Description

Technical Field

[0001] The utility model belongs to the field of stamping equipment, and particularly relates to a stamping device with convenient replacement of the lower die. Background Art

[0002] The gasket stamping equipment is a kind of equipment specially used for stamping gasket materials. There are some disadvantages in the current gasket stamping equipment. First of all, the inconvenient replacement of the lower die is a relatively prominent problem. This shortcoming is mainly due to the unreasonable design of the equipment structure and the relatively complex die fixing method. When replacing the lower die, a large amount of time and manpower are often required for disassembly and installation operations. The usual solution is to arrange professional technicians for replacement operations, make a replacement plan in advance, and try to reduce the downtime caused by die replacement. However, this method has drawbacks. On the one hand, it increases the labor cost. The enterprise needs to pay the salary of professional technicians, and there may be operation errors due to human factors during the replacement process, affecting the normal operation of the equipment and the product quality. On the other hand, the advance plan for die replacement may be affected by changes in production tasks. If there are emergency orders or production plan adjustments, the replacement plan may be disrupted, affecting the production progress. Therefore, a new structure needs to be proposed to solve the above technical problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a stamping device with convenient replacement of the lower die, and solve the problems put forward in the above background art.

[0004] The utility model is realized through the following technical solutions: A stamping device with convenient replacement of the lower die, comprising: a base, a cover plate and a stamping seat. The stamping seat is installed on the upper surface of the base through shock absorbers. The cover plate is installed on the upper surface of the base through vertical rods. A guiding column is installed between the cover plate and the stamping seat. A movable plate is installed on the outer surface of the guiding column. An upper die is installed on the lower surface of the movable plate. The lower die is fixed on the upper surface of the stamping seat through a fixing member. The fixing member includes: a fixing block and a cylinder. The cylinder is installed on the lower surface of the stamping seat. The fixing block is movably installed above the stamping seat through the cylinder. An installation groove is opened on the upper surface of the stamping seat. A sliding groove is opened at the bottom of the installation groove inside. The lower die is clamped and fixed on the upper surface of the stamping seat through the installation groove, the fixing member and the sliding groove.

[0005] As a preferred embodiment, a shock absorber is respectively installed at each of the four corners of the upper side surface inside the base. One end of the four shock absorbers away from the base is connected to each of the four corners of the lower side surface of the stamping seat. There is a 5 cm gap between the lower side surface of the stamping seat and the base through the shock absorber. During use, during the stamping process, the stamping force will generate large vibrations, and the shock absorbers can effectively absorb and reduce these vibrations, keeping the stamping seat relatively stable, which helps to improve the stamping accuracy and ensure that the size and shape of the stamped parts are more accurate.

[0006] As a preferred embodiment, a vertical rod is respectively installed at each of the four corners of the upper side surface outside the base. One end of the four vertical rods away from the base is connected to each of the four corners of the lower side surface of the cover plate. Four electric push rods are installed on the upper side surface of the cover plate. The telescopic rod of the electric push rod penetrates through the upper side surface of the cover plate, and the telescopic rod of the electric push rod is connected to the upper side surface of the movable plate.

[0007] As a preferred embodiment, a guide post is respectively installed at each of the four corners of the upper side surface of the stamping seat. One end of the guide post away from the stamping seat penetrates through the movable plate and is connected to the lower side surface of the cover plate. The upper die aligned with the central axis of the lower die is installed on the lower side surface of the movable plate.

[0008] As a preferred embodiment, an installation groove in a C-shaped structure is opened at the center position of the upper side surface of the stamping seat. Two chutes are symmetrically opened at the bottom inside the installation groove. Two fixed blocks are symmetrically installed on the left and right sides of the installation groove through cylinders respectively. Two sliders which are matched with the positions and structures of the chutes are integrally formed symmetrically on the lower side surface of the lower die. During use, by means of the special design of the fixing parts and the stamping seat, the replacement of the lower die can be completed in a short time. Compared with the traditional method of using tools to replace the die, the replacement time is greatly reduced, thus improving the production efficiency.

