A welding device for metal strip material

Abstract

This invention proposes a welding device for metal strip materials. The device includes a feeding module that inserts the first end of a new metal strip into the feeding module, a strip cutting module that automatically cuts the strip to the tail end of the previous strip, and an automatic alignment of the cut ends before welding. After welding, the strip enters a rolling and shaping module to flatten the weld seam. Following rolling, an edge trimming module removes any excess material that extends beyond the sides of the strip, improving the flatness of the weld. This invention eliminates the need for manual strip alignment, manual weld seam rolling, and manual grinding of excess material on the sides of the strip, thus improving welding efficiency, reducing downtime, saving labor time, and ultimately increasing production efficiency.

[0002] At present, TIG welding is a non-melting inert gas shielded arc welding, which uses a non-melting tungsten electrode and protects the welding area through an inert gas (usually argon) to prevent air pollution. The heat source of TIG welding is a DC arc. During welding, the workpiece is connected to the positive pole of the power supply, and the tungsten electrode in the welding torch is used as the negative pole. In the existing technology, most of the raw material welding equipment currently available on the market uses manual welding or tooling automatic welding, manual rolling of welds, and manual trimming of the side excess of the material strip. The rolling and trimming effects vary greatly, which seriously affects the welding effect, the equipment downtime is too long, and it takes up a lot of man-hours, which seriously affects production efficiency.

As the movable knife slider 95 continues to move downward, the change in the distance between the blade of the movable knife 952 and the static knife 961 realizes the cutting of the strip metal material 3, so that the front and rear ends of the strip metal material 3 are cut smoothly. As the movable knife slider 95 and the movable knife 952 continue to move downward, the cut waste is discharged from the material strip cutting module 9 through the blanking trough 932 and enters the waste collection box. Then the movable knife slider 95 drives the welding copper block 951 upward to move upward to the contact point of the bottom surface of the strip metal material 3. As the right-side feeding module 7 continues to feed, the front and rear ends of the strip metal material 3 that have been cut smoothly are in contact with each other, waiting for the next welding process.

[0047] The welding module 10 includes a welding gun 101, a Y-axis moving assembly 102, and a Z-axis moving assembly 103. The welding gun 101 moves forward and backward at the Y-axis moving assembly 102, and moves up and down at the Z-axis moving assembly 103, so as to realize the welding process between the cutting surfaces of the strip metal material with the front and rear ends cut flat at the welding copper block 951. The process of driving the welding gun to move by the Y-axis moving assembly 102 and the Z-axis moving assembly 103 in the welding module is a mature prior art and will not be described in detail here.

[0048] Combination Figure 13-14 As shown, the rolling and shaping module 12 includes a correspondingly arranged rolling wheel 1262 and a rolling support block 122. The rolling and shaping module 12 also includes a movably matched Y-axis drive assembly and a Z-axis drive assembly. The rolling wheel 1262 is fixedly arranged at the bottom of the Z-axis drive assembly. The Z-axis drive assembly drives the rolling wheel 1262 to move up and down, and the Y-axis drive assembly drives the X-axis drive assembly to move back and forth along the setting direction of the Y-axis drive assembly. The rolling and shaping module 12 also includes a rolling base plate 121, and the rolling support block 122 is fixedly arranged on the top of the rolling base plate 121.

[0049] The Y-axis driving assembly includes a rolling bracket 123 fixedly arranged on the other side of the top of the rolling base plate 121, a rolling adjustment piece 1231 is fixedly arranged on the top of the rolling bracket 123, a rolling adjustment screw 1232 is connected to the inner thread of the rolling adjustment piece 1231, a fixing frame 124 is slidingly arranged on the rolling adjustment piece 1231, the rolling adjustment screw is rotatably arranged in the fixing frame 124, a first driving motor 125 is fixedly arranged at one end of the fixing frame 124, the output shaft of the first driving motor 125 is fixedly connected to the rolling adjustment screw 1232, the rotation of the rotating shaft of the first driving motor 125 drives the rolling adjustment screw 1232 to rotate in the rolling adjustment piece 1231, since the rolling adjustment piece 1231 and the rolling bracket are fixed, the rolling adjustment screw 1232 rotates in the rolling adjustment piece 1231 and drives the fixing frame 124 to move back and forth in a straight line along the setting direction of the rolling adjustment piece 1231.

