Description

Technical Field

[0001] The utility model relates to the field of metal profile molding, in particular to a die for cutting and pressing metal profiles. Background Art

[0002] Metal wire forming and cutting is one of the necessary processes in product processing in the logistics and warehousing industry, and is often used in the processing of components of turnover box products. Metal wire is a typical short-wire forming material. Its production process requires a lot of equipment and personnel. Due to its small material size, high processing accuracy requirements, and diverse shapes, there are great safety hazards in the profiling process. Such small workpieces with complex shapes need to be produced in a single step and multiple processes on the production line. In the traditional processing method, two sets of molds are required for cutting and profiling, and the original processing method is also divided into two steps, namely the first step: filament cutting; the second step: short wire forming, resulting in low overall processing efficiency. Therefore, it is urgent to design a processing mode that completes two processing steps with one mold. Utility Model Content

[0005] Preferably, there are six to eight groups of positioning bolts and springs under the floating lower module.

[0006] Specifically, the lower molding module is detachably mounted on the lower pad.

[0007] Specifically, the cutting knife is provided with a movable knife core.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] This mold realizes a one-station composite type with two process steps to complete the pressing of complex small parts, combining two processes into one, reducing labor and equipment costs, shortening processing time, significantly improving processing efficiency, and eliminating safety hazards in short-filament molding operations, thereby reducing labor intensity.

[0014] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0015] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0016] Example; see Figure 1-Figure 3A metal wire cutting and profiling die, comprising an upper die and a lower die arranged relatively to each other, and a feeding mechanism (not shown), wherein the upper die comprises an upper die plate, an upper pressure block 2 fixed on the upper die plate, and a forming upper die block 3, wherein a feeding slot block 10 is passed through the middle of the upper pressure block, and the feeding slot block 10 can be configured into different slot types according to different shapes of the cross section of the metal material 1; the lower die comprises a lower die plate, a lower pad, a floating lower pressure block 4 and a positioning baffle 7 installed on the lower pad by eight groups of springs and positioning bolts, and a blanking hole 8 passing through the lower die is also provided at a position corresponding to the forming upper die block 3 on the lower die plate, and a finished workpiece 9 is fed out from the bottom of the die through the blanking hole 8; a forming lower die block 6 is detachably installed on the rear side of the positioning baffle 7, and a lower cutting knife 5 and a knife groove thereof are fixed to the forming lower die block 6, a corresponding upper cutting edge 5' is provided on the upper pressure block 2, and the cutting tool is provided with a movable knife core, and the two cut the metal wire together.

[0017] During operation, the feeding mechanism pushes the front end of the metal wire to the position of the positioning baffle 7 through the feeding of the floating lower pressure block 4 to complete the positioning, and then the upper mold is pressed down. After the upper pressure block 2 presses the metal material 1, the metal material 1 continues to move downward, and the lower cutting knife 5 cuts off the metal material 1 from below. Then the upper mold continues to move downward, and the forming upper module 3 and the forming lower module 6 work together to stamp the metal material 1 into shape, producing a finished workpiece 9, and sending it out of the mold from the blanking hole 8, completing a complete profiling and cutting operation.
