Abstract
The utility model discloses a kind of perforating die of fixed stripper structure, its structure comprises die shoe and upper bolster, be flexibly connected by the guide pillar of both sides between die shoe and upper bolster, punch holder is provided with below upper bolster, die is provided with by bolt above die shoe, stripper has been bolted at die upper surface, the gap for placing flitch is left between stripper first half and die upper surface, the padded bloom of more than one piece is movably equipped with between above the below of stripper latter half and die, upper bolster central movable runs through and is provided with die shank, two punch are connected with bottom die shank, stripper is provided with two position punchs for punch motion, the height adjustable in the gap being used for placing flitch of stripper first half of the present utility model and die upper surface, when this makes the excesssive gap that avoids between stripper and die and causes discharging, punch easily occurs damaged or gap is too small and cause flitch to occur the distortion such as warpage because rocking.
Description
Technical field
The utility model relates to perforating die, particularly relates to a kind of perforating die of fixed stripper structure.
Background technology
Modern Mold industry is technology, the industry of intensive capital, the height of Tool and Die Technology level, decide the quality of product to a large extent, the development ability of benefit and new product, therefore the important symbol of a measurement national product manufacture level height has been become, for the punching processing product that required precision is not high, the good fixed stripper structure of frequent employing workability, but the perforating die of the fixed stripper structure of prior art, if the excesssive gap between stripper and die, although material loads mould can become easy, but during discharging easily there is breakage because rocking in punch, gap is smaller relatively good, due to when carrying out hole machined without material pressing device, therefore easily there is the distortion such as warpage, so the height in gap between stripper and die is extremely important, the height in the gap between the perforating die stripper of the fixed stripper structure of prior art and die, this makes to produce and is subject to very large restriction.
Utility model content
For the problems referred to above, the utility model provides a kind of perforating die of fixed stripper structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the perforating die providing a kind of fixed stripper structure, its structure comprises die shoe and upper bolster, be flexibly connected by the guide pillar of both sides between described die shoe and upper bolster, punch holder is provided with below described upper bolster, die is provided with by bolt above described die shoe, stripper has been bolted at described die upper surface, the gap for placing flitch is left between described stripper first half and die upper surface, the padded bloom of more than one piece is movably equipped with between above the below of described stripper latter half and die, described upper bolster central movable runs through and is provided with die shank, two punch are connected with bottom described die shank, described stripper is provided with two position punchs for punch motion.
Further, described guide pillar and be provided with guide pin bushing between die shoe and upper bolster.
Further, the height of described stripper first half is 1/2nd of latter half height.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
1. when the end machining hole for long size product, adopt fixed stripper to construct, operation can be more convenient, can load among stripper by material, and namely withstand stripper latter half or padded bloom is processed withstanding inner side, therefore workability is better.
2. due between the activity of padded bloom is installed in above the below of stripper latter half and die, this makes the height adjustable in the gap being used for placing flitch of stripper first half and die upper surface, and when this makes the excesssive gap that avoids between stripper and die and causes discharging, punch easily occurs damaged or gap is too small and cause flitch to occur the distortion such as warpage because rocking.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the overall structure schematic diagram of the perforating die of a kind of fixed stripper structure of the utility model;
Fig. 2 is stripper of the present utility model and padded bloom johning knot composition;
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
By reference to Fig. 1 and Fig. 2, a kind of perforating die of fixed stripper structure, its structure comprises die shoe 1 and upper bolster 2, guide pillar 4 by both sides between described die shoe 1 and upper bolster 2 is flexibly connected, punch holder 6 is provided with below described upper bolster 2, die 3 is provided with by bolt above described die shoe 1, stripper 5 has been bolted at described die 3 upper surface, the gap for placing flitch is left between described stripper 5 first half and die 3 upper surface, the padded bloom 9 of more than one piece is movably equipped with between above the below of described stripper 5 latter half and die 3, described upper bolster 2 central movable runs through and is provided with die shank 7, two punch 8 are connected with bottom described die shank 7, described stripper 5 is provided with two position punchs moved for punch 8, described guide pillar 4 and be provided with guide pin bushing 10 between die shoe 1 and upper bolster 2, the height of described stripper 5 first half is 1/2nd of latter half height.
When the specification of flitch 11 determines, can according to the thickness of flitch 11 regulate stripper 5 first half and die 3 upper surface gap namely pass through to use the block number of padded bloom 9, in time starting working, die shank 7 connects power source, the control that power source moves up and down to die shank 7, makes punch 8 toward position punch fast movement, namely allows flitch 11 punching, take punching success to and just can change flitch 11.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
