Description

Technical Field

[0001] The present application relates to the technical field of pipe processing, and in particular to a sleeve removal device and a core mold. Background Art

[0002] At present, most of the demoulding methods on the market are manual demoulding, which often causes scratches and damage to the inner and outer walls of the pipe, which will seriously affect the quality of the product. At the same time, most of the current demoulding equipment is for demoulding pipes with circular cross-sections. When demoulding circular pipes, the angle of rotation along the radial direction of the pipe is not high, but this demoulding equipment cannot be applied to pipes with elliptical cross-sections or other irregular pipes; in addition, some equipment uses a core-pulling mechanism to demould pipes, but these equipment are often only suitable for small products, and are also not suitable for demoulding large-sized elliptical pipes. Summary of the invention

[0003] The present application at least provides a sleeve removal device and a core mold, which can improve the efficiency of pipe demoulding and can be suitable for demoulding pipes of different shapes.

[0004] The present application provides a sleeve removal device, comprising: a frame; a core mold clamping device, which is arranged at one end of the frame, and the core mold clamping device comprises an anti-rotation mechanism, which is used to abut against an anti-rotation rod at one end of the core mold so as to fix the relative position between the core mold and the core mold clamping device; a sleeve removal device, which is arranged on the frame and is used to demold the pipe sleeved on the core mold and / or sleeve the pipe onto the core mold.

[0005] Among them, the number of anti-rotation rods is one, and the anti-rotation mechanism includes at least two first baffles, which are respectively arranged on both sides of the anti-rotation rod along the target direction, and the target direction is perpendicular to the initial extension direction of the anti-rotation rod, so that when the stripping device is demolding the tube sleeved on the core mold and / or sleeves the tube onto the core mold, the angle between the anti-rotation rod and the initial extension direction is less than or equal to a preset angle.

[0006] Among them, the anti-rotation rod at least includes a first anti-rotation rod and a second anti-rotation rod, and the anti-rotation mechanism includes at least a second baffle and a third baffle, the second baffle is arranged on one side of the first anti-rotation rod, and the third baffle is arranged on one side of the second anti-rotation rod; wherein the first anti-rotation rod, the second baffle, the third baffle and the second anti-rotation rod are arranged clockwise or counterclockwise, so that when the stripping device is demolding the tube sleeved on the core mold and / or sleeves the tube onto the core mold, the angle between the first anti-rotation rod and the second anti-rotation rod and their respective initial extension directions is less than or equal to a preset angle.

[0007] Among them, the anti-rotation mechanism also includes a guide plate, which is fixed on the frame and connected to each baffle. The core mold clamping device also includes a first driving mechanism, which is used to drive the core mold to move toward the corresponding baffle or away from the corresponding baffle so as to abut against the corresponding anti-rotation rod or move away from the corresponding baffle.

[0008] Among them, the first driving mechanism also includes an upper hydraulic cylinder and an upper clamping seat, the upper clamping seat is slidably connected to the guide plate, wherein the upper clamping seat is used to place the core mold, and the piston rod of the upper hydraulic cylinder is fixedly connected to the upper clamping seat to drive the upper clamping seat to slide on the guide plate, so as to drive the core mold to move in the direction toward the corresponding baffle plate or in the direction away from the corresponding baffle plate.

[0009] Among them, the stripping device includes a retaining ring, a clamping mechanism and a second driving mechanism. The retaining ring is annular and is used to be sleeved on the outer periphery of the core mold and abut the end of the tube. The clamping mechanism is used to clamp the retaining ring. The second driving mechanism is used to drive the clamping mechanism to move along the axial direction of the core mold, thereby driving the retaining ring and the tube abutting against the retaining ring to move along the axial direction of the core mold, so as to demold the tube sleeved on the core mold and / or sleeve the tube onto the core mold.

[0010] Among them, the clamping mechanism includes two claws and a clamping seat. The two claws are arranged on the clamping seat along the radial direction of the core mold. The clamping seat is slidably connected to the frame. The second driving mechanism is arranged at the bottom of the clamping seat. The second driving mechanism is connected to the claws. The second driving mechanism is used to drive the two claws to move on the clamping seat along the radial direction of the core mold, so that the claws clamp or release the retaining ring.

[0027] Please also see Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of the demoulding device of the present application, Figure 2 yes Figure 1 The demoulding device 100 comprises a frame 110 , a core mold clamping device 120 and a sleeve stripping device 130 .

[0028] The core mold clamping device 120 is disposed at one end of the frame 110. The core mold clamping device 120 includes an anti-rotation mechanism 121, which is used to abut against an anti-rotation rod 201 at one end of the core mold 200 so that the relative position between the core mold 200 and the core mold clamping device 120 is fixed.

[0029] The stripping device 130 is disposed on the frame 110 and is used to strip the pipe sleeved on the core mold 200 and / or sleeve the pipe onto the core mold 200 .

[0030] The demoulding device 100 described herein is a device that can demould or mold irregular tubes, such as elliptical tubes. At the same time, irregular tubes are prone to tilt or rotate during demoulding or mold molding, which can lead to failure in demoulding or mold molding. In order to reduce the occurrence of this phenomenon, an anti-rotation mechanism 121 is added in this application.

[0031] In some embodiments, the number of the anti-rotation rod 201 of the core mold 200 is one, and the anti-rotation mechanism 121 of the core mold clamping device 120 includes at least two first baffles 1212, and the two first baffles 1212 are respectively arranged on both sides of the anti-rotation rod 201 along the target direction, and the target direction is perpendicular to the initial extension direction of the anti-rotation rod 201, so that when the stripping device 130 strips the tube sleeved on the core mold 200 and / or sleeves the tube on the core mold 200, the angle between the anti-rotation rod 201 and its initial extension direction is less than or equal to a preset angle. Wherein, the initial extension direction is the extension direction or pointing direction of the anti-rotation rod 201 when the stripping operation is not performed, that is, the initial extension direction of the anti-rotation rod 201 is not limited. Exemplarily, after the core mold 200 is fixed on the stripping device 100, when the core mold 200 is not subjected to the stripping operation or the sleeve operation, the extension direction or pointing direction of the anti-rotation rod 201 is the initial extension direction.

