Definitions
- the present invention relates to a hand-operated press with a shaft coupled to an actuator whose operation is converted into a lifting movement of a press ram coupled to the shaft, and thus in a change in a relative position of the press ram, and with a coupling for interrupting a power flow between the actuator and the press ram.
- Such a hand-operated press is known from the German patent DE 102 23 153 Cl.
- the invention further relates to a method for protecting a hand-operated press against overload or for canceling a satisfactorily performed pressing operation.
- the manual press of DE 102 23 153 C1 relates to a press in which a return stroke lock, as e.g. is known from DE 199 59 627 Al, is implemented electronically.
- Hand-operated presses of the type described above are commonly used in chord workstations. Since the effort of manually pressing the press increases toward the end of the press stroke, some operators tend to expend too much force and thereby poorly work or even damage the workpieces being compacted.
- a press ram of the press is formed as a force transducer.
- the force transducer has a force measuring system, such as e.g. a strain gauge (DMS), integrated.
- DMS strain gauge
- the DMS is in communication with a control device of the press, which in turn is, for example, connected to a rotary encoder in order to detect the angle of rotation of the actuating lever, and thus the path.
- the control device evaluates the acquired data to be able to carry out the above-mentioned distinction between good and bad parts after the pressing process.
- the press can automatically switch off while the bad part is still in the press. This is also done at the initiative of the controller.
- the force is recorded as a function of the path in order to be able to carry out a quality assessment after a completed pressing operation (good / bad). Since the pressing process is carried out manually, each pressing operation is performed with different force. The result of this is that workpieces to be pressed are already sufficiently "good” with one another before reaching a mechanical end position of the press ram, or that they are only sufficiently available in the end position to be able to stop before reaching the (mechanical) end position.
- the invention is therefore the object of developing a hand-operated press of the type mentioned in such a way that the described problems are avoided.
- a hand-operated press is to be provided, in the permissible overloads to a predetermined Limit can be limited and a force sensor is protected against overloads. Furthermore, when prematurely achieved desired pressing force of the pressing process can be canceled prematurely. "Bad" grouting should be avoided.
- this object is achieved in that the shaft is formed at least in two parts, namely at least with an input shaft and an output shaft, and that the coupling is arranged such that it the input shaft and the output shaft in dependence from the pressing force and / or the relative position of the press ram from each other.
- the shaft according to the invention in contrast to the prior art is formed in two parts, opened differently than before, the possibility of interrupting the power flow between the actuator and the press ram arbitrarily, regardless of the actual operation of the actuator.
- it has hitherto been known only to decelerate or fix a one-part shaft when an error occurs, in particular if the return stroke is initiated prematurely.
- the power flow between the press ram and the operating lever can be interrupted at any time by the coupling in which the shafts are separated from each other.
- a set pressing force exerted the waves can - depending on this event - separate. If an inadmissibly high pressing force is exerted during a pressing process, which could damage a force sensor or result in "badly" compressed workpieces, the waves can also be separated from one another, depending on these events.
- a sensor for detecting the pressing force and / or a sensor for detecting the relative position of the press ram is or are provided.
- a force measuring system of the press can be protected against overload. If only one sensor is provided for detecting the relative position of the press ram, it can be inferred from the distance traveled which pressing force was exerted, provided that all further parameters required for this purpose, such as, e.g. Translation of the lever movement in press stroke, properties of the workpiece to be pressed, etc., are known.
- both sensors are used in combination, this enables the recording of a force-displacement curve for each pressing process, so that a good / bad distinction can already be made during the pressing process.
- a corresponding control device is provided for this purpose, which is coupled to the first and / or the second sensor and to the clutch in order to output corresponding coupling signals to the clutch.
- the controller senses the force sensor (s) to output clutch signals to the clutch in response to signals output from the sensors.
- the control device preferably outputs a clutch signal according to which the clutch remains closed when the detected pressing force or the relative position of the press ram is less than a predetermined limit.
- the control device may output a clutch signal for opening the clutch if the pressing force or the relative position of the press ram is greater than or equal to a predetermined limit value.
- the limit value may either be a maximum allowable pressing force at which a force sensor is not damaged, and / or may be a minimum pressing stroke to be achieved in order to obtain a "good" pressing of the workpieces.
- the control device has in particular means for determining whether a predetermined pressing force limit is exceeded or whether a set pressing force is reached. If the limit is exceeded, a signal to open the clutch is output. Thus, the power flow between the actuator and press ram is interrupted.
