In the embodiment, the method for processing the saw chain guide plate roller is to manufacture a cylindrical roller prefabricated product by extruding and molding a spherical blank, and then heat-treat the roller prefabricated product to obtain the finished cylindrical roller.

It should be noted that the spherical blank can be made from standard-size steel balls purchased in the market through annealing treatment, and the size of the formed roller is ensured by the size precision of the spherical blank by utilizing the principle that the volume of the extruded material is unchanged after the extruded material is deformed.

The embodiment provides extrusion equipment of roller, and this equipment includes frame, feed mechanism, forming mechanism, discharge mechanism.

As shown in fig. 3, the housing includes a base 100, a top plate 200, and a plurality of housing uprights 300. The base 100 and the top plate 200 are connected by a frame upright 300, and a processing area is formed between the base 100 and the top plate 200, so as to be provided with a feeding mechanism with a feeding channel 20, a forming mechanism for extrusion forming of the spherical blank N, a discharging mechanism with a discharging channel 40 and the like.

Wherein, forming mechanism includes die carrier 1 and lower die carrier 2. Lower die carrier 2 sets up in base 100 top through frame stand 300 frame is built on stilts, goes up die carrier 1 and sets up between lower die carrier 2 and roof 200, is equipped with direction bearing structure between lower die carrier 2 and the roof 200, and direction bearing structure includes vertical guide pillar 700, goes up die carrier 1 and can be for lower die carrier 2 up-and-down motion along vertical guide pillar 700, and direction bearing structure is in order to play the direction supporting role in last module assembly 502 up-and-down motion process.

As shown in fig. 3, the molding mechanism of the present embodiment further includes a lower die assembly 501, an upper die assembly 502 mated with the lower die assembly 501, a first drive mechanism 503, and a second drive mechanism 504. The first drive mechanism 503 drives the upper die assembly 502 to move up and down, and the second drive mechanism 504 drives the lower die assembly 501 to move horizontally.

As shown in fig. 3 to 6, in particular, the lower mold assembly 501 is movably provided on the lower mold frame 2, and the upper surface of the lower mold assembly 501 is provided with at least one molding groove 5 having a cylindrical cavity. The upper die component 502 is fixedly arranged below the upper die frame 1, and the lower surface of the upper die component 502 is provided with a forming male die 3 and a shaping male die 4 which are matched with the forming groove 5. The forming convex die 3 and the shaping convex die 4 are arranged in parallel along the movement direction of the forming groove 5, so that the forming groove 5 can be matched with the forming convex die 3 and the shaping convex die 4 in sequence.

Thus, the upper die assembly 502 moves downward, and the forming male die 3 is matched with the forming groove 5 to extrude the spherical blank N placed in the forming groove 5 into a cylindrical blank; the shaping punch 4 cooperates with the shaping groove 5 for press shaping the upper end face of the cylindrical blank to form the roller preform M.

In the actual machining process, the second driving mechanism 504 drives the lower die assembly 501 to move the forming groove 5 from the feeding end S1 on the side of the feeding passage 20 to the discharging end S2 on the side of the discharging passage 40 through the machining positions S3 of the forming punch 3 and the shaping punch 4.

The feed mechanism delivers the spherical blanks N and places them one by one through the feed channel 20 into the forming flute 5 at the feed end S1. Thereafter, the second driving mechanism 504 drives the lower die assembly 501 to move the forming groove 5 containing the spherical blank N below the forming punch 3, and then the first driving mechanism 503 drives the upper die frame 1 to move downward, the forming punch 3 gradually presses the spherical blank N, and finally the spherical blank N is pressed into a cylindrical blank. Then, the first driving mechanism 503 drives the upper mold frame 1 to move upward, and the second driving mechanism 504 drives the lower mold assembly 501 to move continuously in the moving direction, so that the forming groove 5 containing the cylindrical blank moves below the shaping punch 4. Then, the first driving mechanism 503 drives the upper die carrier 1 to move downward, and the shaping male die 4 performs extrusion shaping on the upper end surface of the cylindrical blank to form the roller preform M. Finally, the first driving mechanism 503 drives the upper mold frame 1 to move upward, and the second driving mechanism 504 drives the lower mold assembly 501 to move the molding groove 5 containing the roller preform M to the discharge passage 40 side of the discharge mechanism, and to be discharged from the apparatus through the discharge passage 40.

