As shown in fig. 1, 7 and 8, the lifting jig frame 6 is arranged at the lower side of the main shaft 5, can adopt a floor type design, has a lifting function, and is mainly used for providing support for the formed reinforcement cage; after the reinforcement cage is welded and formed along the inner die, the reinforcement cage is supported by the lifting jig frame 6, and the reinforcement cage can be separated from the inner die assembly 2 by adjusting the position of the stay bar 201, so that the demolding is realized; the lifting jig frame 6 can provide power required by lifting by a common power device such as an electric device, an oil cylinder and an air cylinder; in order to facilitate the reinforcement cage to move backwards under the support of the lifting jig frame 6, so that the reinforcement cage can be taken out from the rear end of the main shaft 5 after being molded, the lifting jig frame 6 is provided with a conveying mechanism 601, and the conveying mechanism 601 can be a conveying belt or a conveying roller.
As shown in fig. 1, 6, 7 and 8, the first support assembly 7 is used for providing support for the shaft sleeve 1, and indirectly providing support for the front end of the main shaft 5, so that the main shaft 5 always keeps a state of being horizontal; the first supporting assembly 7 comprises a lifting frame 701 and a wheel set 703, the lifting frame 701 is located at the lower side of the shaft sleeve 1 and is fixedly connected with the lifting frame 701, the wheel set 703 is formed by a plurality of roller sets 703 with parallel wheel shafts, the wheel set 703 is fixed at the lower end of the lifting frame 701, the wheel set 703 can be adjusted up and down based on the lifting frame 701, the wheel set 703 and the lifting tire frame 6 are propped against each other to provide support for the shaft sleeve 1 through the lifting frame 701, so that the main shaft 5 is kept in a horizontal state, a steel bar cage can move backwards along the lifting tire frame 6 and can pass through the outside of the first supporting assembly 7 and finally move out of the rear end of the main shaft 5, and in the process that the steel bar cage passes through the first supporting assembly 7, the wheel set 703 rolls on the inner side of the steel bar cage to provide support for the shaft sleeve 1.

As shown in fig. 1 and 6, in the foregoing forming apparatus, the lifting frame 701 in the first supporting assembly 7 has a lifting function, so that power is required to support, and a common power device such as an electric device, an oil cylinder, and an air cylinder may be disposed in the lifting frame 701 to drive the lifting frame, while, at the same time, since the steel reinforcement cage needs to pass through the first supporting assembly 7 to be removed from the rear end of the main shaft 5 after forming, the first supporting assembly 7 and its related components are required to be unable to form an obstacle to the removal of the steel reinforcement cage, so that the power device for driving the lifting frame 701 cannot be directly connected with an external pressure supply line or power supply line in a conventional manner, and therefore, in a specific implementation, the pressure supply line or power supply line may be disposed in the main shaft 5, and a rotary coupling member is disposed between rotary fittings such as the main shaft 5 and the sleeve 1, so that the pressure supply line or the power supply line is kept in communication during the relative rotation of the parts such as the main shaft 5 and the sleeve 1.
Referring to fig. 4 and 5, in the inner mold assembly 2, the adjustable supporting mechanism 202 is used to provide support for the supporting rod 201 and adjust the position of the supporting rod 201, and based on the above-mentioned arrangement of the adjustable supporting mechanism 202, various implementation structures may be selected, for example, the adjustable supporting mechanism 202 may be implemented based on a common structure such as a telescopic mechanism and a sliding mechanism, so as to obtain better stability and economy, in this embodiment, the adjustable supporting mechanism 202 adopts the following structure:
as shown in fig. 9 and 10, the adjustable supporting mechanism 202 includes a plurality of supporting links 203, a plurality of positioning links 204, and at least one traction sleeve 205; the stay bar 201 is connected with the main shaft 5 through a plurality of mutually parallel support connecting rods 203 to jointly form a parallel connecting rod mechanism, so that the stay bar 201 and the main shaft 5 can be far away from and close to each other, but the extending directions of the stay bar and the main shaft 5 are always kept parallel; the traction sleeve 205 is sleeved on the main shaft 5 and can slide along the main shaft 5, and the stay bar 201 is connected with the traction sleeve 205 through the positioning connecting rod 204; based on the design, the axial position of the traction sleeve 205 on the main shaft 5 is adjusted, and all the supporting rods 201 synchronously move under the limit action of the corresponding supporting connecting rods 203, namely synchronously move away from or approach to the main shaft 5, so that the position of the supporting rods 201 is uniformly adjusted, namely the purpose of adjusting the size of the internal mold is realized;
