DETAILED DESCRIPTION

[0022] In order to better understand the purpose, structure and function of the utility model, the utility model of a threaded steel butt joint device is further described in detail below in combination with the drawings.

[0023] As Figures 1 to 4 shown, the utility model of a threaded steel butt joint device, including base 1, in the top surface of base 1 with the center symmetry open has sliding groove 2, and each sliding groove 2 is slidably provided with the clamping assembly 3 that is fixed to the threaded steel, and is provided with the traction assembly 4 that drives the clamping assembly 3 to move on base 1. At the same time, the heating device that is provided with the threaded steel is also provided with the center position of the top surface of base 1. When the threaded steel needs to be butt jointed, two threaded steels can be fixed on two clamping assemblies 3 respectively, and the connecting end of the two threaded steels is inserted into the heating device, the connecting end of the two threaded steels is heated by the heating device, then the traction assembly 4 is started, the traction assembly 4 drives the two threaded steels to move relatively through the clamping assembly 3, so that the heated end of the two threaded steels is fused together, which saves the time of manually welding threaded steel and saves time and effort.

[0024] Specifically, the heating device includes a first support 6 provided on the base 1, an air pipe 7 is provided on the first support 6, and a plurality of spray heads 8 are communicated around the center of the inner wall of the air pipe 7, and the air pipe 7 is communicated with an external gas tank. When the threaded steel is heated, the combustible gas can be transported into the air pipe 7 through the gas tank, then the gas is sprayed from the spray head 8 of the air pipe 7, and the combustible gas is ignited, the flame is sprayed towards the threaded steel and is heated. When the threaded steel is heated, the heated ends of the two threaded steels are close to each other and are extruded, so that the two threaded steels are fused. Figure 3 As shown in the figure, the air pipe 7 is annularly arranged, and an opening is formed in the air pipe 7 for the threaded steel to pass through, which facilitates the threaded steel to separate from the air pipe 7 after fusion.

[0025] To increase the heating range of the gas pipe 7 when heating the threaded steel, a second slider 5 is slidably mounted on the base 1, a first bracket 6 is mounted on the second slider 5, and a second electric push rod 9 connected to an external power source is located on the top surface of the base 1, on one side of the second slider 5. The telescopic end of the second electric push rod 9 is connected to the second slider 5. When the nozzle 8 on the gas pipe 7 sprays flames onto the threaded steel, the second electric push rod 9 is activated. The second electric push rod 9 drives the gas pipe 7 to reciprocate on the base 1 via the second slider 5, thereby increasing the effective heating range of the gas pipe 7 on the threaded steel.

[0026] Meanwhile, to ensure rapid and uniform heating of the rebar by the air pipe 7, a sliding connection is established between the first bracket 6 and the second slider 5, and a first fixing block 10 is provided at one end of the second slider 5. A second fixing block 12 is provided on the side wall of the first bracket 6 corresponding to the first fixing block 10, and a spring 11 is provided between the first fixing block 10 and the second fixing block 12. Figure 3 As shown, a raised strip 13 is provided on the top surface of the base 1, and multiple first protrusions 14 are distributed on the side wall of the raised strip 13. A second protrusion 15 is also provided on one side of the first bracket 6. The first protrusions 14 and the second protrusions 15 cooperate with each other. When the second electric push drives the air pipe 7 on the first bracket 6 to move through the second slider 5, the second protrusion 15 on the first bracket 6 will move along the contour of the first protrusion 14 on the side wall of the raised strip 13. Under the action of the spring 11, the first bracket 6 drives the air pipe 7 to reciprocate on the second slider 5, which can improve the heating uniformity of the rebar by the air pipe 7.

[0027] like Figure 1 and Figure 2 As shown, the clamping assembly 3 for clamping and fixing threaded steel includes a first slider 31 slidably disposed in a slide groove 2, a first baffle 32 disposed at one end of the top surface of the first slider 31, and a first clamping plate 33 slidably disposed on the first slider 31. A first electric push rod 34 connected to an external power source is provided on the first slider 31, and the first electric push rod 34 is connected to the first clamping plate 33. When the clamping assembly 3 is needed to clamp and fix the threaded steel, the threaded steel can be placed between the first clamping plate 33 and the first baffle 32. Then, the first electric push rod 34 is activated, which drives the first clamping plate 33 to move towards the first baffle 32 until the threaded steel is clamped between the first clamping plate 33 and the first baffle 32. After that, the heating assembly can be activated to heat the connecting end of the threaded steel. After the threaded steel is heated, the clamping assembly 3 can be moved by the traction assembly 4.

