DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention belong to the protection scope of the present invention.

[0020] like Figures 1 to 8As shown, the present invention includes a working platform 1 and a punching die 2 installed on the working platform 1, a punching machine 3 is installed on the working platform 1 above the punching die 2, the punching die 2 is used to place a fixed MIM product 11 to be punched, the punching machine 3 is used to punch the runner of the MIM product 11, and a buffer fixture 4, a positioning fixture 5, a gate repair machine 6 and a belt conveyor 7 are sequentially arranged on the discharge side of the punching die 2, the buffer fixture 4 is fixedly installed on the working platform 1 through a base, the buffer fixture 4 is used to temporarily store the MIM product 11 after punching, and a first transplanting manipulator 8 is installed on the working platform 1 above the buffer fixture 4 and the punching die 2. The transfer robot 8 is used to shift the punched MIM product 11 from the punching die 2 to the cache jig 5. The positioning jig 5 is installed on the working platform 1 through the feeding mechanism 9. The feeding mechanism 9 can drive the positioning jig 5 to move to the gate repair machine 6. The gate repair machine 6 and the belt conveyor 7 are installed on the working platform 1. A second transfer robot 10 is installed on the working platform 1 above the cache jig 4, the positioning jig 5, the gate repair machine 6 and the belt conveyor 7. The second transfer robot 10 shifts the MIM product 11 on the cache jig to the positioning jig 5. After the gate surface of the MIM product is trimmed, the MIM product is shifted to the belt conveyor.

[0021] In the present device, the first transfer robot 8 is set up to shift the MIM product 11 punched on the punching die 2 to the buffer fixture 4. Since a small gap needs to be ensured between the gate surface of the MIM product 11 and the gate trimming machine 6, it is not conducive to directly placing the MIM product 11 into the positioning fixture 5. Therefore, the buffer fixture 4 is set up to facilitate the transfer of the MIM product 11, so that the feeding mechanism 9 can accurately feed the positioning fixture 5. The feeding mechanism 9 can accurately shift the positioning fixture 5 to the gate trimming machine 6 to realize the trimming action of the gate trimming machine 6 on the gate surface of the MIM product 11. The gate trimming machine 6 is a structure specially designed for trimming the gate surface of the MIM product 11, which can effectively ensure the trimming accuracy of the gate surface of the MIM product 11. The second transfer robot 10 is used for equidistant displacement of the MIM product 11 between the three positions of the cache fixture 4, the positioning fixture 5 and the belt conveyor 7, which can effectively improve the trimming efficiency. Compared with the traditional manual gate trimming, the advantages of the device are: the device is designed with a gate trimming machine 6 according to the structure of the gate surface of the MIM product 11. The gate trimming machine 6 can automatically trim the gate surface of the MIM product 11 after punching and cutting under the cooperation of the first transplanting robot 8 and the second transplanting robot 10. The structure of the device is novel and the degree of automation is high. The MIM product 11 does not require manual participation in the punching and cutting, gate surface trimming and material feeding stations, and can be completed automatically. This not only reduces the labor level and solves the problem of worker proficiency requirements, but also greatly improves the efficiency of trimming and effectively guarantees the trimming accuracy of the gate surface of the MIM product 11.

[0022] In order to further improve the production efficiency and increase the number of MIM products 11 trimmed each time, the number of the cache jigs 4 is two groups, and the number of the cache jigs 4 in each group is two. The number of the positioning jigs 5 is two groups, and the number of the positioning jigs 5 in each group is two. The position of the positioning jig 5 corresponds to the cache jig 4. The number of the gate trimming machines 6 is two groups, and the position of the gate trimming machines 6 corresponds to the position of the positioning jig 5. Such an arrangement structure is that a group of gate trimming machines 6, a group of positioning jigs 5 and a group of cache jigs 4 cooperate with each other, so that a group of gate trimming machines 6 can trim two MIM products 11. In this way, two groups of gate trimming machines 6 and two groups of gate trimming machines 6 can trim four MIM products 11 at the same time.