[0050] The Z-axis driving assembly includes a vertical mounting frame 126, which is fixedly arranged on the top of the fixing frame 124. The fixing frame 124 drives the vertical mounting frame 126 to move left and right during its movement. A second driving motor 127 is fixedly arranged on the upper left of the vertical mounting frame 126. A lifting plate 1261 is arranged on one side of the vertical mounting frame 126. A lifting adjustment screw 1264 is fixedly arranged on the rotating shaft of the second driving motor 127. A lifting adjustment member 1263 is threadedly connected to the surface of the lifting adjustment screw 1264. The lifting plate 1261 is fixedly connected to the lifting adjustment member 1263. The second driving motor 127 drives the lifting adjustment screw 1264 to rotate, so that the lifting adjustment member 1263 and the lifting plate 1261 fixed thereto move up and down. The moving process principle of the Y-axis driving assembly and the Z-axis driving assembly is the same, and the difference is that the directions are different. The grinding wheel 1262 is rotatably arranged at the lower end of the lifting plate 1261, and the grinding wheel 1262 is located above the rolling support block 122. The second drive motor 127 rotates to drive the lifting adjustment screw 1264 to rotate in the lifting adjustment member 1263, and drives the vertical mounting frame 126 to move back and forth in a straight line along the vertical direction. Through the above two processes, the grinding wheel 1262 is located above the rolling support block 122. The left and right and up and down movements are realized, that is, during the movement in the Y-axis and Z-axis directions, the grinding wheel 1262 rolls the raised weld to ensure that the weld thickness is consistent with the thickness of the original strip metal material.

[0051] Combination Figure 15-16The trimming module 13 shown includes a lower trimming module, an upper trimming module and a trimming drive assembly. The lower trimming module is fixedly connected to the lower cabinet, the trimming drive assembly is fixedly connected to the lower trimming module, the upper trimming module and the lower trimming module are correspondingly arranged, and the trimming drive assembly drives the upper trimming module to move up and down above the lower trimming module to cut the side edges of the weld bead of the strip metal material 3. The trimming lower die set includes a trimming bottom plate 131, a trimming drive assembly includes a trimming die frame 132, a trimming cylinder 1321 is fixedly arranged on the top of the trimming die frame 132, an upper trimming die set includes a trimming knife seat 1311, the trimming knife seat 1311 is movably arranged above the trimming bottom plate, a movable end of the trimming cylinder 1321 is fixedly connected to the trimming knife seat 1311, driving the trimming knife seat 1311 to move up and down above the trimming bottom plate 131, a discharge plate 1312 is movably arranged at the bottom of the trimming knife seat 1311, the trimming lower die set also includes a trimming lower template 1313 fixedly arranged on the trimming bottom plate 131, a trimming flow channel 1314 is fixedly arranged on the trimming lower template 1313, a trimming lower knife 13131 is fixedly arranged on the trimming lower template 1313, an trimming upper knife 13121 is fixedly arranged on the trimming knife seat 1311, and the trimming upper knife 13121 is fixedly arranged on the left and right sides of the trimming upper knife 13121. Symmetrically arranged, the bottom of the trimming upper knife 13121 passes through the unloading plate 1312 to the top of the trimming lower knife 13131, and the trimming upper knife 13121 and the trimming lower knife 13131 are arranged correspondingly. After the weld bead of the strip metal material is rolled and shaped, it enters the trimming module, and the weld bead position moves to the trimming flow channel 1314. The trimming cylinder 1321 drives the trimming knife seat 1311 and the unloading plate 1312 to move downward to the contact point between the unloading plate 1312 and the surface of the strip metal material 3. As the trimming knife seat 1311 and the unloading plate 1312 continue to move downward, the trimming upper knife 13121 contacts the trimming lower knife 13131 to achieve the cutting of the side of the weld bead of the strip metal material 3, ensuring that the width of the strip metal material at the welding point is consistent with or slightly narrower than the raw material, and ensuring that the front and rear strip metal material welding sections can smoothly pass through the tooling and fixture of the subsequent process.

