Special-shaped coal mine cutting pick production equipment and production method employing same

Abstract

The invention discloses special-shaped coal mine cutting pick production equipment and a production method employing the same. The equipment is characterized in that the special-shaped coal mine cutting pick production equipment comprises an upper pressure block, a forming upper mold, a guide sleeve, a forming lower mold, a supporting block, a nitrogen spring and a material return rod which are successively arranged from top to bottom; the forming upper mold is located on the lower side of the upper pressure block; bars are located on the lower side of the pressure block and the inner sides ofthe forming upper mold and the forming lower mold; a material pushing rod is arranged below the bars; the guide sleeve is arranged on the outer sides of the lower portion of the forming lower mold and the upper portion of the forming upper mold; the supporting block is arranged on the outer side of the lower portion of the forming lower mold; and the nitrogen spring is arranged on the lower portion of the forming lower mold. When the special-shaped coal mine cutting pick production equipment is formed, the nitrogen spring is placed on the lower portion of the lower mold. In the extruding process, the upper mold is in contact with the lower mold first and is closed and then is buffered by the nitrogen spring, so that the material flows upward to fill the forming upper mold, thereby achieving the purpose of once forming.

Description

Technical field [0001] The invention relates to the field of coal mine pick manufacturing, in particular to a special-shaped coal mine pick production equipment and a production method using the equipment. Background technique [0002] Due to the complex shape of the special-shaped picks, there are two petals, convex and concave, and the petals are larger in shape. According to the traditional process, blanking, pre-forming, and procedures are required to ensure that the desired shape is achieved during forming and the petals are full. Therefore, the current general production process of special-shaped coal mine picks is: straightening → centerless turning → straightening and calendering → centerless grinding → sawing → blank making → shot blasting → coating → heating → preforming → forming → temperature control cooling → Shot blasting→magnetic particle inspection→car outer circle, taking length, cutting groove→taking length, car handle→stamping→jumping sorting→packing. The disa...

Problems solved by technology

The disadvantages of the secondary process are: there are billet making, preforming, and other processes in the process. In the production process, due to the need for billet making, the blanking weight is heavy, which increases the material cost, numerical control cost, labor cost, and the production cycle time is very long.

The pre-forming process increases the cost of molds, labor costs, and equipment costs for using hydraulic presses and prolongs the production cycle

These two processes directly affect the production cycle and production cost of the product
