Description

Technical Field

[0001] The present application relates to the technical field of sliding bearing processing, and in particular to a stamping device for sliding bearing processing. Background Art

[0002] During the processing of sliding bearings, some parts need to be stamped. The stamping process can process raw materials such as plates and strips into parts of required shapes and sizes through molds. Stamping technology has the advantages of high production efficiency, high material utilization rate, and simple operation. In the manufacturing process, the use of stamping technology can further improve production efficiency, reduce production costs, and ensure product quality and precision.

[0003] Patent No. CN 220346971 U discloses a stamping device for processing sliding bearings, including a stamping support plate, a fixing rod, a sliding bearing placement plate and a material guide inclined plate, etc. After the stamping is completed, the stamping support plate can rotate together with the rotating rod, so that the stamping support plate can be tilted as a whole, so that the sliding bearing inside the stamping groove can be poured out, and the material can be guided through the material guide inclined plate, so as to facilitate the discharge of the sliding bearing. When the lifting plate slides upward, the lifting plate drives the connecting rod to move together, so that the connecting rod can pull the stamping support plate to rotate, and the sliding bearing inside the stamping groove can be discharged. The motor drives the turntable to rotate at a constant speed through the rotating shaft, so that the push-pull rod can repeatedly push and pull the lifting plate to move, so that the stamping head can be repeatedly stamped, and the stamping support plate can be repeatedly driven to rotate, and the sliding bearing inside the stamping groove can be repeatedly discharged, thereby realizing a continuous stamping process.

[0004] However, in use, there are the following defects:

[0005] Although the stamping pallet can be tilted driven by the lifting plate and the connecting rod to export the stamped bearing, in order to ensure stable placement of the bearing during the stamping process, there will be protrusions on the edge of the sliding bearing placement plate for limiting. The inclination angle of the stamping pallet is limited, and the bearing may not be able to cross the protrusion and slide out, resulting in stagnation of material discharge and affecting the efficiency of subsequent stamping. Utility Model Content

[0006] The purpose of the present application is to provide a stamping device for processing sliding bearings, which solves the problem raised in the background technology that although the stamping support plate can be tilted under the drive of the lifting plate and the connecting rod to export the stamped bearings, in order to ensure stable placement during the bearing stamping process, there will be protrusions on the edge of the sliding bearing placement plate for limiting the position, and the inclination angle of the stamping support plate is limited. The bearing may not be able to cross the protrusion and then slide out, which leads to stagnation of material discharge and affects the efficiency of subsequent stamping.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a stamping device for processing sliding bearings, comprising a base, a support frame, a support plate and a cushion block, wherein the support frame is fixedly connected to the center of the side wall of the base, a vertical groove is vertically opened on the surface of one side of the support frame facing the base, a threaded rod is vertically rotatably connected to the inner side of the vertical groove, a threaded block is threadedly connected to the surface of the threaded rod, a support plate is fixedly connected to the side wall of the threaded block, four limiting rods are fixedly connected between the bottom of the top of the support frame and the base, and the limiting rods vertically penetrate the surface of the support plate, and the base Two arc-shaped limit blocks are fixedly installed in the center of the top, and a circular groove is provided on the surface of the support plate vertically above the arc-shaped limit block, and an electric push rod is fixedly installed on the surface of the support plate on the side of the circular groove close to the vertical groove, the telescopic end of the electric push rod is fixedly connected to the push block, and the telescopic end of the electric push rod faces the side of the circular groove, the left and right inner walls of the circular groove are fixedly connected with vertical blocks, and a pad is fixedly connected between the two vertical blocks, a side groove is provided on the surface of the pad away from the electric push rod, and a spring is fixedly connected to the inner wall of the side groove, and the other end of the spring is fixedly connected to the side wall of the arc block.

