According to the invention, the parallel frame in the shrinkage forging auxiliary frame equipment moves back and forth through the hydraulic cylinder so as to feed the aluminum alloy raw material, the C-shaped connecting frame and the driving rack on the side wall of the loading frame in the feeding process generate relative displacement to drive the one-way gear to rotate, so that the electrified vortex induction coil is indirectly used for heating the aluminum alloy material, and the forged aluminum alloy product is conveyed out of the equipment through pushing of the hydraulic cylinder, so that the phenomenon of surface scratch of the aluminum alloy product caused by multiple times of conveying, hoisting and fixing in the aluminum alloy material heating forging process is effectively avoided.

As a further scheme of the invention, the loading frame is provided with control long circular holes, two control long circular holes are respectively sleeved with a trigger long circular block, the two trigger long circular blocks are vertically and slidably connected in sliding holes formed in the C-shaped connecting frame, one end of each of the two control long circular holes is provided with a long through hole, two long through holes are respectively sleeved with a trigger rod, the lower ends of the two trigger rods are respectively and vertically and slidably connected with a pushing frame, the upper end surfaces of the two pushing frames are respectively and slidably connected with the lower end surface of the loading frame, the side walls of the two trigger rods are respectively and fixedly connected with a down rod, the two down rods are respectively and slidably connected in a downward inclined sliding groove formed in the inner wall of the long through hole, the side walls of the two pushing frames are provided with blanking long circular grooves, the side walls of two table legs close to the pushing frames are provided with blanking long circular grooves, and the inner walls of the blanking long circular grooves on the same side are sleeved with an X discharging rod, four vertexes of the X discharging rod are sleeved on the inner walls of the two long discharging circular grooves at the same side through a support, the middle of the X discharging rod is hinged, two discharging rods are arranged at the upper end of the X discharging rod, one end, penetrating through the long discharging circular groove, of the discharging rod at the front upper end is arranged in the long circular groove formed in the side wall of the discharging plate in a sliding mode, one end, penetrating through the other long discharging circular groove, of the discharging rod at the rear upper end is fixedly arranged in a long circular hole formed in the side wall of the discharging plate, and an avoidance long circular hole is formed in the rear end of the C-shaped connecting frame;

