Description

Technical Field

[0001] This utility model belongs to the field of prestressed concrete pipe pile production and manufacturing, and in particular relates to an automatic lubrication machine for mold closing screws, which is a device specifically designed for the automatic lubrication of spring screws in pipe pile molds. Background Technology

[0002] Spring screws for pipe pile molds are widely used in the molding and manufacturing of concrete products such as pipe piles, utility poles, and drainage pipes. Installed at the upper and lower ends of the steel mold, they use elasticity to achieve the movable fit between the upper and lower molds under vibration, avoiding damage caused by existing bolt positioning, aiding demolding, reducing demolding strength, and increasing demolding speed.

[0003] Pipe pile mold spring screws operate in high temperature and high humidity environments for a long time, making them prone to rust and wear. They require regular lubrication and maintenance. Currently, manual lubrication is commonly used, but the large number of screws makes manual operation inefficient, resulting in poor lubrication and high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic lubrication machine for mold closing screws that can improve work efficiency, provide good lubrication effect, reduce costs, and simplify maintenance.

[0005] The purpose of this utility model is achieved through the following technical measures: an automatic lubricating machine for mold clamping screws, characterized in that it includes an electrical control unit, an oil tank, an oil supply pipe connected to the oil tank, a rotating arm mounting frame, a rotating arm, a rotating oil passage block, and several lubricating rods. The first end of the rotating arm is hinged to the rotating arm mounting frame, and the second end is rotatably mounted with the rotating oil passage block. Each lubricating rod has a first oil supply channel. Each lubricating rod is distributed along the circumference of the rotating oil passage block, and one end of each lubricating rod is connected to the rotating oil passage block, while the other end is equipped with an oil nozzle communicating with the first oil supply channel. A lubricating oil distribution structure is provided between the rotating oil passage block and the rotating arm for sequentially distributing lubricating oil from the oil supply pipe to each lubricating rod.

[0006] This invention enables automated lubrication, improving operational efficiency.

Detailed Implementation

[0031] like Figures 1-6 As shown, this utility model discloses an automatic lubricating machine for mold clamping screws, comprising an electrical control unit, an oil tank 1, an oil supply pipe 2 connected to the oil tank 1, a rotating arm mounting bracket 4, a rotating arm 5, a rotating oil passage block 6, and six lubrication rods 7.

[0032] In this embodiment, the lubricating oil distribution structure includes a vertical mounting shaft 9 located at the second end of the rotating arm 5, a mounting groove 61 located inside the rotating oil passage block 6, and several second oil delivery channels 62. The mounting shaft 9 has an L-shaped third oil delivery channel 91.

A second oil channel 62 extends radially along the rotating oil passage block 6 and is distributed circumferentially. The inlet of the second oil channel 62 corresponds to the outlet of the third oil channel 91, and the outlet of the second oil channel 62 communicates with the first oil channel 71 of the filler rod 7. This allows the third oil channel 91 to sequentially connect with each of the second oil channels 62 when the rotating oil passage block 6 rotates, delivering lubricating oil to the first oil channel 71 of the filler rod 7. A threaded hole 18 is provided at the bottom of the mounting groove of the rotating oil passage block 6. A screw (not shown in the figure) is installed in the threaded hole 18 for sealing, and during disassembly, the screw can be screwed upwards to push out the mounting shaft 9.

[0033] The rotating arm mounting bracket 4 is fixed on the conveying equipment 15 used to transport the cover mold 17. The lubrication rod 7 is pushed by the mold closing screw 16 on the cover mold 17, which drives the rotating oil passage block 6 to rotate, so that the lubrication rod 7 contacts the mold closing screw 16 in sequence and sprays lubricating oil. The first end of the rotating arm 5 of this utility model can be adjusted in height on the rotating arm mounting bracket 4, so as to adjust the lubrication rod 7 to a suitable height.

