Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a pressure vessel reinforced head and a processing device thereof. Background Art

[0002] A pressure vessel refers to a container that is under pressure, such as a boiler, storage tank, reactor, etc. The container head is used to close the port of the container to ensure that the material inside the container does not leak out or to prevent the inside of the container from being affected by the outside world. It is an important component of the pressure vessel.

[0003] Common reinforced heads include the following: elliptical head: usually used at both ends of cylindrical containers; cylindrical head: usually used on special containers such as reactors; conical head: used to connect two cylinders at the end of the container or in the middle of the container; spherical head: a relatively sturdy head, usually used on the top of storage tanks and pressure vessels, can withstand higher pressure and has better safety performance.

[0004] The processing of spherical heads usually uses hot pressing technology, which mainly includes the following steps: material preparation: select carbon steel, stainless steel, alloy steel, etc., and cut out head plates of suitable size. The plates used to make spherical heads are round plates; plate heating: use a heating furnace to heat the round plates until they are red; hot pressing forming: place the red-hot plate on the mold, and use a punch to punch the plate once to form a semi-finished product. During the first punching process, black impurity particles will be produced on the surface of the plate due to oxidation and sintering. The impurities need to be removed and then a second punching is performed to form the spherical head and place it on the ground. Then use a hook to lift the mold to expose the formed spherical head for easy transportation by forklift.

[0005] At present, when the existing technology processes the spherical head, a forklift is usually used to transfer the red-hot plate to the mold. This process requires manual hand-held tools to assist and position the plate, and it is also necessary to manually remove impurities sintered on the surface of the plate. However, the plate size is large and the temperature of the red-hot plate is high, which can easily cause safety hazards to workers, and manual operation is time-consuming and labor-intensive, which can easily affect processing efficiency.

[0017] The present invention has the following beneficial effects: 1. The pressure vessel reinforced head processing device transports the plate to the upper side of the mold by a forklift, and presses one side of the plate against the side of the first limiting piece, and the lower side of the plate is pressed against the upper side of the support block, so that the forklift places the plate on the mold, and a gap is left between the plate and the mold due to the support of the support block, which is convenient for the forklift to withdraw from between the plate and the mold, and then the punch head descends, so that the support block descends to the inside of the mold, so that the plate is placed flat on the upper side of the mold, and as the punch head continues to descend, the second limiting pieces on both sides move inward with the center of the mold as the center of the circle, thereby pushing the plate offset from the mold to move until the center of the plate and the center of the mold are on the same vertical line; The punch head that continues to descend presses down on the plate, and through the cooperation of the punch head and the mold, the plate is deformed by the punching, thereby performing a punching on the plate. Subsequently, the punch head moves up, and the first motor drives the scraper to rotate, so that the scraper contacts and fits against the surface of the plate. The second motor drives the rotating gear to rotate, and through the engagement of the rotating gear and the tooth groove, the circular ring is driven to rotate, so that the circular ring drives the scraper to rotate on the surface of the plate, thereby scraping off the sintered impurities generated on the surface of the plate due to the first punching. Finally, the scraper is reset, and the punch head descends again to perform a second punching on the plate, thereby punching the plate into a head body, thereby effectively improving the processing efficiency.

[0018] 2. The pressure vessel strengthened head processing device, the punching head drives the second rack to descend, so that the second rack is engaged with the thick gear, driving the thick gear to rotate, and then through the engagement of the thick gear with the first rack, the first rack and the second limit plate are driven to move. At the same time, the connecting rod drives the first wedge block to move, and through the coordinated use of the first wedge block and the second wedge block, the second wedge block drives the support block to descend to the inside of the mold, so that the plate is placed flat on the upper side of the mold, and then the second limit plate pushes the plate so that the center of the plate and the center of the mold are on the same vertical line. In summary, in the process of the punching head descending, it is convenient to make the support block descend and the second limit plate move, so as to facilitate the position calibration of the plate on the mold, thereby improving the stamping quality of the head body.

[0019] 3. The pressure vessel reinforced head processing device rotates the rotating gear, and through the cooperation of the first straight rod and the second straight rod, the piston is driven to reciprocate in the cylinder. When the piston is pulled outward in the cylinder, the air at the suction port enters the cylinder through the connecting pipe, the waste box, the connecting pipe and the first one-way valve in sequence, thereby forming a negative pressure at the suction port, and the impurities scraped off by the scraper are sucked into the cavity of the scraper. The impurities are then collected into the waste box through the connecting pipe.

[0033] A first limiting plate 120 is fixedly installed on the upper side of the mold 100, a support block 130 is slidably arranged on the upper side of the mold 100, a second limiting plate 140 is movably arranged on the outer side of the mold 100, the first limiting plate 120 and the second limiting plate 140 are used to limit the plate 1, a circular ring 180 is rotatably sleeved on the outer side of the mold 100, a fixing frame 181 is fixedly installed on the outer side of the circular ring 180, a mounting rod 182 is rotatably arranged on the side of the fixing frame 181, a first motor 183 is fixedly installed on the outer side of the fixing frame 181, and the output shaft of the first motor 183 is drivingly connected to the mounting rod 182.

