Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of hand-operated drill chuck production equipment, and relates to a round steel forging and cutting production line. Background Technology
[0002] Round steel is an important material for the production of drill body components in hand-tightened drill chucks. When forming the drill body, round steel is selected as raw material and forged into appropriate lengths using a cold heading machine. The stable and precise feeding of round steel to the cold heading machine requires a well-designed forging and cutting production line.
[0003] Patent application publication number CN107098155A discloses a small automatic steel pipe feeding device, including a storage platform, a primary feeding device, an adjusting storage box, a secondary feeding box, a conveying device, a tertiary feeding device, and a control system. The primary feeding device is provided on one side of the lower end of the storage platform, and the adjusting storage box is provided on one side of the primary feeding device. The adjusting storage box contains an adjusting device, and the adjusting storage box is connected to the secondary feeding box through the secondary feeding port. The tertiary feeding device is provided with several positioning groove supports, and the tertiary feeding port cooperates with the positioning groove supports. The conveying device is provided with several conveying rollers.
[0004] The aforementioned device can convey round steel materials one by one. However, the round steel materials still need to undergo multiple processing steps during the conveying process to the forging station. The round steel needs to be conveyed sequentially along its length for pre-treatment. Simultaneously, to ensure the continuity of forging production, a spare parts area is often set up on one side of the forging position. After forging, the round steel is directly lifted from the spare parts area and lowered to the forging position for continuous forging. Considering that the spare parts area has an up-and-down moving operating mechanism, setting up a device to drive the axial movement of the round steel would be difficult and costly. Therefore, ensuring a smooth supply of steel from the spare parts area to the forging position is crucial. Ensuring that the round steel can be completely conveyed axially to the spare parts location under the condition of the original part presents significant design challenges. To address these issues, those skilled in the art may consider the following: 1. Setting the support plate at the spare parts location to have a certain inclination along the direction of the round steel, so that the round steel can slide downwards into position after being partially conveyed to the spare parts location, and then be lifted and laterally moved into the forging and cutting position; 2. Setting the support plate at the spare parts location to be a smooth plate, as close as possible to and precisely aligned with the discharge end of the preceding conveying device, so that the round steel with initial velocity can slide into position on the support plate at the spare parts location in a straight state. Summary of the Invention
[0005] To address the aforementioned problems in existing technologies, this invention provides a round steel forging and cutting production line. The technical problem this invention aims to solve is: how to ensure the reliability of round steel feeding while controlling equipment costs.
[0006] The objective of this invention can be achieved through the following technical solutions:
[0007] A round steel forging and cutting production line includes a forging and cutting support and a conveying support. The conveying support is equipped with a conveying device for actively conveying round steel. The forging and cutting support has parallel forging grooves and a spare part plate. The top surface of the spare part plate is inclined from top to bottom toward the side where the forging groove is located. The forging and cutting support between the forging groove and the spare part plate has a vertically arranged baffle plate parallel to the spare part plate. The spare part plate can move up and down along the baffle plate to make the round steel fall from the baffle plate to the forging groove. The characteristic is that the conveying support between the conveying device and the spare part plate is equipped with an upper roller and a lower roller that can clamp the round steel and convey it axially to the spare part plate. The upper roller is vertically opposite to the lower roller. When the spare part plate moves upward and drives the round steel to move up along the baffle plate, the upper roller can move upward.