[0009] As a preferred embodiment, a fixing groove matched with the position of the fixed block is formed by recessing downward on the upper side surface of the lower die. The lower side surface of the fixed block abuts against the inside of the fixing groove through the cylinder. Three first magnetic blocks are installed at the center position of the bottom inside the installation groove. Three second magnetic blocks are installed on the lower side surface of the lower die. The first magnetic blocks and the second magnetic blocks are matched in structure and position.

[0010] After adopting the above technical solution, the beneficial effect of the present utility model is that by providing a stamping seat, the stamping seat is installed on the upper side surface of the base through shock absorbers. During use, during the stamping process, the stamping force will generate large vibrations, and the shock absorbers can effectively absorb and reduce these vibrations, keeping the stamping seat relatively stable, which helps to improve the stamping accuracy and ensure that the size and shape of the stamped parts are more accurate.

Compared with the traditional method of using tools to replace the die, the replacement time is greatly reduced, thereby improving the production efficiency. There is no need to use complex tools. The operator only needs to control the cylinder to easily move the fixing block, realizing the installation, disassembly and fixation of the lower die. This not only saves time, but also reduces the operation difficulty and improves the work efficiency. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a stamping device with convenient replacement of the lower die, including: a base 100, a cover plate 130 and a stamping seat 200. The upper surface of the base 100 is provided with a stamping seat 200 through a shock absorber 110, the upper surface of the base 100 is provided with a cover plate 130 through a vertical rod 120, a guiding column 160 is installed between the cover plate 130 and the stamping seat 200, a movable plate 150 is installed on the outer surface of the guiding column 160, an upper die 170 is installed on the lower surface of the movable plate 150, the lower die 270 is fixed on the upper surface of the stamping seat 200 through a fixing member. The fixing member includes: a fixed block 250 and a cylinder 260. The cylinder 260 is installed on the lower surface of the stamping seat 200, and the fixed block 250 is movably installed above the stamping seat 200 through the cylinder 260. An installation groove 220 is opened on the upper surface of the stamping seat 200, a sliding groove 240 is opened at the bottom inside the installation groove 220, and the lower die 270 is clamped and fixed on the upper surface of the stamping seat 200 through the installation groove 220, the fixing member and the sliding groove 240.

[0022] Please refer to Figures 1 to 5 , as the first embodiment of the present invention: a shock absorber 110 is respectively installed at the four corners of the upper surface inside the base 100, and one end of the four shock absorbers 110 away from the base 100 is connected to the four corners of the lower surface of the stamping seat 200. A 5 cm gap is provided between the lower surface of the stamping seat 200 and the base 100 through the shock absorber 110;

[0023] A vertical rod 120 is respectively installed at the four corners of the upper surface outside the base 100, and one end of the four vertical rods 120 away from the base 100 is connected to the four corners of the lower surface of the cover plate 130. Four electric push rods 140 are installed on the upper surface of the cover plate 130. The telescopic rod of the electric push rod 140 penetrates through the upper surface of the cover plate 130, and the telescopic rod of the electric push rod 140 is connected to the upper surface of the movable plate 150;

[0024] A guiding post 160 is respectively installed at each of the four corners of the upper surface of the stamping base 200. One end of the guiding post 160 away from the stamping base 200 penetrates through the movable plate 150 and is connected to the lower surface of the cover plate 130. An upper die 170 aligned with the central axis of the lower die 270 is installed on the lower surface of the movable plate 150;

[0025] When in use, the user first installs the lower die 270 on the upper surface of the stamping base 200. After the installation of the lower die 270 is completed, then the user places the gasket to be stamped inside the lower die 270. When stamping is required, the user first starts the electric push rod 140 on the upper surface of the cover plate 130, so that the electric push rod 140 drives the movable plate 150 to rise or fall along the guiding post 160. When the movable plate 150 descends along the guiding post 160, at this time, the upper die 170 on the lower surface of the movable plate 150 moves towards the upper die 170 on the upper surface of the stamping base 200 (in actual use, the structures of the lower die 270 and the upper die 170 are mutually matched and fitted, so as to complete the stamping operation). After the upper die 170 and the lower die 270 are mutually fitted and the stamping is completed, at this time, the stamping operation of the gasket is completed, and then the movable plate 150 is raised through the above steps and the gasket is taken out from the lower die 270. When the lower die 270 and the upper die 170 are in contact and stamping, the stamping force will generate greater vibration. The shock absorber 110 can effectively absorb and reduce these vibrations, keeping the stamping base 200 relatively stable, which helps to improve the stamping accuracy and ensure that the size and shape of the stamped parts are more accurate.

