Description

Technical Field

[0001] The invention relates to the technical field of casting processing equipment, and in particular to a burr removal device for metal die castings. Background Art

[0002] During the manufacturing process of metal die castings, some extra metal parts will be produced on the edge of the die castings due to various reasons such as loose mold closure, metal fluidity, mold wear, insufficient filling pressure or too fast filling speed. These parts are called "burrs" or "flash". The existence of burrs not only affects the appearance quality of the die castings, but also may reduce its mechanical properties and service life, and even cause the product to be unable to be used normally. Deburring of metal die castings is an important process in die casting processing.

[0003] Grinding is a common method for removing burrs from metal die-castings. When grinding and deburring metal die-castings, it is necessary to first position the metal die-castings, and then use the grinding tool to contact the burrs of the metal die-castings to achieve deburring. After the metal die-castings are positioned and clamped, the grinding tool can only deburr one side of the casting at a time. In order to achieve multi-sided deburring of castings, such as double-end flange pipe fittings, the castings need to be turned over after the burrs on one side are processed, and then clamped and positioned again before processing the second side. In existing production workshops, small castings are turned over manually, and large castings need to be turned over by staff using lifting equipment to turn them over and re-clamp and position them. The degree of manual participation is high and the processing efficiency is low. Summary of the invention

[0057] Furthermore, the first gear ring 73 and the second gear ring 74 are connected through a ring body 75, the inner edge of the ring body 75 is fixedly connected to the first gear ring 73, the outer edge of the ring body 75 is connected to the second gear ring 74, and the second gear ring 74 is coaxially arranged with the first gear ring 73. Figure 8The contact surface between the ring body 75 and the second gear ring 74 is provided with a first limit block 751, one side of the first limit block 751 is an inclined surface, and the other side of the first limit block 751 is a vertical surface. An elastic body 752 is provided between the first limit block 751 and the ring body 75, and the elastic body 752 is used to connect the first limit block 751 and the ring body 75. A limit groove 741 is provided on the contact surface between the second gear ring 74 and the ring body 75, and the limit groove 741 is used to accommodate the first limit block 751. When the ring body 75 rotates relative to the second gear ring 74 in the third direction W3, the first limit block 751 is located inside the limit groove 741, and the ring body 75 and the second gear ring 74 rotate synchronously; when the ring body 75 rotates relative to the second gear ring 74 in the fourth direction W4, the first limit block 751 leaves the limit groove 741, and the ring body 75 rotates relative to the second gear ring 74, forming a unidirectional rotation connection between the second gear ring 74 and the first gear ring 73.

[0058] refer to Figure 5 The first bracket 21 is provided with a second working cylinder 10, which is horizontally arranged, and a second stopper 101 is arranged at the working end of the second working cylinder 10. The second working cylinder 10 makes the second stopper 101 contact with the connecting seat 76 or the first gear ring 73 by telescoping, so as to realize different driving modes to match the rotational movements of the flip cylinder 4 in different directions.

[0059] When the second limiting block 101 contacts the connecting seat 76, the connecting seat 76 is limited, and the first gear 71 can rotate with the second gear 72, the first gear ring 73 and the second gear ring 74 (at this time, the ring body 75 rotates in the third direction W3 relative to the second gear ring 74), and the second gear ring 74 rotates synchronously with the third gear 83 and the fourth gear 84, thereby driving the third gear ring 43 and the rotating cylinder 401 to rotate, thereby realizing the flipping action of the flip cylinder 4 in the vertical plane.

[0060] When the second stopper 101 contacts the first gear ring 73, the first gear ring 73 is limited, and the first gear 71 can rotate with the second gear 72, the second power shaft 721 and the rotating platform 8, thereby realizing the rotation of the flip cylinder 4 in the horizontal plane. The rotating platform 8 rotates 45° relative to the first bracket 21, and the fourth conveying platform 6 rotates 45° synchronously. The fourth conveying platform 6 can connect the third conveying platform 22 and the second conveying platform 19. The flipped casting 9 passes through the third conveying platform 22, the fourth conveying platform 6 and the second conveying platform 19 in sequence and returns to the first conveying platform 2 to process the second end surface.

