Abstract
The utility model discloses an it prevents material returned structure to upgrade mould, take and prevent material returned device including the material, prevent material returned unit bit in material area side, the material is taken and is equipped with the breach, the breach is located material band edge side, prevent being equipped with on the material returned device and prevent material returned mouth, prevent being equipped with in the material returned mouth locking piece and spring, the spring connects in locking piece below, breach and locking piece all are half trapezoidal setting, and to go to the bottom the direction unanimous with the advancing direction in material area, this it prevents material returned structure to upgrade mould can the protective film utensil, avoids the material area to retreat.
Description
Technical field
The utility model relates to a kind of level progressive die anti-back material structure.
Background technology
Level progressive die (being also the progressive die) is made up of multiple station, and each station has associated different processing in order, completes a series of different punch process in the rountrip of punch press. After rountrip completes, according to a fixing step pitch, material is moved forward by punch press feeder, like this multiple operation can be completed on secondary mould, generally have punching, blanking, bending, trimming, stretching etc.
Level progressive die affects product quality owing to drawing back when the vibration material strip of the deadweight of material strip and punch press has after having sent material in the process that mould sweeps away, and can rush bad mould time serious.
Practical novel content
The technical problems to be solved in the utility model is to provide one can protect mould, avoids the level progressive die anti-back material structure that material strip retreats.
For solving the problem, the utility model adopts following technical scheme:
A kind of level progressive die anti-back material structure, comprise material strip and anti-discharging device, described anti-discharging device is positioned at material strip side, described material strip is provided with breach, described breach is positioned at material strip avris, and described anti-discharging device is provided with anti-material returned mouth, is provided with stop block and spring in described anti-material returned mouth, described spring is connected to below stop block, and the traveling direction that described breach is all half trapezoidal setting and go to the bottom direction and material strip with stop block is consistent.
As preferably, described stop block is fixedly connected with spring.
As preferably, described spring is arranged at anti-material returned mouth internal fixtion.
As preferably, the size of described breach is consistent with stop block.
As preferably, described breach is provided with more than one.
The beneficial effects of the utility model are: arrange breach on material strip, and coordinate the stop block of a band spring, form the anti-material returned structure of unidirectional restriction of advancing, thus protect mould when not affecting operation.
Accompanying drawing explanation
Fig. 1 is the one-piece construction figure of the utility model a kind of grade of progressive die anti-back material structure;
Fig. 2 is the running status figure of the utility model a kind of grade of progressive die anti-back material structure;
Fig. 3 be the utility model a kind of grade of progressive die anti-back material structure hold state graph.
Embodiment
As Figure 1-3, a kind of level progressive die anti-back material structure, comprise material strip 1 and anti-discharging device 2, described anti-discharging device 2 is positioned at material strip side 1, and described material strip 1 is provided with breach 3, and described breach 3 is positioned at material strip 1 avris, described anti-discharging device 2 is provided with anti-material returned mouth 4, being provided with stop block 5 and spring 6 in described anti-material returned mouth 4, described spring 6 is connected to below stop block 5, and the traveling direction that described breach 3 is all half trapezoidal setting and go to the bottom direction and material strip 1 with stop block 5 is consistent.
Described stop block 5 is fixedly connected with spring 6, avoids coming off.
Described spring 6 is arranged at anti-material returned mouth 4 internal fixtion, avoids coming off.
The size of described breach 3 is consistent with stop block 5, is convenient to hold.
Described breach 3 is provided with more than one, and each breach 3 is evenly distributed on material strip.
It is trapezoidal that the shape of breach 3 and stop block 5 is not limited only to half, it is possible to is trilateral or other the shape being possible to prevent to fall back.
The beneficial effects of the utility model are: arrange breach on material strip, and coordinate the stop block of a band spring, form the anti-material returned structure of unidirectional restriction of advancing, thus protect mould when not affecting operation.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.
Claims (5)
1. a level progressive die anti-back material structure, it is characterized in that: comprise material strip and anti-discharging device, described anti-discharging device is positioned at material strip side, described material strip is provided with breach, described breach is positioned at material strip avris, and described anti-discharging device is provided with anti-material returned mouth, is provided with stop block and spring in described anti-material returned mouth, described spring is connected to below stop block, and the traveling direction that described breach is all half trapezoidal setting and go to the bottom direction and material strip with stop block is consistent.
