Description

Technical Field

[0001] The utility model relates to the field of stainless steel processing auxiliary components, in particular to a welding table for stainless steel processing. Background Art

[0002] Stainless steel products have high strength and hardness, as well as good plasticity and toughness. They are divided into two types according to the manufacturing method: hot rolling and cold rolling. Currently, products made of stainless steel plates are widely used in life, such as commonly used stainless steel pipes for transporting liquids. During their specific use, the connection between stainless steel pipes usually requires flanges.

[0003] Specifically, in the process of assembling the flange at the end of the stainless steel pipe, it is necessary to assemble the flange and the stainless steel pipe by welding so that the two form a coaxial combination. At present, the welding and assembly process is usually completed on a welding table. The operation method is usually to raise the stainless steel pipe through the welding table to the same horizontal line as the inner mouth of the flange. The operation is inconvenient, especially when the stainless steel pipe is long, or when the flange is connected to a curved stainless steel pipe, the assembly is inconvenient, resulting in low efficiency in welding and assembly of the flange and the stainless steel pipe. At the same time, after the stainless steel pipe is laid flat on the welding table, an assembler is required to hold the flange at the edge of the welding table and align it with the inner mouth of the stainless steel pipe and hold it, and then another person performs spot welding assembly. Since the operator holding the flange is in a squatting state and the flange is heavy and is prone to hand shaking, when the welding is completed later, the inner mouth of the stainless steel pipe and the inner mouth of the flange are prone to step phenomenon, resulting in rework, and even repeated rework is required to meet the welding and assembly requirements.

[0018] The above-mentioned welding table for stainless steel processing is used. Specifically, during the process of welding and assembling the flange workpiece and the stainless steel pipe, the stainless steel pipe is placed horizontally in the pipe placement groove on the top surface of the welding table body. The pipe end of the stainless steel pipe flange workpiece to be welded and assembled should be close to the workpiece supporting assembly. Then the flange workpiece is placed upright on the V-shaped storage block to keep it in a vertical upright state. At the same time, the handle is held to loosen the locking bolt and the guide sleeve is adjusted along the column to be coaxially aligned with the stainless steel pipe to be welded and assembled on the welding table body. After the inner openings of the two are coaxially aligned, the guide sleeve is kept stationary. Then, the inner end of the locking bolt is tightened to press it against the outer periphery of the column. The position height of the guide sleeve is locked, and then the position height of the flange workpiece is locked, which makes it convenient for the assembler to align the flange workpiece with the inner mouth of the stainless steel pipe and then perform welding assembly operations, replacing the assembly operation method of the operator holding the flange workpiece by hand, avoiding the situation where the flange workpiece is moved during the assembly process and causing the need for rework, and at the same time realizing the operation method of single-person assembly operation, without the need for additional personnel to cooperate in the operation, which is beneficial to improving the assembly efficiency of the operator as a whole. Since the clamping and fixing component is additionally provided at the position above the placement block, after the flange workpiece is placed upright on the placement block, the flange workpiece can be securely placed upright by the movable pressure block vertically descending and pressing on the outer top of the flange workpiece. The locking nut and the limiting nut are fixed on the placement block. Specifically, during operation, the locking nut and the limiting nut are first screwed separately to move away from the pressure seat. Then, the pressure seat will descend through the matching hole by vertically sliding along the screw rod and allow the movable pressure plate to contact the top periphery of the flange workpiece. Then, the locking nuts are screwed separately to press them on the top surface of the pressure seat. In this way, the pressure seat can drive the movable pressure block to press on the top periphery of the flange workpiece, and then complete the pressing of the flange workpiece from the top. In the process of pressing the flange workpiece, because the placement block and the movable pressure block are both covered with the lining plate fixed with the buffer material, the elastic buffering capacity of the lining plate can prevent the flange from being damaged in the process of vertically placing and pressing the flange workpiece. The surface of the flange workpiece is conducive to ensuring the integrity of the outer surface of the flange workpiece at the end of welding assembly. In this way, the flange workpiece is firmly fixed, and the flange workpiece is prevented from moving during the welding assembly process. In the subsequent process, the fixing of the flange workpiece can be released by loosening the locking nut to make the movable pressure block rise and leave the outer top of the flange workpiece. The fixing and releasing methods of the flange workpiece are simple and easy to operate, which is convenient for adjusting the welding assembly position of the flange workpiece in the circumferential direction during the welding process, and is convenient for timely loosening and evacuating the flange workpiece after the welding assembly is completed. In addition, since the outer periphery of the column is printed with the scale ruler for indicating the position height of the placement block when flange workpieces of different specifications are placed upright,Then, during the lifting and lowering adjustment of the placement block, the placement block can be quickly adjusted to a suitable position height for use by referring to the scale ruler, further facilitating the assembly work of the operator.

