A furniture hardware corner welding and forming fixing tooling

Abstract

The present invention belongs to the technical field of welding tooling, and specifically relates to a furniture hardware corner welding and forming fixing tooling, which includes a load-bearing component. A stainless steel frame body is arranged inside the load-bearing component, a side welding component is arranged on the top of the load-bearing component, and a pressurizing component is arranged on the upper part of the side welding component. When manual correction is used for welding repair work, since the stainless steel has a relatively high hardness, by manually squeezing and bending the baffle plates, it is often impossible to make the horizontal panel form a right angle with all the bent baffle plates. At this time, when welding repair work is carried out, the finished product tabletop may not be able to be buckled on the preset plane. When welding work is carried out through this device, plastic shaping blocks can be filled at the four corners inside the stainless steel frame body, and the bent baffle plates around can be pressurized with the plastic shaping blocks as a guide, ensuring that all the bent baffle plates can be welded to the horizontal panel in a vertical state, thereby avoiding welding defects and ensuring that the stainless steel frame body is more easily formed.

Description

Technical Field

[0001] The present invention belongs to the technical field of welding tooling, and specifically relates to a fixed tooling for welding and forming furniture hardware corners. Background Art

[0002] Furniture hardware refers to the hardware components of furniture or metal fittings used on furniture, mainly including slide rails, hinges, sofa feet, lifters, backrest frames, springs, nail guns, foot codes, pull-out baskets, etc. Hardware parts have functions such as connection, movement, fastening, and decoration, and are also called furniture fittings.

[0003] For large stainless steel tabletop welding corners, it is necessary to ensure that their corners are perpendicular to each other at 90° to carry out the normal use work of the furniture tabletop. Otherwise, defects or side deviations and other bad phenomena will occur at the corners of the tabletop. Therefore, workers need to carry out welding repair work on its corners during factory production. When manually correcting and carrying out welding repair work, due to the relatively high hardness of stainless steel, it is often impossible to form a vertical angle for welding repair work, resulting in the finished tabletop sometimes unable to be buckled on the preset plane. Therefore, a special device for welding repair of stainless steel tabletops is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a fixed tooling for welding and forming furniture hardware corners, including a load-bearing component. A stainless steel frame is arranged inside the load-bearing component. A side welding component is arranged on the top of the load-bearing component, and a pressurizing component is arranged on the upper part of the side welding component.

[0005] The load-bearing component includes a hollow bottom plate. Support connecting rods are symmetrically arranged on the upper surface of the hollow bottom plate. An adsorption magnetic plate is fixedly connected to the inner cavity of the hollow bottom plate. A control axis cylinder is fixedly connected to the middle of the upper surface of the hollow bottom plate. Tensile connecting rods are evenly arranged in the inner cavity of the control axis cylinder. One end of the tensile connecting rod away from the control axis cylinder is fixedly connected to an adjustment sleeve. Guide sliding plates are symmetrically arranged on the upper and lower sides of the outer surface of the adjustment sleeve. The guide sliding plates are made of metal and can horizontally slide along the upper surface of the hollow bottom plate under the magnetic force of the adsorption magnetic plate. Sliding pull rods are symmetrically arranged on the left and right sides of the inner wall of the adjustment sleeve. One end of the sliding pull rod away from the adjustment sleeve is fixedly connected to a shaping inner block. The shaping inner block is a square block-shaped component that can fill the four corners of the frame to achieve a shaping effect.

[0006] The side welding component includes an external housing. A receiving groove is formed in the inner cavity of the external housing. Corner insertion shells are evenly arranged at the four corners of the inner wall of the external housing through the receiving groove. A welding panel is fixedly connected to the middle of the inner cavity of the corner insertion shell. The welding panel can push the internal welding head to achieve the effect of changing the position of the welding head. Control wires are symmetrically arranged on both sides of the inner cavity of the corner insertion shell. One end of the control wire away from the corner insertion shell is fixedly connected to a control outer box, which is located at the position of the four corners of the outer side of the external housing facing the frame body.

[0007] Further, the stainless steel frame body includes a horizontal panel. Bent baffles are evenly fixed on the lower surface of the horizontal panel. After welding, the bent baffles around will be perpendicular to the horizontal panel and enclose the horizontal panel to form a usable metal frame body. The outer surface of the bent baffle is squeezed against the side surface of the shaping inner block, and the lower surface of the horizontal panel is squeezed against the upper surface of the shaping inner block.

