Description

Technical Field

[0001] This utility model relates to bar production equipment, and more specifically to a bar hot forging feeding device. Background Technology

[0002] Currently, when hot forging equipment is used to forge red-hot metal billets into die forgings, a feeding device is needed to transport the bar stock to the forging machine. This feeding device includes interconnected conveyor slides and guide pipes. The bar stock enters the upper surface of the forging machine frame through the conveyor slides and guide pipes in sequence, so that the clamping mechanism in the forging machine can clamp the bar stock and transport it to the workstation for the stamping and forging process. However, with the above-mentioned feeding device, the bar stock enters the forging machine vertically, which cannot meet the requirement that some bars need to be stamped and forged in a horizontal position.

[0003] Based on this, some people use two interconnected conveyor slides to allow the bar stock to enter the forging equipment in a horizontal state. However, when the bar stock is in the rear conveyor slide, it is not within the clamping range of the clamping mechanism. Therefore, a cylinder device needs to be installed in the rear conveyor slide to push the bar stock out of the rear conveyor slide so that the bar stock is within the clamping range, which is convenient for subsequent operations. However, with the above-mentioned feeding device, the bar stock is prone to deviation, which is not conducive to subsequent operations.

[0004] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0005] The purpose of this invention is to provide a bar hot forging feeding device that enables the bar to enter the corresponding area in a horizontal position, with accurate positioning and convenient subsequent operation.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A bar hot forging feeding device is located at the front end of a forging equipment. It includes a frame and a conveying slide mounted on the frame. The conveying slide is arranged inclined from top to bottom along the conveying direction, and the rear ends of the two opposite side walls of the conveying slide extend rearward to form conveying limiting parts. A limiting frame surrounding the two conveying limiting parts is provided around the rear end of the conveying slide. The limiting frame and the two conveying limiting parts together form a limiting area. A pushing device is installed on the lower side of the limiting area. A feeding platform is provided on the transmission component of the pushing device. The feeding platform is raised and lowered under the drive of the transmission component to contact or separate from the two conveying limiting parts.

[0008] The pushing device includes a pushing cylinder, the transmission component of the pushing device is the piston rod of the pushing device, and the cylinder body of the pushing cylinder is located below the piston rod of the pushing cylinder; or, the pushing device includes a pushing electric rod, the transmission component of the pushing electric rod is the telescopic rod of the pushing electric rod.

[0009] The conveying chute includes an inclined plate mounted on the frame and two guide plates mounted on the inclined plate. The inclined plate is arranged inclined from top to bottom along the conveying direction, and the two guide plates are arranged opposite to each other.

[0010] The two guide plates and the two conveying limiting parts are respectively matched one-to-one, and the rear ends of the two guide plates are integrally connected to the conveying limiting parts. The two conveying limiting parts are arranged along the front-back direction.

[0011] The front ends of the two guide plates are respectively provided with plate holes, and the two plate holes correspond to each other. A material blocking device is installed on the outer side of the conveying slide. A material blocking rod is driven to the transmission component of the material blocking device, and the two plate holes are located on the moving path of the material blocking rod.

[0012] A sensor is installed on the outer side of the conveyor chute near the material blocking device. The sensor probe corresponds to the inside of the conveyor chute, and the sensor is located behind the material blocking device.

[0013] The material blocking device includes a material blocking cylinder, and the transmission component is the piston of the material blocking cylinder; or the material blocking device includes a material blocking electric rod, and the transmission component is the telescopic rod of the material blocking electric rod.

[0014] The sensor is a proximity switch.

[0015] The limiting frame is U-shaped, and its two ends are respectively installed on the frame.

[0016] The feeding platform is located within the clamping range of the clamping mechanism in the forging equipment.

[0017] By adopting the above structure, this utility model has the following beneficial effects:

[0018] 1. This utility model uses a conveyor slide to transport bar stock, and a limiting area to limit the bar stock. Combined with the cooperation of the pushing device, as the bar stock slides backward, the transmission component of the pushing device pushes the feeding platform upward to contact the two conveying limiting parts. This ensures that when the bar stock slides to the two conveying limiting parts, it is in a horizontal position on the feeding platform and cannot move further backward due to the action of the limiting frame. At the same time, due to the combined action of the two conveying limiting parts, the bar stock cannot tilt to the sides of the conveyor slide, thus providing double limiting for the bar stock, i.e., positioning the bar stock. Then, the feeding platform descends under the action of the pushing device, driving the bar stock downward to enter the front end of the forging equipment, so that the bar stock is within the clamping range of the clamping mechanism in the forging equipment, facilitating subsequent operations.

