Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an online automated cutting device for pipe fittings. Background Technology

[0002] Pipe fittings are a collective term for components in a piping system used for connection, control, direction change, flow distribution, sealing, and support. Plastic pipe fittings are generally manufactured through injection molding. After injection molding, the fittings need to be cut to allow for the selection of different lengths.

[0003] Existing equipment for cutting plastic pipes, such as the automatic pipe cutting device and method disclosed in Chinese patent literature [Patent No.: 202110528587.3; Application Publication No.: CN113245612B], includes a worktable; a cutting unit located in the middle of the worktable to perform pipe cutting; a clamp located on the top surface of the middle of the worktable, in front of the cutting unit, to clamp the pipe to be cut; a feeding unit located on the top surface of the worktable on one side of the clamp, which feeds the pipe to be cut in the direction toward the clamp; and a feeding unit located on the top surface of the worktable on the other side of the clamp, which feeds the cut pipe in the direction away from the clamp.

[0004] This type of automatic pipe cutting equipment places the pipe to be cut in the feeding unit, starts feeding, and transports the pipe to the clamp for automatic clamping. The cutting unit then completes the cutting action, and the cut pipe is fed back by the feeding unit. However, in this type of automatic pipe cutting equipment, the pipe stops being transported and moved while the clamp is automatically clamping the pipe and the cutting unit is cutting the pipe. The pipe will only continue to be transported and moved after the cut is completed and the clamp is released. That is, there is a pause in the middle of the cutting process, and the action is not continuous. Moreover, the pipe must be injection molded and removed before it can be cut by this type of automatic pipe cutting equipment, resulting in low processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an online automated pipe cutting device, which solves the technical problem of how to improve the cutting efficiency of pipes.

[0006] The objective of this utility model can be achieved through the following technical solution: an online automated pipe cutting device, comprising a frame, characterized in that it further comprises a sliding plate disposed on the frame and capable of reciprocating along the X-axis direction, a gantry frame fixedly connected to the sliding plate, a circular blade rotatable and capable of reciprocating along the Y-axis and Z-axis directions disposed on the gantry frame, a plurality of pairs of first drive sources fixedly connected to the bottom of the sliding plate, a plurality of elongated clamping plates arranged parallel to each other at intervals above the sliding plate and arranged along the Y-axis direction, the output shaft of the first drive source passing through the sliding plate and fixedly connected to the end of the clamping plate, the clamping plate being capable of pressing the pipe onto the sliding plate.

[0007] This cutting equipment is directly installed at the discharge port of the injection molding machine. The extruded pipe from the injection molding machine moves along the X-axis into this cutting equipment, positioning the pipe between the sliding plate and the clamping plate. The moving speed of the sliding plate is controlled to be the same as the moving speed of the pipe, so that the sliding plate and the pipe move synchronously along the X-axis. This causes the gantry, circular blade, and clamping plate mounted on the sliding plate to move synchronously along the X-axis with the pipe. The output shaft of the first drive source retracts, causing the clamping plate to press the pipe firmly against the sliding plate. Then, the circular blade moves along the Y-axis... The device moves along the Z-axis to cut the pipe. After cutting, the circular blade rises along the Z-axis and moves back to its original position along the Y-axis. Simultaneously, the output shaft of the first drive source extends, causing the clamping plate to release the pipe. The sliding plate moves back along the X-axis, pushing the cut pipe from the injection molding machine into the unloading frame. After the sliding plate returns to its original position, the output shaft of the first drive source retracts, causing the clamping plate to press the pipe against the sliding plate. The circular blade then cuts the pipe. This cycle repeats to cut multiple pipes. The sliding plate of this cutting device moves synchronously with the pipe, allowing for online pipe cutting without stopping the machine, thus improving cutting efficiency.

