Description

Technical Field

[0001] This application relates to the field of die assembly, and particularly to a balanced force application device for automobile forging die assembly. Background Art

[0002] When assembling an automobile forging die, if there is a certain deviation, it will cause uneven force on the die. Continuing to apply force in this case will damage the die. However, in the prior art, there is a lack of judgment on the uniformity of force. When applying force during assembly, it is difficult to determine whether the die is deviated and whether there is uneven force.

[0003] Therefore, there is an urgent need to provide a force application device that can display in real time whether the die is deviated and whether there is uneven force during assembly. Summary of the Invention

[0004] The purpose of this application is to be able to display in time whether the force on the forging die is balanced during assembly, thereby reducing the damage caused to the die due to uneven force application. Compared with the prior art, a balanced force application device for automobile forging die assembly is provided, including a bottom plate. A plurality of support rods are fixedly connected to the upper end of the bottom plate. The upper ends of the plurality of support rods are fixedly connected to a top plate. A control box is fixedly connected to the lower end of the top plate. An electric push rod is installed at the lower end of the control box. The extended end of the electric push rod is fixedly connected to a force verification cylinder. The forging die is placed on the bottom plate and is located directly below the force verification cylinder. A high-definition camera is installed at the inner top end of the force verification cylinder. A limiting ring is fixedly connected to the inner wall of the force verification cylinder. A force verification plate is also slidably connected to the inner wall of the force verification cylinder. An elastic telescopic rod is connected between the force verification plate and the inner top end of the force verification cylinder, and the force verification plate is located below the limiting ring. A force verification vertical ring is in interference fit below the force verification cylinder. The force verification vertical ring is located below the force verification plate and does not contact the force verification plate.

[0005] Through the setting of the force verification vertical ring, when applying force, first apply force slowly. At this time, the force verification vertical ring gradually moves towards the inside of the force verification cylinder. When the force application is uniform, a plurality of uniformly distributed light-emitting points will be displayed on the force verification plate. When there is an uneven force application situation, the extrusion between the ends of the plurality of force verification bars and the force verification plate is not synchronous, resulting in a time difference in the formation of a plurality of light-emitting points on the force verification plate and they cannot be formed synchronously. According to this phenomenon, the staff can timely judge whether the force application during assembly is balanced. When there is an uneven force application situation, the staff can detect it in time. Compared with the prior art, the damage caused to the die due to uneven force application is greatly reduced.

[0006] Furthermore, the lower end of the force verification vertical ring extends to the outside of the force verification cylinder, and the thickness of the force verification vertical ring outside the force verification cylinder is the same as the interval between the limit ring and the force verification plate. When applying force, the force verification vertical ring can just be inserted into the force verification cylinder, making the lower end face of the force verification cylinder form a horizontal plane, which is convenient for continuous force application and assembly. During the force application process, the process of the lower end part of the force verification vertical ring completely entering the force verification cylinder is a process of tentative force application. During assembly, first slowly apply force to make the force verification vertical ring enter the force verification cylinder. During this process, according to the light emission situation at the end of the force verification strip, it is possible to judge whether the partial force on the mold is balanced before the formal force application and assembly.

[0007] Furthermore, the force verification plate is a hard and transparent structure, and the part of the force verification cylinder above the limit ring is a transparent structure, which is convenient for light transmission, enabling the high-definition camera to more clearly capture the situation at the end of the force verification strip. At the same time, it is convenient for the staff to observe the situation at the end of the internal force verification strip from the outside. The part of the force verification cylinder below the limit ring is a non-transparent structure, making the space where the force verification strip is located relatively dark, making the light spot phenomenon presented on the force verification plate more obvious after the force verification strip is squeezed and contacts to emit light.

[0008] Furthermore, the force verification vertical ring includes a convex layer with an end extending below the force verification cylinder, a strip bundling plate located inside the force verification cylinder, and a plurality of force verification strips fixedly penetrating the strip bundling plate. The lower end part of the force verification strip is fixedly connected to the convex layer. Both the convex layer and the strip bundling plate are elastic structures, so that the force verification strips corresponding to the places with larger force also receive larger force. At this time, the corresponding convex layer and strip bundling plate will undergo a certain deformation, making their extrusion contact force with the force verification plate greater and more likely to emit light in advance. Furthermore, it effectively ensures that there is a time gap before and after the light emission phenomena of multiple force verification strips when the force is uneven, and both of them are in interference fit with the inner wall of the force verification cylinder.

