Description

Technical Field

[0001] The present application relates to the field of welding equipment, and in particular to a fully automatic double steel bar flat welding machine. Background Art

[0002] Reinforced concrete is a load-bearing material commonly used in buildings. At present, most of the reinforcement in reinforced concrete is hot-rolled steel bars. It is well known that the strength of hot-rolled low-carbon steel after cold drawing is 50% higher than that of hot-rolled steel. If the steel bars in reinforced concrete are replaced with cold-drawn steel wires, a large amount of steel will be saved. However, due to the smooth surface of cold-drawn steel wires, the concrete has poor grip on the steel wires, which hinders the application of cold-drawn steel wires in reinforced concrete.

[0003] Therefore, a steel bar structure (ladder-shaped, referred to as "double steel bar") with horizontal wires welded between two parallel cold-drawn steel wires appeared. That is, horizontal wires are welded at a set equal distance between two longitudinal steel wires that are close to each other (20mm), and a ladder-like structure is formed by the longitudinal and transverse steel wires. The application of double steel bars in reinforced concrete not only makes up for the problem of insufficient holding power of cold-drawn steel wires in concrete, but also saves a lot of steel, eliminating obstacles for the application of cold-drawn steel wires in reinforced concrete, and forming a new type of reinforced concrete structure.

[0004] The inventor found that the existing double steel bar automatic flat welding machine transmission system uses a large number of cam structures (the welding process is generally: longitudinal reinforcement feeding → transverse reinforcement feeding → longitudinal reinforcement stopping → transverse reinforcement loading → welding → reciprocating). During welding, the longitudinal reinforcement is in a static state, and the entire welding process is an intermittent reciprocating motion, which not only seriously restricts production efficiency, but also has a series of technical problems such as high noise, low precision, and poor reliability.

[0005] Therefore, the inventor, relying on many years of experience and practice in related industries, proposes a fully automatic double steel bar flat welding machine to overcome the defects of the prior art. Summary of the invention

[0006] In response to the problems in the prior art, the present application provides a fully automatic double steel bar flat welding machine that can automatically, accurately and conveniently complete the double steel bar welding work, thereby improving the work efficiency and reliability of double steel bar welding.

[0014] Furthermore, it also includes a front straightening roller group arranged on the chassis body, and the longitudinal ribs pass through the front straightening roller group to determine the feeding direction.

[0015] Furthermore, the motor of the transmission device is connected to the main gear, and the main gear is transmission-connected to a first sub-gear, and the first sub-gear is used to drive the front active feed roller and the front passive feed roller arranged on both sides of the longitudinal ribs, so that the front active feed roller and the front passive feed roller drive the longitudinal ribs to move.

[0016] Furthermore, the main gear of the transmission device is also connected to a second sub-gear, and the second sub-gear is used to drive the rear active feed roller and the rear passive feed roller arranged on both sides of the double steel bars, so that the rear active feed roller and the rear passive feed roller drive the double steel bars obtained after welding to move.

[0017] Furthermore, the main gear of the transmission device is also transmission-connected to a third sub-gear, and the third sub-gear is synchronously connected to a first set of synchronous pulleys and a second set of synchronous pulleys. The first set of synchronous pulleys is used to drive the automatic welding mechanism to rotate, and the second set of synchronous pulleys is used to drive the automatic feeding mechanism to rotate.

[0018] Furthermore, the first sub-gear, the second sub-gear and the third sub-gear rotate synchronously.

[0019] Furthermore, it also includes a PLC controller arranged in the chassis body, and the PLC controller is electrically connected to the motor of the transmission device, the welding head of the automatic welding mechanism, and the front straightening roller group and the rear straightening roller group.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] Considering that the existing double-rebar automatic flat welding machine transmission system adopts a large number of cam structures (the welding process is generally: longitudinal reinforcement feeding → transverse reinforcement feeding → longitudinal reinforcement stopping → transverse reinforcement loading → welding → reciprocating), the longitudinal reinforcement is in a static state during welding, and the entire welding process is an intermittent reciprocating motion, which not only seriously restricts production efficiency, but also has a series of technical problems such as high noise, low precision, and poor reliability.

[0033] In order to automatically, accurately and conveniently complete the double steel bar welding work and improve the work efficiency and reliability of double steel bar welding, the present application provides an embodiment of a fully automatic double steel bar flat welding machine, see Figure 1 In this embodiment, the fully automatic double steel bar flat welding machine specifically comprises: a transmission device fixed on the chassis body, an automatic welding mechanism 100 ( Figure 1 The automatic feeding mechanism 200 (shown as “mechanism 1”) and the automatic feeding mechanism 200 ( Figure 1 “Institution 2” is shown in the figure).

