Description

Technical Field

[0001] This invention relates to the field of cold pressing connection machine technology, specifically a CNC cold pressing connection machine for steel bars. Background Technology

[0002] Reinforcing bars are steel materials used in reinforced concrete and prestressed reinforced concrete engineering. In concrete structures, reinforcing bars mainly bear tensile stress. Among them, deformed reinforcing bars can form a stronger bond with concrete by means of the interlocking of surface ribs. Reinforcing bar connection is an indispensable key process in reinforcing bar engineering construction. Traditional connection processes mostly use steel wire binding or welding to fix the reinforcing bars. However, the mechanical strength of the connection nodes is insufficient, and the joints are very prone to breakage. The cold-pressing connection machine uses a hydraulic system to drive the extrusion die, applying precise pressure to the sleeve to cause plastic deformation. The sleeve flows along the ribs of the steel bar to form a mechanical interlock. However, the cold-pressing connection machine usually requires manual support to approach the steel bar connection point, adjust the position of the sleeve close to the steel bar connection, and perform the cold-pressing operation. It cannot reduce the manual support and adjustment position, reduce the distance of workers from the cold-pressing machine, avoid unnecessary damage to workers caused by the building structure, and reduce the labor occupation. Summary of the Invention

[0003] The purpose of this invention is to provide a CNC cold pressing and connecting machine for reinforcing bars to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A CNC cold pressing connection machine for reinforcing bars includes a cold pressing assembly for cold pressing and assembling sleeves at the ends of two reinforcing bars. The cold pressing assembly includes a cold pressing machine body, an upper clamp is provided near the top on the outer wall of the cold pressing machine body, and a lower clamp that moves up and down is also provided on the outer wall of the cold pressing machine body. The operating component is used for CNC control to position and clamp the sleeves fitted on steel bars of different thicknesses at the end and perform cold pressing clamping. The operating component includes two sets of symmetrical top plates. Each top plate has a shoulder plate on both sides. Several screws are provided between the two shoulder plates in the same vertical direction. Each screw has a storage plate and an arm plate on one side from one end to the other. The storage plate is equipped with a limit adjustment for the movable plate on the outer wall of the sleeve. The movable plate is slidably connected in the storage plate, and the upper surface of the storage plate is equipped with a drive motor for moving the movable plate.

[0005] Furthermore, the upper caliper and the main body of the cold press are integrally formed. The front end of the upper caliper is provided with a rib groove, and the upper caliper groove is symmetrically opened at the edge of the rib groove.

[0006] In this invention, the straightening groove facilitates the passage of the corresponding reinforcing bar, and with the cooperation of the upper clamp groove, it helps the limiting structure at the end of the corresponding movable plate to be fixedly inserted and installed.

[0007] Specifically, the lower caliper is slidably connected to the cold press body via a hydraulic rod. The lower caliper has another rib-aligning opening at the position corresponding to the rib-aligning opening in the upper caliper. The lower caliper has symmetrically formed lower caliper grooves at the edge of the rib-aligning opening.

[0008] In this invention, the rib-aligning notch on the lower clamp corresponds to the rib-aligning notch on the upper clamp, which facilitates the insertion of two sections of reinforcing bars. With the cooperation of the groove in the lower clamp, the limiting structure at the end of the lower movable plate is fixedly inserted, increasing the stable snap-fit ​​installation of the two sets of movable plate ends and limiting the position of the sleeve.

[0009] It should be noted that the two top plates are respectively fitted onto both ends of the cold press body and fixed with bolts. The shoulder plates are respectively snapped into the two ends of the top plates and fixed with bolts. The screws pass through the shoulder plates and are located on both sides of the shoulder plates and fixed with nuts.

[0010] In this invention, the top plate provides an installation point for the shoulder plate, the screw connects the two shoulder plates, and the stability of the shoulder plate installation is increased by multiple sets of nut thread connections.

[0011] Furthermore, a connecting plate is provided on one side of the outer wall of the lower caliper. The connecting plate is fixed to one side of the arm plate by bolts. Each arm plate is provided with a cylinder. The cylinder is fixed to the arm plate by bolts. The piston rod of the cylinder passes through the arm plate and is fixed to the bottom of the storage plate by bolts. The storage plate slides on the screw.

