Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing equipment, in particular to a steel pipe cross-section grinding component. Background Art

[0002] Due to their strong plasticity, high torsional strength, and light weight, steel pipes are widely used in the construction industry as supporting building materials. However, during the production process, steel pipes are long and need to be cut into multiple sections of equal length. After cutting, the cut section of the steel pipe will produce a large number of burrs, and burrs will appear on both the outer and inner edges of the section. These burrs need to be removed using a grinding assembly. However, when fixing the steel pipe, the existing steel pipe section grinding assembly needs to first clamp and limit one end of the steel pipe, and then use a clamping member to fix the other parts of the steel pipe. This fixing operation is relatively cumbersome and the operation efficiency is relatively low.

[0003] Existing patent application number: 202223409177.6 discloses a stainless steel pipe cross-section grinding device. The device uses two limit plates to clamp and limit one end of the steel pipe, and then cooperates with a baffle and two sets of rotating rods to compress and fix other parts of the steel pipe to achieve the steel pipe fixing effect. The spacing between the two limit plates can be adjusted to fix steel pipes of different sizes. In the above-mentioned prior art, the operation of fixing the steel pipe before grinding the steel pipe cross-section still has the above-mentioned technical problems. Utility Model Content

[0004] The purpose of the present invention is to provide a steel pipe cross-section grinding assembly to solve the problems in the above-mentioned background technology that the fixing operation process is relatively complicated and the operation efficiency is relatively low.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a steel pipe cross-section grinding assembly, comprising a support box and two limiting half rings relatively fixed to the top of the support box, and the steel pipe cross-section grinding assembly also includes:

[0007] A movable strap is connected to and inserted into the strip groove provided on the top of the support box.

[0008] Two movable seats are arranged opposite to each other in the supporting box.

[0009] A driving part is used to drive the two movable seats to move closer to or away from each other.

[0010] The driving wheel arranged on the top of the movable seat is rotated, and the outer portion of the driving wheel is sleeved in the movable strap. When the steel pipe is inserted into the movable strap, the two movable seats are driven away from each other by the driving part, so that the movable strap is tightened between the two driving wheels and the outer portion of the steel pipe.

[0011] A servo motor is used to drive one of the driving wheels to rotate, so that after the movable strap is tightened, the driving wheel drives the steel pipe to rotate through the movable strap.

[0012] Furthermore, the limiting half rings are both semicircular, and the two limiting half rings are coaxial.

[0013] Furthermore, the strip groove is located between the two limiting half rings, and a protrusion is provided in the strip groove for preventing the movable strap from falling into the supporting box.

[0014] Furthermore, the steel pipe section grinding assembly also includes:

[0015] A supporting platform is arranged on the top of the supporting box.

[0016] A lifting part is used to drive the supporting platform to move up and down.

[0017] A double-head grinder is arranged on the top of the supporting platform.

[0018] A conical grinding head is detachably mounted on the output end of the double-head grinder, and is used for grinding and removing burrs on the cross section of the steel pipe.

[0019] Furthermore, the two conical grinding heads are symmetrically distributed on the double-head grinder, and the opposite surfaces of the two conical grinding heads form a V-shaped grinding area.

[0020] Furthermore, the steel pipe section grinding assembly also includes:

[0021] A reserved groove is provided on the top of the supporting box, and the top of the lifting part is inserted into the reserved groove.

[0022] Furthermore, one of the limiting half rings is located between the strip groove and the reserved groove, and the axes of the two conical grinding heads and the axis of the limiting half ring are in a coplanar relationship.

[0023] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:

[0024] 1. The utility model utilizes two coaxially arranged limiting half-rings and a movable band disposed between the two limiting half-rings. The steel pipe can be fixed by simply placing the steel pipe axially within the two limiting half-rings and passing it through the movable band. The servo motor then directly drives the two movable seats away from each other and tightens the movable band. This reduces the difficulty and steps involved in the steel pipe fixing operation and improves its efficiency.

