Description

Technical Field

[0001] The invention relates to the field of welding equipment, and in particular to a processing equipment for a square tube and a processing method thereof. Background Art

[0002] Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made by rolling strip steel after processing.

[0003] After the square tube is extruded, the gaps on its edges need to be closed by welding to form a complete tubular structure. During this welding process, a small amount of liquid is sometimes sprayed near the welding area. The original intention of this practice is to use the cooling effect of the liquid to slightly moisten the surrounding area of ​​the welding area, so as to reduce the sparks generated during welding, thereby protecting the materials near the welding area from heat damage. However, it is worth noting that the amount of liquid sprayed must be controlled. If too much liquid is sprayed, especially water, when the water enters the welding area, it will instantly evaporate into steam due to the high temperature, and there will be at least the following problems:

[0004] 1. Impaired arc stability: The generation of steam will interfere with the stability of the welding arc, which may cause arc flickering or interruption, affecting the continuity of welding and the quality of the weld.

[0005] 2. Increased risk of hydrogen embrittlement: Hydrogen atoms in water decompose at high temperatures and may be absorbed by metals, leading to hydrogen embrittlement, which weakens the strength and toughness of the weld and increases the risk of weld cracks.

[0006] 3. Increased splashing: Although appropriate amount of moisture can reduce splashing, excessive water evaporation will increase splashing, which not only increases the difficulty of subsequent cleaning work, but may also cause safety risks such as burns to operators. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a processing device and a processing method for square tubes.

[0012] An anti-splash mechanism, which shields the sprayed liquid during the process of the liquid spraying mechanism spraying the liquid on the square tube to prevent excessive water from splashing onto the welding area;

[0013] Among them, during the spraying process, the liquid sprayed by the liquid spraying mechanism is shielded and absorbed by the anti-splash mechanism, so as to help prevent the liquid from being splashed to the welding area and affecting the welding; and as the square tube is transported by the conveying device, the anti-splash mechanism will also intercept and clean the impurities on the square tube, thereby helping to prevent impurities from entering the welding area and affecting the welding.

[0014] Preferably: the anti-splash mechanism comprises:

[0015] A card block, the card block is fixedly mounted on the connecting frame;

[0016] A card slot, the card slot is opened on the card block;

[0017] The water-absorbing sponge is slidably installed inside the slot, and the water-absorbing sponge abuts against the top of the square tube.

[0018] Preferably, it also includes:

[0019] A motor, wherein the motor is fixedly mounted on the connecting block;

[0020] A cleaning block, fixedly mounted on the output shaft end of the motor;

[0021] The rubber pad is arranged on the bottom of the cleaning block through a twisting mechanism.

[0022] Preferably: the torsion mechanism comprises:

[0023] A hole groove, the hole groove is opened at the bottom of the cleaning block;

[0024] A torsion rod, rotatably mounted inside the hole groove, the torsion rod being fixedly connected to the rubber pad;

[0025] The torsion spring is fixedly installed between the hole slot and the torsion rod, and the torsion spring is sleeved on the outer wall of the torsion rod.

[0026] Preferably, it also includes:

[0027] A gear, fixedly mounted on the outer wall of the output shaft end of the motor;

[0028] A rack, slidably connected to the side wall of the block;

[0029] A slide frame is fixedly connected between the absorbent cotton and the rack.

[0030] Preferably: also include:

[0031] A plurality of cleaning strips are fixedly connected to the cleaning block, and the cleaning strips are made of soft material.

[0032] Preferably: also include:

[0033] A shielding cover is fixedly mounted on a side of the block away from the rack, and the shielding cover is used to shield one side of the absorbent cotton.

[0034] In a second aspect, the present invention provides a processing method for a processing device for a square tube, the processing method comprising the following steps:

[0035] Acquire first parameter information, wherein the first parameter information includes moisture and humidity information of a current welding area;

[0036] Set a threshold in advance;

[0037] Compare the obtained humidity information with the threshold value;

[0038] If the result is greater than the threshold, the water spraying amount of the liquid spraying mechanism is reduced and / or the water spraying angle is changed;

[0039] If the result is less than the threshold value, the water spraying amount of the liquid spraying mechanism is increased and / or the water spraying angle is changed.

[0040] It should be noted that the threshold value is a preset value, which means that the humidity information is within the optimal welding humidity.