- the manually operated press further comprises a lift stop for fixing the input shaft, wherein the lift stop in particular comprises a brake disc and a brake magnet.
- the actuating lever is fixedly connected to the input shaft, so that a locking of the input shaft results in a locking of the actuating lever.
- the brake disc in the form of a brake disc, which cooperates with a brake magnet, the brake disc is preferably rotatably connected to the input shaft and the brake magnet is spatially fixed to the press. Since it is in this case in the Hubsperre to an electrically operated braking device, the braking device can also be controlled by the above-mentioned control device by appropriate signals are sent from the control device to the Hubsperre or their elements. Furthermore, it is preferred if a third sensor for detecting the relative position of the input shaft is provided, wherein the brake disk can be designed such that the third sensor detects the relative position in cooperation with the brake disk.
- a signal can be generated according to which the clutch is closed, provided that the actuator is in its corresponding starting position.
- the starting position can be detected by means of the brake disc or a brake disc flange, which is non-rotatably connected to the input shaft and thus also connected to the actuating member. This always ensures that the power flow is only established between the actuating lever and the press ram when the operating lever is in its initial position. This ensures that the path traversable by the actuating lever can carry out the pressing stroke required to achieve a satisfactory pressing operation.
- the clutch is closed only when the press ram is in its initial position.
- a restoring device in particular a spring, which is coupled to the input shaft.
- the actuating member is a hand lever
- the input shaft is an inner hand lever shaft
- the output shaft is an outer hollow shaft
- the hand-operated press builds short, since the input shaft is an inner shaft which is arranged coaxially with the outer hollow shaft.
- the second sensor may be a linear incremental displacement measuring system that detects path markers coupled to the press ram.
- the two shafts are additionally positively connected to each other by the coupling in order to implement the lifting movement. Due to the additional positive connection, a mechanical overload protection can be realized with which spontaneously occurring overloads can be intercepted with (very) high intensity before they destroy a force sensor.
- a toothing with detent position is preferably used, which is designed such that it opens automatically from a closed state at a vor ⁇ sti ⁇ mtmten torque which is exerted via the actuating member.
- the detent position is preferably reached when the waves are in their respective starting position.
- Figure 1 is a highly schematic side view (partially broken away) of an embodiment of a hand-operated press according to the invention.
- Fig. 2 is a latching teeth of a first and second shaft portion according to the present invention.
- FIG. 3 shows a schematic balance of forces at the location of the toothing according to FIG. 2.
- reference numeral 10 designates a hand-operated press of basically known type.
- the press 10 has a base part 12, which stands on a suitable substrate, for example. A workbench. From the base part 12, supports 14 lead upwards to a head part 16, which is also referred to as a slide, since the head part 16 is adjustable depending on the desired stroke in the direction of the supports 14. Laterally on the head part 16, an actuating lever 18 is mounted, which is connected to a mounted in bearings 20 in the slide 16 shaft 22. The shaft 22 can be rotated by means of the actuating lever 18 about its axis 24, as indicated by an arrow 26, wherein in Fig. 1, the initial position of the lever 18 is shown.
- a very schematically indicated gear 28 is provided, which is a pinion rack arrangement in the simplest case. This arrangement serves to implement the rotational movement of the shaft 22 in a direction indicated by the arrow 30 vertical lifting movement of a press ram 32.
- the lower end surface 34 of the press ram 32 sets in a pressing operation on an upper workpiece 36 of a pair of Workpieces 36, 38, which are to be pressed together.
- the press 10 has a brake disk 40, which is non-rotatably connected to the shaft 22.
- a second disc 42 is arranged, which is designed as a ring, so that the shaft 22 can be passed through the second disc 42.
- the second disc 42 is rigidly connected to the slider 16, and is therefore hereinafter referred to as space-fixed.
- a brake magnet is referred to, which is electrically connected to an electronic control unit 46.
- the electronic control unit 46 can be supplied via inputs 48 control signals from the outside, for example. From a numerical control unit in order to realize the disclosed in DE 102 23 153 Cl electronic remindhubsperre. This function is also possible with the present press 10. For further details, reference is made to DE 102 23 153 C1.
- the existing from the elements 40, 42 and 44 Hubsperre is characterized essentially by the magnetic coupling effect of the electromagnet 44, which exerts this on the clutch plates 40 and 42.
- this "magnetic brake” can also be realized by a pneumatic or hydraulic brake, which connects the two discs 40 and 42 non-positively to prevent rotation of the shaft 22 about its axis 24.
