Description

Technical Field

[0001] The utility model relates to the field of die clamping machines, in particular to a high-precision hardware stamping die clamping machine. Background Art

[0002] The mold clamping machine is mainly used to test the clamping accuracy of the upper and lower molds. Before the test, the upper and lower molds of the mold are installed on the upper and lower workbenches respectively, and the upper and lower molds are clamped by the upper and lower workbenches to achieve the matching test of the upper and lower molds of the mold.

[0003] Since the lower mold is transferred to the mold closing station via the lower worktable on the machine tool, the lower worktable of the mold closing machines currently on the market is prone to shifting during transfer. At the same time, positioning deviations often occur when the upper worktable is lowered along the lifting guide rail and in the process of turning the mold, resulting in the upper and lower molds being easily misaligned or having mold closing deviations during the mold closing process, resulting in inaccurate upper and lower mold testing, which not only affects the test accuracy of the upper and lower molds, but also affects the test efficiency of the upper and lower mold closing, resulting in poor test accuracy and low test efficiency. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a high-precision metal stamping mold clamping machine, whose overall structural design can not only adjust the verticality and balance of the lifting slide to improve the accuracy of the combination of the lifting slide and the lower workbench, but also limit the left and right sides of the lower workbench through the first limit component and limit the longitudinal movement of the lower workbench through the second limit component, so that the upper mold and the lower mold have the advantages of high mold clamping accuracy, good mold clamping effect and high mold clamping efficiency, thereby ensuring the high test accuracy of the upper and lower mold clamping, which effectively solves the problem that the lower workbench of the current mold clamping machine on the market is prone to shifting during transmission and the upper workbench often has positioning deviations when it is lowered along the lifting guide rail and during the mold turning process, resulting in low mold clamping accuracy of the upper and lower workbenches and low upper and lower mold test accuracy and low upper and lower mold test efficiency. The utility model is achieved through the following technical solutions:

[0005] A high-precision hardware stamping and die-clamping machine comprises a gantry, the lower part of the gantry extending outwardly is provided with a machine tool base, and also comprises a lower workbench arranged on the machine tool base, the left and right sides of the lower workbench are respectively provided with first limit assemblies for limiting the lower workbench, and the rear side of the lower workbench is provided with a second limit assembly; a lifting guide rail assembly is arranged in the gantry, a lifting slide is arranged on the lifting guide rail assembly, an upper workbench is arranged on the lifting slide, and the upper workbench is connected and installed with the lifting slide via a swivel hinge; a first driving member driving the lifting slide to reciprocate and lift along the lifting guide rail assembly is arranged on the top surface of the gantry, a second driving member driving the lower workbench to reciprocate on the machine tool base is arranged on the bottom surface of the lower workbench, and a third driving member driving the upper workbench to rotate around the swivel hinge at a certain angle is arranged in parallel with the first driving member.

[0006] Through the above technical solution, when the third driving member pushes the upper workbench to rotate more than 90 degrees around the hinge, the upper workbench can be installed with the upper mold facing upward, so as to facilitate the upper mold to be placed on the upper workbench and fixedly installed with the upper workbench; after the upper mold is fixedly installed on the upper workbench, the third driving member drives the upper workbench to reset and flip, so that the upper mold of the mold can be suspended on the bottom surface of the upper workbench; and the lower mold of the mold is placed on the lower workbench and fixedly installed with the lower workbench. Among them, it can be fixedly installed by installing clamps on the upper workbench and the lower workbench respectively according to production needs, but it is not limited to this. In another embodiment, the upper and lower molds can also be fixedly installed with the upper and lower workbench respectively by screws. The left and right sides of the lower worktable can be limited and positioned through the first limit component on the machine tool base, and the mold closing station of the lower worktable longitudinally moved into the gantry can be limited and positioned through the second limit component on the machine tool base, so as to improve the positioning accuracy of the lower worktable, so that it can solve the problem that the lower worktable of the mold closing machines currently on the market is prone to shifting during transportation, which causes the upper and lower molds to be easily misaligned during the mold closing process.