[0032] In some application scenarios, the shaft head at one end of the core mold 200 includes an anti-rotation rod 201. The initial extension direction of the anti-rotation rod 201 is the vertical direction. The anti-rotation mechanism 121 of the core mold clamping device 120 includes three first baffles 1212, two of which are respectively arranged on the left and right sides of the initial extension direction of the anti-rotation rod 201, and the two first baffles 1212 are arranged opposite to each other. The two first baffles 1212 are spaced apart by a preset length, and the preset length allows the anti-rotation rod 201 to pass through. The shaft head at one end of the core mold 200 is placed on the third first baffle plate 1212 of the anti-rotation mechanism 121, and the third first baffle plate 1212 is configured to move in the anti-rotation mechanism 121 so as to drive the core mold 200 to move in the anti-rotation mechanism 121, so that the anti-rotation rod 201 can be placed between the two first baffle plates 1212 and abut against the two first baffle plates 1212, so that when the stripping device 130 is stripping the tube sleeved on the core mold 200 and / or sleeves the tube on the core mold 200, the angle between the anti-rotation rod 201 and the initial extension direction is less than or equal to the preset angle, thereby effectively reducing the rotation or tilt of the core mold 200. The purpose of the preset angle is to allow the anti-rotation rod 201 to have a smaller activity space, allowing it to rotate within a certain range, and also to ensure that the maximum rotation angle or maximum tilt angle of the core mold 200 is controllable during the demoulding or sleeve process, thereby facilitating the sleeve or demoulding operation. The purpose of the preset angle in this solution is to enable the anti-rotation rod 201 to pass through the preset length between the two first baffles 1212 .

[0033] In some application scenarios, an anti-rotation rod 201 is provided at the shaft head at one end of the core mold 200. The initial extension direction of the anti-rotation rod 140 is the horizontal direction. The anti-rotation mechanism 121 of the core mold clamping device 120 includes two first baffles 1212, which are respectively located on the upper and lower sides of the anti-rotation rod 140. The first baffle 1212 located at the lower side of the anti-rotation rod 201 can be used to place the anti-rotation rod 201, and the first baffle 1212 is configured to move in the anti-rotation mechanism 121 so as to move the core mold 200 placed on the first baffle 1212 to abut against the first baffle 1212 located above the anti-rotation rod 201.

[0034] like Figure 2 As shown, the anti-rotation mechanism 121 further includes a guide plate 1211. The guide plate 1211 is fixedly disposed on the frame 110. The guide plate 1211 is connected to each baffle 1212.

[0035] In some embodiments, the guide plate 1211 includes a first guide plate 1211 and a second guide plate 1211 that are arranged opposite to each other. An anti-rotation rod 201 is provided on the shaft head at one end of the core mold 200, and the initial extension direction of the anti-rotation rod 201 is horizontal. Two first baffles 1212 are provided in the anti-rotation mechanism 121, and the two first baffles 1212 are arranged on the side of the first guide plate 1211 close to the anti-rotation rod 201, and the two first baffles 1212 are respectively located on the upper and lower sides of the anti-rotation rod 201. The first baffle 1212 located on the upper side of the anti-rotation rod 201 is fixedly connected to the first guide plate 1211, and the first baffle 1212 located on the lower side of the anti-rotation rod 201 is slidably connected to the first guide plate 1211 and the second guide plate 1211, so that the first baffle 1212 located on the lower side of the anti-rotation rod 201 can move between the first guide plate 1211 and the second guide plate 1211. Among them, the first baffle 1212 located at the lower side of the anti-rotation rod 201 can be used to place the core mold 200 and can move between the first guide plate 1211 and the second guide plate 1211 together with the core mold 200. The first baffle 1212 located at the lower side of the anti-rotation rod 201 drives the core mold 200 to rise, so that the anti-rotation rod 201 can abut against the first baffle 1212 on the upper side of the anti-rotation rod 201, so that when the stripping device 130 is demolding the pipe sleeved on the core mold 200 and / or sleeves the pipe onto the core mold 200, the angle between the anti-rotation rod 201 and the initial extension direction is less than or equal to the preset angle, thereby effectively reducing the rotation or tilt of the core mold 200.

[0036] In some application scenarios, an anti-rotation rod 201 is provided on the shaft head at one end of the core mold 200, and the initial extension direction of the anti-rotation rod 201 is the vertical direction. The anti-rotation mechanism 121 includes two guide plates 1211 and three first baffles 1212. The two guide plates 1211 are vertically fixed on the frame 110, and the guide plates 1211 are connected to the three first baffles 1212. Among them, the two first baffles 1212 are respectively arranged on the left and right sides of the initial extension direction of the anti-rotation rod 201, and are perpendicular to the initial extension direction of the anti-rotation rod 201. The anti-rotation rod 201 is allowed to pass between the two first baffles 1212, and the two first baffles 1212 are respectively fixed on the two guide plates 1211 and the two first baffles 1212 are arranged opposite to each other. In addition, the shaft head at one end of the core mold 200 is placed on the third first baffle plate 1212 of the anti-rotation mechanism 121. The third first baffle plate 1212 is movable, and the third first baffle plate 1212 and the two guide plates 1211 can be slidably connected.

