Description

Technical Field

[0001] The invention relates to the field of pipeline processing, and in particular to a manufacturing device and a manufacturing method for a flexible pipe. Background Art

[0002] A flexible pipe refers to a pipe system with a certain degree of flexibility, which can deform to a certain extent when subjected to external forces and is not easily broken. The flexible PE pipe itself can withstand the load generated by underground movement and bear the load together with the surrounding soil. Therefore, even if its compressive strength and stiffness are not as good as metal pipes, it can meet the requirements of mechanical properties.

[0003] The existing PE pipes need to be cut during the manufacturing process. After cutting to a uniform length, it is convenient for the transportation and subsequent installation of the pipe body. The existing PE pipe cutting and processing equipment still has the following problems during use: the PE pipe will produce debris during the processing and cutting process. The diameter of the debris particles is small. The debris splashes into the air and is accidentally inhaled by the staff, which may have an impact on their health. At the same time, the splashed debris is not convenient to be uniformly collected and processed, causing hygiene problems in the processing area.

[0004] Therefore, it is necessary to invent a manufacturing device and a manufacturing method of a flexible pipe to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a manufacturing device and a manufacturing method for a flexible pipe, so as to solve the problem that the PE pipe proposed in the above background technology will generate debris during the processing and cutting process. The diameter of the debris particles is small, and the debris splashes into the air and is accidentally inhaled by the staff, which may have an impact on their health. At the same time, the splashed debris is not convenient to be uniformly collected and processed, causing hygiene problems in the processing area.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a manufacturing device for a flexible pipe, comprising a processing seat, wherein four corners of the top wall of the processing seat are fixedly connected with upright poles, and a top plate is fixedly installed on the top of the upright pole, a placement groove is reserved inside the processing seat, and a PE pipe body is placed inside the placement groove, and the placement groove is connected to the knife groove, a cylinder is embedded inside the top plate, and a pressure block is fixedly connected to the output end of the cylinder, and a splash shield is movably installed below the pressure block, a cavity is opened inside the pressure block, and a cutting knife group is fixedly installed on the inner wall of the cavity, and further comprising:

[0007] Abutment assembly, wherein a vertical groove 1 is provided inside the splash shield, and a long plate is elastically connected inside the vertical groove 1 through a spring, and the upper end of the long plate moves in the cavity;

[0008] The disassembly and assembly component is provided with a notch at the upper end of the long plate, and a rotating block is rotatably connected to the inside of the notch through a rotating shaft, and the rotating block moves inside a second vertical groove connected to the cavity.

[0009] Preferably, the lower ends of the pressing block and the splash shield are respectively provided with arc groove 1 and arc groove 2, and the arc inner walls of the arc groove 1 and the arc groove 2 are both fitted with the outer wall of the PE pipe body, so that the pressing block and the splash shield can completely fit the PE pipe body, so that a closed area can be formed between the pressing block and the splash shield and the processing seat, thereby preventing the debris generated during the cutting process from splashing and affecting the subsequent processing operations;

[0010] There is a gap between the lower end of the pressing block and the upper end of the splash cover, and the distance of the gap is smaller than the gap between the blade in the cutting knife group and the PE pipe body. In this way, during the descending process of the pressing block, the inner wall of the internal cavity of the pressing block first contacts the outer wall of the splash cover to form a closed area, and then the blade contacts the PE pipe body to perform the cutting operation, thereby ensuring that the debris generated by the cutting is sealed in the closed area formed by the pressing block, the splash cover and the processing seat.

[0011] Preferably, the four corners of the pressing block are movably sleeved on the outer rings of the four vertical poles and are connected to the vertical poles in an up-and-down sliding manner, thereby ensuring the stability of the pressing block when it moves up and down.

[0012] Preferably, the splash guard is through-through from top to bottom, and the outer wall of the splash guard is in contact with the inner wall of the cavity and is slidably connected up and down, and the height of the splash guard is the same as the height of the cavity, so that the splash guard can be completely received in the cavity, ensuring that the blade has enough descending space to cut the PE pipe body.

[0013] Preferably, the two side walls of the lower end of the long board are fixedly connected to the limiting block, and the outer wall of the limiting block is in contact with the inner wall of the limiting groove and is slidably connected up and down, the limiting groove is connected to the vertical groove, and the upper and lower end walls of the limiting groove are both closed ends.

[0014] Preferably, the upper and lower ends of the spring are fixedly connected to the lower end of the long plate and the bottom wall of the vertical groove 1 respectively.

[0015] Preferably, the two ends of the rotating shaft are rotatably connected with the inner wall of the notch through bearings, and the outer wall of the rotating shaft is fixedly covered with a rotating block, and the outer ring of the rotating shaft is movably covered with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected with the outer wall of the rotating block and the inner wall of the notch. In this way, when the splash guard needs to be removed and replaced, the long plate is continuously pulled down so that the rotating block rotatably connected with the long plate presses against the notch at the lower end of the vertical groove 2 and flips upward, and the rotating block gradually leaves the interior of the vertical groove 2.

