Description

1288059 . IX. DESCRIPTION OF THE INVENTION: - TECHNICAL FIELD OF THE INVENTION The present invention relates generally to a device for crimping a joint to join individual pipe segments, and more particularly to a device for crimping such joints . [Prior Art] A deflated joint is typically a tubular sleeve containing a seal. In order to knit the end of the tube, the joint is compressed in the radial direction. The compression joint forms a leak proof joint between the ends of the tubes. This type of joint has a large > (four) mechanical strength and is self-supporting. For this type of joint, use the - buckle tool. The dust button tool generally includes a relocation tool including a piston cylinder and a force for converting the motion of the piston to a force applied to a press fitting to press the joint to the pipe segment to be joined. Pack of 4. For some pipe diameters, press the crimping clamp to the crimping tool and place the (4) buckle sweet around the joint to be crimped. For such solutions, the hydraulic pistons in the crimping tool will typically include rollers that will roll along a linear path to contact the wall of the crimping jaws when the piston is actuated. When the tool is actuated, the piston will move along a linear path - a fixed distance so that its rollers abut the piston against the arms. The rollers are in a linearly snapped manner to splice the ends of the sweets and rotate them and press the compression joints between the clamps. An example of a crimping tool including a press-clamp is provided in Figures 1 and 2. For certain pipe sizes (usually larger), the use of press-clamps is limited due to the construction - the tongs that can be easily moved and large enough to be mounted around the shackle are often difficult and difficult to handle. . In such applications 106527.doc 1288059 ', ' it is often used to press the buckle or the buckle to facilitate the crimping operation. In this case, etc., a press ring is placed around the joint to be crimped and a press and loop actuator is coupled to the press tool. The snap ring actuator is similar to a press-flange clamp because it includes a swivel arm, but the snap ring actuator interfaces with the snap ring to actuate the tool (and thereby cause the snap ring to actuate) The rotation of the clamp of the device will apply a force to the compression ring to press the joint. In general, the crimping tool is designed to cause the hydraulic piston to move along a fixed distance path each time the tool is actuated. For a given tool, the linear distance that the piston calls to move is often referred to as the tool"stroke". The force output of the piston as it moves along the stroke will depend on the specifications, geometry and other characteristics of the cylinder and piston. In general, the maximum value of the "work" output that the crimping tool can provide during a single stroke of the piston will correspond to the force output of the tool multiplied by the distance traveled by the piston when the tool is actuated. For example, a typical maximum power output of a tool capable of providing a force of 32 kN and a piston stroke of 40 mm would be 1.280 kN-m. In reality, it is impossible to utilize 1% of the maximum theoretical work output due to, for example, the inherent limitations of the system: the gap between the multiple components and the combined tolerance and the sweetness of the roll when the roller is retracted Open the required operating conditions - it can waste a stroke of about 15 mm. If the same tool is intended to be used for both small crimping tubes (where crimping clamps or small crimping rings will be used) and for larger tube sizes (large dust rings may be used), then The limit of the maximum work output of an established press tool will be a challenge. For some applications, the tool's maximum output is insufficient = the value of the work required to fully buckle all the dust-and-buckle joints that might be expected to use the tool. Correspondingly, J06527.doc 1288059 for large and small magic buckle joints may be forced to carry and maintain small crimping tools (for small joints) and large one-button tools - for their needs The output of the large press-fit joint is larger than the output of the small jade. This type of situation where multiple tools are required can result in cost, maintenance, increased equipment requirements, and other adverse consequences. Although in some systems a single cable and multiple actuators (clamps) are used to achieve the two-step press-fitting operation, in the autumn, due to the need to use multiple actuators, it will involve a significant increase in use and transportation. The weight, and the need to remove the first actuator from the tool and replace it with a second actuator during the dusting process, can complicate, cumbersome, relatively slow and can be prone to errors. SUMMARY OF THE INVENTION The present invention is directed to a device for enabling a crimping tool to effectively and easily crimp a joint when the work required to press