Description

Boiling range cryostat pipe curves U-tube clamping fixture for correcting
Technical field
The utility model relates to a kind of U-tube clamping fixture for correcting, and particularly a kind of boiling range cryostat pipe curves U-tube clamping fixture for correcting.
Background technology
According to national standard, the copper pipe in cryostat is the curved tube curving continuously smooth.The average gradient of every millimeter of PIPE SYPHON curved tube is 0.26 m m (being equivalent to sinusoidal 15 ° of angles).Every millimeter of gradient of leaching people part should be not less than 0.24 mm, also should not be greater than 0.28 mm.Lower end extension is slightly to the rear to be bent downwardly, and its length is 76 mm.Bend so U-shaped bend pipe to compare be not easy when there is no mould, and poor repeatability, waste time and energy.
Summary of the invention
Technical problem to be solved in the utility model is the problem overcoming the U-shaped swan neck system effort of the existing making existed in background technology and poor repeatability, and provide a kind of boiling range cryostat pipe to curve U-tube clamping fixture for correcting, this boiling range cryostat pipe curves U-tube clamping fixture for correcting, mould can be utilized to bend meet the boiling range cryostat U-tube of GB, simply, fast, reproducible.
The invention for solving the technical problem reaches by following technical scheme: this boiling range cryostat pipe curves U-tube clamping fixture for correcting, comprise fixed handle, Correction Die, described fixed handle bottom is fixedly connected with 4 alignment pins, described Correction Die is a casing, Correction Die upper surface center has rectangular channel, and rectangular channel both sides have 2 locating holes, and described locating hole is corresponding with the alignment pin of fixed handle bottom; Before and after Correction Die, two sides are equipped with left side regulating handle installing hole and right side regulating handle installing hole respectively, have low side regulating handle installing hole bottom Correction Die, described left side regulating handle installing hole, right side regulating handle installing hole, low side regulating handle installing hole are built with handle; Described low side regulating handle installing hole is on left side regulating handle installing hole, the vertical center line of right side regulating handle installing hole.
The utility model can have following beneficial effect compared with above-mentioned background technology: this boiling range cryostat pipe curves U-tube clamping fixture for correcting owing to adopting said structure, utilize mould to bend to meet the boiling range cryostat U-tube of GB, simple, quick, reproducible, time saving and energy saving, efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in accompanying drawing 1 and Fig. 2, Fig. 3, this boiling range cryostat pipe curves U-tube clamping fixture for correcting and comprises fixed handle 2, Correction Die 1, described fixed handle 2 comprises a base plate 13 and top 4 side plates 7 all around, wherein 2 side plates 7 in left and right are connected to base plate 13 two ends place, 2 side plates 7 in front and back are connected in the middle part of base plate 13, and the base plate 13 outside the side plate of 2, front and back opens 2 holes, hole internal fixtion alignment pin 8; Described Correction Die 1 is a casing, and Correction Die 1 upper surface center has rectangular channel 11, and rectangular channel 11 both sides have 2 locating holes 12, and described locating hole 12 is corresponding with the alignment pin 8 of fixed handle 2 bottom; Before and after Correction Die 1, two sides are equipped with left side regulating handle installing hole 4 and right side regulating handle installing hole 5 respectively, have low side regulating handle installing hole 6 bottom Correction Die 1, described left side regulating handle installing hole 4, right side regulating handle installing hole 5, low side regulating handle installing hole 6 are built with handle; Described low side regulating handle installing hole 6 is on left side regulating handle installing hole 4, the vertical center line of right side regulating handle installing hole 5; Have rectangular opening immediately below described Correction Die 1, rectangular opening is built-in with arc 9, coincide, and be fixed on Correction Die 1 base plate by bolt 10 bottom arc 9 and the U-tube of bottom.As shown in Figure 4, described fixed handle about 22 side plates have some fixing holes; By the fixed head on fixing hole, U-tube is fixed on fixed handle 2.
When this boiling range cryostat pipe curves the use of U-tube clamping fixture for correcting, first look for satisfactory pipe, be cut into 76mm, utilize pulley to curve a little arc, remainder is curved a large arc and makes U-tube by recycling cylinder; U pipe is placed on Correction Die 1 li by the rectangular channel at Correction Die 1 center, fixed handle 2 is loaded onto on top, by regulating left side regulating handle installing hole 4, right side regulating handle installing hole 5, low side regulating handle installing hole 6 built with the curvature of handle adjustment U line pipe, Correction Die is graduated, as long as the left and right of U-tube and bottom to be transferred to the curvature that corresponding scale just can be up to state standards; Then with two pieces of fixed heads, U-tube is fixed on fixed handle, ensures that U-tube is indeformable.Then mention fixed handle, be placed in casting die, fixed handle and casting die have alignment pin.Start casting, namely cooling forming can be made into the cryostat pipe meeting GB.
