For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of self-feeding press-loading apparatus comprises blanking mechanism, feed mechanism and press-loading device.Blanking mechanism comprises slide block, drift, buffer board and first spring.The lower end of slide block is fixedly connected with drift, and buffer board is connected with the lower end of slide block through first spring.Feed mechanism comprises contiguous block, swinging block, feeding rod and extension spring.The head end of contiguous block is fixedly connected with slide block, and an end of tail end and swinging block flexibly connects.The stage casing of feeding rod is connected with the swinging block axle, and the tail end of feeding rod is connected with swinging block through extension spring.Press-loading device comprises wedge, following wedge, fixed block and second spring.Last wedge is connected with the lower end of slide block, and following wedge is connected through second spring with fixed block.
In preferred embodiment of the utility model, the tail end of contiguous block is provided with roller, and swinging block is provided with chute, roller and chute form fit, and the flexible connection of contiguous block and swinging block is to snap in the chute through roller to realize.
The beneficial effect of the utility model self-feeding press-loading apparatus is: through the design of the structure of the mechanical linkage between blanking mechanism, feed mechanism, the press-loading device; Only need a driving sliding block; Can realize the interlock of three mechanisms, the action of accomplishing feeding, blanking simultaneously and press-fiting.This device control is simple, and pure mechanical movement is easy to safeguard.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Aborning, several same workpiece to be processed is joined together to form raw material band, adds man-hour, need raw material band be transported to the processing district, and workpiece is downcut one by one from the raw material band and press-fits.The utility model self-feeding press-loading apparatus comprises blanking mechanism, feed mechanism and press-loading device, and through external forcing press, once driving can realize a feeding, cutting (blanking) and press-fit.
See also Fig. 1 and Fig. 2, blanking mechanism comprises slide block 1, drift 2, buffer board 3 and first spring 4.Slide block 1 can be done moving of vertical direction along fixing chute under the effect of forcing press.Slide block 1 lower end is fixedly connected with drift 2.Buffer board 3 is connected with slide block 1 lower end through first spring 4.Buffer board 3 is positioned at drift 2 belows, and buffer board is provided with the hole, can hold drift 2 and pass.When slide block 1 descended, it was downward with drift 2 to drive buffer board 3, and buffer board 3 touches the raw material band of bottom earlier, and first spring 4 receives force compresses, and buffer board 3 compresses raw material band.Slide block 1 machine that continues to be stressed drives and to move downward, and drives the hole that drift 2 passes on the buffer board 3 and continues to press down, and thrusts on the raw material band junction between two workpiece, and workpiece is separated with raw material band.
See also Fig. 1, feed mechanism comprises contiguous block 5, swinging block 6, feeding rod 7 and extension spring 8.Contiguous block 5 head ends are fixedly connected with slide block 1, can do the motion of vertical direction with slide block 1.One end of contiguous block 5 tail ends and swinging block 6 flexibly connects.
Particularly, contiguous block 5 is realized through following mode with the flexible connection of swinging block 6: contiguous block 5 tail ends are provided with roller, and swinging block 6 is provided with chute, roller and chute form fit.Roller snaps in the chute.When contiguous block 5 moved up and down under the drive of slide block 1, roller slided in chute, made wobbling action thereby drive swinging block 6.The angle of chute is complementary with the workpiece pitch of the raw material band that send, and guarantees every swing once, and raw material band just in time moves the distance of a workpiece.
The stage casing of feeding rod 7 is connected with 6 of swinging blocks, and feeding rod 7 can connecting axle be the center rotation.The tail end of feeding rod 7 is connected with swinging block 6 through extension spring 8, thereby guarantees the downward workpiece pressing of head end of feeding rod, to guarantee the stability of feeding.When slide block 1 rose, swinging block 6 was to the swing of blanking mechanism direction, and feeding rod 7 is released raw material band to blanking mechanism; When slide block 1 descended, swing arm 6 was to the direction swing away from blanking mechanism, and the head end of extension spring 8 pulling feeding rods 7 discharges the raw material band rollback, thereby realizes action once, and feeding once.
See also Fig. 3, press-loading device comprises wedge 9, following wedge 10, fixed block 11 and second spring 12.Last wedge 9 is connected with the lower end of slide block 1, can under the drive of slide block 1, do the motion of vertical direction.Following wedge 10 is connected through second spring 12 with fixed block 11, can be along the gathering sill horizontal movement.When slide block 1 descends, through blanking mechanism workpiece is cut from the band material earlier, slide block continues tiltedly to carve 9 in the drive and move downward downwards, upward tiltedly carves 9 extruding declivities and carves 10, promotes declivity and carves the motion of 10 along continuous straight runs, thereby realize press-fiting action.When slide block rises, declivity carve 10 lose wedge 9 pressure, initial position rebounds under spring action.
The utility model self-feeding press-loading apparatus has designed the crank connecting link member that is made up of contiguous block 5 and swinging block 6 in feed mechanism, movement in vertical direction is converted into swing, thereby realizes self-feeding.And the press-loading device utilization tiltedly carves movement in vertical direction is converted into horizontal motion, thereby the realization level press-fits.Therefore, under the driving of vertical direction power, this device has been accomplished the work of three directions.
Compared with prior art, the utility model self-feeding press-loading apparatus is simple in structure, is convenient to safeguard pure mechanical movement, easy operating.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
