Description

Technical Field

[0001] The present invention relates to the technical field of template processing, and more specifically, to a production device and method for a universal internal corner template. Background Art

[0002] Building plastic templates are a new type of green environmental protection product. Different from traditional wooden templates, aluminum alloy templates, and steel templates, plastic templates generally adopt special environmentally friendly high-tech composite materials and are formed by methods such as molding. They have the advantages of energy conservation, environmental protection, recyclability, and low amortization cost. To a certain extent, they can replace traditional steel templates, aluminum templates, wooden templates, and square timbers. Currently, plastic templates can be used in various engineering fields, are easy to assemble and use, can save a large amount of labor, and reduce construction costs. They are widely used in construction projects such as pipe galleries, drainage ditches, tunnels, culverts, shear walls, and bridges.

[0003] During the processing of templates, it is necessary to splice and weld them. First, the template components to be welded are accurately butt-jointed and firmly fixed to ensure that the weld positions are accurate and meet the design requirements. For some templates with angular or shape requirements, auxiliary tools such as jigs and positioning pins may be required for positioning. However, during the welding process of templates, uneven heating and cooling during welding will cause the templates to deform. The metal in the weld area expands when heated and contracts when cooled, resulting in a large temperature difference between the weld and the surrounding metal. When cooling, the contractions are inconsistent, generating large welding stresses, which can cause the templates to deform or even crack. How to invent a production device and method for a universal internal corner template to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

One ends of the air bags away from the exhaust holes are fixedly connected with pressure switches. Electric heating grids are fixedly connected to the interiors of the cavities. The electric heating grids are located on one sides of the exhaust holes.

[0010] Preferably, the positioning components further include motors and rotating disks. The rotating disks are located inside the grooves. The motors are fixedly connected to the side walls of the limiting top plates. One ends of the motors penetrate through the inner walls of the grooves and are fixedly connected to the side walls of the rotating disks. One ends of the rotating disks away from the motors are fixedly connected with pressing plates. There are two pressing plates, and the two pressing plates are rotationally symmetrically distributed about the central axes of the rotating disks. The pressing plates are arc-shaped.

[0011] Preferably, the positioning components further include extension cylinders. The extension cylinders are fixedly connected to the side walls of the limiting top plates. Knock rods, limiting rings and return springs are arranged inside the extension cylinders. The outer diameters of the knock rods are smaller than the middle inner diameters of the exhaust holes.

[0012] Preferably, the limiting rings are slidably connected to the inner walls of the extension cylinders. Moving rods are fixedly connected to the outer walls of the limiting rings.

[0014] A method for a universal internal corner template production device as described above, comprising the following steps: S1: Template clamping and fixing Place the special splicing template on the special splicing template fixing jig, and use the jig to fix the position of the template to be processed according to the splicing position requirements. At the same time, place the conventional plastic template on the conventional plastic template fixing jig, and use the corresponding jig to fix the position of the template to be processed according to the splicing position requirements; S2: Shaping processing The special splicing template fixing jig and the conventional plastic template fixing jig move to the shaping processing station through the moving workbench, and then the special splicing template and the conventional plastic template are respectively cut or milled by two groups of shaping processing equipment; S3: Splicing and fixing Remove the processed conventional plastic template and the special splicing template from the corresponding fixing jigs, and place them on the splicing fixing plate.

[0015] The beneficial effects of the present invention are: Before local spot welding or actual welding, the temperature of the spliced formwork is increased through an electrically heated grid frame, so that while the limit top plate realizes positioning, it can also achieve the effect of preheating the formwork. By preheating, the temperature difference between the weld seam and the base metal is reduced, and the thermal expansion and contraction of each part during welding are relatively uniform, which can effectively reduce the welding stress and deformation degree. At the same time, the solidification process of the weld metal is more stable, reducing the probability of crack generation, improving the welding quality, reducing the rejection rate, and saving production costs. At the same time, during the preheating process of the formwork, as the temperature rises, the airbag will expand. Through the extrusion of the pressure switch and the inner wall of the cavity, the motor drives the rotating disc to rotate, and at the same time starts the automatic welding equipment for welding. Through the extrusion plate and the column, the movable rod drives the limit ring to compress the return spring, and at the same time drives the knocking rod to move towards the extension cylinder. As the rotating disc continues to rotate, the knocking rod can be quickly reset by the elastic recovery of the return spring, so as to realize the knocking on the surface of the formwork, making it produce a vibration effect, and then realizing the reciprocating knocking vibration of the formwork, so as to promote the redistribution of stress, reduce the peak value of residual stress, effectively reduce the problems caused by stress concentration, improve the dimensional stability and structural strength of the formwork, and enhance the reliability of the formwork welding joint, and extend the service life of the formwork.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example 1. Refer to Figures 1-12, a universal internal corner template production device, including a movable workbench 1 and a fixed workbench 9. On one side of the movable workbench 1, there is a shaping and processing device 5. On one side of the fixed workbench 9, there is an automatic welding device 7. The automatic welding device 7 is fixedly connected with a welding head 71. The fixed workbench 9 is connected with a splicing fixing plate 3, a welding fixing plate 6, and a trimming and inspection fixing jig 8. The splicing fixing plate 3 is connected with a fixing frame 11. It also includes: A positioning component 10, which is located above the fixed workbench 9 and is used for preheating the welding plates.