the joint is greater than the work produced when the crimping tool is subjected to a single actuation. SUMMARY OF THE INVENTION The present invention is directed to a work performed when a press-fit is applied to a joint is greater than when a press-fed tool is subjected to a single actuation or when a multi-step press is desired. The buckle tool assembly can easily and easily implement a crimping device for the joint. [Embodiment] Referring to the drawings, and more particularly to Fig. 1, an exemplary crimp tool assembly 10 is shown. Assembly 10 includes a crimping tool 12 and a lost jaw assembly 14. The crimping tool 12 includes a generally gun-shaped device that includes a means for use in a manner known to those skilled in the art. Actuate the clamp total 106527.doc 1288059 into a hydraulically actuated piston assembly (not shown in Figure 1 or 2). The crimping tool 12 can be powered by a battery or cable, and examples of conventional crimping tools that can be used to practice the subject matter of the present invention include CT-400 and 320-E crimping tools available from Ridge Tool Company. Figure 2 is a side elevational cross-sectional view generally showing the assembly 1 of Figure 1. As reflected in the figure, the clamp assembly 14 defines an opening 34 at its peripheral end that is sized and shaped to engage a crimp joint and is achieved when the clamp assembly 14 is actuated The crimp of the joint. As further reflected in this figure, the crimping tool 12 includes a hydraulically actuated piston assembly 30 including rollers 32A and 32B. When the crimping tool j 4 is actuated by, for example, pressing a trigger or switch, the hydraulically actuated piston assembly 30 will move along a path of travel toward the jaw assembly 14, thereby engaging the rollers 32A, 32B with the jaws The ends of 16A and 16B thereby cause the clamps 16A and 16B to close together, and if a press-fit joint is located within the opening 34, the joint is thereby crimped or partially crimped. Figure 3 generally shows that a crimping connection is not used to achieve a crimp connection. As illustrated in the figure, the crimping tool 12 is coupled to a snap ring actuator assembly 30. The snap ring actuator assembly is similar in construction to the crimp clamp 14 described above, the main difference being that the arm of the press ring actuator assembly is designed to interface with the snap ring assembly 32. In the illustrated embodiment, the compression ring assembly 32 is formed by two generally semi-circular portions that are coupled together at a pivot point. In use, the compression ring assembly 32 is placed around the crimp joint 35 to be crimped, and the tip end of the compression ring actuator assembly 30 is placed in a notch formed in the compression ring assembly 32, and Dynamic crimping tool 12. Actuation of the crimping tool causes the arm of the compression ring actuator assembly 30 to move and compress the compression ring assembly 32 and the connector 35 that surrounds the cloth 106527.doc 1288059. As noted above, for certain sizes of joints, the value of the work produced by the crimping tool upon one actuation (eg, for the piston-type tool 12 shown in Figure 3, which will actuate the actuator) Not enough to fully crimp the crimp joints in question. Thus, in order to complete the crimping operation, it may be necessary to actuate the crimping tool multiple times. Since the stroke and force are limited for a given crimping tool, the same crimping tool, the snap ring actuator assembly and the press ring assembly may not be able to complete the crimping operation without adjustment. The invention provides an adjustable engaging surface for the press-fit garment dynamic assembly, the press-fastening ring assembly, or a combination thereof, which can effectively adjust the spacing between the compression portions of the members, so that the monthly b is sufficient to use the pressure The same stroke of the buckle tool achieves further compression. These adjustments are used for U to exceed the increased work capacity of the normal capacity of the components without adjustment. - Figure 4 shows - an example of a wear-resistant buckle that can be achieved when the buckle tool needs to be actuated multiple times. Referring to the figure, a snap ring actuator assembly 40 is shown. The ring actuator assembly 4 is generally constructed in accordance with a conventional practice of the dust ring actuator: the main difference is that the snap ring actuator assembly includes a replaceable tip 42. The replaceable tips include a first set of tips having a shape and configuration, and a second pair of tips 43 including a second shape and configuration, the second geometry and configuration being at least one aspect In the case of private silver, the size of the replaceable tips is different, so the way of the (4) buckle assembly will be different, and the use of the buckle actuator assembly shown in Figure 4 can be effectively used. Buckle the work. For example: also... two J fines are implemented in a