[0008] The forging slot on the forging support is used to position and orient the round steel bars into the cold heading machine for forging. The spare parts plate is used to hold the round steel bars to be placed in the forging slot to ensure continuous processing. The conveying device on the conveying support is used to drive the round steel bars for oriented transport. The inclined spare parts plate and the baffle plate work together to keep the round steel bars placed on the spare parts plate stable and continuously pressed against the baffle plate. When the spare parts plate moves upward relative to the baffle plate, it can extend beyond the baffle plate, allowing the round steel bars to fall into the forging slot on the other side of the baffle plate under gravity, achieving continuous feeding. By setting upper and lower rollers on the conveying support between the conveying device and the spare parts plate, it is convenient for the round steel bars driven by the conveying device to enter between the upper and lower rollers, where they are clamped. The round steel is held and conveyed to the spare parts plate through at least one active rotation. That is, the upper roller and the lower roller are the last driving source for the round steel to be conveyed to the spare parts plate, without the need to set up an additional device to drive the round steel to feed at the spare parts plate. At the same time, when the conveying device drives the subsequent round steel to enter between the upper roller and the lower roller, it can push out the previous round steel that was stuck on the lower roller due to being disengaged, thus ensuring that the previous round steel is in place. There is no need to set up an additional device to drive the axial movement of the previous round steel on the spare parts plate. At this time, the subsequent round steel reaches the preparatory position and the conveying device stops feeding. After the round steel in the forging groove is processed, the spare parts plate drives the round steel to move upward. At this time, the upper roller moves upward, thus avoiding interference between the rear end of the round steel and the movement of the upper roller, making the round steel feeding on the spare parts plate smoother and more reliable.
[0009] In the aforementioned round steel forging and cutting production line, the conveying support is spaced apart from the forging and cutting support along the setting direction of the spare parts plate, leaving a suspension space. The upper roller and the lower roller are both arranged at the edge of the conveying support near the forging and cutting support. Thus, after the first round steel is pushed out by the subsequent round steel and detaches from it, the rear end of the first round steel will be suspended in the suspension space under the action of gravity, causing the rear end of the first round steel to bend downwards. At this time, due to the reduced top-view length of the rear end, the first round steel will bend further during the acceleration process as it rises with the spare parts plate, thereby greatly reducing the probability of interference with the upper roller and the front end of the subsequent round steel during the rising process. This ensures smooth and reliable round steel feeding while controlling equipment costs.
[0010] In the aforementioned round steel forging and cutting production line, there are at least two upper rollers and two lower rollers. Multiple upper rollers are arranged opposite each other and spaced apart along the length of the spare parts plate, and multiple lower rollers are also arranged opposite each other and spaced apart along the length of the spare parts plate. This arrangement helps maintain the straightness of the round steel as it is conveyed between the upper and lower rollers, preventing excessive warping of the steel ends from affecting the clamping and conveying effect of the upper and lower rollers. It also helps reduce end deviation of the round steel, ensuring that subsequent round steel can smoothly eject the preceding round steel.
[0011] In the aforementioned round steel forging and cutting production line, the conveying support is equipped with a downward-facing drive cylinder one. The upper roller is rotatably connected to the output end of the drive cylinder one, and the lower roller is driven by a motor. The bottom of the spare parts plate is connected to a drive cylinder two mounted on the forging and cutting support. Specifically, the upper roller is controlled to move up and down by the drive cylinder one, while the lower roller is driven to rotate actively by the motor. The upper roller presses the round steel onto the lower roller, thus clamping the round steel. Simultaneously, the spare parts plate is controlled to move up and down by the drive cylinder two, achieving lifting control. Of course, drive cylinder one and drive cylinder two can also be other existing drive components that achieve stroke control.
[0012] In the aforementioned round steel forging and cutting production line, the forging and cutting support is equipped with a first position sensor for detecting the position of the round steel. The first position sensor is positioned near the spare parts plate at the end away from the conveying support and faces the baffle plate. The conveying support is equipped with a second position sensor capable of detecting the position of the round steel between the upper and lower rollers. It can be designed so that when the rear end of the first round steel just leaves the clamp of the upper and lower rollers, its front end is already close to the first position sensor. The subsequent round steel pushes out of the first round steel to achieve its final position. In this way, the first position sensor can detect whether the front end of the first round steel is already in place on the spare parts plate, while the second position sensor detects whether the subsequent round steel has actually entered between the upper and lower rollers. This facilitates the use of an existing controller to stop the upper and lower rollers from continuing to drive the subsequent round steel when a detection signal is generated simultaneously, avoiding excessive extension of the subsequent round steel and interference with the feeding of the first round steel.
