Description

Riveting device for lock rod

Technical Field

The patent relates to the field of container manufacturing, in particular to a riveting device for a lock rod.

Background

The lock rod is one of the important parts of the container, and the annual output is huge. In the production of the container lock rod, one process is to rivet the handle by means of a riveting device after the lock rod is galvanized.

The prior art commonly used in the market at present is shown in figure 1, a hydraulic press is generally adopted to directly apply an axial acting force to a rivet through a rivet head, so that the rivet is formed by radially expanding and plastically deforming, the axial acting force applied to the rivet is large, the requirement on the plastic deformation of a material of a 304 stainless steel rivet is particularly high, the stainless steel rivet is generally required to be completely annealed to prevent the cracking phenomenon during rivet riveting, but the practical result still cannot meet the drawing requirement after riveting of a lock rod, three percent reworking of a product is caused, the reworking labor intensity is overlarge, in addition, the lock rod is too large in the direct contact part of the lock rod and a female die in the riveting process, and the lock rod is often easily touched to the ground, and the surface galvanizing quality of the lock.

In addition, in the prior art adopting rotary riveting, a spherical friction swinging mechanism is mostly adopted in the transmission scheme to drive the rivet head to bear force, and a sliding bearing is used in a transmission system, so that the defect that lithium-based grease lubricating oil must be added into the spherical surface every day, otherwise, the stressed spherical surface is damaged due to oil shortage and galling, the rivet head swinging is influenced, and the rivet head cannot be used.

The prior art has at least the following defects: (1) the axial acting force applied by the rivet head is too large, so that the rivet is easy to break; (2) the damage of a zinc coating is easily caused in the riveting process and after the riveting; (3) daily maintenance is needed every day, and the maintenance cost is too high, so that the use is inconvenient; (4) the product reworking rate is high, the lock rod reworking difficulty is high, and excessive working hours are occupied; (5) the friction resistance of the sliding bearing is too large, so that the rotating speed of the rivet head is limited, the high rotating speed and the high efficiency required by mass production cannot be realized, and the production efficiency is seriously influenced.

In view of this, it is a technical problem to be solved by those skilled in the art to design a riveting device for a lock rod, which is convenient in riveting operation, small in riveting force, high in riveting strength, easy to maintain, high in production efficiency and high in yield.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a riveting device for lock rod to concrete technical scheme can realize through following.

The utility model provides a riveting set for locking lever, including the rotatory die machine of hydraulic pressure, die frame, die fixing base, the rotatory die machine level of hydraulic pressure is fixed in the die frame, the die fixing base is fixed the die, the rotatory die machine of hydraulic pressure includes motor, transmission system, hydraulic system, rotatory die, the motor passes through the transmission system drive rotatory eccentric axial rotation of die, hydraulic system promotes rotatory die stretches out forward.

Furthermore, the transmission system directly drives the rotary riveting head to rotate through a rolling radial ball bearing and a rolling plane bearing. The basic structure of the rolling bearing consists of an inner ring, an outer ring, a rolling body and a retainer, and the working principle is that rolling friction replaces sliding friction.
