Description

Technical Field

[0001] This utility model relates to the field of spraying auxiliary equipment technology, specifically an auxiliary adjustment mechanism for roller spraying. Background Technology

[0002] Rolls are the main working parts and tools on rolling mills that cause continuous plastic deformation of metal. Rolls are mainly composed of three parts: roll body, roll neck and shaft head.

[0003] During the rolling process, the surface of the roll and the rolled product come into contact and rub against each other, and the rolls must withstand strong friction and extrusion forces. Therefore, during the production process, the surface of the rolls usually needs to be coated with tungsten carbide thermal spraying to strengthen it. During the spraying process, the two ends of the roll are typically held in place by a three-jaw chuck and driven to rotate by a motor. However, this method has some functional limitations in practical use and has room for improvement. For example, rolls vary in size and weight. Adjusting the roll by rotating the chuck is suitable for light rolls, but inadequate for heavy rolls. The roll needs to be hoisted and adjusted to the chuck position, and then the chuck head needs to be manually adjusted and engaged. This operation is time-consuming and carries certain safety risks, and it lacks a convenient placement and adjustment function.

[0004] Now, a novel auxiliary adjustment mechanism for roll coating is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary adjustment mechanism for roller coating, so as to solve the problem mentioned in the background art that it does not have the function of easy placement and adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary adjustment mechanism for roller coating, comprising a bottom fixing frame, T-shaped slide rails being horizontally fixedly connected to the front and rear ends of the top of the bottom fixing frame, two sets of concave fixing seats being provided above the bottom fixing frame, a steel sleeve being welded to the top of the concave fixing seats, an extension sleeve being inserted into the inside of the steel sleeve from top to bottom, concave wheel seats being fixedly connected to the front and rear ends of the top of the extension sleeve, a support wheel being movably connected inside the concave wheel seat, a reduction motor being fixedly connected to the bottom of the inner side of the concave wheel seat, a commutator being installed at the top of the inner side of the concave wheel seat, a controller being fixedly connected to the outer side of the steel sleeve, a first electric cylinder being installed at the front and rear ends of the inside of the extension sleeve, a second electric cylinder being fixedly connected to the front and rear ends of the inside of the concave fixing seat, side plates being fixedly connected to the left and right sides of the bottom fixing frame, and sliders being fixedly connected to the front and rear ends of the bottom of the concave fixing seat.

[0007] As a further technical solution of this utility model, the concave wheel seat is symmetrically distributed about the vertical center line of the extension sleeve, and the vertical center lines of the concave fixing seat, the steel sleeve, and the extension sleeve coincide.

[0008] As a further technical solution of this utility model, the output end of the geared motor is connected to the input end of the commutator, the output end of the commutator is connected to the support wheel, and the geared motor and the controller are electrically connected.

[0009] As a further technical solution of this utility model, the shape and size of the outer part of the extended sleeve are adapted to the shape and size of the inner part of the steel sleeve, and the extended sleeve can slide up and down along the inside of the steel sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the auxiliary adjustment mechanism for roller coating not only realizes the function of easy placement and adjustment, but also the function of easy adjustment of roller height and the function of easy adjustment of support position;

[0013] (1) By setting up a concave wheel seat, a support wheel, a commutator and a geared motor, when in use, the roll is hoisted to the top of the concave wheel seat by the hoisting equipment and slowly lowered. Two sets of support wheels on the left and right sides support the roll neck. During the thermal spraying process, the geared motor drives the support wheel to rotate slowly and uniformly through the commutator. The support wheel then drives the roll to rotate slowly and uniformly, so that the spraying is uniform. There is no need for too much manual adjustment during the placement process, which realizes the function of easy placement and adjustment.

[0014] (2) By setting up a steel sleeve, an extension sleeve and a first electric cylinder, the actual position height of the roll can be adjusted according to the thickness of the roll and the spraying requirements.

It can adapt to rollers of different lengths and realize the function of easy adjustment of the support position. Attached Figure Description

[0023] The concave wheel seat 6 is symmetrically distributed about the vertical center line of the extension sleeve 5. The vertical center lines of the concave fixed seat 3, the steel sleeve 4, and the extension sleeve 5 coincide. The output end of the geared motor 9 is connected to the input end of the commutator 8. The output end of the commutator 8 is connected to the support wheel 7. The geared motor 9 and the controller 10 are electrically connected, which facilitates placement and support without much adjustment.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the geared motor 9 drives the support roller 7 to rotate slowly and uniformly through the commutator 8. The support roller 7 then drives the roller to rotate slowly and uniformly, so that the coating is uniform. No manual adjustment is required during the placement process.

The output end of the first electric cylinder 11 is fixedly connected to the bottom end of the inside of the steel housing 4. The controller 10 and the first electric cylinder 11 are electrically connected.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, when the first electric cylinder 11 extends or retracts, it can push the extension sleeve 5 to slide up and down along the inside of the steel sleeve 4 through the reaction force. The height of the concave wheel seat 6 and the supporting wheel 7 will change, and the height of the roller will change.

[0029] Working principle: When using this utility model, firstly, the roller is hoisted to the concave wheel seat 6 by the hoisting equipment and slowly lowered. Two sets of support rollers 7 on the left and right sides support the roller neck. During the thermal spraying process, the reduction motor 9 drives the support rollers 7 to rotate slowly and uniformly through the commutator 8. The support rollers 7 then drive the roller to rotate slowly and uniformly, so that the spraying is uniform. No excessive manual adjustment is required during the placement process.

[0030] Depending on the thickness of the roll and the coating requirements, the actual position and height of the roll can be adjusted. The first electric cylinder 11 extends or retracts, and the reaction force pushes the extension sleeve 5 to slide up and down along the inside of the steel sleeve 4. The height of the concave wheel seat 6 together with the support wheel 7 changes, and the height of the roll changes accordingly.

[0031] Depending on the length of the roll and the coating requirements, the position of the concave wheel seat 6 and the supporting wheel 7 can be adjusted. The second electric cylinder 12 can extend or retract, and through the reaction force with the side plate 13, the concave fixed seat 3 and the slider 14 can be pushed to slide along the T-shaped slide rail 2, which can accommodate rolls of different lengths.
