A sheet metal isometric punching device based on the principle of ratchet movement

Abstract

The invention relates to the technical field of mechanical equipment, and discloses a sheet metal isometric punching device based on the principle of ratchet movement, including a frame, the inside of the frame is fixedly connected with a workbench, and the top of the workbench is fixed A fixed block is connected, the inside of the frame is slidably connected with a slider, the bottom of the slider is fixedly connected with a lifting rod, the bottom of the lifting rod is fixedly connected with a punching motor, and the bottom of the punching motor is movable A drill bit is connected, and a ratchet bar is fixedly connected to the top of the slider, and the top of the ratchet bar is movably connected with a limit pawl block, and the ratchet bar, the limit pawl block, the adjustment pawl block, and the connecting rod , the limit ring and the movable pin are used together to achieve the effect of driving the ratchet bar to slide to the right at an equal distance, so as to ensure that the drill bit moves to the right at the same distance and the hole spacing of the drilling holes is equal, thereby improving product quality. Avoid the trouble of pre-measurement punctuation, effectively improve the production efficiency of sheet metal punching.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a sheet metal isometric punching device based on the principle of ratchet movement. Background technique [0002] Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. It has been widely used in electronic appliances, communications, automobile industry, medical equipment and other fields. With the The application of sheet metal is becoming more and more extensive, and the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers must master the design skills of sheet metal parts proficiently, so that the designed sheet metal can meet the functions and Appearance and other requirements can also make the stamping die manufacturing simple and low cost. [0003] Among them, in the ...

Problems solved by technology

[0003] Among them, in the process of sheet metal processing, it is often necessary to perform equidistant drilling on sheet metal. However, the existing equidistant drilling requires pre-punched punctuation, and then punches through the punctuation to ensure that the hole spacing is equal. However, this punching method is complicated to operate, low in work efficiency, and the punching accuracy of this punching method is low, and the distance error between the holes is larger, especially when the number of holes is large, the error between the hole distances is even greater. thereby affecting product quality
