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] In the face of the thriving development of the new energy vehicle industry, in order to improve the quality of metal stamping parts and reduce the cost of manual assembly, automobile OEMs gradually compress the parts of the whole vehicle to meet the increasingly stringent requirements of the OEMs, which leads to the increasing size of the single stamping product, which makes the metal stamping mold more and more precise and larger. After the metal mold is developed, it is necessary to test the mold in the punch press immediately to check the quality of the mold. The whole process requires dozens of times. The traditional vertical mold clamping machine is generally driven by the lifting cylinder to open and close the mold. The vertical mold clamping machine of this structure cannot ensure that its two ends can be lifted and lowered synchronously; and the upper workbench of the traditional vertical mold clamping machine cannot be turned over and the upper workbench cannot be positioned after the flip. Since the metal mold occupies a large space, it is difficult to place it in the original punch press space. The vertical mold clamping machine with a traditional structure affects the overall workshop planning due to the excessive height of the bed, and the long mold opening time affects the work efficiency. Therefore, the traditional vertical mold clamping machine cannot meet the current high-precision requirements of the metal mold clamping, so the demand for high-precision metal mold clamping machines is increasing.

[0003] The length and width of the upper mold of the existing punch press are as high as 6M*2.5M respectively, and the weight of the upper mold is as high as 25 tons. When the mold of the punch press fails, it is difficult to quickly transfer the large and heavy upper and lower molds to the mold clamping machine for mold repair. 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 makes the occupied space and the machine body height only two-thirds of the traditional vertical mold clamping machine, and its mold opening and closing time is only one-half of the traditional vertical mold clamping machine, which not only greatly improves the efficiency of mold opening and closing, but also makes the machine tool cost lower than the traditional vertical mold clamping machine, so that it has the advantages of low production cost, high stamping accuracy, high processing efficiency and strong versatility, which effectively solves the problem of low work efficiency of traditional vertical mold clamping machines due to the high bed body affecting the overall workshop planning and the long mold opening time. The utility model is achieved through the following technical solutions:

[0005] The high-precision metal stamping and clamping machine comprises a base and a top cover. The four corners of the base are provided with columns.

[0009] Through the above technical solution, when the mold clamping machine is closing the mold, the electric cylinders on both sides drive the slides to slide downward respectively, and the linkage between the various lifting balance synchronization components enables the slides on the two inner sides of the two oppositely arranged groups of columns to descend synchronously. When the upper worktable slides down in a balanced manner with the slide and closes with the lower worktable, the upper mold and the lower mold can be accurately closed, which can improve the accuracy and efficiency of mold trial.

The specific composition structure and working principle of the worm gear assembly are common knowledge and will not be explained in detail here.

[0013] Through the above technical solution, since the brake motor is connected to the worm gear assembly through the reducer, when the brake motor drives the worm gear assembly to rotate through the reducer, it can drive the flip wallboard to rotate. When the first flip limit block blocks the flip movable limit block, it can position the flip wallboard for upward rotation, so that the upper mold on the upper workbench can be positioned upward. When the locking cylinder drives the latch to insert into one of the positioning holes, it can lock the flip wallboard that has completed the upward rotation and positioning to prevent the upper mold from continuing to flip. When the second flip limit block blocks the flip movable limit block, it can position the flip wallboard for downward rotation, so that the upper mold on the upper workbench can be positioned downward. At this time, when the locking cylinder drives the latch to insert into another positioning hole, it can lock the flip wallboard that has completed the downward rotation and positioning to prevent the upper mold from continuing to flip. It can ensure that when the mold clamping machine is clamping or opening the mold, the upper workbench remains fixed and does not flip during the lifting and sliding process, so that the upper mold and the lower mold can be accurately clamped, thereby greatly improving the efficiency of its mold trial.

[0028] 3. A shift assembly is arranged under the lower workbench. When the lifting cylinder in the shift assembly raises the lifting block, the lifting block can be at the same level as the removal guide rail. The lower workbench can move on the removal guide rail through rollers. When the lower workbench moves out of the base through rollers, it can vacate space for the upper workbench. In addition, it is convenient to place hardware molds on the lower workbench or to replace lower molds of other specifications, so as to solve the problem that the traditional vertical mold clamping machine is difficult to place hardware molds with large space due to the limited space between the upper and lower workbenches; when the lower workbench moves into the base through rollers, In preparation for the lowering of the upper mold and the closing of the lower mold, when the lifting cylinder lowers the lifting block, the roller can be lowered accordingly, so that the lower workbench can be placed on the base, which can reduce the weight extrusion of the roller on the base to avoid the roller being crushed or deformed by the extrusion between the lower workbench and the base. At the same time, the lower workbench can receive the upper mold and lower mold that need to be repaired transmitted by the punch press at any time, so that the upper mold and lower mold that need to be repaired can be quickly unloaded from the punch press, and the upper mold and lower mold can be placed on the lower workbench, avoiding the punch press being placed with the upper mold and lower mold that need to be repaired for a long time and affecting the work of the punch press.

