Description

Technical Field

[0001] This invention relates to the field of metal mold production equipment technology, specifically to a shearing device and its process for metal mold production. Background Technology

[0002] Metal molds are a common industrial processing tool used in the manufacture of various metal products. In the production and manufacturing process of metal molds, it is often necessary to first cut the metal plate used to prepare the metal mold into a suitable size to facilitate subsequent processing. At this time, a shearing device is required for the shearing operation.

[0003] Existing shearing devices (such as shearing machines) often use a straight-up-and-down shearing motion when shearing metal sheets. This method is commonly used for straight shearing. However, since metal molds often require metal sheets of different shapes, existing shearing devices lack mechanisms for adjusting and fixing the angle of the metal sheet when shearing it at an angle. Operators often have to manually adjust the angle of the metal sheet and then push it to the bottom of the shearing blade for shearing. This process can easily cause deviations in the shearing angle of the metal sheet and needs improvement. Summary of the Invention

A second connecting screw for fixing the position of the U-shaped frame is provided on the side wall of the front face of the U-shaped frame. An assembly plate is connected to the rear back of the second connecting screw. A first connecting screw that cooperates with the U-shaped frame to fix the position of the telescopic plate is installed on the rear back of the assembly plate.

[0011] Preferably, the auxiliary component includes a fixed frame fixed to the top of the rotating plate, a sliding block whose position is adjusted according to the tilt angle of the metal plate is provided in the fixed frame, an extension plate is provided at the top of the sliding block, a rotating rod is provided on the extension plate, and a guide plate for supporting the tilted part of the metal plate is installed on the rotating rod.

[0012] Preferably, the front end face of the sliding block is provided with an L-shaped connecting plate, and the L-shaped connecting plate is provided with a positioning screw for fixing the position of the sliding block.

[0013] Preferably, the top of the extension plate is provided with a sliding groove, and a bonding plate for locking the position of the rotating rod is provided in the sliding groove.

[0014] Preferably, a connecting spring is installed between the bonding plate and the inner wall of the sliding groove to push the bonding plate to move.

[0016] Preferably, the bottom inner wall of the positioning adjustment groove is provided with an anti-slip groove, and the bottom inner wall of the U-shaped frame is provided with an anti-slip slider that is adapted to the anti-slip groove.

[0017] Preferably, a mounting block is provided on the left side of the rotating plate, the mounting block is connected to the rotating plate by a rotating rod, and a rotating shaft is provided on the mounting block, the rotating shaft being mounted on the first translation plate.

[0018] Preferably, a square block is provided at the top of the rotating rod, and a limiting frame is movably fitted on the outer wall of the square block to restrict its rotation, and the limiting frame is connected to the mounting block and the rotating plate by means of a slot and a block.

[0019] Preferably, the rear back sides of the first translation plate and the second translation plate are connected to a stabilizing plate to ensure that the two move synchronously.

[0020] An operating procedure for a shearing device used in metal mold production includes the following steps:

[0021] Step 1: Place the metal plate on the operating table of the machine body. According to the drawings and data provided by the metal mold production, control the rotating plate to rotate and adjust the tilt angle through the rotating shaft. At this time, the telescopic plate extends synchronously and is always located in the adjustment and positioning groove of the second translation plate. After the angle adjustment is completed, control the U-shaped frame to slide and fit against the back side wall of the telescopic plate, and control the first connecting screw to rotate until it fits against the front side wall of the telescopic plate. Then connect the assembly plate through the second connecting screw to fix the angle of the rotating plate. Then, place one corner of the metal plate in the corner formed after the telescopic plate and the U-shaped frame are fitted together, and press the metal plate tightly against the rotating plate. Then, push it to move it under the shearing blade for oblique shaping and shearing with the left side lower and the right side higher.

[0022] Step 2: Rotate the rotating plate via the rotating shaft to adjust it to a perpendicular angle with the first translation plate and fix its position. Control the sliding block to slide and adjust its position within the fixed frame. At this time, only control the rotating rod and guide plate to rotate and adjust their tilt angle with the rotating plate and fix their positions. Then, attach the metal plate to the guide plate and make it contact the rotating plate. Push the rotating plate to move the metal plate to the underside of the shearing blade for cutting. This allows the metal plate to be adjusted to a shape that is higher on the left and lower on the right for cutting according to usage requirements.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention controls the rotating plate to rotate at an angle to the metal plate to be cut, and then attaches the metal plate to the rotating plate and supports the corner formed by the U-shaped frame and the telescopic plate. This not only allows the metal plate to be quickly adjusted to the required angle for cutting, but also avoids deviation during the movement of the metal plate.