[0008] In the aforementioned online automated pipe cutting equipment, the sliding plate has several guide holes, and a guide rod is fixedly connected to the end of the clamping plate, passing through the guide holes. Both the guide rod and the guide holes serve a guiding function, causing the clamping plate to move in the opposite direction as set, allowing the clamping plate to better press the pipe onto the sliding plate, achieving pipe positioning, improving the stability of the cutting equipment, reducing the failure rate, and thus increasing the pipe cutting efficiency.

[0009] In the aforementioned online automated pipe cutting device, the sliding plate has a long, narrow slit along the Y-axis, located directly below the circular blade, which can pass through the slit. This slit design ensures the circular blade can cut the pipe, reducing the failure rate and thus improving the pipe cutting efficiency.

[0010] In the aforementioned online automated pipe cutting equipment, there are two clamping plates located on either side of the blade slit. This structure allows the clamping plates to better hold the pipe in place, improving the stability of the cutting equipment.

[0011] In the aforementioned online automated pipe cutting equipment, a second drive source and a lead screw and slider assembly are fixedly connected to the frame. The second drive source drives the lead screw of the lead screw and slider assembly to rotate, and the slider of the lead screw and slider assembly is fixedly connected to the sliding plate. The lead screw and slider assembly achieves synchronous movement between the sliding plate and the pipe, resulting in a simple structure.

[0012] In the above-mentioned online automated pipe cutting equipment, the first driving source is a driving cylinder or a driving hydraulic cylinder, and the second driving source is a driving motor.

[0013] In the aforementioned online automated pipe cutting equipment, a support roller and a pressure roller are provided at one end of the frame. The pressure roller is located directly above the support roller. Both the support roller and the pressure roller are arranged along the Y-axis. Adjustment frames are provided at both ends of the pressure roller. Each adjustment frame includes a rotatable adjustment rod arranged along the Z-axis and connected to the frame via threads. The support roller and the pressure roller position the pipe, preventing it from tilting and allowing it to move in a predetermined direction. This ensures the pressure strip can better hold the pipe in place, improving the stability of the cutting equipment. Furthermore, the height of the pressure roller is adjustable, making the cutting equipment suitable for pipes of different heights and offering good versatility.

[0014] In the aforementioned online automated pipe cutting equipment, the sliding plate is provided with two sets of elongated adjustment holes arranged along the Y-axis. The sliding plate also has two supports, which are adjustablely positioned on the sliding plate by bolts passing through the supports and the adjustment holes. When necessary, the supports can be used to limit the Y-axis movement of the pipe, allowing the pipe to move in a set direction.

[0015] Compared with the prior art, the online automated pipe cutting equipment provided by this utility model has the following advantages:

[0016] 1. The sliding plate of this cutting equipment can move synchronously with the pipe along the X-axis. That is, the gantry, circular blade and clamping plate installed on the sliding plate all move synchronously with the pipe along the X-axis, so that the pipe can be cut by the circular blade without stopping the machine, realizing online cutting of the pipe and improving the cutting efficiency of the pipe.

[0017] 2. This cutting equipment uses support rollers and pressure rollers to position the pipe, preventing it from tilting and ensuring it moves in the set direction, thus improving the stability of the cutting equipment. The height of the pressure rollers is also adjustable, allowing the equipment to accommodate pipes of different heights and providing good versatility. Attached Figure Description

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1 As shown, this online automated pipe cutting equipment includes a frame 1, a sliding plate 2, a gantry frame 3, a circular blade 4, a first drive source 5, a pressure plate 6, a second drive source 10, a lead screw and slider assembly 11, a support roller 12, a pressure roller 13, and an adjusting frame 14. The left-right direction of the cutting equipment is defined as the X-axis, the front-back direction as the Y-axis, and the vertical direction as the Z-axis.

