Description

Technical Field

[0001] The invention relates to the technical field of alloy plate processing, in particular to a processing device for an alloy plate. Background Art

[0002] In the current metal processing field, especially for cutting thin alloy plates, wire cutting, laser cutting or punching are commonly used. These technologies have their own advantages, but they also have certain limitations. Although wire cutting and laser cutting can provide higher processing accuracy and cutting quality, the equipment cost is high, the operation and maintenance costs are expensive, and the cutting effect for some special alloy materials is not ideal. Punching, as a traditional processing method, has been widely used in industrial production due to its high efficiency and economy.

[0003] However, when using a punch press to punch thin alloy sheets, the punching knife presses down along the cross section of the thin alloy sheet, thereby cutting the sheet into two sections. In this process, when the punching knife presses down and contacts the sheet, it will exert a downward pressure on the sheet, which causes the sheet to bend downward at the cut, resulting in extrusion deformation. Although this phenomenon does not affect the overall flatness of the cut alloy sheet, the edge bending problem at the cut has an adverse effect on subsequent use. For example, in situations where high-precision assembly is required, this edge bending may affect the assembly quality, increase the correction process, reduce production efficiency, and may even result in unqualified products.

[0004] In order to solve the above problems, although some improvement measures have been proposed, such as adjusting the blanking parameters, optimizing the tool design, etc., these methods can only alleviate the problem of edge bending to a certain extent, but cannot solve it fundamentally.

[0010] When the third oil cylinder drives the pressure roller frame to move in the first direction, the fourth oil cylinder drives the pressure roller frame to move in the third direction and drives the pressure roller frame to move in the second direction through the second guide rail, so that the pressure roller rolls transversely and presses on the incision of the alloy plate.

At the same time, the third oil cylinder and the fourth oil cylinder work together to convert the downward pressing force of the pressure roller frame and the pressure roller into a horizontal rolling pressing. Through the structural design of the chain plate and the lower platen, the rolling force is transmitted downward and to the side at the same time, so that when the pressure roller rolls horizontally, the pressed lower platen body and the adjacent lower platens sequentially and continuously form different downward pressures on the alloy platen, which greatly improves the pressing and flattening effect of the incision of the alloy platen.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the implementation scheme.

[0033] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0034] Reference Figure 1-6 An alloy plate processing apparatus according to the present embodiment will be described.

[0035] like Figure 1 and Figure 2 As shown, the existing processing device for cutting thin alloy plates includes a cutting machine 1, a chassis 2 is provided on the top of the cutting section of the cutting machine 1, a first oil cylinder 3 is fixed on the chassis 2, a tool holder 4 is fixed on the output end of the first oil cylinder 3, both side walls of the tool holder 4 are flat, and a punching knife 5 is fixed on the tool holder 4.

[0036] On the basis of the above, a plurality of second oil cylinders 6 are fixed on the chassis 2, and a pressure plate 7 is fixed on the output end of the second oil cylinder 6, and the pressure plates 7 are arranged on both sides of the punching knife 5. The pressure plates 7 are vertically connected to the side wall surface of the tool holder 4 through the first guide rail 8. There are two pressure plates 7, which are arranged on both sides of the punching knife 5 and are driven by the second oil cylinder 6 to move vertically. After the punching knife 5 cuts the thin alloy steel plate, the second oil cylinder 6 drives the two pressure plates 7 to rise and fall on both sides of the punching knife 5, flattening the bent part of the alloy steel plate at the incision, thereby reducing the degree of bending of the incision. The first guide rail 8 is used to guide the downward pressing and upward movement of the pressure plate 7, so that the lifting process of the pressure plate 7 is in a vertical state.

[0037] Further, such as Figure 1 and Figure 2As shown, in a preferred embodiment, the interior of the pressing plate 7 is a cavity with an opening at the bottom, a third oil cylinder 9 is fixed in the cavity, a pressing roller frame 12 is provided at the output end of the third oil cylinder 9, the third oil cylinder 9 drives the pressing roller frame 12 to move in the first direction, and a pressing roller 13 is rotatably connected to the bottom of the pressing roller frame 12. The pressing roller 13 driven down by the third oil cylinder 9 is used to roll and press the bent portion at the cut of the alloy steel plate, thereby improving the flattening effect of the bent portion in the rolling and pressing state.

