Description
Technical Field
[0001] The utility model relates to the technical field of hemming equipment, in particular to an automobile engine hood hemming equipment. Background Art
[0002] Car hood hemming equipment is a professional equipment used in the automobile manufacturing industry. It is mainly used for edge processing of car hoods. This equipment can bend metal sheets into specific shapes to meet the requirements of car design.
[0003] The existing hemming equipment consists of an upper die base and a lower die base. The lower die base is used to place a cavity of the required shape, and pressure is applied through the upper die base for processing. However, the requirements for the edge of the car hood are inconsistent, which leads to the need for personnel to frequently replace the cavity during the processing. Currently, most cavities are fixed by bolts. When replacing them, personnel need to use special tools to disassemble them, which is inconvenient to operate and difficult to increase the replacement rate. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides an automobile engine hood hemming device.
[0005] The utility model is implemented by the following technical scheme: an automobile engine hood hemming device, comprising a side frame, one side of the side frame is fixedly connected to a preset table, the middle of the inner walls on both sides of the preset table are provided with a first slide groove, and the interior of the first slide groove is slidably connected to a cavity assembly;
[0006] The cavity assembly includes a first slider, one side of which is fixedly connected to a lower mold seat, the lower mold seat is slidably connected to the inner wall of the preset table through the first slider, a cavity is opened on the upper surface of the lower mold seat, and an operating handle is fixedly connected to the middle of the front side of the lower mold seat.
[0007] Through the above technical solution, when the lower mold seat slides inside the preset table, due to the setting of the first slider, the lower mold seat can be clamped on the inner wall of the preset table, which improves the stability of the lower mold seat during operation and avoids the problem of displacement and shaking. In addition, personnel can quickly pull out the lower mold seat through the operating handle and change the shape of the cavity in time according to actual work needs, thereby ensuring that the edge of the processed hood meets the standards, reducing the time required for personnel to replace the mold, and the disassembly and assembly are simple and convenient.
[0008] As a further improvement of the above solution, a placement table is fixedly connected to the bottom of the side frame, and assembly grooves are provided at the four corners of the upper surface of the placement table.
[0009] Through the above technical solution, the setting of the placement table can improve the stability of the device during operation and avoid the problem of tilting and shaking of the device.
[0010] As a further improvement of the above solution, a damping spring is fixedly connected inside the assembly groove, and the top end of the damping spring is fixedly connected to the lower surface of the preset table.
[0011] Through the above technical solution, the shock-absorbing spring can alleviate the pressure exerted by the upper mold block on the lower mold seat during operation, avoiding the pressure from directly acting on the surface of the lower mold seat. Long-term use may easily cause the lower mold seat to lose rigidity and reduce its service life.
[0012] As a further improvement of the above solution, a second sliding groove is provided on the surface of the side frame, and a second sliding block is slidably connected inside the second sliding groove.
[0013] Through the above technical solution, the second slider slides inside the second slide groove to limit the upper mold block, thereby preventing the upper mold block from shaking, tilting, and deviating from the motion trajectory during the lifting process.
[0014] As a further improvement of the above solution, an upper mold block is fixedly connected to one side of the second sliding block, and the upper mold block is slidably connected to the surface of the side frame through the second sliding block.
[0015] Through the above technical solution, when the upper mold block moves downward, pressure can be applied to the placed engine hood to make it contact with the lower mold seat at the bottom, thereby processing the engine hood and making it into a desired shape.
[0016] As a further improvement of the above solution, a connecting plate is fixedly connected to the top of the side frame, and an outer protective shell is fixedly connected to the middle part of the upper surface of the connecting plate.
[0017] Through the above technical solution, the outer protective shell can protect the internal hydraulic motor to prevent the hydraulic motor from being exposed to the outside and being easily hit and bumped by external objects, causing the surface to be easily damaged and increasing subsequent maintenance costs.
[0018] As a further improvement of the above scheme, a hydraulic motor is arranged inside the outer protective shell, the output end of the hydraulic motor is fixedly connected to a threaded rod, the bottom end of the threaded rod is threadedly connected to a sleeve, and the bottom end of the sleeve is fixedly connected to the upper surface of the upper mold block.
