Description

 Instruction manual Name of the invention: Cover plate multi-position progressive die

 Technical field

 [0001] The utility model relates to a mold for continuous stamping processing of a cover plate, in particular to a multi-station progressive die for a cover plate.

 Background technique

 [0002] The existing method for producing the cover plate is by stamping, and the production device mainly comprises a punching machine and a mold, that is, a plurality of punches and a specific mold are used to punch out a semi-finished product of a specific shape, and finally the finished product is punched out, so that multiple punches and Multiple sets of matching specific molds are produced in multiple processes. The main processes are: blanking, punching, pressing, bending, shearing, and sizing. If single-step mold production is used, it is not conducive to the positioning of the cover plate, the quality of the punching piece is difficult to guarantee, and the process is cumbersome, the number of molds is large, the labor intensity of the worker is large, and the output is small.

 technical problem

 [0003] The technical problem to be solved by the present invention is to provide a multi-station progressive die with high production efficiency and low production cost for the above prior art.

 Problem solution

 Technical solution

 [0004] The technical solution adopted by the utility model to solve the above problems is as follows: a cover multi-station progressive die, which comprises a lower die base and an upper die base, and is arranged on the lower die base from the bottom from the top a die pad, a die fixing plate, a concave die plate and a guide plate, wherein a convex die pad, a punch fixing plate and a discharge plate are arranged on the upper die holder from top to bottom, in the concave A die hole connected to the die pad, the die fixing plate and the guide plate is arranged on the template from left to right, and corresponding pressing blocks are arranged in the respective die holes, and the punch is fixed The punching plate is matched with the die hole on the concave template from the left to the right, and a top block is disposed in the die hole below the pressing block, and the top block is fixed on the lower die holder. On the ram, a spring is placed on the ram below the top block.

 [0005] Preferably, a guide pin and a lifting pin are disposed between the lower die holder and the upper die holder.

Advantageous effects of the invention Beneficial effect

 [0006] Compared with the prior art, the advantages of the utility model are:

 [0007] The utility model adopts the progressive die production, requires only one mold, and does not need to take and place the workpiece multiple times, can ensure the punching out the qualified cover plate, and achieve the purpose of high efficiency production.

 BEST MODE FOR CARRYING OUT THE INVENTION

 BEST MODE FOR CARRYING OUT THE INVENTION

[0010] The present invention will be further described in detail below with reference to the embodiments of the drawings.

 [0011] As shown in FIG. 1_2, a cover multi-station progressive die in the embodiment includes a lower die holder 1 and an upper die holder 2, and the lower die holder 1 is sequentially disposed from the bottom to the top. There is a die pad 3, a die fixing plate 4, a concave die plate 5 and a guide plate 6, on which the punch pad 7, the punch fixing plate 7 and the unloading are arranged from top to bottom on the upper die holder 2 a material plate 9, on the concave template 5, from the left to the right, a shaping blank hole 10 and a through hole die connected to the die pad 3, the die fixing plate 4 and the guide plate 6 are sequentially arranged. a hole 11, a three-pull punching die hole 12, a two-draw die hole 13, a drawing die hole 14 and a punching die hole 15, in each of the die holes, a corresponding pressing block 16 is disposed. The punch fixing plate 7 is provided with a punch 17 corresponding to the die hole on the concave die plate 5 from the left to the right, and a top block 18 is disposed in the die hole below the press block 16 The top block 18 is placed on the top ram 19 fixed to the lower mold base 1, and a spring 20 is sleeved on the ram 19 below the top block 18, and is disposed between the lower mold base 1 and the upper mold base 2 Guided nail 21 and a lifting pin 22, respectively for aligning the lower die holder 1 and the upper die holder 2, and for adjusting the pressure between the punch and the pressure block.

[0012] The die is completely inlaid, which reduces the processing difficulty and is convenient for maintenance and exchange. In order to prevent the mold from being damaged or even scrapped due to the clogging of the waste and the leakage of the leakage hole, the die edge is designed to be tapered, and the workpiece or scrap is not easy to gather in the die, and the pressure on the edge side is small and the wear is small. In the multi-station progressive die, there are many types of punches, and there are circular punches and profiled punches according to the shape of the cross section. There are punching punches and forming punches according to their functions, which vary in size, length and rigidity. The basic structure and fixing method of the punch are also different. O. 02毫米。 The cover of the double-sided gap is 0. Ol~0. 02 mm. The profiled punch is fast with the platen and the fixed plate Change the fixed, saving the replacement of the day.

 [0013] In addition to the above-described embodiments, the present invention includes other embodiments, and any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
