Abstract
The utility model relates to a part of a forging mold, in particular to a novel forging punch, which comprises a punch-holder shank and a shank end, wherein the shank end has an inward tilting taper, and a key groove matched with a punch fixing flange is formed in the middle of the shank end. According to the novel forging punch, because the key groove has positioning and clamping effects, the time for mold changing personnel to correct the center of the punch and the forging mold can be saved, and the novel forging punch cannot be rotated in the process of production. Additionally, because the shank end has the taper, the novel forging punch is tighter and tighter in the process of tightening, the punch is not easy to loose during production, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of parts of forging mold, relates in particular to a kind of novel forging punches.
Background technology
At present, forging the drift pommel of installing on pusher side cylinder axle is full circle shape.More time-consuming when drift is installed, need carefully to proofread the center with the forge mould die cavity, and can produce after tightening.But what do due to drift in production process is drawing and pulling type running, therefore friction is larger, occur after causing drift easily loosening eccentric, the phenomenon such as spin.Make the easy fracture of its drift, greatly reduce its service life.
The utility model content
Defective and deficiency that the utility model exists in order to solve above-mentioned prior art provide a kind of easy for installation, solid and reliable, the novel forging punches of long service life.
The technical solution of the utility model: a kind of novel forging punches, comprise punch-holder shank and pommel, described pommel is provided with intilted tapering the keyway that coordinates the drift mounting flange in the middle part of pommel.
Preferably, the formed acute angle of tapering on described pommel is 15 °-18 °.
Preferably, the wide 6mm of the keyway that arranges on described pommel, dark 8mm.
The utility model has played the effect of location screens due to keyway, just can save the die change personnel proofreads the time at center its drift and forge mould, can not spin in process of production yet, simultaneously because pommel is with tapering, therefore in the process that tightens be more go up tighter, drift also should not become flexible when producing, and also be improved service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1. punch-holder shanks in figure, 2. pommel, 3. keyway.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing, but be not the restriction to the utility model protection domain.
As shown in Figure 1, a kind of novel forging punches comprises punch-holder shank 1 and pommel 2, and pommel 2 is with intilted tapering, and the formed acute angle of the tapering on pommel is 17 °, and pommel 2 middle parts are provided with the keyway 3 that coordinates the drift mounting flange, the wide 6mm of keyway, dark 8mm.
The utility model has played the effect of location screens due to keyway, just can save the die change personnel proofreads the time at center its drift and forge mould, can not spin in process of production yet, simultaneously because pommel is with tapering, therefore in the process that tightens be more go up tighter, drift also should not become flexible when producing, and also be improved service life.