[0025] 2. The utility model uses a movable strap, two movable seats, two driving wheels and two limiting semi-rings in coordination with each other. After fixing the steel pipe, the driving wheel can be directly driven by a servo motor to rotate, thereby driving the movable strap to rotate. The circumferential friction between the movable strap and the steel pipe can be used to drive the steel pipe to rotate. In conjunction with the V-shaped grinding area between the two upper and lower parallel conical grinding heads, the boundary of the steel pipe section can be placed in the V-shaped grinding area, so as to achieve synchronous grinding of the inner and outer edges of the boundary of the steel pipe section, thereby improving the efficiency of deburring the steel pipe section.

[0030] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0031] like Figures 1 to 3 As shown, a steel pipe cross-section grinding assembly includes a support box 1 and two limiting half rings 2 relatively fixed to the top of the support box 1. The steel pipe cross-section grinding assembly also includes:

[0032] A movable strap 8 is inserted and connected with the strip groove 3 provided on the top of the support box 1.

[0033] Two movable seats 4 are arranged opposite to each other in the supporting box 1 .

[0034] The driving part 5 is used to drive the two movable seats 4 to move closer to or away from each other. The driving part 5 includes a screw rod rotatably arranged in the support box 1. The two ends of the screw rod are respectively threaded on the two movable seats 4, and the thread directions of the two ends of the screw rod are opposite.

[0035] The driving wheel 6 located on the top of the movable seat 4 is rotated, and the outer portion of the driving wheel 6 is sleeved in the movable strap 8. When the steel pipe is inserted into the movable strap 8, the two movable seats 4 are driven away from each other by the driving part 5, so that the movable strap 8 is tightened between the two driving wheels 6 and the outer portion of the steel pipe.

[0036] The servo motor 7 is used to drive one of the driving wheels 6 to rotate. After the movable strap 8 is tightened, the driving wheel 6 drives the steel pipe to rotate through the movable strap 8.

[0037] When fixing the steel pipe, it is only necessary to place the steel pipe axially in the two limiting half rings 2 and pass it through the inside of the movable band 8. Then, the driving unit 5 drives the two movable seats 4 away from each other and tightens the movable band 8 to complete the fixing operation of the steel pipe, reducing the difficulty and steps of the steel pipe fixing operation and improving the efficiency of the steel pipe fixing operation. After fixing the steel pipe, the servo motor 7 directly drives the driving wheel 6 to rotate, thereby driving the movable band 8 to rotate. The circumferential friction between the movable band 8 and the steel pipe can be used to drive the steel pipe to rotate, so as to facilitate comprehensive grinding of the inner and outer edges of the steel pipe section.

[0038] In this embodiment, the limiting half rings 2 are both semicircular, and the two limiting half rings 2 are coaxial. Such a design can enable the movable strap 8 to cooperate with the two limiting half rings 2, and the steel pipe is fixed between the two limiting half rings 2 by tightening the movable strap 8, thereby avoiding the problem of lateral displacement of the steel pipe position when the movable strap 8 drives the steel pipe to rotate during the later grinding, thereby affecting the normal progress of the grinding operation.

[0039] In this embodiment, the strip groove 3 is located between the two limiting semi-rings 2, and a protrusion is provided in the strip groove 3 for preventing the movable strap 8 from falling into the support box 1. With this design, the movable strap 8 in a relaxed state can be effectively prevented from falling into the support box 1 under the obstruction of the protrusion, thereby increasing the difficulty of the steel pipe fixing operation and facilitating the user to pass the steel pipe through the movable strap 8. At the same time, the limiting semi-rings 2 on both sides of the outside of the movable strap 8 are used in conjunction to improve the fixing effect of the steel pipe, thereby preventing the steel pipe from being offset or shaking during the grinding process, thereby affecting the normal grinding of the steel pipe section.

[0040] In this embodiment, the steel pipe section grinding assembly further includes:

[0041] A supporting platform 11 is provided on the top of the supporting box 1 .

