[0001] The invention relates to the technical field of pipe bending, in particular to a pipe bending auxiliary device and a method for manufacturing a grinding tool. Background Art

[0002] During the steel pipe bending operation, the steel pipe is relatively long. During the operation, the worker operating the pipe bender can only control a part of the steel pipe placed on the pipe bender.

Therefore, two workers are usually required to complete the work at the same time. The process is more troublesome, and during the operation, the worker holding the other end of the steel pipe needs to overcome the swing resistance brought by the bending process. Therefore, the overall operation process is very cumbersome. Summary of the invention

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and this embodiment provides a pipe bending auxiliary device, including a support assembly 100, which includes a table body 101, a bracket 102 arranged on the upper end surface of the table body 101, and a lifting member 103 in contact with the bottom of the table body 101, a pipe bending assembly 200, which cooperates with the end surface of the table body 101, and includes two groups of fixed disks 201, a push plate 202 arranged between the two groups of fixed disks 201, a pressure component 203 arranged on the side of the push plate 202 away from the fixed disk 201, and a sliding component 204 arranged on one side of the fixed disk 201, the bracket 102 is provided with a plurality of groups cooperating with the pipe bending assembly 200, the bracket 102 contacts the fixed disk 201 to form a support, and the bracket 102 forms a sliding fit with the pressure component 203.

[0031] Furthermore, a plurality of adjustment holes 201a are symmetrically provided at corresponding positions on the surfaces of the two groups of fixed disks 201; a support platform 201b is fixedly provided on the side of the bottom fixed disk 201 close to the pressurizing component 203, and a through hole 201b-1 is provided on the support platform 201b. The bending pipe assembly 200 also includes two groups of deformation columns 205, and both ends of the deformation columns 205 are respectively inserted into the adjustment holes 201a corresponding to the two groups of fixed disks 201, and a first bending groove 205a is provided at the mating end of the deformation column 205 and the pressurizing component 203.

[0032] Furthermore, a second curved groove 202a is provided at the mating end of the push plate 202 and the deformation column 205, and the pressurizing component 203 includes a hydraulic cylinder 203a, which is plugged into and mated with the other end of the push plate 202 through the through hole 201b-1. The pressurizing component 203 also includes a pressurizing handle 203b arranged at the other end of the hydraulic cylinder 203a, and the pressurizing handle 203b controls the hydraulic cylinder 203a to pressurize. A pulley 203c is provided at one end of the hydraulic cylinder 203a close to the bracket 102, and the pulley 203c is slidably mated with the bracket 102.

[0033] Specifically, the displacement of the overall height of the table body can be controlled by the lifting member 103 to achieve a comfortable height, so that the staff can perform more comfortable operations. The lifting member 103 is driven by hydraulic pressure to drive the internal rise and fall. First, a set of fixed plates 201 are placed at the bottom, and then two sets of deformation columns 205 are inserted into the adjustment holes 201a on the fixed plates 201. Note that during the installation of the deformation columns 205, the deformation columns 205 can be placed in the required adjustment holes 201a according to needs. Every two adjustment holes The hole 201a corresponds to a shape of the curvature of the pipe bend. The push plate 202 is plugged into the output end of the hydraulic cylinder 203a to ensure the stability of the push plate 202 during the pressurization process. The steel pipe is placed between the two sets of fixed plates 201. By applying force to the pressurization handle 203b, the hydraulic cylinder 203a is controlled to push the push plate 202. The second bending groove 202a on the push plate 202 contacts the steel pipe, causing the steel pipe to displace and contact the first bending grooves 205a on the two sets of deformation columns 205. The steel pipe is squeezed on both sides to bend, thereby achieving the effect of bending the pipe.

