Description

Technical Field

[0001] The utility model relates to the technical field of steel groove cutting, in particular to an intelligent long-side groove opening device. Background Art

[0002] Before welding steel (such as H-beam), the edge of the steel needs to be grooved (refers to the groove of a certain geometric shape that is processed and assembled at the welded part of the weldment) to ensure the weldability. Because it is used for welding steel, the processing requirements are not high and can be processed by gas welding cutting.

[0003] At present, there are many gas welding devices for cutting grooves, such as a Chinese patent with patent publication number CN1138675A, which discloses a process of welding or cutting metal with liquefied petroleum gas. It uses a traditional suction welding (cutting) torch and uses liquefied petroleum gas to replace traditional acetylene gas, and mixes with oxygen to burn, generating high temperature to melt the metal, and finally achieves the purpose of welding and cutting metal. Practice has proved that it can fully meet production requirements, is not only simple to operate, safe to use, and has no environmental pollution, but also has a very low price, greatly reduces production costs, and has a wide range of use and promotion value.

[0004] When using the gas welding device shown in the above patent drawings, the worker needs to hold the welding gun and aim it at the part that needs to be cut in order to achieve the cutting requirement. For steel plates that are more than ten meters long, if the worker maintains a certain state for a long time and moves the welding gun along the length of the steel plate to cut it, it will cause discomfort to the worker. If the worker cuts intermittently, it will affect the cutting efficiency of the steel. In addition, the manual holding of the welding gun has low precision and is very likely to bend the cutting, which is not conducive to the welding of steel.

[0005] There are also intelligent, large-sized, fixed-setting gas welding and cutting equipment on the market. Compared with steel plates that are more than ten meters long, it is inconvenient to perform bevel cutting on steel materials because the steel materials are long and heavy. If they are used to perform bevel cutting on steel materials, it is inconvenient to control the movement of the steel materials and adjust the state of the steel materials according to demand.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0029] like Figure 1-8 As shown, an intelligent long-side beveling device includes a welding gun 3, an oxygen cylinder and an acetylene cylinder. The oxygen cylinder and the acetylene cylinder are placed on a cart and connected to the welding gun 3 through a pipeline. In order to ensure safe work, a pressure reducer is also required. The pressure reducer is arranged between the welding gun 3 and the gas cylinder. When the device is used to bevel steel, the staff can hold the welding gun 3 and move the welding gun 3 along the length direction of the steel. By igniting the gas, the steel is cut. At the same time, the staff also needs to push the cart to adjust the position of the oxygen cylinder and the acetylene cylinder according to the progress of the bevel cutting, so as to facilitate the bevel cutting of the steel. The above-mentioned gas welding and cutting is a prior art, so it will not be described in detail here.

[0030] Although the above-mentioned gas welding and cutting device can perform bevel cutting on the edge of steel, as recorded in the background technology, it still has some problems. For example, it requires workers to hold it for a long time to complete the bevel cutting of longer steel, or it is inconvenient to adjust the state of the steel when the smart and fixed setting on the gas welding device is cutting longer steel. In order to solve these problems, it is necessary to improve the gas welding and cutting device recorded in the first paragraph above.

[0031] Specifically, a support pipe 31 can be sleeved outside the welding torch 3. The support pipe 31 is adjustably arranged at the end of the cross plate 5. The other end of the cross plate 5 is adjustably provided with a frame body 1. Two edges below the frame body 1 are respectively provided with a roller 13 and a traveling mechanism 4. The frame body 1 is arranged in a U-shaped structure. The roller 13 and the driving wheel 41 of the traveling mechanism 4 are both arranged along the length direction of the steel and the frame body 1. In addition, by rotating the driving wheel 41, the frame body 1 can be controlled to move along the length direction of the steel. At this time, both the frame body 1 and the welding torch 3 are located above the steel, and the welding torch 3 is controlled to be stably placed relative to the frame body 1. Then, the welding torch 3 can be controlled to move along the length direction of the steel under the movement of the frame body 1. During the movement of the welding torch 3, the ignited gas realizes the cutting of the edge of the steel. Since the support pipe 31 and the cross plate 5 are adjustably arranged, the inclination angle and height of the welding torch 3 can be adjusted according to the requirements of gas welding and cutting, providing support for completing different gas welding and cutting tasks. When the traveling mechanism 4 is replaced by the roller 13, the device can be pushed by the staff to move to complete the cutting treatment of the groove.

[0032] To realize the adjustable setting of the support pipe 31, a notch 54 is provided at the end of the cross plate 5. An installation groove 55 is provided on the side wall of the notch 54. A filling plate 51 is detachably arranged at the installation groove 55 through bolts. The support pipe 31 is arranged through the notch 54. The end shaft 32 is inserted into the space formed by the filling plate 51 and the installation groove 55. Under the action of the end shaft 32, the support pipe 31 can be rotatably arranged around the shaft group at the notch 54. The detachable setting of the filling plate 51 provides convenience for quickly disassembling and assembling the support pipe 31 according to requirements. At the same time, a through-type lead screw stepping motor is hinged above the cross plate 5. A third threaded rod 53 is threaded through the through-type lead screw stepping motor. The end of the third threaded rod 53 is hinged with the support pipe 31. Under the operation of the through-type lead screw stepping motor, the third threaded rod 53 can be controlled to move relative to the cross plate 5, and then drive the support pipe 31 to rotate around the axis, realizing the adjustment of the inclination angle of the welding torch 3 and making the adjusted welding torch 3 stably placed relative to the cross plate 5, providing convenience for better completing the gas welding and cutting of the steel.

