Description

Technical Field

[0001] The utility model relates to the technical field of punch rod processing equipment, in particular to a high-precision grinding device for a punch rod. Background Art

[0002] Punches are mold accessories made of steel materials suitable for molds such as high-speed steel, powder high-speed steel, and tungsten steel. They are suitable for cold heading, cold extrusion, stamping, hydraulics, injection molding and other processing industries. Punches need to be ground during production and processing to ensure the accuracy of the punches and the working effect of the punches when they are actually working. The current grinding device generally uses a grinding disc for grinding. Grinding with a grinding disc can only be used to grind a smaller range or area of ​​the punch, and cannot be used for full-surface grinding. The grinding efficiency is low, time is wasted, and the time and labor costs are high. There are certain defects and shortcomings, so it needs to be improved. Utility Model Content

[0024] It should be noted that by fixing the track plate 8 on the workbench 1, the setting of the track plate 8 can realize the sliding limiting function of the lifting assembly 5, and the grinding assembly 4 is fixed on the lifting assembly 5 to realize the stable lifting and lowering of the grinding assembly 4. When the grinding assembly 4 is lifted and lowered, it can continuously grind the punch rod body 3 to remove burrs, etc. The grinding assembly 4 includes an arc-shaped grinding sheet 401 and a base plate 403. Among them, the base plate 403 is used for the installation of the arc-shaped grinding sheet 401. One side of the arc-shaped grinding sheet 401 is an arc-shaped surface, and the arc-shaped surface is adapted to the contour of the punch rod body 3, so that when the arc-shaped grinding sheet 401 moves, it can perform a large-area grinding process on the punch rod body 3, and perform surface-to-surface contact grinding of the punch rod body 3. This method can quickly grind the punch rod body 3 and reduce time costs.

[0025] like Figure 1 and Figure 2As shown, in some embodiments, the lifting assembly 5 includes a sliding block 501 slidably connected to the track groove on one side of the track plate 8, and a round rod 502 fixed on one side of the sliding block 501, and a fixed seat 503 is welded to the end of the round rod 502 away from the sliding block 501, and the base plate 403 is fixedly connected to the fixed seat 503 by means of a screw 402.

By fixing a synchronous wheel 10 at the lower end of the bidirectional screw 6 and the lower end of the drive shaft 9, and a synchronous belt 11 is provided between the two synchronous wheels 10, when one of the synchronous wheels 10 rotates, the other synchronous wheel 10 will also rotate, thereby causing the bidirectional screw 6 and the chuck 2 to rotate at the same time. By installing a motor 12 on a mounting seat 13 on the lower surface of the workbench 1, the motor 12 can drive the synchronous wheel 10 to rotate. This method can realize the simultaneous rotation of the bidirectional screw 6, the chuck 2, and the punch rod body 3. When the bidirectional screw 6 rotates, the grinding assembly 4 moves back and forth, and each surface of the punch rod body 3 is continuously ground.
