Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing equipment, and specifically relates to an integrated equipment for cutting and end face treatment of crimp pipes. Background Art

[0002] In the fields of construction, machinery manufacturing, automobiles, aerospace, etc., the crimped pipe connection technology is widely used due to its advantages such as good sealing performance, convenient installation, and high reliability. The processing quality of crimp pipes directly affects the connection strength and sealing performance.

[0003] The Chinese utility model patent with the publication number CN210937701U discloses a bent pipe laser cutting device, which includes a bent pipe clamping mechanism, a dust removal mechanism arranged on one side of the bent pipe clamping mechanism, and a laser cutting mechanism arranged above the bent pipe clamping mechanism. The bent pipe clamping mechanism includes: a rotating mechanism, a rotating motor for driving the rotating mechanism to work. The rotating mechanism includes: a fixed bracket, a driven gear, and a turntable. Compared with the prior art,

[0004] The setting of the bent pipe clamping mechanism helps to clamp the bent pipe, ensuring the stability and accuracy during cutting; under the action of the dust removal device, the dust removal traveling crane can move to help the whole dust removal pipe enter the bent pipe for dust removal; the laser cutting head can move up, down, left, and right, and can cut the pipe in all directions, and it can cooperate with the bent pipe clamping mechanism. Driven by the rotation of the rotating motor, the turntable rotates to realize the all-round cutting of the pipe.

[0005] However, there are still some deficiencies in actual use. For example, the above-mentioned device can only complete the cutting operation of bent pipes and cannot perform polishing treatment on the end face after cutting. If defects such as burrs, flash, and micro-roughness generated during the cutting process are not eliminated in time, it will directly affect the crimping fit accuracy between the bent pipe and the pipe fitting, and even lead to sealing failure. In addition, additional polishing equipment or manual grinding processes need to be configured, significantly reducing production efficiency and increasing processing costs.

[0051] Embodiment

[0052] Please refer to Figures 1 to 10 , this embodiment provides an integrated device for cutting and end face treatment of a crimped pipe, including: a base 1, a workpiece clamping mechanism 2, a cutting mechanism 3, and an end grinding mechanism 4;

[0053] Among them, an installation frame 101 is fixedly installed on the top of the base 1;

[0054] Among them, the workpiece clamping mechanism 2 is used to fix the bent pipe to be processed. There are two sets of clamping units 207 on the workpiece clamping mechanism 2 that can operate alternately. The workpiece clamping mechanism 2 is installed on the base 1; the cutting mechanism 3, and the cutting mechanism 3 is used to perform cutting operations on the bent pipe;

[0055] Among them, the end grinding mechanism 4, and the end grinding mechanism 4 is used to perform polishing operations on the end of the cut bent pipe; both the cutting mechanism 3 and the end grinding mechanism 4 are installed on the installation frame 101.

[0056] By providing the base 1, it provides a support and a stable installation foundation for the entire device. The installation frame 101 is fixed on the base 1 and is used to install the cutting mechanism 3 and the end grinding mechanism 4. The two sets of clamping units 207 of the workpiece clamping mechanism 2 operate alternately, first fixing the bent pipe to be processed, which facilitates the cutting mechanism 3 to cut the bent pipe. After cutting, the end grinding mechanism 4 performs polishing treatment on the end of the cut bent pipe.

[0057] In this embodiment, the workpiece clamping mechanism 2 includes a first motor 201 and a support frame 202. Both the first motor 201 and the support frame 202 are fixedly installed on the base 1. A first rotating shaft 205 is rotatably connected inside the support frame 202. One end of the first rotating shaft 205 is fixedly connected to a first driven gear 203, and the other end of the first rotating shaft 205 is fixedly connected to a first rotating seat 206. A first driving gear 204 is fixedly connected to the rotating shaft of the first motor 201. The first driven gear 203 meshes with the first driving gear 204. The two sets of clamping units 207 are respectively installed at both ends of the first rotating seat 206.

[0058] During use, after the first motor 201 starts, it drives the first driving gear 204 to rotate. Since the first driving gear 204 meshes with the first driven gear 203, the first driven gear 203 rotates accordingly, and then drives the first rotating shaft 205 fixedly connected thereto to rotate within the support frame 202. The rotation of the first rotating shaft 205 drives the first rotating seat 206 to rotate, so that the two sets of clamping units 207 installed at both ends of the first rotating seat 206 alternately reach the working position to achieve alternating operations.