[0019] The beneficial effects are as follows: 1. The utility model places the stainless steel pipe on the top surface of the welding table body and places the flange workpiece upright on the V-shaped storage block to maintain a vertical upright state, and then adjusts the guide sleeve along the vertical lifting and locking of the column to make the flange workpiece coaxially aligned with the stainless steel pipe to be assembled, thereby facilitating the assembly personnel to weld and assemble the aligned flange workpiece with the stainless steel pipe, replacing the welding and assembly operation mode of the operator holding the flange workpiece by hand, avoiding the situation that the flange workpiece is moved turbulently during the welding and assembly process and causing the need for rework, and realizing the operation mode of single-person assembly operation, without the need for additional personnel to cooperate with the operation, which is conducive to improving the welding and assembly efficiency of the operator as a whole;

[0020] 2. A clamping and fixing component is added above the placement block. After the flange workpiece is placed upright on the placement block, the flange workpiece can be firmly placed upright on the placement block by vertically descending the movable pressure block and pressing it on the outer top of the flange workpiece. Since the flange workpiece is firmly fixed, the flange workpiece is prevented from moving around during the welding and assembly process. In the subsequent process, the flange workpiece can be released by only raising the movable pressure block to leave the outer top of the high flange workpiece. The fixing and releasing methods of the flange workpiece are simple and easy to operate, which is convenient for adjusting the welding and assembly position of the flange workpiece by circumferential rotation during the welding process, and is also convenient for timely loosening and evacuating the flange workpiece after the welding and assembly are completed.

[0021] 3. The outer periphery of the column is printed with a scale ruler to indicate the height of the placement block when placing flange workpieces of different specifications. Then, during the process of raising and lowering the placement block, the placement block can be quickly adjusted to the appropriate position height for use by referring to the scale ruler, which further facilitates the welding and assembly operations of the operator;

[0022] 4. The placement block and the movable pressure block are both covered with a lining plate fixed with a buffer material, and then the elastic buffering capacity of the lining plate can prevent the surface of the flange workpiece from being damaged during the process of vertically placing and pressing the flange workpiece, which is beneficial to ensure the integrity of the outer surface of the flange workpiece at the end of welding assembly.

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0038] See also Figure 1-Figure 11 As shown, the utility model provides a welding table for stainless steel processing, including a welding table body 5 and a bottom cabinet 6. The welding table body 5 is horizontally arranged, and the bottom surface of the welding table body 5 is fixed with the bottom cabinet 6 for padding support. The bottom of one side of the bottom cabinet 6 is horizontally extended and fixed with a mounting base 4 through a connecting plate 401, and the top surface of the mounting base 4 is vertically fixed with a column 1. The periphery of the column 1 is coaxially installed with a lifting and adjusting component 9 that can be vertically lifted and locked. Specifically, the lifting and adjusting component 9 includes a guide sleeve 903 and a locking bolt 902. The guide sleeve 903 is arranged on the periphery of the column 1 in a coaxial sliding fit manner, and the outer side of the guide sleeve 903 is radially provided with a mounting hole 90 4, and the mounting hole 904 is a through hole, and the mounting hole 904 is coaxially meshed with a locking bolt 902, and the inner end of the locking bolt 902 can be pressed against the periphery of the column 1 by twisting. Such a configuration is convenient for driving the placement block 303 to be raised and lowered by the guide sleeve 903 sliding vertically along the column 1. When the bottom end of the guide sleeve 903 is aligned with the scale mark on the scale ruler 8 corresponding to the flange workpiece specification, the guide sleeve 903 is kept stationary and the inner end of the locking bolt 902 is tightened and pressed against the periphery of the column 1, so as to lock the placement block 303 to the corresponding use position height, and then complete the position height adjustment of the placement block 303 and the placed flange workpiece.