[0009] Furthermore, the force verification strip includes a force verification hard rod fixedly penetrating the strip bundling plate, a light-transmitting hemisphere fixedly connected to the upper end of the force verification hard rod, and a force verification head fixedly connected to the upper end of the light-transmitting hemisphere. A light-transmitting hole and a sunken spherical groove are drilled in the middle of the light-transmitting hemisphere. The sunken spherical groove is located above the convex layer and the two are interconnected. When being squeezed, the force verification head deforms and enters the sunken spherical groove and makes extrusion contact with the bottom end inside the sunken spherical groove, making the middle of the force verification head emit light. Since the middle of it is embedded in the light-transmitting hemisphere, part of the light seeps into the interior of the light-transmitting hemisphere along the light-transmitting hole, and part of the light directly passes through the light-transmitting hemisphere, making the light emission phenomenon more obvious.

[0010] Further, the force - detecting head includes a force - actuated light sphere located directly above the concave spherical groove, and a ball - lifting cover fixedly connected between the outer end of the force - actuated light sphere and the light - transmitting hemisphere. The force - detecting head cover is arranged outside the concave spherical groove. In the initial state, the force - actuated light sphere does not contact the inner wall of the concave spherical groove. After being subjected to force, a certain force is required to deform the ball - lifting cover so that the force - actuated light sphere can enter the concave spherical groove and make extrusion contact with it, providing a certain space for the process of probing the applied force. The connection between the ball - lifting cover and the force - actuated light sphere is located above the center point of the force - actuated light sphere. The force - actuated light sphere is made of a force - induced luminescence material, so that it can emit light after contacting the concave spherical groove, and whether the applied force is balanced can be judged according to the luminescence conditions at the ends of multiple force - detecting strips.

[0011] Further, a tangent plane is set at the top of the light - transmitting hemisphere. The force - actuated light sphere includes two light - storing hemispheres and an outer - extension ring layer connected between the edges of the two light - storing hemispheres. A plurality of positioning rods are fixedly connected between the mutually - approaching end faces of the two light - storing hemispheres, and the positioning rods are located inside the outer - extension ring layer.

[0012] Further, the light - storing hemispheres are filled with fluorescent liquid. The hemispherical surface of the light - storing hemisphere is a flexible non - transparent sealed structure, the flat surface of the light - storing hemisphere is a hard porous structure, and the outer - extension ring layer is an elastic transparent sealed structure. When applying force, the ball - lifting cover deforms first, and then the bottom of the force - actuated light sphere makes extrusion contact with the upper plane of the light - transmitting hemisphere. As the force continues to be applied, the two light - storing hemispheres deform, causing the fluorescent liquid to gather in the middle, making the outer - extension ring layer bulge and deform outward, and then leaking out of the light - storing hemisphere, so that the light of the fluorescent liquid can penetrate through the force - detecting plate, and obvious light changes at the force - detecting strip can be photographed by the high - definition camera, which can also achieve the above - mentioned display effect of the balance of the applied force.

[0013] Compared with the prior art, the advantages of this application are as follows:

[0014] (1) Through the setting of the force - detecting vertical ring, when applying force, first apply force slowly. At this time, the force - detecting vertical ring gradually moves towards the inside of the force - detecting cylinder. When the applied force is uniform, a plurality of uniformly - distributed light - emitting points will be displayed on the force - detecting plate. When there is an uneven applied force, the extrusion between the ends of the multiple force - detecting strips and the force - detecting plate is out of sync, resulting in a time difference in the formation of multiple light - emitting points on the force - detecting plate and they cannot be formed synchronously. According to this phenomenon, the staff can timely judge whether the applied force during assembly is balanced. When the applied force is unbalanced, the staff can be aware of it in time. Compared with the prior art, the damage to the mold caused by uneven applied force is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0026] Embodiment 1:

