[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0037] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] Reference Figure 1-4 As shown, a stamping and forming discharge device for a contact knife 6 has the feeding side on the left side of the device. It includes an upper mold assembly 1 and a lower mold assembly 2. Four external guide pillars 4 are provided between the upper mold assembly 1 and the lower mold assembly to guide the upper mold assembly when it moves up and down. The up and down movement of the upper mold assembly 1 is driven by an external hydraulic cylinder. The lower mold assembly 2 is provided from bottom to top with a lower mold base 23, a lower pad 22 and a lower template 21. The lower template 21 is provided with a first stamping station and a second stamping station. The upper mold assembly 1 is provided from top to bottom with an upper mold base 11, an upper clamping plate 13, a stop plate 14 and an upper ejector plate 15. Four internal guide pillars 16 are also provided between the stop plate 14 and the upper ejector plate 15.

[0039] The upper clamping plate 13 is provided with a first punch 131, a second punch group 132, a third punch group 133, a fourth punch 134, and a fifth punch 135 from left to right, and all of them pass through the stop plate 14 and the upper stripper plate 15. The lower template is provided with discharge holes corresponding to each punch. In order to facilitate the discharge of scrap material, a frame is also provided below the lower die assembly 2. The first punch 131 is used to punch a circular positioning hole 51 in the material plate 5. The circular positioning hole is located at the notch on the contact knife 6. This position needs to be reduced. The second punch group 132 initially punches out the side profile of the protrusion of the contact knife 6. Then the third punch group 133 is used to perform fine punching on the side profile of the protrusion of the contact knife 6 to make it meet the size requirements. The fourth punch 134 is used to punch out the notch on the contact knife 6. The fifth punch 135 is used to cut and separate the contact knife 6 after the end of the material plate 5 has been punched. The material plate 5 is fed step by step in the device so that the plate material passes through each punch in sequence.

[0040] A guide pin 151 is provided at the bottom of the upper stripper plate 15. The guide pin 151 is located between the second punch group 132 and the third punch group 133. When the upper stripper plate 15 moves downward, the guide pin 151 is inserted into the positioning hole 51 on the material plate 5 to play a positioning role, which can make the position of each punch more accurate and ensure the yield rate.

[0041] The lower template 21 is also provided with a straight-line ejection mechanism 3, which ejects the cut contact blade 6 perpendicular to the feeding direction.

[0042] Specifically, when the upper side edge of the protrusion of the contact knife 6 is required to be chamfered, the upper stripper plate 15 is provided with two chamfering inserts 152 on the side of the second stamping station away from the first stamping station, and the lower template 21 is also provided with two chamfering inserts 152. When the upper mold assembly 1 and the lower mold assembly 2 are closed, the four chamfering inserts 152 stamp the edges of the contact knife 6.

[0043] Specifically, the lower template 21 is also provided with a first floating block 24 that can slide up and down. The upper surface of the lower template 21 is also provided with first guide blocks 25 on both sides near the first floating block 24 to limit the position of the material plate 5 on both sides. The lower template 21 is also provided with two second floating blocks 26 that can slide up and down. The second floating blocks 26 are located to the right of the first floating blocks 24. The sides of the second floating blocks 26 have first grooves that slide with the sides of the material plate 5. Both the first floating blocks 24 and the second floating blocks 26 have springs at their bottoms to lift them upwards. This is to facilitate the feeding of the material plate 5 and reduce friction between the material plate 5 and the lower template 21, requiring it to be lifted from the surface of the lower template 21. When the upper mold assembly 1 presses down, it is then pressed back onto the surface of the lower template 21.

[0044] Furthermore, the material plate 5 can move up and down. The displacement of its sides is restricted near the feeding end, and it also needs to be restricted near the discharge end to ensure the accuracy of its cutting position. The lower template 21 is also provided with a first cutting die 28 and a second cutting die 27. The first cutting die 28 and the second cutting die 27 are combined to form a hole, which is the die hole used to discharge scrap material during cutting. The first cutting die 28 is provided with a second groove, which is exactly engaged with the side of the material plate 5. The second cutting die 27 is provided with two third grooves, which are exactly engaged with the protrusion of the contact knife 6. The material plate 5 is cut from the middle of the first cutting die 28 and the second cutting die 27, and both ends are limited.

[0045] Furthermore, when the cut contact 6 is placed inside the second cutting die 27, it needs to be lifted and pushed out for feeding. To achieve this step, the lower template 21 is provided with a third floating block 29 that can slide up and down on the right side of the second cutting die 27, and the bottom of the third floating block 29 is provided with a spring that can lift the contact 6. When the upper die assembly 1 is pressed down, it can be compressed downward. The linear ejection mechanism 3 includes a linear drive component 31, a push block 32, a first slide block 33, and a second slide block 34. The push block 32 is driven by the linear drive component 31 and slides in cooperation with the first slide block 33 to push the contact 6 from the third floating block 29 into the second slide block 34, and guides it for feeding through the second slide block 34.

[0046] The linear drive component 31 is preferably a cylinder, which has a simple structure, is relatively easy to maintain, and can achieve rapid linear motion.

[0047] Specifically, since the material plate 5 is relatively thick, in order to prevent the material from deforming and extending its length during the stamping process, the lower template 21 is also provided with a stop block 210 on the right side of the linear ejection mechanism 3.

[0048] Specifically, an upper pad 12 is provided between the upper die holder 11 and the upper clamping plate 13 to prevent the upper end face of each punch from directly contacting the upper die holder 11 and to improve the service life of the upper die holder 11.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
