Description

Technical Field

[0001] This utility model relates to the field of piston pin processing technology, specifically a multi-functional blanking machine for piston pin production. Background Technology

[0002] A piston pin is a cylindrical pin installed on the piston skirt. Its center passes through the connecting rod small end hole to connect the piston and the connecting rod, transmitting the gas force on the piston to the connecting rod. It is generally made of high-quality alloy steel and is hollow. In actual production of piston pins, a cutting device is needed to cut the alloy steel. During this process, a feeding device is needed to complete the feeding of the alloy steel. In actual use, it has the advantages of simple operation, stable structure and good performance.

[0003] Publication number CN222289490U discloses a feeding device for piston pin production. Through a concave plate, it can stably guide alloy steel materials of various sizes without affecting the feeding process, thus ensuring stable feeding of alloy steel materials for piston pin production. However, this patent still has the following problems in practical use:

[0004] The concave plate allows for stable guidance of alloy steel materials of various sizes without affecting the material feeding process, ensuring stable feeding of alloy steel materials for piston pin production. However, during piston pin production, the raw materials need to be cut to facilitate subsequent piston pin manufacturing. The aforementioned device, however, cannot provide a limiting and positioning function for the raw materials during cutting, making it inconvenient when cutting the raw materials into different equal parts, thus increasing the likelihood of errors.

[0005] A multi-functional blanking machine for piston pin production is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-functional blanking machine for piston pin production, to solve the problem mentioned in the background art. While the existing device uses a concave plate to stably guide alloy steel materials of various sizes without affecting the material feeding, ensuring stable feeding of alloy steel materials for piston pin production, the raw materials need to be cut during piston pin production to facilitate subsequent manufacturing. However, the aforementioned device cannot provide a limiting and positioning function for the raw materials during cutting, making it inconvenient when cutting the raw materials into different equal parts, thus increasing the likelihood of errors.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional unloading machine for piston pin production, including a processing table, wherein a collection box is provided on one side of the bottom surface of the processing table;

[0008] A conveying device is fixedly installed on one side surface of the processing table, a stabilizing frame is fixedly installed on the top surface of the processing table, a cylinder is fixedly installed in the middle of the top surface of the stabilizing frame, a cutting device is provided on the bottom surface of the cylinder, and a protective cover is fixedly installed in the middle of the top surface of the processing table.

[0009] Also includes:

[0010] A sliding groove is provided on one side of the interior of the processing table, and a blocking component is provided inside the sliding groove.

[0011] The blocking component includes a sleeve rod that is fixedly connected to the sliding groove;

[0012] A return spring is fitted onto the surface of the sleeve rod.

[0013] Preferably, one side surface of the reset spring is fixedly connected to the groove, and the other side surface of the reset spring is fixedly connected to a baffle. A movable groove is provided on one side of the inside of the baffle, and the movable groove is slidably connected to the sleeve rod.

[0014] Preferably, a connecting frame is attached to both sides of the surface of the baffle. The side of the connecting frame away from the baffle is fixedly connected to the base. A limiting rod is connected through the middle of the inside of the connecting frame. A tension spring is sleeved on the surface of the limiting rod. One side of the tension spring is fixedly connected to the limiting rod, and the other side of the tension spring is fixedly connected to the connecting frame.

[0015] Preferably, a plurality of limiting grooves are symmetrically provided on both sides of the moving groove, and the limiting grooves are engaged with the limiting rods.

[0016] Preferably, the bottom surface of the processing table is provided with symmetrical grooves on both sides, and a slider is slidably connected inside the groove. The side surface of the slider away from the groove is fixedly connected to the collection box.

[0017] Preferably, telescopic rods are symmetrically installed on both sides of the cutting device, a compression spring is sleeved on the surface of the telescopic rod, a pressure plate is fixedly connected to the bottom surface of the compression spring, the top surface of the compression spring is fixedly connected to the cutting device, and the bottom surface of the telescopic rod is fixedly connected to the pressure plate.