[0034] A scraper 184 is fixedly installed on the outside of the mounting rod 182. The scraper 184 is used to scrape off sintered impurities generated after the plate 1 is punched once. A blade 185 is arranged on the outside of the scraper 184 for scraping off impurities. A suction port 186 is opened on the side of the scraper 184. The suction port 186 is arranged on the upper side of the blade 185. The inside of the scraper 184 is arranged as a cavity connected to the suction port 186. A connecting pipe 187 is installed on the outside of the scraper 184. The connecting pipe 187 is connected to the cavity inside the scraper 184.

[0035] A second motor 190 is fixedly installed on the outside of the mold 100 , and a rotating gear 191 is fixedly installed on the output shaft of the second motor 190 . A tooth groove 192 meshing with the rotating gear 191 is opened on the side of the ring 180 , and the tooth groove 192 is evenly opened on the side of the ring 180 in a circumferential direction.

[0036] This embodiment also provides a reinforced head for a pressure vessel, wherein the head comprises a head body 2, and the head body 2 is manufactured by a reinforced head processing device for a pressure vessel.

[0037] In this embodiment: the plate 1 is transported to the upper side of the mold 100 by a forklift, one side of the plate 1 is pressed against the side of the first limiting piece 120, and the lower side of the plate 1 is pressed against the upper side of the support block 130, so that the forklift places the plate 1 on the mold 100, and a gap is left between the plate 1 and the mold 100 due to the support of the support block 130, so that the forklift can withdraw from between the plate 1 and the mold 100, and then the punch head 110 descends, so that the support block 130 descends to the inner side of the mold 100, so that the plate 1 is placed flat on the upper side of the mold 100, and as the punch head 110 continues to descend, the second limiting pieces 140 on both sides move inward with the center of the mold 100 as the center of the circle, thereby pushing the plate 1 offset from the mold 100 to move until the center of the circle of the plate 1 and the center of the mold 100 are on the same vertical line; The punch head 110 that continues to descend presses down on the plate 1. Through the cooperation of the punch head 110 and the die 100, the plate 1 is deformed by punching, thereby performing a punching operation on the plate 1. Subsequently, the punch head 110 moves upward, and the first motor 183 drives the scraper 184 to rotate, so that the scraper 184 contacts and fits the surface of the plate 1. The second motor 190 drives the rotating gear 191 to rotate, and through the meshing of the rotating gear 191 and the tooth groove 192, the ring 180 is driven to rotate, so that the ring 180 drives the scraper to rotate on the surface of the plate 1, thereby removing the sintered impurities generated on the surface of the plate 1 due to the first punching operation. The scraper 184 is reset and the punch head 110 is lowered again to perform secondary punching on the plate 1, so that the plate 1 is punched into the head body 2, thereby effectively improving the processing efficiency and solving the problem that when the prior art processes the spherical head, a forklift is usually used to transfer the red-hot plate to the mold. This process requires manual hand-held tools to assist and position the placement of the plate, and it is also necessary to manually remove impurities sintered on the surface of the plate. However, the plate is large in size and the temperature of the red-hot plate is high, which may easily cause safety hazards to workers, and manual operation is time-consuming and labor-intensive, which may easily affect the processing efficiency.

[0038] It should be noted that: the plate 1 is made into the head body 2 after two stampings, and then the hook connected to the lifting system is hung on the hanging ring 102, the mold 100 is lifted upward, and the head body 2 on the ground is exposed, so that the head body 2 can be transferred and transported by a forklift; the lifting system can use a hydraulic cylinder or a winch, which are technical means well known to technicians in this field and will not be elaborated here.

[0039] Embodiment 2: This embodiment is intended to promote the solution of the problem that during the descent of the punch head 110, it is not convenient to make the support block 130 descend and the second limit plate 140 move, so it is not convenient to calibrate the position of the plate 1 on the mold 100, which easily affects the quality of the head body 2. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Fig. 9 The number of the support blocks 130 and the second limiting plates 140 are both set to two, and the two support blocks 130 are symmetrically arranged on the side of the mold 100 with respect to the first limiting plate 120.

[0040] A shell 150 is fixedly installed on the outside of the mold 100. The number of shells 150 is set to two. The two shells 150 are respectively arranged on the sides of the two support blocks 130. Connecting rods 151 are slidably inserted on the sides of the shells 150. A first wedge block 152 is slidably arranged on the inside of the shell 150. One end of the connecting rod 151 located in the shell 150 is fixedly connected to the first wedge block 152.

One end of the first spring 153 is fixedly connected to the first wedge block 152, and the other end of the first spring 153 is fixedly connected to the inner wall of the shell 150.

