Most of the materials purchased by hardware processing companies are coiled and coiled coils. These materials must be unrolled before being fed into the punching machine. The material is unrolled and then leveled to eliminate internal stresses. In the past, the pretreatment of coils was mainly carried out manually by hand. As a result, the work efficiency was low, and the leveling material was easy to injure the person when it was cut, resulting in poor safety. Secondly, the quality could not be guaranteed. Therefore, the current hardware factory The automated press lines are used for the unwinding and leveling of materials, but these peripheral automated lines usually require two or more independent devices (such as the commonly used heavy material frame + leveler + feeder, 2-in-1 material rack The combination of the leveling machine and the feeder is used in combination. In the middle, a longer waiting area is required, which takes up a large space within the plant, and the degree of automation is not high and the operation is complicated.

The three-in-one feeder is a new type of automatic feeding equipment specially developed and produced to solve the problem of equipment occupation and improve the automation degree of stamping production. The three-in-one feeder consists of a main body frame, a rack part on a rack and a leveling feeding part, wherein the rack part includes a loading rack and a power shaft arranged on the loading rack, and the power shaft is provided with Feeding tile plate, the front and rear sides of the power shaft are respectively provided with a pressing arm and a material roll limit rod, a pressurizing arm is connected with an air cylinder, and a feeding rack is arranged below the power shaft; the leveling and feeding part includes a base and a machine In the power assembly of the seat, a roller seat is arranged on the seat, an adjustable material width limit supporting bracket is arranged in front of the roller bracket, and a three-in-one feeder is used to place the coil material on the supporting tile plate by the A-type iron and material. The roll limit rods respectively limit the reel material from both inside and outside to keep it stable during rotation. It is controlled by the photoelectric material arc control system and fed into the leveling and feeding part, and is driven by the power assembly in the leveling and feeding part of the machine base. The force axis is fed in and leveled in accordance with the frequency of the punch press, and then the pretreated material is sent out. The three-in-one feeder combines decoiling, leveling, and feeding, but it is by no means a simple combination of these three models. It has four major advantages in structure:

1, part of the rack:

With the hydraulic expansion system, the material is automatically tensioned and relaxed. The reliability is high and the labor intensity is low. The press arm adopts variable frequency speed control and one-way clutch transmission, so that the material will not be loose. Discharge using photoelectric sensor system, automatic discharge. The material guide rail is made of pneumatic lifting material, and a pneumatic feeding pressure plate device is arranged at the material inlet to push the material head into the leveling machine automatically.

2, leveling part:

GCr15 rolling bearing steel high-frequency hardening hard chrome plated, surface hard plated up to HRC62 degrees or more, in the middle of the drum with adjustable reinforcement device, increasing the rigidity of the drum, the upper roller adopts 2 points fine-tuned structure, with worm gear Adjustment of the amount of press, high labor-saving and high precision, the use of pneumatic crutches to relax part of the linkage mechanism, high flexibility and precision, self-locking. Leveling and relaxing uses an eccentric structure, through the electrical signal given by the punch, to relax quickly and effectively press down the correct guide material.

3, feeding part:

Adopt Japan Yaskawa servo motor, French high-precision, worm gear reducer, German metal bellows coupling, no transmission gap, no corner error, the upper and lower feed roller adopts no gap rotation structure. At the same time, the encoder is used to control the feeding accuracy, and when sending more and sending less automatically, the feeding is accurate and the error is extremely low.

4, head part:

The height of the discharge adopts the worm gear lifting system, so that the feeding height can be adjusted within a certain range. The height can be adjusted according to the press mold line, and the range can reach 150mm. The adjustment is convenient and labor-saving and reliable.

At the same time, three-in-one feeders are equipped with a pneumatic pressure arm to protect the personal safety when the elasticity of the coil is released. As the traditional three independent peripheral devices are combined into a device with three functions , The volume has been greatly reduced, greatly saving the space, the structure of the optimization, user-friendly design, so that three-in-one feeder operation, use is very convenient, making the product rate of defective products greatly reduced, Big increase the production efficiency and quality of processed products.
