Automatic vacuum packing machine centralized processing
Automatic vacuum packing machine is a kind of packing machine which can save labor or do not need manual operation and has vacuum sealing function.At present, everything is efficient, so is assembling a fully automatic vacuum packing machine.Centralized processing is one of the main development directions of modern packaging machining.The following look at the automatic vacuum packaging machine centralized processing process.
Automatic vacuum packaging machine centralized processing process is the use of a variety of different appliances, in the frame at the same time processing one or several different surfaces of the workpiece.In the frame body is usually selected multi - axis, multi - surface, multi - station and composite tools and other methods to focus on processing.
If the automatic vacuum packing machine adopts multi-position drum machine to process large box parts, the effect is obvious from the point of view of centralized process and reducing the number of machine tools.A drum wheel machine tool for processing the front beam of the puller is designed to process this larger box part.When the drum wheel turns the position produces the very big high force, specially in starts the processing, the drum wheel only installs a work piece, the rotary drum wheel is very unbalanced, does not break the drum wheel drive mechanism the capacity.Therefore, when improving the degree of process concentration, we should fully consider its influence on machine productivity, machining accuracy, working reliability, convenience of using adjustment and so on.The following is to talk about the specific determination of the concentration of machine tool process should pay attention to the problem:
(1) consider appropriate automatic vacuum packaging machine centralized processing work procedure under the condition of reliable, single focus should be the same process in the same location or on a machine tool processing, such as in processing box of modular machine tool assembly line, often will be on the box body, let a large number of tapping process focus on special tapping modular machine tool.The surface is not with a large number of knots, the sharp hole process concentrated in a spindle box into a machine so that the machine tool junction is more reasonable.
Generally, lubrication is required when tapping. The tapping is concentrated on a machine to facilitate centralized lubrication and recovery of lubricating fluid. Meanwhile, reverse is required when tapping returns.In addition, tapping cycle time is very short, specialized processing, because not subject to the cycle time long process constraints, automatic vacuum packaging machine productivity can be increased.
For small diameter deep hole drilling, usually should also focus on a special deep hole drilling machine, and not with drilling a shallow hole in a machine tool processing.In this way, the deep hole drilling machine is designed in formation to facilitate screen layout and improve the productivity of drilling shallow holes.
A lot of drilling and boring can be separated, do not concentrate on a spindle box processing.Because of the large diameter of the junction hole and the basket hole, the rotation speed often has a big difference, which makes the spindle box drive chain complex.This is especially true when there are many small holes to be drilled around the mirror hole.Well and make boring tool adjustment inconvenience.In addition, a large number of drilling produces a large axial thrust, which may tilt the workpiece and affect the precision of boring.If the clamping pressure is increased, it will cause serious deformation of the workpiece.At the same time, the hole according to the movement is too, in turn affect drilling, especially small diameter drill increased the possibility of fracture.
In addition, the dumpling hole feed is large, cutting speed is low.High cutting accuracy for boring and small feed.So the dumpling hole and slag hole are not concentrated in a spindle box.Because it has a negative impact on the structure of the spindle box, the reasonable choice of cutting parameters.
