Referring again to fig. 5 and 6, more specifically, the driving member 402 includes an annular mounting plate 402a and a pressing block 402b; the annular mounting plate 402a is fixedly connected to the bottom plate 101, the diameter of the annular mounting plate 402a is larger than that of the annular turntable 102, and the annular mounting plate 402a and the annular turntable 102 are concentrically arranged; the extrusion blocks 402b are provided with a plurality of pieces, the circumferences of the extrusion blocks are equidistantly distributed on the inner ring surface of the annular mounting plate 402a, and each rotary rod 401b can be in extrusion fit with the extrusion block 402b so as to control the collision ball 401c to rotate by taking the torsion spring shaft as the rotation axis.
Referring to fig. 2, 5 and 6, in the implementation of the crash assembly 400, a crash piece 401 is disposed outside each lower die tube 104, during the rotation of the annular turntable 102, the annular turntable 102 can drive the crash piece 401 to be in press fit with the driving piece 402, that is, during the rotation of the annular turntable 102 at each angle, the rotating rod 401b can be in press fit with the pressing block 402b located on the rotating path of the annular turntable 102, during the process that the rotating rod 401b contacts the pressing block 402b, the rotating rod 401b can drive the crash ball 401c to rotate around the rotation axis of the torsion spring axis, and after the rotating rod 401b is separated from the pressing block 402b, the rotating rod 401b can be quickly reset through the torsion spring axis, and the crash ball 401c on the rotating rod 401b can be transformed from a lifted state to a reset state (the crash ball 401c is tightly attached to the surface of the annular turntable 102), and the crash ball 401c can hit the surface of the annular turntable 102 outside the lower die tube 104 during the reset process, and vibration is generated through the crash;
firstly, the annular rotary table 102 drives a lower die pipe 104 positioned below the blanking pipe 105, and in the process of moving out of the blanking pipe 105, the collision ball 401c intermittently knocks on the surface of the annular rotary table 102 outside the lower die pipe 104, so that powder raw materials in the lower die pipe 104 vibrate and are filled, meanwhile, the blanking pipe 105 is matched to continuously supplement the powder raw materials into the lower die pipe 104, so that the compaction of the powder raw materials in the lower die pipe 104 rotating outside the blanking pipe 105 is ensured, the product forming quality is improved, the automation degree is high, and automatic filling, strickling, vibration filling and filling after filling in the lower die pipe 104 are realized; secondly, after the powder raw material is stamped and formed, the side surface of the solid product is tightly attached to the inner wall of the lower die pipe 104, if a large friction force exists, the product cannot be naturally blanked when passing through the blanking port 200, so that automatic discharging cannot be formed, therefore, after the product in the lower die pipe 104 right below the upper die plate 103 is formed, the product continues to rotate clockwise through the annular rotary table 102, in the process, the rotary rod 401b is in extrusion fit with the extrusion block 402b, and the impact ball 401c intermittently knocks on the surface of the annular rotary table 102 outside the lower die pipe 104, so that the product in the lower die pipe 104 can be ensured to be separated from the lower die pipe 104 due to the impact of the impact ball 401c when passing through the blanking port 200, and automatic discharging is formed; finally, during the downward movement of the upper die plate 103 and on the basis of the powder raw material in the lower die pipe 104 flying out to the periphery, part of the powder raw material can adhere to the opposite surfaces of the inner ring plate 300 and the outer ring plate 301 under the blocking of the inner ring plate 300 and the outer ring plate 301, so that the subsequent collection difficulty is increased, and therefore, the impact ball 401c intermittently strikes the surface of the annular turntable 102 outside the lower die pipe 104 to form a vibration sense, and the vibration sense can be transmitted to the inner ring plate 300 and the outer ring plate 301 fixedly connected with the annular turntable 102, although the vibration sense is weakened in the process of transmitting the vibration sense from the annular turntable 102 to the inner ring plate 300 and the outer ring plate 301, the slight vibration sense can also ensure that the powder shakes off, and the shakes off powder raw material can not fall on the top end face of the annular turntable 102 due to the fact that the powder splashes again or even leaks into the processing environment due to the strong vibration sense, so that the subsequent collection operation of the powder raw material is convenient.
Referring to fig. 7 and 8, in order to collect the excessive powder raw materials, a spring piece 500 is fixedly connected to one side of the blanking pipe 105 away from the upper die plate 103, the spring piece 500 is integrally located in a space formed by the inner ring plate 300, the outer ring plate 301 and the annular rotary plate 102, the bottom end of the spring piece 500 is attached to the top end surface of the annular rotary plate 102, meanwhile, a rubber sleeve (not numbered in the figure) is further mounted at the bottom end of the spring piece 500, and the rubber sleeve is tightly attached to the top end surface of the annular rotary plate 102, so that the cleaning effect on the top end surface of the annular rotary plate 102 is ensured, two ends of the spring piece 500 are attached to the surfaces of the inner ring plate 300 and the outer ring plate 301 respectively, and one side of the spring piece 500 is protruded towards the blanking pipe 105; that is, after the annular baffle passes through the blanking pipe 105, a small amount of powder raw material is adhered to the top end surface of the annular baffle, meanwhile, the powder raw material falling off from the inner annular plate 300 and the outer annular plate 301 falls on the basis of the top end surface of the annular baffle, in the rotating process of the annular baffle, the powder raw material on the top end surface of the annular baffle is intercepted by the arrangement of the elastic sheet 500 and the rubber sleeve, the powder raw material is temporarily stored at the inner concave surface of the elastic sheet 500, and the powder raw material falls into the lower die pipe 104 by gravity when the lower die pipe 104 reaches the inner concave surface of the elastic sheet 500, so that on one hand, the collection of the powder raw material is realized; on the other hand, the waste of the powder raw material is reduced, and the powder raw material falling into the lower die tube 104 can be filled after passing through the blanking tube 105.
Referring to fig. 7 and 8, further, shaft rods 501 are installed at both ends of the elastic sheet 500, and arc plates 502 are installed on both shaft rods 501 through torsion springs; the two arc plates 502 are oppositely arranged, and the opposite surfaces of the two arc plates 502 are convex surfaces; under the action of the torsion spring, one ends of the two arc plates 502 are respectively abutted against the surfaces of the inner ring plate 300 and the outer ring plate 301, powder raw materials on the top end surface of the annular rotary disc 102 are gathered before being located in the elastic sheet 500, the middle part of the elastic sheet 500 can be gathered after part of the powder raw materials are located in the elastic sheet 500, and the powder raw materials can be scraped into the lower die pipe 104 in the process of moving the lower die pipe 104 to the elastic sheet 500.
Referring to fig. 7, 8, 9 and 10, in order to collect the powder raw material on the top end surface of the annular turntable 102 except the lower die tube 104, a plurality of protruding blocks 503 corresponding to the number of the lower die tube 104 are mounted on each of the inner ring plate 300 and the outer ring plate 301, the protruding blocks 503 are located on the outer side of the lower die tube 104, and the protruding blocks 503 are in extrusion fit with the top of the shaft 501; that is, on the basis of the rotation of the annular turntable 102, the inner ring plate 300 and the outer ring plate 301 fixedly connected with the annular turntable 102 also rotate therewith, and in the process, two corresponding shaft rods 501 are extruded by two protruding blocks 503 outside each lower die pipe 104, so that the two shaft rods 501 move in opposite directions and drive the elastic sheet 500 to deform, so that the powder raw materials in the elastic sheet 500 are further gathered towards the middle, and the powder raw materials are convenient to fall into the blanking pipe 105 for collection.
