Abstract
The utility model relates to automobile die design manufacturing technology field, particularly relates to a kind of material pressing core with die case, for solving the defect producing burr in current die trimming punching production process because binder is insufficient.A kind of material pressing core with die case of the present utility model comprises material pressing core body, die case, described material pressing core body is provided with the installing hole run through, the bottom that described installing hole comprises top and is connected with described top, the shape on described top and the profile of described die case match; Described die case to be located in described top and to be fixedly connected with described material pressing core body with antirotation keys by screw.The beneficial effects of the utility model are: die manufacturing cycle is shortened, safety, are convenient to implement; Its pressure-plate-force is abundant, and can reduce the problem producing burr in die trimming punching production process because binder is insufficient, the cost of associated components band wedge angle or small round corner material pressing core cover plate reduces greatly because of standardization.
Description
Technical field
The utility model relates to automobile die design manufacturing technology field, particularly relates to a kind of material pressing core with die case.
Background technology
In Auto body panel die design manufacture process, when punching shape has wedge angle and small round corner, material pressing core via hole place cannot process and put in place.Have three kinds of solutions at present: 1) add cover plate, this scheme needs to process installed surface, screwed hole pin hole etc., and also need to purchase cover plate, cost is higher, sometimes also can affect intensity; 2) be processed into Rouno Cormer Pregrinding Wheel, pincers worker later stage hand finish puts in place, but this scheme pincers worker later stage hand finish, to the very large workload of pincers worker increase; 3) programming processes a roundlet with minimum cutter at sharp corner, but this scheme bight is without binder, and punching quality is bad, jagged.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of material pressing core with die case.
The technical solution of the utility model is: a kind of material pressing core with die case, comprise material pressing core body, die case, it is characterized in that: described material pressing core body is provided with the installing hole run through, the bottom that described installing hole comprises top and is connected with described top, the shape on described top and the profile of described die case match; Described die case to be located in described top and to be fixedly connected with described material pressing core body with antirotation keys by screw, and described screw and described antirotation keys are arranged in described bottom, are provided with lock washer between described screw and described antirotation keys; The inwall compact siro spinning technology on described die case and described top, described antirotation keys and described die case compact siro spinning technology, the bottom surface compact siro spinning technology of described antirotation keys and described bottom.
Described die case is non-quenching type die case.
The beneficial effects of the utility model are: die manufacturing cycle is shortened, safety, are convenient to implement; Its pressure-plate-force is abundant, and can reduce the problem producing burr in die trimming punching production process because binder is insufficient, the cost of associated components band wedge angle or small round corner material pressing core cover plate reduces greatly because of standardization.
Accompanying drawing explanation
Fig. 1 is the structural representation after the utility model embodiment is installed.
Fig. 2 is the assembling schematic diagram of the utility model embodiment.
Fig. 3 is the structural representation of installing hole in the utility model embodiment.
In figure, 1. non-quenching type die case, 2. screw, 3. antirotation keys, 4. lock washer, 5. material pressing core body, 6. installing hole, 61. tops, 62. bottoms.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is explained.
As shown in Figure 1, Figure 2 and Figure 3, a kind of material pressing core with die case of the present utility model comprises material pressing core body 5, non-quenching type die case 1, screw 2, antirotation keys 3, lock washer 4, installing hole 6.
Installing hole 6 is located on material pressing core body 5, runs through material pressing core body 5.
The bottom 62 that installing hole 6 comprises top 61 and is positioned at below top 61.Top 61 is connected with bottom 62.The inner wall shape on top 61 and the profile of non-quenching type die case 1 match.
Non-quenching type die case 1 is arranged in the top 61 of installing hole 6, and with the inwall compact siro spinning technology on top 61.
Antirotation keys 3 is arranged in bottom 62, and with non-quenching type die case 1 compact siro spinning technology, simultaneously also with the diapire compact siro spinning technology of bottom 62.Antirotation keys 3 rotates for preventing non-quenching type die case 1 and drops.
Screw 2 is installed in the screw of antirotation keys 3.
Lock washer 4 is installed between screw 2 and antirotation keys 3.Screw 2 and lock washer 4 are for fixing antirotation keys 3.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
