Abstract
The utility mode discloses a combination-type punch of a numerical control punch press die. The combination-type punch of a numerical control punch press die is simple in structure and convenient to install, and a punch core is replaced conveniently. The combination-type of the numerical control punch die comprises a die handle and the punch core. Big-end-down step holes are formed on the bottom of the die handle, a big-end-down step shaft is placed on the top of the punch core, an internal thread is placed in a small step hole of the die handle, an external thread is formed in a small step circle of the punch core, and the small step hole of the die handle is connected with the small step circle of the punch core through a thread. A large step hole of the die handle is matched with a large step circle of the punch core. An existing integral-type punch of a numerical control punch press die is divided into a die handle and a punch core, and the die handle and the punch core are made of different materials. The threaded connection and step hole positioning are applied, so that the positioning is accurate, and the structure is reliable. Corresponding pin holes are formed, and the reliability of connection is further increased. The defect that the integral-type punch of the numerical control punch press die is high in cost is overcome, and the punch and the punch core are replaced easily and conveniently.
Description
Technical field
The utility model relates to the improvement to punch structure in the numerical control mould.
Background technology
Existing numerical control punch die drift mostly is solid punch greatly, and after the cutting edge wearing and tearing of drift bottom, whole drift is scrapped and can not be used, the drift that need more renew.Because the material of drift is high-speed tool steel, the manufacturing cost height, thereby cause very big waste, be unfavorable for reusing.
The utility model content
The utility model provides a kind of simple in structure at above problem, is convenient to change towards core and the convenient numerical control punch die combined type drift of installing.
The technical solution of the utility model is: comprise die shank and towards core, the bottom of described die shank is provided with up-small and down-big shoulder hole, described top towards core is up-small and down-big multidiameter; Be provided with internal thread in the small stair hole of described die shank, described small stair circle towards core is provided with external screw thread, and the small stair hole of described die shank is threaded with the flexible mistake of described small stair towards core, and the big stepped hole of described die shank and described big step towards core are justified suitable.
Also be provided with vertical on the described die shank and through the pin-and-hole one in described small stair hole, described small stair circle towards core is provided with the pin-and-hole two corresponding with described pin-and-hole one.
The utility model will have numerical control punch die monoblock type drift now, be divided into die shank and towards core two parts, both can adopt different materials to make.Employing is threaded and stepped hole location, makes accurate positioning, reliable in structure; Corresponding pin-and-hole is set, has further increased the reliability that connects.The utility model has overcome the use cost height of numerical control punch die monoblock type drift, and changes drift simple to operation towards core.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is die shank among the figure, the 11st, and the small stair hole, the 12nd, pin-and-hole one, 13rd, big stepped hole, the 2nd, towards core, the 20th, pin-and-hole two.
The specific embodiment
The utility model comprises die shank 1 and towards core 2, the bottom of described die shank 1 is provided with up-small and down-big shoulder hole as shown in Figure 1, and described top towards core 2 is up-small and down-big multidiameter; Be provided with internal thread in the small stair hole 11 of described die shank 1, described small stair circle towards core 2 is provided with external screw thread, the small stair hole of described die shank 1 is threaded with the flexible mistake of described small stair towards core, the big stepped hole 13 of described die shank 1 and described big step circle towards core 2 are suitable, in the real work, convenient location connects reliable.
Also be provided with vertical on the described die shank 1 and through the pin-and-hole 1 in described small stair hole 11, described small stair circle towards core 2 is provided with the pin-and-hole two 20 corresponding with described pin-and-hole 1, and pin connects and further improved the reliability that connects.