[0007] Preferably, positioning adjustment components for positioning the reset and flipping of the upper workbench are respectively arranged on both sides of the lifting slide; the positioning adjustment components include first inclined blocks respectively arranged on the left and right sides of the upper workbench, the upper surface of each first inclined block is an inclined surface, and the first inclined block is provided with a first screw hole; the left and right sides of the lifting slide are also respectively provided with accommodating recesses, the top surface of each accommodating recess is an inclined surface, and each accommodating recess is respectively provided with a second inclined block and a third inclined block, and the second inclined block and the third inclined block are arranged vertically and abutted against each other.

[0008] Preferably, the two surfaces of the second inclined block that are in contact with the third inclined block are both straight surfaces, and the surface of the upper part of the third inclined block is an inclined surface; the inclined surface of the first inclined block and the surface of the second inclined block are offset, fit and contact with each other, and the upper surface of the third inclined block and the upper surface of the accommodating recess are offset, fit and contact with each other.

[0009] Through the above technical solution, when the second inclined block moves downward with the lifting slide and driven by the first driving member, it can collide with the first inclined block. As the first driving member continues to move downward, the second inclined block and the first inclined block after the collision can push the upper worktable to move in the horizontal direction to adjust the position. Since the two second inclined blocks on both sides can collide with the first inclined blocks on the same side when lifting and positioning, it can adjust the position of the upper worktable on both sides of the axis direction of the hinge, so that the reset of the upper mold after flipping the mold can be more accurately combined with the lifting slide.

[0010] Preferably, the lower surface of the second inclined block is an inclined surface, and the second inclined block is provided with an elongated second screw hole, and there is more than one elongated second screw hole; the third inclined block is provided with an elongated third screw hole.

[0011] Preferably, the lifting guide rail assembly includes a first slat and a second slat; the first slat is respectively arranged on the four corners of the gantry, and the second slat is installed on one side of each first slat by installing screws, and the first slat and the second slat adjacent thereto are installed vertically, and the first slat and the second slat are arranged in an L shape after being assembled.

[0012] Preferably, a guide rail is provided on the first slat, and the guide rail is fixedly mounted on the first slat by a first locking screw; a first adjusting screw is arranged adjacent to the first locking screw, and there are more than one first adjusting screws, and the verticality of the surface opposite to the first slat is adjusted by the first adjusting screw; the guide rail is fixedly mounted on the second slat by a second locking screw, and a second adjusting screw is arranged adjacent to the second locking screw, and the verticality of the surface opposite to the second slat is adjusted by the second adjusting screw.

[0013] Preferably, a first support block and a second support block are respectively provided at the four corners of the lifting slide, the first support block is installed on the lifting slide, and the second support block is vertically installed on the first support block; sliders are respectively installed on the two side edges adjacent to the first support block and the second support block, and the sliders slide on the guide rails adjacent thereto.

[0014] Through the above-mentioned technical scheme, four guide rails are vertically arranged on the four corners of the gantry for the sliders on the four corners of the lifting slide to slide, so that by adjusting the verticality and balance of the four guide rails on the gantry, the combination accuracy of the descending lifting slide and the lower workbench can be improved, and finally the accuracy of the upper mold and the lower mold can be improved to ensure that the upper mold and the lower mold can be accurately molded.

[0015] Furthermore, the slider is preferably a copper block. Since the copper block has the advantages of wear resistance and durability, the wear of the slider after long-term use will cause the distance between it and the guide rail to increase, making the lifting slide table prone to swinging during the lowering process. When the copper block is used as the slider, it can avoid reducing the precision of the upper and lower molds due to the wear of the slider.

[0016] Preferably, each first limiting assembly includes a guide wheel seat and a limiting guide wheel; the guide wheel seat is installed on both sides of the machine tool base; the limiting guide wheel is installed in the guide wheel seat; and limiting blocks that can interfere with the limiting guide wheel are respectively provided on the left and right sides of the lower workbench.

