Description
Technical field
The present invention relates in general to and a kind ofly is used for the press fit part so that the equipment of connecting pipe section, and more especially the present invention relates to be used to push the equipment of this assembly parts.
Background technology
Compression fittings normally contains the tubular sleeve of steel.Assembly parts compress diametrically so that the jointed pipe end.Compression fittings forms the joint of anti-leak between pipe end.Joint has significant mechanical strength, and oneself supports.For compression fittings, use compression tool.
Compression tool generally includes the pressurizing tool that contains the hydraulic cylinder that has piston, and is used for motion with piston and converts to and be applied on the pressurization assembly parts so that assembly parts are pressed in the equipment on the connected pipe sections.For some pipe diameter, press jaw is connected on the pressurizing tool, and press jaw is placed near the assembly parts that will be extruded.For this configuration, the hydraulic piston in the pressurizing tool will be usually included in plunger actuation so that the roller that rolls along linear path during contact press jaw arm.When instrument was activated, piston will be along the linear path fixing distance of moving, so that with the recline mode extrusion piston of arm of its roller.The end of the mode engaging claw that roller engages with line, and make its pivot and extruding be arranged in compression fittings between the pawl.The example of the pressurizing tool that comprises press jaw is provided in Fig. 1 and 2.
For some line size (normally bigger size), the use of pressurizing tool is restricted, and this is because it is difficult to and formation motion and enough big so that center on the pawl that the pressurization assembly parts are installed easily inexpediently usually.In this application, pressure rings or press slings are commonly used to help extrusion operation.In this case, pressure rings is placed near the assembly parts that will be extruded, and the pressure rings actuator is connected on the pressurizing tool.The pressure rings actuator is similar to press jaw, and wherein it comprises pivotal arm, but pressure rings actuator and pressure rings interface, thus cause the tool drives of the pawl pivot commentaries on classics of pressure rings actuator to apply force on the pressure rings, so that the pressurization assembly parts.
Usually, compression tool is designed so that each driving of instrument causes hydraulic piston to move along the fixed range path.The linear range of piston motion is commonly referred to as " stroke " of instrument for given instrument.The power output of piston along stroke motion the time will be depended on size, geometry and other performance of hydraulic cylinder and piston.The product of the piston operating range when usually, the maximum of compression tool " merit " output that can provide in the single stroke of piston will be with output of the power of instrument and tool drives is corresponding.For example, the typical maximum work output that comes from the instrument that power that 32kN can be provided and piston stroke be 40mm will be 1.280kN-m.In fact, because the restriction of intrinsic system, gap and the combined error between for example a plurality of parts and make the operating condition that pawl is opened and the roller withdrawal is required, this can be 1.5mm level waste stroke else, can not utilize 100% theoretical maximum merit output.
If same instrument is intended for use to push small pipeline (wherein using extruding pawl and little pressure rings) and is intended for use than large pipeline size (wherein can use big extrusion ring), the restriction of the maximum work of given compression tool output can form challenge.Use for some, the maximum work output of instrument is not enough to provide pushes the quantity that all press-fit the required merit of accessory (the desirable effect of tool using) fully.Therefore, use the people of big or little press fittings must carry and keep little pressurizing tool (being used for little assembly parts) and big pressurizing tool, big pressurizing tool is used for press-fiting greatly the occasion of often not using (merit output that need be bigger than small tool gained) of accessory.The needs of this multiple pressurizing tool cause increase and other unwanted results of cost, maintenance, device requirement.Though some system uses single suspension ring and a plurality of actuator (pawl) that two step extrusion operations are provided, the demand of a plurality of actuators relates to the use or the transportation of remarkable interpolation weight, and need from instrument, remove initial actuator, and in extrusion process, replace second actuator, cause complicated operation, loaded down with trivial details, relatively slowly and easily make mistakes.
The present invention is directed to a kind of equipment, when the merit that the required merit of pressurization assembly parts is produced greater than the pressurizing tool single actuation, this equipment makes effectively and easily press fit part of pressurizing tool.
