Analysis Of The Operation Method And Process Of Hydraulic Press

It is an essential equipment for shoemaking. It is mainly used for shoes.

Adhesive bonding.

It is suitable for the bottom of the dragon boat, the wall bottom type sneakers, the casual shoes and other shoes or the shoes of Baotou. The pressing, pressing and pressing of the shoes can be completed or individually completed at one time. The pressure is large and the bonding is firm.

Upgraded automatic bottom pressing machine.

Let's take a look at the operation and process of hydraulic press.

Operation method of hydraulic press machine:

1. When using the bottom press, pay attention to the accuracy of the marking board, so that the air pressure is about 0.

6MPa.

2. Rough grinding must remove the paint on the leather surface according to the radian after marking.

3. The surface of the big bottom must be treated with potion.

4, heating should be at 100 degrees C or 5 degrees Celsius.

5, before the bottom, the shoe and sole must pay attention to the accuracy and uniformity of the glue and not to contaminate the upper and sole.

6, when the shoe is attached to the sole, the employee must pay attention to the bottom of the shoe.

7. When pressing the bottom, the operators should pay attention to the correctness of the use of the press, while at the same time pay attention to the control of press time (5-8S) and pressure (20-40KN).

8, after the completion of the pressure: sulfur shoes: must collect shoes in sulfur tank for sulfur solidification; cold sticky shoes: shoes must be placed in the freezer, frozen stereotypes.

9. After the bottom is pressed, the shoe is not completely cooled until it is finalized, so it is best not to remove the shoe last, so that the shoes will be deformed.

1. press the bottom press according to the model of the last type, the upper and the sole, and press the bottom mould. The pressure is 20~25 kg, and the time is 5~8 seconds.

2. the die must conform to the shoe type, and the pressure bar and the rear heel die should be adjusted and replaced according to the different shoe types.

3. a new type of body weight must be tested before birth, and the examination should be compared with the left and right feet.

4. depending on the situation, the material is adjusted to press the bottom press, and the general pressing time is 6 seconds.

5. the bottom die is in accordance with the shoe type, and the pressing bar and the heel top mould should be adjusted and replaced according to different shoe types.

6. press machine at any time attention to press after completion, compare the left and right foot shoes tilt, focus point, front and rear hoof, etc., and then put into the conveyor belt.

7. check the power switch, the general pressure is about 20 kg, the time is 5~6 seconds, fixed standard press die, press the green key to twist, use foot pedal switch, turn off the machine to press the red key, make daily and regular maintenance.
