Description

Technical Field

[0001] This invention relates to the field of cement floor decking technology, specifically to a welding forming machine, a cement floor decking production line, and a production method. Background Technology

[0002] In the construction industry, floor decking structures are becoming increasingly widely used. While steel truss floor decking has mature production technology, its application is limited due to the inability to integrate the metal base plate with subsequent decoration. It is generally only used in steel structure industrial buildings or large open-plan commercial buildings. Cement floor decking has successfully overcome this drawback of steel truss floor decking and is receiving increasing attention with the development of green building and prefabricated building.

[0003] However, existing cement decking production processes are cumbersome and have low automation and production efficiency. The following problems exist in the publicly disclosed cement decking production technology: 1. Cement decking assembly connections only use bolts or screws, requiring multiple drilling operations in large quantities, placing extremely high demands on production equipment performance, resulting in high equipment costs and low efficiency, directly impacting production costs; 2. Bolt or screw connections require a production process with the bottom formwork on top and the reinforcing steel bars below, necessitating later flipping of the components. This process involves bulky, cumbersome, and expensive equipment, leading to high production costs and low efficiency; 3. While traditional floor decking production uses welding connections for convenience, the equipment requires electrodes at both the top and bottom, making it unsuitable for cement decking production; 4. Existing steel plate composite cement decking, while overcoming the drawbacks of traditional bolt or screw connections through welding, suffers from low production efficiency due to the lack of supporting automated welding equipment, hindering its development.

[0016] Equipment for automatically unloading and storing finished components.

[0017] Preferably, the automatic welding and forming equipment for cement floor decking also includes a robotic arm for clamping the welding equipment.

[0018] This invention also proposes a method for producing cement floor decking, comprising the following steps:

[0019] S1: Based on the production plan and the size of the steel mesh and steel truss, the intelligent assembly equipment for steel mesh and steel truss automatically selects the pick-up position of the steel mesh and steel truss, and positions and assembles the steel mesh and steel truss.

[0020] S2: The automatic welding and forming machine for steel mesh and steel truss intelligently identifies the specifications and models of the steel bars to be welded in the production plan, automatically adjusts the welding current and welding time, and automatically judges the spacing of the steel bars and welds the steel mesh to the connection point of the truss steel bars to form a steel skeleton.

[0021] S3: The intelligent assembly equipment for cement floor decking can automatically select the picking position according to the production plan and the size of the steel reinforcement cage and the bottom formwork of the floor decking, and position and assemble the bottom formwork of the floor decking and the steel reinforcement cage to form cement floor decking components.

[0022] S4: The intelligent conveyor in the automatic welding and forming equipment for cement floor decking automatically determines the spacing of the reinforcing bars according to the production plan and accurately conveys the connection point of the reinforcing bar skeleton and the bottom mold of the floor decking to the automatic welding equipment for welding. The welding and forming machine adopts the method of setting both positive and negative poles above the bottom mold of the floor decking or adopts the method of using a robotic arm to hold the welding equipment to weld the reinforcing bar skeleton and the bottom mold of the floor decking to form finished cement floor decking components.

[0023] S5: Then the finished components are automatically removed from the production line by the finished component unloading and warehousing equipment, thus completing the production of cement floor decking.

[0024] Preferably, in step S4, the welding method of the welding forming machine includes: first, the negative electrode contacts the bottom mold of the floor deck and is located on one side of the reinforcing steel skeleton; then, as the positive and negative electrodes press down, the positive electrode makes close contact with the upper end of the reinforcing steel skeleton and achieves the pressing of the reinforcing steel skeleton and the bottom mold of the floor deck; the negative electrode makes close contact with the bottom mold of the floor deck; and the welding forming machine is energized to complete the welding of the reinforcing steel skeleton and the bottom mold of the floor deck.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. This invention uses a welding process, eliminating the need for bolts or screws and drilling. The welding equipment is simple.

Detailed Implementation

[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] Example 1

[0047] like Figure 1-4 As shown, this embodiment proposes a welding forming machine, including a positive electrode 1 and a negative electrode 2 both disposed on the upper part of the workpiece. The negative electrode 2 is disposed on one side of the positive electrode 1 and / or disposed inside the positive electrode 1 and / or disposed on both sides of the positive electrode 1.

