[0022] See also Figure 1 As shown, the present invention is a forming device for a pump casing, comprising a stamping die for stamping a circular plate 100 into a pump casing 55, and a loading mechanism for placing the circular plate 100 into the stamping die, and a unloading mechanism for removing the pump casing 55 from the stamping die are provided on one side of the stamping die; simultaneously, when in use, a first conveying line 4 is used to convey the circular plate 100, and a second conveying line 3 is used to convey the pump casing 55.

[0023] In order to facilitate the stamping and forming of the stamping mold, the stamping and forming mold provided by the present invention includes a top plate 14 and a base 1 connected by four pillars 12, a lower template 10 is provided on the upper surface of the base 1, a hydraulic rod 15 is provided through the top of the top plate 14, and the top of the hydraulic rod 15 is connected to the upper template 16; the upper surface of the lower template is recessed downward to form a groove A, and a die is installed inside the groove A, the lower surface of the upper template 16 is recessed upward to form a groove B, and a punch is installed inside the groove B for stamping and forming with the die, and then when in use, the loading mechanism is used to grab the circular plate 100 and place it above the lower template 10, and then the upper template 16 is controlled to move downward, and then the cooperation of the punch and the die is used to realize stamping and forming, and then the circular plate 100 is formed into a pump casing 55.

[0024] Specifically, the feeding mechanism includes a material grabbing and moving mechanism that can move in the horizontal and vertical directions; the material grabbing and moving mechanism includes a horizontally arranged guide rail A2, on which an electric slider A21 is provided, the electric slider A21 is connected to a rotary cylinder 22, the end of the rotary cylinder 22 is connected to a base plate A23, an opening is provided on the base plate A23, a U-shaped frame 25 is provided above the base plate A23 at the opening, a telescopic cylinder A26 is connected to the U-shaped frame A25, the end of the telescopic cylinder A26 is connected to the mounting plate A, and one side of the mounting plate A is provided with a plurality of vacuum suction cups A24 for grabbing the circular plate 100. When in use, the base plate A23 is controlled to be located directly above the first conveyor line 4, and then the telescopic cylinder A is controlled. After 26 is extended, the vacuum suction cup A24 is used to grab the circular plate 100 and then the retraction cylinder A26 is controlled to retract. After controlling the rotary cylinder 22 to rotate 180°, the electric slider A21 is controlled to move along the length direction of the guide rail A2 toward the side close to the stamping die, until the substrate A23 is driven from the gap between the two pillars 12 into between the lower template 10 and the upper template 16. Then the telescopic cylinder A26 is controlled to extend, and the circular plate 100 adsorbed on the vacuum suction cup A24 is released from the vacuum suction cup A24 and placed on the lower template 10. After that, the telescopic cylinder A26 is controlled to retract to the initial state, and then the electric slider A21 is controlled to move along the length direction of the guide rail A2 toward the side away from the stamping die to the initial position.

[0025] In the above, in order to facilitate the control of the circular plate 100 so that it can be accurately placed on the lower template 10 and avoid a large deviation between the center of the circle of the lower template 10 and the center of the circular plate 100 after placement, an induction baffle 40 is provided at the end of the first conveyor line 4, and a detection structure 41 is provided on both sides of the induction baffle 40. The induction baffle 40 is used to calibrate the position of the circular plate 100 conveyed on the first conveyor line 4 in the horizontal first direction, and the detection structure 41 is used to calibrate the position of the circular plate 100 conveyed on the first conveyor line 4 in the horizontal second direction, and the horizontal first direction and the horizontal second direction are perpendicular to each other.

[0026] like Figure 1 As shown, when the conveying direction of the first conveyor line 4 is perpendicular to the length direction of the guide rail A2, the horizontal second direction is the same as the length direction of the guide rail A2, and the horizontal first direction is the same as the conveying direction of the first conveyor line 4.

