Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of firewall processing equipment, and in particular to a welding device for welding wire mesh frames and firewall panels. Background Technology
[0002] As is well known, fire-resistant fireproof panels are a common building material. They are made of specific fire-resistant materials and constructed into a panel structure. These panels are then used to build a wall, serving both as a building facade and as a fire-resistant barrier to prevent the spread of fire. However, these fire-resistant materials themselves lack rigidity. Therefore, to use them as firewalls in buildings, steel wire mesh frames are laid on both ends of the fire-resistant fireproof panel, with steel needles inserted. The two wire mesh frames are then welded together to firmly clamp the fire-resistant fireproof panel, using the rigidity of the wire mesh frames to compensate for the insufficient rigidity of the fire-resistant material.
[0003] Currently, welding between wire mesh frames and firewalls is generally divided into manual welding and mechanical welding. Manual welding involves inserting steel pins one by one and then welding them one by one with a welding clamp. Although this method can complete the welding work, it wastes a lot of manpower. While existing mechanical welding eliminates the need for manual welding, its mechanical design, in order to improve efficiency, often uses multiple sets of the same mechanism to perform batch work simultaneously. These mechanisms include welding clamp mechanisms and pin insertion mechanisms. However, existing mechanical welding equipment uses one drive mechanism per set of these mechanisms. When multiple sets of mechanisms are used, multiple drive mechanisms are required, which undoubtedly increases manufacturing costs and also adds weight to the equipment, making it more cumbersome. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welding device for welding wire mesh frames and firewalls, which uses a single drive to realize the linkage of multiple mechanisms.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A welding device for welding wire mesh frames and fireproof panels includes a main frame, which is provided with a guide channel for simultaneously feeding the wire mesh frame and the fireproof panel. The main frame is provided with a clamp for holding the wire mesh frame at the guide channel. Movable frames are installed on both sides of the main frame via a first linear module. The movable frames are driven by the first linear module to move away from or towards the guide channel. Each movable frame is provided with a pin insertion mechanism and a welding mechanism.
[0007] The pin insertion mechanism includes a first upright plate fixedly installed on a movable frame. The first upright plate has a material drop chamber that drops only one steel pin at a time, evenly arranged at one end near the material guide channel. The first upright plate has a material receiving channel below the material drop chamber, which is connected to the material drop port of the material drop chamber. A second upright plate is connected to the first upright plate via a slide rail and is provided with a first driver for pushing the second upright plate to move back and forth along the slide rail. The second upright plate has a number of pins corresponding to the material receiving channel, and the top of the pins is placed inside the material receiving channel.
[0008] The welding mechanism includes a first upright, a second upright, a third upright, and welding clamps evenly distributed on the first upright. The first upright is fixedly installed on the movable frame, and the first upright and the hinge point of the welding clamp form a hinge. The jaws of the welding clamp face the guide channel. One handle of each welding clamp is hinged to the second upright, and the other handle of each welding clamp is hinged to the third upright. The second and third uprights are respectively connected to a second driver through a hinge rod. The hinge rod is hinged to the second upright, the third upright, and the drive head of the second driver. The hinge holes on the second upright, the third upright, and the hinge rod are oblong holes.
[0009] Preferably, each of the feeding bins includes a hopper, the width of the feeding opening of the hopper allowing only a single steel needle to fall, and two opposing rollers shafted at the junction of the inner cavity of the hopper and the feeding opening. The rollers are provided with convex tooth surfaces, and one end of the rotating shaft of the rollers is placed outside the hopper. The first upright plate is provided with a third driver, and the driving head of the third driver is hinged to a fourth upright. The fourth upright is hinged to a number of swing arms corresponding to the number of rollers, and one end of the swing arms is fixedly connected to the corresponding roller. The hinge hole on the fourth upright is an oblong hole.
[0010] Preferably, there are at least two first drivers, which are symmetrically arranged on the first upright plate, and the drive heads of the first drivers are connected to the second upright plate.
[0011] Preferably, the clamp includes a square frame and a second linear module disposed on the upper and lower ends of the main frame. There are two square frames, which are respectively located on both sides of the material guide channel. The top and bottom ends of the square frames are respectively fixedly connected to the movable seats of the second linear module, and move repeatedly along the guiding direction of the material guide channel by the second linear module. The square frame is evenly provided with gripping members for gripping the wire mesh frame.
[0012] Preferably, the gripping member includes a base and a gripping block hinged to the base. A torsion spring is provided at the hinge between the gripping block and the base. Under the action of the torsion spring, the gripping block always tends to move closer to the wire mesh frame. The end of the gripping block faces the direction of feeding into the guide channel. A barb groove is provided on the inner end face of the gripping block. A conical surface is formed on the top of the gripping block. The conical surface communicates with the opening of the barb groove.
