Abstract
The invention relates to the technical field of composite dies for line-plate forming, in particular to a heart-shaped capel continuous-production die of a line-plate forming machine. The heart-shaped capel continuous-production die of the line-plate forming machine comprises a hole and slot punching area, an edge folding area and a continuous-bending area, wherein the hole and slot punching area, the edge folding area and the continuous-bending area are sequentially arranged according to the process order. According to the heart-shaped capel continuous-production die of the line-plate forming machine, only one die and one line-plate forming machine are needed in the production process, and die machining is easy; all the working procedures are completed through one-time line production, errors caused by manual operation in the working procedures are reduced, and part machining precision is high; and except manual carrying and installing needed when a material belt initially feeds materials and daily maintenance and management, no manual intervention is needed in the rest of procedures, the workload of workers is lowered, and labor cost is reduced.
Description
Technical field
The present invention relates to line plate forming composite die technical field, particularly relate to a kind of line plate forming movement
The continuous production mould of type capel.
Background technology
At present in the suspension of gasification railway contact line at a high speed, it is a kind of common suspension side that dropper connects
Formula.Dropper is by dropper line, cardioid capel, suspension ring, Messenger wire hanging string clamp, contact network messenger wire clamp
Form Deng part.But the production mould of existing cardioid capel includes five secondary moulds, and every secondary mould is corresponding
One stamping machine, and every stamping machine is both needed to an operative, during production, first stainless by original shape
Steel disc stamping-out out, passes sequentially through other several stamping machines just final molding subsequently, and also needs to workman and exist
Carrying semi-finished product or blank between every stamping machine, therefore it is longer to there is the production cycle, production efficiency is relatively low, people
Work cost is high, the problem that labor strength is relatively big and production cost is higher.
It is illustrated in figure 1 the perspective view of the cardioid capel 100 of molding, the material strip of strip rolls over
Bending becomes.
Summary of the invention
The technical problem to be solved in the present invention is: low in order to solve prior art centre type capel production efficiency
Technical problem, the present invention provides a kind of line sheet-forming machine continuous production mould of cardioid capel, with short production cycle,
Production efficiency is high, and cost of labor is low, and labor strength and production cost are the most relatively low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of line sheet-forming machine cardioid capel
Production mould continuously, including the stamping-out hole slot district, flanging district and the continuous bending that set gradually by process sequence
District, described continuous bending district includes disk and charging pressing plate, and described disc centre is fixedly installed fixing mould,
The outer loop-shaped of fixing mould is closed with the inner ring matching form of the cardioid capel of molding, and charging pressing plate is fixed on disk
Center is between disk inner ring, and charging pressing plate is less than the bottommost of fixing mould, and charging pressing plate is towards in disk
Heart side is upper side, and upper side is that horizontal plane is used for carrying material strip,
Described disk be additionally provided with can to disc centre slide the first slide block, the second slide block, the 3rd slide block,
Four-slider and the 5th slide block, described first slide block, the second slide block, the 3rd slide block, Four-slider and the 5th
Slide block is circumferentially provided on disk in order, set described first slide block, the second slide block, the 3rd slide block,
Four-slider and the 5th slide block are front end towards one end of disc centre, and contrary one end is rear end, when described
The front end of one slide block, the second slide block, the 3rd slide block, Four-slider and the 5th slide block slides into disc centre
When fixing the periphery of mould, before the first slide block, the second slide block, the 3rd slide block, Four-slider and the 5th slide block
End can be centered around fixing mould periphery with the shape of cardioid capel outer ring, the first slide block, the second slide block, the 3rd
The rear end of slide block, Four-slider and the 5th slide block is respectively connected with pushing mechanism,
Described continuous production mould also includes that stamping-out cutter, stamping-out cutter are slidably arranged on disk, the fortune of stamping-out cutter
Dynamic direction is mutually perpendicular to the upper side of charging pressing plate, and the upper side of charging pressing plate offers stamping-out groove, stamping-out
Can slide and stretch in stamping-out groove in the front end of cutter, the rear end of stamping-out cutter connects pushing mechanism.

To disk 1 center, it is perpendicular to disk 1 bottom direction and shelters from half-formed band, to prevent in Forging Process
There is being perpendicular to the deformation of disk 1 bottom surface in material strip, and the most half-formed material strip moves to center and fixes mould 3
Lower section, further, the first slide block 41 upwards ejects, and further, the second slide block 42 upwards ejects, and enters one
Step, stamping-out cutter 5 is promoted by cam so that stamping-out cutter 5 front end enters the stamping-out of charging pressing plate 2 upper side
In groove, by material strip severing, further, the 3rd slide block 43 with roller upwards ejects, and folds heart-shaped capel
(i.e. the interlude of material strip) great circle bending bottom 100；Four-slider 44 with roller pushes up downwards further
Go out；Further, the 5th slide block 45 ejects downwards；Material strip is made to form heart-shaped capel 100 in fixing mould 3 periphery
Moulding.After heart-shaped capel 100 moulding terminates, first slide block the 41, second slide block 42, the 3rd slide block 43, the
Four-slider 44 and the 5th slide block 45 are all regained, and three thimbles 9 of fixing mould 3 surrounding stretch out, and heart is embedding
Ring 100 i.e. completes the making of whole part after ejecting.Further, the slip process on disk 1 is by cam
Pushing mechanism 7 has been worked in coordination.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, related work
Personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.
The content that the technical scope of this invention is not limited in description, it is necessary to according to right
Determine its technical scope.
