III. Working principle and structure overview

This machine is mainly composed of motor, reducer, chain drive device, body, die frame, electric control cabinet, car and car traction chain drive device.In order to facilitate transportation and installation, the machine body is made into a combined structure, disassembled for several sections during loading and assembled into a whole during installation, which is convenient and feasible.

To start the machine, the main motor should be started first to make the drawing chain run, and then the clamping trolley should be started to return

The motor and the clamping trolley are driven by the traction chain to move rapidly towards the die frame. When the rod on the trolley is in contact with the stroke on the machine, the return motor will stop immediately.Under the action of the plunger bar, the hook of the car automatically falls on the small shaft of the drawn chain, At the same time, the clamping jaw clamps the bar head through the die hole with the drawing force and moves forward with the drawing chain, bar is drawn from the die hole, bar end come out from the die hole, because the clamp pliers lose drawing force and jaw automatic open, finished product bar will fall off into the finished product basket along the arm.When the hook on the clamping trolley cannot automatically fall down for some reason, the operator can press down the hook instead of mechanical action.

IV: Lubrication of equipment

This machine is using oil cup, oil pool and by directly by pouring thin oil, No. 1 calender grease is used for all oil cups in winter, summer with 2 calender grease, Dry oil lubrication parts shall be rotated for 3 to 4 times per shift, The reducer is lubricated with oil sump, no. 50 machine oil, once every six months to replace oil,and often keep the oil tank oil level, drawing chain, car traction chain and exposed parts of the movement of thin oil are poured directly lubrication, no less than a second in each shift.

V. preparation before test run

1. Check the connection status of all fasteners:

2. Check whether the lubrication of each lubrication point is good and effective:

3. Check whether the action of switch of electrical components is correct and whether the effective circuit connection is reliable:

4. Check and test whether the clamping action and hook action of the clamping trolley are accurate and reliable:

5.Clear the moving parts of the machine and surrounding objects, make sure everything is normal before starting.

VI. Maintenance and safety

1. Check the fastening condition and wear degree of machine parts regularly, and replace worn parts at any time.

2. Check the temperature rise of the bearing regularly. When the temperature is not higher than 60 C, stop the machine immediately to check and find out the reason.

3. Pay attention to the supply of lubricating oil, check the oil level of the reducer frequently, and fill it immediately if it is insufficient.

4. Pay attention to the wear of bearing bearing and adjust or replace it if necessary.

5. When starting the main motor, there shall be no load on the drawing chain.

6. If abnormal noises are found in the reducer, stop the machine immediately for inspection.

7. Keep the mold, guide surface and all moving parts clean regularly.

8. The machine should be operated by a special person, and non-operators are forbidden to start the machine.

9. During the quick return and drawing of the clamping trolley, it is strictly prohibited for any non-staff to approach the guide rail.

Electric control cabinet and airframe should be well grounded.
