Description

Technical Field

[0001] This utility model relates to the field of forging production and processing technology, specifically to a cutting device for forgings. Background Technology

[0002] Forgings are workpieces or blanks obtained by forging and deforming metal billets. Forgings themselves have significant advantages such as high strength, high toughness, and wear resistance. Therefore, forgings are needed in warehousing and logistics equipment. In the process of mass production, forgings need to be cut into several suitable equidistant forgings using a cutting device.

[0003] Some forging cutting devices can only perform fixed cutting on a single long forging at a time, resulting in low work efficiency during mass production. Therefore, they do not meet the existing requirements. In response, we have proposed a cutting device for forgings. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for forgings, in order to solve the problem mentioned in the background art that some forging cutting devices can only perform fixed cutting on a single long forging at a time, resulting in low work efficiency in mass production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for forgings, comprising a worktable, two fixed seats fixedly mounted on the upper end of the worktable, symmetrical placement slots opened on both sides of the interior of the two fixed seats, a driving cavity being connected through the placement slots on both sides and inside the fixed seats, clamping blocks extending into the placement slots being slidably connected on both sides inside the driving cavity, one of the fixed seats being fixedly mounted on one side of the upper end of the worktable, a connecting frame being slidably connected to the outer surface of the upper end of the supporting frame, a cutting blade being driven and connected to the bottom end of the connecting frame by a second motor, a cutting groove being opened on one side of the upper end of the worktable, and one end of the cutting blade extending through into the interior of the cutting groove.

[0006] Preferably, a shaft is rotatably connected to the middle of the drive cavity via a rotating shaft, a cam is fixedly connected to the outer surface of the shaft, and connecting rods are hinged to the upper parts of the protrusions at both ends of the cam, and the connecting rods are arranged in an arc shape.

[0007] Preferably, the ends of the connecting rods on both sides away from the cam are hinged to the bottom ends of the two clamping blocks that are close to each other, and a first spring is connected between the two sides of the ends of the two clamping blocks that are close to each other.

[0008] Preferably, the upper end of the shaft extends through to the top of the fixed seat and is fixedly connected to a handle. A fixed block is fixedly connected to one side of the handle and at the upper end of the fixed seat. The fixed block has a movable cavity inside.

[0009] Preferably, a limiting rod is movably connected inside the movable cavity, extending through the movable cavity and to the outside of the fixed block. A limiting plate that is slidably connected to the outer surface of the limiting rod at one end inside the movable cavity is fixedly connected to the limiting plate. A second spring is fixedly connected between one side of the limiting plate and one side of the inner wall of the movable cavity, and the second spring is wound around the outer surface of the limiting rod.

[0010] Preferably, the outer surface of the handle is provided with a plurality of limiting grooves at equal intervals, and the limiting rod extends through to one end of the fixed block and is inserted into the corresponding limiting groove.

[0011] Preferably, the top of the support frame has a groove, and a threaded rod is connected to the inside of the groove via a first motor. The upper end of the connecting frame is fixedly connected to a connecting block that is slidably connected to the groove and threadedly connected to the outer surface of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model involves inserting two long forgings into placement slots on both sides of a fixed base. Rotating the handle drives the shaft to rotate, which in turn drives the cam to rotate. The cam's protruding ends are hinged to one end of a connecting rod, causing the ends of the connecting rods on both sides to push the clamping blocks on both sides towards the opposite side until the clamping blocks engage with the inner wall of the placement slot to hold the long forgings. This simultaneously fixes the two long forgings to the upper end of the worktable. Then, starting the first motor drives the threaded rod to rotate. As the threaded rod rotates, the threaded rod causes the connecting block on the outer surface to slide along the inside of the groove, and also causes the connecting frame equipped with the cutting blade to move horizontally. At this point, starting the second motor drives the cutting blade to rotate, thus synchronously cutting the two long forgings through the movement of the cutting blade, improving work efficiency.

[0014] 2. This utility model, by pulling the limiting rod, causes the limiting rod to drive the limiting plate to compress the second spring, thereby causing one end of the limiting rod to disengage from the current limiting groove and move into the interior of the movable cavity, thus releasing the limitation on the rotating handle. Then, by releasing the pulling of the limiting rod, the second spring releases its elastic force, thereby pushing one end of the limiting rod through and extending to the outside of the fixed block, and inserting it into the corresponding limiting groove on the outside of the rotating handle, thereby limiting and fixing the rotating handle, preventing the rotating handle from rotating on its own, which would cause the clamping block to move and cause unstable clamping.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 The present invention provides an embodiment of a cutting device for forgings, comprising a worktable 1, two fixed seats 2 fixedly mounted on the upper end of the worktable 1, symmetrical placement grooves 201 opened on both sides of the interior of the two fixed seats 2, a driving cavity 202 connected through the placement grooves 201 on both sides and located inside the fixed seat 2, clamping blocks 13 extending into the placement grooves 201 slidably connected on both sides inside the driving cavity 202, and one side of one of the fixed seats 2 fixedly mounted on the upper end of the worktable 1, a support frame 3 fixedly mounted on one side of the fixed seat 2 and located on the upper end of the worktable 1, a connecting frame 6 slidably connected to the outer surface of the upper end of the support frame 3, a cutting blade 9 driven and connected to the bottom end of the connecting frame 6 by a second motor 8, a cutting groove 101 opened on one side of the upper end of the worktable 1, and one end of the cutting blade 9 extending through into the interior of the cutting groove 101.

