Description

Technical Field

[0001] The invention relates to the field of tank truck production, in particular to an energy-saving plate rolling machine for a tank truck. Background Art

[0002] The production of tank bodies of tank trucks includes cutting the arc-shaped plates into the shape of heads through a bulging machine, and then using a hemming machine to erect the edges of the heads to form a complete head. The square plates are rolled into the shape of cylinders through a plate rolling machine. After the cylinder is formed, longitudinal seam welding is performed to ensure the continuity and sealing of its structure. Internal structural components such as corrugated plates and bulkhead plates are made through machining processes such as stamping, bending, punching, shearing, flanging, etc., and then spliced ​​through devices.

[0003] The existing patent publication number is (CN109013702A) a stainless steel plate press with a carbon dioxide protection device, including a stainless steel plate press body, the stainless steel plate press body has a frame, a pressing roller is provided on the frame, a first oil tank is arranged around the pressing roller, during the pressing of the steel plate, lubricating oil is placed in the first oil tank, and the pressing roller is immersed in the first oil tank: it also includes a carbon dioxide storage tank, the carbon dioxide storage tank has an outlet, and a pipeline is installed at the outlet, the other end of the pipeline is connected to a nozzle, the nozzle is arranged toward the oil tank, a first solenoid valve is installed in the middle of the pipeline, and the first solenoid valve has a control switch. Such a stainless steel plate press has the advantages of being able to extinguish burning fires in time and reduce losses.

[0004] The lubrication in this technical solution adopts oil tank lubrication, which has a good lubrication effect but wastes lubricating oil and is not energy-efficient.

[0005] The existing patent publication number (CN114406054B) is a circulating lubrication plate rolling machine, which discloses that the lubricating liquid is filled inside the upper rolling wheel, and the lubricating liquid flows to the self-lubricating rotating shaft during its rotation to lubricate it, and at the same time, the excess lubricating liquid is transferred to the primary liquid collecting cavity in the collecting rings on both sides through the liquid storage channel opened inside the self-lubricating rotating shaft, and then the lubricating liquid is transferred to the secondary liquid collecting cavity inside the rotating ring by using the conduit in the rotating ring, and the lubricating liquid is introduced into the upper rolling wheel through the secondary liquid collecting cavity;

[0006] This technical solution forms a complete lubricant circulation, which not only improves the lubrication effect and saves lubricant, but also improves the heat dissipation effect, further improving the quality of the produced rolled plates. However, the groove inside the upper rolling roller leads to a decrease in strength. In order to ensure safety, the tank truck body is made of high-strength materials, and the use of a grooved upper rolling roller is prone to deformation of the upper rolling roller;

[0007] Since the cross-sectional shape of the car tank is elliptical, a four-roller press is often used for pressing. If an oil dripping device is fixedly installed above the upper roller, the plate is likely to interfere with the oil dripping device during the pressing process. In summary, a method is needed that can save the use of lubricating oil and reduce the interference of the oil dripping device on the plate processing. Summary of the invention

[0041] The oil drip hose 62 includes an internal sandwich 621 for maintaining strength, and an outer soft cover 622 for reducing collision. The surface of the oil drip hose 62 is provided with oil drip holes 623. Such an arrangement can ensure that the oil drip hose 62 has a certain strength and will not scratch the upper pressure roller 2 when it contacts the upper pressure roller 2 during the retraction process.

[0042] A shell 67 is provided on the outer side of the winding wheel 61, and the shell 67 is fixedly connected to the support frame 1. The winding wheel 61 includes a center sleeve 611, and the center sleeve 611 is rotatably connected to the middle part of the shell 67. The outer surface of the center sleeve 611 located inside the shell 67 is fixedly installed with symmetrically arranged baffle rings 612, and the oil dripping hose 62 is wrapped around the two baffle ring 612 brackets. The outer surface of the center sleeve 611 located in the middle of the two baffle rings 612 is provided with a through hole 613, and the oil dripping hose 62 is sleeved on the inside of the center sleeve 611 through the through hole 613 and extends to the outside of the shell 67. Through such an arrangement, the oil dripping hose 62 can be wrapped around the outer surface of the center sleeve 611 and pass through the center sleeve 611 for oil supply. A gear 614 is fixedly installed on the side of the center sleeve 611 away from the outlet of the oil dripping hose 62, and a power source 615 for rotating the gear 614 is fixedly installed on the outer side of the shell 67.

