Description

Automatic cutting and bending machine

Technical Field

The utility model relates to a metal processing apparatus belongs to metal sheet processing technology field.

In particular to the technical field of automatic bending and cutting.

Background

The present plate bending cutting machine used in the market (including domestic and foreign) can be divided into two main types, one of them includes a feeding device, a cutting device, a power device, a bending device, a conveying device and a material receiving device, all the devices are operated mutually, in which the feeding device and the cutting device are set at the front end of the bending device, and the feeding device is used for setting up a long strip of woven plate, and the long strip of plate is firstly cut into small-sized plate pieces by the cutting device, and then the plate pieces are respectively hot-pressed and bent into a plate strip by the bending device, and are conveyed to the material receiving device at the rear end one by the conveying device to arrange and receive the material, and the left and right of the structure body of the bending device and the conveying device are respectively set on the two inner walls which are opposite to each other left and right (the double-folding bending device is only set on a single inner wall), and the two opposite inner walls can be adjusted by the adjusting device to adjust the relative distance, the power device comprises a driving chain wheel which is linked by a motor and then is driven to a transmission chain wheel of the bending device by a chain, and a rotating shaft of the transmission chain wheel is fixed on the inner wall to rotate; in addition, in order to improve the defects that the driving chain wheel and the transmission chain wheel are easy to break and difficult to maintain due to chain transmission, the gear set can be used for transmission on the outer side of the inner wall (the side not provided with the chain wheel), but the position of the rotating shaft of the original chain wheel is not changed. The bending device is arranged on the inner wall in a spanning mode and located above the transmission chain wheel, the bending device comprises a bending die, a longitudinal push rod group, a cam group and other component bodies, wherein the cam group comprises three or four cams which are respectively arranged on the inner side and the outer side of the inner wall and rotate coaxially with the transmission chain wheel, so that the corresponding longitudinal push rod group is driven to act, and the longitudinal push rod group drives each bending component in the bending die, such as a swing arm of a hot pressing seat, to act, and therefore the multi-direction operation action process of hot pressing and bending is achieved. However, the structural design of the bending device in the conventional plate bending cutting machine has the following disadvantages in use:

(1) The cam set of the bending device in the conventional plate bending cutting machine is fixedly arranged on the rotating shaft of the transmission chain wheel, especially is respectively arranged on the inner side and the outer side of the inner wall, so that the assembly is troublesome, and the relative position is fixed and is not easy to adjust.

(2) The plate strip can be roughly divided into three different bending modes of folding, folding at two sides, hanging, and the like, different widths of the plate strip can be controlled by adjusting the relative distance through the adjusting device, and different bending modes are achieved by different bending devices, however, the use of different bending modes is only required to replace a bending die in the bending device, and a longitudinal push rod set and a cam set in the bending device are limited by the structural design of a machine and cannot be replaced along with the bending die, so that the same longitudinal push rod set and the cam set are used for driving three different bending die to act, the action process of each bending component in the bending die, such as a swing arm of a hot pressing seat, cannot be accurately mastered, the bending quality of the plate strip cannot be effectively controlled, the reject ratio is improved, and the requirements of the plate strip market on increasingly higher quality and higher mass production speed cannot be met.

(3) Although the cam group can be adjusted when the bending die is replaced so as to improve the accuracy when the same group of the longitudinal push rod group and the cam group drive different bending dies to act, the action process of the swing arm of the hot pressing seat is quite quick, so that the adjustment work is quite time-consuming and labor-consuming and is not easy to effectively achieve, and the trouble of bending replacement is caused.

(4) The bending and cutting machine for the similar foreign plates has been designed to replace all devices including the bending device, the conveying device, the material receiving device and the like on the table board of the machine for different bending modes, but the whole combination has large size and heavy weight, is difficult to store or replace, and has high cost and is not in accordance with the economic principle.
