Description

Technical Field

[0001] The utility model relates to the field of fire extinguisher racks, in particular to a fire extinguisher rack bending device. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. Chemicals are placed in the fire extinguisher to put out fires. Fire extinguishers are one of the most common firefighting equipment and are stored in public places or places where fires may occur. Different types of fire extinguishers are filled with different ingredients and are designed for different causes of fire. Be careful when using them to avoid adverse effects and dangers.

[0003] In actual application, fire extinguishers need to be used with a hanger in some cases, that is, the hanger is used to carry the fire extinguisher so that it can be hung at a suitable height and position for easy access when used. Traditional fire extinguisher hangers are mostly composed of a back plate and two rings fixed on the back plate, and the rings need to be bent when used. Conventional bending methods are mostly manual bending. However, in actual use, it is found that due to the certain strength of the plate, manual bending alone is relatively strong, which is not conducive to mass production.

[0004] Therefore, we make improvements to this and propose a fire extinguisher rack bending device. Utility Model Content

[0013] As a preferred technical solution of the present application, a bending groove is formed on the surface of the bending disk, and a bending space is formed between the bending groove and the two abutting columns.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the scheme of this application:

[0016] By setting up a bending unit, the plate is placed on one side of the bending disk and the servo motor is started to drive the two gears to rotate synchronously.

[0032] like Figure 1-Figure 4 As shown, this embodiment provides a fire extinguisher rack bending device, comprising a support frame 1 and a bending plate 11 fixed on the support frame 1, a bending unit 2 for resisting and bending the fire extinguisher rack is provided above the bending plate 11, and an adjusting unit 3 for driving the bending unit 2 to adjust the height is also provided on the support frame 1;

[0033] The bending unit 2 includes a bearing seat 21 and a gear 22 disposed above the bearing seat 21 through a bearing, wherein the gear 22 has two gears that mesh with each other, and the two gears 22 can rotate relative to the surface of the bearing seat 21. The surfaces of the two gears 22 are fixed with swing arms 23 for connecting with the abutment column 24. A servo motor 25 is disposed above the bearing seat 21 and is in transmission cooperation with one of the gears 22.

[0034] The two gears 22 are symmetrically distributed about the center of the bending disk 11, so that during the mutual meshing and rotation, the swing arms 23 thereon can drive the abutment posts 24 to slide synchronously close to the outer circumference of the bending disk 11, thereby forming an abutment bending of the plate;

[0035] The adjustment unit 3 includes an adjustment portion 31 and a connection portion 32. The connection portion 32 includes a connection arm 320 fixed to the surface of the servo motor 25. The connection arm 320 is partially connected to the surface of the bearing seat 21. An end of the connection arm 320 away from the servo motor 25 is connected to an adjustment plate 321.

[0036] The adjusting part 31 includes an adjusting screw rod 322 threadedly penetrated at both ends of the adjusting plate 321, one end of the adjusting screw rod 322 is connected to an adjusting motor 323 fixed to the top of the support frame 1, and the other end of the screw rod 322 is movably assembled to the bottom wall of the support frame 1 through a bearing, and the adjusting motor 323 is started to drive the screw rod 322 to rotate, and the screw rod 322 and the corresponding adjusting plate 321 can be assembled by thread, so that the adjusting plate 321 can slide along the height direction of the support frame 1, so as to adjust the height of the bending unit 2, so as to facilitate the removal of the round plate after bending;

[0037] A bending groove 12 is formed on the surface of the bending disk 11, and a bending space is formed between the bending groove 12 and the two abutting pillars 24;

[0038] By setting the bending groove 12, the plate can be partially placed in the bending groove 12 during the actual bending process to maintain stability during the bending process and is not prone to falling. At the same time, since the inner diameter of the plate after bending may be slightly smaller than the size of the bending groove 12, the plate can be opened at a certain distance at the opening of the bent plate, and the plate can be taken out for the preparation of the fire extinguisher hanger, which will not affect the use of the prepared circular plate.

[0039] When bending the circular ring required for preparing the fire extinguisher, the plate to be bent is placed on the surface of the bending disk 11. At this time, the plate is located between the resistance column 24 and the bending groove 12 on the bending disk 11. At this time, the servo motor 25 is started to drive the gear 22 at its output end to rotate. Since the two gears 22 are in a state of mutual meshing, the two gears 22 will synchronously drive the swing arms 23 thereon to rotate in the opposite direction. The two swing arms 23 will synchronously drive the resistance column 24 to move, so that the resistance column 24 slides along the outer circumferential direction of the bending disk 11 and finally forms a resistance bending on the plate. When the plate is bent, the adjusting motor 323 is started to drive the adjusting screw rod 322 to rotate. Through the threaded cooperation between the adjusting screw rod 322 and the corresponding adjusting plate 321, the bending unit 2 will be driven to rise and fall in height through the connecting arm 320, so that the resistance column 24 is lifted above the bent plate. At this time, the plate can be taken out from the surface of the bending disk 11.

[0040] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
