Description

Technical Field

[0001] This utility model relates to an automatic pipe cutting machine. Background Technology

[0002] A pipe cutter is a common tool, also known as a pipe cutter or pipe slasher. It is widely used in construction, machining, and pipe installation, and is a crucial hand tool in both household and industrial hardware. The general workflow for a manual pipe cutter is as follows: First, ensure the work area is safe and clean, avoiding clutter and obstructions. Second, check the sharpness and stability of the cutter's blade. If the blade is worn or loose, replace or adjust it promptly. Finally, place the pipe to be cut on the cutting table and secure it with clamps to prevent movement or slippage. Adjust the cutting size scale on the pipe cutter to the required pipe dimensions, ensuring precision and accuracy. Secure the cutter to the pipe, ensuring the cutting blade is perpendicular, and use screws or clamps for fixation. Press the cutting blade firmly against the pipe and rotate it with appropriate force to cut. During cutting, maintain a stable force and speed, avoiding excessive speed or slowness to prevent affecting the cutting effect. After cutting, check the cut surface for smoothness and whether it meets the expected dimensions. If necessary, a file or grinding tool can be used to refine the cut surface. However, for a long time, purely manual pipe cutters have suffered from poor efficiency and cut quality, and there are a series of safety hazards during operation: When using a pipe cutter, pay attention to safe operation. Avoid touching the blade with your fingers to prevent cutting injuries. Also, remain focused during cutting operations to avoid distraction or impatience that could lead to accidents. After cutting, promptly process the cut surface to prevent sharp edges from causing injury. When cutting pipes, control the cutting speed appropriately according to the pipe material and size. Excessive cutting speed may damage the blade or reduce the quality of the cut surface, while excessively slow cutting speeds waste time and effort. Utility Model Content

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0024] An automatic pipe cutting machine includes a support assembly 4; a guide assembly 2 is mounted on the support assembly 4, a drive assembly is movably mounted on one end of the guide assembly 2, and a cutting assembly 1 is fixedly mounted on the other end;

[0025] The drive assembly is equipped with a rotary motor 301 and a walking motor 302. A chuck 306 is installed on the rotating shaft of the rotary motor 301 to fix one end of the steel pipe 5. The walking motor 302 drives the drive assembly to move on the guide assembly 2.

[0026] The cutting assembly 1 includes a limiter 105 and a circular blade 102. The limiter 105 is installed at the end of the guide assembly 2 and in the traveling direction of the steel pipe 5. The circular blade 102 is installed on the push rod of the cutting cylinder 101 and is perpendicular to the steel pipe 5. The cutting cylinder 101 is vertically installed on the steel pipe 5.

[0027] The rotating motor 301 is mounted on the traveling trolley 304. Guide wheels 305 are installed at the lower ends of the four corners of the traveling trolley 304. The four guide wheels 305 are respectively locked in pairs on both sides of the guide assembly 2. The traveling motor 302 is mounted on the traveling motor mounting plate 303. The traveling motor mounting plate 303 is vertically fixed to the edge of the traveling trolley 304. A traveling wheel 309 is mounted on the rotating shaft of the traveling motor 302. The traveling wheel 309 presses against the guide assembly 2.

[0028] The lower end of the guide wheel 305 is also equipped with an anti-tipping device 308. The anti-tipping device 308 is a square frame that is vertically fitted onto the bracket assembly 4. The upper end of the anti-tipping device 308 is connected to the lower end of the guide wheel 305.

[0029] The circular blade 102 is connected to the cutting cylinder 101 via the blade mounting cylinder 115. The blade mounting cylinder 115 is fixed on the push rod of the cutting cylinder 101, and the circular blade 102 is mounted inside the blade mounting cylinder 115 via a rotating shaft.

[0030] The cutting cylinder 101 is mounted on the guide assembly 2 via the cutting bracket 104. The cutting bracket 104 spans vertically across the guide assembly 2. The cutting cylinder 101 is vertically fixed to the top of the cutting bracket 104. Two support rollers 103 parallel to the steel pipe 5 are also installed at the bottom of the cutting bracket 104. There is a gap of no more than 2cm between the two support rollers 103. The rotating shaft of the circular blade 102 is located at the center of the gap between the two support rollers 103. The circular blade 102 extends out of one end of the two support rollers 103.

