Description

Technical Field

[0001] This invention relates to the field of metal sheet welding technology, and more specifically to a metal sheet welding apparatus. Background Technology

[0002] Sheet metal is a very common material in industry, construction, and manufacturing. There are many types of sheet metal, including aluminum, steel, titanium alloy, copper, nickel, zinc, and magnesium. Different types of sheet metal have different characteristics and uses; choosing the right material can better meet the needs of various industries.

[0003] Aluminum Plate: Aluminum plates are lightweight, corrosion-resistant, have good thermal conductivity, and are highly recyclable, making them widely used in transportation, construction, furniture, aerospace, and other fields. Steel Plate: Steel plates are a type of metal sheet with high hardness and strength, suitable for construction, manufacturing, automotive, and other fields. Titanium Alloy Plate: Titanium alloy plates are widely used in aerospace, medical equipment, and other fields due to their lightweight, high strength, corrosion resistance, and excellent high-temperature performance. Copper Plate: Copper plates have good electrical and thermal conductivity and corrosion resistance, making them widely used in electronics and electrical engineering. Nickel Plate: Nickel plates have high-temperature performance, corrosion resistance, and magnetic properties, making them widely used in manufacturing, aerospace, and other fields. Zinc Plate: Zinc plates are commonly used in construction and furniture, exhibiting good corrosion resistance and weather resistance. Magnesium Plate: Magnesium plates are lightweight, high-strength, have good corrosion resistance and processability, and are widely used in aerospace, automotive, electronics, and other fields.

[0004] When processing metal sheets, laser welding machines are required. Existing laser welding machines are usually directly exposed to the elements and lack protective mechanisms. They are easily damaged by accident, and the welding debris generated during operation can easily fly, posing a safety hazard. In addition, the welding table of existing laser welding machines is usually fixed and cannot be replaced, which limits their use.

[0005] Therefore, we propose a welding device for metal sheets. Summary of the Invention

[0006] The main objective of this invention is to provide a welding device for metal sheets. Through the cooperation of a feeding mechanism, a first welding table, and a second welding table, the device facilitates feeding operations. Furthermore, the cooperation of the first and second welding tables with the carrying platform allows for flexible replacement of either the first or second welding table on the upper surface of the carrying platform according to different processing requirements. When operating the drive mechanism, the protective components can also be moved simultaneously, fully utilizing the kinetic energy of the first motor to achieve energy conservation. Additionally, the above structure has the advantage of simple operation, thereby improving the practicality of the device and effectively solving the problems in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A welding device for metal sheets includes a base, legs, a drive mechanism, a protective component, a crossbar, a sliding sleeve, and a welding machine body. The welding machine body is mounted on top of the base. The base is a horizontally arranged rectangular plate structure. Legs are fixedly installed at the four corners of the lower end face of the base. Drive mechanisms for mounting the crossbar are provided at both ends of the upper end face of the base. The two ends of the crossbar are slidably connected to the drive mechanisms. A protective component is fitted around the outside of the welding machine body and above the drive mechanisms. The protective component is connected to the base through a support plate. A storage cavity for storing a platform is provided on the upper end face of the base. A feeding mechanism is installed on one side of the base.

[0009] The protective assembly includes a first protective cover, a second protective cover, and movable doors. The first protective cover is fitted onto the upper outer side of the second protective cover. An operating port is provided in the center of the second protective cover near the feeding mechanism. Two sets of opposite movable doors are rotatably connected to the inner walls of both ends of the operating port.

[0010] The driving mechanism includes a column, an assembly plate, a drive rod, a slide rod, a first threaded rod, and a first motor. Two sets of columns are arranged parallel to each other. Assembly plates are vertically welded to the lower parts of both ends of the columns. The assembly plates are fixedly connected to the top of the base by second bolts. The crossbar is located between the two sets of columns. A first groove for installing the first threaded rod is provided in the center of the column near the crossbar. Both ends of the crossbar are located in the first groove and are sleeved on the first threaded rod. A second groove for installing the drive rod is provided on the column away from the first groove. One end of the drive rod is fixedly connected to one end of the crossbar, and the bottom end of the drive rod is fixedly connected to one end of the upper surface of the slide rod.

