Description

Technical Field

[0001] The utility model relates to the field of heat treatment of forgings, in particular to a feeding device for quenching stainless steel forgings. Background Art

[0002] Quenching is a heat treatment process in which steel is heated to above its critical temperature, held at that temperature for a specified period, and then cooled at a rate greater than the critical cooling rate, thereby achieving an unbalanced structure dominated by martensite. Quenching is the most widely used process in steel heat treatment.

[0003] In the prior art, there are generally two ways to quench small stainless steel forgings after they are forged: the first is to manually place them into the quenching equipment for quenching, and after the quenching is completed, they are also manually taken out with the help of tools. In this way, the labor intensity of the operator is relatively high. The second is that the robot places the forging into the quenching equipment for quenching, and after the quenching is completed, it is also taken out by the robot. In this way, under normal circumstances, the robot grabs the forgings individually. In order to improve the quenching efficiency, the robot may grab multiple products at a time and put them into the quenching equipment. However, conventional feeding conveyor lines are equipped with obstructions at the ends. Therefore, when the robot grabs the material, it first grabs the product at the end and waits for the next product to move to the end before grabbing it. In this way, the grabbing efficiency will be a little lower, which affects the heat treatment efficiency. Summary of the Invention

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: See Figure 1-4 As shown, a feeding device for quenching stainless steel forgings comprises a frame 1 and a conveyor line 2 arranged on the frame 1, the frame 1 is further provided with at least two sets of laterally spaced blocking mechanisms 3, the blocking mechanism 3 comprises a bracket 4, a blocking member 5 and a cylinder 6, the bracket 4 is mounted on the front end surface of the frame 1, the blocking member 5 is longitudinally slidably arranged on the bracket 4, the moving direction of the blocking member is perpendicular to the moving direction of the top of the conveyor line, the bottom plane of the rear end of the blocking member 5 is arranged above the top plane of the conveyor line 2, the cylinder 6 is mounted on the bracket 4, and the rear end of the blocking member 5 is provided with a blocking groove 7;

[0032] A limit plate 8 is provided on the frame 1, and the limit plate 8 is set just above the conveyor line 2 at the rear end of the material blocking member 5. The cylinder 6 is configured to drive the material blocking member 5 to move forward and backward, so that the material blocking member 5 is close to or away from the limit plate 8.

[0033] In this embodiment, taking the top of the conveyor line moving from left to right as an example, the product is placed on the top of the conveyor line and conveyed to the right. A photoelectric sensor can be set on the frame to detect the number of products conveyed to the right. For example, two sets of blocking mechanisms are provided. When two products move to the left side of the corresponding blocking mechanism in turn, the output shaft of the cylinder extends, driving the blocking member to move backward, blocking the product through the blocking groove, and pushing the product to move backward close to the limit plate or contact with the limit plate, so that the product will be stably pushed to the predetermined position. The subsequent manipulator moves to the top of the conveyor line at this position to quickly grab the product and grab it into the quenching equipment for quenching. In this embodiment, the corresponding working number of blocking mechanisms is selected according to the number of products that can be quenched at a time in the quenching equipment, and can quickly position at a predetermined position for at least one group or multiple products at the same time, so that the manipulator can quickly grab multiple products at the same time and put them into the quenching equipment for rapid quenching, thereby improving quenching efficiency.

[0034] At the same time, in this embodiment, a limit plate is also provided, and the width of the conveyor line will be greater than the width of the product. In order to ensure that the product moves to the right and can be accurately positioned in a position to facilitate the subsequent rapid grasping of the robot (that is, when the robot grasps the material, there is no need for secondary positioning and grasping, thereby improving the grasping efficiency), through the provision of the limit plate, when the cylinder output shaft extends, the material blocking member moves backward through the material blocking groove to drive the limited product to move backward to the corresponding position. In this way, when the front-end product is unloaded and conveyed, there is no need for precise alignment, which improves the convenience of unloading at the front end, and can convey products within a certain size range, with a wider range of applications. Furthermore, the limit plate can adjust the front and rear positions to accommodate products of different sizes.

[0035] See also Figure 3 、 4 As shown, the material blocking member 5 includes a longitudinal slide rail 9 and an L-shaped material blocking plate 10. A longitudinal slide groove 11 is provided on the side wall of the bracket 4. The longitudinal slide rail 9 is slidably connected to the longitudinal slide groove 11.

[0036] The front end of the L-shaped baffle plate 10 is connected to the longitudinal slide rail 9, and the baffle groove 7 is arranged at the rear end of the L-shaped baffle plate 10. The cylinder 6 is configured to drive the longitudinal slide rail 9 and the L-shaped baffle plate 10 to move longitudinally along the longitudinal slide groove 11.

[0037] In this embodiment, the L-shaped material baffle plate is installed on the longitudinal slide rail, and the L-shaped material baffle plate is slidably connected through the longitudinal slide rail and the longitudinal slide groove. The cylinder is used to drive the L-shaped material baffle plate and the longitudinal slide rail to slide along the longitudinal slide groove to realize the forward and backward movement of the material baffle groove.

[0038] See also Figure 4 As shown, the L-shaped baffle plate 10 includes a longitudinal plate 12 and a transverse plate 13. The front end of the longitudinal plate 12 is connected to the side wall of the longitudinal slide rail 9, and the right end of the transverse plate 13 is connected to the left side of the middle part of the longitudinal plate 12. The rear side of the transverse plate and the left side of the longitudinal plate constitute the baffle groove;

[0039] The bottom planes of the longitudinal plates and the transverse plates are arranged above the top plane of the conveying line.

