Description

Technical Field

[0001] This utility model belongs to the field of bumper repair technology, and in particular relates to a multi-station shaping device for bumper repair. Background Technology

[0002] Bumper repair and restoration is a repair technique for car bumpers damaged by collisions, scrapes, stone impacts, etc., resulting in deformation, dents, cracks, scratches, etc. It uses professional processes such as physical shaping (heating, stretching, pressing), chemical repair (filling, polishing, painting), and structural alignment to restore the original shape, appearance, and safety functions of the bumper. The core of bumper repair is restoration, not replacement. The process must be tailored to the bumper material (currently, thermoplastic is the mainstream, with some older cars using metal or composite materials). For example, plastic bumpers often use the "thermal repair method" (using the softening properties of plastic to reshape it), metal bumpers may combine welding and sheet metal alignment, and composite materials require special adhesives and polishing.

[0003] A search revealed a Chinese patent website that discloses a shaping bracket for remanufacturing car bumpers, with publication number CN214724016U. In use, the first motor is started to move the clamping frame to its lowest point. The bumper to be repaired is placed on top of the base, and the bumper is manually placed on the inner surface of the clamping frame. This causes the rotating plate to rotate, simultaneously rotating the bumper on the clamping frame. This saves repair personnel the time and effort of walking back and forth to see the other side of the bumper, thus speeding up the repair process. However, some defects and shortcomings exist and need improvement: (1) Most existing repair and shaping devices use a single-station design. The design of bumpers is often complicated by their length. When different parts of the bumper need to be repaired and reshaped, the position of the bumper needs to be moved frequently and then repositioned. This is not only tedious and inconvenient, but the frequent movement and disassembly can also damage the bumper. (2) Some existing repair and reshaping devices usually use clamps to hold and fix the bumper to prevent it from shifting during the repair and reshaping process. However, the existing clamp structures are often only suitable for bumpers of specific shapes. They are not effective for bumpers with complex curved surfaces, which will affect the repair and reshaping accuracy of the bumper. Therefore, in view of the above problems, the multi-station reshaping device for bumper repair provided by this utility model is of great significance. Utility Model Content

[0004] This invention provides a multi-station shaping device for bumper repair. The shaping mechanism utilizes shaping equipment installed in the workstation slots to repair and shape the bumper. Multiple shaping devices can be installed simultaneously in multiple equidistant linearly distributed workstation slots, enabling multi-station bumper repair and shaping. When different parts of the bumper need repair and shaping, the shaping equipment in the corresponding workstation slot is activated and operated, eliminating the need to move the bumper. This significantly improves overall work efficiency and avoids damage to the bumper caused by frequent movement and disassembly. The positioning component clamps and fixes the bumper in place. The rubber blocks in the positioning component are elastic. When they come into contact with the surface of the bumper, they undergo elastic deformation due to compression. Furthermore, for bumpers with complex curved surfaces, the amount of elastic deformation of each rubber block will vary. This allows the positioning component to effectively clamp bumpers of different shapes, which not only improves the applicability of the positioning component but also ensures the repair and shaping accuracy of the bumper. In addition, the bumper can be firmly adsorbed onto the shaping table through vacuum adsorption to further improve the stability of the bumper and prevent it from shifting during the repair and shaping process. In summary, this solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a multi-station shaping device for bumper repair, including a workbench, a number of support legs fixedly connected to the bottom of the workbench, a shaping table fixedly connected to the top of the workbench, brackets fixedly connected to both sides of the shaping table, positioning components provided on the brackets, a fixing frame provided above the shaping table, the bottom of the fixing frame fixedly connected to the workbench, and a shaping mechanism provided on the fixing frame.

[0007] The positioning component includes a first electric telescopic rod, which is mounted on a bracket. A positioning plate is fixedly connected to the end of its output shaft. Several fixing cylinders are fixedly connected to the side wall of the positioning plate, and a rubber block is provided inside each fixing cylinder.