[0027] The present application discloses a device for applying balanced force in the assembly of an automotive forging die. Please refer to Figure 1 , where a in the figure represents the die, including a base plate 1. A plurality of support rods 3 are fixedly connected to the upper end of the base plate 1. A top plate 2 is fixedly connected to the upper ends of the plurality of support rods 3. A control box is fixedly connected to the lower end of the top plate 2. An electric push rod 4 is installed at the lower end of the control box. The extended end of the electric push rod 4 is fixedly connected to a force verification cylinder 5. The forging die is placed on the base plate 1 and is located directly below the force verification cylinder 5.

[0028] Please refer to Figure 2, a high-definition camera 10 is installed at the top end inside the force verification cylinder 5. A limiting ring 61 is fixedly connected to the inner wall of the force verification cylinder 5. A force verification plate 62 is also slidably connected to the inner wall of the force verification cylinder 5. An elastic telescopic rod is connected between the force verification plate 62 and the top end inside the force verification cylinder 5. And the force verification plate 62 is located below the limiting ring 61. An interference fit is provided between the lower part of the force verification cylinder 5 and a vertical force verification ring which is located below the force verification plate 62 and whose point does not come into contact with the force verification plate 62.

[0029] The lower end of the vertical force verification ring extends to the outside of the force verification cylinder 5, and the thickness of the vertical force verification ring outside the force verification cylinder 5 is the same as the interval between the limiting ring 61 and the force verification plate 62. So that during the application of force, the vertical force verification ring can just be inserted into the force verification cylinder 5, making the lower end face of the force verification cylinder 5 form a horizontal plane, which is convenient for continuous force application and assembly. During the force application process, the process of the lower end part of the vertical force verification ring completely entering into the force verification cylinder 5 is a process of tentative force application. During assembly, first apply force slowly to make the vertical force verification ring enter the force verification cylinder 5. During this process, according to the light-emitting situation of the end part of the force verification strip 8, it can be judged whether the partial force on the mold is balanced before the formal force application and assembly; the force verification plate 62 is a hard and transparent structure, and the part of the force verification cylinder 5 above the limiting ring 61 is a transparent structure, which is convenient for light transmission, enabling the high-definition camera 10 to more clearly capture the situation of the end part of the force verification strip 8, and at the same time facilitating the staff to observe the situation of the end part of the internal force verification strip 8 from the outside. The part of the force verification cylinder 5 below the limiting ring 61 is a non-transparent structure, making the space where the force verification strip 8 is located relatively dark, making the light spot phenomenon presented on the force verification plate 62 more obvious after it is squeezed and contacts with the force verification plate 62 and emits light.

[0030] The vertical force verification ring includes an outer convex layer 91 whose end part extends below the force verification cylinder 5, a strip bundling plate 92 located inside the force verification cylinder 5, and a plurality of force verification strips 8 fixedly penetrating through the strip bundling plate 92. The lower end part of the force verification strip 8 is fixedly connected to the outer convex layer 91. Both the outer convex layer 91 and the strip bundling plate 92 are elastic structures, so that the force verification strips 8 corresponding to the parts with larger force receive the same large force. At this time, the corresponding outer convex layer 91 and strip bundling plate 92 will undergo a certain deformation accordingly, making their extrusion contact force with the force verification plate 62 larger and more likely to emit light in advance. Furthermore, it effectively ensures that there is a time gap before and after the light-emitting phenomena of multiple force verification strips 8 when the force is uneven, and both of them have an interference fit with the inner wall of the force verification cylinder 5.

[0031] Please refer to Figure 3, the force testing strip 8 includes a force testing rigid rod 81 fixedly passing through the strip plate 92, a light-transmitting hemispherical body 82 fixedly connected to the upper end of the force testing rigid rod 81, and a force testing head 83 fixedly connected to the upper end of the light-transmitting hemispherical body 82. A light-transmitting hole 71 and a sunken spherical groove 72 are formed in the middle of the light-transmitting hemispherical body 82. The sunken spherical groove 72 is located above the convex layer 91 and the two are interconnected. When being squeezed, the force testing head 83 deforms and enters the sunken spherical groove 72 and makes extrusion contact with the inner bottom end of the sunken spherical groove 72, causing the middle part of the force testing head 83 to emit light. Since the middle part of it is embedded in the light-transmitting hemispherical body 82, part of the light seeps into the interior of the light-transmitting hemispherical body 82 along the light-transmitting hole 71, and part of the light directly passes through the light-transmitting hemispherical body 82, making the light-emitting phenomenon more obvious.