conventional manner using a pressure 106527.doc 1288059 buckle actuator assembly 4〇, a compression ring assembly and a crimping tool, using a first set of tips 42 to implement a Initial crimping operation. The crimp ring actuator assembly 4〇 can then be removed from the pressure retaining ring, the tip 42 replaced with the tip end 43, and the crimping tool coupled by the modified snap ring actuator assembly 40 Connected to the crimping % assembly. The crimping tool can then be actuated a second time to provide the required additional work to complete the crimping operation. Further, it may be desirable in some situations to use three or more steps to complete the crimping operation. By way of example and not limitation, the first step can be accomplished by two identical actuator tips 42 mounted. Next, an actuator tip having a different geometry can be used to replace an actuator tip and complete the second step. Then, a second step can be accomplished using two identical actuator tips 43. The remaining steps can be accomplished using more replaceable tips of different geometries similar to the tips 43. In the embodiment shown in FIG. 4, the tips 42 and 43 are coupled to the damper clamp by an interference fit assembly. The interference fit assembly includes an arm located in the actuator assembly 40 (not shown). In the recess opening, the recess opening receives a protrusion extending from the ends 42 and 43. An example of a method for coupling the interchangeable tips 42 and 43 to the clamp of the actuator assembly 40. Other methods and techniques can also be used, such as interlocking "smart toys" pieces, pins and receiving slots and the like. β Figure 5 shows an alternative method for achieving a quick and convenient, two-step "squeeze and, in general, a multi-step press. Specifically, t, a cross-sectional view of an exemplary embodiment of a ring assembly 50 and a crimp ring actuator assembly 52 constructed in accordance with certain disclosures of the present invention. In general, ° 106527.doc 1288059

The compression ring assembly 50 is constructed in accordance with conventional techniques for constructing a compression ring assembly. However, in the illustrated embodiment, the recess that normally receives the compression ring actuator assembly includes two pin-like members 54a and 54b. In the illustrated embodiment, the tips of the jaws of the actuator assembly 52 are configured to engage one of the members 54a or 54b. Thus, for a two-step operation, a first press-fitting operation can be performed by squeezing the snap ring actuator assembly 52 at the element 54a to the press-fit ring assembly 5' and then in the first pass After the actuator is coupled to the actuator assembly, the tip of the compression ring actuator assembly 52 can be repositioned to engage the component 54b, thereby achieving a second dusting operation. In this manner, There is almost no need for complicated operation (4), so that a multi-step press-fitting operation can be easily achieved. If additional steps are desired, additional pin-like members 54A and 54B can be added to the assembly to achieve a three-step process. Or more step-and-push process. Figure 6 shows an alternative press ring assembly 6 that can be used to achieve a multi-step press. In the illustrated embodiment, the snap ring assembly 6Q includes a conventional dust for receiving a groove 仏 and (4) of the tip end of the buckle actuator. The movable members 64a and 64b are positioned by the groove core and the heart, the movable member ... and (10) are rotatable to a fixed position to adjust the geometry of the groove and The way the crimping actuator rings the ring assembly 6〇 by this side The pressure can be constructed for the -first crimping operation by positioning the movable member 64a at the position of the & ,, and then the ring ′ is then moved or adjusted by the movable member “a and secret” for the post-operation To reconstruct the compression ring. It should be noted that the inner diameter profile 65 of the ring assembly 60 is added to be used with a "specific dust button joint." The inner diameter can be machined in a variety of shapes. 106527.doc • 12- 1288059, depending on the joint of the clamp. The formation may include an arrangement for simultaneously sealing the sealing bead of the joint with the retaining button region. The concept of shaped inner diameter can be applied to all of the crimp rings described herein. Figure 7 shows an alternative embodiment of the embodiment shown in Figure 6. In Fig. 7, a crimp ring assembly 70 including grooves 72a and 72b and movable members 74a and 74b is shown. Like the movable member of Fig. 6, the movable members 74a and 74b can be adjusted to change the geometry of the grooves 72a and 72b to achieve a multi-step crimping operation. In the example shown in Fig. 7, the movable members 74a and 74b are adjusted by linear motion (e.g., sliding). Figures 8A and 8B show still further embodiments in which the geometry of the recess of a clamp that receives a crimp ring actuator assembly