Abstract

The invention relates to the treatment of, ike metals by pressure and, in particular; to methods for producing links of tracks. ; Noah chain punching on crank mountains of stamping presses. The purpose of the invention is to increase the tool life and the quality of the parts produced. The punching with a burr is moved and with bore holes. It is passed to the position of the firmware, where the holes are pierced, the part of the flash is cut, and in the remaining area it is fflpy. The semifinished product is then transferred to the post-finishing treatment where the dressing is applied to the forging, and the COB from the forging is separated. 1 Z.Ps f-Ly 2il. S WITH

Description

I

The invention relates to the processing of metals by pressure and, in particular, to a method of hot forging of links of a track chain on crank mountains for stamping presses (KPPP).

The purpose of the invention is to increase the tool life and the quality of the finished parts.

Figure 1 shows the scheme tefebra; calling the blank into the product; Fig. 2 shows a stamp for receiving articles.

The method is as follows. in a way.

A steel cut blank (not shown) of square or rectangular section, of a certain mass, heated to a forging temperature within 1100-1180 ° C, is installed on the lower firing pin 1 of the first position of the multi-position tool. They are precipitated by the upper brisk 2. The metal is redistributed by the sediment by the volume of the initial cooking flow, 3 and the scale is knocked down from its surface. After the completion of the press stroke, the initial billet 3 is transferred to the lower tool 4 of the second one for hot volumetric deformation by the upper tool 5, by punching redistribute the metal over the volume of the stream and forming a splinter 7 in the plane of the press bushing the workpiece 6 is shifted to the lower tool 8 of the third position for the final

burns about the volumetric deformation of the workpiece 6 by the upper tool 9. At the same time, the first position of the draft comes for processing the second logging unit. The metal is redistributed by a champion over the volume of the stream and form a thin layer 10 along the contour-shaped blank 11 and forms basting marks 12 for piercing the holes 3. Fall on the tray to remove waste After the press is finished, press 11 shifted to the lower matrix 14 of the tool. The workpiece 17 installed in the Affix device 15 by the clamp 16 is pressed against the stream 15 of the tool matrix 14 and then the tool opponent 18 pierces the workpiece 17} removing the marks 12, the cut-outs of the circumferential part 19 located parallel to the axis of movement of the workpiece 20 of the chain. 17, in the transition zones, and at the end of the world movement, the workpiece and the next press with the top 18 use the tool on the multi-position firmware and trimming of the talted part of the 20

2-sectional cuts 1-,. The cut off fc with the aim of increasing the stability of the tool 19 and the label 12 is directed under the tool and quality of the parts, at the first cavity 22, under the effect of the stamping firmware 25 of the mold 25 to the stream of the lower matrix for cutting with a force equal to the technological force straightening, and cutting off the cutting tool 26 installed in the upper part of the multi-position tool with the cut die 26 and sending it in the cavity 28, under the action of its own weight

the forgings 29 remove the clamp 24 and the forging 29 is transferred to the finished product tray (not shown),

Claims (1)

Invention Formula 1, A method for producing parts with holes such as crawler links. fall onto the tray for disposal of waste. After the completion of the press run from the chain consisting in. much deforming the workpiece and the subsequent multi-point firmware and trimming flash, which is 25 to the brook of the lower matrix 23 for cutting with a force equal to the technological force of the dressing, and the remaining part of the multi-position tool installed by the cutting matrix 26 is cut off and guides it in the cavity 28, under the action of its own weight  fall onto the tray for disposal of waste. After the completion of the press run from the chain consisting in. much deforming the workpiece and the subsequent multi-point firmware and trimming flash, which is forging 29 remove the clamp 24 and transfer the forging 29 to the finished product tray (not shown), Invention Formula 1, A method for producing parts with holes such as crawler links. jCTBeHHoro weight,. where they fall onto the waste disposal tray (not shown). After the press stroke is completed, the pressing force 16 and the sewn workpiece 17 are relieved, the cutting position is placed on the lower 23 matrix. At this position, the workpiece 17 is pressed by a clamp 24 of the clamping device Cpus. F There is a partial trimming and splitting division, and at the trimming positions, the final separation of the remaining trimming and stamping is performed. 2, the method according to I, of which is that the scrap remaining on the stamping is separated by attaching a straightening force to the forging.
