Description

Technical Field

[0001] This invention relates to the field of electrode and core welding technology, and in particular to an integrated electrode and core welding production line and its manufacturing process. Background Technology

[0002] Traditional welding electrode core production is completed through two production lines: a wire drawing production line and a core cutting production line. The wire drawing production line involves: coiled steel bars being drawn to the required wire diameter via a wire feeding machine and a wire drawing machine; then, a reel take-up machine or a basket take-up machine collects the wire onto the reel or basket. The core cutting production line involves: a reel wire feeding machine or basket wire feeding machine, a traction and straightening process, a fixed-length cutting process, and finally, material collection.

[0003] Research revealed the following shortcomings in the production of this traditional welding electrode core:

[0004] The production of the welding core is divided into two lines. Both of these production lines occupy a relatively large area, have a long production process, and are inefficient.

[0005] Having two lines increases the cost of the additional take-up and pay-off machines.

[0006] It involves many operators, numerous turnover steps, and is time-consuming and labor-intensive.

[0007] Therefore, there is an urgent need for an integrated production line for welding electrodes and cores, along with its production process, to meet the market demand for welding electrodes and cores. Summary of the Invention

[0008] Based on the technical problems of large footprint, high equipment cost and complicated operation caused by the two production lines mentioned in the background art, the present invention proposes an integrated production line for welding rods and cores and its production process.

[0009] This invention proposes an integrated production line for welding rods and core wires, comprising an upper-pull wire feeding machine, a straight-feed wire drawing machine, and a processing table. The upper-pull wire feeding machine is located on one side of the straight-feed wire drawing machine. The processing table is characterized by having a traction device installed on one side of the straight-feed wire drawing machine, a straightening system installed on one side of the traction device, a welding rod flying shear machine on one side of the processing table, a welding rod wire feeder installed on one side of the welding rod flying shear machine, and a welding rod collector installed on one side of the welding rod wire feeder for collecting the cut welding core wires.

[0010] Preferably, a motor is provided on one outer wall of the traction device, and a drive roller is installed at one end of the motor output shaft. Adjustment grooves are provided on both outer walls of the traction device. Threaded rods are connected to the inner walls of the two adjustment grooves via bearings. Mounting blocks are provided on the outer walls of the two threaded rods. The same driven roller is connected to the outer walls of the two mounting blocks on opposite sides via bearings. The drive roller and the driven roller are located on the same vertical plane, and traction grooves are provided on the outer walls of both the drive roller and the driven roller. Anti-slip patterns are evenly distributed on the inner walls of the traction grooves.

[0011] Preferably, the outer wall of the traction device is provided with an inlet connector, and a locking plate is connected to the outer wall of the inlet connector by a hinge. The outer wall of the locking plate is provided with equidistant teeth, and the inclination direction of the teeth is from the inlet connector to the traction device. The outer wall of the locking plate near the traction device is provided with equidistant return springs, and the return springs are connected to the inner circumferential wall of the inlet connector.

[0012] Preferably, a pad is installed on the bottom outer wall of the traction device, a top cover is provided on the top outer wall of the traction device, an installation groove is provided on the inner wall of the top cover, a through hole is provided on one side of the top outer wall of the top cover, an adjusting plate is inserted into the inner wall of the through hole, an outlet hole is provided on one side outer wall of the adjusting plate, a pull ring is provided on the top outer wall of the adjusting plate, a through slit is provided on one side outer wall of the traction device, and the adjusting plate is located on the inner wall of the through slit.

[0013] Preferably, each of the two threaded rods has a drive shaft at its top end, and the same drive belt is fitted onto the outer wall of the two drive shafts. The drive belt is located inside the mounting groove, and a knob is installed at the top end of one drive shaft.

[0014] A manufacturing process for an integrated welding electrode and core production line includes the following steps:

[0015] S1: First, the treated welding rod raw wire (φ6.5-φ5.5) is fed into the straight wire drawing machine through the top-drawing wire feeding machine to draw the welding rod raw wire to the diameter (φ2-φ5) required for the welding core.

[0016] S2: Then, driven by the motor, it enters the traction device. Turning the knob in the traction device can adjust the distance between the active roller and the driven roller, which is convenient for receiving welding core wires of various diameters. The locking plate in the guide joint is used to lock the welding core wire after it is cut.

[0017] S3: After being pulled, it enters the straightening system, which straightens the welding core wire;

[0018] S4: After straightening, the welding core wire enters the welding rod flying shear machine. The flying shear speed is achieved by the encoder and control system installed at the rear of the traction wheel to cut the welding core wire to a fixed length.

[0019] S5: The cut welding core enters the electrode feeder, and then enters the electrode collector to complete the entire electrode core production process.