[0008] The beneficial effect of the present invention is that when performing welding repair work through manual correction, since the stainless steel has a relatively high hardness, it is often impossible to make the horizontal panel form a right angle with all the bent baffles by manually squeezing the bent baffles. At this time, when performing the repair welding work, the finished tabletop may not be able to be buckled on the preset plane. When performing welding work through this device, shaping inner blocks can be filled at the four corners inside the stainless steel frame body, and the bent baffles around can be pressurized with the shaping inner blocks as a guide, ensuring that all the bent baffles can be welded in a vertical state against the horizontal panel, thereby avoiding welding defects and making it easier for the stainless steel frame body to be formed.

[0009] Further, the number of the support connecting rods is four. The top end of the support connecting rod is fixedly connected to the lower surface of the external housing. The bottom of the guiding sliding plate is slidably connected to the upper surface of the hollow bottom plate. The outer surface of the sliding pull rod is slidably connected to the inner wall of the adjustment sleeve. One end of the welding panel away from the corner insertion shell is squeezed against the side surface of the bent baffle through a sliding end. The outer surface of the control outer box is fixedly connected to the inner wall of the external housing through the receiving groove. One end of the control wire away from the control outer box is fixedly connected to the inner cavity of the welding head.

[0010] After adopting the above further structure, the device performs welding work on the gaps of the bent baffles through the corner insertion shells of the side welding component. Since the end of the welding panel can be telescopic and rotated within a certain range, the corner insertion shells can be fixed inside the external housing without moving, thus replacing manual welding work. And the welding head part is inside the external housing, which can be effectively protected, thereby extending the service life of the device. During welding, the welding fire can be blocked, thus avoiding the adverse phenomenon of welding sparks splashing.

[0011] Furthermore, the pressing component includes a downward pressing top plate. At the center of the lower surface of the downward pressing top plate, a compression connecting rod is fixedly connected. At the bottom end of the compression connecting rod, a control sliding shell is fixedly connected. Horizontally sliding plates are evenly arranged in the lower part of the inner cavity of the control sliding shell. One end of the horizontally sliding plate away from the control sliding shell is fixedly connected with a fine-tuning connecting cylinder. On both sides of the inner wall of the fine-tuning connecting cylinder, metal connecting rods slide symmetrically. One end of the metal connecting rod away from the fine-tuning connecting cylinder is fixedly connected with a socket pressing plate. Adjacent socket pressing plates can form a right-angle structure to shape the corner parts of adjacent bending baffles. The gap reserved between adjacent socket pressing plates can provide a working position for the welding end head.

[0012] Furthermore, the upper surface of the downward pressing top plate is fixedly connected to the ceiling through a fixing rod. The number of the horizontally sliding plates is four. The outer surface of the horizontally sliding plate is slidably connected to the inner cavity of the control sliding shell through a through slot. The top of the inner cavity of the socket pressing plate is fixedly connected to the outer surface of the metal connecting rod. The number of the socket pressing plates is eight. The outer surfaces of the socket pressing plates and the bending baffles are mutually extruded. The lower surface of the control sliding shell and the upper surface of the horizontal panel are mutually extruded.

[0013] After adopting the above further structure, during the debugging work, the fine-tuning connecting cylinder can push the metal connecting rods on both sides to extend, so that the socket pressing plates slide towards the side close to the bending baffle according to the actual size of the stainless steel frame, preventing the gap between adjacent socket pressing plates from being too large, resulting in the socket pressing plates being unable to effectively extrude the bending baffle, and thus the side of the stainless steel frame cannot be effectively extruded and the welding work is carried out in a warped state, resulting in serious quality problems.

[0014] Furthermore, the shaping inner block includes a square outer shell. On both sides of the inner cavity of the square outer shell close to the bending baffle, rubber soft pads are symmetrically arranged through through cutting grooves. On one side of the inner wall of the square outer shell close to the rubber soft pad, a pressure-sensitive element is fixedly connected. Drainage grooves are symmetrically opened on both sides of the inner cavity of the pressure-sensitive element close to the rubber soft pad. When the hollow rubber soft pad is extruded, it will pressurize the inner cavity of the pressure-sensitive element through the drainage groove, thereby representing that the rubber soft pad here is in contact with the inner wall part of the bending baffle. On the side of the inner wall of the square outer shell away from the pressure-sensitive element, a supporting inner block is fixedly connected. At the top of the inner cavity of the supporting inner block, a pressure-sensitive soft belt is fixedly connected. The pressure-sensitive soft belt can perform pressure sensing work on the upper surface of the square outer shell. The outer surface of the pressure-sensitive soft belt extends to the outside of the square outer shell, and the outer surface of the pressure-sensitive soft belt is mutually extruded with the lower surface of the horizontal panel. The inner wall of the rubber soft pad is fixedly connected to the outer surface of the pressure-sensitive element through the drainage groove. The lower surface of the square outer shell is fixedly connected to one end of the sliding pull rod away from the adjustment sleeve.

