Description

Technical Field

[0001] The present invention belongs to the technical field of pipe chamfering, and specifically relates to a pipe fitting chamfering device. Background Art

[0002] Furniture refers to a large category of essential utensils and facilities for humans to maintain normal life, engage in production practices, and carry out social activities. Furniture has also been continuously developed and innovated with the pace of the times. Nowadays, it has a wide variety of categories, different materials, complete varieties, and different uses. It is an important foundation for establishing a working and living space. Pipes are materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of the pipes directly determines the quality of the pipe fittings. Such pipes are widely used in construction projects, power plants, chemical plants, etc. Chamfering devices can perform 45-degree bevel or polygon cutting and are suitable for cross-stitch picture frames, oil painting frames, wooden strips, etc.

[0003] A patent with the publication number CN112060181A discloses a new type of pipe chamfering device for furniture production, which includes a chamfering device, a conveying device, a clamping mechanism, and a chamfering component. The conveying device is arranged on the left frame of the chamfering device. The clamping mechanism is arranged on the right side of the conveying device. A detection device is installed above the clamping mechanism. A chamfering component is also arranged on the right side of the clamping mechanism. The pipe enters the clamping mechanism through the track in the conveying device. At the same time, the shape of the pipe is detected by the detection device, then it enters the clamping mechanism and is gradually clamped and fixed, and is conveyed, and then chamfered by the chamfering component.

[0004] In the current prior art, when cutting existing pipes, some pipes need to be cut at a 45° angle. During cutting, due to different frictions, burrs and debris will appear at the cutting edge of the pipe. After cutting, the pipes need to be manually polished later. However, due to different forces during manual polishing, depressions will appear on the surface of the pipes, resulting in uneven thickness at the pipe cut.

[0005] Therefore, the present invention provides a pipe fitting chamfering device. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

A pipe is movably sleeved on the outer surface of the metal cutting and grinding table. A motor I is fixedly installed on the top surface of the metal cutting table. A metal cutter is fixedly installed on the output end of the motor I. A drainage sleeve is arranged on the top surface of the metal cutting table. On the outer surface of the top of the metal cutting and grinding table, a fourth motor is provided. On the outer surface of the output end of the metal cutting and grinding table, a protective sleeve and a limiting column are respectively and fixedly installed. On the inner wall surface of the protective sleeve and the outer surface of the limiting column, an elastic wire and a swing arm are respectively and fixedly connected.

The outer surfaces of the two groups of grinding strips are respectively movably lapped on the inner and outer surfaces of the pipe.

[0008] Preferably, limiting strips are provided on the inner wall surfaces on both sides of the metal cutting and grinding table. On one inner wall surface of the metal cutting and grinding table, a third motor is fixedly installed. On the output end of the third motor, a threaded rod is fixedly connected.

[0009] Preferably, a slider arranged on the outer surface of the limiting strip is threadedly and movably sleeved on the outer surface of the threaded rod. The outer surface of the fourth motor is fixedly installed on the top surface of the slider.

[0010] Preferably, a support column is fixedly installed on one surface of the metal cutting table. On the outer surface of the support column, a lifting and peeling arm is fixedly installed.

[0011] Preferably, a second motor is fixedly installed on the top surface of the support column. On the output end of the second motor, a swing cutting table is fixedly connected. On the top surface of the swing cutting table, a plurality of semi-circular grooves are formed.

[0012] Preferably, the outer surface of the pipe is movably sleeved on the inner wall surface of the semi-circular groove. On the top surface of the swing cutting table and at the top two side edge positions of the semi-circular groove, elastic limiting strips are fixedly connected.

[0013] Preferably, a C-shaped support frame is fixedly connected to the outer surface of the support column. The inner wall surface of the C-shaped support frame is sleeved on the outer surface of the swing cutting table. On the outer surface of the C-shaped support frame, a water tank is fixedly installed. On the inner wall surface of the C-shaped support frame, a C-shaped flushing plate is fixedly installed. The inside of the C-shaped flushing plate is arranged on the outer surface of the pipe.

[0014] Preferably, a lapping plate is fixedly connected to one end of the C-shaped support frame. On the bottom surface of the lapping plate, a limiting groove is formed. The inner wall surface of the limiting groove is movably lapped on the outer surface of the pipe. On the top surface of the lapping plate and at one side edge position, a peeling groove is formed.

[0015] Preferably, a limiting sleeve is fixedly installed on the outer surface of the lapping plate. On the bottom two inner wall surfaces of the limiting sleeve, limiting soft strips are fixedly connected. On the top surface of the limiting sleeve, a support plate is fixedly installed.

