Description

Technical Field

[0001] This utility model relates to the field of steel cabinet processing, and in particular to a steel cabinet production sheet grinding device. Background Technology

[0002] In the production process of steel cabinets, steel coils are usually cut into sheets of the required size after being flattened. The sheets are then bent, welded and assembled to form steel cabinets.

[0003] However, when cutting sheet metal, a stamping machine is usually used for rapid cutting, which makes the edges of the sheet metal sharp and burrs protrude. This makes it difficult for the sides to fit tightly during welding, resulting in incomplete welds. In the existing process, the sides of the sheet metal need to be ground. For thicker sheets, one side needs to be ground twice, and both sides need to be ground, for a total of four grinding operations. This makes the entire grinding process more time-consuming. Moreover, the grinding process requires operators to position and clamp the sheet metal, which is very troublesome. Therefore, a sheet metal grinding device for steel cabinet production is provided. Utility Model Content

[0004] The purpose of this invention is to provide a steel plate grinding device for steel cabinet production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel cabinet production plate grinding device, including a grinding table and a grinding mechanism installed on the grinding table. A driving component is installed in the middle of the grinding table. The grinding mechanism includes a grinding positioning seat and grinding chambers opened at both ends of the grinding positioning seat. An inclined abrasive belt grinding component and a positioning roller are respectively arranged inside the two ends of the grinding chamber. The inclined abrasive belt grinding component and the positioning roller at both ends are staggered vertically. The driving component pushes the two sides of the plate through the grinding chamber, so that the sides of the plate are ground by the two sets of inclined abrasive belt grinding components, with the upper and lower edges ground sequentially. The positioning rollers are used for positioning during grinding.

[0006] Preferably, the positioning roller is perpendicular to the surface of the grinding table.

[0007] Preferably, the beveled belt sander includes a belt sander and a fixed base fixedly installed on the outer wall of the belt sander. A through bolt is installed between the fixed base and the belt sander, and the fixed base is movably installed in the sanding chamber.

[0008] Preferably, a positioning shaft is fixedly welded to the fixed seat, and a support part is installed on the side wall of the grinding chamber by screws. The positioning shaft passes through the support part, and a memory spring is movably sleeved on the outer wall of the inner end of the positioning shaft.

[0009] Preferably, the belt sander is set at an angle, and the front end of the belt sander is tilted outward, so that the distance between the feed ends of the two sets of belt sanders set on opposite sides is large and the distance between the discharge ends is small.

[0010] Preferably, the driving component includes a chain installed inside the grinding table and a pusher block fixedly installed on the outer wall of the chain. The top of the grinding table is provided with a sliding groove, and the pusher block slides along the sliding groove when it moves with the chain.

[0011] Preferably, the grinding table has a sprocket rotatably mounted inside, the chain is mounted on the sprocket, and a drive motor for driving the sprocket to rotate is fixedly mounted on the outer wall of the grinding table.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By placing the steel plate on the grinding table and starting the drive motor, the chain drives the pusher block into the chute, pushing the steel plate into the grinding positioning seat. The two sides of the steel plate enter the two grinding chambers respectively. At this time, the lower edges of the two sides of the steel plate are close to the belt sanders on both sides of the feeding end. Due to the "wider in front and narrower in back" design of the relative spacing between the two sets of belt sanders, the closer the steel plate moves inward, the greater the compression force of the memory spring, thus enabling the belt sanders to grind the lower edges of the steel plate on both sides. Then, the front end of the steel plate enters between the two sets of belt sanders at the feeding end. At this time, the upper edges of the two sides of the steel plate are ground by the two sets of belt sanders at the discharging end. The whole process is continuous and automatic, grinding the four edges on both sides, which is fast and does not require manual positioning. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1 to 4 The steel cabinet production plate grinding device shown includes a grinding table 1 and a grinding mechanism 3 installed on the grinding table 1. A driving component 2 is installed in the middle of the grinding table 1. The grinding mechanism 3 includes a grinding positioning seat 31 and grinding chambers 32 opened at both ends of the grinding positioning seat 31. The grinding chambers 32 are respectively provided with beveled abrasive belt grinding components 33 and positioning rollers 34 at both ends. The beveled abrasive belt grinding components 33 and positioning rollers 34 at both ends are staggered vertically. The driving component 2 pushes the two sides of the plate through the grinding chambers 32 so that the sides of the plate are ground by the two sets of beveled abrasive belt grinding components 33 successively on the upper and lower edges. The plate is positioned by the positioning rollers 34 during grinding.