[0048] like Figure 1 As shown, it also includes a positive copper column 3, with a positive electrode 1 connected to the bottom end of the positive copper column 3; a negative copper column 4 is provided on one side of the positive copper column 3, and the negative copper column 4 is connected to the negative electrode 2. The negative copper column 4 is also fitted with a spring 5. The bottom end of the spring 5 is fixedly connected to the negative electrode 2 and / or the negative copper column 4, and the upper end of the spring 5 is fixedly connected to a fixing block, which is fixedly connected to the main body of the welding forming machine. Thus, under the action of the spring 5, the negative electrode 2 drives the negative copper column 4 to move freely in the vertical direction, so that the bottom surface of the positive electrode 1 and the bottom surface of the negative electrode 2 form a plane.

[0049] Spring 5 ensures that positive electrode 1 can smoothly fall and compact the workpiece after negative electrode 2 is connected. Positive electrode copper pillar 3 has a hollow internal structure with an insulating inner wall. This positive and negative electrode arrangement allows for relatively flexible adjustment of the distance between the positive and negative electrodes, facilitating welding operations.

[0050] like Figure 4 The setting method described is the same as Figure 1 The setup methods are the same, the difference is that... Figure 4 In the aforementioned configuration, two negative copper pillars 4 are symmetrically arranged on both sides of the positive copper pillar 3. This configuration allows for relatively flexible adjustment of the distance between the positive and negative poles, while expanding the welding range, forming an effective circuit between the positive and negative poles, shortening the current travel distance, and facilitating welding operations over a larger area.

[0051] like Figure 2 As shown, it also includes a positive copper column 3 with an internal cavity, and a positive electrode 1 connected to the bottom end of the positive copper column 3; a negative copper column 4 is disposed inside the positive copper column 3, and the negative copper column 4 is connected to the negative electrode 2. A spring 5 is also fitted onto the negative copper column 4. The bottom end of the spring 5 is fixedly connected to the negative electrode 2 and / or the negative copper column 4, and a fixing block is fixedly connected to the upper end of the spring 5. This fixing block is fixedly connected to the inner wall of the positive copper column 3, so that under the action of the spring 5, the negative electrode 2 drives the negative copper column 4 to move freely along the length direction of the positive copper column 3, thereby forming a plane between the bottom surface of the positive electrode 1 and the bottom surface of the negative electrode 2. The spring 5 is made of insulating material.

[0052] The positive electrode copper pillar 3 has a hollow internal structure with an insulating inner wall, which wraps around the outside of the negative electrode copper pillar 4, thus creating a gap between the positive electrode copper pillar 3 and the negative electrode copper pillar 4. This positive and negative electrode arrangement allows for a more concentrated welding range, making it suitable for small-scale welding work. It also results in better welding quality, with no residual impurities that affect the normal performance of the workpiece.

[0053] like Figure 3 The device also includes a negative electrode copper column 4 with an internal cavity, and a negative electrode 2 is connected to the bottom end of the negative electrode copper column 4; a positive electrode copper column 3 is disposed inside the negative electrode copper column 4, and a positive electrode 1 is connected to the bottom end of the positive electrode copper column 3; the positive electrode 1 and the negative electrode 2 are rotatably connected.

[0054] The negative electrode 2 is symmetrically arranged on both sides of the positive electrode 1. The positive electrode 1 is also connected to the negative electrode 2 through a spring 5. The spring 5 is set in an inclined direction. An insulating sheet is also provided between the positive electrode 1 and the negative electrode 2.

[0055] The positive electrode 1 is connected to two ends by a first connecting plate 7. The bottom end of the positive electrode 1 is also rotatably connected to a symmetrically arranged second connecting plate 8 via a rotating shaft 6. The first connecting plate 7 is positioned above the second connecting plate 8, and the other end of the second connecting plate 8 is connected to the negative electrode 2. An insulating sheet can be provided at the connection between the second connecting plate 8 and the negative electrode 2; the insulating sheet can also be the first connecting plate 7 and / or the second connecting plate 8. The insulating sheet is used for the isolation between the positive electrode 1 and the negative electrode 2.

[0056] The first connecting plate 7 is connected to the second connecting plate 8 by a spring 5 set in an inclined direction. Thus, when the positive electrode 1 drives the positive electrode copper column 3 to move vertically under the action of the spring 5, the second connecting plate 8 will rotate. At this time, under the action of the first connecting plate 7, the spring 5 is compressed, so that the bottom surface of the positive electrode 1 and the bottom surface of the negative electrode 2 form a plane.

[0057] In the above four positive and negative electrode settings, in the initial state, the bottom surface of positive electrode 1 is higher than the bottom surface of negative electrode 2, so that both positive and negative electrodes can be in close contact with the workpiece.