[0016] Preferably, a hydraulic rod is fixedly installed on the bottom surface of the support plate. The output end of the hydraulic rod is fixedly connected with a semi-circular lower pressing plate. The outer surface of the pipe is movably sleeved inside the limiting sleeve, and the inner wall surface of the semi-circular lower pressing plate is movably lapped on the top surface of the pipe.

[0017] The beneficial effects of the present invention are as follows: 1. For a pipe fitting chamfering device of the present invention, after one end of the pipe is cut, the protective sleeve on the output end of the motor four and the grinding strips on the inner wall surface are respectively attached to the inner and outer surfaces of the pipe. As the pipe gradually penetrates, the pipe will cause the grinding strips to swing and deform, so that the grinding strips can greatly fit on the inner and outer surfaces of the pipe. At the same time, with the elastic wire elastically pushing one end of the grinding strip, the grinding strip rotates around the swing arm as the axis point, and the surface of the grinding strip can greatly fit at the cutting opening of the pipe. Under the rotation of the grinding strip, the grinding strip quickly grinds and polishes the cutting opening of the pipe; 2. For a pipe fitting chamfering device of the present invention, the employee is assisted to sleeve the pipe into the limiting sleeve, and the position of the bottom surface of the pipe is limited by the limiting soft strip, so that the pipe is in a horizontal state and its position is limited. At this time, the hydraulic rod on the inner wall surface of the support plate presses down the semi-circular lower pressing plate, so that the pipe is peeled off from the inside of the limiting sleeve in a vertical state, and the pipe is clamped into the semi-circular groove, and the position of the pipe is limited by the elastic limiting strip, and the position, angle and exposed length of the pipe are controlled by the elastic limiting strip; 3. For a pipe fitting chamfering device of the present invention, when the pipe is clamped into the semi-circular groove, the motor two rotates the swing cutting table, and the pipe is transferred at the bottom edge position of the overlapping plate. At this time, with the bottom surface of the overlapping plate attached to the top edge position of the pipe, it can greatly prevent the pipe from tilting when moving; 4. For a pipe fitting chamfering device of the present invention, with the continuous rotation of the swing cutting table, one end of the pipe will cross over the top surface of the lifting and peeling arm. At this time, using the inclined surface on the top surface of the lifting and peeling arm, the pipe rises higher and higher along the inclined surface of the lifting and peeling arm, so as to tilt one end of the pipe upward, so that the pipe is peeled off from the elastic limiting strip, which is convenient for the subsequent employee to take one end of the pipe; 5. For the pipe fitting chamfering device of the present invention, after one end of the pipe is cut and polished, under the rotation of the swing cutting table, the cutting port of the pipe will cross from the inside of the C-shaped flushing plate. At this time, the water tank is used to pour water into the inside of the C-shaped flushing plate, so that the water source is sprayed at the cutting port of the pipe, washing down some residual debris, and at the same time cooling the cutting port of the pipe.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 7 shown, a pipe fitting chamfering device according to an embodiment of the present invention includes a metal cutting table 11 and a metal cutting and grinding table 15 fixedly installed on the outer surface of the top of the metal cutting table 11, a pipe 14 movably sleeved on the outer surface of the metal cutting and grinding table 15, a first motor 112 fixedly installed on the top surface of the metal cutting table 11, a metal cutter 113 fixedly installed on the output end of the first motor 112, and a drainage sleeve 111 provided on the top surface of the metal cutting table 11; A fourth motor 155 is provided on the outer surface of the top of the metal cutting and grinding table 15, a protective sleeve 159 and a limiting column are respectively fixedly installed on the outer surface of the output end of the metal cutting and grinding table 15, an elastic wire 157 and a swing arm 156 are respectively fixedly connected to the inner wall surface of the protective sleeve 159 and the outer surface of the limiting column, a grinding strip 158 is swingably connected to the other end of the swing arm 156, the other end of the elastic wire 157 is fixedly connected to the outer surface of the grinding strip 158, and the outer surfaces of the two groups of grinding strips 158 are respectively movably lapped on the inner and outer surfaces of the pipe 14.