[0018] Furthermore, the first driving member and the third driving member are both cylinders. The second driving member is a linear module, preferably a screw linear module, and the specific composition structure and working principle of the linear module are common knowledge and will not be explained in detail here.

[0019] Compared with the existing technology, the beneficial effects of the utility model are as follows: 1. It positions the reset and flipping of the upper worktable by providing a lifting guide rail assembly in the gantry and positioning and adjusting assemblies on both sides of the lifting slide, and provides a second inclined block and a third inclined block in the accommodating recesses on both sides of the lifting slide, respectively. When the two second inclined blocks are lifted and positioned with the lifting slide and driven by the first driving member, they can respectively conflict with the first inclined blocks on the same side therewith, so that the two second inclined blocks move downward and conflict with the first inclined blocks on the same side therewith, which can drive the upper worktable to move in the horizontal direction and adjust the positioning, and can drive the upper worktable to adjust and position on both sides of the axial direction of the rotating hinge, so that the reset of the upper mold after the mold flipping can be more accurately combined with the positioning of the lifting slide, so as to solve the problem that the upper worktable of the current mold clamping machine on the market often has positioning deviation during the mold flipping process.

[0020] 2. The first limit assembly is respectively provided on both sides of the lower workbench and the second limit assembly is provided on the rear side of the lower workbench, so that the lower workbench can be limited and positioned by the first limit assembly and the second limit assembly to improve the positioning accuracy of the lower workbench; and the upper workbench can be positioned and adjusted by the lifting guide rail assembly, and the lower workbench can be positioned and adjusted by the first limit assembly and the second limit assembly to make the mold positioning of the upper mold and the lower mold more accurate.

[0021] 3. The structure of the lifting guide rail assembly is designed so that the verticality and balance of the four guide rails on the gantry can be adjusted to improve the accuracy of the combination of the lifting slide and the lower workbench, so as to solve the problem of positioning deviation that often occurs when the upper workbench of the current mold clamping machine is lowered along the lifting guide rail, and finally improve the precision of the mold clamping of the upper and lower molds. The wear of the slider after long-term use will increase the distance between it and the guide rail, causing the lifting slide to swing during the lowering process. The slider is set as a copper block, which has the advantages of wear resistance and durability. When the copper block is used as the slider, the precision of the mold clamping of the upper and lower molds can be avoided from being reduced due to the wear of the slider.

The second inclined block 17 is provided with an elongated second screw hole 19 , and there is more than one elongated second screw hole 19 ; the third inclined block 18 is provided with an elongated third screw hole 20 .

[0037] In one of the embodiments, the lifting guide rail assembly 6 includes a first slat 61 and a second slat 62; the first slat 61 is respectively arranged on the four corners of the gantry 1, and the second slat 62 is installed on a side of the first slat 61 by installing screws 63, and the first slat 61 and the second slat 62 are arranged perpendicular to each other; a guide rail 64 is provided on the first slat 61, and the guide rail 64 can adjust the verticality of the surface opposite to the first slat 61 through a first adjusting screw 65, and the guide rail 64 is fixedly installed on the first slat 61 through a first locking screw 66; the guide rail 64 can adjust the verticality of the surface opposite to the second slat 62 through a second adjusting screw 67, and the guide rail 64 is fixedly installed on the second slat 62 through a second locking screw 68.

[0038] In one of the embodiments, a first support block 69 and a second support block 690 are respectively provided at the four corners of the lifting slide 7, the first support block 69 is installed on the lifting slide 7, and the second support block 690 is vertically installed on the first support block 69; the two side edges adjacent to the first support block 69 and the second support block 690 are respectively installed with sliders 692, and the slider 692 slides on the guide rail 64 adjacent thereto.