[0011] The platform is a horizontally arranged rectangular plate structure. Slide rods are vertically connected to the center of both ends of the platform. The upper surface of the platform is provided with an embedding groove for installing the first welding table and the second welding table. The upper surface of the base is provided with slide rails for the slide rods to pass through. The upper surface of the first welding table is provided with a limiting member for limiting the position of the metal plate. Two sets of limiting members are arranged in parallel. The side of the first welding table near the feeding mechanism is provided with a limiting groove that matches the feeding plate.

[0012] A sliding sleeve is fitted on the crossbar, and a welding machine body capable of reciprocating back and forth is installed on one side of the sliding sleeve. The top two ends of the crossbar are provided with slots for mounting brackets. Two sets of brackets are arranged in parallel relative to each other, and both ends of the brackets are connected to the upper part of the inner walls on both sides of the second protective cover.

[0013] By adopting the above technical solution, the feeding mechanism, the first welding table, and the second welding table work together to facilitate the feeding operation of the device. Simultaneously, the cooperation between the first and second welding tables and the carrying platform allows the device to flexibly change the first or second welding table on the upper surface of the carrying platform according to different processing requirements, solving the problem of the inability to change the welding table in existing laser welding machines. The design of the protective components improves the safety of the welding device. The protective components form a relatively closed protective cavity above the base, where the metal sheet workpiece is welded, thus preventing metal sheet workpiece debris from splattering out during welding. At the same time, the protective components also protect the parts on the welding device. The outer side of the welding machine body and the top of the drive mechanism are fitted with protective components, preventing objects from directly contacting the welding device and achieving its protective purpose. When an object falls from above the welding device, it will first contact the buffer strip at the top of the first protective cover. The buffer strip can mitigate the impact force generated when the object falls, thus protecting the welding device.

[0014] Specifically, the first welding station and the second welding station are both located below the welding machine body. Slide bars are fixedly connected to the lower parts of both sides of the platform. Positioning grooves that are compatible with the slide bars are provided in the center of both sides of the storage cavity. There are two sets of slide bars and positioning grooves.

[0015] Specifically, the upper surface of the platform is provided with a slot for picking up the first welding table and the second welding table, and the four corners of the first welding table and the second welding table are fixedly connected to the upper surface of the platform by self-tapping screws.

[0016] Specifically, the column is located directly above the first slide groove and has a cavity for installing the first motor. The top end of the first threaded rod passes through the inner wall of the top end of the first slide groove and is connected to the output shaft at the bottom end of the first motor.

[0017] Specifically, the first slide groove is connected to the second slide groove, the bottom end of the first threaded rod is rotatably connected to the inner wall of the bottom end of the first slide groove, and the first threaded rod is threadedly engaged with both ends of the crossbar.

[0018] Specifically, the feeding mechanism includes a feeding plate, a mounting box, a push rod, a second motor, a movable plate, and a second threaded rod. The mounting box has a baffle on the lower part of the side near the base. The baffle is fixedly connected to the bottom end of the base by a third bolt. One side of the feeding plate is respectively engaged with one side of the first welding table and the second welding table.

[0019] Specifically, the bottom end of the second motor is fixedly connected to the inner wall of the bottom end of the mounting box, the top end of the second threaded rod is rotatably connected to the inner wall of the top end of the mounting box, the bottom end of the second threaded rod is connected to the output shaft of the top end of the second motor, the movable plate is sleeved on the second threaded rod, and a push rod is vertically inserted into the upper surface of the movable plate. The top end of the push rod passes through the mounting box and is vertically inserted into the lower surface of the feeding plate.

[0020] By adopting the above technical solution, the first motor drives the first threaded rod to rotate. Through the threaded engagement between the first threaded rod and the crossbar, the crossbar can drive the welding machine body to move downward. At the same time, the crossbar can also drive the drive rod to move downward. The drive rod pushes the slide rod downward, which can push the first welding table or the second welding table on the platform into the storage cavity in the base. Then, the metal plate workpiece on the first welding table or the second welding table can be pushed into the storage cavity, and the welding machine body welds the metal plate workpiece. When the drive rod moves downward with the crossbar, the bracket at the top of the crossbar can pull the second protective cover out from the first protective cover. The first protective cover is fastened to the top of the base, so that a relatively closed protective cavity can be formed above the base.

