Description

Technical Field

[0001] The invention belongs to the technical field of wire material processing or treatment, and in particular relates to a composite stirrup welding device. Background Art

[0002] Composite stirrups often refer to a structural form in which a number of longitudinal or\ and transverse steel bars are added inside the square stirrups (hoops); the stirrups can be prefabricated and then directly connected to the main reinforcement of the component through binding or welding during the construction process to shorten the construction period.

[0003] At present, for the prefabrication of ordinary hoop, it can be manually bent and then welded, and there are also many automatic hoop bending equipment that can meet the needs of prefabricated hoop, such as: CN108057821A, CN207464065U, CN207431146U; however, if the construction requires a composite hoop with steel bars connected inside the hoop, the steel bars inside the hoop are basically assembled and welded by hand, that is, the prefabricated hoop and the steel bars to be added to the hoop are manually placed or connected according to the designed position, and then welded to make the composite hoop. Such a manufacturing process is inefficient, and it is still necessary to consider realizing automated production as much as possible through mechanical equipment to improve efficiency and quality. Automated mechanical equipment usually includes several required feeding units, discharging units, and welding bodies, and the structural design needs to be implemented one by one. The original designed equipment can realize the automatic welding of composite hoop with parallel and spaced transverse bars inside.

[0039] The specific implementation modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] See also Figure 1 , Figure 2A composite stirrup welding device according to a specific embodiment includes a stirrup feeding unit 1000, a first welding unit 2000, a transfer unit 4000, a second welding unit 5000 and a discharge unit 6000 which are arranged in sequence to form an assembly line. The first welding unit 2000 and the second welding unit 4000 have the same structure and also include two welding cross reinforcement feeding units 3000 which are arranged in a one-to-one correspondence with the first welding unit 2000 and the second welding unit 4000.

[0041] See also Figure 3-6 The stirrup feeding unit 1000 includes a base frame 1001, on which a group of rotatable rollers 1002 are horizontally arranged so as to feed stirrups (not shown in the figure) placed thereon during rotation. A limiting unit is provided at one end of the base frame 1001 so as to allow the stirrups to be fed out according to design requirements. The limiting unit includes two oppositely arranged limiting plates 1003, which are located above the rollers 1002 and are perpendicular to the rollers 1002 so as to act on the stirrups through their opposite inner sides. A lever-type precise limiting mechanism is provided at the feeding end of the limiting plate 1003, and the lever-type precise limiting mechanism includes a lever action plate 1009, which is rotatably connected to the outer side of the limiting plate 1003 with its middle as a turning point, and one end of the lever action plate 1009 is a driving end 1091. An elastic element 1095 is compressed between the driving end 1091 and the outer side surface of the limit plate 1003 to provide a force to the other end. The other end of the lever action plate 1009 is an action end 1092. The action end 1092 is provided with a positioning portion 1093 which can maintain contact with the outer side surface of the limit plate 1003 under the force provided by the driving end 1091. The free end of the action end 1092 extends out of the delivery end of the limit plate 1003 and has an action surface 1094. The action surface 1094 protrudes from the inner side surface of the limit plate 1003 to act on the stirrups to achieve precise limiting. The limit plate 1003 is provided with a vertical sliding block 1008 which can slide vertically. The lower surface of the vertical sliding block 1008 at least partially protrudes from the inner side surface of the limit plate 1003 so as to act on the stirrups from top to bottom during vertical sliding.

[0042] The stirrup feeding unit 1000 roughly limits the position where the stirrup is sent out through the inner side surfaces of the two limit plates 1003, but the spacing between the two limit plates 1003 cannot be equal to or less than the size of the stirrup, otherwise the stirrup will be stuck and the feeding will be affected. The use of the lever-type precise limiting mechanism makes the sending end position of the two limit plates 1003 have two action surfaces 1094 protruding from their inner side surfaces respectively. When implemented, the spacing between the two action surfaces 1094 is less than or equal to the size of the stirrup, which can compensate for the inner side surfaces of the two limit plates 1003. The gap between the two action surfaces 1094 and the stirrups can achieve the effect of precise limiting, so that the stirrups can be accurately sent out according to the designed position, and the action surface 1094 is a flexible contact surface provided by one end of the lever action plate 1009. Even if the distance between the two action surfaces 1094 is smaller than the size of the stirrups, when the stirrups pass through, the elastic element 1095 can be compressed by the lever movement to achieve the effect of effectively giving way and maintaining the limiting force. While ensuring the effective limitation of the precise sending position, the stirrups will not be stuck, ensuring the effect of sending in and out. The inner side surfaces of the two limiting plates 1003 act on the stirrups from the left and right directions, and the part of the lower surface of the vertical slider 1008 protruding from the inner side surface of the limiting plate 1003 can act on the stirrups from top to bottom, thereby achieving the effect of limiting the stirrups from all sides, so as to better ensure the feeding position and posture, thereby facilitating the connection with the welding machine unit 2000. The vertical slider 1008 slides up and down because the limit plate 1003 has been rigidly limited from the left and right directions. If the vertical slider 1008 is also rigidly limited in the height direction, the lower surface of the vertical slider 1008 is too low, that is, the distance from the roller 1002 is close, and the stirrups may not be sent between the two limit plates 1003 and below the vertical slider 1008. Therefore, when in use, the vertical slider 1008 is first located at the high point of the vertical sliding, and the stirrups are first sent between the two limit plates 1003, and then the vertical slider 1008 slides vertically downward to act on the stirrups from top to bottom, maintaining the sending posture without affecting the sending of the stirrups. During implementation, the spacing between the two limit plates 1003 is adjustable to improve applicability, and the movement of the two limit plates 1003 can be electrically controlled, and the sending position of the stirrups sent in can be limited by the movement of the limit plates 1003.

[0043] Among them, a connecting lug is provided on the outer surface of the limit plate 1003, and the middle part of the lever action plate 1009 is connected to the connecting lug through a vertical rotating shaft 1096; the positioning part 1093 is a boss provided on the side opposite to the outer side surface of the action end 1092 and the limit plate 1003.

