Definitions
- the present invention relates to a crimping head and an installation for crimping comprising at least one such crimping head.
- crimping head for the automated assembly of profiles connecting to form a dihedral, said crimping head comprising two jaws with at least one tool-holder part and a moving drive device by pivoting said jaws between a separated position and a close position of said tool holder parts to cut a crimping tab in the wall of the profiles to be connected.
- Patent FR 2 887 792 describes a crimping head which uses two tool holder jaws to produce the crimping tongues.
- the tools have teeth capable, during the approximation of the jaws, of cutting and deforming the constituent material of the profile so as to form a tongue which cooperates with a square placed in the connection angle of the profiles so as to secure said profiles.
- Such an operation requires for its success a perfect synchronism of the jaws.
- a movement drive mechanism for the jaws, as described in patent FR 2 887 792, is satisfactory, but this mechanism is complex and therefore expensive.
- Document DE 19532564 also describes a crimping head which uses two pressing members to perform a crimping operation.
- An object of the invention is to provide a crimping head of the aforementioned type, the design of which is simplified while limiting the breakage of the tools of said crimping head.
- the subject of the invention is a crimping head, in particular for the automated assembly of sections connecting to form a dihedral, said crimping head comprising two jaws with at least one tool-holder part and a device for driving said jaws in pivoting movement between a separated position and a close position of said parts tool holder, each jaw having the shape of an arm, the arm of each jaw being an arm pivoting about a pivot axis, the pivot axes of the arms being parallel, each arm having a first arm section and a second section of arms, the first arm section and the second arm section of each arm being arranged one, on one side, the other, on the other side of a plane passing through the pivot axes of the said arms, the first section of each arm being equipped with the tool holder part of the jaw, characterized in that the device for driving the jaws in pivoting movement comprises, disposed at least partially between the said second arm sections, a cam in contact with sliding or rolling support with the second section of each of the arms and
- the second section of each arm cleans, at the level of its part capable of coming into bearing contact with the cam, a so-called cam surface and the cam surfaces of the arms. form between they of the surfaces converging in the direction of the pivot axes of the arms.
- This geometric arrangement allows a simple course of the cam.
- the cam surfaces form between them the branches of a V pointing towards the pivot axes of the arms.
- the cam in rolling bearing contact with the second section of each of the arms is equipped, at the level of each bearing contact zone, with at least one roller mounted free to rotate.
- the jaws in bearing contact of the cam with said second sections of the arms, are, in the state driven in movement of the cam by said actuator in a second direction. opposite the first direction, mounted so as to pivot in the direction of separation of the tool-holder parts, and the crimping head comprises a member for restoring the jaws to the position apart from said tool-holder parts.
- the member for restoring the jaws to the spaced position of said tool-holder parts is a spring arranged between the second sections of the arms.
- the crimping head is equipped with a centering V projecting between the first sections of the arms.
- This centering V is configured to match the apex of the dihedral angle formed by the profiles to be assembled. This centering V thus prevents, during the crimping operation, an offset of the sections at the top of the dihedral formed in the support position of an angle of the frame formed by the sections on said centering V.
- said crimping head comprises, for the tool holder part of each jaw, a cutting tool that can be removably coupled to said tool holder part.
- This cutting tool can be formed by one or more crimping teeth.
- the centering V is arranged between the cutting tools in the position close to the tool holder parts of the jaws.
- the jaws and the device for driving the jaws in pivoting movement are mounted on a common support.
- This common support can thus be easily installed on a mobile frame.
- the crimping head comprises at least one clamping device, said clamping device comprising at least one articulated arm carried by said support and a pressing member arranged at the end of the arm articulated, this pressing member being associated with an actuating member, such as a cylinder, for movement of said pressing member between a separated position and a position close to the support.
- a clamping device allows the profiles to be assembled to be held in position.
- the presser member can be positioned at least partially above and plumb with the centering V. This pressing device makes it possible to avoid an offset of the sections in a direction parallel to the edge of the dihedral formed by the sections.
- Another subject of the invention is an installation for crimping, in particular frames formed of four sections, characterized in that said installation comprises four crimping heads in accordance with that described above and a control unit configured to control synchronous operation of the four crimping heads.
- the four crimping heads are mounted on a frame of the installation.
