Description

Technical Field

[0001] The utility model relates to the technical field of stamping, and more specifically to a stamping device for rapid prototyping of hardware accessories. Background Art

[0002] In the process of hardware manufacturing, stamping is generally used to manufacture hardware; the processes of existing stamping devices are loading and fixing, stamping, and demolding and unloading. Since the hardware can only be stamped one by one and the template cannot be replaced, the mold stamping is single and the efficiency of the stamping device is low.

[0003] In view of the above problems, regarding the technical problem that the template cannot be replaced, after a lot of searches, a precision hardware stamping and forming device with patent number CN212682150U was found, which belongs to the field of mold stamping. A precision hardware stamping and forming device includes a base, a stamping table is fixedly connected to the upper end of the base, a fixed frame is fixedly connected to the upper end of the stamping table, a pair of hydraulic rods are fixedly connected to the top wall of the fixed frame, a stamping plate is fixedly connected between the pair of hydraulic rods, the stamping plate is located at the lower end of the hydraulic rod, the lower end of the stamping plate is fixedly connected to the upper template, a pair of through holes are chiseled at the upper end of the stamping plate, a pair of through holes are located on both sides of the hydraulic rod, and sliding rods are slidably connected inside the through holes, a pair of stamping tables are chiseled at the upper end, a lower template is provided inside the stamping groove, a pair of mounting grooves are chiseled on the bottom wall of the stamping groove, and a pair of sliding grooves are chiseled on the inner wall of the pair of mounting grooves, which can realize the replacement of the template, make the mold stamping diverse, and effectively improve the efficiency of the stamping and forming device; However, the technical solution provided by the patent has the following problems:

[0004] (1) When replacing the mold, the user needs to first press a pair of limit rods inward, and then the ejector block pushes the lower mold upward through the spring telescopic rod. This operation does not affect the replacement speed of the upper mold, because the upper mold still needs to be assembled with bolts. Therefore, this method cannot solve the problem of speed when replacing a pair of molds at the same time;

[0005] (2) After the template is replaced, since the new template may have a thickness difference, if the original stamping structure is still used, it may cause over-pressing when the template is pressed, which will cause damage to the mold and workpiece.

[0006] The utility model can quickly disassemble and replace a pair of templates through the template disassembly and assembly mechanism, and can timely adjust the limiting distance through the template limiting mechanism so as to use the replaced template. Utility Model Content

[0018] 1. By setting up the iron template disassembly and assembly mechanism, when the iron template needs to be disassembled and assembled, the user can rotate the two threaded sleeves respectively to allow the two threaded columns to move along the threads of the threaded sleeves, thereby driving the magnetic plate away from the upper iron template and the lower iron template, so that the magnetic attraction between the magnetic plate and the upper iron template and the lower iron template is reduced; then the user can easily remove the upper iron template and the lower iron template respectively; and when the upper iron template and the lower iron template need to be installed, it is only necessary to reinstall the replaced upper iron template and the lower iron template in the original position, and then rotate the threaded sleeve in the opposite direction to make the magnetic plate close to the upper iron template and the lower iron template, so that it can be fixed by magnetic adsorption again, making the disassembly and assembly process of the upper iron template and the lower iron template more convenient;

[0019] 2. By setting up the iron template limiting mechanism, when replacing iron templates of different thickness specifications, the user can rotate the top of the threaded rod to allow the adjustment block to rotate along the thread of the threaded rod.

[0028] In the embodiment of the utility model, the iron formwork disassembly and assembly mechanism includes: threaded columns 8 respectively penetrate the bottom end of the stamping plate 4 and the top middle of the base 1, the four sides of the threaded column 8 are rotatably connected with the stamping plate 4 and the base 1, and one end of the threaded column 8 is rotatably connected with the magnetic plate 9. Therefore, the threaded column 8 plays a supporting and connecting role, and at the same time, through the connection with the magnetic plate 9, the movement function of the magnetic plate 9 is realized; the magnetic plate 9 is installed at one end of the threaded column 8, and the relative position can be adjusted by the rotation connection with the threaded column 8. When disassembling the iron formwork, the user rotates the threaded sleeve 10 to let the threaded column 8 move along the threaded sleeve. The threaded sleeve 10 moves threadably, driving the magnetic plate 9 away from the upper iron template 6 and the lower iron template 7, reducing the magnetic attraction force, thereby making it easier to remove the iron template; one end of the threaded sleeve 10 is rotatably connected to the top end of the stamping plate 4 and the bottom end of the base 1 respectively, and at the same time, the inner wall of the threaded sleeve 10 is threadedly connected to the threaded column 8 around. The user can control the movement of the threaded column 8 by rotating the threaded sleeve 10, thereby adjusting the distance between the magnetic plate 9 and the upper and lower iron templates. When the iron template needs to be installed, the threaded sleeve 10 can be rotated in the opposite direction to make the magnetic plate 9 close to the upper and lower iron templates, thereby re-realizing the magnetic adsorption and fixing effect.