[0021] Specifically, the crossbar has a third groove for installing a third threaded rod on the side near the welding machine body. A moving block is fixedly connected to the inner wall of the sliding sleeve at the location of the third groove. The moving block is sleeved on the third threaded rod and threadedly engaged with the third threaded rod. A third motor is provided inside one end of the crossbar and connected to one end of the third threaded rod.

[0022] Specifically, support plates are fixedly connected to both ends of the base with first bolts. Four support plates are arranged in parallel. The top of the support plates is fixedly connected to the lower sides of the first protective cover with first bolts. Multiple buffer strips are fixedly glued to the top of the first protective cover.

[0023] The beneficial effects of this invention are:

[0024] (1) The metal plate welding device of the present invention facilitates the feeding operation of the device by means of the cooperation of the feeding mechanism, the first welding table and the second welding table. At the same time, by means of the cooperation of the first welding table, the second welding table and the carrying platform, the device can flexibly change the first welding table or the second welding table on the upper surface of the carrying platform according to different processing requirements, which solves the problem that the welding table of the laser welding machine in the prior art cannot be changed. Through the design of the protective component, the safety of the welding device can be improved. The protective component can form a relatively closed protective cavity above the base. The metal plate workpiece is welded in the protective cavity, thereby avoiding the flying of debris during the welding of the metal plate workpiece. At the same time, the protective component can also protect the parts on the welding device. The protective component is fitted on the outside of the welding machine body and the top of the drive mechanism, thereby preventing objects from directly contacting the welding device and achieving the purpose of protecting it. When an object falls from above the welding device, it will first contact the buffer strip at the top of the first protective cover. The buffer strip can mitigate the impact force generated when the object falls, further protecting the top of the welding device.

[0025] (2) The metal plate welding device of the present invention can drive the protective component to move when the driving mechanism is operated, so as to make full use of the kinetic energy of the first motor and achieve the purpose of energy saving. It also has the advantage of simple operation, thereby improving the practicality of the device.

[0026] The first motor drives the first threaded rod to rotate. Through the threaded engagement between the first threaded rod and the crossbar, the crossbar drives the welding machine body to move downward. Simultaneously, the crossbar also drives the drive rod to move downward, which in turn pushes the slide rod downward. The slide rod pushes the first or second welding table on the platform into the storage cavity inside the base, thereby pushing the metal sheet workpiece on the first or second welding table into the storage cavity. The welding machine body then welds the metal sheet workpiece. As the drive rod moves downward with the crossbar, the bracket at the top of the crossbar pulls the second protective cover out from inside the first protective cover. The second protective cover is then fastened to the top of the base, forming a relatively closed protective cavity above the base. Attached Figure Description

The crossbar 26 is located between the two sets of columns 7. The column 7 has a first groove 25 for installing the first threaded rod 24 at the center of the side near the crossbar 26. Both ends of the crossbar 26 are located in the first groove 25 and are sleeved on the first threaded rod 24. The column 7 has a second groove 30 for installing the drive rod 17 on the side away from the first groove 25. One end of the drive rod 17 is fixedly connected to one end of the crossbar 26, and the bottom end of the drive rod 17 is fixedly connected to one end of the upper surface of the slide rod 18.

[0044] The platform 20 is a horizontally arranged rectangular plate structure. Both ends of the platform 20 are vertically connected to slide rods 18. The upper surface of the platform 20 is provided with an embedding groove 21 for installing the first welding table 14 and the second welding table 19.

The side of the first welding table 14 near the feeding mechanism 9 is provided with a limiting groove 31 that matches the feeding plate 15.

[0045] A sliding sleeve 40 is fitted on the crossbar 26. A welding machine body 22 capable of reciprocating back and forth is installed on one side of the sliding sleeve 40 (the welding machine body 22 is a welding device in the prior art, and its working principle will not be described in detail here). The top ends of the crossbar 26 are provided with slots for mounting brackets 23. Two sets of brackets 23 are arranged in parallel.

A third motor is provided inside one end of the crossbar 26 and connected to one end of the third threaded rod 42.

