Description

Technical Field

[0001] The utility model relates to the technical field of hardware punching, in particular to a punching die for side holes of a protective cover. Background Art

[0002] Pneumatic component protective covers effectively isolate the external environment and prevent dust, mud, water and other substances from entering the machine, thereby keeping the machine in good condition. If these substances enter the machine, it will reduce the operating efficiency and shorten the service life of the machine. In addition, the protective cover can also protect the hydraulic pump, pneumatic components and pipelines to ensure the normal operation of the machine.

[0003] Currently, the gas generator protective cover is a cap structure with multiple side holes distributed on its side walls. The punches of most stamping dies generally move along the opening and closing direction of the stamping die. Therefore, the punches can only punch holes on the top or bottom of the protective cover. However, it is difficult to complete efficient stamping processing of the workpiece if punching is performed on the opposite side walls of the protective cover. Utility Model Content

[0004] The utility model provides a protective cover side hole punching die to solve the problems in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a protective cover side hole punching die, comprising a lower die and an upper die, wherein the lower die is inlaid with guide pillars around it, and the upper die is inlaid with guide sleeves around it, and the lower die is clamped by the guide sleeves and guide pillars;

[0006] The lower die includes a bottom die plate, a lower fixed plate, a positioning core seat, a punch seat, a return spring and a punch. The lower fixed plate is mounted on the bottom die plate by bolts. The positioning core seat is embedded in the middle of the lower fixed plate, and a punching edge is provided around the positioning core seat. The punch seat is slidably connected to the four sides of the lower fixed plate and is elastically connected to the lower fixed plate by a return spring. A sliding slope is provided on the upper part of the punch seat. The punch is embedded in the punch seat, and the position of the punch corresponds to the punching edge.

[0007] The upper mold includes a top mold plate, a mold handle, an upper fixed plate and an inclined wedge. The mold handle is installed on the top of the top mold plate by bolts, and the upper fixed plate is installed on the bottom of the top mold plate by bolts. The inclined wedge is embedded around the upper fixed plate, and its inclined portion is close to the sliding slope of the punch seat.

[0008] Furthermore, a chip removal groove is provided in the middle of the positioning core seat, and punching edges are located at the upper and lower ends of the positioning core seat.

[0009] Furthermore, a chip cleaning port is provided in the middle of the bottom template, and the chip cleaning port corresponds to the position of the chip removal slot.

[0010] Furthermore, T-shaped slots are provided around the bottom template, and a T-shaped slider is provided at the bottom of the punch seat, which slides on the bottom template through the T-shaped slider and the T-shaped slots.

[0011] Furthermore, a sleeve hole is provided in the T-shaped slider, and the reset spring is installed in the sleeve hole.

[0012] Furthermore, the punch is located at the upper and lower ends of the punch seat, and the size of the punch is adapted to the punching edge.

[0013] Compared with the existing technology, the utility model provides a protective cover side hole punching die, which has the following beneficial effects:

[0014] The side hole stamping die of the protective cover places the workpiece upside down on the positioning core seat. During stamping, the upper die drives the inclined wedge downward, and the inclined surface of the inclined wedge contacts the push slope of the punch seat, so that the reset spring is compressed when the punch seat moves rapidly laterally. The punch seat drives the punch to rush to the side wall of the workpiece to complete the punching process. When the upper die rises, the reset spring expands to drive the punch seat to reset and separate the punch from the workpiece. Four side holes can be punched at one time, with the characteristics of high precision and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