Summary of the invention
The present invention is directed to a kind of equipment, when the merit that the required merit of pressurization assembly parts is produced greater than the pressurizing tool single actuation or when the needs multistep is pushed suddenly, this equipment makes easily and easily press fit part of pressurizing tool assembly.

According to further instruction of the present invention, carry out extrusion operation, wherein be broken into two or more separation steps in the extrusion process, thereby thereby comprising pressurizeing keeps pressurization to remain on assembly parts on the pipeline that applies assembly parts and at least once pressurizes so that the pressurization crimping provides at least one step of suitable sealing so that provide.Figure 15 A and 15B explanation are specially adapted to the pressure rings assembly 150 that multistep is pushed form suddenly.
With reference to figure 15A and 15B, the pressure rings component table is shown as and comprises and form a plurality of pressure rings sections link together so that pivot around common point 154 six roughly semicircular part section 152A-1,152A-2,152B-1,152B-2,152C-1 and 152C-2.Each semicircular part paragraph qualification is configured as the sack at the tip that receives a pair of actuator arm.Ring assemblies 150 is shaped and is designed in use that ring assemblies will be placed on the pressurized assembly parts.When so locating, section 152A-1 of portion and 152A-2 will be positioned on the part of assembly parts, so that will initially keep pressurization to offer and will be connected on one of duct element by assembly parts; Section 152B-1 of portion and 152B-2 will be positioned to the zone of assembly parts of pressurizeing, thereby the sealing pressurization of seal bead is provided; And the section 152C-1 of portion is positioned to and will keeps pressurization to offer another duct element that is connected by assembly parts with 152C-2.After ring assemblies is located around assembly parts, the tip of a pair of actuator jaws will be positioned in the sack that limits by section 152A-1 of portion and 152A-2, and the instrument that is connected with pawl is activated, and therefore formation is fixed on described assembly parts the maintenance on one of connected duct element is pressurizeed.Instrument will then move, and make the tip of actuator arm be positioned in the sack that limits by parts 152B-1 and 152B-2, and instrument will be actuated to provide the seal bead pressurization.At last, the tip of actuator jaws will move to the sack that limits by section 152C-1 of portion and 152C-2, and drive for the third time, provide second to keep pressurization.
The pressure rings assembly 150 that should be noted that Figure 15 A and 15B is intended for use following pressurization assembly parts, and these pressurization assembly parts have in the zone of the maintenance on the both sides of assembly parts pressurization and are positioned at crimp regions between two zones that are used to keep pressurizeing.It is further to be understood that other semicircle encircles section in pairs and can axially add, so that be applicable to other assembly parts structure that needs a plurality of maintenance pressurizations and allow the crimping position of the rapid crimping of multistep.Same some assembly parts need the paired configuration of this semicircle.For example, the seal bead that assembly parts can need maintenance pressurization side by side and be positioned at the axial end portion place of assembly parts, for example assembly parts that obtain from Mapress or Yorkshire.
In described example, be used for adding of seal bead to be pressed in first and to keep pressurization to carry out after finishing.Should be understood that described process is exemplary, and can adopt other process.For example, in the process that it is contemplated that, seal bead pressurization is at first carried out, and keeps pressurization to carry out at last, and perhaps two keep pressurization at first to finish, and seal bead is carried out when pressurizeing in the end extrusion operation.