[0038] like Figure 2 As shown, the bottom of the inner cavity of the pressing plate 7 extends toward the punching knife 5 to form an extension portion, and the pressing roller frame 12 is located in the extension portion. The function of the extension portion is to make the bottom of the pressing plate 7 close to the punching knife 5, so that the bottom of the pressing plate 7 is closer to the cutting edge of the alloy steel plate, thereby increasing the pressing area of ​​the cutting edge of the alloy steel plate and making the cutting edge smoother.

[0039] Furthermore, a fourth oil cylinder 11 is fixed in the cavity, and a T-shaped connecting frame 10 is fixed to the output end of the fourth oil cylinder 11. The transverse part of the T-shaped connecting frame 10 is fixedly connected to the roller frame 12. The fourth oil cylinder 11 drives the roller frame 12 to move in the third direction, and the propulsion force of the fourth oil cylinder 11 is dispersed on the roller frame 12 through the transverse part of the T-shaped connecting frame 10. When the fourth oil cylinder 11 is working, it applies an oblique propulsion force to the roller frame 12, so that the roller 13 at the bottom of the roller frame 12 rolls on the surface of the cut edge of the alloy steel plate. A table 16 is fixed to the output end of the third oil cylinder 9, and the table 16 covers part of the surface of the roller frame 12, which can disperse the downward pressure applied by the third oil cylinder 9 to the roller frame 12 through the table 16 to avoid pressure concentration. In addition, the table 16 is slidably connected to the roller frame 12 through the second guide rail 17. When the fourth oil cylinder 11 applies an oblique propulsion force to the roller frame 12, the roller frame 12 moves along the second direction on the second guide rail 17 to enable the roller 13 to roll on the surface of the cut edge of the alloy steel plate.

[0040] Among them, when the third oil cylinder 9 drives the pressure roller frame 12 to move in the first direction, the fourth oil cylinder 11 drives the pressure roller frame 12 to move in the third direction, and drives the pressure roller frame 12 to move in the second direction through the second guide rail 17, so that the pressure roller 13 rolls and presses horizontally on the incision of the alloy plate, and converts the downward pressing force into horizontal rolling pressing, thereby improving the pressing and flattening effect of the incision of the alloy plate.

[0041] The inner wall surface of the extension portion is obliquely provided with a slide groove 19, and a guide roller 18 matching the slide groove 19 is provided on the back of the roller frame 12. When the fourth oil cylinder 11 is working and applies an oblique propulsion force to the roller frame 12, the guide roller 18 on the back of the roller frame 12 moves in the oblique slide groove 19 to limit the moving direction of the guide roller frame 12. The opening direction of the slide groove 19 is horizontal to the setting direction of the fourth oil cylinder 11, so as to ensure that the propulsion direction of the fourth oil cylinder 11 is the same as the moving direction of the roller frame 12.

[0042] The positional relationship among the first direction, the second direction and the third direction is described as follows: the second direction is aligned with the horizontal line, the first direction and the second direction are perpendicular to each other, and the third direction is inclined relative to the first direction and the second direction.

[0043] In a preferred embodiment, Figure 2 and Figure 5 As shown, an auxiliary displacement component is provided on the outer side of the pressure plate 7 close to the blade of the punching knife 5 to move the cut alloy steel plate outward so that the cut alloy steel plate is away from the blade of the punching knife 5, so that the pressure plate 7 at this position can be pressed on the incision of the alloy plate after being pressed down, thereby ensuring the accuracy of pressing.

