Abstract

The invention relates to a rolling tool for a rolled piece of a reed of a plate spring, which belongs to the field of manufacturing equipment of automobile parts and comprises a worktable (1). The rolling tool is characterized in that a rolling device is fixed at the side edge of the worktable (1) and comprises a rolling module (2), a pin roll (7), a swing mechanism and a vertical column (8). One end of the rolling module (2) is fixed on the worktable (1), and the other end of the rolling module (2) extends out of one end of the worktable and is in rotary connection with the swing mechanism through the pin roll (7). The rolling module (2) is a rectangle with an arced end. A semicircular groove is arranged at the inner side of the arc of the end part. The vertical column (8) is vertically fixed inside the semicircular groove. According to the rolling tool for the rolled piece of the reed of the plate spring, the reed can be rolled, so that the reed can have arc-shaped angle, and the rolling to the reed that cannot be completed by press punching can be realized, and the rolling tool is convenient and rapid to use and more economical and practical.

Description

A kind of leaf spring reed grasswort is rolled up curved frock

Technical field

A kind of leaf spring reed grasswort is rolled up curved frock, belongs to auto parts and components manufacturing equipment field, is specifically related to a kind of leaf springs of car manufacture reed grasswort and rolls up curved frock.

Background technology

The leaf springs of car manufacturer in existing stage is to utilize Spring Eye Machine to roll for the grasswort of leaf spring reed mostly, general arc angle requires to use punch press compressing again, the grasswort that this kind of method can meet most of leaf spring reed is rolled up curved requirement, but some company is comparatively special with respect to damper position for the leaf spring installation site of light bus, this kind of leaf spring most end a slice reed need to be with grasswort and have certain arc angle to meet mounting shock absorber status requirement, utilizes the punch press drawing method of prior art to carry out grasswort volume to this kind of reed curved because arc angle is special.

Summary of the invention

The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide one can make leaf spring reed grasswort with certain arc angle, easy to use fast, more practical leaf spring reed grasswort rolls up curved frock.

The technical solution adopted for the present invention to solve the technical problems is: this leaf spring reed grasswort is rolled up curved frock, comprise workbench, it is characterized in that: on described workbench side, be fixed with volume bending apparatus, described volume bending apparatus comprises the curved module of volume, bearing pin, swing mechanism and column, rolling up curved module one end is fixed on workbench, one end that the other end stretches out workbench is rotationally connected by bearing pin and swing mechanism, roll up the cuboid that curved module is end arc, arc inner side, end has semi-circular groove, and column is vertically fixed in semi-circular groove.Bending spring sheet to be rolled up is fixed in the curved module of volume by column, and it is curved that pendulum rotating actuation mechanism coordinates the curved module of volume to complete reed volume.

Described swing mechanism comprises U-iron piece and swing arm, and the front upper end of U-iron piece is provided with the hole that bearing pin is installed, and U-iron piece outside arranges groove with column corresponding section, and swing arm is arranged on U-iron piece one end.Drive U-iron piece to rotate by pendulum rotating lever, curved to compress reed and to complete volume.

The curved module of described volume is fixed on workbench by the set bolt on top.

In described U-iron piece, vertically run through a mandrel is installed, mandrel overcoat has roller, in U-iron piece one end vertical spindle, fishbolt is installed.Fishbolt can be adjusted the clamping force of mandrel, and roller rolls near reed and on reed, makes reed complete volume curved.

Compared with prior art, leaf spring reed grasswort of the present invention is rolled up the beneficial effect that curved frock has and is:

1, can carry out easily and fast reed rolls up curved, meet Production requirement: the curved module of volume and swing mechanism are set, and can roll up easily curved to reed by pendulum rotating actuation mechanism, make grasswort with there being arc angle, can complete punch press and suppress the curved operation of volume that cannot complete, fast and easy, ensures to produce and can carry out smoothly;

2, simplicity of design, practicality, the reed volume that is applicable to particular/special requirement is curved: whole tool structure is simple, and floor space is little, has effectively saved usage space, and the curved operation of volume of the reed with particular/special requirement of applicable negligible amounts, and small investment is more practical.

Fig. 1～3rd, leaf spring reed grasswort of the present invention is rolled up the most preferred embodiment of curved frock, and below in conjunction with accompanying drawing 1～5, the present invention will be further described:

Detailed description of the invention

With reference to accompanying drawing 1～2: this leaf spring reed grasswort is rolled up curved frock, comprise workbench 1, on workbench 1 side, be fixed with volume bending apparatus, volume bending apparatus comprises the curved module 2 of volume, bearing pin 7, swing mechanism and column 8, rolling up curved module 2 one end is fixed on workbench 1 by the set bolt 6 on top, one end that the other end stretches out workbench is rotationally connected by bearing pin 7 and swing mechanism, roll up the cuboid that curved module 2 is end arc, arc inner side, end has semi-circular groove, column 8 is vertically fixed in semi-circular groove, bending spring sheet to be rolled up is fixed in the curved module 2 of volume by column 8, it is curved that pendulum rotating actuation mechanism coordinates the curved module 2 of volume to complete reed volume.

Swing mechanism comprises U-iron piece 3 and swing arm 4, and the front upper end of U-iron piece 3 is provided with the hole that bearing pin 7 is installed, and U-iron piece 3 outsides and column 8 corresponding sections arrange groove, and swing arm 4 is arranged on U-iron piece 3 one end.Pendulum rotating lever 4 also drives U-iron piece 3 to rotate, curved to compress reed and to complete volume.

Interior vertically running through of U-iron piece 3 installed a mandrel 9, and mandrel 9 overcoats have roller 5, in U-iron piece 3 one end vertical spindle 9, fishbolt 10 are installed.Fishbolt 10 can be adjusted the clamping force of mandrel 9, and roller 5 rolls near reed and on reed, makes reed complete volume curved.

The course of work is as follows:

As shown in Figure 4, bending spring sheet 11 to be rolled up is the reed of one end with grasswort.With reference to Fig. 3: treat volume bending spring sheet 11 and roll up when curved, need first heat reed, by the grasswort borehole jack of bending spring sheet 11 to be rolled up after heating on column 8, utilization adds long lever pendulum rotating lever 4 and drives U-iron piece 3 to rotate, in the time turning to roller 5 in U-iron piece 3 and compress reed, be rotated further U-iron piece 3, bending spring sheet 11 now to be rolled up is squeezed and is rotated further along the end arc of the curved module 2 of volume, until it is complete to roll to forming.In the curved process of volume, roller 5 carries out rotation simultaneously.As shown in Figure 5, roll up after curved completing, reed forms final form, end-of-job.

Utilize this leaf spring reed grasswort roll up reed that curved frock makes with grasswort and have arc angle can meet mounting shock absorber status requirement, complete punch press and suppressed the work that cannot complete, the technology that is conducive to parts industry improves, and has very big economic and social benefit.

The above, be only preferred embodiment of the present invention, is not the restriction of the present invention being made to other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