[0061] It is worth mentioning that when the flip cylinder 4 rotates in the horizontal plane, the third power shaft 82, the third gear 83, the fourth gear 84 and the second ring gear 74 rotate synchronously. Due to the one-way rotation connection between the second ring gear 74 and the first ring gear 73, when the second ring gear 74 rotates (equivalent to the ring body 75 rotating in the fourth direction W4 relative to the second ring gear 74), the first limit block 751 leaves the limit groove 741, and the second ring gear 74 rotates asynchronously with the first ring gear 73.

[0062] Furthermore, the fourth conveyor platform 6 is also an automatic roller conveyor platform, on which a plurality of horizontally arranged second conveyor rollers 601 are arranged, the second conveyor rollers 601 are connected by a second synchronous belt, and the plurality of second conveyor rollers 601 rotate in the same direction to realize continuous conveyance of materials, and the first bracket 21 is provided with a fifth motor (not shown) for driving the second conveyor rollers 601 to rotate. The upper conveying surface of the first conveyor belt 3, the upper conveying surface of the second conveyor belt 5, the top of the first conveyor roller 201 of the first conveyor platform 2, and the top of the second conveyor roller 601 of the fourth conveyor platform 6 are in the same horizontal plane.

[0067] Step A3: After the first end surface of the casting 9 is polished, the first conveyor platform 2 continues to convey the casting 9 from the first direction W1, so that the casting 9 enters the upper conveying surface of the first conveyor belt 3, and the three first conveyor belts 3 support and convey the casting 9. The first conveyor belt 3 also conveys the casting 9 from the first direction W1. The casting 9 is conveyed between the first mounting plate 41 and the second mounting plate 42. The second clamping cylinder 421 is used to drive the second positioning block 422 to move, and the first clamping cylinder 411 is used to drive the first positioning block 412 to move. The casting 9 can be clamped between the first mounting plate 41 and the second mounting plate 42, and the second clamping assembly completes the clamping of the casting 9.

[0068] Step A4: Reference Fig. 9 , the first motor 18 rotates with the first gear 71, and the first gear 71 can rotate with the second gear 72, the first gear ring 73 and the second gear ring 74, and the second gear ring 74 rotates with the third gear 83 and the fourth gear 84, thereby driving the third gear ring 43 and the rotating cylinder 401 to rotate, so as to realize the flipping action of the flip cylinder 4 in the vertical plane, and the flip cylinder 4 flips 180°, and the second clamping assembly on the flip cylinder 4 moves from the first position to the second position. At this time, the first mounting plate 41 moves to the bottom of the second conveyor belt 5, and the second mounting plate 42 moves to the top of the second conveyor belt 5, and the casting 9 comes to the upper conveying surface of the second conveyor belt 5, and the second end surface of the casting 9 faces upward, and the casting 9 is flipped;

[0069] Step A5: Reference Fig.10 The second clamping assembly on the turning cylinder 4 releases the clamping of the casting 9, and the second conveyor belt 5 continues to convey the casting 9 in the first direction W1, and the casting 9 leaves between the first mounting plate 41 and the second mounting plate 42. Fig.11 , the first motor 18 drives the turning cylinder 4 to rotate, so that the second clamping assembly on the turning cylinder 4 is located at the top of the turning cylinder 4;

[0070] Step A6: The second working cylinder 10 moves with the second limit block 101, the second limit block 101 contacts the first gear ring 73, the first gear ring 73 is limited, the first motor 18 rotates with the first gear 71, the first gear 71 can rotate with the second gear 72, the second power shaft 721 and the rotating platform 8, thereby realizing the rotation of the turning cylinder 4 in the horizontal plane, the turning cylinder 4, the rotating platform 8 and the fourth conveying platform 6 rotate 45° relative to the first bracket 21, and the fourth conveying platform 6 connects the first conveyor belt 3 and the second conveyor belt 5;

[0071] Step A7: Reference Fig.11The first conveyor belt 3, the second conveyor belt 5, the first conveyor platform 2 and the fourth conveyor platform 6 convey the casting 9 in the second direction W2. The casting 9 can return to the first conveyor platform 2 from the second conveyor belt 5 through the fourth conveyor platform 6 and the first conveyor belt 3 in sequence. The first grinding tool deburrs the second end surface of the casting 9. After the burr treatment is completed, the casting 9 is unloaded from the first conveyor platform 2.