therein is advantageous for multi-step crimping operations. In both embodiments, the movable member defining the surface for receiving the crimp actuator actuator tip is rotatable and rotatable out of a fixed position such that the tip of the actuator assembly can be The crimp ring assembly receives a configuration that is not received by the movable member, and a second configuration in which portions of the movable member receive the crimp ring actuator assembly jaws to operate the buckle ring Assembly. In the embodiment shown in Figure 8a, the rotatable elements 82a and 82b are attached to the main wear ring assembly at a location outside the recess of the receiving actuator assembly jaw, as shown In the embodiment, the rotatable elements 8 4 a and 8 4 b are coupled to the press ring at a point located in the recess. Figure 9 shows yet another embodiment of a movable member in which a snap ring assembly 90 is provided with slidable members 94a and 94b in recesses 92a and 92b, and slidable members 94a and 94b are moved to certain positions to change Dust clasp assembly 9〇106527.doc 13 1288059 Interconnecting an application to the ring assembly 90^ buckle (4) (4) (4) Figure H) shows an example dust clasp with a movable component alternative design (4). The non-% assembly includes the movable component chest and secret, a movable component 1.02 & and l02h than ^ij 八r mother. , r ?_ white includes a groove ^ 钧 and (7) servant for receiving - the buckle The tip of the actuator assembly. In the figures 102a and 102b, the main part is connected to the ratchet wheel _106a and the secret light by a dedicated address. In use, π - 々 pi can adjust the position of the actuator jaw adapter ring assembly 100 by adjusting the position of the component 1 〇 2a and the position between the various crimping steps. In this way, it is easy to achieve a multi-step press. A release mechanism constructed in accordance with conventional techniques can be provided to permit re-adjustment of the movable members 102a and 102b. Figure 11 shows a compression ring, a heart, 110, which includes a recess 112aA 112b for receiving the tip end of a compression ring actuator. The two main portions of the compression ring assembly 110 are surface-contacted by an adjustable hinge member m that includes - a pin having a different core section (1) adjustable - thereby viewing the pin 116 The position is placed to change the point at which the two main elements of the compression ring assembly 1 are rotated relative to each other with respect to each other. In this manner, the compression ring assembly can be configured to operate in a first configuration for a first crimping operation, and then the pin 116 can be repositioned to change the ring assembly 1 for a subsequent repeating operation. 1 〇 structure. Figure 12 shows a compression ring actuator assembly 120 that uses a pin having a different core portion to achieve a multi-step crimping operation like the compression ring assembly u' in the Bebega example. The arms of the arms are coupled together at two hinge points 122A and 122B. Each hinge point includes a pin having a different core portion 106527.doc 1288059 points 1 24, wherein the pin can be adjusted to change the configuration of the compression ring actuator assembly. In the embodiment of Figure 12, a coupling element 126 is used to ensure that the pins associated with the drum joints 12 2 A and 12 2 B rotate in tandem. Figure 13 shows a set of actuator clamps 130 that are quite plentiful using the set of actuator clamps 130 for the compression ring assemblies and other compression ring assemblies illustrated in Figures 6-11 above. As noted above, each of the compression rings reflected in Figures 6-11 can be adjusted to provide a variety of configurations to allow the actuator arms to engage the compression ring in a manner that is adjustable. In many cases, the same set of snap ring actuator assemblies can be beneficially used to perform crimping operations in a variety of configurations. In some cases, however, it may be desirable to adjust the distribution of forces applied to the compression ring to suit a particular ring configuration. The actuator assembly 13 shown in Figure 13 achieves this result by providing a plurality of cam members 131 and 132 that serve as locations in which the hydraulic piston will interact with the actuator assembly 130. . In a first crimping operation in which the jaws can be in their widest positions, the rollers will tend to interface with the actuator assembly 13〇 at the cam member 131, thereby The movement provides a specific force distribution as it moves through its stroke. Due to the expected compression of the joint, or due to the crimping (four)

Crimping Assembly, (as w〇 (as disclosed in W〇 03/022480)

