Description

TECHNICAL FIELD

[0001] The application belongs to the field of ferrous metal material processing equipment, in particular to a ferrous metal smelting and rolling product welding equipment. BACKGROUND

[0002] The ferrous metal smelting and rolling product is a steel and iron product produced by smelting and rolling process, which is widely used in fields such as construction, manufacturing, transportation and energy, and has characteristics such as high strength, plasticity and durability. Rolling refers to the process of processing blank into a certain shape through hot rolling, cold rolling and other processes. When processing the ferrous metal smelting and rolling product, especially the black metal material formed into a sheet after rolling, it is often necessary to weld the rolled iron plate, steel plate and other materials to increase the material area or add materials at special positions. However, the existing ferrous metal smelting and rolling product welding equipment is mainly used to solve the positioning between two target materials during welding to avoid misplacement of the plate during welding, which affects the processing quality.

[0003] A ferrous metal smelting and rolling product welding device is disclosed in Chinese patent No. CN214868236U, which includes a bottom plate, a fixed plate and a positioning device arranged on the top of the bottom plate, a through slot is formed in the fixed plate, a connecting rod is arranged on the surface of the through slot, an extrusion ball is arranged at the bottom of the connecting rod, a metal plate is arranged in the through slot, the extrusion ball abuts against the metal plate, a welding device is arranged on the top of the fixed plate, the positioning device includes a sliding groove, the sliding groove is formed on the top of the bottom plate, a moving plate is arranged in the sliding groove, the moving plate is slidingly connected with the sliding groove, and a fastening bolt is arranged in the bottom plate. The positioning device can limit and fix the metal plate to prevent accidental movement of the metal plate during welding, thereby improving the welding quality of the metal plate. The extrusion ball can assist in limiting and positioning the metal plate.

DETAILED DESCRIPTION

[0035] In order to make the person in the art better understand the present application scheme, the technical scheme in the embodiment of the present application will be described clearly and completely in combination with the drawings in the embodiment of the present application.

[0036] Example one:

[0037] As shown in Figures 1-9 A ferrous metal smelting and rolling product welding device includes a cabinet 10, the cabinet 10 is fixedly connected with a frame body 11, a loading platform 12 is arranged in the frame body 11 in a lifting manner, a ferrous metal plate 37 is carried on the loading platform 12, a plurality of pin holes 13 are formed in the surface of the loading platform 12, a positioning pin 14 can be threadedly connected in each pin hole 13, each positioning pin 14 can abut against the edge of the ferrous metal plate 37, supports 26 are fixedly connected on the cabinet 10, slide rails 27 located at the welding position of the ferrous metal plate 37 are fixedly connected between the supports 26, slide blocks 28 are slidably connected in the slide rails 27, a welding gun 29 is fixedly connected to the bottom of each slide block 28, a lead screw 30 is rotatably connected in the slide rail 27, a motor 31 is fixedly connected to the side of the support 26 and located at the corresponding position of the lead screw 30, and the power output end of the motor 31 is in transmission connection with the lead screw 30.

[0038] The ferrous metal plate 37 is welded by the welding gun 29, and the slide block 28 can be driven by the lead screw 30 to move horizontally, so that the welding gun 29 can automatically weld the ferrous metal plate 37. By arranging the pin hole 13 and the positioning pin 14, the side edge of the ferrous metal plate 37 can be accurately positioned, the position of the ferrous metal plate 37 during welding can be ensured to be accurate, and the processing precision and quality can be improved.

[0039] As shown in Figures 1-9 Two pressing plates 15 are arranged above the loading platform 12 and located at both sides of the slide rail 27, a through hole 16 is formed in each pressing plate 15 and located at the corresponding position of each pin hole 13, a first air cylinder 20 is fixedly connected to the support 26 and located at the corresponding position of each pressing plate 15, a connecting seat 21 is fixedly connected to the upper side of each pressing plate 15 and located at the corresponding position of each first air cylinder 20, and the elongated end of each first air cylinder 20 penetrates through the support 26 and is clamped with the corresponding connecting seat 21.

[0040] The pressing plate 15 can press and cover the ferrous metal plate 37, so that the ferrous metal plate 37 can be kept flat by applying pressure during welding, and the bending deformation of the ferrous metal plate 37 caused by internal stress during welding can be avoided, so that the shape and quality of the final product can be ensured. The pressing plate 15 that presses and covers the ferrous metal plate 37 can also have the effect of clamping and fixing the ferrous metal plate 37, so that the accuracy of the position of the ferrous metal plate 37 during welding can be further ensured. By arranging the through hole 16, the positioning pin 14 can penetrate through the through hole 16 during the pressing and covering process of the pressing plate 15, so that the pressing and covering action of the pressing plate 15 on the ferrous metal plate 37 is not hindered by the positioning pin 14.

[0041] As shown in Figures 1-9 A vibration generator 19 is fixedly connected to each pressing plate 15, and a vibration sensor 23 for detecting the vibration amplitude and frequency is fixedly connected to the corner of each pressing plate 15.

[0042] By setting the vibration generator 19, the black metal plate 37 can be subjected to vibration aging stress relief after welding, and the residual stress in the black metal plate 37 can be eliminated, so that the internal grain distribution of the black metal plate 37 is uniform, and the black metal plate 37 is prevented from deforming due to internal stress and its material performance is improved.

