Description

Technical Field

[0001] This invention relates to the field of screwdriver production equipment technology, specifically to a fixed-length cutting device for raw materials used in screwdriver manufacturing. Background Technology

[0002] Screwdrivers are among the most common and frequently used hand tools. Their shafts (i.e., the screwdriver bit and connecting rod) are typically made from round or hexagonal steel through multiple processes such as cold drawing, turning, heat treatment, and grinding. In the mass production process of screwdrivers, the first step is to cut the coiled or bundled metal round rods to the required length of the finished screwdriver shaft.

[0003] Existing screwdriver raw material length cutting equipment still has the following shortcomings in practical applications: First, traditional cutting equipment usually requires manual operation of the clamping mechanism or the use of independent cylinders or hydraulic cylinders to clamp and fix the round rod when cutting it. This fixing method requires additional control components and power sources, increasing equipment costs and system complexity. Moreover, there is a lack of timing linkage between the clamping and cutting actions. If the operation sequence is not correct, it is easy to cut without clamping or the clamping force not being released in time after cutting, which not only affects the cutting quality but also poses safety hazards. Second, traditional fixtures are mostly fixed-size V-blocks or arc-shaped pressure plates. When it is necessary to cut round rods of different diameters, the opening of the fixture must be manually adjusted or the corresponding clamping module must be replaced. The debugging process is time-consuming and labor-intensive. Especially in the production mode of small batch and multiple varieties, frequent model changes seriously restrict the flexibility of the production line. Third, during the cutting process, the high-speed rotating cutting blade generates a large radial impact force when it cuts into the round rod, causing the rod to vibrate violently near the cutting point. If the clamping force of ordinary fixtures is insufficient or the clamping point is too far from the cutting point, it will result in a skewed cut, a rough cross-section, and a large amount of burrs and flash, increasing the burden on subsequent finishing processes. Fourth, the feeding and cutting actions of traditional equipment are independent of each other, often using a separate feeding motor or manual pulling to achieve fixed-length feeding. This not only requires an additional drive and control system, but also the accuracy of the feeding length is greatly affected by manual operation, making it difficult to achieve a continuous cycle of "cutting completed - automatic feeding - re-cutting". In addition, the transmission mechanism of traditional cutting equipment often cannot use the lifting and lowering motion of the cutting head itself to drive the rotation of the feeding wheel, resulting in low automation and requiring frequent operator intervention. Summary of the Invention

[0004] (a) Technical problems to be solved This invention provides a fixed-length cutting device for raw materials used in screwdriver manufacturing, which solves the problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a fixed-length cutting device for raw materials used in screwdriver manufacturing, comprising a base plate, a cutting groove extending through the upper surface of the middle portion of the base plate, sleeves symmetrically arranged on both sides of the cutting groove, wherein the openings at both ends of the sleeves are radially arranged, and further comprising: a cutting mechanism fixedly installed on the upper surface of the base plate; and an equal-length conveying assembly simultaneously fixedly installed on the upper surface of the base plate and connected to the cutting mechanism; wherein the cutting mechanism includes a slide rod symmetrically fixedly connected to the upper surface of the base plate, a stabilizing frame fixedly installed on the top of the slide rod, a sliding frame slidably connected to the slide rod, and an electric cutting machine fixedly installed in the middle of the sliding frame, wherein the electric cutting machine is positioned opposite the cutting groove on the base plate, and a hydraulic device is externally connected to the top of the electric cutting machine.