according to the automatic discharging cooling device, high-temperature aluminum alloy products are immediately pushed out after forging, manual fixing and hoisting are needed when discharging is carried out, due to the fact that the sizes of the aluminum alloy products are different, the situation that workers are scalded when oversize products are transported can occur, cooling is needed, a large amount of time is wasted, and the problem of low working efficiency is caused; when the invention works, when the C-shaped connecting frame is pushed by the hydraulic cylinder to move forwards during unloading, the triggering long round block falls into the control long round hole under the action of self gravity and slides forwards along with the C-shaped connecting frame, when the triggering long round block touches the triggering rod, the triggering rod is pushed to slide forwards along the long through hole and simultaneously drives the pushing frame below to move forwards, the pushing frame pushes two points at the rear end of the X discharging rod to move forwards while moving forwards (as shown in figures 10 and 11), at the moment, the angle between the upper end and the lower end of the X discharging rod is reduced, so that the two points at the upper end of the X discharging rod are lifted, the triggering long round block continues to push the triggering rod to move forwards along with the continuous movement of the C-shaped connecting frame, and when the triggering rod moves forwards, the triggering rod is subjected to the sliding action of the descending rod on the side wall along the inclined downwards sliding chute, so that the triggering rod moves downwards and slides into the pushing frame, the upper end of the X discharging rod continuously rises to lift the discharging plate (as shown in figure 10, the rear upper end of the X discharging rod is fixed with the discharging plate, the fixed point of the front upper end is arranged on a long circular groove formed in the side wall of the discharging plate in a sliding mode, so that the horizontal movement speed of the discharging plate is the same as the horizontal movement speed of the C-shaped connecting frame, the synchronous effect is achieved, and the phenomenon that the aluminum alloy products are scratched due to the fact that the speeds of the discharging plate and the aluminum alloy products are different is avoided, two contact points of the discharging plate and the upper end of the X discharging rod are located at the lower end of the discharging plate, so that the upper end of the discharging plate can exceed the upper end face of the loading frame, when the trigger rod moves to the foremost end of the long through hole, the trigger rod also moves downwards to the bottom end of the control long through hole, at the moment, the upper end of the X discharging rod is located at the highest position, the discharging plate lifts the aluminum alloy products to enable clamp points of the aluminum alloy products to be separated from the clamp rod, the front end of the long round block slides over the upper end of the trigger rod and then moves forwards continuously along with the forward movement of the C-shaped connecting frame, the stripper plate automatically sinks under the gravity of the aluminum alloy product, the stripper plate moves downwards while the C-shaped connecting frame also moves forwards, the trigger rod is separated from the action of the trigger long round block, the angle between the upper end and the lower end of the X-shaped stripper rod is increased along with the downward movement of the stripper plate, the trigger rod moves backwards and moves upwards along the long through hole, finally the stripper plate moves to the lowest end, the trigger rod is positioned at the rearmost end of the long through hole (as shown in figure 10, the process is opposite to the beginning and is not described herein), the unloading is finished, when the material is fed again, the hydraulic cylinder shrinks, the C-shaped connecting frame indirectly moves backwards, in the process of moving backwards, because the trigger long round block is provided with an inclined plane which is high at the back and low at the front, when the trigger long round block is contacted with the trigger rod, the trigger long round block gradually overcomes the gravity and gradually jacks up along the inclined plane, thereby not triggering any action of the trigger lever.

According to the invention, the trigger long round block with the inclined plane, which is vertically and slidably connected to the C-shaped connecting frame, pushes the trigger rod to move forwards when the trigger long round block moves forwards, so that the unloading plate is indirectly driven to move forwards while the horizontal moving speed of the trigger long round block is kept the same as that of the C-shaped connecting frame, the unloading is smoothly finished, the trigger long round block can automatically finish descending after the unloading is finished, the trigger long round block can be lifted under the action of the trigger rod when the C-shaped connecting frame returns, and thus other actions cannot be caused in the return stroke action, and the problem that the temperature of the just forged aluminum alloy material is too high and the operation is not good, and workers are possibly injured when the aluminum alloy material is unloaded is effectively solved.

As a further scheme of the invention, a plurality of limiting rods are vertically and slidably connected with the two discharging plates, the limiting rods penetrate through the lower ends of the discharging plates and are fixedly provided with return springs, and the other ends of the return springs are fixedly arranged at the lower ends of the discharging plates;

when the aluminum alloy product is unloaded, due to different shapes of the aluminum alloy product, the unloading plate is directly contacted with the aluminum alloy product during unloading, so that the aluminum alloy product can slide in the horizontal direction, and the risk of sliding can be caused; when the aluminum alloy discharging plate is used, when the discharging plate rises, the limiting rods firstly contact with an aluminum alloy product, the discharging plate continues to rise, the limiting rods move downwards by overcoming the tension of the return spring due to the fact that the centers and the shapes of the aluminum alloy are different, the downward moving strokes are different, and finally when the aluminum alloy product is completely contacted with the discharging plate, the extending positions of the limiting rods are different in length, so that the aluminum alloy product is fixed in the horizontal direction.

Because the centers of gravity and the shapes of the aluminum alloys are different, the aluminum alloy product is completely limited in the horizontal direction by enabling the independent limiting rods to extend out of the stripper plate in different lengths when the independent limiting rods are contacted with the lower end face of the aluminum alloy, and the phenomenon that the aluminum alloy product is damaged and destroyed due to falling is effectively solved.

