Description

Technical Field

[0001] This utility model relates to the field of mold steel plate processing, and more specifically, to a high-precision milling device for mold steel plates. Background Technology

[0002] In modern manufacturing, mold steel plates are key materials for manufacturing various industrial parts, product shells, and precision components. Their processing accuracy and surface quality directly affect the performance, service life, and appearance quality of the final product. With the advent of Industry 4.0 and the rapid development of industries such as automobiles, aerospace, electronics and communications, and medical devices, the processing requirements for mold steel plates are becoming increasingly stringent. In particular, in high-precision milling and grinding, traditional processes and equipment can no longer meet the market's demand for high efficiency, high precision, and high stability.

[0003] Traditional milling and grinding of mold steel plates mostly uses manual or semi-automatic machine tools. These machines have many limitations in the processing process, such as the processing accuracy being greatly affected by the operator's skill level, making it difficult to guarantee the uniformity of dimensional tolerances and shape accuracy, and the degree of automation is low. Although there are also CNC milling and grinding devices designed, during processing, it is usually necessary to clamp and fix the workpiece, i.e., the mold steel plate. However, the clamping structure itself partially covers the top of the mold steel plate to be milled, so the clamping position needs to be adjusted after processing before processing can continue, which affects the processing efficiency.

[0012] The beneficial effects of this utility model are:

[0013] 1. The present invention has a simple and reasonable structural design and is easy to operate. It is equipped with a drive mechanism and a movable processing table, and several electromagnets are embedded in the top of the movable processing table. In use, the mold steel plate is placed on the top of the movable processing table. Then, the electromagnets embedded in the top of the movable processing table are energized to generate magnetism and magnetically attract the mold steel plate with high iron content.

Then, the output end of the hydraulic cylinder is controlled to push the U-shaped frame to descend, so that the position of the milling cutter gradually descends to the required position and stops. Then, as needed, the first servo motor is started to drive the first screw to rotate, which in turn drives the movable seat to move in the horizontal longitudinal direction, thereby adjusting the position of the milling cutter in the horizontal longitudinal direction. This, together with the drive mechanism, drives the mold steel plate to move in the horizontal transverse direction, thereby achieving stable milling treatment on one side of the mold steel plate.