[0008] The shaping mechanism includes a second electric telescopic rod, which is installed on the top of the fixed frame. The bottom end of its output shaft is fixedly connected to a mounting plate. The bottom surface of the mounting plate has several work station slots, and each work station slot has several threaded holes.

[0009] Furthermore, the workstation slots are rectangular and are equidistantly distributed linearly along the length of the mounting plate. Each workstation slot contains four threaded holes, and each threaded hole is located at one of the four corners of the workstation slot.

[0010] Furthermore, the mounting plate is located directly above the shaping table, and protrusions are fixedly connected to both sides of it. Guide rods are fixedly connected to the top of the protrusions. A pair of guide holes are opened on the top of the fixing frame. The diameter of the guide holes is equal to the diameter of the guide rods, and each guide rod passes through the corresponding guide hole.

[0011] Furthermore, the fixing cylinder is circular and is distributed linearly at equal intervals along the length of the positioning plate, and the bottom surface of the positioning plate is level with the top surface of the shaping table.

[0012] Furthermore, the cross-section of the rubber block is circular, its diameter is equal to the inner diameter of the fixing cylinder, its length is greater than the length of the fixing cylinder, and the end face of the rubber block is spherical.

[0013] Furthermore, the interior of the shaping table is a hollow structure, with an air extraction port on its side wall, and a number of adsorption holes on the top surface of the shaping table. The adsorption holes are arranged in a linear array along the top surface of the shaping table, and each adsorption hole and air extraction port is connected to the inner cavity of the shaping table.

[0014] The present invention has the following advantages over the prior art:

[0015] (1) The multi-station design allows for the repair and shaping of different parts of the bumper without moving its position: The shaping mechanism can use the shaping equipment installed in the work station slot to repair and shape the bumper. Multiple shaping equipment can be installed at the same time through multiple work station slots that are equidistantly linearly distributed, so as to realize the multi-station repair and shaping of the bumper. When different parts of the bumper need to be repaired and shaped, the shaping equipment in the corresponding work station slot can be started and operated without moving the position of the bumper. This not only greatly improves the overall work efficiency, but also avoids damage to the bumper caused by frequent movement and disassembly.

[0016] (2) It can effectively fix bumpers of different shapes, with good fixing effect and wide applicability: The positioning component can clamp and fix the bumper. The rubber block in the positioning component is elastic. When it comes into contact with the surface of the bumper, it will undergo elastic deformation due to compression. For bumpers with complex curved surfaces, the elastic deformation of each rubber block will also be different. Thus, the positioning component can effectively clamp bumpers of different shapes, which not only improves the applicability of the positioning component, but also ensures the repair and shaping accuracy of the bumper. In addition, the bumper can be firmly adsorbed on the shaping table by vacuum adsorption to further improve the stability of the bumper and prevent it from shifting during the repair and shaping process.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1-5 As shown, a multi-station shaping device for bumper repair according to this utility model includes a workbench 1, a plurality of support legs 2 fixedly connected to the bottom of the workbench 1, and a shaping table 3 fixedly connected to the top of the workbench 1. The shaping table 3 is used to place the bumper to be repaired and shaped. Brackets 4 are fixedly connected to both sides of the shaping table 3. Positioning components are provided on the brackets 4. A fixing frame 5 is provided above the shaping table 3. The bottom of the fixing frame 5 is fixedly connected to the workbench 1, and a shaping mechanism is provided on the fixing frame 5.

[0029] The positioning assembly includes a first electric telescopic rod 6, which is mounted on a bracket 4. A positioning plate 7 is fixedly connected to the end of its output shaft. Several fixing cylinders 8 are fixedly connected to the side wall of the positioning plate 7. Each fixing cylinder 8 contains a rubber block 9. By driving the first electric telescopic rod 6, the positioning plate 7 can be moved towards the bumper. When the rubber block 9 in each fixing cylinder 8 contacts the surface of the bumper, the pressure applied by the rubber block 9 can be used to clamp and fix the bumper.