[0052] In the above process, a discharge spring is arranged between the trimming knife seat 1311 and the discharge plate 1312 to buffer the discharge plate 1312, and a guide column is arranged between the trimming lower template 1313 and the trimming knife seat 1311. When the trimming cylinder 1321 drives the trimming tool holder 1311 and the unloading plate 1312 to move downward to the extreme position of the unloading plate 1312, that is, the contact point between the unloading plate 1312 and the trimming flow channel 1314, as the trimming cylinder 1321 drives the trimming tool holder 1311 and the unloading plate 1312 to continue downward, the unloading plate 1312 is in close contact with the strip metal material 3. At this time, the unloading spring is compressed (that is, the length of the trimming upper knife 13121 exposed from the bottom of the unloading plate 1312 becomes longer), and the unloading plate 1312 moves between the trimming tool holder 1311 and the trimming lower template 1313 along the direction of the guide column. A guide column is also provided between the trimming tool holder 1311 and the trimming bottom plate 131, and the process of the trimming tool holder 1311 moving up and down is carried out along the direction of the guide column. When the upper trimming knife 13121 moves downward until it contacts the lower trimming knife 13131, the side of the weld bead of the strip metal material 3 is cut. After the excess side is cut off, the strip metal material 3 is clamped in the middle by the upper trimming knives 13121 symmetrically arranged on the left and right. As the trimming knife seat 1311 moves upward, the unloading plate 1312 also moves upward to drive the upper trimming knife 13121 to move upward, and the strip metal material 3 clamped between the left and right upper trimming knives 13121 moves upward accordingly. When it moves to the point where the unloading plate 1312 no longer contacts the trimming flow channel 1314, the unloading spring resets (that is, the length of the upper trimming knife 13121 exposed from the bottom of the unloading plate 1312 becomes shorter), and the strip metal material 3 clamped between the two upper trimming knives 13121 is separated from the two upper trimming knives 13121, thereby completing the unloading process.

[0053] Combination Fig.17 The trimming lower die set also includes a cutting lower knife 1315, and the trimming upper die set also includes a cutting upper knife 1316 fixedly connected to the trimming knife seat 1311. The bottom of the cutting upper knife 1316 moves downward with the discharge plate 1312 and can pass through the discharge plate 1312 to the position above the cutting lower knife 1315. In a static state, the height of the position where the cutting edge of the cutting upper knife 1316 is located is higher than the height of the position where the cutting edge of the trimming upper knife 13121 is located (that is, the length of the bottom of the trimming upper knife 13121 passing through the discharge plate 1312 is greater than the length of the cutting upper knife 1316 passing through the discharge plate 1312). The length of the unloading plate 1312), the upper cutting knife 1316 is located. When it is necessary to cut the strip metal material 3, the upper cutting knife 1316 moves downward to contact with the lower cutting knife 1315 to cut the strip metal material 3. During this process, the movement of the upper cutting knife 1316 and its contact with the lower cutting knife 1315 to cut the strip metal material 3 are similar to the principle of the upper cutting knife 13121 moving and the upper cutting knife 13121 contacting with the lower cutting knife 13131 to trim the weld of the strip metal material 3, which will not be repeated here.

[0054] The trimming module 13 realizes cutting or trimming through a stroke switching component, which includes a cylinder 1317 and a limit switch block 1318. The cylinder 1317 includes two symmetrically arranged cylinders, one of which is fixed on the trimming bottom plate 131 and the other is fixed on one side of the trimming die frame 132. The movable ends of the two cylinders 1317 are respectively located on both sides of the trimming lower die plate 1313. The limit switch block 1318 is stepped and symmetrically and fixedly arranged at the movable ends of the cylinders 1317 on both sides. The limit switch block 1318 is driven to move synchronously through the telescopic process of the telescopic end of the cylinder 1317. The length of the cutting upper knife 1316 is shorter than the length of the trimming upper knife 13121, and a limit column 1319 is fixedly arranged on the trimming knife seat 1311. When performing trimming, the trimming tool holder 1311 moves downward until the trimming process is completed. At this time, the limit column 1319 contacts the higher part of the limit switching block 1318, assisting in the trimming process; when performing cutting, the trimming tool holder 1311 moves downward until the limit column 1319 contacts the lower part of the limit switching block 1318, assisting in the cutting process.

[0055] A waste collection box, a cutting electric cylinder and a welding main unit are installed inside the lower cabinet 1. The welding equipment uses a welding system as the main frame, integrating the conveying of strip metal materials, head and tail cutting, alignment welding, rolling and shaping, and side residual material removal. It includes a right-side feeding module 7, a right-side pressing and docking module 8, a material strip cutting module 9, a welding module 10, a left-side pressing and docking module 11, a rolling and shaping module 12, a trimming module 13, a left-side feeding module 14, a tungsten needle grinder 5 and an argon cylinder 4. An argon cylinder 4 is fixedly installed on one side of the lower cabinet 1, and a tungsten needle grinder 5 is installed on the top of the argon cylinder 4; the welding assembly, the argon cylinder 4 and the tungsten needle grinder are all prior art and will not be repeated here.