[0039] See also Figure 1-Figure 2As shown, a workpiece supporting assembly 3 is horizontally extended on one side of the periphery of the lifting and adjusting assembly 9, so that the workpiece supporting assembly 3 can stably place the flange workpiece to be welded and assembled and adjust the welding assembly position height of the flange workpiece to be assembled through the lifting and adjusting assembly 9. Specifically, the workpiece supporting assembly 3 includes a wing seat 301 and a placement block 303. The wing seat 301 is horizontally extended and fixed on the front part of the periphery of the guide sleeve 903, and the extension direction of the wing seat 301 is parallel to the side direction close to the welding table body 5. A V-shaped placement block 303 is fixed on the top surface of the wing seat 301 at the front end position away from the guide sleeve 903, so that the flange workpiece to be assembled can be positioned and placed upright through the placement block 303, and the inner mouth axis of the flange workpiece is arranged horizontally after the flange workpiece is positioned and placed upright. The purpose of such arrangement is to smoothly place the flange workpiece upright on the upper position of the placement block 303 through the V-shaped design of the placement block 303 and naturally complete the positioning and placement operation.

[0040] See also Figure 3-Figure 6 As shown, a clamping and fixing component 2 for clamping and fixing the flange workpiece to be assembled from the top is extended and installed at the rear position of the workpiece supporting component 3. Specifically, the clamping and fixing component 2 includes an extension seat 206 and a pressure seat 204. The front position of the outer end surface of the wing seat 301 is horizontally extended and fixed with the extension seat 206, and the front and rear positions of the top surface of the extension seat 206 are vertically fixed with screws 202. The pressure seat 204 is suspended above the extension seat 206 in parallel. The bottom surface of the pressure seat 204 is located above the wing seat 301 and is provided with a movable pressure block 205 for clamping and fixing from the top of the outer periphery of the flange workpiece to be assembled. The movable pressure block 205 is compared with the placement block 303 from top to bottom and is symmetrical to each other. The pressure seat 204 is located above the extension seat 206 and the front and rear positions are vertically opened with matching holes 207. The matching holes 207 corresponds to the screw rod 202 respectively, and the screw rod 202 passes through the corresponding matching hole 207 in a vertical coaxial sliding fit. The part of the screw rod 202 extending out of the top of the matching hole 207 is coaxially engaged with the locking nut 203. The advantage of this arrangement is that after the flange workpiece is placed upright on the placement block 303, the flange workpiece can be firmly fixed upright on the placement block 303 by vertically descending the movable pressure block 205 and pressing it on the top of the outer periphery of the flange workpiece. Since the flange workpiece is firmly fixed, the flange workpiece is prevented from moving around during the welding and assembly process. In the subsequent process, the flange workpiece can be released by only raising the movable pressure block 205 to leave the top of the outer periphery of the flange workpiece. The fixing and releasing methods of the flange workpiece are simple and easy to operate.

[0041] See also Figure 1-Figure 2As shown, the lifting and adjusting component 9 is optimized as follows. Specifically, the outer end of the locking bolt 902 is installed with a handle 901 for facilitating personnel to apply force to rotate it. Such a configuration makes it convenient to tighten or loosen the locking bolt 902 by applying force by holding the handle 901. Preferably, the inner end of the locking bolt 902 can be coaxially installed with a cylindrical rubber block to ensure that when the inner end of the locking bolt 902 is pressed against the periphery of the column 1, the periphery of the column 1 is prevented from being crushed.

