Description

TECHNICAL FIELD

[0001] The application relates to the technical field of tank stamping equipment, in particular to tank stamping equipment for liquefied petroleum gas tank processing. BACKGROUND

[0002] The gas tank refers to equipment specially used for storing gas and simultaneously used for stabilizing system pressure. The gas tank can be divided into high-pressure gas tanks, low-pressure gas tanks and normal-pressure gas tanks according to different pressure bearing capacities. The gas tank usually comprises a cylinder, a head, a flange, a connecting pipe, a sealing element and a support and the like, and the cylinder of the gas tank can be integrally cast or separately stamped and formed and then welded. Since the integrally cast forming usually has a higher cost, the separately stamped forming has a lower cost, and therefore the separately stamped forming is usually used to produce the cylinder of the gas tank.

[0003] A patent file with the publication number CN222931701U discloses a vacuum tank stamping equipment which comprises an equipment box, a sliding rod arranged on the top of the equipment box, a top plate arranged on the top of the sliding rod, a hydraulic cylinder arranged on the top of the top plate, a moving plate arranged on the bottom of the hydraulic cylinder, a limiting assembly arranged on the bottom of the moving plate, the limiting assembly comprising a mounting ring, a clamping groove, a first spring, a clamping plate, a pad plate, an electric push rod and a clamping plate, the bottom of the moving plate being fixedly connected with the mounting ring, the bottom of the mounting ring being provided with the clamping groove, the inside of the clamping groove being fixedly connected with the first spring, and one end of the first spring being fixedly connected with the clamping plate.

[0004] In view of the related technology, the above-mentioned equipment can only form a half tank body each time, and since two tank bodies need to be butt-welded to form a whole gas tank, and an installation hole for installing a valve is needed to be arranged in the middle of the circular arc part of one of the tank bodies, the stamping and the punching are usually performed in steps, and an additional centering operation is needed to be performed when the punching is performed, which is low in efficiency. SUMMARY

[0005] In order to facilitate the synchronous stamping and punching of the tank body and improve the production efficiency, the application provides tank stamping equipment for liquefied petroleum gas tank processing.

[0006] The tank stamping equipment for liquefied petroleum gas tank processing provided by the application adopts the following technical scheme:

[0008] The punching die is also provided with a punching head in a lifting manner, the avoiding head and the punching head are movably opposite, and the punching head is movably penetrated and arranged in the punching groove;

[0009] The punch head is lifted once, the switching assembly switches the forming die corresponding to the punch head to the position corresponding to the punch head and the punching die, or switches the punching die corresponding to the punch head to the position corresponding to the punch head and the forming die;

[0010] When the forming die and the punch head correspond, the adjusting assembly adjusts the avoiding head to be always flush with the surface of the punch head;

[0011] When the punching die and the punch head correspond, the adjusting assembly adjusts the avoiding head to be immersed in the punch head.

[0012] By adopting the above technical scheme, when the gas tank is pressed and formed, the raw material plate to be pressed is placed on the installation platform first, the installation platform is rotated to convey the raw material plate, until the plate is conveyed under the punch head, then the punch head is lowered to press the raw material plate into the forming die / punching die for forming.

[0013] If the punch head is lowered to press and form the raw material plate into the forming die, the forming tank body does not need to be punched, so that the lower tank body can be formed by press forming.

[0014] After the upper tank body is formed by the stamping, the stamping head is lifted, and when the stamping head is lowered again, the mounting table is rotated to a position corresponding to the punching die and the stamping head at this time, and when the stamping head is lowered to press and form the raw material plate into the shape of the tank body in the punching die, the avoidance head is unlocked at this time, and the punching head on the punching die is ejected from the punching groove to punch the already formed tank body arc part at this time. The part of the already formed tank body is still in the punching die, and no additional centering operation is required when the punching head punches the tank body, and the punching operation of the tank body is automatically realized during the lowering of the stamping head, forming the upper tank body, which is high in processing efficiency and does not require an additional power source, saving power.