[0058] The welding process proposed in this invention changes the position of the electrodes, adopting a negative electrode top-mounted design. The positive and negative electrodes required for welding are both placed on the upper part of the workpiece, forming a welding circuit. During welding, the current passes through the upper positive electrode copper pillar 3 (which is pressed by mechanical force to ensure full contact between the steel bar and the steel plate). Utilizing the resistance effect of the workpiece, a large current flows through the workpiece to the negative electrode 2, generating a large amount of heat at the workpiece contact surface, causing it to melt instantly. Under the action of external force, the two can be firmly fused together, reducing production and equipment costs and shrinking the production line, thus saving production space.

[0059] Example 2

[0060] like Figure 5-10 As shown, this embodiment proposes a cement floor decking production line, including steel mesh and steel truss intelligent assembly equipment;

[0061] Automatic welding forming machine for steel mesh and steel truss used to weld steel mesh and steel truss to form a steel skeleton;

[0062] Intelligent assembly equipment for cement floor decking used for assembling steel reinforcement cages and floor decking bottom formwork;

[0063] An automatic welding and forming equipment for cement floor decking includes an intelligent conveyor and a welding forming machine as described in Example 1. The welding forming machine is used for welding the steel reinforcement cage and the bottom formwork of the floor decking.

[0064] Automated transport and transfer tracks for components and automated unloading and warehousing equipment for finished components.

[0065] Through technological innovation and collaborative operation of multiple sets of equipment, a welding process for connecting cement floor deck slabs has been realized, replacing bolt or screw connections with welding connections and eliminating multiple cumbersome processes such as drilling and screwing. Furthermore, a production process with the bottom formwork below and the steel reinforcement skeleton above has been successfully implemented, eliminating the need for subsequent flipping, thus improving production efficiency, reducing production and equipment costs, and shrinking the production line to save production space.

[0066] The intelligent assembly equipment for steel mesh and steel trusses includes a set of hoisting tracks, a set of steel mesh assembly robots, and a set of steel truss assembly robots. The hoisting tracks, through intelligent CNC and positioning devices, precisely guide the assembly robots to the appropriate positions for picking and assembling. The steel mesh assembly robots automatically select pick-up positions and position and assemble the mesh according to the production plan and mesh size. The steel truss assembly robots automatically select pick-up positions and position and assemble the mesh according to the production plan and truss size. The two sets of robots can be controlled by the hoisting tracks to achieve alternating, continuous assembly, greatly improving production efficiency.

[0067] The automatic welding and forming machine for steel reinforcement cages includes a set of intelligent conveying equipment and a set of automatic welding equipment. The intelligent conveying equipment automatically determines the spacing of the steel bars according to the production plan and accurately conveys the steel mesh to the connection points of the truss reinforcement to the automatic welding equipment for welding. The automatic welding equipment intelligently identifies the specifications and models of the steel bars to be welded in the production plan and automatically adjusts the welding current and welding time to ensure welding quality.

[0068] The intelligent assembly equipment for cement floor decking includes a set of hoisting tracks, a set of intelligent robotic arms, and a set of adjustable suction cups. The hoisting tracks allow the intelligent CNC and positioning devices to precisely deliver the assembly robotic arms and suction cups to the relevant positions for picking and assembling. The intelligent robotic arms can automatically select the picking position according to the production plan and the size of the reinforcing steel frame and the floor decking bottom formwork, and then position and assemble the floor decking bottom formwork and reinforcing steel frame.

[0069] A set of adjustable suction cups consists of multiple rectangular strip-shaped smaller suction cups (a set of adjustable suction cups also includes multiple circular suction cups) positioned under a large suction cup. The equipment can intelligently adjust the number of suction cups used based on the base plate size, according to the production plan. Then, the lifting track coordinates with the equipment to pick up the suction cups and assemble them in the optimal lifting position. A set of intelligent robotic arms and a set of adjustable suction cups can be controlled by a lifting track to achieve alternating, continuous assembly, greatly improving production efficiency.

[0070] The automatic welding and forming machine for cement floor decking includes a set of intelligent conveying equipment and a set of automatic welding equipment. The intelligent conveying equipment can automatically determine the spacing between adjacent steel reinforcement cages according to the production plan and accurately convey the connection points of the steel reinforcement cages and the bottom formwork of the floor decking to the automatic welding equipment for welding.

[0071] An automated welding system was developed to adapt to the welding process requirements of cement floor decking. It features a modified electrode design with the negative electrode positioned on top, and can automatically adjust the current and welding time based on the type of reinforcing bar and steel plate to ensure weld strength. The negative electrode top-positioning design places both the positive and negative electrodes above the workpiece, forming a welding circuit. During welding, current flows through the upper positive electrode copper pillar (pressed by mechanical force to ensure full contact between the reinforcing bar and steel plate). Utilizing the workpiece's resistance, a larger current flows through the workpiece to the negative electrode, generating significant heat at the contact surface, causing it to melt instantly. Under external force, the two parts are firmly fused together, achieving a stable and reliable welded connection.

