In order to solve the problem of low welding efficiency caused by the complicated steps required for manually switching a single-wire welding mode and a double-wire welding mode in the prior art, an embodiment of the invention provides a single-double-wire switching system for improving the welding efficiency, and the simple structure of the system is shown in fig. 1 and comprises:
the single-wire and double-wire signal switching mechanism 01 is used for receiving a welding mode switching instruction given by a user and sending a switching signal to the welding power supply 02;
the welding power supply 02 determines a welding mode according to the switching signal after receiving the switching signal sent by the single-wire and double-wire signal switching mechanism 01, outputs welding current and welding voltage corresponding to the welding mode to the wire feeder 03, and sends a welding mode instruction to the wire feeder 03;
the wire feeding mechanism 03 is connected with the welding power supply 02 and the welding gun respectively, the wire feeding mechanism 03 receives a welding mode instruction sent by the welding power supply 02, transmits an electrode required by the welding mode to the welding gun 04, and sends a welding mode signal to the welding gun 04;
the welding torch 04 receives the welding mode signal transmitted from the wire feeder 03, and performs welding in the welding mode using the electrode transmitted from the wire feeder 03.
In a specific embodiment, in order to ensure that the welding device can normally work in the application scenarios of gas shielded welding, such as MIG (metal inert gas) welding or MAG (metal active gas) welding, the single-double wire switching system further includes a shielding gas compressed gas cylinder and an air compressed gas cylinder, which are both connected to the welding gun 04 and used for providing shielding gas and air required for welding.
In a specific embodiment, a single-wire and double-wire signal switching mechanism 01 is arranged, a welding mode switching instruction given by a user is received, and a switching signal is sent to a welding power supply 02; after receiving a switching signal sent by the single-wire and double-wire signal switching mechanism 01, the welding power supply 02 determines a welding mode according to the switching signal, outputs a welding current and a welding voltage corresponding to the welding mode to the wire feeder 03, and sends a welding mode instruction to the wire feeder 03; the wire feeding mechanism 03 is respectively connected with the welding power supply 02 and the welding gun 04, receives a welding mode instruction sent by the welding power supply 02, transmits an electrode required by the welding mode to the welding gun 04, and sends a welding mode signal to the welding gun 04; the welding torch 04 is provided to receive a welding mode signal transmitted from the wire feeder 03, and the welding torch performs welding in the welding mode by using the electrode transmitted from the wire feeder 03. By constructing the single-double wire switching system consisting of the single-double wire signal switching mechanism 01, the welding power supply 02, the wire feeding mechanism 03 and the welding gun 04, the automatic switching of the welding mode by using one welding power supply can be realized according to the welding mode switching instruction given by a user, and the complicated steps of manual switching are not needed, so that the welding work efficiency is improved.
In a specific embodiment, the single-wire and dual-wire signal switching mechanism 01 receives a welding mode switching instruction given by a user, and sends a switching signal to the welding power supply 02 to control the welding power supply 02 to set a corresponding welding mode, and in order to reduce cost and simplify the structure, the switching signal can be directly integrated on the welding gun 04, as shown in fig. 2, a switching button is arranged on the welding gun 04, so that an operator can select single-wire welding and dual-wire welding. Or directly integrated into the welding power supply 02, as shown in fig. 3, a switch button is provided on the welding power supply 02 for the operator to select between single wire bonding and dual wire bonding. It can be understood by those skilled in the art that the single-wire and dual-wire signal switching mechanism 01 may be separately disposed, or may be integrally disposed on other signal generating devices, as long as an operator can freely switch the welding mode and transmit a signal to the welding power supply 02, and the present embodiment is not limited thereto. When the single-wire welding is selected by the operator at the single-wire and double-wire signal switching mechanism 01, the single-wire and double-wire switching system enters the single-wire welding mode, and when the single-wire welding is selected by the operator at the single-wire and double-wire signal switching mechanism 01, the single-wire and double-wire switching system enters the double-wire welding mode.