[0059] In this embodiment, the two sets of clamping units 207 both include a second motor 2071, a worm and worm gear box 2072, a second rotating seat 2073 and a lead screw 2074. The second motor 2071 and the worm and worm gear box 2072 are both fixedly installed on one side of the first rotating seat 206 close to the support frame 202. The rotating shaft of the second motor 2071 is fixedly connected to the input shaft of the worm and worm gear box 2072. The output shaft of the worm and worm gear box 2072 rotates through the first rotating seat 206 and is fixedly connected to one side of the second rotating seat 2073. The lead screw 2074 is rotatably installed on the side of the second rotating seat 2073 away from the second motor 2071 through a pedestal bearing. A third motor 2075 is fixedly installed at the upper end of the second rotating seat 2073. The rotating shaft of the third motor 2075 is fixedly connected to one end of the lead screw 2074. The thread directions at both ends of the lead screw 2074 are opposite. Both ends of the lead screw 2074 are threadedly rotatably connected to clamping arms 2076. A limiting slide rail 2077 is fixedly installed on the second rotating seat 2073. The clamping arms 2076 are slidably installed on the limiting slide rail 2077. One end of the clamping arm 2076 away from the second rotating seat 2073 is rotatably installed with a clamping seat 2078 through a rotating rod. A fourth motor 2079 is fixedly installed on one of the clamping arms 2076. The rotating shaft of the fourth motor 2079 is fixedly connected to the rotating rod on this clamping arm 2076. The cross section of the clamping seat 2078 is arranged in a V shape. The axis of the bent pipe to be clamped is collinear with the axis of the output shaft of the worm and worm gear box 2072. The laser head of the laser cutting machine 304 is located directly above the axis of the output shaft of the worm and worm gear box 2072 at the cutting station.

[0060] During use, the third motor 2075 is started, thereby driving the lead screw 2074 to rotate on the second rotating seat 2073. Since the thread directions at both ends of the lead screw 2074 are opposite, when the lead screw 2074 rotates, the clamping arms 2076 at both ends move linearly towards or away from each other along the lead screw 2074 under the restriction of the limit slide rail 2077, thereby realizing the clamping or loosening of the bent pipe. The second motor 2071 is started, and the power is transmitted to the input shaft of the worm and gear box 2072 through the rotating shaft. After deceleration and commutation by the worm and gear box 2072, the output shaft drives the second rotating seat 2073 to rotate. The fourth motor 2079 can drive the rotating rod to rotate, thereby adjusting the angle of the clamping seat 2078. At the same time, the two ends of the bent pipe can be switched, and the V-shaped clamping seat 2078 can adapt to bent pipes of different diameters.

[0061] In this embodiment, the cutting mechanism 3 includes a first X-axis linear module 301, a first Y-axis linear module 303, and a laser cutting machine 304. The first X-axis linear module 301 is fixedly installed on the top of the mounting frame 101. An installation seat 302 is fixedly installed on the slide table of the first X-axis linear module 301. The first Y-axis linear module 303 is fixedly installed at one end of the installation seat 302 away from the first X-axis linear module 301. The laser cutting machine 304 is fixedly installed on the slide table of the first Y-axis linear module 303.

[0062] During use, the first X-axis linear module 301 can drive the installation seat 302 to move along the X-axis direction, and the first Y-axis linear module 303 can drive the laser cutting machine 304 to move along the Y-axis direction. Through the coordinated movement of the first X-axis linear module 301 and the first Y-axis linear module 303, the laser cutting machine 304 is moved to a suitable position of the bent pipe to be cut, and then the laser cutting machine 304 emits laser to cut the bent pipe.

[0063] In this embodiment, the end grinding mechanism 4 includes a second X-axis linear module 401, a fixing frame 402, and a grinding head 403. The second X-axis linear module 401 is fixedly installed on the mounting frame 101, and the fixing frame 402 is fixedly installed on the slide table of the second X-axis linear module 401. The grinding head 403 includes a main housing and a transmission pipe 4031. The transmission pipe 4031 is rotatably installed on the fixing frame 402 through two sets of support seats 40310. One end of the transmission pipe 4031 rotatably penetrates the main housing. The main housing includes a first housing 4032 and a first cover plate 4033. The first cover plate 4033 is fixedly installed at the opening of the first housing 4032 through bolts. A plurality of grinding rollers 4034 are rotatably installed on the first housing 4032. The plurality of grinding rollers 4034 are circularly arrayed and equally spaced on the first cover plate 4033. The transmission pipe 4031 is drivingly connected to the grinding rollers 4034 through a first transmission member, and the first housing 4032 is drivingly connected to the transmission pipe 4031 through a second transmission member. The first transmission member includes a second bevel gear 4036. The second bevel gear 4036 is fixedly sleeved on the transmission pipe 4031. The second bevel gear 4036 is located inside the first housing 4032. A first bevel gear 4035 is fixedly installed on the rotating shaft of the grinding roller 4034. The first bevel gear 4035 meshes with the second bevel gear 4036. The second transmission member includes a first transmission gear 4037 and an annular internal gear 4039. The annular internal gear 4039 is fixedly installed inside the first housing 4032. The first transmission gear 4037 is fixedly sleeved on the transmission pipe 4031. A second transmission gear 4038 is rotatably connected inside the first housing 4032. Both the second transmission gear 4038 and the first transmission gear 4037 are located inside the annular internal gear 4039. The first transmission gear 4037 meshes with the second transmission gear 4038, and the second transmission gear 4038 meshes with the annular internal gear 4039.