[0015] After adopting the above further structure, the device is provided with slidable direction shaping inner blocks at the four corners of the stainless steel frame body, so that there are shaping inner fixing components at the corner parts of the stainless steel frame body. Since the outer surface of the shaping inner block will be subjected to strong pressure due to the extrusion of the bending baffle, corresponding pressure sensing components are arranged on its three surfaces, so as to prevent the problem that the shaping inner block is damaged by extrusion due to excessive external pressure while ensuring that the bending baffle receives a large enough pressure.

[0027] The side welding component 2 includes an external housing 21, a receiving groove 22 is opened in the inner cavity of the external housing 21, corner plug housings 23 are evenly arranged at the four corners of the inner wall of the external housing 21 through the receiving groove 22, a welding panel 24 is fixedly connected to the middle of the inner cavity of the corner plug housing 23, the welding panel 24 can push the internal welding end to achieve the effect of changing the position of the welding end, control wires 25 are symmetrically arranged on both sides of the inner cavity of the corner plug housing 23, one end of the control wire 25 away from the corner plug housing 23 is fixedly connected to a control outer box 26, and the external housing 21 is located at the position of the four corners outside the frame.

[0028] The stainless steel frame 4 includes a horizontal panel 41, bending baffles 42 are evenly fixed on the lower surface of the horizontal panel 41. After welding, the surrounding bending baffles 42 will be perpendicular to the horizontal panel 41 to enclose the horizontal panel 41 to form a usable metal frame. The outer surface of the bending baffle 42 is squeezed against the side surface of the shaping inner block 5, and the lower surface of the horizontal panel 41 is squeezed against the upper surface of the shaping inner block 5.

[0029] The number of the supporting connecting rods 13 is four. The top ends of the supporting connecting rods 13 are fixedly connected to the lower surface of the external casing 21. The bottom of the guiding sliding plate 17 is slidably connected to the upper surface of the hollow bottom plate 11. The outer surface of the sliding pull rod 18 is slidably connected to the inner wall of the adjusting sleeve 16. One end of the welding panel 24 away from the corner socket 23 is pressed against the side surface of the bent baffle 42 through the sliding end. The outer surface of the control outer box 26 is fixedly connected to the inner wall of the external casing 21 through the accommodating groove 22. One end of the control wire 25 away from the control outer box 26 is fixedly connected to the inner cavity of the welding end.

[0030] Before using this device for work, first pull the pressurizing component 3 upwards, and then invert and buckle the roughly bent stainless steel frame 4 on the upper surface of the load-bearing component 1. At this time, the surrounding shaping inner blocks 5 will lift the inner wall of the horizontal panel 41 upwards, and then perform the following adjustment work:

[0031] The control axis cylinder 14 pulls the surrounding adjusting sleeves 16 by means of the propulsion tension connecting rod 15. At this time, the adjusting sleeves 16 slide along the upper surface of the hollow bottom plate 11 through the vertically arranged guiding sliding plates 17 on the outer surface, and then push the surrounding shaping inner blocks 5 towards the four corners of the stainless steel frame 4; for the upper pressurizing component 3, it cooperates with the load-bearing component 1 through the outer bent baffle 42 to perform the adjustment work, ensuring that the four-sided bent baffles 42 are laterally pressed towards the direction of fitting the outer surface of the shaping inner block 5, so that the stainless steel frame 4 maintains a complete and gapless frame structure with the square shaping inner block 5 as the reference.

[0032] After the adjustment is completed, weld the intersecting sides of the bent baffles 42 through the side welding component 2. The corner socket 23 spot-welds the bent baffles 42 through the internal welding panel 24. The welding panel 24 pushes the internal welding end towards the bent baffle 42, so that the welding end contacts the outer surface of the stainless steel frame 4, and then rotates the welding end to perform the full welding work. After the welding is completed, lift the pressurizing component 3, retract the welding end, and take out the stainless steel frame 4.

