Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. As used herein, "plurality" includes two and more than two items. As used herein, "above a certain number" should be understood to mean a certain number and a range greater than a certain number.
Sectional door is very common at present. In the conventional technology, according to the difference between actual materials and application scenes, the frames of the frame-splicing door may be connected in different connection modes, such as angle connectors, mortise and tenon joints, and the like. However, these connection methods are all mechanical connection methods, and in the actual preparation process, the splicing method depends on manual operation, and additional parts and tedious splicing steps are required to be purchased.
Welding is a common way of connecting metal components, but the welding marks of welding seriously affect the practical use performance of the frame-split door, so that the frame-split door manufactured by welding has not been considered by the technicians for a long time. Particularly, when the welding is pieced together the frame door, need follow the exposed surface of frame and weld to need all weld at two exposed surfaces that the frame is relative, just can make stable the combining together between the frame that meets, otherwise produce the crack extremely easily, lead to door frame major structure to collapse. However, the welding method can seriously affect the practical use of the frame-spliced door, and obvious welding marks are generated on the exposed surface of the door, and the welding marks not only greatly affect the visual performance of the door, but also easily scratch a user, so that the frame-spliced door is basically impractical. This has become a common general knowledge of those skilled in the art.
In order to prepare the frame splicing door by adopting a welding mode, save the production process of the frame splicing door and reduce the production cost of the frame splicing door, the inventor develops a new method, thinks of a technical idea of single-side welding and adopting door core plate bonding for auxiliary fixation, and provides a set of specific technical scheme. The technical scheme is as follows.
According to one embodiment of the invention, the corner-code-free frame-spliced door comprises a door frame, an adhesive layer and a door core plate, wherein the door frame is composed of a plurality of metal frames which are sequentially connected, joints among the metal frames are connected in a welding mode, and a welding seal is welded on one side surface of the door frame; the door core plate is covered on one side surface of the door frame with the welding seal, and the adhesive layer is arranged between the door core plate and the door frame 100. Optionally, the other side surface of the door frame has no solder mark thereon.
In one specific example, the metal bezel is an aluminum bezel or an aluminum alloy bezel.
In one specific example, the abutting surfaces of two adjacent metal frames are matched oblique tangent planes. It will be understood that by "diagonal cut" is meant an oblique connection between the cut and the adjacent frame wall, which makes the facing surface appear to be oblique to the frame wall. To the welded exempt from angle sign indicating number piece together frame door, connect with the slant tangent plane between two adjacent metal frames, can further strengthen the area of contact between the adjacent frame to effectively strengthen its cohesion.
Furthermore, the cutting angle of the oblique section of the metal frame is 30-60 degrees. It will be understood that the cut angle is the acute angle defined by the diagonal cut plane and the frame wall adjacent to the diagonal cut plane. Optionally, the chamfer angle of the oblique tangent plane of the metal frame is 30 ° to 60 °.
To facilitate understanding of a detailed schematic view of welding the door frame 100 in the corner-splicing-free door of the present invention, please refer to fig. 1, which shows a detailed implementation manner of the door frame 100.
Specifically, the doorframe 100 includes a top frame 110, a bottom frame 120, a first side frame 130 and a second side frame 140.
In one specific example, the top bezel 110 is disposed opposite the bottom bezel 120, the first side bezel 130 is disposed opposite the second side bezel 140, the first side bezel 130 is respectively connected to one side of the top bezel 110 and the bottom bezel 120, and the second side bezel 140 is respectively connected to the other side of the top bezel 110 and the bottom bezel 120.
In one specific example, the interface between top frame 110 and first side frame 130 is a beveled cut.
In one specific example, the interface between the top frame 110 and the second side frame 140 is a slanted cut.
In one specific example, the interface between the bottom frame 120 and the first side frame 130 is a diagonal surface.
In one specific example, the interface between the bottom frame 120 and the second side frame 140 is a diagonal surface.
Further, the top frame 110, the bottom frame 120, the first side frame 130 and the second side frame 140 form a rectangular door frame, and the top frame 110 is parallel to the bottom frame 120 and perpendicular to the first side frame 130 and the second side frame 140.
It is understood that the top frame 110 and the first side frame 130, the top frame 110 and the second side frame 140, the bottom frame 120 and the first side frame 130, and the bottom frame 120 and the second side frame 140 are connected by welding, and the welding stamp 150 is disposed on the non-exposed surface of the top frame 110 and the first side frame 130. It will be appreciated that the so-called non-exposed surface, i.e., the surface covered with the door core plate 300, is masked from view or contact during ordinary use by the covering with the door core plate 300.
When the metal frame is too thin, the hardness of the metal frame is hard to support the whole door frame 100 and the door core plate 300, and deformation is easily generated. In one specific example, the metal frame is hollow, and the wall thickness of the metal frame is more than or equal to 0.8 mm. Furthermore, the wall thickness of the metal frame is 0.8 mm-2 mm. For example, the wall thickness of the metal frame is 0.8mm, 1mm, 1.5mm, 2 mm; when the metal frames are too thin, the manner of single-side welding between the adjacent metal frames is difficult to provide enough binding force for the door frame 100, so that the door frame 100 is easy to separate and collapse; when the metal frame is too thick, the door frame is too heavy.