In a particular embodiment, the welding power supply 02 may be any known type of welding power supply 02 capable of delivering current power and receiving a transmitted signal as an output device for providing welding current and voltage. After receiving the switching signal sent by the single-wire and double-wire signal switching mechanism 01, the welding power supply 02 determines a welding mode according to the switching signal, switches to the gear where the software package corresponding to the welding mode is located, and outputs the welding current and the welding voltage corresponding to the welding mode. And to ensure that the wire feeder 03 is engaged with the welding mode, a welding mode command is also sent to the wire feeder 03.
The wire feeder 03 is connected to the welding power supply 02 and the welding torch 04, and basically functions to feed the electrode to the welding torch 04 according to the current and voltage output from the welding power supply 02. In addition, in order to enable automatic switching between single-wire welding and twin-wire welding, as shown in fig. 4 and 5, the wire feeder 03 is provided with two driving devices in the conveying direction of the electrode;
each driving device comprises a pressure control part, a driving part and a driving roller group.
Each driving roller group comprises a first roller and a second roller which are oppositely arranged, and a first channel and a second channel are formed between the first roller and the second roller;
the driving piece is connected with the first roller, and the pressure control piece controls the driving piece to press the first roller onto the second roller or separate the first roller from the second roller; specifically, the pressure control member is connected with the driving member through a control line, and the driving member may be a pressure arm, and the pressure control member determines the welding mode at this time according to a welding mode command sent by the received welding power source 02, and determines whether the pressure arm is to press the first roller against the second roller, or whether the pressure arm is not required to press the first roller, so that the first roller is separated from the second roller.
In the radial direction of the second roller, the depth of the first channel is smaller than that of the second channel, and the first channel of one driving roller group is communicated with the second channel of the other driving roller group to form an electrode conveying channel.
For the sake of understanding, the driving device on the right side of the drawing is referred to as a pressure driving device 1 by taking fig. 4 as an example and includes a first pressure control member which controls the pressure arm 1 through a control line to press the first roll of the first driving roll group against the second roll or to separate it from the second roll. The drive device on the left in the figure is denoted as a pressure drive device 2 and comprises a second pressure control element which controls the pressure arm 2 via a control line to press the first roller of the second set of drive rollers against the second roller or to separate it from the second roller. The driving roller is connected with the first driving roller group and the second driving roller group, and after the motor of the wire feeding mechanism 03 is started, the driving roller can rotate and drive the second rollers in the first driving roller group and the second driving roller group to rotate.
The electrode source 1 can provide a first electrode F1, and the first electrode F1 is placed in a first electrode conveying channel which is formed by communicating a first channel of the first driving roller set and a second channel of the second driving roller set. The electrode source 2 can provide a second electrode F2, the second electrode F2 being placed in a second electrode transport channel which is made up of a second channel of the first set of drive rollers and a first channel of the second set of drive rollers communicating. Since the depth of the first channel is smaller than the depth of the second channel in the radial direction of the second roller, when the pressing arm 1 presses the first roller in the first driving roller group against the second roller, the first electrode F1 placed on the first channel in the first driving roller group is stressed, while the second electrode F2 placed on the second channel in the first driving roller group is not stressed, the first electrode F1 is transferred, while the second electrode F2 is not moved; similarly, when the pressing arm 2 presses the first roller of the second drive roller group against the second roller, the second electrode F2 is transferred while the first electrode F1 is not moved.
Therefore, when double-wire bonding is selected, the first pressure control member and the second pressure control member both control the pressing arms to move toward the drive roller groups simultaneously, so that the first roller in each drive roller group is pressed against the second roller, so that both electrodes are transferred. When single wire bonding is selected, either one of the first and second pressure control members controls movement of the pressure arm toward the drive roller set such that a corresponding one of the electrodes is transferred.
In a specific embodiment, the first channel and the second channel are formed by forming the grooves a and the grooves B having different depths and different widths on the first roller and the second roller, specifically, as shown in fig. 6, the dimension (depth) of the groove dimension R of the groove B is k times (k > 1) the dimension S (depth) of the groove a, and the width of the groove B is also greater than the width of the groove a. The above embodiments only discuss electrodes of the same diameter, but electrodes of different diameters may be used, only the dimensions of the grooves need to be changed.