[0013] In the aforementioned round steel forging production line, a third position sensor for detecting the position of the round steel is installed on the outer side of the forging groove away from the conveying support. The distance between the third position sensor and the conveying support is greater than the distance between the first position sensor and the conveying support. This facilitates the use of the signal from the third position sensor to control the rise of the upper roller and the spare parts plate via the existing controller after the round steel in the forging groove is processed, ensuring processing continuity and ensuring that the round steel falling into the forging groove is not interfered with by the round steel being forged.
[0014] In the aforementioned round steel forging and cutting production line, the conveying device includes at least two first straightening rollers arranged vertically at intervals and capable of simultaneously clamping and feeding round steel, and at least two second straightening rollers arranged horizontally at intervals and capable of simultaneously clamping and feeding round steel. The second straightening rollers are perpendicular to the first straightening rollers and can jointly clamp the same round steel. In this way, by cooperating with multiple first straightening rollers and multiple second straightening rollers, the radial vertical direction and the front-back direction of the conveyed round steel can be mechanically clamped and straightened, making the direction of the round steel more stable and the processing accuracy higher during subsequent processing, and making the feeding smoother and more reliable.
[0015] In the aforementioned round steel forging and cutting production line, the conveying device further includes at least two third straightening rollers that are spaced apart vertically and arranged obliquely, capable of simultaneously clamping the round steel feed, and at least two fourth straightening rollers that are arranged perpendicular to the three straightening rollers and capable of clamping the same round steel feed. This further mechanically straightens the oblique position of the round steel in the radial direction, achieving calibration in eight radial directions to make the round steel straighter, and making subsequent processing and feeding smoother and more reliable.
[0016] In the aforementioned round steel forging and cutting production line, the conveying support is equipped with a deburring device that can scrape the outer circumference of the round steel. The deburring device is located on the side of the upper and lower rollers away from the spare parts plate. In this way, the existing deburring device can physically eliminate burrs and rust on the outer circumference of the round steel, making the round steel smoother before it is conveyed to the spare parts plate.
[0017] In the aforementioned round steel forging and cutting production line, both the upper and lower rollers have circumferentially arranged arc-shaped grooves that adapt to the shape of the round steel's outer periphery. This increases the contact area between the round steel and the upper and lower rollers, ensuring the stability of the round steel's clamping and conveying.
[0018] In the aforementioned round steel forging and cutting production line, the deburring device is located between the calibration roller and the upper roller. This allows the round steel to be straightened before deburring, which improves the deburring effect of the device.
[0019] In the aforementioned round steel forging production line, the forging groove is equipped with actively rotating conveyor rollers, and the forging support is equipped with a pressing roller that can move downwards relative to the conveyor rollers. In this way, the round steel in the forging groove can be supported on the conveyor rollers, and in conjunction with the pressing rollers, stable directional feeding of the round steel can be achieved.
[0020] In the aforementioned round steel forging and cutting production line, a vertically downward-arranged drive cylinder three is connected to the forging and cutting support. The pressure roller is rotatably connected to the output end of the drive cylinder three, and the conveying roller is driven by a motor. The drive cylinder three enables the pressure roller to move up and down, and the conveying roller is driven by the motor to rotate actively, thereby controlling the feeding of the round steel.
[0021] Compared with the prior art, the advantages of the present invention are as follows:
[0022] This round steel forging and cutting production line can achieve smooth round steel transport without setting up a round steel conveying device at the spare parts location. The overall design cost of the production line is low, which is conducive to large-scale application and has smooth processing and high efficiency. Attached Figure Description

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.
