Material falling device

Abstract

The invention relates to a material falling device, which is used for receiving heat forming parts in the metal heat processing process. The material falling device comprises a material collecting part and a support frame, wherein the material collecting part is formed by metal wires arranged at intervals; the metal wires are made of Ni-based alloys with the Fe content (weight percentage) being 10to 16 percent; the heat forming part is a cam shaft; the metal heat processing is wedge transverse milling processing. The material falling device also comprises a slide plate part, wherein the slideplate part is connected with one end, near a wedge transverse milling machine, of the support frame; the bottom of one end, near the wedge transverse milling machine, of the support frame is hinged to a ground supporter arranged on the ground through a hinging frame; the bottom of one end, far away from the wedge transverse milling machine, of the support frame is hinged to the end part of a piston rod of a lifting cylinder through a hinging block; a cooling groove is put in the bottom of the support frame; cooling water is contained in the cooling groove.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a blanking device, which can be used in forging or rolling production lines to prevent bumps on product surfaces. Background technique [0002] Both forging and rolling are commonly used processes for thermal processing of metal profiles. Forging is to use impact force or pressure to deform the metal between the iron or forging die, so as to obtain forgings of the required shape and size. Rolling is to pass the metal blank through a For the gap (various shapes) of rotating rolls, due to the compression of the rolls, the material section is reduced and the length is increased. The pressure processing method, forging and rolling are all important forming methods of metal parts, which can ensure that metal parts have Good mechanical properties to meet the requirements of use.

Problems solved by technology

[0004] The main defect of the above-mentioned blanking device in use is: when the camshaft 4 falls from the slide part 1 on the material receiving part 2, since the camshaft 4 is still a high-temperature red-hot part, the surface does not have sufficient hardness, and it is easy to It directly collides with the material receiving plate of the material receiving part 2 to cause bump damage. These bump damage will affect the appearance of the parts and require additional subsequent grinding. In serious cases, the product will be scrapped due to insufficient follow-up processing allowance. On the one hand, it is also because the camshaft 4 is still a high-temperature red hot part. After falling onto the material receiving plate of the material receiving part 2, the parts and the material receiving plate have a large heat exchange area, and it is difficult to apply cooling means, and the material receiving plate is very large. Fast distortion and deformation, so it is easier to collide with the product, and needs to be replaced very frequently, which greatly increases the production cost