[0037] It is understandable that the third first baffle plate 1212 can be moved on the guide plate 1211, and can be connected in other ways besides the sliding connection, which is not specifically limited here. The third first baffle plate 1212 can be used to place the core mold 200, and the first baffle plate 1212 is configured to move between the two guide plates 1211, so as to drive the core mold 200 to move between the two guide plates 1211, so that the anti-rotation rod 201 can be placed between the two first baffle plates 1212 and abut against the two first baffle plates 1212, so that when the stripping device 130 strips the tube sleeved on the core mold 200 and / or sleeves the tube onto the core mold 200, the angle between the anti-rotation rod 201 and the initial extension direction is less than or equal to the preset angle, thereby reducing the flipping or tilting angle of the core mold 200.

[0038] In some embodiments, see Figure 3 , Figure 3 yes Figure 2 In the enlarged schematic diagram at A1, the anti-rotation rod 201 of the core mold 200 includes at least a first anti-rotation rod 201-1 and a second anti-rotation rod 201-2, and the anti-rotation mechanism 121 of the core mold clamping device 120 includes at least a second baffle 1212-1 and a third baffle 1212-2. The second baffle 1212-1 is arranged on one side of the first anti-rotation rod 201-1, and the third baffle 1212-2 is arranged on one side of the second anti-rotation rod 201-2. Among them, the first anti-rotation rod 201-1, the second baffle 1212-1, the third baffle 1212-2 and the second anti-rotation rod 201-2 are arranged clockwise or counterclockwise, so that when the demolding device 130 demolds the tube sleeved on the core mold 200 and / or sleeves the tube onto the core mold 200, the angle between the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 and their respective initial extension directions is less than or equal to a preset angle.

[0039] For example, the anti-rotation rod 201 of the core mold 200 includes a first anti-rotation rod 201-1 and a second anti-rotation rod 201-2, and the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 are radially arranged on both sides of the axis head of the core mold 200. The anti-rotation mechanism 121 of the core mold clamping device 120 includes a second baffle plate 1212-1, a third baffle plate 1212-2, a fourth baffle plate (not shown), a first guide plate 1211 and a second guide plate 1211, and the first guide plate 1211 and the second guide plate 1211 are both vertically fixedly arranged on the frame 110, and the second baffle plate 1212-1 and the third baffle plate 1212-2 are fixedly connected to the first guide plate 1211 and the second guide plate 1211. The second baffle 1212-1 is arranged above the first anti-rotation rod 201-1, the third baffle 1212-2 is arranged above the second anti-rotation rod 201-2, the fourth baffle is rollingly connected with the first guide plate 1211 and the second guide plate 1211 and the fourth baffle is located below the first anti-rotation rod 201 and the second anti-rotation rod 201. Among them, the top of the fourth baffle is provided with an arc-shaped groove, and the arc-shaped groove and the shaft head of the core mold 200 are matched in size, and the shaft head of the core mold 200 can be placed in the arc-shaped groove of the fourth baffle. At the same time, the bottom of the second baffle 1212-1 and the third baffle 1212-2 is also provided with an arc-shaped groove, and the arc-shaped groove and the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 are matched in size. When the fourth baffle moves, it will drive the axis head of the core mold 200 to move in the direction of the second baffle 1212-1 and the third baffle 1212-2, and finally send the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 on the axis head of the core mold 200 into the arc-shaped groove at the bottom of the second baffle 1212-1 and the third baffle 1212-2, so that the second baffle 1212-1 and the third baffle 1212-2 are in contact with the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2. In the process of demolding the pipe sleeved on the core mold 200 and / or sleeved the pipe onto the core mold 200, the demolding device 130 can allow the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 to rotate within a certain range, thereby achieving the control of the maximum rotation angle or the maximum tilt angle, which is convenient for the sleeve or demolding operation.

[0040] For another example, the anti-rotation rod 201 of the core mold 200 includes a first anti-rotation rod 201-1, a second anti-rotation rod 201-2 and a third anti-rotation rod (not shown). The angles between the first anti-rotation rod 201-1, the second anti-rotation rod 201-2 and the third anti-rotation rod are 90° or 180°. Among them, the third anti-rotation rod is arranged on the shaft head of the core mold 200 in the vertical direction, the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 are arranged on the shaft head of the core mold 200 in the horizontal direction, and the anti-rotation mechanism 121 includes a second baffle 1212-1, a third baffle 1212-2, a fourth baffle (not shown), a fifth baffle (not shown), a sixth baffle (not shown) and a first guide plate 1211 and a second guide plate 1211. The first guide plate 1211 and the second guide plate 1211 are vertically arranged on the frame 110, the second baffle plate 1212-1 and the fourth baffle plate are fixedly arranged on the first guide plate 1211, and the third baffle plate 1212-2 and the fifth baffle plate are fixedly arranged on the second guide plate 1211. The fourth baffle plate and the fifth baffle plate are arranged on both sides of the third anti-rotation rod, the second baffle plate 1212-1 is arranged above the first anti-rotation rod 201-1, the third baffle plate 1212-2 is arranged above the second anti-rotation rod 201-2, and the sixth baffle plate is arranged below the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2, and the sixth baffle plate is used to place the shaft head of the core mold 200. The second baffle plate 1212-1, the third baffle plate 1212-2, the fourth baffle plate and the fifth baffle plate are fixedly connected to the guide plate 1211, and the sixth baffle plate is slidably connected to the guide plate 1211. The sixth baffle, the first anti-rotation rod 201-1, the second baffle 1212-1, the fourth baffle, the third anti-rotation rod, the fifth baffle, the third baffle 1212-2 and the second anti-rotation rod 201-2 may be arranged in a clockwise direction or a counterclockwise direction.