[0039] In one embodiment, each first limiting assembly 4 includes a guide wheel seat 41 and a limiting guide wheel 42; the guide wheel seat 41 is installed on both sides of the machine tool base 2; the limiting guide wheel 42 is installed in the guide wheel seat 41; and limiting blocks 43 that can interfere with the limiting guide wheel 42 are respectively provided on the left and right sides of the lower workbench 3.

[0040] In one embodiment, more than one second limiting assembly 5 is provided, and each second limiting assembly 5 includes a protrusion 51 and a concave seat 52 that can be limitedly docked with the protrusion 51; the protrusion 51 is installed on the rear side of the lower workbench 3, and the concave seat 52 is installed on the rear side of the machine tool base 2.

[0041] In one of the embodiments, the structural design principle and working process of the high-precision metal stamping mold clamping machine are as follows: since the upper workbench 8 can be raised and lowered along with the lifting slide 7, when the first driving member 10 drives the lifting slide 7 to descend to an appropriate height along the lifting guide rail assembly 6 according to production needs, the upper mold of the mold can be conveniently installed on the flipped upper workbench 8.

[0042] Furthermore, since the third driving member 12 can drive the upper worktable 8 connected thereto to rotate back and forth around the hinge 9 when performing telescopic movement, when the third driving member 12 drives the upper worktable 8 to rotate clockwise around the hinge 9 greater than 90 degrees, the surface of the upper mold installed on the upper worktable 8 can face upward, so as to facilitate placing the upper mold on the upper worktable 8 and fixing the upper mold and the upper worktable 8.

[0043] After the upper die is fixedly installed on the upper workbench 8, the third driving member 12 drives the upper workbench 8 to reset and flip, so that the upper workbench 8 is restored to a horizontal and stationary state in the gantry 1. At this time, the upper die of the mold is suspended on the bottom surface of the upper workbench 8; during the reset and flipping process of the upper workbench 8, the positioning and adjustment components 13 on both sides of the lifting slide 7 can position the reset and flipping of the upper workbench 8; it is achieved by providing accommodating recesses 16 on both sides of the lifting slide 7, the top surface of each accommodating recess 16 is an inclined surface, and each accommodating recess 16 is provided with a second inclined block 17 and a third inclined block 18, and the second inclined block 17 and the third inclined block 18 are arranged in a vertically conflicting manner. It is also achieved by setting the two conflicting surfaces of the second inclined block 17 and the third inclined block 18 as straight surfaces, the upper surface of the third inclined block 18 is an inclined surface, and the upper surface of the third inclined block 18 and the upper surface of the accommodating recess 16 are mutually offset, fitted and conflicted. The lower surface of the second inclined block 17 is an inclined surface, and the second inclined block 17 is provided with one or more elongated second screw holes 19; the second inclined block 17 can be locked in the accommodating recess 16 by installing screws in the corresponding second screw holes 19; similarly, the third inclined block 18 is provided with an elongated third screw hole 20, so that the third inclined block 18 can be locked on the upper surface of the accommodating recess 16 by installing screws in the third screw holes 20.

[0044] As the third inclined block 18 is locked, the inclined surface of the accommodating recess 16 will conflict with the inclined surface of the third inclined block 18, so that the third inclined block 18 can push the second inclined block 17 to move downward; by respectively providing the first inclined block 14 on both sides of the upper workbench 8 and setting the upper surface of the first inclined block 14 as an inclined surface, the inclined surface of the first inclined block 14 can be offset, fit and conflict with the inclined surface of the second inclined block 17.

[0045] Since the two second inclined blocks 17 on both sides can respectively collide with the first inclined blocks 14 on the same side when the lifting slide 7 is lifted and positioned, the two second inclined blocks 17 on both sides can drive the upper workbench 8 to move and adjust its position in the horizontal direction when they move downward and collide with the first inclined blocks 14 on the same side. This can drive the upper workbench 8 to adjust and position on both sides of the axial direction of the rotating hinge 9, so that the reset of the upper mold after mold turning can be more accurately combined with the lifting slide 7 to avoid the phenomenon of positioning deviation of the upper workbench 8 during the mold turning process.

