Abstract
Foam plastics gap former structure of the present invention, drives cam rotation by driving means so that the flange jacking pad of cam so that the depression bar being provided with pad is the most vertically slidable.Have passed through the slotted eye on depression bar due to the rotating shaft of cam, therefore, in depression bar moves up and down, will not interfere with cam.Furthermore, a drift being set owing to sliding at lower straight intracavity, when depression bar moves downward, relies on the action of gravity of self, bottom impacts on drift so that drift departs from from lower straight intracavity under the effect of depression bar, squeezes in the foam plastics of lower section, forms gap.In following process, it will be permanently formed gap at foam plastics, reach processing and the requirement used.
Description
Technical field
The present invention relates to a kind of plastic processing device, be specifically related to a kind of foam plastics gap former structure.
Background technology
Foamed plastic, foaming.Foaming is the process making plastics produce microcellular structure.Almost all of thermosetting and thermoplastic can make foam plastics, and conventional resin has polystyrene, polyurethane, polrvinyl chloride, polyethylene, ureaformaldehyde, phenolic aldehyde etc..Foamed plastic has the less resin of monomer volume internal consumption, low thermal conductivity, the mechanical performance of improvement and sound insulation value, adds the advantages such as bending Zhang Du.It is widely used among every field.In foamed plastic, there are many holes, but these holes are the most irregular, when needing well-regulated gap in production and processing, it is difficult to directly obtain, need to carry out secondary operations.
Summary of the invention
It is an object of the invention to provide a kind of foam plastics gap former structure, use easy structure to design, it is possible to reach the purpose of production and processing.
For reaching above-mentioned purpose, the technical scheme is that foam plastics gap former structure, including base, described base is provided with a vertical cavity, described cavity includes the lower straight chamber set gradually from bottom to up, circular cavity and upper straight chamber, and described lower straight intracavity slides and is provided with a drift, described circular cavity and upper straight intracavity are provided with a depression bar, and the middle part of described depression bar is provided with a pad；Being provided with a cam in described circular cavity, the flange of described cam contacts with pad, and the lower section that described depression bar stage casing is positioned at pad offers slotted eye, and the rotating shaft of described cam passes slotted eye.
When using technique scheme, drive cam rotation by driving means so that the flange jacking pad of cam so that the depression bar being provided with pad is the most vertically slidable.Have passed through the slotted eye on depression bar due to the rotating shaft of cam, therefore, in depression bar moves up and down, will not interfere with cam.Furthermore, a drift being set owing to sliding at lower straight intracavity, when depression bar moves downward, relies on the action of gravity of self, bottom impacts on drift so that drift departs from from lower straight intracavity under the effect of depression bar, squeezes in the foam plastics of lower section, forms gap.In following process, it will be permanently formed gap at foam plastics, reach processing and the requirement used.
Further, the top in described straight chamber is provided with chute, and the top of described depression bar is provided with slide bar, and described slide bar inserts in chute, and described slide bar is arranged with stage clip.This setting can increase the depression bar active force to drift by stage clip, so can alleviate the weight of depression bar, saves material.
Further, described pad is hinged with the Hp contacts of roller, described roller and cam.Sliding friction can be become rolling friction by roller by this setting, reduces and damages.
Further, the lower section described base being positioned at drift is provided with punch holder.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of foam plastics gap former structure embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, foam plastics gap former structure of the present invention, including base 1, base 1 is provided with a vertical cavity, described cavity includes the lower straight chamber 2 set gradually from bottom to up, circular cavity 3 and upper straight chamber 4, slide in lower straight chamber 2 and be provided with a drift 5, and the lower section that base is positioned at drift is provided with punch holder.Being provided with a depression bar 6 in circular cavity 3 and upper straight chamber 4, the middle part of depression bar 6 is provided with a pad；It is hinged with roller 61 on pad, in circular cavity 3, is provided with a cam 7, roller 61 and the Hp contacts of cam 7.Sliding friction can be become rolling friction by roller 61 by this setting, reduces and damages.The stage casing of depression bar 6 is positioned at the lower section of pad and offers slotted eye, and the rotating shaft of cam 7 passes slotted eye.The top in upper straight chamber 4 is provided with chute, and the top of depression bar 6 is provided with slide bar, and slide bar inserts in chute, and slide bar is arranged with stage clip 8.This setting can increase the depression bar 6 active force to drift 5 by stage clip 8, so can alleviate the weight of depression bar 6, saves material.
In the present invention, cam 7 is driven to rotate by driving means so that the flange jacking pad of cam 7 so that the depression bar 6 being provided with pad is the most vertically slidable.Owing to the rotating shaft of cam 7 have passed through the slotted eye on depression bar 6, therefore, in depression bar 6 moves up and down, will not interfere with cam 7.Furthermore, owing to sliding in lower straight chamber 2, a drift 5 is set, when depression bar 6 moves downward, relying on self gravity and the effect of stage clip 8, bottom impacts on drift 5 so that drift 5 departs under the effect of depression bar 6 in lower straight chamber 2, squeeze in the foam plastics of lower section, form gap.In following process, it will be permanently formed gap at foam plastics, reach processing and the requirement used.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some deformation and improvement can also be made; these also should be considered as protection scope of the present invention, and these are all without affecting effect and the practical applicability that the present invention implements.
