Description

Die for stamping small-size groove-shaped part

Technical Field

The utility model belongs to the technical field of the guided missile weapon system part is made and specifically relates to a mould that is used for punching press of small dimension cell type spare.

Background

The bent edge groove type reinforcing part is an important component structural part in the missile weapon system and has the function of reinforcing and protecting an external protection part of the missile weapon system. Missile weapon systems have strict requirements on the shape and size of various components. The dimensional tolerance of the opening edges at the two ends of the groove-shaped reinforcing piece is strict. The side length also influences the size range of the part matched with the groove-shaped reinforcer because the side length is related to the bearing condition of the reinforcing effect. The radian requirements of two top corners of the groove-shaped reinforcing part are strict, and complete stamping and accurate stamping are required. The angle and the arc length of the arc influence the force bearing distribution condition of the groove-shaped reinforcing part, and the irregular arc can cause stress concentration. The stamping is formed in one step, and the position cannot be adjusted in the stamping process, so that the stamping blank must be placed stably and perfectly. The mould must be easy to load, and the piece to be pressed is placed on the mould completely at one time. Therefore, it is necessary to design a die for stamping the small-sized bent-edge groove-shaped reinforcing part.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mould for punching press of small dimension cell type spare in order to solve the defect that prior art exists.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

a die for stamping small-specification groove-shaped parts comprises an upper pressure head die and a falling die, wherein the upper pressure head die comprises an upper pressure plate and a pressure head fixed on the upper pressure plate, and the end part of the pressure head is provided with a pressure applying surface;

the falling die comprises a base and a forming groove arranged on the base, wherein the middle part of the forming groove is provided with a forming surface, and two sides of the forming groove are provided with limiting surfaces.

Further, the molding surface is positioned right below the pressure applying surface and corresponds to the pressure applying surface.

Further, the width of the forming groove is larger than that of the pressing head, and the forming surface is positioned at the bottom of the forming groove.

Furthermore, the forming groove is U-shaped, and two sides of the bottom of the forming surface are provided with arc surfaces.

Furthermore, both sides of the bottom of the pressure head are provided with arc-shaped surfaces.

Further, the rib of the pressure head is connected with the upper pressure plate through a plurality of supporting plates.

The utility model has the advantages that: the die can accurately stamp the C-shaped reinforcing piece with the bent edge. Due to the unique structural design of the die, the position of the die does not need to be adjusted after the pressing piece is placed on the die, and the stamping operation time is shortened. The structure can fix the pressing piece, and the punching is smoothly carried out, so that the accurate punching is realized. The design of the forming groove on the lower die enables the stamping upper part to be simple and convenient, and the processing efficiency is improved. The limiting surface of the die has the function of detecting the size of the piece to be pressed, so that the product quality is better controlled, and the yield of the bent edge groove type reinforcing piece is improved.

Detailed Description

As shown in fig. 1 to 3, the die for punching the small-size groove-shaped part comprises an upper pressing head die 1 and a falling die 2, wherein the upper pressing head die 1 comprises an upper pressing plate 11, a pressing head 12 fixed on the upper pressing plate 11, and the end part of the pressing head 12 is provided with a pressing surface 13; the ribs of the ram 12 are connected to the upper platen 11 by a plurality of support plates 15.

The drop type die 2 comprises a base 21 and a forming groove 22 arranged on the base 21, wherein the middle part of the forming groove 22 is provided with a forming surface 23, and two sides of the forming groove 23 are provided with limiting surfaces 24.

The molding surface 23 is located right below the pressing surface 13 and corresponds to the pressing surface 13. The forming groove 22 has a groove width greater than the width of the ram 12 and the forming surface 23 is located at the bottom of the forming groove 22.

Further, the forming groove 22 is U-shaped, and two sides of the bottom of the forming surface 23 are provided with arc surfaces 25. The bottom of the ram 12 is flanked by arcuate surfaces 14. The planar dimensions of the pressing surface 13 and the radius of the arc-shaped surface 14 are determined by the external dimensions of the edge-groove-type reinforcement to be pressed.

The die is a one-step forming die, and the piece to be pressed can be formed by one-step complete stamping on the die. The mold is assembled to a mating molding machine. Proper occlusion must be tested during the assembly of the upper and lower molds. The casting die is a preliminary working piece stamped in a previous process, the casting die is a C-shaped reinforcing piece with a bent edge, the whole casting die is in a long strip shape, and the height of the bent edge determines the depth of the forming groove 22 of the die.

During processing, the pressing piece is placed in the forming groove 22 stably, the pressing piece is attached to the falling die 2, two ends of the pressing piece are in contact with the limiting surfaces 24 at two ends of the falling die 2 respectively, the matching is good, the limiting surfaces 24 limit the pressing piece, and the falling die 2 can stably fix the pressing piece. During processing, the pressing head 12 moves downwards to press the part to be pressed, and after complete pressing, the part to be pressed is completely attached to the forming surface 23 of the falling die 2. And maintaining the pressure for a certain time to obtain the bent edge groove type reinforcement product with accurate size. Due to the special design of the limiting surface 24, the part to be pressed can be clamped, so that the punching is smoothly carried out, and the position of the part to be pressed does not need to be adjusted in the punching process.

The die can accurately stamp the C-shaped reinforcing piece with the bent edge. Due to the unique structural design of the die, the position of the die does not need to be adjusted after the pressing piece is placed on the die, and the stamping operation time is shortened. The structure can fix the pressing piece, and the punching is smoothly carried out, so that the accurate punching is realized. The design of the forming groove on the lower die enables the stamping upper part to be simple and convenient, and the processing efficiency is improved. The limiting surface of the die has the function of detecting the size of the piece to be pressed, so that the product quality is better controlled, and the yield of the bent edge groove type reinforcing piece is improved.
