Description

Technical Field

[0001] The utility model belongs to the field of welded pipe processing, and more specifically relates to a weld burr processing device. The utility model also relates to a pipe production line. Background Art

[0002] Welded pipe is the material used to make pipe fittings. Different pipe fittings require different welded pipes, and the quality of the welded pipe directly determines the quality of the fitting. This type of welded pipe is commonly used in construction projects, power plants, chemical plants, and other applications.

[0003] Among them, the more widely used welded pipes are generally rolled from steel strips. The steel strips are first unwound by an unwinding device and then pulled to the rolling mill by a traction wheel. The steel strips are extruded into a preset cross-sectional shape during the rolling process of multiple rolling mills. After the steel strips are rolled from the rolling mill, they enter the downstream welding and burr scraping stations in sequence to weld the joints of the welded pipes and remove burrs. After the above operations are completed, the welded pipes can be cut to the required specifications.

[0004] In the process of scraping the welding marks of the weld seam, the burrs scraped off from the weld pipe are similar in shape to iron wire. If special equipment is not used to collect them, the continuous burrs will interfere with the normal operation of the production line. In this regard, some manufacturers will use equipment such as squeezing rollers to cut off the burrs before scraping them. However, although the weld burrs have residual heat and low hardness, the squeezing roller will still leave squeezing marks on the outer periphery of the pipe during the squeezing of the burrs, affecting the appearance quality of the pipe. The existing winding device needs to coil the burrs by installing an I-wheel. When the I-wheel is not set, the burrs are easily stuck in the area between the coil plate and the base, which is extremely inconvenient to use and urgently needs improvement. Utility Model Content

[0005] The utility model aims to provide a weld burr processing device to solve the technical problem that burrs are easily stuck between the coil plate and the base when the existing coil plate is not provided with an I-shaped wheel.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a weld burr treatment device, comprising a machine base and a coiling mechanism provided on the machine base, wherein the coiling mechanism comprises:

[0007] The winding drum includes a driving shaft and a plurality of winding plates evenly arranged around the axis of the driving shaft. The length direction of each winding plate is parallel to the axis of the driving shaft. Each winding plate can approach or move away from the driving shaft along the diameter direction of the driving shaft. The inner plate surface and the outer plate surface of the winding plate are both arc surfaces, and the radial lines of the inner plate surface and the outer plate surface are parallel to the axis of the driving shaft. The driving shaft can drive each winding plate to rotate around its own axis.

[0008] In one possible implementation, the winding mechanism also includes a guide plate coaxially connected to the drive shaft, and the guide plate rotates synchronously with the drive shaft. The guide plate is provided with a guide hole, and the length direction of the guide hole coincides with the radial line of the guide plate. The winding plate slides along the length direction of the guide hole to adapt to the guide hole.

[0009] In a possible implementation, the winding mechanism also includes a connecting sleeve, a first connecting rod and a second connecting rod. The connecting sleeve is a lockable sliding sleeve arranged on the outer periphery of the drive shaft, and the connecting sleeve rotates synchronously with the drive shaft. One end of the first connecting rod is provided with a first hinge shaft hinged to the inner plate surface, and the other end is provided with a second hinge shaft hinged to the outer periphery of the connecting sleeve. One end of the second connecting rod is provided with a third hinge shaft hinged to the inner plate surface, and the other end is provided with a fourth hinge shaft hinged to the outer periphery of the connecting sleeve. The first connecting rod is parallel to the second connecting rod, and the first hinge shaft, the second hinge shaft, the third hinge shaft and the fourth hinge shaft are parallel to each other and are perpendicular to the axis of the drive shaft.

[0010] In one possible implementation, the weld burr processing equipment also includes a guide wheel group, and the guide wheel group is provided at one end of each coil plate that extends toward the guided through hole; the guide wheel group includes a first guide wheel and a second guide wheel, and the first guide wheel and the second guide wheel are respectively rolled on both sides of the guide plate, and the rotation axes of the first guide wheel and the second guide wheel are parallel to each other and perpendicular to the axis of the drive shaft, and the first guide wheel and the second guide wheel both roll along the length direction of the guide through hole.

[0011] In a possible implementation, the outer periphery of one end of the drive shaft sleeve provided with a connecting sleeve is formed with an external thread, and the outer peripheral thread of the external thread is adapted to be fitted with a fixing nut, which enables the connecting sleeve to move axially along the drive shaft.

[0012] In one possible implementation, a connecting bearing is provided between the fixing nut and the connecting sleeve, the fixing nut is rotatably adapted to the end of the connecting sleeve through the connecting bearing, and the connecting bearing can form an axial lock between the fixing nut and the connecting sleeve.

[0013] In a possible implementation, a locking through hole is formed on an outer periphery of the fixing nut, an inner wall of the locking through hole is formed with an internal thread, and a positioning bolt is screwed into the locking through hole.

