DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 6 As shown, a metal product cutting tool holder includes a tool holder 1, a supporting mechanism, an auxiliary mechanism and a cutting mechanism; a through hole 11 is opened on the tool holder 1, a metal product 9 is placed in the through hole 11, and the supporting mechanism is arranged on one side of the tool holder 1 and supports the metal product 9; an auxiliary mechanism is arranged on the side wall of the tool holder 1, and the auxiliary mechanism is arranged on both sides of the through hole 11; the auxiliary mechanism includes a cylinder 2, a buffer seat 21, a first spring 23, a buffer block 22 and a clamping wheel 24; the output end of the cylinder 2 is connected to the buffer seat 21; the buffer block 22 is arranged inside the buffer seat 21; the two ends of the first spring 23 are respectively connected to the buffer seat 21 and the buffer block 22; one end of the clamping wheel 24 is connected to the buffer block 22, and the other end is connected to the metal product 9; the clamping wheel 24 is pushed to approach the two sides of the metal product 9 by the cylinder 2, so as to maintain the stability of the two sides of the metal product 9 during the cutting process and improve the cutting quality.

[0023] A pre-tightening groove 3 is provided on the top of the buffer seat 21; the pre-tightening groove 3 is divided into two sections, and the groove opening of the pre-tightening groove 3 near one end of the clamping wheel 24 is smaller; a pre-tightening block 4 is provided on the top of the buffer block 22, and the pre-tightening block 4 is slidably installed in the pre-tightening groove 3; a telescopic block 41 and a second spring 42 are provided in the pre-tightening block 4; the two ends of the second spring 42 are respectively connected to the telescopic block 41; the telescopic direction of the telescopic block 41 is perpendicular to the moving direction of the buffer block 22 on the horizontal plane; when the cylinder 2 pushes the clamping wheel 24 to approach the metal product 9, the extrusion force causes the buffer block 22 to move into the buffer seat 21, and during the movement, the pre-tightening block 4 moves accordingly, and when the pre-tightening block 4 moves from the small pre-tightening groove 3 to the large pre-tightening groove 3, the telescopic block 41 extends out through the second spring 42 to clamp the buffer block 22, thereby adjusting the pre-tightening force of the first spring 23 and realizing the pre-tightening function, which can reduce the vibration and impact that may be generated during the cutting process and improve the cutting quality and efficiency.

[0024] like Figure 1 , Figure 2 and Figure 6 As shown, the supporting mechanism includes a supporting seat 5, a mounting seat 51 and a supporting roller 52; the supporting seat 5 is fixedly arranged on the side wall of the tool holder 1; the mounting seat 51 is arranged at the front and rear ends of the top of the supporting seat 5; the supporting roller 52 is rotatably arranged on the mounting seats 51 at the front and rear ends; two supporting rollers 52 are installed on the supporting seat 5; the supporting rollers 52 are used to support the metal product 9.

[0025] The support mechanism is provided to provide stable support for the metal product 9 during the cutting process. The combination of the support seat 5, the mounting seat 51 and the support roller 52 can ensure that the metal product 9 will not shake or move during the cutting process, thereby improving the accuracy and quality of the cutting. In addition, since the support rollers 52 are rotatable, they can also reduce the friction between them and the metal product 9, making the cutting process smoother.

[0026] like Figure 1 and Figure 2 As shown, an adjustment mechanism is provided at the bottom of the support seat 5, and the adjustment mechanism includes a positioning block 6, an adjustment shaft 61 and an adjustment handle 62; the positioning block 6 is provided on the side wall of the tool holder 1 and is located below the support seat 5; one end of the adjustment shaft 61 is connected to the bottom of the support seat 5, and the other end passes through the positioning block 6 and is connected to the adjustment handle; the adjustment shaft 61 and the positioning block 6 are threadedly connected.

[0027] By providing the adjustment mechanism, the height of the support base 5 can be conveniently adjusted to adapt to metal products 9 of different heights or sizes, thereby improving the stability and accuracy of the cutting process.

[0028] like Figure 2 and Figure 6As shown, the support mechanism is disposed on both sides of the tool holder 1; the bottom of the support seats 5 on both sides are provided with adjustment mechanisms; and a connecting block 7 is disposed between the support seats 5 on both sides.

[0029] By arranging support mechanisms on both sides of the tool holder 1, and the bottom of each support seat 5 is equipped with an adjustment mechanism, the support mechanism is both stable and flexible. At the same time, the support seats 5 on both sides are connected to each other through the connecting block 7, which enhances the stability and rigidity of the entire support mechanism. It ensures that the metal product 9 is stably and accurately supported during the cutting process, thereby improving the cutting quality and efficiency.

[0030] like Figure 1 As shown, the cutting mechanism includes an electric slide 8, a rotating motor 81 and a cutter 82; the electric slide 8 is fixedly arranged on the side wall of the tool holder 1; the rotating motor 81 is installed on the electric slide 8; and the cutter 82 is connected to the output end of the rotating motor 81.

[0031] The combination of the electric slide 8 and the rotary motor 81 also provides greater flexibility and adaptability, and can adapt to different cutting environments and requirements.

[0032] The working principle of the utility model is as follows: when cutting the metal product 9 in the tube, the metal product 9 is placed in the through hole 11, and the height of the support seat 5 can be adjusted by rotating the adjusting handle 62. When the supporting roller 52 contacts the metal product 9, the adjusting handle 62 is stopped from rotating, and the two ends of the metal product 9 are supported by the supporting roller 52. Then the clamping wheel 24 is pushed to move toward the metal product 9 by the cylinder 2. When the clamping wheel 24 contacts the metal product 9, the extrusion force acts on the buffer block 22, so that the buffer block 22 moves into the buffer seat 21 through the first spring 23, and the pre-tightening block 4 moves in the pre-tightening groove 3. When the pre-tightening block 4 moves from the pre-tightening groove 3 with a small size to the pre-tightening groove 3 with a large size, the telescopic block 41 extends through the second spring 42 to clamp the buffer. At this time, the cylinder 2 is stopped from outputting, and the clamping wheels 24 on both sides generate pre-tightening force on the first spring 23 while contacting the metal product 9. The electric slide 8 drives the rotating motor 81 and the tool 82 to move to the top of the metal product 9 along the set path. The rotary motor 81 drives the cutter 82 to rotate at a high speed, and the cutter 82 contacts and cuts the metal product 9. By precisely controlling the moving speed of the electric slide 8 and the rotation speed of the rotary motor 81, the metal product 9 can be accurately and efficiently cut, and the vibration and impact generated during the cutting process can be reduced, thereby improving the cutting quality and efficiency.

[0033] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
