- Assembly 1 is therefore extremely compact, by motor reducer 38 being movable vertically to accompany carriage 27, and therefore only requiring an extremely straightforward transmission 57, which is also movable by motor reducer 37 and transmission 47.
- assembly 1 is also due to the relative arrangement of shafts 39, 40 and motor reducers 37, 38, and to the particular type of transmissions 47, 57, which are extremely straightforward by comprising a small number of component parts, while at the same time transmitting fairly considerable power to convert the rotary movement of shafts 39, 40 to linear movement of carriage 27.

Abstract
Description
- The present invention relates to an actuating assembly for a clinching die, in particular for clinching the peripheral edge of a vehicle window, according to the preamble of claim 1, to which the following description refers purely by way of example.
- To clinch the tabs defining the peripheral edge of a window formed in a metal sheet or metal panel, e.g. in a vehicle door or roof, clinching dies are known which are inserted through the window, and which comprise two sets of blades located at two different levels and activated to perform, respectively, a so-called pre-clinching operation followed by an actual clinching operation, each defined by a roughly 45° bend of the tabs.
- The blades are operated to move horizontally between a withdrawn position towards the centre of the window, and an extracted position facing the tabs to be clinched, and are carried by a supporting table in turn operated synchronously by two motors. One of the motors translates the clinching die vertically between two reference positions to selectively position the two sets of blades at the peripheral edge of the window, and the other motor translates the blades, in the extracted position, vertically by a work travel about each reference position, so as to bend the tabs.
- In known solutions, the motors operating the supporting table are located in fixed positions alongside the clinching die, and move the supporting table by means of respective transmissions which are extremely complex and bulky.
- Moreover, being so complex, the transmissions operating the supporting table tend to introduce errors in the positioning of the supporting table and, therefore, in the pre-clinching and clinching operations.
- It is an object of the present invention to provide an actuating assembly for a clinching die, in particular for clinching the peripheral edge of a vehicle window, designed to provide a straightforward, low-cost solution to the aforementioned problems.
- According to the present invention, there is provided an actuating assembly for a clinching die, in particular for clinching the peripheral edge of a vehicle window; the assembly comprising:
- a supporting table for supporting said clinching die and movable along a longitudinal axis; and
- two actuators, one for selectively translating said supporting table longitudinally between two reference positions, and the other for translating said supporting table longitudinally by a work travel about each said reference position;
- An embodiment of the invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a schematic cross section of a preferred embodiment of the actuating assembly for a clinching die, in particular for clinching the peripheral edge of a vehicle window, according to the present invention;
- Figures 2 and 3 show schematic cross sections of the clinching die as operated by the Figure 1 assembly, and a sequence of steps in the clinching of the peripheral edge of a vehicle window.
- Number 1 in the accompanying drawings indicates an actuating assembly for a
clinching die 2, in particular for clinching the peripheral edge of a window 4 formed in abody panel 5 of a vehicle. - In the Figure 2 example,
panel 5 is defined by a door, and comprises a sheet metalouter panel 6 terminating inwards with a number oftabs 7, which define the peripheral edge of window 4 and, before being clinched and by virtue of a previous press operation, form an angle of about 90° with the rest ofouter panel 6. - To perform the clinching operation,
door 5 is set up in a fixed position at astation 9, which houses a supportingstructure 10 for supportingouter panel 6, aclamping device 11 for clampingdoor 5, and die 2. Die 2 has avertical axis 13, extends axially throughstructure 10, projects from the top ofstructure 10 to engage window 4, and comprises a number ofblades 14 for performing a pre-clinching operation, and a number ofblades 15 for performing the actual clinching operation and located at a lower level thanblades 14. - With reference to Figures 2 and 3,
blades axis 13, between a withdrawn position towards the centre of die 2 and window 4, and an extracted position vertically facingtabs 7. - Die 2 is movable axially along
axis 13 by assembly 1, which is located beneath die 2 atstation 9. - With reference to Figure 1, assembly 1 comprises a
frame 19 in turn comprising abase plate 20 fixed atstation 9, and astructure 21 projecting upwards fromplate 20.Structure 21 comprises avertical wall 22 having aU-shaped top seat 23; two transverse vertical wings 25 (only one shown) on opposite sides ofwall 22; and aplate 26 fitted to one end of wings 25 and parallel towall 22. - Assembly 1 also comprises a substantially mushroom-shaped supporting
carriage 27 in turn comprising atubular bottom portion 28 extending alongaxis 13, and a top table 29 integral withportion 28, perpendicular toaxis 13, and defining a supporting surface to which die 2 is fixed. One of the walls, indicated 31, ofportion 28 is parallel to andfaces wall 22, has abottom seat 32, and is fitted towall 22 by a preferably recirculating-ball-type guide and slide device 33 (shown schematically).Device 33 comprises two vertical guides 34 (only one shown) spaced transversely apart and connected integrally towall 22; and two pairs of slides 35 (only one shown) connected towall 31 and which run alongguides 34. -
Carriage 27 is translated axially by adrive device 36 comprising afixed motor reducer 37 and a movable motor reducer 38 (both shown partly and schematically), which are preferably electromechanical and are located diametrically opposite with respect toaxis 13. - More specifically,
