Definitions

  • the invention relates to a surface grinding machine for punching tools according to the preamble of claim 1.
  • a surface grinding machine for punching tools according to the preamble of claim 1.
  • Such a machine is JP-B-52 15 159. ge by - Service. It is used to grind, for example, ring-shaped parts, a perfect grinding being achieved in particular by the fact that the axes mentioned have been arranged in parallel at a distance from one another and both the workpiece and the tool rotate. There is no special scanning device for the surface of the workpiece to be ground or the infeed movement of the tool.
  • Stamping tools or stamps and dies can be of different lengths or heights. For this reason, the distance of the grinding wheel, for example in its highest position, from the surface of the punching tool part to be ground is rarely the same. This means that you have to adjust the grinding wheel by different amounts and this has a disadvantageous effect on the processing time. Above all, this prevents automatic grinding of the punching tool parts.
  • the object of the invention is therefore to develop a surface grinding machine of the type described in the introduction in such a way that the total time required for grinding can be reduced and the requirements for automatic grinding are met.
  • the surface grinding machine is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim.
  • the distance of the contact surface of the scanning member from the working surface of the grinding wheel is the same for all punching tools, so that with the help of the scanning member a certain “zero position” of the grinding wheel relative to the punching tool or punching tool part can be obtained quickly and easily.
  • Due to the height adjustability of the guide member it can also be brought to its starting position, regardless of the height or length of the tool part, in which it is locked when it rests on the control cam and the sensing member on the tool part.
  • the grinding tool must now be advanced via the infeed control curve until it hits the stamping tool part. Then there is a further infeed by the amount by which the punching tool part is to be ground.
  • a particularly preferred embodiment of the invention provides that the scanning member is rotatably mounted on an adjustable carrier for the grinding wheel. It can be easily swiveled into the infeed area of the grinding wheel and swiveled out again after alignment and before grinding.
  • a further embodiment of the invention results from claim 4.
  • a further variant of the invention provides that the guide member is spring-loaded against the control cam by means of a spring, the spring supporting the lowering of the guide member from its own weight.
  • the control cam can be displaced in a very advantageous manner by means of a hydraulic feed device.
  • the infeed movement and the shape of the control curve determine the time required and the degree of grinding.
  • the control curve expediently has a steeply sloping section and a flatter section, the guide member first scanning the steeper section. Therefore, the grinding wheel is quickly lowered first. It is particularly advantageous that the height of the steeper section corresponds approximately to the height of the scanning element, measured in the feed direction. So there is first a rapid lowering by the height of the scanning member, the grinding wheel then already being directly above the surface of the punching tool part to be ground. The flatter section then gently feeds in until the grinding wheel hits the workpiece and at the same time infeeds to grind off the punching tool part by the desired amount.
  • the punching tool can be inserted into a receptacle of a plate of the punching workpiece clamping device which can be pivoted and locked about an axis perpendicular to the axis of rotation of the grinding wheel. With a punch, the surface to be ground can be brought into a parallel position to the grinding surface of the grinding wheel.
  • the surface grinding machine consists of a base frame 5 in which two guide columns 4 are connected, which are connected to one another by a crosshead 6.
  • a clamping sleeve 26 is non-displaceably but rotatably mounted in the carrier 3, and it can be pivoted by means of a scanning lever 21.
  • a guide member 24 is also rotatable in the clamping sleeve 26, but is additionally longitudinally displaceable. This has a guide roller 25 at its lower end, which is supported on a control cam 23 and is pressed against it by means of a spring 28.
  • the control cam 23 can be displaced relative to the guide member 24 by a hydraulic feed device 27.
  • a clamping device 11 with its axis 19 is rotatably mounted in a drive 20, the axis 19 running parallel to the axis 8 of the grinding wheel 2 at a distance.
  • the clamping device 11 is in turn provided with a plate 12 which is pivotably mounted in receiving bores 13.
  • a support screw 18 is provided which pushes a cylinder 17 under the plate 12 until the desired angular position of this plate is reached.
  • an impression screw 16 is additionally provided.
  • the scanning lever 21 is first pivoted into the working area of the grinding wheel 2 and the carrier 3 is moved downwards until the scanning lever 21 rests on the workpiece 9. The scanning lever 21 is then pivoted out of the work area. He takes the clamping sleeve 26 with him and moves it into its clamping position, so that the guide member 24 is firmly connected to the carrier 3.
  • the control cam 23 is provided with a steeply falling section 29, which corresponds to the distance between the grinding wheel 2 and the underside of the scanning lever 21. The grinding wheel 2 is thus very quickly lowered onto the surface to be ground, which is followed by a flatter slope section 30 which corresponds to the normal working movement.
  • the clamping device 11 rotates, so that the undesired grinding in of grooves or the like. is omitted.
  • the scanning lever is again pivoted into the working area of the grinding wheel 2, the clamping sleeve 26 loosening and the guide member 24 being released for re-adjustment.