[0021] A method for a universal internal corner template production device, including the following steps: S1: Template clamping and fixing Place the special splicing template on the special splicing template fixing jig 4, and use the jig to fix the position of the template to be processed according to the splicing position requirements. At the same time, place the conventional plastic template on the conventional plastic template fixing jig 2, and use the corresponding jig to fix the position of the template to be processed according to the splicing position requirements. S2: Shaping and processing The special splicing template fixing jig 4 and the conventional plastic template fixing jig 2 move to the shaping and processing station through the movable workbench 1, and then the two shaping and processing devices 5 respectively perform cutting or milling processing on the special splicing template and the conventional plastic template. S3: Splicing and fixing Remove the processed conventional plastic template and the special splicing template from the corresponding fixing jigs, and place them on the splicing fixing plate 3. Perform splicing and fixing through the positioning component 10, perform splicing and forming according to the forming requirements of the universal internal corner plastic template, and perform fixing at the corresponding positions according to the requirements of subsequent welding and forming. S4: Welding and forming The splicing fixing plate 3 moves to the welding and forming station on the fixed workbench 9, and uses the automatic welding device 7 to perform welding and forming processing on the two spliced and fixed templates. First, perform local spot welding to ensure a certain connection between the special splicing template and the conventional plastic template, then remove the fixing frame 11 on the splicing fixing plate 3, and then perform welding at all positions to ensure the integrity and service performance of the entire template. S5: Trimming and inspection After welding is completed, the welding fixing plate 6 moves to the trimming and inspection station through the fixed workbench 9 to trim the welded and formed plastic template, remove the excess weld beads on the connection surface and the forming surface, etc., to ensure the smoothness of the entire template. At the same time, use inspection tools to detect and confirm the angles and welding integrity of the universal internal corner template to ensure that the template meets the usage requirements.

[0022] Furthermore, there are two moving workbenches 1, which are symmetrically distributed about the center line of the fixed workbench 9. The fixed workbench 9 is located above the moving workbenches 1. The two moving workbenches 1 are respectively connected with a conventional plastic template fixing fixture 2 and a splicing special template fixing fixture 4. Both the splicing fixing plate 3 and the welding fixing plate 6 are connected with a positioning assembly 10. The positioning assembly 10 includes an adjusting screw 101 and a fixing block 102. The fixing block 102 is fixedly connected with the side wall of the welding fixing plate 6. The outer wall of the adjusting screw 101 is threadedly connected with the fixing block 102. One end of the adjusting screw 101 is rotatably connected with a connecting block 103.

[0023] The splicing of the template by the whole equipment: The moving workbench 1 stably conveys the conventional plastic template fixing fixture 2 and the splicing special template fixing fixture 4 through the slide rails respectively. During the processing, the conventional plastic template and the splicing special template are fixed by the conventional plastic template fixing fixture 2 and the splicing special template fixing fixture 4 respectively, and are conveyed to the directly below of the corresponding shaping processing equipment 5. The shaping processing equipment 5 can adopt a cutting machine or a milling machine to shape the template to be processed. This process is the prior art, so the specific operation process will not be described in detail. Subsequently, the processed conventional plastic template and the splicing special template are spliced and fixed, and are spliced and formed on the splicing fixing plate 3 according to the forming requirements of the universal internal corner plastic template. Then, according to the requirements of subsequent welding forming, the corresponding positions are fixed, and then it is conveyed to the below of the automatic welding equipment 7. After being welded by the welding head 71, it is trimmed and detected to complete the whole processing process. And the movement between each fixture and the plate and the moving workbench 1 and the fixed workbench 9 is the prior art, and the specific process will not be described.