[0072] like Figure 8 First, the steel mesh 11 and steel truss 10 (hereinafter referred to as the steel skeleton) are positioned and assembled by intelligent assembly equipment for steel mesh and steel truss. The steel skeleton is then welded together using an automatic welding forming machine. This welding method can utilize conventional welding techniques. Next, intelligent assembly equipment for cement floor decking slabs assembles the floor decking bottom formwork 9 with the steel skeleton to form a cement floor decking component. Then, an automatic welding forming machine for cement floor decking slabs welds the steel skeleton to the floor decking bottom formwork 9. This welding method requires the welding forming machine described in Example 1 to form the finished cement floor decking component. Finally, the finished component is automatically removed from the production line by an automated warehousing equipment. All transportation and transfer during the production process are completed by an automated component transport transfer track.

[0073] The welding method for the welding forming machine and the reinforcing steel frame described in Example 1 can employ either resistance welding equipment or robotic welding equipment. The resistance welding equipment uses a negative electrode top-mounted design, as shown in the following description. Figure 1-4 The positive electrode 1 is pressed against the steel truss reinforcement, and the negative electrode 2 is pressed against the bottom formwork 9 of the floor slab. The robotic welding equipment uses MIG welding and other methods for automated positioning welding.

[0074] This example also proposes a method for producing cement floor decking, including the following steps:

[0075] S1: According to the production plan and the size of the steel mesh 11 and steel truss 10, the intelligent assembly equipment for steel mesh and steel truss automatically selects the picking position of steel mesh 11 and steel truss 10, and positions and assembles steel mesh 11 and steel truss 11.

[0076] S2: The automatic welding forming machine for steel mesh and steel truss intelligently identifies the specifications and models of the steel bars to be welded in the production plan, automatically adjusts the welding current and welding time, and automatically judges the spacing of the steel bars and welds the connection point of the steel mesh 11 and the truss steel bar 10 to form a steel skeleton.

[0077] S3: The intelligent assembly equipment for cement floor decking can automatically select the picking position according to the production plan and the size of the steel reinforcement cage and the bottom mold 9 of the floor decking, and position and assemble the bottom mold 9 of the floor decking and the steel reinforcement cage to form cement floor decking components.

[0078] S4: The intelligent conveyor in the automatic welding and forming equipment for cement floor decking automatically determines the spacing of the reinforcing bars according to the production plan and accurately conveys the connection point of the reinforcing bar skeleton and the bottom mold 9 of the floor decking to the automatic welding equipment for welding. The welding and forming machine adopts a method in which both positive and negative poles are set above the bottom mold 9 of the floor decking to weld and connect the reinforcing bar skeleton and the bottom mold 9 of the floor decking to form finished cement floor decking components.

[0079] S5: Then the finished components are automatically removed from the production line by the finished component unloading and warehousing equipment, thus completing the production of cement floor decking.

[0080] It should be noted that after the steel mesh and steel truss are welded together, they form a steel skeleton. The steel skeleton is then welded to the bottom formwork of the floor deck to form the finished cement floor deck component.

[0081] In step S4, the welding method of the welding forming machine includes: first, the negative electrode 2 contacts the bottom mold 9 of the floor deck and is located on one side of the steel reinforcement cage; then, as the positive and negative electrodes press down, the positive electrode 1 makes close contact with the upper end of the steel reinforcement cage and achieves the pressing of the steel reinforcement cage and the bottom mold 9 of the floor deck; the negative electrode 2 makes close contact with the bottom mold 9 of the floor deck; and the welding forming machine is energized to complete the welding of the steel reinforcement cage and the bottom mold 9 of the floor deck.

[0082] The welding method is as follows: Figure 5 The negative electrode 2 is located at the first negative electrode placement area 13, and the positive electrode 1 is located at the positive electrode placement area 16. Under the action of the positive electrode copper column 3, the steel truss 10 in the steel reinforcement skeleton can fully contact the bottom formwork 9 of the floor deck and achieve the pressing work. Utilizing the resistance effect of the workpiece, a large current flows through the workpiece to the negative electrode 2, generating a lot of heat on the contact surface of the workpiece, causing it to melt instantly. Under the action of external force, the two can be firmly fused together, thereby completing the welding work of the steel reinforcement skeleton and the bottom formwork 9 of the floor deck.

