Description

Technical Field

[0001] This invention relates to the field of cable forming extrusion machine equipment technology, and more specifically, to a welding protection device and method for cable forming extrusion machine equipment. Background Technology

[0002] Cable forming extrusion equipment refers to specialized electromechanical equipment used in the cable production process to uniformly wrap the insulation layer and sheath layer of the cable onto the cable core through an extrusion process. This equipment typically has functions such as high-precision temperature control, pressure regulation, and stable extrusion speed to ensure that the quality and performance of the cable products meet the standard requirements. In the manufacturing process of cable forming extrusion equipment, the welding process is a crucial step, which directly affects the structural strength and stability of the equipment. The welding protection device and method for cable forming extrusion equipment involved in this invention is an innovative solution proposed for this step.

[0003] According to patent document CN117943764B, an extruder barrel processing device is disclosed, including a chamber. The upper end of the chamber is open, the bottom is inclined, and an outlet is provided at a low position at the bottom of the chamber. An adjusting plate assembly is provided at the lower end of the chamber, which can control the output of workpieces from the chamber. A welding assembly and a support clamping assembly are provided on the side of the chamber. The present invention uses an adjusting plate assembly to control the output of tubes in groups from the chamber 1, so that tubes that can be welded into the same extruder barrel are supported on the support clamping assembly, and the position of the tubes is restricted by the support clamping assembly. Under the operation of the welding assembly, multiple tubes are welded to form an extruder barrel, realizing non-manual transfer of tubes and extruder barrels, as well as continuous processing of extruder barrels, reducing the labor intensity of workers, and correspondingly improving the welding efficiency of extruder barrels.

[0004] When operating a cable forming extruder, the cable to be processed is usually slowly inserted into the extruder through a specific inlet. During this process, the equipment heats the cable material evenly to a suitable processing temperature. Then, the heated cable is smoothly pulled out from the extruder outlet by mechanical traction. In this way, the cable is gradually formed into a complete cable product with an insulation layer under the action of the extruder. In the extruder manufacturing process, the installation of the extrusion port is particularly critical. Usually, technicians will pre-connect a specific area of ​​the extrusion port to the extruder body with bolts and nuts to ensure its stability. Then, in order to prevent material leakage, any gaps in the extrusion port need to be welded and sealed. However, traditional welding methods often reveal many shortcomings in practical applications. For example, spatter that may be generated during welding can easily cause varying degrees of damage to the area around the extrusion nozzle. This not only affects the appearance of the extruder but also poses a potential threat to its overall quality and service life. In addition, due to the lack of effective protective measures during operation, the high-temperature welding environment may cause burns and other safety hazards to on-site operators, and in severe cases, may even lead to safety accidents that threaten the lives of personnel. Therefore, improving the welding process and enhancing the safety and reliability of the equipment has become an urgent problem to be solved in the field of cable forming extruder equipment manufacturing. Summary of the Invention

[0013] As a further aspect of the present invention: Rotary uprights are rotatably connected to the outer middle of the two columnar rotating crossbar sleeves; columnar abutments are fixedly connected to the outer tops of the two rotating uprights; rotating upright grooves are provided on the outer sides of the two rotating uprights; lifting blocks are slidably connected to the inner walls of the rotating upright grooves on the outer sides of the two rotating uprights; rotating pull rods are rotatably connected to the outer sides of the two lifting blocks; the rear inner sides of the two rotating pull rods are rotatably connected to the tops of the outer sides of the two outer turntables; the two rotating uprights... A columnar push-pull crossbar is fixedly connected to the bottom inner side of the rod. A movable rod is slidably connected to the outer wall of the columnar push-pull crossbar. An elliptical groove is opened in the middle of the movable rod. The outer wall of the columnar push-pull crossbar is slidably connected to the inner wall of the elliptical groove opened in the movable rod. A triangular abutment is fixedly connected to the front side of the movable rod. The front sides of the left and right sides of the triangular abutment are in contact with the inner sides of the outer walls of the two rotating wheels. A welding robotic arm connecting table is fixedly connected to the top of the movable rod. A laser welding robotic arm is fixedly connected to the top of the welding robotic arm connecting table.

