[0023] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The embodiment of the utility model provides a simple collar hole mold, which is provided with a bottom plate 4, the bottom plate 4 is placed on the top of two cushion blocks 3, and the cushion blocks 3 are placed at both ends of the bottom plate 4;

[0025] Among them, a punch 5 is provided above the base plate 4, and the punch 5 is connected to the base plate 4 through a hexagon socket head screw 1; a die 6 is provided above the punch 5, and the die 6 is arranged opposite to the punch 5; a spring 7 is also provided on the base plate 4, and the spring 7 is welded to the base plate 4.

[0027] Specifically, the spring 7 is used to assist in supporting the tube shell material 2 so that the tube shell material 2 remains horizontal; at the same time, the spring 7 needs to be designed with sufficient compression to ensure that after lifting, the height of the flanges on both sides of the product are controlled to be consistent.

[0028] Among them, choosing a spring 7 of appropriate size is very important for the feasibility of the tooling. After the specification verification of the spring 7 is completed, the spring 7 can be spot welded to the base plate 4.

[0029] In this embodiment, the punch 5 is further provided with a first step 8, a second step 9, and a third step 10; the first step 8, the second step 9, and the third step 10 are all provided with rounded transitions.

[0030] Specifically, the tube shell material 2 is positioned by the first step 8, and the first step 8 is also used to guide the die 6 to ensure the accuracy of the movement of the die 6. The second step 9 is used to support the tube shell material 2 to be lifted and turned up; the third step 10 is used to support the tube shell material 2, and the third step 10 also limits the tube shell material 2 after lifting.

[0031] In this embodiment, the die 6 is provided with a first stepped hole 11 and a second stepped hole 12, both of which are provided with rounded corners, and the rounded corner size matches the rounded corner size of the punch 5. The first stepped hole 11 is provided in conjunction with the first step 8 to guide the positioning of the die 6; the second stepped hole 12 serves to control the outer diameter of the collar hole and the height of the flange.

[0032] like Figure 3 As shown, during use, two cushion blocks 3 are placed on the equipment platform, with the spacing slightly larger than the length of the perforated tube shell material 2. Use the hexagon socket head screw 1 to connect the punch 5 and the bottom plate 4 together to form a combination. First, determine the collar hole position on the tube shell material 2, and make the blanking hole in advance. The size and shape of the blanking hole need to be calculated according to the product shape. The tube shell material 2 is inserted into the punch 5 of the combination, so that one end of the tube shell material 2 is pressed on the spring 7, and the other end is embedded in the punch 5. Start the equipment, press the upper panel of the equipment down until it contacts the die 6, and the equipment continues to move down. The die 6 moves down, and after contacting the tube shell material 2, the spring 7 is compressed. The tube shell material 2 is flanging and lifting under the joint action of the punch 5 and the die 6 to form the required lifting hole shape.

The punch 5 is also provided with a first step 8, a second step 9, and a third step 10; the first step 8, the second step 9 and the third step 10 are all provided with rounded transitions. The first step 8 is used to position the tube shell material 2 and guide the die 6; the second step 9 is used to support the tube shell material 2 to lift and flip up; the third step 10 is used to support the tube shell material 2, and the third step 10 also limits the tube shell material 2 after lifting. The die 6 is provided with a first stepped hole 11 and a second stepped hole 12, and both the first stepped hole 11 and the second stepped hole 12 are provided with a rounded transition, and the rounded corner size matches the rounded corner size of the punch 5. The first stepped hole 11 is provided in conjunction with the first step 8 to guide the positioning of the die 6; the second stepped hole 12 is used to control the outer diameter of the collar hole and the height of the flanging.