[0072] In summary, the metal die casting burr removal device in this embodiment 1 can realize the bidirectional transmission of the casting 9. The casting 9 is subjected to burr removal treatment on the first end face on the first conveying platform 2. After the casting 9 is turned over, it can continue to return to the first conveying platform 2 by reverse movement to perform burr removal treatment on the second end face, saving time and labor for manual turning. The two end faces of the casting 9 are deburred at the same station, and a single grinding tool can continuously process the two end faces of the casting 9 to maintain the operating efficiency of a single grinding tool. However, the metal die casting burr removal device can only process the castings 9 one by one, and is mainly used for processing small batches of castings 9.

The fifth conveyor platform 14 is an automatic roller conveyor platform, on which a plurality of horizontally arranged third conveyor rollers 1401 are arranged, and the third conveyor rollers 1401 are connected by a third synchronous belt. The plurality of third conveyor rollers 1401 rotate in the same direction to realize continuous conveyance of materials, and the fifth conveyor platform 14 is provided with an eighth motor (not shown) for driving the third conveyor rollers 1401 to rotate.

[0074] Furthermore, the fifth conveying platform 14 is provided with a second grinding tool for removing burrs from the casting 9 on the fifth conveying platform 14, and the structure of the second grinding tool is the same as that of the first grinding tool. A third clamping assembly 20 is also provided on the side of the fifth conveying platform 14, and the structure of the third clamping assembly 20 is the same as that of the first clamping assembly 13. The fifth conveying platform 14 is used to convey the casting 9, and after the third clamping assembly 20 limits the casting 9, the second grinding tool is used to remove burrs from the casting 9.

[0076] The working process of the metal die casting burr removal device in this embodiment is as follows:

[0077] Step B1: The casting 9 is placed on the first conveying roller 201 of the first conveying platform 2, with the first end surface of the casting 9 facing upward; at this time, the second clamping assembly on the turning cylinder 4 is in the first position, the second mounting plate 42 is located below the first conveying belt 3, the first mounting plate 41 is located above the first conveying belt 3, the conveying direction of the fourth conveying platform 6 is perpendicular to the conveying direction of the first conveying platform 2, and the second limit block 101 is in contact with the connecting seat 76;

[0078] Step B2: The first conveyor 2 conveys the casting 9 from the first direction W1. When the casting 9 passes through the first clamping assembly 13, the third clamping cylinder 131 drives the third positioning block 132 to move. The casting 9 can be clamped between the third positioning blocks 132 on both sides of the first conveyor 2. The first grinding tool performs a deburring process on the first end surface of the casting 9.

[0079] Step B3: After the first end surface of the casting 9 is polished, the first conveyor platform 2 continues to convey the casting 9 from the first direction W1, so that the casting 9 enters the upper conveying surface of the first conveyor belt 3, and the three first conveyor belts 3 support and convey the casting 9. The first conveyor belt 3 also conveys the casting 9 from the first direction W1. The casting 9 is conveyed between the first mounting plate 41 and the second mounting plate 42. The second clamping cylinder 421 is used to drive the second positioning block 422 to move, and the first clamping cylinder 411 is used to drive the first positioning block 412 to move.

[0081] Step B5: the second clamping assembly on the flipping cylinder 4 releases its clamping of the casting 9, and the second conveyor belt 5 continues to convey the casting 9 in the first direction W1. The casting 9 leaves between the first mounting plate 41 and the second mounting plate 42 and comes to the fifth conveyor platform 14. When the casting 9 passes through the third clamping assembly 20, the third clamping assembly 20 clamps the casting 9, and the second grinding tool deburrs the second end face of the casting 9. After the burr treatment is completed, the casting 9 is unloaded on the fifth conveyor platform 14.

[0082] The metal die-casting burr removal device in this embodiment can realize one-way conveyance of the casting 9. The casting 9 is deburred on the first end face on the first conveying platform 2. After the casting 9 is turned over, the second end face can be deburred on the fifth conveying platform 14. The two end faces of the casting 9 can be continuously deburred, and can be used for the processing of large quantities of castings 9.

When a large number of castings 9 are processed, the fifth conveyor 14 works, and the castings 9 are transported in one direction, so as to realize continuous and efficient processing of the castings 9. When a small number of castings 9 are processed, the fifth conveyor 14 does not work, and the castings 9 are transported in two directions. The burr removal processing of the two end faces of the castings 9 can be performed at the first conveyor 2, and a set of grinding tools can achieve the processing goals, thereby reducing the energy consumption of the device operation.