[0044] In this way, the connection structure is simple, the action and positioning are reliable, and the use effect is guaranteed.

[0045] Among them, the free end of the action end 1092 extends out of the delivery end of the limit plate 1003 and continues to extend to the inner side of the limit plate 1003 to be provided with two horizontal side wings 1097, and the two horizontal side wings 1097 are arranged horizontally opposite to each other up and down, and a vertical precision roller 1098 is rotatably connected between the two horizontal side wings 1097, and the outer circumferential surface of the precision roller 1098 forms the action surface 1094.

[0046] In this way, the contact during precise limitation is changed from the sliding friction between the stirrups and the original action surface 1094 to the rolling friction with the precision roller 1098, which is more beneficial to the feeding process and will not scratch the stirrups.

[0047] The limiting plate 1003 is in the shape of a long strip, and an upper convex edge 1031 protruding inward is provided on its upper edge, and a plurality of rotatable vertical rollers 1004 are connected through the upper convex edge 1031. All vertical rollers 1004 are vertical and the upper ends are rotatably connected to the upper convex edge 1031. All vertical rollers 1004 are arranged at intervals along the limiting plate 1003. The vertical rollers 1004 are located between two adjacent rollers 1002 so that the vertical rollers 1004 and the rollers 1002 are arranged alternately. The lower edge of the limiting plate 1003 is provided with a downward extension portion 1032 corresponding to the vertical rollers 1004 one by one, and the extension portion 1032 is also located between the adjacent rollers 1002. An inwardly protruding lower convex edge 1033 is provided between the two rollers 1002 and at the lower edge of the extension portion 1032, and the upper surface of the lower convex edge 1033 is lower than the highest point of the outer circumference of the roller 1002 (i.e., the plane for feeding the stirrups), and the lower end of the vertical roller 1004 is rotatably connected to the corresponding lower convex edge 1033 so that the stirrups can be acted on by the vertical roller 1004 and the stability of the vertical roller 1004 can be ensured; in the direction toward the inner side of the limit plate 1003, the outer circumference of the precision roller 1098 protrudes from the outer circumference of the vertical roller 1004, that is, the highest point of the outer circumference of the precision roller 1098 is higher than the highest point of the outer circumference of the vertical roller 1004.

[0048] In this way, the spacing between the rollers 1002 is cleverly utilized, and the lower end of the vertical roller 1004 is connected to the convex edge of the extension portion 1032 extending downward from the limiting plate 1003. While ensuring that the vertical roller 1004 can effectively contact and act on the stirrups, the connection stability of the vertical roller 1004 is effectively improved, which can greatly extend the service life and always ensure the use effect.

[0049] Among them, the lower surface of the vertical slider 1008 is protruded with two vertical side wings 1081, and the two vertical side wings 1081 are opposite to and parallel to the limit plate 1003. A horizontal roller 1082 is rotatably connected between the two vertical side wings 1081. In the direction away from the limit plate 1003, the corresponding side surface of the vertical side wing 1081 close to the limit plate 1003 is lower than the highest point of the outer circumference of the vertical roller 1004 (that is, the plane acting on the stirrups) so that the stirrups can be acted on by the horizontal roller 1082.

[0050] In this way, the vertical restriction is changed from the sliding friction between the lower surface of the vertical slider 1008 and the passing stirrup to rolling friction with the horizontal roller 1082, which is more favorable for the feeding process and will not scratch the fed objects. In this embodiment, two horizontal rollers 1082 are arranged between the two vertical side wings 1081 of a vertical slider 1008. The two horizontal rollers 1082 are of equal height and are arranged at intervals along the feeding direction to improve the effect of the horizontal rollers 1082.

[0051] The upper convex edge 1031 is provided with a clearance opening 1311 , and the vertical slider 1008 can vertically slide through the clearance opening 1311 . The vertical slider 1008 is located between two adjacent vertical rollers 1004 .

[0052] In this way, the clearance opening 1311 can be used as an auxiliary guide rail for the vertical sliding of the vertical slider 1008, which is beneficial to improving the structural strength; more importantly, the surface of the vertical slider 1008 facing the limit plate 1003 is closer to the limit plate 1003, and the inner wing plate can naturally extend downward and ensure that it is lower than the highest point of the outer circumference of the vertical roller 1004 without extending inward, which is simpler in structure.

[0053] Among them, the vertical slider 1008 is connected to the telescopic cylinder 1083 to drive its vertical movement through the telescopic cylinder 1083, the telescopic cylinder 1083 is fixedly connected to the outer side surface of the limit plate 1003 and its telescopic rod is upward, and the upper surface of the vertical slider 1008 is provided with a bent extension portion 1084 facing the outer side surface of the limit plate 1003 and is connected to the telescopic rod through the bent extension portion 1084, and the bent extension portion 1084 is higher than the upper surface of the limit plate 1003.

[0054] In this way, a feasible drive connection method is provided, which has simple connection and reliable force transmission.

[0055] Wherein, at least one vertical sliding block 1008 is respectively provided at two ends of the limiting plate 1003 .

[0056] In this way, the limiting effect on the posture of the stirrups can be improved. In theory, a vertical slider 1008 can be set between adjacent vertical rollers 1004; when there is only one vertical slider 1008 on a limit plate 1003, it is preferably set at the delivery end of the limit plate 1003; in this embodiment, two vertical sliders 1008 (including corresponding telescopic cylinders 1083) are set on a limit plate 1003, and they are preferably respectively set at the two ends of the limit plate 1003 to ensure the limiting effect on the posture of the stirrups.

[0057] The two limit plates 1003 are further extended toward one end of the incoming material to form a guide plate 1005 , and the distance between the two guide plates 1005 is gradually enlarged to ensure the guiding effect and increase the guiding action range.

[0058] In this way, the guide plate 1005 can always play a role in expanding the range of incoming materials that can be received, making it easier to place the incoming materials and having lower requirements for the placement of the incoming materials.