[0025] By rotating the telescopic plate to fit against the inner wall of the positioning adjustment groove on the second translation plate and fixing its position, the guide plate can be rotated to adjust its tilt angle with the rotating plate and then fixed in position. The metal plate can then be attached to the guide plate. The rotating plate can then be pushed to move the metal plate to the underside of the shearing blade for cutting. This allows the metal plate to be adjusted to a left-high-right-low or left-low-right-high state for cutting according to usage requirements. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 10 This invention provides a technical solution: a shearing device and its process for metal mold production, comprising a machine body 1 made by a shearing machine. The shearing machine adopts existing technology such as the Q11 series hydraulic shearing machine, which is a common existing technology and will not be described in detail here. The front end of the machine body 1 is provided with an operating table for placing the metal plate to be sheared. An adjustment component 2 for adjusting the shearing angle of the metal plate is provided on the operating table 1. The adjustment component 2 includes a first translation plate 4 and a second translation plate 5. The back sides of the first translation plate 4 and the second translation plate 5 are connected together by welding to a stabilizing plate 6. The stabilizing plate 6 assembles the first translation plate 4 and the second translation plate 5 into a whole, and facilitates the simultaneous and stable translation movement of the first translation plate 4 and the second translation plate 5 when the entire adjustment component 2 is pushed to move later.

[0039] Two translation slots 3 are provided on the operating table of the machine body 1. The length, width and height of the first translation plate 4 and the second translation plate 5 are the same, and the width of the first translation plate 4 and the second translation plate 5 is the same as that of the two translation slots 3. The translation slots 3 extend from the top of the operating table of the machine body 1 to the left and right side walls of the machine body 1, and are located on the left and right sides of the path of the shearing blade on the machine body. The first translation plate 4 and the second translation plate 5 are placed in the translation slots 3 on the operating table of the machine body 1, so that the first translation plate 4 and the second translation plate 5 keep moving in a straight line. Through the cooperation of the translation slots 3 and the stabilizing plate 6, it is convenient to prevent the U-shaped frame composed of the first translation plate 4, the second translation plate 5 and the stabilizing plate 6 from deforming during the later process of moving the metal plate by the rotating plate 11, so as to avoid the deviation of the cutting angle of the metal plate due to the movement of the first translation plate 4 and the second translation plate 5.

[0040] The first translation plate 4 is provided with an angle adjustment component for adjusting the tilt angle of the auxiliary metal plate. The angle adjustment component includes a rotating shaft 7. The first translation plate 4 is provided with a mounting groove. The opening of the mounting groove is located on the right side of the first translation plate 4. The rotating shaft 7 is placed in the mounting groove. The inner wall of the bottom end of the mounting groove is provided with a circular groove with the same diameter as the rotating shaft 7. The top plate of the mounting groove is provided with a through hole with the same diameter as the rotating shaft 7. The bottom end of the rotating shaft 7 is inserted into the circular groove in the mounting groove, and the top end of the rotating shaft 7 extends to the top of the first translation plate 4 through the through hole in the mounting groove. A pointer is welded and installed on the outer wall of the rotating shaft 7 above the first translation plate 4.

[0041] An angle ruler is installed at the top of the first translation plate 4. The angle ruler is designed as a ring and the angle data is engraved inside the ring. The ring is placed around the rotating shaft 7 and the pointer and is fixedly installed at the top of the first translation plate 4 by welding. The rotating shaft 7 drives the pointer to rotate synchronously during rotation. By observing the rotation amplitude of the pointer and recording the different positions of the pointer when it stops on the angle ruler, the rotation amplitude of the rotating shaft 7 and the rotating plate 11 can be obtained. This makes it convenient to determine the tilt amplitude of the metal plate and whether it is the same as the required bevel angle size of the metal plate by the rotating shaft 7 and the pointer that follow the rotation of the rotating plate 11 when beveling the metal plate.