[0022] Inside the drive cavity 202, a shaft 10 is rotatably connected to the middle via a rotating shaft. A cam 11 is fixedly connected to the outer surface of the shaft 10. Connecting rods 12 are hinged to the upper part of the protrusions at both ends of the cam 11, and the connecting rods 12 are arranged in an arc shape. The ends of the connecting rods 12 away from the cam 11 are hinged to the bottom ends of the two clamping blocks 13 that are close to each other. A first spring 14 is connected between the two sides of the two clamping blocks 13 that are close to each other.

[0023] By inserting the two long forgings into the placement slots 201 on both sides of the fixed seat 2, and then rotating the handle 15 to drive the shaft 10 to rotate, the shaft 10 rotates at the same time, and the cam 11 rotates. Then, through the hinge of the protruding ends on both sides of the cam 11 to one end of the connecting rod 12, the ends of the connecting rods 12 on both sides push the clamping blocks 13 on both sides to move towards the side that is far apart from each other, until the clamping blocks 13 cooperate with the inner side wall of the placement slot 201 to clamp the long forgings, thereby fixing the two long forgings simultaneously on the upper end of the worktable 1.

[0024] The upper end of the shaft 10 extends through to the top of the fixed base 2 and is fixedly connected to a handle 15. A fixed block 16 is fixedly connected to one side of the handle 15 and the upper end of the fixed base 2. The fixed block 16 has a movable cavity 1601 inside. A limiting rod 17 is movably connected inside the movable cavity 1601 and extends through the movable cavity 1601 to the outside of the fixed block 16. A limiting plate 18 is slidably connected to the movable cavity 1601 on the outer surface of one end of the limiting rod 17 inside the movable cavity 1601. A second spring 19 is fixedly connected between one side of the limiting plate 18 and one side of the inner wall of the movable cavity 1601. The second spring 19 is wrapped around the outer surface of the limiting rod 17. A number of limiting grooves 1501 are equally spaced on the outer surface of the handle 15. The end of the limiting rod 17 that extends through to the outside of the fixed block 16 is inserted into the corresponding limiting groove 1501.

[0025] By pulling the limiting rod 17, the limiting rod 17 causes the limiting plate 18 to compress the second spring 19, thereby causing one end of the limiting rod 17 to disengage from the current limiting groove 1501 and move into the interior of the movable cavity 1601, thus releasing the limitation on the rotating handle 15. Then, the pulling of the limiting rod 17 is released, at which point the second spring 19 releases its elastic force, thereby pushing one end of the limiting rod 17 through and extending to the outside of the fixing block 16, and inserting it into the corresponding limiting groove 1501 on the outside of the rotating handle 15, thereby limiting and fixing the rotating handle 15 and preventing the rotating handle 15 from rotating on its own.

[0026] The top of the support frame 3 has a groove 301. The inside of the groove 301 is connected to a threaded rod 5 by a first motor 4. The upper end of the connecting frame 6 is fixedly connected to a connecting block 7 that is slidably connected to the groove 301 and threadedly connected to the outer surface of the threaded rod 5.

[0027] By starting the first motor 4 to drive the threaded rod 5 to rotate, the threaded rod 5 rotates and the thread drives the connecting block 7 on the outer surface to slide along the inside of the groove 301, and drives the connecting frame 6 equipped with the cutting blade 9 to move horizontally. At this time, the second motor 8 is started to drive the cutting blade 9 to rotate, so that the two long forgings are cut synchronously by the movement of the cutting blade 9.

[0028] When using the forging cutting device, two long forgings are inserted into the placement slots 201 on both sides of the fixed base 2, with the part to be cut positioned above the cutting slot 101. Then, the limiting rod 17 is pulled, causing the limiting rod 17 to drive the limiting plate 18 to compress the second spring 19. This causes one end of the limiting rod 17 to disengage from the current limiting slot 1501 and move into the interior of the movable cavity 1601, thereby releasing the limitation on the rotating handle 15. Then, the rotating handle 15 is rotated, causing the shaft 10 to rotate. Simultaneously, the shaft 10 rotates, causing the cam 11 to rotate. Then, through the hinge between the protruding ends on both sides of the cam 11 and one end of the connecting rod 12, the ends of the connecting rods 12 that are far apart from each other push the clamping blocks 13 on both sides to move towards the side that is far apart from each other until the clamping blocks 13 engage with the inner wall of the placement slot 201. The long forgings are clamped, thus fixing the two long forgings simultaneously to the upper end of the worktable 1. Then, the pull on the limiting rod 17 is released. At this time, the second spring 19 releases its elastic force, thereby pushing one end of the limiting rod 17 through and extending to the outside of the fixing block 16, and inserting it into the limiting groove 1501 corresponding to the outside of the rotating handle 15, thereby limiting and fixing the rotating handle 15 to prevent the rotating handle 15 from rotating on its own, which would cause the clamping block 13 to move and cause unstable clamping. After the two long forgings are fixed, the first motor 4 is started to drive the threaded rod 5 to rotate. At the same time, the threaded rod 5 drives the connecting block 7 on the outer surface to slide along the inside of the groove 301, and drives the connecting frame 6 with the cutting blade 9 to move horizontally. At this time, the second motor 8 is started to drive the cutting blade 9 to rotate, thereby cutting the two long forgings synchronously through the movement of the cutting blade 9, improving work efficiency.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