[0042] See also Figure 2-Figure 6 As shown, the clamping and fixing assembly 2 and the workpiece supporting assembly 3 are optimized as follows. Specifically, the portion of the screw rod 202 extending from the bottom of the matching hole 207 is coaxially engaged with the limit nut 208, so that when the pressure seat 204 and the movable pressure block 205 rise a certain distance, the position height of the pressure seat 204 and the movable pressure block 205 is limited by screwing the limit nut 208 to contact the bottom surface of the pressure seat 204, so that a single person can free up his hands to place the flange workpiece upright at the position of the storage block 303. At the same time, the locking nuts 203 are all butterfly nuts, and the top ends of the screw rods 202 at the front and rear positions are fixedly connected with a connecting end plate 201. Such a configuration facilitates the locking nuts 203 to be directly tightened or loosened by hand, and at the same time, it is convenient to strengthen the connection between the two screw rods 202 by setting a connecting end plate 201 between the top ends of the screw rods 202, improve the vertical stability, and prevent the locking nuts 203 from detaching from the top ends of the screw rods 202.

[0043] At the same time, a positioning back plate 302 is vertically fixed on the top surface of the wing seat 301 at a position outside the placement block 303 for the flange workpiece placed on the placement block 303 to lean against and support it. The purpose of this arrangement is to allow the flange workpiece to lean against the positioning back plate 302 to indicate that the flange workpiece is in place, and at the same time, to prevent the flange workpiece from accidentally tipping over during the welding and assembly process.

[0044] Moreover, the placement block 303 and the movable pressure block 205 are both angle steel sections, the placement block 303 and the movable pressure block 205 are mirror-symmetrical, and the positions on both sides of the placement block 303 and the movable pressure block 205 are symmetrically arranged and perpendicular to each other. Preferably, the placement block 303 and the movable pressure block 205 have the same specifications and are directly opposite to each other up and down. The purpose of such arrangement is that, firstly, the placement block 303 and the movable pressure block 205 are easy to process and manufacture, easy to obtain, and at the same time, the flange workpiece can naturally complete the positioning and placement operation when it is placed. At the same time, the placement block 303 and the movable pressure block 205 are both covered with a lining plate 10 fixed with a buffer material. Preferably, the lining plate 10 is a rubber plate, so that the elastic buffering capacity of the lining plate 10 can prevent the surface of the flange workpiece from being damaged during the process of vertically placing and pressing the flange workpiece, which is beneficial to ensure the integrity of the outer surface of the flange workpiece at the end of assembly.

[0045] See also Figure 1-Figure 3 As shown, the column 1 is optimized as follows. Specifically, the top of the column 1 is coaxially fixed with an anti-drop cap 101. Preferably, the anti-drop cap 101 is combined and connected with the column 1 by threaded matching, so that the guide sleeve 903 can be prevented from accidentally detaching from the top of the column 1 by the anti-drop cap 101. At the same time, the column 1 is located at the outer side of the top surface of the mounting base 4, and there is a certain distance between the inner side edges of the wing seat 301 and the pressure seat 204 and the adjacent outer side edges of the welding table body 5. The purpose of this arrangement is that after the flange workpiece is placed, during the welding and assembly process of the stainless steel pipe and the inner mouth of the flange workpiece, a gap is left between the wing seat 301 and the welding table body 5 to allow the welding sparks and welding slag generated by the welding tool to fall down smoothly. The front outer portion of the column 1 is printed with a scale ruler 8 for indicating the height of the position of the placement block 303 when flange workpieces of different specifications are placed upright. It is preferred that when marking the scale lines on the scale ruler 8, the reference position corresponding to the scale lines of the scale ruler 8 is the bottom end of the guide sleeve 903. At the same time, the scale lines of the scale ruler 8 should be obtained by placing a stainless steel pipe flat on the pipe groove 701 and aligning it with the flange workpiece for reference. The advantage of this arrangement is that when the position height of the placement block 303 is adjusted according to the specifications of the flange workpiece to be assembled, the placement block 303 can be quickly and accurately adjusted to the corresponding position height by referring to the bottom end of the guide sleeve 903 and the scale lines of the scale ruler 8.

