Description

Technical Field

[0001] The utility model relates to a high-precision punching machine die for a titanium metal cup cover. Background Art

[0002] Titanium cup lids are generally formed by stamping. The stamping equipment generally includes a punch and a lower die set on a stamping machine. The lower die is connected to the workbench of the stamping machine by sliding back and forth. When stamping, the pre-cut titanium metal is placed on the lower die, and the lower die moves forward to under the punch. The punch performs a stamping, and then the lower die is pulled out to demold the titanium cup lid on the lower die.

[0003] It is obvious that the accuracy of the lower die displacement directly affects the forming accuracy of the titanium metal cup cover; and in the prior art, the lower die generally only relies on the limit block located at the front end for positioning. With long-term use, the continuous wear of the connection between the lower die and the limit block will obviously lead to a continuous decrease in the positioning accuracy of the lower die, thereby reducing the forming accuracy of the titanium metal cup cover.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, a high-precision stamping machine mold for a titanium cup cover comprises a punch and a lower die 1 arranged on the stamping machine, wherein the lower die 1 is slidably connected to a workbench 2 of the stamping machine;

[0024] A limit block 3 corresponding to the lower mold 1 is fixed at the front end of the workbench 2, and a ramp 4 protruding toward the lower mold 1 is provided at the bottom of the rear end of the limit block 3. A magnet 5 is fixed on the limit block 3 above the ramp 4, and an elastic layer 6 is also provided on the limit block 3 above the magnet 5.

[0025] The bottom of the front end of the lower die 1 has a limit groove corresponding to the limit block 3, and the rear end of the lower die 1 is also connected to a driving mechanism 7 through a connecting rod 8. A telescopic sleeve 9 is also provided at the connection between the connecting rod 8 and the lower die 1;

[0026] It also includes a positioning mechanism, which includes a plurality of positioning columns 10 connected to the workbench 2 by lifting, the top of each positioning column 10 is in a frustum shape, and the bottom of the lower mold 1 is provided with a positioning hole corresponding to the positioning column 10.

[0027] Preferably, there are four groups of positioning posts 10 and positioning holes.

[0028] The working principle of the above structure is: when stamping the titanium metal cup cover, the cut titanium metal sheets are first placed on the lower die 1 in sequence; after placement, the driving mechanism 7 drives the lower die 1 to move forward to abut against the limit block 3, and the lower die 1 first abuts against the elastic layer 6 and is then adsorbed by the magnet 5. At this time, the telescopic sleeve 9 and the elastic layer 6 cooperate to buffer the impact force when the lower die 1 abuts against the limit block 3, so that the lower die 1 and the limit block 3 are smoothly combined, and the wear rate of this position is delayed; after the front end of the lower die 1 is adsorbed by the magnet 5, each positioning column 10 is slowly raised and inserted into the corresponding positioning column 10, and the position of the lower die 1 is further fine-tuned to make the position of the lower die 1 accurately aligned with the punch to ensure the accuracy during stamping.

[0029] The beneficial effects of the above structure are: simple structure, accurate positioning of the lower die 1 through limiting and positioning, so as to ensure the accuracy of the punch when punching; and the lower die 1 and the limit block 3 are not prone to rigid collision, so as to delay the wear speed of the abutment between the lower die 1 and the limit block 3, so that it can maintain a higher positioning accuracy for a longer time.

[0030] Specifically, the driving mechanism 7 is a first cylinder.

[0031] In another embodiment, if Figure 1 As shown, the telescopic sleeve 9 includes a connecting sleeve fixed at the rear end of the lower mold 1, a spring is arranged in the connecting sleeve, and the front end of the connecting rod 8 is inserted into the connecting sleeve and abuts against the spring.

[0032] In another embodiment, the connecting rod 8 and the connecting sleeve are further provided with corresponding limiting plates and limiting rings, so that the driving mechanism can smoothly pull the lower mold 1 backward.

[0033] In another embodiment, if Figure 1 As shown, the workbench 2 is provided with mounting holes 11 corresponding to the positioning columns 10 , and each positioning column 10 is lifted and connected in the corresponding mounting hole 11 .

[0034] In another embodiment, if Figure 1 As shown, a connecting rod 12 is further provided at the bottom of each positioning column 10 , and the bottom of each connecting rod 12 passes through the workbench 2 and is connected to a fixing frame 13 , and the bottom of the fixing frame 13 is connected to a second cylinder 14 .

[0035] In another embodiment, if Figure 1 As shown, a mounting groove 15 corresponding to the fixing frame 13 and the second cylinder 14 is also provided at the bottom of the workbench 2 .

[0036] In another embodiment, in combination Figure 1 and Figure 3 As shown, the magnet 5 is embedded in the limiting block 3 , and the outer end surface of the magnet 5 is flush with the rear end surface of the limiting block 3 to avoid a rigid collision between the magnet 5 and the front end of the lower mold 1 .

[0037] In another embodiment, in combination Figure 1 and Figure 3 As shown, the elastic layer 6 protrudes from the rear end of the limit block 3. When the lower mold 1 is adsorbed by the magnet 5, the elastic layer 6 plays a buffering role to avoid a rigid collision between the lower mold 1 and the magnet 5 or the limit block 3.

[0038] In another embodiment, if Figure 2 As shown, the workbench 2 is also provided with a pair of guide ridges 16, and the bottom of the lower mold 1 has a guide groove corresponding to the guide ridge, and the guide ridge 16 matches the guide groove.
