Figure 1 As shown, a material guide channel 1-1 is arranged in the middle of the back plate of the feeding structure 1, and a material guide plate is used to guide the material belt in the material guide channel 1-1 in the horizontal direction. The material guide plate includes: a first material guide plate 2 and a second material guide plate 3, and the first material guide plate 2 and the second material guide plate 3 are located on both sides of the material guide channel 1-1.

[0003] However, due to the manufacturing process and other reasons, the guide plate has a single-side clearance of 0.05mm at the die end, while the width tolerance of the stamping material strip is 0-0.02mm. This results in horizontal swinging of the actual stamping material strip during the feeding process. This swing during the feeding process will cause dimensional instability in the stamping process, which in turn leads to a decrease in the yield of products with high stamping requirements.

[0020] like Figure 2~Figure 3 As shown, the utility model includes a feeding device for stamping and forming a new energy vehicle connector terminal mold, which includes: a material guide channel 1-1, a back plate 1-2, a first material guide plate 2, a second material guide plate 3 and a side pressure structure 4.

[0021] The first material guide plate 2 and the second material guide plate 3 are fixed to the same side of the back plate 1-2, the material guide channel 1-1 is arranged in the middle of the back plate 1-2, and the first material guide plate 2 and the second material guide plate 3 are arranged on both sides of the material guide channel 1-1. Figure 3 As shown, the cross-section of the material guide channel 1-1 between the first material guide plate 2 and the second material guide plate 3 is convex-shaped, and the end adjacent to the back plate 1-2 is wider. The convex-shaped inner cavity can prevent the stamping material 5 from accidentally jumping out of the material guide channel 1-1 during its movement in the material guide channel 1-1.

[0022] The side pressure structure 4 includes: a side pressure guide groove 2-1, a mounting head 4-1, a pressing spring 4-2 and a side pressure block 4-4.

[0023] The side pressure guide groove 2-1 is formed on the first material guide plate 2 and is located between the first material guide plate 2 and the back plate 1-2; the side pressure guide groove 2-1 is perpendicular to the feeding direction and is connected to the material guide channel 1-1.

[0024] An internal thread is arranged on the inner cavity side wall of the side pressure guide groove 2-1 at one end away from the material guide channel 1-1; an external thread meshing with the inner thread of the installation cavity is arranged on the outside of the installation head 4-1, and the installation head 4-1 is installed in the inner cavity of the side pressure guide groove 2-1 based on the threaded connection; the side pressure material block 4-4 is movably installed in the inner cavity of the side pressure guide groove 2-1 connected to the material guide channel 1-1; the clamping spring 4-2 is arranged in the inner cavity of the side pressure guide groove 2-1 between the installation head 4-1 and the material guide channel 1-1, and the two ends are respectively connected to the installation head 4-1 and the side pressure material block 4-4. During the feeding process of the stamping material 5, the side pressure material block 4-4 presses one side of the stamping material 5 in the material guide channel 1-1 through the clamping force provided by the clamping spring 4-2, and presses the other side of the stamping material 5 against the side wall 3-1 of the second material guide plate 3, ensuring the stable movement of the material belt and effectively reducing the probability of horizontal swing of the material belt during the movement.

[0025] In specific implementation, a guide column 4-3 can also be set on the installation head 4-1, and the guide column 4-3 is fixedly connected to the installation head 4-1, and the length of the guide column 4-3 is controlled to ensure that there is enough space between the guide column 4-3 and the side pressure block 4-4 to move; the clamping spring 4-2 is mounted on the outer periphery of the guide column 4-3, and is arranged in the inner cavity of the side pressure guide groove 2-1 between the installation head 4-1 and the side pressure block 4-4, and the two ends of the spring are connected to the installation head 4-1 and the side pressure block 4-4.

[0026] In actual production work, the width tolerance of the material strip of the stamping material is 0-0.02mm, and the single-side gap between the material strip of the stamping material and the material guide plate at the die end is 0.05mm, and the clamping spring 4-2 is realized based on a rigid and strong spring; when there is no stamping material in the material guide channel 1-1, most of the structure of the side pressure material block 4-4 is in the inner cavity of the side pressure guide groove 2-1, and the specific length of the part exposed in the material guide channel 1-1 can be obtained through experiments. At the same time, the position adjustment of the mounting head 4-1 in the inner cavity of the side pressure guide groove 2-1 based on the threaded connection is realized to adjust the clamping force of the clamping spring 4-2.

[0027] like Figure 4 As shown, a guide chamfer 4-41 is provided on the rectangular side pressure block 4-4 in the direction of material travel to prevent the stamping material 5 from being damaged by the edges of the side pressure block 4-4 during travel. At the same time, when the head of the stamping material 5 presses against the side wall of the side pressure block 4-4, the side pressure block 4-4 can be smoothly pressed into the side pressure guide groove 2-1 along the guide chamfer 4-41, thereby ensuring that the material strip of the stamping material can smoothly travel in the material guide channel 1-1.

[0028] The number of the lateral pressure structures 4 is greater than 1 and they are evenly arranged along the feeding direction, ensuring that the stamping material 5 is evenly pressed in the traveling direction, further improving the positioning accuracy of the stamping material during the feeding process.

[0029] The inner cavity entrance of the material guide channel 1-1 on the side adjacent to the back plate 1-2 is in an eight-shaped shape, and the width of the material entrance 1-3 is greater than the width of other parts. Based on the eight-shaped entrance, it plays a guiding role when the material strip of the stamping material 5 enters the material guide channel 1-1.
