[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the progressive die material strip pressing mechanism designed in the utility model comprises a lower die base 1, on which a material strip conveying channel 1.1 is reserved, and a material pressing groove 1.2 is provided on the upper surface of the lower die base 1 along one side of the material strip conveying channel 1.1; a material pressing plate 2 is provided in the material pressing groove 1.2 and extends horizontally toward the material strip conveying channel 1.1; the material pressing plate 2 can slide along the material pressing groove 1.2 to cover or move out the side edge of the material strip in the material strip conveying channel 1.1.

[0024] It should be noted that a plurality of pressing grooves 1.2 are continuously arranged along the conveying direction of the material belt conveying channel 1.1, and each group of pressing grooves 1.2 is correspondingly configured with a pressing plate 2 to meet the limiting function of the entire material belt.

[0025] In this embodiment, during normal stamping, the material strip can be conveyed step by step along the material strip conveying channel 1.1. Under the restriction of the pressing plate 2, the material strip can be prevented from deviating from the material strip conveying channel 1.1. When a sudden failure occurs and the mold needs to be repaired, the pressing plate 2 can be slid along the pressing groove 1.2 to contact the restriction on the material strip, so that the material strip can be quickly taken out, thereby improving the maintenance efficiency.

[0026] As an embodiment, the plate surface of the press plate 2 is provided with a guide slot 2.1 and a positioning pin hole 2.2 arranged along the sliding direction of the press plate 2 in sequence; the press plate 1.2 is also provided with a guide column 3 that is slidably matched with the guide slot 2.1, and a positioning pin 4 that is matched with the positioning pin hole 2.2 in sequence. The guide column 3 cooperates with the guide slot 2.1 to limit the sliding direction of the press plate 2, and the positioning pin hole 2.2 is locked or separated by the positioning pin 4 to achieve the fixing and movement of the press plate 2.

[0027] In this embodiment, two groups of guide long grooves 2.1 and positioning pin holes 2.2 are respectively provided to accurately limit the movable direction of the pressing plate 2 to ensure accuracy.

[0028] As an embodiment, the bottom wall of the material pressing groove 1.2 is also provided with a positioning pin receiving hole 1.3, and the positioning pin receiving hole 1.3 is provided with an elastic support member 5 for elastically supporting the positioning pin 4. When the material pressing plate 2 needs to be removed, the positioning pin 4 can be pressed so that the positioning pin 4 is completely received in the positioning pin receiving hole 1.3, and the material pressing plate 2 can be freely pushed at this time; after the inspection is completed, the material pressing plate 2 is pushed back to the original position, and under the elastic support of the elastic support member 5, the positioning pin 4 can be driven to lock the material pressing plate 2.

[0029] Specifically, the guide column 3 includes an upper limit section 3.1 and a lower guide section 3.2. The diameter of the upper limit section 3.1 is larger than the width of the guide long groove 2.1. Under the action of the upper limit section 3.1, the pressing plate 2 can be restricted from moving upward.

[0030] In addition, the distance between the upper limit section 3.1 and the pressing groove 1.2 is greater than the thickness of the pressing plate 2, ensuring that there is a certain gap between the pressing plate 2 and the material belt after assembly, thereby reducing the wear on the material belt during transportation.

[0031] As an embodiment, the diameter of the positioning pin receiving hole 1.3 is larger than the diameter of the positioning pin hole 2.2; the positioning pin 4 includes an upper pin head 4.1 and a lower pin seat 4.2 which match the positioning pin hole 2.2 and the positioning pin receiving hole 1.3 respectively.

[0032] Specifically, the elastic support member 5 is a spring, and a fixing groove 4.3 matching the spring is axially opened at the bottom end of the positioning pin 4. With the support of the spring, the upper pin head 4.1 can be pushed to lock the positioning pin hole 2.2, and at the same time, the lower pin seat 4.2 lifts the entire pressing plate 2, so that there is always a gap between the pressing plate 2 and the material belt to reduce wear.

[0033] As an embodiment, a replaceable wear-resistant plate 6 is installed at the bottom of the pressing plate 2, and the guide long groove 2.1 and the positioning pin hole 2.2 correspond to and penetrate the wear-resistant plate 6. The wear-resistant plate 6 can be made of a material with high hardness, high wear resistance and other characteristics, such as tungsten carbide, high-speed steel, manganese steel, chrome steel, chrome-manganese steel, chrome-nickel steel, silicon steel, etc.

[0034] As an embodiment, the pressing plate 2 is formed with tape guiding slopes 1.4 on both sides of the tape conveying channel 1.1, and the tape guiding slopes 1.4 can guide the tape in the tape conveying channel 1.1 to avoid obvious scratches caused by hard contact.