[0064] During use, the second X-axis linear module 401 drives the fixing frame 402 and the grinding head 403 to move along the X-axis direction to the end of the bent pipe after cutting. When the transmission pipe 4031 rotates, the second bevel gear 4036 fixedly sleeved thereon rotates accordingly. Through meshing with the first bevel gear 4035, it drives the grinding rollers 4034 to rotate, realizing the grinding of the end of the bent pipe. At the same time, the first transmission gear 4037 rotates with the transmission pipe 4031. Through meshing with the second transmission gear 4038 and the annular internal gear 4039, it drives the main housing to rotate accordingly, thereby realizing the all-round grinding of the end face of the bent pipe.

[0065] In this embodiment, a driving mechanism 404 for driving the grinding head 403 to rotate is fixedly installed on the fixing frame 402. The driving mechanism 404 includes a fifth motor 4041 and a second driven gear 4043. The fifth motor 4041 is fixedly installed on the fixing frame 402, and a second driving gear 4042 is fixedly installed on the rotating shaft of the fifth motor 4041. The second driving gear 4042 meshes with the second driven gear 4043.

[0066] During use, the fifth motor 4041 is started to drive the second driving gear 4042 to rotate. Since the second driving gear 4042 meshes with the second driven gear 4043, the second driven gear 4043 rotates, thereby driving the grinding head 403 to rotate and providing power for the operation of the grinding head 403.

[0067] Specifically, a multi-axis collaborative cutting trajectory equation is introduced in this embodiment:

[0068]

[0069] This equation is derived from the three-dimensional heat conduction differential equation by combining the laser power density distribution and the heat conduction characteristics of the pipe. The moment of inertia of the pipe (R 2 -r 2) is introduced to reflect the cutting resistance, and the cubic root relationship reflects the non-linear characteristics of the energy utilization efficiency.

[0070] Parameter description:

[0071] D is the outer diameter of the elbow pipe (mm); Plaser is the rated power of the laser (W); ηc is the optical path transmission efficiency (0.8 - 0.95); Km is the material thermal conductivity coefficient (W / m·K); ρ is the material density (kg / m 3 );

[0072] Example application:

[0073] When cutting a DN50 stainless steel pipe (D = 60mm, p = 7930kg / m 3 , km = 15W / m·K), substituting a laser power of 3000W gives an optimal cutting speed Vopt = 2.8mm / s. Actual tests show that compared with traditional constant-speed cutting, this speed strategy can significantly reduce the thickness of the oxide layer at the cut.

[0074] At the same time, a magnetic coupling dust collection efficiency equation is also introduced in this embodiment:

[0075]

[0076] The equation is based on the coupling analysis of the eddy current effect and the fluid pressure drop, and the exponential correction term is obtained by fitting the experimental data. The introduction of the number of magnetic poles Nmag and the gap magnetic permeability μgap accurately describes the characteristics of non-contact transmission.

[0077] Parameter Description:

[0078] Wrotor is the transmission tube speed (rad / s);

[0079] ΔP is the filter pressure difference (Pa);

[0080] A filter is the filtration area (m2);

[0081] A inlet is the cross-sectional area of ​​the dust collection port (m2);

[0082] When the equipment is running at 1500 rpm, the equation predicts that the dust collection efficiency can be greatly improved. The measured data shows that the amount of debris residue is greatly reduced and the life of the magnetic coupling components is greatly extended compared with traditional centrifugal dust collection systems.

