Description

Technical Field

[0001] This utility model relates to the field of impeller and stator manufacturing technology, specifically to an oven for shaping polyurethane impellers and stators. Background Technology

[0002] An impeller is a disk equipped with moving blades. It refers both to the core component of an impulse turbine rotor and, more broadly, to the disk and rotating blades. Its structure consists of a rim (where the moving blades are mounted), a surface (connecting parts), and a hub (a thickened stress-reducing zone). Balance holes are provided on the impeller to balance axial thrust and guide leaking steam. Based on their form, they are classified as closed, semi-open, and open, suitable for transporting clean liquids, liquids containing suspended solids, and high-viscosity fluids, respectively.

[0003] In the existing technology, polyurethane impeller stators need to be baked in an oven during production and shaping. High temperature is used to accelerate the shaping of polyurethane impeller stators. However, it is troublesome to remove them after baking. The high temperature may burn the operators, which is not conducive to the safety of the overall production work. Therefore, it needs to be improved. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an oven for shaping polyurethane impeller stators during production, which solves the technical problems in the prior art where it is troublesome to remove the parts after baking and the high temperature may burn the operators.

[0005] According to one aspect, at least one embodiment of the present invention provides an oven for shaping polyurethane impeller stators during production, comprising: an oven body, a door at the front end of the oven body, a heating element and an automatic removal mechanism inside the oven body; the automatic removal mechanism includes a slide rod, a fixing block and a spring telescopic rod, the slide rod being fixedly connected to the inner side wall of the oven body, a placement rack slidably connected to the surface of the slide rod, a placement column fixedly connected to the top of the placement rack, a polyurethane impeller stator body being disposed on the surface of the placement column, and two sets of moving blocks fixedly connected to the rear end of the placement rack. Both sets of movable blocks have slots on their adjacent sides. The fixed block is fixedly connected to the rear end of the oven body. Both sides of the fixed block have grooves. Both sets of grooves have telescopic springs inside. Both sets of grooves have arc-shaped blocks slidably connected to them through the telescopic springs. The fixed block has a hydraulic chamber fixedly connected inside. One end of the hydraulic chamber has a piston slidably connected to a piston rod A. The other two ends of the hydraulic chamber have pistons slidably connected to piston rods B. The spring telescopic rod is fixedly connected to the rear end of the oven body. The top of the placement rack has a speed control mechanism.

[0006] For example, in at least one embodiment of the present invention, an oven for shaping polyurethane impeller stators is provided, which further includes: a handle is provided at the front end of the oven door, and the placement rack is hollowed out as a whole. The oven door can be opened by the handle, and the hollowed-out placement rack allows hot air to flow.

[0007] The opening size of the slot is equal to the opening size of the groove, and one-third of the arc-shaped block is initially located in the slot. The arc-shaped block is stuck in the slot, preventing the placement rack from moving to the front end.

[0008] The arc surface of the arc block faces the front end of the fixed block, the depth of the groove is greater than the length of the arc block, and the arc surface of the arc block can be completely retracted into the groove when it is squeezed.

[0009] The telescopic end of the spring telescopic rod initially abuts against the rear end of the placement frame, and the spring inside the spring telescopic rod is initially compressed. When the spring inside the spring telescopic rod rebounds, it will drive the placement frame to move towards the front end.

[0010] The end of piston rod A away from the hydraulic chamber is connected to the rear end of the oven body and is slidably connected. The ends of the two sets of piston rods B away from the hydraulic chamber are respectively fixedly connected to two sets of arc blocks. When piston rod A moves to the rear end, it will drive the two sets of piston rods B to move into the hydraulic chamber through the hydraulic pressure in the hydraulic chamber.

[0011] According to another aspect, at least one embodiment of the present invention also provides a speed control mechanism including a connecting frame, one end of which is fixedly connected to the top of the placement frame, and the other end of which is rotatably connected to a roller. The surface of the roller is provided with an opening groove, and an elastic spring is provided inside the opening groove. A resistance block is elastically connected inside the opening groove through the elastic spring.

[0012] For example, in at least one embodiment of the present invention, an oven for shaping polyurethane impeller stators is provided, which further includes: the roller is generally circular, and the side of the roller abuts against the inner wall of the oven body, and the roller rotates when it moves and rubs against the inner wall of the oven body.

[0013] The resistance block is initially completely inside the opening slot, and the elastic force of the spring is greater than the frictional force between the resistance block and the opening slot.

[0014] The resistance block is generally square, and the end of the resistance block away from the elastic spring is uneven. When the uneven end of the rubber resistance block comes into contact with the inner wall of the oven body, it will generate greater resistance.

[0015] The beneficial effects of the embodiments of this utility model are as follows: This invention incorporates an automatic removal mechanism, which, when the polyurethane impeller stator body is placed on the placement column and the placement rack is pushed into the oven body for baking and shaping, uses components such as arc-shaped blocks and slots to fix the position of the placement rack. When baking is complete and it is necessary to remove the rack, the piston rod A is pulled to the rear end, at which point the placement rack automatically pops out of the oven body, facilitating the subsequent removal of the polyurethane impeller stator body.

[0016] This invention incorporates a speed control mechanism, which, through components such as rollers, springs, and resistance blocks, controls the speed at which the rack automatically pops out of the oven body. This prevents the rack from popping out too quickly and hitting others, or causing the polyurethane impeller stator to fall off, thus effectively improving overall safety.