[0013] Preferably, the inner end face of the gripping block is further provided with a transverse clearance groove.
[0014] By adopting the above solution, this utility model not only meets the requirements for automated welding of steel wire mesh and fireproof panels, but also enables the uniform insertion of steel needles and the uniform opening and closing of welding clamps with a small number of drivers, effectively reducing the number of drivers used, making the structure simpler, reducing manufacturing costs, and further reducing the overall weight.

[0025] like Figures 1 to 3 As shown in the figure, this embodiment provides a welding device for welding wire mesh frames and fireproof panels, including a main frame 1. The main frame 1 is provided with a guide channel 2 for simultaneously feeding wire mesh frames and fireproof panels. The main frame 1 is provided with a clamp 3 for clamping the wire mesh frame at the guide channel 2. Movable frames 5 are installed on both sides of the main frame 1 at the guide channel 3 through a first linear module 4. The movable frames 5 are driven by the first linear module 4 to move away from or towards the guide channel 2. Each movable frame 5 is provided with a pin insertion mechanism 6 and a welding mechanism 7.
[0026] The needle insertion mechanism 6 includes a first upright plate 61 fixedly installed on the movable frame 5. The first upright plate 61 has a material drop chamber 62 evenly arranged at one end near the material guide channel 2, which will drop only one steel needle at a time. The first upright plate 61 is provided with a receiving channel 63 below the material drop chamber 62. The receiving channel 63 is connected to the material drop port of the material drop chamber 62. The first upright plate 61 is connected to a second upright plate 64 through a slide rail 8 and is provided with a first driver 65 for pushing the second upright plate 64 to move back and forth along the slide rail 8. The second upright plate 64 is provided with a number of ejector pins 66 corresponding to the number of receiving channels 63. The top of the ejector pins 66 is placed in the receiving channel 63.
[0027] The welding mechanism 7 includes a first upright 71, a second upright 72, a third upright 73, and welding clamps 74 evenly distributed on the first upright 71. The first upright 71 is fixedly installed on the movable frame 5. The hinge point between the first upright 71 and the welding clamps 74 forms a hinge. The jaws of the welding clamps 74 face the material guide channel 2. One handle of each welding clamp 74 is hinged to the second upright 72, and the other handle of each welding clamp 74 is hinged to the third upright 73. The second upright 72 and the third upright 73 are respectively connected to the second driver 76 via a hinge rod 75. The hinge rod 75 is connected to the second upright 72, the third upright 73 and the drive head of the second driver 76 via hinges. In order to meet the requirements of the rotation of the handle of the welding clamp 74, the hinge holes on the second upright 72, the third upright 73 and the hinge rod 75 are oblong holes, which can meet the arc movement of micro distance. The specific shape of the oblong hole is determined according to the trend of the movement of the handle of the welding clamp 74.
[0028] During the welding process, after the wire mesh frame and the firewall plate are bonded together (hereinafter, the product formed by bonding the wire mesh frame and the firewall plate together is defined as material 100), it is inserted from one end of the guide channel 2. When material 100 moves to the first pin insertion mechanism 6, the advancement stops. At this time, the clamp 3 located at the inlet of the guide channel 2 supports material 100, and the first pin insertion mechanism 6 begins to work. When the pin insertion mechanism 6 works, the first linear module 4 moves the movable frame 5 closer to material 100, that is, moves the receiving channel 63 closer to the material. Then, the first driver 65 drives the second upright plate 64 to move. The ejector pin 66 on the second upright plate 64 pushes out the steel needle in the receiving channel 63 and inserts it into material 100 until the tip of the steel needle passes through material 100 and is placed at the other end of material 100. According to the layout, one of the welding mechanisms 7 on the other side of the movable frame 5 is just at the position where the steel needle is inserted. At this time, the pin insertion mechanism 6 remains stationary, and part of the steel needle is still in the receiving channel 63 (so that it can be used before welding). (At the moment of connection, it plays a supporting role). Then, the first welding mechanism 7 begins the welding work. When the welding work begins, the second driver 76 starts working, opening the jaws of the welding clamp 74. Under the action of the first linear module 4, the jaws of the welding clamp 74 are positioned at the steel needle and the wire mesh frame. Then, after the second driver 76 retracts, the welding clamp 74 closes, clamping the steel needle and the wire mesh frame. Then, the welding is carried out by the welding clamp 74 itself based on the principle of welding (the main principle is the heat generated when current passes through a metal conductor). The welding process involves melting the metal (to achieve welding) and welding the wire mesh frame and steel needles. After welding, the welding clamp 74 remains open, and the first driver 65 of the needle insertion mechanism 6, which was originally stationary, retracts. The first linear module 4 also retracts accordingly. Steel needles that were previously partially stuck in the receiving channel 63, having already been welded to the wire mesh frame at one end, are completely removed from the receiving channel 63. After the ejector pin 66 retracts, the dropping bin 62 resumes discharging the next steel needle, ready for the next needle insertion operation. As the material 100 continues to be pushed, any unwelded portions of the steel needles are finished by the welding mechanism 7 on the same side. Of course, to accelerate welding efficiency, multiple needle insertion mechanisms 6 and corresponding welding mechanisms 7 can be set up, with the same working principle.
