Abstract
The utility model discloses a recessed terrace die and particularly relates to a recessed terrace die used for car body front floor parts. The recessed terrace die can effectively avoid cracking and prevent a crack from being formed at the recessed portion of a product. The die comprises a groove formed in the middle of the upper end of the recessed terrace die. The recessed terrace die is of a split structure segmented from the position of the groove. Due to the fact that the recessed terrace die adopts the split structure. In the production process, when the recessed terrace die tends to crack in an expansion mode under the effects of double side pressure and material flowing in, the recessed terrace die can be separated automatically, and scrapping of the recessed terrace die caused by expansion cracking is avoided.
Description
Technical field
The utility model relates to a kind of concave punch, especially a kind of concave punch for front floor of automobile body part.
Background technology
In the part present situation of the front floor of body part, part is middle recessed shape, in front floor drawing die at home and abroad, concave punch employing traditional structure is the punch of integral type, but owing to being subject to part self shape and process limitation, concave punch is in process of production owing to being subject to the two-sided lateral pressure of patrix and the impact that material flows into, cause concave punch cracking, so not only can make mould scrap, and the part of producing also can be due to crack of die in recessed generation crack, position, therefore also there is no in the prior art can effectively avoid in process of production the concave punch of cracking.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of can effectively avoiding and ftractures, and prevents that product is at the concave punch in generation crack, concave part.
For solving the problems of the technologies described above the concave punch of the utility model employing, comprise groove, described groove is positioned at the middle part of concave punch upper end, and described concave punch is comprised of two sub-punch, and the faying face of two sub-punch is positioned at groove.
Further, described two sub-punch are for removably connecting.
Further, described two sub-punch connect by screw rod.
Further, described screw rod is three, and three screw rods are set in qually spaced on concave punch.
Further, also comprise rapid wear type U-shaped clamp, described rapid wear type U-shaped clamp links together two sub-punch, described rapid wear type U-shaped clamp be positioned at groove under, and rapid wear type U-shaped clamp is arranged on the outer surface of concave punch.
Further, on concave punch, also comprise reinforcement, reinforcement be arranged on screw rod under.
The beneficial effects of the utility model are: because concave punch of the present utility model is comprised of two sub-punch, therefore in process of production, when concave punch is subject to impact that two-sided lateral pressure and material flow into and produces the trend of spalling, concave punch can separate automatically, has avoided making because of spalling concave punch to scrap.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the new A-A cutaway view of this practicality;
Parts, position and numbering in figure: screw rod 1, groove 2, U-shaped card 3.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 and 2, concave punch of the present utility model comprises groove 2, and described groove 2 is positioned at the middle part of concave punch upper end, and described concave punch is comprised of two sub-punch, and the faying face of two sub-punch is positioned at groove 2.Owing to flowing into while affect when concave punch is subject to the two-sided lateral pressure of patrix and material in production process, the stress that groove 2 places are subject to is maximum, so at groove 2 places of concave punch, concave punch is divided into Split type structure.When concave punch produces the trend of spalling, concave punch can separate automatically from groove 2, has avoided making because of spalling concave punch to scrap.
Described two sub-punch are for removably connecting.In order to guarantee that Split type structure is combined into complete punch, two sub-punch need to be coupled together, for the ease of Split type structure is changed, be designed to removably connect.
Described two sub-punch connect by screw rod 1.Owing to having adopted screw rod 1 to connect, in process of production, the power of the connection of the screw rod 1 that Split type structure is linked together can be eliminated side force, has therefore effectively avoided the spalling of concave punch.
Described screw rod 1 is three, and three screw rods 1 are set in qually spaced on concave punch.During concrete enforcement, 1, three screw rod 1 of 8.8 grades of screw rods can firmly link together Split type structure, three screw rod 1 spaced sets can so that concave punch stressed evenly, avoid producing because of unbalance stress distortion.
Also comprise rapid wear type U-shaped card 3 plates, described rapid wear type U-shaped card 3 plates link together two sub-punch, described rapid wear type U-shaped card 3 plates be positioned at groove 2 under, and rapid wear type U-shaped card 3 plates are arranged on the outer surface of concave punch.Rapid wear type U-shaped card 3 plate rapid wear type U-shaped card 3 plates play the connection function of strengthening two sub-punch on the one hand, play on the other hand forewarning function.When mould is because side force and the material that bedding-in did not produce at that time flows into power, may be greater than the connection power of three screw rods 1, screw rod 1 fracture that will not ear a heavy burden, rapid wear type U-shaped card 3 plates that are at this moment arranged on the outer surface of concave punch also can rupture.When operating personnel find the 3 plate fracture of rapid wear type U-shaped card, just know that, in the inside of concave punch, screw rod 1 may rupture, at this moment operating personnel can take safeguard measure in time, prevent from producing crannied product.
On concave punch, also comprise reinforcement, reinforcement be arranged on screw rod 1 under.The reinforcement that is arranged on screw rod 1 below can further improve the intensity of concave punch self.