[0042] A mounting block 8 is welded and installed on the outer wall of the rotating shaft 7. A rotating plate 11 for adjusting the tilt angle of the metal plate is set on the right side of the mounting block 8. A rotating rod 9 is set between the rotating plate 11 and the mounting block 8. The left and right sides of the rotating rod 9 are rotatably connected to the mounting block 8 or the rotating plate 11 through rotating connecting rings. By controlling the rotation of the rotating rod 9, when an excessively thick metal plate is placed on the operating table of the machine body 1 and no angled shearing is required, the rotating plate 11 can be flipped by controlling the rotation of the rotating rod 9. At this time, the operator pushes the rotating plate 11 to the side of the metal plate furthest from the operating table to move the metal plate under the shearing blade for shearing. This increases the distance between the operator and the shearing blade during the shearing process and avoids the safety accident that may be caused by the operator pushing the heavy metal plate.

[0043] A square block is welded and installed on the top side wall of the rotating rod 9. A limiting frame 10 is set between the mounting block 8 and the rotating plate 11 to restrict the rotation of the rotating plate 11. The limiting frame 10 is U-shaped and the opening of the U-shaped limiting frame 10 faces downward. The width of the opening on the limiting frame 10 is the same as the width of the square block. A locking block is welded and installed on both the left and right side walls of the limiting frame 10. The top of the mounting block 8 and the rotating plate 11 are also provided with a locking groove that matches the locking block. After the limiting frame 10 is fitted onto the outer wall of the square block on the rotating rod 9, the locking block is simultaneously locked into the locking groove, which can restrict the rotation of the rotating plate 11 and prevent it from rotating itself when the angle of the metal plate is adjusted by using the rotating plate 11.

[0044] A telescopic plate 12 with adaptive adjustment position is provided on the right side of the rotating plate 11. The rotating plate 11 is a hollow plate, and an opening with the same length and width as the telescopic plate 12 is provided on the right side wall of the rotating plate 11. The telescopic plate 12 extends into the inner cavity of the rotating plate 11 through the opening, and the right inner wall of the rotating plate 11 and the left side of the telescopic plate 12 are connected by a spring. This allows the spring to push the telescopic plate 12 out or in the inner cavity of the rotating plate 11 when the rotating plate 11 is rotated to adjust its position, so that it can be positioned between the first connecting screw 14 and the U-shaped frame 13, which facilitates the subsequent fixing of the position of the telescopic plate 12 and the rotating plate 11.

[0045] The second translation plate 5 is provided with a positioning adjustment groove, in which an angle locking component for fixing the rotating plate 11 is provided. The angle locking component includes a U-shaped frame 13 that movably fits against the telescopic plate 12. An anti-slip groove is provided on the bottom inner wall of the positioning adjustment groove, and an anti-slip slider adapted to the anti-slip groove is provided on the bottom inner wall of the U-shaped frame 13. The anti-slip slider is fixedly connected to the bottom plate of the U-shaped frame 13 by welding to prevent the U-shaped frame 13 from detaching from the positioning adjustment groove. A threaded through hole is provided on the front side wall of the U-shaped frame 13, and a second connecting screw 16 for fixing the position of the U-shaped frame 13 is provided in the threaded through hole. A threaded hole is provided on the front side wall of the second translation plate 5. A first connecting screw 14 is provided in the perforation, which can cooperate with the U-shaped frame 13 to fix the position of the telescopic plate 12. The front end face of the first connecting screw 14 is provided with an assembly plate 15. The front end face of the assembly plate 15 is provided with a threaded groove with the same diameter as the second connecting screw 16. By passing the first connecting screw 14 through the front end side wall of the second translation plate 5 and extending it into the positioning adjustment groove, the position of the telescopic plate 12 is fixed in cooperation with the U-shaped frame 13. At this time, the second connecting screw 16 is controlled to pass through the front end side wall of the U-shaped frame 13 and connect with the assembly plate 15, so that the position of the U-shaped frame 13 can be fixed. That is, after the angle adjustment of the rotating plate 11 and the telescopic plate 12 is completed, their angle can be fixed.

