Problems solved by technology

[0003] The problem with the traditional ordinary grinding method is that the template processed under the action of magnetic force will still be deformed after processing and demagnetization. The thinner the template, the greater the deformation, which cannot meet the needs of high-precision molds.

Embodiment 1

[0022] A grinding method to ensure the flatness of high-precision mold templates. The grinding process of the template plane: (1) Put the template 2 on the electromagnetic chuck 3 of the grinder, rotate the magnetic button to make the electromagnetic disk in a magnetized state, and adjust the grinding wheel , rough grinding one side; (2) Install a baffle on one side of the electromagnetic chuck 3, and the template 2 is close to the baffle 4, and coarsely grind the other side; (3) Rotate the magnetic button to make the electromagnetic disk 3 in a demagnetized state, and finish dressing the grinding wheel 1 , the template 2 uses the residual magnetism and the baffle plate 4 to repeatedly finely grind both sides, so that the flatness of the template 2 reaches the requirement within 0.01mm.

[0023] Concrete structure and working process thereof of the present embodiment:

Abstract

The invention relates to a grinding method for ensuring the template planeness of a high-precision die, belonging to the technical field of ground finish. The grinding method for ensuring the template planeness of the high-precision die is characterized in that the process for grinding a template plane comprises the following steps: (1) putting a template on an electromagnetic chunk of a grinder, magnetizing, adjusting a grinding wheel, and roughly grinding one side of the template; (2) assembling a baffle on one side of the electromagnetic chuck, attaching the template to the baffle closely, and roughly grinding the other side of the electromagnetic chuck; and (3) demagnetizing the electromagnetic chuck, and finely grinding two sides of the template by utilizing residual magnesium and the baffle to achieve the requirement on the template planeness. The grinding method for ensuring the template planeness of the high-precision die has the advantages of simple process, high manufacture accuracy, high template planeness, high working efficiency, high die quality, long service life of a punch and the like.

Description

technical field [0001] The invention belongs to the technical field of grinding processing, in particular to a grinding method for ensuring the flatness of a high-precision mold template. Background technique [0002] At present, in precision stamping dies, the requirements for the flatness of the template are very strict, and poor flatness will directly affect the processing accuracy of the entire set of dies and the accuracy of the product. Such as image 3 shown. Generally, a grinder is used to ensure the flatness of the template. The basic steps of traditional grinding are: (1) Put the template 7 on the electromagnetic chuck 8 of the grinder, rotate the magnetic button to the magnetized state, adjust the grinding wheel 6, and rough grind Side A, just grind it out. (2) Turn over and clamp, roughly grind surface B, and leave a margin for fine grinding. (3) Finely trim the grinding wheel, and repeatedly finely grind both sides until it meets the requirements.
