[0020] The docking structure 1 of the embodiment can realize two modes of "single tank body use" or "double tank body combination use" according to the length of the workpiece, and the specific working process of the double tank body combination use (i.e. the first tank body 17 and the second tank body 18 are docked and lengthened) is as follows: High pre-adjustment stage: start two pairs of first hydraulic cylinders 10 to make the extension and retraction ends of the first hydraulic cylinders 10 synchronously extend or shorten, drive the mounting seat 11, the first overturning arm 12, the second overturning arm 13 and the first bearing seat 16 to move up and down as a whole, until the bottom of the first tank body 17 and the second tank body 18 is at a preset height from the ground, to avoid interference between the tank body and the mounting box 6 or the ground in the subsequent overturning process, and after the adjustment is completed, the first hydraulic cylinder 10 remains in the current extension and retraction state, and the height position is locked.

[0021] Overturning and shifting stage: start a pair of second hydraulic cylinders 19 to synchronously extend the extension and retraction ends of the second hydraulic cylinders 19, and push the left first overturning arm 12 hinged thereto to rotate around the pin shaft of the mounting seat 11; since the two pairs of first overturning arms 12 are designed in reverse symmetry, the rotation of the left first overturning arm 12 will drive the right first overturning arm 12 to synchronously and reversely rotate through the linkage structure; The first overturning arm 12 on the upper side drives the upper docking plate 14, the first sliding rail 15 and the first bearing seat 16, so that the first tank body 17 is slightly lifted upward and moves to the left, reserving space to the right for the shifting of the second tank body 18; The first overturning arm 12 on the lower side drives the second overturning arm 13 to synchronously rotate, and the second overturning arm 13 drives the second tank body 18 to first move to the right from the position directly below the first tank body 17 by a preset distance (to avoid collision with the first tank body 17), and then to be lifted upward with the continuous rotation of the overturning arm, until the axis of the second tank body 18 is kept on the same horizontal plane as the axis of the first tank body 17, at this time the second tank body 18 is located to the right of the first tank body 17, the overturning and shifting is completed, and the second hydraulic cylinder 19 remains in the extension and retraction state, locking the overturning position.

[0022] Precise docking stage: start two pairs of first sliding rails 15 to control the sliders of the upper and lower sliding rails to synchronously move to the middle along the guide rails: the first sliding rail 15 on the upper side drives the first tank body 17 to move to the right, and the first sliding rail 15 on the lower side drives the second tank body 18 to move to the left; until the right end flange of the first tank body 17 and the left end flange of the second tank body 18 completely fit, and the sealing of the two tank bodies is realized through the preset sealing element (such as a sealing ring), forming the combined tank body structure of the "first tank body 17 and the second tank body 18", and lengthening the effective processing length of the hot pressing tank; After the docking is completed, the slider position of the first sliding rail 15 is locked to ensure that the docking state of the two tank bodies is stable, at this time the docking structure 1 can form a complete super-long workpiece processing cavity in cooperation with the end structure 3.

[0023] If only the medium length workpiece needs to be processed, the second tank body 18 does not need to be started, and the second tank body 18 is directly kept in the storage state directly below the first tank body 17, and the processing can be realized by the butt joint of the first tank body 17 and the end structure 3, which simplifies the operation process.

[0024] As shown in Figure 6 and Figure 7 As a preferred solution, further, the end structure 3 includes a pair of second sliding rails 31, a second bearing seat 32, a third tank body 33, a butt joint seat 34 and a heating assembly 35; one end of the pair of second sliding rails 31 is respectively and symmetrically arranged in the mounting groove 4 at the right end of the mounting box 6, the second bearing seat 32 is fixedly arranged between the second sliding rails 31, and the second bearing seat 32 moves left and right through the second sliding rails 31, the third tank body 33 is the same as the first tank body 17, the third tank body 33 is fixedly arranged on the second bearing seat 32, and the left end of the third tank body 33 can be butted with the right end of the first tank body 17, one end of the butt joint seat 34 is fixedly sleeved on the right end of the third tank body 33, and the right side wall of the butt joint seat 34 is circumferentially provided with a rotating groove, and the heating assembly 35 is detachably arranged on the right end of the third tank body 33; the second bearing seat 32 is driven by the second sliding rails 31 to move left and right, and the third tank body 33 is butted with the first tank body 17 or the second tank body 18, and the heating assembly 35 is carried by the butt joint seat 34 and moves in butt joint.