[0018] Preferably, the top surface of the protective cover has a hole in the middle.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-functional blanking machine for piston pin production, by setting a blocking component, can block the end of the piston pin raw material, thereby allowing the piston pin raw material to be cut to different lengths indirectly by adjusting the distance between the blocking component and the processing table. The specific details are as follows:

[0020] 1. By setting up a blocking component, after the piston pin raw material is moved to the processing table by the conveying device, the position of the baffle on the blocking component is adjusted as needed. When adjusting the position of the baffle, the limiting rod is pulled to separate the limiting rod from the limiting groove. Then, by pulling or pushing the baffle, the baffle can be moved to the right or left as needed. When the baffle moves to the right, it will compress the return spring. When the baffle moves to the left, it will stretch the return spring. This allows the baffle to be adjusted according to the actual situation. After the baffle is adjusted to the appropriate position, the limiting rod is loosened, and the limiting rod engages with the limiting groove under the action of the stretching spring. This limits the position of the baffle and ensures its stability. This allows the piston pin raw material to be cut into different lengths, thereby improving the practicality and flexibility of the device.

[0021] 2. By setting up a cylinder, cutting device, protective cover, telescopic rod, compression spring, clamping plate, and holes, after the piston pin raw material is conveyed to the processing table, one end of the piston pin raw material abuts against the baffle. At this time, the cylinder is activated by the control end, so that the output end of the cylinder can drive the cutting device to descend. The descent of the cutting device can drive the telescopic rod, compression spring, and clamping plate to descend. At the same time, the length of the clamping plate is longer than the cutting device, and the bottom surface of the clamping plate is arc-shaped. This means that when the cutting device cuts the piston pin raw material, the clamping plate squeezes the piston pin raw material, which in turn causes the telescopic rod and compression spring to... The compression process causes the telescopic rod and compression spring to deform. Simultaneously, the compression spring applies pressure to the clamping plate, ensuring the piston pin material is held in place during cutting and preventing any deviation. The protective cover also shields the material from debris generated during cutting, preventing injury. The debris falls through holes in the processing table into a collection box. Holes are also provided on the top center and both sides of the bottom surface of the protective cover to facilitate the movement of the piston pin material and the descent of the cutting device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a multi-functional unloading machine for piston pin production, including a processing table 1, a collection box 2 provided on one side of the bottom surface of the processing table 1; a conveying device 3 fixedly installed on one side surface of the processing table 1, a stabilizing frame 4 fixedly installed on the top surface of the processing table 1, a cylinder 5 fixedly installed in the middle of the top surface of the stabilizing frame 4, a cutting device 6 provided on the bottom surface of the cylinder 5, and a protective cover 7 fixedly installed in the middle of the top surface of the processing table 1; it also includes: a sliding groove 10 opened on one side of the interior of the processing table 1, and a blocking component 11 provided inside the sliding groove 10; wherein, the blocking component 11 includes a sleeve rod 1101 fixedly connected to the sliding groove 10; wherein, a return spring 1102 is sleeved on the surface of the sleeve rod 1101, such as Figure 1-5As shown, by setting the blocking component 11, the end of the piston pin raw material can be blocked, thereby allowing the piston pin raw material to be cut to different lengths indirectly by adjusting the distance between the blocking component 11 and the processing table 1. At the same time, the conveying device 3 is a conveyor belt in the prior art and its working principle is the same as that of the prior art. The cutting device 6 is also in the prior art and its working principle is the same as that of the prior art.

[0030] One side surface of the return spring 1102 is fixedly connected to the groove, and the other side surface of the return spring 1102 is fixedly connected to the baffle 1103. A moving groove 1104 is formed on one side of the baffle 1103, and the moving groove 1104 is slidably connected to the sleeve rod 1101. Connecting frames 1105 are attached to both sides of the surface of the baffle 1103. The side surface of the connecting frame 1105 away from the baffle 1103 is fixedly connected to the base. A limiting rod 1106 is connected through the middle of the interior of the connecting frame 1105. A tension spring 1107 is sleeved on the surface of the limiting rod 1106. One side surface of the tension spring 1107 is fixedly connected to the limiting rod 1106, and the other side surface of the tension spring 1107 is fixedly connected to the connecting frame 1105. Several limiting grooves 1108 are symmetrically formed on both sides of the moving groove 1104, and the limiting grooves 1108 are engaged with the limiting rods 1106. Figure 3 , 4 As shown, by pulling the limiting rod 1106, the limiting rod 1106 is separated from the limiting groove 1108. Then, by pulling or pushing the baffle 1103, the baffle 1103 can move to the right or left as needed. When the baffle 1103 moves to the right, it compresses the return spring 1102. When the baffle 1103 moves to the left, it stretches the return spring 1102. This allows the baffle 1103 to be adjusted as needed. After adjusting the baffle 1103 to the appropriate position, by loosening the limiting rod 1106, the limiting rod 1106 engages with the limiting groove 1108 under the action of the tension spring 1107. This limits the position of the baffle 1103, ensuring its stability. This allows the piston pin raw material to be cut into different lengths, thereby improving the practicality and flexibility of the device.

