Abstract
The invention discloses a swaging punch. The punch includes an upper punch and a lower punch, both of which are separable; the upper punch is placed on the lower punch and includes an integrality of an upper strike segment and an upper contact segment, wherein the upper strike segment is located above the upper contact segment with diameter smaller than that of the upper strike segment, and the top of the upper strike segment is a horizontally upper strike surface and the bottom thereof is a horizontally upper contact surface; and the lower punch includes an integrality of a lower strike segment and a lower contact segment, wherein the lower strike segment is located above the lower contact segment with diameter gradually decreasing from top to bottom, the top of the lower strike segment is a horizontally lower strike surface, a contact groove matching with the upper contact segment is arranged on the lower strike surface, and the bottom of the lower contact segment is a horizontally lower contact surface. The invention ensures punch strength via the matching of the upper punch and the lower punch, improves processing depth of punch, and is suitable for processing deep hole.
Description
Technical field
The utility model relates to a kind of drift.
Background technology
Drift is used for punching on press forging.Generally, in order to guarantee the intensity of drift, the length of drift is all shorter; But when the bigger hole of working depth; With after the upper surface of press forging is concordant, steam hammer can't hit down drift again at the scope of attack of drift, and this makes on press forging very difficulty of deep hole processing.If do the length of drift long, not only the intensity of drift reduces, and drift is easy to by towards askew.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of prior art, and a kind of drift that is combined by upper punch and low punch is provided, and it also can be used for deep hole processing when having guaranteed drift intensity.
The purpose of the utility model realizes through following technical scheme:
The forging and pressing drift; It comprises separable upper punch and low punch, and upper punch is positioned on the low punch, and upper punch comprises the upward strike section and the last contact-segment of one; The last section top that is positioned at contact-segment of hitting; The diameter of last contact-segment is less than the last diameter that hits section, and last top of hitting section is the last scope of attack of level, and the bottom of last contact-segment is the last contact-making surface of level;
Low punch comprises the following strike section and following contact-segment of one; The following section of hitting is positioned at the top of contact-segment down; The diameter of following contact-segment reduces from top to bottom gradually; Following top of hitting section is the following scope of attack of level, and the following scope of attack is provided with the groove that contacts with last contact-segment cooperation, and the bottom of following contact-segment is the following contact-making surface of level.
The last strike on section and the periphery that hits section down all is provided with hole for hoist and lifting groove.
The advantage of the utility model is: through the cooperation of upper punch and low punch, when having guaranteed drift intensity, improved the working depth of drift, be suitable for deep hole processing.

Fig. 3 is the overall structure sketch map of the utility model
Among the figure, the 1-upper punch, the 2-low punch, the last strike section of 3-, the last contact-segment of 4-, the last scope of attack of 5-, the last contact-making surface of 6-, 7-hits section down, contact-segment under the 8-, the scope of attack under the 9-, 10-contact groove, contact-making surface under the 11-, the 12-hole for hoist, 13-lifts groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, the protection domain of the utility model is not limited to the following stated.
As depicted in figs. 1 and 2, the forging and pressing drift, it comprises separable upper punch 1 and low punch 2; Upper punch 1 is positioned on the low punch 2; What upper punch 1 comprised one go up to hit section 3 and last contact-segment 4, hits the top that section 3 is positioned at contact-segment 4 with upward, and the diameter of last contact-segment 4 is less than the diameter of last strike sections 3; Last top of hitting section 3 is the last scope of attack 5 of level, and the bottom of last contact-segment 4 is the last contact-making surface 6 of level; Low punch 2 comprises the following strike section 7 and following contact-segment 8 of one; The following section 7 of hitting is positioned at the top of contact-segment 8 down; The diameter of following contact-segment 8 reduces from top to bottom gradually; Following top of hitting section 7 is the following scope of attack 9 of level, and the following scope of attack 9 is provided with last contact-segment 4 cooperates and contacts groove 10, and the bottom of following contact-segment 8 is the following contact-making surface 11 of level.The last strike on section 3 and the periphery that hits section 7 down all is provided with hole for hoist 12 and lifting groove 13.
As shown in Figure 3, after low punch 2 reaches its working depth limit, upper punch 1 is positioned in the contact groove 10 on the low punch 2, the scope of attack 5 is gone up in the steam hammer strike can continue punching.
