Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of straight machine needle cutting devices, in particular to a straight machine needle cutting device. Background Art
[0002] During the production process of straight machine needles, the steel wire is first straightened by a rotary machine, then cut into specified lengths by a cutting machine, and then the steel wire is polished with a rotating rack to sharpen both ends of the wire to form steel needles. The punching pressure flattens and punches the middle part of the steel needle, and finally the steel needle is cut from the middle to obtain two straight machine needles.
[0003] After the existing straight needle cutting device punches and cuts the steel needle, the steel needles distributed in the steel needle groove are difficult to unload automatically. When the straight needle is pushed by the pushing device, due to the small structure of the straight needle, it is easy for the material in the steel needle groove to not be completely discharged, affecting the continuous operation of the straight needle cutting device.
[0004] For this purpose, we propose a straight needle cutting device. Utility Model Content
[0005] The utility model mainly solves the above technical problems and provides a straight needle cutting device.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a straight needle cutting device, comprising a conveying frame, wherein a plurality of groups of track rods are fixedly installed in the conveying frame, and a plurality of groups of track rods are provided with steel needle conveying assemblies, and the steel needle conveying assembly comprises a sliding frame with a hollow structure, and the sliding frame is slidably installed in the conveying frame, and a plurality of groups of steel needle placement grooves for placing straight needles are equidistantly provided on the top surface of the sliding frame, and a flip plate is provided on the inner bottom surface of the steel needle placement groove, and the flip plate is movably installed in the steel needle placement groove through an embedded rotating shaft, and a protrusion is provided at the free end of the flip plate, and the protrusion is distributed in the hollow structure in the sliding frame;
[0007] Multiple groups of track rods are provided with built-in block assemblies, and the built-in block assemblies include a first built-in block and a second built-in block. The first built-in block and the second built-in block are both fixedly installed on the multiple groups of track rods. The first built-in block and the second built-in block are spliced and fixed to each other. The top surface of the first built-in block is provided with multiple groups of makeshift grooves, and the top surface of the second built-in block is provided with multiple groups of rebound beads.
[0008] Preferably, a connecting block is fixedly mounted on the bottom surface of the sliding frame, and an electric push rod is provided on the connecting block for pushing the sliding frame to slide freely on the track rod.
[0009] Preferably, a cutting groove is provided on the top surface of the sliding frame, and the cutting groove and the steel needle placement groove are perpendicular to each other.
[0010] Preferably, a plurality of circular grooves are formed through the top surface of the sliding frame, and the rebound balls are movably installed in the circular grooves through spring columns.
[0011] Preferably, the plurality of groups of rebound beads are equidistantly distributed on the extension line of the clearance groove.
[0012] Preferably, a discharge platform is provided on the bottom surface of the conveyor frame at a position corresponding to the built-in block assembly.
[0013] Beneficial effects
[0014] The utility model provides a straight needle cutting device with the following beneficial effects:
[0015] (1) A straight needle cutting device, when cutting a steel part, the sliding frame carries the steel needle and slides to the side close to the built-in block assembly until the first built-in block is sleeved inside the sliding frame, and the paving groove is opened to avoid the protrusions distributed in the sliding frame. The first built-in block is sleeved inside the sliding frame to increase the bearing pressure of the sliding frame, so that the punching plate drives the tool to punch down and cut the steel needle on the steel needle conveying assembly. After the steel needle on the steel needle conveying assembly is cut, the sliding frame is controlled to continue to slide to the side close to the built-in block assembly until the second built-in block is sleeved in the sliding frame. After the second built-in block is completely sleeved into the sliding frame, the rebounding rebound ball squeezes the protrusion, so that the protrusion drives the flip plate to flip with the rotating shaft as the center. The flip plate will push the straight needle in the steel needle placement groove to slide down and discharge from both sides. The straight needle that has separated from the steel needle conveying assembly is discharged to both sides along the discharge table, achieving the effect of automatic unloading of the straight needle.