[0012] In this invention, the cylinder provides the power for up-and-down adjustment, enabling the storage plate to move up and down in the screw. With the cooperation of the connecting plate, the arm plate on one side and the lower clamp move up and down synchronously. When the lower clamp moves up to cold press the sleeve and the steel bar, it avoids the movable plate on the storage plate not being able to move with it, thus affecting the cold pressing fit.

[0013] Secondly, nuts are provided on both sides of the arm plate on the screw on the other side, and the nuts fix the position of the arm plate on the other side.

[0014] In this invention, the arm plate on the other side is fixed to the screw with the help of a nut, so that the movable plate can be assembled and used in conjunction with the corresponding upper caliper.

[0015] It is worth noting that the storage plate consists of two fixed plates, the drive motor is fixed to the fixed plates by bolts, several rollers are provided in the middle of the storage plate, the movable plate is inserted and engaged with the storage plate, the movable plate is arc-shaped, a toothed plate is provided at one end of the movable plate extending into the inside of the storage plate, and gears that mesh with the toothed plates are symmetrically provided in the middle of the storage plate, and the output shaft of the drive motor is connected to the rotating shaft of one of the gears through a coupling.

[0016] In this invention, the control switch on the outer wall of the drive motor is electrically connected to an external power source via a wire to control the forward and reverse rotation of the output shaft, thereby realizing the forward and reverse rotation of the corresponding gear. With the meshing of the cleat plate and the gear, the movable plate can be stored or extended for adjustment. The movable plate is stored in the storage plate, which facilitates the corresponding insertion and cooperation between the corresponding steel bar with the sleeve and the main body of the cold press. The extension of the storage plate helps to assemble and use with the corresponding upper and lower calipers.

[0017] Among them, there are several rollers in the middle of the storage plate near the outer wall. The rollers are rotatably connected to the storage plate. With the cooperation of the rollers, they fit and contact the outer wall of the movable plate, so as to realize the flexible sliding cooperation of the movable plate.

[0018] In addition, the movable plate has a movable pressure cylinder at its end, and the movable pressure cylinder has locking blocks on both sides and at the corresponding upper and lower caliper grooves. The locking blocks and the movable pressure cylinder are integrally formed, and the movable plate and the locking tooth plate are integrally formed.

[0019] In this invention, the locking block is inserted into the corresponding upper and lower caliper grooves, which helps the movable pressure cylinder to be locked into the corresponding upper and lower caliper grooves, increasing the stability of the installation and reducing the impact of sleeve breakage at the rebar connection under cold pressing.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides the power for the lower caliper to move up and down by setting the main body of the cold press. The top plate is fixedly combined with the main body of the cold press, and the shoulder plate is correspondingly combined with the top plate. Multiple screws provide stability for the shoulder plate combination on the same vertical plane. The storage plate, movable plate, and arm plate are all slidably installed on the screws and are fixed in their respective positions by nuts. The storage plate is equipped with a drive motor to realize the movable plate with the cleat plate being stored or extended in the storage plate. The corresponding movable pressure cylinder is inserted into the corresponding upper caliper groove and lower caliper groove through the cleat block to increase the stability of the combination.

[0021] 2. This invention sets two gears that mesh with the toothed plate. One of the gears is connected to the output shaft of the drive motor via a coupling. The drive gear provides the power for forward and reverse rotation, enabling the toothed plate to move forward and extend to the upper and lower caliper positions. With the cooperation of the cylinder, the movable pressure cylinder is inserted and installed accordingly. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-8 This embodiment provides a technical solution: A CNC cold pressing connection machine for steel bars includes a cold pressing assembly. The cold pressing assembly is used for cold pressing the upper sleeves at the ends of two steel bars. The cold pressing assembly includes a cold pressing machine body 1. An upper clamp 10 is provided on the outer wall of the cold pressing machine body 1 near the top. A lower clamp 11 that moves up and down is also provided on the outer wall of the cold pressing machine body 1. Furthermore, the upper caliper 10 and the main body 1 of the cold press are integrally formed. The upper caliper 10 has a rib-straightening opening at the front end, and the upper caliper 10 has symmetrical upper caliper grooves 100 at the edge of the rib-straightening opening.

