Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] A punching die for punching parts with various specifications of hexagonal holes according to the present invention mainly includes a main body mechanism, a positioning mechanism, a discharge mechanism and a punch 7 . Wherein the main body mechanism includes a backing plate 1 and a lower formwork 2, both of which are connected together by positioning pins 13 and screws 14. The main structure is fixed on the stamping machine and connected to other mechanisms. The positioning mechanism is made up of fixed block 3, sliding block 9, positioning block (4,8), bearing 11, pull rod 12, spring 10, handle 22, through positioning pin (18,20,21) and screw (17,19) The composition is fixed on the main structure, which plays the role of fixing the parts to be processed. The unloading mechanism is composed of a support frame 5 and a discharge stopper 6, which are fixed on the...

The invention discloses a punching mold for punching hexagonal hole parts with multiple specifications, and belongs to the field of machining of the hexagonal hole type parts. The punching mold is particularly suitable for machining the hexagonal hole parts which has small machining batch, multiple types and relatively high requirements and precision. Specifically, three replaceable structures areadopted to meet machining of the hexagonal hole parts with the multiple specifications; firstly, special clamp blocks are used for the parts with the different specifications to achieve the purpose of fixing the parts to be machined, so that clamping of the parts with different diameters is achieved, and for the parts with different heights, the modes that cushion blocks are used below the parts,and the heights of the cushion blocks are adjusted are used so as to meet the machining requirements of the parts with the different heights; secondly, the punching process of the parts is carried out, namely, the design structure that the punch working part can be replaced is adopted in the design of a punch so as to meet the punching machining of the hexagonal hole parts with the different specifications and sizes; and finally, after hexagonal holes are punched, a part withdrawing device is further arranged in order that the parts can be separated from the punch, the part withdrawing devicecooperates with the punch for use so as to achieve the part withdrawing effect.
Description
technical field [0001] The invention belongs to the field of hexagonal-hole parts processing, and is particularly suitable for processing hexagonal-hole parts with small batch size, many types and relatively high precision. Background technique [0002] Hexagon socket screws are widely used in aviation, aerospace, shipbuilding, electronics, defense and other fields due to their good positioning and loosening effect. Due to the wide application of hexagon socket cap screws, it is necessary to ensure the uniformity and interchangeability of hexagon socket cap products of the same specification when manufacturing hexagon socket cap screws. Therefore, when manufacturing such products, molds should be used to ensure. In the design process of some products, in order to ensure the specificity of the hexagon socket head cap screws, non-standard size hexagonal hole punching dies with unknown specifications will be used to meet the production requirements. [0003] Due to the partic...