Break into this article. The application of the force in various multi-step press-fit ring assemblies can be optimized by using the application of the actuator, which has a special bevel of 106,527.doc 1288059. Figure 14 shows a press-and-loop interlocking concept that can be used with any multi-step buckle ring assembly 'including but not limited to the multi-step clasp assembly described above in connection with Figure 6-u. Referring to Figure 14, the interlocking feature includes a plunging-patch mechanism 140 into the shackle assembly. In the illustrated embodiment, the ratchet assembly includes a toothed surface 142 formed on one of the main members of the press ring and a rotatable cog coupled to the other of the presser rings 144. The cogs are spring biased to engage the toothed surface 142. When the compression ring assembly is compressed about a press-fit joint, one of the engagement elements of the cog 144 will move within the toothed surface 142 and tend to prevent the buckle I assembly from re-establishing the initial crimping operation. (4). After the initial crimping process, the crimping ring assembly will be "locked" to the crimping joint and cannot be removed (there is no manual release of the cogs). This locking prevents the user of any multi-step ring assembly (including the multi-step press assembly) from completing the press-fitting operation. In the illustrated embodiment, the configuration and biasing of the cogs 144 and the size of the toothed surface 142 are such that upon completion of the crimping process, the cogs are automatically disengaged and allowed to open and remove the compression ring. to make. In the embodiment shown in Fig. 14, the ratchet mechanism 14 is repeatedly present on both sides of the illustrated % fastener assembly. Alternative embodiments are contemplated in which the ratchet is located on only one side of the compression ring assembly. According to still another teaching of the present invention, a crimping operation is performed in which the crimping process is broken down into two or more discrete steps, including at least one of the following steps: wherein a crimp is implemented to provide a retaining crimp to join the joint Retained in

1 _7.dOC -16· 1288059 The pipe is crimped with the joint and at least one press is applied to provide a snug seal. Figures 15A and 15B show a compression ring assembly 150 that is particularly suitable for use in this form of multi-step crimping. Referring to Figures 15A and 15B', a compression ring assembly including six generally semi-circular segments 152A-1, 152A-2, 152B-1, 152B-2, 152C-1, and 152C-2 is shown. The generally semi-circular segments 152A-1, 152A-2, 152B-1, 152B-2, 152C-1, and 152C-2 form a plurality of snap ring segments that are spliced together for rotation about a common point 154. Each of the circular segments defines a cavity sized to receive the tip end of a pair of actuator arms. The size and design of the ring assembly is such that, in use, the ring assembly will be placed over a joint to be crimped. When so positioned, segments 152A-1 and 152A-2 will be positioned over a portion of the joint to initially hold the buckle to one of the tube members to which the joint will be coupled, and segments 152B-1 and 152B-2 will be positioned to compress. One of the joints is buckled to achieve a seal against the sealing bead, and the segments 152C-1 and 152C-2 are positioned to provide a retaining buckle for the other tubular component to which the joint will engage. After the 5H assembly is positioned around the 接头海接头, the pair of actuator sweet tips will be positioned within the cavity defined by segments 152Α-1 and 152Α-2, and the tools to which the clamps are coupled will Actuated, thereby forming a retaining buckle to secure the joint in question to one of the tube elements to be coupled. The tool will then move so that the tips of the actuator arms are positioned within the cavity defined by segments 152Β-1 and 152Β-2 and the tool will be actuated to achieve a sealed bead buckle. Finally, the tips of the actuator jaws will move into the cavity defined by segments 152C-1 and 152C-2 and be actuated a third time to achieve a second holding buckle. 106527.doc 1288059 It should be noted that the compression ring assembly 15〇 shown in Figures 15A and 15B is intended to be used to position a retaining buckle region on both sides of the joint and to have a space between the two holding C-lock regions. Press-fit joint in the sealing bead area. It should also be understood that additional semi-circular ring segments can be added along the axis to accommodate other joint designs that require multiple retaining or sealing bead positions to achieve multi-step clamping. In addition, some connectors may need to rearrange the semi-circular pairs. For example, the mouthpiece may require side-by-side retention of the crimp and a bead seal located at the axial end of the joint, such as the joint currently available from Mapress or Y〇rkshire. In the above example, the crimping of the sealing bead is performed after the completion of the first holding crimp. It should be understood that the process is merely exemplary and may follow other processes. For example, a process in which the sealing bead buckle is first implemented and finally the holding of the clasp