Curtain rod metal piece stamping stepping die

Abstract

The invention discloses a curtain rod metal piece stamping stepping die and relates to the technical field of metal stamping. The curtain rod metal piece stamping stepping die comprises a machine station, a base and a stamping cylinder arranged on the machine station, an upper die holder arranged at the bottom of the stamping cylinder, an upper die component arranged at the bottom of the upper dieholder, and a lower die component arranged above the base, wherein a stamping passage is formed between the upper die component and the lower die component; a feeding mechanism is arranged on one side of the machine station and comprises a transferring table, a transferring roller set arranged on the transferring table, and a pushing component arranged on the side, close to the machine station, of the transferring roller set; the transferring roller set comprises vertical frames arranged on the two sides of the transferring table, an upper transferring roller and a lower transferring roller rotatably connected between the vertical frames, and a transmission motor coaxially connected at the end part of the upper transferring roller or the lower transferring roller; and a sheet metal transferring passage is formed between the upper transferring roller and the lower transferring roller and is as high as the stamping passage. The curtain rod metal piece stamping stepping die has the benefits of carrying out continuous stamping on the sheet metal longer than the lower die component, feeding without halt and being high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of metal stamping, in particular to a stepping die for stamping metal parts of curtain rods. Background technique [0002] Modern curtain rods require the use of a hook in the form of a figure 1 , in order to improve the production efficiency of the metal hook, a stepping die is used for continuous molding in production. Stepping die, also known as continuous die, refers to the cold stamping die that uses strip-shaped stamping raw materials in one stamping stroke, and uses several different stations on a pair of molds to complete multiple stamping processes at the same time. The stamping is completed once, and the material belt is moved once at a fixed distance until the product is completed. The utility model whose notification number is CN207479333U discloses a kind of bead forming automatic stepping mold, which includes an upper mold assembly and a lower mold assembly. The upper mold assembly includes u...

Problems solved by technology

[0004] However, the above-mentioned existing technical solutions have the following defects: the feeding of the stepping die is driven by the stepping rod, that is, the plate is first placed on the lower die assembly, and when the upper die assembly and the lower die assembly are completed once After stamping, the lower die assembly and the stepping rod are driven to a station through the stepping telescopic mechanism, and the workpiece is sent to the next station in turn, and the stepping rod is returned at the same time to complete a process

[0005] The above-mentioned existing technical solutions have the following defects: due to the limited size of the upper die assembly and the lower die assembly, the above-mentioned stepping die can only carry out continuous stamping on a sheet whose length is less than the length of the lower die. After the blank, it needs to stop and load again, which seriously affects the working efficiency of the equipment
