Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-pressure pipe processing technology, and in particular to a multi-bend corrosion-resistant low-pressure pipe production tooling. Background Technology
[0002] Multi-bend corrosion-resistant low-pressure pipes are widely used in many industrial sectors, such as chemical, petroleum, natural gas, and HVAC. They are responsible for transporting various media with certain corrosive properties. In the processing of low-pressure pipes, multi-bend bending is a key process, which is completed by pipe bending production fixtures. Common pipe bending production fixtures mainly consist of a drive motor, a bending component, and a cylinder. In actual operation, the first step is to accurately place the low-pressure pipe to be processed into the bending station of the bending component. Then, the cylinder is started, and its drive shaft extends and presses against the low-pressure pipe, which plays the role of fixing and applying initial pressure. Finally, the drive motor is started, which drives the bending component to start rotating. During this process, the low-pressure pipe undergoes bending deformation under the combined action of pressure and rotation, thereby achieving the required multi-bend processing.
[0003] In the process of processing low-pressure pipe fittings with multiple bends, the pipe fittings have various diameter specifications, and it is necessary to frequently change the bending components that are suitable for different pipe diameter bending stations. However, the existing bending components are mostly fixed to the output shaft of the drive motor with screws and nuts. When disassembling, the screws and nuts need to be unscrewed one by one, and when installing, the screw holes need to be aligned and tightened repeatedly. The steps are complicated and the operation is time-consuming, resulting in low efficiency in changing bending components. Utility Model Content
[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: In the process of processing low-pressure pipe fittings with multiple bends, the pipe fittings have various diameter specifications, and it is necessary to frequently change the bending components that are suitable for different pipe diameter bending stations. However, the existing bending components are mostly fixed to the output shaft of the drive motor with screws and nuts. When disassembling, the screws and nuts need to be unscrewed one by one, and when installing, the screw holes need to be aligned and tightened repeatedly. The steps are complicated and the operation is time-consuming, resulting in low efficiency of bending component replacement. Therefore, a multi-bend corrosion-resistant low-pressure pipe production tooling is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-bend corrosion-resistant low-pressure pipe production fixture includes a drive motor and a bending component.

The rectangular block has insertion holes on both its left and right side walls for the ends of the two inserts to pass through. The depth of the rectangular groove is the same as the thickness of the mounting block. The surface of the rectangular block is provided with a pressing component for controlling the two inserts to move closer to each other.
[0008] Preferably, the pressing assembly includes two L-shaped sliding plates and two abutment rods respectively fixedly installed on the surfaces of the two sliding plates.

[0009] Preferably, the telescopic component includes two telescopic springs, the two ends of which are fixedly connected to one end of the slide plate and the wall of the slide opening, respectively.
[0010] Preferably, a contact block is fixedly installed at the end of the abutment away from the slide plate, and the contact block is made of rubber.
[0011] Preferably, a rotating rod is horizontally rotatably mounted on the surface of the rectangular block, a fixed rod is fixedly sleeved on the rotating rod, and a rotating opening is provided at both ends of the fixed rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0023] Reference Figures 1-5 A multi-bend corrosion-resistant low-pressure pipe production fixture includes a drive motor 1 and a bending component 2. A rectangular block 3 is fixedly installed at the top of the output shaft of the drive motor 1. A rectangular mounting block 4 is fixedly installed at the bottom of the bending component 2 via a vertical rod. A rectangular groove 5 is formed on the upper surface of the rectangular block 3 for the mounting block 4 to be inserted. The mounting block 4 is slidably inserted into the rectangular groove 5. The shape of the mounting block 4 is adapted to the rectangular groove 5, and the size of the mounting block 4 forms a clearance fit or interference fit with the inner wall of the rectangular groove 5. After the mounting block 4 is inserted into the rectangular groove 5, the side wall of the rectangular groove 5 forms a limiting constraint on the lateral movement of the mounting block 4, so that the mounting block 4 cannot move laterally.
