Sectional material dressing die

Abstract

The invention discloses a sectional material dressing die. The sectional material dressing die comprises an upper die plate, a lower die plate and guide posts arranged between the upper die plate and the lower die plate. The lower end of the upper die plate is connected with a fixing plate. An upper pressing head is connected with the lower end of the fixing plate. A concave die body is connected with the upper end of the lower die plate. The sectional material dressing die is characterized in that a die core is arranged in the concave die; a plurality of cutting tools are evenly distributed in the vertical direction of the die core at intervals; the cutting tools are provided with tool edges matched with the contours of workpieces; the anterior angle of the cutting tools is 15-25 degrees, and the relief angle of the cutting tools is 0.5-1.5 degrees. According to the sectional material dressing die, the multiple cutting tools are evenly distributed in the vertical direction of the die core of the concave die at intervals, and thus layered cutting of the workpieces can be conducted without adopting multiple pairs of dies and the cost is reduced. In addition, the dressing efficiency is improved, and dressing can be completed at a time. Dressed section materials are good in surface smoothness, high in size precision, less in product vertical flash and high in product qualified rate.

Description

technical field [0001] The invention relates to a mold, in particular to a profile shaping mold. Background technique [0002] Nowadays, copper and aluminum extrusion products are more and more widely used, and they are found in the fields of automobiles, electronics, building materials, and even aerospace, and they have played an important role in all walks of life. However, with the development of technology, the precision of traditional extruded profiles has been difficult to meet the requirements, and it cannot meet the customer's requirements for precision. Therefore, it needs to be finely shaped before it can be used. [0003] At present, the more mature and commonly used shaping method is to use tungsten steel mold shaping. Such as figure 1 As shown, it is a structural schematic diagram of a profile. The size of this profile is too large. In order to meet the precision requirements, multi-stage pressing is often required. Therefore, multiple molds must be used for p...