It is understood that the welding mark 150 may be a plurality of welding spots formed on the joint by spot welding, or a welding line formed by continuously welding in a line. In one specific example, the solder stamp 150 is in the form of an elongated strip that fills or covers the seam between adjacent metal rims. Optionally, in order to further improve the bonding force between the adjoining solder marks 150, the difference between the length of the seam and the length of the solder mark 150 is 5mm to 10mm, and particularly, the difference between the length of the seam and the length of the solder mark 150 is 10 mm. On the one hand, the length of the solder print 150 cannot be too short, otherwise it is difficult to provide enough bonding force to stably bond the adjacent metal frames together. On the other hand, the length of the weld mark 150 cannot be the same as or too close to the length of the seam, which may affect the covering effect of the door core plate 300 on the door frame 100 as a whole.
In the actual manufacturing process, due to problems such as tolerance and surface flatness, a seam with a certain width always exists between the seams of the adjacent metal frames. In the case of the conventional mechanically coupled sectional door, the seam does not have a significant effect, but in the case of the door frame 100 formed by one-side welding, it is preferable to control the width of the seam between the adjacent metal jambs. Optionally, in one specific example, the width of the gap between the seams of the adjacent metal frames is less than or equal to 0.3 mm.
Further, welding at the joint between adjacent metal frames forms a welding mark 150 with a surface protruding from the surfaces of the two side frames. In order to prevent the covering effect of the door core plate 300 on the whole door frame 100 from being affected as much as possible, the height of the solder marks 150 protruding from the surfaces of the metal frames at the two sides is less than or equal to 0.2 mm. Optionally, in order to make the height of the solder mark 150 protruding from the metal frame surfaces on both sides of the solder mark less than or equal to 0.2mm, the solder mark 150 may be formed by laser welding.
The door frame 100 provided in the above embodiment has only one side surface seam welded, and such a welding manner can only prepare the door frame 100 temporarily combined together, and the door frame 100 prepared in this way may be directly deformed or split, or may be rapidly split during a test process, and is difficult to put into practical use in order to overcome this problem, in the embodiment of the present invention, an adhesive layer 200 and a door core plate 300 are further provided, and the adhesive layer 200 is provided between the door core plate 300 and the door frame 100. The adhesive layer 200 can serve to adhere the door core 300 to the door frame 100, and can reinforce the door frame 100 with the door core 300, so that the corner-splice-free door can be stably combined together when only one side of the seam is welded.
As shown in fig. 2, in one particular example, the outer edge of the adhesive layer 200 is corrugated. Through practical tests, compared with the method of directly coating the adhesive layer 200 on the whole surface, the outer edge of the adhesive layer 200 is coated in a corrugated shape, so that the use of the adhesive layer 200 material is reduced on the premise of ensuring the binding force between the door core plate 300 and the door frame 100 and further ensuring the stability of the door frame 100, the adhesive layer 200 is prevented from being exposed out of the side edge of the corner-free spliced frame door, and the practical use performance of the corner-free spliced frame door is ensured.
It is understood that the material of the adhesive layer 200 is selected corresponding to the material of the door frame 100 and the door core 300, and it should be able to effectively adhere the door frame 100 and the door core 300.
In one specific example, optionally, the door core panel 300 is a glass panel and the adhesive layer 200 is a glass cement adhesive layer. Further, the door core plate 300 is a silver mirror glass plate. Through practical tests, the glass cement adhesive layer can effectively and stably adhere the aluminum door frame 100 and the glass plate together.
In one specific example, the thickness of the door core panel 300 is 3mm to 10 mm. A door core panel 300 between this thickness range has sufficient strength by itself to bond the metal jambs together, and on the other hand the door core panel 300 is not so thick and heavy as to cause collapse of the door frame.
Further, another embodiment of the present invention further provides a method for manufacturing a corner-free frame-spliced door, which includes the following steps:
splicing a plurality of metal frames in sequence, welding adjacent metal frames to form a door frame, wherein each metal frame is provided with an adhesive part, each adhesive part is provided with an adhesive surface, and welding marks at the welding positions and the adhesive surfaces are integrally positioned on the same side surface of the door frame;
welding seams among the metal frames on the surface of one side of the door frame;
and adhering the door core plate on the adhesive surface of the door core plate through the adhesive layer, and covering the door core plate with welding marks.
In one specific example, the metal frame is made of aluminum or aluminum alloy. The 6063 aluminum profile is taken as a specific example in the embodiment.
In one specific example, before welding the metal frame, the method further comprises the step of cutting and cutting the metal. In the step of cutting, the cutting angle is controlled so that the joint surface of the metal frame is an oblique section. Furthermore, the cutting angle of the oblique section of the metal frame is 30-60 degrees. It will be understood that the cut angle is the acute angle defined by the diagonal cut plane and the frame wall adjacent to the diagonal cut plane. Optionally, the chamfer angle of the oblique tangent plane of the metal frame is 30 ° to 60 °.