[0029] 4. The structure of the flipping mechanism is designed so that the upper workbench can be flipped through the flipping mechanism. When the first flipping limit block blocks the flipping movable limit block, the flipping wall panel can be positioned for upward rotation, so that the upper mold on the upper workbench is positioned upward, and the two locking cylinders respectively drive the pins to insert into relative positioning holes to lock the flipping wall panel to prevent the upper mold from continuing to flip; when the second flipping limit block blocks the flipping movable limit block, the flipping wall panel can be positioned for downward rotation, so that the upper mold on the upper workbench is positioned downward, and the two locking cylinders respectively drive the pins to insert into relative positioning holes to lock the flipping wall panel to prevent the upper mold from continuing to flip, which ensures high clamping accuracy between the upper and lower molds, thereby greatly improving the efficiency of mold trial, and its opening and closing time is only half of that of the traditional vertical clamping machine.

[0030] 5. The electric cylinder in the high-precision metal stamping and die-clamping machine of the utility model drives the upper worktable to move up and down with an accuracy of 0.02mm. The brake motor can drive the upper worktable to flip through the worm gear assembly. The upper mold mounted on the upper worktable can weigh up to 25 tons, and the maximum size of the upper mold can reach 6M*2.5M. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In one of the embodiments, when two locking cylinders 84 are provided on the side of the slide 7, the two locking cylinders 84 are symmetrically arranged on both sides of the worm gear assembly 80, and the two positioning holes 86 are symmetrically arranged on both sides of the worm gear assembly 80, one of the locking cylinders 84 is arranged corresponding to one of the positioning holes 86, and the other locking cylinder 84 is arranged corresponding to the other positioning hole 86.

[0052] In one of the embodiments, the structural design principle of the high-precision metal stamping and mold clamping machine is as follows: a first vertical sliding guide adjustment component 61 and a second vertical sliding guide adjustment component 62 are respectively provided on two adjacent side surfaces of each column 3, so that the slide 7 can be lifted and slid between the two columns 3 on the same end of the base 1 through the first vertical sliding guide adjustment component 61 and the second vertical sliding guide adjustment component 62. The coordinated use of the first vertical sliding guide adjustment component 61 and the second vertical sliding guide adjustment component 62 can guide the lifting and sliding of the slide 7.

The upper workbench 9 can perform mold opening and closing movements with the up and down sliding of the slide 7, and the second vertical sliding guide adjustment component 62 can prevent the upper workbench 9 from tilting when it is lifted and slid.

[0053] When the mold clamping machine needs to close the mold, the electric cylinders 10 on both sides drive the slide 7 to slide downward respectively, and the linkage between the lifting balance synchronization components 11 enables the slides 7 on the two inner sides of the two oppositely arranged groups of columns 3 to descend synchronously. When the upper workbench 9 slides down in a balanced manner with the slide 7 and closes with the lower workbench 5, the upper mold and the lower mold can be accurately closed, which improves the accuracy and efficiency of the mold trial.

[0054] When the lifting cylinder 42 raises the lifting block 43, the lifting block 43 and the removal guide rail 44 can be at the same horizontal height, and the lower workbench 5 can be moved on the removal guide rail 44 through the roller 45. When the lower workbench 5 is moved out of the base 1 through the roller 45, it can make room for the upper workbench 9. At the same time, it is also convenient to replace the lower molds of different specifications on the lower workbench 5 or to place the hardware molds of the same size, so as to solve the problem that it is difficult to place the hardware molds in the traditional punch press, and it meets the demand for testing the hardware molds of different specifications; when the lower workbench 5 is moved into the base 1 through the roller 45, it can prepare for the descent of the upper mold and the closing of the lower mold. When the lifting cylinder 42 in the shifting assembly 4 is lowered, the lifting block 43 can be driven to lower, so that the roller 45 can be lowered along with the lowering of the lifting block 43, and the lower workbench 5 can be placed on the base 1 along with the lowering of the roller 45 to reduce the support of the roller 45 on the weight of the base 1, thereby preventing the roller 45 from being squeezed by the base 1 and being crushed.