[0043] Two extrusion wheels 616 are symmetrically rotatably connected to the upper part of the shell 67 , and the oil dripping hose 62 is sleeved in the gap between the two extrusion wheels 616 . The two extrusion wheels 616 squeeze each other to straighten the oil dripping hose 62 .

A fixing ring 619 is fixedly installed on the outer surface of the outer shell 67. The limiting ring 618 is rotatably clamped on the outer surface of the fixing ring 619. Through such an arrangement, it can be ensured that the oil drip hose 62 can rotate with the center sleeve 611 and realize continuous oil supply while achieving continuous oil supply.

[0045] The clamping mechanism 66 fixes the annular groove pressure wheel 661, and elastic telescopic pull rods 662 are fixedly installed on both sides of the free end of the telescopic sleeve 65.

The oil dripping hose 62 is clamped between the fixed annular groove pressure wheel 661 and the raised pressure wheel 663. The entire clamping mechanism 66 can be retracted to below the upper cross-section of the upper pressure roller 2 through the telescopic sleeve 65, thereby avoiding interference. The raised pressure wheel 663 can move up and down relative to the fixed annular groove pressure wheel 661, and can fix the oil dripping hose 62 located in the annular groove.

[0046] A sliding sleeve 8 is arranged above the support frame 1, and a lifting frame 9 is fixedly installed on the fixed end of the sliding sleeve 8. The lifting frame 9 is located on the side of the support frame 1 away from the choke 5. An extrusion sleeve 10 is fixedly installed on the free end of the sliding sleeve 8.

Through such a setting, the extrusion sleeve 10 can be used to push the limiting airbag 63 to move, thereby driving the oil dripping hose 62 to move. When passing through the fixed ring groove pressure wheel 661 and the raised pressure wheel 663, the limiting airbag 63 can be squeezed to deform and cooperate with the fixed ring groove pressure wheel 661 and the raised pressure wheel 663 to move up and down, so that the limiting airbag 63 can pass through, and will not drive the limiting airbag 63 to move during the retraction process.

Through such an arrangement, the injection angle can be changed, so as to adapt to different contact positions of the workpiece when the side pressure roller 4 or the lower pressure roller 3 is working.

[0048] There are multiple gear rings 73, which are evenly distributed. The thickness of the gear ring 73 is smaller than the injection radius of the spray hole 72. Since the workpiece is relatively long, multiple gear rings 73 can be provided to facilitate the rotation of the device.

[0049] When in use, by arranging the oil dripping mechanism 6 at the top and the oil spraying mechanism 7 at the bottom, the extruded inner wall and the stretched outer wall of the rolled plate can be lubricated at the same time, thereby improving the heat dissipation and lubrication effects and reducing the use of lubricating oil;

[0050] The extrusion sleeve 10 is pushed to move by extending the sliding sleeve 8, and the extrusion sleeve 10 pushes the limiting airbag 63 to move, which can drive the oil dripping hose 62 wrapped around the winding wheel 61 to move together, so that the limiting airbag 63 and the oil dripping hose 62 can be moved together to the fixed groove extrusion wheel 616 and the raised extrusion wheel 616 for clamping, and the upper pressing roller 2 can be lubricated by the oil dripping hose 62 for continuous oil dripping above the upper pressing roller 2. When the plate is bent and is about to contact the oil dripping hose 62 above the upper pressing roller 2, the power source 615 drives the winding wheel 61 to reel, so that the oil dripping hose 62 can be pulled to reel, so that the limiting airbag 63 can be pulled to be extruded and deformed, and the fixed annular groove pressing wheel 661 and the raised extrusion wheel 616 can move relative to each other, so that the limiting airbag 63 can pass through, and the oil dripping hose 62 can be reeled onto the surface of the winding wheel 61, so that the oil dripping mechanism 6 can be prevented from interfering with the workpiece.

[0051] At the same time, the rotation of the rotating shaft 75 can drive the driving gear 74 to rotate, and then drive the ring gear 73 to rotate, so as to change the position of the spray hole 72 of the oil injection pipe 71, so as to follow the working status of the lower pressure roller 3 and the side pressure roller 4 and change the injection position in time.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.