[0040] In this embodiment, the longitudinal plate is arranged parallel to the longitudinal slide rail, and the transverse plate is arranged perpendicular to the longitudinal slide rail and the longitudinal plate. A material blocking groove is formed between the transverse and longitudinal plates. The longitudinal plate can prevent the product from moving to the right. When the transverse plate moves backward, it can push the product backward to move closer to the limit plate, thereby blocking the product and facilitating subsequent grasping by the robot. In addition, the L-shaped material blocking plate structure uses less material, thereby reducing material consumption and costs.

[0041] See also Figure 4As shown, there is a vertical plate 14 extending downward at the bottom of the longitudinal plate 12, and the vertical plate 14 is arranged at the front end of the frame 1, and the cylinder 6 is connected to the vertical plate 14; when the blocking member 5 moves backward, the vertical plate 14 is arranged close to the frame 1, or the vertical plate 14 is against the front end surface of the frame 1.

[0042] The vertical plate facilitates the connection between the cylinder and the material stop, allowing the cylinder to be placed below the longitudinal slide rail without increasing the longitudinal space occupied. When the cylinder output shaft is extended, the material stop is placed close to the frame and has a certain distance between them so that the two do not contact each other.

[0043] See also Figure 4 As shown, a slope 15 is further provided on the left side of the rear end of the longitudinal plate 12. The slope is tilted from the back to the front and to the left. The slope is provided on the rear side of the transverse plate.

[0044] This embodiment is primarily used for quenching and feeding cylindrical products. If two products are adjacent, a bevel is provided on the left side of the rear end of the longitudinal plate to ensure that the stopper can separate the two products. When the longitudinal plate moves backward, the bevel first contacts the product and acts as a guide, allowing the longitudinal plate to be smoothly inserted into the right side of the product, allowing the product to enter the stopper groove and be pushed backward toward the limit plate or contact the limit plate.

[0045] See also Figure 1-3 As shown, a support frame 16 is further provided, and the frame 1 is mounted on the support frame 16;

[0046] The frame 1 includes a front side plate 17 and a rear side plate 18, the conveyor line 2 is arranged between the front side plate 17 and the rear side plate 18, and the two ends of the conveyor line 2 are respectively connected to the front side plate 17 and the rear side plate 18;

[0047] The limiting plate is installed on the top of the rear side plate, and the bracket is installed on the front end surface of the front side plate.

[0048] In this embodiment, the conveyor line is composed of multiple chain plates connected in sequence to form a closed loop structure, which is internally provided with a driving shaft and a driven shaft. The two ends of the driving shaft and the driven shaft are respectively connected to the front side plate and the rear side plate for rotation. The chain plates are located between the front side plate and the rear side plate. Sprockets are respectively provided on the driving shaft and the driven shaft. The chain plates are wound around the sprockets of the driving shaft and the driven shaft. A motor is also provided on the front side plate or the rear side plate to drive the driving shaft, thereby realizing the drive of the conveyor line. The support frame is provided to lift the frame off the ground.

[0049] See also Figure 1-3 As shown, two extension plates 19 are further provided, each of which is mounted on the bottom of the front side plate 17 and the rear side plate 18 respectively;

[0050] The support frame 16 is connected to the two extension plates 19 via at least two sets of connecting members 20;

[0051] The connecting member 20 has a through slot 21 extending through its center and extending through its ends. Multiple groups of these connecting members are arranged transversely and spaced apart. The bottom of each connecting member is connected to the support frame, and the top of each connecting member is connected to the two extension plates. The extension plates facilitate the connection of the connecting member to the corresponding front or rear side panels and increase the contact area between the front and rear side panels and the connecting member, thereby enhancing strength.

[0052] In this embodiment, the support frame adopts an I-shaped structure, which uses less material. It is connected to the front side plate and the rear side plate through two sets of connecting parts, so that the conveyor line can be raised, thereby reducing material consumption. In addition, support frames of different heights can be selected according to different occasions to increase the scope of application and reduce costs.

[0053] See also Figure 1-3 As shown, a U-shaped plate 22 is further provided, and the U-shaped plate 22 is arranged directly below the conveyor line 2. There is a vertical spacing between the U-shaped plate 22 and the extension plate 19, and the middle part of the U-shaped plate 22 is inserted into the through grooves 21 of multiple groups of the connecting parts 20, and the bottom of the U-shaped plate 22 is against the bottom surface of the through groove 21.

[0054] In this embodiment, the product is a stainless steel forging, and there may be some oxide scale or other debris on its outer surface. Therefore, during its transportation process, some debris on its surface will fall onto the conveyor line. Under normal circumstances, it will fall to the ground as the conveyor line rotates. If it is just a simple dust layer, it is easy to clean, but some metal impurities that fall are not easy to clean and are likely to damage and destroy the ground. Therefore, through the setting of the U-shaped plate, the debris that falls on the conveyor line will fall into the U-shaped groove on the top of the U-shaped plate and be collected by the U-shaped plate. When cleaning later, you only need to clean the U-shaped groove of the U-shaped plate, which is convenient for quick cleaning. The connector adopts a structure with a through groove inside, which facilitates the rapid installation and disassembly of the U-shaped plate, and can also limit it to prevent the U-shaped plate from falling out of the through groove.

[0055] See also Figure 2 As shown, a support plate 23 extending upward is provided at the bottom of each through slot 21 , and the bottom of the U-shaped plate 22 rests on the support plate 23 .

[0056] The support plate can slightly elevate the bottom of the U-shaped plate, bringing it closer to the conveyor line. This reduces the distance between the conveyor line and the U-shaped plate, and reduces the noise and impact when debris falls onto the U-shaped plate. More preferably, bolts can be used to secure the U-shaped plate to the support plate, ensuring that the U-shaped plate is stably mounted on the support plate and prevents it from falling within the slots of the connector, making it more stable to use.