[0041] Preferably: also includes a timing unit:

[0042] Get the timing completion information of the timing unit;

[0043] generating first control information according to the timing completion information;

[0044] The first control information is sent to the motor to start the motor, so as to drive the cleaning block to rotate.

[0045] Preferably: the timing unit is specifically a timer.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. The present invention provides an anti-splash mechanism to shield and absorb the liquid sprayed by the liquid spraying mechanism, so as to help prevent the liquid from splashing to the welding area and affecting the welding; and as the square tube is transported by the conveying device, the anti-splash mechanism will also intercept and clean the impurities on the square tube, so as to help prevent the impurities from entering the welding area and affecting the welding.

[0048] 2. The present invention provides a rubber pad and a torsion spring. If, during the rotation of the cleaning block, the friction between the rubber block and the square tube is insufficient to restrict the rubber block from rotating with the cleaning block after the impurities are removed, the torsion spring will quickly push the rubber block to follow the rotation angle of the cleaning block. In this process, on the one hand, it is beneficial to utilize the spring force released by the torsion spring to push the rubber block to remove stubborn impurities on the travel path. On the other hand, after the rubber block is pushed by the spring force released by the torsion spring, it can also effectively push the removed impurities to the part outside the surface of the square tube, thereby helping to prevent the impurities from re-adhering to the surface of the tube and facilitating subsequent welding.

[0049] 3. The present invention provides a slide. As the rubber block rotates, the rubber block will first push and wipe off the moisture on the path of travel. Then, the rubber block cooperates with the moisture to help better remove impurities on the surface of the square tube. Secondly, during the tilting process of the rubber block, the moisture sprayed by the slide squeezing the absorbent cotton will flush the tilted rubber block. On the one hand, it helps to flush away impurities adhering to the rubber block, which is helpful for subsequent normal use. On the other hand, it squeezes out the moisture inside the absorbent cotton, which helps to continue absorbing water and prevents the absorbent cotton from being saturated with water, resulting in a poor moisture interception effect, thereby affecting the welding effect.

DETAILED DESCRIPTION

[0060] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0061] like Figures 2 to 9 The processing equipment for square tubes shown in the figure comprises a base frame 1, a roll forming device 101 and a welding frame 2, a conveying device 102 is arranged on the base frame 1, the roll forming device 101 and the welding frame 2 are respectively located on both sides of the conveying device 102, a welding device 104 is arranged on the welding frame 2, and further comprises:

[0062] Liquid spraying mechanism 105, the liquid spraying mechanism 105 is used to spray liquid on the surface of the square tube before it enters the welding position;

[0063] The connecting block 3 is fixedly mounted on the welding frame 2;

[0064] The connecting frame 4 is fixedly mounted on the side wall of the connecting block 3;

[0065] The anti-splash mechanism shields the sprayed liquid during the process of the liquid spraying mechanism 105 spraying the liquid on the square tube to prevent excessive water from splashing onto the welding area;

[0066] It should be understood that the square tube is placed in a suitable position, and after the placement is completed, the square tube is roll-formed by the roll-forming device 101 to obtain the desired shape. In this process, the conveying device 102 will convey the square tube after forming to the direction of the welding device 104. Before the square tube is welded, the liquid is continuously sprayed on the square tube by the liquid spraying mechanism 105, which helps to utilize the cooling effect of the liquid and slightly wet the surrounding area of ​​the welding area, so as to reduce the spark splashing generated during welding, thereby protecting the materials near the welding area from thermal damage. In the process of spraying, the liquid sprayed by the liquid spraying mechanism 105 is shielded and absorbed by the anti-splashing mechanism, so as to help prevent the accumulation of too much water in the welding area and affect the subsequent welding;

[0067] Furthermore, as the square tube is transported by the transport device 102, the anti-splash mechanism will intercept and clean the impurities on the square tube, thereby helping to prevent the impurities from entering the welding area and affecting the welding.

[0068] It should be noted that the roll-forming device 101 includes existing technical components such as conveying rollers and a drive motor 8, which will not be elaborated on in detail; the transportation device includes existing components such as power parts and conveying rollers, which are existing mature technologies and will not be disclosed in detail; the welding device 104 includes existing components such as a welding head, which will not be disclosed in detail. The above are all relatively mature existing technologies and are used in various industries and will not be disclosed in detail.

[0069] It needs to be explained again that the liquid spraying mechanism 105 includes a combination of existing components such as a spraying pipe, a liquid storage tank and a spraying head, which will not be elaborated in detail.

