Description

Technical Field

[0001] This application relates to the technical field of axle head forging, and particularly to a feeding device for vehicle axle head forgings. Background Art

[0002] In the production process of vehicle axle head forgings, the automation level and operation efficiency of the feeding device directly affect the forging quality and production cost. As a key load-bearing component of the vehicle transmission system, vehicle axle heads are usually formed by hot forging process using high-strength alloy materials, with complex structures and extremely high requirements for dimensional accuracy.

[0003] Currently, the feeding of forgings mainly relies on the combination of directional conveying by a conveyor belt and coordinated pushing by two cylinders. That is, in the existing device, the first cylinder is required to push the forgings on the conveyor belt into the forging groove, and then the second cylinder pushes the forgings in the forging groove to the forging press.

[0004] In related technologies, such step-by-step operations not only require the electronic control system to synchronize the action timings of the two cylinders with high precision, but also easily lead to an increase in the failure rate due to the complex mechanical structure. If there are minor leaks or air pressure fluctuations in the drive air circuits of the two cylinders, there will be a certain difference in the propulsion speeds of the two piston rods, resulting in an increase in the positioning deviation rate of the workpieces in the forging groove. At the same time, the existing system needs to precisely control the action timings of the two cylinders through a PLC: after the first cylinder retracts, the second cylinder can start the pushing action. This serial control mode prolongs the single feeding cycle, restricts the improvement of the production line rhythm, extends the production cycle, and has high energy consumption for the repeated actions of the cylinders. Summary of the Invention

[0005] In order to solve the problems of pneumatic system instability, low efficiency, and difficult synchronous control caused by the displacement of forgings pushed by two cylinders in the existing feeding device, this application provides a feeding device for vehicle axle head forgings.

[0006] The feeding device for vehicle axle head forgings provided by this application adopts the following technical solutions: A feeding device for vehicle axle head forgings, comprising: A forging conveyor belt, on one side of which there are forging guiding grooves arranged side by side and offset. Both the forging conveyor belt and the forging guiding grooves are distributed with forgings. One side of the forging guiding groove is provided with a support plate, and the support plate is fixed on an external support structure; An X-axis pushing mechanism is used to push the forging piece to move along the X-axis direction, so that the forging piece located on the forging piece conveyor belt moves into the forging guide groove, and the X-axis pushing mechanism includes a guide rod, a docking seat and an X-axis push plate, the guide rod is slidably clamped on the support plate along the X-axis direction, the docking seat is fixed to one end of the guide rod, one end of the X-axis push plate of the L-shaped structure is fixed to the docking seat, and the other end of the X-axis push plate is located at the side of the intersection of the forging piece conveyor belt and the forging guide groove; The Y-axis pushing mechanism is used to push the forging part to move along the Y-axis direction, so that the forging part located on the forging guide groove is moved into the forging equipment. The Y-axis pushing mechanism includes a first fixed plate, a second fixed plate, a driven plate and a Y-axis pushing rod. The first fixed plate and the second fixed plate are both fixed on one side of the support plate, and the driven plate is rotatably connected to the second fixed plate. The Y-axis pushing rod of the 匚-shaped structure is slidably clamped on the support plate along the Y-axis direction, and one end of the Y-axis pushing rod is rotatably connected to the driven plate, and the other end is located on one side of the forging guide groove.

[0007] By adopting the above technical solution, the cam mechanism in the X-axis pushing mechanism and the Y-axis pushing mechanism is used to drive the linkage of the X-axis and Y-axis push rods, replacing the split cylinder structure, and realizing the timing connection of the two-axis movements through mechanical phase difference control, so that the synchronization error of the pushing and positioning of the forged parts is reduced, which is significantly better than the traditional pneumatic system, and the single power source multi-directional driving effect is realized. At the same time, the mechanical timing control of the cam-connecting rod mechanism replaces the PLC programming logic, eliminates the serial delay of the dual-cylinder action, shortens the single feeding cycle, and effectively improves the production line beat, which greatly reduces the dependence on electronic control and intensifies energy consumption at the same time. For example, the linkage mechanism realizes two-axis movement of the X-axis push plate and the Y-axis push rod through a single driving device, which is more energy-efficient than the dual-cylinder independent air circuit system, and avoids the problem of movement inaccuracy caused by air pressure fluctuations. It fundamentally solves the technical bottlenecks of the dual-cylinder system in timing synchronization, space occupancy and energy efficiency, and provides a better automatic feeding solution for the large-scale production of high-precision forgings such as vehicle axle heads.