[0041] In some embodiments, continue to refer to Figure 2 The core mold clamping device 120 further includes a first driving mechanism 122, which is used to drive the core mold 200 to move toward the corresponding baffle 1212 or away from the corresponding baffle 1212, so as to abut against or away from the corresponding anti-rotation rod 201. Specifically, the first driving mechanism 122 further includes an upper hydraulic cylinder 1222 and an upper clamping seat 1221, and the upper clamping seat 1221 is slidably connected to the guide plate 1211, wherein the upper clamping seat 1221 is used to place the core mold 200, and the piston rod of the upper hydraulic cylinder 1222 is fixedly connected to the upper clamping seat 1221 to drive the upper clamping seat 1221 to slide on the guide plate 1211, so as to drive the core mold 200 to move in the direction toward the corresponding baffle or away from the corresponding baffle.

[0042] In some application scenarios, the upper clamping seat 1221 can be the baffle 1212 in the above-mentioned scheme that is slidably or rollingly connected to the guide plate 1211. The piston rod of the upper hydraulic cylinder 1222 is fixedly connected to the upper clamping seat 1221. The upper clamping seat 1221 can be used to place the core mold 200. Driven by the upper hydraulic cylinder 1222, the upper clamping seat 1221 and the core mold 200 placed on the upper clamping seat 1221 can be raised together until the anti-rotation rod 201 on the core mold 200 abuts against its corresponding baffle 1212, thereby clamping the core mold 200, thereby effectively reducing the rotation or tilting of the core mold 200 during the demolding / molding process.

[0043] In other application scenarios, the upper clamping seat 1221 can be connected to the baffle 1212 movable between the guide plates 1211. Specifically, the upper clamping seat 1221 can be fixedly connected to the bottom of the movable baffle 1212, so that when the upper hydraulic cylinder 1222 drives the upper clamping seat 1221 to move, the baffle 1212 can also be driven to move together, and the core mold 200 placed on the baffle 1212 can be driven to move together, so that the anti-rotation rod 201 on the core mold 200 abuts against the corresponding baffle 1212.

[0044] In some application scenarios, an anti-rotation rod 201 is provided on the shaft head at one end of the core mold 200. The end of the core mold 200 provided with the anti-rotation rod 201 is placed on the upper clamping seat 1221 of the core mold clamping device 120, and the end of the core mold 200 away from the core mold clamping device 120 is suspended. A first baffle 1212 is provided on the core mold clamping device 120, and the upper hydraulic cylinder 1222 drives the upper clamping seat 1221 and the core mold 200 to move toward the direction corresponding to the first baffle 1212 until the anti-rotation rod 201 abuts against the first baffle 1212.

[0045] The anti-rotation rod 201 and the first baffle 1212 can be allowed to rotate within a certain range, so as to control the maximum rotation angle or the maximum tilt angle, and facilitate the mold-mounting or demolding operation. It is understandable that in order to achieve a better mold-mounting or demolding effect and reduce the rotation or tilt of the core mold 200 during the mold-mounting or demolding process, there is no specific restriction on the number of anti-rotation rods 201 provided at one end or both ends of the core mold 200 in this solution.

[0046] See also Figure 2 and Figure 4 , Figure 4 yes Figure 1The enlarged schematic diagram at B in the figure. The stripping device 130 includes a retaining ring 131, a clamping mechanism 132 and a second driving mechanism 133. The retaining ring 131 is annular and is used to be sleeved on the outer periphery of the core mold 200 and abut the end of the pipe. The clamping mechanism 132 is used to clamp the retaining ring 131, and the second driving mechanism 133 is used to drive the clamping mechanism 132 to move along the axial direction of the core mold 200, thereby driving the retaining ring 131 and the pipe abutting against the retaining ring 131 to move along the axial direction of the core mold 200, so as to demold the pipe sleeved on the core mold 200 and / or sleeve the pipe onto the core mold 200.

[0047] Specifically, the inner diameter of the retaining ring 131 is slightly larger than the outer diameter of the core mold 200, so that it can be sleeved on the outer periphery of the core mold 200 and move freely on the core mold 200, and the inner diameter of the retaining ring 131 is smaller than the outer diameter of the pipe material, so that the retaining ring 131 can abut against the end of the pipe material. In order to facilitate the clamping of the clamping mechanism 132, the outer ring shape of the retaining ring 131 is usually circular, and can also be set to other shapes. At the same time, the structure of the retaining ring 131 in the clamping mechanism 132 should also be changed accordingly, as long as the clamping mechanism 132 can stably clamp the retaining ring 131, it is not limited here.

[0048] In other embodiments, the retaining ring 131 can be sleeved on the outer circumference of the core mold 200 , the inner ring shape of the retaining ring 131 must be the same as the shape of the core mold 200 or the tube, and it must be ensured that the retaining ring 131 can move freely on the core mold 200 .

[0049] In this embodiment, the retaining ring 131 can be an integrally formed structure. When the tube is demoulded, since the inner diameter of the retaining ring 131 is smaller than the outer diameter of the tube sleeved on the core mold 200, the retaining ring 131 cannot be sleeved from the end of the core mold 200 away from the core mold clamping device 120 to the end of the core mold 200 close to the core mold clamping device 120, so the retaining ring 131 needs to be sleeved on the end of the core mold 200 close to the core mold clamping device 120 before the core mold 200 is clamped by the core mold clamping device 120. In other embodiments, the retaining ring 131 can be set as a split structure that can be stably connected as a whole. The advantage is that the retaining ring 131 can be installed on the core mold 200 after the core mold 200 is clamped by the core mold clamping device 120, which can improve the installation accuracy and make the operation safer. When the pipe is molded, since the end of the core mold 200 away from the core mold clamping device 120 is suspended without any restrictions, the retaining ring 131 of the integrally formed structure can be freely installed, so there is no such restriction and requirement.

