Description

Technical Field

[0001] The utility model belongs to the technical field of casting equipment, and in particular relates to a device for seaming a seam of a roller die end cover. Background Art

[0002] The inner wall of the roller mold used before roller casting needs to be sprayed with paint, and the end cover of the roller mold needs to be molded with end cover molding material to isolate the direct contact between the molten iron and the roller mold. However, there is often a gap between the roller mold and the end covers on both sides, and the spray paint cannot be sprayed in, so it needs to be manually sewed by a dedicated person. In this sew method, the sew material only remains on the surface of the end cover seam and cannot penetrate into the gap. At the same time, the body of the person is inserted into the roller mold. Due to the high temperature inside the roller mold, the person cannot work for a long time, resulting in low sew efficiency and poor quality. Therefore, it is necessary to design and develop a new sew device to replace the original sew method. Summary of the invention

[0003] The utility model aims to provide a device that can replace the original seam-nourishing method, so that personnel can operate on the outside of the roller mold, ensure that the seam-nourishing material penetrates into the gap and is evenly distributed around the circumference, meet the process technology requirements, improve production efficiency, and solve the problems existing in the technical background.

[0004] The technical solution of the utility model is:

[0005] A roller die end cover seam nourishing device comprises a base plate and a bracket fixed on the base plate, a suspension is fixed on the bracket, the suspension comprises a support rod, the top of the support rod is connected to one end of a bald treasure cover-shaped crossbeam, a hopper is fixed on the top of the crossbeam away from one end of the support rod, a material nozzle is arranged below the outlet of the hopper, a slide plate assembled in a slide groove is arranged between the hopper and the material nozzle, a material leakage hole is arranged at one end of the slide plate, and an upper connecting rod is assembled at the other end, the upper connecting rod is assembled with a lower connecting rod, the lower connecting rod is fixed on a central axis, a horizontal axis is arranged at the bottom of the lower connecting rod, and a roller head is assembled on the horizontal axis; a handle is arranged in the middle of the lower connecting rod; the central axis passes through the two protruding ends below the crossbeam.

[0006] Furthermore, one end of the handle is connected to the lower connecting rod, and the other end is connected to an end of the central axis close to the supporting rod.

Detailed implementation mode

[0021] The following further illustrates the present utility model with reference to the accompanying drawings through examples.

[0022] The present utility model provides a device for caulking the end cover seam of a roll die. Refer to Figure 2 , which includes a base plate 2, a support 1 fixed on the base plate 2, and a suspension 3 fixed on the support 1.

[0023] The suspension 3 is fixed on the support 1 through a support rod 3-1.

[0024] Refer to Figure 1 , in order to facilitate the adjustment of the height of the suspension 3, 3-6 limit holes 18 are provided on the support rod 3-1, and bolts 17 and matching through holes are provided on the support 1. When adjusting the height, remove the bolt 17, select a limit hole 18 at an appropriate position to align with the bolt 17 and the matching through hole, then the bolt 17 passes through the through hole and the limit hole 18, and the bolt 17 is fixed by a nut to achieve height adjustment.

[0025] At the top of the support rod 3-1, one end of the cross beam 3-2 is connected. The support rod 3-1 and the cross beam 3-2 are divided in terms of function, and the two can be an integral structure. The cross beam 3-2 is in the shape of "冖", similar to a bald treasure cover.

[0026] The length of the cross beam 3-2 is greater than 400 mm to ensure the safe distance between the device and the roller die 19 and avoid the high-temperature hot gas overflowing from the roller die 19.

[0027] The main functional structures are arranged on the cross beam 3-2 in the shape of a bald treasure cover, such as Figure 1 shown as:

[0028] A hopper 4 is fixed at the top of the end of the cross beam 3-2 far from the support rod 3-1. A nozzle 16 is arranged below the outlet of the hopper 4, and the nozzle 16 penetrates and extends out of the cross beam 3-2; a slide plate 5 assembled in a chute 6 is arranged between the hopper 4 and the nozzle 16. One end of the slide plate 5 is provided with a material leakage hole 7, and the other end is assembled with an upper connecting rod 8. The upper connecting rod 8 is assembled with a lower connecting rod 9, and the lower connecting rod 9 is fixed on a central shaft 13.

[0029] A horizontal shaft 11 is arranged at the bottom of the lower connecting rod 9, and a roller head 10 is assembled on the horizontal shaft 11; a handle 14 is arranged in the middle of the lower connecting rod 9.

[0030] The central axis 13 passes through the two lower protruding ends of the cross beam 3-2.

[0031] One end of the handle 14 is connected to the lower connecting rod 9, and the other end is connected to one end of the central axis 13 close to the support rod 3-1, and the handle 14 and the lower connecting rod 9 are linked.

[0032] The central axis 13 ensures horizontality and ensures that the lower connecting rod 9 can rotate freely about the central axis 13.

[0033] The upper connecting rod 8 and the slide plate 5 are assembled with a pin shaft to ensure the free rotation of the upper connecting rod 8 and the horizontal free movement of the slide plate 5.

[0034] Likewise, the upper connecting rod 8 and the lower connecting rod 9 are pin-assembled to ensure free rotation of the upper connecting rod 8 and the lower connecting rod 9 .