[0031] The cutting bracket 104 is also equipped with a normally closed contact switch 117 on one edge opposite to the drive assembly. One end of the blade mounting cylinder 115 extends out of the cutting bracket 104 and is equipped with a contact piece 116. The lower end face of the contact piece 116 contacts the rocker arm of the normally closed contact switch 117.

[0032] The limiter 105 is hinged to the limiter shaft 106, which is vertically mounted on the guide assembly 2. A limiter switch bracket 108 is also mounted on the guide assembly 2 on the side of the limiter 105 away from the cutting assembly 1. A normally open contact switch 107 and a return spring push rod 109 are mounted on the limiter switch bracket 108. The spring of the normally open contact switch 107 and the return spring push rod 109 are both in contact with the limiter 105. When the travel motor 302 pushes the steel pipe 5 to the designated position, the end of the steel pipe 5 contacts the limiter plate 118 on the limiter and pushes the limiter... When the limit switch rotates horizontally, it simultaneously presses the spring of the normally open contact switch 107 and the return spring push rod. The contacts of the normally open contact switch are pressed by the spring and switched to the closed state, triggering the cylinder to press down the cutter to cut the steel pipe. The limit switch bracket 108 is also equipped with a limit switch baffle 110 on its end face relative to the limit switch 105. The limit switch baffle 110 blocks the rotation direction of the limit switch 105. When the limit switch triggers the normally open contact switch, it contacts the limit switch baffle 110 to prevent the limit switch from rotating excessively, which would cause the length of the cut steel pipe to be inconsistent and damage the normally open contact switch.

[0033] The limit switch bracket 108 is mounted on the guide assembly 2 via the mounting sleeve 111. The mounting sleeve 111 and the guide assembly 2 have pin holes machined on their sides, and a positioning pin 112 is installed in the pin holes. A travel limit plate 201 is also mounted on the guide assembly 2, and the travel limit plate 201 is installed between the cutting assembly 1 and the driving assembly.

[0034] The limiter 105 is provided with a limit plate 118 on its end face relative to the cutting assembly 1. The limit plate 118 is mounted on the limiter 105 through a limit bearing seat 119 and is directly opposite the steel pipe 5.

[0035] The support assembly 4 includes two support beams 401, with both ends of the two support beams 401 vertically connected to the middle of a column 403. Several connecting rods 402 are evenly connected between the two support beams 401. The top and bottom of the column 403 are connected by a crossbeam 404, and casters 405 are installed at both ends of the lower end face of the crossbeam 404.

[0036] The guide assembly 2 includes two conduits 202, which are fixed in parallel on the top of the support assembly 4. A steel pipe guide sleeve 203 is installed on one end of the guide assembly 2 adjacent to the cutting assembly 1 through the guide sleeve bracket 204. The steel pipe guide sleeve 203 is co-centered with the steel pipe 5.

[0037] like Figure 3The diagram illustrates the control principle of this application. The air compressor is turned on via a start switch to fill the pressure. The steel pipe to be cut is placed on the bracket and clamped by a chuck. Pressing the forward / reverse switch activates the geared motor, pulling the steel pipe to the far end of the bracket. Releasing the forward / reverse switch stops the geared motor. The limit switch baffle is adjusted to the set position. The main motor switch is activated, starting the main motor and rotating the steel pipe. Activating the automatic switch closes the normally closed contact switch, causing the geared motor to run and push the rotating steel pipe forward. When the steel pipe reaches the limit switch's set position, it presses against the baffle, simultaneously compressing the normally closed and normally open contact switch springs. The normally closed contact switch opens, stopping the geared motor. Stepping; when the normally open contact switch is turned on, the coil of the single-control two-position five-way solenoid valve is energized, compressed air enters the rear chamber of the cylinder, and the cylinder piston rod presses down on the cutter, causing the blade to contact the steel pipe body, and cutting begins; once the steel pipe is cut off, the short pipe falls off, the limit switch baffle is released, and the normally closed contact switch and the normally open contact switch spring simultaneously pop open; the normally open contact switch is turned off, the solenoid valve core automatically returns to its original position, compressed air enters the front chamber of the cylinder, and the cylinder piston rod retracts, driving the cutter upward back to its initial position; the normally closed contact switch is turned on, the geared motor runs, and pushes the rotating steel pipe stepping forward... this cycle repeats until the entire steel pipe is cut, and then the main motor switch and automatic switch are turned off.