[0031] The bottom surface of the processing table 1 is symmetrically provided with grooves 8 on both sides. A slider 9 is slidably connected inside the grooves 8. The side of the slider 9 away from the grooves 8 is fixedly connected to the collection box 2. Figure 2 As shown, the top surface of the processing table 1 is also provided with several holes 15, which allows the debris generated when cutting the piston pin raw material to fall into the collection box 2 through the holes 15, so that the collection box can collect the waste.

[0032] Telescopic rods 12 are symmetrically installed on both sides of the cutting device 6. Compression springs 13 are sleeved on the surface of the telescopic rods 12. A pressure plate 14 is fixedly connected to the bottom surface of the compression springs 13. The top surface of the compression springs 13 is fixedly connected to the cutting device 6, and the bottom surface of the telescopic rods 12 is fixedly connected to the pressure plate 14. Figure 2 As shown, the descent of the cutting device 6 causes the telescopic rod 12, compression spring 13, and pressure plate 14 to descend as well. The pressure plate 14 is longer than the cutting device 6, and its bottom surface is arc-shaped. This means that when the cutting device 6 cuts the piston pin material, the pressure plate 14 compresses the piston pin material, which in turn compresses the telescopic rod 12 and compression spring 13, causing them to deform. Simultaneously, the compression spring 13 applies pressure to the pressure plate 14, thus ensuring that the piston pin material does not shift during cutting.

[0033] A hole 15 is provided in the middle of the top surface of the protective cover 7, such as... Figure 5 As shown, the protective cover 7 can shield the debris generated during the cutting of the piston pin raw material, thereby preventing personnel injury. At the same time, the debris will fall into the collection box 2 through the holes 15 on the processing table 1. In addition, holes 15 are provided on the top middle and both sides of the bottom surface of the protective cover 7, which facilitates the movement of the piston pin raw material and the descent of the cutting device 6.

[0034] Working principle: Before using this multi-functional feeder for piston pin production, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, by setting the blocking assembly 11, after the piston pin raw material is moved to the processing table 1 by the conveying device 3, the position of the baffle 1103 on the blocking assembly 11 is adjusted as needed. When adjusting the position of the baffle 1103, the limiting rod 1106 is pulled to separate the limiting rod 1106 from the limiting groove 1108. Then, by pulling or pushing the baffle 1103, the baffle 1103 can move to the right or left as needed. When the baffle 1103 moves to the right, it will squeeze the return spring 1102. When the device moves to the left, the baffle 1103 stretches the return spring 1102, allowing the baffle 1103 to be adjusted according to the actual situation. After the baffle 1103 is adjusted to the appropriate position, the limiting rod 1106 is loosened, causing the limiting rod 1106 to engage with the limiting groove 1108 under the action of the tension spring 1107. This limits the position of the baffle 1103, ensuring its stability. This allows the piston pin material to be cut into different lengths, thereby improving the practicality and flexibility of the device.

[0035] Secondly, by setting up cylinder 5, cutting device 6, protective cover 7, telescopic rod 12, compression spring 13, clamping plate 14, and hole 15, after the piston pin raw material is transported to the processing table 1, one end of the piston pin raw material abuts against the baffle 1103. At this time, the cylinder 5 is activated by the control end, so that the output end of the cylinder 5 can drive the cutting device 6 to descend. The descent of the cutting device 6 can drive the telescopic rod 12, compression spring 13, and clamping plate 14 to descend. At the same time, the length of the clamping plate 14 is longer than that of the cutting device 6, and the bottom surface of the clamping plate 14 is arc-shaped. This means that when the cutting device 6 cuts the piston pin raw material, the clamping plate 14 squeezes the piston pin raw material, which will cause the telescopic rod to... The telescopic rod 12 and the compression spring 13 are squeezed together, causing the telescopic rod 12 and the compression spring 13 to deform. At the same time, the compression spring 13 applies a squeezing force to the clamping plate 14, so that the clamping plate 14 can clamp the piston pin raw material, thereby ensuring that the piston pin raw material will not deviate during cutting. Meanwhile, the protective cover 7 can block the debris generated during the cutting of the piston pin raw material, thereby preventing personnel injury. The debris will fall into the collection box 2 through the holes 15 on the processing table 1. The protective cover 7 has holes 15 on the top center and both sides of the bottom surface, which facilitates the movement of the piston pin raw material and the descent of the cutting device 6.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
