Description

Technical Field

[0001] This utility model relates to a heating and loading device for rod-shaped materials, belonging to the technical field of loading and unloading equipment. Background Technology

[0002] Before forging, bar-shaped materials need to be heated in a medium-frequency induction furnace and then transferred to the forging press by a handling robot. During the heating process, the automation and orderliness of the loading and unloading devices directly affect heating efficiency and processing quality. Existing bar-shaped material heating and loading / unloading devices mostly use simple pushing mechanisms and feeders, but they have the following shortcomings: during unloading, the heated bar-shaped materials are prone to accumulation and jamming, making orderly unloading impossible, and it is difficult to accurately detect the unloading situation to control the loading rhythm, resulting in a mismatch between the loading and unloading rhythms and reduced production efficiency; furthermore, they are inconvenient for handling robots to transfer. Utility Model Content

[0003] This invention provides a heating and feeding device for rod-shaped materials, which solves the problems mentioned in the background art.

The pushing and feeding chute is equipped with a pushing plate, which is connected to a pushing mechanism. A stepped feeder is provided on one side of the pushing and feeding chute. An inclined discharge plate is provided below the rear outlet of the medium-frequency heating furnace. Two parallel discharge baffles are installed on the top of the discharge plate. The front end of the discharge baffles is provided with an outward V-shaped bend. A limit baffle is fixed on the discharge plate corresponding to the lower end of the middle line of the two discharge baffles. A laser sensor is provided on the discharge plate between the limit baffle and the discharge baffle. The laser sensor is connected to a controller. The controller is connected to the stepped feeder and the pushing mechanism.

[0005] As a preferred embodiment, the pushing mechanism includes a pushing cylinder fixed to the front end of the pushing and feeding chute, and the pushing cylinder is fixedly connected to the pushing plate. The pushing cylinder serves as a power source, providing stable and controllable power output, thus ensuring power supply for material feeding.

[0006] As a preferred embodiment, the side wall of the feeding chute away from the stepped feeder is higher than the other side wall. A guide rail is fixed to the outer side of the side wall of the feeding chute away from the stepped feeder. The guide rail is connected to a guide slider, and the guide slider is connected to a connecting plate. The connecting plate is fixed to the feeding plate.

[0007] As a preferred embodiment, the top inner side of the stepped feeder is provided with a guide ramp to guide material into the feeding chute. A baffle plate is installed above the guide ramp, and a lifting cylinder is fixed to the top of the baffle plate. The baffle plate and lifting cylinder allow a spare bar to be prepared at the top while the material is being pushed, reducing subsequent feeding time and improving efficiency.

[0008] As a preferred embodiment, the lifting cylinder is fixedly connected to a fixed plate, and L-shaped fixed support plates are fixed at both ends of the fixed plate. The fixed support plates are fixed on the top outer side of the stepped feeder, which facilitates the installation of the fixed plate. The baffle plate is fixed with guide rods symmetrical about the lifting cylinder, and guide sleeves are provided on the guide rods. The guide sleeves are fixed on the fixed plate, making the lifting of the baffle plate more stable.

[0009] As a preferred option, the front end of the medium-frequency heating furnace is equipped with a V-shaped feed chute connecting its inlet and the push-feed chute.

[0010] As a preferred embodiment, both discharge baffles are equipped with adjusting plates on their lower outer sides. Each adjusting plate has a strip-shaped adjusting hole (I) with its center line parallel to the discharge plate. The outer wall of the discharge baffle has adjusting locking bolts that extend into the strip-shaped adjusting holes (I). An adjusting flange is fixed to the bottom of the adjusting plate. Both the upper and lower ends of the adjusting flange have strip-shaped adjusting holes (II) with their center lines perpendicular to the center line of the strip-shaped adjusting hole (I). An adjusting fastening bolt that extends into the strip-shaped adjusting hole (II) is fixed to the discharge plate. The discharge baffles can be adjusted in both left-right and front-back directions via the adjusting plates, adjusting flanges, and the strip-shaped adjusting holes (I and II), allowing the device to accommodate rod-shaped materials of different diameters and expanding its applicability.

[0011] As a preferred embodiment, a support plate is fixed to the bottom of the feeding plate, and an adjusting sleeve is fitted at both ends of the support plate. The adjusting sleeve is equipped with a fixing bolt, and the laser sensors on both sides are fixed on the two adjusting sleeves respectively, so as to facilitate the adjustment of the distance between the laser sensors on both sides.

[0012] As a preferred embodiment, a support frame is fixed to the bottom of the feeding plate, and height adjustment plates are provided on the four outer corners of the support frame. Each height adjustment plate has a vertical height adjustment slot, and a fixing adjustment bolt extending into the height adjustment slot is provided on the lower outer wall of the support frame. This facilitates adjustment of the feeding plate height.