[0055] When the brake motor 82 in the flipping mechanism 8 drives the worm gear assembly 80 to rotate forward and backward through the reducer 83, it can drive the flipping wall panel 81 to rotate forward and backward accordingly. When the flipping wall panel 81 rotates upward under the drive of the brake motor 82, the first flipping limit block 87 blocks the flipping movable limit block 89 to position the flipping wall panel 81 for upward rotation, so that the upper mold on the upper workbench 9 can be positioned upward; when the locking cylinder 84 drives the pin 85 to insert into one of the positioning holes 86, the flipping wall panel 81 that has completed the upward rotation can be locked to prevent the upper mold from continuing to flip, thereby positioning the upper mold facing upward, which not only facilitates the staff to replace upper molds of different specifications according to production needs to solve the problem that it is difficult to place hardware molds in the traditional punching machine space, making it suitable for processing hardware molds of different sizes, but also the upper mold facing upward after rotation can increase the space between the upper workbench 9 and the lower workbench 5. When the second flip limit block 88 blocks the flip movable limit block 89, it can position the flip wall panel 81 for downward reset rotation, so that the upper mold on the upper workbench 9 can be positioned downward; when the locking oil cylinder 84 drives the latch 85 to insert into another positioning hole 86, the flip wall panel 81 that has completed the downward rotation and positioning can be locked to prevent the upper mold from continuing to flip, which can ensure that when the mold clamping machine is clamping or opening the mold, the upper workbench 9 remains fixed and does not flip during the lifting and sliding process, so that the upper mold and the lower mold can be accurately clamped, thereby greatly improving the efficiency of its mold trial. When the mold clamping machine stops working in a power outage, the brake motor 82 can lock the position when it stops working, and the brake motor 82 rotates without being affected by external forces, and the upper workbench 9 is locked by the worm gear assembly 80 to prevent the upper workbench 9 from freely flipping under its own gravity after the power outage, so as to improve the safety of the mold clamping machine.

[0056] The first vertical sliding guide adjustment component 61 can adjust the verticality of the slider adjustment pad 612 through the first adjustment screw 610, and the first guide rail adjustment pad 614 can adjust the gap between it and the first vertical guide rail 615 through the second adjustment screw 616 to adjust the verticality of the first vertical guide rail 615, so that the slider adjustment pad 612 can be balanced with the first vertical guide rail 615, so as to achieve the vertical guidance of the lifting and sliding of the slide 7, which enables the slide 7 to lift and slide smoothly without swinging. The second guide rail adjustment pad 623 in the second vertical sliding guide adjustment component 62 can adjust the gap between it and the second vertical guide rail 624 through the third adjustment screw 625, so as to adjust the contact limit between the second vertical guide rail 624 and the second self-lubricating slider 622, so as to achieve the vertical guidance of the lifting and sliding of the slide 7, which not only ensures that the slide 7 can lift and slide smoothly without swinging, but also prevents the upper workbench 9 from tilting due to the different heights of the two ends during the lifting process.

[0057] When two locking cylinders 84 are provided on the side of the slide 7, when the brake motor 82 drives the worm gear assembly 80 to rotate, it can drive the flip wall panel 81 to rotate. When the first flip limit block 87 blocks the flip movable limit block 89, it can position the upward rotation of the flip wall panel 81, so that the upper mold on the upper workbench 9 is positioned upward. When the two locking cylinders 84 respectively drive the pins 85 to insert into the relative positioning holes 86, the flip wall panel 81 that has completed the upward flipping can be locked to prevent the upper mold from continuing to flip. When the second flip limit block 88 blocks the flip movable limit block 89, it can position the downward rotation of the flip wall panel 81, so that the upper mold on the upper workbench 9 is positioned downward, and the two locking cylinders 84 respectively drive the pins 85 to insert into the relative positioning holes 86 to lock the flip wall panel 81 that is flipped downward to prevent the upper mold from continuing to flip. This ensures that when the mold clamping machine is closing or opening the mold, the upper workbench 9 remains fixed and does not flip during the process of lifting and sliding, so that the upper mold and the lower mold can be accurately closed, thereby greatly improving the efficiency of its mold trial.

[0058] The mold clamping machine adopts a two-side synchronization method to ensure the mold clamping accuracy. The overall structural design ensures that the two ends of the upper workbench 9 can be raised and lowered synchronously. The upper mold can not only be turned over with the upper workbench 9 through the turning mechanism 8, but the turning mechanism 8 can also position the turned upper workbench 9 to prevent the upper workbench 9 from continuing to turn over, thereby ensuring the high mold clamping accuracy of the upper and lower molds. The overall floor space and body height are only two-thirds of those of the traditional vertical mold clamping machine, and the mold opening and closing time is only half of that of the traditional vertical mold clamping machine, which not only greatly improves the efficiency of mold opening and closing, but also achieves its strong versatility. It also makes the machine tool cost lower than that of the traditional vertical mold clamping machine, so that it has the advantages of low production cost, high stamping accuracy and high processing efficiency. It timely solves various problems of automobile mold supporting manufacturers, and effectively solves the problem of low work efficiency of traditional vertical mold clamping machines due to the high bed, which affects the overall workshop planning and the long mold opening time.