[0059] The two limit plates 1003 are connected to an adjustment mechanism and the distance between the two limit plates 1003 can be adjusted by the adjustment mechanism.

[0060] In this way, the applicability is improved and it can be used to feed in and limit the feeding out of square stirrups of more specifications.

[0061] Among them, the adjustment mechanism includes a bottom plate 1006 and two drag plates 1007 located below the roller 1002, the bottom plate 1006 is fixedly connected to the base frame 1001, two slide rails 1061 are arranged on the bottom plate 1006 in parallel and at intervals, the lower surface of the drag plate 1007 is provided with two slide grooves 1071 corresponding to the two slide rails 1061 and can be slidably mounted on the two slide rails 1061 of the bottom plate 1006 through the two slide grooves 1071; the drag plate 1007 corresponds to the limit plate 1003 one by one, and the upper surface of the drag plate 1007 is provided with a vertical plate 1072, the vertical plate 1072 passes upward from between the two adjacent rollers 1002 and is connected to the limit plate 1003 so as to drive the limit plate 1003 to move, thereby adjusting the distance between the two limit plates 1003. The bottom plate 1006 is also provided with a screw 1062 parallel to the slide rail 1061 and the screw 1062 is located between the two slide rails 1061. The screw 1062 is composed of two external thread segments with opposite rotation directions. The two carriages 1007 are connected to the screw 1062 through connecting nuts 1073 corresponding to the two external thread segments with opposite rotation directions, respectively. The connecting nuts 1073 are protrudingly connected to the lower surface of the carriage 1007. The two ends of the screw 1062 are respectively It is rotatably connected to the screw seat 1063, and the screw seat 1063 is fixedly connected to the base plate 1006. A driving motor 1064 is connected to either end of the screw 1062. During implementation, a servo motor is used, which is fixedly connected to the outer side of the corresponding screw seat 1063, and its driving shaft is connected to the screw 1062 or connected through a coupling. The servo motor is connected to a PLC controller (not shown in the figure) so as to automatically adjust the distance between the two limit plates 1003 in combination with the input data, which is more convenient to use.

[0062] In this way, the adjustment mechanism is arranged by further utilizing the gap of the roller 1002, and the entire driving and motion structure is located below the roller 1002, which has a clear and concise appearance and reduces safety risks. The screw 1062 is driven to rotate by the driving motor 1064, and the two limit plates 1003 are driven to approach or move away at the same time, so that the middle positions of stirrups of different widths are fixed and the same when they are sent out, which is convenient for connection with the welding machine unit 2000.

[0063] There are a plurality of vertical plates 1072 on the drag plate 1007 and they are spaced apart along the limiting plate 1003 . The upper ends of the vertical plates 1072 are connected to the outer side surfaces of the limiting plate 1003 by bolts.

[0064] In this way, the connection reliability is improved, the connection is more convenient, and the driving performance is good. In this embodiment, three vertical plates 1072 are arranged at intervals on a drag plate 1007 and are connected to the corresponding limit plates 1003.

[0065] The elastic element 1095 is a helical compression spring, both ends of which fall into corresponding sinks on the outer surfaces of the driving end 1091 and the limiting plate 1003 .

[0066] In this way, the installation is reliable, the force provided is stable, and the use effect is guaranteed.

[0067] In this embodiment, an extension arm 1034 is extended from the delivery end of the limiting plate 1003 and the free end of the extension arm 1034 serves as the delivery end of the limiting plate 1003 . The lever-type precise limiting mechanism is arranged at the free end of the extension arm 1034 . During use, the stirrup feeding unit 1000 is followed by the welding machine unit 2000, which horizontally receives and pulls out the stirrups for welding. If the lever-type precise limiting mechanism is close to the last roller 1002, it is not convenient to connect with the welding machine unit 2000, and the lever-type precise limiting mechanism is far away from the subsequent welding position, which is not conducive to maintaining the precise limiting position, that is, in the process of the welding machine unit 2000 pulling the stirrups out to the welding position, the stirrups may shift again and affect the accuracy of the welding position. Therefore, the extension arm 1034 is used to lengthen the delivery end of the limit plate 1003. The structure of the extension arm 1034 is the same as the cross-section of the position where the lower convex edge 1033 is provided on the limit plate 1003, and the vertical rollers 1004 are also arranged at intervals. The lever action plate 1009 is connected to the connecting lug on the outer side of the extension arm 1034 through the rotating shaft 1096, and the use effect of the precise limitation remains unchanged. After increasing the distance between the lever-type precise limiting mechanism and the last roller 1002, the lever-type precise limiting mechanism can be closer to the subsequent welding position, and even during welding, the rear part of the stirrup is still under the restriction of the lever-type precise limiting mechanism, which can better ensure the posture of the stirrup during welding.

[0068] During manufacturing, the limit plate 1003 and the extension arm 1034 can be cut into rectangular plates and welded (the limit plate 1003 and the extension arm 1034 can also be an integral structure), and fixed convex edges are welded on the upper and lower edges respectively, and then the yielding parts corresponding to each roller 1002 are processed by material removal machining, and the correspondingly spaced "extension parts 1032" and "lower convex edges 1033" are formed, and then the yielding openings 1311 are processed. This manufacturing method is relatively simple and has better consistency. Then, a thin-walled guide plate 1005 is welded at an angle at the corresponding end, and a connecting lug is welded at the other end to process the sinking platform into which the spiral compression spring falls. The yielding part of this embodiment is an arc-shaped yielding part with a diameter larger than the roller 1002. During implementation, it can also be a rectangular yielding part without limitation.

[0069] In this embodiment, Figure 3At the middle right position, the motor connected to the base frame 1001 is a driving motor 1064 for driving each roller 1002. A toothed synchronous belt (not shown) can be used to drive and connect with each roller 1002. This is prior art and will not be described in detail.