The welding gun 04 receives the welding mode signal sent by the wire feeder 03, and performs welding in the corresponding welding mode by using one or two electrodes transmitted by the wire feeder 03. In specific implementation, the welding gun 04 and the wire feeder 03 are connected by a liner tube with a matched size, and the liner tube can be a single tube or a double tube. When a single-tube liner tube is used, the diameter of the liner tube is generally 2.5 to 3 times of the diameter of the electrode; when a dual tube liner is used, each tube diameter is typically 1.5 times the electrode diameter.
In a specific embodiment, a single-wire and dual-wire switching system is provided, further comprising: and the gun cleaning and wire cutting mechanism is used for cutting the adhered welding wires and cleaning the welding gun after welding is finished. During specific implementation, the gun cleaning and wire cutting mechanism is specifically used for: after the welding gun is monitored to be placed, namely when welding is finished, the welding gun is cut off and cleaned to ensure that the welding wires are not adhered, so that the two welding wires are kept independent after welding, and subsequent effective welding can be ensured. In particular, when the single-wire welding mode is changed to the double-wire welding mode, because two welding wires during the single-wire welding are very easy to adhere, and when the double-wire welding is performed, the two welding wires need to be kept independent, in a specific embodiment, the gun cleaning and wire cutting mechanism is specifically used for: when the single-wire and double-wire signal switching mechanism receives a command for switching the single-wire welding mode to the double-wire welding mode, the adhered welding wires are cut off, and a welding gun is cleaned, so that the welding can be normally carried out after the welding mode is switched. At the moment, the gun cleaning and wire cutting mechanism is connected with the single-double wire signal switching mechanism 01. As shown in fig. 7, which is a flowchart of a work flow of the embodiment that single-wire welding and double-wire welding conversion is required, after single-wire welding is finished, if the single-wire welding is required to be converted into double-wire welding, a welding gun is cleaned and cut, a welding power supply 02 calls a double-wire welding software package, and two pressing arms of a wire feeding mechanism 03 are both pressed to perform double-wire welding.
In order to obtain a better welding effect during the twin-wire welding, the single-twin-wire switching system further comprises a welding contact device, and the welding contact device is connected with the welding gun 04 and used for gathering the electrodes so as to obtain a better welding effect.
Specifically, as shown in fig. 8, the welding contact device includes:
a welded joint 801 having two through holes running therethrough;
a guide assembly 802, one end of which is connected with the welding joint and which has two welding wire channels running through it, each welding wire channel being communicated with a through hole, the welding wire channels forming an outlet at the other end of the guide assembly;
each welding wire channel is provided with a guide section, the guide sections gather towards the outlet in the direction from one end of the guide assembly to the other end of the guide assembly, and the guide sections are used for gathering the electrodes towards the outlet.
In particular, the guide member needs to have a proper size, as shown in fig. 8, the diameter of each through hole of the welding joint is N, N is generally 1.5 to 2 times the diameter of the electrode, the size of the end of the guide member connected to the welding joint is L, L is generally 2.5 to 3.5 times the diameter of N, the size of the outlet of the guide member is M, and M is generally 1.5 to 2.5 times the diameter of N.
In a specific embodiment, the single-wire and double-wire switching system further includes: the electrode clamping device is used for clamping or releasing an electrode in the welding gun 04 so as to avoid welding errors caused by the fact that another welding wire is driven during single wire welding. In a specific embodiment, the electrode clamping device is connected with a first pressure control member in the first driving device and is used for clamping or releasing the second electrode according to an electrode control command transmitted by the first pressure control member. When only the first pressure control piece receives a welding mode instruction sent by the welding power supply 02, the welding mode at the moment is determined to be single wire welding, the pressure arm is determined to be controlled to operate, so that the first electrode is transmitted to the welding gun 04, meanwhile, the first pressure control piece can send an electrode control instruction to the electrode clamping device, the electrode clamping device is controlled to clamp a second electrode in the welding gun 04, and the second electrode is prevented from being driven by the first electrode. When the first pressure control piece and the second pressure control piece both receive a welding mode instruction sent by the welding power supply 02, the welding mode at the moment is determined to be double-wire welding, the pressure arm needs to be controlled to operate to transmit the first electrode and the second electrode to the welding gun 04, meanwhile, the first pressure control piece sends an electrode control instruction to the electrode clamping device, and the control electrode releases the second electrode in the welding gun 04 to ensure that the second electrode and the first electrode can be normally used.
