Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

The first embodiment is as follows:

the invention is used for forming and processing the pipe-shaped seamless pipe. The workpiece 00 to be processed is a tubular seamless pipe.

As shown in fig. 1 to 6, a machining rapid prototyping apparatus provided by an embodiment of the present invention includes a frame 31, a lifting device, and a prototyping device:

the lifting device is fixedly arranged on the frame 31;

the lifting device can be a hydraulic cylinder, an air cylinder or an electric telescopic rod 50 and the like which can drive the upper die holder 11 to move up and down; the upper die base 11 is provided with a first molding cavity, the lower die base 10 is provided with a second molding cavity, and the first molding cavity is matched with the second molding cavity to form a complete molding cavity; the first molding cavity and the second molding cavity are both of incomplete hemispherical structures, and the molding cavity is of a spherical structure with notches at two ends. As shown in fig. 4, the lattice blocking portions 111 extend from two sides of the first molding cavity and/or the molding cavity in opposite directions, and are used for limiting the workpiece 00. The overall structure of the spherical space is approximately similar to that of a completely-intended spherical space, two parallel planes are adopted for cutting at two opposite sides of the spherical space, the two planes are symmetrically arranged along the center of the sphere, and the grid blocking parts 111 are oppositely arranged at the cutting positions in an extending mode. The check parts 111 extending in opposite directions can effectively position the workpiece 00, conveniently position the workpiece 00, and prevent the workpiece 00 from being uncontrollably shifted in the forming process.

The forming device is arranged on the frame 31 and used for extruding the workpiece 00 so as to enable the workpiece 00 to be attached to the side wall of the forming chamber.

Specifically, the forming device includes a driving motor 30, a supporting base 40, a driving device and an electric telescopic rod 50:

as shown in fig. 4, the driving motor 30 is fixedly disposed on the frame 31 and located at the same side of the upper die holder 11 and the lower die holder 10;

the supporting seat 40 is located between the upper die holder 11 and the lower die holder 10 and in the forming cavity, the supporting seat 40 is fixedly installed at the output end of the driving motor 30, an even number of driving chutes 401 are formed in the supporting seat 40, and two driving chutes 401 are taken as an example in the embodiment; when the driving motor 30 rotates, the supporting seat 40 is driven to rotate by the transmission shaft 33.

The driving device comprises a fixed gear 32 and formers which correspond to the driving chutes 401 one by one; the former comprises a transmission gear 34 and a reciprocating screw 35, the reciprocating screw 35 is rotatably arranged on the supporting seat 40, one end of the reciprocating screw 35 penetrates through the driving chute 401, the other end of the reciprocating screw is in transmission connection with the transmission gear 34, and the transmission gear 34 is meshed with the fixed gear 32; the fixed gear 32 and the rotation center of the support seat 40 are coaxially arranged, and the fixed gear 32 is fixedly arranged on the rack 31;

the electric telescopic rod 50 is provided with a sliding block, the sliding block is provided with a threaded hole matched with the reciprocating screw 35, the sliding block is slidably arranged in the driving sliding groove 401, the driving sliding groove 401 limits the rotational freedom degree of the sliding block, and when the reciprocating screw 35 rotates, the sliding block does not have the rotational freedom degree, so the sliding block can slide in a reciprocating manner along the extending direction of the driving sliding groove 401 under the driving of the reciprocating screw 35; the output end of the electric telescopic rod 50 is provided with a forming ball 51.

Specifically, the output end of the electric telescopic rod 50 is provided with a ball seat, and the forming ball 51 is rotatably arranged in the ball seat.

When the forming device works, a workpiece 00 is placed in the second forming cavity of the lower die holder 10, the forming device is located in the inner cavity of the workpiece 00, and then the lifting cylinder 20 is started to drive the upper die holder 11 to move downwards, so that the upper die holder 11 and the lower die holder 10 are matched to form a complete forming cavity.

The driving motor 30 is started to rotate to drive the supporting seat 40 to rotate, when the supporting seat 40 rotates, the reciprocating screw 35 is driven to further drive the transmission gear 34 to revolve along the fixed gear 32, when the transmission gear 34 revolves, the transmission gear 34 can also rotate due to the meshing of the transmission gear 34 and the fixed gear 32, when the transmission gear 34 rotates, the reciprocating screw 35 is driven to rotate to further drive the sliding block to slide in a reciprocating mode, and when the sliding block slides in a reciprocating mode, the electric telescopic rod 50 is driven to synchronously slide in a reciprocating mode. Under the control of the external control device, the electric telescopic rod 50 drives the forming ball 51 to move, and the forming ball 51 is abutted against the workpiece 00 to force the workpiece 00 to deform, so that the electric telescopic rod gradually clings to the inner wall of the forming cavity to form a structure similar to the forming cavity.

Example two:

in the first embodiment, since the forming process is gradual, and for materials with different thicknesses and materials, the feeding amount that should be given in the forming process is realized by the elongation of the electric telescopic rod 50, but when the workpiece 00 is thin-walled and the material is soft, the same feeding amount is adopted, which may cause the state shown in fig. 9, so that the workpiece 00 may be bent greatly, so that feeding of the electric telescopic rod 50 in the extending direction along the driving chute 401 may generate an abrupt force, and the resistance is increased, which may cause uncontrolled lifting of the equipment load, and easily cause damage to the equipment, in this embodiment, the apparatus further includes a control device, which includes a processor and a wireless transceiver module, the wireless transceiver module is fixedly disposed on the electric telescopic rod 50, and the driving motor 30, the electric telescopic rod 50, and the wireless transceiver module are all signal-connected to the processor, and the wireless transceiver module is signal-connected to the electric telescopic rod 50.

Further, the control device comprises a pressure sensor arranged on the ball seat for monitoring the pressure to which the forming ball 51 is subjected.

In operation, the pressure sensor monitors the pressure to which the forming ball 51 is subjected. When the state shown in fig. 9 is generated, the resistance applied to the forming ball 51 is suddenly increased, and at this time, the processor sends a control signal to the wireless transceiver module, and the wireless transceiver module transmits the signal to the electric telescopic rod 50 to control the electric telescopic rod 50 to retract a preset distance, so as to continue the forming process. When the state shown in fig. 9 occurs, because the deformation amplitude of the workpiece 00 is large, an included angle is formed between the side walls on both sides, at this time, the forming ball 51 continues to move along the original track to inevitably bear a large load, and when the electric telescopic rod 50 retracts by a distance of one end, and then continues to move, the inflection point of the deformation position of the workpiece 00 is avoided, after the electric telescopic rod 50 continues to move by the preset distance, the processor sends a signal again to control the electric telescopic rod 50 to return to the distance before retraction, and at this time, the resistance of the forming ball 51 is smaller than the resistance at the inflection point. The above actions are carried out in a circulating mode, and the problem of accelerated damage of equipment caused by the change of uncontrolled resistance can be effectively avoided.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
