Detailed Description

The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings.

As shown in fig. 1, the engineering mold corresponding to the rounding forming structure of the preferred embodiment of the present application includes an upper mold 1 and a lower mold 2, which are engaged with each other.

The upper die 1 includes an upper die base 101, an upper punch fixing plate 102 and an upper punch 103, the upper punch fixing plate 102 is disposed on one side of the upper die base 101, one end of the upper punch 103 is connected to the upper punch fixing plate 102, and the other end is provided with a cylindrical punching portion 103 a. The upper die base 101 is further provided with a material pressing plate 104 which is pressed against the upper punch 103. Specifically, as shown in fig. 2 and 3, in the present embodiment, an upper punch fixing plate 102 is provided at a rear middle position of the upper die holder 101, and an upper punch 103 is provided in the front-rear direction and one end thereof is fixed to the upper punch fixing plate 102. The pressure plate 104 is located at the front end of the upper punch fixing plate 102, and the pressure plate 104 is pressed against the upper punch 103 and provides a downward pressure thereto.

The lower die 2 comprises a lower die holder 201 and a lower forming die 202 fixed in the middle of the lower die holder 201, as shown in fig. 4, the lower forming die 202 comprises a forming portion 202a for forming a round and a matching surface 202b, and the forming portion 202a is provided with an arc matched with the punching portion 103 a.

In order to facilitate the rounding forming, the workpiece 3 needs to be bent and formed to a w shape as shown in fig. 5 in advance, and the workpiece 3 includes a forward arc surface 3a and a reverse arc surface 3b located between the forward arc surface 3a and the forward arc surface 3a, so that the reverse force of the material can be reduced, and the rounding forming is facilitated. In addition, the positive arc surface 3a cooperates with the mating surface 202b, and also functions to position the workpiece 3.

The working process of the engineering mould of the wrapping circle forming structure is as follows: firstly, the die is in a die opening state, a workpiece 3 is placed in the lower forming female die 202, and the positive arc surface 3a is attached to the matching surface 202b, so that the workpiece 3 can be positioned; then the upper die 1 is pressed downwards, the upper punch 103 moves downwards, and the punching part 103a of the upper punch is contacted with the reverse arc surface 3b of the workpiece 3; continuing pressing, matching the stamping part 103a with the forming part 202a, bending the reverse arc surface 3b downwards into an arc surface, and matching the arc surface with the positive arc surface 3a together to form a round-covered product 4 shown in fig. 6, wherein in the process, the forming height of the lower die needs to exceed half of a circle, so as to ensure the forming; after the round product 4 is formed, the die is opened, the round product 4 rises along with the upper punch, and when the round product 4 needs to be taken out, the round product only needs to be taken out from the front.

The utility model has the advantages that: 1. when the engineering mould is used for stripping materials, the product only needs to be drawn out from one end of the upper punch, so that the operation is convenient, the structure is simple, and the working efficiency is high;
