DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

After the strip airbag 23 expands, it restrains the casting; then the pad 2 is conveyed to the cutting position of the band saw assembly 3 by the conveyor belt 11. As the pad 2 drives the casting to move, the riser of the casting will automatically pass through the band saw of the band saw assembly 3, so that the riser is automatically cut off; then the pad 2 is reset by the conveyor belt 11, and the restraint of the strip airbag 23 on the casting is released at the same time; then the casting is transferred from the pad 2 by the manipulator; then the above process is repeated. Setting a pair of pads 2 and the feeding conveyor 4 can improve the cutting efficiency of the entire casting; and restraining and fixing the casting by the strip airbag 23 can increase the extrusion area of ​​the casting when it is restrained, thereby avoiding local damage to the casting due to excessive pressure.

[0022] The connecting member includes a first hydraulic cylinder 28; the first hydraulic cylinder 28 is installed at the top of the fixed frame 21; the output end of the first hydraulic cylinder 28 is fixedly connected to a linkage frame 281, and the end of the linkage frame 281 away from the first hydraulic cylinder 28 is fixedly connected to a slider 282, and the bottom end of the slider 282 is fixedly connected to the top of the receiving frame 22; the top of the slider 282 is provided with a slide rail 283, and the slide rail 283 is fixedly connected to the surface of the fixed frame 21; the slider 282 is slidably connected to the slide rail 283; after the casting is fixed by the strip airbag 23, the output end of the first hydraulic cylinder 28 drives the linkage frame 281 to move; the end of the linkage frame 281 away from the first hydraulic cylinder 28 drives the slider 282 on the slide The rail 283 slides inside; when the slider 282 moves, it drives the receiving frame 22 at the bottom to move synchronously, so that the receiving frame 22 drives the strip air bag 23 to move, and the strip air bag 23 drives the fixed casting to move synchronously, and the position of the riser on the casting moves synchronously, and the horizontal distance between the riser and the band saw on the band saw assembly 3 is adjusted synchronously; the size and position of the risers of different castings that need to be cut are different; the above process can adjust the cutting position of the casting; and then adjust the cutting position of the riser on the casting, which is convenient for the use of castings of different sizes; it should be pointed out that the casting adjustment distance is set in advance according to the size of the casting and the position of the riser, and the first hydraulic cylinder 28 automatically controls the output when in use.

[0023] A pressure relief valve 27 is fixedly connected to the side of the receiving air box 25; when the strip air bag 23 is inflated, the gas pressure in the strip air bag 23 is the same as the gas pressure inside the receiving air box 25; when the internal pressure of the strip air bag 23 reaches a certain level, that is, the internal pressure when the strip air bag 23 restrains the casting and may cause deformation and damage to the casting, the pressure relief valve 27 connected to the receiving air box 25 will exhaust and release pressure, thereby limiting the internal gas pressure of the strip air bag 23 from continuing to increase, thereby avoiding excessive pressure in the strip air bag 23 causing deformation and damage to the casting due to excessive restraint force.

[0024] The transfer assembly 5 includes a support frame 51; the support frame 51 is installed between the feeding conveyor 4 and the pad 2; the top of the support frame 51 is fixedly connected to a second hydraulic cylinder 52, the output end of the second hydraulic cylinder 52 is fixedly connected to a mounting frame 53, both ends of the mounting frame 53 are fixedly connected to a pair of third hydraulic cylinders 54, the output end of the third hydraulic cylinder 54 is fixedly connected to a connecting rod 55, and the bottom end of the connecting rod 55 is fixedly connected to a clamping plate 56; when the casting on the feeding conveyor 4 is transferred to the top of the pad 2, the mounting frame 53 is driven to move by the second hydraulic cylinder 52, and the mounting frame 53 drives the output end of the third hydraulic cylinder 54 The connecting rod 55 moves synchronously, and when the connecting rod 55 moves, it drives the clamping plate 56 at the bottom to move; when a pair of clamping plates 56 are located on both sides of the casting, they stop, and then the clamping plates 56 at the bottom of the connecting rod 55 are driven by the third hydraulic cylinder 54 to clamp both sides of the casting. It should be pointed out that a cushioning air bag is provided on the side facing the gradual direction of the clamping plate 56 (not shown in the drawings of the specification). When the clamping plate 56 clamps the casting, the cushioning air bag is driven to press onto the surface of the casting, and the pressure area of ​​the casting is increased to prevent the local casting from being damaged by excessive pressure; then the second hydraulic cylinder 52 drives the mounting frame 53 to the pad 2. The top of the pad 2 moves in the same direction as the bottom of the casting on the feeding conveyor 4; when the mounting frame 53 moves, the mounting frame 53 drives the third hydraulic cylinder 54 to move, and the third hydraulic cylinder 54 drives the clamping plate 56 at the bottom of the connecting rod 55 to move synchronously, and the clamping plate 56 drives the clamped casting to move above the pad 2, and stops when the casting reaches the upper position of the pad 2; the casting stops when it is transferred to the top of the pad 2, at this time the connecting rod 55 is not blocked by the fixing frame 21, and then the casting is restrained and fixed by the strip airbag 23; the specific process of the strip airbag 23 expanding and restraining the casting is as described above As shown; then the second hydraulic cylinder 52 drives the mounting frame 53 to move away from the pad 2, the mounting frame 53 drives the third hydraulic cylinder 54 to move, and the third hydraulic cylinder 54 drives the clamping plate 56 at the bottom end of the connecting rod 55 to move. At this time, the clamping plate 56 is squeezed and restrained by the strip airbag 23 and the casting; after the clamping plate 56 is pulled out from between the strip airbag 23 and the casting, the casting is completely restrained by the strip airbag 23; and in the process of the casting being restrained by the strip airbag 23; the casting is continuously clamped and fixed by the clamping plate 56; the movement of the casting position is avoided in the process of the strip airbag 23 squeezing and restraining the casting.