As a further scheme of the invention, the upper end of the limiting rod is arranged to be spherical, so that the phenomenon of scratching the lower surface of an aluminum alloy product is effectively avoided.

As a further scheme of the invention, an auxiliary plate is sleeved at one end, penetrating through a long blanking circular groove, of two supports sleeved with the long blanking circular groove at the lower end of an X discharging rod, the supports are sleeved in auxiliary long circular holes formed in the side wall of the auxiliary plate, and the phenomenon that the X discharging rod is unnecessarily deformed in the moving process to cause equipment to be blocked is effectively avoided by adding a kinematic pair.

As a further scheme of the invention, the hydraulic cylinder adopts the synchronous oil cylinder, and the phenomenon that the C-shaped connecting frame and the loading frame are clamped in the moving process of the equipment is avoided by simultaneously working the two synchronous cylinders.

Compared with the prior art, the invention has the beneficial effects that:

1. according to the invention, the parallel frame in the shrinkage forging auxiliary frame equipment moves back and forth through the hydraulic cylinder so as to feed the aluminum alloy raw material, the C-shaped connecting frame and the driving rack on the side wall of the loading frame in the feeding process generate relative displacement to drive the one-way gear to rotate, so that the electrified vortex induction coil is indirectly used for heating the aluminum alloy material, and the forged aluminum alloy product is conveyed out of the equipment through pushing of the hydraulic cylinder, so that the phenomenon of surface scratch of the aluminum alloy product caused by multiple times of conveying, hoisting and fixing in the aluminum alloy material heating forging process is effectively avoided.

2. According to the invention, the trigger long round block with the inclined plane, which is vertically and slidably connected to the C-shaped connecting frame, pushes the trigger rod to move forwards when the trigger long round block moves forwards, so that the unloading plate is indirectly driven to move forwards while the horizontal moving speed of the trigger long round block is kept the same as that of the C-shaped connecting frame, the unloading is smoothly finished, the trigger long round block can automatically finish descending after the unloading is finished, the trigger long round block can be lifted under the action of the trigger rod when the C-shaped connecting frame returns, and thus other actions cannot be caused in the return stroke action, and the problem that the temperature of the just forged aluminum alloy material is too high and the operation is not good, and workers are possibly injured when the aluminum alloy material is unloaded is effectively solved.

3. Because the centers of gravity and the shapes of the aluminum alloys are different, the aluminum alloy product is completely limited in the horizontal direction by enabling the independent limiting rods to extend out of the stripper plate in different lengths when the independent limiting rods are contacted with the lower end face of the aluminum alloy, and the phenomenon that the aluminum alloy product is damaged and destroyed due to falling is effectively solved.

material is heated, then the die is started to forge, in the forging process, the aluminum alloy plate can generate the phenomenon of shrinkage deformation, under the condition that the distance between the two parallel frames 15 does not change, the compensation round rod 17 irregularly moves in the fine adjustment long circular groove 16, so as to compensate the deformation distance of the aluminum alloy section bar in the left-right direction, and simultaneously, the compensation round rod 17 and the compensation plate 18 also generate relative displacement transformation, so as to compensate the deformation of the aluminum alloy in the front-back direction (as shown in figures 6 and 8, the aluminum alloy raw material is designed with a clamp point at the beginning of forging, so as to avoid the deformation of the aluminum alloy in the vertical direction), and simultaneously, the fine adjustment plate 19 and the compensation long circular hole 20 also generate irregular displacement, so as to compensate the deformation displacement of the front end and the rear end (as shown in figures 5 and 6, the matching of the fine adjustment plate 19 and the compensation oblong hole 20 avoids that the deformation limit positions of the front end and the rear end exceed the limit positions of the compensation plate 18, and the length and the strength of the compensation plate 18 are limited by the vortex induction coil 25, so that the compensation plate 18 can be shorter and firmer; the blanking of the second process, after forging, raise the upper die, lower the die, start hydraulic cylinder 11 and push out the aluminium alloy that forges (the process of pushing out is opposite with the entering process, does not do this and does not need to be repeated here, and at this moment, the one-way gear 28 at both ends no longer drives lead screw 23 and rotates because of the one-way drive effect, avoids on vortex induction coil 25 is promoted the aluminium alloy product that has already been deformed, thereby avoids causing the phenomenon that the collision caused the equipment to damage to appear), and the circulation is reciprocal can.