[0044] Specifically, the auxiliary displacement assembly includes a box 15, a vertically arranged strip groove is formed on the side wall of the box 15, a flange 20 is formed in the strip groove, a roller 22 is formed in the flange 20, a motor 21 for driving the roller 22 to rotate is formed on the flange 20, and a spring 23 connected to the box 15 and the flange 20 at both ends is formed in the strip groove. The spring 23 pushes the flange 20 and the assembly (roller 22 and motor 21) mounted thereon to descend in the strip groove, so that the roller 22 contacts the surface of the cut alloy sheet, and the motor 21 drives the roller 22 to rotate clockwise at a certain angle, and the friction between the roller 22 and the alloy sheet drives the cut alloy sheet to move to one side, away from the blade of the punching knife 5 and below the pressing plate 7 at this position. It should be noted that this process is performed after the second oil cylinder 6 is pressed down and before the third oil cylinder 9 is pressed down. After the second oil cylinder 6 drives the pressing plate 7 to rise, the auxiliary displacement assembly moves away from the thin alloy steel plate, so that the thin alloy steel plate with the cut flattened can be output normally.

[0045] Further, such as Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment, a lower pressing plate 14 is hinged at the opening at the bottom of the cavity, and the lower pressing plate 14 covers the rolling area of ​​the pressing roller 13. When the second oil cylinder 6 drives the pressing plate 7 to press down, the lower pressing plate 14 first contacts the cut of the thin alloy steel plate to perform the first pressing and flattening process.

[0046] Specifically, the lower pressing plate 14 includes a plurality of mutually hinged chain plates 141 and a plurality of lower platforms 143, each lower platform 143 is arranged in one-to-one correspondence with each chain plate 141, and a plurality of lower platforms 143 are arranged correspondingly at the bottom of each chain plate 141. A pressing platform 142 is fixed to the bottom of the chain plate 141; each lower platform 143 is hinged to the corresponding chain plate 141 through a beam 144. During implementation, the pressing roller 13 rolls and presses on the chain plate 141 in a transverse manner, and then transmits the pressing force to the lower platform 143 through the pressing platform 142, and the lower platform 143 contacts the surface of the alloy plate to flatten the alloy plate.

[0047] Each lower platen 143 has a first overlap surface 143a and a second overlap surface 143b on both sides, and the first overlap surface 143a and the second overlap surface 143b are both inclined slopes. Among them, the second overlap surface 143b overlaps the first overlap surface 143a of the adjacent lower platen 143, so that the lower platen 143 is pressed on the lower platen 143 on the adjacent side, and when the chain plate 141 is subjected to the rolling force of the pressure roller 13, it is transmitted to the corresponding lower platen 143, and the pressing force is transmitted to the adjacent lower platen 143 through the overlap of the second overlap surface 143b and the first overlap surface 143a. Multiple lower plates 143 overlap and combine to transmit the rolling force downward and to the side at the same time. When the pressure roller 13 rolls horizontally, the pressed lower platen 143 body and the adjacent lower platen 143 sequentially and continuously form different downward pressures on the alloy plate.

[0048] Specifically, the two adjacent lower platens 143 are respectively the main force-bearing body (the lower platen 143 in contact with the pressure roller 13) and the auxiliary force-bearing body (the lower platen 143 that is pressed), and there is an auxiliary force-bearing body between the two adjacent main force-bearing bodies. At this time, when the pressure roller 13 rolls horizontally, the downward pressure is first applied to the main force-bearing body, and the pressing force is concentrated on the main force-bearing body. When the auxiliary force-bearing body is pressed, the pressing force is applied to the alloy steel plate to form a pre-pressing of this place; when the pressure roller 13 rolls horizontally, the pressure roller 13 rotates to the auxiliary force-bearing body, and at this time the auxiliary force-bearing body is transformed into the main force-bearing body, and the surface of the alloy steel plate that has been pre-pressed is pressed; and the main force-bearing body in the previous step is transformed into the auxiliary force-bearing body, which is pressed by the main force-bearing body in this step, and the pressing force is applied to the alloy steel plate to form a re-pressing of this place. In general, the surface of the alloy steel plate is subjected to two rolling pressing forces respectively.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