[0030] The shaping mechanism includes a second electric telescopic rod 10, which is installed on the top of the fixed frame 5. The bottom end of its output shaft is fixedly connected to a mounting plate 11. The bottom surface of the mounting plate 11 has several work station slots 12, and each work station slot 12 has several threaded holes 13. Bolts and other fasteners can be screwed into the threaded holes 13 to fix the equipment required for bumper repair and shaping in the corresponding work station slot 12. The corresponding shaping equipment can be selected according to the material of the bumper. For example, a hot air gun can be installed for a plastic bumper, and a welding gun can be installed for a metal bumper. By driving the second electric telescopic rod 10, the mounting plate 11 and the shaping equipment in each work station slot 12 can be moved up and down to adjust the height of the shaping equipment as needed.

[0031] The work station slots 12 are rectangular and equidistantly distributed along the length of the mounting plate 11. Each work station slot 12 contains four threaded holes 13, located at the four corners of the work station slot 12. Multiple equidistantly distributed work station slots 12 allow for the simultaneous installation of multiple shaping devices, enabling multi-station repair and shaping of the bumper. When different parts of the bumper need repair and shaping, the shaping device in the corresponding work station slot 12 can be activated and operated without moving the bumper. This significantly improves overall work efficiency and avoids damage to the bumper caused by frequent movement and disassembly. Specifically, the dimensions of the work station slot 12 are set to 1. The 50mm×100mm×20mm (length×width×depth) base is compatible with the base size (≤140mm×90mm) of mainstream small shaping equipment (hot air gun, welding gun, small grinder) on the market. The four threaded holes 13 in each workstation slot are of M8 specification, with a hole spacing of 120mm×70mm (horizontal×vertical), which matches the common spacing of equipment base mounting holes in GB / T5277 standard, ensuring that the bolts can stably fix the equipment. There are 5-6 workstation slots 4 with a spacing of 300mm. The total length of the mounting plate 11 is 1.8-2.2m, which can cover more than 90% of the damage point distribution range of mainstream car / SUV bumpers (length 1.5-2.5m) on the market.

[0032] The mounting plate 11 is located directly above the shaping table 3, with protrusions 14 fixedly connected to both sides. Guide rods 15 are fixedly connected to the top of the protrusions 14. A pair of guide holes 16 are opened on the top of the fixing frame 5. The diameter of the guide holes 16 is equal to the diameter of the guide rods 15. Each guide rod 15 passes through the corresponding guide hole 16. When the height of the shaping equipment is adjusted, the mounting plate 11 can drive the protrusions 14 and each guide rod 15 to move up and down along the corresponding guide hole 16. At this time, the mutual cooperation between the guide rods 15 and the guide holes 16 can play a guiding and limiting role, so as to ensure that the mounting plate 11 always moves up and down in the vertical direction, thereby effectively avoiding the impact of shaking and tilting of the mounting plate 11 on the repair and shaping effect.

[0033] The fixing cylinder 8 is circular and is distributed linearly at equal intervals along the length of the positioning plate 7. The bottom surface of the positioning plate 7 is level with the top surface of the shaping table 3. Multiple rubber blocks 9 can be installed simultaneously through multiple linearly distributed fixing cylinders 8. When the bumper is clamped and fixed using the positioning assembly, the rubber blocks 9 in each fixing cylinder 8 can contact different parts of the bumper respectively, so that different parts of the bumper can be fixed without moving the position of the positioning structure.

