Description

Technical Field

[0001] The invention relates to the field of forging, in particular to a sorting mechanism suitable for crawler iron tooth workpieces. Background Art

[0002] like Figure 1 The track tooth component shown in the figure consists of a flat rectangular block with two spaced-apart protruding teeth in the middle. The protruding teeth are connected to the block by a small arc. Due to the complex shape of the component and the large abrupt changes in cross-section, the metal deformation varies from part to part, making residual heat treatment difficult.

[0003] The traditional heat treatment method involves heating the workpiece after it has been formed. Years of technological advancements have made it possible to utilize the residual heat from forging for heat treatment. However, the residual temperature of the workpiece after trimming must be greater than 800°C before it can be placed in the residual heat quenching tank for residual heat quenching. If it is below 800°C, residual heat quenching cannot be performed, as this will affect the quenching effect. Therefore, the temperature of each workpiece must be measured before residual heat quenching. Workpieces with a temperature greater than 800°C are transferred to the residual heat quenching tank, while those with a temperature below 800°C are removed for reheating.

[0004] However, due to the complex shape and irregular structure of the track tooth parts, the shapes of the workpieces after cutting and falling off are different. It is impossible to accurately measure the temperature of each workpiece during the transportation process. If the temperature measurement is inaccurate, it is impossible to sort them, and if sorting is not possible, the product quality cannot be guaranteed. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and to provide a sorting mechanism suitable for track iron tooth workpieces, which can accurately sort the workpieces according to temperature.

[0006] The technical solution of the method of the present invention is: a sorting mechanism suitable for crawler iron tooth workpieces, the workpiece includes a flat rectangular parallelepiped with two spaced convex teeth in the middle part of the rectangular parallelepiped, the sorting mechanism includes a material receiving device, a feeding device, a blanking device, a thermometer and a controller; the feeding device includes two parallel conveyor chains and a round rod located between the two conveyor chains, and the outer sides of the two conveyor chains are provided with chain mounting plates; the material receiving device is installed at the front end of the feeding device and has a buffering function; the blanking device includes a driving cylinder, three parallel and spaced rod-shaped members and a cross bar, the three rod-shaped members are all in an inclined state and are all fixedly installed on the same cross bar, the top rod of the driving cylinder is movably connected to the cross bar, and under the action of the driving cylinder, the upper ends of the three rod-shaped members can overlap or separate with the tail end of the feeding device, and when the two are in a separated state, the gap between the two is greater than the width of the workpiece; the thermometer is installed above the feeding device through a bracket, and the thermometer and the driving cylinder are both electrically connected to the controller.

[0007] In one embodiment, the material receiving device includes two L-shaped plates and a connecting plate. The two L-shaped plates are respectively installed on the outside of the two chain mounting plates through pins. The two L-shaped plates can be divided into a front section and a rear section with their respective pin holes as boundaries. The connecting plate is located below the two chain mounting plates and is fixedly connected to the ends of the rear sections of the two L-shaped plates. Under the action of gravity of the connecting plate and the rear sections of the two L-shaped plates, the front sections of the two L-shaped plates are tilted upward around the pins and partially protrude from the upper surface of the conveying chain.

[0008] Furthermore, a transverse limiting rod is provided above the middle section of the feeding device.

[0009] In one embodiment, the two conveyor chains of the feeding device are driven by a motor through a sprocket.

[0010] In one embodiment, the round rod of the feeding device is a hollow rod.

[0011] The sorting mechanism provided by the present invention has the following beneficial effects:

[0012] 1) The buffer function of the receiving device is used to ensure the consistency of the shape of the workpiece after it falls;

[0013] 2) The round rod in the middle of the feeding device ensures that all workpieces can be conveyed in the same form, that is, the two protruding teeth of the workpiece can just clamp the round rod and move under the drive of the conveyor chain;

[0014] 3) Since the workpieces on the feeding device are arranged in a regular and uniform manner, it is beneficial for the thermometer to accurately measure the temperature of each workpiece;

[0015] 4) Since the thermometer and the driving cylinder are both electrically connected to the controller, the thermometer will instantly transmit each temperature measurement result to the controller. When the controller receives that the temperature of a workpiece is lower than 800℃, the controller will send a signal to the driving cylinder. The driving cylinder will push the cross bar through the push rod to separate the three rod-shaped members from the tail end of the feeding device. When the unqualified workpiece is transported to the tail end of the feeding device, it will fall directly from the gap between the three rod-shaped members and the feeding device due to its own gravity; on the contrary, the three rod-shaped members will overlap with the tail end of the feeding device. When the qualified workpiece is transported to the tail end of the feeding device, it will directly slide forward and downward through the three rod-shaped members to the residual heat quenching tank.

There are three rod-shaped members 32 and a cross bar 33 arranged in rows and at intervals. The three rod-shaped members 32 are all in an inclined state and are fixedly mounted on the same cross bar 33. The top rod of the driving cylinder 31 is movably connected to the cross bar 33. Under the action of the driving cylinder 31, the upper ends of the three rod-shaped members 32 can overlap or separate from the tail end of the feeding device 20. When the two are in a separated state, the gap between them is greater than the width of the workpiece; the thermometer 40 is installed above the feeding device 20 through a bracket, and the thermometer 40 and the driving cylinder 31 are electrically connected to the controller; a horizontal limit rod 60 is also provided above the middle section of the feeding device 20, which can intercept the inverted workpiece 50 and force the workpiece 50 to flip to the correct posture.

[0031] The material receiving device 10 includes two L-shaped plates 11 and a connecting plate 12. The two L-shaped plates 11 are respectively installed on the outside of the two chain mounting plates through pins. The two L-shaped plates 11 can be divided into a front section and a rear section with their respective pin holes as boundaries. The connecting plate 12 is located below the two chain mounting plates and is fixedly connected to the ends of the rear sections of the two L-shaped plates 11.
