Description

Technical Field

[0001] This utility model relates to the field of semi-automatic pipe cutting machine technology, specifically a small stainless steel round pipe cutting machine. Background Technology

[0002] The small stainless steel round pipe cutting machine adopts a semi-automatic mode for pipe cutting. The existing small stainless steel round pipe cutting machine only has one station for placing round pipes. Only one round pipe can be placed at a time. When the rocker arm is manually pressed down to drive the machine head and grinding wheel to swing downward, only one round pipe can be cut at a time, resulting in low cutting efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a small stainless steel round pipe cutting machine, which solves the problem that existing small stainless steel round pipe cutting machines can only cut one round pipe at a time, resulting in low efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A small stainless steel round tube cutting machine includes a machine base, a hinged seat fixed on the machine base, a machine head hinged on the hinged seat, and a grinding wheel mounted on the machine head. The machine base is provided with two sets of rolling support frames for supporting two round tubes. Rolling bearings mounted on the two sets of rolling support frames support the two round tubes respectively. The grinding wheel can contact the two round tubes simultaneously.

[0006] A fixed frame is fixed on one side of the machine base. A stop frame supporting the end of the round tube is slidably connected to the fixed frame. An adjusting bolt that is rotatably connected to the side of the stop frame is installed on the fixed frame with a transverse thread. A movable plate that is inclined and supported below the round tube is movably hinged to the stop frame. A support spring is provided between the movable plate and the stop frame.

[0007] Preferably, each of the rolling support frames is equipped with multiple rolling bearings, and each group of rolling support frames includes at least four rolling support frames that are symmetrical in front and behind and in the left and right.

[0008] Preferably, the stop frame is L-shaped, the vertical part of the stop frame is supported on the end of the circular tube, and the movable plate and support spring are installed on the horizontal part of the stop frame.

[0009] Preferably, the bottom of the stop frame is provided with two transverse guide bars symmetrically arranged front and back, and the fixed frame is provided with guide grooves that are slidably connected to the guide bars.

[0010] Preferably, the adjusting bolt is a hand-tightened Torx bolt.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) This utility model sets a set of rolling support frames and rolling bearings on the front and back sides of the grinding wheel to simultaneously support two round tubes. After placing the two round tubes, the grinding wheel flips down to contact the two round tubes at the same time, presses down to position the round tubes and cuts them synchronously, thus achieving the effect of cutting two round tubes in one operation. This greatly improves efficiency on the basis of existing technology and solves the problem that existing small stainless steel round tube cutting machines can only cut one round tube at a time, resulting in low efficiency.

[0013] (2) The present invention provides a stop frame that can be moved laterally and adjusted on the side of the machine to position the right end of the round tube. Before cutting, the position is adjusted according to the required length. After cutting, the tube can be directly positioned and cut, which improves the accuracy, simplifies the operation steps, and also improves the efficiency. In addition, a movable plate supported by a support spring is provided below the stop frame. After the round tube loses the pressure of the grinding wheel after cutting, the support spring and the movable plate can support the right end of the cut round tube to tilt up, which makes it convenient for manual removal of the round tube for unloading. It is easy to use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4As shown, this utility model provides a technical solution: a small stainless steel round pipe cutting machine, including a machine base 1, a hinge seat 2 fixed on the machine base 1, a machine head 3 hinged on the hinge seat 2, and a grinding wheel 4 installed on the machine head 3.

[0021] The machine base 1 is equipped with two sets of rolling support frames 6 for supporting two round tubes 5. The rolling bearings 7 installed on the two sets of rolling support frames 6 are respectively supported below the two round tubes 5. The grinding wheel 4 can contact the two round tubes 5 at the same time. Each rolling support frame 6 is equipped with multiple rolling bearings 7. Each set of rolling support frames 6 includes at least four rolling support frames 6 that are symmetrical in front and behind and symmetrical in left and right.

[0022] A fixed frame 8 is fixed on one side of the machine base 1. A stop frame 9 supported on the end of the round tube 5 is slidably connected to the fixed frame 8. Two horizontal guide bars 13 are symmetrically arranged at the bottom of the stop frame 9. A guide groove 14 is provided on the fixed frame 8 that is slidably connected to the guide bars 13.

[0023] The stop frame 9 is L-shaped. The vertical part of the stop frame 9 is supported on the end of the round tube 5. The fixing frame 8 is horizontally threaded with an adjusting bolt 10 that is rotatably connected to the side of the stop frame 9. The adjusting bolt 10 is a hand-tightening plum bolt. The stop frame 9 is movably hinged with a movable plate 11 that is inclined and supported below the round tube 5. A support spring 12 is provided between the movable plate 11 and the stop frame 9. The movable plate 11 and the support spring 12 are installed on the horizontal part of the stop frame 9.

[0024] Working principle:

[0025] According to the required cutting length of the round tube 5, turn the adjusting bolt 10 to drive the stop frame 9 to move laterally. Adjust the lateral distance between the left side of the stop frame 9 and the grinding wheel 4 to meet the cutting length. Place the two round tubes 5 laterally from left to right on the rolling bearings 7 on the two sets of rolling support frames 6. Press down on the round tubes 5 to keep them horizontal. Move the rocker arm to make the machine head 3 rotate downward with the grinding wheel 4 so that it can contact the two round tubes 5 at the same time. Press down synchronously for positioning. The machine head 3 drives the grinding wheel 4 to rotate and cut the two round tubes 5 synchronously. After the cutting is completed, when the round tube 5 loses the pressure of the grinding wheel 4, the support spring 12 and the movable plate 11 can support the right end of the cut round tube 5 to tilt up, making it convenient for manual removal of the round tube 5 for unloading.
