Detailed description of the invention
Embodiment one
The machine tool structure that the present embodiment is processed based on baric systerm progressive molding is as shown in Fig. 1 and Fig. 1, lathe bed 1 work top of bottom fixes portal frame 2, and portal frame 2 has the vertical brace 2-1 of longitudinal slide rail by both sides end face and to be supported on the vertical brace 2-1 of both sides and to form with the crossbeam 2-2 that longitudinal slide rail forms moving sets.Crossbeam 2-2 is equipped with form with it and moves horizontally secondary planker 3, planker 3 is equipped with the toolframe 4 forming with it vertical moving sets, toolframe 4 is equipped with the motor as tool heads drive unit, the main shaft 6 of this motor and lower end erecting tools head 7 is in transmission connection.The travel mechanism that each moving sets is driven by corresponding motor respectively---be generally screw mechanism and drive, therefore tool heads controlled realization longitudinal direction, horizontal and vertical three-dimensional displacement can be made, complete the movement locus that machining needs, and by self rotation, make workpiece progressive molding.
Settle the shears 9 of rectangular frame above the workbench 1-1 of lathe bed 1, this shears 9 is installed the workpiece support clamping device 9-1 with inverted T-shaped chute, workpiece support clamping device 9-1 compresses the brace table 8 of top clamping work pieces 10 by pressing plate.
As shown in Figure 3, be rectangle frame structure, its corner is fixedly connected with vertical guide pillar 9-2 respectively by four interference fit holes the concrete structure of shears 9.Form moving sets in the vertical guide pin bushing 9-3 of linear bearing that vertical guide pillar 9-2 plug-in mounting is fixed in lathe bed 1 installing hole in use, linear bearing adopts flange extended type, thus is easy to guarantee four guide pillars and has enough depth of parallelisms.
Two opposite side middle lower surface of crane 9 and the piston upper end of vertical stainless steel cylinder 5 are commonly called as flake joint by ball pivot head 9-4() hinged, the cylinder body lower end hinge of stainless steel cylinder 5 is contained on bed piece 1.Like this lifting is driven and be separated with guiding, not only reduce the installation difficulty of cylinder, the more important thing is that cylinder can have the free degree by a small margin by guide pillar relatively, thus can not produce with the guiding of guide pillar and conflict, catching phenomenon when effectively stopping mobile.
The gas circuit of the present embodiment as shown in Figure 4, after the treating apparatus A2 that compressed air source A1 is consisted of filter etc. and air inflow control valve A3, met cavity of resorption (5 in A7 and Fig. 3 of two cylinder body A7 in parallel by the gas circuit being provided with bypass gas bomb A10 after 3-position 4-way transfer valve A5, for convenience of expressing, be inverted at upper cylinder body in Fig. 4), the epicoele of two cylinder body A7 connects air by muffler A6.Parallel-connection structure makes two cylinder pressures be consistent, ensure crane when rising or decline action continuous and stable, not block time.When 3-position 4-way transfer valve is in primary importance, cylinder body cavity of resorption connects compressed air source, crane jacking; When 3-position 4-way transfer valve is in the second place, cut off all gas circuits, cylinder body is in maintenance inactive state; When 3-position 4-way transfer valve is in the 3rd position, cylinder body cavity of resorption connects air through exhaust gas flow control valve A4 and another muffler, and crane declines.Therefore, conveniently by the state of control cylinder, the servo-actuated lifting of workpiece can be realized.
In addition, the progressive molding lathe of the present embodiment is also equipped with electrical heating power supply 11, the two poles of the earth of this power supply are electrically connected with workpiece 10 and tool heads 7 respectively by connector and pressure holding piece, and 12 in figure, 13,14 is respectively pressing plate felt pad, brace table felt pad and tool heads insulation sleeve.Therefore can electrified regulation as required, thus by electrocaloric effect, be convenient to progressive molding.
Add man-hour, the progressive molding machine tool head downforce of the present embodiment is carried on the crane of cylinder supports, essence constitutes air-flotation type and supports, owing to being provided with the bypass gas bomb playing pressure stabilization function in the feeding pneumatic of cylinder, the specific gravity of gas that the employing of this caisson makes feeding compress is very little, pressure is almost constant, in corresponding tool head vertical feed servomechanism process, both are made reasonably to organically combine, can automatically adjust in time, dynamic touch pressure between retaining tool head and workpiece is stablized, thus with simple structure for ensureing that progressive molding crudy has established good basis.In addition, the interference fit of corner guide pillar and crane and guide pillar reliably can complete elevating movement reposefully with coordinating of linear bearing.Although progressive molding can produce side force to plate shape workpiece, the present embodiment structure and high-precision linear bearing effectively can prevent the mechanism blockage because side force causes, and improve the precision of drip molding.The below that guide pillar is positioned at crane also avoid interferes with the range of movement of tool heads, expands the effective travel of lathe, can the size of formation of parts larger.While having above-mentioned advantage, the present embodiment also significantly lower in manufacturing cost and assembly difficulty.
