Abstract

The invention discloses a kind of blanking method of carrier bar, is related to carrier bar punch press process technical field, solves the problems, such as that the punching cost of existing carrier bar is high.The blanking method includes step:Hang → enclose trimming circle material and remove packing → feeding → pinch machine feeding feeding → punch press unlatching → charging → pre-punched hole → carrier bar profile semishearing → fine blanking hole → blanking → waste material cutting in uncoiling frame → craft.When carrier bar is punched, after preparation, machine starts normal work, it is punched out with punch, circle material is punched first by 80% punching in aperture, then with punch-die, then carrier bar profile is carried out being punched formation process mouth, punching using incomplete blanking and carries out smoothing shaping to carrier bar flatness, then carries out fine blanking hole with fine nail, and aperture is punched by product demand aperture.The present invention improves the euphotic belt of carrier bar and the perpendicularity of carrier bar without individually squeezing hole process.

Description

A kind of blanking method of carrier bar
Technical field
The present invention relates to carrier bar punch press process technical field, more particularly to one kind need not individually squeeze hole process, can be significantly Lift the blanking method of carrier bar euphotic belt and the carrier bar of carrier bar perpendicularity.
Background technology
At present, some carrier bars are required for first blanking, printing, smoothing shaping, then carry out squeezing hole process, and ensure carrier bar light Band and lifting chain performance are, it is necessary to design more molds, and need many times to go to debug mould.Not only waste of manpower thing Power, and cost is high for end user, low production efficiency.
The content of the invention
To solve the defects of above-mentioned technology is present, the invention provides a kind of without individually squeezing hole process, can significantly carry Rise the blanking method of carrier bar euphotic belt and the carrier bar of carrier bar perpendicularity.
Technical scheme is used by the present invention realizes above-mentioned technique effect:
A kind of blanking method of carrier bar, including step:Hang → enclose trimming circle material in uncoiling frame → craft remove packing → Feeding → pinch machine feeding feeding → punch press unlatching → charging → pre-punched hole → carrier bar profile semishearing → fine blanking hole → blanking → useless Material is cut.
A kind of blanking method of above-mentioned carrier bar, pre-punched hole is carried out with pre- punch in pre-punched hole process, by the 80% of aperture Punching, then circle material is punched with punch-die, then carrier bar profile is carried out to be punched formation process mouth, punching is using incomplete Blanking.
A kind of blanking method of above-mentioned carrier bar, smoothing shaping is carried out to carrier bar flatness before fine blanking hole process is carried out, Then fine blanking hole is carried out with fine nail, proportionately product demand aperture is punched to aperture.
The present invention compared with prior art, has advantages below and effect:This method production efficiency is high, can lift product matter Amount, easily operate, fine blanking hole substitutes original crowded hole process completely, improves production efficiency, shortens the process-cycle, improves carrier bar Euphotic belt and carrier bar perpendicularity, reduce processing cost, while can meet and improve chain performance.After punch press process Flight edge is without misrun, fleshiness, and the carrier bar flatness after punching reaches 0.1, and the chain plate hole heart is no more than 0.015mm, energy away from scattered error Meet the production requirement of high-precision chain.
Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, in conjunction with specific embodiment The present invention is explained in detail.
The invention discloses a kind of blanking method of carrier bar, including step:Trimming circle material is hung → enclosed in uncoiling frame → hand Work removes packing → feeding → pinch machine feeding feeding → punch press unlatching → charging → pre-punched hole → carrier bar profile semishearing → fine Hole → blanking → waste material is cut.Pre-punched hole is carried out with pre- punch in pre-punched hole process, by 80% punching in aperture, then uses punch-die Circle material is punched, then carrier bar profile is carried out to be punched formation process mouth, punching uses incomplete blanking.Carrying out fine Smoothing shaping is carried out to carrier bar flatness before the process of hole, then fine blanking hole is carried out with fine nail, to aperture proportionately product demand aperture Punching.
Carrier bar punching is 70.3mm available for raw material width, and thickness is 3.25-4mm sheet material, can be according to different-thickness With material trimming circle material, ensure the carrier bar euphotic belt after punching more than 85%, edge is without misrun, fleshiness.Carrier bar after punching Flatness reaches 0.1, and a mould three, the chain plate hole heart is no more than 0.015mm away from scattered error, can meet the production requirement of high-precision chain. This method production efficiency is high, can Improving The Quality of Products, easily operation, reduce rear road and squeeze hole process, it is ensured that the light of carrier bar The perpendicularity of band and carrier bar, reduces the cost of processing punching, while can meet and lifting chain performance.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry For personnel it should be appreciated that the present invention is not limited to the above embodiments, that described in above-described embodiment and specification is the present invention Principle, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these change and Improvement is both fallen within the range of claimed invention, the protection domains of application claims by appended claims and its Equivalent defines.