[0006] According to one embodiment of the present invention, a sliding seat is elastically slidably sleeved on the bottom outer surface of the slide rod, and an elastic telescopic cylinder is fixedly installed on the upper surface of the sliding seat, wherein the elastic force of the elastic telescopic cylinder is less than the elastic force between the sliding seat and the slide rod; a mounting frame is symmetrically fixedly connected to the upper surface of the middle part of the base plate, the mounting frames are arranged in pairs, and there are two sets of mounting frames in total, and the inner end of the mounting frame is symmetrically fixedly connected to the outer surface of the two sleeves that are close to each other. At the same time, a fixed seat is slidably installed on the mounting frame, the fixed seat is composed of two parts, and the two fixed seats are respectively arranged on both sides of the mounting frame; a stabilizing rod is fixedly connected to the outer end of the mounting frame, the inner end of the stabilizing rod is fixedly connected to the outer surface of the sleeve, and the fixed seat is slidably connected to the stabilizing rod; a telescopic rod is also fixedly installed on the outer end of the mounting frame, the telescopic rod is sleeved on the stabilizing rod, wherein the output end of the telescopic rod is fixedly connected to the outer surface of the fixed seat, and an interface is reserved on the mounting frame, the internal cavity of the telescopic rod is connected to the internal cavity of the elastic telescopic cylinder through the reserved interface using a flexible hose.

[0007] According to one embodiment of the present invention, a limiting rod is rotatably mounted on the bottom surface of the base plate. The limiting rod is configured as a threaded rod, wherein the threads at both ends of the limiting rod are symmetrically arranged, and the bottoms of two fixing seats on the same sleeve are respectively threaded to the two ends of the limiting rod; a synchronizing rod is also fixedly mounted on the bottom outer surface of the fixing seat, wherein the synchronizing rod is configured as a U-shape, and the other end of the synchronizing rod is fixedly connected to the bottom of the fixing seat on another set of mounting brackets.

[0008] According to one embodiment of the present invention, the equal-length conveying assembly includes an upper slide block, which is elastically slidably sleeved on the top outer surface of the slide rod. A drive rod is rotatably connected to the middle upper surface of the upper slide block. The drive rod is configured as a threaded rod, and the top of the drive rod is threadedly connected to the stabilizer.

[0009] According to one embodiment of the present invention, rotating rings are rotatably connected to the upper surfaces of both ends of the stabilizer frame, and adapter rods are symmetrically rotatably connected to both ends of the stabilizer frame. The bottom of the adapter rods is rotatably connected to the upper surface of the base plate. An upper transmission belt is rotatably connected to the outer surface of the rotating rings, and the end of the upper transmission belt away from the rotating rings is rotatably connected to the outer surface of the adapter rods. A lower transmission belt is rotatably connected to the bottom outer surface of the adapter rods.

[0010] According to one embodiment of the present invention, the interior of the rotating ring is hollow, wherein a transition ring is rotatably connected to the inner wall of the rotating ring, and the transition ring is slidably connected to the drive rod; a first baffle is hinged to the outer surface of the transition ring by a torsion spring, and a second baffle is fixedly connected to the inner surface of the rotating ring, wherein both the first baffle and the second baffle are inclined.

[0011] According to one embodiment of the present invention, a loading frame is symmetrically fixedly connected to the upper edge surface of the base plate. The loading frame is U-shaped, wherein a slider is elastically slidably connected to the upper and lower sides of the loading frame, and a drive wheel is rotatably connected to the slider. The outer side of the drive wheel is a rubber surface, and the end of the lower transmission belt away from the adapter rod is rotatably connected to the central shaft of the drive wheel.

[0012] The round rods to be cut to equal length are inserted into the two sleeves. Then, the electric cutting machine is started, and driven by an external hydraulic device, it moves downwards along the slide bar. The electric cutting machine then completes the cutting of the round rod. As the electric cutting machine moves downwards, the sliding frame moves along the slide bar, gradually contacting and compressing the elastic telescopic cylinders on the lower slide seat. Initially, the reverse elastic force provided by the lower slide seat compresses the elastic telescopic cylinders, which then transmit their internal air pressure to the telescopic rods on the mounting frame. This causes the telescopic rods to expand along the stabilizing rods, thereby pushing the fixed seats on the mounting frame closer together. Finally, through the mutual pressing and cooperation of two sets of four fixed seats, the two ends of the round rod cutting section are pressed and fixed. As the electric cutting machine moves downward, the pressing force increases until it is completely fixed. At this time, the elastic telescopic cylinder can no longer retract, that is, the pressing force begins to brake the sliding seat to move down along the slide rod until the electric cutting machine completes the cutting of the round rod. After the cutting is completed, the electric cutting machine is driven to move upward, so that the entire sliding seat is reset first. After the sliding seat is reset, as the sliding frame continues to move upward, the elastic telescopic cylinder begins to expand and reset, thereby driving the fixed seat to move to the outer end of the mounting frame to release the fixation of the round rod.