[0014] As a further embodiment of the present invention: the movable platform includes a convex push-pull plate, a device placement plate is fixedly connected to the middle of the front side of the convex push-pull plate, and horizontal L-shaped push-pull side plates are fixedly connected to the left and right sides of the bottom of the convex push-pull plate. The outer walls of the two horizontal L-shaped push-pull side plates are slidably connected to the inner walls of the two concave plates and the two concave blocks. The rear side of the two horizontal L-shaped push-pull side plates away from the convex push-pull plate is in contact with the outer walls of the two columnar abutments.

[0015] In addition, the present invention also relates to a welding protection device and method for cable forming extrusion machine equipment, comprising the following steps: Step 1: The operator places the cable forming extrusion equipment to be welded stably on the designated position on the top of the equipment placement plate and checks whether the equipment placement is stable to ensure that there is no risk of relative sliding between the equipment and the equipment placement plate; Step 2: Start the motor through the control panel. The motor output drives the transmission disc to rotate, and the transmission disc drives the second transmission disc to rotate synchronously through the track, thereby causing the columnar rotating crossbar to start rotating. Step 3: When the columnar rotating crossbar rotates, the outer turntable rotates accordingly. The outer turntable drives the lifting block to slide within the guide structure through the rotating pull rod. During the sliding process, the lifting block drives the columnar abutment to move back and forth through the rotating upright. Step 4: The columnar push rod pushes the horizontal L-shaped push-pull side plate to slide on the inner wall of the concave plate and concave block, causing the entire moving platform to move backward. At the same time, the columnar push-pull horizontal rod rotates, causing the moving rod to move backward. Step 5: As the moving rod moves backward, the triangular stop block moves along with it, and its inclined surface gradually approaches the trigger wheel at the bottom of the inverted L-shaped expansion and contraction baffle. When it makes contact, it squeezes the trigger wheel. Step Six: After the trigger wheel is squeezed, it drives the two expansion and contraction blocks to slide relative to each other in the expansion and contraction block slide plate. The arc-shaped rotating rod rotates with the hinge block as the fulcrum. Through the bidirectional hinge block and the hinge rod, the expansion and contraction base plate moves inward along the columnar guide bar. Step 7: The inverted L-shaped expansion and contraction baffle moves inward and closes synchronously with the expansion and contraction base plate as the slider of the inverted L-shaped expansion and contraction baffle and the top guide plate cooperate, forming a protective space on both sides of the welding frame. Step 8: When the equipment placement plate is completely moved inside the two inverted L-shaped expansion and contraction baffles, and the laser welding robotic arm reaches the welding position, the inverted L-shaped expansion and contraction baffles are just closed, and the rubber limiting pads are tightly attached to the equipment. The laser welding robotic arm is then started to perform welding operations on the cable forming extrusion equipment. During the welding process, the inverted L-shaped expansion and contraction baffles effectively block sparks and spatter, protecting the equipment and the surrounding environment.

[0016] The beneficial effects of this invention are as follows: This invention, by incorporating a welding frame and a control frame, achieves highly automated and precise positioning technology, along with comprehensive protective measures, during the welding process of cable forming extrusion equipment. Firstly, through a precision motor drive and the coordinated operation of a series of transmission components, precise control of the equipment placement plate's movement is achieved. This control process ensures the placement plate moves accurately to the predetermined position, laying a solid foundation for subsequent welding work. Simultaneously, a robotic arm approaches the welding point, ensuring the accuracy of the welding position. During the welding process, an inverted L-shaped expansion and contraction baffle design automatically closes, forming a closed protective space. This protective space effectively blocks sparks and spatter generated during welding, preventing damage to the equipment itself and the surrounding environment. This comprehensive protective measure greatly improves the safety of welding operations and also protects the personal safety of operators. Attached Figure Description