[0024] Refer to Figures 5-7 , furthermore; The positioning assembly 10 further includes a limit top plate 104. A convex block 1041 is fixedly connected to the side wall of the limit top plate 104. The convex block 1041 is hinged with the connecting block 103. A cavity 1042 is opened inside the limit top plate 104. A plurality of exhaust holes 107 distributed in a linear array are opened on the side wall of the limit top plate 104. The exhaust holes 107 are communicated with the cavity 1042. A groove 113 is opened on the inner wall of one end of the cavity 1042. An airbag 110 is fixedly connected to the inner wall of the cavity 1042. One end of the airbag 110 far away from the exhaust holes 107 is fixedly connected with a pressure switch 111. An electric heating grid 109 is fixedly connected to the inside of the cavity 1042. The electric heating grid 109 is located on one side of the exhaust holes 107.

[0025] Positioning and preheating treatment of the template by the limit top plate 104: During the process of splicing the template, the limit top plate 104 can be driven to move on one side of the fixed block 102 by rotating the adjusting screw 101. At the same time, through the hinge between the connecting block 103 and the convex block 1041, and by rotating the adjusting screw 101 to different degrees, the clamping angle of the limit top plate 104 can be changed, so that it can be adjusted and positioned according to templates with different inclination angles, improving the applicability and being simple and convenient to operate. Moreover, through the action of multiple limit top plates 104, the template can be fixed in multiple directions, avoiding offset and shaking during the processing, thereby improving the welding quality. In addition, before welding, it is positioned by splicing the fixing plate 3. After moving under the automatic welding equipment 7, first start the automatic welding equipment 7 to drive the welding head 71 to perform spot welding on the template locally to ensure a certain connection strength between the two templates. Then, the fixing frame 11 is disassembled. Since the fixing frame 11 and the splicing fixing plate 3 are fixed by bolts, it can be quickly disassembled and installed, which is convenient for operation. At this time, the splicing fixing plate 3 is transformed into the welding fixing plate 6, and the automatic welding equipment 7 is a prior art. The specific automatic welding process can be controlled by external programming; In addition, before local spot welding or actual welding, start the electric heating grid 109 through an external controller. The generated heat is transmitted to the surface of the template through the exhaust holes 107. After heating for a period of time, the temperature of the spliced template can be effectively increased, so that the limit top plate 104 can not only achieve positioning but also preheat the template. Preheating increases the overall temperature of the template, reduces the temperature difference between the weld and the base metal. During welding, the thermal expansion and contraction of each part are relatively uniform, which can effectively reduce the welding stress and deformation degree. For example, in the welding of large steel structure templates, preheating can avoid deformation problems such as twisting and warping caused by stress concentration, ensure the dimensional accuracy of the template, and appropriate preheating can reduce the cooling speed of the molten pool, contribute to the escape of gas, and reduce the formation of pores; at the same time, make the solidification process of the weld metal more stable, reduce the probability of crack generation. For example, when welding quenched steel templates, preheating can avoid the generation of hardened structures and cracks due to rapid cooling, improve the welding quality, reduce the rejection rate, and save production costs; During the welding process, continuous preheating can be maintained. Continuous preheating can ensure that the weld is completed within a suitable temperature range for crystallization and solidification, reduce the adverse effects of thermal stress, and improve the welding quality. However, in actual operation, it is necessary to accurately control the preheating temperature and keep it stable. The temperature of the plate can be monitored in real time with the help of temperature monitoring equipment. According to welding process requirements and factors such as the material and thickness of the plate, the preheating temperature can be maintained within the specified range by adjusting the power of the heating equipment and other means, ensuring the smooth progress of the welding process and the stable and reliable welding quality.