[0056] The right feeding module 7 is used as the feeding power system of the strip metal material, and cooperates with the left feeding module 14 to position and assist in positioning the strip metal material 3, ensuring the smooth switching of the processing process and the accuracy of the position. The left feeding module 14 and the right feeding module 7 have the same structure and are symmetrically arranged. The right pressing and docking module 8 cooperates with the left pressing and docking module 11 to reliably flatten the tail of the previous strip metal material 3 and the head of the next strip metal material 3, and accurately dock under the control of the servo motor module to ensure the flatness of the upper and lower surfaces of the front and rear strip metal materials 3, the uniformity of the end docking, and the straightness of the side docking. The strip cutting module 9 ensures the flat cutting of the ends of the front and rear strip metal materials 3 through the cutting electric cylinder with the cooperation of the precision knife edge. The welding module 10 controls the welding current and power through the welding host under the interpolation control of the YZ axis servo module to ensure the uniformity of the weld. The argon gas bottle 4 provides argon protection for welding to ensure the excellent welding appearance of the raw materials.

[0057] Under the control of the YZ servo module, the rolling and shaping module 12 rolls the raised weld to ensure that the weld thickness is consistent with the thickness of the original strip metal material. The trimming module 13 cuts off the side excess material of the strip metal material 3 produced after rolling the weld to ensure that the width of the strip metal material at the welding point is consistent with or slightly narrower than the raw material, ensuring that the front and rear welding sections of the strip metal material 3 can smoothly pass through the tooling and fixtures of subsequent processes.

[0058] The tungsten needle grinder 5 can grind the tungsten needle to ensure that the surface oxidation part of the welding tungsten needle is fully polished off, thereby ensuring the welding effect. The waste cut from the ends of the strip metal material 3 and the residual material cut from the side of the welding will enter the waste collection box through the guide port. When the box is full, it is manually taken out and discharged. There is no need to manually align the material strip, manually roll the weld, or manually grind the residual material on the side of the strip metal material, which improves the welding effect, reduces downtime, saves labor time, and thus improves production efficiency. The equipment is composed of a welding system as the main body, using argon as the protective gas. The welding module 10 and the tungsten needle grinder 5 are both existing technologies. The welding module is driven by a servo motor and welds at a uniform speed. The corresponding speed and welding machine parameters can be set according to the thickness of the strip metal material 3. Before welding, the right feeding module 7 is used to press the strip metal material 3 and deliver the material to the set position. Since the tungsten needle for welding is a consumable item and will oxidize after a long welding time, this equipment is equipped with a professional grinder to ensure that the shape of the tungsten needle is consistent, so that the variable factors of different welding times are close to the same. After welding is completed, the rolling and shaping module 12 automatically rolls and flattens the weld to make the thickness of the weld close to the thickness of the raw material. After rolling is completed, the trimming module 13 automatically cuts off the extended excess material after rolling to ensure that the strip metal material 3 after welding can smoothly pass the subsequent processing technology.

[0059] After the aforementioned welding, rolling and trimming are completed, the first cylinder 72 in the left and right feeding modules lifts the material strip, lifts the strip metal material 3 from the flow channel of the welding equipment, and feeds it to the subsequent process under the lifting of its internal components, thereby reducing the friction of the strip metal material in the flow channel of the welding equipment; after the aforementioned welding, rolling and trimming are completed, when the weld is unqualified, the operator can select the button to start the secondary welding function to enter the secondary welding procedure, which is specifically as follows: 1. The left and right feeding modules move the weld seam of the material strip to the cutting edge position of the trimming / cutting mold, start the trimming / cutting limit switching cylinder, switch the mold stroke limit, start the trimming / cutting oil (gas) cylinder, and cut the strip metal material 3 from the weld seam; 2. The left and right feeding modules respectively transport the front and rear material strips after cutting to the material strip cutting module 9, re-cut the front and rear material strips to make them flat, and then re-weld them according to the normal welding process. This reduces the need for manual cutting when welding is poor, further saving manual operation time.

[0060] The present invention sets left and right side feeding modules, and after the front end of the new strip metal material is inserted into the feeding module, the right side pressing and docking module 8 allows it to be aligned with the tail end of the previous strip metal material and automatically cut through the strip cutting module 9. After the cutting is completed, the cut ends of the strip metal material are automatically aligned and then welded. After the welding is completed, the rolling and shaping module 12 is entered to automatically roll the weld to make it flat. After the rolling is completed, the trimming module 13 is entered to remove the excess material that is welded / rolled beyond the side of the strip metal material, thereby improving the flatness of the welding point of the strip metal material, eliminating the need for manual alignment of the strip, manual rolling of the weld, and manual grinding of the excess material on the side of the strip metal material, thereby improving the welding effect, reducing downtime, saving labor time, and thus improving production efficiency.