[0033] Example 2, please refer to Figures 1-7, the present invention provides a technical solution: on the basis of Embodiment 1, the pressing member 3 includes a downward pressing top plate 31, a compression connecting rod 32 is fixedly connected to the center of the lower surface of the downward pressing top plate 31, the bottom end of the compression connecting rod 32 is fixedly connected to a control sliding shell 33, horizontal sliding plates 34 are uniformly arranged in the lower part of the inner cavity of the control sliding shell 33, a fine-tuning connecting cylinder 35 is fixedly connected to one end of the horizontal sliding plate 34 away from the control sliding shell 33, metal connecting rods 36 are symmetrically slid on both sides of the inner wall of the fine-tuning connecting cylinder 35, a socket pressing plate 37 is fixedly connected to one end of the metal connecting rod 36 away from the fine-tuning connecting cylinder 35, adjacent socket pressing plates 37 can form a right-angle structure to perform shaping work on the corner parts of adjacent bending baffles 42, and the gap reserved by adjacent socket pressing plates 37 can provide a working position for the welding end.

[0034] The upper surface of the downward pressing top plate 31 is fixedly connected to the ceiling through a fixing rod. The number of the horizontal sliding plates 34 is four, and the outer surface of the horizontal sliding plate 34 is slidably connected to the inner cavity of the control sliding shell 33 through a through slot. The top of the inner cavity of the socket pressing plate 37 is fixedly connected to the outer surface of the metal connecting rod 36. The number of the socket pressing plates 37 is eight, the outer surfaces of the socket pressing plates 37 and the bending baffle 42 are mutually extruded, and the lower surface of the control sliding shell 33 and the upper surface of the horizontal panel 41 are mutually extruded.

[0035] The shaping inner block 5 includes a square outer shell 51. Rubber soft pads 52 are symmetrically arranged on both sides of the inner cavity of the square outer shell 51 close to the bending baffle 42 through through cutting grooves. A pressure-sensitive element 55 is fixedly connected to one side of the inner wall of the square outer shell 51 close to the rubber soft pad 52. Drainage grooves 56 are symmetrically opened on both sides of the inner cavity of the pressure-sensitive element 55 close to the rubber soft pad 52. When the hollow rubber soft pad 52 is extruded, it will pressurize the inner cavity of the pressure-sensitive element 55 through the drainage groove 56, thereby representing that the rubber soft pad 52 here contacts the inner wall part of the bending baffle 42. A support inner block 53 is fixedly connected to one side of the inner wall of the square outer shell 51 away from the pressure-sensitive element 55. A pressure-sensitive soft belt 54 is fixedly connected to the top of the inner cavity of the support inner block 53. The pressure-sensitive soft belt 54 can perform pressure-sensitive work on the upper surface of the square outer shell 51. The outer surface of the pressure-sensitive soft belt 54 extends to the outside of the square outer shell 51, and the outer surface of the pressure-sensitive soft belt 54 is mutually extruded with the lower surface of the horizontal panel 41. The inner wall of the rubber soft pad 52 is fixedly connected to the outer surface of the pressure-sensitive element 55 through the drainage groove 56. The lower surface of the square outer shell 51 is fixedly connected to one end of the sliding pull rod 18 away from the adjustment sleeve 16.

[0036] When performing debugging work, the top plate 31 is pressed down to press down the control slide housing 33 through the compression link 32. Then, the control slide housing 33 contracts the horizontal slide plates 34 around it, enabling the socket pressing plate 37 to squeeze the outer surface of the bending baffle 42. Then, the fine-tuning connecting cylinder 35 pushes the metal links 36 on both sides to extend. The socket pressing plate 37 slides towards the side close to the bending baffle 42. Then, the fine-tuning connecting cylinder 35 twists the metal links 36, causing the socket pressing plate 37 to squeeze towards the direction of fitting the bending baffle 42, thereby enabling all the bending baffles 42 to be perpendicular to the horizontal panel 41, and completing the shaping and fixing work of the bending baffle 42.

[0037] After the control slide housing 33 is pressed down, it will contact the upper surface of the horizontal panel 41. At this time, the square housing 51 that supports the horizontal panel 41 is squeezed, and then the pressure-sensitive soft belt 54 is pressed into the inside of the support inner block 53. Then, the compression link 32 stops stretching and pressurizing. Under the squeezing action of the socket pressing plate 37, both sides of the bending baffle 42 are closely attached to the outer surface of the square housing 51. At this time, the rubber soft pads 52 outside the square housing 51 are all flattened. Then, the inside of the pressure-sensitive element 55 is pressurized through the drainage groove 56 to trigger the pressure-sensitive element 55. At this time, the fine-tuning connecting cylinder 35 stops twisting the metal links 36, completing the debugging work.

[0038] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