[0028] The traction assembly 4 for moving the clamping assembly 3 specifically comprises a bidirectional threaded rod 42 rotatably arranged on the base 1, and the bidirectional threaded rod 42 is arranged along the length direction of the base 1 and penetrates through the base 1. A first motor 41 connected with an external power source is arranged at one end of the base 1, the output end of the first motor 41 is connected with the bidirectional threaded rod 42, and each first sliding block 31 in the two clamping assemblies 3 is threadedly connected with each section of threads of the bidirectional threaded rod 42. When the first sliding block 31 needs to be moved, the first motor 41 is started, the first motor 41 drives the bidirectional threaded rod 42 to rotate, and the two first sliding blocks 31 threadedly connected with the bidirectional threaded rod 42 will move relatively close to each other, so that the two clamping assemblies 3 can move relatively close to each other, and the threaded steel heating ends on the two clamping assemblies 3 can be welded at the same time. When the two clamping assemblies 3 need to move relatively far away from each other, the first motor 41 drives the bidirectional threaded rod 42 to rotate reversely.

[0029] As preferred, a second support 16 is arranged on the second sliding block 5 at the side of the heating device, and the second support 16 is provided with a cutting assembly 17 and a driving assembly 18, and the cutting assembly 17 and the driving assembly 18 are matched. The welded threaded steel is located in the cutting assembly 17, and then the driving assembly 18 drives the cutting assembly 17 to work, so that the cutting assembly 17 can cut the excess steel at the welding position, thereby improving the appearance of the threaded steel.

[0030] Specifically, the cutting assembly 17 comprises a bearing ring 171 arranged on the second support 16, a rotating ring 172 rotatably arranged on the bearing ring 171, and a cutter 173 arranged on the inner wall of the rotating ring 172. An opening is arranged on the bearing ring 171 and the rotating ring 172 for the threaded steel to pass through. When the two threaded steels are welded, the second electric push rod 9 moves the bearing ring 171 on the second support 16 to the connection position of the threaded steels through the second sliding block 5, and then the driving assembly 18 drives the rotating ring 172 to rotate, so that the cutter 173 on the inner wall of the rotating ring 172 rotates around the center of the rotating ring 172, the cutter 173 cuts the welded position of the threaded steels, and the second electric push rod 9 drives the second sliding block 5 to move, the bearing ring 171 moves through the second sliding block 5 under the action of the second support 16, so that the cutter 173 completes the cutting of the welded position of the threaded steels.

[0031] As Figure 4As shown, a plurality of tooth holes 20 are formed in the outer wall of the rotating ring 172, and a through slot 19 is formed in the outer wall of the bearing ring 171. The driving assembly 18 for driving the cutting assembly 17 to rotate comprises two second motors 181 which are symmetrically arranged at the center of the support and are connected with an external power source. A gear 182 is arranged at the output end of the second motor 181, and the gear 182 is engaged with the tooth hole 20 of the rotating ring 172. The second motor 181 drives the gear 182 to rotate, and the gear 182 is engaged with the tooth hole 20 of the rotating ring 172, so that the rotating effect of the rotating ring 172 on the bearing ring 171 can be realized, and finally the cutting work of the cutting knife 173 on the welding position of the threaded steel is realized, which is simple to operate and convenient to use. It should be noted that the two second motors 181 are controlled by a controller so that the two second motors 181 rotate at the same speed and in the same direction.

[0032] Method for using: two threaded steels to be butt-jointed are respectively placed on the two clamping assemblies 3, and the end faces of the two threaded steels are butt-jointed together, then the threaded steels are clamped and fixed by using the clamping assemblies 3, then combustible gas is sent into the gas pipe 7 by using the gas tank and ignited, so that the flame generated by the combustible gas starts to heat the butt-jointed end of the threaded steel. At the same time, the second electric push rod 9 is started to push the second sliding block 5 to move, so that each component on the second sliding block 5 starts to reciprocate, and the gas pipe 7 can also reciprocate with the second sliding block 5 through the first support 6. When the butt-jointed end of the threaded steel is heated, the traction assembly 4 is started, and the traction assembly 4 drives the two threaded steels to move relatively close through the two clamping assemblies 3, so that the two threaded steels are welded. After the threaded steels are butt-jointed, the clamping assemblies 3 release the clamping of the threaded steels, and the two clamping assemblies 3 are moved to the initial position by the traction assembly 4.