[0026] Example 2, refer to Figures 7-12, Further, the positioning assembly 10 further includes a motor 105 and a rotating disk 115. The rotating disk 115 is located inside the groove 113. The motor 105 is fixedly connected to the side wall of the limiting top plate 104. One end of the motor 105 penetrates through the inner wall of the groove 113 and is fixedly connected to the side wall of the rotating disk 115. A pressing plate 114 is fixedly connected to the end of the rotating disk 115 away from the motor 105. There are two pressing plates 114, and the two pressing plates 114 are symmetrically distributed about the central axis of the rotating disk 115. The pressing plate 114 is arc-shaped; the positioning assembly 10 further includes an extension cylinder 106. The extension cylinder 106 is fixedly connected to the side wall of the limiting top plate 104. A knocking rod 108, a limiting ring 116, and a return spring 117 are arranged inside the extension cylinder 106. The outer diameter of the knocking rod 108 is smaller than the middle inner diameter of the exhaust hole 107. The limiting ring 116 is fixedly sleeved on the outer wall of one end of the knocking rod 108; the limiting ring 116 is slidably connected to the inner wall of the extension cylinder 106. An activity rod 112 is fixedly connected to the outer wall of the limiting ring 116. The activity rod 112 is in an "L" shape and is slidably connected to the inner wall of the extension cylinder 106; a column 1121 is fixedly connected to the side wall of one end of the activity rod 112. The column 1121 is slidably connected to the pressing plate 114. One side of the limiting ring 116 is fixedly connected to one end of the return spring 117. The other end of the return spring 117 is fixedly connected to the end of the extension cylinder 106 away from the limiting top plate 104.

[0027] The knocking vibration of the positioning component 10 on the welded part: In the initial state, the inside of the airbag 110 is filled with inert gas, such as helium, nitrogen, etc., which can be selected according to specific circumstances. During the preheating process of the template, as the temperature rises, it will cause the airbag 110 to expand. Eventually, the pressure switch 111 at one end of the airbag 110 will come into contact with the inner wall of the cavity 1042. And the pressure switch 111 is electrically connected to the motor 105. Therefore, after the pressure switch 111 is squeezed, the motor 105 can be made to work, and at the same time, the automatic welding equipment 7 is started for welding, thereby driving the rotating disk 115 to rotate. While the rotating disk 115 is rotating, the arc surface on one side of the pressing plate 114 presses against the column 1121. Then, through the movable rod 112, the limiting ring 116 compresses the return spring 117, and at the same time drives the knocking rod 108 to move towards the extension cylinder 106 side. And in the initial state, one end of the knocking rod 108 is located outside the limiting top plate 104. Therefore, elastic potential energy is generated by the compression of the return spring 117. As the rotating disk 115 continues to rotate, when the column 1121 and the pressing plate 114 are separated from each other, due to the setting of the flat surface at one end of the pressing plate 114, when the column 1121 loses the limit of the pressing plate 114, the elastic recovery of the return spring 117 will quickly drive the knocking rod 108 to reset, thus realizing the knocking on the surface of the template to produce a vibration effect. And this knocking structure can be set to be single or multiple according to specific circumstances. Through the cyclic rotation of the two pressing plates 114, the knocking rod 108 can be driven to reciprocate to realize the reciprocating knocking vibration of the template. The knocking vibration can make the weld and the surrounding metal produce small plastic deformation, promote the redistribution of stress, reduce the peak value of residual stress, effectively reduce the problems caused by stress concentration, improve the dimensional stability and structural strength of the template. And appropriate knocking vibration can be used as an input of mechanical vibration energy to interfere with the crystal growth process of the weld metal, so that the grains are hindered during the growth process, thereby refining the grain structure and improving the mechanical properties of the weld metal, such as increasing strength, toughness and plasticity, enhancing the reliability of the template welding joint and prolonging the service life of the template. In addition, the knocking rod 108 should be selected with a suitable knocking tool, such as a small hammer with a round head, etc., and avoid using sharp or too hard tools to prevent damage to the weld and the surface of the base material. The knocking force should be moderate and uniform. Too light may not achieve the expected effect, and too heavy may cause the weld to deform, crack or cause plastic deformation of the base material, affecting the dimensional accuracy and structural strength of the template. For example, for a template with a relatively thin thickness, the knocking force should be gentler, while for a thicker template, the force can be appropriately increased, but still needs to be controlled within a reasonable range. In addition, the knocking frequency also needs to be reasonably controlled. Too frequent knocking may overly disturb the weld metal, affecting its crystal growth process and mechanical properties;If the frequency is too low, it may not be able to effectively eliminate stress and promote gas discharge. The speed of the motor 105 can be controlled by an external speed governor to achieve knocking at an appropriate frequency, and the knocking position can also be adjusted according to the actual situation. Finally, after welding is completed, the automatic welding device 7 and the electric heating grid 109 can be turned off, and the airbag 110 can be reset by self-cooling through temperature, waiting for the next use.;

[0028] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specification of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