[0048] In operation, the metal sheet workpiece to be welded is placed on the upper surface of the loading plate 15. The metal sheet workpiece is then pushed from the loading plate 15 onto the first welding table 14 or the second welding table 19 and fixed thereon, with the workpiece positioned below the welding machine body 22. Next, the first motor 39 drives the first threaded rod 24 to rotate. Through the threaded engagement between the first threaded rod 24 and the crossbar 26, the crossbar 26 drives the welding machine body 22 to move downwards. Simultaneously, the crossbar 26 also drives the drive rod 17 to move downwards, which in turn pushes the slide rod 18 downwards. The slide rod 18 then moves the first welding table 22 located on the platform 20 downwards. A welding station 14 or a second welding station 19 is pushed into the receiving cavity 27 located in the base 1, thereby pushing the metal sheet workpiece located on the first welding station 14 or the second welding station 19 into the receiving cavity 27. The welding machine body 22 welds the metal sheet workpiece. When the drive rod 17 moves downward with the crossbar 26, the bracket 23 at the top of the crossbar 26 can pull the second protective cover 6 downward from the first protective cover 5. The second protective cover 6 is fastened to the top of the base 1, so that a relatively closed protective cavity can be formed above the base 1.

Through the threaded engagement between the second threaded rod 37 and the movable plate 36, the movable plate 36 can move downward. The movable plate 36 can drive the feeding plate 15 to move downward through the push rod 33 until one side of the feeding plate 15 is engaged with one side of the first welding table 14 or the second welding table 19. The upper surface of the feeding plate 15 is on the same horizontal plane as the upper surface of the first welding table 14 or the second welding table 19.

[0054] Before use, a protective component 4 is installed on the outside of the welding machine body 22 and above the drive mechanism 3 of this metal sheet welding device. The protective component 4 is connected to the base 1 through the support plate 10. The support plate 10 is fixedly connected to both ends of the base 1 by the first bolt 11. The top of the support plate 10 is fixedly connected to the lower part of both sides of the first protective cover 5 by the first bolt 11. Multiple relatively parallel buffer strips 12 are glued to the top of the first protective cover 5. The first protective cover 5 is sleeved on the upper part of the outer side of the second protective cover 6. Two sets of relatively opposite movable doors 45 are installed in the operation port 44 in the middle of the side of the second protective cover 6 near the feeding mechanism 9. The movable doors 45 can be rotated and pulled open.

[0055] Then, according to the usage requirements, select the corresponding first welding station 14 or second welding station 19, and embed the first welding station 14 or second welding station 19 into the embedding groove 21 located on the upper end face of the platform 20. Then, fix the four corners of the first welding station 14 and second welding station 19 to the upper end face of the platform 20 with self-tapping screws. Then, install the feeding mechanism 9 on one side of the base 1. The second motor 35 drives the second threaded rod 37 to rotate. Through the threaded engagement of the second threaded rod 37 with the movable plate 36, the movable plate 36 can move downward.

The metal sheet workpiece is located below the welding machine body 22. Then, the first motor 39 drives the first threaded rod 24 to rotate. Through the threaded engagement between the first threaded rod 24 and the crossbar 26, the crossbar 26 can drive the welding machine body 22 to move downward. At the same time, the crossbar 26 can also drive the drive rod 17 to move downward. The drive rod 17 pushes the slide rod 18 downward. The slide rod 18 can push the first welding table 14 or the second welding table 19 located on the platform 20 into the storage cavity 27 located in the base 1, and thus push the metal sheet workpiece located on the first welding table 14 or the second welding table 19 into the storage cavity 27. The welding machine body 22 then welds the metal sheet workpiece.

[0057] When the drive rod 17 moves downward following the crossbar 26, the bracket 23 at the top of the crossbar 26 can pull the second protective cover 6 out from the first protective cover 5. The second protective cover 6 is fastened to the top of the base 1, so that a relatively closed protective cavity can be formed above the base 1. The metal sheet workpiece is welded in the protective cavity, which can prevent the metal sheet workpiece from splashing out during welding, thereby improving the safety of the welding device.

[0058] After the metal sheet workpiece is welded, the metal sheet workpiece located in the protective cavity can be operated or removed through the operation port 44, making the welding device convenient to use.