[0025] like Figures 1-7 The illustration shows an oven for shaping polyurethane impeller stators in one embodiment of the present invention, comprising: an oven body 1, a door 2 at the front end of the oven body 1, a heating tube 5 and an automatic removal mechanism 6 inside the oven body 1; the automatic removal mechanism 6 includes a slide rod 61, a fixing block 67 and a spring telescopic rod 614, the slide rod 61 being fixedly connected to the inner wall of the oven body 1, a placement rack 62 being slidably connected to the surface of the slide rod 61, a placement column 63 being fixedly connected to the top of the placement rack 62, a polyurethane impeller stator body 64 being disposed on the surface of the placement column 63, and two sets of moving blocks 65 being fixedly connected to the rear end of the placement rack 62. 5. Each side of the oven body 1 has a slot 66. The fixing block 67 is fixedly connected to the rear end of the oven body 1. The fixing block 67 has a groove 68 on both sides. Each groove 68 has a telescopic spring 69 inside. Each groove 68 has an arc-shaped block 610 slidably connected to it through the telescopic spring 69. The fixing block 67 has a hydraulic chamber 611 fixedly connected inside. One end of the hydraulic chamber 611 has a piston rod A612 slidably connected to it. The other two ends of the hydraulic chamber 611 have piston rods B613 slidably connected to it. The spring telescopic rod 614 is fixedly connected to the rear end of the oven body 1. The top of the rack 62 has a speed control mechanism 7.

[0026] In some examples, the front end of the door 2 is provided with a handle 3, and the shelf 62 is hollowed out. The door 2 can be opened by the handle 3, and the hollowed-out shelf 62 allows hot air to flow.

[0027] The opening size of the slot 66 is equal to the opening size of the groove 68, and one-third of the arc-shaped block 610 is initially located in the slot 66. The arc-shaped block 610 is stuck in the slot 66, preventing the placement rack 62 from moving to the front end.

[0028] The arc surface of the arc block 610 faces the front end of the fixed block 67, the depth of the groove 68 is greater than the length of the arc block 610, and the arc surface of the arc block 610 can be completely retracted into the groove 68 when it is squeezed.

[0029] In the initial state, the telescopic end of the spring telescopic rod 614 is in contact with the rear end of the placement frame 62, and the spring inside the spring telescopic rod 614 is initially compressed. When the spring inside the spring telescopic rod 614 rebounds, it will drive the placement frame 62 to move towards the front end.

[0030] The end of piston rod A612 away from hydraulic chamber 611 is connected to the rear end of oven body 1 and is slidably connected. The ends of two sets of piston rods B613 away from hydraulic chamber 611 are respectively fixedly connected to two sets of arc blocks 610. When piston rod A612 moves to the rear end, it will drive the two sets of piston rods B613 to move into hydraulic chamber 611 through hydraulic pressure in hydraulic chamber 611.

[0031] For example, such as Figures 1-7 As shown, the polyurethane impeller stator body 64 is fitted onto the placement column 63, and the placement rack 62 is pushed into the oven body 1. The telescopic end of the spring telescopic rod 614 is compressed, and the movement of the placement rack 62 to the rear end will drive the moving block 65 to move to the rear end. Initially, the rear end of the moving block 65 will press against the arc surface of the arc block 610, causing the arc block 610 to completely retract into the groove 68, and the telescopic spring 69 will be compressed. When the slot 66 moves and coincides with the groove 68, the telescopic spring 69 rebounds and drives the arc block 610 to be inserted into the slot 66. At this time, the position of the placement rack 62 is... The oven is fixed in place, and the oven door 2 is closed for baking and shaping. When baking is finished, the oven door 2 is opened, and the piston rod A612 is pulled to the rear. The piston rod A612 moves to the rear and drives the piston rod B613 to move into the hydraulic chamber 611 through the hydraulic pressure. At this time, the piston rod B613 will drive the arc block 610 to leave the slot 66. Then, the spring in the spring telescopic rod 614 rebounds and drives the placement rack 62 to move to the front and remove it from the oven body 1. This allows the polyurethane impeller stator body 64 to cool down, making it easier to remove later and making the overall use more convenient.

[0032] like Figures 1-7 As shown, the speed control mechanism 7 in another embodiment of the present invention includes a connecting frame 71. One end of the connecting frame 71 is fixedly connected to the top of the placement frame 62, and the other end of the connecting frame 71 is rotatably connected to a roller 72. The surface of the roller 72 is provided with an opening groove 73, and an elastic spring 74 is provided inside the opening groove 73. A resistance block 75 is elastically connected inside the opening groove 73 through the elastic spring 74.

[0033] In some examples, the roller 72 is circular in shape, and the side of the roller 72 abuts against the inner wall of the oven body 1. The roller 72 rotates when it moves and rubs against the inner wall of the oven body 1.

[0034] In the initial state, the resistance block 75 is completely inside the opening slot 73, and the elastic force of the spring 74 is greater than the frictional force between the resistance block 75 and the opening slot 73.

[0035] The resistance block 75 is square in shape, and the end of the resistance block 75 away from the elastic spring 74 is uneven. When the uneven end of the rubber resistance block 75 comes into contact with the inner wall of the oven body 1, it will generate greater resistance.

[0036] For example, such as Figures 1-7 As shown, during the process of the spring rebounding inside the spring telescopic rod 614, which drives the placement rack 62 to move forward and out of the oven body 1, the roller 72 will rotate when it moves and rubs against the inner wall of the oven body 1. At this time, the centrifugal force generated by the rapid rotation of the roller 72 will throw the resistance block 75 out of the opening slot 73. When the uneven end of the rubber resistance block 75 contacts the inner wall of the oven body 1, it will generate greater resistance, thereby slowing down the speed at which the placement rack 62 moves out, preventing the placement rack 62 from popping out of the oven body 1 too fast and hitting others, or causing the polyurethane impeller stator body 64 to fall off, effectively improving the overall safety.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
