4.1 The profile forming machine shall comply with the requirements of this standard and be manufactured in accordance with the drawings and technical documents approved through the prescribed procedures. 4.2 The fixed roller of the press is a chilled iron roller, and its mechanical properties and technical requirements shall comply with the provisions of GB9709. 4.3 The movable roller of the molding machine is a steel roller, and its mechanical properties shall meet the following requirements: tensile strength shall not be less than 560N/mm2, service strength shall not be less than 280N/mm, and surface hardness shall not be less than the requirements of HB180. 4.4 The roughness Ra value of the working surface of the roller shall not be greater than 1.6μm. The standard approved by the Ministry of Chemical Industry of the People's Republic of China on August 19, 1991 and implemented on January 1, 1992 is HG/T2147--91. 4.5 The bearing surfaces of the slide grooves of the roller bearings installed on the left and right turntables of the molding machine shall be on the same axis, and their flatness shall comply with the requirements of the 7th grade tolerance value in Appendix 1 of GB1184.
4.6 The bearing holes of the left and right frames of the type machine should be on the same axis, and their coaxiality should comply with the provisions of the 8th grade tolerance value in Appendix 4 of GB1184.
4.7 The total axial clearance between the two end faces of the saw shaft neck of the type machine and the end face of the j bearing should be within the range of 0.7~1.5mm. 4.8 The rotary plate of the press machine should rotate flexibly, and the locking device should work reliably. 4.9 The heating and cooling system must be subjected to a pressure resistance test, and the test pressure shall not be lower than 1.5 times the working pressure, and the pressure shall be maintained for 5 minutes without leakage.
The pipeline of the lubrication device should be cleaned, unobstructed, and without leakage. The motor power of the press machine when it is running idle shall not be greater than 15% of the rated power. When the press machine is running idle, the temperature rise of the roller bearing shall not exceed 20°C, and there shall be no sudden rise. 4.13
When the press machine is running under load, the temperature rise of the roller bearing shall not exceed 40°C. 4.14
The appearance quality of the press machine shall comply with the provisions of HG5-1541. The paint quality of the press machine shall comply with the provisions of ZBG95010. 4.15
5 Safety requirements
5.1 Emergency brake control devices shall be installed at the front and rear of the press machine. After braking, the roller shall not continue to rotate more than 1/4 of the circumference of the drum. 5.2 The press machine shall run smoothly. No abnormal vibration: The noise sound pressure level during operation shall not be greater than 80dB (A). 5.3 The transmission parts of the press machine exposed outside the machine shall have protective devices. 6 Test method
Idle running test
After the whole machine passes the general assembly inspection, an idle running test of no less than 2h (each movable roller runs for 0.5h respectively) shall be carried out. 6.1.1
6.1.2. The following items shall be checked in the idle running test: 8.
Measure the linear speed of the roller;
According to the provisions of Article 4.8, check the switching flexibility of the turntable and the reliability of the locking device; check the motor power value:
d., check the roller bearing temperature according to the provisions of Article 4.12: e.
Check the reliability of the installation device according to the provisions of Article 5.1: Measure the noise level with a sound level meter, which shall comply with the provisions of Article 5.2. 6.2 Load running test
The load running test can only be carried out after the idle running test is passed. 6.2.1
The load operation test time shall not be less than 2h, and the following items shall be checked: 6.2.2
The heating and cooling piping system shall not leak under working pressure: The overflow of roller bearing shall be measured with a point overflow meter, which shall comply with the provisions of Article 4.13: The noise sound pressure level shall be measured with a sound level meter, which shall comply with the provisions of Article 5.2. 7 Inspection rules
7.1 Factory inspection