[0041] A second wedge block 160 is slidably provided on the inner side of the mold 100, and the second wedge block 160 is used in conjunction with the first wedge block 152. A slider 161 is fixedly installed on the inclined surface of the second wedge block 160, and a slide groove 162 for use with the slider 161 is provided on the inclined surface of the first wedge block 152. The slider 161 is slidably inserted in the slide groove 162, and the slider 161 is set to be a sphere to prevent the first wedge block 152 from separating from the second wedge block 160. The second wedge block 160 is fixedly connected to the bottom of the support block 130.

[0042] A first rack 163 is fixedly installed at one end of the connecting rod 151 located outside the shell 150, and the end of the first rack 163 is fixedly connected to the second limit plate 140. A support shaft 164 is fixedly installed on the outside of the mold 100, and a thick gear 165 is rotatably set on the end of the support shaft 164. The bottom of the thick gear 165 is intermittently meshed with the first rack 163. A second rack 166 is fixedly installed on the outside of the punch head 110, and the second rack 166 is intermittently meshed with the side of the thick gear 165. The second rack 166 is staggered with the first rack 163 to prevent the first rack 163 from obstructing the lifting and lowering of the second rack 166.

[0043] A third wedge block 170 is fixedly installed on the lower side of the connecting rod 151, and a fourth wedge block 171 is slidably arranged on the inner side of the shell 150. The fourth wedge block 171 is intermittently used in conjunction with the third wedge block 170. A fifth wedge block 172 is fixedly connected to the outer side of the fourth wedge block 171. An insertion rod 173 is slidably inserted on the lower side of the shell 150. The top of the insertion rod 173 is fixedly connected to the bottom of the fourth wedge block 171.

[0044] In this embodiment: the punch head 110 drives the second rack 166 to descend, so that the second rack 166 is meshed with the thick gear 165, driving the thick gear 165 to rotate, and then through the meshing of the thick gear 165 with the first rack 163, the first rack 163 and the second limiting plate 140 are driven to move. At the same time, the connecting rod 151 drives the first wedge block 152 to move, and through the cooperation of the first wedge block 152 and the second wedge block 160, the second wedge block 160 drives the support block 130 to descend to the inner side of the mold 100, so that the plate 1 is placed flat on the upper side of the mold 100, and then the second limiting plate 140 pushes the plate 1 so that the center of the plate 1 is on the same vertical line as the center of the mold 100. In summary, in the process of the punch head 110 descending, it is convenient to make the support block 130 descend and the second limiting plate 140 move, so as to facilitate the calibration of the position of the plate 1 on the mold 100, thereby improving the stamping quality of the head body 2; Moreover, when the first rack 163 drives the connecting rod 151 to move, the third wedge block 170 moves with the connecting rod 151, so that the third wedge block 170 conflicts with the fourth wedge block 171, so that the fourth wedge block 171 drives the fifth wedge block 172 to descend, and the second spring 174 is compressed. Subsequently, the second rack 166 continues to descend, and the toothless portion on the upper side of the second rack 166 approaches the side of the thick gear 165, so that the second rack 166 is disengaged from the thick gear 165. At this time, the third wedge block 170 passes over the fourth wedge block 171, and under the action of the rebound force of the second spring 174, the fourth wedge block 171 and the fifth wedge block 172 move up. Resetting, through the fifth wedge block 172, the third wedge block 170 is pressed against the third wedge block 170, so that the third wedge block 170 drives the connecting rod 151 and the first rack 163 to move away from the thick gear 165, so that the first rack 163 and the thick gear 165 are also disengaged, to prevent the second rack 166 from affecting the first rack 163 and the support block 130 through the thick gear 165 when the punch head 110 rises and resets. After the stamping is completed, the insertion rod 173 is pulled downward to release the fifth wedge block 172 from the third wedge block 170, so that the third wedge block 170 can be moved back and reset, thereby resetting the support block 130 and the second limit plate 140.

The end of the connecting pipe 211 is connected to the first one-way valve 204, and the end of the connecting pipe 187 is connected to the waste box 210. The scraper 184, the connecting pipe 187, the waste box 210, the connecting pipe 211 and the piston 201 are all resistant to high temperatures to prevent them from being scalded by the high-temperature plate 1 and impurities.

[0047] In this embodiment: the rotating gear 191 rotates, and through the cooperation of the first straight rod 202 and the second straight rod 203, the piston 201 is driven to reciprocate in the cylinder 200. When the piston 201 is pulled outward in the cylinder 200, the air at the suction port 186 enters the cylinder 200 through the connecting pipe 187, the waste box 210, the connecting pipe 211 and the first one-way valve 204 in sequence, thereby forming a negative pressure at the suction port 186, and the impurities scraped off by the scraper 184 are sucked into the cavity of the scraper 184, and the impurities are then collected into the waste box 210 through the connecting pipe 187. When the piston 201 is pushed inward in the cylinder 200, the air in the cylinder is discharged to the outside through the second one-way valve 205, thereby facilitating the removal of the impurities scraped off by the scraper 184 from the plate 1.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
