Abstract
The present invention relates to sealing strips for lift car hall doors and the shaping process of the sealing strips, which comprises hard-flexible modification PVC layers which are arranged on two car hall doors, wherein the PVC layers are mutually matched and inner parts of the PVC layers are embedded with skeletons. Each skeleton is a stainless steel sheet or a cold-rolled steel sheet which is rolled to be shaped. One end of each of the mutually matched hard modification PVC layers is embedded with a flexible modification PVC layer, and two mutually matched flexible modification PVC layers are provided with an inosculated contact surface. The shaping process of the present invention has the skeleton shaping steps that an SUS430 type steel band or an SPCC type cold-rolled steel band is cut into strips and the strips are rolled and shaped into skeleton blanks. The present invention has the mixing granulation steps that according to weight percentage, 60% to 85% of polyvinyl chloride resin, 10% to 30% of plasticizing agent and 5% to 10% of auxiliary materials are mixed in proportion, respectively carried out hard PVC modification and flexible PVC modification and are implemented with extrusion shaping steps with the skeleton blanks. The skeleton blanks are embedded and fixed in the hard modification PVC layers, and the mutually matched ends are embedded with flexible modification PVC and are extruded and shaped.
Description
Technical field
The present invention relates to sealing band and forming process, particularly be applied to the Lift Car Door Hall Door Sealing Strip And Shaping Process of elevator.
Background technology
Elevator, staircase market competition are fierce day by day at present, and product is brought in constant renewal in.Each big elevator company simplifies approximately at the prerequisite next part of ensuring the quality of products, and the sealing band that elevator is used is constantly replaced improvement.The sealing band that elevator is used plays crashproof, sealing, shading, decoration function nothing but on its function.In the prior art, the exploitation of door-window sealing band early, as the applying date is the Chinese utility model patent ZL86201189 on February 28th, 1986 " clamping type sealing band once-through method apparatus for continous formation ", it discloses a kind of rubber semi-finished product that has soft core of sebific duct and steel sheet skeleton of producing, the semi-finished once-through method apparatus for continous formation of clamping type sealing band particularly. this device just can realize that because of only needing on the rubber extruder special head of preparation and having the core pattern and the shape of the mouth as one speaks of suitable shape once-through method is continuously shaped.Also be the Chinese utility model patent ZL03269958.1 on September 23rd, 2003 " the door-window sealing band that vinyl coating is arranged " just like the applying date, it discloses a kind of door-window sealing band that vinyl coating is arranged, the U type door and window rubber strip that comprises embedded steel frame, its inwall has jaw, the sidepiece one of U type door and window rubber strip connects sponge bubble sealing member, the coating that the outside face of U type door and window rubber strip has the ethene coat film that is extruded to shape to one to constitute.But above-mentioned technology can't be applied to lift car gate sealing band, and lift car gate sealing band originally all adopted aluminum alloy bar to scurry soft rubber-plastic strip installation again and forms; Have cost height, easy shortcoming such as come off.
Summary of the invention
Technical matters to be solved by this invention is at above-mentioned defective, and provide Lift Car Door Hall Door Sealing Strip And Shaping Process, corrosion-resistant steel or cold-rolled steel skeleton bag are moulded firmly by adopting, the soft gasket of moulding the technology making, the needs of elevator functions can be satisfied, cost-cutting, good and cheap purpose can be reached again.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
Lift cage sealing strip, comprise and be installed in the hard soft modified PVC layer that is embedded with skeleton that matches on the elevator two fan car gate Room doors, the technical measures of taking comprise: skeleton is the stainless steel substrates or the cold rolling steel disc of flow forming, be positioned at hard modified PVC layer one end and be embedded with soft modified PVC layer, and two soft modified PVC layers that match have the contact surface that matches.
For optimizing technique scheme, the concrete measure of taking also comprises:
For saving cost, to gain in strength, skeleton is SUS430 steel band of model or the cold rolling steel disc of SPCC type, for adapting to the needs of various lift cage doors, its vertical sectional shape is L shaped or U-shaped or ∑ shape or ∏ shape or Γ shape or soup ladle shape.
, sealing crashproof, shading, two contact surfaces of decoration function for playing for the inclined-plane that pastes mutually or be meshed be spaced dentation.
Same reason, two contact surfaces are respectively concave surface and the convex surface that pastes mutually.
Two contact surfaces are respectively L face that fits and the face of falling L.
Same reason, the skeleton cross section is flat U-shaped, the hard modified PVC layer other end of this flat U-shaped also is embedded with soft modified PVC layer.
The forming process of lift cage sealing strip comprises skeleton forming step and mixing granulation step, and the technical measures of taking comprise: the skeleton forming step is for to cut open bar and flow forming skeleton base sheet with SUS430 steel band of model or SPCC type cold-rolled strip; The mixing granulation step is for by weight percentage, 60%～85% Vinyl chloride resin, plasticizer 10%～30%, auxiliary material 5%～10% ratio are mixed, carry out hard PVC modification and flexible PVC modification respectively, and with skeleton base sheet enforcement extrusion molding step, skeleton base sheet is mounted in the hard modified PVC layer, the end that will match simultaneously is embedded with soft modified PVC, extrusion molding; And order enters cooling and draws and get step, fixed length sawing step, the die-cut step of fixed length, location punching step.
Compared with prior art, the present invention is the stainless steel substrates or the cold rolling steel disc of flow forming by adopting skeleton, be positioned at hard modified PVC layer one end and be embedded with soft modified PVC layer, and two soft modified PVC layers that match has the contact surface that matches.The lift cage sealing strip that SUS430 type corrosion-resistant steel and the cold rolling ladle of SPCC type be soft, mould firmly not only can satisfy functional requirement from structure, and elegant in appearance, simple in structure, saves aluminium, and is easy for installation, good and cheap.
