Description

Technical Field

[0001] The utility model belongs to the field of pressure riveting machines, in particular to a novel manual pressure riveting machine. Background Art

[0002] Pressure riveting is a riveting method that uses the static pressure generated by a pressure riveting machine to upset the rivet rod to form an upset head; the riveted parts have the characteristics of good surface quality, small deformation and high connection strength; therefore, in actual operation, as long as the structural processability allows, pressure riveting is preferred. The pressure riveting machine uses a punching machine equipment and a special connection mold through an instantaneous high-pressure processing process. According to the cold extrusion deformation of the plate material itself, a stress-free internal inlaid dot with a certain tensile and shear strength is formed, which can connect two or more layers of plates of different materials and thicknesses. The pressure riveting machine is divided into a manual pressure riveting machine and an automatic pressure riveting machine. The existing manual pressure riveting machine cannot adjust the distance between the pressure riveting structure and the column according to actual needs when in use. Due to the limitation of the column, the middle part of the larger workpiece cannot be processed. Therefore, we designed a manual pressure riveting machine that can adjust the distance.

When using the utility model, first rotate the screw rod 4 to adjust the distance between the base 2, the fixing block 3 and the column 1, and adjust the distance according to the size of the workpiece. After adjusting to a suitable distance, stop rotating the screw rod 4, and place the workpiece and the rivet on the lower module 11. At this time, press the pressure rod 12, and the pressure rod 12 squeezes the slide bar 7 downward. The first spring 9 is compressed, and the slide bar 7 drives the upper module 10 to move downward.

When the first horizontal plate 23 is moved out of the T-shaped groove 21, the first horizontal plate 23 is rotated 180 degrees along the axis of the vertical rod 22, and the L-shaped rod is released. Under the action of the second spring 25, the first horizontal plate 23 is moved back into the T-shaped groove 21. At this time, the L-shaped rod is pressed downward, and the L-shaped rod contacts the slide bar 7.