[0025] The sliding plate 2 is mounted on the frame 1 and is capable of reciprocating along the X-axis. Specifically, two guide rails along the X-axis are fixedly connected to the frame 1. Sliding blocks are fixedly connected to both sides of the sliding plate 2 and are slidably mounted on the guide rails. A second drive source 10 and a lead screw-slider assembly 11 are fixedly connected to the frame 1. The second drive source 10 drives the lead screw of the lead screw-slider assembly 11 to rotate. The slider of the lead screw-slider assembly 11 is fixedly connected to the sliding plate 2. The second drive source 10 is a drive motor. The second drive source 10 drives the lead screw to rotate, causing the slider to move along the X-axis, thereby moving the sliding blocks along the guide rails and enabling the sliding plate 2 to reciprocate along the X-axis.

[0026] A gantry frame 3 is fixedly connected to the sliding plate 2. The gantry frame 3 has a rotatable circular blade 4 that can reciprocate along the Y-axis and Z-axis. The sliding plate 2 has a long, narrow slit 9 along the Y-axis, located directly below the circular blade 4, through which the blade 4 can pass. Figure 2 , Figure 4 As shown, two pairs of first drive sources 5 are fixedly connected to the bottom of the sliding plate 2. Two long strip-shaped clamping plates 6 are arranged parallel to each other on the upper part of the sliding plate 2 and are arranged along the Y-axis. The two clamping plates 6 are located on both sides of the cutter 9. The output shaft of the first drive source 5 passes through the sliding plate 2 and is fixedly connected to the end of the clamping plate 6.

[0027] In this embodiment, the sliding plate 2 has eight guide holes 7, and the end of the pressing plate 6 is fixedly connected to a guide rod 8. The guide rod 8 passes through the guide hole 7. The first driving source 5 is a driving cylinder. In actual production, the number of guide holes 7 and guide rods 8 can be four or twelve. The first driving source 5 is a driving oil cylinder.

[0028] One end of the frame 1 is provided with a support roller 12 and a pressure roller 13. The pressure roller 13 is located directly above the support roller 12. Both the support roller 12 and the pressure roller 13 are arranged along the Y-axis direction. Figure 3 As shown, both ends of the pressure roller 13 are provided with adjustment frames 14. The adjustment frame 14 includes a rotatable adjustment rod 141, which is arranged along the Z-axis direction and is connected to the frame 1 by a thread. The sliding plate 2 is provided with two sets of elongated adjustment holes 15 arranged along the Y-axis direction. The sliding plate 2 is provided with two supports 16, which are adjustablely mounted on the sliding plate 2 by bolts passing through the supports 16 and the adjustment holes 15.

[0029] During operation, the extruded pipe from the injection molding machine moves along the X-axis into the cutting equipment, positioning it between the sliding plate 2 and the clamping plate 6. The second drive source 10 drives the slider via a lead screw, thereby controlling the moving speed of the sliding plate 2 to be the same as the moving speed of the pipe, ensuring that the sliding plate 2 and the pipe move synchronously along the X-axis. This causes the gantry 3, circular blade 4, and clamping plate 6 mounted on the sliding plate 2 to move synchronously along the X-axis with the pipe. The output shaft of the first drive source 5 retracts, causing the clamping plate 6 to press the pipe firmly onto the sliding plate 2. Then, the circular blade 4 moves along the Y-axis... The moving blade 4 cuts the pipe. After cutting, the circular blade 4 is lifted upward along the Z-axis and moves back to its original position along the Y-axis. At the same time, the output shaft of the first drive source 5 extends, so that the clamping plate 6 no longer presses down on the pipe. The second drive source 10 rotates in the opposite direction, so that the sliding plate 2 moves in the opposite direction along the X-axis, so that the pipe extruded from the injection molding machine pushes the cut pipe into the unloading frame. After the sliding plate 2 returns to its original position, the output shaft of the first drive source 5 retracts, so that the clamping plate 6 presses the pipe onto the sliding plate 2. The circular blade 4 works to cut the pipe. This process is repeated to cut multiple pipes.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