[0021] The positioning roller 34 is perpendicular to the surface of the grinding table 1, thereby ensuring that the steel plate is in close contact with the grinding table 1 when the steel plate is fed, and avoiding skewing.

[0022] The beveled belt sander 33 includes a belt sander 331 and a fixed seat 332 fixedly installed on the outer wall of the belt sander 331. A through bolt 333 is installed between the fixed seat 332 and the belt sander 331. The fixed seat 332 is movably installed in the sanding chamber 32. The belt sander 331 includes a bracket and two sanding belt wheels that rotate inside the bracket. A sanding belt is installed between the sanding belt wheels. A sanding motor for driving the sanding belt wheels to rotate is fixed on the outer wall of the bracket.

[0023] A positioning shaft 335 is fixedly welded onto the fixed base 332. A support part 334 is installed on the side wall of the grinding chamber 32 by screws. The positioning shaft 335 passes through the support part 334, and a memory spring 336 is movably sleeved on the outer wall of the inner end of the positioning shaft 335 so that the belt sander 331 can remain in close contact with the steel plate.

[0024] The belt sander 331 is set at an angle of 45 degrees, and the front end of the belt sander 331 is tilted outward so that the distance between the feed ends of the two sets of belt sanders 331 set opposite each other on both sides is large and the distance between the discharge ends is small. This makes it easier for the steel plate to enter between the two opposite belt sanders 331. At the same time, the closer the steel plate moves inward, the greater the squeezing force of the memory spring 336, so that the belt sander 331 can grind the lower edges of both sides of the steel plate.

[0025] The driving component 2 includes a chain 21 installed inside the grinding table 1 and a pusher 24 fixedly installed on the outer wall of the chain 21. The top of the grinding table 1 has a slide groove 12. When the pusher 24 moves with the chain 21, it slides along the slide groove 12. A sprocket 22 is rotatably installed inside the grinding table 1. The chain 21 is installed on the sprocket 22. A drive motor 23 for driving the sprocket 22 to rotate is fixedly installed on the outer wall of the grinding table 1. When the drive motor 23 is started, the sprocket 22 drives the chain 21 to move. The chain 21 drives the pusher 24 into the slide groove 12. The pusher 24 pushes the steel plate along the slide groove 12 into the grinding positioning seat 31. At this time, the two sides of the steel plate enter the two grinding chambers 32 respectively.

[0026] Working principle: When using this device, the steel plate to be ground is placed on the grinding table 1, the drive motor 23 is started, the sprocket 22 drives the chain 21 to move, the chain 21 drives the push block 24 into the slide groove 12, and the push block 24 pushes the steel plate along the slide groove 12 into the grinding positioning seat 31. At this time, the two sides of the steel plate enter the two grinding chambers 32 respectively. The steel plate is first pressed and positioned downward by the positioning roller 34 at the top, so that the lower edges of the two sides of the steel plate are close to the belt sanders 331 on both sides of the feed end. Due to the "wider in front and narrower in back" design of the relative spacing between the two sets of belt sanders 331, the steel plate moves inward as it moves further inward. The greater the pressure from the memory spring 336, the more the belt sander 331 grinds the lower edges of both sides of the steel plate. Then, the front end of the steel plate enters between the two sets of belt sanders 331 at the feeding end. At this time, the steel plate is supported by the positioning roller 34 at the bottom, so that the steel plate is close to the two sets of belt sanders 331 at the discharge end, thereby achieving grinding of the upper edges of both sides of the steel plate. The entire process is continuous and automatic, grinding of the four edges on both sides. The grinding cycle and grinding speed can be adjusted by adjusting the speed of the belt sander 331 and the speed of the drive motor 23. By extending the grinding time, the grinding depth and effect can be improved.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