[0046] See also Figure 1-Figure 2 As shown, the mounting base 4 and the welding table body 5 are optimized as follows, specifically, the connecting plate 401 is unfolded and welded on the inner end surface of the mounting base 4, and the connecting plate 401 is fixedly installed on the outer bottom corresponding to the bottom cabinet 6 by bolts installed around it. This arrangement facilitates the mounting base 4 to be smoothly assembled and fixed on the outer lower part of the bottom cabinet 6 through the connecting plate 401, and facilitates the smooth separation of the mounting base 4 from the bottom cabinet 6 in the later stage. A fixing block 7 is installed on the top surface of the welding table body 5 at a position close to the workpiece supporting assembly 3. The top surface of the fixing block 7 is provided with a pipe placing groove 701 for placing the stainless steel pipe in the horizontal direction. The cross-sectional shape of the pipe placing groove 701 along the longitudinal vertical surface is V-shaped, and the lowest position direction of the pipe placing groove 701 is located on the same vertical plane as the lowest position direction of the placement block 303. This arrangement facilitates the stainless steel pipe to be placed horizontally in the pipe placing groove 701 of the fixing block 7 to complete the limited placement of the stainless steel pipe during welding assembly, and facilitates the rapid positioning and comparison of the inner opening of the pipe end of the stainless steel pipe and the inner opening of the flange workpiece.

[0047] With the above structure, specifically in the process of welding and assembling the flange workpiece and the stainless steel pipe, the stainless steel pipe is placed horizontally in the pipe placing groove 701 on the top surface of the welding table body 5, and the pipe end position of the stainless steel pipe flange workpiece to be welded and assembled should be close to the workpiece supporting assembly 3, and then the flange workpiece is placed upright on the V-shaped placement block 303 to keep it in a vertical upright state. At the same time, the handle 901 is held and the locking bolt 902 is loosened, and then the flange workpiece is adjusted to be coaxially aligned with the stainless steel pipe to be welded and assembled on the welding table body 5 by means of the guide sleeve 903 which is adjusted and locked vertically along the column 1. After the inner openings of the two are coaxially aligned, the guide sleeve 903 is kept stationary, and then the position of the guide sleeve 903 is locked by tightening the inner end of the locking bolt 902 and pressing it against the outer periphery of the column 1. The height of the flange workpiece is set, and then the height of the position of the flange workpiece is locked, which makes it convenient for the assembler to align the flange workpiece with the inner mouth of the stainless steel pipe and then perform welding assembly operations, replacing the assembly operation method of the operator holding the flange workpiece by hand, avoiding the situation where the flange workpiece is moved during the assembly process and causing the need for rework, and at the same time realizing the operation method of single-person assembly operation, without the need for additional personnel to cooperate in the operation, which is beneficial to improving the assembly efficiency of the operator as a whole. Since a clamping and fixing component 2 is added at the position above the placement block 303, after the flange workpiece is placed upright on the placement block 303, the movable pressing block 205 is vertically lowered and pressed against the top of the outer periphery of the flange workpiece, so that the flange workpiece can be firmly placed upright and fixed on the placement block 303. 03, specifically during operation, first screw the locking nut 203 and the limiting nut 208 respectively to move them away from the pressure seat 204, then the pressure seat 204 will descend by vertically sliding along the screw rod 202 through the matching hole 207 and allow the movable pressure plate to contact the top periphery of the flange workpiece, and then screw the locking nuts 203 respectively to press them on the top surface of the pressure seat 204, so that the pressure seat 204 can drive the movable pressure block 205 to press on the outer top of the flange workpiece, and then complete the pressing of the flange workpiece from the top, and in the process of pressing the flange workpiece, because the placement block 303 and the movable pressure block 205 are both covered with a lining plate 10 fixed with a buffer material, the elastic buffering capacity of the lining plate 10 can prevent the flange workpiece from being damaged during the process of vertically placing and pressing the flange workpiece. The surface of the flange workpiece is conducive to ensuring the integrity of the outer surface of the flange workpiece at the end of welding assembly. In this way, the flange workpiece is firmly fixed, and the flange workpiece is prevented from moving during the welding assembly process. In the subsequent process, the fixing of the flange workpiece can be released by loosening the locking nut 203 and raising the movable pressure block 205 away from the outer top of the flange workpiece. The fixing and releasing methods of the flange workpiece are simple and easy to operate, which is convenient for adjusting the welding assembly position of the flange workpiece in the circumferential direction during the welding process, and is convenient for timely loosening and evacuating the flange workpiece after the welding assembly is completed. In addition, since the outer periphery of the column 1 is printed with a scale ruler 8 for indicating the height of the position of the placement block 303 when flange workpieces of different specifications are placed upright,Then, during the process of adjusting the lifting of the storage block 303, the storage block 303 can be quickly adjusted to a suitable position height for use by referring to the scale ruler 8, which further facilitates the assembly work of the operator.