- the press ram 32 may be provided with a force sensor 49, with which a respective acting pressing force can be detected can.
- the force sensor 49 is also connected to the electronic control unit 46.
- the press ram 32 can serve as a force transducer for an integrated strain gauge (DMS).
- DMS integrated strain gauge
- the sensor 49 could also be arranged at a different location, for example in the base part 12.
- the press 10 is of conventional design.
- the press 10 has a second (outer) hollow shaft 50, which is mounted coaxially with the shaft 22.
- the first shaft 22 will be referred to hereinafter as the inner hand lever shaft, since it is passed through the outer hollow shaft 50.
- the outer hollow shaft 50 is directly connected to a gear or provided with a pinion to realize the designated 28 gearbox.
- the press ram 32 has a corresponding toothing 52, which meshes with the pinion or the toothed wheel of the outer hollow shaft 50.
- the teeth of the hollow shaft 50 and the press ram 32 engage directly in one another. However, other gear elements could be interposed therebetween.
- the outer hollow shaft 50 can be positively and / or positively connected to the inner hand lever shaft 22 with a preferably electromagnetic clutch 54.
- the electromagnetic clutch 54 is also connected to the controller 46.
- the inner hand lever shaft 22 represents an input shaft, which can be coupled by means of the coupling 54 to an output shaft, which is realized in the present example of FIG. 1 by the outer hollow shaft 50.
- the relative position of the hand lever shaft 22 can be determined.
- the sensor 56 may also be connected to the control unit 46. Since the actuating lever 18 (like the disk 40) is firmly connected to the shaft 22, conclusions about the position of the lever 18 can thus also be drawn.
- the control unit 46 If it is determined that both the hand lever shaft 22 and the press ram are in their respective starting positions, from which a pressing operation can be started, the control unit 46 outputs a signal to the clutch 54, so that the clutch 54 closes, ie the inner Shaft 22 and the outer hollow shaft 50 are at least non-positively with each other connected. A power flow between the lever 18 and the press ram 32 is thus possible.
- the lever 18 is rotated in the direction of the arrow 26 in order to press the workpieces 36, 38 together.
- the lever 18, and thus also the press ram 32 eventually reaches its (electronic or mechanical) end position.
- the mechanical end position is reached when the press ram has passed through the maximum possible pressing stroke or the lever 18 is moved against a corresponding mechanical stop.
- the electronic limit position is reached when either the lever 18 has been rotated by a predetermined angle or when the press ram 32 has traveled a predetermined (stroke) way.
- the electronic limit position could be detected on the one hand by the sensor 56 by the brake disk 40, e.g. in a region corresponding to the end position is designed such that the space-fixed sensor 56 can detect the end position.
- the brake disk 40 may be formed in this area in the axial direction 24 more or less massive.
- the electronic end position can also be defined in such a way that a set pressing force (depending on the path of the press ram 32) has been achieved, ie, workpieces to be pressed have been compressed sufficiently "well.”
- a displacement measuring system 58 can be provided, which is shown schematically in FIG through a dashed line is shown. The displacement measuring system 58 detects path markings 59 coupled to the press ram 32.
- This additional displacement measuring system 58 could be realized in the form of a linear incremental measuring system, e.g. has a resolution of 5 microns.
- the path markings 59 can be scanned with the aid of a measuring head, which is preferably arranged in the head part 16 and is likewise connected to the control unit 46.
- the brake disk 40 may be connected to a return device, in particular a spring (not shown).
- the spring is then connected to the space-fixed head part 16. In the initial position, this spring is biased. In the final position, it is so tense that, should the operator the Release lever 18, the lever 18 is automatically returned to its corresponding starting position. For this purpose, the clutch 54 should be open.
- the clutch 54 can be opened before reaching the end position of the pressing operation. In this case, the power flow between the lever 18 and the press ram 32 is interrupted. The force can no longer act on the force sensor 49. The force sensor 49 is thus protected against overload.
- Controller 46 may include, for example, a suitably prepared microprocessor, which is determined by controller 46 to be "good” based on a force-displacement measurement are, interrupts the controller 46 by a corresponding signal to the clutch 54, the power flow between the lever 18 and the plunger 32nd In this case, the displacement measurement preferably takes place via the linear incremental displacement measuring system 58.
- a pressing operation can also be stopped alone depending on the relative position of the press ram 32, without actually measuring the pressing force.
- the force-displacement characteristic of the press is known, so that it can be determined solely on the basis of the stroke, if or when a "good" compression was achieved.