[0016] Preferably, the lower end wall of the rotating block is in contact with the inner wall of the notch and is movably connected.

[0017] The present invention also provides a method for manufacturing a flexible pipe, using the above-mentioned manufacturing device for a flexible pipe, and the specific operating steps are as follows:

[0018] Step 1: Place the PE pipe body. Push the splash guard upwards and place the PE pipe body to be cut inside the placement groove. Then the splash guard's own gravity will press against the outer wall of the PE pipe body and fit it.

[0019] Step 2: Formation of a closed space: Start the cylinder to drive the pressing block down, and a closed area is formed between the cavity reserved inside the pressing block and the splash shield. The blade inside the subsequent cutting knife group descends to contact the PE pipe body and cut it;

[0020] Step 3: It is convenient to collect the debris in a unified manner. After the blade continues to descend and cuts the PE pipe body, the PE pipe body can be taken out.

[0021] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0022] 1. The present invention places the PE pipe body to be cut inside the placement groove by pushing the splash guard upward, and then the splash guard's own gravity presses against the outer wall of the PE pipe body and fits with it. At this time, a closed space is formed, and the blade inside the subsequent cutting knife group descends to contact and cut the PE pipe body. In this way, the debris generated during the cutting process is concentrated in the closed area, which is convenient for the staff to collect;

[0023] 2. Pull down the long board so that the rotating block connected to the long board moves downward synchronously and presses against the notch at the lower end of the vertical slot 2 to realize upward flipping. In this way, the upper end of the long board gradually leaves the cavity. At this time, the splash guard is removed and replaced. When a new splash guard is installed later, flip the rotating block connected to the inside of the long board upward, lift the splash guard so that the outer wall of the splash guard fits with the inner wall of the cavity, and release the rotating block. Under the action of the torsion spring on the outer ring of the rotating shaft, the rotating block realizes reset rotation and matches the vertical slot 2 reserved inside the cavity. At this time, the installation of the new splash guard and the pressing block is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The present invention provides Figure 1-6 A manufacturing device for a flexible pipe shown in the figure comprises a processing seat 1, a vertical pole 2 is fixedly connected at the four corners of the top wall of the processing seat 1, and a top plate 3 is fixedly installed on the top of the vertical pole 2, a placement groove 4 is reserved inside the processing seat 1, and a PE pipe body 5 is placed inside the placement groove 4, and the placement groove 4 is connected to the knife groove 15, a cylinder 6 is embedded and installed inside the top plate 3, and a pressure block 7 is fixedly connected to the output end of the cylinder 6, and a splash shield 9 is movably installed below the pressure block 7, a cavity 11 is opened inside the pressure block 7, and a cutting knife group 12 is fixedly installed on the inner wall of the cavity 11, and also includes:

[0035] Abutting assembly 13, a vertical groove 131 is provided inside the splash shield 9, and a long plate 132 is elastically connected inside the vertical groove 131 through a spring 135, and the upper end of the long plate 132 moves in the cavity 11;

[0036] The disassembly assembly 14 has a notch 141 reserved at the upper end of the long plate 132 , and the inside of the notch 141 is rotatably connected to a rotating block 143 via a rotating shaft 142 , and the rotating block 143 moves inside a second vertical slot 144 connected to the cavity 11 .

[0037] The lower ends of the pressing block 7 and the splash shield 9 are respectively provided with an arc groove 1 8 and an arc groove 2 10, and the arc inner walls of the arc groove 1 8 and the arc groove 2 10 are both fitted with the outer wall of the PE pipe body 5, so that the pressing block 7 and the splash shield 9 can be completely fitted with the PE pipe body 5, so that a closed area can be formed between the pressing block 7 and the splash shield 9 and the processing seat 1, so as to avoid the splashing of debris generated during the cutting process to affect the subsequent processing operations;

[0038] There is a gap between the lower end of the pressing block 7 and the upper end of the splash cover 9, and the distance of the gap is smaller than the gap between the blade in the cutting knife group 12 and the PE pipe body 5. In this way, during the descending process of the pressing block 7, the inner wall of the internal cavity 11 of the pressing block 7 first contacts the outer wall of the splash cover 9 to form a closed area, and then the blade contacts the PE pipe body 5 to perform the cutting operation, thereby ensuring that the debris generated by the cutting is sealed in the closed area formed by the pressing block 7, the splash cover 9 and the processing seat 1.

[0039] The four corners of the pressing block 7 are movably mounted on the outer circles of the four vertical poles 2 and are connected with the vertical poles 2 in an up-and-down sliding manner, thereby ensuring the stability of the pressing block 7 when it moves up and down.

[0040] The splash guard 9 is through-through from top to bottom, and the outer wall of the splash guard 9 is in contact with the inner wall of the cavity 11 and is slidably connected up and down, and the height of the splash guard 9 is the same as the height of the cavity 11, so that the splash guard 9 can be completely received in the cavity 11, ensuring that the blade has enough descending space to cut the PE pipe body 5.