[0023] Furthermore, the gate repair machine 6 includes a base 61, a limit plate 62, a slide plate 63, a drive cylinder 64 and a gate repair assembly. The drive cylinder 64 is a prior art and is directly purchased as a finished product according to the pressure, stroke, etc. used. The base 61 is fixedly installed on the working platform 1, and vertical plates are vertically installed at both ends of the base 61. The limit plate 62 is fixedly installed at the lower part between the two vertical plates. The tops of the two vertical plates are symmetrically processed with guide grooves. The slide plate 63 is slidably installed in the groove between the two vertical plates, and a push rod is vertically installed at one end of the slide plate 63. 65, a flat plate is installed at the lower end of the push rod 65, the cylinder seat of the driving cylinder 64 is installed on the base 61, the piston rod of the driving cylinder 64 is fixedly connected to the flat plate, two movable plates 66 are arranged in parallel on both sides of the slide plate 63, and the movable plates 66 are slidably installed on the base 61. The number and position of the gate repair components correspond to each group of positioning fixtures 5. The number of gate repair components on a group of gate repair 6 is two, corresponding to the number and position of each group of two positioning fixtures 5. The gate repair components include two first handles 67 and second handles arranged opposite to each other. 68, a first blade 69 is installed at the end of the first handle 67 close to the positioning fixture 5, and a second blade 610 is installed at the end of the second handle 68. The first handle 67 is vertically installed on the bottom surface of the slide plate 63, and the second handle 68 is vertically installed on the bottom surface of the movable plate 66. Two first inclined grooves 611 are processed on the limiting plate 62 below the first handle 67, and two first sliding rods 612 are installed at intervals on the bottom surface of the first handle 67. The first sliding rod 612 is slidably installed in the first inclined groove 611. Two second inclined grooves 613 are processed on the limiting plate 62, two second slide bars 614 are installed at intervals on the bottom surface of the second tool handle 68, the second slide bars 614 are slidably installed in the second inclined grooves 613, and rolling bearings 615 are rotatably installed on both sides of the slide plate 63 between the first tool handle 67 and the second tool handle 68, the rolling bearings 615 are in sliding contact with the movable plate 66, a protective cover is detachably installed on the top surface of the base 61, and a clamping mechanism matching the positioning fixture 5 is provided on the protective cover close to the side of the positioning fixture 5, such as Figures 7-8As shown, the gate surface of the MIM product 11 is two symmetrical inclined surfaces. When the gate surface of the MIM product 11 is trimmed, the working principle of the gate trimming machine 6 is: when the feeding mechanism 9 sends the MIM product 11 on the positioning fixture 5 to the position of the gate trimming assembly, the clamping mechanism fixes the MIM product 11. At this time, the piston rod of the driving cylinder 64 is extended, and the slide plate 63 is pushed to move forward through the push rod 65. During the process of the forward movement of the slide plate 63, the first tool handle 67 and the first slide bar 612 connected thereto are driven to slide along the first inclined groove 611. At the same time, during the process of the forward movement of the slide plate 63, the direction of rotation of the rolling bearing 615 is the same as that of the first inclined groove 611. The sliding plate 63 moves in the opposite direction to the forward direction, so that the rolling bearing 615 can drive the movable plate 66 to move in the reverse direction through friction rotation with the movable plate 66 during the rotation process, thereby driving the second tool handle 68 and the second slide bar 614 connected thereto to move along the second inclined groove 613. Due to the friction transmission mode of the rolling bearing 615, the first tool handle 67 and the second tool handle 68 can move toward each other in the corresponding first inclined groove 611 and the second inclined groove 613, thereby driving the first blade 69 and the second blade 610 to move toward each other along the inclined surface of the MIM product 11, so that the first blade 69 and the second blade 610 are close to each other, so as to achieve the following. Figure 7 The first blade 69 and the second blade 610 are controlled to be closed. When the first blade 69 and the second blade 610 move toward each other, the gate surface of the MIM product 11 can be trimmed. When the gate surface of the MIM product 11 is trimmed, the piston rod of the driving cylinder 64 is shortened, and the slide plate 63 is pushed to move in the opposite direction through the push rod 65. When the slide plate 63 moves in the opposite direction, the first tool handle 67 and the first slide bar 612 connected thereto are driven to slide along the first inclined groove 611. At the same time, when the slide plate 63 moves in the opposite direction, the direction of rotation of the rolling bearing 615 is opposite to the direction of the reverse movement of the slide plate 63. On the contrary, during the rotation process, the rolling bearing 615 can drive the movable plate 66 to move forward through the friction rotation with the movable plate 66, thereby driving the second tool handle 68 and the second slide bar 614 connected thereto to move along the second inclined groove 613. Due to the friction transmission mode of the rolling bearing 615, the first tool handle 69 and the second tool handle 610 can move in the corresponding first inclined groove 611 and the second inclined groove 613 in the opposite direction, thereby driving the first blade 69 and the second blade 610 to move in the opposite direction along the inclined surface of the MIM product 11, so that the first blade 69 and the second blade 610 are gradually separated, so as to achieve the following. Figure 8 The control of opening the first blade 69 and the second blade 610 shown in the figure completes the trimming of the casting surface of the MIM product 11, making it easier for the second transplanting robot 10 to shift the MIM product 11.

[0024] Preferably, in order to ensure the synchronization of the mutual movement of the slide plate 63 and the movable plate 66, and to ensure the synchronization and stability of the opening and closing of the first blade 69 and the second blade 610, auxiliary bearings 616 are rotatably installed on both sides of the slide plate 63 between two adjacent groups of gate repair components, and the auxiliary bearings 616 and the rolling bearings 615 have the same rotation direction; in order to increase the service life of the first blade 69 and the second blade 610, the first blade 69 and the second blade 610 are ceramic blades, and the cross-sectional shape of the first blade 69 and the second blade 610 is a triangle. In actual use, the shape of the first blade and the second blade It can be designed according to the shape of the gate surface of the MIM product, and the inclined surfaces of the first blade 69 and the second blade 610 correspond to the gate surface of the MIM product 11; in order to ensure that the movement stroke of the slide plate 63 can be limited during the forward movement, a limiting rod 617 is vertically installed on the base 61 away from the end of the driving cylinder 64, and the end of the slide plate 63 is processed with a semicircular groove corresponding to the limiting rod 617. During the forward movement of the slide plate 63, the limiting rod 617 can limit the stroke of the slide plate 63 to prevent the first blade 69 and the second blade 610 from colliding when closing.