Figure 16 explanation is similar to the pressure rings assembly 160 in conjunction with Figure 15 A and 15B description.But, in this structure, outer segments 162A-1,162A-2,162C-1 and the 162C-2 of ring section are designed to have notch part section 164,165 and the unshowned corresponding notch part section of Figure 16, this corresponding notch part section be positioned at that the section 162A-2 of portion and 162C-2 go up and with intermediate section 162B-1 and 162B-2 interface, with guarantee central pressurized operation (seal bead pressurization) at first (promptly on order) carry out. Breach 164 and 165 configuration make used outer segments to provide any of pressurization to attempt and will cause invalid pressurization to (162A-1 and 162B-2 or 162C-1 and 162C-2) before by the central portion section 162B-1 and 162B-2 pressurization being finished, this pressurization for the user of ring assemblies or instrument obviously as seen so that the indication of invalid pressurization is provided for the user.Invalid pressurization is guaranteed by the following fact, be that breach 164 and 165 (and the corresponding breach on the ring downside) is designed so that the driving of the outer segments before intermediate section drives will cause outer segments to engage with intermediate section, and the pressurization of the outer segments before therefore the inner segments pressurization is finished will cause actuator tool to attempt to carry out two extrusion operations.Because in the application of using ring assemblies 160, the output of the merit of instrument is not enough to carry out two pressurized operations, the pressurized operation of being attempted is with invalid.If at first carry out the centre pressurization, because the distortion of pressurization assembly parts in this zone, it is closed or partly closed that intermediate section 162B-1 and 162B-2 will be tending towards.Therefore, outer segments will not cause the joint of inner segments or " the two pressurization " attempted operation with rear drive.Therefore, ring assemblies 160 provides a kind of structure, and this structure is tending towards guaranteeing that order is carried out central authorities' pressurization before finishing external pressurized.
Be similar to Figure 15 A and 15B, can be axially in conjunction with other pressure rings assembly.Equally, the seal bead and the profile that keeps pressurizeing are reconfigurable in the configuration that encircles on the interior diameter, are somebody's turn to do an assembly parts structure special use of ring pressurization as hope.
Figure 17 A and 17B explanation are similar in conjunction with Figure 15 A, 15B and the 16 pressure rings assemblies of describing.But the structure of Figure 17 A and 17B is designed to guarantee external pressurized operation (the section 172A-1 of use portion, 172A-2,172C-1 and 172C-2) and carried out finish the internal pressurization operation by section 172B-1 of portion and 172B-2 before.Shown in Figure 17 A and 17B, inner segments 172B-1 and 172B-2 are configured with outward extending gap regions 174 and 175, and this zone design becomes and outer segments 172A-1,172A-2,172C-1 and 172C-2) on corresponding gap regions match.Therefore, externally pressurize by intermediate section 172B-1,172B-2 before the pressurized operation if attempt, gap regions 174 and one of 175 or both will engage with the regional corresponding outer segments of not pressurization right, cause " the two pressurization " attempted operate and pressurize invalid.For example, if section 172A-1 of use portion and 172A-2 carry out external pressurized and pressurize by intermediate section 172B-1 and 172B-2 subsequently, breach 175 (and shown in the ring the bottom on counterpart) will engage pressurization part section 172C-1 and 172C-2, cause " the two pressurization " attempted operate and pressurize invalid.In this way, pressure rings assembly 170 is tending towards guaranteeing that external pressurized operates in central pressurized operation and carries out before.
Because the size of carrying out the required power/merit of seal bead pressurization is usually less than keeping cooperating required situation, can regulate the breach of the embodiment shown in Figure 17 A and the 17B, make the initial driving of external pressurized ring portion section 172A-1,172A-2 and 172C-1,172C-2 can not finish two pressurizations that keep fully, but the driving of central portion section 172B-1,172B-2 not only causes the seal bead pressurization to finish, and causes to keep pressurizeing and finish.In this way, can utilize the whole merit output of the instrument that uses ring assemblies 170.In this structure, the operation of pressurization assembly parts but is divided into the first local pressurized operation, the second local pressurized operation and the 3rd operation without separating into three same steps as, not only causes the 3rd pressurized operation completely, and finishes first and second pressurized operations.