[0026] In this invention, the straightening groove facilitates the passage of the corresponding reinforcing bar, and with the cooperation of the upper clamp groove 100, it helps the limiting structure at the end of the corresponding movable plate 5 to be fixedly inserted and installed.

[0027] Specifically, the lower caliper 11 is slidably connected to the cold press body 1 via a hydraulic rod. Another rib-aligning opening is provided on the lower caliper 11 at the position corresponding to the rib-aligning opening in the upper caliper 10. The lower caliper 11 has symmetrically provided lower caliper grooves 110 at the edge of the rib-aligning opening.

[0028] In this invention, the rib-aligning opening on the lower clamp 11 corresponds to the rib-aligning opening on the upper clamp 10, which facilitates the insertion of two sections of reinforcing bars. With the cooperation of the lower clamp groove 110, the limiting structure at the end of the lower movable plate 5 is fixedly inserted, increasing the stable snap-fit ​​installation of the ends of the two sets of movable plates 5, and limiting the position of the sleeve.

[0029] Furthermore, a connecting plate 12 is provided on one side of the outer wall of the lower caliper 11. The connecting plate 12 is fixed to one side of the arm plate 6 by bolts. Each arm plate 6 is provided with a cylinder 60. The cylinder 60 is fixed to the arm plate 6 by bolts. The piston rod of the cylinder 60 passes through the arm plate 6 and is fixed to the bottom of the storage plate 4 by bolts. The storage plate 4 slides on the screw 30.

[0030] In this invention, the cylinder 60 provides the power for up-and-down adjustment, enabling the storage plate 4 to move up and down in the screw 30. With the cooperation of the connecting plate 12, the arm plate 6 on one side and the lower clamp 11 move up and down synchronously. When the lower clamp 11 moves up to cold press the sleeve and the steel bar, it prevents the movable plate 5 on the storage plate 4 from not moving with it, thus affecting the cold pressing.

[0031] It should be noted that the operating component is used for CNC control to position and clamp the sleeves on steel bars of different thicknesses at the end and perform cold pressing clamping. The operating component includes two sets of symmetrical top plates 2, and shoulder plates 3 are provided on both sides of the top plates 2. Several screws 30 are provided between the two shoulder plates 3 in the same vertical direction. A storage plate 4 and an arm plate 6 are provided on one side of the screw 30 from one end to the other. Furthermore, the two top plates 2 are respectively fitted onto both ends of the cold press body 1 and fixed with bolts. The shoulder plates 3 are respectively snapped into the two ends of the top plates 2 and fixed with bolts. The screws 30 pass through the shoulder plates 3 respectively, and the screws 30 are located on both sides of the shoulder plates 3 and fixed with nuts.

[0032] In this invention, the top plate 2 provides an installation point for the shoulder plate 3, the screw 30 connects the two shoulder plates 3, and the stability of the shoulder plate 3 installation is increased by multiple sets of nut thread connections.

[0033] Secondly, nuts are provided on both sides of the arm plate 6 on the other screw 30, and the nuts fix the position of the other arm plate 6.

[0034] In this invention, the arm plate 6 on the other side is fixed to the screw 30 with the help of a nut, so that the movable plate 5 and the corresponding upper caliper 10 can be assembled and used in a corresponding manner.

[0035] The storage plate 4 is provided with a limit adjustment 5 for the movable plate on the outer wall of the sleeve. The movable plate 5 is slidably connected in the storage plate 4. The upper surface of the storage plate 4 is provided with a drive motor 40 for moving the movable plate 5.

[0036] It is worth noting that the storage plate 4 consists of two fixed plates. The drive motor 40 is fixed to the fixed plates by bolts. Several rollers 41 are provided in the middle of the storage plate 4. The movable plate 5 is inserted and engaged with the storage plate 4. The movable plate 5 is arc-shaped. One end of the movable plate 5 extending into the inside of the storage plate 4 is provided with a toothed plate 51. Gears 42 that mesh with the toothed plates 51 are also symmetrically provided in the middle of the storage plate 4. The output shaft of the drive motor 40 is connected to the rotating shaft of one of the gears 42 through a coupling.