- Figure 1 shows a perspective view of a crimping head according to the invention
- Figure 2 shows a partial perspective view of a crimping head according to the invention in the spaced position of the tool holder parts of the jaws;
- Figure 3 shows a partial perspective view of a crimping head according to the invention in the close position of the tool holder parts of the jaws;
- FIG. 4 represents a partial perspective view taken from below of a crimping head according to the invention in the spaced position of the tool holder parts of the jaws;
- Figure 5 shows a perspective view of an installation for crimping according to the invention.
- the crimping head 1, object of the invention, is used in the example shown to connect two sections (not shown) together.
- This crimping head 1 is generally integrated into an installation 20 for crimping which comprises four crimping heads 1 as illustrated in FIG. 5.
- This installation 20 allows the crimping of a frame formed of four sections.
- the crimping heads 1 are mounted on a frame which can have a large number of shapes.
- the frame comprises two parallel beams mounted movable in the direction of a ratment and a spacing from each other.
- Each beam carries two crimping heads 1 mounted on a movable beam in the direction of bringing them closer together and moving them apart from each other.
- This arrangement makes it possible to manage the crimping of frames of different dimensions.
- These frames are generally metal carpentry frames, such as door, window or other frames.
- Each frame profile is in the form of a tubular element.
- Each profile of the frame is assembled at right angles to another profile of the frame by a bracket inserted into the cavities of the profiles to form a dihedral.
- the installation 20 further comprises a control unit 21 configured to control the movements of the moving parts, such as the parts of the frame and the operation in synchronism of the crimping heads 1 which will be described in more detail below.
- This control unit 21 is in the form of an electronic and computer system which includes, for example, a microprocessor and a working memory. According to a particular aspect, the control unit can take the form of a programmable automaton.
- the functions and steps described can be implemented in the form of a computer program or via hardware components (eg programmable gate arrays).
- the functions and steps performed by the control unit or its modules can be performed by instruction sets or computer modules implemented in a processor or controller or be performed by dedicated electronic components or components of the FPGA type or ASIC. It is also possible to combine computer parts and electronic parts.
- the unit or means or modules of said unit are configured to carry out a given operation
- the crimping head 1 allowing the automated assembly of sections connecting by forming a dihedral comprises two jaws 2 each having a tool-holder part 3.
- This crimping head 1 further comprises a device 4 for driving in movement at pivoting of the jaws 2.
- These jaws 2 are each capable of cutting out a tab in the wall of one of the profiles to be connected.
- These jaws 2 are actuated simultaneously by the device 4 for driving the jaws in pivoting movement between a separated position and a close position of the tool holder parts 3 of the jaws 2 to guarantee the movement symmetry of the jaws 2.
- the jaws 2 and the drive device 4 in pivoting movement of the jaws 2 are mounted on a common support 15.
- This common support 15 has, in the examples shown, the shape of a plate mounted on part of the frame of the installation 20.
- Each jaw 2 has the shape of an arm 5.
- This arm 5 is an arm pivoting around 'an axis XX' pivot.
- the pivot axes XX' of the arms 5 are parallel.
- the axis XX' of each arm 5 is a so-called vertical axis which extends perpendicularly to the support 15 formed here by a plate.
- the axes XX' of the arms 5 extend perpendicularly to said surface.
- Each arm 5 has a first arm section 6 and a second arm section 7.
- the first arm section 6 and the second arm section 7 are arranged one, on one side, the other, on the other side of a plane P passing through the pivot axes XX' of said arms 5.
- the first section 6 of each arm 5 is equipped with the tool holder part 3 of the jaw 2.
- This tool holder part 3 is arranged at the level of the end of the arm 5 arranged on the first section 6 side of the arm 5 It follows that in the state driven in pivoting movement of the jaws 2, when the first sections 6 of said jaws 2 and therefore the tool holder parts 3 tend to move away from each other, the second sections 7 of said jaws 2 tend to approach each other and vice versa.
- the crimping head 1 comprises, for the tool holder part 3 of each jaw 2, a cutting tool 14 which can be removably coupled to said tool holder part 3.
- This cutting tool 14 has here the form of a crimping tooth.
- This tooth mounted on the tool holder part 3 of the jaw 2, is intended to penetrate into the constituent material of the profile and to cut a tab in the wall of the profile to be connected.
- This tongue is intended to cooperate with the bracket placed beforehand inside the angle formed by the two sections. The cooperation of the bracket with at least two crimping tabs formed in the wall of each profile makes it possible to secure the profiles and to maintain them in the crimping position.