[0032] Please refer to Figure 4 , the force testing head 83 includes a force-driven light sphere 832 located directly above the sunken spherical groove 72 and a lifting sphere cover 831 fixedly connected between the outer end of the force-driven light sphere 832 and the light-transmitting hemispherical body 82. The force testing head 83 covers the outside of the sunken spherical groove 72, as Figure 5 , in the initial state, the force-driven light sphere 832 does not contact the inner wall of the sunken spherical groove 72. After being stressed, a certain force is required to make the lifting sphere cover 831 deform so that the force-driven light sphere 832 can enter the sunken spherical groove 72 and make extrusion contact with it, providing a certain space for the process of tentative force application. The connection part between the lifting sphere cover 831 and the force-driven light sphere 832 is located above the center point of the force-driven light sphere 832. The force-driven light sphere 832 is made of a force-induced light-emitting material, so that it can emit light after contacting the sunken spherical groove 72. Whether the force application is balanced can be judged according to the light-emitting conditions at the ends of multiple force testing strips 8.

[0033] Through the setting of the force testing vertical ring, when applying force, first apply force slowly. At this time, the force testing vertical ring gradually moves towards the inside of the force testing cylinder 5. When the force application is uniform, multiple uniformly distributed light-emitting points will be displayed on the force testing plate 62. When there is an uneven force application situation, the extrusion between the ends of multiple force testing strips 8 and the force testing plate 62 is out of sync, resulting in a time difference among the multiple light-emitting points formed on the force testing plate 62 and they cannot be formed synchronously. According to this phenomenon, the staff can timely judge whether the force application during assembly is balanced. When an uneven force application situation occurs, the staff can be aware of it in time. Compared with the prior art, the damage to the mold caused by uneven force application is greatly reduced.

[0034] Embodiment 2:

[0035] Please refer to Figures 7-8, a tangent plane is set at the top of the light-transmitting hemisphere 82. The force-actuating light sphere 832 includes two light-storing hemispheres 8322 and an outer extension ring layer 8321 connected between the edges of the two light-storing hemispheres 8322. A plurality of positioning rods 9 are fixedly connected between the end faces of the two light-storing hemispheres 8322 that are close to each other. The positioning rods 9 are located inside the outer extension ring layer 8321. The light-storing hemispheres 8322 are filled with fluorescent liquid. The hemispherical surface of the light-storing hemisphere 8322 is a flexible non-transparent sealing structure, and the flat surface of the light-storing hemisphere 8322 is a hard porous structure. The outer extension ring layer 8321 is an elastic transparent sealing structure. When applying force, the lifting ball cover 831 deforms first, and then the bottom of the force-actuating light sphere 832 squeezes and contacts the upper plane of the light-transmitting hemisphere 82. As the force continues to be applied, the two light-storing hemispheres 8322 deform, and the fluorescent liquid gathers in the middle, causing the outer extension ring layer 8321 to bulge and deform outward, and then the light-storing hemispheres 8322 are leaked out, so that the light of the fluorescent liquid can penetrate at the force-testing plate 62, and the high-definition camera 10 can capture obvious light changes at the force-testing strip 8, and the same display effect of force application balance can be achieved.

[0036] In addition, it is worth noting that in the above two embodiments, a data processing module is integrated in the control box, which can process and identify the pictures of the light-emitting conditions of the ends of multiple force-testing strips 8 captured by the high-definition camera 10. Correspondingly, an alarm or a signal lamp can be installed on the control box. When there is a situation where the ends of multiple force-testing strips 8 do not light up simultaneously, it can alarm or light up the signal lamp in real time, effectively avoiding damage to the mold caused by uneven force application.

[0037] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its improvement concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
