Description

Technical Field

[0001] The invention relates to the technical field of plate beveling equipment, and in particular to an anti-gas-break type steel plate beveling machine. Background Art

[0002] Before welding metal plates, the ends of the workpieces to be welded need to be processed into a certain shape. The groove formed after assembly is called a groove. The main purpose of the groove is to achieve complete penetration. In addition, it can also adjust the composition and properties of the weld, improve the crystallization conditions, and improve the performance of the joint.

[0003] Flame cutting is a common way to bevel steel plates in the current market. However, when beveling with a cutting machine, there are the following problems:

[0004] First, the CNC cutting machine and semi-automatic cutting machine cut off the air during the cutting process, thus affecting the cutting quality, which greatly improves the quality of steel plate groove processing;

[0005] Secondly, when most existing cutting equipment cuts plates, the cut surface will form oxide scale due to oxidation under high temperature conditions, which needs to be cleaned manually with tools such as steel brushes and scrapers, which increases the workload and is cumbersome and inconvenient to operate;

[0006] Third, due to its own structure, the existing flame cutting equipment can only cut V-shaped grooves and X-shaped grooves when beveling the plate. For plates with a thickness of 20 to 60 mm, the best beveling shape is a "U"-shaped bevel. This will lead to limitations in the existing flame cutting beveling equipment when beveling large plates. Summary of the invention

[0007] The invention discloses an anti-gas-break type steel plate beveling machine, which aims to solve the technical problems that the existing flame cutting beveling equipment is prone to gas breakage during actual operation, requires manual removal of oxide scale on the cutting surface, and has limitations in the types of bevels that can be cut.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

The beveling wheel further finely grinds the plate on the basis of rough cutting by the cutting machine to produce a "U"-shaped bevel, thereby improving the types of bevels that can be processed by traditional beveling equipment.

[0019] In a preferred solution, the snap-fit ​​assembly includes a double-vent pipe fixedly mounted on the surface of the flap, a latch is slidably mounted inside the double-vent pipe, a slot is provided on the top of one of the adapter rings, and the latch is distributed on the top of the slot.

[0021] As can be seen from the above, the anti-gas-break type steel plate beveling machine provided by the present invention has the following improvements and advantages compared with the prior art:

[0022] Firstly, a plurality of gas collecting bottles connected in series are provided to supply gas for the operation of the cutting machine in turn, thereby ensuring that the cutting machine will not be out of gas during operation, thereby ensuring the stability of the equipment operation; at the same time, the beveling mechanism additionally installed on the side of the cutting machine can drive the two rotating shafts to rotate through a motor on the basis of the rough processing of the plate by the cutting machine, so that the first beveling wheel, the second beveling wheel and the rubber sleeve at the end of the rotating shaft rotate synchronously; the beveling wheel is further finely polished on the basis of the rough cutting of the plate by the cutting machine, thereby producing a special-shaped beveling, thereby increasing the types of beveling that can be processed by traditional beveling equipment; at the same time, the rubber sleeve can scrape the inner wall of the beveling produced by the beveling wheel, thereby wiping off the debris, replacing manual cleaning, thereby greatly improving the functionality and ease of use of the equipment.

It is composed of five parts: several gas collecting bottles, control valves, pressure gauges, tempering valves and pipelines. The gas cylinder group is composed of 2-5 special gas cylinders connected in parallel. A single gas cylinder is connected to the main pipeline through a branch pipeline, and a separate control valve is set. The main pipeline is arranged in sequence from the gas cylinder end.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] The invention discloses an anti-gas-break type steel plate beveling machine which is mainly used in the scenario where flame cutting beveling equipment performs beveling processing on steel plates.

[0041] Reference Figures 1 to 13 , a gas-break-proof steel plate beveling machine, comprising a guide rail 1, a cutting machine table 2 slidably mounted on the top of the guide rail 1, a plurality of gas collecting bottles 3 distributed on the side of the guide rail 1, the gas collecting bottles 3 are connected in series to an air guide pipe 4 and communicate with the cutting machine table 2 through the air guide pipe 4, a mobile machine table 5 is fixed at the end of the guide rail 1, a flap 6 is rotatably mounted on the top of the mobile machine table 5, a beveling mechanism 7 is arranged inside the flap 6, the beveling mechanism 7 comprises a first rotating shaft 701 and a second rotating shaft 702 rotatably mounted inside the flap 6, a belt 703 is connected between the first rotating shaft 701 and the second rotating shaft 702, the belt 703 is distributed inside the flap 6, a motor 704 is installed on the top of the flap 6, the output end of the motor 704 passes through the inside of the flap 6 and is connected to one end of the first rotating shaft 701;

