Description
Technical field
The utility model belongs to universal machine technical field, belongs to plate shearing machine technical field further, and be specifically related to a kind of structure simply, processing ease, reliable operation, can reduce the plate shearing machine cutter clearance adjusting device of upper tool post and rail friction.
Background technology
In machinery manufacturing industry, plate shearing machine is a kind of conventional process equipment, be mainly used in the shearing blanking of sheet material workpiece, it has easy and simple to handle, that operating efficiency is high feature, and plate shearing machine is widely used in the cutting member processing of the industries such as common mechanical manufacture, automobile, Production Container, device for switching and light industry.Although the plate shearing machine kind of current use is more, from operation principle and structural shape, be similar substantially, generally that lower slide is fixed, power passes to upper tool post through bent axle, and upper tool post moves up and down in rail plate, completes the shearing to workpiece.Plate shearing machine in use has strict requirement to the gap between upper bottom tool, needs to adjust gap between upper bottom tool according to the different-thickness of workpiece.Because the size in upper bottom tool gap not only affects the presentation quality of workpiece shear surface, and excesssive gap or too smallly also directly can damage cutter, even damage equipment.The plate shearing machine of prior art, on it bottom tool gap size by adjustment lower slide realize, upper tool post and guide rail constant.When needing to adjust upper bottom tool gap, the connecting bolt of lower slide and frame need be unclamped, then bottom tool gap adjustment bolt is adjusted, cutter gap is increased or reduces, the size clearance gauge in cutter gap is measured, tighten the connecting bolt of lower slide and frame behind adjusting play to suitable numerical value, then lock Cutter Gap adjustment bolt.This Cutter Gap adjustment procedure is loaded down with trivial details, the measurement in gap is inconvenient, require that the quality of operating personnel is higher, whole operating process is wasted time and energy, when needs carry out small lot variation production, owing to adjusting cutter gap continually, must increase and produce non-cutting time, thus affect production efficiency.
Owing to when plate shearing machine works being single-blade bias shearing workpiece, so have a lateral pressure in the side of fixing a cutting tool, there is certain assemblage gap between upper tool post and guide rail simultaneously, under the effect of lateral pressure, upper tool post swings formation drift angle backward, formed upper tool post a side only with relative shim lower contacts, cutter actual gap is bigger than normal than measurement clearance, and along with shim wearing and tearing increase, gap deviation value also increases thereupon.In order to ensure cutter gap actual value and measured value basically identical, when shim may wear to a certain degree, just must change shim.And to change shim be also a more loaded down with trivial details process.Under normal service condition, within general 2 ~ 3 months, just shim need be changed.So the plate shearing machine of prior art, upper and lower Cutter Gap adjustment is loaded down with trivial details, and spare parts consumption is large, and labor strength is high, and production efficiency is low, has had a strong impact on the economic benefit of enterprise.For this reason, research and develop a kind of structure simple, processing ease, reliable operation, the plate shearing machine cutter clearance adjusting device that can reduce upper tool post and rail friction is the key addressed this problem.