[0025] Furthermore, the feeding mechanism 9 includes a feeding cylinder 91, a support frame 92 and a feeding plate 93. The feeding cylinder 91 is a prior art, and the finished product is directly purchased according to the pressure, stroke and other parameters used. The support frame 92 is fixedly installed on the working platform 1, and the feeding plate 93 is slidably installed on the support frame 92. The positioning fixture 5 is fixedly installed on the feeding plate 93 near the side of the gate repairing machine 6, and the positioning fixture 5 is installed on the edge of the feeding plate 93. This is convenient for the MIM product 11 to be placed on the positioning fixture 5, and the gate surface of the MIM product 11 does not interfere with the edge of the feeding plate 93, which is convenient for the gate surface of the MIM product 11 to be repaired. A support plate 94 is vertically installed on the part, and the cylinder seat of the feeding cylinder 91 is installed on the supporting frame 92. The piston rod of the feeding cylinder 91 is fixedly connected to the support plate 94. When the second transplanting robot 10 shifts the MIM product 11 on the buffer fixture 4 to the positioning fixture 5, the piston rod of the feeding cylinder 91 extends, and drives the feeding plate 93 to move toward the gate repairing machine 6 through the support plate 94. When the MIM product 11 on the positioning fixture 5 contacts the gate repairing machine 6, the feeding cylinder 91 stops moving. At this time, the gate repairing machine 6 trims the gate surface of the MIM product 11. After the gate surface is trimmed, the piston rod of the feeding cylinder 91 retracts, driving the feeding plate 93 to return to its original position. Preferably, in order to ensure that the feed plate 93 is stable during movement, a guide plate 95 is installed at the bottom of the positioning jig 5, and a plurality of guide rods 96 are fixedly installed between the guide plate 95 and the support plate 94, so as to improve the stability of the feed plate 93 and the positioning jig 5 during movement and ensure the precise feeding of the positioning jig 5.

[0026] Further, the second transplanting manipulator 10 includes a bracket 101, a horizontal module 102, a lifting module I 103, and a lifting module II 104. The horizontal module 102 adopts a gear rack structure or a cylinder-driven moving structure in the prior art. The bracket 101 is fixedly installed on the working platform 1, and the horizontal module 102 is installed above the bracket 101. A translation template 105 is installed on the horizontal module 102. The horizontal module 102 can drive the translation template 105 to move back and forth left and right. The lifting module I 103 and the lifting module II 104 are symmetrically installed at both ends of the translation template 105, and the lifting module I 103 and the lifting module II 104 adopt the cylinder structure in the prior art. The lower end of the lifting module I 103 is installed with a vacuum suction cup I 106, and the lower end of the lifting module II 104 is installed with a vacuum suction cup II 107. The vacuum suction cup I 106 and the vacuum suction cup II 107 are rectangular structures. The bottoms of the vacuum suction cups I 106 and the vacuum suction cups II 107 are both installed with a plurality of suction nozzles corresponding to the cache fixture 4. The vacuum suction cups I 106 and the vacuum suction cups II 107 are provided with a vacuum pump to connect to the vacuum pump. The structure can realize the work of picking up and placing parts by the suction nozzle by using the principle of suction and exhaust, and the distance between the vacuum suction cup I 106 and the vacuum suction cup II 107 is the same as the distance between the buffer fixture 4 and the gate repair machine 6, so that the second transplanting robot 10 can realize the equal distance displacement of the MIM product between the three positions of the buffer fixture 4, the positioning fixture 5 and the belt conveyor 7, that is, when the suction nozzle on the vacuum suction cup I 106 sucks the MIM product 11 on the buffer fixture 4, the suction nozzle on the vacuum suction cup II 107 can also synchronously suck the gate repair surface on the positioning fixture 5 When the suction nozzle on the vacuum suction cup Ⅰ106 shifts the MIM product 11 to the positioning fixture 5, the suction nozzle on the vacuum suction cup Ⅱ107 can also synchronously shift the MIM product 11 after the gate surface is trimmed to the belt conveyor 7, so that the continuous shift of the MIM product 11 between the cache fixture 4, the positioning fixture 5 and the belt conveyor 7 can be achieved. The structure of the first transplanting robot 8 is similar to that of the second transplanting robot 10. The difference is that the first transplanting robot 8 only needs to be provided with a lifting module and a vacuum suction cup.