[0008] In this technical solution, the bottom of the support plate is fitted with the base before stamping, and the pad is located between the two arc-shaped limit blocks and fits firmly and has just the right size. The vertical block slides into the gap between the two arc-shaped limit blocks to form a completed ring, which is convenient for the placement and limitation of the bearing. After the placement is completed, the hydraulic cylinder is started and extended downward, thereby carrying the stamping part to stamp the bearing below, so that it remains stable during the stamping process. The support plate, threaded rod, threaded block, electric push rod and push rod can facilitate the discharge of materials after stamping. After the stamping is completed, the motor is started to drive the threaded rod to rotate, so that the threaded block and the support plate rise together. During the rising process, the support plate will rise with the pad and the bearing on its surface until it is completed. The arc limit block is completely removed from the machine, and then the electric push rod is started and extended, driving the push block to push toward the circular groove, thereby pushing the bearing to the discharge groove and finally completing the discharge. The whole process not only ensures the limitation and placement of the bearing by the arc limit block during the stamping process, but also avoids the obstruction of the arc limit block during the discharge process, thereby improving the discharge efficiency and practicality of the device. At the same time, the pad block, side groove, spring and arc block can assist the discharge of the bearing. After the pad block leaves the arc limit block, the arc block in the side groove will slide out of the side groove due to the lack of obstruction under the push of the elastic force of the spring, thereby blocking the gap between the pad block and the circular groove, avoiding the bearing being tripped by the gap during the discharge process, ensuring the smooth discharge process, and improving the practicality of the device.

[0009] As an optional solution of the technical solution of the present application, the gap between the cushion block and the circular hole matches the arc-shaped limit block below, and the gap between the two arc-shaped limit blocks matches the size of the vertical block.

[0010] As an optional solution of the technical solution of the present application, a discharge groove is provided on the edge of one side of the support plate away from the support frame, and a storage groove is provided on the edge of the base directly below the discharge groove.

[0011] As an optional solution of the technical solution of the present application, a hydraulic cylinder is fixedly installed on the top of the support frame directly above the circular groove, and the telescopic end of the hydraulic cylinder passes through the support frame and is fixedly connected to the stamping block.

[0012] As an optional solution of the technical solution of the present application, a motor is fixedly installed on the top of the support frame directly above the threaded rod, and the output end of the transmission shaft of the motor is fixedly connected to the top of the threaded rod below.

[0013] As an optional solution of the technical solution of the present application, the surface of the limit rod is fixedly sleeved and connected to the limit ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can facilitate the discharge of materials after stamping through the support plate, threaded rod, threaded block, electric push rod and push rod. After the stamping is completed, the motor is started to drive the threaded rod to rotate, so that the threaded block and the support plate rise together. During the rising process, the support plate will rise with the cushion block and the bearing on its surface until it completely leaves the arc limit block. Then the electric push rod is started and extended, driving the push block to push the circular groove, thereby pushing the bearing to the discharge groove to finally complete the discharge. In the whole process, it not only ensures the limiting and placement of the bearing by the arc limit block during the stamping process, but also avoids the obstruction of the arc limit block during the discharge process, thereby improving the discharge efficiency and practicality of the device.

[0016] 2. The present application can assist the discharging of bearings through pads, side grooves, springs and arc blocks. After the pads leave the arc limit blocks, the arc blocks in the side grooves will slide out of the side grooves due to the lack of obstruction and the elastic force of the springs, thereby blocking the gap between the pads and the circular grooves, preventing the bearings from being caught in the gap during the discharging process, ensuring the smooth discharging process and improving the practicability of the device.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, a stamping device for sliding bearing processing includes a base 1, a support frame 2, a support plate 6 and a cushion block 7. The support frame 2 is fixedly connected to the center of the side wall of the base 1, and a hydraulic cylinder 9 is fixedly installed on the top of the support frame 2 just above the circular groove 11. The telescopic end of the hydraulic cylinder 9 passes through the support frame 2 and is fixedly connected to the stamping block 901.

[0025] like Figure 2 As shown, an electric push rod 8 is fixedly installed on the surface of the support plate 6 on the side of the circular groove 11 close to the vertical groove 3. The telescopic end of the electric push rod 8 is fixedly connected to the push block 801, and the telescopic end of the electric push rod 8 is facing the side of the circular groove 11. After the electric push rod 8 is started, it will drive the push block 801 to move, pushing the bearing to perform the discharge operation.