[0019] 2. This utility model adopts a material blocking device and a two-plate hole setting. When the material blocking rod on the material blocking device extends, the material blocking rod passes through the two plate holes in sequence to block the front end of the conveying slide. Combined with the sensor, it ensures that only one bar passes through the conveying slide at a time, realizing automated operation. Attached Figure Description

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] A bar hot forging feeding device, such as Figure 1-3As shown, it cooperates with the clamping mechanism 1a in the forging equipment. The forging equipment is a conventional forging equipment used for forging bars such as nuts and bolts. The clamping mechanism on it is also a conventional clamping mechanism, such as a cylinder-driven clamping robot. In this embodiment, the forging equipment can be the forging equipment described in the application with application number "202321454161.9" and title "A clamping mechanism and a forging equipment provided with a clamping mechanism".

[0030] For ease of description, the reference direction of this utility model is the state under normal use, and the direction of conveying the bar stock is from front to back, while the horizontal direction perpendicular to the front and back is the left and right direction.

[0031] The aforementioned hot forging bar feeding device includes a frame 1 and a conveyor chute 2. The frame 1 is mounted on the front end of the aforementioned forging equipment. The conveyor chute 2 is installed on the frame 1 and is arranged inclined backward from top to bottom. The front end of the conveyor chute 2 connects to the outlet of the heating platform of the hot forging equipment, so that the hot-forged bar can be smoothly transferred into the conveyor chute 2. The hot forging equipment is a conventional hot forging equipment, and the heating platform is part of the hot forging equipment, which can be an induction furnace. The rear ends of the two opposite side walls of the conveyor chute 2 extend backward to form conveying limiting parts 21, and the two conveying limiting parts 21 are arranged face to face. A limiting frame 22 is provided at the rear end of the conveyor slide 2. The limiting frame 22 is U-shaped, that is, the two ends of the limiting frame 22 are respectively fixedly installed on the frame 1 at the rear end of the conveyor slide 2, so that the limiting frame 22 surrounds both conveying limiting parts 21. The limiting frame 22 and the two conveying limiting parts 21 together form a limiting area. A pushing device is installed directly below the limiting area. That is, the pushing device is installed on the forging frame 2a of the forging equipment. The transmission component of the pushing device is connected to the feeding platform 3. The feeding platform 3 rises or falls under the drive of the transmission component to contact or separate from the two conveying limiting parts 21.

[0032] Furthermore, the aforementioned pushing device includes a pushing cylinder 4, which is driven by an air source. The pushing cylinder 4 is arranged vertically, and its cylinder body is fixedly mounted on the forging frame 2a of the aforementioned forging equipment. The transmission component of the pushing cylinder 4 is the piston rod of the pushing cylinder, which is located on the upper side of the cylinder body of the pushing cylinder 4. The piston rod is connected to the feeding platform 3, and the two are connected together by conventional methods such as bolts or plugs. Ideally, the feeding platform 3 and the piston rod are arranged perpendicular to each other to ensure that the upper side of the feeding platform 3 does not tilt.

[0033] In this embodiment, the aforementioned pushing device can also be an electric push rod device, which includes a pushing electric rod. The pushing electric rod is a conventional electric rod that is driven by a power source. The transmission component of the pushing device is the telescopic rod of the pushing electric rod. In addition, the pushing device can also be a commercially available pushing device, such as a hydraulic cylinder device or a lead screw device.

[0034] Furthermore, the aforementioned conveying chute 2 includes an inclined plate 23 and two oppositely arranged guide plates 24. The inclined plate 23 is arranged inclined from top to bottom and backward and is fixedly installed on the frame 1. The two guide plates 24 are respectively located on both sides of the inclined plate 23, and the two guide plates 24 and the two aforementioned conveying limiting parts 21 are respectively matched one-to-one. The rear ends of the two guide plates 24 are integrally connected to the corresponding conveying limiting parts 21. The two conveying limiting parts 21 are arranged in the front-back direction, and there is a hollow part between the two conveying limiting parts 21 so that the bar stock can enter the feeding platform 3 from the hollow part.

