Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a hydraulic pipe bending processing device. Background Technology

[0002] Pipe bending is a process that bends pipes into a predetermined angle or arc shape using specific processing methods. It is widely used in fields such as building construction, chemical fluid transportation, automotive oil systems, and aerospace pipelines.

[0003] In industrial settings, pipe bending is a common operation. Traditional pipe bending methods often involve manual or simple mechanical processes. Bending pipes is labor-intensive and time-consuming, making it unsuitable for mass production. Furthermore, pipe bending can easily lead to problems such as pipe wall deformation, wrinkles, and elliptic cross-sections, affecting pipe performance and lifespan. Using specialized equipment for pipe bending is costly, and commercially available pipe bending machines are complex, expensive, and require advanced operating skills, making them unsuitable for widespread use by grassroots units.

[0004] Therefore, there is an urgent need for a hydraulic pipe bending processing device that is simple in structure, low in cost, easy to operate, and can guarantee the quality of pipe bending. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hydraulic pipe bending processing device, which aims to improve the problems of inconvenient operation of pipe bending devices and easy pipe deformation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic pipe bending processing device, comprising a base, a support plate fixedly installed on the top of the base, a connecting frame fixedly installed on the top of the support plate, a limit rod fixedly installed on the bottom of the connecting frame, a fixing block fixedly installed on the outer wall of the connecting frame, a slot opened at the bottom of the fixing block, a moving block slidably installed inside the fixing block, a telescopic spring installed on the top of the moving block, a support rod fixedly installed at the bottom of the moving block, and a pipe bending assembly provided on the top of the base.

[0007] The above technical solution involves inserting a telescopic spring and a movable block into the interior of the fixed block through a slot at the bottom of the fixed block. The top of the telescopic spring is fixedly connected to the top of the inner wall of the slot. Pulling the movable block can stretch the telescopic spring, causing the movable block to move up and down within the fixed block.

[0008] Preferably, the pipe bending assembly includes a connecting plate, a hydraulic jack is fixedly installed on the top of the connecting plate, and a bending block is fixedly installed on the top of the hydraulic jack.

[0009] Preferably, the bending block is triangular in shape and is located at the bottom of the limiting rod.

[0010] Preferably, the top of the telescopic spring is mounted on the top of the inner wall of the slot, and both the moving block and the telescopic spring are disposed inside the slot.

[0011] Preferably, there are two of each of the fixed block, movable block, telescopic spring, and limiting rod, and the two fixed blocks, movable blocks, telescopic springs, and limiting rods are symmetrically distributed outside the support plate.

[0012] Preferably, a connecting rod is fixedly installed on the outer wall of the support rod, and a lifting rod is fixedly installed on the top of the connecting rod.

[0013] Preferably, a docking sleeve is fixedly installed on the side of the connecting frame near the hydraulic jack, and the docking sleeve is sleeved on the outer surface of the lifting rod.

[0014] Preferably, the top of the connecting plate is provided with a threaded hole, and a fastening bolt is threaded into the inside of the threaded hole. The bottom of the fastening bolt penetrates the connecting plate and extends into the interior of the base.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, pressing down on the lifting rod causes the connecting rod and two support rods to move downwards together, which in turn causes the support rod to move the moving block downwards. The moving block pulls the telescopic spring, allowing the pipe to be placed on top of the support rod. Releasing the lifting rod causes the telescopic spring to retract, pulling the moving block and support rod upwards, clamping the pipe between the limiting rod and the support rod, thus achieving the effect of clamping and limiting the pipe to facilitate bending processing.

[0017] 2. In this utility model, the hydraulic jack drives the bending block to move upward, pressing against the bottom of the pipe and continuously moving upward to bend the pipe. The output shaft at the top of the hydraulic jack and the bending block lift upward to apply a uniform and controllable bending force to the pipe, thereby achieving a slow and uniform bending of the pipe and avoiding pipe deformation caused by instantaneous stress concentration, thus achieving the effect of bending the pipe.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1-4 An embodiment of this utility model provides a hydraulic pipe bending processing device, including a base 1, a support plate 11 fixedly installed on the top of the base 1, a connecting frame 2 fixedly installed on the top of the support plate 11, a limit rod 201 fixedly installed on the bottom of the connecting frame 2, a fixing block 202 fixedly installed on the outer wall of the connecting frame 2, a slot is opened at the bottom of the fixing block 202, a moving block 203 is slidably installed inside the fixing block 202, a telescopic spring 204 is installed on the top of the moving block 203, a support rod 205 is fixedly installed on the bottom of the moving block 203, and a pipe bending assembly is provided on the top of the base 1.

[0026] The top of the telescopic spring 204 is installed on the top of the inner wall of the slot, and both the moving block 203 and the telescopic spring 204 are located inside the slot.

[0027] There are two of each of the fixed block 202, movable block 203, telescopic spring 204 and limiting rod 201. The two fixed blocks 202, movable blocks 203, telescopic spring 204 and limiting rod 201 are symmetrically distributed outside the support plate 11.