Similarly, the electrode clamping device may be connected to the second pressure control element in the second driving device, and configured to clamp or release the first electrode according to the electrode control command transmitted by the second pressure control element, so as to control the first electrode, and avoid being driven by the second electrode when the second electrode is used for single wire bonding.
To specifically illustrate the single-double wire switching system provided in this embodiment, an embodiment is provided, which is shown in fig. 1 and includes: the welding device comprises a welding power supply, a wire feeding mechanism, a double-wire welding gun, a single-double-wire signal switching mechanism (integrated in the double-wire welding gun and not marked on the figure), a protective gas compressed gas cylinder and an air compressed gas cylinder. The welding contact device is arranged on the twin-wire welding gun, and a side wall of the welding contact device is provided with a hole, so that the electrode clamping device can control one electrode in the welding contact device, for example, as shown in fig. 9, the electrode clamping device controls an electrode F2, and is connected with the first pressure control part, and the electrode clamping device can be any controllable execution element such as an air cylinder or a hydraulic cylinder.
The flow of the single-wire and double-wire switching system for realizing the fast switching between the single-wire welding and the double-wire welding is shown in fig. 10, and includes:
before an operator performs welding, whether single-wire welding or double-wire welding is performed is selected through a button on a double-wire welding gun, if single-wire welding is selected, a single-wire welding instruction is sent to a welding power supply 02 by the welding gun, after the welding power supply 02 receives the instruction, the gear of a single-wire welding software package is switched, meanwhile, a single-wire signal is sent to a double-wire feeding mechanism 03 by the welding gun, at the moment, a first pressure control piece works, a second pressure control piece is in standby, so that a pressure arm 1 corresponding to the first pressure control piece is pressed, a pressure arm 2 corresponding to the second pressure control piece is opened, an electrode F2 is clamped by an electrode clamping device, when a motor works, a driving roller 1 drives a first driving roller to move and a second driving roller to move, only an electrode F1 is subjected to wire feeding force to perform electrode transmission, and at the moment, the single-wire welding of the electrode F1 can be used for welding.
Similarly, if the operator selects the twin-wire welding mode, the twin-wire welding gun sends a twin-wire welding command to the welding power supply 02, the welding power supply 02 is switched to the gear of the twin-wire welding software package, and after the twin-wire feeding mechanism 03 receives the twin-wire welding command, the first pressure control part works at the moment, the second pressure control part also works, so that the pressure arm 1 corresponding to the first pressure control part and the pressure arm 2 corresponding to the second pressure control part are all pressed, the electrode clamping device is released at the moment, and the electrode F1 and the electrode F2 can be used for welding together.
By utilizing the single-wire and double-wire switching system provided by the specific example, one-button switching between single-wire welding and double-wire welding is realized.
Based on the same inventive concept, an embodiment of the present invention further provides a working method of a single/dual wire switching system, where the principle of the problem to be solved is similar to that of the single/dual wire switching system, and repeated parts are not repeated again, and the working method is implemented by using the single/dual wire switching system, as shown in fig. 11, including:
step 1101: the single-wire and double-wire signal switching mechanism 01 receives a welding mode switching instruction given by a user and sends a switching signal to the welding power supply 02;
step 1102: after receiving the switching signal, the welding power supply 02 determines a welding mode according to the switching signal, outputs a welding current and a welding voltage corresponding to the welding mode to the wire feeder 03, and sends a welding mode instruction to the wire feeder 03;
step 1103: the wire feeder 03 receives a welding mode instruction, transmits electrodes required by a welding mode to the welding gun 04, and sends a welding mode signal to the welding gun 04; wherein, the wire feeder 03 is respectively connected with the welding power supply 02 and the welding gun 04;
