Description

Technical Field

[0001] The invention relates to the technical field of fixing and positioning workpieces during welding, and in particular to a T-profile manufacturing device and a manufacturing method. Background Art

[0002] In the process of shipbuilding, longitudinal bones are needed. Generally, flat steel, bulb flat steel, angle steel and T-shaped steel can be used. T-shaped steel can provide stronger longitudinal and transverse support than other profiles due to its unique T-shaped cross-section design. This structural characteristic enables T-shaped steel to significantly increase the overall structural stability of the hull in shipbuilding, ensuring that the ship has good stability and wind and wave resistance during navigation at sea, so it is more widely used in shipbuilding.

[0003] The T-profile includes a face plate and a vertical face plate set on the web. The edge of the web is welded and set in the middle of the face plate to form a T-shaped cross-section. In the manufacturing process of the T-profile, two flat plates are usually processed and then welded together. Since the face plate and the web are independent of each other and have a large weight, when welding, it is necessary to first put the face plate and the web in place, and use auxiliary devices to maintain the two in a perpendicular state, and then weld them together. For example, a Chinese utility model patent with an authorization announcement date of April 21, 2020 and an authorization announcement number of CN210359994U discloses a T-profile anti-dumping device (i.e., a T-profile manufacturing device), which includes a bottom profile (i.e., a base), two positioning plates are arranged at intervals on the bottom profile, outer sleeves are fixed on the positioning plates, an inner sleeve and an L-shaped plate (i.e., a web clamp) fixed on the inner sleeve are nested in the outer sleeve, the two L-shaped plates are arranged oppositely, a clamping space for clamping the web of the T-profile is formed between the two L-shaped plates, and a placement space for preventing the T-profile panel is formed between the two outer sleeves. The device can complete the relative limitation of the panel and web in the T-profile, making it convenient to weld the panel and web together.

[0004] However, in the above technical solution, before placing the panel, the L-shaped plate and the inner sleeve need to be taken out from the outer sleeve, and then the L-shaped plate and the inner sleeve need to be placed in the outer sleeve after the panel is placed. The operator needs to manually operate during the process of taking out and installing the L-shaped plate, which is cumbersome and inefficient. Summary of the invention

[0005] In view of this, the present invention provides a T-profile manufacturing device to solve the problem in the prior art that the web clamping parts need to be disassembled and installed in sequence when welding T-profiles, resulting in cumbersome operations and low efficiency; the present invention also provides a T-profile manufacturing method to solve the above-mentioned technical problems.

[0006] The left and right clamping members are respectively hingedly connected to the base to form a lever structure. The panel seat is vertically guided on the base. The left and right clamping members both include an active arm located below the panel seat to a hinged position with the base and capable of relative movement with the panel seat, and a clamping arm for clamping the web. The clamping arm is provided with an abutting structure for abutting against the web after the web is placed. The left and right clamping members respectively have a clamping state in which the active arm is driven by the descending panel seat to clamp the web and a releasing state in which the clamping arm recovers after the T-profile is taken out and drives the panel seat to rise.

[0007] Furthermore, an elastic member is provided between the base and the web clamping member to keep the web clamping member in a released state.

[0008] Furthermore, the elastic member is a tension spring arranged between the base and the clamping arm.

[0009] Further, the abutment structure comprises an abutment rod, and an end of the abutment rod is used for abutment contact with the web.

[0010] Furthermore, at least two abutment rods are provided on the left clamping member and the right clamping member, and the ends of the abutment rods on each clamping member are flush.

[0011] Furthermore, a stepped groove is provided on the panel seat, and the width of the stepped groove decreases from top to bottom to limit the panels of different specifications.

[0012] Furthermore, a roller for contacting the bottom surface of the panel seat is provided at the end of the active arm.

[0013] Further, the clamping arm is L-shaped, and comprises a connecting rod connected to the hinged position and an abutment rod arranged perpendicular to the connecting rod, and the abutment rod constitutes the abutment structure.