[0046] The top of the rotating plate 11 is provided with an auxiliary component that provides an angled support effect. The auxiliary component includes a fixed frame 17 welded to the top of the rotating plate 11. A sliding block 18 with the same width dimension is slidably installed in the fixed frame 17. The height of the sliding block 18 is half the height of the inner frame of the fixed frame 17, that is, the sliding block 18 can extend out of the fixed frame 17. An L-shaped connecting plate 19 is welded to the front end of the part of the sliding block 18 that extends out of the fixed frame 17. Threaded through holes are provided on the front and rear sides of the L-shaped connecting plate 19. A positioning screw 20 is provided in the threaded through holes. After the sliding block 18 slides to the desired position in the fixed frame 17, the position of the sliding block 18 can be fixed by controlling the positioning screw 20 to pass through the L-shaped connecting plate 19 and fit tightly against the fixed frame 17.

[0047] An extension plate 21 is welded to the top of the sliding block 18. The extension plate 21 has through holes at both the top and bottom ends. A rotating rod 22 with the same diameter is placed in the through holes of the extension plate 21. A guide plate 23 for supporting the inclined part of the metal plate is welded to the outer wall of the rotating rod 22. The guide plate 23 is located below the extension plate 21. After the rotating plate 11 is rotated to the required angle by the rotating shaft 7 and the telescopic plate 12 is placed between the U-shaped frame 13 and the first connecting screw 14 for position fixation, one corner of the metal plate is placed in the corner formed by the telescopic plate 12 and the U-shaped frame 13, and the metal plate is pressed tightly against the rotating plate 11. It can then be pushed to move under the shearing blade for oblique shearing.

[0048] By rotating the telescopic plate 12 to fit against the inner wall of the front end face of the positioning adjustment groove on the second translation plate 5 and fixing its position, at this time, only the guide plate 23 is controlled to rotate to adjust its tilt angle with the rotating plate 11 and fix its position. The metal plate can then be attached to the guide plate 23. Then, the rotating plate 11 is pushed to move the metal plate to the underside of the shearing blade for cutting. This makes it convenient to adjust the metal plate to a left-high-right-low or left-low-right-high state for cutting according to the usage requirements.

[0049] The top of the extension plate 21 is provided with a sliding groove 24, in which a bonding plate 25 is slidably installed. The front side wall of the bonding plate 25 is connected to the inner wall of the front side of the sliding groove 24 by welding with a connecting spring 26. The bottom of the sliding groove 24 is provided with a T-shaped groove, in which a matching T-shaped slider is slidably installed. The top of the T-shaped slider is connected to the bonding plate 25 by adhesive. The back of the part of the bonding plate 25 that extends out of the inner cavity of the sliding groove 24 is set as an arc surface in the same circle as the rotating rod 22. The part of the rotating rod 22 above the extension plate 21 and the side of the bonding plate 25 near the rotating rod 22 are both provided with several meshing teeth. The bonding plate 25 is pushed to slide in the sliding groove 24 and adhere to the rotating rod 22 by the connecting spring 26. At this time, the teeth on both are meshed with each other, fixing the position of the rotating rod 22 and the guide plate 23.

[0050] An operating procedure for a shearing device used in metal mold production includes the following steps:

[0051] Step 1: Place the metal plate on the operating table on the machine body 1. According to the drawing data provided by the metal mold production, control the rotating plate 11 to rotate through the rotating shaft 7 to adjust the tilt angle. At this time, the telescopic plate 12 extends synchronously and is always located in the adjustment and positioning groove of the second translation plate 5. After the angle adjustment is completed, control the U-shaped frame 13 to slide and fit against the back side wall of the telescopic plate 12, and control the first connecting screw 14 to rotate until it fits against the front side wall of the telescopic plate 12. Then, connect the assembly plate 15 through the second connecting screw 16 to fix the angle of the rotating plate 11. Then, place one corner of the metal plate in the corner formed after the telescopic plate 12 and the U-shaped frame 13 are fitted together, and press the metal plate tightly against the rotating plate 11. Then, push it to move it under the shearing blade for left-low and right-high oblique shaping and shearing.

[0052] Step 2: Rotate the rotating plate 11 via the rotating shaft 7 to adjust it to a perpendicular angle with the first translation plate 4 and fix its position. Control the sliding block 18 to slide and adjust its position in the fixed frame 17. At this time, only control the rotating rod 22 and the guide plate 23 to rotate and adjust their tilt angle with the rotating plate 11 and fix their positions. Then, attach the metal plate to the guide plate 23 and contact the rotating plate 11. Then push the rotating plate 11 to move the metal plate to the underside of the shearing blade for cutting. This makes it convenient to adjust the metal plate to a shape that is higher on the left and lower on the right for cutting according to the usage requirements.