[0008] Optionally, the X-axis driving mechanism also includes a linkage plate and a socket, the linkage plate is in a V-shaped structure, and the center of the linkage plate is rotatably connected to the support plate, the socket is fixed on the docking seat, and one end of the linkage plate is slidably connected to the socket.

[0009] By adopting the above technical solution, the rotation of the linkage plate drives the clamping seat to be linked, so that the docking seat can drive the X-axis push plate to move in a directional manner under the limiting action of the guide rod.

[0010] Optionally, the X-axis pushing mechanism further includes a first cam and a contact wheel. The first cam is rotatably connected to the support plate. The contact wheel is arranged on the linkage plate, and the contact wheel is in rolling contact with the edge of the first cam. The first cam is connected to an external driving device.

[0011] By adopting the above technical solution, the rotation of the first cam is used to push the contact wheel to roll, and at the same time drive the overall rotation of the linkage plate.

[0012] Optionally, the Y-axis pushing mechanism further includes a passive disk, a cam groove and a transmission rod. The transmission rod is rotatably connected to the first fixing plate. The passive disk is coaxially fixed to one end of the transmission rod. The cam groove is concavely arranged on the passive disk. A convex block is arranged at one end of the driven plate away from the Y-axis pushing rod, and the convex block is slidably clamped in the cam groove.

[0013] By adopting the above technical solution, the rotation of the passive disk is used to make the convex block slide in the cam groove, and the rotation of the driven plate is driven by the limiting effect of the cam groove.

[0014] Optionally, the Y-axis pushing mechanism further includes a worm gear and a worm. The worm gear is coaxially fixed to the end of the transmission rod away from the passive disk, and the worm is fixed at the center of the first cam and meshes with the worm gear.

[0015] By adopting the above technical solution, the first cam is used to drive the worm to rotate synchronously, and at the same time drive the worm gear to engage and move together, and the transmission rod is driven to rotate synchronously by the worm gear.

[0016] Optionally, a synchronizing plate is arranged between the Y-axis pushing rod and the driven plate, and the synchronizing plate is rotatably connected to both of them.

[0017] By adopting the above technical solution, when the driven plate rotates, the synchronizing plate is used to drive the Y-axis pushing rod to slide synchronously on the support plate.

[0018] Optionally, the X-axis pushing mechanism further includes a limiting cylinder and a reset rod. One end of the reset rod is slidably clamped in the limiting cylinder, and an elastic resetting member is arranged at the connection between the two. The other end of the limiting cylinder is rotatably connected to the end of the linkage plate away from the clamping seat, and the other end of the reset rod is rotatably connected to the support plate.

[0019] By adopting the above technical solution, the sliding of the reset rod in the limiting cylinder and the elastic force of the elastic resetting member are used to push the linkage plate to rotate, so that the contact wheel can be in close contact with the first cam.

[0020] Optionally, at least two guide rods are arranged in parallel.

[0021] By adopting the above technical solution, the limiting effect is achieved by arranging multiple guide rods, avoiding the deflection of the docking seat caused by the rotation of a single guide rod.

[0022] Optionally, a rubber pad is arranged at the abutting end of the X-axis pushing plate and the forging.

[0023] By adopting the above technical solution, the rubber pad is used to avoid abrasion on the surface of the forging.

[0024] Optionally, a rolling wheel is rotatably connected to one end of the linkage plate, and the rolling wheel is clamped in the card seat.

[0025] By adopting the above technical solution, the rolling of the rolling wheel reduces the abrasion of the linkage plate in the card seat.

By using the cam mechanisms in the X-axis pushing mechanism and the Y-axis pushing mechanism to drive the linkage of the X-axis and Y-axis push rods, replacing the split cylinder structure, and realizing the sequential connection of the actions of the two axes through mechanical phase difference control, the synchronous error of the forging pushing and positioning is reduced, significantly superior to the traditional pneumatic system, and the multi-directional driving effect of a single power source is achieved; 2. Using the mechanical timing control of the cam-linkage mechanism to replace the PLC programming logic, eliminating the serial delay of the double-cylinder actions, shortening the single loading cycle, effectively improving the production line rhythm, greatly reducing the dependence on electricity control, and at the same time intensifying the energy consumption. For example, the linkage mechanism uses a single driving device to make the X-axis pushing plate and the Y-axis pushing rod achieve two-axis movement, which is more energy-saving than the double-cylinder independent air path system, and avoids the problem of movement misalignment caused by air pressure fluctuations, fundamentally solving the technical bottlenecks of the double-cylinder system in terms of timing synchronization, space occupation and energy consumption efficiency, and providing a better automatic loading solution for the large-scale production of high-precision forgings for vehicle axles.

