Description

Bar rolling module

Technical Field

The present invention relates to a rolling module design, and more particularly to a bar rolling module capable of rapidly processing and forming a bar-shaped object from a metal wire.

Background

In the past, for the forming process of the metal bar-shaped object, a larger metal wire rod is mainly prepared, and a processing and repairing procedure is carried out according to the required size so as to gradually form the metal object into the bar-shaped object type required to be used; conventionally, the length of the metal object is required to be sufficiently longer than that of the formed rod-shaped object in a car repairing processing mode, so that a lot of waste materials are generated in the car repairing processing, the processing cost is increased, the qualified size can be effectively formed by a slow processing mode to achieve the correct size, the required rod-shaped object can be formed by continuous car repairing, and the hardness of the finished material is poor.

In view of the above, the inventor has developed a rolling machine, which performs the operation in a rolling manner, and by providing a rolling device in the rolling machine, the metal bar is gradually subjected to a rolling action force applied for a plurality of times, and a plastic deformation is generated due to the pressure, so that not only the structural density of the metal bar is changed to increase the hardness, but also the metal bar is rolled to form a desired metal wire diameter; after practical use, the rolling machine can roll the metal bar only in one side direction (i.e. up and down/left and right sides) each time the rolling machine rolls the metal bar, then, the operator needs to change the direction of the metal bar which has been rolled for the first time, and then roll again for the second or even the third time until the required size is completed, so the processing method will lead to long processing time, meanwhile, for the metal wire diameter object with special size requirement, not extra multiple machines are needed to carry out processing operation, which causes the increase of equipment cost, or after each processing procedure is finished, and then, after the rolling distance of the rolling device is continuously adjusted in a time-consuming and labor-consuming manner, another rolling processing stroke can be effectively and continuously carried out, so that the processing cost is high, the working efficiency is poor, and the improvement is needed.

SUMMERY OF THE UTILITY MODEL

Therefore, the present invention is directed to a bar rolling module, and more particularly to a rolling module for roll forming a metal bar by a one-time in-place rolling process, which has the effect of increasing the yield of processing capacity.

To achieve the above object, the present invention provides a bar rolling module installed on a rolling machine for roll-forming a desired shape of a metal wire rod into a desired shape of a metal wire rod, the bar rolling module comprising: the rolling device comprises a seat body, an opening arranged at the center of the seat body, two rolling wheels correspondingly arranged on the seat body and positioned at the opening, and a transmission set for driving the rolling wheels to rotate; wherein, the seat body is provided with a top surface for the rolling wheel and the transmission set to pivot and a bottom surface opposite to the top surface; in addition, a rolling groove in a circumferential shape is arranged on each rolling wheel corresponding to the opening, and a channel for the metal bar to pass through is formed between the two rolling grooves; and a shaping device connected with the rolling device and arranged on the rolling machine in a mode opposite to the rolling device, wherein the shaping device comprises a die holder, a through hole arranged at the center of the die holder, two rolling wheels correspondingly arranged on the die holder and positioned at the through hole, and a linkage group driving the rolling wheels to transmit, wherein the die holder is provided with a top surface for the rolling wheels and the linkage group to pivot, and a bottom surface opposite to the top surface, the two rolling wheels and the two rolling wheels are arranged on the die holder in different directions, and a rolling groove in a circumferential shape is arranged on each rolling wheel opposite to the through hole, so that a groove for the metal bar to penetrate through is formed between the two rolling grooves.

Wherein, the opening is arranged in a tapered manner from the bottom surface to the top surface, and the smaller diameter of the opening is larger than the outer diameter of the channel.

Wherein, the bottom surface of the seat body is at least provided with four embedded areas.

The through hole is arranged in a tapered manner from the bottom surface to the top surface, and the smaller diameter of the through hole is larger than the outer diameter of the channel.