In one specific example, in the step of cutting and cutting the metal, the size deviation of the metal frame is required to be less than or equal to 1mm, and the angle deviation of the oblique tangent plane of the metal frame is required to be less than or equal to 0.3 degrees. The purpose of controlling the size deviation of the metal frames and further controlling the angle deviation of the oblique tangent planes of the metal frames within a certain range is to ensure that the seams between the adjacent metal frames are as small as possible, so that the metal frames can be effectively welded.
In one specific example, the metal frame is a hollow metal frame, and the wall thickness of the metal frame is more than or equal to 0.8 mm. Furthermore, the wall thickness of the metal frame is 0.8 mm-2 mm.
In one specific example, before welding the metal frames, the method further comprises the step of forming door hinge holes in the corresponding metal frames. Optionally, the hole position deviation of the door hinge hole is within 0.5 mm. The door is generally required to be mounted to the wall through a door hinge hole. The door hinge hole should be formed before the metal frame is welded, and if the door hinge hole is formed in a subsequent process, the welded metal frames may be separated from each other by an impact force generated when the door hinge hole is formed.
In one specific example, the welding is performed in such a manner that continuous welding is performed in one line. This allows the solder print to be in the form of an elongated strip that fills or covers the seam between adjacent metal rims. Optionally, in order to further improve the bonding force between the adjoining solder marks, the difference between the length of the seam and the length of the solder mark is 5mm to 10mm, in particular the difference between the length of the seam and the length of the solder mark is 10 mm. Preferably, the weld is located in the middle of the seam, i.e. both ends of the weld are emphasized within the seam. The specific position of the solder mark can refer to the structural schematic diagram shown in fig. 1.
In one specific example, during the welding process, the seam between the metal frames is welded by laser welding. Laser welding is an efficient and precise welding method using a laser beam with high energy density as a heat source, and can locally melt a workpiece to form a specific molten pool by controlling parameters such as the width, energy, peak power, repetition frequency and the like of laser pulses. The welding positioning precision of laser welding is high, the joints among the metal door core plates can be accurately welded, the height of the formed welding mark is low, and the subsequent laying of the door core plates cannot be influenced.
In one specific example, the width of the laser during laser welding is 0.3mm to 0.8 mm.
It can be understood that, in the welding process, the metal frames need to be spliced together in sequence to make the adjacent metal frames align and abut against each other. Optionally, the position of each metal frame can be fixed by using a clamp. The process can be completed by adopting mechanical equipment, so that the use of manpower is avoided, and the operation efficiency and the operation precision are improved.
In one specific example, an industrial robot or a mechanical arm with a fiber laser welding function can be selected for laser welding, the operation program of the industrial robot or the mechanical arm can be preset, and all seams in the door frame which is assembled preliminarily are welded. The welding machine is operated by means of an industrial robot or a mechanical arm, welding precision can be guaranteed as far as possible, welding marks meeting actual requirements are obtained, manpower is eliminated, operating efficiency is improved, and precision is reduced.
In one specific example, the DAC power during laser welding is 50% to 80%.
After welding, the protruding height of the welding seal position after welding is required to be within 0.2mm, and the condition of welding through does not exist. The deviation of the length and width of the finished product is less than or equal to 1mm, the deviation of the diagonal line is less than or equal to 1mm, the exposed surface of the door frame, namely the splicing gap of the surface of one side without the door core plate is less than or equal to 0.3mm, and the deviation of the splicing height and the deviation of the frame are within 0.3 mm.
In one specific example, in the process of attaching the adhesive layer and the door core plate in an aligned manner, the adhesive layer may be attached to one side surface of the door frame, which has the welding mark, so that the adhesive layer initially fixes each metal frame in the door frame, and cracking in the subsequent attaching process is prevented.
In one specific example, the material of the adhesive layer is selected from glass cement, and further, may be neutral glass cement. When the adhesive layer is attached to the surface of the door frame, the adhesive layer may be attached in a shape similar to that shown in fig. 2, so that the inner side edge of the adhesive layer is matched with the inner side surface of the door frame, and the outer side edge of the adhesive layer is located on the door frame and is corrugated. The corrugation may be uniform or non-uniform. The outer edge of the adhesive layer is attached in a corrugated shape, the use of the adhesive layer material can be reduced on the premise of ensuring the binding force between the door core plate and the door frame and further ensuring the stability of the door frame, meanwhile, the adhesive layer is prevented from being exposed out of the side edge of the corner-code-free spliced frame door, and the actual use performance of the corner-code-free spliced frame door is ensured.
After the adhesive layer is adhered to the surface of the door frame, the door core plate and the surface of the side, where the adhesive layer is adhered to the door frame, of the door core plate are aligned and pressed on the surface of the door frame, and the door core plate, the adhesive layer and the door core plate are continuously extruded to be stably combined together.
In one specific example, the material of the door core plate is glass, and further specifically, silver mirror glass may be selected in consideration of beauty and practicality.
In one specific example, after the door core plate is bonded to the door frame, the method further includes: and pressing the door core plate and the door frame, so that the door core plate is fully abutted against the adhesive layer and the door frame and is fixed for more than 6 hours. Optionally, the pressure of the pressing is 1000Pa to 10000 Pa.