[0034] The electronic control unit includes a controller, a drive mechanism for driving the rotating arm 5 to rotate, an oil circuit solenoid valve 3 installed on the oil supply pipe 2, a first sensor for sensing the cover mold 17 to start the transmission after a delay, a second sensor for sensing the refueling lever 7 to reach the limit position, and an oil pump 14 connecting the oil tank 1 and the oil supply pipe 2. The oil pump 14 is a diaphragm pump. The drive mechanism includes a cylinder 10, two sets of pneumatic pipelines, and a pneumatic solenoid valve 13. The two sets of pneumatic pipelines include a first set of pneumatic pipelines 11 and a second set of pneumatic pipelines 12. The cylinder body of the cylinder 10 is fixedly connected to the rotating arm mounting bracket 4, and the push rod of the cylinder 10 is hinged to the rotating arm 5. The pneumatic solenoid valve 13 is connected to compressed air B. The pneumatic solenoid valve 13 is connected to the cylinder 10 through the first set of pneumatic pipelines 11 and to the oil pump 14 through the second set of pneumatic pipelines 12. The pneumatic solenoid valve 13, the oil circuit solenoid valve 3, the first sensor, and the second sensor are respectively connected to the controller.

[0035] The lubricating oil used in this invention can be grease, waste engine oil, or clean engine oil.

[0036] This utility model is fixed to the fixed bracket of the conveying equipment by the rotating arm mounting bracket 4. The purpose of this utility model is to lubricate the mold closing screws 16 on the cover mold 17. The cover mold 17 with mold closing screws 16 is the prior art. The mold closing screws 16 are arranged on the cover mold 17 along its length direction, and there is a certain distance between adjacent mold closing screws.

[0037] The parameters of this utility model are as follows: power supply: AC 220V, 50Hz; air pressure: 0.1-0.6MPa; power: ≤10W; oiling volume: 0.1-5ml / time adjustable; external dimensions: 800mm×660mm×350mm (length×width×height); weight: approximately 20kg.

[0038] The operation and working process of this utility model is as follows:

[0039] 1. This utility model is installed on both sides of the conveying equipment and in a suitable position using a swivel arm mounting frame to ensure convenient lifting of the cover mold.

[0040] 2. Turn on the power switch and add appropriate lubricating oil to the oil tank.

[0041] 3. Place the mold that needs lubrication on the conveyor belt of the conveyor equipment. This utility model will then operate automatically and lubricate each mold closing screw that passes through. After lubrication is completed, the mold is lifted away, and one lubrication process is completed.

[0042] like Figure 4 As shown, the specific oiling process is as follows: When the mold to be oiled is hoisted onto the chain conveyor belt, the first sensor detects the mold and sends information to the controller. The controller then controls a delayed start of the conveyor belt. Simultaneously, the controller energizes the pneumatic solenoid valve, which splits into two working air paths. The first working air path leads to the cylinder, pushing the rotating arm to rotate so that the oiling rod approaches the edge of the mold and automatically contacts the first mold closing screw. The second working air path leads to the diaphragm pump, which begins pumping oil. When the oiling rod contacts the first mold closing screw, the oil spray nozzle on its side sprays lubricating oil onto the mold closing screw, thus starting the conveyor belt. As the cover mold moves with the conveyor belt, the six lubrication rods begin to rotate under the drive of the mold-closing screws. The number of lubrication rods in this invention is designed according to the interval between adjacent mold-closing screws, allowing for precise sequential contact with the screws. When a lubrication rod rotates to contact a mold-closing screw, the oil supply channel inside the rotating oil circuit block connected to that rod and the oil supply channel of the mounting shaft are connected. Lubricating oil is sprayed onto the mold-closing screw under the action of the diaphragm pump, providing a quantitative amount of lubricating oil to the screw. The oil circuits of the other lubrication rods that are not in contact with the mold-closing screws are disconnected, and no lubricating oil can be sprayed out. After this invention has lubricated the last mold-closing screw on the cover mold, the second sensor senses the lubrication rod that lubricated the last mold-closing screw, triggering the limit position, de-energizing the solenoid valve, and ending one lubrication process.

[0043] 4. Regularly check the oil level to ensure the equipment is operating normally.

[0044] The embodiments of this utility model are not limited to this. Based on the above content of this utility model, and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, the lubricating oil distribution structure of this utility model may have other embodiments. Therefore, this utility model can also be modified, replaced or changed in various other forms, all of which fall within the scope of protection of this utility model.