[0034] The transmission device is used to drive multiple longitudinal reinforcements 104 to move horizontally at a constant speed in the same feeding direction under the drive of the motor 19. The automatic feeding mechanism 200 is used to move the transverse reinforcement 103 between the two longitudinal reinforcements 104 under the drive of the transmission device. The automatic welding mechanism 100 is used to weld the connection between the longitudinal reinforcement 104 and the transverse reinforcement 103 under the drive of the transmission device. The transmission device is also used to drive the double steel bars 2 obtained after welding to continue to move in the feeding direction.

[0035] It is understandable that the steel bar structure consisting of two parallel cold-drawn steel wires (i.e. the longitudinal bars 104 described in the present application) with welded transverse wires (i.e. the transverse bars 103 described in the present application) arranged between them can be called "double steel bars 2".

[0036] Optionally, the transmission device of the present application can drive multiple longitudinal reinforcements 104 to move at one time. Preferably, it can drive two parallel longitudinal reinforcements 104 to move at one time. The present application does not specifically limit the number of longitudinal reinforcements 104 during welding, and at least two are sufficient.

[0037] Optionally, the transmission device is provided with a motor 19, such as a stepper motor. At the same time, the present application can also set up an existing power supply system to drive the motor 19 to work. The present application does not specifically limit the specific type and specific electrical connection relationship between the power supply system and the motor 19, as long as it can generate driving force.

[0038] See also Figure 1 In a specific example, the transmission device can be composed of a motor 19, a reduction pulley group 18, a clutch 17, a main gear 16, a front roller drive gear 14, a rear roller drive gear 13, an automatic welding structure drive gear 15, a rear roller synchronous pulley group 11, a front roller synchronous pulley group 5, a front active feed roller 4, a front passive feed roller 3, a rear active feed roller 10, a rear passive feed roller 9, a cross-rib loading disc synchronous pulley group 8, two welding wheel main synchronous pulley groups 6, two welding wheel auxiliary synchronous pulley groups 7, a front straightening roller group 1 and a rear straightening roller group 12.

[0039] It can be understood that, under the premise of being able to drive the automatic feeding mechanism 200 and the automatic welding mechanism 100 to move, the transmission device can also be composed of other existing transmission components. The above specific example of the present application is only a specific embodiment that can demonstrate the feasibility of the transmission device, rather than a specific limitation on the specific structure of the transmission device.

[0040] Optionally, the motor 19 of the transmission device can output a continuous and stable driving force so that the longitudinal ribs 104 can move at a constant speed, which is obviously different from the intermittent reciprocating motion in the prior art, thereby ensuring the accuracy and reliability of the welding work.

[0041] From the above description, it can be seen that according to the fully automatic double steel bar flat welding machine provided by the embodiment of the present application, a transmission device fixed on the chassis body, an automatic welding mechanism 100 and an automatic feeding mechanism 200 respectively connected to the transmission device are arranged; first, the transmission device drives multiple longitudinal bars 104 to move horizontally at a uniform speed in the same feeding direction under the drive of the motor 19, and then the automatic feeding mechanism 200 moves the transverse bar 103 to between the two longitudinal bars 104 under the drive of the transmission device, and then the automatic welding mechanism 100 is driven by the transmission device to weld the connection between the longitudinal bar 104 and the transverse bar 103, and at the same time, the transmission device is also used to drive the double steel bar 2 obtained after welding to continue to move in the feeding direction, which is different from the series of problems of low production efficiency, high noise, low precision and poor reliability caused by intermittent reciprocating motion in the prior art. In the present application, the longitudinal bar 104 always maintains uniform linear motion during the welding process, so the present application can automatically, accurately and conveniently complete the double steel bar welding work, thereby improving the work efficiency and reliability of double steel bar welding.

[0042] See also Figure 2As a preferred embodiment, the automatic welding mechanism 100 includes a right welding disc 101 and a left welding disc 105 respectively arranged on both sides of the longitudinal rib 104, the right welding disc 101 and the left welding disc 105 are connected to the transmission device in transmission connection, and rotate in opposite directions under the drive of the transmission device to drive the longitudinal rib 104 to move in the feeding direction.

[0043] As a preferred embodiment, the automatic welding mechanism 100 further includes at least one welding head 102 respectively arranged on the edges of the right welding wheel disc 101 and the left welding wheel disc 105, and the welding head 102 is used to perform welding work after power is turned on.

[0044] In a specific example, the automatic welding mechanism 100 is composed of a right welding wheel 101, a left welding wheel 105, a transverse reinforcement loading tray 106, and eight welding heads 102. After the longitudinal reinforcement 104 and the transverse reinforcement 103 are welded by the welding heads 102 of the automatic welding mechanism 100, they become double steel bars 2. The welding heads 102 are evenly distributed on the circumference of the wheel. The arc length between the two welding heads 102 can be adjusted by replacing the wheel or the welding head 102 to control the arrangement spacing of the transverse reinforcement 103 of the double steel bars 2; the rotation of the welding head 102 and the welding machine is realized by a slip ring 201 or a brush installed at the fixed shaft end of the wheel.