[0041] The two side walls of the lower end of the long plate 132 are fixedly connected with the limiting block 133, and the outer wall of the limiting block 133 is in contact with the inner wall of the limiting groove 134 and is slidably connected up and down. The limiting groove 134 is connected to the vertical groove 131, and the upper and lower end walls of the limiting groove 134 are both closed ends.

[0042] The upper and lower ends of the spring 135 are fixedly connected to the lower end of the long plate 132 and the bottom wall of the vertical groove 131 respectively.

[0043] The two ends of the rotating shaft 142 are rotatably connected to the inner wall of the notch 141 through bearings, and the outer wall of the rotating shaft 142 is fixedly sleeved with a rotating block 143, and the outer ring of the rotating shaft 142 is movably sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the outer wall of the rotating block 143 and the inner wall of the notch 141. In this way, when the splash guard 9 needs to be removed and replaced, the long plate 132 is continuously pulled down so that the rotating block 143 rotatably connected to the long plate 132 presses against the notch at the lower end of the vertical groove 144 and flips upward, and the rotating block 143 gradually leaves the interior of the vertical groove 144.

[0044] The lower end wall of the rotating block 143 is in contact with the inner wall of the notch 141 and is movably connected thereto.

[0045] The present invention also provides a method for manufacturing a flexible pipe, using the above-mentioned manufacturing device for a flexible pipe, and the specific operating steps are as follows:

[0046] Step 1: Place the PE tube body 5. Move the splash guard 9 upwards to place the PE tube body 5 to be cut inside the placement groove 4. Then the splash guard 9 is pressed against the outer wall of the PE tube body 5 by its own gravity and fits with it.

[0047] Step 2: Formation of a closed space: Start the cylinder 6 to drive the pressing block 7 to descend, and a closed area is formed between the cavity 11 reserved inside the pressing block 7 and the splash shield 9. The blade inside the subsequent cutting knife group 12 descends to contact the PE pipe body 5 and cut it;

[0048] Step 3: It is convenient to collect the debris in a unified manner. After the blade continues to descend and cuts the PE tube body 5, the PE tube body 5 can be taken out.

[0049] Working principle: When using a manufacturing device and manufacturing method for a flexible pipe, first push the splash shield 9 upward to drive the splash shield 9 to move upward, and then place the PE pipe body 5 to be cut inside the placement groove 4, put down the splash shield 9, and under the action of the splash shield 9's own gravity, the inner wall of the arc groove 10 reserved inside the splash shield 9 fits with the outer wall of the PE pipe body 5 to be processed, and then start the cylinder 6 to drive the pressing block 7 fixedly connected to the lower end of the cylinder 6 to descend. During the descent of the pressing block 7, the lower end of the pressing block 7 gradually covers the outside of the splash shield 9, and the inner wall of the cavity 11 reserved inside the pressing block 7 contacts the outer wall of the splash shield 9 to form a closed area with the processing seat 1. Then, during the descent of the pressing block 7, the cutting knife group 12 arranged on the inner wall of the cavity 11 inside the pressing block 7 is driven to descend synchronously. During the descent of the blade inside the cutting knife group 12, the blade contacts and cuts the PE pipe body 5 placed inside the placement groove 4. At this time, due to the descent of the pressing block 7, the inner wall of the cavity 11 contacts the outer wall of the splash shield 9 to form a closed area. The debris generated during the cutting process between the blade inside the cutting knife group 12 and the PE pipe body 5 is only splashed inside the closed area, so that the activity range of the debris is small, and the subsequent unified collection of the debris is more convenient. After the blade continues to descend and the PE pipe body 5 is cut, the PE pipe body 5 can be taken out;

[0050] When the splash shield 9 needs to be replaced later, the long plate 132 is pulled down, and the lower end of the long plate 132 moves inside the vertical groove 131. At this time, the rotating block 143, which is rotatably connected to the upper end of the long plate 132 through the rotating shaft 142, moves downward synchronously to resist the lower end notch of the vertical groove 2 144. Since the rotating block 143 is rotatably connected to the long plate 132 through the torsion spring, the long plate 132 is pulled down at this time to make the rotating block 143 flip upward, so that the upper end of the long plate 132 gradually leaves the cavity 11, and the splash shield 9 is removed and replaced. When installing a new splash shield 9 later, the long plate 132 that is movably connected inside the new splash shield 9 is pressed down synchronously, and then the rotating block 143 that is rotatably connected inside the long plate 132 is flipped upward, the splash shield 9 is lifted so that the outer wall of the splash shield 9 fits with the inner wall of the cavity 11, and the rotating block 143 is released. At this time, under the force generated by the reset movement of the torsion spring on the outer ring of the rotating shaft 142, the rotating block 143 realizes the reset rotation and matches the vertical groove 144 reserved inside the cavity 11. At this time, the new splash shield 9 and the pressing block 7 are installed.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