[0033] To make the welding torch 3 stably placed relative to the support pipe 31, the inner diameter of the support pipe 31 is larger than the diameter of the welding torch 3, and an end shaft 32 is arranged on the outside. A limiting tapered pipe 33 is arranged above the support pipe 31. The lower end of the limiting tapered pipe 33 extends into the gap between the support pipe 31 and the welding torch 3. Under the extrusion of the limiting tapered pipe 33, the resistance of the welding torch 3 moving relative to the support pipe 31 is increased, making the welding torch 3 stably placed relative to the support pipe 31. In addition, when the welding torch 3 and the support pipe 31 need to be disassembled, the limiting tapered pipe 33 can be pulled to make it脱离, thereby解除 the limitation between the welding torch 3 and the support pipe 31.

[0034] In order to achieve the adjustability of the cross plate 5, two vertical plates 11 are symmetrically arranged above the frame 1, and a first threaded rod 12 is arranged between the two vertical plates 11. The lower end of the first threaded rod 12 passes through the frame 1 and is connected to the output shaft of the motor. An end block 52 is fixedly arranged at the end of the cross plate 5 away from the support tube 31. The cross section of the end block 52 is the same as the cross section of the space formed by the two vertical plates 11. The end block 52 is located between the two vertical plates 11, and the first threaded rod 12 is threadedly arranged to pass through the end block 52. With the cooperation of the end block 52 and the vertical plates 11, the cross plate 5 can be stably set above the frame 1. In addition, under the operation of the motor, the first threaded rod 12 rotates and forces the cross plate 5 to rise and fall, while adjusting the height of the support tube 31 to provide support for adjusting the height of the welding gun 3.

[0035] In order to force the device to move along the length direction of the steel, the walking mechanism 4 includes a coaxial shaft 42, a driving gear 44, a driven gear 43 and two power wheels 41. The two power wheels 41 are respectively arranged at both ends of the coaxial shaft 42, and the driven gear 43 is sleeved on the coaxial shaft 42. The driving gear 44 is meshingly arranged on the side of the driven gear 43 and sleeved on the output shaft of the motor. The motor controls the driving gear 44 to rotate, drives the driven gear 43 to rotate, and then controls the coaxial shaft 42 to rotate, realizes the rotation of the power wheel 41, and provides support for the frame 1 to drive the welding gun 3 to move along the length direction of the steel.

[0036] In order to realize intelligent gas welding and cutting, the welding gun 3 is set as a GCE fully automatic flame gun, and a touch screen and a PLC are set on the frame 1. The touch screen is used to input instructions and calculate the results to the PLC through the background. Example 2

[0037] like Figure 1-8 As shown, an intelligent long-side beveling device includes a welding gun 3, an oxygen cylinder and an acetylene cylinder. The oxygen cylinder and the acetylene cylinder are placed on a cart and connected to the welding gun 3 through a pipeline. In order to ensure safe work, a pressure reducer is also required. The pressure reducer is arranged between the welding gun 3 and the gas cylinder. When the device is used to bevel steel, the staff can hold the welding gun 3 and move the welding gun 3 along the length direction of the steel. By igniting the gas, the steel is cut. At the same time, the staff also needs to push the cart to adjust the position of the oxygen cylinder and the acetylene cylinder according to the progress of the bevel cutting, so as to facilitate the bevel cutting of the steel. The above-mentioned gas welding and cutting is a prior art, so it will not be described in detail here.

[0038] Although the above gas welding cutting device can perform bevel cutting on the edge of steel, as described in the background art, there are still some problems. For example, it requires workers to hold it for a long time to complete the bevel cutting of long steel, or it is inconvenient to adjust the state of the steel when the intelligent and fixedly set gas welding device cuts long steel. To solve these problems, it is necessary to improve the gas welding cutting device described in the first paragraph above.

[0039] Specifically, a support pipe 31 can be sleeved outside the welding torch 3. The support pipe 31 is adjustably arranged at the end of the cross plate 5. The other end of the cross plate 5 is adjustably provided with a frame body 1. Two edges below the frame body 1 are respectively provided with a roller 13 and a traveling mechanism 4. The frame body 1 is arranged in a U-shaped structure. The roller 13 and the driving wheel 41 of the traveling mechanism 4 are both arranged along the length direction of the steel and the frame body 1. In addition, by rotating the driving wheel 41, the frame body 1 can be controlled to move along the length direction of the steel. At this time, both the frame body 1 and the welding torch 3 are located above the steel, and the welding torch 3 is controlled to be stably placed relative to the frame body 1. Then, the welding torch 3 can be controlled to move along the length direction of the steel under the movement of the frame body 1. During the movement of the welding torch 3, the ignited gas realizes the cutting of the steel edge. Since the support pipe 31 and the cross plate 5 are adjustably arranged, the inclination angle and height of the welding torch 3 can be adjusted according to the gas welding and cutting requirements, providing support for completing different gas welding and cutting tasks. When the traveling mechanism 4 is replaced by the roller 13, the device can be pushed by workers to move to complete the bevel cutting process.