according to the automatic discharging cooling device, high-temperature aluminum alloy products are immediately pushed out after forging, manual fixing and hoisting are needed when discharging is carried out, due to the fact that the sizes of the aluminum alloy products are different, the situation that workers are scalded when oversize products are transported can occur, cooling is needed, a large amount of time is wasted, and the problem of low working efficiency is caused; when the invention works, when in unloading, the triggering long round block 34 falls into the control long circular hole 33 under the action of self gravity to slide forwards along with the C-shaped connecting frame 22 when the C-shaped connecting frame 22 is pushed to move forwards by the hydraulic cylinder 11, when the triggering long round block 34 touches the triggering rod 36, the triggering rod 36 is pushed to slide forwards along the long through hole 35, the pushing frame 37 below is driven to move forwards, the pushing frame 37 pushes two points at the rear end of the X discharging rod 41 to move forwards while moving forwards (as shown in figures 10 and 11), at the moment, the angle between the upper end and the lower end of the X discharging rod 41 is reduced, so that the two points at the upper end of the X discharging rod 41 are lifted, as the C-shaped connecting frame 22 continues to move, the triggering long round block 34 continues to push the triggering rod 36 to move forwards, and at the same time of the triggering rod 36 is pushed by the descending rod 38 of the side wall to slide along the chute 39 which inclines downwards by the descending rod, the trigger rod 36 moves downwards to slide into the pushing frame 37, the upper end of the X discharging rod 41 continues to rise so as to lift the discharging plate 43 (as shown in fig. 10, the rear upper end of the X discharging rod 41 is fixed with the discharging plate 43, the fixing point of the front upper end is arranged in a long circular groove formed in the side wall of the discharging plate 43 in a sliding mode, so that the discharging plate 43 moves in the horizontal direction at the same speed as the horizontal moving speed of the C-shaped connecting frame 22, a synchronous effect is achieved, the phenomenon that the discharging plate 43 scratches an aluminum alloy product due to the fact that the aluminum alloy product is different in speed is avoided, two contact points of the upper ends of the discharging plate 43 and the X discharging rod 41 are located at the lower end of the discharging plate 43, so that the upper end of the discharging plate 43 can exceed the upper end face of the loading frame 12), when the trigger rod 36 moves to the foremost end of the long through hole 35, the trigger rod 36 also moves downwards to the bottom end of the control long through hole 33, and the upper end of the X discharging rod 41 is located at the highest position, the stripper plate 43 lifts the aluminum alloy product to separate the aluminum alloy product from the constraint of the clamp rod 21, the front end of the long round block 34 slides over the upper end of the trigger rod 36 to move forward continuously as the C-shaped connecting frame 22 moves forward continuously, the stripper plate 43 automatically sinks under the gravity of the aluminum alloy product at this time, the stripper plate 43 moves downward while the C-shaped connecting frame 22 moves forward, the trigger rod 36 separates from the action of the trigger long round block 34 at this time, the angle between the upper end and the lower end of the X-shaped stripper rod 41 is increased as the stripper plate 43 moves downward, the trigger rod 36 moves backward and upward along the long through hole 35, finally the stripper plate 43 moves to the lowest end, the trigger rod 36 is positioned at the rearmost end of the long through hole 35 (as shown in fig. 10, the process is opposite to the beginning, and is not described herein), at this time, the unloading is completed, when the hydraulic cylinder 11 contracts after the reloading, the C-shaped connecting frame 22 indirectly moves backward, in the process of moving backwards, as the triggering long round block 34 is provided with an inclined plane which is high at the back and low at the front, the triggering long round block 34 is gradually jacked up along the inclined plane by overcoming the gravity gradually through the triggering rod 36 when the triggering long round block 34 is contacted with the triggering rod 36, so that any action of the triggering rod 36 is not triggered.

