[0033] A driving mechanism 30 is located below the extrusion forming mechanism 20, is fixed on the frame body 10, has a transmission shaft 31 and a first driving assembly for driving the transmission shaft 31 to rotate relative to the frame body 10, and has a plurality of connecting portions 312 extending in a circumferential direction along one side of a main body portion 311 of the transmission shaft 31, a rotating assembly 3121 is sleeved on each connecting portion 312, each rotating assembly abuts against an outer circumferential surface of one of the forming blocks 21, and the transmission shaft 31 has a feeding channel 313 inside, and a top end of the feeding channel 313 is located at the discharge port 212.

[0035] In the embodiment, the plane extrusion forming device 01 is provided, the two rotating wheels 411 are arranged at the bottom end of the feeding channel 313 inside the transmission shaft 31, so that the block-shaped product is dropped on one of the rotating wheels 411 or between the two rotating wheels 411 after being moved out of the feeding channel 313, and then the block-shaped product is slowly fed on the conveying belt 42 through the rotating wheels 411 rotating towards each other, so that the generation of burrs or local falling of the block-shaped product at the edge position is avoided.

[0037] Further, a speed reduction ratio of the first gear and the second gear is 1:1.

[0039] In some embodiments, the angle between the two adjacent surfaces of the adjacent two forming blocks 21 is a distribution internal angle, and the straight line in the moving direction of the forming block 21 and the plane where any contact surface of the forming block 21 is located have an included angle.
[0040] In the embodiment, the extrusion forming mechanism 20 includes a plurality of forming blocks 21 distributed in a ring shape, the forming blocks 21 are triangular blocks, the adjacent two surfaces of the forming blocks 21 are in close contact in a triangular shape, the angle between the two adjacent surfaces is a distribution internal angle, each forming block 21 is limited to move in a straight line direction, and the straight line in the moving direction of the forming block 21 and the plane where any contact surface of the forming block 21 is located have an included angle. Those skilled in the art can understand that the straight line in the moving direction of the forming block 21 and the plane where any contact surface of the forming block 21 is located have an included angle, that is, the relationship between the straight line in the moving direction of the forming block 21 and the plane where any contact surface of the forming block 21 is located is not parallel. Therefore, the contact surfaces between the plurality of forming blocks 21 are inclined with respect to the moving direction, the pushing force of any forming block 21 on the contact surface of the adjacent forming block 21 can be converted into the pushing force in the moving direction, so that any forming block 21 moves and all the forming blocks 216 move synchronously.
[0041] In some embodiments, at least two of the forming blocks 21 are provided with return springs 213, and the directions of the return springs 213 are consistent with the moving directions of the corresponding forming blocks 21.
[0042] In the embodiment, those skilled in the art can understand that in actual industrial design, in general, the cost of the one-way force driving mechanism 30 is significantly lower than that of the two-way force driving mechanism 30, so the return spring 213 is generally used for return. In the application, considering the existence of the contact surface friction force, the use of a single return spring 213 may cause unstable return, and therefore the use of more than two return springs 213 can ensure smooth implementation. Generally, the plurality of return springs 213 are symmetrically arranged based on the distribution of the plurality of forming blocks 21.
[0043] In some embodiments, the extrusion forming mechanism 20 further comprises a baffle 22, a cover plate 23 and a lower bottom plate 24, the forming blocks 21 are clamped and limited in the distribution plane by the cover plate 23 and the lower bottom plate 24 respectively, the lower bottom plate 24 is fixed on the frame body 10, the baffle 22 is fixed on the lower bottom plate 24, and the baffle 22 is limited outside the forming blocks 21 along the moving direction of the forming blocks 21.
[0044] In the embodiment, the baffle 22 is fixed outside the forming blocks 21 along the moving direction of the forming blocks 21. It is easy to understand that the forming blocks 21 can be limited and moved in other ways such as guide rails, strip holes and strip grooves, but the baffle 22 is the most stable and has the largest stress limit.
[0045] In some embodiments, a lower sliding plate 25 is arranged below the plane where the forming blocks 21 are located and is installed in an extendable manner opposite the center point where the forming blocks 21 are distributed, the lower sliding plate 25 is clamped in the lower bottom plate 24, and a through hole 251 is further arranged on the lower sliding plate 25.
[0046] When the lower sliding plate 25 is located at the first position, the lower sliding plate 25 is located in the area where the center point where the forming blocks 21 are distributed, and the forming blocks 21 form the extrusion forming area 211.
[0047] When the lower sliding plate 25 is located at the second position, the through hole 251 of the lower sliding plate 25 is located in the area where the center point where the forming blocks 21 are distributed and is in communication with the discharge port 212.
