easy to install and use, and is low in overall cost, making it highly cost-effective.

[0037] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations and modifications may be made to the embodiments of the present invention without departing from the principles described.