- a crimping head operating in a horizontal plane, that is to say with the axis XX 'pivot of each arm 5 vertical, it can be provided to equip a jaw 2 of a series of teeth superimposed, that is to say arranged one above the other. Thus, several tongues can be cut simultaneously with the same movement of the jaw 2.
- the crimping head 1 is equipped with a centering V 13 projecting between the first sections 6 of the arms 5.
- This centering V 13 is arranged between the cutting tools 14 in the close position of the tool-carrying parts 3 of the jaws 2.
- This centering V 13 is able to match the vertex of the angle formed by the profiles and corresponding to the edge of the dihedral.
- This centering V 13 is mounted in a stationary manner on the support 15 and is therefore independent in movement of the jaws 2.
- the frame or the sections to be crimped are therefore prepositioned at this centering V before crimping, that is to say say before driving in pivoting movement of the jaws 2 in the direction of bringing together the tool holder parts 3.
- the device 4 for driving in pivoting movement of the jaws 2 comprises, arranged at least partially between said sections 7 of arms 5, a cam 8 in contact with sliding or rolling support with the second section 7 of each of the arms 5 and an actuator 9 for driving the cam 8 in displacement between two extreme positions, one corresponding to the spaced position of the tool holder parts 3 and therefore of the first arm sections 6, the other, in the close position of the tool holder parts 3 and therefore of the first arm sections 6.
- This actuator 9 for driving the cam 8 in displacement between two extreme positions corresponding, one, to the separated position of the tool holder parts 3, the other, to the close position of the tool holder parts 3, allows a movement of the cam 8 along at least a first direction D1 for the passage of the cam 8 from the extreme position of the cam 8 corresponding to the separated position of the tool holder parts to the extreme position of the cam 8 corresponding to the close position of the tool holder parts.
- This actuator 9 also allows, by driving the cam 8 in displacement in a second direction D2 opposite to the first direction, the passage of the cam 8 from the extreme position corresponding to the close position of the tool holder parts 3 to the extreme position. corresponding to the separated position of the tool holder parts 3.
- This actuator 9 is therefore a drive actuator in displacement and back and forth of the cam 8. Indeed, this actuator 9 is a drive actuator in displacement of the cam 8 in a first direction D1 and in a second opposite direction D2.
- the actuator 9 is here a cylinder whose body is fixed to the support 15 and whose rod is coupled to the cam 8.
- This actuator 9 is here a double-acting cylinder. This cylinder is therefore configured to drive the cam 8 in displacement in a first direction D1 for the passage of the cam 8 from an extreme position corresponding to the separated position of the tool holder parts 3 to another extreme position corresponding to the close position.
- this actuator 9 could have been produced in the form of two single-acting cylinders, one ensuring the movement of the cam in the first direction D1, the other, the movement of the cam in the second direction D2 opposite to D1.
- the actuator 9 could have been formed by a single single-acting cylinder in cooperation with an elastic return member. This or these jacks can be hydraulic or pneumatic or electric jacks. Generally, the working pressure of these cylinders is between 5 and 6 1O 5 .Pa. As a further variant, the actuator could have been a motor.
- the cam 8 is in sliding or rolling bearing contact with the second section 7 of one of the arms 5 and with the second section 7 of the other of the arms 5 to allow, in the driven state in displacement of the cam 8 in said first direction D1, by bearing contact with said second sections 7 of the arms, a pivoting movement of the jaws 2 in the direction of bringing together the tool holder parts 3.
- the jaws 2 are, by bearing contact of the cam 8 with the second sections 7 of the arms, in the state driven in displacement of the cam 8 by the said actuator 9 in a first direction D1, for the passage of the cam 8 from one of the extreme positions corresponding to the spaced position of the tool holder parts 3 to the other extreme position corresponding to the close position of the tool holder parts 3, mounted so as to pivot in the direction of bringing the holder parts closer together -tool 3.
- the contact of the cam 8 with the second section 7 of an arm 5 forms a bearing contact zone.
- This displacement drive of the cam 8 in the first direction D1 is illustrated by the passage from FIG. 2 to FIG. 3 of the jaws 2.
- the actuator 9 which here is a double-acting cylinder, retracts and the cam 8 tends to move closer to the pivot axes XX' of the arms 5.
- This bringing the cam 8 closer to the pivot axes XX' of the arms 5 therefore corresponds to the first direction D1 of movement of the cam 8
- the distance D between the bearing contact zone of the cam 8 with the second section 7 of an arm 5 and the pivot axis XX' of said arm 5 varies in the direction of a reduction of this distance D.
