Description

Technical Field

[0001] The present invention relates to the technical field of iron core punching, and in particular to a balanced iron core punching device. Background Art

[0002] The rice hulling rubber roller is a key component of the rice huller and a crucial piece of equipment for hulling rice. It comes in wheel, sleeve, and tuck styles. Its working principle is that two rubber rollers rotate at opposite speeds, forcing the rice grains between them to squeeze, rub, and peel them, thereby removing the hulls and converting them into rice. The rice hulling rubber roller consists of a hollow iron-core steel roller (with a central partition) and a rubber roller sleeved over it. The wheeled hulling rubber roller is positioned using the central partition hole of the iron-core steel roller. Three or four bolt holes are attached to the two main shafts of the rice huller, so holes must be drilled in the central partition plate of the iron-core steel roller.

[0003] For example, the patent document with publication number CN1289650A, publication date April 4, 2001, and titled "Production Process of Single-Support Rice Husking Rubber Roller Steel Plate Core", includes processes such as cutting and machining. The production process flow is as follows: cutting 2-5mm thick low- and medium-carbon steel plates into blanks; stretching the blanks into cylinders with bottoms; trimming off excess edges; machining a positioning hole in the center of the bottom of the cylinder; welding the outer bottom surfaces of the two cylinders together to form flanges; machining connecting holes on the plane of the flange to form the steel plate core; surface treating the core; and inspecting. The specific method for making the connecting holes is recorded in the manual as follows: punching out more than three connecting holes of 10.5-14mm on the plane of the flange with a punch press or drilling the connecting holes with a drill press to make the single-supported Bigu rubber roller steel plate core.

[0004] The shortcomings of the existing technology are that the partition plate in the middle of the rice hulling rubber roller is generally punched by stamping or drilling, and the existing equipment can only drill one hole at a time, which makes the efficiency low. At the same time, after long-term use of the existing equipment, the matching gap between the structures will be too large and wear and tear will occur, resulting in uneven drilling force and low drilling accuracy.

When the drill bit 524 is adjusted and the partition plate in the middle of the iron core is drilled, due to the fact that part of the position of the partition plate in the middle of the iron core may be uneven, a certain drill bit 524 drills the partition plate of the iron core, and other The drill bit 524 has not yet touched the partition plate of the iron core, or the drilling assembly 52 has worn out after long-term use, so that the force on each drill bit 524 is uneven. In order to solve the above-mentioned uneven force on the drill bit 524, the cylinder 51 drives the drill bit 524 to descend and touch the partition plate in the middle of the iron core. While the drill bit 524 drills the partition plate, the extended end of the cylinder 51 descends and squeezes each of the pressure plates 541, so that the pressure plates 541 The rectangular strip of 41 enters the strip groove 522 through the rectangular groove, so that the pressure plate 541 passes through the rectangular groove to squeeze the sliding part 5231, so that the sliding part 5231 drives the drill bit 524 to vertically descend in the gap between the strip groove 522 and the sliding part 5231, thereby ensuring that the force on each drill bit 524 remains consistent.