[0026] Please refer to Figures 1 to 5 As the second embodiment of the present utility model: An installation groove 220 in a U-shaped structure is provided at the central position of the upper surface of the stamping base 200. Two sliding grooves 240 are symmetrically provided at the bottom inside the installation groove 220. Two fixing blocks 250 are symmetrically installed on the left and right sides of the installation groove 220 through cylinders 260 respectively. Two sliding blocks 272 which are matched with the sliding grooves 240 in position and structure are integrally formed symmetrically on the lower surface of the lower die 270;

[0027] A fixing groove 271 which is matched with the position of the fixing block 250 is formed by downward depression on the upper surface of the lower die 270. The lower surface of the fixing block 250 abuts against the inside of the fixing groove 271 through the cylinder 260. Three first magnetic blocks 230 are installed at the central position of the bottom inside the installation groove 220. Three second magnetic blocks are installed on the lower surface of the lower die 270. The first magnetic blocks 230 and the second magnetic blocks are matched in structure and position;

[0028] During use, when the user needs to replace or disassemble the lower mold 270, the user activates the cylinder 260 on the lower surface of the stamping seat 200 at this time, so that the telescopic rod of the cylinder 260 drives the fixing block 250 to rise, thereby making the fixing block 250 away from the upper surface of the stamping seat 200, and then making the lower surface of the fixing block 250 away from the fixing groove 271 of the lower mold 270. At this time, the lower mold 270 loses the restraint of the fixing part, and then the user can take out the lower mold 270 from the installation groove 220 of the stamping seat 200. When installing the lower mold 270, the user first aligns one side of the lower mold 270 with one side of the installation groove 220, and then slides the slider 272 of the lower mold 270 into the inside of the sliding groove 240. Then, the lower surface of the lower mold 270 abuts against the bottom inside the installation groove 220. After the lower mold 270 is slid into the installation groove 220, the first second magnet on the lower surface of the lower mold 270 will be magnetically attracted to the first magnet 230 inside the installation groove 220 and then a first jamming phenomenon occurs. Then, a second jamming phenomenon occurs through the second magnet 230 and the second magnet. Finally, the third magnet 230 is magnetically connected to the second magnet, thereby completing the preliminary fixation of the lower mold 270 (the upper surface of the first magnet 230 is magnetically attracted to the lower surface of the second magnet, and the upper surface of the first magnet 230 is flush with the upper surface of the installation groove 220, and the lower surface of the second magnet is flush with the lower surface of the lower mold 270. Moreover, the first magnet 230 and the second magnet are strong magnets. Therefore, when the first magnet 230 is magnetically connected to the second magnet, the resistance to the sliding of the lower mold 270 is increased, thereby realizing the first jamming phenomenon. When the user continues to push the lower mold 270 at this time, a second jamming occurs further until the third jamming occurs. At this time, the user does not need to push the lower mold 270, and the three second magnets on the lower surface of the lower mold 270 are magnetically attracted to the three first magnets 230 on the upper surface of the installation groove 200), and then the final fixation of the lower mold 270 can be completed by operating the steps of the fixing part in reverse. Thus, the installation of the lower mold 270 is completed. Because during use, by virtue of the special design of the fixing part and the stamping seat 200, the replacement of the lower mold 270 can be completed in a short time. Compared with the traditional method of using tools to replace the mold, the replacement time is greatly reduced, thereby improving the production efficiency. There is no need to use complex tools. The operator only needs to control the cylinder 260 to easily move the fixing block 250, realizing the installation, disassembly and fixation of the lower mold 270. This not only saves time, but also reduces the operation difficulty and improves the work efficiency.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