- the braking device 40, 42, 44 is preferably actuated first.
- the force sensor 49 detects the pressure exerted on the lever 18 pressing force; the detected pressing force is sampled by the controller 46 at predetermined intervals; Subsequently, the control unit 46 determines whether an impermissibly high pressing force is present, which could damage the force sensor 49, for example by determining whether the detected pressing force is greater than or equal to a predetermined limit, or when a "good" compression of the workpieces 36, 38th If the detected pressing force exceeds the predetermined limit value or if a set pressing force is achieved, the control unit 46 preferably outputs a signal to the braking device 40, 42, 44 first, in order to make the movement of the lever 18 more or less abruptly stop, then the controller 46 outputs a clutch signal to the clutch 54 to apply the clutch 54 to open; the coupling 54 opens; the power flow between the lever 18 and the press ram 32 is thus interrupted; Optionally, the brake can be released again.
- the lever 18 can be moved to the mechanical stop, but without being in frictional connection with the press ram 32, so that the risk of damage to the force sensor 49 is excluded. Or the operator has already released the lever 18. If the operator has already released the operating lever 18 and the above-mentioned restoring device between the brake disk 40 and the head part 16 is provided, the lever 18 automatically returns to its original position.
- the coupling 54 When the press 10 is switched off, there is preferably no connection between the lever 18 and the press ram 32, which results in increased process reliability.
- the coupling 54 For a connection to be established, the coupling 54 must first be energized.
- the clutch 54 could work in exactly the opposite way, ie the clutch 54 could also be closed in the non-activated state, in which case the controller 46 interrupts the connection first before a pressing operation can be performed and then the aforementioned check the starting position.
- the controller 46 interrupts the connection first before a pressing operation can be performed and then the aforementioned check the starting position.
- a rack meshes with a pinion or a gear could also be a planetary gear, worm gear, chain drive, belt drive, bevel gear, a toggle, a shoe lever, a hydraulic transmission o. ⁇ . be used.
- the inner hand lever shaft 22 and the outer hollow shaft 50 are not only frictionally, but also positively connected to each other.
- FIG. 2 shows a highly schematic sectional view perpendicular to a coupling surface between the inner hand lever shaft 22 and the outer hollow shaft 50.
- the plane of the drawing of FIG. 2 corresponds to the plane which is perpendicular to the plane of the drawing of FIG. 2 with detent position preferably comprises a single (detent) tooth 62, which is here formed with the outer hollow shaft 50, and a corresponding recess 64 in the inner hand lever shaft 22.
- Fig. 2 illustrates a state in which the coupling 54 (see Fig. 1) is open, so that the shafts 22 and 50 could be freely rotated against each other. Should the clutch 54 close, the shafts 22 and 50 move relative to each other along the axis 24 so that the tooth 62 engages the recess 64.
- tooth 62 could alternatively also be formed with the inner hand lever shaft 22 and the recess 64 with the outer hollow shaft 50.
- Tooth pairing can also be provided a plurality of pairs 62, 64.
- embodiments with only one (latching) tooth are preferred, as will be explained below.
- the pair of teeth 60 may additionally be used to set the initial position of the press ram 32. This means that only when the shafts 22 and 50 are properly aligned, i. when the hollow shaft 50, and thus also the press ram 32, is in its initial position, the tooth 62 and the recess 64 can engage with each other. The press ram 32 is not (yet) in its initial position, no coupling between the shafts 22 and 50 is possible.
- a magnetic force F M (Fig. 3) is required, for example, the outer hollow shaft 50 or its tooth 62 in the direction of the inner hollow shaft 22 and its recess 64th to move.
- the (closing) force F M of the coupling magnet 54 can be decomposed with the aid of a force parallelogram into the two force components F E and F 31 , where F E represents the force of incidence acting along the imaginary line 66 and F 51 represents the force acting perpendicular to the tooth flank.
- the rotational force F D can in turn be divided into two force components F A and F s2 , where F A represents the decoupling force and F x2 represents the force acting perpendicular to the gearing edge.
- the decoupling force component F A is smaller than the coupling-in component F E.
- the rotational force F D will abruptly increase, which results in an increase in the outcoupling force F A acting.
- the force component F A greater than the force component F E then there is an opening of the toothing 60, although the clutch 54 is closed or not yet open.
- the force at which the toothing 60 opens automatically depends on their sizes, in particular the flank angle ⁇ .
- the clutch 54 then acts as a mechanical overload clutch.
- gearing e.g. also rolls or similar be used.