[0034] like Figure 1-4 , Figure 6As shown, this round steel forging production line includes a forging support 1 and a conveying support 2. The conveying support 2 is equipped with a conveying device 3 that can actively convey round steel. The forging support 1 has forging grooves 11 arranged in parallel left and right and a spare plate 4. The top surface of the spare plate 4 is inclined from top to bottom toward the side where the forging grooves 11 are located. The forging support 1 between the position of the forging grooves 11 and the spare plate 4 has a vertically arranged baffle plate 12. The baffle plate 12 is arranged along the length direction of the spare plate 4. The spare plate 4 can move along the baffle plate 12. 2. The up-and-down movement causes the round steel to fall from the baffle plate 12 to the forging groove 11. The conveying support 2 between the conveying device 3 and the spare parts plate 4 is equipped with an upper roller 21 and a lower roller 22 that can clamp the round steel and convey it axially to the spare parts plate 4. The upper roller 21 is vertically opposite to the lower roller 22. The lower roller 22 is driven by a motor. When the spare parts plate 4 is driven upward by the bottom drive cylinder 2 and moves the round steel upward along the baffle plate 12, the upper roller 21 is driven upward by the upper drive cylinder 24 of the conveying device 3. The forging groove 11 on the forging support 1 is used to position and orient the round steel into the cold heading machine for forging. The spare plate 4 is used to place the round steel to be entered into the forging groove 11 to ensure the continuity of processing. The conveying device 3 on the conveying support 2 is used to drive the round steel for orienting. The inclined spare plate 4 and the baffle plate 12 cooperate to keep the round steel placed on the spare plate 4 stable and continuously abutting against the baffle plate 12. When the spare plate 4 moves upward relative to the baffle plate 12, the spare plate 4 can exceed the baffle plate 12, allowing the round steel to fall into the forging groove 11 on the other side of the baffle plate 12 under the action of gravity, thus achieving continuous feeding. By setting an upper roller 21 and a lower roller 22 on the conveying support 2 between the conveying device 3 and the spare plate 4, the lower roller 22 can be driven by a motor to rotate actively. This facilitates the entry of the round steel driven by the conveying device 3 into the upper roller 21 and the lower roller 22. Between them, the round steel is clamped and conveyed to the spare parts plate 4 by at least one active rotating wheel. That is, the upper roller 21 and the lower roller 22 are the last driving source for the round steel to the spare parts plate 4, and there is no need to set an additional device to drive the round steel to feed at the spare parts plate 4. At the same time, when the conveying device 3 drives the subsequent round steel into the space between the upper roller 21 and the lower roller 22, the previous round steel that was stuck on the lower roller 22 due to being disengaged can be pushed out, thus ensuring that the previous round steel is in place. There is no need to set an additional device to drive the axial movement of the previous round steel on the spare parts plate 4. At this time, the subsequent round steel reaches the preparatory position and the conveying device 3 stops feeding. After the round steel in the forging groove 11 is processed, the spare parts plate 4 drives the round steel to move upward. At this time, the upper roller 21 is driven upward by the cylinder, thus avoiding the interference between the rear end of the round steel and the upper roller 21, making the round steel feeding on the spare parts plate 4 smoother and more reliable.Preferably, there are two upper rollers 21 and two lower rollers 22. The two upper rollers 21 are arranged opposite each other and spaced apart along the length of the spare parts plate 4, and the two lower rollers 22 are arranged opposite each other and spaced apart along the length of the spare parts plate 4. The conveying bracket 2 is spaced apart from the forging and cutting bracket 1 along the setting direction of the spare parts plate 4, leaving a suspension space 5. The upper rollers 21 and lower rollers 22 are arranged at the edge of the conveying bracket 2 near the forging and cutting bracket 1. In this way, after the first round steel is pushed out by the subsequent round steel and separates from the subsequent round steel, the rear end of the first round steel will be suspended in the suspension space 5 under the action of gravity, causing the rear end of the first round steel to bend downward. At this time, because the top-view length of the rear end of the first round steel is reduced, it will bend further during the acceleration process of rising with the spare parts plate 4, thereby greatly reducing the probability of interference with the upper rollers 21 and the front end of the subsequent round steel during the rising process. Under the condition of controlling equipment costs, it ensures smooth and reliable feeding of round steel. Since the round steel is only suspended for a short time, it will not affect the straightness of the round steel. Both the upper roller 21 and the lower roller 22 have circumferentially arranged arc-shaped grooves 7 that adapt to the shape of the round steel. This increases the contact area between the round steel and the upper roller 21 and the lower roller 22, ensuring the stability of the round steel's clamping and conveying. The forging groove 11 has two actively rotating conveying rollers 15 spaced apart along its direction. The forging support 1 has two clamping rollers 16 that can move up and down relative to the conveying rollers 15. Specifically, the clamping rollers 16 are directly driven by a drive cylinder 3 18 connected to the forging support 1. In this way, the round steel in the forging groove 11 can be supported on the conveying rollers 15, and in conjunction with the clamping rollers 16, stable directional conveying of the round steel can be achieved.
