Most of the materials purchased by hardware processing companies are coiled and packaged materials. These materials must be unrolled before being fed into the press, and the materials are unrolled and then leveled to eliminate internal stress. In the past, the pretreatment of the coil material was mainly carried out manually, and the work efficiency was low. When the material was flattened, it was easy to hurt the human body, and the safety was not good. Secondly, the quality could not be guaranteed, so the current hardware processing factory Automated stamping lines are used to unwind and level the materials, but these peripheral automated production lines usually require two or more independent equipment (such as the commonly used heavy material rack + leveling machine + feeder, two-in-one rack) The combination of flattening machine and feeder is used in combination, and the waiting area with long interval is required in the middle, which occupies a considerable space inside the factory, 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 is composed of a main frame, a rack portion on the rack, and a flat feeding portion, wherein the rack portion includes a loading rack and a power shaft disposed on the loading frame, and the power shaft is provided with The supporting material plate, the front and the side of the power shaft are respectively provided with a pressing arm and a material limiting rod, the cylinder is connected with a cylinder, and a supporting frame is arranged below the power shaft; the flat feeding part comprises a machine base and is arranged on the machine The power assembly in the seat has a roller seat on the base, and an adjustable material width limit support frame is arranged in front of the roller seat, and the three-in-one feeder feeds the coil material on the support tile plate by type A iron and material. The roll limit rods respectively limit the coil material from the inner and outer directions, so that they are stable when rotated, and are controlled by the photoelectric material arc control system to be fed into the leveling feeding portion, which is driven by the power assembly in the flat feeding part base. The force shaft is sequentially fed and leveled according to the frequency matched with the punching machine, and then the pretreated material is sent out. The three-in-one feeder combines unwinding, leveling and feeding, but it is by no means a simple combination of these three models. It has four major advantages in structure:
1. The rack part:
The hydraulic expansion system automatically tightens and relaxes the material, with high reliability and low labor intensity. The pressure arm adopts frequency conversion speed regulation and one-way clutch transmission, so that the material will not be loose. The material is discharged by photoelectric sensing system. The feeding guide rail adopts a pneumatic lifting material, and a pneumatic feeding plate pressing device is arranged at the feeding port, and the material head is pressed down to be automatically fed into the leveling machine.
2. Leveling part:
The rolling bearing steel is hard-hardened and hard chrome-plated. The surface hard plating can reach above HRC 62 degrees. There is an adjustable reinforcing device in the middle of the roller to increase the rigidity of the roller. The upper roller adopts a 2-point fine-tuning structure and is adjusted by a worm gear. The pressure is small, the speed is light and the precision is high, and the loose part adopts the pneumatic arm linkage mechanism, which has high flexibility and self-locking. The flattening and relaxation adopts the eccentric structure, and the electrical signal given by the punching machine relaxes and presses the powerful guiding material accurately.
3. Feeding part:
Worm gear reducer, metal bellows coupling, no drive clearance, no corner error, the upper and lower feed rollers adopt a gapless rotation structure. At the same time, the encoder is used to control the feeding precision, and the automatic compensation is provided when the delivery is small, the feeding is accurate, and the error is extremely low.
4. the nose part:
The discharge height adopts the worm wheel lifting system, which makes the feeding height adjustable within a certain range. The height can be adjusted according to the punching die line, the range can reach 150mm, and the adjustment is convenient and labor-saving.
At the same time, the three-in-one feeder is equipped with a pneumatic press arm to protect the personal safety when the elastic release of the coil is released. The traditional three independent peripheral devices are combined into one device with three functions. The volume has been greatly reduced, which greatly saves the space occupied, the structure is optimized, and the humanized design makes the three-in-one feeder easy to operate and use, which makes the product defect rate greatly reduced. Greatly improve production efficiency and quality of processed products.
