Problems solved by technology

The hydraulic press is large in size and expensive in equipment, and the oil spilled after long-term use is easy to dirty the production workshop
In addition, using a hydraulic punch to punch or press some thin sheet metal parts, pipe fittings or plastic parts will increase the production cost of the parts
[0003] There are also some small desktop electric punching machines, but most of them have complicated mechanisms, high failure rates, and are very inconvenient to use.

Embodiment Construction

[0010] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 Shown, a kind of punching machine comprises frame 1, and frame 1 is provided with mount 2, and mount 2 is movable to be provided with rotating arm 3, is hinged with cylinder 4 on frame 1, and the piston head of cylinder 4 is connected with One end of the rotating arm 3 is hinged together, and the other end of the rotating arm 3 is movably provided with a punch seat 5, the punch seat 5 is provided with a punch 6, the frame 1 is provided with a lower die seat 7, and on the lower die seat 7 A lower die 8 is provided. A plurality of guide rods 9 are arranged on the lower mold base 7 , and the ends of the guide rods 9 pass through the punch base 5 .

[0012] Because the rotating arm 3 is set to drive the punch 6, the power arm is increased, so that the cylinder 4 only needs to apply a small thrust to obtain a large punchin...

Abstract

The invention discloses a hole puncher, which comprises a framework. A mount is arranged on the framework and movably provided with a rotary arm, the framework is hinged with an air cylinder, a piston head of the air cylinder is hinged with one end of the rotary arm, the other end of the rotary arm is movably provided with a punch holder, a punch is arranged on the punch holder, a lower die holder is arranged on the framework, and a lower die is arranged on the lower die holder. A plurality of guide rods are arranged on the lower die holder, and ends of the guide rods penetrate through the punch holder. The hole puncher is compact in structure, convenient to use and low-cost in production.

Description

technical field [0001] The invention relates to a punching machine. Background technique [0002] Usually during machining, if holes or grooves need to be punched on the sheet or pipe, it is performed on a hydraulic punch. The hydraulic press is bulky, expensive equipment, and the oil spilled after long-term use is easy to contaminate the production workshop. In addition, using a hydraulic punch to punch or press some thin sheet metal parts, pipe fittings or plastic parts will increase the production cost of the parts. [0003] There are also some small desktop electric punching machines, but most of them have complicated mechanisms, high failure rates, and are very inconvenient to use. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a punching machine with compact structure, convenient use and low production cost. [0005] In order to solve the above technical problems, the technical solution adopted in the p...
