Detailed Description
The present invention will be further explained below.
Example 1: referring to fig. 1, 2 and 3, a valve mica sheet mould pressing tool comprises a tool table top 4, wherein a mould pressing machine 1, an upper mould 2 and a lower mould 3 are arranged on the tool table top 4, a guide rod 10 is arranged between the upper mould 2 and the lower mould 3, the lower mould 3 is fixed on the tool table top 4, a groove matched with a valve mica sheet 9 is formed in the bottom surface of the upper mould 2, a male mould 5 and a top plate 6 are arranged on the lower mould 3, a boss 51 matched with the groove is arranged on the male mould 5, a through hole 62 matched with the boss 51 is formed in the top plate 6, a buffer mechanism 7 is vertically arranged between the top plate 6 and the lower mould 3, and a limiting protection tool 8 for limiting the pressing position of the upper mould 2 is arranged between the upper mould 2.
Because the whole mica sheet is punched, if the mica sheet is directly pressed, even if parts are molded, the rest rim charge sheets are crushed by pressing, the picking is not easy, and the sheets are damaged greatly. Therefore, the male die 5 and the top plate 6 with the buffering function are designed, the grooves and the bosses 51 on the male die 5 are designed according to the structural design of the valve mica sheets 9, in the pressing process of the upper die 2, the valve mica sheets 9 are pressed and formed between the grooves and the bosses 51, the rest of the sheets are buffered due to the design of the buffering top plate 6, the sheets can be separated from the valve mica sheets 9, the sheets can be protected from being crushed, and one sheet can be pressed with a plurality of valve mica sheets 9. Greatly reduces the waste and the cost. And the punching is convenient and quick, and the simple polishing can be completed after the punching. The production efficiency is greatly improved. In addition, the design of the buffer top plate 6 also facilitates material returning of the sheet, and after punching is completed, the buffer spring 72 is recovered, so that the sheet can be jacked up, and the sheet can be taken out conveniently.
Buffer gear 7 comprises guide bar 71 and buffer spring 72, guide bar 71 sets up around terrace die 5, and the lower extreme of guide bar 71 welds on frock mesa 4, seted up on roof 6 with guide bar 71 assorted guiding hole 61, buffer spring 72 suit is on guide bar 71, and is located between roof 6 and the lower mould 3, realizes the buffering operation of roof 6 in the lower mould 3 pressing process through buffer spring 72, and guide bar 71 plays the effect of location direction at roof 6 lift in-process.
Through changing the buffer spring 72 of different length, ensure that the upper table surface of boss 51 is located the through-hole 62 of roof 6 when buffer spring 72 is uncompressed, its effect lies in, pushes down the in-process at lower mould 3, and roof 6 can not block at the upper table surface of boss 51, and in the process that lower mould 3 rises, buffer spring 72 return can jack-up roof 6, and the surplus sheet on the roof 6 also can the level move away simultaneously, does not receive the restriction of boss 51 position.
For avoiding causing valve mica sheet 9 damaged in the punching process, spacing protection frock 8 has been designed, spacing protection frock 8 comprises cushion 82 and stopper 81, weld on frock mesa 4 bottom cushion 82, the vertical screw rod 84 that is equipped with in cushion 82 top, stopper 81 is strip and front end for the wedge, stopper 81 rear end is vertical seted up with screw rod 84 assorted screw 83, stopper 81 is fixed in cushion 82 top through fastening nut 85 with screw rod 84 assorted. When the lower die 3 is pressed down, the pressing is stopped when the lower die is pressed onto the limiting block 81, the interval between the upper die 2 and the lower die 3 is adjustable by adjusting the entering and exiting amount of the wedge-shaped part of the limiting block 81, and the height of the pressing position of the lower die 3 is limited. The limiting block 81 needs to be adjusted and adjusted during punching and a test is carried out until the requirement is met, and then a finished product can be pressed. The yield of the valve mica sheets 9 in the punching process is greatly improved. The two limit protection tools 8 are generally arranged on the left side and the right side of the lower die 3 symmetrically.
Screw 83 is the bar hole, the bar hole sets up along stopper 81 length direction, and the screw 83 of bar can be used to adjust the volume of advancing that stretches out of the wedge position of stopper 81, is convenient for adjust the height that pushes down of lower mould 3. The adjustment can be realized by loosening the fastening nut 85, the fixation can be realized by tightening the fastening nut 85, and the limiting block 81 can be rotated away when not needed. The operation is convenient and fast.
The wedge position of stopper 81 is located between last mould 2 and the lower mould 3, and stopper 81 bottom surface and lower membrane upper surface parallel and level through lower mould 3 and the atress of frock mesa 4, can not rock from top to bottom because of leading to stopper 81 at the suppression process.
The mould pressing tool for the shutter mica sheets provided by the utility model is introduced in detail, and the principle and the implementation mode of the utility model are explained by applying a specific example, and the explanation of the above embodiment is only used for helping to understand the method and the core idea of the utility model; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
