Core insert mechanism used for cold roll forming of car doorframe

Abstract

The invention relates to a core insert mechanism used for cold roll forming of a car doorframe. The core insert mechanism comprises a frame. The frame is provided with a guide mechanism, a core rod compacting mechanism, a doorframe compacting and fixing mechanism and a discharging mechanism. The guide mechanism is used for guiding core rods in and out of a cavity of the doorframe. The core rod compacting mechanism is used for compacting and fixing the core rods onto the guide mechanism. The doorframe compacting and fixing mechanism is used for compacting and fixing the doorframe. The discharging mechanism is used for automatic discharging of the processed doorframe. The core insert mechanism has the advantages that the special guide mechanism, the core rod compacting mechanism and the doorframe compacting and fixing mechanism are arranged, and accordingly the core rods are guaranteed to smoothly enter the cavity of the cold-rolled doorframe, difference of each section in forming process can be reduced greatly, the requirement for batch production is met, the cold-rolled doorframe with the core rods inserted is guaranteed to be smoothly extracted out by the special discharging mechanism, stability of the doorframe during discharging is increased greatly, smooth feeding is achieved, and production efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of automobile door frame processing equipment, and relates to a core insertion mechanism for cold bending forming of automobile door frames. Background technique [0002] In the production of automobile cold-formed door frame forming, it is often necessary to fill the inner cavity with soft material, and use the soft material to support the door frame during the cold-bending process, so as to facilitate cold-formed forming, and try to keep the cross-sections consistent, but fill with soft material And reuse is often troublesome, and the effect is not ideal. For the existing cold-formed door frame forming production, it is often necessary to fill the inner cavity with soft materials. Generally, two methods are used: 1. If the gap is large, use a hand plug 2. If the fit is tight, use a hammer to knock in. The above two methods have the following disadvantages. Method (1) Although the structure is simple, it ca...

If the gap is large, use a hand plug 2. If the fit is tight, use a hammer to knock in. The above two methods have the following disadvantages. Method (1) Although the structure is simple, it cannot keep the sections consistent. Method (2) When knocking There is no guarantee that no damage will be caused to the cold-formed door frame, and the work efficiency is low