further, referring to fig. 2, 10 and 11, when the adjustable supporting mechanism 202 adopts the above design, the size of the inner mold can be adjusted by adjusting the axial position of the traction sleeve 205, and the position adjustment of the traction sleeve 205 is very easy to realize automatic control, so that the traction sleeve 205 is provided with a corresponding feeding device 8, and the working state of the feeding device 8 is regulated and controlled by the control system 4, thereby realizing automatic adjustment of the inner mold assembly 2, which can be implemented by adopting the following structure:
the inside of the main shaft 5 is hollow, a traction rod 9 extending along the axial direction of the main shaft is arranged in the main shaft, the rear end of the traction rod 9 extends from the rear end of the main shaft 5 and is in transmission connection with a feeding device 8, the feeding device 8 can adjust the axial movement of the traction rod 9 based on the control of the control system 4, and the feeding device 8 can be a screw mechanism, a cylinder, an oil cylinder and other conventional devices; the main shaft 5 is provided with a guide groove 206, and the traction sleeve 205 is connected with the traction rod 9 through a linkage piece 207 penetrating through the guide groove 206, so that the traction sleeve 205 and the traction rod 9 synchronously move; therefore, under the regulation and control of the control system 4, the feeding device 8 can drive the traction rod 9 to move so as to adjust the axial positions of all the traction sleeves 205, thereby achieving the purpose of automatically adjusting the internal mold; in addition, in the above structure, the traction sleeve 205 and the main shaft 5 cannot rotate relatively, while the feeding device 8 is more suitable to be arranged in the equipment and does not rotate along with the main shaft 5, and based on the situation, the traction rod 9 and the linkage 207 or the feeding device 8 can be connected by adopting a transmission mode of rotary fit, so as to solve the problem;
in the design, as the main shaft 5 adopts a hollow structure, the dead weight of the main shaft 5 is reduced to a certain extent; the traction rod 9 for driving the traction sleeve 205 is arranged inside the main shaft 5, so that the external space of the main shaft 5 is not occupied, and the matching of related components is more compact; meanwhile, since the traction rod 9 extending along the main shaft 5 is used for adjusting the position of the traction sleeve 205, all traction sleeves 205 on the main shaft 5 can be synchronously adjusted together, and a driving device is not required to be arranged for each traction sleeve 205 independently.
As shown in fig. 1, the forming equipment further comprises a casing 3 with a protective function, wherein the casing 3 covers the rear end of the main shaft 5 and other connecting parts, thereby improving the operation safety and the equipment operation stability in the manufacturing process of the reinforcement cage.
Meanwhile, the embodiment discloses a method for manufacturing a reinforcement cage based on the molding equipment, which comprises the following specific manufacturing steps:
1) Internal mold is adjusted
Referring to fig. 4 and 5, the positions of all the supporting rods 201 are adjusted according to the inner diameter size of the reinforcement cage to be manufactured, the distances between all the supporting rods 201 and the main shaft 5 are equal, and all the supporting rods 201 are distributed around the main shaft 5 in radial equiangular manner, so that the reinforcement cage is used as an inner mold for manufacturing the reinforcement cage;
2) Welded reinforcement cage
Referring to fig. 7, the main reinforcement 13, the stiffening stirrup 12 and the spiral stirrup 14 are arranged and welded on the outer side of the inner mold, and in the manufacturing process of the reinforcement cage, the driving system 11 is used for driving the main shaft 5 to rotate so as to realize station adjustment and spiral reinforcement winding;
3) Demoulding of reinforcement cage
Referring to fig. 5 and 8, the lifting jig frame 6 and the wheel group 703 are adjusted to move upwards synchronously until the lifting jig frame 6 provides sufficient support for the reinforcement cage, and the position of the supporting rod 201 is adjusted to reduce the distance between the supporting rod and the main shaft 5, namely, the reinforcement cage is separated from the inner mold; the lifting jig frame 6 and the wheel group 703 are kept synchronous in the process of moving upwards, so that the position of the main shaft 5 is not changed in the process;
4) Reinforcement cage for moving out
Referring to fig. 8, the cage is drawn back along the lifting jig 6 so that it passes out of the first support assembly 7 and is eventually removed from the rear end of the main shaft 5.
Referring to fig. 8, when the reinforcement cage is manufactured by the above method, the wheel set 703 of the first support assembly 7 initially abuts against the upper side of the lifting jig frame 6, but when the reinforcement cage is taken out through the first support assembly 7, the wheel set 703 of the first support assembly 7 abuts against the inner side of the reinforcement cage, so that the rear end of the spindle 5 is lifted upwards, but the lifting amount is smaller (almost equal to the thickness of the reinforcement cage), and the spindle 5 is longer in size, so that the corresponding movement amount generated at the rear end of the spindle 5 is very little, even negligible, and the cooperation stability of the rear end of the spindle 5 and other components is not substantially affected;
