The box that protects the conductor is called an incoming line box (or a starting box or a terminal box). The surface of the traditional steel welded incoming line box is sprayed or painted, which is easy to pollute the water environment and endanger human health. In addition, it has many production processes and a long production cycle. It needs to be processed in the factory and then transported to the installation site. The processed incoming line box is usually large in size, resulting in a large space and high cost for transportation. Therefore, in order to avoid the above technical problems, an assembled bus duct incoming line box is usually used in the actual production and transportation process. The spare parts of the incoming line box are prefabricated in the factory and packaged and transported to the site for assembly.

During processing, both ends of the angle aluminum profiles are sawed into 45-degree triangles so that two adjacent angle aluminum profiles can be connected at right angles at the corners of the incoming line box. Currently, the processing of angle aluminum profiles requires pre-marking of dimensions and punching with a punch press. The processing process is complicated, the production efficiency is low, and the degree of standardization is not high. Utility Model Content

[0051] Furthermore, the lower die base 2 is a rectangular plate structure, which is located directly below the upper die base 1. At least two guide pillars 21 are provided on the lower die base 2; the guide pillars 21 are perpendicular to the upper surface of the lower die base 2; a guide sleeve 22 adapted to the guide pillars 21 is provided at a corresponding position on the lower surface of the upper die base 1, and the guide pillars 21 are inserted into the guide sleeves 22, so that the upper die base 1 can slide relative to the lower die base 2 along the direction of the guide pillars 21; the guide pillars 21 and the guide sleeves 22 are designed to accurately guide and position the mold, and the upper die base 1 is guided by the guide pillars 21 to move along a predetermined path during the stamping process to maintain the consistency of the stamping profile each time, and the high processing accuracy and quality of the mold are guaranteed.

[0052] See also Figure 3Furthermore, the punch assembly 3 is located below the upper die base 1, and a pad 12 is provided between the punch assembly 3 and the upper die base 1, and the pad 12 is used to withstand the blanking force generated by the punch assembly 3 during stamping to prevent the upper die base 1 from being dented or deformed; the punch assembly 3 includes: a first punch 31, a second punch 32, a buffer pad 33 and a pressing plate 34; wherein the first punch 31 is a triangular prism structure, which is fixed to the middle part of the lower surface of the pad 12; during the stamping process, the first punch 31 moves with the upper die base 1, and the bottom edge of the first punch 31 is the punch blade, which contacts the die 4, and the right angle of the angle aluminum is sawed into a bevel.

[0053] As an embodiment of the present application, the cross-section of the first punch 31 is an isosceles triangle, and its base angle is 45°; using this technical solution, the two beveled edges of the bottom surface of the triangular prism of the first punch 31 can be used to saw the angle aluminum respectively, so that the mold can process two angle aluminums at the same time during one stamping process, thereby improving production efficiency; and the inclination angle of the beveled edge of the processed angle aluminum is 45°; after the beveled edges of two adjacent angle aluminums are spliced ​​together, they form a 90° corner of the incoming line box.

[0058] As a preferred embodiment of the present application, a positioning block 41 is further provided on the upper surface of the lower die base 2, and the positioning block 41 is located on one side of the die 4 and close to the die cutting edge; the length of the positioning block 41 matches the length of the die 4, so that after the angle aluminum is placed on the surface of the die 4, the end of the angle aluminum can abut against the positioning block 41; the design of the positioning block 41 plays a role in assisting the rapid positioning of the angle aluminum, and the end of the angle aluminum is pressed against the positioning block 41, that is, the angle aluminum can be aligned, allowing the punch assembly 3 to be stamped at the same position of different angle aluminums. This technical solution not only improves the processing efficiency, but also ensures the accuracy of stamping and sawing of each angle aluminum, thereby improving the standardization of the angle aluminum processing process.

[0059] See also Figure 1 and Figure 6 Furthermore, the clamping assembly 5 is located on the side of the die 4, and is used to press the angle aluminum against the surface of the die 4; the clamping assembly 5 includes, from close to the die 4 to away from the die 4, a guide bracket 51, a push rod 52, a movable pressing block 53 and an eccentric wheel 54;

[0060] The guide bracket 51 is in a rectangular block shape, fixed on the lower die base 2 and located on the side of the die 4, and a gap for accommodating the angle aluminum is formed between the guide bracket 51 and the die 4; guide holes (not shown in the figure) matching the number and diameter of the ejector rods 52 are horizontally arranged on the guide bracket 51, and the guide holes are used to limit the moving track of the ejector rods 52 so that the ejector rods 52 move in the horizontal direction;

[0061] The movable pressing block 53 is located above the lower die base 2 and can slide relative to the lower die base 2; one end of the push rod 52 is fixed on the movable pressing block 53 and the other end is inserted into the guide hole of the guide bracket 51; before stamping, the free end of the push rod 52 can be pressed against the angle aluminum by sliding the movable pressing block 53, so as to further prevent the angle aluminum from vibrating and moving, which affects the final processing accuracy;

[0062] The eccentric wheel 54 is rotatably connected to the top of the lower die base 2 through a rotating shaft. The circular surface of the eccentric wheel 54 is parallel to the upper surface of the lower die base 2. A handle is installed on the side of the eccentric wheel 54 to facilitate the operator to hold the eccentric wheel 54. The eccentric wheel 54 is in contact with the side of the movable pressure block 53 away from the push rod 52. Before stamping, the operator can rotate the eccentric wheel 54 by pushing and pulling the handle, and then move the movable pressure block 53 to make the push rod 52 lock the angle aluminum. It can be understood that both sides of the die 4 are provided with clamping assemblies 5, which can lock the two angle aluminums on the die 4. The clamping method of the eccentric wheel 54 in the above technical solution is based on torque. During the clamping process, the uniform distribution of the clamping force can be achieved, and the damage of the angle aluminum caused by excessive clamping can be avoided; the whole set of clamping assemblies 5 have the advantages of fast clamping action and good stability.

[0063] In the above technical solution, a return spring 55 is sleeved on the surface of the push rod 52; the return spring 55 is located between the guide bracket 51 and the movable pressure block 53; after the stamping is completed, the eccentric wheel 54 is loosened, and the return spring 55 can push the movable pressure block 53 away, so that the push rod 52 is away from the angle aluminum, making it convenient for the operator to take out the processed angle aluminum.

[0064] The angle aluminum beveling die provided in the present application locks and fixes the angle aluminum to be processed by means of a clamping component 5, and then cooperates with a punch component 3 and a die 4, so that two angle aluminums can be sawed at the same time in each stamping, thereby improving the processing efficiency of the angle aluminum; and after each group of angle aluminums completes the first stamping, the positions can be immediately exchanged with each other to complete rapid positioning and perform a second stamping on the other unprocessed side, thereby realizing batch, modular, and standardized production of angle aluminums.
