Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel processing, in particular to a slab grinding machine. Background Art

[0002] The slab grinding machine is mainly used for the grinding of various types of steel ingots and continuous casting billets, and the grinding of forged billets and continuous casting billets. The steel types involved include titanium and titanium alloys, high-temperature alloys, corrosion-resistant alloys, precision alloys, special stainless steels and ordinary stainless steels. The slab grinding machine generally includes many components such as a loading platform, a horizontal grinding machine, a grinding trolley, a billet turning device, and a unloading platform. When the existing slab grinding machine is grinding the slab, due to the coarse slab debris of materials such as stainless steel slabs, a large amount of high-temperature grinding debris will be generated in the horizontal direction during grinding. In order to prevent this high-temperature grinding debris from directly entering the grinding debris collection box and causing damage to the box wall, a water-cooled baffle is usually set in the protective cover. The water-cooled baffle is made of a double-layer steel plate plus a partition, and a cooling water circulation is arranged inside it to prevent the grinding debris from penetrating the guard plate and the grinding debris and dust from bonding and gathering. The water-cooled baffle is an R-shaped 90° guard plate, which can effectively block the grinding debris when the grinding wheel changes the angle. The problem with this structure is that the high-temperature grinding chips easily form agglomerates on the surface of the water-cooled baffle and then fall into the grinding chip collection box, which requires an additional process to crush the agglomerated grinding chips into powder for recycling, thereby increasing the processing cost. Therefore, how to develop a new slab grinding machine to overcome the above problems in the prior art is a direction that technicians in this field need to further study. Utility Model Content

[0003] The utility model aims to provide a slab grinding machine, which can reduce the phenomenon that grinding chips form agglomerates and enter a grinding chip collection box, thereby avoiding the process of re-crushing the agglomerated grinding chips and reducing the processing cost.

[0004] The utility model discloses a slab grinding machine, which comprises:

[0005] A first track, wherein the first track is fixedly installed in a groove on the workshop floor, and a first moving trolley is installed on the first track, wherein the first moving trolley is configured to load stainless steel slabs;

[0006] A grinding mechanism, the grinding mechanism comprising a vertical plate arranged on one side of the first track, and a horizontal plate having one end connected to the top of the vertical plate and the other end extending to the top of the first track; a grinding wheel is installed on the lower side of the horizontal plate;

[0007] A grinding chip baffle assembly, the grinding chip baffle assembly comprising two side baffles and an oblique guide plate; the two side baffles are symmetrically installed on the left and right sides of the horizontal plate and the vertical plate; the oblique guide plate is arranged between the two side baffles, the upper end surface of the oblique guide plate is connected to the lower side surface of the horizontal plate, and the lower end surface of the oblique guide plate is connected to the side of the vertical plate facing the grinding wheel;

[0008] A collecting funnel, the collecting funnel is arranged directly below the oblique guide plate; the large mouth end of the collecting funnel is arranged directly opposite to the oblique guide plate; a plurality of cooling fans are symmetrically distributed on the side wall of the collecting funnel;

[0009] A wear debris collection box is arranged below the small mouth end of the collecting funnel, and a wear debris inlet is arranged on the top of the wear debris collection box.

[0010] By adopting this technical solution: the stainless steel slab to be processed is placed on the first moving trolley, and the first moving trolley is driven to move along the first track to the processing station. When the first moving trolley moves to the processing station. The grinding wheel is started to grind the surface of the stainless steel slab to be processed. During this grinding process, high-temperature abrasive chips are generated on the surface of the stainless steel slab. These high-temperature abrasive chips splash along the friction angle between the surface of the stainless steel slab and the grinding wheel to the lower side of the plate body of the inclined guide plate, and then fall from the lower side of the plate body of the inclined guide plate under the action of gravity; the fallen high-temperature abrasive chips first enter the large mouth end of the collecting funnel, and then enter the abrasive chip collection box from the small mouth end after being gathered. At the same time, the cooling fan on the collecting hopper is started to cool down the high-temperature abrasive chips that slide down from the collecting funnel, and the cooled high-temperature abrasive chips enter the abrasive chip collection box. Therefore, this solution does not need to set up an inner lining circulating water cooling on the inclined guide plate to prevent the high-temperature chips from directly entering the chip collection box and causing damage to the box wall. Since condensation will not occur on the surface of the inclined guide plate, the problem of high-temperature chips agglomerating under the action of water cooling is overcome, thereby avoiding the process of re-crushing the agglomerated chips and reducing processing costs.

[0011] Preferably, the side baffles and the oblique guide plates are respectively made of heat-resistant stainless steel plate blanks.

[0012] By adopting this technical solution, the damage to the wear baffle assembly caused by the flying high-temperature wear debris can be overcome, thereby extending the service life of the wear baffle assembly.

[0013] Preferably, the upper end surface of the plate body of the oblique guide plate is connected to the horizontal plate by a first polished rod screw, and there is a first gap between the upper end surface of the plate body of the oblique guide plate and the horizontal plate; the lower end surface of the plate body of the oblique guide plate is connected to the vertical plate by a second polished rod screw, and there is a second gap between the lower end surface of the plate body of the oblique guide plate and the vertical plate.

[0014] By adopting this technical solution: during the processing of grinding the material surface, when the flying high-temperature abrasive chips hit the surface of the inclined guide plate, the inclined guide plate will produce corresponding vibrations, thereby causing some of the high-temperature abrasive chips attached to the surface of the inclined guide plate to fall under the action of the vibration, thereby reducing the situation where the high-temperature abrasive chips adhere to the surface of the inclined guide plate.