[0042] A switching mechanism 8 is provided inside the groove mechanism 7. The switching mechanism 8 includes a three-way solenoid valve 801 fixed to the surface of the flap 6. A telescopic sleeve 803 is slidably sleeved on the outer sides of the first rotating shaft 701 and the second rotating shaft 702. The three-way solenoid valve 801 is connected through a three-way pipe 802 and two telescopic sleeves 803.

[0043] A processing mechanism 9 is also provided inside the flap 6; the working mode of the groove mechanism 7 is adjusted by the switching mechanism 8, and the special-shaped groove of the plate is completed in coordination with the operation of the cutting machine 2, and the oxide scale on the slope surface is cleaned by the processing mechanism 9.

[0044] In this embodiment: before use, the user connects the gas collecting bottle 3 in series to an air duct 4, and connects the air path with the cutting machine 2 through the air duct 4, and at the same time places the plate to be beveled on the side of the guide rail 1 and starts the entire equipment. The cutting machine 2 will move slowly along the guide rail 1, and at the same time, flame cut the edges and corners of the plate to cut out the prototype of the bevel. The cutting machine 2 will drive the mobile machine 5 while moving. At this time, the beveling mechanism 7 located on the top of the mobile machine 5 is started synchronously, and further polishing is performed on the basis of the prototype of the bevel obtained by cutting the plate by the cutting machine 2, so as to complete the beveling of the plate. At the same time, the processing mechanism 9 is started synchronously and polishes the surface of the bevel to remove the oxide scale generated during cutting; when the user needs to process different bevels, at this time, before the beveling mechanism 7 is operated, the user can start the switching mechanism 8 and change the working mode of the processing mechanism 9 through the switching mechanism 8, so as to process different bevels.

[0045] Among them, it is necessary to supplement the following: an electric push rod 10 is fixedly installed on the top of the mobile machine 5, a sliding groove 11 is provided on the back of the flap 6, and the output end of the electric push rod 10 is slidably connected to the inside of the sliding groove 11. Before the beveling mechanism 7 works, the user can first control the output end of the electric push rod 10 to extend and retract, thereby cooperating with the sliding groove 11 to drive the flap 6, causing the flap 6 to rotate, thereby adjusting the placement angle of the beveling mechanism 7 to facilitate beveling of the plate.

[0046] In the above scheme, considering that for plates with a thickness of 20 to 60 mm, the best type of groove is the "U" type groove, the types of grooves that can be processed by traditional groove equipment need to be increased, and the specific operations are as follows.

[0047] Reference Figures 1 to 5 , Figures 7 and 8In a preferred embodiment, the beveling mechanism 7 also includes a first beveling wheel 705 fixedly installed on the other end of the first rotating shaft 701, a second beveling wheel 706 is slidably sleeved on the outer side of the first rotating shaft 701, the first beveling wheel 705 is hidden inside the second beveling wheel 706, one end of the second rotating shaft 702 is wrapped with a rubber sleeve 707, and the inner wall of the rubber sleeve 707 is fixedly connected to the end of the second rotating shaft 702.

[0048] In this embodiment: the cutting machine 2 will drive the mobile machine 5 while moving. At this time, the motor 704 located on the top of the mobile machine 5 is started synchronously, and the motor 704 drives the first rotating shaft 701 to rotate. The first rotating shaft 701 will drive the second rotating shaft 702 to rotate through the belt 703. At this time, the first beveling wheel 705 located at the end of the first rotating shaft 701 will drive the second beveling wheel 706 to rotate synchronously and further grind on the basis of the beveling prototype obtained by cutting the plate by the cutting machine 2, so as to complete the beveling of the plate, resulting in a "U" shape. At the same time, the rubber sleeve 707 located at the end of the second rotating shaft 702 will rotate synchronously and clean the inside of the beveling finely along with the movement of the mobile machine 5.

[0049] In the above scheme, in order to further improve the types of grooves that can be processed by this equipment, the specific operations are as follows.