[0035] Furthermore, the front ends of the two guide plates 24 are respectively provided with plate holes 241, and the two plate holes 241 correspond to each other. A material blocking device is installed on the outside of the conveying slide 2. In this embodiment, the material blocking device includes a material blocking cylinder 5. The material blocking cylinder 5 is arranged in the left and right direction, and the cylinder body of the material blocking cylinder 5 is fixedly installed on the outside of the conveying slide 2 by a bracket 11. The bracket 11 is fixedly installed on the inclined plate 23 and located on the outside of the conveying slide 2. The piston of the material blocking cylinder 5 is connected to a material blocking rod 51. The two are connected together by a conventional connection method, such as bolt fixing or plug fitting. The material blocking rod 51 corresponds to the two plate holes 241 respectively, and the two plate holes 241 are both located within the extension range of the material blocking rod 51. In this way, when the baffle rod 51 extends under the action of the piston of the baffle cylinder 5, the baffle rod 51 can pass through the two plate holes 241 in sequence to block the conveying slide 2 and prevent multiple bars from entering the conveying slide 2 at the same time; after the baffle rod 51 retracts under the action of the piston of the baffle cylinder 5, the free end of the baffle rod 51 is located outside the conveying slide 2 to avoid blocking the bars from sliding into the conveying slide 2.

[0036] It should be noted that in this embodiment, the aforementioned material blocking device can also be an electric push rod device or a hydraulic cylinder device, or an existing conventional device that can drive the material blocking rod 51 to move left and right, and is not limited to the cylinder device described above.

[0037] Furthermore, a sensor 6 is installed on the outer side of the aforementioned conveyor chute 2 near the material stop device. The sensor 6 is used to detect whether there is bar material on the conveyor chute 2. The sensor 6 is located behind the aforementioned material stop device. In this embodiment, the sensor 6 is installed on one of the guide plates 24, and the probe of the sensor 6 corresponds to the bottom of the conveyor chute 2. The sensor 6 is a conventional sensor, and in this embodiment, the sensor 6 is a conventional proximity switch. In addition, the aforementioned sensor 6 can also be mounted on the frame 1 or on the inclined plate 24.

[0038] In detail, the installation structure of the sensor 6 is as follows: one of the guide plates 24 extends upward to form an installation area 242. The installation area 242 has an installation hole 243. The sensor 6 is fixedly installed in the installation hole 243. The sensor 6 can be fixed to the installation area 242 by fastening or plugging. Preferably, the installation hole 243 is a strip hole, and the installation hole 243 is arranged in the front and back direction to facilitate subsequent adjustment.

[0039] Furthermore, the aforementioned feeding platform 3 has a plate-like structure and is arranged horizontally. The feeding platform 3 is located within the clamping range of the clamping mechanism 1a in the aforementioned forging equipment, and the aforementioned pushing cylinder 4 is located below the clamping mechanism 1a. Thus, when the piston rod of the pushing cylinder 4 extends, the feeding platform 3 contacts the two conveying limiting parts 21 to form the bottom of the two conveying limiting parts 21, which facilitates the carrying of the bar stock. When the piston rod of the pushing cylinder 4 retracts, the feeding platform 3 separates from the two conveying limiting parts 21, and the feeding platform 3 descends into the clamping range of the clamping mechanism 1a in the aforementioned forging equipment, which facilitates the subsequent forging processing of the forging equipment.

[0040] The operation of the bar hot forging feeding device of this utility model is as follows: First, the piston rod of the cylinder 4 is pushed to extend so that the feeding platform 3 abuts against the two conveying limit parts 21. Then, when the sensor 6 detects that a bar is sliding through the conveying slide 2, the piston of the blocking cylinder 5 is activated so that the blocking rod 51 separates the conveying slide 2 to prevent other bars from sliding down. After the bar slides down onto the feeding platform 3, the piston rod of the cylinder 4 is pushed to retract, causing the feeding platform 3 to move down, so that the bar on the feeding platform 3 enters the clamping range of the clamping mechanism 1a. The clamping mechanism 1a starts to operate, clamping the bar and moving it to the corresponding position of the forging equipment. Then, the piston rod of the cylinder 4 is pushed to extend again so that the feeding platform 3 abuts against the two conveying limit parts 21. Then, the piston of the blocking cylinder 5 retracts so that the blocking rod 51 leaves the conveying slide 2. After the next bar enters the conveying slide 2, the above steps are repeated to realize the conveying of the bar.

[0041] Furthermore, the aforementioned conventional forging equipment is equipped with a controller, which is a commercially available PLC controller, such as an Omron PLC or a Mitsubishi PLC. The control terminals of the push cylinder 4 and the stop cylinder 5 are electrically connected to the signal output terminal of the control system, and the signal output terminal of the sensor 6 is electrically connected to the signal input terminal of the control system.

[0042] It should be noted that the time interval between the moment the bar stock is detected by the sensor and the moment it is placed on the feeding platform 3 is manually set in the controller. This time interval is the time value obtained by manual experimentation of the bar stock sliding from the conveyor slide to the feeding platform. In addition, existing conventional methods can also be used to detect whether the bar stock is on the feeding platform 3. For example, a proximity switch is installed on the forging frame, and the proximity switch is oriented between the two conveying limit parts 21.

[0043] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