[0035] like Figure 1-6As shown, the forging and cutting support 1 is equipped with a first position sensor 13 for detecting the position of the round steel. The first position sensor 13 is arranged near the spare parts plate 4 at the end away from the conveying support 2 and faces the baffle plate 12. The conveying support 2 is equipped with a second position sensor 23 that can detect the position of the round steel between the upper roller 21 and the lower roller 22. It can be designed so that when the rear end of the first round steel just leaves the clamp of the upper roller 21 and the lower roller 22, its front end is already close to the first position sensor 13. The subsequent round steel pushes out of the first round steel to achieve the final position. In this way, the first position sensor 13 can be used to detect whether the front end of the first round steel has been positioned on the spare parts plate 4, and the second position sensor 23 can detect whether the subsequent round steel has actually entered between the upper roller 21 and the lower roller 22. This is beneficial because when a detection signal is generated at the same time, the existing controller can stop the upper roller 21 and the lower roller 22 from continuing to drive the subsequent round steel, avoiding the subsequent round steel from extending too far and interfering with the feeding of the first round steel. A third position sensor 14 for detecting the position of the round steel bar is provided on the outer side of the end of the forging groove 11 away from the conveying support 2. The distance between the third position sensor 14 and the conveying support 2 is greater than the distance between the first position sensor 13 and the conveying support 2. This facilitates the upward movement of the upper roller 21 and the spare parts plate 4 via the signal from the third position sensor 14 after the round steel bar in the forging groove 11 has been processed, ensuring the continuity of processing. At the same time, it fully ensures that the round steel bar falling into the forging groove 11 will not be interfered with by the round steel bar being forged.
[0036] like Figure 1 , Figure 3As shown, the conveying device 3 includes five first straightening rollers 31 arranged vertically at intervals and capable of simultaneously clamping and feeding round steel bars, and five second straightening rollers 32 arranged horizontally at intervals and capable of simultaneously clamping and feeding round steel bars. The second straightening rollers 32 are perpendicular to the first straightening rollers 31 and can jointly clamp the same round steel bar. The first straightening rollers 31 are driven by a motor. In this way, the multiple first straightening rollers 31 and multiple second straightening rollers 32 work together to mechanically clamp and straighten the conveyed round steel bars in the radial vertical direction and the front-back direction, making the round steel bars more stable in direction and achieving higher processing accuracy in subsequent processing, and making feeding smoother and more reliable. The conveying device 3 also includes five third straightening rollers 33 arranged vertically at intervals and obliquely and capable of simultaneously clamping and feeding round steel bars, and five fourth straightening rollers 34 arranged perpendicular to the three straightening rollers and capable of clamping and feeding the same round steel bar. This further mechanically straightens the radial oblique position of the round steel, achieving calibration in eight radial directions to make the round steel straighter, thus making subsequent processing and feeding smoother and more reliable. The conveyor support 2 is equipped with a deburring device 6 that scrapes the outer circumference of the round steel. The deburring device 6 is existing equipment, located on the side of the upper roller 21 and lower roller 22 away from the spare parts plate 4. This existing deburring device 6 can physically eliminate burrs and rust on the outer circumference of the round steel, making the round steel smoother before being conveyed to the spare parts plate 4. The deburring device 6 is located between the calibration roller and the upper roller 21. This allows the round steel to be straightened before deburring, improving the deburring effect of the deburring device 6.