[0014] In one possible implementation, a connecting plate is provided on the outer periphery of the connecting sleeve, the length direction of the connecting plate extends along the axial direction of the connecting sleeve, and the width direction of the connecting plate extends along the radial direction of the connecting sleeve, and the first hinge shaft and the fourth hinge shaft are both connected to the connecting plate.

[0015] Compared with the existing technology, the beneficial effect of the weld burr processing equipment provided by the utility model is that: driven by the drive shaft, each coil plate rotates around the axis of the drive shaft, which makes it easier to roll the burrs to the outer periphery of the coil drum. After the winding is completed, the utility model can also remove the circled burrs by bringing the coil plates closer to each other, making the collection of burrs more convenient; in addition to the above beneficial effects, each coil plate in the utility model will only move along the radial line of the coil drum, and the coil plate will not move along the axial direction of the drive shaft at the same time when approaching or moving away from the drive shaft. In this way, the position control of the coil plate is more stable, and the burrs will not be dislocated due to the horizontal movement of the coil plate, which is conducive to the continuous collection of burrs.

[0016] Another object of the present invention is to provide a pipe production line, comprising the weld burr processing equipment described above.

[0017] Compared with the prior art, the pipe production line in the present invention has all the benefits of the above-mentioned weld burr processing equipment, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Please also refer to Figures 1 to 3The weld burr treatment device provided by the present invention is now described. The weld burr treatment device in the present invention comprises a machine base 1 and a coiling mechanism 2 provided on the machine base 1, wherein the coiling mechanism 2 comprises a coiling drum 21, and the coiling drum 21 specifically comprises a drive shaft 211 and a plurality of coiling plates 212 evenly arranged around the axis of the drive shaft 211, the length direction of each coiling plate 212 is parallel to the axis of the drive shaft 211, and each coiling plate 212 can approach or move away from the drive shaft 211 along the diameter direction of the drive shaft 211, and the inner plate surface and the outer plate surface of the coiling plate 212 are both arc surfaces, and the radial lines of the inner plate surface and the outer plate surface are parallel to the axis of the drive shaft 211, and the drive shaft 211 can drive each coiling plate 212 to rotate around its own axis.

[0031] Compared with the prior art, the beneficial effect of this embodiment is that: driven by the drive shaft 211, each coiling plate 212 rotates around the axis of the drive shaft 211, thereby facilitating the winding of the burrs to the outer periphery of the coiling drum 21. After the winding is completed, this embodiment can also remove the circled burrs by bringing the each coiling plate 212 closer to each other, making the collection of burrs more convenient; in addition to the above beneficial effects, each coiling plate 212 in this embodiment will only move along the radial line of the coiling drum 21, and the coiling plate 212 will not move along the axial direction of the drive shaft 211 at the same time when approaching or moving away from the drive shaft 211. In this way, the position control of the coiling plate 212 is more stable, and the burrs will not be dislocated due to the horizontal movement of the coiling plate 212, which is conducive to the continuous collection of burrs.

[0032] Based on the above embodiment, in order to guide the movement of the coiling plate 212, in a possible implementation method, the coiling mechanism 2 also includes a guide plate 22 coaxially connected to the drive shaft 211, and the guide plate 22 rotates synchronously with the drive shaft 211, and the guide plate 22 is provided with a guide through-hole 221, and the length direction of the guide through-hole 221 coincides with the radial line of the guide plate 22, and the coiling plate 212 slides along the length direction of the guide through-hole 221 to adapt to the guide through-hole 221, so as to guide the movement of the coiling plate 212 through the guide through-hole 221 provided on the guide plate 22, and at the same time, the guide plate 22 can also make the burrs on the coiling plate 212 more regular, and since the coiling plate 212 has a part slidingly connected to the guide through-hole 221, the burrs will not be rolled up in the gap between the guide plate 22 and the coiling plate 212 during the winding process, so that the coiling plate 212 in this embodiment is more efficient in collecting burrs.

[0033] Based on the above embodiments, a more preferred embodiment is proposed. Specifically, the above winding mechanism 2 also includes a connecting sleeve 23, a first connecting rod 24 and a second connecting rod 25. The connecting sleeve 23 is a lockable sliding sleeve arranged on the outer periphery of the driving shaft 211, and the connecting sleeve 23 rotates synchronously with the driving shaft 211. One end of the first connecting rod 24 is provided with a first hinge axis hinged to the inner plate surface, and the other end is provided with a second hinge axis hinged to the outer periphery of the connecting sleeve 23. One end of the second connecting rod 25 is provided with a third hinge axis hinged to the inner plate surface, and the other end is provided with a fourth hinge axis hinged to the outer periphery of the connecting sleeve 23. The first connecting rod 24 is parallel to the second connecting rod 25, and the first hinge axis, the second hinge axis, the third hinge axis and the fourth hinge axis are parallel to each other and are perpendicular to the axis of the driving shaft 211. The quadrilateral structure composed of each hinge axis is used to position the relative position of the winding plate 212 and the connecting roller, so that the axial movement of the connecting roller can drive the radial movement of the winding plate 212.

