Description

Technical Field

[0001] The utility model relates to the technical field of forging processing, in particular to a material receiving and feeding device for producing crawler iron tooth workpieces. Background Art

[0002] In the production of crawler gear parts, the material handling device, a key piece of equipment connecting all processing steps, directly impacts the overall production line's operational status and product quality. While traditional material handling devices can accomplish basic material handling tasks, they often encounter issues with workpiece positional deviation and inconsistent shapes when handling crawler gear parts with complex shapes and irregular structures. This is particularly noticeable after the workpieces are dropped onto the material handling conveyor belt after undergoing the forging process.

[0003] After forging, track teeth must be quenched at a certain residual temperature (usually greater than 800°C) to ensure excellent physical properties and mechanical strength. However, due to heat loss and irregular shapes during transportation, workpieces often become skewed or misaligned. This not only increases the difficulty of subsequent temperature measurement, but can also affect the quenching effect due to unstable workpiece conditions, thereby reducing overall product quality. Existing methods often rely on manual intervention or simple mechanical adjustments, but these methods are not only inefficient but also difficult to guarantee the accuracy of each adjustment, failing to meet the needs of modern, automated production lines.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 、 Figure 2 、 Figure 3 As shown, a feeding and receiving device for the production of crawler iron tooth workpieces includes a receiving device 5, a feeding device 1, a blanking device 2, a controller, and a cylinder device 3, wherein the cylinder device 3 is symmetrically arranged on both sides of the front end of the feeding device 1. Each side of the cylinder device 3 includes a cylinder body 31 and a push rod 32 connected to the cylinder body 31. The push rod 32 is in an extended state by default, and retracts downward once every 5 to 7 seconds and then extends upward. In this embodiment, the extension frequency of the push rod 32 is set to drop and retract once every 6 seconds to allow the workpiece to pass through, ensuring that the time each workpiece 4 spends on the chain remains consistent, the rate at which the workpiece 4 is pushed will not be too fast, and the rhythm consistency of the workpiece 4 production process is ensured. The push rod 32 is used to correct the position of the workpiece 4 during the conveying process. The extended height of the push rod 32 is higher than the height of the feeding device 1. The extended push rod 32 supports the workpiece 4 and makes it stay until the two ends are aligned, which helps to correct the position deviation and incorrect posture of the workpiece 4 and ensure the accuracy and stability of the workpiece 4 in the subsequent processing process. The application of the cylinder device 3 improves the accuracy and efficiency of positioning the workpiece 4 and reduces the processing error and scrap rate caused by the incorrect position of the workpiece 4.

[0024] In practice, the material receiving device 5 includes a connecting plate 52 and two L-shaped plates 51. The two L-shaped plates 51 are mounted on the outside of the chain mounting plate via pins. The two L-shaped plates 51 are equally divided into a front section and a rear section by their respective pin holes. The connecting plate 52 is positioned below the chain mounting plate and fixedly connected to the ends of the rear sections of the L-shaped plates 51. Under the weight of the connecting plate 52 and the rear sections of the L-shaped plates 51, the front sections of the L-shaped plates 51 tilt upward around the pins and partially protrude above the upper surface of the conveyor chain 11. The buffering function of the material receiving device 5 ensures the quality of the workpiece 4.

[0025] In practice, the feeder 1 comprises two parallel, synchronously running conveyor chains 11 and a chain mounting plate. The conveyor chains 11 are driven by independent motors through a sprocket mechanism, ensuring stable and reliable chain operation. The chain mounting plate, located outside the chains, supports and secures them and, together with the conveyor chains 11, provides a platform for placing the workpiece 4. The cylinder devices 3 on either side of the feeder 1 are aligned horizontally. The design of the feeder 1 ensures smooth and continuous delivery of the workpiece 4 to the designated location.

[0026] A transverse limiting rod 12 is provided above the middle section of the feeding device 1 , and the limiting rod 12 can intercept the inverted workpiece 4 and force the workpiece 4 to flip to a correct posture.

[0027] In practice, the blanking device 2 includes a drive cylinder 21, a crossbar 22, and several parallel, spaced-apart rod-shaped members 23. In this embodiment, three rod-shaped members 23 are provided. The rod-shaped members 23 are fixedly connected to the crossbar 22. The top rod of the drive cylinder 21 is movably connected to the crossbar 22, which is used to overlap or separate the rod-shaped members 23 from the tail end of the feeding device 1. When the drive cylinder 21 is in operation, it can drive the crossbar 22 and the rod-shaped members 23 to move up and down, so that the upper end of the rod-shaped members 23 and the tail end of the feeding device 1 are overlapped or separated. In the separated state, the gap between the two is larger than the width of the workpiece 4, facilitating the smooth passage of the workpiece 4. In the overlapped state, the rod-shaped members 23 serve as a blanking channel to guide the workpiece 4 to slide to the designated position. This design enables the automatic blanking of the workpiece 4, reducing the need for manual intervention and improving production efficiency. At the same time, the inclined rod-shaped members 23 help to mitigate the impact force of the workpiece 4 when it falls, protecting the surface of the workpiece 4 from damage.

[0028] In actual application, the driving cylinder 21 and the cylinder device 3 are both electrically connected to the controller, and the movement of the cylinder is controlled by a preset program.

[0029] In actual applications, the feeding and receiving device for the production of crawler iron tooth workpieces also includes a thermometer as a safety monitoring system. The thermometer is installed above the feeding device 1 through a bracket (not shown in the drawings) and is electrically connected to the controller for real-time monitoring of the workpiece 4 temperature and feeding back the data to the controller. The controller determines and processes the workpiece 4 based on a preset temperature threshold (800°C) to ensure the safety of the workpieces 4 during processing. Specifically, when the controller detects that the temperature of a workpiece 4 is below 800°C, it sends a signal to the drive cylinder 21. The drive cylinder 21 then pushes the crossbar 22 via the push rod, separating the three rod-shaped members 23 from the rear end of the feeder 1. When unqualified workpieces 4 reach the rear end of the feeder 1, they fall directly downward through the gap between the three rod-shaped members 23 and the feeder 1 due to their own gravity. Conversely, when qualified workpieces 4 reach the rear end of the feeder 1, they slide forward and downward through the three rod-shaped members 23 to the designated position. The controller in this embodiment can be a PLC controller.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of the present invention patent.

[0031] In order to make it easier for ordinary technicians in this field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and for the sake of clarity, some other elements are omitted in this application document. Ordinary technicians in this field should realize that these omitted elements may also constitute the content of the present invention.
