Definitions

  • the invention relates to a press for pressing sleeves, cable lugs or the like onto cables or other metallic conductors or bodies.
  • Such presses are used in particular in heavy current installation work. They have a concave-shaped upper tool into which the sleeve and the conductor located therein are inserted.
  • a cylinder is fastened to the upper tool, in which a press piston is movable, which moves a lower tool in the direction of the upper tool, thereby deforming the sleeve and, if appropriate, the conductor located therein, and thus producing the desired press connection.
  • a certain degree of deformation must be maintained and this must not be left to the operator, but must be done automatically by appropriate devices in the press.
  • the press in order to enable it to be used efficiently and safely, the press must be able to press sleeves or workpieces of different diameters without prior changeover or setup work.
  • the invention has for its object to provide a press for the purposes mentioned, which is simple and inexpensive in construction and not prone to failure, which achieves the required degree of deformation reliably and with high accuracy and which can also have the advantage of a simple change to be used as a press without a predetermined degree of deformation.
  • the shapes of the lower and upper tools should be freely selectable within wide limits, so that the final cross-sectional shape of the pressed products can be largely adapted to the requirements.
  • the invention relates to a press for pressing sleeves, cable lugs or the like with a press body for receiving an upper tool, on which a cylinder is arranged, in which a press piston serving to receive a lower tool is slidably arranged, with a coaxially displaceably arranged in the press piston Control member, which is characterized in that the control member is supported against a transmission which is connected on the one hand to the plunger and on the other hand to the cylinder and which moves the control member at a fraction of the speed of the plunger when the plunger moves in the working direction, and with the plunger is connected to a locking device which, when the lower tool touches the workpiece to be pressed, connects the control member to the plunger in such a way that the control member moves at the same speed as the plunger, and that a locking device is provided on the control member is arranged, which at a predetermined position of the plunger blocks the pressure medium flow to the working space of the cylinder.
  • the division of the cylinder into two chambers and the additional metering piston are dispensed with compared to the last-mentioned prior art.
  • the depth of penetration of the lower tool into the workpiece is determined purely mechanically and not by means of an enclosed hydraulic fluid volume, so that faulty pressing by air enclosed in the hydraulic fluid is impossible.
  • the degree of deformation independent of the workpiece diameter can be changed in a very simple manner by changing the gear ratio of the transmission, while that of the workpiece diameter. dependent degree of deformation - can be changed very easily by the location of the locking device on the control member.
  • the transmission is a lever which is articulated at one end to the cylinder and at the other end to the press piston and which supports the control member between the articulation points.
  • the transmission ratio of the transmission can be selected by removing the base of the control element from the two articulation points of the lever.
  • the articulation points of the lever are equidistant from the control element, with the result that the control element moves at the old speed of the press cylinder.
  • the lever In order to be able to use workpieces of very different diameters in the case of small cylinder diameters and to take into account the pressing path to be covered by the press cylinder after the lower tool has come into contact with the workpiece, it may be expedient to design the lever as a telescope with variable length.
  • the transmission consists of two springs arranged successively in the longitudinal direction, one of which is supported with its free end against the plunger and the other with its free end against the cylinder, while the adjacent ends of the springs against a collar arranged on the control member are supported.
  • the gear ratio of the transmission can be changed in a simple manner by changing the lengths and stiffness of the springs.
  • the springs have the same lengths and the same stiffness, which means that the control element moves at half the speed of the plunger.
  • the locking device can be designed so that it has a clamping piston which is provided with a transverse bore for the passage of the control member and which is displaceable in its longitudinal direction in a radially extending blind bore of the press piston against the pressure of a spring under the pressure of the pressure medium in the working space until a wall of its transverse bore comes into contact with the control element.
  • the locking device which is uncomplicated in its construction, ensures that the control member is carried along with the pressing piston at the same speed as soon as the lower tool attached to the pressing piston comes into contact with the workpiece.
  • their structure and arrangement allow the locking device to be deactivated in a very simple manner.
  • a bore is arranged in the plunger parallel to its longitudinal axis, which extends from the upper tool to the blind bore and into which a rod can be inserted that protrudes into the blind hole and limits the movement of the clamping piston. In this way, the contact of the clamping piston with the control member can be prevented.
  • the locking device can be a valve plate attached to the end of the control member protruding from the plunger and which cooperates with a valve seat arranged on the cylinder. This results in a particularly simple and inexpensive training of the press.
  • an actuating element for a valve located in the pressure medium supply line to the work space can be arranged on the control element and finally an actuating element for a switch located in the energy supply of a pressure medium pump can be arranged on the control element.
  • the press body is designated 1. It carries an upper tool 2 which can be interchangeably arranged in it, so that upper tools with different inner profiles can be used.
  • the lower tool interacting with the upper tool is designated by 3.