[0045] Specifically, two parallel longitudinal ribs 104 move in a straight line at a uniform speed in the feeding direction. A right welding disc 101 and a left welding disc 105 are installed on both sides of the longitudinal ribs 104. The two discs are driven by a pair of synchronous pulleys with opposite torsion directions. A number of welding heads 102 are installed on each disc. When the welding heads 102 contact the parallel longitudinal ribs 104, the linear velocities of the contact points of the two are consistent. At the same time, the transverse rib loading tray 106 carries a transverse rib 103 through the electromagnet 203 and is placed between the two longitudinal ribs 104. At this moment, the corresponding two welding heads 102 are energized to weld the transverse rib 103 and the longitudinal rib 104 together.

[0046] It can be understood that, under the premise of being able to drive the longitudinal reinforcement 104 to move and perform welding work, the automatic welding mechanism 100 can also be composed of other existing transmission components and existing welding components. The above specific example of the present application is only a specific embodiment that can demonstrate the feasibility of the automatic welding mechanism 100, rather than a specific limitation on the specific structure of the automatic welding mechanism 100.

[0047] See also Figure 3As a preferred embodiment, the automatic loading mechanism 200 includes a loading box 204 for accommodating transverse ribs 103 and a transverse rib loading tray 106 provided with at least one electromagnet 203, the electromagnet 203 is fixed to the edge of the transverse rib loading tray 106 through an electromagnet fixing plate 205, the transverse rib loading tray 106 is connected to the transmission device in transmission connection, and rotates along the center of a circle under the drive of the transmission device, so as to move the transverse ribs 103 in the loading box 204 through the magnetic attraction of the electromagnet 203.

[0048] In a specific example, the automatic feeding mechanism 200 is composed of a transverse rib 103 , a feeding plate 106 , two electromagnets 203 , two electromagnet fixing plates 205 , a slip ring 201 , a slip ring flange 202 and a feeding box 204 .

[0049] Specifically, the transverse rib loading tray 106 is driven by a synchronous pulley set driven by the third gear, realizing uniform linear motion. A plurality of electromagnets 203 are installed on the transverse rib loading tray 106, and the electromagnet fixing sheet 205 is used to fix it on the transverse rib loading tray 106. The electromagnet 203 is used to absorb the transverse rib 103. One end of the loading tray is fixedly connected to the synchronous pulley, which is hinged to the chassis frame. The other end of the loading tray is hinged to the slip ring flange 202, which is a hollow structure. The slip ring 201 is fixed to the slip ring flange 202 and is fixedly connected to the chassis frame. The rotor end of the slip ring 201 is connected to the electromagnet 203 through the hollow structure of the flange 202 to ensure the rotation of the wire. The loading box 204 is fixed at the far end, and the transverse rib 103 can be orderly delivered to the suction position of the electromagnet through the existing structure, thereby realizing the loading of the transverse rib 103.

[0050] It can be understood that, under the premise of being able to drive the movement of the transverse rib 103, the automatic feeding mechanism 200 can also be composed of other existing transmission components. The above specific example of the present application is only a specific embodiment that can demonstrate the feasibility of the automatic feeding mechanism 200, rather than a specific limitation on the specific structure of the automatic feeding mechanism 200.

[0051] As a preferred embodiment, it also includes a front straightening roller group 1 and a rear straightening roller group 12 arranged on the chassis body, and the longitudinal ribs 104 pass through the front straightening roller group 1 and the rear straightening roller group 12 to determine the feeding direction.

[0052] Optionally, the front straightening roller group 1 and the rear straightening roller group 12 can be existing straightening machine devices. After the front straightening roller group 1 is rolled, a cold drawing device can be set as needed, and the rear straightening roller group 12 can also be omitted as needed.

[0053] As a preferred embodiment, the motor 19 of the transmission device is connected to the main gear 16, and the main gear 16 is transmission-connected to a first sub-gear, and the first sub-gear is used to drive the front active feed roller 4 and the front passive feed roller 3 arranged on both sides of the longitudinal rib 104, so that the front active feed roller 4 and the front passive feed roller 3 drive the longitudinal rib 104 to move.

[0054] As a preferred embodiment, the main gear 16 of the transmission device is also connected to a second sub-gear, and the second sub-gear is used to drive the rear active feed roller 10 and the rear passive feed roller 9 arranged on both sides of the double steel bars 2, so that the rear active feed roller 10 and the rear passive feed roller 9 drive the double steel bars 2 obtained after welding to move.

