Definitions

  • the invention relates to an upsetting device according to the preamble of claim 1, as was known from US-A-382 632. It is already known to design the upsetting device of a device for producing wire pins with a short stroke of the upsetting tool, wherein the upsetting of the wire pin head can take place either from a short-stroke crankshaft or from a short-stroke cam disk via a compression sled.
  • the advantage here is that a longer time is available for the deformation than with long-stroke designs, which means a lower deformation speed and a smaller resistance to deformation. The result is a smoother transition during the upsetting process without changing the operating play in the coupling links and thus a low-noise machine. Compare Figures 1 and 2 of the Federal German patent application 7e, 10.p 3385D of October 1, 1948 published on August 24, 1950.
  • a disadvantage of the short stroke version is that because of the short upsetting tool path, the distance between the wire holding the jaws during the upsetting of the head and serving as an anvil and the upsetting tool when the upsetting carriage is in the retracted position is very small. If the upsetting tool and especially the clamping tools have to be replaced when the tool is worn or when the wire diameter to be processed is changed, it has so far been necessary to remove the heavy jaw box in which the clamping jaws are seated in order to remove them To be able to change tools. Compare Figure 9 (page 40) for the essay by J. Gloser: "Czechoslovak Nail Machines" on pages 34 to 43 in the magazine "Die Heavy Industry of Czechoslovakia" 12/1964.
  • the invention is therefore based on the object of providing an upsetting device in a short-stroke design in which, as a result of a change in the wire diameter to be processed or in the case of tool wear, as few as possible light device parts have to be removed in order to be able to replace the tools. Furthermore, the facility should be able to work more precisely, with less maintenance and even quieter.
  • This object is achieved on the basis of a device of the type mentioned in the introduction by the characterizing features of claim 1.
  • the upsetting tool and guide can be easily removed as a unit for carrying out the conversion work. Due to the separate arrangement of the upsetting tool and the drive slide, any reworking of the slide guide parts that may be required is possible without an adverse influence on the upsetting process, ie on the product quality.
  • the invention also relates to the use of the upsetting device according to the invention in a wire-processing machine, in particular for the production of headnails.
  • the mode of operation of the described device is as follows when it is part of the device for producing wire pins, which is partially shown in FIG. 1:
  • a feed not shown but known, pulls the wire (154) from the wire supply through a straightening device and pushes it, as shown in FIG. 1 , as much wire through the opened cutting tools (152) and into the tooth gaps of the two toothed belts (92 and 94), only the lower toothed belt (92) being drawn in in FIG. 1, as for the desired wire pin length and for shaping the Wire pin head (84) is required.
  • the cutting tools (152) which act against one another and can each sit in a lever or in a carriage, cut off the wire (154), a pyramid-shaped wire pin tip (88) being produced.
  • the intermittent drive of the pair of toothed belts (92 and 94) stops briefly. Then the drive is switched on again for a short time, thereby moving the pair of toothed belts one step further and stopping again before a new wire feed (this could also be done by a stepping gear). This happens until a cut-to-length pin blank (86) comes to rest between the clamping tools (76) of the clamping device (78) and in the middle in front of the upsetting tool (54) of the upsetting device (14).
  • the compensation is that the cutting tools (152) of the cutting device and the clamping and upsetting device (78, 14) of the device for producing wire pins (82) are arranged in a stationary manner, the different distance from the wire pin tip (88) to the upsetting tool (54) in the manufacture of a different pin length is compensated for by shifting the pin blanks (86) in their longitudinal direction within the transport path between the cutting station and the head upsetting station, as follows: The positioning of the pin blanks (86) is carried out by the two positioning tools (132 and 146) of the positioning device (116), the first tool (132) having its four working surfaces (134 to 140) for a gradual feed.
  • the step-by-step positioning takes place with each advance stroke of the slide (12).
  • the carriage (12) moves forward, i.e. when each wire pin head (84) is produced
  • the positioning tool (132) guided in the machine frame (36) is transferred to the transport device (96) via the connecting rod (110) and the rocker arm (106). Moved so that the pin blank (86) located at the time in front of the first working surface (134) of the positioning tool (132) is advanced by a certain amount.
  • the transport device (96) stands still during this process.
  • the pin blank (86) is possibly moved back a short distance from the work surface (150), as a result of which the length tolerances of the pin blanks are compensated for so that it has reached its final position, and he comes after the two transport intervals between the clamping tools (76) that exactly such a large wire end protrudes from the clamping jaws (76) as is required to form the wire pin head (84).
  • the second positioning tool (146) moves them back in two steps, in such a way that the pin blanks are first moved back from the work surface (148) and then from the work surface (150) to the final position.
  • the positioning device (116) can be dispensed with entirely if only pins of a length order are to be produced, or if no such high pin quality is required.
  • the cutting device is then arranged so that the pin blanks (86) come to rest in the transport device (96) in such a way that just such a wire end comes out of the Clamping tools (76) protrude as is required for the head production during the upsetting process.
  • the clamping jaws (76) close, they hold the pin blank (86) for the following upsetting process to produce the pin head (84).
  • the connecting rod (18) is set in motion by the (short-stroke) crank pin (24) of the drive shaft (28), which gives the carriage (12) a reciprocating movement.
  • a finished wire pin (82) is moved further out of the tool area, while a new pin blank (86) gets between the tools (54 and 76), whereupon the process begins again.
  • the finished pins (82) fall out safely via a slide at the end of the transport route without an additional ejector, or the orderly arriving finished pins can also be automatically removed and removed for magazine or other processing.
  • the upsetting tool (54) is arranged in a separate guide (48) and is not positively connected to the slide (12), the upsetting tool (54) together with the guide (48) can be removed as a unit by simply loosening the nuts of the stud bolts ( 66) can be easily removed and replaced if necessary. Furthermore, the clamping tools (76) can be replaced easily accessible after removing this unit. Another advantage of this, book-led outside of the carriage (12) Upsetting tool arrangement is its long circular guide, which extends over a relatively large part of the tool length on both sides, which ensures that the tool is supported without play and canting.
  • the upsetting pressure does not have to be absorbed by the slide (12) and its guide strips (32, 34), which would have to be replaced as a whole in the event of excessive wear.
  • the inaccuracy of the manufactured product was transferred with increasing wear of the slide and the guide parts, ie with increasing guide play, so that the machine had to be continuously monitored in order not to produce any rejects. As the lead game increased, the machine became louder and louder.