[0048] In the embodiment, the forming blocks 21 are clamped and limited in the distribution plane by the cover plate 23 and the lower bottom plate 24 respectively, and the lower sliding plate 25 is arranged below the plane where the forming blocks 21 are located and is installed in an extendable manner opposite the center point where the forming blocks 21 are distributed. Because the lower bottom plate 24 is concave, the lower sliding plate 25 is clamped in the lower bottom plate 24. The application scenario of the present application is to extrude powdery materials into blocks, such as extruding tantalum powder into tantalum blocks, so that the lower sliding plate 25 plays a role of supporting the powdery materials and the blocks during the extrusion process, and on the other hand, based on the extension of the lower sliding plate 25, the blocks can be accurately dropped to complete the discharge after the blocks are formed.
[0049] In some embodiments, the rotating assembly 3121 has an eccentric shaft and a bearing, the bearing is sleeved on the eccentric shaft, both ends of the eccentric shaft are fixed on the connecting part 312 in the up-down direction, and the bearing abuts against the outer circumferential surface of one of the forming blocks 21.
[0050] In the present embodiment, since the contact surface friction of the forming blocks 21 is negligible in ideal conditions, the pushing process can ensure smooth implementation, but in practice, the contact surface friction of the plurality of forming blocks 21 can exceed the pushing force, at which time auxiliary mechanisms such as rollers 3251 can be added outside the forming blocks 21 to reduce the negative impact of the contact surface friction.
[0051] In some embodiments, the driving mechanism 30 also has a ball bearing, and the main body part 311 of the transmission shaft 31 is sleeved on the frame body 10 through the ball bearing. In the present embodiment, through the above-mentioned arrangement, the transmission shaft 31 can be rotatably arranged on the frame body 10, and then the main body part 311 of the transmission shaft 31 is fixed below the plurality of forming blocks 21, so that the plurality of connecting parts 312 of the transmission shaft 31 are arranged on the outer periphery of the extrusion forming mechanism 20, and then the bearings sleeved on each eccentric shaft are in contact with the outer periphery of one of the forming blocks 21. When the first driving assembly drives the transmission shaft 31 to rotate relative to the frame body 10, the plurality of connecting parts 312 of the transmission shaft 31 are forced to rotate relative to the axial direction of the transmission shaft 31, and then the bearings of the rotating assembly 3121 sleeved on the connecting parts 312 push the corresponding forming blocks 21 to move along the moving direction of the forming blocks 21, and then the plurality of forming blocks 21 are forced to converge to form an extrusion forming area 211, and the powder in the extrusion forming area 211 is extruded into a block-shaped object.
[0052] In some embodiments, the first driving assembly has a driving unit 321, a lead screw 322, a lead nut 323, a sliding block 324, and a connecting piece 325. The two ends of the lead screw 322 are rotatably mounted on the frame body 10. The output end of the driving unit 321 is in transmission connection with the input end of the lead screw 322. The lead nut 323 is threadedly mounted on the lead screw 322. A limiting unit is arranged on the frame body 10, and the limiting unit is used to limit the axial rotation of the lead nut 323. The sliding block 324 is fixed on the lead nut 323. A limiting groove 3241 is arranged on the end face of the sliding block 324 away from the side where the lead nut 323 is located. One end of the connecting piece 325 is fixed on the main body part 311 of the transmission shaft 31, and the other end of the connecting piece 325 is fixed with a roller 3251, and the roller 3251 is located in the limiting groove 3241.
[0053] In the present embodiment, the driving unit 321 can be a motor, and the motor drives the lead screw 322 to rotate, so that the lead nut 323 drives the sliding block 324 to move. Since the limiting unit is arranged on the frame body 10, the limiting unit can be a sliding rail, so that the sliding block 324 is sleeved on the sliding rail, and then the axial rotation of the lead nut 323 can be limited.
[0054] Further, the roller 3251 on the connecting piece 325 has a gap with the limiting slot 3241 on the sliding block 324, when the motor drives the screw rod 322 to rotate, the screw nut 323 drives the sliding block 324 to move along the axial direction of the screw rod 322, when the sliding block 324 moves, the side wall of the limiting slot 3241 is forced to contact and push the roller 3251 to move, since the end of the connecting piece 325 away from the roller 3251 is fixed on the main body part 311 of the transmission shaft 31, therefore, when the sliding block 324 drives the roller 3251 to move, the roller 3251 is forced to roll at the same time, further realizing that the connecting piece 325 drives the main body part 311 of the transmission shaft 31 to swing, so as to realize that the transmission shaft 31 is driven to rotate relative to the frame body 10.
[0055] In some embodiments, four forming blocks 21 are adopted, the distribution internal angle of the forming block 21 is a right angle, and the forming block 21 is used for extrusion forming processing of the tantalum block core; four reset springs 213 are symmetrically and parallelly distributed, the reset spring 213 is fixed between the spring guide rod and the spring seat, and the spring guide rod and the spring seat are respectively fixed to the forming block 21 and the cover plate 23; after the tantalum block core is processed, the lower sliding plate 25 is retracted, and then the tantalum block core is dropped to complete the discharging, and then the lower sliding plate 25 is extended, and the tantalum powder is added to start the extrusion forming processing in the next cycle.
[0056] Further, the tantalum block core is removed through the feeding channel 313 in the transmission shaft 31 and falls on one of the two wool wheels 411 or between the two wool wheels 411, and then the two wool wheels 411 are rotated towards each other to drive the block product to slowly enter the conveyor belt 42, so as to avoid the generation of burrs or local falling of the block at the edge position.
[0057] It is apparent for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be included in the present application.