[0055] As a preferred embodiment, the main gear 16 of the transmission device is also transmission-connected to a third sub-gear, and the third sub-gear is synchronously connected to a first set of synchronous pulleys 6 and a second set of synchronous pulleys 8. The first set of synchronous pulleys 6 is used to drive the automatic welding mechanism 100 to rotate, and the second set of synchronous pulleys 8 is used to drive the automatic feeding mechanism 200 to rotate.

[0056] As a preferred implementation manner, the first sub-gear, the second sub-gear and the third sub-gear rotate synchronously.

[0057] Optionally, the cross-rib loading plate 106 and the left and right welding wheels of the automatic welding mechanism 100 are driven by the same gear in the transmission device and are driven separately by a synchronous belt with a set speed ratio to ensure the synchronization of the rotation of the two. The ratio of the circumferential arc length between two adjacent welding heads to the circumferential arc length of two adjacent electromagnets is inversely proportional to the speed ratio of the wheels, ensuring the synchronization of loading and welding.

[0058] In a specific example, the motor 19 of the transmission device is fixed on the chassis frame, the output shaft of the motor 19 of the transmission device is fixedly connected to the reduction pulley group 18 through a coupling, and the clutch 17 is driven by the reduction pulley group 18. The other end of the clutch 17 is connected to the main gear 16 through the main shaft, and three sub-gears are matched with the main gear 16. The first sub-gear drives the front active feed roller 4 through the synchronous pulley, and cooperates with the front passive feed roller 3 to drive the two unwelded parallel longitudinal steel bars to achieve uniform linear motion; the second sub-gear drives the rear active feed roller 10 through the synchronous pulley , cooperates with the rear passive feed roller 9 to drive the welded double steel bars 2 to maintain uniform linear motion; the third sub-gear is fixedly connected to the two sets of synchronous pulleys at the same time, wherein the first set of synchronous pulleys 6 is used to drive two welding wheel sub-synchronous pulley groups 7, and the two welding wheel sub-synchronous pulley groups 7 adopt 90-degree twisting synchronous belt drive technology, and the twisting directions are opposite to each other, thereby driving the right welding wheel 101 and the left welding wheel 105 in opposite directions to achieve uniform rotation in opposite directions, and the second set of synchronous pulleys 8 is used to drive the transverse reinforcement loading tray 106 in the automatic welding mechanism 100 to rotate.

[0059] At the same time, since the rotation of the right welding wheel 101, the left welding wheel 105 and the cross-rib loading plate 106 are all output by the secondary gear and transmitted by the synchronous belt, the rotation of the three can be guaranteed to have good synchronization, thereby ensuring the welding quality. The front straightening roller group 1 and the rear straightening roller group 12 are driven by separate adjustable speed motors 19 to cooperate to achieve the straightening function.

[0060] See also Figure 4 As a preferred embodiment, it also includes a PLC controller arranged in the chassis body, and the PLC controller is electrically connected to the motor 19 of the transmission device, the welding head 102 of the automatic welding mechanism 100, and the front straightening roller group 1 and the rear straightening roller group 12.

[0061] Specifically, a PLC controller can be set up as the control unit of the fully automatic double steel bar 2 flat welding machine of the present application. Specifically, the PLC controller can be connected to the motor drive module to control the operation of the motor 19 through the motor drive module; the PLC controller can also be connected to the electromagnetic clutch 17 to control the operation of the clutch 17; the PLC controller can also be electrically connected to the electromagnet 203 to control the magnetic attraction of the electromagnet 203. Specifically, the rotational switching of the electromagnet 203 and the PLC controller can be achieved through a slip ring 202 or a brush installed on the fixed shaft end of the cross-bar loading tray 106; the PLC controller can also be electrically connected to the welding drive to control the operation of the welding head 102; the PLC controller can also be connected to the straightening roller module to drive the steel bar to move; the PLC controller can also be connected to the sensor signal module to receive the induction signals collected by each sensor; the PLC controller can also receive user instructions to perform human-machine interaction such as motor 19 speed regulation and mode selection.

[0062] In a specific example, the workflow of the present application can be that the two longitudinal reinforcements 104 first pass through the straightening rollers and are driven by the front active feed roller 4 and the front passive feed roller 3 to perform uniform linear motion. When passing through mechanism one at a uniform speed, mechanism one welds the transverse reinforcement 103 synchronously transported to the position by mechanism two and the two parallel longitudinal reinforcements 104 together to form double reinforcements 2. Then the double reinforcements 2 pass through the feeding rollers and straightening machine driven by the rear active feed roller 10 and the rear passive feed roller 9 to complete the entire workflow.

[0063] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