[0035] The lower connecting rod 9, the upper connecting rod 8, the slide plate 5, and the central axis 13 constitute a connecting rod mechanism. The horizontal movement of the slide plate 5 can be controlled by rotating the handle 14 fixed on the lower connecting rod 9, and the raw materials in the hopper 4 can be released through the leakage hole 7. When the leakage hole 7 leaves the outlet of the hopper 4, the feeding is stopped.

[0036] The width of the leakage hole 7 is 10-12 mm, and the inner diameter of the nozzle 16 is 8-10 mm, ensuring that the width of the leakage hole 7 is ≥ the diameter of the nozzle 16.

[0037] The top of the support rod 3-1 is provided with a stop pin seat 3-3, into which a stop pin 15 is inserted. The stop pin 15 is L-shaped, with its short side inserted into the stop pin seat 3-3, and its long side rotates horizontally with the short side as the axis, and when it rotates to the side of the handle 14, the handle 14 can be placed on the stop pin 15.

[0038] The length of the leakage hole 7 arranged in the slide plate 5 is ≥150mm, and its position and length ensure: 1. When the handle 14 is locked by the stop pin 15 and the entire device is in an inactive state, the leakage hole 7 and the material nozzle 16 do not intersect at all, the slide plate 5 blocks the outlet of the hopper 4, and the nourishing seam material is not discharged at all; 2. When the stop pin 15 is removed and the device is used, when its roller head 10 contacts the roller die 19, the leakage hole 7 can completely cover the material nozzle 16 through the connecting rod mechanism, ensuring that the nourishing seam material is completely discharged.

[0039] The roller head 10 is cylindrical, and the side away from the lower connecting rod 9 is an arc surface 12, and the diameter of the arc surface 12 is 6-10mm, so as to ensure that it does not touch the roller die end cover 23 during operation, but the gap with the roller die end cover 23 is ≤1mm. The function of the arc surface 12 is to ensure that a transition arc is formed between the final compacted seam material and the roller die 19 and the end cover 23, so as to reduce the stress generated when the end of the roller casting solidifies and shrinks.

[0040] When the roller head 10 is tangent to the roller die 19 , the position of the sliding plate 5 can ensure that the leakage hole 7 completely covers the material nozzle 16 .

[0041] The roller head 10 can freely rotate 360° along the horizontal axis 11, and the radial surface roughness of the roller head 10 is ≥Ra25, which ensures that sufficient friction is generated.

[0042] During operation, the nozzle 16 of the hopper 4 is located at the top of the roller die end cover seam 25, exactly corresponding to the end cover seam 25, and the vertical height distance between the nozzle 16 and the roller die end cover seam 25 is ≤200 mm.

[0043] When the equipment is not working, lift the handle 14, rotate the stop pin 15 to the bottom of the handle 14, and then place the handle 14 on the stop pin 15. At this time, the handle 14 drives the lower connecting rod 9, the upper connecting rod 8, and the slide plate 5 to move, so that the leakage hole 7 leaves the outlet position of the hopper 4, and the hopper 4 and the nozzle 16 are in a cut-off state, and the raw materials in the hopper 4 will not leak out.

[0044] When using this utility model, refer to Figure 3-5 When in use, ensure that the bracket 1 is on the vertical center line of the roller mold 19 and parallel to the end surface of the roller mold 19, and ensure that the arc surface 12 of the roller head 10 corresponds to the end cover seam 25 of the roller mold.

[0045] The end cover seam 25 is located between the end cover 23 , the end cover molding material 24 and the end of the roller mold 19 .

[0046] Start the centrifuge 20, rotate it clockwise at a low speed of 15 rpm, remove the stop pin 15, and the operator holds the handle 14 and rotates it downward until the roller head 10 is tangent to the roller die 19. After applying pressure, friction is generated between the roller head 10 and the roller die 19, and the roller head 10 rotates clockwise under the action of the friction. At the same time, since the handle 14 is connected to the lower connecting rod 9, the lower connecting rod 9 also rotates counterclockwise along the central axis 13, driving the upper connecting rod 8 to rotate counterclockwise, and then driving the slide plate 5 to move to the left, the leakage hole 7 completely covers the hopper nozzle 16, and the sew material in the hopper 4 flows down through the nozzle 16 and falls vertically into the roller On the die gap 25, the arc surface 12 of the roller head 10 rotating clockwise is rolled into the gap. After the roller die rotates one circle, new seam material falls from the material nozzle 16 to cover the seam material that has been rolled into the gap by the arc surface 12 of the roller head 10, and is rolled again by the arc surface 12 of the roller head 10 rotating clockwise, rolling the two layers of seam material into a new depth. In this way, after multiple rotations of the roller die 19, when the seam material is rolled by the arc surface 12 of the roller head 10, it no longer continues to enter the roller die gap, and the outer surface of the end cover gap has been completely filled with the seam material, and the operation is stopped at this time.

[0047] Lift the handle 14 to drive the lower connecting rod 9 to rotate clockwise, so as to drive the upper connecting rod 8 to rotate clockwise, and then drive the slide plate 5 to move to the right, so that the leakage hole 7 and the nozzle 16 are completely staggered, and the sew material stops flowing out, and the stop pin 15 is rotated to the bottom of the handle 14, the slide plate 5 blocks the outlet of the hopper 4, and the nozzle 16 stops discharging material, thus completing the sew processing of the gap of the roller die end cover.
