Abstract

The utility model relates to a metal wire processing device used for fabricating a spring washer, which is provided with a feeder with a clamp, and the feeder with a clamp is driven by an eccentric connecting rod, the clamping and the looseness of the clamp is controlled by a cam and a lever mechanism, the length of the feeder can be regulated in a stepless way, and the feeding is accurate. A spring coil is shaped by winding by the method that a circle arc-shaped winding device is matched with a core shaft, and the dimensional precision is high. For a cutting mechanism, the eccentric connecting rod is slickly matched with a crank mechanism to enable the cutting edge of a movable cutter to move along a special track, and the movable cutter can cut off the spring coil together with a fixed cutter; the cut surface is flat, and the incision is uniform; thus, a sleeve ring and a lap of the spring washer can be eliminated.

Description

Forming machine for spring washer

The utility model relates to a kind of metal wire rod processing or pressworking equipment, is specially adapted to the automatic processing and manufacturing of spring washer.

Existing spring washer contour machining equipment, be that the continuous or silent feeding of number pair roller is adopted in the coiling and the cut-out of spring coil, the roller liftout is reeled, and a plurality of cutting knifes and the continuous rolling cut moulding of coiling mandrel of band blade or the coiling mandrel punching molding of reciprocating cutting knife and band blade are installed on cutter plate.The spring washer feeding of adopting above-mentioned process equipment to produce is inaccurate, the section out-of-flatness, and the otch size is uneven, and dimensional accuracy is low, is easy to the collar and joining seam, and fault is difficult to judge inconvenient multicomputer management.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides a kind of feeding accurate, and section is smooth, and otch is even, can avoid the novel spring packing ring make-up machine of the spring washer collar, joining seam.

Technical solution of the present utility model is achieved in that a kind of spring washer make-up machine that is used for metal wire rod processing, is made up of support, transmission mechanism, feed mechanism, winding mechanism, shut-off mechanism.Special character of the present utility model is: feed mechanism is by reciprocating feeding slide block 10, is contained in the stock guide 6 before the feeding slide block 10 and is installed in clamp 8 on the feeding slide block 10, clamps little cam 9 and forms.Feeding slide block 10 connects with the eccentric ratio driving mechanism, the clamping of clamp and unclamp action and realize by cam 18, connecting rod 11, lever 15 and cam 9, and control feeding length and slide block front and back position are realized by eccentric 14, connecting rod 12; Cam 24 compresses wire rod when the slide block backhaul by arresting lever 7.Winding mechanism is made up of coiler 1, other glassware 2, mandrel 3, material road 4; Coiler 1 is the arc-shaped surface contact with contacting of spring coil.Shut-off mechanism is by being contained in the fixed cutting tool 5 on the frame and being made up of the moving cutting knife 36 of eccentric ratio reciprocating mechanism control; Moving cutting knife 36 passes through crankshaft eccentric wheel 23, the connecting

rod

21,22 of eccentric ratio reciprocating mechanism, crank throw 33,35, and the action of knife bar 34 realizes disconnected spring coil with fixed cutting tool.

The advantage that the utility model is compared with prior art had is: because under same driven by motor, the feeding slide block 10 of feed mechanism advances, the control of backstroke and clamp 8 are tight with feed collet, the control of unclamping is respectively by the control that cooperatively interacts of different eccentric ratio driving mechanisms and cam-and-, and the length of feeding eccentric wheel 14 stepless adjustment, the front and back position of slide block 10 can be adjusted with connecting rod 12, cam 24 compresses material by arresting lever 7 during backstroke, stock guide 6 can prevent material bending, therefore improved pushing precision, stablized duty, make the spring coil otch even, eliminated the possibility of the spring washer collar and joining seam.

Circular arc is planar to be contacted because the coiler 1 of winding mechanism is with mandrel 3 and the spring coil that is bent moulding simultaneously, changed roller liftout coiling in the prior art, spring coil is the situation that line contacts with roller, the gap between 2 pairs of spring coils of other in addition glassware and the adjustment of axial location make spring washer moulding rule, dimensional accuracy height.Again because shut-off mechanism of the present utility model is to adopt to be loaded on the blade of the moving cutting knife 36 in the knife bar 34 along a special orbiting motion, and spring coil is cut off with fixed cutting tool 5 relative motions, its impulse stroke near linear has guaranteed that the spring coil otch is smooth, does not scratch contiguous spring coil.

The utility model is described in further detail below in conjunction with accompanying drawing:

Motor 26 rotates eccentric wheel 14,

cam

gear

27,28,19,13,20,16,17, also makes bent axle and eccentric 23 rotations simultaneously.Eccentric wheel 14 makes feeding slide block 10 reciprocating by connecting rod 12, and clamp is tight with feed collet during forward stroke, during backstroke material is unclamped the clamping of clamp and unclamping by cam 18, connecting rod 11, lever 15 and cam 9 controls.Eccentric wheel 14 can be to the stepless adjustment of feeding length, connecting rod 12 can be adjusted the front and back position of slide block 10, and when feeding slide block 10 backstrokes, cam 24 compresses material by arresting lever 7, stock guide 6 can prevent material bending, and it moves back and forth under slide block 10 and spring action.

The material of being sent here by clamp 8 passes through material road 4, brake forming between arc coiler 1 and mandrel 3, and other glassware 2 can be used to adjust gap and the position of spring coil on mandrel 3 between the spring coil.Mandrel 3 is bearing on two rolling bearings, and can do axially to adjust.

Bent axle and eccentric wheel 23 are respectively by connecting

rod

22,21, and crank throw 33,35 makes knife bar 34 motions, and the blade that is loaded on the moving cutting knife 36 in the knife bar 34 is along as shown in the figure orbiting motion, and to make impulse stroke ab section be a near linear.When the clamp backstroke, moving cutting knife 36 stretches in the spring coil and with fixed cutting tool 5 spring coil is cut off, and forms spring washer.

Handle 32 can make lathe manual after slowing down by

gear
