Abstract
The utility model relates to a punch assembly with longer service life, which comprises a splint insert; the clamping plate insert is provided with a longitudinal punch, a first positioning groove matched with the punch, a transverse round positioning pin and a second positioning groove matched with the round positioning pin and communicated with the first positioning groove; an arc-shaped third positioning groove is formed in the side surface of the punch; the third positioning groove is matched with the outer circular surface of the round positioning pin. During the use, wear the drift earlier to the splint and go into the first constant head tank of son, and then, wear the circular locating pin in the second constant head tank, then circular locating pin and drift laminating, and the binding face is the arc, and under the identical condition completely, the drift can bear bigger impact force and pulling force in stamping process, difficult fracture, and life is longer.
Description
Technical Field
The utility model relates to a drift technical field, more specifically say, relate to a longer drift subassembly of life.
Background
When the punch is installed, clamping plate inserts and buckles are often needed. Fig. 4 and 5 show an irregularly-shaped punch, wherein a fastener is square, the side surface of the punch is correspondingly provided with a step with the depth of 1MM, but the punch is easy to break at the step when the product is thicker or harder due to sharp corners at two ends of the step. Therefore, there is still a need for improvement of the existing structure to solve the above-mentioned disadvantages.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in, to the above-mentioned defect of prior art, a longer drift subassembly of life is provided.
The utility model provides a technical scheme that its technical problem adopted is:
constructing a longer life punch assembly including a splint insert; the clamping plate insert is provided with a longitudinal punch, a first positioning groove matched with the punch, a transverse round positioning pin and a second positioning groove matched with the round positioning pin and communicated with the first positioning groove; an arc-shaped third positioning groove is formed in the side surface of the punch; and the third positioning groove is matched with the outer circular surface of the circular positioning pin.
Preferably, the clamping plate insert is provided with a bolt with the tail end facing the round positioning pin and a threaded hole matched with the bolt; four groups of rubber limiting bulges which are uniformly distributed on the circumference are fixedly arranged at the tail end of the bolt; the distribution circle of the rubber limiting bulges is coaxial with the bolt.
Preferably, the rubber limiting protrusion is fixedly bonded with the bolt.
The beneficial effects of the utility model reside in that: during the use, wear the drift earlier to the splint and go into the first constant head tank of son, and then, wear the circular locating pin in the second constant head tank, then circular locating pin and drift laminating, and the binding face is the arc, and under the identical condition completely, the drift can bear bigger impact force and pulling force in stamping process, difficult fracture, and life is longer.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, a clear and complete description will be given below with reference to the technical solutions of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
A longer life punch assembly of the preferred embodiment of the present invention is shown in fig. 1-3, and includes a clamp plate insert 10; the splint insert 10 is provided with a longitudinal punch 11, a first positioning groove 180 matched with the punch 11, a transverse round positioning pin 12 and a second positioning groove 181 matched with the round positioning pin 12 and communicated with the first positioning groove 180; the side surface of the punch 11 is provided with an arc-shaped third positioning groove 182; the third positioning groove 182 fits the outer circumferential surface of the circular positioning pin 12. During the use, wear the drift 11 earlier in the first constant head tank 180 of splint income sub 10, and then, wear second constant head tank 181 with circular locating pin 12 in, then circular locating pin 12 and drift 11 laminating, and the binding face is the arc, and under the identical condition completely, drift 11 can bear bigger impact force and pulling force in the punching press process, and difficult fracture, life is longer.
As shown in fig. 1-2, the splint insert 10 is provided with a bolt 13 with a tail end facing the circular positioning pin 12, and a threaded hole 183 adapted to the bolt 13; four groups of rubber limit bulges 14 which are uniformly distributed on the circumference are fixedly arranged at the tail end of the bolt 13; the distribution circle of the rubber limiting protrusions 14 is coaxial with the bolt 13, the bolt 13 is screwed after the rubber limiting protrusions 14 penetrate through the round positioning pin 12, the round positioning pin 12 is pushed towards the punch 11, the round positioning pin 12 is attached to the punch 11 more tightly, and the rubber limiting protrusions 14 can prevent the round positioning pin 12 from being damaged by pushing.
As shown in FIG. 2, the rubber limit protrusion 14 is fixedly bonded with the bolt 13, so that the connection is stable and the cost is low.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