[0014] The beneficial effects of the T-profile manufacturing device in the present invention are as follows: the T-profile manufacturing device in the present invention facilitates the limiting of the panel and the web by setting a base, a panel seat and a web clamp, facilitates the placement of the panel and the web in place and facilitates the welding operation of the cut-off portion; by setting the left clamp and the right clamp of the web clamp as a lever structure hinged on the base, it is convenient to move the web clamp, and thus facilitates the clamping or releasing of the web; by dividing the web clamp into an active arm and a clamping arm along the hinged position, and the end of the active arm is set below the panel seat and can be adjusted through the panel seat, it is convenient to drive the movement of the active arm through the movement of the panel seat, and then drive the movement of the clamping arm; by setting an abutment structure on the clamping arm, it is convenient to Under the combined action, the web is clamped in the middle position; since the clamping piece has a clamping state and a releasing state, after the panel and the web are placed on the panel seat, the weight of the panel and the web can drive the panel seat to descend, and drive the active arm and then drive the clamping arm to complete the clamping, that is, reach the clamping state, and after the T-profile is taken out, since there is no longer a large gravity on the panel seat, the clamping arm recovers and the clamping arm automatically opens at this time; that is, after the panel and the web are placed on the panel seat, the clamping arm will automatically clamp, and when the T-profile is taken out under the action of the sling, the clamping arm will automatically open, and will not affect the removal of the T-profile, thereby solving the problem of cumbersome and inefficient operation caused by the need to disassemble and install the web clamps in sequence when welding the T-profile in the prior art.

[0015] A T-profile manufacturing method uses the above-mentioned T-profile manufacturing device, first placing the panel on the panel seat, then placing the web above the panel and allowing the web clamping piece to complete the clamping of the web under the action of gravity, and then welding the corner seams on both sides between the web and the panel at the same time.

[0016] Furthermore, when welding the corner seams on both sides, the welding positions of the welding machines are maintained at a spacing of not less than 500 mm and continuously advanced in the same direction.

[0017] The beneficial effect of the T-profile manufacturing method in the present invention is that the T-profile manufacturing method in the present invention uses the above-mentioned T-profile manufacturing device, places the panel in the panel seat, and places the web above the panel. Naturally, under the action of the gravity of the panel and the web, the panel seat can move downward relative to the base, thereby driving the active arm in the lever structure to move, so that the clamping arm can be clamped on the web, so that the positioning of the panel and the web is automatically completed. Since the web is now in a vertical state with both sides suspended in the air, it is also convenient to simultaneously weld the corner seams on both sides of the web and the intersection with the panel, thereby solving the problem of cumbersome operation and low efficiency caused by the need to disassemble and install the web clamps in sequence when welding T-profiles in the prior art.

[0030] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0031] In the embodiment of the T-profile manufacturing device in this embodiment:

[0032] like Figure 1As shown, in this embodiment, the T-profile manufacturing device includes a base 2, on which a panel seat 1 for placing a panel 71 is provided, and the panel seat 1 is arranged on the base 2 along the vertical direction. Specifically, a guide hole is provided on the base 2, and a guide column 13 adapted to the guide hole is provided at the bottom of the panel seat 1. The guide column 13 is arranged vertically, so that the panel seat 1 can make a linear motion relative to the base 2 along the vertical direction. In order to prevent the panel seat 1 from rotating relative to the base 2, the guide column 13 is a polygonal column, and the guide hole is located in the polygonal hole adapted to the guide column 13. In this embodiment, the guide column 13 is a square column (i.e., a quadrilateral column), and the guide hole is a square hole. Of course, in other embodiments, the guide column can also be a guide column with a cross-section of a pentagon or triangle or other forms.