[0050] In some embodiments, the clamping mechanism 132 of the stripping device 130 includes two claws 1321 and a clamping seat 1323. The two claws 1321 are arranged on the clamping seat 1323 along the radial direction of the core mold 200. The clamping seat 1323 is slidably connected to the frame 110. The second driving mechanism 133 is arranged at the bottom of the clamping seat 1323. The second driving mechanism 133 is connected to the claws 1321. The second driving mechanism 133 is used to drive the two claws 1321 to move on the clamping seat 1323 along the radial direction of the core mold 200, so that the claws 1321 clamp or release the retaining ring 131.

[0051] For details, please refer to Figure 4 The clamping mechanism 132 includes two claws 1321, two claw support frames 1322 and a clamping seat 1323. The claw support frames 1322 are arranged on the clamping seat 1323 along the radial direction of the core mold, and the two claws 1321 are respectively installed on the opposite sides of the two claw support frames 1322, so that the two claws 1321 are also arranged along the radial direction of the core mold 200. When the two claw support frames 1322 move back and forth along the radial direction of the core mold 200, the two claws 1321 can clamp and release the retaining ring 131, and the clamping mechanism 132 applies the same force on both sides of the retaining ring 131 when clamping the retaining ring 131, avoiding the deviation of the retaining ring 131, so that the force acting on the pipe is more balanced and avoids damage to the pipe. The radial direction of the core mold 200 referred to in this application is the radial direction of the core mold 200 perpendicular to its axial direction on the horizontal plane.

[0052] The claws 1321 mounted on the claw support frame 1322 are detachable, and can be fixed by fastener connection or a clamping structure. The claws 1321 of different specifications can be replaced according to the retaining rings 131 of different specifications (mainly outer diameters), thereby improving the applicability of the equipment. The opposing surfaces of the two claws 1321 are arc-shaped, and can be adapted to retaining rings 131 of different specifications and sizes within a certain range. When the size of the retaining ring 131 changes within a small range, it can be applied without replacing the claws 1321, thereby improving work efficiency. At the same time, a flexible material is added to the contact surface between the claw 1321 and the retaining ring 131. Since the flexible material can bend elastically, the contact surface between the claw 1321 and the retaining ring 131 is increased, thereby increasing the friction between the claw 1321 and the retaining ring 131, and avoiding the clamping mechanism 132 and the retaining ring 131 from sliding relative to each other when the stripping device 130 moves due to the inability of the clamping mechanism 132 to be in close contact with the retaining ring 131, thereby affecting the demolding / sleeving effect, and also greatly reducing the probability of damage to the pipe during the demolding / sleeving process. The flexible material can be polyurethane or rubber, etc., which is not limited here.

[0053] In other embodiments, as the shape of the outer periphery of the retaining ring 131 changes, such as a square, the shape of the clamping surface of the claw 1321 also changes accordingly, as long as the claw 1321 can stably clamp the retaining ring 131.

[0054] Furthermore, a slide rail is provided on the frame 110 along the axial direction of the core mold 200, and a slider is provided on the bottom surface of the clamping seat 1323, which matches the slide rail on the frame 110, so that the clamping seat 1323 can move along the axial direction of the core mold 200 on the frame 110. The second driving mechanism 133 is provided on the bottom surface of the clamping seat 1323, and the second driving mechanism 133 drives the clamping seat 1323 to move along the axial direction of the core mold 200 on the frame 110, so that the clamping mechanism 132 moves along the axial direction of the core mold 200 as a whole, thereby driving the retaining ring 131 and the pipe abutting against the retaining ring 131 to move along the axial direction of the core mold 200.

[0055] Furthermore, a slide rail is arranged on the clamping seat 1323 along the radial direction of the core mold 200, and a slider is arranged on the claw support frame 1322. The slider on the claw support frame 1322 matches the slide rail on the clamping seat 1323, so that the claw support frame 1322 can move back and forth along the radial direction of the core mold 200 on the clamping seat 1323. A clamping motor (not shown) is arranged on the clamping seat 1323, and the clamping motor drives the two claw support frames 1322 to move toward each other, so that the two claws 1321 clamp the retaining ring 131 at the same time, and the clamping motor drives the two claw support frames 1322 to move away from each other, so that the two claws 1321 release the retaining ring 131 at the same time. Specifically, a gear is arranged on the clamping seat 133 between the two claw support frames 1322, and two racks are arranged on both sides of the gear to mesh with each other. The two racks are arranged parallel to each other and are respectively fixedly connected to the two claw support frames 1321 by fasteners. The clamping motor drives the gear to rotate and drives the rack to move, thereby driving the two claw support frames 1321 to move at the same time, thereby realizing the use of one clamping motor to drive the two claw support frames 1321 at the same time, which can avoid the use of two motors. The asynchronous motor startup caused by the use of the motors leads to uneven clamping force of the clamping mechanism 132 and the displacement of the retaining ring 131, thereby avoiding problems such as pipe rupture caused by eccentric clamping force.

[0056] In this embodiment, the second driving mechanism 133 and the clamping motor are both servo motors, and the servo motor can accurately control the moving distance.

[0057] In other embodiments, the two claw support frames 1322 can also be driven simultaneously by a cylinder. Specifically, a gear is arranged between the two claw support frames 1322, and two racks are arranged on both sides of the gear. The two racks are arranged in parallel with each other and are respectively fixedly connected to the two claw support frames 1322 by fasteners. The cylinder drives one of the claw support frames 1322 to move, driving the rack connected to the claw support frame 1322 to move, thereby driving the gear to move. The gear drives the other rack to move the same distance at the same time, so that the two claw support frames 1322 drive the two claws 1321 to move synchronously to achieve stable clamping. Of course, there are other driving methods, which are based on meeting actual needs, and the driving method is not limited here.

