Abstract
The utility model relates to the field of temperature controllers, in particular to a pair of seal cutting pincers special for a capillary tube of a temperature controller. The seal cutting pincers comprise a left pincers body and a right pincers body. The left pincers body and the right pincers body are hinged in a crossed mode, a first blade is arranged on the inner surface of a front end pincers port portion of the left pincers body, a second blade is arranged on the inner surface of a front end pincers port portion of the right pincers body, and the first blade and the second blade are jointed to form a pincers port closing line. The upper portions of cross sections of blade portions of the first blade and the second blade are in upward protruding semi-circular-arc shapes or semi-oval arc shapes. The thickness of the blade portion of the first blade and the thickness of the blade portion of the second blade range from 1.5 millimeters to 2 millimeters. When the pincers port portion of the left pincers body and the pincers port portion of the right pincers body are closed, the first blade and the second blade squeezes the capillary tube of the temperature controller by utilizing semi-arc faces to enable the capillary tube of the temperature controller to deform and be sealed, then, workers can continue to apply pressure and the capillary tube of the temperature controller can be cut off. The rigidity of a copper pipe is lower than that of the pincers blades and the pipe wall of the copper pipe is thin and can be cut off easily, sealing and cutting operations can be completed at a time.
Description
Technical field
The utility model relates to temperature controller field, especially relates to a kind of temperature controller capillary special-purpose sealing combination pliers.
Background technology
Compression-type temperature controller is by filling thermometer bulb and the capillary of temperature-sensitive working medium in airtight, being the variation of space pressure or volume by the change transitions of controlling temperature, while reaching desired temperature, by flexible member and fast wink actuation mechanism, automatically close contact, to reach the object of A.T.C.Its capillary is hermetically-sealed construction, inside fills temperature-sensitive working medium.Temperature-sensitive working medium adopts R12 conventionally, also has at present the environmental protection gases such as employing propane (R290), so sealing capillaceous is one of key point of temperature controller quality.
At present, Sealing pliers cutting edge for capillary sealing mostly is plane cutting edge, snap-in force by pincers palate and pincers lower jaw closure is flattened sealing to temperature controller capillary (copper pipe), but its sealing effect is bad, temperature controller capillary is in deformation process, because capillary wall is very thin, when sealing, the vertical side edge of its plane cutting edge is too sharp-pointed for capillary, careless slightly just easily capillary is cut or extruding is broken, when application, there will be the situation of coolant leakage, cause using temperature controller normally to move.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provides a kind of temperature controller capillary special-purpose sealing combination pliers, disposablely complete sealing capillaceous and cut off operation, by to solve the easy of existing capillary Sealing pliers, capillary being pushed to the technical problem of breaking, improved operating efficiency simultaneously.
The technical scheme that the utility model adopts is: temperature controller capillary special-purpose sealing combination pliers, comprises left caliper and right caliper body; Described left caliper and right caliper body cross-articulation, the front end nip part inner surface of described left caliper is provided with the first sword, and described right caliper body front end nip part inner surface is provided with the second sword, and described the first sword engages with the second sword and forms jaw closed line; The top, blade cross section of described the first sword and the second sword is semicircular arc or the semiellipse arc raising up.In the time that the nip part of left caliper and right caliper body is closed, the first sword and the second sword utilize half cambered surface extruding temperature controller capillary to make it distortion sealing thereupon, then workman continues to exert pressure, (hardness of copper pipe is very thin lower than pincers cutting edge and tube wall can to cut off temperature controller capillary, be easier to cut off), once complete sealing and cut off operation.
Further, the blade thickness of described the first sword and the second sword is 1.5 mm-2mm.Blade thickness is narrow, and (sealing effect is poor to be less than 1.5 mm, and leak rate is high, and blade thickness excessive (being greater than 2mm), although sealing effect is better, needs with larger strength operation, and long-time fatiguability, reduces efficiency on the contrary.
Further, described the first sword and the second sword root are provided with trapezoidal key, and the nip part inner surface of described left caliper and right caliper body has corresponding keyway, and described the first sword and the second sword are arranged on the nip part of described left caliper and right caliper body by keyway fit system.
Beneficial effect: this product operation is convenient, effectively stable, gas leakage obviously declines, and efficiency is significantly improved.
Accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of the utility model jaw.
In figure: 1. right caliper body, 2. left caliper, 3. the second sword, 4. the first sword, 5. keyway.
The specific embodiment
Referring to Fig. 1, temperature controller capillary special-purpose sealing combination pliers, comprises left caliper 2 and right caliper body 1; Left caliper 2 and right caliper body 1 cross-articulation, the front end nip part inner surface of left caliper 2 is provided with the first sword 4, and right caliper body 1 front end nip part inner surface is provided with the second sword 3, the first swords 4 and engages formation jaw closed line with the second sword 3; The top, blade cross section of the first sword 4 and the second sword 3 is semicircular arc or the semiellipse arc raising up.
The first sword 4 and the second sword 3 all adopt general tool steel to make, and its blade thickness is 1.5 mm-2mm.Blade thickness is narrow, and (sealing effect is poor to be less than 1.5 mm, and leak rate is high, and blade thickness excessive (being greater than 2mm), although sealing effect is better, needs with larger strength operation, and long-time fatiguability, reduces efficiency on the contrary.
The first sword 4 and the second sword 3 can be affixed by welding or solid forging mode and left caliper 2 and right caliper body 1, optimal way as shown in the figure, the first sword 4 and the second sword 3 roots are equipped with trapezoidal key, the nip part inner surface of left caliper 2 and right caliper body 1 has corresponding trapezoidal keyway, and the first sword 4 and the second sword 3 are arranged on the nip part of left caliper 2 and right caliper body 1 by keyway fit system.When the cutting edge of the first sword 4 and the second sword 3 may wear to a certain degree, can change easily.
In the time that the nip part of left caliper 2 and right caliper body 1 is closed, the first sword 4 and the second sword 3 utilize half cambered surface extruding temperature controller capillary to make it distortion sealing thereupon, then workman continues to exert pressure, (hardness of copper pipe is very thin lower than pincers cutting edge and tube wall can to cut off temperature controller capillary, be easier to cut off), once complete sealing and cut off operation.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
