Examples

As shown in fig. 1 to 4, the present invention discloses a rivet press-connecting machine, which is mainly used for rivet press-connecting a plate material 10 as shown in fig. 1, wherein a plurality of press-connecting grooves 11 are formed on the surface of the plate material 10, and rivets are required to be pressed into the press-connecting grooves 11 of the plate material one by one. Of course, the rivet press may be used for other applicable purposes, and is not limited herein.

A rivet crimping machine comprises

The pressing device comprises a base 20, wherein a mounting frame 21 is arranged on the base 20, a pressing component is arranged on the mounting frame 21, the pressing component comprises a pressing cylinder 22 and a pressing head 23, a cylinder body of the pressing cylinder 22 is mounted on the mounting frame 21, a piston rod of the pressing cylinder 22 is vertically arranged, the piston rod can move up and down relative to the cylinder body, the pressing head 23 is arranged at the bottom end of the piston rod of the pressing cylinder 22, the bottom surface of the pressing head 23 is a plane, and a limit nut 24 is arranged at the top end of the piston rod of the pressing cylinder 22;

the crimping seat 30 is located below the crimping component, the crimping seat 30 comprises a fixed seat 31 and a supporting plate 32, the height of the fixed seat 31 is not lower than that of the base 20, and the supporting plate 32 is detachably mounted above the fixed seat 31.

The air cylinder is adopted to drive the crimping head 23 to crimp the rivet, so that the efficiency of rivet crimping can be effectively improved compared with manual operation; the crimping head 23 is a cylindrical part, and the bottom end of the crimping head is a plane, so that when the rivet is pressurized, stress on each part of the rivet can be more uniform, and the quality of crimping the rivet is effectively improved.

And the design of the limit nut 24 makes the piston rod of the crimping cylinder 22 limited when being pressed down, when the limit nut 24 plays a role of limiting (when the piston rod can not move down any more), the piston rod moves to the lower limit position thereof, namely the lower limit position when the piston rod is crimped with the rivet, and at this moment, the rivet of the crimping groove 11 is crimped in place just. Due to the design of the limit nut 24, the piston rod presses down the crimping rivet to move to the corresponding lower limit position at every time, the phenomenon that the plate raw material 10 is damaged due to too much downward movement of the piston rod can be effectively avoided, the condition that the rivet is not in place in crimping is avoided, and the quality of the rivet in crimping is effectively improved.

Wherein, more firm when moving for the crimping subassembly, also be simultaneously in order to make mounting bracket 21 compacter, whole volume littleer, mounting bracket 21 compares with base 20, does not extend a lot towards the lateral (if mounting bracket 21 extends a lot outwards, crimping seat 30 can directly set up under the crimping subassembly, but mounting bracket 21 is unsettled too much like this, the crimping subassembly of installing above also relatively shakiness and easily rocks, is unfavorable for the crimping quality). Therefore, the side of the base 20 close to the press-connecting seat 30 is necessarily designed to be suspended, so as to facilitate the operation of the press-connecting assembly, and the position of the press-connecting head 23 of the press-connecting assembly corresponding to the press-connecting seat 30 is closer to the edge of the press-connecting seat 30, which is not favorable for the stability of the plate material 10 during the press-connecting process, and even may cause the plate material 10 to tilt and turn over during the press-connecting process.

In order to solve the above problem, the crimping seat 30 is designed to be a structure of the fixed seat 31 and the detachable support plate 32, meanwhile, the height of the fixed seat 31 cannot be lower than that of the base 20, the area of the support plate 32 is larger than that of the top surface of the fixed seat 31, when the support plate 32 is fixed on the fixed seat 31, the support plate can cover the upper side of the base 20, so that the hanging position of the base 20 close to one side of the crimping seat 30 is also supported, so that when the plate raw material 10 is placed on the support plate 32, and the crimping head 23 crimps the rivet downwards, the plate raw material 10 can be effectively prevented from inclining. In addition, the area of the plate raw material 10 is larger, and the crimping grooves 11 are more dispersed, so that the plate raw material 10 needs to be continuously moved and changed in position during the crimping process, and the design of the supporting plate 32 provides more space for changing the position during the crimping process of the plate raw material 10, thereby further ensuring the balance of the plate raw material 10 during the crimping process.

During the use, the crimping rivet is earlier put in advance to the crimping groove 11 that plate raw materials 10 corresponds by the manual work earlier, later place plate raw materials 10 on backup pad 32, will treat the rivet of crimping and move to the below of crimping head 23, crimping cylinder 22 drive crimping head 23 downward crimping rivet can (cylinder piston rod pushes down at every turn and all moves to its lower limit position), it makes the next rivet of treating the crimping move to crimping head 23 below to change the position of plate raw materials 10 after the completion, it can to accomplish the crimping until all rivets on plate raw materials 10.

In this embodiment, the supporting plate 32 and the fixing seat 31 are fixed by bolts. Backup pad 32 is detachable design with fixing base 31, then can select different backup pads 32 according to the actual demand, and different backup pads 32 can be thickness difference, and crimping cylinder 22 piston rod pushes down when the lower limit position is definite, if plate raw materials 10 thickness is different, then need correspond the backup pad 32 of selecting different thickness.