[0033] The T-profile manufacturing device also includes a web clamping member, which is provided with two groups, and the two groups of web clamping members are horizontally spaced. The web clamping members in each group include a left clamping member 3 and a right clamping member 4 for clamping on both sides of the web 72. The left clamping member 3 and the right clamping member 4 have the same structure and are symmetrically arranged on the base 2 about the web 72 to be clamped. The left clamping member 3 and the right clamping member 4 are respectively hingedly connected to the base 2 to form a lever structure, and the lever structure is divided into two parts along its hinge position, one part of which is used to contact the panel seat 1 relative to the other part for clamping the web 72. The part of the web clamping member used for connecting between the hinge position and the panel seat 1 constitutes the active arm 51, and the other part constitutes the clamping arm 52. The active arm 51 and the bottom of the panel seat 1 are movably matched, that is, the active arm 51 can support the panel seat 1, and the panel seat 1 also has a squeezing effect on the active arm 51. That is, the panel seat 1 can drive the active arm 51 to move downward, and the active arm 51 can support the panel seat 1 to move upward.

[0034] Specifically, the active arm 51 is a rod-shaped structure, one end of which extends to the hinge position, and the other end is located at the bottom of the panel seat 1. A roller 511 is also provided at one end of the active arm 51 located at the bottom of the panel seat 1. The roller 511 is used to roll in contact with the bottom of the panel seat 1. Since the active arm 51 has a certain hinge axis, when the panel seat 1 moves up and down, the end of the active arm 51 located below the panel seat 1 will swing in a circle. During the swinging process, there will be not only a sub-movement in the vertical direction, but also a sub-movement in the horizontal direction, that is, the end of the active arm 51 and the panel seat 1 will move relative to each other. The setting of the roller 511 makes the movement between the active arm 51 and the panel seat 1 a rolling movement, thereby reducing the friction between the two during the relative movement. Of course, in other embodiments, the active arm can also be set as a bare rod, in which case the roller is no longer set at the end, and the active arm and the panel seat are in a sliding fit.

[0035] The clamping arm 52 is L-shaped, and the clamping arm 52 includes a connecting rod 521 connected to a hinged position and an abutting rod 522 arranged perpendicularly to the connecting rod 521, and the abutting rod 522 constitutes an abutting structure on the web clamping member. The L-shaped shape is convenient for exposing the contact position between the web 72 and the panel 71 after the web 72 is clamped, so as to facilitate the corner welding between the panel 71 and the web 72. Specifically, at least two abutting rods 522 are provided on each left clamping member 3 and the right clamping member 4, and the end of each abutting rod 522 is used to abut against the web 72. The end of the abutting rod 522 on each clamping member is flush, so that the end of the abutting rod 522 on the same clamping member is in the same plane, which is convenient for clamping the side of the web 72. When the clamping members on both sides complete the abutment contact at the same time, there are a total of four abutment contact points on both sides of the web 72, which prevents the web 72 from tilting, thereby facilitating the maintenance of the relative position of the panel 71 and the web 72 during welding.

[0036] Of course, in other embodiments, the clamping arm may no longer be L-shaped, but may be C-shaped or other shapes. Alternatively, in other embodiments, the number of abutment rods may be adaptively adjusted, such as setting three or four abutment rods on each clamping member, or of course, setting one abutment rod. Alternatively, in other embodiments, the abutment structure is no longer an abutment rod, but an abutment block.

