Abstract
The utility model relates to a double dovetail groove hammerhead which comprises a hammer body (1), a guide rail groove (2), an inner taper sleeve (3) and a lower dovetail groove (4). The double dovetail groove hammerhead is characterized in that the hammer body (1) is provided with a straight hole (5) inside, an upper dovetail groove (6) is arranged above the straight hole (5), and the upper dovetail groove (6) is the same as the lower dovetail groove (4), the inner taper sleeve (3) is provided with a stop opening (7) or the lower end of the inner taper sleeve (3) is provided with a locating sleeve (8). Due to the addition of the dovetail groove, the double dovetail groove hammerhead prolongs the service life of the hammerhead, saves steel material and reduces the machining process time.
Description
Technical field
The utility model belongs to the forging equipment technical field, a kind of double swallow tailed groove tup.
Background technology
At present, forging equipment is a rectangular structure with tup on the whole, about face have guide-track groove, cooperate with the column slideway; Lower plane has dovetail groove, and dovetail groove cooperates with last anvil piece dovetail, with key both is located, with carving iron with both jam-packeds; The center boring of tup has shoulder hole, and interstitial hole is installed inner conical drogue, and tup is exactly to cooperate with hammer stem by inner conical drogue, forms to hit parts.This tup is fragile, and main cause is that dovetail groove transition circle edged surface exists the processing tool marks, forms stress and concentrates; Another reason is in the process of carving the iron jam-packed, because repeatedly bump and the frequent anvil piece that replaces with form fatigue crack at dovetail groove fillet place.The method of avoiding is to improve the machined fineness of knuckle, avoids producing tool marks; Reduce the number of times that replaces with the anvil piece, avoid fatigue crack.But along with the continuous increase of object output and improving constantly of quality, to the also further raising of flatness requirement of last anvil piece lower plane, the frequency that therefore replaces with the anvil piece is higher, and fatigue crack is difficult to avoid.
Summary of the invention
Goal of the invention of the present utility model provides a kind of tup double swallow tailed groove tup in service life that prolongs.The technical scheme that realizes the present utility model purpose is: the utility model includes hammer body, guide-track groove, inner conical drogue and following dovetail groove, it is characterized in that having in the hammer body straight hole, the straight hole top is provided with dovetail groove, and last dovetail groove is identical with following dovetail groove, and said inner conical drogue is provided with seam or the lower end of inner conical drogue is provided with positioning sleeve.
The utility model is owing to be double swallow tailed groove hammer, and the commutative use of two dovetail grooves, prolongation are known clearly service life of tup, have saved steel, and have reduced machining time.
Description of drawings
Fig. 1 is the structural representation of the utility model band seam; Fig. 2 is the structural representation of the utility model band positioning sleeve.Among the figure, 1, hammer body, 2, guide-track groove, 3, inner conical drogue, 4, dovetail groove down, 5, straight hole, 6, go up dovetail groove, 7, seam, 8, positioning sleeve.
The specific embodiment
With reference to accompanying drawing, the utility model includes hammer body 1, guide-track groove 2, inner conical drogue 3 and following dovetail groove 4, it is characterized in that having in the hammer body 1 straight hole 5, and the top of straight hole 5 is provided with dovetail groove 6, and last dovetail groove 6 is identical with following dovetail groove 4, and said inner conical drogue 3 is provided with seam 7.Or the lower end of inner conical drogue 3 is provided with positioning sleeve 8.
When using the utility model, inner conical drogue 3 is installed in the straight hole 5 of hammer body 1, the sheet copper that adds 1 millimeters thick carries out tup and installs, after dovetail groove 4 goes wrong down, can withdraw from inner conical drogue 3, hammer body 1 is turned around, inner conical drogue 3 is installed in straight hole 5, change the sheet copper of 1 millimeters thick, can install and re-use, use identical with single dovetail tup.
Claims (2)
1. double swallow tailed groove tup, include hammer body (1), guide-track groove (2), inner conical drogue (3) and following dovetail groove (4), it is characterized in that having in the hammer body (1) straight hole (5), the top of straight hole (5) is provided with dovetail groove (6), and last dovetail groove (6) is identical with following dovetail groove (4), and said inner conical drogue (3) is provided with seam (7).
2,, it is characterized in that being provided with under the said inner conical drogue (3) positioning sleeve (8) according to the said double swallow tailed groove tup of claim 1.