[0019] Through the above technical scheme, the hydraulic motor can generate a rotational force, and the hydraulic motor transmits the rotational force to the threaded rod through the output end. The threaded rod rotates, and the sleeve is extended and retracted through the internal thread, thereby adjusting the height of the upper mold block. When the upper mold block descends, pressure can be applied to the placed hood, so that the hood and the lower mold seat at the bottom come into contact, thereby processing the hood.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] The utility model arranges a cavity assembly, and when the lower mold seat is assembled inside the preset table, due to the arrangement of the first slider, the lower mold seat can be clamped on the inner wall of the preset table, thereby improving the stability of the lower mold seat during operation, and personnel can quickly pull out the lower mold seat through an operating handle, and timely change the shape of the cavity according to actual work needs, thereby ensuring that the edge of the machined engine hood meets the standards and reducing the time required for personnel to replace the mold, and the shock-absorbing spring can relieve the pressure exerted by the upper mold block on the lower mold seat, avoiding the pressure directly acting on the surface of the lower mold seat, which is likely to cause the problem of reduced structural rigidity.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0030] Example:
[0031] Please combine Figure 1-5 The present embodiment is a car hood hemming device, comprising a side frame 1, one side of the side frame 1 is fixedly connected to a preset table 2, the middle of the inner walls of both sides of the preset table 2 are provided with a first slide groove 3, and the interior of the first slide groove 3 is slidably connected to a cavity assembly 4;
[0032] The cavity assembly 4 includes a first slider 401, one side of which is fixedly connected to a lower mold base 402, which is slidably connected to the inner wall of the preset table 2 through the first slider 401, and a cavity 403 is provided on the upper surface of the lower mold base 402, and an operating handle 404 is fixedly connected to the middle of the front side of the lower mold base 402. When the lower mold base 402 slides inside the preset table 2, due to the setting of the first slider 401, the lower mold base 402 can be clamped on the inner wall of the preset table 2, which improves the stability of the lower mold base 402 during operation and avoids the problem of displacement and shaking. In addition, personnel can quickly pull out the lower mold base 402 through the operating handle 404, and timely change the shape of the cavity 403 according to actual work requirements, thereby ensuring that the edge of the processed hood meets the standards, reducing the time required for personnel to replace the mold, and the disassembly and assembly are simple and convenient.
[0033] The bottom of the side frame 1 is fixedly connected with a placing table 5, and the four corners of the upper surface of the placing table 5 are provided with assembly grooves 6. The setting of the placing table 5 can improve the stability of the device during operation and avoid the problem of tilting and shaking of the device.
[0034] A damping spring 7 is fixedly connected inside the assembly groove 6, and the top end of the damping spring 7 is fixedly connected to the lower surface of the preset table 2. The damping spring 7 can alleviate the pressure exerted by the upper mold block 10 on the lower mold seat 402 during operation, avoiding the pressure from directly acting on the surface of the lower mold seat 402. Long-term use may easily cause the lower mold seat 402 to lose rigidity and reduce its service life.
[0035] A second slide groove 8 is provided on the surface of the side frame 1, and a second slider 9 is slidably connected inside the second slide groove 8. The second slider 9 slides inside the second slide groove 8 to limit the upper mold block 10, thereby preventing the upper mold block 10 from shaking, tilting, and deviating from the motion trajectory during the lifting process.
[0036] An upper mold block 10 is fixedly connected to one side of the second slider 9, and the upper mold block 10 is slidably connected to the surface of the side frame 1 through the second slider 9. When the upper mold block 10 moves downward, it can apply pressure to the placed engine hood to make it contact with the lower mold seat 402 at the bottom, thereby processing the engine hood and making it into a desired shape.
[0037] A connecting plate 11 is fixedly connected to the top of the side frame 1, and an outer protective shell 12 is fixedly connected to the middle of the upper surface of the connecting plate 11. The outer protective shell 12 can protect the internal hydraulic motor 13 to prevent the hydraulic motor 13 from being exposed to the outside and being easily hit and bumped by external objects, resulting in the problem of surface damage and increased subsequent maintenance costs.
[0038] A hydraulic motor 13 is arranged inside the outer protective shell 12, and a threaded rod 14 is fixedly connected to the output end of the hydraulic motor 13, and a sleeve 15 is threadedly connected to the bottom end of the threaded rod 14, and the bottom end of the sleeve 15 is fixedly connected to the upper surface of the upper mold block 10. The hydraulic motor 13 can generate a rotational force, and the hydraulic motor 13 transmits the rotational force to the threaded rod 14 through the output end. The threaded rod 14 rotates, and the sleeve 15 is extended and retracted through the internal thread, thereby adjusting the height of the upper mold block 10. When the upper mold block 10 descends, pressure can be applied to the placed hood, so that the hood and the lower mold seat 402 at the bottom come into contact, thereby processing the hood.
[0039] The implementation principle of an automobile engine hood hemming device in the embodiment of the present application is as follows: when the lower mold base 402 is assembled inside the preset table 2, due to the setting of the first slider 401, the lower mold base 402 can be clamped on the inner wall of the preset table 2, which improves the stability of the lower mold base 402 during operation and avoids the problem of displacement and shaking. In addition, the personnel can quickly pull out the lower mold base 402 through the operating handle 404, and timely change the shape of the cavity 403 according to actual work needs, thereby ensuring that the processed engine hood edge meets the standard, reducing the time required for personnel to replace the mold, and the disassembly and assembly are simple and convenient, which is convenient for personnel to operate, and then the personnel start the hydraulic motor 1 3. The hydraulic motor 13 can generate a rotational force, and the hydraulic motor 13 transmits the rotational force to the threaded rod 14 through the output end. The threaded rod 14 rotates, and the sleeve 15 is extended and retracted through the internal thread, so as to adjust the height of the upper mold block 10. When the upper mold block 10 descends, pressure can be applied to the placed engine cover, so that the engine cover and the lower mold seat 402 at the bottom come into contact, so as to process the engine cover. The shock-absorbing spring 7 can relieve the pressure applied by the upper mold block 10 to the lower mold seat 402 during operation, and avoid the pressure directly acting on the surface of the lower mold seat 402. Long-term use can easily cause the lower mold seat 402 to have a reduced rigidity and a reduced service life.