[0034] In one possible implementation, the weld burr processing equipment also includes a guide wheel group 3, and each coil plate 212 is provided with a guide wheel group 3 at one end thereof that extends toward the guided through hole 221; the guide wheel group 3 includes a first guide wheel 31 and a second guide wheel 32, and the first guide wheel 31 and the second guide wheel 32 are respectively rolled on both sides of the guide disk 22, and the rotation axes of the first guide wheel 31 and the second guide wheel 32 are parallel to each other and perpendicular to the axis of the drive shaft 211, and the first guide wheel 31 and the second guide wheel 32 both roll along the length direction of the guide through hole 221, so that the radial movement of the coil plate 212 can be guided by the two guide wheels, and the sliding of the coil plate 212 on the guide disk 22 can be made smoother by the rotation of the guide wheels.

[0035] It should be noted that, in order to prevent the burrs on the coiled material plate 212 from interfering with the rotation of the two guide wheels, the wheel surfaces of the two guide wheels are lower than the outer plate surface of the coiled material plate 212 .

[0036] In one possible implementation, the outer periphery of one end of the driving shaft 211 is provided with a connecting sleeve 23, and an external thread 2111 is formed. The outer peripheral thread of the external thread 2111 is adapted to a fixing nut 214. The fixing nut 214 can enable the connecting sleeve 23 to move axially along the driving shaft 211. In this way, the present embodiment can move the connecting sleeve 23 like the guide disk 22 by locking the fixing nut 214, thereby stretching the coiling plate 212. Similarly, the present embodiment can adjust the diameter of the coiling drum 21 by loosening the fixing nut 214 to bring the various coiling plates 212 closer to each other, which not only facilitates the collection of burrs by the coiling mechanism 2, but also facilitates the removal of the wound burrs from the coiling mechanism 2 by bringing the various coiling plates 212 closer to each other.

[0037] In one possible implementation, a connecting bearing 213 is provided between the fixing nut 214 and the connecting sleeve 23. The fixing nut 214 is rotatably adapted to the end of the connecting sleeve 23 via the connecting bearing 213, and the connecting bearing 213 can form an axial lock between the fixing nut 214 and the connecting sleeve 23. With this arrangement, the fixing nut 214 in this embodiment can always be connected to the connecting sleeve 23 described above via the connecting bearing 213 during rotation, and can drive the connecting sleeve 23 to move axially during rotation, thereby utilizing the various connecting rods described above to drive the coil plate 212 toward or away from the drive shaft 211.

[0038] It should be noted that the specific structure of the connecting bearing 213 includes an inner ring 2132, an outer ring 2131 and balls 2133. The inner ring 2132 has a connecting portion formed along its own axial direction that is connected to the fixing nut 214. The outer ring 2131 is sleeved on the outer periphery of the inner ring 2132, and an annular groove for accommodating the inner ring 2132 is opened on the inner side of the outer ring 2131. The end faces of the inner ring 2132 are respectively rollingly connected with the corresponding inner side walls of the annular groove through the balls 2133. Therefore, during the rotation and axial movement of the fixing nut 214 in this embodiment, the inner ring 2132 and the outer ring 2131 are always rollingly connected, thereby driving the axial movement of the connecting sleeve 23 mentioned above.

[0039] Based on the above embodiment, a feasible implementation method is proposed. Specifically, a locking through hole is provided on the outer periphery of the fixing nut 214, an internal thread is provided on the inner wall of the locking through hole, and a positioning bolt 2141 is screwed into the locking through hole so that the rotation of the fixing nut 214 is locked by tightening the positioning bolt 2141 to prevent the fixing nut 214 from loosening during the rotation of the drive shaft 211.

[0040] In addition to the above-mentioned feasible embodiments, in a possible implementation, a connecting plate is provided on the outer periphery of the connecting sleeve 23, the length direction of the connecting plate extends along the axial direction of the connecting sleeve 23, and the width direction of the connecting plate extends along the radial direction of the connecting sleeve 23. The first hinge shaft and the fourth hinge shaft are both connected to the connecting plate to form a stable connection between the two connecting rods and the connecting sleeve 23 through the first hinge shaft and the second hinge shaft.

[0041] Based on the same inventive concept, the present invention also proposes a pipe production line, which includes the weld burr processing equipment mentioned above.

[0042] Compared with the prior art, the pipe production line in the present invention has all the benefits of the above-mentioned weld burr processing equipment, which will not be repeated here.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
