Description

Technical Field

[0001] The present invention relates to a rolling guide plate for preventing the lateral bending of rolled parts during the rolling of J-type forklift mast. Background Art

[0002] During the rolling of J-type forklift mast, due to the asymmetry of the product cross-section and uneven metal distribution at various parts, it is impossible to make the reduction coefficients at all parts exactly the same. After the finished product hole is rolled, it bends to one side. The traditional guide plate installed close to the rolled part can prevent side bending but will scratch the rolled part. If the distance of installing the anti-scratch wheel at the tail of the guide plate is too far, it will cause an acute bend at the head of the product, which cannot be saved and will affect the product quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an anti-side bending guide plate for rolling J-type forklift mast that can prevent the lateral bending of rolled parts.

[0004] The above object is achieved as follows: It includes a guide plate body. A rectangular window is opened at the front of the guide plate body. An anti-scratch wheel is arranged in the rectangular window at the front of the guide plate body. The anti-scratch wheel is installed at the front end of an anti-scratch wheel bracket through a shaft, and the anti-scratch wheel bracket is located outside the guide plate body;

[0005] Three grooves arranged vertically are provided in the guide plate body behind the rectangular window. The openings of the three grooves are all located on the outer side surface of the guide plate body. The three grooves are respectively an upper groove, a middle groove, and a lower groove;

[0006] A longitudinal first through hole is opened on the guide plate body between the lower groove and the middle groove. A longitudinal second through hole is opened on the guide plate body between the middle groove and the upper groove. A longitudinal third through hole is opened on the guide plate body above the upper groove. These through holes are on a straight line;

[0007] A connecting block is arranged in the middle groove. The connecting block is provided with non-intersecting transverse through holes and longitudinal through holes. There is an upper connecting seat above the connecting block and a lower connecting seat below the connecting block. Longitudinal through holes are provided on both the upper connecting seat and the lower connecting seat. The upper connecting seat is located in the upper groove and the lower connecting seat is located in the lower groove. After the first pin shaft extends into the third through hole of the guide plate body and then successively extends into the longitudinal through hole of the upper connecting seat, the second through hole of the guide plate body, the longitudinal through hole of the connecting block, the third through hole of the guide plate body, and the longitudinal through hole of the lower connecting seat, the upper connecting seat, the connecting block, and the lower connecting seat are connected in series. The lower end of the first pin shaft is located in the lower groove;

[0008] In the middle of one side of the anti-scratch wheel bracket facing the guide plate body, two connecting ears are welded. The two connecting ears on the anti-scratch wheel bracket extend into the middle groove of the guide plate body, and the two connecting ears are respectively located on the front side and the rear side of the connecting block. The two connecting ears and the connecting block are connected by a second pin shaft, that is, the second pin shaft penetrates into the holes of the two connecting ears and the horizontal through hole of the connecting block to connect the anti-scratch wheel bracket and the connecting block together.

[0009] There are two long holes, one above and one below, on the anti-scratch wheel bracket. An upper bolt extending outward is connected to the upper connecting seat, and a lower bolt extending outward is connected to the lower connecting seat. The bolts on the two connecting seats respectively extend out from the two long holes of the anti-scratch wheel bracket and are screwed with nuts. After the nuts are tightened, the slope of the anti-scratch wheel is fixed.

[0010] A set screw is installed at the rear of the anti-scratch wheel bracket, and the inner end of the set screw abuts against the guide plate body.

[0011] The advantages of the present invention are as follows: Since the slope of the anti-scratch wheel is adjustable, it can be perfectly matched with the slope of the outer edge of the rolled piece, and it will not cause indentation damage to the rolled piece. Since the protruding part of the anti-scratch wheel is adjustable, that is, after the anti-scratch wheel is worn and repaired, it can continue to be used through adjustment, improving the service life of the anti-scratch wheel.

[0019] The following Figures 1-7 further describes the present invention;

[0020] It includes a guide plate body 1. A rectangular window 11 is opened at the front of the guide plate body. An anti-scratch wheel 2 is arranged in the rectangular window at the front of the guide plate body. The anti-scratch wheel is installed at the front end of an anti-scratch wheel bracket 3 through a shaft, and the anti-scratch wheel bracket is located outside the guide plate body;

[0021] Inside the guide plate body behind the rectangular window, there are three grooves arranged vertically. The openings of the three grooves are all located on the outer side surface of the guide plate body. The three grooves are respectively an upper groove 12, a middle groove 13, and a lower groove 14;

[0022] On the guide plate body between the lower groove and the middle groove, a longitudinal first through hole 15 is opened. On the guide plate body between the middle groove and the upper groove, a longitudinal second through hole 16 is opened. On the guide plate body above the upper groove, a longitudinal third through hole 17 is opened. These through holes are on a straight line.

[0023] Inside the middle groove, there is a connecting block 4. The connecting block is provided with non-intersecting transverse through holes and longitudinal through holes. Above the connecting block, there is an upper connecting seat 5. Below the connecting block, there is a lower connecting seat 6. The upper connecting seat and the lower connecting seat are both provided with longitudinal through holes. Among them, the upper connecting seat is located in the upper groove, and the lower connecting seat is located in the lower groove. After a first pin shaft 7 extends into the guide plate body from the third through hole and then successively extends into the longitudinal through hole of the upper connecting seat, the second through hole of the guide plate body, the longitudinal through hole of the connecting block, the third through hole of the guide plate body, and the longitudinal through hole of the lower connecting seat, the upper connecting seat, the connecting block, and the lower connecting seat are connected in series. The lower end of the first pin shaft is located in the lower groove.

[0024] In the middle of the side of the anti-scratch wheel bracket 3 facing the guide plate body, two connecting ears 31 are welded. The two connecting ears on the anti-scratch wheel bracket extend into the middle groove of the guide plate body, and the two connecting ears are respectively located on the front side and the rear side of the connecting block. The two connecting ears and the connecting block are connected by a second pin shaft 8, that is, the second pin shaft penetrates into the holes of the two connecting ears and the transverse through hole of the connecting block to connect the anti-scratch wheel bracket and the connecting block together.

[0025] There are two long holes 32 arranged vertically on the anti-scratch wheel bracket. An upper bolt 51 extending outward is connected to the upper connecting seat 5. A lower bolt 61 extending outward is connected to the lower connecting seat 6. The bolts on the two connecting seats respectively extend out from the two long holes 32 of the anti-scratch wheel bracket and are screwed with nuts. After the nuts are tightened, the slope of the anti-scratch wheel is fixed.

[0026] A set screw 9 is installed at the rear of the anti-scratch wheel bracket. The inner end of the set screw abuts against the guide plate body.

[0027] By adjusting two nuts, one loose and one tight, the guide wheel bracket can be rotated around the second pin shaft, so as to adjust the inclination of the anti-scratch wheel. By adjusting the setscrew at the tail, the anti-scratch wheel bracket can be rotated around the first pin shaft to adjust the protrusion of the guide wheel, so as to achieve perfect contact between the anti-scratch wheel and the outer contour of the rolled piece.

[0028] The anti-scratch wheel should be installed as close as possible to the rolling roll inward, that is, the distance from the rolled piece leaving the rolling roll to contacting the anti-scratch wheel is very short, so as to avoid the influence of the side bending of the rolled piece on the later finishing.

[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
