Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe cutting, in particular to an automatic feeding sawing machine used for corrugated pipe cutting. Background Art

[0002] With the rapid development of modern industry, bellows, as an important industrial component, has been widely used in many industries such as petrochemical, aerospace, automobile manufacturing, and medical equipment. With its good flexibility, pressure resistance and sealing performance, bellows play an irreplaceable role in pipeline connection, vibration reduction, noise reduction, thermal compensation, etc. However, with the expansion of the scope of use of bellows and the increase in the frequency of use, the demand for supporting processing equipment, especially cutting equipment, has become increasingly prominent.

[0003] There are two main types of corrugated pipe cutting equipment on the market: manual cutting equipment and laser cutting equipment. Among them, although the manual cutting method has lower equipment costs, it has obvious disadvantages such as poor cutting accuracy, low efficiency, and high labor intensity, which makes it difficult to meet the needs of modern production. Although laser cutting technology has advantages such as high cutting accuracy and good incision quality, its high equipment cost, complex operation requirements and high energy consumption make it more suitable for large-scale batch production. For small batches and multiple varieties of corrugated pipe cutting needs, the use of laser cutting often results in low equipment utilization, high production costs, and other problems, resulting in waste of resources.

[0004] In addition, some existing general-purpose pipe cutting equipment also has many problems when used for corrugated pipe cutting. Due to the special wave structure of corrugated pipes, traditional clamp designs often have difficulty in achieving stable and reliable clamping: too little clamping force will cause the workpiece to shift during cutting, affecting cutting accuracy; too much clamping force will easily cause the corrugated pipe to deform and flatten, affecting product quality. Summary of the invention

[0005] In view of the above problems, the present invention provides an automatic feeding sawing machine for corrugated pipe cutting to solve the problem that the clamping device of the existing cutting equipment is not suitable for clamping the corrugated pipe.

[0006] The technical scheme used in the present invention is: an automatic feeding sawing machine for corrugated pipe cutting, comprising a feeding mechanism, a discharging mechanism, a positioning mechanism and a cutting and grinding mechanism; the positioning mechanism comprises a positioning frame sliding base supporting the positioning mechanism, two positioning frames slidably mounted in a slide groove provided on the positioning frame sliding base and provided with a cylinder on one side, a distance adjustment threaded rod slidably mounted in a slide hole provided at a corner position of the upper end of the positioning frame, an adjustment nut rotatably connected to the positioning frame to drive the distance adjustment threaded rod to move, a U-shaped frame fixedly connected to the lower end of the distance adjustment threaded rod, and an electromagnet provided with an internal cylinder installed in the U-shaped frame; The cutting and grinding mechanism includes a saw blade adjusting plate with a rack on its side, a power assembly II for controlling the movement of the saw blade adjusting plate, a saw blade mounting block slidably installed in a chute provided at the lower end of the saw blade adjusting plate, friction blocks provided on both sides of the saw blade mounting block for grinding the edges of the bellows, a saw blade rotatably connected to the saw blade mounting block through a shaft and having a coil spring for resetting on the shaft, a rack frame fixedly installed at the upper end of the saw blade mounting block, and a power assembly III for controlling the reciprocating movement of the rack frame.

[0007] Preferably, the cutting and grinding mechanism further includes two cutting boxes arranged in a mirror image with a spacing in the middle, a rotating collar rotatably installed between the two cutting boxes and located in the spacing between the two cutting boxes, and a power assembly I for driving the rotating collar to rotate.

[0008] Preferably, the rotating collar is provided with a chute for installing the saw blade adjusting plate.

[0009] Preferably, there are two positioning frames, and each positioning frame is provided with two distance adjusting threaded rods, two adjusting nuts, two electromagnets, and two U-shaped frames.

[0010] Preferably, the feeding mechanism includes two roller boxes, two sets of rollers installed in the two roller boxes, a bracket fixedly installed with one roller box, an adjusting rod for adjusting the relative position of the upper and lower roller boxes, and a clamping strip for fixing the adjusting rod.

[0011] Preferably, a plurality of rollers arranged in a linear array are rotatably installed in the roller box fixedly installed on the bracket, and they are connected by a chain group. At the same time, one roller is connected to a motor, and the motor drives the roller to rotate for feeding operation.

[0012] Preferably, the discharging mechanism includes a discharging rack for receiving the bellows, which is composed of a bracket, a roller box, and a plurality of rollers arranged in a linear array installed in the roller box; a scale is provided on the side of the discharging rack for measuring the length of the bellows, which is convenient for cutting the bellows to a specified length.

