Technical Field

[0001] This utility model relates to the field of packaging bag sealing technology, and in particular to an intelligent lubrication control device for cold heading machines. Background Technology

[0002] Cold heading machines are the core equipment for cold forming of metal fasteners (such as bolts and nuts). Their key components, such as sliders, mold guide pillars, and main bearings, require continuous and stable lubrication under high-frequency impact and high-pressure load conditions to reduce friction loss and ensure equipment life.

[0003] The existing lubrication system of cold heading machine mainly controls the oil pump to supply oil through time relay. It cannot match the dynamic operating conditions such as no-load / full-load and different speeds of the equipment. This can easily lead to "under-lubrication" of key components, which will aggravate wear, or "over-lubrication", which will cause oil waste and pollution. Utility Model Content

An intelligent control device is provided at the end of the oil delivery pipe away from the oil outlet. The intelligent control device includes a main oil circuit control valve fixedly installed at the end of the oil delivery pipe away from the oil outlet. A progressive distributor is fixedly installed on the surface of the main oil circuit control valve, and the oil outlet of the main oil circuit control valve is connected to the oil inlet of the progressive distributor through a branch pipe.

[0006] Preferably, a monitoring pipe extends horizontally from the right side of the main oil circuit control valve, and a main oil circuit pressure sensor is fixedly installed at the end of the monitoring pipe. The proportional valve is fixed to the cold heading machine frame by a pipe clamp.

[0007] Preferably, the bottom of the progressive distributor is provided with a branch pipe, and the oil inlet of the proportional valve is connected to the oil outlet of the progressive distributor through the branch pipe.

[0008] Preferably, the signal interface of the electric oil pump motor junction box is connected to a pulse cable, and the other end of the pulse cable is connected to the terminal block of the PLC controller.

[0009] Preferably, the signal interface of the proportional valve is connected to an analog cable, and the other end of the analog cable is connected to the AI ​​module of the PLC controller.

[0010] Preferably, the human-machine interface screen is fixed to the right side of the cold heading machine operation panel by a cantilever bracket, and the human-machine interface screen is a capacitive touch screen with an anti-glare film on the screen surface.

[0011] Preferably, the network port of the human-machine interface screen is connected to a communication cable, and the other end of the communication cable is connected to the Ethernet interface of the PLC controller. The communication cable is a Category 5e shielded network cable.

The human-machine interface screen 9 is fixed to the right side of the cold heading machine operation panel by a cantilever bracket.

[0019] Reference Figure 1-2 As shown in this embodiment: A smart control device 2 is installed at the end of the oil pipeline 7 furthest from the oil outlet 5. The smart control device 2 includes a main oil circuit control valve 201 fixedly installed at the end of the oil pipeline 7 furthest from the oil outlet 5. A progressive distributor 202 is fixedly installed on the surface of the main oil circuit control valve 201. The oil outlet of the main oil circuit control valve 201 is connected to the oil inlet of the progressive distributor 202 via a branch pipe 203. A monitoring pipe 204 extends horizontally from the right side of the main oil circuit control valve 201. A main oil circuit pressure sensor 205 is fixedly installed at the end of the monitoring pipe 204. A proportional valve 207 is fixed to the cold heading machine frame via a pipe clamp. A branch pipe 206 is provided at the bottom of the progressive distributor 202. The oil inlet of the proportional valve 207 is connected to the oil outlet of the progressive distributor 202 via the branch pipe 206. A pulse cable 208 is inserted into the signal interface of the motor junction box of the oil pump 1. The other end of the pulse cable 208 is inserted into the terminal block of the PLC controller 8. An analog cable 209 is inserted into the signal interface of the proportional valve 207. The other end of the analog cable 209 is inserted into the AI ​​module of the PLC controller 8. A communication cable 210 is inserted into the network port of the human-machine interface 9. The other end of the communication cable 210 is connected to the Ethernet interface of the PLC controller 8. The communication cable 210 is a Cat5e shielded network cable. A lubrication pipe 211 is fixedly connected to the oil outlet of the proportional valve 207.

[0020] Working principle: First, the electric oil pump 1 starts and draws oil from the lubricating oil tank through the oil-resistant hose 6. The oil is output from the oil outlet 5 through the oil inlet pipe 4 and is transported to the main oil circuit control valve 201 in the intelligent control device 2 through the oil delivery pipe 7. The main oil circuit control valve 201 initially adjusts the oil pressure. Then, the adjusted oil enters the progressive distributor 202 through the branch pipe 203. The progressive distributor 202 coarsely distributes the oil to each branch pipe 206 according to the preset ratio. Then, the branch pipe 206 delivers the oil to the proportional valve 207. The proportional valve 207 dynamically adjusts the opening according to the analog signal output by the PLC controller 8 through the analog cable 209 to achieve precise adjustment of the oil flow. The finely adjusted oil is delivered to each lubrication point of the cold heading machine through the lubrication pipe 211. Furthermore, the main oil circuit pressure sensor 205 monitors the main oil circuit pressure in real time through the monitoring pipeline 204, while the branch pressure sensor 212 monitors the pressure at the outlet of the proportional valve 207 through a T-type tee connector. The monitoring data is transmitted to the PLC controller 8 via cable. Finally, the PLC controller 8 generates control commands based on the received pressure data and preset algorithms, adjusting the speed of the electric oil pump 1 through the pulse cable 208 to stabilize the main oil circuit pressure, and simultaneously correcting the opening of the proportional valve 207 in real time through the analog cable 209. The human-machine interface screen 9 is connected to the PLC controller 8 through the communication cable 210, displaying data such as pressure and flow rate in real time, and supporting parameter settings, forming a closed-loop control of "perception-decision-execution-feedback" to ensure that each lubrication point of the cold heading machine is supplied with oil accurately as needed.