[0070] In this embodiment, an in-place sensor 1101 and a positioning mechanism are also provided at the delivery end of the base frame 1001. The positioning mechanism includes a vertical telescopic positioning rod 1100 that can be vertically moved, which is driven by a cylinder fixed to the base frame 1001. The telescopic positioning rod 1100 is located outside the roller 1002 and in the middle of the two limit plates 1003 (that is, the distance between the telescopic positioning rod 1100 and the two limit plates 1003 is equal). The in-place sensor 1101 is provided between the telescopic positioning rod 1100 and Between the last roller 1002 at the delivery end, the in-position sensor 1101 is connected to a PLC controller (not shown in the figure), the PLC controller is connected to the drive motor 1064, and is also connected to the drive cylinders of the telescopic cylinder 1083 and the telescopic positioning rod 1100 through corresponding air pressure regulating valves. The telescopic cylinder 1083 can be controlled according to the feeding position information of the stirrup detected by the in-position sensor 1101, thereby controlling the timing of the vertical slider 1008 to act on the stirrup from top to bottom. The sensor can be in the form of mechanical triggering, or a displacement sensor in the form of laser irradiation induction can be selected, without limitation.

[0071] For ease of understanding, the movement process of the stirrup feeding unit 1000 is further introduced. The PLC controller controls the cylinder to drive the telescopic positioning rod 1100 to extend, and its upper end is higher than the highest point of the roller 1002 to block and position the stirrups being fed in. The PLC controller controls the drive motor 1064 to adjust the distance between the two limit plates 1003 to the required distance size. The PLC controller controls the telescopic cylinder 1083 to lift the vertical slider 1008 to the highest point to complete the preparation work. The stirrups are placed on the roller 1002, fed in and introduced into the vertical rollers 1004 of the two limit plates 1003 through the guide plate 1005 to be restricted, and are fed in beyond the last roller 1002 and triggered into place. Sensor 1101, the PLC controller controls the telescopic cylinder 1083 to lower the vertical slider 1008, and limits the stirrups through the horizontal rollers 1082. After the stirrups touch the telescopic positioning rod 1100, they are forced to stop (the drum 1002 can continue to rotate), and are in a state of being restricted on all sides to ensure the posture; after the subsequent process welding machine unit 2000 comes to horizontally undertake and grasp the stirrups, the PLC controller controls the cylinder to drive the telescopic positioning rod 1100 to descend, and its upper end is lower than the drum 1002 and no longer blocks the stirrups. The welding machine unit 2000 pulls out the stirrups horizontally and then welds them. During the process, the stirrups pass through the subsequent vertical rollers 1004 and the precision rollers 1098, so that the delivery position is more accurate.

[0072] See also Figure 7 , Fig. 9The welding machine unit 2000 includes two butt welding machines 2001, and the butt welding machine 2001 includes a main body 2011, and a welding chuck is protruded on one side of the main body 2011, and the welding chuck includes an upper connecting frame 2012 and a lower connecting frame 2015 arranged vertically at intervals, and an upper chuck 2014 is arranged on the upper connecting frame 2012, and a lower chuck 2016 is arranged on the lower connecting frame 2015, and the upper chuck 2014 and the lower chuck 2016 are opposite to each other. Specifically, a clamping cylinder 2013 is arranged on the upper connecting frame 2012, and a telescopic rod of the clamping cylinder 2013 extends downward and connects the upper chuck 2014 so as to move up and down to cooperate with the lower chuck 2016 below to complete the butt welding. These belong to the existing structure and are not repeated here; the welding chucks of the two butt welding machines 2001 are relatively arranged to In order to weld both sides of the stirrup at the same time, the two butt welding machines 2001 can be slidably mounted on two parallel horizontal guide rails 2003 so as to slide toward or away from each other to adjust the spacing so as to be suitable for processing stirrups of different widths; a feeding mechanism 2002 is provided on the lower connecting frame 2015 of the butt welding machine 2001; the feeding mechanism 2002 includes a longitudinal guide rail 2022 and a clamping unit 2023 slidably arranged on the longitudinal guide rail 2022, the longitudinal guide rail 2022 is perpendicular to the horizontal guide rail 2003 and fixedly connected to the free end of the lower connecting frame 2015, the two clamping units 2023 are located between the two lower clamps 2016 so as to clamp the transverse reinforcement of the stirrup and realize the actions of sliding feeding, sliding stop for coordinated welding and sliding discharging in sequence in combination with the sliding on the longitudinal guide rail 2022.

[0073] The two pairs of welding machines 2001 of the welding machine unit 2000 can weld both sides of the stirrups at the same time and the distance between the two pairs of welding machines 2001 is adjustable, which can be used to weld transverse reinforcements on stirrups of different widths. The length direction of the longitudinal guide rail 2022 is used as the feeding path direction during stirrup processing, and the stirrups are fed under the clamping of the clamping unit 2023. The two clamping units 2023 are located between the two lower clamps 2016 and the two limit plates 1003 to clamp the stirrups blocked and positioned by the telescopic positioning rod 1100, that is, parallel to one side of the transverse guide rail 2003, and fed horizontally. The longitudinal reinforcements on both sides of the stirrups correspond to the two lower clamps 2016 and are placed on the two lower clamps 2016 as they are fed. The feeding is stopped according to the designed welding position, and the welding transverse reinforcement feeding unit 3000 is placed on the transverse reinforcements of the same length as the stirrups. When welding the transverse reinforcement, the two upper clamps 2014 fall down, and the two ends of the welded transverse reinforcement are welded and connected with the longitudinal reinforcements on both sides of the stirrups. The upper clamp 2014 moves upward, and the two clamping units 2023 continue to feed. The designed welding stop positions can be several intervals. The welding process is the same as above. After the welding of the last welded transverse reinforcement is completed, the upper clamp 2014 and the lower clamp 2016 are kept clamped on the stirrups (the power-on welding time is set as needed, and it is not necessary to keep the power on all the time). The two clamping units 2023 release the clamping of the front transverse reinforcement of the stirrups, slide forward and clamp the rear transverse reinforcement of the stirrups, and the upper clamp 2014 moves upward to reset, release the stirrups, and the two clamping units 2023 clamp the stirrups and continue to feed them to the tail end of the longitudinal guide rail 2022, then release the clamping and send them to the transfer unit 4000. In this way, the processing efficiency and quality can be improved, the automated production can be realized, and the problem of the welded transverse reinforcement of the composite stirrups relying entirely on manual assembly welding can be avoided.