The control component 21 includes a motor connecting plate 211. The rear side of the bottom of the motor connecting plate 211 is fixedly connected to the top of the right side connecting plate 114. A motor 212 is fixedly connected to the front side of the top of the motor connecting plate 211. A transmission disc 213 is fixedly connected to the output end of the motor 212. A track 214 is fitted on the outer wall of the transmission disc 213. A second transmission disc 215 is fitted on the rear side of the inner wall of the track 214. A columnar rotating crossbar 216 is fixedly connected to the inner wall of the second transmission disc 215. Columnar rotating crossbar sleeves 218 are fitted on both the left and right sides of the outer wall of the columnar rotating crossbar 216. The rear sides of the columnar rotating crossbar sleeve 218 are fixedly connected to the inner top of the two front upright plates 111. The left and right ends of the two columnar rotating crossbars 216 extend to the outer sides of the two columnar rotating crossbar sleeves 218 and are fixedly connected to outer turntables 217. Rotating uprights 219 are rotatably connected to the middle of the outer sides of the two columnar rotating crossbar sleeves 218. Columnar abutments 2112 are fixedly connected to the top of the outer sides of the two rotating uprights 219. Rotating upright grooves 2111 are provided on the outer sides of the two rotating uprights 219. Lifting blocks 2113 are slidably connected to the inner walls of the rotating upright grooves 2111 on the outer sides of the two rotating uprights 219. The outer sides of the two lifting blocks 2113... Each side is rotatably connected to a rotating pull rod 2114. The rear inner sides of both rotating pull rods 2114 are rotatably connected to the top of the outer side of the two outer turntables 217. The bottom inner side of the two rotating uprights 219 is fixedly connected to a columnar push-pull crossbar 2110. The outer wall of the columnar push-pull crossbar 2110 is slidably connected to a moving rod 2115. An elliptical groove 2116 is opened in the middle of the moving rod 2115. The outer wall of the columnar push-pull crossbar 2110 is slidably connected to the inner wall of the elliptical groove 2116 opened in the moving rod 2115. A triangular abutment 2117 is fixedly connected to the front side of the moving rod 2115. The front sides of the left and right sides of the triangular abutment 2117 are in contact with the inner side of the outer wall of the two rotating wheels 1211. The top of the moving rod 2115 is fixedly connected to a welding robotic arm connecting table 2118, and the top of the welding robotic arm connecting table 2118 is fixedly connected to a laser welding robotic arm 2119. The moving table 22 includes a convex push-pull plate 221. The middle of the front side of the convex push-pull plate 221 is fixedly connected to an equipment placement plate 222. The left and right sides of the bottom of the convex push-pull plate 221 are fixedly connected to horizontal L-shaped push-pull side plates 223. The outer walls of the two horizontal L-shaped push-pull side plates 223 are slidably connected to the inner walls of the two concave plates 1110 and the two concave blocks 1112. The rear side of the two horizontal L-shaped push-pull side plates 223 away from the convex push-pull plate 221 is in contact with the outer wall of the two columnar abutments 2112. When welding is required on the cable forming extrusion equipment, the equipment is first placed on top of the equipment placement plate 222. Then, the motor 212 is started. After the motor 212 starts, its output end drives the transmission disc 213 to rotate. Since the transmission disc 213 is tightly fitted with the track 214, the track 214 also starts to drive. The second transmission disc 215 is fitted on the rear side of the inner wall of the track 214. Driven by the track 214, the second transmission disc 215 starts to rotate, which causes the columnar rotating crossbar 216 fixedly connected to its inner wall to rotate together. When the columnar rotating crossbar 216 rotates, the columnar rotating crossbar sleeves 218 on its left and right sides provide support and stability. The outer turntables 217, which extend to the outside of the sleeves and are fixedly connected at both ends of the columnar rotating crossbar 216, also rotate. The rotation of the outer turntables 217 drives the rotating pull rod 2114, which is rotatably connected to the top of its outer side, to move. The other end of the rotating pull rod 2114 is rotatably connected to the lifting block 2113, so the lifting block 2113 slides in the rotating upright slide groove 2111. The sliding of the lifting block 2113 causes the rotating upright 219 to rotate, and the columnar abutment 2112 fixedly connected to the top of the outer side of the rotating upright 219 also moves back and forth. The outer wall of the columnar abutment 2112 is in contact with the rear side of the horizontal L-shaped push-pull side plate 223. Therefore, when the columnar abutment 2112 moves, it will push the horizontal L-shaped push-pull side plate 223 to slide on the inner wall of the concave plate 1110 and the concave block 1112, thereby driving the entire moving platform 22 to move backward toward the top inner side of the welding frame 1. At the same time, the columnar push-pull crossbar 2110, which is fixedly connected to the bottom of the inner side of the rotating upright 219, is also rotating. Its outer wall is slidably connected to the inner wall of the elliptical groove 2116 opened by the moving rod 2115, so it will drive the moving rod 2115 to move backward. The triangular abutment 2117 fixedly connected to the moving rod 2115 moves along with it. The welding robotic arm connecting table 2118, which is fixedly connected to the top of the moving rod 2115, moves with the movement of the moving rod 2115, thereby driving the laser welding robotic arm 2119 closer to the welding frame 1.