[0037] In this invention, the control switch on the outer wall of the drive motor 40 is electrically connected to an external power source via a wire to control the forward and reverse rotation of the output shaft, thereby realizing the forward and reverse rotation of the corresponding gear 42. With the meshing of the toothed plate 51 and the gear 42, the movable plate 5 can be stored or extended for adjustment. The movable plate 5 is stored in the storage plate 4, which facilitates the corresponding steel bar with the sleeve to be inserted and matched with the cold press body 1. The extension of the storage plate 4 helps to be assembled and used with the corresponding upper clamp 10 and lower clamp 11.

[0038] Among them, the storage plate 4 is provided with several rollers 41 near the outer wall surface in the middle. The rollers 41 are rotatably connected to the storage plate 4. With the cooperation of the rollers 41, they fit and contact the outer wall surface of the movable plate 5, so as to realize the flexible sliding cooperation of the movable plate 5.

[0039] In addition, the movable plate 5 has a movable pressure cylinder 50 at its end, and the movable pressure cylinder 50 has a locking block 500 on both sides and at the corresponding upper caliper groove 100 and lower caliper groove 110. The locking block 500 and the movable pressure cylinder 50 are integrally formed, and the movable plate 5 and the locking tooth plate 51 are integrally formed.

[0040] In this invention, the locking block 500 is inserted into the corresponding upper clamp groove 100 and lower clamp groove 110, which helps the movable pressure cylinder 50 to be locked into the corresponding upper clamp 10 and lower clamp 11 grooves, increasing the stability of installation and reducing the impact of sleeve breakage at the rebar connection under cold pressing.

[0041] In this embodiment of the steel bar CNC cold pressing connection machine, the upper clamp with the upper clamp groove 100 is first combined with the cold pressing machine body 1, and the lower clamp 11 with the lower clamp groove 110 is combined with the cold pressing machine body 1. Then, the corresponding two top plates 2 are fixed to both ends of the cold pressing machine body 1. Then, the shoulder plate 3 is fixed to the outside of the top plate 2 by bolts. A screw 30 is provided between the two shoulder plates 3 in the same vertical direction and fixed by nuts. The arm plate 6 with the cylinder 60 is sleeved on the screw 30. Then, the movable plate 5 with the toothed plate 51 is inserted into the corresponding storage plate 4, and multiple roller shafts 41 are rotatably connected to the storage plate 4. The gear 42 is rotatably connected to the storage plate 4 and meshes with the toothed plate 51. The drive motor 40 is fixed on the storage plate 4, and the output shaft is connected to the rotating shaft of one of the gears 42 through a coupling. The connecting plate 12 on one side of the lower caliper 11 is fixed to the corresponding arm plate 6 by bolts. The lower caliper 11 moves up and down, causing the corresponding arm plate 6 with cylinder 60 to move up and down, thereby realizing that the storage plate 4 connected to the piston rod end of cylinder 60 moves up and down in screw 30, and realizing that the corresponding movable plate 5 moves up and down with the lower caliper 11. The two rebar ends are connected by inserting a sleeve with a steel needle. The steel needle is located in the middle of the sleeve, restricting the position of the two rebar ends. Then, the main body 1 of the cold press is lifted by the steel cable of an external hoist. External force is used to insert the rib-aligning openings in the upper clamp 10 and lower clamp 11 with the corresponding rebars. Then, according to the position of the sleeve, the piston rod of the cylinder 60 is controlled to move, so that the movable plate 5, the movable pressure cylinder 50 and the corresponding upper clamp 10 and lower clamp 11 are kept horizontal. Then, according to the position of the rib-aligning opening, the drive motor 40 is started, so that the toothed plate 51 moves, thereby realizing... The movable pressure cylinder 50 is positioned at the joint of the reinforcing bar. Then, the piston rod of the control cylinder 60 is extended and retracted, so that the clamping block 500 is inserted into the corresponding upper clamping groove 100 and lower clamping groove 110 respectively, limiting the position of the sleeve side wall. Finally, the hydraulic rod of the cold press body 1 is retracted, so that the lower clamping 11 moves to the upper clamping 10, realizing the cold pressing and fixing of the corresponding sleeve and the reinforcing bar. The hoist, drive motor 40, and cylinder are all connected to the external CNC panel through wires. By adjusting the corresponding parameters, the reinforcing bar can be cold-pressed and connected without manual support.