[0074] Please see again Figure 10-12, wherein the longitudinal guide rail 2022 is fixedly connected to the lower connecting frame 2015 through a base plate 2021. During implementation, the base plate 2021 can be made of square steel pipe. The base plate 2021 is also provided with a driving unit 2024, and drives the clamping unit 2023 to slide along the longitudinal guide rail 2022 through a screw transmission method; the clamping unit 2023 includes a nut seat 2231 that is transmission-connected to a screw rod 2241 of the driving unit 2024, and a structural plate 2232 is connected to the side of the nut seat 2231 away from the lower connecting frame 2015, and one end of the structural plate 2232 is connected to a main clamping arm 2233 extending along the length direction of the longitudinal guide rail 2022. The main clamping arm 2233 One end of the holding arm 2233 is hinged to the upper part of one end of the structural plate 2232, and the free end of the main clamping arm 2233 is bent upward to form a main claw 2234. A first telescopic cylinder 2235 is provided between the lower part of one end of the structural plate 2232 and the free end of the main clamping arm 2233 to drive the main clamping arm 2233 to rotate along its hinged end to facilitate the adjustment of the height of the main claw 2234. The free end of the main clamping arm 2233 is also hinged with a secondary claw 2236 that cooperates with the main claw 2234 to form a clamping mouth 2238. The main clamping arm 2233 is provided with a second telescopic cylinder 2237 for driving the secondary claw 2236 to rotate so as to complete the clamping and releasing actions accordingly.

[0075] In this way, a specific form of an implementable feeding mechanism 2002 is provided, in which the main claw 2234 and the auxiliary claw 2236 that cooperate to form the clamping mouth 2238 can adjust the height under the action of the first telescopic cylinder 2235, so as to better realize the related clamping and sliding mechanism actions, improve the functional design, and have a simple and reliable structure.

[0076] Among them, the lower surface of the free end of the main clamping arm 2233 is protruded with a first articulated seat 2331, and the two ends of the first telescopic cylinder 2235 are respectively hinged to the lower ends of the structural plate 2232 and the first articulated seat 2331; in the length direction of the horizontal guide rail 2003, the thickness of the main claw 2234 and the auxiliary claw 2236 correspond and the superimposed thickness of the two corresponds to the main clamping arm 2233, and the lower surface of the hinged end of the main clamping arm 2233 is protruded with a second articulated seat 2332, the second telescopic cylinder 2237 is hinged to the second articulated seat 2332, the piston rod of the second telescopic cylinder 2237 passes through the first articulated seat 2331 and is hinged to the lower end of the auxiliary claw 2236, the middle part of the auxiliary claw 2236 is hinged to the main claw 2234, and the upper end of the auxiliary claw 2236 cooperates with the upper end of the main claw 2234 to form the clamping mouth 2238.

[0077] In this way, the structure of the feeding mechanism 2002 is compact, and the thickness of the feeding mechanism 2002 (in the length direction of the horizontal guide rail 2003) can be reduced as much as possible, so that the two welding butts can be closer when adjusting the spacing, thereby being suitable for the welding processing of stirrups with smaller widths and improving applicability.

[0078] Among them, the screw 2241 of the driving unit 2024 is arranged in parallel above the longitudinal guide rail 2022, and its two ends are respectively connected to the connecting seat 2243 and the motor 2242 arranged on the base plate 2021; the lower end of the nut seat 2231 is connected to the longitudinal guide rail 2022 through a guide rail groove 2239 adapted to the longitudinal guide rail 2022.

[0079] In this way, the transmission connection and movement stability of the clamping unit 2023 are ensured.

[0080] Please see again Figure 8 , Fig. 9 , wherein the two horizontal guide rails 2003 are laid on the steel frame 2004, and the welding machine 2001 is erected on the horizontal guide rails 2003 through a flatbed trolley 2005 to improve flexibility. A driving screw 2043 is provided in the steel frame 2004 below the flatbed trolley 2005, and the driving screw 2043 is composed of two external thread segments with opposite rotation directions. The two flatbed trolleys 2005 are respectively connected to the driving screw 2043 through transmission seats 2051 corresponding to the two external thread segments with opposite rotation directions. The transmission seat 2051 is convexly connected to the lower surface of the flatbed trolley 2005, and the two ends of the driving screw 2043 are respectively rotatably connected to the connecting rotating seat 2042, and the connecting rotating seat 2042 is fixedly connected in the steel frame 2004, and either end of the driving screw 2043 is connected to a driving motor 2045. The middle part of the driving screw 2043 can rotate through the support seat 2044 fixedly connected to the steel frame 2004 to ensure the rigidity of the driving screw 2043. In implementation, the steel frame 2004 can be a square frame structure formed by connecting H-shaped steels end to end, and the connecting rotating seat 2042 and the support seat 2044 are fixedly connected to the steel frame 2004 through the connecting plates 2041 arranged at intervals in the steel frame 2004.