[0016] (2) In a straight needle cutting device, when a steel part is cut, the sliding frame slides with the steel needle toward the side close to the built-in block assembly until the first built-in block is sleeved inside the sliding frame. The opening of the clearance groove plays a role in avoiding the protrusions distributed in the sliding frame. The first built-in block is sleeved inside the sliding frame to increase the bearing pressure of the sliding frame, thereby achieving the effect of increasing the stamping force strength of the sliding frame and avoiding deformation of the sliding frame when the steel needle is stamped and cut.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0026] Embodiment: A straight machine needle cutting device, as Figures 1 - 3As shown, it includes a conveying rack 1. Inside the conveying rack 1, multiple groups of track rods 3 are fixedly installed. On the multiple groups of track rods 3, there is a steel needle conveying assembly 4. The steel needle conveying assembly 4 includes a sliding frame 401 with a hollow structure. A connecting block 402 is fixedly installed on the bottom surface of the sliding frame 401. The sliding frame 401 is slidably installed inside the conveying rack 1. An electric push rod 8 is provided on the connecting block 402. By pushing the electric push rod 8, the sliding frame 401 can freely slide on the track rod 3. On the top surface of the sliding frame 401, multiple groups of steel needle placement grooves 403 for placing straight needles are equidistantly opened. On the inner bottom surface of the steel needle placement groove 403, there is a turning plate 405. The turning plate 405 is embedded and movably installed on the inner bottom surface of the steel needle placement groove 403 through a rotating shaft. A convex block 406 is provided at the free end of the turning plate 405. The convex blocks 406 are distributed in the hollow structure inside the sliding frame 401;
[0027] As Figure 2 shown, a cutting groove 404 is opened on the top surface of the sliding frame 401. The cutting groove 404 and the steel needle placement groove 403 are perpendicularly distributed to each other. Before being cut, the straight needle is a steel needle with sharp ends at both ends. By cutting from the middle position of the steel needle, one steel needle is divided into two straight needles;
[0028] As Figures 1 - 3 shown, during operation, the steel needles are distributed in the steel needle placement grooves 403. By pushing the connecting block 402 to slide through the electric push rod 8, the connecting block 402 drives the sliding frame 401 to slide to the cutting area. Above the cutting area, there is a stamping plate 6, and a tool 7 with a structure adapted to the structure of the cutting groove 404 is provided on the bottom surface of the stamping plate 6. By controlling the tool 7 to stamp downward, the steel needles distributed on the sliding frame 401 are cut;
[0029] As Figure 4As shown in the figure, built-in block components 5 are provided on multiple sets of track rods 3. The built-in block components 5 include a first built-in block 501 and a second built-in block 502. Both the first built-in block 501 and the second built-in block 502 are fixedly installed on the multiple sets of track rods 3. The first built-in block 501 and the second built-in block 502 are spliced and fixed to each other. A plurality of relief grooves 503 are formed on the top surface of the first built-in block 501. A plurality of return beads 504 are provided on the top surface of the second built-in block 502. The return beads 504 are movably installed on the second built-in block 502 through spring columns. The plurality of return beads 504 are equidistantly distributed on the extension line of the relief grooves 503. When the steel piece is cut, the sliding frame 401 drives the steel needle to slide towards the side close to the built-in block component 5 until the first built-in block 501 is sleeved inside the sliding frame 401. The formed relief grooves 503 play an avoidance role for the bumps 406 distributed inside the sliding frame 401. The first built-in block 501 being sleeved inside the sliding frame 401 increases the bearing pressure of the sliding frame 401, facilitating the stamping plate 6 to drive the cutter 7 to punch downward to cut the steel needles on the steel needle conveying component 4. After the steel needles on the steel needle conveying component 4 are cut, the sliding frame 401 is controlled to continue sliding towards the side close to the built-in block component 5 until the second built-in block 502 is sleeved inside the sliding frame 401. After the second built-in block 502 is completely sleeved inside the sliding frame 401, the rebounding return beads 504 exert an extrusion effect on the bumps 406, causing the bumps 406 to drive the turning plate 405 to flip around the rotating shaft. The turning plate 405 will push the straight needles in the steel needle placement groove 403 to slide out from both sides. The bottom surface of the conveying rack 1 is provided with a discharge table 2 corresponding to the position of the built-in block component 5. The straight needles separated from the steel needle conveying component 4 slide out to both sides along the discharge table 2.
[0030] The working principle of the present utility model:
[0031] When the steel piece is cut, the sliding frame 401 drives the steel needle to slide towards the side close to the built-in block component 5 until the first built-in block 501 is sleeved inside the sliding frame 401. The formed relief grooves 503 play an avoidance role for the bumps 406 distributed inside the sliding frame 401. The first built-in block 501 being sleeved inside the sliding frame 401 increases the bearing pressure of the sliding frame 401, facilitating the stamping plate 6 to drive the cutter 7 to punch downward to cut the steel needles on the steel needle conveying component 4;
[0032] After the steel needles on the steel needle conveying component 4 are cut, the sliding frame 401 is controlled to continue sliding towards the side close to the built-in block component 5 until the second built-in block 502 is sleeved inside the sliding frame 401. After the second built-in block 502 is completely sleeved inside the sliding frame 401, the rebounding return beads 504 exert an extrusion effect on the bumps 406, causing the bumps 406 to drive the turning plate 405 to flip around the rotating shaft. The turning plate 405 will push the straight needles in the steel needle placement groove 403 to slide out from both sides. The straight needles separated from the steel needle conveying component 4 slide out to both sides along the discharge table 2.