[0058] See also Figure 5 , Figure 5 This is a schematic diagram of the structure of another embodiment of the demoulding device of the present application. Currently, other demoulding devices 100 are mostly used to demould circular tubes. The radial angle requirement for circular tubes is not high when they are demoulded, but they are not suitable for elliptical tubes or other irregular tubes. At the same time, the demoulding force required for elliptical tubes is greater, which cannot be completed by conventional electric demoulding. Therefore, an auxiliary demoulding device 140 is added to the end of the frame 110 close to the core mold clamping device 120. Combined with Figure 6 , Figure 6 yes Figure 5 The enlarged schematic diagram at C in the middle. The auxiliary demoulding device 140 includes a hydraulic cylinder 1401 and an auxiliary baffle 1402. The piston rod of the hydraulic cylinder 1401 is fixedly connected to the auxiliary baffle 1402 by fasteners to drive the auxiliary baffle 1402 to move along the axial direction of the core mold 200, so that the auxiliary baffle 1402 abuts against the side of the baffle ring 131 away from the pipe, and drives the auxiliary baffle 1402 to drive the baffle ring 131 and the pipe abutting against the baffle ring 131 to move along the axial direction of the core mold 200. If the driving force of the second driving mechanism 133 in the stripping device 130 is too small to drive the clamping mechanism 132 to drive the retaining ring 131 and the pipe material abutting against the retaining ring 131 to move along the axial direction of the core mold 200, an auxiliary demoulding device 140 can be added, and the hydraulic cylinder 1401 of the auxiliary demoulding device 140 can drive the auxiliary baffle 1402 to move along the axial direction of the core mold 200, so as to drive the auxiliary baffle 1402 to drive the retaining ring 131 and the pipe material abutting against the retaining ring 131 to move along the axial direction of the core mold 200. The driving force of the hydraulic cylinder 1401 is large enough to release the close contact between the pipe material and the core mold 200. In this embodiment, the auxiliary demoulding device 140 directly acts on the retaining ring 131, and the force applied to the retaining ring 131 is more stable, so that the pipe material is easier to demould and is not damaged. In other embodiments, the auxiliary demoulding device 140 can also act on the clamping mechanism 132 to indirectly drive the retaining ring 131.

[0059] When the second driving mechanism 133 in the stripping device 130 can drive the clamping mechanism 132 to drive the retaining ring 131 and the pipe abutting against the retaining ring 131 to move along the axial direction of the core mold 200, the auxiliary demoulding device 140 does not operate, that is, the piston rod of the hydraulic cylinder 1401 does not extend, and the auxiliary baffle 1402 is located at the initial position and remains motionless; when the second driving mechanism 133 in the stripping device 130 drives the clamping mechanism 132 to apply force to the retaining ring 131, and still cannot release the close contact between the pipe and the core mold 200, the clamping mechanism 132 releases the retaining ring 131, and the second driving mechanism 133 drives the clamping mechanism 132 to move a certain distance away from the core mold clamping device 120. The moving distance is sufficient to ensure that the second driving mechanism 133 and the clamping mechanism 132 do not affect the operation of the auxiliary demoulding device 140, and the specific distance is not limited. After the second driving mechanism 133 and the clamping mechanism 132 move into place, the auxiliary demoulding device 140 starts to operate. The piston rod of the hydraulic cylinder 1401 drives the auxiliary baffle 1402 to move axially along the core mold 200, so that the auxiliary baffle 1402 abuts against the side of the retaining ring 131 away from the pipe, and drives the auxiliary baffle 1402 to drive the retaining ring 131 and the pipe abutting against the retaining ring 131 to move axially along the core mold 200 so that the pipe and the core mold 200 are released from close contact.

[0060] There are at least two hydraulic cylinders 1401 , and the hydraulic cylinders 1401 are arranged at intervals along the radial direction of the core mold 200 .

[0061] In this embodiment, two hydraulic cylinders 1401 are provided, which are respectively located on both sides of the core mold clamping device 120 along the radial direction of the core mold 200. Compared with one hydraulic cylinder 1401, the provision of two hydraulic cylinders 1401 makes the force applied to the auxiliary baffle 1402 more uniform and stable, and the force on both sides of the pipe is more consistent, making it easier for the pipe to release the tight contact with the core mold 200.

[0062] In other embodiments, the position and number of the hydraulic cylinder 1401 are not limited, as long as the auxiliary baffle 1402 can be driven to move axially along the core mold 200 .

[0063] A groove is provided on the auxiliary baffle 1402 to accommodate the core mold 200. The size of the groove on the auxiliary baffle 1402 can be slightly larger than the size of the core mold 200 to adapt to core molds 200 of different sizes, as long as the auxiliary baffle 1402 can abut against the retaining ring 131 and the groove on the auxiliary baffle 1402 cannot allow the retaining ring 131 to pass through. A slider matching the slide rail on the frame 110 is provided on the auxiliary baffle 1402 to facilitate the auxiliary baffle 1402 to move along the axial direction of the core mold 200 on the frame 110. The auxiliary baffle 1402 is connected to the slide rail on the frame 110 to play a guiding role, thereby avoiding the deviation of the auxiliary baffle 1402. The piston rod of the hydraulic cylinder 1401 is fixedly connected to the auxiliary baffle 1402 by fasteners, which is convenient for the installation and replacement of the auxiliary baffle 1402.

[0064] See also Figure 7 , Figure 7 Schematic diagram of the structure of the core mold of the present application. Figure 7 As shown, the core mold 200 includes: at least one anti-rotation rod 201, which is used to abut against the anti-rotation mechanism of the core mold clamping device, so that when the stripping equipment is demolding the pipe sleeved on the core mold 200 or sleeved the pipe onto the core mold 200, the relative position between the core mold 200 and the anti-rotation mechanism is fixed.

