Abstract
The utility model provides a cold punching die device. The cold punching die device comprises an upper die and a lower die, and is characterized by a protruding press body is arranged on the lower portion of the upper die, a concave press body is arranged on the lower die, the protruding press body is matched with the concave press body, and a base seat with a fixed clamp is arranged at the lower end of the lower die. The protruding press body is in a half rounded protruding shape. The concave press body is in a half rounded concave shape. The protruding press body is arranged on the lower portion of the upper die, and the concave press body is arranged on the lower die, and furthermore the protruding press body is matched with the concave press body, so that a plate is shaped in one step of cold punching, with a circular arc reasonable in size, and superior to a clip of a welded lug board cut by a pipe fitting. The base seat with the fixed clamp is arranged at the lower end of the lower die, and the lower die is firmly fixed on the base seat by arranging the fixed clamp, and therefore the lower die can not shake easily, so that the cold punching die device rate of finished products is increased, and labor strength and processing cost are reduced. In addition, the cold punching die device is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to the equipments machining die field, relates in particular to a kind of cold punching die device.
Background technology
As everyone knows, the oil-water pipeline in the middle of the petroleum system has all used for many years at present, and most water content of oil wells all reach more than 95%, owing to contain a lot of corrosive substances in the middle of the water quality, constantly corroded pipeline, even initiation perforation phenomenon.Behind the general employing same specification pipe fitting cutting certain size, add the weldering otic placode on both sides and serve as leak stoppage checkpost, this original processing mode, the problems such as existence is wasted time and energy, complex process, product quality is low, organization of production is difficult.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of cold punching die device, comprise upper die and lower die, the bottom that it is characterized in that described patrix is provided with protruding laminate, described counterdie is provided with recessed laminate, protruding laminate and recessed laminate are complementary, and described counterdie lower end is provided with the base with fixing hoop.
Described protruding laminate is half round convex shape.
Described recessed laminate is half round concave shape.
The beneficial effects of the utility model are: the patrix bottom is provided with protruding laminate, be provided with recessed laminate on the counterdie, protruding laminate and recessed laminate are complementary, make plate cold punching once-forming, arc size is reasonable, the clamp that is better than the weldering otic placode of pipe fitting cutting, the counterdie lower end is provided with the base with fixing hoop, the setting of fixing hoop can be firmly fixed on the base counterdie more, make counterdie in process, be difficult for rocking, thereby improve yield rate, reduce labour intensity and processing cost, the utility model is simple in structure, convenient operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1-patrix, 2-counterdie, the protruding laminate of 3-, the recessed laminate of 4-, 5-fixing hoop, 6-base.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details;
As shown in Figure 1, be respectively arranged with protruding laminate 3 and recessed laminate 4 on the bottom of patrix 1 and the counterdie 2, protruding laminate 3 is complementary with recessed laminate 4, and counterdie 2 lower ends are provided with the base 6 with fixing hoop 5.Described protruding laminate 3 is half round convex shape.Described recessed laminate 4 is half round concave shape.
During use, patrix 1 is connected with hydraulic head, base 6 and hydraulic press working face are fixed, processed clamp stock is placed on the recessed laminate 4 of counterdie 2, the wall thickness according to the different size pipeline has calculated size, adopt the steel plate of identical wall thickness, the driving hydraulic press is descending, the pressurization so that the semicircle working face of patrix 1 and counterdie 2 cooperatively interacts, and the clamp stock of processing is the cold punching once-forming just.