[0050] Reference Figures 2 to 9 In a preferred embodiment, the switching mechanism 8 also includes an adapter ring 804 installed at the end of each telescopic sleeve 803, the adapter ring 804 is slidably sleeved on the outside of the first rotating shaft 701 and the second rotating shaft 702 and is rotatably installed with the ends of the second bevel wheel 706 and the rubber sleeve 707 respectively, and a snap-fit ​​assembly 805 is fixedly installed on the surface of the flap 6, and the snap-fit ​​assembly 805 and the adapter ring 804 sleeved on the outside of the first rotating shaft 701 are distributed correspondingly.

[0051] In this embodiment, when the user needs to obtain a groove of other shapes, the user can control the three-way solenoid valve 801 to pump out the air inside the three-way pipe 802 and the two telescopic sleeves 803, so that the telescopic sleeves 803 shrink. When the telescopic sleeves 803 shrink, the second bevel wheel 706 and the rubber sleeve 707 are pulled through the adapter ring 804, so that the first bevel wheel 705 hidden inside the second bevel wheel 706 is exposed (the cutting surface shapes of the second bevel wheel 706 and the first bevel wheel 705 are different, refer to Fig.12), and the rubber sleeve 707 that is pulled will shrink and change its own shape and diameter, accompanied by the rotation of the first beveling wheel 705 and the processing of the "VV combination" bevel, and the rubber sleeve 707 that is deformed synchronously will fit more closely to the inner wall of the bevel and clean the bevel by friction; wherein, a plurality of elastic support members 708 are sleeved on the outer side of the end of the second rotating shaft 702, and the outer side of the elastic support member 708 is squeezed and contacted with the inner wall of the rubber sleeve 707 to form a support for the rubber sleeve 707. When the rubber sleeve 707 loses the pull of the adapter ring 804, the elastic support member 708 will use the ability of elastic deformation to push the rubber sleeve 707 to expand and reset, and at the same time, the elastic support member 708 can prevent the rubber sleeve 707 from completely shrinking and deflated.

[0052] In the above scheme, in order to remove the oxide scale generated during groove processing, the specific operations are as follows.

[0053] Reference Figure 1 to Figure 2 , Figures 4 to 5 , Fig.10 In a preferred embodiment, the processing mechanism 9 includes a telescopic rod 901 rotatably installed inside the flap 6, the telescopic rod 901 is distributed between the first rotating shaft 701 and the second rotating shaft 702 and is simultaneously transmission-sleeved inside the belt 703, a steel brush 902 is fixedly installed at the end of the telescopic rod 901, a bidirectional thread groove 904 is provided on the outer side of the telescopic rod 901, a fixed block 903 is installed in the middle of the flap 6, the telescopic rod 901 passes through the fixed block 903 and is threadedly connected to the fixed block 903 through the bidirectional thread groove 904.

[0054] In this embodiment: when the belt 703 rotates, it will also drive the telescopic rod 901 to rotate synchronously. The rotating telescopic rod 901 will be driven by the cooperation of the bidirectional thread groove 904 and the fixed block 903, so that it will reciprocate and contract. While contracting, it will drive the steel brush 902 to move back and forth, so that the oxide scale on the groove can be scraped and cleaned along with the operation of the mobile machine 5; wherein, a positioning rod 905 is horizontally fixed to the side of the fixed block 903, and the positioning rod 905 horizontally penetrates into the interior of the steel brush 902. The positioning rod 905 will cooperate with the rotation of the telescopic rod 901 to form a restriction on the steel brush 902, causing the steel brush 902 to reciprocate.

[0055] In the above solution, in order to ensure the stability of the second beveling wheel 706 during operation, the specific operation is as follows.

[0056] Reference Figure 2 , Figure 4 , Figure 6 and Fig. 9In a preferred embodiment, the snap-fit ​​assembly 805 includes a double ventilation pipe fitting 8051 fixedly mounted on the surface of the flap 6, a latch 8052 is slidably mounted inside the double ventilation pipe fitting 8051, a slot 8053 is provided on the top of an adapter ring 804, and the latch 8052 is distributed on the top of the slot 8053.