[0081] For ease of understanding, the movement process of the welding machine unit 2000 is further introduced. When implemented, for ease of control, the transformer, the clamping cylinder 2013, the first telescopic cylinder 2235, the second telescopic cylinder 2237, the motor 2242, and the drive motor 2045 in the main body 2011 of the welding machine 2001 can be electrically connected to the PLC controller. The mechanism movements of the two welding machines 2001 and related mechanisms are synchronized. When in use,

[0082] 1) The PLC controller controls the driving motor 2045 to rotate and adjusts the distance between the two pairs of welding machines 2001 so that the distance between the lower clamps 2016 of the two pairs of welding machines 2001 corresponds to the length of the transverse reinforcement of the stirrup to be welded;

[0083] 2) The PLC controller controls the motors 2242 of the two feeding mechanisms 2002 to rotate synchronously, driving the two clamping units 2023 to move to the front end of the longitudinal guide rail 2022;

[0085] 4) The PLC controller controls the motor 2242 to rotate, and the two clamping units 2023 feed the stirrups horizontally. The longitudinal bars on both sides of the stirrups are placed on the two lower clamps 2016 respectively, and the feeding is stopped according to the designed welding position. The welding transverse bar feeding unit 3000 puts the welding transverse bars of the same length as the transverse bars of the stirrups;

[0086] 5) The PLC controller controls the pressing cylinder 2013 to extend, the upper clamp 2014 to move downward, the PLC controller controls the transformer to energize, and the upper clamp 2014 cooperates with the lower clamp 2016 to weld the two ends of the welded transverse reinforcement to the longitudinal reinforcements on both sides of the stirrups;

[0087] 6) The PLC controller controls the clamping cylinder 2013 to retract and the upper chuck 2014 to move upward;

[0088] 7) Repeat the above steps 4), 5), and 6) until the last transverse reinforcement to be welded is completed, keep the upper chuck 2014 and the lower chuck 2016 clamping the stirrup, the PLC controller controls the second telescopic cylinder 2237 to retract, the auxiliary claw 2236 and the main claw 2234 to release, the PLC controller controls the first telescopic cylinder 2235 to retract, the auxiliary claw 2236 and the main claw 2234 to drop to below the transverse reinforcement of the stirrup to avoid it, and prepare for sliding;

[0091] 10) The PLC controller controls the clamping cylinder 2013 to retract and the upper chuck 2014 to move upward;

[0092] 11) The PLC controller controls the motor 2242 to rotate, driving the two clamping units 2023 to slide to the end of the longitudinal guide rail 2022;

[0093] 12) The PLC controller controls the second telescopic cylinder 2237 to retract, and the auxiliary claw 2236 and the main claw 2234 are loosened, so that the composite stirrups are delivered and received by the transfer unit 4000. The PLC controller controls the first telescopic cylinder 2235 to retract, and the auxiliary claw 2236 and the main claw 2234 are lowered to prepare for the next clamping.

[0094] See also Figure 13-15 The welding cross-rib feeding unit 3000 includes a frame 3001, on which two corresponding left and right moving frames 3003 are arranged. Each moving frame 3003 can move left and right on the frame 3001, and its moving method can adopt a slide groove method. A slide groove is arranged on the frame 3001, so that the moving frame 3003 can slide left and right along the slide groove, but is not limited to this. At the same time, two corresponding base plates 3002 are arranged on the frame 3001, and the moving frame 3003 is located between the two base plates 3002. A support rod 3005 is arranged between the two base plates 3002. The base plates 3002 are arranged to protect the moving frame 3003, and at the same time, they play a role of moving limit for the moving frame 3003, wherein a hand wheel 3004 is arranged on the outer side of one base plate 3002, and a first motor 3019, a second motor 3020 and a third motor 3018 are arranged on the outer side of the other base plate 3002.

[0095] At the same time, in order to more conveniently drive the mobile frame 2 to move, a screw rod 3013 is arranged between the two mobile frames 3003. The screw rod 3013 cooperates with the nut, and the screw rod 3013 is connected to the hand wheel 3004. The hand wheel 3004 controls the rotation of the screw rod 3013 to drive the mobile frame 3003 to move and adjust the distance between the two mobile frames 3003.

[0096] The inner side of each mobile frame 3003 is sequentially provided with a vibrating member, a quantitative conveying member and a loading manipulator 3022 according to the loading process, so that the welding cross ribs can be loaded through the loading manipulator 3022 when the two clamping units 2023 slide and stop for welding; the vibrating member includes a first driving wheel, a first driven wheel and a first transmission chain 3011 wound between the first driving wheel and the first driven wheel, a third rotating shaft is sleeved on the middle part of the first driving wheel, a first rotating shaft 3006 is provided on the frame 3001, the first rotating shaft 3006 is connected to a first motor 3019 provided on the frame 3001, and a third motor 3018 is connected to the third rotating shaft, through the first motor 3019 and The third motor 3018 realizes automatic transportation; the first driven wheel is idle on the first rotating shaft 3006, and a ratchet 3007 is arranged on the first rotating shaft 3006. A limit plate 3008 is sleeved on the outer edge of the upper semicircle of the ratchet 3007. The lower side of the support rod 3005 is fixedly connected to the limit plate 3008, and the function of the support rod 3005 is to support the limit plate 3008; a conveying channel for clamping and transporting the welding transverse reinforcement is formed between the inner side surface of the limit plate 3008 and the ratchet 3007, and the conveying channel is higher than the first transmission chain 3011, so that when the welding transverse reinforcement is transported in the conveying channel, the first transmission chain 3011 does not form position interference with the two ends of the welding transverse reinforcement.

[0097] The quantitative conveying member includes a second driving wheel, a second driven wheel, and a second transmission chain 3014 wound between the second driving wheel and the second driven wheel, wherein the second driven wheel is loosely sleeved on the screw rod 3013, so that when the screw rod 3013 rotates, it will not drive the second driven wheel to rotate, and the structural design is compact.

[0098] In addition, the frame 3001 is provided with a second rotating shaft 3015 connected to the second motor 3020, the second rotating shaft 3015 is provided with a pulley located on the outer side of the movable frame 3003, the outer side of the movable frame 3003 is provided with a rotating rod 3021 coaxial with the second driving wheel, and a transmission belt 3016 is provided between the rotating rod 3021 and the pulley; the pulley is driven to rotate by the second rotating shaft 3015, and the rotation of the pulley drives the rotating rod 3021 to rotate, further causing the second driving wheel to rotate, and then causing the second transmission chain 3014 to rotate. This design allows the second transmission chain 3014 to mitigate impact and vibration during operation, and move smoothly and without noise.