is performed or the two holding clasps are completed first and the sealing bead buckle is implemented as the final crimping operation. Figure 16 shows a compression ring assembly 16" similar to the compression ring assembly described above in connection with Figures i5A and 15B. However, in this design, the outer side sections 162A-1, 162A-2, 162C-1, and 162C-2 of each ring segment are designed with notched sections 164, 165 and located on sections 162A-2 and 162C-2 ( Corresponding notched sections, not shown in Figure 16, which intersect the intermediate sections 16^_丨 and 162B-2 to ensure that the central crimping operation must be performed first (i.e., in sequence) (sealing bead crimping) ). The notches 164 and 165 are arranged such that each of the outer pair is attempted (162A-1 and 162A-2 or 162C-1 and 162C-2) before completing the crimping of the intermediate pair 162B-1 and 162B-2. When a press is reached, it will cause the press to fail. This responder to the ring assembly user or the 106527.doc -18- 1288059 will provide the user with a button failure indication. . The crimping failure is ensured by the fact that the notches 164 and 165 (and the notches on the underside of the ring) are designed such that when the outer segment is actuated prior to actuating the intermediate segment, the outer segments will be caused to engage the intermediate segment, And thereby causing the actuator tool to attempt to perform both crimping operations when the outer segment is crimped prior to the end of the crimping of the intermediate section. Since the tool output is not sufficient to perform both crimping operations in the application in which the ring assembly 160 will be used, the attempted crimping operation will fail. If the intermediate press is first implemented, the intermediate sections 162B-1 and 162B-2 will tend to close or partially close due to deformation of the crimp joint in the crotch region. Therefore, thereafter actuating the outer section will not cause the inner section to engage or the "double press" operation attempted. Accordingly, the ring assembly 16A provides a structure that tends to ensure that the intermediate crimping is performed in sequence prior to the end of the external crimping. Similar to Figures 1 5A and 15B, additional ring segments can be incorporated in the axial direction. In addition, the arrangement of the sealing beads on the inner diameter of the ring and the shape of the holding buckle can be rearranged according to the joint design of the ring to be pressed. Circles 17A and 17B show a crimp ring assembly similar to that described above in connection with Figures 15A, 15B and 16. However, the structure shown in Figures 17A and 17B is designed to ensure that the outer crimping operation is performed prior to completion of the inner crimping operation by sections 172B-1 and 172B-2 (using segments 172A-1, 172A-2, and 172C-1 and 172C-2). As shown in Figures 17A and 17B, the inner segments 172B-1 and 172B-2 are configured with outwardly extending notched regions 174 and 175 that are designed to be aligned with the outer segments 、2Α, 172A- 2. The corresponding corresponding notched areas of 172C-1 and 172C-2 are matched. Accordingly, if an attempt is made to perform the crimping by the intermediate sections 172B-1 and 172B_2 before the completion of the external crimping operation, the one or both of the notched regions 174 or 175 will be engaged to correspond to one. The outer segment of the area that has not been buckled, causing an attempt to perform, double press, and work and the buckle is failed. For example, if segment 172 VIII and i72A-2 are used to implement an outer crimp and then attempt to implement a crimp by the intermediate segment 172B] & 172b_2, the notch 175 (and its bottom on the bottom of the ring shown) The counterpart) will engage 172C-1 and 172C-2, causing an attempt to perform a "double press, work and crimp failure. In this manner, the snap ring assembly 17 tends to ensure that the outer crimping operation is performed prior to the crimping operation of the central crimp. Since the force/work value required to implement the sealing bead buckle is often less than the force/work required for the holding fit, the design of the embodiment shown in Figures 17A and 17B can be adjusted to the outer crimp ring segment 172A- 1. The initial actuation of 172A-2 and 172C-1, 1 72C-2 will not completely complete the two holding buckles, but the result of actuation of the intermediate sections 172B-1 and 172B-2 will not only complete the sealing bead pressure. The buckle will also complete the holding of the buckle. In this way, the full work output of the tool used with the ring assembly 170 can be utilized. In this design, the work for performing the crimping on the joint is not divided into three equal parts, but is divided into a first partial crimping operation, a second partial crimping operation, and a third operation. Not only will a complete third crimping operation be achieved, but also the first and second crimping operations will be completed. 