[0025] More specifically, the end structure 3 realizes flexible adaptation with the butt joint structure 1 through the second sliding rails 31, guarantees heating uniformity and maintenance convenience through the detachable heating assembly 35 and the sealing rotating seat 353, effectively solves the defects of “butt joint fixed” and “difficult to maintain the heating assembly 35” of the traditional hot pressing tank, and cooperates with the butt joint structure 1 to realize the core function of the multi-fan hot pressing tank.

[0026] As shown in Figure 6 and Figure 7As shown, as a preferred solution, further, the heating assembly 35 comprises a motor 351, a pulley 352, a rotating seat 353, a belt 354, four fans 355, a heating seat 356 and a heater body 357; the motor 351 is fixedly arranged on the upper wall of the docking seat 34, the pulley 352 is fixedly arranged on the driving end of the motor 351, the rotating seat 353 is circular, and the left and right side walls of the rotating seat 353 are both provided with outwardly convex annular rings, one end of the rotating seat 353 is movably inserted into the adapter groove of the docking seat 34 through the annular ring on the left side wall, and a sleeve groove is arranged on the outer side wall of the rotating seat 353, a plurality of through air vents 5 are arranged on the left side wall of the rotating seat 353, and the air vents 5 correspond to the interlayers between the sleeve wall 9 and the first tank body 17, the two ends of the belt 354 are movably sleeved on the pulley 352 and the sleeve groove of the rotating seat 353, respectively, one of the four fans 355 is fixedly penetrated in the middle of the rotating seat 353, and the other three fans 355 are equidistantly arranged on the outside of the one fan 355, the heating seat 356 is in a cylindrical structure, and the left side wall of the heating seat 356 is provided with the same adapter groove, the heating seat 356 is detachably arranged on the right side of the docking seat 34 and movably sleeved on the right end of the rotating seat 353, the heating seat 356 is relatively connected with the docking seat 34 through the two pairs of connecting rods 7, and the connecting rods 7 are fixed between the docking seat 34 and the heating seat 356 through the threaded nuts 8, the connecting rods 7 are located outside the rotating seat 353, and the heater body 357 is fixedly arranged in the heating seat 356; through the start of the motor 351, the rotating seat 353 is driven to rotate on the docking seat 34 by the pulley 352 and the belt 354, and the rotating seat 353 keeps docking with the docking seat 34 and the heating seat 356 during rotation, so as to adjust the blowing position of the fan 355, improve the uniformity of the air pressure and heat in the first tank body 17, and through the arrangement of the air vents 5 corresponding to the interlayers between the sleeve wall 9 and the first tank body 17 and the shielding fit of the rotating seat 353, when the fan 355 is started, the high-temperature air in the heating seat 356 is extracted through the air vents 5 and heated by the heater body 357, and then blown into the heating seat 356 from the fan 355 to form a circulation.

[0027] Power transmission starts when the hot pressing tank completes the docking and sealing of the tank body, the driving end of the motor 351 drives the pulley 352 to rotate synchronously; because the two ends of the belt 354 are movably sleeved on the sleeve groove of the pulley 352 and the rotating seat 353, respectively, the rotation of the pulley 352 is transmitted to the rotating seat 353 through the belt 354, and the rotating seat 353 is driven to reciprocate between the docking seat 34 and the heating seat 356 around its own axis (the motor 351 can realize the reciprocating motion of the rotating seat 353 through forward and reverse rotation control).

[0028] The heating and air flow generation are started synchronously. The heater body 357 generates high temperature after being powered on, rapidly heating the air in the heating seat 356; at this time, the four fans 355 rotate synchronously with the rotating seat 353 and are started, the fan 355 generates negative pressure to suck the high-temperature air in the heating seat 356 from the right side, and after being pressurized by the fan 355, the high-temperature air is transported to the left side to form directional high-temperature air flow.

[0029] The high-temperature air flow delivered by the air flow directional delivery and circulating fan 355 directly enters the interlayer formed by the inner wall sleeve 9 of the left wall of the rotating seat 353 through the air vent 5; since the air vent 5 is completely corresponding to the interlayer, and the rotating seat 353 always keeps the relative position of the air vent 5 and the interlayer during the rotation process (only the air supply angle of the fan 355 changes), the high-temperature air flow is evenly distributed in the entire inner part of the tank along the interlayer to heat the workpieces in the tank; at the same time, the low-temperature air flow in the tank flows back to the air vent 5 of the rotating seat 353 from the other end of the interlayer under the negative pressure action of the fan 355, and is again sucked into the fan 355 and heated by the heater main body 357, forming a closed-loop air flow circulation of “heating, delivery, backflow and reheating”, ensuring the uniformity of the temperature in the tank.