[0022] like Figure 3-6As shown, the welding frame 1 includes a connecting frame 11. Protective components 12 are provided on both the left and right sides of the inner side of the connecting frame 11. The connecting frame 11 includes two sets of upright plates 111. Guide horizontal plates 112 are fixedly connected to the top of both the front and rear sets of upright plates 111. Support plates 113 are fixedly connected to the front sides of the two front upright plates 111. Side connecting plates 114 are fixedly connected to the middle of the outer sides of both sets of support plates 113. Expanding block sliding plates 118 are fixedly connected to the middle of the top of both side connecting plates 114. Vertical connecting side plates 1113 are fixedly connected to the left and right sides of the top of the two guide horizontal plates 112. Top guide plates 119 are fixedly connected to the top of both the front and rear sets of vertical connecting side plates 1113. The top of the inner side of both the front and rear sets of vertical connecting side plates 1113... Each of the two guide plates 112 is fixedly connected to a columnar guide crossbar 115 at the bottom. Longitudinal connecting plates 116 are fixedly connected to the left and right sides of the inner sides of the two guide crossbars 112. Hinges 117 are fixedly connected to the inner sides of the two longitudinal connecting plates 116. Concave plates 1110 are fixedly connected to the left and right sides of the top of the two top guide plates 119. L-shaped connecting plates 1111 are fixedly connected to the middle of the rear side of the two rear vertical connecting side plates 1113. Concave blocks 1112 are fixedly connected to the rear side of the top of the two L-shaped connecting plates 1111. The front sides of the two concave blocks 1112 are aligned with the rear sides of the two concave plates 1110. Both protective components 12 include inverted L-shaped expansion and contraction baffles 121. The middle of the inner sides of the two inverted L-shaped expansion and contraction baffles 121 are fixedly connected to the central part of their respective sides. A rubber limiting pad 122 is fixedly connected to each of the two inverted L-shaped expansion and contraction baffles 121. A horizontal L-shaped connecting plate 123 is fixedly connected to the inner side of each of the two horizontal L-shaped connecting plates 123. An expansion and contraction base plate 125 is fixedly connected to the bottom of each of the two inverted L-shaped expansion and contraction baffles 121. Inverted L-shaped expansion and contraction baffle sliders 124 are fixedly connected to the front and rear sides of the bottom of each of the two inverted L-shaped expansion and contraction baffles 121. The outer walls of the left and right sets of inverted L-shaped expansion and contraction baffle sliders 124 are slidably connected to the left and right sides of the inner walls of the two top guide plates 119. An expansion and contraction base plate 125 is fixedly connected to the bottom of each of the two horizontal L-shaped connecting plates 123. The top and bottom inner walls of the front and rear sides of the two expansion and contraction base plates 125 are slidably connected to the left and right sides of the outer walls of the front and rear sets of columnar guide crossbars 115. The outer sides of the two expansion and contraction base plates 125 are... Each part is rotatably connected to a hinge rod 126. The outer wall of each hinge rod 126 away from the expansion base plate 125 is rotatably connected to a bidirectional hinge block 127. The inner wall of each bidirectional hinge block 127 away from the hinge rod 126 is rotatably connected to an arc-shaped rotating rod 128. The middle of the outer wall of each arc-shaped rotating rod 128 is rotatably connected to the inner wall of each hinge block 117. The bottom of the inner side of each arc-shaped rotating rod 128 is fixedly connected to a diagonal tie rod 129. The side of each diagonal tie rod 129 that is close to each other is rotatably connected to an expansion cross block 1210. The inner side of each expansion cross block 1210 is rotatably connected to a rotating wheel 1211. The outer wall of each expansion cross block 1210 is slidably connected to the inner wall of each expansion block slide plate 118. When motor 212 starts, causing the triangular abutment 2117 to move rearward, and the equipment placement plate 222 to move towards the inside of the two inverted L-shaped expansion and contraction baffles 121, and the welding robotic arm connecting table 2118 drives the top laser welding robotic arm 2119 to move towards the welding frame 1, the inclined surface of the triangular abutment 2117 will contact the trigger wheel 1211 set at the bottom of the inverted L-shaped expansion and contraction baffle 121 during the movement of the triangular abutment 2117. Due to the continuous rearward movement of the triangular abutment 2117, the trigger wheel 1211 is squeezed and drives the two expansion and contraction horizontal blocks 1210 to move in the expansion and contraction block slide plate 118. For sliding, this sliding action further causes the two arc-shaped rotating rods 128 to rotate around the hinge block 117 as the fulcrum. As the arc-shaped rotating rods 128 rotate, they transmit force to the retractable base plate 125 through the bidirectional hinge block 127 and the hinge rod 126, causing the retractable base plate 125 to move inward along the columnar guide bar 115. At the same time, the inverted L-shaped retractable baffle 121, with the cooperation of the inverted L-shaped retractable baffle slider 124 and the top guide plate 119, also moves inward and closes synchronously with the unfolding of the retractable base plate 125, thereby forming a gradually expanding protective space on both sides of the welding frame 1. When the equipment placement plate 222 is completely moved inside the two inverted L-shaped expansion and contraction baffles 121, and the laser welding robotic arm 2119 accurately reaches the welding position, the two inverted L-shaped expansion and contraction baffles 121 are also closed. At this time, the rubber limiting pad 122 is tightly attached to the cable forming extrusion device on the equipment placement plate 222, which plays a role in stabilizing the equipment. The two inverted L-shaped expansion and contraction baffles 121 effectively prevent the sparks and spatter generated during the welding process from damaging the equipment and the surrounding environment.