[0023] When the pipe 14 moves to the output end of the metal cutter 113, the first motor 112 is cooperated to swing the metal cutter 113, so that the metal cutter 113 performs metal cutting on one end of the pipe 14 at a 45° inclination angle. The metal corners cut off will be diverted into the metal cutting table 11 through the drainage sleeve 111 for recycling; After one end of the pipe 14 is cut, the protective sleeve 159 on the output end of the fourth motor 155 and the grinding strip 158 on the inner wall surface are respectively attached to the inner and outer surfaces of the pipe 14. As the pipe 14 gradually penetrates, the pipe 14 will swing and deform the grinding strip 158, so that the grinding strip 158 can fit well on the inner and outer surfaces of the pipe 14. At the same time, the elastic wire 157 is cooperated to elastically push one end of the grinding strip 158, so that the grinding strip 158 rotates around the swing arm 156 as the axis point. The surface of the grinding strip 158 can fit well at the cutting port of the pipe 14, and under the rotation of the grinding strip 158, the grinding strip 158 performs rapid grinding and polishing on the cutting port of the pipe 14.

[0024] As Figures 1 to 7As shown, limiting strips 151 are provided on the inner wall surfaces on both sides of the metal cutting and grinding table 15. A third motor 152 is fixedly installed on one inner wall surface of the metal cutting and grinding table 15. A threaded rod 153 is fixedly connected to the output end of the third motor 152. A slider 154 is threadedly movably sleeved on the outer surface of the threaded rod 153 and is arranged on the outer surface of the limiting strip 151. The outer surface of the fourth motor 155 is fixedly installed on the top surface of the slider 154.

[0025] After the pipe 14 is cut, the third motor 152 is rotated to drive the threaded rod 153. Under the limitation of the limiting strip 151, the slider 154 moves on the surface of the threaded rod 153, and the protective sleeve 159 at one end of the fourth motor 155 is sleeved on the outer surface of the pipe 14. Under the rotation of the fourth motor 155, the cutting port of the pipe 14 is polished. At the same time, with the continuous penetration of the slider 154, the effect of effectively polishing some deep parts is achieved.

[0026] As Figures 1 - 3 and Figures 8 to 10 As shown, a support column 12 is fixedly installed on one surface of the metal cutting table 11. A lifting and peeling arm 121 is fixedly installed on the outer surface of the support column 12. A second motor 122 is fixedly installed on the top surface of the support column 12. A swinging cutting table 123 is fixedly connected to the output end of the second motor 122. A plurality of semi-circular grooves 124 are formed on the top surface of the swinging cutting table 123. The outer surface of the pipe 14 is movably sleeved on the inner wall surface of the semi-circular groove 124. Elastic limiting strips 125 are fixedly connected to the top surface of the swinging cutting table 123 and are located at the top two side edge positions of the semi-circular groove 124. A C-shaped support frame 13 is fixedly connected to the outer surface of the support column 12, and the inner wall surface of the C-shaped support frame 13 is sleeved on the outer surface of the swing cutting table 123. A water tank 131 is fixedly installed on the outer surface of the C-shaped support frame 13, and a C-shaped flushing plate 132 is fixedly installed on the inner wall surface of the C-shaped support frame 13. The interior of the C-shaped flushing plate 132 is arranged on the outer surface of the pipe 14. A lap plate 133 is fixedly connected to one end of the C-shaped support frame 13, and a limiting groove 135 is provided on the bottom surface of the lap plate 133. The inner wall surface of the limiting groove 135 is movably overlapped on the outer surface of the pipe 14. A stripping groove 134 is provided on the top surface and at the edge of one side, a limiting sleeve 136 is fixedly installed on the outer surface of the overlapping plate 133, and a limiting soft strip 137 is fixedly connected to the inner wall surfaces on both sides of the bottom of the limiting sleeve 136, a support plate 138 is fixedly installed on the top surface of the limiting sleeve 136, a hydraulic rod 139 is fixedly installed on the bottom surface of the support plate 138, and a semicircular lower pressure plate 1310 is fixedly connected to the output end of the hydraulic rod 139, the outer surface of the pipe 14 is movably sleeved on the inside of the limiting sleeve 136, and the inner wall surface of the semicircular lower pressure plate 1310 is movably overlapped on the top surface of the pipe 14.