According to the invention, the trigger long round block 34 with the inclined plane, which is vertically connected with the C-shaped connecting frame 22 in a sliding manner, pushes the trigger rod 36 to move forwards when moving forwards, so that the unloading plate 43 is indirectly driven to move forwards and the horizontal moving speed of the C-shaped connecting frame 22 is kept the same, the unloading is smoothly finished, the unloading can be automatically finished after the unloading is finished, the trigger long round block 34 can be lifted under the action of the trigger rod 36 when the C-shaped connecting frame 22 returns, so that other actions cannot be caused in the return stroke action, and the problems that the temperature of the just forged aluminum alloy material is too high and the operation is not good when the aluminum alloy material is unloaded, and workers are possibly injured are effectively solved.

when the aluminum alloy product is unloaded, due to different shapes of the aluminum alloy product, the unloading plate 43 is directly contacted with the aluminum alloy product during unloading, so that the aluminum alloy product can slide in the horizontal direction, and the risk of sliding can be caused; when the aluminum alloy discharging device is used, when the discharging plate 43 rises, the limiting rods 45 firstly contact with an aluminum alloy product, the discharging plate 43 continues to rise, the limiting rods 45 overcome the tension of the return spring 46 to move downwards due to different centers and shapes of aluminum alloy, the downward moving strokes are different, and finally when the aluminum alloy product completely contacts with the discharging plate 43, the extending lengths of the limiting rods 45 are different, so that the aluminum alloy product is fixed in the horizontal direction.

Because the centers of gravity and the shapes of the aluminum alloys are different, the aluminum alloy product is completely limited in the horizontal direction by enabling the independent limiting rods 45 to be different in length extending out of the discharging plate 43 when being contacted with the lower end face of the aluminum alloy, and the phenomenon that the aluminum alloy product is damaged and damaged due to falling is effectively solved.

As a further scheme of the invention, the upper end of the limiting rod 45 is arranged in a spherical shape, so that the phenomenon of scratching the lower surface of an aluminum alloy product is effectively avoided.

As a further scheme of the invention, the hydraulic cylinder 11 adopts a synchronous oil cylinder, and the phenomenon that the C-shaped connecting frame 22 and the loading frame 12 are blocked in the moving process of the equipment is avoided by simultaneously working the two synchronous cylinders 11.