[0015] At the same time, the rotation period of the mounting table is coordinated with the lifting period of the stamping head through the setting of the switching assembly, and the rotation of the mounting table is automatically realized when the stamping head is lifted and lowered, thereby realizing the synchronous forming of the upper tank body and the lower tank body.

[0016] At the same time, the punching head is selectively corresponding to the forming die and the punching die, and the processing of the lower tank body and the upper tank body is realized through the same device, thereby improving the adaptability of the device and reducing the production cost of the gas storage tank.

[0017] Further, when the switching of stamping and punching is required, the unlocking of the punching head and the avoidance head is realized through the setting of the adjusting assembly, thereby realizing the punching operation of the upper tank body.

[0018] Optionally, the switching assembly comprises a mounting rod arranged on the mounting table, the mounting rod is rotationally arranged on the workbench, a synchronous gear ring is coaxially arranged on the rotating rod, a synchronous gear is arranged on the workbench and engaged with the synchronous gear ring, a synchronous sleeve is rotationally arranged on the synchronous gear, a rotation limiting structure is arranged between the synchronous sleeve and the synchronous gear, the synchronous gear rotates when the synchronous sleeve rotates forward, and the synchronous gear does not rotate when the synchronous sleeve rotates reversely, a mounting rod connected with the stamping head is arranged on the rack, the mounting rod is movably inserted into the synchronous sleeve, a fixed block is fixedly arranged on the outer circumferential wall of the mounting rod, a limiting groove is formed in the synchronous sleeve, and the limiting groove is obliquely arranged along the height direction of the synchronous sleeve.

[0019] Because the stepping motor and the PLC control circuit are usually used in the conventional technical means to realize the periodic switching, and in the process of converting the production rhythm from manual control to automatic control of the old stamping equipment, if the old equipment is completely abandoned, the initial cost is high, and when the stepping motor and the PLC control circuit are used to customize the new stamping equipment, the cost is high, and the debugging needs to be continuously adjusted, which affects the production rhythm and the production cost, and the transmission ratio of the gear and the gear ring can be adjusted to improve the old equipment, and the production rhythm is converted from manual control to semi-automatic control, and the cost is relatively low.

[0020] Because metal dust and electromagnetic interference are generated during stamping and punching, the stepping motor is prone to step loss and encoder signal interference.

[0021] By adopting the above technical scheme, during the descending process of the stamping head, the mounting rod connected with the stamping head descends and inserts into the synchronous sleeve, at this time, the mounting rod inserts into the synchronous sleeve, the fixed block inserts into the limiting groove, at this time, under the action of the limiting groove, when the mounting rod continues to descend, the fixed block is not easy to deviate, because the limiting groove is inclined, when the fixed block continues to descend, the synchronous sleeve is reversely rotated, at this time, the same gear does not rotate, after the stamping forming, during the ascending process of the mounting rod, the limiting groove rotates during the fixed ascending process, thereby driving the synchronous sleeve to rotate forward, the synchronous sleeve rotating forward drives the same gear to rotate, thereby realizing the rotary driving of the mounting table, at this time, the switching of the forming die and the punching die is realized, the switching of the stamping forming and the punching forming is realized, and the switching of the mounting table is automatically realized during the ascending and descending of the stamping head.

[0022] The power of the stamping head descending is directly converted into the kinetic energy of the mounting table rotating by adopting the above structure, the mounting table is driven to rotate, the action connection time is short, when the periodic switching is realized by the above structure, the wear of the synchronous sleeve, the lubrication of the same gear and the synchronous gear ring affect the transmission precision, the maintenance cost is much lower than the replacement cost of the encoder and the filter capacitor of the driver, and the comprehensive cost of the mechanical transmission is low in the production of the gas tank and other products with low precision requirements and large quantities.