[0083] In this embodiment, a dust collecting mechanism 405 is also included. The dust collecting mechanism 405 includes a second cover plate 4051 and a second shell 4052. The second shell 4052 is fixedly mounted on the second cover plate 4051 by screws. The second cover plate 4051 is fixedly mounted on a side of a support seat 40310 away from the grinding head 403. One end of the transmission tube 4031 away from the grinding head 403 rotates and extends into the second shell 4052. A rotating shaft is rotatably mounted inside the second shell 4052, and a fan blade 4053 is fixedly connected to the rotating shaft. A dust outlet 40313 is provided at one end of the transmission tube 4031 close to the fan blade 4053, and a dust outlet 40313 is provided at one end of the transmission tube 4031 away from the fan blade 4053.

[0084] During operation, when the drive tube 4031 rotates, it drives the copper rotor 4055 to rotate. The magnetic coupling drive assembly composed of the copper rotor 4055 and the permanent magnet rotor 4056 drives the permanent magnet rotor 4056 to rotate through magnetic force, and then the rotating shaft and the fan blade 4053 rotate. The fan blade 4053 on the rotating shaft rotates accordingly to generate suction. The dust generated during the cutting process enters the drive tube 4031 through the central dust collection port 40312, and then enters the second housing 4052 from the dust outlet 40313 to achieve the dust collection function. The dust entering the second housing 4052 is filtered by the filter screen 4054, and the clean air is discharged from the air outlet 40521.

[0085] In this embodiment, a plurality of side dust collection ports 40311 are provided on the side surface of one end of the drive tube 4031 away from the fan blade 4053. Through the provided side dust collection ports 40311, when the polishing roller 4034 polishes the end face of the bent pipe, the generated debris and dust can enter the drive tube 4031 from the side dust collection ports 40311.

[0086] In this embodiment, an annular dust-proof cover 4057 is fixedly sleeved on the copper rotor 4055, and the end face of the annular dust-proof cover 4057 is in rotational contact with the filter screen 4054. The annular dust-proof cover 4057 rotates with the copper rotor 4055, and its end face is in rotational contact with the filter screen 4054, which can prevent dust from entering between the copper rotor 4055 and the permanent magnet rotor 4056 and protect the normal operation of the magnetic coupling drive assembly.

[0087] Working principle:

[0088] The first motor 201 drives the first rotating shaft 205 to rotate, driving the two groups of clamping units 207 on the first rotating seat 206 to be respectively in the loading position station A and the standby position station B.

[0089] Workpiece loading and clamping:

[0090] The bent pipe to be processed is placed on the V-shaped clamping seat 2078 at station A. The third motor 2075 drives the lead screw 2074 to rotate, so that the clamping arms 2076 move towards each other to clamp the bent pipe. The fourth motor 2079 adjusts the angle of the clamping seat 2078 to ensure that the axis of the bent pipe is collinear with the output shaft of the worm and gear box 2072. The axis of the bent pipe at the cutting position is collinear with the axis of the drive tube 4031.

[0091] Station switching:

[0092] The first motor 201 rotates reversely by 180°, driving the first rotating seat 206 to rotate through the gear pair 203 / 204. The clamping unit 207 at station A enters the cutting position, and the clamping unit 207 at station B enters the loading position.

[0093] Laser cutting:

[0094] The first X-axis linear module 301 and the first Y-axis linear module 303 cooperate to move the laser cutting machine 304 to the cutting point, and emit a laser beam to vertically cut the bent pipe. During cutting, the second X-axis linear module 401 drives the transmission pipe 4031 close to the bent pipe, so that the central dust collection port 40312 extends into the bent pipe, and then the fifth motor 4041 is started to collect the debris generated by cutting.

[0095] End face grinding:

[0096] The second X-axis linear module 401 drives the grinding head 403 close to the end of the cut bent pipe. The fifth motor 4041 drives the transmission pipe 4031 to rotate through the second driving gear 4042 and the second driven gear 4043, driving the grinding roller 4034 to rotate self and the main housing to rotate 360°, realizing full circumferential polishing.

[0097] Dust collection treatment:

[0098] When the transmission pipe 4031 rotates, the copper rotor 4055 drives the permanent magnet rotor 4056 through magnetic coupling, driving the fan blade 4053 to rotate to generate suction. The dust and debris generated by cutting or grinding enter the transmission pipe 4031 through the central dust collection port 40312 and the side dust collection port 40311, and are discharged into the second housing 4052 through the dust outlet 40313. The filter screen 4054 intercepts the dust, and the clean air is discharged from the air outlet 40521. It should be noted that when the grinding roller 4034 grinds the end face of the bent pipe, there is a gap between the first cover plate 4033 and the end face of the bent pipe, and the debris and dust generated by grinding mainly enter the transmission pipe 4031 through the side dust collection port 40311.
