Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe processing, in particular to a steel pipe cutting machine. Background Art

[0002] Steel pipe cutting machine is an electric device that can cut and cut various building steel materials such as stainless steel, bearing steel, structural steel, aluminum and aluminum alloy. The commonly used steel pipe cutting machines on the market can be divided into planetary cutting machines, hydraulic cutting machines, external card cutting machines and pneumatic cutting machines according to their working mode.

[0003] Its working principle is mainly to cut the steel pipe by a high-speed rotating cutting tool. The feeding mechanism feeds the steel pipe into the cutting mechanism, and the cutting mechanism cuts at the position determined by the positioning mechanism.

[0004] When using a steel pipe cutting machine, you need to adjust the cutting machine angle to adapt to the cutting of various pipes, select the appropriate cutting blade, and adjust it according to the required cutting depth.

[0005] The current steel pipe cutting machine needs to clamp and position the steel pipe before cutting it. However, there may be debris such as iron filings on the outside of the steel pipe. If it is not removed and clamped directly, it will cause indentations on the surface of the steel pipe and affect the surface quality of the steel pipe. Utility Model Content

[0006] The purpose of the utility model is to provide a steel pipe cutting machine to solve the above-mentioned technical problems, so as to prevent crushing and ensure the surface quality of the steel pipe.

[0007] In view of this, the utility model provides a steel pipe cutting machine, including a machine base, on which are arranged:

[0008] A guide assembly, which is used to assist the steel pipe in maintaining straight transmission;

[0009] A clamping assembly, wherein the clamping assembly and the guide assembly are in the same straight line and are used to clamp and fix the steel pipe;

[0010] A cutting assembly, wherein the cutting assembly is used for cutting the steel pipe;

[0011] The steel pipe cutting machine also includes a cleaning component, which is arranged before the clamping component and is used for cleaning the outer periphery of the steel pipe before the steel pipe is clamped.

[0012] In the present technical solution, the outer periphery of the steel pipe is cleaned in advance by the cleaning assembly before the clamping assembly, so that there is no large debris or iron filings on the outer periphery of the steel pipe when it is clamped by the clamping assembly, thereby preventing crushing and ensuring the quality of the steel pipe surface.

[0013] Furthermore, the cleaning component comprises:

[0014] A cleaning frame, wherein the cleaning frame is provided with a connecting hole and a stage;

[0015] The cleaning brush comprises a large diameter section and a small diameter section which are connected to each other, wherein the small diameter section matches the connecting hole, and the large diameter section matches the stage. A cleaning hole is also provided in the center of the cleaning brush, and a cleaning brush is arranged in the cleaning hole to clean the steel pipe passing through the cleaning hole.

[0016] In this technical solution, the small diameter section of the cleaning brush is inserted into the connecting hole, and the large diameter section is inserted into the stage. The matching steel pipe will pass through the cleaning hole of the cleaning brush during the continuous transmission to the clamping assembly. Because the steel pipe is continuously moving, the debris on the steel pipe will be blocked by the cleaning brush and cannot continue to be transmitted forward with the steel pipe.

[0017] Furthermore, the stage is located on a side of the connecting hole away from the cutting assembly.

[0018] In this technical solution, the stage is located on the side of the connecting hole away from the cutting assembly, and the steel pipe is transmitted in the direction of the cutting assembly. Therefore, the movement of the steel pipe will give the cleaning brush a driving force in the direction of the cutting assembly, so that the cleaning brush can always be against the stage in the direction of the connecting hole and will not leave the cleaning frame and fall.

[0019] Furthermore, a magnet is arranged on the step surface of the stage, and a magnet is also arranged on the end surface of the large diameter section of the cleaning brush facing the small diameter section.

[0020] In the technical solution, the cleaning brush can be magnetically attracted to the cleaning frame by magnets at two positions, thereby further fixing the cleaning brush.

[0021] Furthermore, the clamping assembly comprises:

[0022] A fixed plate, wherein a first cutter groove is formed on the fixed plate, the first cutter groove and the grinding wheel cutter of the cutting assembly are on the same vertical line, and a first clamping block and a second clamping block are fixedly connected to both sides of the first cutter groove respectively;

[0023] The clamping plate is slidably arranged on the machine base and connected to the piston rod of the clamping cylinder. A second tool-allowing groove is provided on the clamping plate. The second tool-allowing groove and the grinding wheel cutter of the cutting assembly are on the same vertical line. A third clamping block and a fourth clamping block are fixedly connected to both sides of the second tool-allowing groove respectively. The clamping cylinder can push the clamping plate towards or away from the fixed plate.

[0024] Furthermore, the machine base is arranged on the base frame, and the machine base and the base frame are connected via a sliding assembly, and the sliding assembly can make the machine base slide relative to the base frame to unload and drive the steel pipe to feed.

[0025] Furthermore, the sliding assembly includes:

[0026] A guide shaft, wherein the guide shaft is set on the base frame;

[0027] A fixed sleeve, wherein the fixed sleeve is fixedly arranged at the bottom of the machine base, the fixed sleeve is arranged outside the guide shaft and is slidably arranged on the guide shaft with the machine base;

[0028] A driving motor, wherein the driving motor is fixedly arranged on the base frame;

[0029] A transmission belt, which is tensioned on the base frame and connected to the output end of the drive motor;

[0030] The connecting block is fixedly arranged at the bottom of the machine base, and the connecting block is sleeved on the transmission belt and fixedly connected with the transmission belt.

[0031] In the present technical solution, when the grinding wheel cutter of the cutting assembly has finished cutting the steel pipe downwards, the driving motor is started to drive the transmission belt to drive the machine base to slide along the direction of the guide shaft. During this process, the steel pipe is cut into two ends, and the cut section is clamped by the second clamping block and the fourth clamping block and moved to the unloading position, and the remaining steel pipes are clamped by the first clamping block and the third clamping block for moving feeding. When the machine base moves to the preset position, the driving motor is turned off, and then the piston rod of the clamping cylinder is driven to move the clamping plate away from the fixed plate. In this way, the cut steel pipe falls down to complete the unloading, while the steel pipe at the other end remains fixed due to the action of the guide assembly. Then the machine base is reset under the action of the sliding assembly, and the clamping assembly re-clamps the steel pipe to prepare for the next cutting.

[0032] Furthermore, a chip blowing structure is also provided on the machine base, and the chip blowing structure can blow away the debris on the clamping block when the clamping assembly is released.

[0033] Furthermore, the chip blowing structure includes four air blowing pipes arranged on the machine base, and each air blowing pipe is respectively aligned with a clamping block.

[0034] The beneficial effects of the utility model are:

[0035] 1. Before the clamping assembly, the outer periphery of the steel pipe is cleaned in advance by the cleaning assembly, so that there is no large debris or iron filings on the outer periphery of the steel pipe when it is clamped by the clamping assembly, thereby preventing crushing and ensuring the quality of the steel pipe surface.

[0036] 2. The stage is located on the side of the connecting hole away from the cutting assembly, and the steel pipe is transmitted in the direction of the cutting assembly. Therefore, the movement of the steel pipe will give the cleaning brush a driving force in the direction of the cutting assembly, so that the cleaning brush can always be against the stage in the direction of the connecting hole and will not leave the cleaning frame and fall. The structure is simple and the stability is strong.

[0037] 3. Magnets at two positions can make the cleaning brush magnetically attracted to the cleaning rack, further fixing the cleaning brush. BRIEF DESCRIPTION OF THE DRAWINGS