[0023] In addition, the present invention also relates to a welding protection device and method for cable forming extrusion machine equipment, comprising the following steps: Step 1: The operator places the cable forming extrusion equipment to be welded stably on the designated position on the top of the equipment placement plate 222, and checks whether the equipment placement is stable to ensure that there is no risk of relative sliding between the equipment and the equipment placement plate 222; Step 2: Start motor 212 via control panel. The output of motor 212 drives transmission disc 213 to rotate. Transmission disc 213 drives second transmission disc 215 to rotate synchronously via track 214, thereby causing columnar rotating crossbar 216 to start rotating. Step 3: When the columnar rotating crossbar 216 rotates, the outer turntable 217 rotates accordingly. The outer turntable 217 drives the lifting block 2113 to slide within the guide structure by rotating the pull rod 2114. During the sliding process, the lifting block 2113 drives the columnar abutment 2112 to move back and forth by rotating the upright rod 219. Step 4: The columnar push rod 2112 pushes the horizontal L-shaped push-pull side plate 223 to slide on the inner wall of the concave plate 1110 and the concave block 1112, so that the moving platform 22 moves backward as a whole. At the same time, the columnar push-pull horizontal rod 2110 rotates and drives the moving rod 2115 to move backward. Step 5: When the moving rod 2115 moves backward, the triangular block 2117 moves along with it, and its inclined surface gradually approaches the trigger wheel 1211 at the bottom of the inverted L-shaped expansion and contraction baffle 121. When it contacts, it squeezes the trigger wheel 1211. Step 6: After the trigger wheel 1211 is squeezed, it drives the two expansion and contraction blocks 1210 to slide relative to each other in the expansion and contraction block slide plate 118. The arc-shaped rotating rod 128 rotates with the hinge block 117 as the fulcrum. Through the bidirectional hinge block 127 and the hinge rod 126, the expansion and contraction base plate 125 moves inward along the columnar guide bar 115. Step 7: The inverted L-shaped expansion and contraction baffle 121, in cooperation with the inverted L-shaped expansion and contraction baffle slider 124 and the top guide plate 119, moves inward and closes synchronously with the expansion and contraction base plate 125 as it unfolds, forming a protective space on both sides of the welding frame 1. Step 8: When the equipment placement plate 222 is completely moved to the inside of the two inverted L-shaped expansion and contraction baffles 121, and the laser welding robotic arm 2119 reaches the welding position, the inverted L-shaped expansion and contraction baffles 121 are just closed, and the rubber limiting pads 122 are tightly attached to the equipment. The laser welding robotic arm 2119 is started to perform welding operations on the cable forming extrusion equipment. During the welding process, the inverted L-shaped expansion and contraction baffles 121 effectively block sparks and spatter, protecting the equipment and the surrounding environment.