  • It is also interchangeably arranged on the plunger 4, so that lower tools of different profile shapes can also be used in this case.
  • a rod-shaped control element 5 which carries a valve plate 6 at its lower end:
  • a collar 7 is arranged on the control element 5 and is pressed against a lever 9 by a spring 8.
  • the lever 9 is pivotally mounted at one end on the plunger 4 and at the other end on a shoulder in the cylinder 10.
  • the lever 9 is designed in such a way that the control element 5 can move freely in an opening in it, but the collar 7 cannot pass through this opening.
  • the cylinder 1o has at its inlet a valve seat 11 which cooperates with the valve plate 6 to form a valve which, in the closed state, prevents the entry of hydraulic fluid into the working space 24 of the cylinder 1o.
  • the content of the cylinder 1o displaceable P resskolben 4, is sealed against the pressure chamber 24 by a seal 12 and is pressed into its rest position by a compression spring 13.
  • a radially extending blind bore 14 is arranged in the press piston 4, in which a clamping piston 14 is displaceable.
  • the clamping piston 14, as can be seen in the drawing, is provided with a transverse bore through which the control element 5 passes. It also has a seal 16 and is supported by a spring 17 against a collar 18 arranged in the blind bore 14.
  • the bore, which runs from the working space 24 to the blind bore 14, is not sealed, but rather allows the pressure medium present in the working space 24 to pass through.
  • the part of the clamping piston 15 to the left of the control element 5 in the drawing is also not guided in the blind bore 14 in a pressure-tight manner, this fit or guidance also allows the pressure medium to pass through.
  • the spring 17 is dimensioned such that the pressure rise in the working space 24 which occurs when the upper tool 3 comes into contact with the workpiece 22, 23 and which continues against the bore side of the clamping piston 15 located to the right of the control element 5 in the drawing is sufficient for the clamping piston 15 so far against the action of the spring 17 that its left side in the drawing comes to rest against the control member 5 and establishes a rigid connection between the control member 5 and the plunger 4. Then, as can be seen in Figure 2, the control member 5 with the plunger 4 is carried at the same speed until the valve plate 6 located at its lower end comes to rest on the valve seat 11 located on the cylinder 10 and the further inflow of pressure medium into the working space 24 prevented.
  • the press described in FIGS. 1 and 2 acts in such a way that a pressure medium, for example oil conveyed by a pressure pump, is first introduced into the working space 24 of the cylinder 10 through the pressure medium supply opening 25.
  • a pressure medium for example oil conveyed by a pressure pump
  • the plunger 14 and the lower tool 3 attached to it are moved against the workpiece 22, 23 located in the upper tool 2, initially until the lower tool 3 contacts the workpiece 22, 23.
  • the control member 5 is also moved in the same direction with the press piston 4, but only by the action of the lever 9 at half the speed of the press piston 4.
  • the pressure in the working space 24 rises at.
  • the equally long distances of the articulation points of the lever 9 from the control member 5 selected in the exemplary embodiment determine the degree of deformation of the workpiece 22, 23. By changing the distances, the degree of deformation can, if desired, be changed.
  • the transmission can be modified compared to the embodiment.
  • two springs can be used, which are arranged in succession in the longitudinal direction on or around the control element 5.
  • One of the springs is attached to the plunger 4 or is supported against it, the other spring is attached to the bottom of the cylinder 10 or is supported against it and both springs are attached to the collar 7 of the control member 5 or are supported against the latter . If both springs have the same lengths and the same stiffness, this has the consequence that the control member 5 moves with the plunger 4 in the same direction but at half the speed until the locking device 15 takes effect.
  • the degree of compression of the workpiece 22, 23 can be changed by changing the spring lengths and / or the spring stiffness.
  • the distance between valve plate 6 and valve seat 9 in FIG. 1 corresponds to half the distance between lower tool 3 and upper unit Stuff 2. If, under these circumstances, the distance between valve plate 6 and valve seat 11 is reduced, thinner sleeves or workpieces become weaker, ie pressed with a lower degree of deformation than thicker ones. If the distance between valve plate 6 and valve seat 11 is increased under the same circumstances, thinner workpieces or sleeves are pressed with a higher degree of deformation, that is to say pressed more than thicker ones.
  • a rod 21 arranged on a lower tool 20 serves to limit the displacement path of the clamping piston 14 in such a way that the control member 5 cannot be clamped.
  • This is necessary or expedient if the stroke of the press ram 4 after the lower tool 2o attached to it has reached the workpiece is not to be of a predetermined size, but is determined by the force of the press or by the operator.
  • the lower tools, e.g. 2o generally have a shape that differs from the lower tool 3, it is expedient to firmly connect the rod 21 to the lower tool 2o. This training avoids mistakes in handling the press.
