Description
Technical field
The utility model relates to the technical field of basic part machining, in particular a kind of chain plate hole of carrier bar squeezes aperture apparatus.
Background technology
In chain industry at home, the processing technology of the Chain plate plate hole of large gauge has following three kinds of techniques usually: 1) essence punching; 2) punching, two punchings; 3) impact extrusion.The euphotic belt of the chain plate hole of fine blanking technology can only reach more than 60%, and bright degree is general.One punching, two is rushed technique euphotic belt and is reached more than 80%, and bright degree is better.The euphotic belt of impact extrusion technique reaches more than 90%, and bright degree is better, but it is higher to make requirement to impact extrusion nail, and in process, the easily wearing and tearing of impact extrusion nail, make production cost increase thereupon; And the Chain plate distortion of impact extrusion technique is serious, the perpendicularity in hole is poor, and to sum up three kinds of techniques, respectively have advantage, respectively have shortcoming, but the euphotic belt that all can not meet chain plate hole reaches more than 95%.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the chain plate hole providing a kind of carrier bar squeezes aperture apparatus, the technical problems such as existing chain plate hole bright degree is poor, equipment requirement is high to solve, Chain plate is out of shape, the perpendicularity difference in hole.
The utility model is achieved through the following technical solutions:
The chain plate hole that the utility model provides a kind of carrier bar squeezes aperture apparatus, described carrier bar comprises two chain plate holes, and described crowded aperture apparatus comprises upper die structure, lower die structure, punch press and steel ball, and described lower die structure is positioned at the below of upper die structure, driven by punch press and move to lower die structure, wherein:
Described upper die structure comprises the cope match-plate pattern 1, upper padding plate 2, nail seat 3 and the crowded hole nail 4 that are from top to bottom fixedly connected sequentially; Described crowded hole nail 4 is provided with two, is vertical at bottom nail seat 3, and these two crowded hole nails 4 are positioned on same axis with two chain plate holes of carrier bar to be processed respectively;
Described lower die structure comprises the locating piece 5, lower bolster 6, rest pad 7 and the lower bolster 8 that from top to bottom set gradually, described locating piece 5 is provided with the detent mated with carrier bar to be processed, described lower bolster 6 is provided with two slotted eyes, two slotted eyes of described lower bolster 6 are positioned on same axis with two chain plate holes of carrier bar to be processed respectively, and its diameter is greater than steel ball size;
Described steel ball is located on two chain plate holes of carrier bar to be processed, and its hardness is more than 58HRC, and its diameter is greater than the carrier bar bore dia 0.1-0.3mm of carrier bar to be processed.
Further preferably, described steel ball scribbles punching drawing oil, to prevent hole surface by plucking, can cooling effect be played again.
The utility model has the following advantages compared to existing technology: the chain plate hole that the utility model provides a kind of carrier bar squeezes aperture apparatus, the chain plate hole bright degree utilizing this device to obtain is as minute surface, its chain plate hole euphotic belt can reach more than 95%, and the perpendicularity of chain plate hole is good, Chain plate distortion is little, process stabilizing.

Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
The chain plate hole that the utility model provides a kind of carrier bar squeezes aperture apparatus, for a kind of Special chain plate hole squeezes aperture apparatus, there is structure as illustrated in fig. 1 and 2, described carrier bar comprises two chain plate holes, described crowded aperture apparatus comprises upper die structure, lower die structure, punch press and steel ball, described lower die structure is positioned at the below of upper die structure, is driven move to lower die structure by punch press, wherein:
Described upper die structure comprises the cope match-plate pattern 1, upper padding plate 2, nail seat 3 and the crowded hole nail 4 that are from top to bottom fixedly connected sequentially; Described crowded hole nail 4 is provided with two, is vertical at bottom nail seat 3, and these two crowded hole nails 4 are positioned on same axis with two chain plate holes of carrier bar to be processed respectively;
Described lower die structure comprises the locating piece 5, lower bolster 6, rest pad 7 and the lower bolster 8 that from top to bottom set gradually, described locating piece 5 is provided with the detent mated with carrier bar to be processed, described lower bolster 6 is provided with two slotted eyes, two slotted eyes of described lower bolster 6 are positioned on same axis with two chain plate holes of carrier bar to be processed respectively, and its diameter is greater than steel ball size;
Described steel ball is located on two chain plate holes of carrier bar to be processed, and its hardness is more than 58HRC, and its diameter is greater than the carrier bar bore dia 0.1-0.3mm of carrier bar to be processed, and described steel ball scribbles punching drawing oil, to prevent hole surface by plucking, can play cooling effect again.
In the carrier bar hole machined process of carrier bar, first treat processing carrier bar and carry out punching, the aperture of punching should be less than the 0.1-0.3mm in finished product chain plate hole aperture, then crowded hole is carried out with above-mentioned crowded aperture apparatus, be specially: the carrier bar to be processed carrying out punching process is located in the detent of locating piece 5, steel ball is placed by the chain plate hole of carrier bar to be processed, steel ball surface scribbles punching drawing oil, punch press starts, slider of punch moves down, squeezing hole nail 4 is pressed in chain plate hole by steel ball, steel ball falls the slotted eye place at lower bolster 6 by chain plate hole, complete crowded hole, steel ball takes out from the slotted eye of lower bolster 6, reusable.Utilize this special crowded aperture apparatus, can ensure that the perpendicularity of chain plate hole is good, Chain plate distortion is little, process stabilizing.