[0040] To realize the adjustable setting of the support pipe 31, a notch 54 is provided at the end of the cross plate 5. An installation groove 55 is provided on the side wall of the notch 54. A filling plate 51 is detachably arranged at the installation groove 55 through bolts. The support pipe 31 is penetrated through the notch 54. The end shaft 32 is inserted into the space formed by the filling plate 51 and the installation groove 55. Under the action of the end shaft 32, the support pipe 31 can be rotatably arranged around the shaft group at the notch 54. The detachable setting of the filling plate 51 provides convenience for quickly disassembling and installing the support pipe 31 according to requirements. At the same time, a through-type lead screw stepping motor is hinged above the cross plate 5. A third threaded rod 53 is threadedly penetrated through the through-type lead screw stepping motor. The end of the third threaded rod 53 is hinged to the support pipe 31. Under the operation of the through-type lead screw stepping motor, the third threaded rod 53 can be controlled to move relative to the cross plate 5, thereby driving the support pipe 31 to rotate around the shaft, realizing the adjustment of the inclination angle of the welding torch 3, and making the adjusted welding torch 3 stably placed relative to the cross plate 5, providing convenience for better completing the gas welding and cutting of steel.

[0041] In order to stably place the welding gun 3 relative to the support tube 31, the inner diameter of the support tube 31 is larger than the diameter of the welding gun 3, and an end shaft 32 is provided on the outside, and a limiting cone tube 33 is provided above the support tube 31, and the lower end of the limiting cone tube 33 extends into the gap between the support tube 31 and the welding gun 3. Under the squeezing of the limiting cone tube 33, the resistance of the welding gun 3 to the movement of the support tube 31 is increased, so that the welding gun 3 is stably placed relative to the support tube 31. In addition, when the welding gun 3 and the support tube 31 need to be disassembled, the limiting cone tube 33 can be pulled out to disengage it, thereby releasing the restriction on the welding gun 3 and the support tube 31.

[0042] In order to achieve the adjustability of the cross plate 5, two vertical plates 11 are symmetrically arranged above the frame 1, and a first threaded rod 12 is arranged between the two vertical plates 11. The lower end of the first threaded rod 12 passes through the frame 1 and is connected to the output shaft of the motor. An end block 52 is fixedly arranged at the end of the cross plate 5 away from the support tube 31. The cross section of the end block 52 is the same as the cross section of the space formed by the two vertical plates 11. The end block 52 is located between the two vertical plates 11, and the first threaded rod 12 is threadedly arranged to pass through the end block 52. With the cooperation of the end block 52 and the vertical plates 11, the cross plate 5 can be stably set above the frame 1. In addition, under the operation of the motor, the first threaded rod 12 rotates and forces the cross plate 5 to rise and fall, while adjusting the height of the support tube 31 to provide support for adjusting the height of the welding gun 3.

[0043] In order to force the device to move along the length direction of the steel, the walking mechanism 4 includes a coaxial shaft 42, a driving gear 44, a driven gear 43 and two power wheels 41. The two power wheels 41 are respectively arranged at both ends of the coaxial shaft 42, and the driven gear 43 is sleeved on the coaxial shaft 42. The driving gear 44 is meshingly arranged on the side of the driven gear 43 and sleeved on the output shaft of the motor. The motor controls the driving gear 44 to rotate, drives the driven gear 43 to rotate, and then controls the coaxial shaft 42 to rotate, realizes the rotation of the power wheel 41, and provides support for the frame 1 to drive the welding gun 3 to move along the length direction of the steel.

[0044] In order to realize intelligent gas welding and cutting, the welding gun 3 is set as a GCE fully automatic flame gun, and a touch screen and a PLC are set on the frame 1. The touch screen is used to input instructions and calculate the results to the PLC through the background.

[0045] like Figure 1 , Figure 2 , Figure 4As shown, in order to limit the movement of the above-mentioned device, snap grooves 14 are provided at both ends of the upper side surface of the frame 1, and a second threaded rod 15 is provided at the snap groove 14. A limiting plate 2 is provided on the side of the frame 1, and the limiting plate 2 is provided as an L-shaped structure. An arc groove 22 is provided at the upper end of the limiting plate 2, and the cross-section of the limiting plate 2 is the same as the cross-section of the snap groove 14. The upper end of the limiting plate 2 is inserted into the snap groove 14, and the second threaded rod 15 is threadedly inserted into the thread groove 21 of the limiting plate 2. Since the cut groove only occupies one edge of the vertical surface, the rest of the vertical surface is relatively smooth. The limiting plate 2 slides in contact with the smooth vertical surface, which can limit the moving direction of the frame 1.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
