Abstract
A fastening device for pre-buried pipelines relates to the field of aluminum alloy casting tools and comprises a blocking seat provided with a U-shaped chuck on the upper part and a screw rod on the lower part, wherein a cross bar runs through the middle part of the U-shaped chuck, a stop screw is screwed in the top of the U-shaped chuck, the lower end of the screw rod is screwed in the upper end of an adjusting nut, a rolled-thread screw is screwed in the lower end of the adjusting nut, and a locking nut is arranged on the junction of the upper end of the adjusting nut and the screw rod. With the adoption of the fastening device, the rate of finished products is increased, the stress deformation is controlled, namely, a copper pipe can be replaced with a stainless steel pipe, and thus the manufacturing cost is greatly reduced; and the service life of a mould is also prolonged due to the fact that the corrosion resistance of the stainless steel is far higher than that of the copper pipe, thereby the competitiveness of the product is improved.
Description
Technical field:
The present invention relates to aluminium alloy casting frock field, relate in particular to a kind of pre-buried pipeline and use fastener.
Background technology:
The household electrical appliances mould in use; Mould need be with recirculated water to mold heated, and so just requiring will have water back in mould, and the technology of existing placement water back has two kinds; A kind of be the strand moulding after; Process the water pipe groove at the strand inner chamber, then water pipe is put into groove, with low-melting alloy that the tube seat envelope is flat again; The shortcoming of this technology is; The tube seat difficulty of processing is big, and water pipe is placed and limited by cavity shape, and time-consuming, effort, cost are high, so seldom adopt.Another kind is when the strand moulding, and water pipe is embedded in the strand, at first on wooden model, produces the water pipe groove, makes sand mold then, at last water pipe is fixed in the water pipe groove on the sand mold with U sections silk, just can mould assembling cast.What existing casting household electrical appliances mould strand was adopted is the green-sand casting technique, and the pre-buried water pipe material is a copper tube, and the intensity of the sand mold in this technology self is very low; If water pipe is fixed on the sand mold, the stress deformation that water pipe is heated and is produced when casting can make water pipe produce displacement and deformation again; Even be with sand mold to change together; Cause the sand mold avalanche, cause product rejection, even copper tube is like this; More nobody removes to use low, the corrosion resistant stainless steel waterpipe of price again, and reason is that the stress deformation after stainless steel tube is heated is far longer than copper tube; Comprehensive above problem draws, and the strand cost that this explained hereafter is come out is high, yield rate is low; If the stress deformation problem after way control water pipe is heated is arranged; With the qualification rate that improves strand greatly; Low price, corrosion resistant stainless steel waterpipe also can be used as pre-buried pipeline simultaneously, so just can reduce the cost of strand, have also improved the service life of mould.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defective of prior art, provides a kind of pre-buried pipeline simple to operate, broad-spectrum to use fastener, to solve and to control the stress deformation problem after water pipe is heated.
Technical problem to be solved by this invention adopts following technical scheme to realize.
A kind of pre-buried pipeline is used fastener; It is characterized in that: comprise that top is that U type dop bottom is the deck of screw rod; Pass cross bar in the middle of the said U type dop, said U type dop top screws in limit screw, and said screw rod lower end screws in the upper end of adjusting nut; Said adjusting nut lower end has the silk of bundle screw to screw in, and said adjusting nut upper end is provided with locking nut with the screw rod intersection; Said cross bar is a straight-bar, and it is inserted in the U type dop on deck top, is used for load on sandbox, and its length outline is longer than sandbox, is used for being connected on whole fastener and the sandbox; Limit screw is spun in the screw at U type dop top, is used for deck and cross bar is fastenedly connected, and said adjusting nut upper end is connected with the screw rod of deck bottom; Its turn up and down; Can change the length of whole device, thereby realize scalable, the bundle silk screw that said adjusting nut lower end screws in is convenient to fix the connection water pipe with the bundle silk of φ 1mm; And can make between water pipe and the device and form a slit; When casting, liquation can get into this slit, and the water pipe of device below can be wrapped to treat to solidify afterwards by liquation; Said locking nut is spun between the screw rod and adjusting nut of deck bottom, is used for locking adjusting nut, when preventing to prick the silk screw and screwing in adjusting nut, and adjusting nut rotation and influence the length of device.
Said limit screw is vertical with U type dop, and the outside at misalignment U type dop center, so limit screw can very firm fastening cross bar.
Beneficial effect of the present invention is: after 1. this device assembles each other and connects, formed an integral body, the lower end of water pipe and device is fastenedly connected with pricking silk; The top of device is connected with sandbox through cross bar, and the water pipe that makes, device, sandbox have formed integral body, when water pipe when casting is heated; The stress deformation power of its generation has been transferred to sandbox, has avoided the destruction of deformation force to sand mold, and this deformation force is not enough so that this device and sand mold generation deformation and displacement; So this deformation force just can not make water pipe that any change takes place, and has promptly guaranteed the shape and the position of water pipe; Guaranteed the shape of sand mold again, therefore, the yield rate of strand is improved; 2. because the application of this device makes stress deformation be able to control, also just can replace copper tube, because stainless price, makes that manufacturing cost has obtained reducing greatly far below copper tube with stainless steel tube; 3. the utilization of this device can be used as pre-buried pipeline with stainless steel tube, and stainless corrosion resistance is far above copper tube, thus improved the service life of mould, thus improved Enterprises'Competitiveness.
