Abstract
The invention provides polytetrafluoroethylene membrane pre-pressing equipment. The equipment comprises a hydraulic station and an oil cylinder frame, an up-pressing oil cylinder and a down-pressing oil cylinder are arranged on the oil cylinder frame, the hydraulic station is connected to the up-pressing oil cylinder and the down-pressing oil cylinder, and a blank mould is arranged between the up-pressing oil cylinder and the down-pressing oil cylinder. Through a composition improvement, the problem that a polytetrafluoroethylene pre-pressed blank is non-uniform during the membrane production process is effectively solved. The produced blank has the advantages of uniform texture, even density, high brightness, and proper strength, and thus the uniformity of post blank wideness and blank belt is guaranteed.
Description
Technical field
The present invention relates to a kind of equipment used in polytetrafluoroethylene (PTFE) film-forming process, specifically a kind of pre-press equipment used in polytetrafluoroethylene (PTFE) film-forming process.
Background technology
The legacy equipment used in polytetrafluoroethylene (PTFE) film-forming process, project organization is unreasonable, be difficult to manipulation, produce in the process of poly tetrafluoroethylene simultaneously and be difficult to ensure that film embryo thickness all claims, density equalization, often there are faulty materials, the end product quality of poly tetrafluoroethylene and output are greatly affected.
Summary of the invention
The shortcoming existed for prior art and deficiency, technical problem to be solved by this invention is, provides a kind of pre-press equipment of poly tetrafluoroethylene, is improved by structure, effectively solves the Density inhomogeneity sex chromosome mosaicism of the pre-stamped embryo in polytetrafluoroethylene (PTFE) film-forming process.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of pre-press equipment of poly tetrafluoroethylene is provided, it comprises Hydraulic Station and oil cylinder framework, oil cylinder framework is arranged compressing cylinder and down pressing oil cylinder, Hydraulic Station connects compressing cylinder and down pressing oil cylinder respectively, arranges embryo mould processed between upper compressing cylinder and down pressing oil cylinder.
The pre-press equipment of above-mentioned poly tetrafluoroethylene, on it, compressing cylinder is arranged on the top of oil cylinder framework, installs pressure pilot pin below upper compressing cylinder.
The pre-press equipment of above-mentioned poly tetrafluoroethylene, its down pressing oil cylinder is arranged on the bottom of oil cylinder framework, installs and press down pilot pin above down pressing oil cylinder.
The pre-press equipment of above-mentioned poly tetrafluoroethylene, on it, compressing cylinder and down pressing oil cylinder slide up and down along oil cylinder framework respectively and extrude embryo dies cavity processed.
Tool of the present invention has the following advantages and Advantageous Effects:
1, the pre-press equipment of poly tetrafluoroethylene of the present invention, effectively solves the Density inhomogeneity sex chromosome mosaicism of the pre-stamped embryo in polytetrafluoroethylene (PTFE) film-forming process.
2, the film embryo thickness that the pre-press equipment of poly tetrafluoroethylene of the present invention is produced all claims, density equalization, colourity light, and tough and tensile suitable, to the width of subsequent film embryo, all titles of flesh band are until most important effect.
3, the pre-press equipment of poly tetrafluoroethylene of the present invention saves time than traditional equipment, energy-conservation, even, density is high, improves the germ extraction rate of 40% than other equipment.
