Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model aims at providing a forge ejector pin anti loosening structure for die carrier to solve the problem that above-mentioned prior art exists, the long-term stability of ejecting system can be guaranteed to this structure.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
The first embodiment is as follows:
as shown in fig. 1 to 3, the embodiment provides an anti-loose structure for a top rod of a forging die set, which is suitable for an ejection system of a main die holder on the forging die set. The ejector rod anti-loosening structure for the forging die set comprises a pin 1, a reset top plate 2, a spring 3 (serving as an elastic reset piece), an upper main die base 4 and an upper ejector rod 5. As shown in fig. 2, the reset top plate 2 includes a plate portion 21 and a rod portion 22 connected below the plate portion 21, the rod portion 22 is provided with a coarse thread, and a center hole at the top end of the upper top rod 5 is provided with a coarse thread to realize a threaded connection with the reset top plate 2. In the present embodiment, a double fixing method is adopted, that is, in addition to the above direct screwing method, the plate portion 21 is connected with the top end surface of the upper push rod 5 through the pin 1, specifically: and pin grooves with internal threads are drilled at the positions corresponding to the top end surfaces of the plate part 21 and the upper ejector rod 5, and the pins 1 sequentially penetrate through the pin grooves of the plate part 21 and the upper ejector rod 5 and are screwed, so that the plate part 21 and the upper ejector rod 5 are tightly connected.
When the device works, the upper ejector rod 5 is firstly assembled and inserted into the assembling hole 6 of the upper main die holder 4; then the spring 3 is sleeved on the upper ejector rod 5, and the spring 3 is positioned in the reset piece mounting space 7; and finally, the reset top plate 2 is arranged at the top of the upper ejector rod 5 in the connection mode. Wherein, piece installation space 7 that resets takes shape in pilot hole 6, and piece installation space 7 that resets forms through the reaming mode, and the internal diameter is greater than the former diameter of pilot hole 6 to make and form the step hole structure in whole pilot hole 6, the bottom of piece installation space 7 that resets is formed with the shaft shoulder structure, is favorable to providing effectual holding power to the spring bottom when the spring is compressed. Meanwhile, the plate portion 21 has an outer diameter larger than that of the upper stem 5, facilitating effective pressing of a spring outside the upper stem 5. It can be known from the foregoing, this embodiment adopts the preferred shaft shoulder structure that has adopted as the support of spring bottom, and in actual operation, can also adopt other modes according to actual conditions, for example with spring bottom snap-on at the 6 inner walls of pilot hole, or through set up radial bracing piece (board) at the 6 inner walls of pilot hole, with the spring directly place the top at radial bracing piece can, when the spring was compressed, the bracing piece plays bottom supporting effect.
As shown in fig. 3, the upper top plate 8 is pressed down to drive the upper post rod 5 to move downwards, and the spring 3 is compressed between the plate part 21 and the bottom shoulder (spring bottom end support) of the reset piece installation space 7 under the action of the plate part 21; when the upper top plate 8 returns to the original position, the spring 3 drives the upper mandril 5 to move upwards. In the whole working process, the reset top plate 2 is fastened on the upper ejector rod 5, the screwing state between the reset top plate 2 and the upper ejector rod 5 is ensured through the threaded connection and the matching pin connection, and meanwhile, the upper top plate 8 can be ensured not to be loosened. It should be noted that, as is obvious to a person skilled in the art, the invention is not limited to details of the above-described exemplary embodiments, but can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
The utility model discloses a concrete example is applied to explain the principle and the implementation mode of the utility model, and the explanation of the above example is only used to help understand the method and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.