The working principle is as follows: when the invention is used, the equipment is firstly assembled, the equipment is firmly fixed on an upper die bracket and a lower die bracket (as shown in figure 2, the position of a forging die and the position of an aluminum alloy raw material are roughly drawn in figure 2, the forging die is roughly divided into an upper part and a lower part, an equipment operation part is positioned under the die, before the aluminum alloy section enters into processing, a clamp point of the aluminum alloy section is designed firstly, so that the aluminum alloy section can be positioned and fixed by a clamp rod 21, and the redundant part is cut when the operation is finished, only one half of the equipment is shown in the figure, the forging part shares one clamp, the upper material part and the lower material part are designed to be mutually exclusive, and under the condition that half of feeding, half of forging, half of discharging is finished by forging, one end of feeding is forged again, the cycle reciprocating is finished, figure 2 is rotated ninety degrees anticlockwise, the left side and the right side of the equipment are shown in the upper side and the lower side of the figure, the left side and the right side of the drawing are the back and the front sides of the equipment, wherein the same side is specifically the left side or the right side); the use is divided into two processes, the feeding process is carried out, the hydraulic cylinder 11 is started to enable the hydraulic cylinder 11 to extend to push the parallel frame 15 to drive the C-shaped connecting frame 22 to move to the front end of the loading frame 12 along the front end, the peripheral clamp points of the aluminum profile plate are fixedly arranged on the outer side walls of the four clamp rods 21 (as shown in figure 4, the right rear side is overlooked in the middle, the rotary effect is ignored), the hydraulic cylinder 11 is started to contract again to enable the C-shaped connecting frame 22 to move backwards along the upper surface of the loading frame 12, the driving rack 30 on the front side wall of the loading frame 12 on the right side is meshed with the one-way gear 28 on the front end in the moving process, so that the one-way gear 28 on the front end rotates, the one-way gear 28 rotates to drive the lead screw 23 on the front end to rotate, the lead screw 23 rotates to drive the stepping block 24 to move towards the middle of the equipment along the axial direction of the lead screw 23 (as shown in figure 4, the synchronous wheel 26 on the left side of the lead screw 23 on the front end is also acted by the lead screw 23 to rotate, when the synchronous wheel 26 rotates, the synchronous belt 27 on the outer side is driven, the synchronous belt 27 rotates to drive the other synchronous wheel 26 at the left end of the screw 23 on the rear side to rotate, the synchronous wheel 26 at the rear end drives the screw 23 on the rear side to rotate, the rotating directions of the screw 23 on the front side and the rear side are the same, the one-way gear 28 at the end of the screw 23 on the right side at the rear end cannot be meshed with the driving rack 30 on the rear side, so that the one-way gear 28 at the rear end is in an idle state, when the two screws 23 rotate in the same direction, the rotating directions of the internal threads of the stepping blocks 24 on the left side and the right side are opposite, and the stepping blocks 24 on the left side and the right side synchronously move towards the middle of the screw 23), when the stepping blocks 24 move towards the middle, the vortex induction coils 25 are driven to move towards the middle, and when the two vortex induction coils 25 move to be in middle contact, the one-way gear 28 at the front end moves to the tail end of the driving rack 30, so that the one-way gear 28 is separated from the driving rack 30, at this time, the eddy induction coil 25 does not move towards the middle any more, at the moment when the one-way gear 28 and the driving rack 30 are separated, the eddy induction coil 25 is loaded with current, the one-way gear 28 at the rear end is meshed with the driving rack 30, the one-way gear 28 at the rear end drives the transmission 29 to start rotating, the transmission 29 rotates to enable the lead screw 23 connected with the transmission to start to rotate reversely and decelerate (as shown in fig. 2, the driving rack 30 at the front end is shorter than the driving rack 30 at the rear end, the rotating time of the one-way gear 28 at the rear end is longer, so that the moving speed of the eddy induction coil 25 is indirectly slowed down), the lead screw 23 rotates reversely and drives the stepping block 24 at the same side to start to move slowly towards the left side and the right side, at this time, the eddy induction coil 25 heats the aluminum alloy raw material (slowly), as the hydraulic cylinder 11 continues to shrink, the eddy induction coil 25 moves to the left side and the right side edges of the equipment, and departs from the forging area, when the vortex induction coil 25 moves to the edge, the aluminum alloy raw material is heated, then the die is started to forge, in the forging process, the aluminum alloy plate can generate the phenomenon of shrinkage

designed with a clamp point at the beginning of forging, so as to avoid the deformation of the aluminum alloy in the vertical direction), and simultaneously, the fine adjustment plate 19 and the compensation long circular hole 20 also generate irregular displacement, so as to compensate the deformation displacement of the front end and the rear end (as shown in figures 5 and 6, the matching of the fine adjustment plate 19 and the compensation oblong hole 20 avoids that the deformation limit positions of the front end and the rear end exceed the limit positions of the compensation plate 18, and the length and the strength of the compensation plate 18 are limited by the vortex induction coil 25, so that the compensation plate 18 can be shorter and firmer; the blanking of the second