[0013] Preferably, the saw blade is made of a material not attracted by the electromagnet to prevent the saw blade from being attracted by the electromagnet during operation. The beneficial effects of the present invention are as follows: 1. The electromagnet contacts the bellows under the push of the cylinder. After contact, the electromagnet is energized to generate magnetism, so that the electromagnet attracts the bellows. At this time, the multiple electromagnets fix the bellows, which is convenient for cutting operation. By fixing the bellows with the electromagnet, the problem that the bellows is easily deformed by the clamp is solved, and at the same time, the electromagnet can also be applied to different bellows; 2. After the saw blade contacts the bellows, the outer wall of the bellows pushes the saw blade to flip, so that the saw teeth of the saw blade contact the outer wall of the bellows. The saw blade moves repeatedly to saw open the bellows. After being sawed open, half of the saw blade enters the bellows under the elastic force of the coil spring, and then the saw blade rotates around the bellows to saw open the bellows completely. When cutting, the saw blade first cuts a small opening in the bellows and then enters the bellows for cutting, which reduces the force on the outer wall of the bellows during the cutting process and reduces the possibility of the bellows deforming due to force; 3. After sawing, move the two positioning frames in the opposite direction to increase the gap between the two positioning frames. At this time, the power component II then drives the saw blade adjusting plate to move downward, so that the two friction blocks contact the two side edges of the cut bellows respectively, and polish the burrs generated after cutting the bellows to make it smooth, which is convenient for subsequent use. Being able to polish after cutting reduces the process of polishing required after cutting and improves the efficiency; 4. According to the size of the bellows, rotate the adjusting nut to drive the distance adjusting screw rod to move, thereby driving the U-shaped frame to move, and then driving the electromagnet to move, so that the positioning mechanism can be applicable to bellows of different sizes.

[0035] Working principle: When cutting corrugated pipes, place the corrugated pipe to be cut on the rollers 3 in the roller box 2 set on the bracket 1 using this equipment first. Then adjust the position of the roller box 2 set above so that the rollers 3 in the upper and lower roller boxes 2 clamp the corrugated pipe. At this time, insert the clamping strip 5 into the clamping holes set on the adjusting rod 4 to clamp the adjusting rod 4, and then fix the positions of the upper and lower roller boxes 2. At this time, the rollers 3 in the lower roller box 2 rotate driven by the motor, and then drive the corrugated pipe to move towards the position of the cutting and grinding mechanism until the corrugated pipe moves onto the discharge rack 6. According to the scale set on the discharge rack 6, know the length of the corrugated pipe. When the length of the corrugated pipe reaches the required length, the electromagnet 12 contacts the corrugated pipe under the push of the cylinder. After contact, the electromagnet 12 is energized to generate magnetism, and then the electromagnet 12 is attracted to the corrugated pipe. At this time, multiple electromagnets 12 fix the corrugated pipe, thus facilitating the cutting operation; Then the power assembly II 17 drives the rack set on the side of the saw blade adjusting plate 16 to move, and then drives the saw blade adjusting plate 16 to move downward, thereby driving the saw blade 20 to contact the corrugated pipe. After contact, the outer wall of the corrugated pipe pushes the saw blade 20 to flip, making the torsion spring set on the shaft of the saw blade 20 stressed, and then making the saw teeth of the saw blade 20 contact the outer wall of the corrugated pipe. At this time, the half-rack set in the power assembly III 22 meshes with the two racks set in the rack frame 21 in sequence, thereby driving the rack frame 21 to move back and forth, and then driving the saw blade 20 to move back and forth repeatedly, so as to saw open the corrugated pipe. After sawing, the saw blade 20 flips under the elastic force of the torsion spring, so that half of the saw blade 20 enters the corrugated pipe, and the saw blade 20 and the saw blade adjusting plate 16 are in a horizontal state. At this time, the saw blade 20 moves repeatedly, and the power assembly I 9 drives the rotating collar 8 to rotate around the corrugated pipe, thereby driving the saw blade adjusting plate 16 and the saw blade 20 to rotate around the corrugated pipe, and then sawing open the entire corrugated pipe; After sawing, the cylinder connected to the positioning frame 11 drives the positioning frame 11 to move, so that the two positioning frames 11 move in opposite directions, and then the gap between the two separated positioning frames 11 becomes larger. At this time, the power assembly II 17 then drives the saw blade adjusting plate 16 to move downward, so that the two friction blocks 18 contact the two side edges of the cut corrugated pipe respectively. At this time, the power assembly I 9 drives the rotating collar 8 to rotate around the corrugated pipe, thereby driving the friction blocks 18 to rotate around the corrugated pipe, so as to polish the burrs generated after cutting the corrugated pipe to make it smooth and facilitate subsequent use; According to the size of the corrugated pipe, rotate the adjusting nut 15 to drive the distance adjusting screw rod 14 to move, thereby driving the U-shaped frame 13 to move, and then driving the electromagnet 12 to move, so that the positioning mechanism can be suitable for corrugated pipes of different sizes; Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