[0027] Specifically, such as Figure 2, the induction baffle 40 includes a baffle body 401 fixed to the end of the first conveyor line 4 frame. On one side of the baffle body 401, an installation groove A402 is opened along the length direction perpendicular to the first conveyor line 4. On the baffle body 401 on both sides of the installation groove A402, a number of installation grooves B403 are opened; the installation groove B403 and the installation groove A402 cooperate to form a "rich" - shaped structure, and the depth of the installation groove B403 is greater than the depth of the installation groove A402; it also includes a movable baffle 404 in a "rich" - shaped structure. An elastic guiding telescopic rod is connected between one side of the movable baffle 404 and the installation groove B403, and a pressure sensor B is provided on the installation groove A402 or the movable baffle 404. Then, when the circular plate 100 is conveyed to the end of the first conveyor line 4, the outer edge side of the circular plate 100 abuts against the movable baffle 404 at this time. Then, when the pressure sensor B detects a pressure signal, it indicates that the circular plate 100 has moved to the designated position along with the conveyance of the first conveyor line 4. Then, it is convenient to calibrate the position of the circular plate 100 in the horizontal first direction on the first conveyor line 4 at this time.

[0028] Specifically, as Figure 3 , the detection structure 41 includes side plates 410 provided on the frames on both sides of the first conveyor line 4. Electric telescopic rods 411 are provided on the opposite sides of the two side plates 410. The end of the electric telescopic rod 411 is connected to a movable rod 412, and a pressure sensor A413 is provided on the inner wall of the movable rod 412. By setting the detection structure 41, after grasping the circular plate 100 with the vacuum suction cup A24, the telescopic cylinder A26 is controlled to contract until the bottom surface of the circular plate 100 forms a certain height from the conveying surface of the first conveyor line 4. At this time, it is convenient to control the electric telescopic rods 411 on both sides to extend during use. Then, after the electric telescopic rods 411 drive the movable rod 412 to move horizontally, when the two movable rods 412 on both sides respectively abut against the two edge sides of the circular plate 100, by detecting the telescopic lengths of the two electric telescopic rods 411 at this time, the position of the circular plate 100 in the horizontal second direction is calibrated.

[0029] In the above, when the telescopic lengths of the two electric telescopic rods 411 are the same, the circular plate 100 is in the standard position at this time. Then, the electric slider A21 is controlled to move along the length direction of the guide rail A2 until the distance between the electric slider A21 and the right end of the guide rail A2 is L0; when the telescopic length of the left - hand electric telescopic rod 411 is longer than the telescopic length of the right - hand electric telescopic rod 411 by L, then the circular plate 100 is offset to the right at this time. Then, the electric slider A21 is controlled to move along the length direction of the guide rail A2 until the distance between the electric slider A21 and the right end of the guide rail A2 is L1. Then, L1 - L0 = L.

[0030] In order to facilitate detecting the movement of the electric slider A21 to the corresponding position along the length direction of the guide rail A2, a distance sensor for detecting the position of the electric slider A21 on the guide rail A2 is provided at one end of the guide rail A2.

[0031] A fixing seat A13 and a fixing seat B11 for mounting the pillar 12 are respectively provided on opposite sides of the top plate 14 and the base 1 . A plurality of springs 17 and guide rods 18 are connected between the upper template 16 and the top plate 14 .

[0032] Based on the above, in order to facilitate the removal of the stamped pump casing 55 from the stamping die during use, a blanking mechanism is provided on the other side of the stamping die. The blanking mechanism includes a horizontally arranged guide rail B5, on which an electric slider B51 is provided. The electric slider B51 is connected to a telescopic cylinder B52, and the end of the telescopic cylinder B52 is connected to a base plate B53. One side of the base plate B53 is provided with a plurality of vacuum suction cups B54 for grabbing the formed pump casing 55; a vacuum suction cup B54 for conveying the pump casing 55 is provided below the guide rail B5. The second conveyor line 3, when in use, first control the movement of the electric slider B51 to drive the substrate B53 to extend from the gap between the two pillars 12 into the gap between the lower template 10 and the upper template 16, then control the telescopic cylinder B52 to extend and use the vacuum suction cup B54 to grab the pump casing 55, after the pump casing 55 is grabbed, control the telescopic cylinder B52 to retract, then control the movement of the electric slider B51 to control the substrate B53 to move out of the opening between the lower template 10 and the upper template 16, control the telescopic cylinder B52 to extend and control the pump casing 55 to be placed on the second conveyor line 3.