[0020] The beneficial effects of this invention are as follows:

[0021] This integrated electrode and core welding production line combines two traditional production lines into one by selecting and assembling a top-pull wire feeding machine and a straight-line wire drawing machine within the appropriate range. The traction device is then installed on one side of the straight-line wire drawing machine, along with a straightening system, a welding electrode flying shear, a welding electrode feeder, and a welding electrode collector. The traction device is a flexible and adjustable mechanism, which better connects the straight-line wire drawing machine to the subsequent straightening system, improving traction smoothness. The combined production line eliminates the need for wire take-up and subsequent wire feeding, reducing production line costs. From wire feeding to the finished core welding product, there is no need for intermediate handling or manual intervention; the reduced take-up, feeding, and handling steps significantly decrease the production line's footprint.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0036] Reference Figure 1-6 An integrated production line for welding rods and core wires includes an upper-pull wire feeding machine 1, a straight-feed wire drawing machine 2, and a processing table. The upper-pull wire feeding machine 1 is located on one side of the straight-feed wire drawing machine 2. The processing table is characterized by having a traction device 3 installed on one side of the straight-feed wire drawing machine 2, a straightening system 4 installed on one side of the traction device 3, a welding rod flying shear 5 installed on the processing table, and a welding rod wire feeder 6 installed on one side of the welding rod flying shear 5. A welding rod collector 7 is also installed on one side of the welding rod wire feeder 6, and the welding rod collector 7 is used to collect the cut welding core wires.

[0037] Reference Figure 2 and Figure 3 In this invention, a motor 13 is provided on one side of the outer wall of the traction device 3. A drive roller 17 is installed at one end of the output shaft of the motor 13. Adjustment grooves are provided on both sides of the outer wall of the traction device 3. Threaded rods 14 are connected to the inner walls of the two adjustment grooves through bearings. Mounting blocks are provided on the outer walls of the two threaded rods 14. The same driven roller 19 is connected to the outer wall of the two mounting blocks on opposite sides through bearings. The drive roller 17 and the driven roller 19 are located on the same vertical plane. Traction grooves are provided on the outer walls of both the drive roller 17 and the driven roller 19. Anti-slip textures 18 are provided at equal intervals on the inner walls of the traction grooves to provide the friction required for traction.

[0038] Reference Figure 2 and Figure 5 In this invention, an inlet connector 11 is provided on one side of the outer wall of the traction device 3. Locking plates 22 are connected at equal intervals on one side of the outer wall of the inlet connector 11 by hinges. Each locking plate 22 has equidistant tooth marks 24 on one side of its outer wall, and the inclination direction of the tooth marks 24 is from the inlet connector 11 to the traction device 3. Each locking plate 22 has equidistant return springs 23 on one side of its outer wall near the traction device 3. Each return spring 23 is connected to the inner circumferential wall of the inlet connector 11.

[0039] Reference Figure 2 , Figure 3 and Figure 4In this invention, a pad 12 is installed on the bottom outer wall of the traction device 3, a top cover 10 is provided on the top outer wall of the traction device 3, and an installation groove 20 is provided on the inner wall of the top cover 10. The top ends of the two threaded rods 14 are provided with drive shafts, and the same drive belt 21 is sleeved on the outer wall of the two drive shafts. The drive belt 21 is located inside the installation groove 20. A knob 9 is installed on the top end of one drive shaft. A through hole is provided on one side of the top outer wall of the top cover 10, and an adjusting plate 15 is inserted into the inner wall of the through hole. An outlet hole 16 is provided on one side outer wall of the adjusting plate 15, and a pull ring 8 is provided on the top outer wall of the adjusting plate 15. A through slot is provided on one side outer wall of the traction device 3, and the adjusting plate 15 is located on the inner wall of the through slot. The height of the adjusting plate 15 can be changed by the pull ring 8, thereby adjusting the lateral position of the outlet hole 16, which makes it easier to adapt to the straightening system 4.

[0040] In summary, during the operation of the entire production line, the traction device 3 pulls out the welding core wire from the straight-feed wire drawing machine 2 and guides it to the straightening system 4. In this process, before the motor 13 drives the active roller 17 to rotate, the knob 9 is turned first to make the two threaded rods 14 rotate. At the same time as the two threaded rods 14 rotate, the two mounting blocks move downward, thereby driving the driven roller 19 to move downward and closer to adapt to the diameter of the welding core wire. Utilizing the friction of the anti-slip texture 18 in the traction groove provided on the outer wall of the active roller 17 and the driven roller 19, the welding core wire is gradually pulled out. At the same time, the locking plate 22 provided in the inlet connector 11 is squeezed by the return spring 23, and the relative inner sides of the locking plate 22 are provided with tooth marks 24. The inclination direction of the tooth marks 24 points from the inlet connector 11 to the traction device 3, which can effectively prevent the welding core wire from pulling back.

[0041] A production process for an integrated welding electrode and welding core production line includes the following steps:

[0042] S1: First, the treated welding rod raw wire (φ6.5-φ5.5) is fed into the straight wire drawing machine through the top drawing machine 1 to draw the welding rod raw wire to the diameter (φ2-φ5) required for the welding core.

[0043] S2: Then, driven by the motor 13, it enters the traction device 3. In the traction device 3, rotating the knob 9 can adjust the distance between the active roller 17 and the driven roller 19, which is convenient for receiving welding core wires of various diameters. The subsequent cut welding core wire is locked by the locking plate 22 in the guide joint 11.

[0044] S3: After being pulled, it enters the straightening system 4, and the straightening system 4 straightens the welding core wire;

[0045] S4: After straightening, the welding core wire enters the welding rod flying shear machine 5. The flying shear speed is achieved by the encoder and control system installed at the rear of the traction wheel to cut the welding core to a fixed length.

[0046] S5: The cut welding core enters the electrode feeder 6, and then enters the electrode collector 7 to complete the entire electrode core production process.
