Abstract
The utility model discloses a kind of screw nut hydraulic riveting equipment, comprise apparatus body, described apparatus body is made up of gas-liquid power-increasing cylinder, displacement transducer and cylinder block set, institute's displacement sensors is positioned at gas-liquid power-increasing cylinder side, be provided with riveting die set and pressure sensor below described gas-liquid power-increasing cylinder and displacement transducer, described riveting die set and pressure sensor side are provided with corresponding electron pressure control system and line pressure shift monitoring system; This screw nut hydraulic riveting equipment, by hydraulic efficiency riveting nut, improves the rivet force of nut and the stability of riveting quality, reduces the input of cost simultaneously.
Description
Technical field
The utility model relates to a kind of screw nut hydraulic riveting equipment.
Background technology
Consult shown in Fig. 1, this product forms total member by a stamping parts and 4 riveting nuts, and the peel strength of riveted joint back nut is greater than 685N, and torsional strength is greater than 2.9N.m.
Riveting method in current industry: punching type riveting nut, constant pressure and height is provided by mechanical stamping lathe, nut is pressed into sheet metal component, but there is following problem: 1) tradition adopts punching type mould to carry out riveting nut, stamping machine can only provide constant pressure and height in the course of the work, when the thickness of nut or sheet material occurs that deviation is, be easy to cause nut riveting power not enough, as shown in Figure 2; 2) traditional punching type mould riveting nut, when aperture or riveting nut riveted joint spot size generation deviation, is difficult to find these deviations, and easily brings rivet force not enough by these deviations, as shown in Figure 3 in riveting process; 3) conventional ram-type mould riveted joint, each product all needs to make mould, and the volume of mould is comparatively large, and die cost is high, and the energy consumption of the every jig frequency of punch press is higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of by hydraulic efficiency riveting nut, improves the rivet force of nut and the stability of riveting quality, reduces the screw nut hydraulic riveting equipment of the input of cost simultaneously.
For solving the problem, the utility model adopts following technical scheme:
A kind of screw nut hydraulic riveting equipment, comprise apparatus body, described apparatus body is made up of gas-liquid power-increasing cylinder, displacement transducer and cylinder block set, institute's displacement sensors is positioned at gas-liquid power-increasing cylinder side, be provided with riveting die set and pressure sensor below described gas-liquid power-increasing cylinder and displacement transducer, described riveting die set and pressure sensor side are provided with corresponding electron pressure control system and line pressure shift monitoring system.
As preferably, described gas-liquid power-increasing cylinder is Q-S type gas-liquid power-increasing cylinder.
As preferably, described riveting die set includes plate location counterdie, nut location counterdie and riveted joint patrix.
As preferably, arrange in pairs or groups bottom described apparatus body and have floor push.
Operation principle:
1) provide rivet force by pneumohydraulic pressure-cylinder, will nut be pressed in the hole of sheet material, send localized metallic flowing under the effect of simultaneously sheet material just pressure, the riveted joint that metal flows into nut connects overhead kick region.
2) starting stage patrix rapid movement under the thrust of pneumohydraulic pressure-cylinder, during mold contact workpiece, namely gas-liquid power-increasing cylinder transfers force-stroke to automatically, the hydraulic oil produced by gas-liquid pressure-boosting drives mold, rivet, simultaneity factor force-stroke self-locking (now unclamp floor push, patrix is return not).When work stamping press reaches setting value (corresponding operating oil pressure reaches the setting value of oil pressure relay), when workpiece quality of connection is qualified, oil pressure relay action, controls the automatic return of mold; If stamping press does not reach setting requirement, when workpiece press-fits off quality, mold then can not return automatically, now needs to press brake hard button, forces its return, and remind operator to check reason thus, thus ensure crudy.
3) the pressure and displacement transducer signal on forcing press is arranged on, by being presented on pressure assembling display after computer disposal, can the power-displacement function curve of monitor force assembling process continuously, detect press-in quality by the inspection window that presets (contact, penetrate, by and final mean annual increment movement/final pressure) and anomaly analysis is provided.
The beneficial effects of the utility model are: versatility is high, and the riveted joint of applicable existing all riveting nuts is produced; The mode of depended on pressure guarantees nut riveting quality, not because of nut and sheet material thickness minor variations and affect riveting intensity quality; When riveted joint pressure reach setting value be just meet once riveted joint stroke terminate; In riveting process, monitored by the line pressure shift in each interval, find the product of all riveting quality exceptions, and do not need to implement destructive inspection, and can not occur spot-check less than situation.
