Embodiment Construction

[0010] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0011] The diamond wire drawing die production process of the present invention comprises: 1) selection of diamonds: selecting natural diamonds of good quality, with a weight of about 3-4 points. 2) Grinding: Grinding the selected natural diamond into two parallel planes on a grinding machine, the thickness of which is greater than or equal to 0.65mm. 3) Inserting sleeve: Insert the ground natural diamond 2 into the stainless steel mold sleeve 4 with metal powder 3, and then cover the cover sheet 1, such as figure 1 shown. Sintering in the hot-press sintering machine, so that the natural diamond 2 is fixed in the stainless steel mold cover 4 to obtain a rough mold cover. After sintering, the position of the natural diamond 2 in the stainless steel mold cover 4 and the hardness of the sintered body 6 must meet the specified technical requirements. 4) ...

Abstract

The invention discloses a diamond wire drawing die producing technique, including: 1) select diamond: selecting good-quality diamond; 2) grinding diamond: grinding the diamond out of surfaces; 3) insert in a case: inserting the well-ground diamond in a stainless steel die case added with metallic powder, then covering a covering plate and sending in heat-press sintering machine for sintering and obtaining a crude die case; 4) process the die case:; 5) punch by laser; 6) mould. It better saves the diamond, and largely reduces production cost, completely suitable for producing diamond wire drawing dies.

Description

technical field [0001] The invention relates to a production process of a wire drawing die, in particular to a production process of a diamond wire drawing die. Background technique [0002] The traditional diamond wire drawing die production process is to process the holes on the die blank first, and then insert the die blank into the mold sleeve. The biggest defect of this processing method is that the mold base is processed without any reinforcement, and the mold base is easily broken under the action of ultrasonic equipment; in addition, in order to observe the hole shape, it is necessary to grind a Observe the window. Based on the above two reasons, the traditional processing method has to use a larger size diamond blank, which increases the amount of diamond used, and the price of natural diamond is very expensive, which greatly increases the production cost. Contents of the invention [0003] The purpose of the present i...
