The second sawing part includes a second mounting block, a second Y-axis sliding table, an X-axis fixing plate and two second sawing structures. The second sawing structure includes an X-axis mounting plate, a second X-axis sliding table, a second X-axis Two motors and a second saw blade. The clamping part is composed of two clamping structures, and the clamping structure includes a third mounting block, a third X-axis slide table, a lower positioning block, a supporting block, a top block, a hydraulic cylinder and an upper pressing block. This application can saw four sprue risers at the same time, thereby improving sawing efficiency.

However, the applicant found in actual use that since the lower positioning block and the upper pressing block are only clamped on the head ring portion of the piston blank, the tail of the piston blank is not supported and clamped. If the staff just lets go after the piston blank is placed on the lower positioning block, under the effect of the self gravity of the afterbody of the piston blank, the piston blank can topple over and fall. Therefore, after the piston blank is placed on the lower positioning block, the staff needs to hold the piston blank by hand to keep the piston blank stable until the upper pressing block descends and presses the piston blank on the lower positioning block to let go. The process of placing the piston blank is time-consuming and labor-intensive, and poses a safety hazard.

Therefore, the present invention proposes a technical solution to solve the above-mentioned problem that the staff have to wait for the upper pressing block to press the piston blank before letting go when placing the piston blank.

The top end of the first threaded rod 9 is fixed with a first rotating block 10 . The bottom end of the first threaded rod 9 is fixed with an anti-sway plate 11 .

A lower extension plate 12 corresponding to the upper extension plate 8 is fixed on the rear side of the lower positioning block 3 . A top end of the lower extension plate 12 defines a second sliding slot 13 extending forward and backward. A screw mandrel 14 is rotatably connected in the second chute 13 . The front end of the screw rod 14 passes through the lower extension plate 12 and is fixed with a second rotating block 15 . A nut seat 16 that moves along the second sliding groove 13 is sleeved on the outside of the screw rod 14 in a threaded manner. The outer wall of the nut seat 16 is attached to the groove wall of the second sliding groove 13 . The top end of the nut seat 16 passes through the second sliding slot 13 and is fixed with a telescopic rod 17 . The telescoping rod 17 includes an outer tube 18 and an inner rod 19 . The bottom end of the outer tube 18 is fixedly connected with the top end of the nut seat 16 . A top end of the outer tube 18 defines a first sliding slot 20 extending longitudinally. The bottom end of the inner rod 19 is inserted into the first sliding slot 20 and moves along the first sliding slot 20 . The outer wall of the outer tube 18 is screwed with a tightening bolt 21 inserted into the first chute 20 for tightening the inner rod 19 . The top end of the inner rod 19 is located outside the first chute 20 and is fixed with a supporting plate 22 . A positioning plate 23 is fixed on the top rear side of the supporting plate 22 .

Working principle: the first threaded rod 9 is rotated by the first rotating block 10, and the first threaded rod 9 can move up and down, thereby driving the anti-sway plate 11 to move up and down. Adjust the height of the anti-warping plate 11 according to the size specification of the piston blank.

Loosen the jacking bolt 21, the inner rod 19 can move up and down in the first chute 20, thereby adjusting the length of the telescopic rod 17, and then tighten the jacking bolt 21 after adjustment, the telescopic rod 17 can be fixed at the current length . Changing the length of the telescopic rod 17 can drive the supporting plate 22 to move up and down, thereby adjusting the height of the supporting plate 22 according to the size specification of the piston blank.

After adjusting the height of the supporting plate 22, the second rotating block 15 is rotated. The second rotating block 15 drives the screw mandrel 14 to rotate. The threaded mandrel 14 drives the nut seat 16 to move back and forth along the second chute 13 . The nut seat 16 can drive the telescopic rod 17 to move back and forth.

Then the head of the piston blank is placed on the lower positioning block 3, and the afterbody of the piston blank can be supported by the supporting plate 22, so that the piston blank remains stable. And the rear side of the piston blank is attached to the positioning plate 23 . In this way, the piston blank can be quickly positioned, and the piston blank is prevented from shifting back and forth when the piston blank is placed, which will cause errors when cutting the riser on the piston blank. The process of placing the piston blank is less time-consuming and labor-intensive, and the safety is higher by eliminating the need for a worker to hold the piston blank until it is clamped. And when the upper pressing block 7 is pressing the piston blank, the anti-sway plate 11 is pressing the top end of the tail of the piston blank. When preventing the upper pressing block 7 from pressing the piston blank, the tail of the piston blank is upturned.

Embodiment two:

The difference from the first embodiment is that the top end of the lower extension plate 12 is no longer provided with the second sliding groove 13, and the corresponding screw rod 14 and nut seat 16 are no longer provided. Instead, as shown in FIGS. 4 and 5 , a slide plate 24 is fixed on the bottom front side of the outer tube 18 . The bottom end of the sliding plate 24 is attached to the top end of the lower extension plate 12 . A top end of the lower extension plate 12 defines a T-shaped sliding slot 25 . A T-shaped slide block 26 is slidably connected in the T-shaped chute 25 . The top end of the T-shaped slide block 26 is flush with the top end of the lower extension plate 12 and is fixed with a second threaded rod 27 . The top end of the second threaded rod 27 passes through the sliding plate 24 and is fitted with a fastening nut 28 .

When the telescopic rod 17 needs to be moved back and forth, the fastening nut 28 is unscrewed, and the T-shaped slide block 26 can slide back and forth in the T-shaped chute 25 . The T-shaped slider 26 drives the second threaded rod 27 to move back and forth. The second screw drives the sliding plate 24 to move back and forth. The slide plate can drive the telescopic rod 17 to move back and forth.