[0043] As shown in Figures 1-9 The bottom side of the carrier 12 is fixedly connected with a plurality of first electromagnets 17 below the black metal plate 37, and the upper side of the pressing plate 15 is fixedly connected with a second electromagnet 18 at a position corresponding to each first electromagnet 17, and the magnetic poles of the first electromagnet 17 and the second electromagnet 18 are opposite.

[0044] By setting the first electromagnet 17 and the second electromagnet 18, the pressing plate 15 and the carrier 12 are attracted to each other during the vibration aging process, so that the carrier 12 and the pressing plate 15 always firmly clamp the two sides of the black metal plate 37, avoiding separation of the carrier 12 and the pressing plate 15 due to the application of vibration, so that the black metal plate 37 is separated from the clamping state of the carrier 12 and the pressing plate 15, and at the same time, it ensures that the vibration aging can uniformly and stably act on the inside of the black metal plate 37, thereby ensuring the stress relief effect.

[0045] As shown in Figures 1-9 The bottom side of the carrier 12 is fixedly connected with two first hinges 32, the inner side of the cabinet 10 is fixedly connected with a plurality of second hinges 33, the movable end of each second hinge 33 is fixedly connected with the movable end of the first hinge 32, the cylinder body of each second cylinder 34 is fixedly connected with the corresponding first hinge 32, and the spring 35 is fixedly connected between the cylinder body of each second cylinder 34 and the corresponding first hinge 32. The rubber pad 22 is arranged between the end of the connecting seat 21 and the pressing plate 15 in each connecting seat 21, and the air pressure controller 36 is fixedly connected in the cabinet 10.

[0046] When the vibration aging stress relief is performed, the carrier 12 is lowered to be separated from the frame 11, so that the pressing plate 15 and the carrier 12 are in a floating state, and the spring 35 and the rubber pad 22 are elastically damped, thereby avoiding direct transmission of vibration to the cabinet 10 and the slide rail 27 when the vibration aging is applied, avoiding long-term vibration causing the position of the vibration generator 19 and other components to deviate or even be damaged, protecting the main components and reducing the risk of equipment failure.

[0047] In this embodiment, initially, the operator connects the power supply and the control system of the patent, at this time the air pressure controller 36 injects air pressure into the second cylinder 34, so that the inclined plate frame 24 and the guide inclined surface 25 are stably abutted, then the carrier 12 is stably sleeved in the frame body 11, the pressing plate 15 is located at a high position and does not contact the carrier 12, the operator selects the corresponding pin hole 13 according to the size of the black metal plate 37 to be processed, and then screws the positioning pin 14 into the corresponding pin hole 13, and then places two pieces of the black metal plate 37 to be processed on the surface of the carrier 12, so that the positioning pin 14 can accurately abut against the edge of the black metal plate 37, realizing accurate positioning of the black metal plate 37 and ensuring the accuracy of subsequent welding of the black metal plate 37.

[0048] Subsequently, the air pressure controller 36 injects air pressure into the first cylinder 20, so that the first cylinder 20 extends outward and pushes the pressing plate 15 to move downward, until the pressing plate 15 completely covers the surface of the black metal plate 37 and exerts pressure on the black metal plate 37, at this time the positioning pin 14 passes through the corresponding through hole 16, then the control system starts the welding gun 29, and controls the motor 31 to drive the lead screw 30 to rotate, so as to drive the sliding block 28 to move along the direction of the slide rail 27 with the welding gun 29, then automatic welding of the welding position of the black metal plate 37 is realized.

[0049] After the welding processing is completed, the operator starts the first electromagnet 17 and the second electromagnet 18 to generate electromagnetic attraction, so that the carrier 12 and the pressing plate 15 attract and clamp the black metal plate 37, and controls to remove all air pressure of the second cylinder 34, at this time the control first cylinder 20 is pressed, then the pressing plate 15 presses the black metal plate 37 to move downward together with the carrier 12, and the spring 35 is compressed, at this time the carrier 12 and the frame body 11 are completely separated to realize floating, at this time the vibration generator 19 is started to apply vibration, and the black metal plate 37 is vibrated to perform stress relief, remove the internal stress generated during rolling and welding of the black metal plate 37, so as to avoid deformation of the black metal plate 37 and ensure the processing quality.

[0050] Since the carrier 12 and the pressing plate 15 are in a floating state at this time, and the rubber pad 22 and the spring 35 can buffer and weaken the vibration directly transmitted to the slide rail 27 and the cabinet 10 during the vibration process, the important structure such as the welding gun 29 is effectively protected, and the problems of loosening, misalignment and even damage in the long-term vibration process are avoided.

[0051] When the vibration aging is completed, the gas pressure is injected into the second cylinder 34 again, and the first cylinder 20 is controlled to retract, so that the platform 12 and the pressing plate 15 re-grip the ferrous metal plate 37 and rise until the inclined plate frame 24 and the guide inclined surface 25 stably abut, so that the platform 12 is firmly combined with the frame body 11. At this time, the second cylinder 34 does not push the platform 12, and the first cylinder 20 continues to pull the pressing plate 15 upward, so that the ferrous metal plate 37 is exposed, and the operator can take out the ferrous metal plate 37, and the machining work is completed.

[0052] The first electromagnet 17, the second electromagnet 18, the first cylinder 20, the vibration sensor 23, the second cylinder 34, the gas pressure controller 36 and the like are mature prior art, and the structures in the drawings are only schematic, and will not be described herein.