[0046] Next, the lower mold of the mold is placed on the lower workbench 3 and the lower mold is fixedly installed with the lower workbench 3. Since the lower workbench 3 can be longitudinally transported back and forth on the machine tool base 2 under the drive of the second driving member 11, when the lower mold of the mold is transported into the mold test station in the gantry 1 along with the lower workbench 3 and driven by the second driving member 11, the protrusion 51 in the second limiting component 5 can be limitedly docked and engaged with the concave seat 52, so that the longitudinal movement of the lower workbench 3 can be limited and positioned through the second limiting component 5, which ensures that the lower mold can be accurately positioned in the mold test station in the gantry 1 as the lower workbench 3 is transported.

[0047] When the first driving member 10 drives the lifting slide 7 to descend along the lifting guide rail assembly 6, it can drive the upper workbench 8 and the upper mold suspended below the upper workbench 8 to descend to the lower mold, so that the upper mold and the lower mold can be accurately molded.

[0048] The first limiting assembly 4 is provided on both sides of the lower workbench 3, and the first limiting assembly 4 includes a guide wheel seat 41 and a limiting guide wheel 42; when the lower workbench 3 is transferred to the mold closing station in the gantry 1, the limiting guide wheels 42 in the first limiting assembly 4 on the left and right sides of the lower workbench 3 can respectively collide with the limiting blocks 43 on the left and right sides of the lower workbench 3, so that the left and right sides of the lower workbench 3 can be limited to avoid the lower workbench 3 from being easily displaced during the transfer process and affecting the mold closing accuracy. The first limiting assembly 4 and the second limiting assembly 5 are used to limit and position the workbench respectively, so that the positioning accuracy of the lower workbench 3 can be greatly improved; and the upper mold and the lower mold are more accurately positioned by positioning and adjusting the upper workbench 8 and the lower workbench 3.

[0049] It also has a first slat 61 and a second slat 62 respectively arranged in the lifting guide rail assembly 6, the first slat 61 is installed on one side of the first slat 61 by means of an installation screw 63, and the first slat 61 and the second slat 62 are arranged perpendicular to each other, a guide rail 64 is provided on the first slat 61, the guide rail 64 is fixedly installed on the first slat 61 by means of a first locking screw 66, and the guide rail 64 can adjust the verticality of the surface opposite to the first slat 61 by means of a first adjusting screw 65; the guide rail 64 is fixedly installed on the second slat 62 by means of a second locking screw 68, and the guide rail 64 can adjust the verticality of the surface opposite to the second slat 62 by means of a second adjusting screw 67. At the same time, the first support blocks 69 and the second support blocks 690 are respectively provided on the four corners of the lifting slide 7, and the two sides adjacent to each first support block 69 and each second support block 690 are respectively installed with sliders 692, and the sliders 692 can slide on the guide rails 64 adjacent thereto, so that the verticality and balance of the four guide rails 64 on the gantry 1 can be adjusted to improve the accuracy of the combination of the lifting slide 7 with the lower workbench 3 when it slides down, and finally the upper mold and the lower mold can be accurately molded.

[0050] Its overall structural design can not only adjust the verticality and balance of the lifting slide 7 to improve the accuracy of the combination of the lifting slide 7 and the lower workbench 3, but also limit the left and right sides of the lower workbench 3 through the first limit component 4 and the longitudinal movement of the lower workbench 3 through the second limit component 5, so that the upper mold and the lower mold have the advantages of high mold clamping accuracy, good mold clamping effect and high mold clamping efficiency, thereby ensuring the high test accuracy of the upper and lower mold clamping. It effectively solves the problems of the lower workbench of the current clamping machine on the market being prone to displacement during transportation and the upper workbench often having positioning deviations when descending along the lifting guide rail and in the process of turning the mold, resulting in low mold clamping accuracy of the upper and lower workbenches and low upper and lower mold testing accuracy and low upper and lower mold testing efficiency.