[0025] A pair of receiving rollers 58 are rotatably connected at both ends of the clamping plate 56, and a rotating belt 57 is sleeved on the outer side of the clamping plate 56; the pair of receiving rollers 58 are located inside the rotating belt 57; when the clamping plate 56 is pulled out, the rotating belt 57 rotates on the side of the clamping plate 56, thereby avoiding friction between the clamping plate 56 and the casting surface during the pulling process, thereby protecting the casting; A pair of fourth hydraulic cylinders 59 are fixedly connected to the top of the clamping plate 56, and a brake block 591 is fixedly connected to the output end of the fourth hydraulic cylinder 59; the position of the brake block 591 can be controlled by the fourth hydraulic cylinder 59. Specifically, when the clamping plate 56 transfers the casting, the fourth hydraulic cylinder 59 drives the brake block 591 to move to the top of the receiving roller 58. There is friction between the brake block 591 and the top of the receiving roller 58, so that the receiving roller 58 is restricted from rotating. Then, when the clamping plate 56 clamps the casting, the brake block 591 is controlled to brake the top of the receiving roller 58. The friction between the receiving roller 58 and the rotating belt 57 limits the rotation of the rotating belt 57 on the side of the clamping plate 56, thereby ensuring that the clamping plate 56 clamps the casting. and when the clamping plate 56 is pulled out from between the casting and the strip airbag 23, the fourth hydraulic cylinder 59 drives the brake block 591 to separate from the top of the receiving roller 58, thereby releasing the restriction on the friction force of the brake block 591 on the top of the receiving roller 58, and then the rotating belt 57 can smoothly rotate on the side of the clamping plate 56, thereby ensuring the stability of the casting transfer while protecting the casting; it should be pointed out that the buffer airbag on the side of the clamping plate 56 facing the casting is located inside the rotating belt 57, and the rotating belt 57 is supported by the buffer airbag, and the rotating belt 57 can be deformed synchronously when clamping the casting; therefore, it will not affect the protection process of the casting by the buffer airbag during the clamping process of the clamping plate 56.

[0026] The clamping plate 56 includes a first set of plates 561 and a second set of plates 562; the top end of the first set of plates 561 is fixedly connected to the bottom end of the connecting rod 55; a pair of plug-in slots are formed at one end of the second set of plates 562 facing the first set of plates 561; A pair of plug-in rods 563 are provided at one end of the first set of plates 561 facing the second set of plates 562, and the plug-in rods 563 are inserted into the plug-in slots; a connecting spring is fixedly connected between the first set of plates 561 and the second set of plates 562; the connecting spring is continuously in a compressed state; By fixing a connecting spring between the first set of plates 561 and the second set of plates 562, the first set of plates 561 and the second set of plates 562 are kept in a state of mutual repulsion, the rotating belt 57 is kept in a taut state, and the service life is improved; and the plug-in rod 563 is inserted into the plug-in slot, so that the first set of plates 561 and the second set of plates 562 maintain linear movement, ensuring the normal use of the splint 56.

[0028] The end of the detection head 63 away from the sixth hydraulic cylinder 62 is set as a pointed end; it is convenient for the detection head 63 to be inserted into the riser, and the detection head 63 is made of rubber; it is prevented that the detection head 63 is stuck in the riser when moving, and the riser is damaged by excessive squeezing, which further causes deformation and damage to the part of the casting that contacts the riser.