Figure 18 A and 18B general description can be used for engaging pressurization and make another devices 180 of pressurizing tool pressurization assembly parts when the merit that the required merit of pressurization assembly parts produces greater than the instrument single actuations.Usually, Figure 18 A and 18B explanation comprises the hydraulic coupling multiplier 180 of first end 181 and the second end 182.First end 181 is applicable on the end that is attached to the standard pressurizing tool, and comprises the first piston 183 of first hydraulic cylinder that is positioned at the piston motion by the pressurizing tool (not shown).The driving of pressurizing tool will cause first piston 183 motion and the corresponding distances of tool stroke, and will force hydraulic fluid to flow through check-valves 184 to enter second hydraulic cylinder.Fluid is introduced second hydraulic cylinder will cause second piston 185 along second stroke motion.By repeating to drive pressurizing tool, the equipment of Figure 18 A and 18B will cause second piston 185 to travel greater than the stroke of the stroke of compression tool, cause the merit output of combine component of the equipment of compression tool and Figure 18 A and 18B to surpass the maximum work output of the single actuations gained of pressurizing tool.In addition, because in case the initial driving of user by pressurizing tool begins pressurized operation, pressurizing tool will be locked on the pressurization assembly parts easily, and till the pressure manual release in second cylinder or till pressurization is finished, the equipment of Figure 18 A and 18B uses easily.Equally, in case the user begins pressurization, the user can remain on its hand on the position; The required motion of user is the driving again (for example by pulls trigger and " rifle formula " instrument) of pressurizing tool.
In the embodiment of Figure 18 A and 18B, first and second pistons 183 and 185 are subjected to the spring bias voltage, so that the pressure after cylinder when discharging, turns back to fixed starting-point.In the embodiment shown, down curved (kick down) relief valve 186 is arranged so that the pressure of second cylinder in second cylinder and the merit that is enough to realize required extruding result are exported and withdraws automatically when corresponding.Similarly curved valve can be provided for first cylinder down.Replace curved relief valve down, the standard relief valve also can be used for manual release.
In the embodiment of Figure 18 A and 18B, second cylinder is illustrated as having greater than the diameter of the diameter of first cylinder and the stroke of being longer than the first cylinder stroke.Therefore owing to the effective increase of the power that comes from instrument and because the stroke of instrument increases, after the repeatedly driving of instrument, come from effective merit increase of compression tool.In the selected embodiment that it is contemplated that, an increase power or only increase stroke.
Have the pressurizing tool pressurization assembly parts that the merit greater than the maximum one stroke merit output of instrument needs except making, the equipment of Figure 18 A and 18B has potential advantage and is by using feedback sensors and analog to strengthen the valid function of instrument.For example, pressure and/or other sensor can be added on the equipment of Figure 18 A and 18B, so that measure the pressure in first and/or second cylinder, and/or the stroke of first and/or second piston.This information can offer for confirmation and/or judgement extrusion process of equipment in the outside.In this way, the element of " instrumentation " can convert non-instrumented instrument to the instrumentation instrument.
Another advantage of Figure 18 A and 18B is to use the main actuator outside the standard pressurizing tool to obtain required pressurization.For example, the actuation element outside the pressurizing tool can be used to realize the required motion of first piston.In the embodiment that it is contemplated that, the supply spiral is used for the motion first piston.This embodiment of selection can be under the irrational situation of the cost of whole compression tool and/or can not obtain electric power and/or can not use under the situation of electrification.
Though the equipment of Figure 18 A and 18B is illustrated as having first and second hydraulic cylinders of end-to-end location, should be understood that to have and to select structure.For example, can be by side by side or stacked up and down so that with the more close end user's of center of gravity of entire tool/apparatus assembly hand with two hydraulic cylinders, thus make this structure complicated more.In addition, the size that can use small-sized, high-pressure and hydraulic device and/or valve less than exemplary down curved valve to reduce the unit.
Though described the present invention with reference to preferred embodiment, those of ordinary skills can carry out tangible modification and remodeling.Therefore, planning the present invention farthest comprises all these modification and remodeling in the scope that falls into claim subsequently or its equivalents.