[0024] Working principle of this invention: When welding is required on the cable forming extrusion equipment, the equipment is first placed on top of the equipment placement plate 222. Then, the motor 212 is started. After the motor 212 starts, its output end drives the transmission disc 213 to rotate. Since the transmission disc 213 is tightly fitted with the track 214, the track 214 also starts to drive. The second transmission disc 215 is fitted on the rear side of the inner wall of the track 214. Driven by the track 214, the second transmission disc 215 starts to rotate, which in turn causes the columnar rotating crossbar 216, which is fixedly connected to its inner wall, to rotate together. The columnar rotating crossbar 216 drives the outer turntable 217 to rotate as well. The rotation of the outer turntable 217 drives the rotating pull rod 2114, which is rotatably connected to its outer top, to move. The sliding of the lifting block 2113 causes the rotating upright 219 to rotate, which in turn causes the columnar abutment 2112 to move back and forth. When the columnar abutment 2112 moves, it pushes the horizontal L-shaped push-pull side plate 223 to slide on the inner wall of the concave plate 1110 and the concave block 1112, thereby causing the entire moving platform 22 to move backward toward the top inner side of the welding frame 1. At the same time, the columnar push-pull horizontal bar 2110, which is fixedly connected to the bottom inner side of the rotating upright 219, also rotates, causing the moving rod 2115 to move backward. The triangular abutment 2117, which is fixedly connected to the moving rod 2115, moves along with it. The welding robot arm connecting platform 2118, which is fixedly connected to the top of the moving rod 2115, moves with the moving rod 2115, and thus... As the laser welding robotic arm 2119 moves closer to the welding frame 1, the motor 212 starts, causing the triangular abutment 2117 to move backward. The equipment placement plate 222 moves towards the inside of the two inverted L-shaped expansion and contraction baffles 121. When the welding robotic arm connecting table 2118 moves the top laser welding robotic arm 2119 towards the welding frame 1, the triangular abutment 2117 moves. During this movement, its inclined surface contacts the trigger wheel 1211 located at the bottom of the inverted L-shaped expansion and contraction baffle 121. Due to the continuous backward movement of the triangular abutment 2117, the trigger wheel 1211 is compressed, causing the two expansion and contraction blocks 1210 to slide relative to each other within the expansion and contraction block slide plate 118. This sliding action further causes the two arc-shaped rotating rods 128 to... Rotating around hinge block 117, the arc-shaped rotating rod 128 transmits force to the retractable base plate 125 via bidirectional hinge block 127 and hinge rod 126, causing the retractable base plate 125 to move inward along the columnar guide bar 115. Simultaneously, the inverted L-shaped retractable baffle 121, in cooperation with the inverted L-shaped retractable baffle slider 124 and the top guide plate 119, also moves inward and closes synchronously with the unfolding of the retractable base plate 125, thus forming a gradually expanding protective space on both sides of the welding frame 1. When the equipment placement plate 222 is completely moved inside the two inverted L-shaped retractable baffles 121, and the laser welding robotic arm 2119 accurately reaches the welding position, the two inverted L-shaped retractable baffles 121 also close precisely.At this time, the rubber limiting pad 122 is in close contact with the cable forming extrusion equipment on the equipment placement plate 222, which stabilizes the equipment. The two inverted L-shaped expansion and contraction baffles 121 effectively prevent sparks and spatter generated during welding from damaging the equipment and the surrounding environment.
