Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel bar processing, specifically relates to a straightening and leveling machine. BACKGROUND

[0002] When the steel bar is processed, the straightening and leveling machine needs to be used to realize the stretching bending straightening of the steel bar (blank).

[0003] When the steel bar is straightened and leveled, it needs to be heated to above 500 DEG C, and the steel bar comes out from the discharge roller way, because the temperature of the steel bar is still relatively high, in order to cool the roller, the roller is provided with a water cooling equipment.

[0004] In order to adapt to different models of steel bars, the roller includes fixed rollers and sliding rollers, the power of the sliding rollers comes from the hydraulic cylinder, and the heat of the steel bar is also transferred to the cylinder body of the hydraulic cylinder, and the temperature of the hydraulic cylinder is increased to cause an accident (such as oil leakage). INVENTION CONTENTS

[0005] The utility model solves the technical problem: how to design a straightening and leveling machine roller to reduce the temperature of the hydraulic cylinder.

[0006] The technical scheme of the utility model is specifically as follows:

[0007] A straightening and leveling machine roller, comprising a rack, two vertical plates are fixed on the lower part of the rack, a lower roller is arranged between the two vertical plates, a lower roller shaft of the lower roller is rotatably connected to the two vertical plates, a sliding frame is slidably arranged on the upper part of the rack, an upper roller is arranged in the sliding frame, an upper roller shaft of the upper roller is rotatably connected to the sliding frame, a cylinder body of a hydraulic cylinder is fixed on the top of the rack, the hydraulic cylinder is arranged vertically, a piston end of the hydraulic cylinder is fixed to the sliding frame, an outer cover is fixed to the outer side of the cylinder body, a space between the outer cover and the outer surface of the cylinder body is a sealed cooling water cavity, and a water inlet and a water outlet are arranged on the outer cover.

[0008] The water inlet and the water outlet are arranged on opposite sides of the outer cover.

[0009] Compared with the prior art, the utility model has the technical effect that the cooling water cavity is arranged, and the hydraulic cylinder can be cooled. DRAWINGS

[0010] Figure 1 It is a schematic view of the utility model. CONCRETE IMPLEMENTATION

[0011] The utility model will be described in detail below in combination with the drawings and the concrete implementation.

[0012] As shown in the drawings, Figure 1 A straightening and leveling machine roller, comprising a rack 10, two vertical plates 11 are fixed on the lower part of the rack 10, a lower roller 21 is arranged between the two vertical plates 11, and a lower roller shaft 20 of the lower roller 21 is rotatably connected to the two vertical plates 11.

[0013] The upper part of the frame 10 is slidably provided with a sliding frame 30, and an upper roller 32 is arranged inside the sliding frame 30, and the upper roller shaft 31 of the upper roller 32 is rotatably connected to the sliding frame 30.

[0014] The top of the frame 10 is fixed with a cylinder body 40 of a hydraulic cylinder, and the hydraulic cylinder is arranged up and down, and the piston end 41 of the hydraulic cylinder is fixed to the sliding frame 30, and the outer side of the cylinder body 40 is fixed with an outer cover 42, so that the space between the outer cover 42 and the outer surface of the cylinder body 40 is a sealed cooling water cavity 43, and the outer cover 42 is provided with a water inlet 44 and a water outlet 45.

[0015] In order to make the temperature of the cooling water cavity lower, the water inlet 44 and the water outlet 45 are arranged on opposite sides of the outer cover 42.

[0016] The working principle is as follows:

[0017] When in use, if the steel bar is clamped between the upper roller 32 and the lower roller 21, the normal use is realized. Figure 1

[0018] If it is necessary to change the steel bar of different models, the cylinder body 40 is started, the sliding frame 30 is driven to slide on the frame 10 by the extension and retraction of the piston end 41, and the upper roller 32 is synchronously moved, so that the height between the upper roller 32 and the lower roller 21 is adjusted.

[0019] When in use, the cold water enters the cooling water cavity 43 from the water inlet 44, the cylinder body 40 of the hydraulic cylinder is cooled, the hydraulic oil is also cooled, and finally the hot water is discharged from the water outlet 45.

[0020] Other contents refer to the prior art.

[0021] The above is only the preferred embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, some changes and improvements can be made, which should also be regarded as the protection range of the present application.​