[0026] By adopting the above technical scheme, when the punching die and the punch head correspond, the abutting block and the limiting block are abuttingly matched and abutted during the lowering of the punch head, the abutting block abuts and slides against the limiting block during the lowering of the punch head, the limiting block is abuttingly matched and abutted with the inclined side of the adjusting hole, the limiting block abuts and slides against the inclined side of the adjusting hole during the lowering of the punch head, the limiting rod is driven to slide towards the direction away from the limiting groove, the adjusting block is unlocked, the avoiding head is unlocked, and the precise perforation of the upper tank body is realized.

[0027] When the forming die and the punch head correspond, the limiting rod is not easy to slide during the lowering of the punch head because there is no abutting block on the outer circumferential side of the forming die, the limiting rod is always located in the limiting groove, the adjusting block and the avoiding head are always limited, and the avoiding head is not easy to easily sink into the punch head.

[0028] Optionally, the forming die and the punching die are both provided with two, and the forming die and the punching die are sequentially and adjacently arranged at intervals, the machine frame is further provided with a coating piece for coating lubricating oil on the upper surface of the punching die, the coating piece comprises a coating block arranged on the machine frame and a liquid storage tank arranged on the machine frame, the liquid storage tank stores lubricating oil, the bottom side of the coating block is provided with a coating hole, and the coating hole is provided with an opening and closing piece.

[0031] By adopting the technical scheme, the forming die and the punching die are driven to rotate during the rotation of the installation table, when the forming die / punching die is rotated to the coating block, the upper surface of the forming die / punching die is fitted and abutted with the inclined side of the sealing block, so that the sealing block is immersed in the coating hole, and the lubricating oil in the liquid storage tank falls to the surface of the forming die / punching die through the coating hole at this time, realizing lubrication and coating of the forming die / punching die before feeding.

[0032] Since the width of the end side of the sealing block is smaller than the opening width of the coating hole, when the sealing block is immersed in the coating hole, the sealing block cannot completely block the coating hole at this time, so that the lubricating oil falls to the surface of the forming die / punching die from the coating hole;

[0040] 2. Through the setting of a synchronous gear, a synchronous gear ring meshing with the synchronous gear, a synchronous sleeve set with the synchronous gear, and a mounting rod set on the frame, when the punch head descends and drives the limit block on the mounting rod to descend, the synchronous sleeve is driven to rotate forward or reverse under the action of the limit groove. When the synchronous sleeve rotates forward, it drives the synchronous gear ring and the synchronous gear to rotate, thereby matching the lifting cycle of the punch head with the rotation cycle of the mounting table, so that the switching between the forming die and the punching die can be achieved with each lifting of the punch head;

[0041] 3.

[0063] When the surface of the forming die 21 / stamping die is in contact with the sealing block 361, and the opening of the forming die 21 / stamping die corresponds to the sealing block 361, the sealing block 361 is not easily submerged in the coating block 352, and the lubricating oil is not easily wasted. By setting multiple sets of coating blocks 352, different degrees of coating are applied to different parts of the forming die 21 / stamping die, while reducing the application of lubricating oil to the inner surface of the forming die 21 / stamping die, thereby reducing carbon deposits on the inner surface of the die. At the same time, the application of lubricating oil to the inner surface of the die affects the appearance of the stamped part and may also interfere with subsequent surface treatment processes and affect the adhesion of subsequent coatings. Therefore, the inner surface of the forming die 21 / stamping die is often not coated with lubricating oil.

[0064] The implementation principle of the tank pressing equipment for liquefied petroleum gas tank processing provided in the embodiments of the present application is as follows: when the upper and lower tank bodies are subjected to punch forming, relevant technical personnel place the raw material plate on the mounting table 2, and the raw material plate is limited by the limiting block 26; in the equipment operation cycle, the switching assembly 4 drives the mounting table 2 to rotate by 90° every time the punch head 11 completes one lifting action, and the forming die 21 and the punching die 22 are synchronously implemented to alternately work. In the descending stage of the punch head 11, the adjusting assembly 3 automatically adjusts the position of the avoiding head 13 according to the current work station, and the punching head 25 is driven by the gear transmission system to complete accurate punching.

[0065] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