- the cam 8 is in bearing contact with said second sections 7 of the arms 5 in the state driven in movement of the cam 8 by said actuator 9 in the second direction D2 opposite to the first direction D1.
- the jaws 2 are mounted so as to pivot in the direction of a separation of the tool holder parts 3 in the state driven in movement of the cam 8 by said actuator in the second direction D2.
- the crimping head 1 comprises a member 12 for recalling the tool holder parts 3 of the jaws 2 in the spaced position from the said tool holder parts 3, that is to say in the close position of the second sections. 7 of the arms 5.
- This member 12 for recalling the tool holder parts 3 of the jaws 2 in the spaced position from said tool holder parts 3 is a spring disposed between the second sections 7 of the arms 5. This spring tends to return the second sections 7 arms in a position close to each other to come to rest on the cam 8.
- the second section 7 of each arm 5 forms, at its part capable of coming into bearing contact with the cam 8, a surface 10 called cam surface.
- the cam surfaces 10 form between them, seen in a direction parallel to the pivot axis XX' of the arms 5, a V with the tip of the V oriented towards the pivot axes XX' of the arms 5.
- cam surfaces 10 therefore form between them surfaces converging in the direction of the pivot axes XX' of the arms.
- the cam 8 in rolling support contact with the second section 7 of each arm 5 is equipped, at each support contact zone, with at least one roller 11 rotatably mounted on the rest of the the cam 8.
- the cam 8 comprises in this case a cam body and rollers 11 .
- Each roller 11 rotates by rolling on the cam surface 10 of the arm with which the roller 11 is in rolling bearing contact during the displacement of the cam 8 along the second section 7 of the arms 5.
- the movement of the cam 8 in the first direction D1 that is to say in the direction of bringing the cam 8 closer to the pivot axes XX' of the arms 5 therefore causes, by movement at pivoting of the arms 5 around the axes XX', a rimpedement of the tool holder parts 3 of the jaws 2, that is to say a rimpedement of the first sections 6 of the arms 5 and a separation of the second sections 7 of the arms 5, while that the movement of the cam 8 in the second direction D2 opposite to the first direction D1, that is to say in the direction of a separation of the cam 8 from the axes XX 'pivot of the arms 5, allows a movement at pivoting of the arms 5 about the pivot axes XX' in the direction of a separation of the tool holder parts 3 from the jaws 2, that is to say in the direction of a separation of the first sections 6 of the arms 5 and d a rimpedement of the second sections 7 of the arms 5.
- the crimping head 1 comprises at least one clamping device 16 to allow the profiles to be assembled to be held in position.
- Said clamping device 16 comprises at least one articulated arm 17 carried by said support 15 and a presser member 18 disposed at the end of the articulated arm 17, this presser member 18 being associated with an actuating member 19, such as a cylinder, for movement of said pressing member 18 between a spaced position and a position close to the support 15.
- This pressing member 18, such as a movable stud can be positioned at least partially plumb with the inside of the centering V 13.
- This clamping device 16 ensures a vice setting of the profiles between the support 15 and the presser member 18.
- the cam 8 is therefore driven in movement by the actuator 9 for driving the movement of the cam 8 in the first direction D1, that is to say in the direction of an approximation of the cam 8 of the axes XX' pivot to allow a separation of the second sections of the arms and in parallel a bringing together of the first sections 6 of arms up to a position in which the tools 14 for cutting the jaws 2 are in contact on the profiles to be connected to the crimping point of the latter before crimping.
- the continuation of the movement of the cam 8 in the first direction with the aid of the actuator 9 for driving the movement of the cam 8 allows the cutting tools 14 to penetrate into the constituent material of the profiles and to cut a tab in the wall of each profile to be connected.
- This tongue is intended to cooperate with a bracket placed beforehand inside the angle formed by the two sections.
- the cooperation of said bracket with at least two crimping tabs provided in the wall of each profile makes it possible to secure said profiles and to maintain them in the crimping position.
- the installation shown in Figure 5, can be used to make simultaneous connections of four sections to form a frame.
- Said installation comprises four crimping heads 1 in accordance with the invention. Each of these heads 1 is placed at one of the corners of the frame to be assembled. The four heads are operated in synchronism in order to cut crimping tabs in each of the profile walls to be assembled according to the process described above.