[0070] As a technical optimization solution of the present invention: the anti-splash mechanism includes:

[0071] A card block 5, which is fixedly mounted on the connecting frame 4;

[0072] A card slot 6, which is provided on the card block 5;

[0073] The water-absorbing sponge 7 is slidably installed inside the card slot 6, and the water-absorbing sponge 7 is in conflict with the top of the square tube;

[0074] It should be understood that the square tube is located inside the card slot 6, and the absorbent cotton is in contact with the square tube. In the process of spraying liquid, the card block 5 will block the liquid to help prevent the liquid from passing through. Through the efficient water absorption performance of the absorbent cotton, the square tube can remain relatively dry before reaching the welding area, and the reduction of surface moisture of the square tube can not only ensure the smooth progress of the welding process, but also improve the quality and strength of the weld. At the same time, when the absorbent cotton becomes wet after absorbing water, it can more effectively remove tiny impurities and dirt attached to the surface of the square tube. This is because the friction between the wet absorbent cotton and the impurities is greater, and these impurities can be wiped off more thoroughly, thereby ensuring the cleanliness of the surface of the square tube, creating favorable conditions for subsequent welding or other surface treatment processes.

[0075] As a technical optimization solution of the present invention: it also includes:

[0076] Motor 8, motor 8 is fixedly mounted on the connecting block 3;

[0077] A cleaning block 9 is fixedly mounted on the output shaft end of the motor 8;

[0078] A rubber pad 10 is arranged at the bottom of the cleaning block 9 through a twisting mechanism;

[0079] It should be understood that after the absorbent cotton cleans the square tube for the first time, the square tube will continue to be transported because the rubber pad 10 will contact the surface of the square tube and the friction will further remove the residual impurities. The design of the rubber pad 10 can effectively scrape off those stubborn dirt and residual substances that are not easy to be completely removed by the absorbent cotton.

[0080] As a technical optimization solution of the present invention: the torsion mechanism includes:

[0081] A hole groove 11, which is formed at the bottom of the cleaning block 9;

[0082] The torsion rod 12 is rotatably mounted inside the hole groove 11, and the torsion rod 12 is fixedly connected to the rubber pad 10;

[0083] The torsion spring 13 is fixedly installed between the hole slot 11 and the torsion rod 12, and the torsion spring 13 is sleeved on the outer wall of the torsion rod 12;

[0084] It should be understood that after a certain period of time of cleaning the square tube by the rubber pad 10, certain impurities will accumulate on the rubber pad 10, which may affect the cleaning effect. Therefore, after a certain period of time, the motor 8 is controlled to drive the cleaning block 9 to rotate. Because the bottom of the rubber pad 10 contacts the top of the square tube, a friction force will limit the rotation of the rubber pad 10 itself, so the cleaning block 9 will rotate with the torsion rod 12 as the axis, and the torsion spring 13 will accumulate force during the torsion process. When the cleaning block 9 and the torsion rod 12 cannot be in relative position, the cleaning block 9 will drive the rubber block to rotate through the torsion rod 12 to tilt the rubber block. During the tilting process of the rubber block, as the square tube moves, the rubber block will still clean the impurities on the square tube.

[0085] Secondly, if during the rotation of the cleaning block 9, the friction between the rubber block and the square tube may be insufficient to restrict the rubber block from rotating with the cleaning block 9 after the impurities are removed, the torsion spring 13 will quickly push the rubber block to follow the rotation angle of the cleaning block 9. In this process, on the one hand, it is beneficial to use the spring force released by the torsion spring 13 to push the rubber block to remove stubborn impurities on the travel path. On the other hand, after the rubber block is pushed by the spring force released by the torsion spring 13, it can also effectively push the removed impurities to the part outside the surface of the square tube, thereby helping to prevent the impurities from re-adhering to the surface of the pipe, so as to facilitate subsequent welding.