[0015] Preferably, it also includes: a second track, the second track is fixedly installed in a groove on the workshop floor, the second track can be set to be parallel / perpendicular to the first track, a second mobile trolley is movably installed on the second track, and the grinding chip collection box is arranged on the second mobile trolley.

[0016] By adopting this technical solution: the second moving trolley moves along the second track to the material receiving station, so that the grinding chip inlet moves to the bottom of the small end of the collecting funnel, and receives the grinding chips output from the collecting funnel. After being filled, the second moving trolley moves away from the material receiving station with the grinding chip collection box to complete the unloading of the grinding chips.

[0017] Preferably, the inclined guide plate has an inclination angle of 45°-70°.

[0018] Compared with the prior art, the utility model has the following technical advantages:

[0019] Firstly, the utility model can reduce the phenomenon that the agglomerates of the grinding chips enter the grinding chip collection box, thereby avoiding the process of crushing the agglomerated grinding chips again, and reducing the processing cost.

[0021] Finally, the utility model has a simple structure and is easy to prepare and implement. BRIEF DESCRIPTION OF THE DRAWINGS

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0027] Example 1, please refer to Figure 1-2 :

[0028] A slab grinding machine comprises: a first track 100 , a grinding mechanism 200 , a wear chip baffle assembly, a collecting funnel 500 , a wear chip collecting box 600 , and a second track 620 .

[0029] The first track 100 is fixedly installed in a groove on the floor of the workshop, and a first moving trolley 110 is installed on the first track 100. The first moving trolley 110 is configured to load the stainless steel slab 700;

[0030] The grinding mechanism 200 includes a vertical plate 210 disposed on one side of the first track 100, and a horizontal plate 220 having one end connected to the top of the vertical plate 210 and the other end extending to the top of the first track 100; a grinding wheel 300 is mounted on the lower side of the horizontal plate 220;

[0031] The grinding chip baffle assembly includes two side baffles 420 and an oblique guide plate 410; the two side baffles 420 are symmetrically installed on the left and right sides of the horizontal plate 220 and the vertical plate 210; the oblique guide plate 410 is arranged between the two side baffles 420, the upper end surface of the oblique guide plate 410 is connected to the lower side surface of the horizontal plate 220, and the lower end surface of the oblique guide plate 410 is connected to the side of the vertical plate 210 facing the grinding wheel 300. Specifically, the upper end surface of the oblique guide plate 410 is connected to the horizontal plate 220 through a first polished screw 431, and there is a first gap between the upper end surface of the oblique guide plate 410 and the horizontal plate 220; the lower end surface of the oblique guide plate 410 is connected to the vertical plate 210 through a second polished screw 432, and there is a second gap between the lower end surface of the oblique guide plate 410 and the vertical plate 210. The oblique guide plate 410 has an inclination angle of 45°-70°.

[0032] The collecting funnel 500 is arranged directly below the oblique guide plate 410; the large opening end of the collecting funnel 500 is arranged directly opposite to the oblique guide plate 410; a plurality of cooling fans 10 are symmetrically distributed on the side wall of the collecting funnel 500;

[0033] The wear debris collection box 600 is arranged below the small opening of the collection funnel 500, and a wear debris inlet is arranged at the top of the wear debris collection box 600. Specifically, the second track 620 is fixedly installed in a groove on the workshop floor and is parallel to the first track 100 (in practice, the second track 620 can also be arranged to be perpendicular to the first track 100). A second moving trolley 610 is movably installed on the second track 620, and the wear debris collection box 600 is arranged on the second moving trolley 610. The second moving trolley 610 moves along the second track 620 to move the wear debris collection box 600 to the small opening of the collection funnel 500 or move it away.

[0034] In practice, the working process is as follows:

[0035] The stainless steel slab 700 to be processed is placed on the first moving trolley 110, and the first moving trolley 110 is driven to move to the processing station along the first track 100. At the same time, the second moving trolley 610 is driven to move along the second track 620 until the wear chip collection box 600 moves to the small end of the collecting funnel 500. When the first moving trolley 110 moves to the processing station. The grinding wheel 300 starts to grind the surface of the stainless steel slab 700 to be processed. During this grinding process, high-temperature wear chips are generated on the surface of the stainless steel slab 700. These high-temperature wear chips splash along the friction angle between the surface of the stainless steel slab 700 and the grinding wheel 300 to the lower side of the plate body of the oblique guide plate 410, and then fall from the lower side of the plate body of the oblique guide plate 410 under the action of gravity; the falling high-temperature wear chips first enter the large end of the collecting funnel 500, gather and enter the wear chip collection box 600 from the small end. At the same time, the cooling fan 10 on the collection hopper is started to cool down the high-temperature wear debris sliding down from the collection funnel 500, and the cooled high-temperature wear debris enters the wear debris collection box 600 for collection. Therefore, this solution does not need to set a lining circulating water cooling on the inclined guide plate 410 to avoid the high-temperature wear debris directly entering the wear debris collection box 600 and causing damage to the box wall. Since the plate surface of the inclined guide plate 410 does not produce condensation, the high-temperature wear debris is overcome. The agglomeration of the water cooling is avoided, and the process of crushing the agglomerated wear debris again is avoided, thereby reducing the processing cost.

[0036] In this example, the side baffle plate 420 and the oblique guide plate 410 are respectively made of heat-resistant stainless steel plate blanks 700.

[0037] It should be noted that in this solution: the first track 100, the first moving trolley 110, the support frame, the grinding wheel 300 and the grinding chip collection box 600 are all mature existing products. The specific structures and interconnection relationships of the first track 100, the first moving trolley 110, the support frame, and the grinding wheel 300 are all mature technologies in the field. The working principles of the second track 620 and the second moving trolley 610 are similar to those of the first track 100 and the first moving trolley 110, so they will not be described in detail in this article.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