[0013] (III) Beneficial Effects This invention provides a fixed-length cutting device for raw materials used in screwdriver manufacturing. It has the following advantages: (I) This screwdriver manufacturing raw material fixed-length cutting equipment automatically squeezes and fixes the round rod during cutting, avoiding the drawbacks of traditional cutting equipment that requires frequent equipment adjustment for fixing. Moreover, it can automatically release the fixing effect after cutting, which greatly improves the productivity of the equipment and speeds up the production. Furthermore, due to the elastic fixing, this equipment can automatically adapt to the cutting production of round rods of different diameters, further improving the applicability of this equipment and reducing production costs.

[0014] (ii) The screwdriver manufacturing raw material fixed length cutting equipment can also limit the two ends of the round rod in a small range during cutting by setting two sleeves, which restricts the vibration of the round rod and greatly reduces the problem of low cutting accuracy caused by the vibration of the round rod during the cutting process caused by the operation of traditional cutting equipment. At the same time, it also reduces the possibility of burrs and flash.

[0015] (III) The fixed-length cutting equipment for raw materials used in the production of this screwdriver, after the sliding frame moves upward and the fixed seat resets after cutting, gradually contacts and squeezes the upper sliding seat as it continues to move upward, causing the upper sliding seat to move upward along the sliding rod, thereby driving the drive rod to move upward. Because the drive rod is a threaded rod and the top of the drive rod is threadedly connected to the stabilizer, the drive rod will rotate as it moves upward with the upper sliding seat, thereby driving the adapter ring to rotate counterclockwise and move upward. When the adapter ring rotates counterclockwise, it will drive the rotating ring with the second baffle to rotate through the first baffle, and then drive the adapter rod to rotate counterclockwise through the upper transmission belt, and finally drive the drive wheel to rotate counterclockwise through the lower transmission belt at the bottom, thus starting the rolling motion by the clamping of the two drive wheels. The effect drives the round rod to move forward automatically, while simultaneously pressing the cut, equal-length round rod forward along the sleeve. When the round rod reaches the specified length, the electric cutter continues to move downward. At this time, the drive rod rotates clockwise, meaning that the first baffle continuously contacts the second baffle but cannot act on it. The rotating ring does not rotate at this time. The electric cutter is driven to move up and down reciprocally by an external hydraulic device, thus achieving fully automated operation from feeding to cutting without manual intervention. This significantly improves the automation level of the equipment, eliminates the need for frequent machine control, and enhances production safety. Furthermore, the number of rotations of the drive wheel can be controlled simply by controlling the upward movement distance of the sliding frame, thereby controlling the cutting length. It is simple to use and easy to learn quickly. Attached Figure Description

[0019] First embodiment: as follows Figures 1 to 7 As shown, the present invention provides a technical solution: a fixed-length cutting device for raw materials used in screwdriver manufacturing, comprising a base plate 1, a cutting groove 2 extending through the upper surface of the middle part of the base plate 1, and sleeves 3 symmetrically arranged on both sides of the cutting groove 2, wherein the openings at both ends of the sleeves 3 are arranged radially, and further comprising: Cutting mechanism 4 is fixedly installed on the upper surface of base plate 1; Equal length conveying assembly 5 is fixedly installed on the upper surface of the base plate 1, and the equal length conveying assembly 5 is connected to the cutting mechanism 4. The cutting mechanism 4 includes a slide rod 41, which is symmetrically and fixedly connected to the upper surface of the base plate 1. A stabilizing frame 42 is fixedly installed on the top of the slide rod 41, and a sliding frame 43 is slidably connected to the slide rod 41. An electric cutting machine 44 is fixedly installed in the middle of the sliding frame 43. The electric cutting machine 44 is positioned opposite the cutting groove 2 on the base plate 1, and a hydraulic device is externally connected to the top of the electric cutting machine 44.

