Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that most of the existing technologies do not have the shock absorbing function, and the relatively large pressure generated during the punching process will cause certain damage to the mold itself and affect the service life of the mold. At the same time, the existing mold is used to It is easy to get stuck in the punching die hole, causing blockage and affecting the subsequent punching process. The surface temperature of the impacted waste is high, and it is easy to burn when it is directly collected. Operation method

Embodiment 1

[0037] refer to Figure 1-7 , a kind of curved surface punching die and its operation method, comprising box 1, punching machine 2, upper die 3, lower die 4, punching machine 2 is fixed on the inner wall of box body 1, and upper die 3 is fastened and connected on the punching machine 2, the lower mold 4 is located in the box body 1, the upper mold 3 matches the lower mold 4, the side wall of the box body 1 is provided with a material inlet and a material outlet, the lower end of the upper mold 3 is provided with a punch, and the lower mold 4 is provided with a blanking hole 505, the punch matches the blanking hole 505, and the bottom of the lower mold 4 is provided with multiple sets of first chute 6, and the first chute 6 is slidingly connected with a support rod 601, and the support rod 601 is located at One end in the first chute 6 is fixedly connected with a first spring 602, the end of the first spring 602 away from the support rod 601 is fixedly connected to the inner wa...

Embodiment 2

[0040] refer to Figure 1-7 , an arc surface punching die and its operating method are basically the same as in Embodiment 1, furthermore, a water tank 104 is provided in the box body 1, a sphere 102 is provided in the water tank 104, and an air inlet is provided on the sphere 102 The end of the air intake pipe away from the gas cylinder 10 is connected to the sphere 102, and the outside air enters the sphere 102 along the air inlet. The water tank 104 is filled with refrigerant liquid. 10 extracts the cold air in the sphere 102 through the intake pipe, which increases the cooling effect of the air cylinder 10 on the waste.

Embodiment 3

[0042] refer to Figure 1-7 , an arc surface punching die and its operating method are basically the same as in Embodiment 1, furthermore, a second chute 5 is provided in the blanking hole 505, and a limit rod 501 is slidably connected in the second chute 5 One end of the limit rod 501 located at the second chute 5 is fixedly connected with a second spring 502, and the end of the second spring 502 away from the limit rod 501 is fixedly connected with the inner wall of the second chute 5, when the punch is pressed into the blanking When the hole 505 is reached, the punching is completed, and the waste material falls into the blanking hole 505. Due to the high pressure between the punch and the raw material, there may be waste stuck on the lower surface of the punch. When the punch slides out of the blanking hole 505, The limit rod 501 is reset under the elastic force of the second spring 502, and the waste stuck on the bottom surface of the punch will be stuck under.

Abstract

The invention discloses a cambered surface punching die and an operation method thereof, and belongs to the field of punching mechanical equipment. The cambered surface punching die comprises a box body, a punching machine, an upper die and a lower die, the punching machine is fixed to the inner wall of the box body, the upper die is fixedly connected to the output end of the punching machine, the lower die is located in the box body, the upper die is matched with the lower die, and a feeding port and a discharging port are formed in the side wall of the box body; according to the punching device, through arrangement of the first sliding grooves, the first springs and the supporting rods, damping and buffering are conveniently conducted in the punching process, vibration and noise generated during impact are reduced, waste in a discharging hole is conveniently pushed and tamped through arrangement of a rotating rod, a supporting rod and a push rod, blockage caused by the fact that the waste is clamped in the discharging hole is prevented, through arrangement of a magnet block, the waste is conveniently adsorbed, and the punching efficiency is improved. And the waste materials and the magnet blocks can be separated conveniently through the arrangement of a material blocking groove, and the waste materials in the material collecting bin can be cooled conveniently through the arrangement of an impeller, a rotating shaft, a cam and an air cylinder.

Description

technical field [0001] The invention relates to the technical field of punching machinery and equipment, in particular to an arc surface punching die and an operation method thereof. Background technique [0002] Mold, as a kind of high-efficiency production tool, is an extremely widely used and important process equipment in industrial production.
