DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0029] like Figure 1 As shown, a long tube blanking rack for a laser tube cutting machine includes a support rod 1, at least two support units 2 for supporting the tubes and spaced apart in sequence along the length direction of the support rod. The support rod is arranged along the length direction of the long tube. In this embodiment, there are three support units. Each support unit is provided with at least one clamping jacket 3, which is slidably connected to the support rod and provided with a locking piece. By adjusting the position of each support unit on the support rod, the distance between each adjacent two support units is changed, so that the overall length of the blanking rack is adapted to the length of the tube being blanked. Figure 4 and Figure 5As shown, the clamping jacket is an annular structure with an opening 301 on one side and is mounted on the support rod, forming an overall C-shaped structure. A locking member is located at the opening of the clamping jacket. The locking member is a locking screw 4, which is threadedly connected to both sides of the clamping jacket opening. The clamping jacket is made of metal and has a certain support strength and elasticity. When the support unit is moved to the preset position, the width of the opening is narrowed by rotating the locking screw, thereby locking the clamping jacket and the support rod, thereby fixing the support unit. If the pipe being cut changes, the position of the support unit can be adjusted again and the clamping jacket can be locked, achieving the use requirements of pipes of different lengths. To strengthen the connection between the support unit and the support rod, each support unit is provided with a through-hole (not shown) that matches the clamping sleeve. Clamping sleeves are installed at both ends of the through-hole. Specifically, the support rod passes through the support frame of each support unit, and clamping sleeves are attached to both sides of the connection with the support rod using bolts / screws. The two clamping sleeves are coaxially arranged, and the support rod is simultaneously locked and secured by both clamping sleeves. In this embodiment, there are three groups of support rods, and each support rod has six clamping sleeves at its connection to each support frame, providing a stable connection structure.

[0030] like Figure 2 and Figure 3 As shown, the support unit includes a support frame 201 and a support assembly. The upper end of the support frame is provided with an inclined blanking plate 207 and a horizontally arranged receiving plate 208. One end of the receiving plate is connected to the lower end of the blanking plate. The pipe material first falls on the blanking plate and then rolls down from the blanking plate to the receiving plate. A stopper 209 is provided on the top of the receiving plate away from the blanking plate. The stopper blocks the pipe material to prevent it from rolling off the receiving plate. The support assembly is located on one side of the blanking plate and includes a lifting frame 202 and a lifting cylinder 203. The lower end of the lifting frame is connected to the lifting cylinder, and the upper end is provided with a pipe support 204. The lifting cylinder drives the lifting frame and the pipe support to move up and down. The lower end of the lifting frame is provided with a lifting rod 2010. The lifting rod is slidably connected to a guide cylinder 2011 provided on the support frame to ensure the stability of the lifting frame.

[0031] In order to meet the requirements of different diameters and types of pipes (round pipes, square pipes, etc.), the pipe support is a variable diameter wheel, combined with Figure 2 and Figure 3As shown, the reducing wheel is provided with a gradually varying width reducing groove 20401 along its circumference. The reducing wheel is rotatably connected to the lifting frame, with a reducing wheel positioning assembly disposed between the two. By rotating the reducing wheel, the width of the reducing groove at its top can be adjusted to match the corresponding unloaded pipe. After adjustment, the reducing wheel positioning assembly is used to lock and secure it. The reducing wheel positioning assembly includes a positioning rod 205 provided on the lifting frame, and a plurality of positioning holes 206 provided at the end of the reducing wheel and distributed in a circumferential array. The positioning rod is mated with the plurality of positioning holes, which are evenly spaced. The positioning rod is threadedly connected to the lifting frame. By rotating the positioning rod, the end of the positioning rod can be inserted into the corresponding positioning hole to achieve locking and securing. The outer diameter of the positioning rod matches the diameter of the positioning hole.

[0032] The method of using this utility model is as follows:

[0033] like Figure 1 As shown, the present invention is used to cooperate with a laser tube cutting machine to cut long tubes and is installed at the long tube cutting position of the laser tube cutting machine. First, according to the cutting length, adjust the position of several support units 2 on the support rod 1, thereby changing the distance between each adjacent support unit 2, and then lock and hold the jacket 3 to fix the position of the support unit 2. Then, according to the type and specification of the actual tube to be cut, adjust the width of the reducing groove at the top of the reducing wheel 204, and lock and fix it with the positioning rod 205. When in use, the height of the reducing wheel 204 is higher than the blanking plate 207. After cutting, the long tube is supported in the reducing groove 20401 of each reducing wheel. Then, the lifting cylinder 203 of each support unit 2 works synchronously, driving the tube to move downward and fall onto the blanking plate 207. The tube rolls down from the blanking plate 207 to the receiving plate 208 until it contacts the stopper 209, thus completing the blanking work.

[0034] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