[0099] At the same time, the second transmission chain is arranged corresponding to the position of the ratchet wheel. The outer surface of the second transmission chain 3014 is provided with a plurality of protruding spikes. Between adjacent spikes is a storage cavity for conveying welding transverse ribs. The two ends of each welding transverse rib are respectively placed in the storage cavity. The storage cavity corresponds to a single welding transverse rib, so that the welding transverse rib in the conveying channel is input from the output end of the conveying channel to the second transmission chain 3014. A limiting material block 3017 is arranged at the end of the second transmission chain 3014 away from the ratchet wheel. The limiting material block 3017 is hook-shaped as a whole. The end of the limiting material block 3017 close to the second transmission chain 3014 is an inclined smooth section, and the smooth section is located below the second transmission chain 3014. The end of the limiting material block 3017 away from the second transmission chain 3014 is bent upward to form a material storage section. This design makes the smooth section seamlessly connected with the second transmission chain 3014. When the welding transverse rib enters the limiting material block 3017, the inclined smooth section provides the welding transverse rib with a downward force, so that the welding transverse rib enters the limiting material block 30 17 of the material storage section, and limits only a single welding transverse rib, thereby controlling the quantitative delivery of the welding transverse rib; the feeding manipulator 3022 is located on the inner side of the limiting block 3017 so as to clamp the welding transverse rib that falls into the material storage section near the middle, thereby facilitating the feeding and welding. The mobile driving mechanism of the feeding manipulator 3022 is arranged on the outer side of the moving frame 3003, and the mobile driving mechanism includes a telescopic cylinder and a directional reciprocating sliding guide rail. The outer side of the feeding manipulator 3022 is through the guide rail groove It cooperates with the directional reciprocating sliding guide rail and slides along it under the drive of the telescopic cylinder. The loading robot 3022 can also realize the vertical telescopic movement of the lower part through the cylinder of its own structure and has a pair of clamping blocks at the lower part that can be clamped by the cylinder. The lower part of the two loading robots 3022 clamps the welding cross ribs and then retracts upward, avoiding the hook-shaped part of the limiting block 3017, and slides along the directional reciprocating sliding guide rail under the drive of the telescopic cylinder to the front end loading position for loading.

[0100] A rectangular convex plate 3010 is provided on the mobile frame 3003, and the convex plate 3010 is located between the first driving wheel and the first driven wheel, so that the first transmission chain 3011 is wound on the convex plate 3010. In this design, the rectangular convex plate 3010 supports the first transmission chain 3011. At the same time, when the welding transverse ribs are placed, the welding transverse ribs are in a horizontal state. Moreover, when the first transmission chain 3011 moves, the first transmission chain 3011 and the convex plate 3010 generate friction and vibration, thereby realizing vibration dispersion and transportation of the welding transverse ribs.

[0101] The movable frame 3003 is provided with an inclined guide plate 3009, which is located above the first transmission chain 3011 and at the end of the first transmission chain 3011 away from the ratchet wheel 3007. This design facilitates the welding cross bar to slide from the guide plate 3009 to the first transmission chain 3011. At the same time, a feeding chamber for placing the welding cross bar is formed between the guide plate 3009 and the limit plate 3008. The welding cross bar is horizontally placed between the left and right guide plates 3009, so that the welding cross bar vibrates and feeds in the chamber.

[0102] For ease of understanding, the movement process of the welding transverse rib feeding unit 3000 is further described. The distance between the two moving frames 3003 is moved by the hand wheel 3004 so that the distance between the two moving frames 3003 is adapted to the size of the welding transverse ribs, so that it can be adapted to the transportation of welding transverse ribs of various sizes. After the moving frame 3003 is adjusted, multiple welding transverse ribs are placed on the guide plate 3009 and slid onto the first transmission chain 3011, or directly placed on the first transmission chain 3011, and the first driving wheel is driven to rotate through the third rotating shaft, and the first driving wheel drives the first transmission chain 3011 to rotate. At the same time, the first rotating shaft 3006 is driven to rotate through the first motor 3019, so that the first rotating shaft 3006 drives the ratchet wheel 3007 to rotate. Since the first driven wheel and the first rotating shaft 3006 are empty sleeves, the first rotating shaft 3006 will not drive the first driven wheel to rotate. At this time, the ratchet 3007 is rotating. Since there are multiple tooth grooves on the ratchet 3007, each tooth groove corresponds to a welding transverse rib. Therefore, the welding transverse ribs transported from the first transmission chain 3011 to the ratchet 3007 can only enter the tooth grooves on the outer edge of the ratchet 3007 one by one in sequence, and each tooth groove enters a welding transverse rib; when the ratchet 3007 continues to rotate, the welding transverse rib enters the conveying channel, and at the same time, the ratchet 3007 rotates to the limit plate 3008, blocking other welding transverse ribs from entering the tooth groove, while other welding transverse ribs will enter other tooth grooves of the ratchet 3007; at this time, the limit plate 3008 and the tooth grooves of the ratchet 3007 form a clamping force on the welding transverse ribs. When the ratchet 3007 continues to rotate, it drives the welding transverse rib to be transported to the second transmission chain 3014, and the welding transverse rib falls onto the second transmission chain 3014. The spikes on the second transmission chain 3014 prevent the welding transverse rib from sliding downward, and drive the welding transverse rib to be transported to the limiting block 3017, and the single welding transverse rib is transported through the limiting block 3017. In this way, quantitative transportation of the welding transverse rib is realized, so that the welding transverse rib is automatically arranged neatly and orderly into the workplace during transportation; then the loading robot 3022 clamps the welding transverse rib that falls into the storage section of the limiting block 3017 and feeds it to the welding machine unit 3000, which is adapted to the sliding stop of the two clamping units 2023 to cooperate with the welding action.

[0103] The welding cross bar feeding unit 3000 has a material storage function, and does not need frequent manual feeding. By controlling the first rotating shaft 3006 and the third rotating shaft, the transportation and unloading of the welding cross bars are realized at the same time, which effectively simplifies the mechanical structure. The welding cross bars are transported in fixed sizes by setting the mobile frame 3003, and the ratchet 3007 and the limit plate 3008 are used to quickly locate and transport the welding cross bars to the specified position, with high positioning efficiency; and the ratchet 3007 is used to drive multiple welding cross bars to move, so that multiple welding cross bars can be transported at the same time, which improves the transportation efficiency.