[0013] This utility model has the following beneficial effects:

[0014] By installing a laser sensor on the feeding plate, the passage of rod-shaped materials during the feeding process can be detected in real time, and the signal is transmitted to the controller. The controller then controls the operating rhythm of the stepped feeder and the pushing mechanism, avoiding material accumulation due to excessive feeding or idling of the equipment due to excessive feeding, thus effectively improving production efficiency. The outward V-bend at the front end of the feeding baffle facilitates the smooth entry of the heated rod-shaped materials between the two feeding baffles. The two feeding baffles can guide the materials, and the limiting baffle can block the bottom of the materials, making it convenient for the laser sensor to detect them and for the handling robot to transfer them.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example 1, as Figures 1 to 5As shown, this utility model is a heating and loading device for rod-shaped materials, including a medium-frequency heating furnace 1. A V-shaped feeding chute 4 is connected to the front inlet of the medium-frequency heating furnace 1. The feeding chute 4 is equipped with a pushing plate 5, which is connected to a pushing mechanism. A stepped feeder 2 is located on one side of the feeding chute 4. An inclined discharge plate 14 is located below the rear outlet of the medium-frequency heating furnace 1. Two parallel discharge baffles 13 are installed on the top of the discharge plate 14. The front end of the discharge baffles 13 has an outward V-shaped bend. A limit baffle 18 is fixed on the discharge plate 14 corresponding to the lower middle line of the two discharge baffles 13. A laser sensor 17 is installed on the discharge plate 14 between the limit baffle 18 and the discharge baffle 13. The laser sensor 17 is connected to a controller, which is connected to the stepped feeder 2 and the pushing mechanism. The controller is also connected to a handling robot responsible for transporting the heated rod-shaped materials onto a forging press.

[0023] After the equipment is started, the stepped feeder 2 conveys the rod-shaped material to be heated upwards. When the material reaches the top, it rolls into the pusher loading trough 4. The controller controls the pusher mechanism to start, and the pusher mechanism drives the pusher plate 5 to move, pushing the material in the pusher loading trough 4 backwards and pushing the material in front into the medium frequency heating furnace 1 for heating. After heating, the material is discharged from the rear outlet of the medium frequency heating furnace 1, enters the space between the two discharge baffles 13 through the outward V-bend at the front end of the discharge baffle 13, slides down the inclined discharge plate 14, and stops when it reaches the limit baffle 18. When the material passes through the detection area of ​​the laser sensor 17, the laser sensor 17 sends a signal to the controller. After receiving the signal, the controller controls the multi-degree-of-freedom handling robot to come over, clamp the rod-shaped material and transport it to the forging press. Then the stepped feeder 2 puts the next material into the pusher loading trough 4, and the pusher cylinder 3 starts pushing the material again, realizing automated loading and unloading.

[0024] In Example 2, based on Example 1, the pushing mechanism includes a pushing cylinder 3 fixed to the front end of the pushing feed trough 4, and the pushing cylinder 3 is fixedly connected to the pushing plate 5.

[0025] The side wall of the feeding chute 4 away from the stepped feeder 2 is higher than the other side wall. A guide rail 23 is fixed to the outer side of the side wall of the feeding chute 4 away from the stepped feeder 2. The guide rail 23 is connected to a guide slider, and the guide slider is connected to a connecting plate 6. The connecting plate 6 is fixed to the pushing plate 5. When pushing material, the pushing cylinder 3 extends, bringing the pushing plate 5 closer to the material and pushing it to the right. The pushing plate 5 is guided by the guide rail 23 and the guide slider to prevent deflection.

[0026] The top inner side of the stepped feeder 2 is provided with a guide ramp for guiding the material to the feeding trough 4. A baffle plate 10 is provided above the guide ramp, and a lifting cylinder 8 is fixed on the top of the baffle plate 10.

[0027] The lifting cylinder 8 is fixedly connected to a fixed plate 7. L-shaped fixed support plates 11 are fixed to both ends of the fixed plate 7. The fixed support plates 11 are fixed to the top outer side of the stepped feeder 2. A guide rod 9, symmetrical about the lifting cylinder 8, is fixed on the baffle plate 10. A guide sleeve is provided on the guide rod 9 and fixed to the fixed plate 7. During feeding, the lifting cylinder 8 retracts, releasing the blocked rod-shaped material. The material rolls down the guide slope into the pushing feed chute 4. Then, the lifting cylinder 8 extends, and the pushing cylinder 3 pushes the material. The stepped feeder 2 continues feeding. The next rod-shaped material falling from the top is blocked by the baffle plate 10, waiting for the next feeding.

[0028] The front end of the medium frequency heating furnace 1 is provided with a V-shaped feed chute 12 that connects its inlet and the push feeding chute 4.

[0029] Both discharge baffles 13 have adjusting plates 15 on their lower outer sides. Each adjusting plate 15 has a strip-shaped adjusting hole (first type) with its center line parallel to the discharge plate 14. The outer wall of each discharge baffle 13 has adjusting locking bolts that extend into the first strip-shaped adjusting hole. An adjusting flange 16 is fixed to the bottom of the adjusting plate 15. Both the upper and lower ends of the adjusting flange 16 have second strip-shaped adjusting holes (second type) with their center lines perpendicular to the center line of the first strip-shaped adjusting hole. The discharge plate 14 has adjusting fastening bolts that extend into the second strip-shaped adjusting hole. Before operation, the distance between the two discharge baffles 13 can be adjusted by loosening the adjusting fastening bolts according to the width of the rod-shaped material. The left and right positions of the discharge baffles 13 can also be adjusted by loosening the adjusting locking bolts.

[0030] A support plate 20 is fixed to the bottom of the feeding plate 14. Adjustment sleeves 19 are fitted on both ends of the support plate 20. Fixing bolts are provided on the adjustment sleeves 19. The laser sensors 17 on both sides are fixed on the two adjustment sleeves 19 respectively.

[0031] A support frame 21 is fixed to the bottom of the feeding plate 14. A height adjustment plate 22 is provided on the outer side of each of the four corners of the support frame 21. The height adjustment plate 22 is provided with a vertical height adjustment strip hole.