[0026] like Figure 2 As shown, a vertical groove 3 is vertically opened on the surface of one side of the support frame 2 facing the base 1, and a threaded rod 4 is vertically rotatably connected to the inner side of the vertical groove 3. A motor 401 is fixedly installed on the top of the support frame 2 just above the threaded rod 4, and the output end of the transmission shaft of the motor 401 is fixedly connected to the top of the threaded rod 4 below. A threaded block 5 is threadedly connected to the surface of the threaded rod 4, and a support plate 6 is fixedly connected to the side wall of the threaded block 5. Four limit rods 12 are fixedly connected between the bottom of the top of the support frame 2 and the base 1, and the limit rods 12 vertically penetrate the surface of the support plate 6. The limit rods 12 keep the support plate 6 horizontal and stable during the lifting process.

[0027] like Figure 2As shown, a side surface of the cushion block 7 away from the electric push rod 8 is provided with a side groove 701, and the inner wall of the side groove 701 is fixedly connected with a spring 702, and the other end of the spring 702 is fixedly connected to the side wall of the arc block 703. The arc block 703 can block the gap between the circular groove 11 and the cushion block 7, thereby avoiding affecting the discharge of the bearing.

[0028] like Figure 2 and Figure 3 As shown, the left and right inner walls of the circular groove 11 are fixedly connected with vertical blocks 10, and a cushion block 7 is fixedly connected between the two vertical blocks 10. The gap between the cushion block 7 and the circular hole matches the arc-shaped limit block 13 below, and the gap between the two arc-shaped limit blocks 13 matches the size of the vertical block 10. The arc-shaped limit block 13 cooperates with the vertical block 10 to form a complete ring, thereby ensuring the limitation of the bearing.

[0029] like Figure 2 and Figure 4 As shown, a discharge groove 601 is provided on the edge of one side of the support plate 6 away from the support frame 2, and a storage groove 101 is provided on the edge of the base 1 directly below the discharge groove 601. When the support plate 6 is in contact with the base 1, the discharge groove 601 is located on the inner side of the storage groove 101, so as to avoid the obstruction of the discharge groove 601 causing the support plate 6 to be unable to be lowered to the lowest level.

[0030] like Figure 3 As shown, the surface of the limiting rod 12 is fixedly sleeved and connected to a limiting ring 121 , and the limiting ring 121 can stop the support plate 6 to prevent it from rising too high and hitting the stamping block 901 .

[0031] like Figure 3 and Figure 4 As shown, two arc-shaped limit blocks 13 are fixedly installed at the center of the top of the base 1, and a circular groove 11 is formed on the surface of the support plate 6 vertically above the arc-shaped limit blocks 13.

[0032] In this technical solution, the bottom of the support plate 6 fits with the base 1 before stamping, and the pad is located between the two arc-shaped limit blocks 13, and fits firmly and has just the right size. The vertical block 10 just slides into the gap between the two arc-shaped limit blocks 13 to form a completed ring, thereby facilitating the placement and limiting of the bearing. After the placement is completed, the hydraulic cylinder 9 is started and extended downward, thereby carrying the stamping part to stamp the bearing below, so that it remains stable during the stamping process. After the stamping is completed, the motor 401 is started, driving the threaded rod 4 to rotate, so that the threaded block 5 and the support plate 6 rise together. During the rising process, the support plate 6 will rise with the pad 7 and the bearing on its surface until it completely leaves the arc-shaped limit block 13. , and then the electric push rod 8 starts and extends, driving the push block 801 to push toward the circular groove 11, thereby pushing the bearing to the discharge groove 601 and finally completing the discharge. During the whole process, the arc limit block 13 is guaranteed to limit and place the bearing during the stamping process, and the obstruction of the arc limit block 13 during the discharge process is avoided, thereby improving the discharge efficiency and practicality of the device. After the cushion block 7 leaves the arc limit block 13, the arc block 703 in the side groove 701 will slide out of the side groove 701 due to the lack of obstruction under the elastic force of the spring 702, thereby blocking the gap between the cushion block 7 and the circular groove 11, avoiding the bearing being tripped by the gap during the discharge process, ensuring the smooth discharge process, and improving the practicality of the device.