[0024] Mounting block 4 has mounting grooves 6 on both its left and right side walls. Spring rods 7 are symmetrically and horizontally fixedly installed in the mounting grooves 6. Insert blocks 8 with a right-angled trapezoidal longitudinal section are fixedly installed at the ends of the two spring rods 7. The inclined surfaces of the insert blocks 8 face downwards and the insert blocks 8 are slidably disposed in the mounting grooves 6. Rectangular block 3 has insertion holes 9 on both its left and right side walls for the ends of the two insert blocks 8 to pass through. The depth of the rectangular groove 5 is the same as the thickness of the mounting block 4. The surface of rectangular block 3 is provided with a pressing component for controlling the two insert blocks 8 to move closer to each other. The pressing component includes two L-shaped sliding plates 10 and two abutment rods 11 fixedly installed on the surfaces of the two sliding plates 10. The surface of rectangular block 3 has symmetrical sliding openings. The two sliding plates 10 are horizontally slidably installed in the two sliding openings. The ends of the two abutment rods 11 correspond to the positions of the two insertion holes 9. The sliding plates 10 are connected to the sliding opening wall through a telescopic component. The telescopic component includes two telescopic springs 12. The two ends of the telescopic springs 12 are fixedly connected to one end of the sliding plate 10 and the sliding opening wall, respectively.
[0025] When it is necessary to install the bent component 2, first align the mounting block 4 with the rectangular groove 5, and then position the two inserts 8 above the two sockets 9 respectively. Then, control the mounting block 4 to move down into the rectangular groove 5. The inclined surfaces of the two inserts 8 will slide into contact with the top of the rectangular block 3. Under the pressure of the inclined surfaces, the two inserts 8 will move closer to each other, and the multiple spring rods 7 will retract together until the mounting block 4 is completely moved into the rectangular groove 5. After the lower surface of the mounting block 4 abuts against the bottom of the rectangular groove 5, the two inserts 8 will correspond to the positions of the two sockets 9 respectively. The pressure force exerted on the inserts 8 by the groove wall of the rectangular groove 5 will disappear, and the inserts 8 will quickly move and reset under the elastic potential energy of the spring rods 7. The two inserts 8 will be inserted into the two sockets 9 respectively, and the straight edge of the top of the insert 8 will abut against the inner top wall of the socket 9, thereby forming a locking engagement.
[0026] In the initial state, all the telescopic springs 12 are in their natural state, and the ends of the two abutment rods 11 are not located in the sockets 9. When it is necessary to disassemble the bending component 2, the two sliding plates 10 can be controlled to move closer to each other, so that the two abutment rods 11 also move closer to each other. The telescopic springs 12 will then contract, and the ends of the two abutment rods 11 that are close to each other will enter the two sockets 9 respectively, pushing the two plug blocks 8 closer to each other until the ends of the two plug blocks 8 are moved out of the two sockets 9 respectively. Then the locking between the mounting block 4 and the rectangular block 3 can be released, and the bending component 2 can be removed and replaced.
[0027] A contact block 13 is fixedly installed at the end of the stop bar 11 away from the slide plate 10. The contact block 13 is made of rubber.
[0028] The rubber contact block 13 can increase the friction between the contact surfaces of the push rod 11 and the insert block 8, while reducing the damage caused when the push rod 11 and the insert block 8 come into contact.
[0029] A rotating rod 14 is horizontally mounted on the surface of the rectangular block 3. A fixed rod 15 is fixedly sleeved on the rotating rod 14. Both ends of the fixed rod 15 are provided with rotating openings. A rotating shaft 16 is rotatably mounted on the surface of the slide plate 10 and the inner wall of the rotating opening. A hinge rod 17 is rotatably sleeved on every two rotating shafts 16.
[0030] When the telescopic spring 12 is in its natural state, the fixed rod 15, the slide plate 10, and the hinge rod 17 are all in a horizontal state. When it is necessary to disassemble the bending component 2, the fixed rod 15 can be rotated by rotating the rotating rod 14, causing the two hinge rods 17 to tilt. At this time, the two slide plates 10 will move closer to each other, and the two abutment rods 11 will also move closer to each other. The effect of controlling the two slide plates 10 to move closer to each other can be achieved simply by controlling the rotating rod 14 to rotate.
[0031] A handle is fixedly installed at one end of the rotating rod 14. The surface of the handle is provided with anti-slip texture. The handle makes it easy to control the rotation of the rotating rod 14, and the anti-slip texture can increase the friction between the palm and the contact surface of the rotating rod 14.
[0032] In this utility model, the bending component 2 can be quickly disassembled and assembled through the cooperation between the insert block 8, spring rod 7, rectangular block 3, mounting block 4 and pressing component. It is convenient and quick, and does not require the use of professional tools to rotate the screws and nuts, thus improving the work efficiency of replacing the bending component 2.
[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