[0048] At the same time, during the welding and assembly operation, the stainless steel pipe is placed horizontally in the pipe placement groove 701 of the fixed block 7 and the pipe end to be welded and assembled is placed close to the direction of the placement block 303. According to the specifications of the flange workpiece to be assembled, the placement block 303 is adjusted to the corresponding position height by referring to the bottom end of the guide sleeve 903 and the scale mark line of the scale ruler 8. During adjustment, the placement block 303 is driven to be raised and lowered by the guide sleeve 903 sliding vertically along the column 1. When the bottom end of the guide sleeve 903 is level with the scale mark line on the scale ruler 8 corresponding to the specifications of the flange workpiece, the guide sleeve 903 is kept stationary and the handle 901 is held to tighten the inner end of the locking bolt 902 and press it on The periphery of the column 11 is used to lock the placement block 303 to the corresponding height of the use position, and then the flange workpiece to be assembled is placed upright and pressed on the placement block 303. During operation, the distance between the placement block 303 and the movable pressure block 205 is first expanded to ensure that the flange workpiece can be smoothly placed on the placement block 303. Specifically, the locking nuts 203 are respectively tightened to be close to the connecting end plate 201, and then the pressure seat 204 and the movable pressure block 205 are vertically driven to rise to expand the distance between the placement block 303. Subsequently, the position of the pressure seat 204 and the movable pressure block 205 can be limited by screwing the limit nut 208 to rise to contact the bottom surface of the pressure seat 204 The height of the flange workpiece to be assembled is placed upright on the placement block 303 and against the positioning back plate 302. Since the placement block 303 is a V-shaped block, it ensures that the flange workpiece can be naturally positioned after being placed on the placement block 303. Then, the limiting nuts 208 at the two sides are screwed down to ensure that the pressure seat 204 and the movable pressure block 205 can smoothly fall until the movable pressure block 205 is pressed on the outer top of the flange workpiece. After the movable pressure block 205 is pressed on the outer top of the flange workpiece, the locking nuts 203 at the two sides are screwed down respectively until the locking nuts 203 are pressed on the top surface of the pressure seat 204, so as to lock the movable pressure block 205 to the flange workpiece The stainless steel pipe is in a pressed and fixed state, and then the stainless steel pipe is moved horizontally to align and maintain the coaxial structure of the stainless steel pipe and the pressed flange workpiece. The operator can step on the stainless steel pipe to prevent it from moving around, or the assistant can hold the stainless steel pipe to prevent it from moving around. Then the operator can perform the welding and assembly operation of the stainless steel pipe and the flange workpiece in the aligned position. When the welding and assembly is completed, the locking nut 203 is loosened to allow the pressure seat 204 and the movable pressure block 205 to rise and leave the top of the outer periphery of the flange workpiece. Then the assembly of the flange workpiece and the stainless steel pipe can be taken away and evacuated, thus completing a single assembly operation of the flange workpiece and the stainless steel pipe.