The sliding rods are perpendicular to the rolling rollers 4004. The sliding rods are slidably connected to the moving rods perpendicular thereto.

The claws 4010 are hook-shaped as a whole, and the lower ends of the claws 4010 are provided with bending portions bent inward.

[0109] A first screw rod 4011 for driving the moving rod is provided below the rotating frame 4009 . The first screw rod 4011 cooperates with a nut. The first screw rod 4011 is connected to a first driving motor 4012 provided on the rotating frame 4009 . The first driving motor 4012 is electrically connected to a PLC controller.

[0110] When the second servo motor 4017 drives the rotating part to move downward, the rotating plate 4008 drives the claw hand 4010 to gradually approach the rolling roller 4004, and makes the bent part of the claw hand 4010 located below the rolling roller 4004, and the first screw rod 4011 drives the two moving rods to move left and right on the sliding rod, and gradually move closer to the composite stirrups, so that the bent part of the claw hand 4010 is against the composite stirrups, and when the second servo motor 4017 drives the sliding plate 4013 to lift upward, the bent part lifts the composite stirrups, so that the composite stirrups are away from the conveying frame.

[0111] The third servo motor 4007 is started, and the output shaft of the third servo motor 4007 drives the rotating plate 4008 to rotate, the rotating plate 4008 drives the rotating frame 4009 to rotate, and the rotating frame 4009 drives the moving rod to rotate. According to the instructions sent by the PLC controller, it usually rotates 90 degrees to change the original horizontal direction to the vertical direction so as to form a composite stirrup with a "well"-shaped welded transverse reinforcement inside for the second welding. When necessary, it can also slide to the storage frame position through the sliding plate 4013 to directly unload.

[0112] The first positioning member 4015 and the second positioning member 4016 both include a first sensor and a telescopic rod sequentially arranged along the transmission direction of the composite stirrup, a cylinder connected to the telescopic rod is arranged at the bottom of the telescopic rod, and a fourth controller connected to the cylinder is arranged on the cylinder, wherein the second positioning member 4016 is provided with a limit plate 4005 movable to adjust the distance between the two on both sides; the PLC controller is electrically connected to the first sensor, and the PLC controller is electrically connected to the first controller, the second controller, the third controller and the fourth controller respectively. During implementation, the second positioning member 4016 and the limit plate 4005 can adopt the same structure of the telescopic positioning rod 1100 and the limit unit on the stirrup feeding unit 1000.

The conveying frame 4003 is sleeved in the reversing frame 4001 .

[0114] For ease of understanding, the movement process of the transfer unit 4000 is further introduced. After the two clamping units 2023 of the first welding machine unit 2000 release the composite stirrups after one welding at the tail end of the longitudinal guide rail 2022, they are received on the conveyor frame 4003. As the conveyor frame 4003 is transported, the composite stirrups approach the first sensor of the first positioning member 4015. When the first sensor of the first positioning member 4015 detects information, it sends the information to the PLC controller. At this time, the PLC controller first sends instructions to the fourth controller, so that the fourth controller starts the cylinder; the telescopic rod extends from the cylinder to block the composite stirrups from continuing to be transported. Then, the PLC controller sends instructions to the second controller, and the second controller starts the second servo motor 4017. The second servo motor 4017 drives the rotating member to move downward through the screw linear module. The rotating plate 4008 drives the claw hand 4010 to gradually approach the rolling roller 4004, and makes the bending part of the claw hand 4010 located below the rolling roller 4004. The first screw rod 4011 The two moving rods are driven to move left and right on the sliding rod and gradually approach the composite stirrups, so that the bent portion of the claw hand 4010 is against the composite stirrups and clamps the composite stirrups. When the second servo motor 4017 drives the rotating plate 4008 to lift upward, the bent portion grabs the composite stirrups and the telescopic rod is reset; the PLC controller sends a command to the third controller, the third controller starts the third servo motor 4007, and the third servo motor 4007 drives the rotating plate 4008 to rotate. At this time, the rotating plate 4008 moves the claw hand After 4010 rotates 90°, the PLC controller sends a command to the second controller, and the second controller controls the second servo motor 4017 to drive the rotating member to move downward, and the claw hand 4010 releases the composite stirrup, so that the composite stirrup falls on the conveying frame 4003 and continues to be conveyed; when the composite stirrup is transported to the position of the second positioning member 4016, the telescopic rod of the second positioning member 4016 extends to prevent the composite stirrup from continuing to be transported, and the spacing of the limit plate 4005 cooperates with the composite stirrup to achieve guided conveying of the composite stirrup. After the second welding machine unit 5000 of the subsequent process horizontally undertakes to grasp the composite stirrup, the PLC controller controls the telescopic rod of the second positioning member 4016 to descend, and the second welding machine unit 5000 horizontally pulls out the composite stirrup and then implements the second welding. The welding process and the loading process are the same as the actions of the first welding machine unit 2000 and the welding transverse reinforcement loading unit 3000 mentioned above, and will not be repeated. After the second welding, the composite stirrup with a "well"-shaped welding transverse reinforcement inside is formed.

[0115] The unloading unit 6000 also includes a conveying frame 4003, which is combined with the two clamping units of the second welding unit 5000 to slide and unload the composite stirrups after the secondary welding, and the composite stirrups are received by the unloading unit 6000 and continue to be transported and unloaded. The unloading unit 6000 can also be designed more flexibly, such as in this embodiment. Figure 1 , Figure 2In the unloading unit 6000, a reversing frame 4001 and related structures like those in the transfer unit 4000 are also provided. Thus, when unloading, the unloading material can be directly transported to the rear of the conveying frame, or unloaded to the storage frame position on the side of the conveying frame by means of claws, and the angle posture of the composite stirrups during unloading can be changed by rotating the plate, which is flexible.