[0029] Furthermore, regarding the specific structure of the feeding bin 62, each feeding bin 62 in this embodiment includes a hopper 621. The width of the feeding port 622 of the hopper 621 is only wide enough to allow a single steel needle to fall. At the junction of the inner cavity of the hopper 621 and the feeding port 622, two opposing rollers 623 are axially connected. The rollers 623 are provided with convex tooth surfaces 624. One end of the rotating shaft of the rollers 623 is placed outside the hopper 621. The first upright plate 61 is provided with a third driver 625. The driving head of the third driver 625 is hinged to a fourth upright rod 626. The fourth upright rod 626 is hinged to a number of swing rods 627 corresponding to the number of rollers 623. One end of the swing rod 627 is fixedly connected to the corresponding roller 623. The hinge hole on the fourth upright rod 626 is an oblong hole. Because the width of the discharge port 622 is set so that only steel needles are placed in the discharge port 622 in a stacked form, when the ejector pin 66 has not retracted, it will resist the bottom steel needle and not fall. After the ejector pin 66 retracts, it provides space for a single steel needle to fall. This achieves the setting of only a single steel needle falling. In order to avoid the steel needles from being suspended when they accumulate in the discharge bin 62 and not falling automatically, a roller 623 that can provide a stirring effect is set. It is mainly to facilitate the driving of the third driver 625. The oscillating roller 623 oscillates back and forth (not rotates 360°) so that the steel needles fall smoothly into the discharge port 622.
[0030] Furthermore, since the first upright plate 61 has a relatively long span, if a single driver is used to drive it, there may be an imbalance in the force. Therefore, in this embodiment, there are at least two first drivers 65 (generally, two are sufficient to meet the requirements). The first drivers 65 are symmetrically arranged on the first upright plate 61, and the drive heads of the first drivers 65 are connected to the second upright plate 64.
[0031] Furthermore, regarding the specific structure of the clamp 3, the clamp 3 in this embodiment includes a square frame 31 and a second linear module 32 disposed on the upper and lower ends of the main frame 1. There are two square frames 31, located on opposite sides of the guide channel 2. The top and bottom ends of each square frame 31 are fixedly connected to the movable seats of the second linear module 32, and move repeatedly along the guiding direction of the guide channel 2 by the second linear module 32. The square frame 31 is evenly provided with gripping members 33 for gripping the wire mesh frame, and... The gripper 33 includes a base 331 and a gripping block 332 hinged to the base 331. A torsion spring 333 is provided at the hinge between the gripping block 332 and the base 331. Under the action of the torsion spring 333, the gripping block 332 tends to press against the wire mesh frame. The end of the gripping block 332 faces the feeding direction of the guide channel 2. A barb groove 334 is provided on the inner end face of the gripping block 332, and a conical surface 335 is formed at the top of the gripping block 332. The conical surface 335 communicates with the groove opening of the barb groove 334. With this configuration, the clamp 3 not only serves to hold the material 100 but also to push the material 100, avoiding subsequent manual pushing. In actual operation, the torsion spring 333 on the gripper 33 is set to allow the gripper block 332 to automatically avoid the second linear module 32 when it retracts, so that the gripper 332 does not grip. When the second linear module 32 moves along the discharge direction of the guide channel 2, it hooks the wire on the wire mesh frame with the barbed groove 334. Then, driven by the second linear module 32, the material 100 can move as a whole. In order to make the gripping block 332 grip the wire mesh frame more stably, the study found that the most stable gripping effect is at the cross intersection of the wires of the wire mesh frame. However, there are horizontal wires at the cross intersection, which will form an obstacle. Since the barbed groove 334 only hooks the vertical wires, a horizontal clearance groove 336 is also provided on the inner end face of the gripping block. The horizontal clearance groove 336 can allow the horizontal wires to be inserted into the horizontal clearance groove 336, so as not to affect the barbed groove 334 from hooking the vertical wires.
[0032] Furthermore, the actuator in this embodiment can be a cylinder, but other actuators can also be used as long as they can satisfy the telescopic function.
[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