[0028] Specifically, the bottom end of the telescopic spring 204 is fixedly connected to the top of the movable block 203. Then, the telescopic spring 204 and the movable block 203 are inserted into the interior of the fixed block 202 through the slot at the bottom of the fixed block 202. The top end of the telescopic spring 204 is fixedly connected to the top of the inner wall of the slot. Pulling the movable block 203 can stretch the telescopic spring 204, causing the movable block 203 to move up and down within the fixed block 202. The base 1, support plate 11, and connecting frame 2 are channel steel. The base 1 is placed horizontally on the ground, the support plate 11 is vertically installed on the top of the base 1, and the connecting frame 2 is horizontally installed on the top of the support plate 11. The limiting rod 201 is installed on the bottom of the connecting frame 2, and the outer surface of the limiting rod 201 is fixedly connected to the side of the support plate 11. Next, the limiting rod 201 is securely installed. When bending the pipe, the pipe is placed on top of the support rod 205, and the worker presses down on the pipe and the support rod 205, causing the support rod 205 to move the moving block 203 downward. The moving block 203 pulls the telescopic spring 204 to stretch, placing the pipe at the bottom of the limiting rod 201 and directly above the bending assembly. No more downward pressure is applied to the pipe and the support rod 205. The telescopic spring 204 pulls the moving block 203 and the support rod 205 upward, clamping the pipe at the top of the support rod 205 at the bottom of the limiting rod 201, clamping and limiting the pipe. The bending assembly applies upward force to bend the pipe, achieving the effect of limiting and fixing the pipe for easy bending processing.

[0029] It should be noted that when the bending component moves upward to bend the pipe, the pipe will bend from the point of force application, causing both ends of the pipe to move downward. This will apply downward pressure to the support rod 205, causing the support rod 205 to drive the moving block 203 and the telescopic spring 204 to move downward. The length specifications of the moving block 203 and the fixed block 202 will not cause the moving block 203 to detach from the fixed block 202. After the pipe is bent and removed, the telescopic spring 204 will pull the moving block 203 and the support rod 205 back to their original positions.

[0030] Considering the issue of how to bend the pipe, refer to Figure 1 and Figure 4 The pipe bending assembly includes a connecting plate 31, a hydraulic jack 32 is fixedly installed on the top of the connecting plate 31, and a bending block 33 is fixedly installed on the top of the hydraulic jack 32.

[0031] The bending block 33 is triangular in shape and is located at the bottom of the limiting rod 201.

[0032] The top of the connecting plate 31 has a threaded hole, and a fastening bolt 6 is threaded into the inside of the threaded hole. The bottom of the fastening bolt 6 passes through the connecting plate 31 and extends into the interior of the base 1.

[0033] Specifically, fastening bolts 6 are installed at the four corners of the top of the connecting plate 31, which can fix the connecting plate 31 to the top of the base 1. The top of the hydraulic jack 32 is fixedly connected to the connecting plate 31. The triangular bending block 33 is fixed to the top of the output end of the hydraulic jack 32. The triangular bending block 33 is composed of three plates, which can make the top of the bending block 33 at the top. After the pipeline is clamped and fixed by the limit rod 201 and the support rod 205, the operator presses the handle of the hydraulic jack 32 to move the bending block 33 upward. Positioned to hold the bottom of the pipe and continuously move upwards, bending the pipe. The output shaft of the hydraulic jack 32 and the bending block 33 lift upwards to apply a uniform and controllable bending force to the pipe, achieving a slow and uniform bending of the pipe. This avoids pipe deformation caused by instantaneous stress concentration, thus achieving the effect of bending the pipe. The hydraulic jack 32 applies force more evenly, effectively avoiding problems such as pipe deformation and wrinkling. It does not require electric drive, is suitable for non-electric or explosion-proof environments, has a simple structure, low failure rate, and almost zero maintenance cost.

[0034] It should be noted that the hydraulic jack 32 works by manually pressing the handle, using the principle of hydraulic transmission to convert the small force applied by the human hand into pressure in the hydraulic system, thereby generating a large lifting force on the piston to lift and bend the pipe.

[0035] Secondly, considering that the two support rods 205 need to be pressed down simultaneously to place the pipe between the two support rods 205 and the limiting rod 201, which is inconvenient for personnel operation, refer to... Figure 2 and Figure 4 A connecting rod 4 is fixedly installed on the outer wall of the support rod 205, and a lifting rod 41 is fixedly installed on the top of the connecting rod 4.

[0036] A docking sleeve 5 is fixedly installed on the side of the connecting frame 2 near the hydraulic jack 32, and the docking sleeve 5 is sleeved on the outer surface of the lifting rod 41.

[0037] Specifically, the connecting rod 4 is installed between the two support rods 205, and both ends of the connecting rod 4 are fixed to the outer walls of the two support rods 205 respectively. The lifting rod 41 is slidably inserted into the inside of the docking sleeve 5, and the bottom of the lifting rod 41 is fixedly installed to the top of the connecting rod 4. The top of the lifting rod 41 extends to the top of the connecting frame 2. When the personnel need to place the pipe under the limiting rod 201 for clamping, they press down on the lifting rod 41 to drive the connecting rod 4 and the two support rods 205 to move downward together, which makes it easier for the personnel to place the pipe between the support rod 205 and the limiting rod 201 for clamping and fixing.

[0038] Working principle: When bending the pipe, the pipe is placed on top of the support rod 205. Pressing down the lifting rod 41 moves the connecting rod 4 and the two support rods 205 downwards together, causing the support rods 205 to move the moving block 203 downwards. The moving block 203 pulls the telescopic spring 204 to stretch, allowing the pipe to be placed on top of the support rod 205. The pipe is adjusted to be directly above the bending block 33, and the bending point is aligned with the force application point of the bending block 33. Releasing the lifting rod 41 causes the telescopic spring 204 to retract, pulling the moving block 203 and the support rod 205 upwards, clamping the pipe between the limiting rod 201 and the support rod 205, achieving the effect of clamping and limiting the pipe to facilitate bending processing.

[0039] After the pipe is clamped and fixed by the limit rod 201 and the support rod 205, the operator presses the handle of the hydraulic jack 32 to move the bending block 33 upward. The bending block 33 is pushed against the bottom of the pipe and continuously moved upward to bend the pipe. The output shaft of the hydraulic jack 32 and the bending block 33 lift the pipe upward to apply a uniform and controllable bending force to achieve a slow and uniform bending of the pipe.

[0040] 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.
