Description

TECHNICAL FIELD

[0001] The utility model relates to the steel plant steel rolling line cooling bed equipment technical field, namely the cooling bed cam lubricating device. BACKGROUND

[0002] In the prior art, the main equipment of the straight bar type steel rolling production line of the steel plant comprises a heating furnace, a rolling mill, a cooling bed and a rear collecting device. The cooling bed is an important rolling stock storage device, and its working principle is as follows: the rolling stock rolled by the rolling mill enters the cooling bed apron and is thrown to the cooling bed straightening plate, the cooling bed step beam motor drives a transmission shaft through a worm and gear reducer, the cam device on the transmission shaft makes the upper supporting roller move forward and upward, thereby driving the rack of the step beam to act, and the moving rack cooperates with the static rack to output the rolling stock from the cooling bed. The lubricating mode of the cam transmission device of the cooling bed step beam is a cam oil immersion type lubricating mode, that is, when the cam is at a low position, the cam is immersed in the oil box, thereby achieving the purpose of lubricating the surface of the cam and the supporting roller. The defect of this mode is that during the stepping process of the rolling stock above the cooling bed, the iron sheet falls into the oil box and pollutes the lubricating oil, which leads to poor lubricating effect and aggravates the wear of the cam. Meanwhile, due to the complex structure of the cam device and the small space, the installation position of the oil pan needs to wrap 2 / 3 of the cam, and sometimes the edge of the oil pan may contact the cam, so that the oil on the cam directly flows to the ground along the outer wall of the oil groove. In addition, during the operation of the lubricated cam, the oil may splash and pollute the surrounding environment, and it is difficult to clean up. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at the above-mentioned shortage and provides a kind of cooling bed cam lubricating device, can avoid the problem of oil product pollution and lubricating oil product flow to ground after cleaning difficulty due to lubricating oil box pollution.

[0004] The technical solution of the utility model is as follows: a cooling bed cam lubricating device comprises a cam installed on a cam shaft, and an oil box is installed on the rack below the cam. A cam disc is installed near the middle of the cam shaft. A rotatable shaft rod supported by a bracket is arranged in parallel on one side of the front of the cam shaft. A sliding wiping plate is fixedly connected to the left end of the rotatable shaft rod in a perpendicular manner. The outer end of the sliding wiping plate can be connected to the outer circle of the cam disc. A lever is fixedly connected to the right end of the shaft rod in a cross and perpendicular manner. A rubber wheel capable of being inserted into the oil box is arranged at the front end of the lever. A counterweight is arranged at the rear end of the lever.

[0005] The two ends of the shaft rod are supported and connected by bearing seats.

[0006] The counterweight is composed of multiple parts and is fixedly connected by bolts.

[0007] A shielding plate is arranged above the cam.

[0008] The utility model discloses a cold bed cam lubricating device, including the cam 11 of installation on the cam axle 10, the oil box 4 of installation on the frame below the cam 11, it is characterized in that in the middle near of cam axle 10 installs the cam disc 1;One support supportable rotation axle rod 9 is arranged in parallel on the front side of cam axle 10, and the left end of rotation axle rod 9 has the perpendicular fixed connection of one sliding wiping plate strip 2, and the outer end of sliding wiping plate strip 2 can be connected with the outer circle of cam disc 1, and the right end of axle rod 9 has the perpendicular fixed connection of lever 7, and the front end of lever 7 has the rubber wheel 5 of being able to insert the oil box 4, and the rear end of lever 7 is equipped with the counterweight 8.

[0009] The embodiments of the utility model will be described further in detail below with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0013] Referring to Figure 1 , 2 , 3, the names of parts are as follows: cam disc 1, sliding wiping plate 2, support support rod 3, oil box 4, rubber wheel 5, bearing seat 6, lever 7, counterweight 8, shaft rod 9, cam axle 10, cam 11.

[0014] Referring to Figure 1 , 2 , the cold bed cam lubricating device includes the cam 11 of installation on the cam axle 10, the oil box 4 of installation on the frame below the cam 11, it is characterized in that in the middle near of cam axle 10 installs the cam disc 1;One support supportable rotation axle rod 9 is arranged in parallel on the front side of cam axle 10, and the left end of rotation axle rod 9 has the perpendicular fixed connection of one sliding wiping plate strip 2, and the outer end of sliding wiping plate strip 2 can be connected with the outer circle of cam disc 1, and the right end of axle rod 9 has the perpendicular fixed connection of lever 7, and the front end of lever 7 has the rubber wheel 5 of being able to insert the oil box 4, and the rear end of lever 7 is equipped with the counterweight 8. Both ends of axle rod 9 are supported and connected by bearing seat 6. Counterweight 8 is composed of multiple blocks, and the weight of counterweight 8 can be increased or decreased by bolted connection. The installation position of oil box 4 is about 600mm away from the ground, which is lower than the previous one, and is bolted and installed. Cam disc 1 and cold bed cam 11 are welded to the cold bed cam axle 10 in the same position, to ensure the concentric position of the two cams.

[0015] By the coaxial eccentric principle, a set of cam and lubricating support rod, lubricating rubber wheel are added; when the cooling bed cam 11 makes downward movement, the new cam disc 1 synchronously drives the lubricating lever 7 to immerse the lubricating rubber wheel 5 into the oil box 4, when the cooling bed cam 11 makes upward movement, the new cam disc 1 is synchronously lifted upward under the action of the counterweight 8, drives the rubber wheel 5 of the lubricating lever 7 to contact with the cam 11, transmits the lubricating oil to the cam 11, lubricates the cam 11, the cam 11 is not easy to stick oil and to shake out, is sanitary and does not waste oil, thereby the problem of lubricating the cooling bed is solved.

[0016] When the cooling bed step action, the process of the cooling bed cam 11 action is synchronously reciprocated, thereby the rubber wheel 5 (or lubricating brush) on the lever 7 is reciprocated between the oil box 4 and the cam 11, thereby the purpose of lubricating the cam 11 is achieved.