[0042] The lifting unit 10 is used to drive the supporting platform 11 to move up and down.

[0043] A double-headed grinder 12 is provided on top of the supporting platform 11 .

[0044] The conical grinding head 13 is detachably mounted on the output end of the double-headed grinding machine 12 and is used for grinding and removing burrs on the cross section of the steel pipe.

[0045] The two conical grinding heads 13 are symmetrically distributed on the double-head grinder 12 , and the opposite surfaces of the two conical grinding heads 13 form a V-shaped grinding area.

[0046] By cooperating with structures such as the movable strap 8, two movable seats 4, two driving wheels 6 and two limiting semi-rings 2, after fixing the steel pipe, the driving wheel 6 can be directly driven by the servo motor to rotate, thereby driving the movable strap 8 to rotate. The circumferential friction between the movable strap 8 and the steel pipe can be used to drive the steel pipe to rotate. In conjunction with the V-shaped grinding area between the two upper and lower parallel conical grinding heads 13, the boundary of the steel pipe section can be placed in the V-shaped grinding area, so as to achieve synchronous grinding of the inner and outer edges of the boundary of the steel pipe section, thereby improving the efficiency of deburring the steel pipe section.

[0047] In this embodiment, the steel pipe section grinding assembly further includes:

[0048] A reserved slot 9 is provided at the top of the support box 1, and the top of the lifting part 10 is inserted into the reserved slot 9. The lifting part 10 includes:

[0049] The two support arms are hinged relative to each other at the bottom of the supporting platform 11 .

[0050] The two support legs are hinged relative to each other in the support box 1.

[0051] A nut seat is provided between the support leg and the support arm.

[0052] The transverse thread is sleeved on the adjusting screw between the two nut seats.

[0053] The two support arms are arranged in an outward-facing "X" shape at the bottom of the support platform 11, and the two support legs are arranged in an inverted "X" shape in the support box 1. By rotating the adjustment screw, the two nut seats can be driven closer to or away from each other, thereby adjusting the height of the support platform 11 to facilitate adjusting the height of the V-shaped grinding area so that it can be aligned with the inner and outer edges of steel pipe sections of different diameters, thereby improving its scope of application.

[0054] In this embodiment, one of the limiting half rings 2 is located between the strip groove 3 and the reserved groove 9 , and the axes of the two conical grinding heads 13 and the axis of the limiting half ring 2 are coplanar.

[0055] Working principle: Before grinding the steel pipe, first pass the steel pipe horizontally through the limiting half ring 2 away from the double-head grinder 12, and then pass through the movable strap 8 and the inside of the remaining limiting half ring 2 in turn, and then control the lifting part 10 to adjust the height of the double-head grinder 12, so that the V-shaped grinding area between the conical grinding heads 13 at the two output ends of the double-head grinder 12 is aligned with the inner and outer edges of the top of the steel pipe section, and then make the inner and outer edges of the steel pipe section contact with the V-shaped grinding area, and make the inner and outer edges contact with the grinding surfaces of the two conical grinding heads 13 respectively, and then control the driving part 5 to drive the two movable seats 4 and the two driving parts. The wheels 6 are away from each other, so that the movable band 8 is tightened and sleeved on the outside of the steel pipe, thereby realizing the fixing operation of the steel pipe and the alignment operation of the grinding position of the steel pipe section. The operation steps are simple and efficient. Then the double-head grinder 12 and the servo motor 7 are started at the same time. The output end of the servo motor 7 directly drives one of the driving wheels 6 to rotate, and the driving wheel 6 drives the tightened movable band 8 to rotate. Through the friction between the movable band 8 and the surface of the steel pipe, the steel pipe is driven to rotate slowly, thereby realizing comprehensive grinding of the inner and outer edges of the steel pipe section and removing burrs on the inner and outer edges of the steel pipe section, thereby improving the efficiency of removing burrs on the steel pipe section.