[0057] In this embodiment: Under normal circumstances, when the second beveling wheel 706 is sleeved on the outer side of the first beveling wheel 705, the pin 8052 located inside the double-vent pipe 8051 will be engaged with the inside of the slot 8053, thereby restricting the adapter ring 804, making it impossible for the second beveling wheel 706 that performs beveling processing on the plate to move; when the user wants to change the type of beveling processed by this equipment, the user needs to first control the three-way solenoid valve 801, so that the air path inside the double-vent pipe 8051 is connected first, and pull the pin 8052 by pumping air, so that the pin 8052 is moved out from the inside of the slot 8053, thereby releasing the restriction on the adapter ring 804, and then control the three-way solenoid valve 801 to open the air path inside the double-vent pipe 8051. The solenoid valve 801 is connected to the air path inside the three-way pipe 802, so that the air inside the three-way pipe 802 and the two telescopic sleeves 803 is pumped outward through the three-way solenoid valve 801, causing the telescopic sleeves 803 to shrink; and when the user needs to switch back to the first type of groove that can be processed by this equipment, the three-way solenoid valve 801 is reversely controlled to perform the above operation; wherein, the outer surfaces of the first rotating shaft 701 and the second rotating shaft 702 are both provided with positioning grooves 806, and the inner surfaces of the rubber sleeve 707 and the second beveling wheel 706 are respectively slidably connected to the two positioning grooves 806 to ensure that when the first rotating shaft 701 and the second rotating shaft 702 rotate, the rubber sleeve 707 and the second beveling wheel 706 can be driven to rotate synchronously.

[0058] Further, it is supplemented that a spring 8054 is fixedly connected between the latch 8052 and the double-vent pipe 8051. When the latch 8052 loses the push of air pressure, it will be pushed by the spring 8054 and reset.

[0059] Working principle: Before use, the user connects the gas collecting bottle 3 in series to an air pipe 4, and connects the gas path with the cutting machine 2 through the air pipe 4. At the same time, place the plate to be beveled on the side of the guide rail 1 and start the whole equipment. The cutting machine 2 will move slowly along the guide rail 1, and flame cut the edges and corners of the plate to cut a V-shaped bevel (such as Fig.13As shown in step 1 in the figure, further processing can be performed on the basis of the V-shaped groove. When the cutting machine 2 moves, the moving machine 5 is driven together. At this time, the motor 704 located on the top of the moving machine 5 is started synchronously, and the motor 704 drives the first rotating shaft 701 to rotate. The first rotating shaft 701 drives the second rotating shaft 702 to rotate through the belt 703. At this time, the first groove wheel 705 located at the end of the first rotating shaft 701 drives the second groove wheel 706 to rotate synchronously and further grinds on the basis of the V-shaped groove, thereby completing the groove of the plate, resulting in a "U"-shaped groove (such as Fig.13 At the same time, the rubber sleeve 707 at the end of the second rotating shaft 702 will rotate synchronously and move along with the movement of the mobile platform 5 to clean the inside of the groove (as shown in step 2). Fig.13 As shown in step 3), the belt 703 rotates and the telescopic rod 901 rotates synchronously. The rotating telescopic rod 901 is driven by the cooperation of the bidirectional thread groove 904 and the fixed block 903, so that it reciprocates and contracts. The steel brush 902 moves back and forth while contracting, so that the oxide scale on the groove is initially scraped and cleaned along with the operation of the mobile machine 5.

[0060] On the basis of the V-shaped groove, other shapes of grooves can be further processed. At this time, the user can control the three-way solenoid valve 801 to pump out the air inside the three-way pipe 802 and the two telescopic sleeves 803, so that the telescopic sleeve 803 shrinks. When the telescopic sleeve 803 shrinks, it will pull the second groove wheel 706 and the rubber sleeve 707 through the adapter ring 804, so that the first groove wheel 705 hidden inside the second groove wheel 706 is exposed, and the rubber sleeve 707 that is pulled will shrink and change its own shape and diameter, and the "VV" combination groove (such as Fig.13 As shown in step 6 in the figure, the "VV" combined groove is composed of two V-shaped grooves with different inclination angles, and the rubber sleeve 707 that deforms synchronously will fit the inner wall of the groove more closely and clean the groove by friction (as shown in step 6 in the figure). Fig.13 (as shown in step 7);

[0061] The present invention can process different shapes of grooves on the plate by selecting different types of first groove wheels 705 and second groove wheels 706 in combination with flame cutting. The processed shapes are not limited to the above-mentioned "VV-type combined groove", "V-type groove", "U-type groove", etc.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