[0065] In some application scenarios, two anti-rotation rods 201 are provided at one end of the core mold 200, namely, a first anti-rotation rod 201-1 and a second anti-rotation rod 201-2, and the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 are arranged radially along the core mold 200. In the process of demolding the pipe sleeved on the core mold 200 or sleeved on the core mold 200, the end of the core mold 200 provided with the anti-rotation rod 201 is placed on the core mold clamping device of the stripping device, and driven by the upper hydraulic cylinder of the core mold clamping device, the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 move toward the direction close to their corresponding baffles until the first anti-rotation rod 201-1 and the second anti-rotation rod 201-2 abut against their corresponding baffles.

[0066] The above scheme, by setting at least one anti-rotation rod 201 on the core mold 200, makes the anti-rotation rod 201 abut against its corresponding baffle 1212 during the mold sleeve or demolding process, so that the anti-rotation rod 201 and its corresponding baffle 1212 are relatively fixed, thereby effectively reducing the rotation or tilting of the core mold 200, thereby improving the demolding efficiency of the pipe.

[0067] The pipe stripping device 100 of the present invention can be used to both sleeve the pipe on the outer periphery of the core mold 200 and remove the pipe on the outer periphery of the core mold 200, wherein the steps of sleeve mold include:

[0068] S11: Fix one end of the core mold 200 using the core mold clamping device 120 .

[0069] In some application scenarios, an anti-rotation rod 201 is provided at one end of the core mold 200. The end of the core mold 200 provided with the anti-rotation rod 201 is placed on the upper clamping seat 1221 in the core mold clamping device 120, and the piston rod of the upper hydraulic cylinder 1222 extends in the vertical direction to drive the upper clamping seat 1221 connected thereto to move between the two guide plates 1211, thereby enabling the core mold 200 to move between the two guide plates 1211. The upper hydraulic cylinder 1222 moves the core mold 200 upward in the vertical direction along the guide plates 1211 until the anti-rotation rod 201 at one end of the core mold 200 abuts against the first baffle plate 1212, thereby completing the clamping of the core mold 200.

[0070] In other application scenarios, two anti-rotation bars 201 are provided at one end of the core mold 200. Similarly, when the core mold clamping device 120 clamps the core mold 200, the two anti-rotation bars 201 on the core mold 200 are respectively abutted against the corresponding first baffles 1212, thereby completing the clamping of the core mold 200.

[0071] The core mold clamping device 120 is not limited to this type, and the core mold clamping device 120 in the prior art can be applicable to this method.

[0072] S12: Move the pipe and put it on the outer circumference of the core mold 200.

[0073] The pipe is sleeved on the outer periphery of the core mold 200 by manual handling, crane lifting or other equipment. When the pipe is sleeved on the core mold 200, the pipe can be manually pushed toward the core mold clamping device 120 for a certain distance until it cannot be pushed, thereby shortening the sleeve time.

[0074] S13: The tube is sleeved on the core mold 200 using the sleeve removal device 130 .

[0075] In some embodiments, the sleeve removal device 130 is moved to the end of the core mold 200 away from the core mold clamping device 120, and the retaining ring 131 is sleeved on the end of the core mold 200 away from the core mold clamping device 120, and the retaining ring 131 is abutted against the end of the tube away from the core mold clamping device 120. The clamping mechanism 132 clamps the retaining ring 131, and the second driving mechanism 133 drives the clamping mechanism 132 to move along the axial direction of the core mold 200 on the frame 110 toward the core mold clamping device 120, thereby driving the retaining ring 131 and the tube abutting against the retaining ring 131 to move along the axial direction of the core mold 200 toward the core mold clamping device 120, so that the tube is tightly sleeved on the outer periphery of the core mold 200.

[0076] Specifically, the clamping mechanism 132 includes two claws 1321, two claw support frames 1322 and a clamping seat 1323. The clamping seat 1323 is provided with a clamping motor. The clamping motor drives the two claw support frames 1322 to move toward each other along the radial direction of the core mold 200, so that the two claws 1321 clamp the retaining ring 131. The second driving mechanism 133 drives the clamping seat 1323 to move along the axial direction of the core mold 200 on the frame 110 toward the core mold clamping device 120, so that the clamping mechanism 132 moves along the axial direction of the core mold 200 toward the core mold clamping device 120, thereby driving the retaining ring 131 and the pipe abutting against the retaining ring 131 to move along the axial direction of the core mold 200 toward the core mold clamping device 120, so that the pipe is tightly fitted on the outer periphery of the core mold 200.

[0077] In one embodiment, the step of demoulding the pipe by the de-sleeving device 100 of the present solution includes:

[0078] S21: The retaining ring 131 is sleeved on one end of the core mold 200 so that the retaining ring 131 abuts against one end of the pipe material.

[0079] S22: placing the end of the core mold 200 provided with the retaining ring 131 on the core mold clamping device 120, and fixing the end of the core mold 200 provided with the retaining ring 131 by using the core mold clamping device 120.

[0080] The method of fixing the core mold 200 by the core mold clamping device 120 is consistent with the above step S11 and will not be repeated here.

[0081] In another embodiment, if the retaining ring 131 is a split structure, the core mold 200 can be first fixed by the core mold clamping device 120, and then the retaining ring 131 is sleeved on one end of the core mold 200 close to the core mold clamping device 120, depending on the specific situation.

[0082] S23: Demolding the tube using the stripping device 130 to release the tube from the close contact with the core mold 200.

