DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0027] Example:

[0028] like Figure 1 As shown, a double slider supporting edge cutting die is used to remove burrs from die castings. Generally, die castings will have local burrs and slag bags after molding. The double slider 20 supports the edge cutting die to cut the burrs of the die castings.

[0029] The double-slider support edge cutting die includes: a lower pressing plate 1 and an upper pressing plate 2, the upper pressing plate 2 is fixedly connected to an upper punching plate 3, and the upper punching plate 3 is fixedly connected to a plurality of first cutter heads 4 for cutting burrs of die castings. The first cutter heads 4 include two types of cutting the outside of the die castings and cutting the inside of the die castings. The first cutter heads 4 are all profiling cutter heads, and the profiling structure drives the cutter heads to cut off the burrs and slag bags of the die castings. The first cutter heads 4 are detachably connected to the upper punching plate 3.

[0030] A first buffer component is provided between the upper punching plate 3 and the upper pressing plate 2 , and a supporting component is provided on the lower surface of the upper punching plate 3 extending from the buffer component.

[0031] like Figure 1 , Figure 3As shown, the first buffer assembly includes: a displacement plate 10 and a plurality of first guide pillars 9 arranged between the upper pressure plate 2 and the upper punching plate 3, and a plurality of first compression springs 11 sleeved on the first guide pillars 9 are arranged between the displacement plate 10 and the upper pressure plate 2. The first guide pillars 9 guide the displacement plate 10, and the first compression springs 11 drive the displacement plate 10 to fit with the upper punching plate 3.

[0032] like Figures 1 to 5 As shown, the support assembly includes: a plurality of displacement columns 12 fixedly connected to the displacement plate 10, the displacement columns 12 pass through the upper stamping plate 3 and are fixedly connected to a positioning block 13 that cooperates with the die casting, the positioning block 13 is provided with a buffer groove, and a buffer block 14 is matched in the buffer groove through a buffer spring.

[0033] The buffer block 14 first abuts against the inside of the die-casting, and then moves downward through the positioning block 13 to fit the inner wall of the die-casting. After the positioning block 13 abuts against the inner wall of the die-casting, the upper punch plate 3 will continue to move downward, and the displacement plate 10 compresses the spring. During the downward movement of the upper punch plate 3, the cutter head is driven to remove burrs and slag bags on the inner side and partial outer side of the die-casting.

[0034] A lower punch plate 5 is connected directly above the lower pressure plate 1 through a second buffer assembly. A positioning platform 6 for placing the die-casting is fixedly connected to the upper surface of the lower punch plate 5. The positioning platform 6 is provided with a groove for placing the die-casting. When the die-casting is placed on the positioning platform 6, the groove fits with the die-casting, driving the die-casting to be precisely positioned, thereby reducing the phenomenon of damage to the die-casting when removing burrs.

[0035] The upper punching plate 3 and the lower punching plate 1 are both fixedly connected with a limit column 21 for limiting the downward distance of the first cutter head 4. The limit column 21 can control the cutting distance of the first cutter head 4 and reduce the damage to the die casting when cutting.

[0036] The second buffer assembly includes: a plurality of second guide posts 15 and a plurality of second compression springs 16 arranged between the lower pressing plate 1 and the lower punching plate 5 . The lower pressing plate 1 is equipped with a limit bolt 17 , which passes through the lower pressing plate 1 and is fixedly connected to the lower punching plate 5 .

[0037] The second compression spring 16 drives the lower punching plate 5 to move upward, and the limit bolt 17 controls the upward distance of the lower punching plate 5. The lower punching plate 5 is fixedly connected with a plurality of receiving barrels 24 (such as Figure 6 As shown in the figure, the receiving barrel 24 extends to the lower surface of the lower pressing plate 1, and a receiving cavity is provided on the lower surface of the lower pressing plate 1. The burrs and slag bags after cutting flow down from the receiving barrel 24 to the receiving cavity, and a storage cabinet can also be generally provided in the receiving cavity to collect the waste.

[0038] The upper punch plate 3 and the lower punch plate 1 are both fixedly connected with a limit column 21 for limiting the downward distance of the first cutter head 4. The limit column 21 can well limit the downward distance of the positioning block 13, reduce the phenomenon that the positioning block 13 damages the die casting due to excessive downward movement, and improve the processing accuracy.

[0039] The lower punching plate 5 is fixedly connected with a plurality of positioning components, and the lower punching plate 1 and the upper punching plate 3 are both fixedly connected with a third cutter head 8 that cooperates with the positioning components.

[0040] The positioning assembly is mainly used to support the outer side of the die casting, and cooperate with the third cutter head 8 to clean the burrs and slag bags of the die casting.

[0041] The positioning assembly includes: two first drive cylinders 18 and a second drive cylinder 19, the second drive cylinder 19 is arranged between the two first drive cylinders 18, and the telescopic rods of the first drive cylinder 18 and the second drive cylinder 19 are fixedly connected with a slider 20, and the slider 20 supports the outer side of the die casting.

[0042] The slider 20 is driven by the first drive cylinder 18 and the second drive cylinder 19 to abut and fit against the outer wall of the die-casting. When the third cutter head 8 cooperates in cutting, the slider 20 supports the outer wall of the die-casting to improve the cutting effect and reduce deformation or damage of the die-casting during cutting.

[0043] The lower punching plate 5 is fixedly connected to a support plate 22 , and the support plate 22 is fixedly connected to an adjusting bolt 23 .

[0044] For better adjustment, an adjusting bolt 23 is provided on the supporting plate 22, so as to facilitate the adaptation of die castings of different heights (mainly the waste height of the die castings) and improve the overall adaptation effect.

[0045] The lower punch plate 5 is fixedly connected with a second cutter head 7 cooperating with the first cutter head 4. When the upper punch plate 3 is in the downward process, the first cutter head 4 cooperates with the second cutter head 7 to remove burrs and slag bags of the die castings well, thereby improving the removal effect.

[0046] like Figures 1 to 6 As shown, during operation, the technician places the die-casting on the positioning table 6, positions the die-casting under the action of the groove, and drives the slider 20 to abut and fit against the outer wall of the die-casting through the first driving cylinder 18 and the second driving cylinder 19.

[0047] The upper pressing plate 2 drives the upper punching plate 3 downward, passes through the buffer block 14 and abuts against the inside of the die casting, and then passes through the positioning block 13 and moves downward to fit the inner wall of the die casting, and the positioning block 13 is used to position the inner side of the die casting.

[0048] After the positioning block 13 abuts against the inner wall of the die-casting, the upper stamping plate 3 will continue to move downward, and the displacement plate 10 compresses the spring. When the positioning column contacts, the upper stamping plate 3 continues to move downward, driving the lower stamping plate 5 downward, and the third cutter head 8 fixed on the lower pressing plate 1 will cooperate with the slider 20 to remove burrs on the die-casting.

[0049] During the downward movement of the upper punch plate 3 , the first cutter head 4 , the second cutter head 7 and the third cutter head 8 are driven to remove burrs and slag bags on the inner side and part of the outer side of the die casting.

[0050] Therefore, various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
