Description

Technical Field

[0001] The invention belongs to the technical field of identification plate welding and relates to a welding device for processing stainless steel identification plates. Background Art

[0002] Stainless steel signboards are advertising signboards made of stainless steel plates through corrosion, die-casting or printing. Stainless steel has good resistance to atmospheric and freshwater corrosion, and can be decorated after corrosion, polishing and brushing. Stainless steel signboards are widely used in various places, such as lobby signboards, guide signs, water signs, welcome signs, etc. for hotel supplies, as well as signboards in public places such as shopping malls, banks, airports, and stations. Stainless steel signboards have the characteristics of metallic texture, high-end feeling, and strong solemnity. They will not rust and have a long service life, so they are widely used. In the production process, it is necessary to go through multiple processes such as planing, bending, welding, cleaning, corrosion, polishing, brushing, etc. to produce high-quality stainless steel signboards, especially large stainless steel plates, which have a certain thickness and weight, and need to be precisely adjusted and welded to improve their stability.

[0003] The existing stainless steel plate welding process generally adopts direct welding or a more cautious two-way welding method. Although direct welding seems to be efficient, it is often difficult to fully guarantee the strength and sealing of the welded joint due to problems such as uneven heat distribution and material stress concentration during the welding process. Although the two-way welding improves the welding quality to a certain extent, the basic connection is formed by the initial welding, and then strengthened and corrected by the secondary welding, this method undoubtedly increases the production cycle, affects the overall operation efficiency, and increases the cost.

[0004] Although theoretically the production efficiency can be maximized if the welding is completed in one go, in actual operation, due to the high hardness and high thermal conductivity of stainless steel, coupled with the complexity of controlling welding parameters (such as current, voltage, and welding speed), it is very easy to cause incomplete welding. This not only includes defects such as pores, slag inclusions, and lack of fusion that may appear on the weld surface, but also residual stress may be generated inside the material due to improper welding heat input, affecting the stability and service life of the structure.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] like Figure 1-7 As shown, the present invention is a welding device for processing stainless steel identification plates, including a base plate 1, an identification plate 32, a circular frame 5, and a motor 58; a first rotating shaft 53 is rotatably provided on the circular frame 5, and is driven by the motor 58 to rotate, one end of the first rotating shaft 53 extends out of the circular frame 5, and a cutting disk 57 is sleeved on the outer side of the first rotating shaft 53, and the outer edge of the cutting disk 57 shrinks inwardly, so that when two identification plates 32 are cut, the connection between the two identification plates 32 is cut into a V-shaped groove; a connecting plate 59 is provided in the circular frame 5, and a welding gun 591 is provided in the connecting plate 59, and the welding gun 591 forms a V-shaped groove so that the two identification plates 32 are welded into a whole.

[0029] like Figure 4As shown, firstly, the two identification plates 32 to be welded are placed on the supporting plate 23, and the two-way screw 3 is rotated to make the two clamping plates 31 move inward synchronously, so as to clamp the identification plates 32; when the identification plates 32 are clamped, the motor 58 is driven, and the gear 55 and the transmission belt 56 are engaged, so as to drive the driving shaft 51, the first rotating shaft 53, and the second rotating shaft 54 ​​to rotate, and then drive the grinding wheel 52 and the cutting disc 57 to rotate, and with the help of the contraction of the second cylinder 43, the circular frame 5 is pulled forward;

[0030] During the high-speed rotation, the cutting disc 57 accurately cuts the contact surfaces of the two mutually attached identification plates 32 with its sharp blade, and finally the contact end surfaces of the two identification plates 32 are cut into a V-shaped groove. The V-shaped groove provides a contact area for the subsequent welding step, which is conducive to the formation of the weld and the improvement of the quality.

[0031] Next, the welding gun 591 is activated, and its nozzle is precisely aligned with the V-shaped groove to release a high-temperature welding arc. In this step, the welding material is precisely melted and filled into the V-shaped groove. As the welding gun 591 moves at a constant speed, the weld gradually solidifies, thereby firmly connecting the two identification plates 32 together.

[0032] After the welding is completed, in order to ensure the consistency and aesthetics of the surface of the sign, the grinding wheel 52 is immediately involved in the work. The grinding wheel 52 effectively grinds the welding area. This step removes the uneven surface defects generated during the welding process, so that the welding part is perfectly integrated with the surrounding sign surface, ensuring the durability and aesthetics of the sign in subsequent use.

