Riser hammer test device

Abstract

A riser hammer test device, which includes a base, the base is composed of a number of beams and longitudinal beams welded together, it is characterized by two sample sleeves welded on the base beams, the outer side of the sample sleeve is from top to bottom There are three pairs of clamping plates arranged horizontally to weld the sample sleeve and the beam together, and the clamping plate is provided with an arc-shaped groove that matches the shape of the outer wall of the sample sleeve; the upper plane of the sample sleeve is flush with the upper plane of the base , place an adjustment sleeve in one of the sample sleeves, the outer diameter of the adjustment sleeve is consistent with the inner diameter of the sample sleeve, the inner diameter of the adjustment sleeve is consistent with the diameter of the damaged sample, and there are pin holes on the sample sleeve and the adjustment sleeve.

Description

technical field [0001] The application belongs to the field of foundry machinery, and relates to a test device for riser removal equipment in the post-treatment process of castings. Background technique [0002] In the casting production process of the foundry industry, especially the production of large castings, the removal of the sprue and riser has always been a difficult problem. Traditionally, gas cutting, manual hammering with a sledgehammer, or the use of a crane to hoist a metal weight to hit the riser will cause problems such as energy consumption, casting quality damage, low efficiency, and unsafety. In order to solve this difficult problem, a kind of riser removal hammer is adopted to remove the riser now. Align the casing of the de-riser hammer with the riser, press the button valve, the piston rod will rush out from the casing, and break the riser with enough energy. Before selling the riser hammer, the size of the impact energy, the diameter of the riser of ...

Problems solved by technology

Previously, a cylinder whose inner diameter was the same as the diameter of the lead column sample and whose height was one third of the diameter of the lead column sample was fixed on the vertical plate, and the lead column sample was directly placed in the cylinder, which solved the problem of the lead column. The problem is that the sample is placed horizontally, but after hitting the lead column sample, the diameter of the bottom of the lead column will become larger, and the existence of the cylinder will limit the expansion of the bottom of the lead column, which will result in the authenticity of the height of the lead column after one hit