[0034] The rubber block 9 has a circular cross-section, with its diameter equal to the inner diameter of the fixing cylinder 8. Its length is greater than the length of the fixing cylinder 8, and its end face is spherical. The rubber block 9 can be inserted into and adhered to the inner wall of the fixing cylinder 8 for fixation via a plug-in method. The rubber block 9 is elastic; when in contact with the surface of the bumper, it undergoes elastic deformation due to compression. Furthermore, for bumpers with complex curved surfaces, the amount of elastic deformation of each rubber block 9 will vary. This allows for effective clamping of bumpers of different shapes using the positioning component, not only improving the applicability of the positioning component but also ensuring the accuracy of bumper repair and reshaping. When the rubber block 9 wears down due to prolonged use, it can be removed from the fixing cylinder. 8. Pull out for quick replacement. Specifically, an annular groove is opened on the inner wall of the fixing cylinder 8, and an annular protrusion is correspondingly set on the outer wall of the rubber block 9. After the protrusion is inserted into the groove, it achieves axial limitation to prevent it from falling off. The rubber block 9 is made of heat-resistant ethylene propylene diene monomer (EPDM) rubber with a Shore hardness of A50-A60, an elastic modulus of 1.5-2MPa, and a continuous working temperature range of -40℃ to 250℃. This ensures that it is suitable for the heating and repair of plastic bumpers and avoids crushing or clamping failure. The maximum axial compression of the rubber block 9 is 15mm (compression rate ≤30% to avoid permanent deformation), and the maximum radial offset is 8mm. This allows it to adapt to the complex curved surface of the bumper with a curvature radius ≥8mm, ensuring a tight fit with the curved surface and a firm clamping.

[0035] The shaping table 3 has a hollow internal structure with an air extraction port 17 on its side wall and several adsorption holes 18 on its top surface. These adsorption holes 18 are arranged in a linear array along the top surface of the shaping table 3, and each adsorption hole 18 and the air extraction port 17 are connected to the internal cavity of the shaping table 3. An external vacuum pump can be connected to the air extraction port 17. When the bumper is placed on the shaping table 3, the internal cavity of the shaping table 3 can be evacuated through the air extraction port 17 using the external vacuum pump until a vacuum is formed inside the shaping table 3. Under this negative pressure, air is drawn from the adsorption holes 18. The bumper can be firmly attached to the shaping table 3 to further improve its stability and prevent it from shifting during the repair process. When there are cracks or holes on the surface of the bumper, a high-temperature resistant sealing gasket (made of silicone, 2mm thick) can be laid on the top surface of the shaping table 3. The sealing gasket has through holes corresponding to the adsorption holes 18 to ensure that the negative pressure only acts on the undamaged area of ​​the bumper. At the same time, temporary sealant (model 3M5200) is applied around the cracks or holes. The sealant is removed after the bumper is fixed in place to avoid air leakage affecting the adsorption effect.

[0036] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0037] The working principle of this utility model is as follows:

[0038] In use, the bumper to be repaired can be placed on the shaping table 3. Then, the first electric telescopic rod 6 is driven to move the positioning plate 7 towards the bumper until the rubber blocks 9 in each fixing cylinder 8 contact the surface of the bumper. At this point, the pressure applied by the rubber blocks 9 clamps and fixes the bumper. The rubber blocks 9 are elastic and will undergo elastic deformation due to compression when in contact with the surface of the bumper. For bumpers with complex curved surfaces, the amount of elastic deformation of each rubber block 9 will also be different. Thus, the positioning component can effectively clamp bumpers of different shapes, which not only improves the adaptability of the positioning component but also ensures the repair and shaping accuracy of the bumper. In addition, an external vacuum pump can be used to evacuate the inner cavity of the shaping table 3 through the air extraction port 17 until a vacuum is formed inside the shaping table 3. Under negative pressure, the bumper can be firmly attached to the shaping table 3 using the suction holes 18, further improving its stability. After the bumper is fixed, the second electric telescopic rod 10 can be driven to move the mounting plate 11 and the shaping equipment in each work station slot 12 up and down, so as to adjust the height of the shaping equipment as needed. Then, the bumper can be repaired and shaped using the shaping equipment. Multiple shaping equipment can be installed simultaneously through multiple work station slots 12 that are linearly distributed at equal intervals, so as to realize multi-station repair and shaping of the bumper. When different parts of the bumper need to be repaired and shaped, the shaping equipment in the corresponding work station slot 12 can be started and operated without moving the position of the bumper. This not only greatly improves the overall work efficiency, but also avoids damage to the bumper caused by frequent movement and disassembly.
