Description

Technical Field

[0001] This utility model provides a ruler, and particularly relates to an auxiliary ruler for a pipe bender. Background Technology

[0002] The auxiliary ruler of the pipe bender is a key auxiliary component used in conjunction with the pipe bender during pipe bending operations. It is mainly used to provide operators with angle references during the pipe bending process, helping to control the bending angle of the pipe and ensuring that the bent pipe meets the preset size and angle requirements. It is widely used in fields such as pipeline installation, machinery manufacturing, and furniture processing that require bending of metal or plastic pipes. Its performance directly affects the accuracy and efficiency of pipe bending operations.

[0003] Existing auxiliary rulers for pipe benders typically consist of a ruler body connected to the bender base. The ruler usually has angle markings, and some products include simple limiting devices to restrict the bending angle. However, these existing structures have significant shortcomings: First, the connection between the ruler and the bender is mostly a single fixed method, lacking symmetrical support on both sides, making the ruler prone to wobbling and affecting the accuracy of angle reading. Second, the limiting devices are mostly fixed by bolts, requiring complete loosening of the bolts for adjustment, which is cumbersome and has poor locking stability. They are prone to displacement when the pipe is under bending force, making it difficult to guarantee angle control accuracy. Third, existing bases are mostly solid flat plates or simple frame structures without dedicated buffer space, making it easy for the pipe to interfere with the base during bending, leading to localized deformation of the pipe or deviations in the bending angle. Fourth, the correspondence between the scale markings and the bending angle is not intuitive enough, and there is a lack of positioning structures that match commonly used angles, requiring operators to repeatedly check the scale, increasing the difficulty of operation and the error rate.

[0028] 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.

[0029] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figures 1-3 As shown, this embodiment provides an auxiliary ruler for a pipe bender, including a base 1. The base 1 is a long strip structure, specifically a cuboid frame, which is lightweight and has a certain strength. One end of the base 1 is connected to a fixing seat 3 via a first frame 2. The fixing seat 3 includes a fixing seat 3 body and a pipe fixing structure such as a clamp or clamp disposed on the fixing seat 3 body for fixing one end of the pipe to be bent. The fixing seat 3 body is fixedly connected to the base 1 via the first frame 2, ensuring a stable connection.

[0032] The other end of the base 1 is connected to a movable seat 5 via a second frame 4. The movable seat 5 includes a movable seat 5 body and a tube clamping structure disposed on the movable seat 5 body for clamping the section of the tube to be bent. The movable seat 5 body is rotatably connected to the base 1 via the second frame 4, so that the movable seat 5 can rotate relative to the base 1 to perform the tube bending operation.

[0033] Auxiliary rulers 6 are fixedly connected to both sides of the base 1. The auxiliary rulers 6 are long strips that extend along the length of the base 1. The two ends of the auxiliary rulers 6 are fixedly connected to the first frame 2 and the second frame 4, respectively, so that the auxiliary rulers 6 are set parallel to the base 1, thereby providing symmetrical and stable support for the auxiliary rulers 6 and preventing them from shaking.

[0034] The auxiliary ruler 6 is provided with scale markings 7, which are distributed along the length of the auxiliary ruler 6, and the scale values ​​of the scale markings 7 correspond to the rotation angle of the movable seat 5, making it easy for operators to intuitively read the bending angle. The auxiliary ruler 6 is also provided with several slots 8, which correspond to several commonly used bending angles such as 30°, 45°, 90°, etc. The slots 8 are grooves spaced apart along the length of the auxiliary ruler 6.

[0035] The auxiliary scale 6 is also provided with a limit stop rod 9. The end of the limit stop rod 9 can be inserted into the groove. A locking nut is sleeved on the limit stop rod 9. The locking nut can abut against the surface of the auxiliary scale 6 to lock the position, so that the limit stop rod 9 can cooperate with the slot 8 and be locked on the auxiliary scale 6 by the locking nut, thereby limiting the range of motion angle of the movable seat 5.

[0036] The base 1 is provided with a buffer space groove 10, which is a long groove formed on the upper surface of the base 1. The length direction of the buffer space groove 10 is consistent with the length direction of the base 1, which is used to adapt to the space requirements when the tube is bent and to avoid interference between the tube and the base 1.

[0037] The working process of this embodiment:

[0038] In use, first fix one end of the pipe to be bent using the pipe fixing structure of the fixed seat 3, and clamp the section to be bent using the pipe clamping structure of the movable seat 5; according to the required bending angle, insert the end of the limit stop rod 9 into the corresponding angle slot 8 on the auxiliary scale 6, and tighten the locking nut to lock the limit stop rod 9 stably; then rotate the movable seat 5 to drive the pipe to bend, and when the movable seat 5 rotates to contact the limit stop rod 9, the preset bending angle is reached; during this process, the buffer space groove 10 on the base 1 provides sufficient space for the pipe to bend, and the scale markings 7 on the auxiliary scale 6 can help the operator observe the angle change in real time to ensure the bending accuracy.

[0039] In practical use, this device needs to be used in conjunction with existing pipe benders, including the handle operation component of a manual pipe bender or the drive motor component of an electric pipe bender. The pipe fixing structure and pipe clamping structure need to be matched with existing standard pipe clamps and bolt fasteners. Rubber anti-slip pads can be added to the contact surface of the pipe to enhance clamping stability. The base, first frame and second frame are usually made of Q235 low carbon steel by welding or bolting. The auxiliary scale is made of 6061 aluminum alloy with scale markings and slots machined by CNC milling. The limit stop rod is made of 45 steel by turning. The locking nut is made of 304 stainless steel. If the wear resistance of the buffer space groove needs to be improved, polytetrafluoroethylene board can be laid in the groove. At the same time, before operation, the measurement of the part of the pipe to be bent should be predicted with the help of existing tape measures or angle gauges, and the initial position should be calibrated with the scale markings of this device. When placing the pipe, existing V-shaped positioning blocks can be used to help align the clamping center of the fixed seat and the movable seat. After the pipe bending operation is completed, existing angle gauges can be used to check the bending angle to ensure that it meets the process requirements.

[0040] Specifically, during installation, the base can be fixed to the workbench using existing expansion bolts to ensure overall stability. The connection between the pipe bender body and the movable seat can be detached using existing flanges and hex bolts. The pipe clamps of the pipe fixing structure can be adjusted for tightness according to the pipe diameter using existing adjusting bolts. Existing deep groove ball bearings can be used at the rotating shaft of the movable seat to reduce rotational friction, and lithium-based grease can be applied periodically for maintenance. During operation, if it is a manual pipe bender, the operator needs to hold the existing handle assembly and slowly apply force around the rotating shaft; if it is an electric pipe bender, it can be started via the existing control panel. Drive the motor and adjust the speed to the appropriate gear. When the movable seat approaches the limit stop bar, the operating speed should be slowed down to avoid excessive impact force that could cause structural deformation. When the tube is pre-positioned, the existing laser positioning instrument can be used to project the baseline to assist in aligning with the initial zero point of the scale mark. During the operation, the operator must wear existing non-slip gloves to prevent the tube from sliding or causing hand abrasions. After the tube is bent, if burrs appear at the end of the tube, they can be polished using existing assorted files. For longer tubes, existing tube support frames can be used to provide auxiliary support in the non-bending section to prevent the tube from deflecting due to its own weight and affecting the bending accuracy.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
