Abstract

The embodiment of the invention provides a flanging mechanism. The flanging mechanism comprises a driving device and a flanging device, wherein the flanging device further comprises a first pedestal, a base plate on the first pedestal and a hollow reversing frame positioned above the first pedestal in a connected manner; a roller wheel and a first shaft are also arranged on the reversing frame, the first shaft runs through a center hole of the roller wheel and then is rotationally connected to the reversing frame; the lower part of the reversing frame is provided with a second shaft, and when the flanging device is in an operating state, the reversing frame can rotate around the second shaft; two through holes in vertical directions are formed in the reversing frame, a spring is arranged in each through hole, the upper end of each spring is connected to a nut which is used for plugging the upper part of the corresponding through hole, and the lower end of each spring is connected to the bottom of a guide pillar. The service life of the flanging mechanism provided by the embodiment of the invention can be prolonged.

Description

A kind of flange body

Technical field

The present invention relates to mechanical field, be specifically related to a kind of flange body.

Background technology

At the manufacture field of automobile and auto parts machinery, for example the manufacture field of automobile panel, often need to carry out the flange operation to covering, just need to use flange body.Fig. 1 is the structure chart of a kind of flange body of prior art, and Fig. 1 medi-spring 100 is for providing the restoring force after the driven distortion of roller.But as shown in Figure 1, in prior art, need to spring support be set in the main body both sides, thereby two springs are placed in respectively on a spring support active force that the recovery reset condition is provided.

Its shortcoming is that the first point, owing to having designed spring support, so take larger space, make flange body comparatively heavy; Second point, owing to adopting the spring return structure, after using the longer time, can cause spring free length elongated, and pulling force goes down, thereby has reduced the service life of product.

Summary of the invention

The purpose of this invention is to provide a kind of flange body, the problem that life-span is low and volume is larger existed with the flange body that solves prior art.

For achieving the above object, the embodiment of the present invention provides a kind of flange body, described flange body comprises drive unit and hemmer, wherein said hemmer further comprises the first base, is arranged on backing plate on described the first base, is connected to the hollow reversing frame of described the first base top;

Also be provided with roller and the first axle on described reversing frame, described the first axle rotatably is connected on described reversing frame through after the centre bore of described roller;

Described reversing frame bottom is provided with the second axle, and when described turning device is in running order, described reversing frame can rotate around described the second axle;

Described reversing frame inside is provided with the through hole of two vertical direction, is respectively arranged with a spring in each through hole, and described spring upper end is connected to for blocking the nut of described through hole top, and lower end is connected to the bottom of lead.

Preferably, described drive unit further comprises: the second base and be connected to drive block and the limited block on described the second base, described drive block is triangle.

Preferably, described spring is Rectangular Spring.

Preferably, the outside of described the first axle and the second axle is respectively arranged with pad.

The flange body that the embodiment of the present invention provides, be arranged on spring the inside of reversing frame, reduced the use of spring support, thereby can reduce the volume of product, make product lighter, and the damage of having avoided spring externally to cause, the service life that can improve product.

The accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structure chart of the flange body of prior art;

Fig. 2 is the structure chart of hemmer in the flange body that provides of the embodiment of the present invention;

Fig. 3 is the structure chart of drive unit in the flange body that provides of the embodiment of the present invention.

The specific embodiment

Below by drawings and Examples, technical scheme of the present invention is described in further detail.

The embodiment of the present invention provides a kind of flange body, add man-hour carrying out automobile panel, for carrying out the back work of flange processing, it comprises drive unit and hemmer, and wherein said drive unit as shown in Figure 3, comprise the second base 1, be arranged on triangle drive block 3 and limited block 2 on base 1, during use, the second base 1 is installed on the mould of top, along with mould moves down and presses down, by drive block 3, drive hemmer.

As shown in Figure 2, described hemmer comprises the first base 10, is arranged on backing plate 11 on described the first base 10, is connected to the hollow reversing frame 12 of described the first base 10 tops;

Also be provided with roller 13 and the first axle 14 on described reversing frame 12, described the first axle 14 rotatably is connected on described reversing frame 12 through after the centre bore of described roller 13;

Described reversing frame 12 bottoms are provided with the second axle 15, and when described turning device is in running order, described reversing frame 12 can rotate around described the second axle 15;

Described reversing frame 12 inside are provided with the through hole 16 (as shown in dotted portion in Fig. 2) of two vertical direction, be respectively arranged with a spring (not shown) in each through hole 16, described spring upper end is connected to for blocking the nut of described through hole 16 tops, and lower end is connected to the bottom of lead.The outside of described the first axle 14 and the second axle 15 is respectively arranged with pad.Described spring is Rectangular Spring, therefore can extend the service life of product.

The use state that state shown in Fig. 2 is product, in the time of in a state of nature, reversing frame 12 tilts about 17 ° to left direction, the drive block 3 that is positioned at top presses down, contact roller 13, compressing roller 13 drive reversing frames 12 to right-hand rotation, reach the plumbness shown in Fig. 2 around described the second axle 15.When plumbness, the spring of reversing frame 12 inside is compressed, has elastic force.After drive block 3 is removed, spring is upheld, and product is playbacked.

The flange body that the embodiment of the present invention provides, be arranged on spring the inside of reversing frame, reduced the use of spring support, thereby can reduce the volume of product, make product lighter, and the damage of having avoided spring externally to cause, the service life that can improve product.

The above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only the specific embodiment of the present invention; the protection domain be not intended to limit the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