[0083] Specifically, the clamping motor in the clamping mechanism 132 drives the two claw support frames 1322 to move toward each other along the radial direction of the core mold 200, so that the two claws 1321 clamp the retaining ring 131, and the second driving mechanism 133 drives the clamping seat 1322 to move on the frame 110 along the axial direction of the core mold 200 in the direction away from the core mold clamping device 120, so that the clamping mechanism 132 moves along the axial direction of the core mold 200 in the direction away from the core mold clamping device 120, thereby driving the retaining ring 131 and the pipe abutting against the retaining ring 131 to move along the axial direction of the core mold 200 in the direction away from the core mold clamping device 120, so that the pipe and the core mold 200 are released from close contact.

[0084] S24: Move the pipe so that the pipe is completely separated from the core mold 200.

[0085] Specifically, after the close contact between the pipe and the core mold 200 is released, a relatively small traction force is applied to the pipe to enable the pipe to move freely on the core mold 200. At this time, manual handling, crane lifting or other equipment can be used to completely separate the pipe from the core mold 200.

[0086] In another embodiment, the step of demoulding the pipe by the de-sleeving device 100 of the present application includes:

[0087] S31: The retaining ring 131 is sleeved on one end of the core mold 200 so that the retaining ring 131 abuts against one end of the pipe material.

[0088] S32: placing the end of the core mold 200 provided with the retaining ring 131 on the core mold clamping device 120, and fixing the end of the core mold 200 provided with the retaining ring 131 by using the core mold clamping device 120.

[0089] The method of fixing the core mold 200 by the core mold clamping device 120 is consistent with the above step S11 and will not be repeated here.

[0090] In another embodiment, if the retaining ring 131 is a split structure, the core mold 200 can be fixed by the core mold clamping device 120 first, and then the retaining ring 131 is sleeved on the core mold 200 close to one end of the core mold clamping device 120, depending on the specific situation.

[0091] S33: Demolding the tube using the stripping device 130. If the thrust of the stripping device 130 is insufficient, execute step S34; otherwise, execute step S35.

[0092] Specifically, the clamping motor drives the two claw support frames 1322 to move toward each other along the radial direction of the core mold 200, so that the two claws 1321 clamp the retaining ring 131, and the second driving mechanism 133 drives the clamping seat 1323 on the frame 110 to move along the axial direction of the core mold 200 in a direction away from the core mold clamping device 120, so that the clamping mechanism 132 moves along the axial direction of the core mold 200 in a direction away from the core mold clamping device 120.

[0093] S34: Start the auxiliary demoulding device 140 to continue demoulding, and execute step S35 after the close contact between the pipe and the core mold 200 is released.

[0094] Since the driving force of the second driving mechanism 133 is too small, the clamping mechanism 132 cannot be driven to drive the retaining ring 131 and the pipe abutting against the retaining ring 131 to move axially along the core mold 200. At this time, the clamping mechanism 132 loosens the retaining ring 131. For example, the clamping mechanism 132 is loosened to a size larger than 80 mm of the outer diameter of the pipe. The second driving mechanism 133 drives the clamping mechanism 132 on the frame 110 to move along the axial direction of the core mold 200 away from the core mold clamping device 120 and move to the tail end of the removal equipment 100. The auxiliary demoulding device 140 starts to operate, and the hydraulic cylinder 1401 of the auxiliary demoulding device 140 drives the auxiliary baffle 1402 to move along the axial direction of the core mold 200, so that the auxiliary baffle 1402 abuts against the side of the retaining ring 131 away from the pipe, and drives the auxiliary baffle 1402 to drive the retaining ring 131 and the pipe abutting against the retaining ring 131 to move along the axial direction of the core mold 200 away from the core mold clamping device 120, so that the pipe and the core mold 200 are released from close contact.

[0095] S35: Move the pipe so that the pipe is completely separated from the core mold 200.

[0096] Specifically, after the close contact between the pipe and the core mold 200 is released, a relatively small pulling force is applied to the pipe to make the pipe move freely on the core mold 200. At this time, manual handling, crane lifting or other equipment can be used to completely separate the pipe from the core mold 200. After the demoulding is successful, the sleeve core mold 200 can be lifted out by a lifting device and run to the next process point.

[0097] The beneficial effects of the present application are as follows: the present application sets an anti-rotation mechanism on the core mold clamping device to cooperate with the anti-rotation rod on the core mold, which can be used for demolding / molding of pipes of different shapes, and also reduces the situation where the core mold rotates or tilts during the demolding / molding process, thereby expanding the scope of application of the demolding device of the present application. At the same time, the present application scheme sets a retaining ring that can be sleeved on the outer periphery of the core mold and abuts against the end of the pipe, and adopts a clamping mechanism to clamp the retaining ring. The driving mechanism drives the clamping mechanism to move along the axial direction of the core mold on the frame, thereby driving the retaining ring and the pipe abutting against the retaining ring to move along the axial direction of the core mold. By clamping the retaining ring and driving the retaining ring to move, thereby driving the pipe to move, the pipe rupture caused by directly clamping the pipe can be avoided, and the demolding device can be moved on the frame, and both the requirements of molding and demolding are met at the same time, with low cost and wide application range.

[0098] The present application also discloses an auxiliary demoulding device. If the driving force of the driving mechanism in the demoulding device is too small to drive the clamping mechanism to drive the retaining ring and the pipe abutting the retaining ring to move axially along the core mold, an auxiliary demoulding device can be added. The hydraulic cylinder of the auxiliary demoulding device can drive the baffle to move axially along the core mold, so as to drive the baffle to drive the retaining ring and the pipe abutting the retaining ring to move axially along the core mold. The driving force of the hydraulic cylinder is relatively large, which is sufficient to release the close contact between the pipe and the core mold.