[0029] In the embodiment of the utility model, the four sides of the threaded column 8 are rotatably connected to the stamping plate 4 and the base 1, and one end of the threaded column 8 is rotatably connected to the magnetic plate 9, so that the threaded column 8 can drive the magnetic plate 9 to move and upgrade during the upgrade and adjustment process without driving the magnetic plate 9 to rotate.

[0030] In the embodiment of the utility model, one end of the threaded sleeve 10 is rotatably connected to the top end of the stamping plate 4 and the bottom end of the base 1 respectively, and the inner wall of the threaded sleeve 10 is threadedly connected to the four sides of the threaded column 8, so that the threaded column 8 can be driven to rise and fall when the threaded sleeve 10 rotates in situ.

[0031] In the embodiment of the utility model, the iron template limiting mechanism includes: the threaded rod 11 is respectively arranged at the left and right ends of the inside of the punching table 2, and the top end thereof penetrates to the top end of the punching table 2 and is rotatably connected to the inner wall; the function of the threaded rod 11 is to calibrate the height of the adjustment block 12 to adapt to iron templates of different thickness specifications; the adjustment block 12 is located at the lower end of the outer surface of the threaded rod 11 and is connected to the threaded rod 11 through a thread; the fixed block 13 is fixed to the outside of the adjustment block 12 and extends to the inside of the guide groove 14 and is slidably connected to it; the function of the adjustment block 12 is to move in the vertical direction with the rotation of the threaded rod 11, so as to adjust the height; the function of the fixed block 13 is to limit the adjustment block 12 to move only in the vertical direction The guide groove 14 is located at the left and right ends of the inner wall of the punching table 2, and the extended part of the fixed block 13 is slidably connected with the guide groove 14; the function of the guide groove 14 is to ensure that the fixed block 13 can only move within a predetermined range, that is, along the vertical direction, to limit the moving range of the adjustment block 12, thereby controlling the height adjustment range of the iron template; the threaded rod 11 and the guide rod 5 are arranged parallel to each other, and may not have a direct functional connection, but the guide rod 5 plays a role in supporting the iron template to keep it stable; through the movement of the adjustment block 12, the user can adjust the height to ensure that the subsequent iron template pressing will not be excessive, thereby ensuring the safety and stability of the mold use.

[0032] In the embodiment of the utility model, the inner wall of the adjusting block 12 is threadedly connected to the outer surface of the threaded rod 11, and the fixed block 13 extends to the inside of the guide groove 14 at one end away from the adjusting block 12 and is slidably connected to the guide groove 14, so that when the threaded rod 11 is rotated, the fixed block 13 is restricted to slide up and down in the guide groove 14, so that the adjusting block 12 can only move up and down along the outer surface of the threaded rod 11, so as to ensure that the adjusting block 12 is smoothly upgraded and adjusted.

[0033] In the embodiment of the utility model, the threaded rod 11 and the guide rod 5 are arranged parallel to each other, and the adjusting block 12 is located directly below the stamping plate 4, so that the adjusting block 12 is always directly below the stamping plate 4 when it is raised or lowered, and the adjusting block 12 after upgrading and adjusting can limit the stamping plate 4 to prevent the stamping plate 4 from being over-pressed and causing damage to the iron template.

[0034] Working principle: First, when the iron template needs to be disassembled, the user can rotate the two threaded sleeves 10 respectively to allow the two threaded columns 8 to move along the threads of the threaded sleeves 10, thereby driving the magnetic plate 9 away from the upper iron template 6 and the lower iron template 7, so that the magnetic attraction between the magnetic plate 9 and the upper iron template 6 and the lower iron template 7 is reduced; then the user can easily remove the upper iron template 6 and the lower iron template 7 respectively; and when the upper iron template 6 and the lower iron template 7 need to be installed, it is only necessary to install the replaced upper iron template 6 and the lower iron template 7 in the original position again, and then rotate the threaded sleeve 10 in the opposite direction. By bringing the magnetic plate 9 close to the upper iron template 6 and the lower iron template 7, they can be fixed again by magnetic adsorption; after replacing the iron templates with different thickness specifications, the user can rotate the top of the threaded rod 11 to allow the adjusting block 12 to rotate along the threaded rod 11. Since the fixing block 13 connected to the adjusting block 12 is slidably connected to the guide groove 14, the adjusting block 12 can only move in the vertical direction. After that, the user only needs to adjust the height of the adjusting block 12 to the same as the thickness difference of the iron template before and after replacement, so that the subsequent iron template pressing will not be excessive, thereby making the iron template safer to use after replacement.