[0083] In step S4, the welding method of the welding forming machine includes: firstly, the negative electrode 2 is located in the gap of the steel reinforcement skeleton and is in contact with the bottom mold 9 of the floor deck. Then, as the positive and negative electrodes press down, the positive electrode 1 is in close contact with the upper end of the steel reinforcement skeleton. The positive electrode 1 realizes the pressing work between the steel reinforcement skeleton and the bottom mold 9 of the floor deck. The negative electrode 2 is in close contact with the bottom mold 9 of the floor deck. The welding forming machine is powered on to complete the welding work between the steel reinforcement skeleton and the bottom mold 9 of the floor deck.

[0084] The welding method is as follows: Figure 6The negative electrode 2 is located at the second negative electrode placement area 14, and the positive electrode 1 is located at the positive electrode placement area 16. Under the action of the positive electrode copper column 3, the steel truss 10 in the steel reinforcement skeleton can fully contact the bottom formwork 9 of the floor deck and achieve the pressing work. This arrangement facilitates the pressing of the positive electrode copper column 3 while shortening the distance between the positive electrode 1 and the negative electrode 2, preventing current deviation. By utilizing the resistance effect of the workpiece, a large current flows through the workpiece to the negative electrode 2, generating a lot of heat at the contact surface of the workpiece, causing it to melt instantly. Under the action of external force, the two can be firmly fused together, thereby completing the welding work of the steel reinforcement skeleton and the bottom formwork 9 of the floor deck.

[0085] In step S4, the welding method of the welding forming machine includes: firstly, the negative electrode 2 is symmetrically arranged on both sides of the steel reinforcement skeleton and in contact with the bottom mold 9 of the floor deck. Then, as the positive and negative electrodes press down, the positive electrode 1 is in close contact with the upper end of the steel reinforcement skeleton. The positive electrode 1 realizes the pressing work between the steel reinforcement skeleton and the bottom mold 9 of the floor deck. The negative electrode 2 is in close contact with the bottom mold 9 of the floor deck. The welding forming machine is powered on to complete the welding work between the steel reinforcement skeleton and the bottom mold 9 of the floor deck.

[0086] The welding method is as follows: Figure 7 The negative electrode 2 is located at the third negative electrode placement area 15, and the positive electrode 1 is located at the positive electrode placement area 16. Under the action of the positive electrode copper column 3, the steel truss 10 in the steel reinforcement skeleton can fully contact the bottom formwork 9 of the floor deck and achieve the pressing work. There are two first negative electrode placement areas 13. This welding method can achieve better contact between the steel truss 10 and the bottom formwork 9 of the floor deck, and the current of the positive electrode 1 flows to the two negative electrode 2 positions respectively, which can achieve full welding work and better welding quality. Utilizing the resistance effect of the workpiece, a large current flows through the workpiece to the negative electrode 2, generating a lot of heat at the contact surface of the workpiece, causing it to melt instantly. Under the action of external force, the two can be firmly fused together, thereby completing the welding work of the steel reinforcement skeleton and the bottom formwork 9 of the floor deck.

[0087] This invention also proposes, for example... Figure 4 The aforementioned welding method, taking into account... Figure 7 In actual operation, the positions of the positive and negative electrodes may be inconvenient to adjust, making it difficult to guarantee the contact performance between the positive and negative electrodes and the bottom formwork 9 of the floor deck slab. Therefore, the negative electrode 2 can also be symmetrically arranged on both sides of the positive electrode 1. In this arrangement, the negative electrode 2 is located at the third negative electrode placement area 15, and the positive electrode is located at the positive electrode placement area 16, which differs from the previous arrangement. Figure 3 The welding method changes the connection between the positive and negative electrodes, but does not change the placement area of ​​the positive and negative electrodes on the bottom formwork 9 of the floor deck. Therefore, the operation is more convenient and more in line with actual welding needs. It is low in cost, highly reliable, and has a higher safety factor.

[0088] like Figure 10 In this invention, a robotic arm 17 can also be used to hold the welding equipment. The robotic arm 17 is used to perform automated welding by using the welding equipment in the form of MIG welding or similar methods. The robotic arm 17 is positioned above the workpiece. By adjusting the end of the welding head, the robotic arm 17 can perform welding in various ways.

[0089] In this invention, welding is used instead of bolts or screws, eliminating the need for drilling. The welding equipment is simple. This production process uses the steel truss and steel mesh as a whole and welds them together on the same bottom template. The process does not require a flip-plate process, resulting in low production costs, high production efficiency, good fire resistance, and reliable connection performance.