[0030] The reciprocating rotation of the rotating seat 353 drives the four fans 355 to change the air supply angle synchronously, avoiding the problem of “local air flow concentration” caused by the traditional fixed air supply; the equal-angle distribution of the three outer fans 355 and the synergistic effect of the center fan 355 can cover the entire cross section of the interlayer of the tank body, ensuring that there is no dead angle of air flow; in addition, the penetration design of the air vent 5 and the rotation shielding cooperation of the rotating seat 353 can adjust the rate of air flow entering the interlayer, further optimizing the temperature distribution.

[0031] As a preferred solution, further, the rotating seat 353 is started by the motor 351, and is driven by the belt 354 to reciprocating rotate between the docking seat 34 and the heating seat 356, for design, improving the uniformity of the air supply heating of the fan 355, the third tank body 33 can be opposite to the right end of the second tank body 18, for design, can increase the length of the equipment.

[0032] As a preferred solution, further, the second tank body 18 is started by the extension of the second hydraulic cylinder 19, drives the first overturning arm 12 and the second overturning arm 13 to overturn, promotes the second tank body 18 to be lifted to the right side of the first tank body 17 and to be on the same horizontal plane as the first tank body 17, its design overturning linkage process can drive the first tank body 17 to move to the right to be opposite to the second tank body 18, for design, opposite.

[0033] The detailed connection means is a well-known technology in the art, and the working principle and process are mainly introduced below. The specific work is as follows.

[0034] The installation box 6 is embedded in the ground as a whole, and the concave structure provides support and space for the docking structure 1. The second sliding rail 31 is pre-installed in the right-end mounting groove 4. The first tank body 17 is fixed to the upper left end of the mounting box 6 through one of the first bearing seats 16, and the second tank body 18 is located directly below the first tank body 17 through the other first bearing seat 16 (up and down staggered distribution); the first hydraulic cylinder 10 is in a retracted state, the second hydraulic cylinder 19 is in a retracted state, and the turnover arm assembly maintains an initial vertical posture; the door body 20 is in an open state, facilitating the placement of workpieces; The third tank body 33 is fixed to the second sliding rail 31 through the second bearing seat 32, and is initially located at the right end of the mounting box 6; the heater body 357 is supported by the heating seat 356, the heating seat 356 is fixed to the right side of the docking seat 34 through the connecting rod 7 and the nut 8, and the rotating seat 353 is movably arranged between the docking seat 34 and the heating seat 356, and the rotating seat 353, the fan 355 and the heater body 357 are in a standby state; The docking structure 1 can flexibly select “single tank body docking” or “double tank body combined docking” according to the length of the workpiece, and the specific process is as follows: Case 1: Only the first tank body 17 and the third tank body 33 are docked, which is suitable for medium-length workpieces, and the second tank body 18 does not need to be started, directly entering the docking link of the terminal structure 3; Case 2: The first tank body 17 and the second tank body 18 are combined, which is suitable for super-long workpieces; Through “height adjustment, turnover conversion and precise docking”, the two tank bodies are combined: That is, two pairs of first hydraulic cylinders 10 are started, driving the mounting seat 11, the turnover arm assembly and the first bearing seat 16 to move up and down by a certain distance, adjusting the overall height of the first tank body 17 and the second tank body 18, to avoid interference with the mounting box 6 or the ground during turnover; At the same time, one pair of second hydraulic cylinders 19 is started, and the extension end thereof is synchronously elongated, pushing the V-shaped first turnover arm 12 movably connected thereto to rotate around the mounting seat 11: since the two first turnover arms 12 are reversely and symmetrically arranged, the first turnover arm 12 drives the first tank body 17 to be slightly lifted upward and moved to the left, reserving space for right-side docking; At the same time, the first turnover arm 12 drives the second turnover arm 13 to be synchronously turned over, and during the turnover, the lower docking plate 14 and the second tank body 18 are synchronously moved: the second tank body 18 first moves to the right from the position directly below the first tank body 17 by a preset distance to avoid collision, and then continues to rotate upward with the turnover arm until the axis of the second tank body 18 is in the same horizontal plane as the axis of the first tank body 17, at which time the second tank body 18 is located to the right of the first tank body 17;