[0033] When there is an angle between the two identification plates 32 to be welded, such as Figure 5 As shown: the first cylinder 2 contracts, pulling the cylinder push plate 21 downward, and then the pull rod 22 is subjected to force, pulling the support plate 23 to move, so that the slide bar 24 moves downward in the guide groove, so that the two support plates 23 form a certain angle, and then the identification plate 32 to be welded is fixed to the support plate 23; at the same time, the second cylinder 6 extends upward, driving a section of the circular frame 5 to fold upward, so that the cutting disc 57 does not contact the identification plate 32, and with the help of the contraction of the second cylinder 43, the circular frame 5 is pulled forward;

[0034] The welding gun 591 is activated, and its nozzle is precisely aligned with the groove formed between the two identification plates 32, and releases a high-temperature welding arc, thereby firmly connecting the two identification plates 32 together; after the welding is completed, the grinding wheel 52 immediately intervenes to effectively grind the welding area.

[0035] In this embodiment, four supporting rods 26 are provided on the bottom plate 1, and a supporting plate 23 is provided on every two supporting rods 26. The supporting plate 23 is used to support the identification plate 32.

[0036] The bottom plate 1 is provided with a first cylinder 2, and the output end of the first cylinder 2 is provided with a cylinder push plate 21, and two pull rods 22 are hinged on the cylinder push plate 21, and the upper ends of the pull rods 22 are respectively hinged with the supporting plate 23; a guide plate 25 is provided on the supporting rod 26, and a guide groove is provided in the guide plate 25, and the supporting plate 23 and the supporting rod 26 are rotatably connected, and a slide rod 24 is provided on the supporting plate 23 to slide with the guide groove;

[0037] Preferably, the support plate 23 is provided with a bidirectional screw 3, and the bidirectional screw 3 is provided with two clamping plates 31, and when the bidirectional screw 3 is rotated, the two clamping plates 31 move inward or outward synchronously to clamp or release the identification plate 32;

[0038] The supporting plate 23 is not only used to support the identification plate 32, but also realizes the welding of two identification plates at different angles through the combination of the first cylinder 2, the cylinder push plate 21 and the pull rod 22; the guide plate 25 on the supporting rod 26 cooperates with the sliding rod 24 on the supporting plate 23 to ensure the stability and precision of the supporting plate 23 during the angle change process; in addition, the supporting plate 23 is also equipped with a bidirectional screw 3 and two clamps 31. By rotating the bidirectional screw 3, the identification plate 32 can be easily clamped or released. This design greatly improves the safety and accuracy of the processing process.

[0039] In this embodiment, the circular frame 5 is provided with a driving shaft 51 and a second rotating shaft 54, one end of the second rotating shaft 54 ​​and the driving shaft 51 are extended out of the circular frame 5, and the extended end of the driving shaft 51 is connected to the motor 58; the extended ends of the driving shaft 51, the second rotating shaft 54 ​​and the first rotating shaft 53 are all sleeved with a gear 55, and the outer side of the gear 55 is commonly provided with a transmission belt 56, and under the drive of the motor 58, the driving shaft 51, the second rotating shaft 54 ​​and the first rotating shaft 53 rotate synchronously;

[0040] Preferably, the second rotating shaft 54 ​​is arranged so that the circular frame 5 is divided into two sections, and the opposite ends of the two sections are both rotatably connected to the outer wall of the circular frame 5;

[0042] The design of the circular frame 5 is not only provided with a driving shaft 51 and a second rotating shaft 54, but also realizes the synchronous rotation of the first rotating shaft 53, the second rotating shaft 54 ​​and the driving shaft 51 through the combination of the gear 55 and the transmission belt 56. This design not only simplifies the mechanical structure, but also improves the continuity and efficiency of the welding operation. In particular, the setting of the second rotating shaft 54 ​​enables the circular frame 5 to be divided into two sections. Through the combination of the second cylinder 6 and the stretching rod 61, the telescopic and folding functions of the circular frame 5 are realized, further enhancing the flexibility and applicability of the device.

[0044] During the welding process, the welding gun 591 in the connecting plate 59 is connected to the connecting plate by screwing, so that the position of the welding head can be adjusted to ensure the welding quality. At the same time, the spring 72 between the second connecting plate 71 and the connecting plate 59 provides necessary buffering for the welding gun 591, reduces vibration during welding, improves welding accuracy, and also ensures that the welding gun head of the welding gun 591 fits the identification plate 32, thereby ensuring the welding accuracy.