18A and 18B generally illustrate another device 180 that can be used to perform a press when the work required to press a joint is greater than the work produced when a single press of the press tool is actuated, thereby enabling the press tool The joint can be crimped. In general, Figures 18A and 18B show a liquid pressure multiplier i8, which includes a first 106527.doc -20- 1288059 food and 1 8 1 and a second end 1 82. The first end 181 is adapted to be attached to the end of a standard crimping tool and includes a first piston 183 ′ in a first hydraulic cylinder. The first piston 183 can be attached by a crimping tool (not shown). The piston moves. Actuating the crimping tool will move the first piston 183 a distance corresponding to the stroke of the tool and will force hydraulic fluid through a first check valve 184 into a second hydraulic cylinder. The introduction of fluid into the second hydraulic cylinder will cause a second piston 1 85 to move along a second stroke. By actuating the crimping tool in reverse, the apparatus of Figures 18A and 18B will cause the second piston 185 to travel a stroke greater than the stroke of the crimping tool, thereby combining the crimping tool with the device of Figure i8A and the device. The output of the assembly exceeds the maximum work output that can be obtained from the press tool by the single: In addition, the device shown in FIG. 18A and the device are easy to use, because once the user starts the pressing operation by initially actuating the pressing tool, the pressing tool is likely to be locked on the pressing joint until the second cylinder is manually released. The pressure in the middle or until the completion of the press. In addition, after the user starts to buckle, the user can place his or her hand at a certain position. 'The only action the user needs to perform is to re-actuate the button tool (for example, by pulling a " grab type, , the trigger on the tool). In the example of the sinus yoke shown in Figs. 18A and 18B, both the first piston 183 and the second piston 185 are biased by the spring to return to the fixed state when the pressure on the rear of the cylinder is released. Start point. In the illustrated embodiment, an automatic snap-off bleed valve 186 is provided to provide a first-cylinder pressure in the second cylinder corresponding to a work output sufficient to achieve the desired press-down result. This is enough to automatically retract. A similar automatic jumper valve can be provided for the first cylinder. Standard bleed valves can also be used with manual bleed to replace the automatic hopping valve. 106527.doc - 21 - 1288059 In the embodiment shown in Figures 18A and 18B, the second cylinder is shown to have a diameter greater than the first cylinder and a stroke greater than the first cylinder. Therefore, after a plurality of actuation of the crimping tool, the effective work output from the crimping tool is increased, both because the force from the tool is effectively increased, and because the stroke of the tool is increased. Alternative embodiments in which only force increases or only strokes are large are contemplated. The apparatus shown in Figures 18A and 18B also has the function of enhancing the effective operation of the tool by means of feedback sensors and the like, in addition to enabling a crimping tool to press a joint having a required work greater than the maximum single-stroke work output of the tool. Potential advantages. For example, a pressure sensor and/or other sensor may be added to the apparatus shown in FIGS. 18A and 18B to measure the pressure in the first cylinder and/or the second cylinder and/or the first piston and/or The actual stroke of the second piston. This information can be provided external to the unit for confirmation and/or diagnostics of the crimping process. In this way, an "instrument" component can transform a non-instrumental tool into a tool. A further advantage of the apparatus shown in Figures 18A and 18B is that it allows for the use of a different primary crimping tool, the primary actuator, to achieve a desired pressure. For example, an actuation element that is identical to a crimping tool can be used to achieve the desired motion of the first piston. Embodiments in which a feed screw is used to move the first piston are contemplated. Such alternative embodiments may permit the use of a crimp joint in situations where the cost of one of the complete crimping tools is not cost effective and/or where there is no force and/or undesired use of electrical power. Although the apparatus shown in Figures 18A and 18B is shown with first and second hydraulic cylinders positioned end to end, it will be appreciated that alternative configurations are also possible. Example 106527.doc -22- 1288059 In other words, the design can be made more compact by stacking the two liquids (four) side by side or by stacking the two hydraulic cylinders with each other to make the entire tool/device assembly Focus on, closer to the hands of the end user.