[0027] Cooperate with the staff to sleeve the pipe 14 into the limiting sleeve 136, and cooperate with the limiting soft strip 137 to limit the position of the bottom surface of the pipe 14, so that the pipe 14 is in a horizontal state and its position is limited. At this time, the hydraulic rod 139 on the inner wall of the support plate 138 presses down the semicircular lower pressure plate 1310, so that the pipe 14 is peeled off from the inside of the limiting sleeve 136 in a vertical state, so that the pipe 14 is clamped into the inside of the semicircular groove 124, and the position of the pipe 14 is limited by the elastic limiting strip 125, and the position, angle and exposed length of the pipe 14 are controlled by the elastic limiting strip 125; When the pipe 14 is inserted into the semicircular groove 124, the motor 2 122 is used to rotate the swing cutting table 123, and the pipe 14 is transferred to the bottom edge of the lap plate 133. At this time, the bottom surface of the lap plate 133 is attached to the top edge of the pipe 14, which can greatly avoid the pipe 14 from being blocked when it is lifted during movement. After one end of the pipe 14 is cut and polished, the cut end of the pipe 14 will pass through the inside of the C-shaped flushing plate 132 under the rotation of the swing cutting table 123. At this time, the water source is poured into the inside of the C-shaped flushing plate 132 in cooperation with the water tank 131, so that the water source is sprayed on the cut end of the pipe 14 to clean some residual debris and cool the cut end of the pipe 14 at the same time. With the continuous rotation of the swinging cutting table 123, one end of the pipe 14 will cross over the top surface of the lifting and peeling arm 121. At this time, by using the inclined surface on the top surface of the lifting and peeling arm 121, the pipe 14 will rise higher and higher along with the inclined surface of the lifting and peeling arm 121, thereby tilting one end of the pipe 14 upward and peeling the pipe 14 out of the inside of the elastic limit strip 125, facilitating the subsequent handling of taking one end of the pipe 14 by the staff.

[0028] Working principle: The pipe 14 is sleeved into the inside of the limit sleeve 136, and the position of the pipe 14 is limited by the cooperation of the limit soft strip 137, so that the pipe 14 is in a horizontal state and its position is limited. At this time, the hydraulic rod 139 on the inner side wall of the support plate 138 presses down the semi-circular lower pressing plate 1310, so that the pipe 14 is peeled off from the inside of the limit sleeve 136 in a vertical state. When the pipe 14 is clamped into the inside of the semi-circular groove 124, the position of the pipe 14 is limited by the elastic limit strip 125, and the effect of controlling the position, angle and exposed length of the pipe 14 by the elastic limit strip 125 is achieved; When the pipe 14 is clamped into the semi-circular groove 124, the motor two 122 is used to rotate the swinging cutting table 123, and the pipe 14 is transferred at the bottom edge position of the overlapping plate 133. At this time, the bottom surface of the overlapping plate 133 is fitted to the top edge position of the pipe 14, which can greatly prevent the pipe 14 from tilting when moving; When the pipe 14 moves to the output end of the metal cutting tool 113, the motor one 112 is used to swing the metal cutting tool 113, so that the metal cutting tool 113 performs metal cutting on one end of the pipe 14 at a 45° inclination angle. The cut metal corners will be guided into the metal cutting table 11 through the diversion sleeve 111 for recycling; After one end of the pipe 14 is cut, the protective sleeve 159 on the output end of the motor four 155 and the grinding strip 158 on the inner side wall are respectively fitted to the inner and outer surfaces of the pipe 14. As the pipe 14 gradually penetrates, the pipe 14 will swing and deform the grinding strip 158, so that the grinding strip 158 can greatly fit the inner and outer surfaces of the pipe 14. At the same time, the elastic wire 157 elastically pushes one end of the grinding strip 158, so that the grinding strip 158 rotates around the swing arm 156 as the axis point. The surface of the grinding strip 158 can greatly fit the cutting port of the pipe 14, and under the rotation of the grinding strip 158, the grinding strip 158 quickly grinds and polishes the cutting port of the pipe 14; After one end of the pipe 14 is cut and polished, under the rotation of the swing cutting table 123, the cutting port of the pipe 14 will cross from the inside of the C-shaped flushing plate 132. At this time, the water tank 131 is used to pour water into the inside of the C-shaped flushing plate 132, so that the water source is sprayed at the cutting port of the pipe 14, washing down some residual debris, and at the same time cooling the cutting port of the pipe 14; With the continuous rotation of the swing cutting table 123, one end of the pipe 14 will cross from the top surface of the lifting and peeling arm 121. At this time, using the inclined surface on the top surface of the lifting and peeling arm 121, the pipe 14 will become higher and higher along with the inclined surface of the lifting and peeling arm 121, thereby tilting one end of the pipe 14 upward, so that the pipe 14 is peeled off from the inside of the elastic limit strip 125, facilitating the subsequent handling of the end of the pipe 14 by the staff.