There is a support plate 4 on one side of the forging guiding groove 2, and the support plate 4 is fixed on an external support structure. Both the X-axis pushing mechanism 5 and the Y-axis pushing mechanism 6 are arranged on the support plate 4. By using the cam mechanism in the X-axis pushing mechanism 5 and the Y-axis pushing mechanism 6 to drive the linkage of the X-axis and Y-axis push rods, replacing the split cylinder structure, the timing connection of the actions of the two axes is realized through mechanical phase difference control, reducing the synchronous error of the pushing and positioning of the forging 3, significantly superior to the traditional pneumatic system. It realizes the multi-directional driving effect with a single power source. At the same time, the mechanical timing control of the cam-linkage mechanism replaces the PLC programming logic, eliminating the serial delay of the double-cylinder actions, shortening the single feeding cycle, effectively improving the production line beat, greatly reducing the dependence on electricity control, and at the same time intensifying the energy consumption. For example, the linkage mechanism enables the X-axis pushing plate 53 and the Y-axis pushing rod 64 to achieve the movement of the two axes through a single driving device, which is more energy-efficient than the double-cylinder independent air circuit system and avoids the problem of movement misalignment caused by air pressure fluctuations. Fundamentally, it solves the technical bottlenecks of the double-cylinder system in terms of timing synchronization, space occupation and energy consumption efficiency, providing a better automatic feeding solution for the large-scale production of high-precision forgings of vehicle axle heads.

[0038] In the embodiment of the present application, the first fixed plate 61 and the second fixed plate 62 are both fixed on one side of the support plate 4, the driven plate 63 is rotatably connected to the second fixed plate 62, the Y-axis push rod 64 of the 匚-shaped structure is slidably clamped on the support plate 4 along the Y-axis direction, and one end of the Y-axis push rod 64 is rotatably connected to the driven plate 63, and the other end is located on one side of the forging guide groove 2, the transmission rod 67 is rotatably connected to the first fixed plate 61, the passive disk 65 is coaxially fixed on one end of the transmission rod 67, the cam groove 66 is concavely arranged on the passive disk 65, and a protrusion is arranged on the end of the driven plate 63 away from the Y-axis push rod 64, and the protrusion is slidably clamped in the cam groove 66.

The first cam 56 is used to drive the worm 69 to rotate synchronously, and at the same time drives the worm wheel 68 to engage and link, and drives the transmission rod 67 to rotate synchronously through the worm wheel 68.

[0040] The worm wheel 68 is coaxially fixed to an end of the transmission rod 67 away from the passive disk 65 . The worm 69 is fixed at the axis of the first cam 56 and meshes with the worm wheel 68 .

[0041] In the embodiment of the present application, a synchronization plate is arranged between the Y-axis push rod 64 and the driven plate 63, and the synchronization plate is rotationally connected to both of them. The synchronization plate is used to enable the driven plate 63 to drive the Y-axis push rod 64 to slide synchronously on the support plate 4 when it rotates.

[0042] The X-axis driving mechanism 5 also includes a limiting cylinder 58 and a reset rod 59 . The reset rod 59 slides in the limiting cylinder 58 and the elastic force of the elastic reset member pushes the linkage plate 54 to rotate, so that the abutment wheel 57 can be tightly abutted against the first cam 56 .

The rubber pad is used to avoid abrasion on the surface of the forging 3, and at the same time, the rolling of the rolling wheel reduces the abrasion of the linkage plate 54 in the clamping seat 55.

[0046] The implementation principle of a feeding device for a vehicle axle head forging in the embodiment of the present application is as follows: First, connect the first cam 56 with an external driving device. Drive the first cam 56 to rotate through the external driving device. When the first cam 56 rotates, the abutting wheel 57 is linked at its edge and drives the linkage plate 54 to rotate. At this time, the linkage plate 54 drives the clamping seat 55 to be linked, and then the docking seat 52 drives the X-axis pushing plate 53 to move in a fixed direction under the limiting action of the guide rod 51, and pushes the forging 3 located on the forging conveyor belt 1 into the forging guide groove 2. At the same time, the first cam 56 drives the worm 69 to rotate synchronously, and at the same time drives the worm gear 68 to be meshed and linked, and drives the transmission rod 67 to rotate synchronously through the worm gear 68. At this time, the passive disk 65 rotates so that the convex block at one end of the driven plate 63 slides in the cam groove 66, and drives the driven plate 63 to rotate through the limiting action of the cam groove 66.