motor reducer 37 is connected integrally toframe 19, on the opposite side ofwall 22 toplate 26, andmotor reducer 38 is connected integrally toportion 28, on the opposite side ofportion 28 towall 22. -
Motor reducers respective output shafts structure 21 andportion 28 respectively to rotate about respective parallelhorizontal axes Shaft 40 comprises anintermediate portion 43 housed inportion 28, and anend 44 projecting insideseat 23; andshaft 39 comprises anend portion 45 extending axially betweenwall 22 andplate 26, throughseat 32, and beneathportion 28. - Shaft 39 drives a first connecting rod and
crank transmission 47 to translatecarriage 27, and therefore die 2, alongaxis 13 and by a travel of roughly 60 millimetres, between a lowered reference position and a raised reference position, in whichblades tabs 7 respectively. -
Transmission 47 comprises acrank disk 48 integral withportion 45 and having anaxis 49 parallel to and eccentric with respect toaxis 41; and a connectingrod 50 comprising abottom portion 51 hinged todisk 48 aboutaxis 49.Disk 48 comprises aportion 52 projecting with respect toshaft 39 and supporting aprojection 53, which projects towardsplate 26 and, asshaft 39 rotates, selectively contacts tangentially a top stop member 54 and abottom stop member 55, which are carried byplate 26 to arrestcarriage 27 in said reference positions. - With reference to Figure 1, connecting
rod 50 comprises a top end portion 56 housed inportion 28, and also forms part of a second connecting rod andcrank transmission 57 driven byshaft 40 to translatecarriage 27, and therefore die 2, back and forth alongaxis 13 by a work travel of roughly 8 millimetres about each reference position, so thatblades bend tabs 7 to perform a pre-clinching and clinching operation respectively. -
Transmission 57 comprises acrank disk 58 integral withportion 43, and which has anaxis 59 parallel to and eccentric with respect toaxis 42, and is hinged to portion 56 aboutaxis 59. - With reference to the accompanying drawings, at the start of the clinching cycle,
blades projection 53 oftransmission 47 rests againstmember 55 to keepaxis 49 in a bottom dead centre position beneathaxis 41, to keep die 2 in the lowered reference position, and so keepblades 14 at tabs 7 (Figure 2); andaxis 42 oftransmission 57 is stationary in a top dead centre position overaxis 59. -
Blades 14 are extracted (as shown by the dash line on the left-hand side ofaxis 13 in Figure 2) and are then lowered ontotabs 7 to perform the pre-clinching operation byoperating motor reducer 38 to lower table 29 and die 2 axially by the work travel (as shown by the continuous line on the right-hand side ofaxis 13 in Figure 2), whileshaft 39 remains stationary. - More specifically, as
shaft 40 rotates, the eccentricity ofdisk 58 produces relative rotation betweenaxis swings connecting rod 50 aboutaxis 49, and translatesaxis 42 into a bottom dead centre position beneathaxis 59. Asshaft 40 rotates further to moveaxis 42 into the top dead centre position overaxis 59, die 2 moves back up to detachblades 14 fromtabs 7. -
Blades 14 are then withdrawn (as shown by the dash line on the right-hand side ofaxis 13 in Figure 2), andmotor reducer 37 is operated to rotateshaft 39 and solift shaft 40,carriage 27, and die 2 alongaxis 13 into the raised reference position to change the working blades (Figure 3). More specifically, asshaft 39 rotates, the eccentricity ofdisk 48rotates axis 49 aboutaxis 41, so that connectingrod 50 swings aboutaxis 59 to bringprojection 53 into contact with member 54 in the top dead centre position ofaxis 49. - Like
blades 14,blades 15 are extracted (as shown by the dash line on the left-hand side ofaxis 13 in Figure 3) and are then lowered, to perform the clinching operation and complete the bending oftabs 7, byoperating motor reducer 38 to lower die 2 axially by the work travel (as shown by the continuous line on the right-hand side ofaxis 13 in Figure 3), whileshaft 39 remains stationary. - Once die 2 is raised by
motor reducer 38 todetach blades 15 fromtabs 7,blades 15 are withdrawn (as shown by the dash line on the right-hand side ofaxis 13 in Figure 3), and die 2 is restored to the lowered reference position, i.e. to the start condition, by operating motor reducer 37 in the opposite direction to that for raising die 2. - Assembly 1 is therefore extremely compact, by
motor reducer 38 being movable vertically to accompanycarriage 27, and therefore only requiring an extremelystraightforward transmission 57, which is also movable bymotor reducer 37 andtransmission 47. - The compactness of assembly 1 is also due to the relative arrangement of
shafts motor reducers transmissions shafts carriage 27. - The small number of component parts and connections reduces slack and wear, and therefore greatly increases the positioning precision of
carriage 27 andblades - Clearly, changes may be made to assembly 1 as described with reference to the accompanying drawings, without, however, departing from the scope of the present invention, as defined by the appended claims.
- In particular, the bending of
tabs 7 may be activated by the fixed, as opposed to the movable, motor reducer, and movement between the reference positions may be activated by the movable, as opposed to the fixed, motor reducer. - The motor reducers may differ from those shown, e.g. may comprise translating, as opposed to rotary, output shafts. The movable motor reducer may be at least partly connected to connecting
rod 50 or to any other intermediate transmission members interposed betweencarriage 27 and the fixed motor reducer, so as only to be moved during translation produced by the fixed motor reducer, and not during translation of its own making. The connecting rod and crank transmissions may also be replaced by other types, e.g. cam, lever, or screw and nut screw transmissions. - Finally, actuating assembly 1 may be used for a die other than the one shown, and for clinching the edge of parts other than those described by way of example.