[0020] A sliding lower seat 45 is elastically slidably sleeved on the bottom outer surface of the slide rod 41, and an elastic telescopic cylinder 46 is fixedly installed on the upper surface of the sliding lower seat 45, wherein the elastic force of the elastic telescopic cylinder 46 is less than the elastic force between the sliding lower seat 45 and the slide rod 41. Mounting brackets 47 are symmetrically fixedly connected to the upper surface of the middle part of the base plate 1. The mounting brackets 47 are set in pairs, and there are two sets of mounting brackets 47. The inner ends of the mounting brackets 47 are symmetrically fixedly connected to the outer surfaces of the two sleeves 3 that are close to each other. At the same time, a fixing seat 48 is slidably mounted on the mounting bracket 47. The fixing seat 48 consists of two parts, and the two fixing seats 48 are respectively set on both sides of the mounting bracket 47. A stabilizing rod 49 is fixedly connected to the outer end of the mounting bracket 47. The inner end of the stabilizing rod 49 is fixedly connected to the outer surface of the sleeve 3, and the fixing seat 48 is slidably connected to the stabilizing rod 49. A telescopic rod 410 is also fixedly installed on the outer end of the mounting bracket 47. The telescopic rod 410 is sleeved on the stabilizing rod 49. The output end of the telescopic rod 410 is fixedly connected to the outer surface of the fixing seat 48. The mounting bracket 47 also has a reserved interface. The internal cavity of the telescopic rod 410 is connected to the internal cavity of the elastic telescopic cylinder 46 through the reserved interface using a flexible hose.

[0021] A limiting rod 411 is rotatably mounted on the bottom surface of the base plate 1. The limiting rod 411 is a threaded rod, wherein the threads at both ends of the limiting rod 411 are symmetrically arranged, and the bottoms of the two fixing seats 48 on the same sleeve 3 are respectively threaded to the two ends of the limiting rod 411. A synchronizing rod 412 is also fixedly installed on the bottom outer surface of the mounting base 48. The synchronizing rod 412 is U-shaped, and the other end of the synchronizing rod 412 is fixedly connected to the bottom of the mounting base 48 on another set of mounting brackets 47.

[0022] Second embodiment: as follows Figures 1 to 7 As shown, the equal-length conveying assembly 5 includes an upper slide block 51, which is elastically slidably sleeved on the top outer surface of the slide rod 41. A drive rod 52 is rotatably connected to the middle upper surface of the upper slide block 51. The drive rod 52 is configured as a threaded rod, and the top of the drive rod 52 is threadedly connected to the stabilizer 42.

[0023] Rotating rings 53 are rotatably connected to the upper surfaces of both ends of the stabilizer 42, and adapter rods 54 are symmetrically rotatably connected to both ends of the stabilizer 42. The bottom of the adapter rods 54 is rotatably connected to the upper surface of the base plate 1. An upper drive belt 55 is rotatably connected to the outer surface of the rotating ring 53. The end of the upper drive belt 55 away from the rotating ring 53 is rotatably connected to the outer surface of the adapter rod 54. A lower drive belt 56 is rotatably connected to the bottom outer surface of the adapter rod 54.

[0024] The interior of the rotating ring 53 is hollow, and the inner wall of the rotating ring 53 is rotatably connected to the adapter ring 57, which is slidably connected to the drive rod 52. The outer surface of the adapter ring 57 is hinged to a first baffle 58 by a torsion spring, and the inner surface of the rotating ring 53 is fixedly connected to a second baffle 59, wherein both the first baffle 58 and the second baffle 59 are inclined.

[0025] A loading frame 510 is symmetrically fixedly connected to the upper edge of the base plate 1. The loading frame 510 is U-shaped. The upper and lower sides of the loading frame 510 are elastically slidably connected to sliders 511. A drive wheel 512 is rotatably connected to the slider 511. The outer side of the drive wheel 512 is made of rubber. The end of the lower transmission belt 56 away from the adapter rod 54 is rotatably connected to the central axis of the drive wheel 512.

