The number, position and size of the punches 102 match those of the friction plate positioning holes 301 on the friction plate 3; the positioning pins 211 are used to position the corrugated plate 4 and the friction plate 3 during riveting; the lower template 210 is provided with a plurality of riveting punching holes 212; the number and positions of the riveting punching holes 212 match those of the friction plate rivet holes 302 on the friction plate 3; the sizes of the riveting punching holes 212 match those of the rivets 5; the number and position of the punches 102 match those of the riveting punching holes 212, so that all the rivets 5 can be used to rivet the corrugated plate 4 and the friction plate 3 together at the same time during one riveting operation.

[0022] The upper die 1 includes an upper die base 101 and thirty-six punches 102 . The upper die base 101 is fixedly installed on the upper die of the hydraulic press, and the punches 102 are fixedly installed below the upper die base 101 .

[0023] Among them, the base includes a lower die base 201, a first support plate 204 and a second support plate 206 from bottom to top. Eight support columns are fixedly arranged between the lower die base 201 and the first support plate 204. An operating space 213 is formed between the lower die base 201 and the first support plate 204, which is convenient for using the clamping mechanism on the hydraulic press working platform to clamp the lower die base 201 so that the lower die base 201 is fixed on the hydraulic press working platform. The second support plate 206 is fixedly connected to the first support plate 204 and the mounting plate 207 respectively.

[0024] The support column is threadedly fixedly connected to the lower die base 201 and the first support plate 204 by the first bolt 202 and the second bolt 203 respectively, and the mounting plate 207 is threadedly fixedly connected to the second support plate 206 and the first support plate 204 by the third bolt 205.

Then, the friction sheet 3 is placed on the corrugated sheets 4, and the positioning pins 211 are sleeved in the positioning holes 301 of the friction sheets to achieve complete positioning of the friction sheets 3. Then, 36 rivets 5 are sequentially placed in the rivet holes 302 of the friction sheets and the rivet holes 402 of the corrugated sheets, and the hydraulic press is started (the pressure value adapted to the riveting fastening force has been set). The upper die 1 drives the punch 102 to move downward. After the punch 102 contacts the rivet 5, it pushes the friction plate 3, the corrugated plate 4, and the lower template 210 to continue to move downward. After the lower end of the rivet 5 contacts the guide column 209, it rolls upward under the action of pressure to rivet the corrugated plate 4 and the friction plate 3 together. After the riveting is completed, the upper die 1 drives the punch 102 to move upward. Under the action of the compression spring 208, the lower template 210 pushes the friction plate 3 and the corrugated plate 4 that have been riveted together to move upward, completing the automatic riveting work of the entire product.

[0028] The utility model utilizes the stable output adjustable pressure of the hydraulic press when working, and can rivet the friction plate 3 and 9 corrugated plates 4 together with 36 rivets at one time, which greatly improves the work efficiency, reduces the labor intensity, and also reduces the skill requirements for the operating staff.