[0037] During use, the clamping arms 52 in the left clamping member 3 and the right clamping member 4 can move toward each other to clamp the web 72, that is, the clamping state, or can move relative to each other to conveniently release the web 72 and allow the panel 71 to pass, that is, the releasing state. In order to prevent the web clamping member from obstructing the panel 71 during placement, it is also necessary to make the left clamping member 3 and the right clamping member 4 both in the releasing state without external force. After the panel 71 and the web 72 are placed, the weight of the panel 71 and the web 72 will be transferred to the panel seat 1. The panel seat 1 moves downward under the action of gravity, thereby driving the active arm 51 to move, so that the clamping arms 52 are close to each other to complete the clamping of the web 72. Then, it is also necessary to have an automatic recovery structure that allows the left clamping member 3 and the right clamping member 4 to return from the clamping state to the releasing state when the panel seat 1 is not subject to gravity. In this embodiment, an elastic member that allows the web clamping member to be in the releasing state is also provided between the base 2 and the web clamping member. Specifically, the elastic member is a tension spring arranged between the base 2 and the clamping arm 52, and an upwardly protruding ear plate is arranged on the base 2, and a mounting rod is arranged on the ear plate, and one end of the tension spring is fixedly arranged on the mounting rod. When the web clamp is in the released state, the connection point between the tension spring and the clamping arm 52 is directly above the ear plate, and the tension spring is the shortest at this time. When the web clamp is in the clamping state, the tension spring is stretched, and the tension spring can provide a larger elastic force to overcome the web clamp, so that the web clamp is always in the released state without being subjected to additional external force. Of course, in other embodiments, the elastic member can also be a compression spring arranged between the active arm 51 and the base 2. Or, in other embodiments, the shape of the web clamp can also be changed so that the center of gravity of the web clamp in the released state is located outside the hinged position, and the web clamp is automatically restored to the released state by the gravity of the web clamp itself.

[0038] During welding, the web 72 needs to be located directly above the panel 71 and in the middle position. The position of the web 72 in the horizontal direction has been limited, so the position of the panel 71 on the panel seat 1 needs to be adjusted. Both ends of the panel seat 1 in the width direction are provided with flanges extending upward to limit the limit position of the panel 71 in width, and the space between the flanges constitutes a limiting groove 12 for limiting the panel 71. Before welding, the position of the panel 71 needs to be adjusted first so that the web 72 is located in the middle position of the panel 71. Of course, in other embodiments, in order to achieve the correspondence between the web 72 and the panel 71, the position of the panel 71 can also be limited by the panel seat 1, such as providing a stepped groove in the middle position of the panel seat 1, the width of the stepped groove is reduced from top to bottom to limit the panels 71 of different specifications, and each layer of the stepped groove constitutes a limiting groove 12 for limiting the panel 71, and the limiting groove 12 makes the panel 71 in the middle position, so that the panel 71 and the web 72 can be in a suitable position for welding after being placed.

[0039] During welding, at least two of the above-mentioned T-profile manufacturing devices are used, and multiple T-profile manufacturing devices are arranged in the same direction at intervals, and the limiting grooves 12 are oriented in the same direction, and then the panel 71 and the web 72 required for welding the T-profile 7 need to be placed in. First, the panel 71 is horizontally placed in the panel seat 1 using a magnetic hanger, and then the web 72 is lifted between the left clamp 3 and the right clamp 4 using a G-shaped hanger. Under the gravity of the panel 71 and the web 72, the panel seat 1 descends and drives the left clamp 3 and the right clamp 4 to complete the clamping of the web 72, and adjusts the position of the panel 71 so that the web 72 is exactly in the center of the panel 71, and then welding is required. When welding, it is necessary to weld the corner seams on both sides of the web 72 and at the intersection with the panel 71. During the welding process, due to the welding heat and the shrinkage of the formed molten pool, the web 72 or the panel 71 after welding will be deformed, affecting the forming quality of the T-profile 7. Therefore, in this embodiment, the corner seams on both sides of the web 72 are welded at the same time. Specifically, when welding the corner seams on both sides, use a welding clamp or adsorb it on the web 72, and then drag the welding gun to keep advancing. During the advancement process, the positions of the welding guns on both sides are kept at a distance of not less than 500 mm and advance in the same direction to prevent the high temperature on both sides from welding through the web 72. Of course, in other embodiments, if the thickness of the web 72 is large, the distance between the positions of the two welding guns can also be shortened.

[0040] In an embodiment of the T-profile manufacturing method of the present invention:

[0041] The T-profile manufacturing method in this embodiment uses the above-mentioned T-profile manufacturing device, and its manufacturing method is the same as the method of use in the above-mentioned T-profile manufacturing device, which will not be repeated here.

[0042] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