[0034] Example 2

[0035] Reference Figure 1 to Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, it also includes a sliding component 204 including an arc slide 204a fixedly set on the surface of the bracket 102 at one end cooperating with the fixed plate 201, and a sliding member 204b is slidably set in the arc slide 204a. The sliding member 204b includes a sliding column 204b-1 sliding in the arc slide 204a and a rotating ball 204b-2 fixedly set at one end of the sliding column 204b-1 away from the arc slide 204a, and the rotating ball 204b-2 is provided with a through groove.

[0036] Furthermore, the curvature of the arc slide 204a is the same as that of the second curved groove 202a, the travel angle of the arc slide 204a is 90°, the arc slide 204a is centered at the midpoint of the two groups of deformation columns 205, and the starting end of the arc slide 204a is close to one side of the deformation column 205.

[0037] Specifically, when the steel pipe is placed on the fixed plate 201, the other end can pass through the through slot on the rotating ball 204b-2, and the rotating ball can rotate 180 degrees. When the steel pipe is deviated during the extrusion process, the rotating ball can rotate accordingly. The arc slide 204a is formed into an arc track 204a with the midpoint of the two sets of deformation columns 205 as the center. At this time, assuming that the distance between the two sets of deformation columns 205 is n, then the radius of the arc track 204a is as follows: Figure 5As shown, n+500mm is the maximum bending limit of the steel pipe. Therefore, setting the radius of the arc track 204a to n+500mm can not only limit the maximum bending limit of the steel pipe, but also ensure that if bending is impossible, the other end of the steel pipe will not contact the rotating ball 204b-2 when it is installed on the fixed plate 201. At this time, bending work can no longer be performed, avoiding the phenomenon of steel pipe bursting due to the staff's fluke mentality of trying, which poses a serious safety hazard.

[0038] In summary, in the pipe bending process, the steel pipe needs to be first passed through the through groove of the rotating ball 204b-2. The initial position of the rotating ball 204b-2 should be kept in line with the two groups of deformation columns 205, so that the steel pipe can be installed without force. After installation, the steel pipe is processed, and the operation process is the same as that in Example 1. At this time, the push plate 202 starts to push the steel pipe for bending. At this time, there will be an arc offset at both ends of the steel pipe. Therefore, our solution is designed to make the arc setting of the arc groove 204a correspond to the arc of the second curved groove 202a and the first curved groove 205a on the push plate 202 and the deformation column 205. In this way, during the bending process of the steel pipe, the two ends will be offset. The offset distance can make the sliding column 204b-1 at the bottom of the rotating ball 204b-2 move in the arc groove 204a, and always keep the steel pipe in the through hole of the rotating ball 204b-2 without being out of fit. In this way, it can be ensured that the bending process will not cause the steel pipe as a whole not to be on the same horizontal plane. The phenomenon of bending and concavity.

[0039] Example 3

[0040] Reference Figure 1 to Figure 5 , which is the third embodiment of the present invention, further provides a method for manufacturing a mold, including keeping the pipe bend level with the first bend groove 205a and the second bend groove 202a during the manufacturing process, and keeping both ends of the steel pipe fixed during the pipe bending process.

[0041] Furthermore, the pressurized handle 203b ensures that the hydraulic cylinder 203a is pushed forward at a uniform speed during use.

[0042] Specifically, before starting to bend, make sure that the quality and size of the steel pipe meet the requirements, and check whether the various parts of the pipe bender are intact to ensure safe operation. If you need to bend accurately to a specific point such as the pipe end, bending point, etc., you can measure and mark the required distance X on the pipe fitting. ，Then adjust the hook and slider of the pipe bender according to this mark to ensure precise bending. In the process of pipe bending, it is necessary to ensure that the pipe can be bent by placing the deformation column 205. At this time, if the two sets of bending grooves are not on the same horizontal plane, the steel pipe may be twisted. In the process of pipe bending, the pressure handle 203 is used to apply pressure, and the hydraulic cylinder 203a needs to be pressurized at a uniform speed to avoid the deviation of the steel pipe due to excessive speed and uneven speed, and the arc of the steel pipe is not accurate enough.
