Steel plate grinding device

This creation relates to a grinding device, and more particularly to a steel plate grinding device that can be used to grind a lower back bearing housing stack plate to improve its accuracy.

The hot rolled steel strip is produced by heating the steel billet to a desired temperature and then rolling it with a rolling mill to form a steel strip. The structure of a conventional rolling mill has two parts, an upper rolling mill and a lower rolling mill, wherein the lower rolling mill is a fixed side and the upper rolling mill is an active side. When rolling the steel strip, the lower rolling mill is not used as a reference to keep the steel strip in the center of the rolling mill, and then use the upper rolling mill to move up and down to adjust the rolling gap.

Since the size of the roll diameter of the work roll and the back roll in the rolling mill affects the level of the steel strip on the rolling mill, a stack liner is placed on the bottom of the lower back roll to adjust the height of the back roll, so each time When replacing the roller, it must be replaced with a calculated stacking plate.

However, the surface of the stacked plate may accumulate scale and oxidized rust. In severe cases, the scale position of the roll may be affected by the scale or the peeling of the oxide layer during the rolling, thereby causing the rolling precision and quality to be degraded. Therefore, it is necessary to grind the stacked plates at intervals to remove scale and rust scale on the surface.

The traditional method of grinding the stacked plates is to place the two long wooden strips on the ground by the operator, and then use the cantilever crane and the wire rope spreader to hang the stacked plates to be ground on the wooden strips. Then, the operator wears personal protective equipment such as safety glasses, gloves, trousers and safety shoes. The hand grinder is matched with the wire wheel or the vegetable melon cloth wheel to remove the scale or rust scale accumulated on the surface of the stacking board. After the grinding is completed, the stacking plate is lifted to the stacking plate storage cabinet for later use.

However, the grinding of the hand-held grinder can generate a large amount of dust, causing environmental and air pollution, affecting the health of nearby workers.

In view of this, there is a need to propose a solution to solve the above problems.

The purpose of this creation is to provide a steel plate grinding apparatus.

Take off.

Referring to FIG. 7, the grinder moving mechanism 400 is used to move the base 310 to enable the reel type forward and backward movement of the drum steel brush wheel 340. The grinder moving mechanism 400 is mainly composed of a motor 410, a reducer 420, a lead screw 430, a track, a limit switch and an electric control box. The actuating system directly drives the lead screw 430 by the motor 410 and the reducer 420, thereby driving the drum steel brush. The wheel 340 performs the action of advancing and retreating. The limit switch set at both ends is matched with the electric control system, so that the steel brush grinder can automatically run back and forth on the track.

In the use of the steel plate grinding apparatus according to the present invention, the steel plate stage 200 is first moved along the stage feed rail 230 to below the table top 110 of the reference stage 100, and then the positioning pin 240 is inserted to lock the steel plate stage 200. The circular hand wheel 222 is then rotated to extend the carrier platform 210 from the opening 120 of the table top 110 and the steel sheet to be ground is placed on the carrier platform 210. The circular hand wheel 222 is then rotated to lower the carrier platform 210 below the table top 110. The ruler 140 is then placed across the table top 110, and the ends of the ruler 140 are placed on the reference block 130, respectively. The circular hand wheel 222 is further rotated to raise the load bearing platform 210 until the upper surface of the steel plate contacts the lower edge of the steel rule 140, that is, the height adjustment of the steel plate processing surface is completed. After the machining height is adjusted, the positioning pin 240 is pulled up, and the steel plate is fed into the grinding zone by the stage feeding rail 230, and the insertion pin is inserted for grinding. The motor 320 is then activated to drive the drum steel brush wheel 340 to rotate, while also initiating the motor 410 to move the drum steel brush wheel 340 back and forth over the steel plate to derust and polish the steel sheet.

When the machining is completed, the bolt is pulled up to pull the steel plate carrier 200 out to the loading area and inserted into the positioning pin 240 to be fixed. After that, the steel plate is lifted to be turned over or replaced, and the next processing is performed.

According to the steel plate grinding apparatus of the present invention, the adjusting screw 391 of the grinder 300 is pressed against the lower steel plate 311 of the base 310, and then the rear end of the upper steel plate 312 is lifted upward by the front end hinge 380, and further The extension arm 330 fixed to the front end and the roller steel brush wheel 340 are pressed downward to compensate for the loss of the roller steel brush wheel 340 during the rust polishing work. When the adjusting screw 391 is adjusted, the nut 396 on the locking screw 395 can be locked downward to tighten the upper steel plate 312 by the downward pressure of the nut locking to avoid vibration and the adjusting screw 391 is loose. Take off. In addition, the limit switch disposed at both ends is matched with the electronic control system, so that the roller steel brush wheel 340 can automatically run back and forth on the track 370, thereby achieving the purpose of reciprocating grinding and polishing.

Since some rust can not be cleaned when the surface of the steel plate is slightly unilaterally worn, the present invention sets the track 370 to be able to individually adjust its position height to change the left and right inclination angle of the roller steel brush wheel 340 during grinding and cleaning. This will remove the rust on the surface of the steel sheet. In addition, in order to prevent the abrasive debris from eroding the environment and injuring people when the machine is running, a splash-proof cover can be provided to block the splash. Since the rust removal stroke is long and needs to be completely sealed, the size of the splash guard cover is relatively large. In order to facilitate the operation of the personnel without affecting its functionality, the splash-proof cover can be designed with a squat design and divided into two pieces to reduce the weight. At the same time, a single-piece upper sill can be opened at the position behind the adjustment mechanism of the grinder. Small door for easy adjustment.

The adjustable steel plate carrier can use the steel ruler as the height reference line, adjust the height for the thickness of the steel plate, and align the upper surface of the steel plate with the reference line, so that the surface of the steel plate can be fully ground by the roller steel brush wheel. The adjustment mechanism is mainly constructed to save time and effort when the steering gear is operated.

The width of the drum steel brush wheel of the grinder is just the width of the steel plate, so the entire steel plate surface can be covered once per movement, and the grinding is not required, which can save working time and maintain grinding precision. In addition, the grinder is provided with a fine adjustment mechanism. When the steel brush is worn, the fine adjustment mechanism is used for adjustment so that the steel brush can maintain the contact pressure with the workpiece while maintaining the grinding force.

The moving mechanism of the grinder drives the grinding screw directly on the rail by the motor and the reducer, and the limit switch is installed on the front and rear of the rail to control the advance and retreat of the grinder. In addition, the track can also be fine-tuned with the steel plate.

The person does not need to use a hand grinder for the grinding operation, and the splash-proof cover can effectively block the spatter during the operation and improve the safety of the work.

The anti-splash protection cover can effectively block the dust generated during grinding, reduce the pollution of the ambient air, and greatly improve the working environment.
