High efficiency track spike die

Abstract

The invention discloses a high efficiency track spike die. The die includes an upper die and a lower die, and the lower die is provided with a die hole. The high efficiency track spike die is characterized in that the die further includes an upper face plate, a lower bottom plate, and two connection rollers; the top surface of the upper die is provided with an extra material cutter; the upper dieis fixed on the lower surface of the upper face plate; two ends of the upper face plate are respectively fixed on the two connection rollers; the bottom surface of the lower die is provided with an arc-shaped groove; the lower die is composed of two die plates; the bottoms of the two die plates are slidably connected with the lower bottom plate; the two ends of the lower bottom plate are respectively slidably connected to the two connection rollers; driving devices are separately disposed between the two die plates and the two connection rollers; the inner walls of the upper die and the lowerdie are provided with wear resistance layers; each of the wear resistance layers includes, by weight, 25-30 parts of scrap steel, 5-7 parts of ferrovanadium, 6-10 parts of ferrotitanium, 10-15 parts of ferroboron, 6-10 parts of high bauxite, 6-9 parts of silicon-calcium-barium, and 10-15 parts of quartz sand; and an ejector rod is disposed at the bottom of the lower die, the top surface of the ejector rod communicates with the die hole, and the bottom surface of the ejector rod is provided with a power device. The high efficiency track spike die is novel in design, is convenient to operate andis high in production efficiency.

Description

technical field [0001] The invention relates to a mold, in particular to a high-efficiency road stud mold. Background technique [0002] Spikes are commonly used fasteners for rails and are used to fasten rails to sleepers. Most of the road studs produced by the Ministry of Railways need standard size and standard thickness. The existing method of making road studs is to cut the steel bar into a fixed length, quench one end of the steel bar, heat it at high temperature, and then hot stamp it to form a road stud. As for the nail head, the formed road nail head needs to be carefully polished to meet the requirements of use. The grinding process is time-consuming and laborious, and the grinding efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency road stud mold with novel design, convenient operation and high production efficiency. [0004] In order to achieve the above object, the technical solution adopt...