[0026] During operation, the round rod to be cut to the same length is inserted into the two sleeves 3. Then, the electric cutting machine 44 is started and driven by an external hydraulic device to move down along the slide bar 41. Finally, the round rod is cut by the electric cutting machine 44. When the electric cutting machine 44 moves down, it means that the sliding frame 43 moves down along the slide bar 41 and gradually contacts and squeezes the elastic telescopic cylinder 46 on the lower sliding seat 45. Initially, the elastic force provided by the lower sliding seat 45 squeezes the elastic telescopic cylinder 46 first, and then transmits its internal air pressure to the telescopic rod 410 on the mounting frame 47, causing the telescopic rod 410 to start to expand along the stabilizing rod 49, thereby pushing the fixed seats 48 on the mounting frame 47 to move closer to each other. Finally, through the two sets, that is, the four fixed seats 48, the rod is cut. The mutual compression and cooperation of the components compress and fix the two ends of the round rod being cut. As the electric cutting machine 44 moves downward, the compressive force increases until it is completely fixed. At this point, the elastic telescopic cylinder 46 can no longer retract, and the compressive force begins to brake the sliding seat 45 to move downward along the sliding rod 41 until the electric cutting machine 44 completes the cutting of the round rod. After the cutting is completed, the electric cutting machine 44 is driven to move upward, causing the sliding seat 45 to reset as a whole. After the sliding seat 45 resets, as the sliding frame 43 continues to move upward, the elastic telescopic cylinder 46 begins to expand and reset, thereby driving the fixed seat 48 to move towards the outer end of the mounting frame 47 to release the fixation of the round rod. In other words, this equipment automatically compresses and fixes the round rod during cutting, avoiding the need for frequent adjustments required by traditional cutting equipment. The equipment overcomes the drawbacks of fixed fixing and can automatically release the fixing effect after cutting, greatly improving the productivity and speeding up production. Because of its flexible fixing, the equipment automatically adapts to cutting round rods of different diameters, further expanding its applicability and reducing production costs. Simultaneously, the two sleeves 3 can provide small-range limiting to both ends of the round rod during cutting, restricting rod vibration and significantly reducing the problem of low cutting accuracy caused by rod vibration during traditional cutting equipment. This also reduces the possibility of burrs and flash. After cutting, the sliding frame 43 moves upward, causing the fixed seat 48 to reset. As it continues to move upward, it gradually contacts and presses against the upper sliding seat 51, thus... The upper slide block 51 moves upward along the slide rod 41, thereby driving the drive rod 52 to move upward. Since the drive rod 52 is a threaded rod and its top is threadedly connected to the stabilizer 42, the drive rod 52 will rotate as it moves upward with the upper slide block 51. This will cause the adapter ring 57 to rotate counterclockwise and move upward. When the adapter ring 57 rotates counterclockwise, it will drive the rotating ring 53, which is equipped with the second baffle 59, to rotate through the first baffle 58. This will then drive the adapter rod 54 to rotate counterclockwise through the upper transmission belt 55. Finally, it will drive the drive wheel 512 to rotate counterclockwise through the lower transmission belt 56 at the bottom. Thus, the round rod will automatically move forward through the clamping and rolling effect of the two drive wheels 512, while the cut equal-length round rod will be continuously squeezed and pushed forward along the sleeve 3.After the round rod advances to the designated length, the electric cutting machine 44 continues to move downwards. At this time, the drive rod 52 rotates clockwise, meaning that the first baffle 58 continuously contacts the second baffle 59 but cannot act on it. Meanwhile, the rotating ring 53 does not rotate. The electric cutting machine 44 is driven by an external hydraulic device to reciprocate up and down, achieving fully automated operation from loading to cutting without manual intervention. This significantly improves the automation level of the equipment, reduces the need for frequent machine control, and enhances production safety. Furthermore, simply controlling the upward movement distance of the sliding frame 43 controls the number of rotations of the drive wheel 512, thereby controlling the cutting length. It is simple to use and easy to learn quickly.