[0086] As a technical optimization solution of the present invention: it also includes:

[0087] The gear 15 is fixedly mounted on the outer wall of the output shaft end of the motor 8;

[0088] The rack 16 is slidably connected to the side wall of the block 5;

[0089] The slide 17 is fixedly connected between the water-absorbing sponge 7 and the rack 16;

[0090] It should be understood that during the rotation of the motor 8, the gear 15 will be driven to rotate, and the gear 15 will drive the rack 16 to slide on the side wall of the block 5. The rack 16 drives the absorbent cotton to be compressed to one side through the slide 17. In this process, under normal circumstances, the cleaning block 9 will rotate first, and finally the rubber block will rotate. In the time difference between the two, the slide 17 will push the absorbent cotton to be compressed to one side. Because part of the water will be squeezed out from the inside of the absorbent cotton during the compression process, the reserved time difference will help the rubber block to block the water that overflows first, and prevent the water from following the square tube to move to the inside of the welding area, and as the volume of the sponge is compressed The water in the absorbent cotton will be squeezed out after it is compressed, and as the rubber block rotates, the rubber block will first push and wipe off the water on the way, and then the rubber block cooperates with the water to help better remove impurities on the surface of the square tube. Secondly, when the rubber block is tilted, the water sprayed by the slide 17 squeezing the absorbent cotton will flush the tilted rubber block. On the one hand, it helps to flush away impurities adhering to the rubber block, which is helpful for subsequent normal use. On the other hand, squeezing out the water inside the absorbent cotton helps to continue absorbing water, preventing the absorbent cotton from being saturated with water, resulting in a poor water interception effect, thereby affecting the welding effect.

[0091] As a technical optimization solution of the present invention: it also includes:

[0092] A plurality of cleaning strips 18 are fixedly connected to the cleaning block 9, and the cleaning strips 18 are made of soft material;

[0093] It should be understood that during the initial rotation of the cleaning block 9, the cleaning block 9 will drive the cleaning strip 18 to clean the impurities, which helps to further reduce the impurities, and during the return process, the cleaning strip 18 will clean the impurities again in the same way as above.

[0094] It should be noted that the cleaning strip 18 may be made of a water-absorbent material, which helps to absorb moisture and further reduce the situation where moisture moves to the welding area along the square tube.

[0095] As a technical optimization solution of the present invention: it also includes:

[0096] The shielding cover 19 is fixedly mounted on the side of the block 5 away from the rack 16, and the shielding cover 19 is used to shield one side of the absorbent cotton;

[0097] It should be understood that by providing the shielding cover 19, the flow of water to the other side during the squeezing process is reduced, thereby helping the absorbent cotton to spray the water inside it to one side of the rubber pad 10, so as to help achieve a better flushing effect.

[0098] like Figure 1A processing method for a square tube processing device is shown, and the processing method comprises the following steps:

[0099] Acquire first parameter information, where the first parameter information includes moisture information of the current welding area;

[0100] Set a threshold in advance;

[0101] Compare the obtained humidity information with the threshold value;

[0102] If the result is greater than the threshold, the water spraying amount of the liquid spraying mechanism 105 is reduced and / or the water spraying angle is changed;

[0103] If the result is less than the threshold, the water spraying amount of the liquid spraying mechanism 105 is increased and / or the water spraying angle is changed.

[0104] As a technical optimization solution of the present invention: it also includes a timing unit:

[0105] Get the timing completion information of the timing unit;

[0106] generating first control information according to the timing completion information;

[0107] The first control information is sent to the motor 8 to start the motor 8 , so as to drive the cleaning block 9 to rotate.

[0108] As a technical optimization solution of the present invention: the timing unit is specifically a timer 14.

[0109] It should be noted that the timer 14 is fixedly mounted on the side wall of the base frame 1 .

[0110] Working principle of the present invention:

[0111] When the present invention is used, the square tube is placed in a suitable position. After the placement is completed, the square tube is roll-formed by the roll-forming device 101 to obtain the expected shape. In this process, the conveying device 102 will convey the square tube after the forming to the direction of the welding device 104. Before the square tube is welded, the liquid is continuously sprayed on the square tube by the liquid spraying mechanism 105, which helps to utilize the cooling effect of the liquid to slightly wet the surrounding of the welding area, thereby reducing the spark splashing generated during welding, thereby protecting the materials near the welding area from thermal damage. During the spraying process, the liquid sprayed by the liquid spraying mechanism 105 is shielded and absorbed by the anti-splashing mechanism, so as to help prevent the liquid from being splashed to the welding area and affecting the welding;

[0112] Furthermore, as the square tube is transported by the transport device 102, the anti-splash mechanism will intercept and clean the impurities on the square tube, thereby helping to prevent the impurities from entering the welding area and affecting the welding.

[0113] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
