Description
Technical field
The utility model relates to screw processing structure technical field, refers in particular to a kind of flat head screw stationary rivet die lamps structure.
Background technology
Along with science and technology and economic fast development, there is various plant equipment, and the use of these equipment, also promote science and technology and expanding economy.The mode of screw or screw connection is usually taked in the connection of plant equipment, and it is quick for installation, and can dismantle, so very convenient when needs amendment and replacing.
Flat head screw, has generally comprised a screw body, and the axial plane of screw body is formed with axially extended thread, and is provided with at its tail end and at least onely cuts groove.As shown in Figure 1, there is a PO pin to the stationary rivet die lamps structure of the processing of flat head screw now, wherein PO pin uses with movable stamping die benevolence matched in clearance, during head by the pre-upsetting flat head screw of this structure cold-heading, easily there is overlap in head end, not only affect the outward appearance of product, reduce the die life of subsequent work stations, even easily cause activity to be rushed stuck, cause the situation of burn failure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of flat head screw stationary rivet die lamps structure that can reduce costs, effectively improve the quality of products.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of flat head screw stationary rivet die lamps structure, include movable punching and punch die shell, described punch die valve jacket is located at the outer surface of movable punching, is embedded with movable stamping die benevolence in the head of described activity punching, described movable stamping die benevolence offers pore, pads after the afterbody that described activity is rushed is connected with male model.
Wherein, the afterbody padded after described male model is arranged with spring, and described spring pads between punch die shell after male model.
Wherein, the cross section of described pore is in " L " type.
Wherein, the end face of described movable stamping die benevolence offers chamfering die cavity.
The beneficial effects of the utility model are:
A kind of flat head screw stationary rivet die lamps structure described in the utility model, by offering pore in movable stamping die benevolence, the utility model is sold without the need to using PO, can effectively reduce costs, and when the pre-heading portion of cold-heading, the head end of product can be made smooth, not only effectively increase the aesthetic property of product, and improve service life of the present utility model further.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of flat head screw stationary rivet die of the utility model lamps structure.
Reference numeral:
1---movable punching 2---punch die shell
3---movable stamping die benevolence 4---pore
5---spring 6---chamfering die cavity
11---pad after male model.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
As shown in Figure 1, a kind of flat head screw stationary rivet die lamps structure described in the utility model, include movable punching 1 and punch die shell 2, described punch die shell 2 is sheathed on the outer surface of movable punching 1, movable stamping die benevolence 3 is embedded with in the head of described activity punching 1, described movable stamping die benevolence 3 offers pore 4, and the afterbody of described activity punching 1 is connected with pad 11 after male model.
The utility model provides a kind of flat head screw stationary rivet die lamps structure, by offering pore 4 in movable stamping die benevolence 3, the utility model is sold without the need to using PO, can effectively reduce costs, and when the pre-heading portion of cold-heading, the head end of product can be made smooth, not only effectively increase the aesthetic property of product, and improve service life of the present utility model further.
Wherein, the afterbody padding 11 after described male model is arranged with spring 5, and described spring 5 pads between 11 and punch die shell 2 after male model.
In the utility model, after described male model, pad the sheathed spring 5 of afterbody of 11, when padding 11 after male model and carrying out the pre-upsetting of punching press, reset condition can be automatically replied timely, make the utility model be not easy to be stuck, effectively promote service life of the present utility model.
As preferred embodiment, the cross section of described pore 4, in " L " type, can strengthen practicality of the present utility model further.
Further, the end face of described movable stamping die benevolence 3 offers chamfering die cavity 6.In the utility model, the end face of described movable stamping die benevolence 3 offers chamfering die cavity 6, and when avoiding cold-heading pre-upsetting product, burr appears in its head, to such an extent as to follow-up needs increases the operation of deburring, and the utility model effectively saves manufacturing procedure, improves production efficiency.
Above-described embodiment is the utility model preferably implementation, and in addition, the utility model can also realize by alternate manner, and under the prerequisite not departing from the technical program design, any apparent replacement is all within protection domain of the present utility model.