It should be noted that the addition of the shaping step after the extrusion step allows the resulting roller preform M to be more precise in size and flatter.

And in the process of being changed into a cylinder by the extrusion of the ball body, the arc chamfer angle is naturally formed between the cylindrical surface and the two end surfaces, so that the remaining space of the lubricating oil can be effectively increased, the lubricating effect is enhanced, and the frictional resistance is reduced.

It should be noted that, during the process of driving the upper die assembly 502 to move downwards, when the shaping punch 3 or the shaping punch 4 contacts the workpiece to be pressed, the speed of the first driving mechanism 503 is gradually reduced, so as to avoid excessive deformation caused by excessive punching force.

In this embodiment, the first driving mechanism 503 provides the forming power, and the first driving mechanism 503 is a motor with a crankshaft structure, so that the existing punching machine can be used. Because the saw chain guide plate roller is small in size and the diameter of the saw chain guide plate roller is generally not more than 4.5mm, the extrusion force required by forming can be met by a 25-ton punching machine during forming.

In a specific embodiment, the second driving mechanism 504 includes a longitudinal central shaft, the lower mold assembly 501 is horizontally disposed perpendicular to the longitudinal central shaft, and the lower mold assembly 501 rotates in a plane of 360 degrees around the longitudinal central shaft, thereby moving the forming groove 5. The 360-degree rotation mode can enable the forming groove 5 to rotate to the position below the forming male die 3 again to achieve continuous processing.

More preferably, the upper surface of the lower die assembly 501 is provided with a plurality of molding grooves 5 in a circle around the center of rotation. From 8 to 24 forming recesses 5 may be provided in the lower die assembly 501 depending on the product and the actual situation. Every time the upper die assembly 502 moves downwards, the lower die assembly 501 rotates by a division angle, so that the forming groove 5 is aligned with the forming male die 3 and the shaping male die 4, and next extrusion is carried out, thereby realizing continuous production. Therefore, the production efficiency is further improved, the preparation period is shortened, the production speed is high, and the production cost is reduced.

As shown in fig. 5-6, the lower mold assembly 501 includes a forming plate 6 and a forming ejector rod 7, the forming plate 6 is provided with a forming through hole 8, the forming ejector rod 7 penetrates into the forming through hole 8 from the lower part of the forming plate 6, and the upper end surface of the forming ejector rod 7 and the inner wall of the forming through hole 8 are enclosed to form a forming groove 5.

Further, the lower die assembly 501 further comprises a mounting disc 9 arranged below the forming disc 6, the mounting disc 9 surrounds the longitudinal central axis and is tightly attached to the lower surface of the forming disc 6, and the mounting disc 9 is fixedly connected with the forming disc 6 to rotate synchronously. The mounting plate 9 is provided with a mounting hole 10 opposite to the molding through hole 8, and the lower section of the molding ejector rod 7 is accommodated in the mounting hole 10.

The fixed platen 12 is fixed to the lower mold frame 2 and does not move with the lower mold assembly 501.

The transition disc 11 is provided with a guide through hole 14 corresponding to the forming ejector rod 7, and the discharging ejector rod 13 is accommodated in the guide through hole 14. The discharging ejector rod 13 can move upwards and act on the lower end surface of the forming ejector rod 7; the downward movement acts on the upper surface of the stationary platen 12.

As shown in fig. 5-8, the upper surface of the fixed tray 12 is provided with an ejection slide way 15 matched with the discharge ejector rod 13. The ejection slide way 15 has a slope, the lowest position of the ejection slide way is located at the feeding end S1, the highest position of the ejection slide way is located at the discharging end S2, and the discharging ejector rod 13 moves up and down along the ejection slide way 15 due to the change of the slope, so that the forming ejector rod 7 is driven to move up and down. Thus, when the transition plate 11 moves the discharge ejector pin 13 along the ejection slide 15 from the feeding end S1 to the discharging end S2, the roller preform M in the molding groove 5 at the discharging end S2 is ejected from the molding through hole 8 and enters the discharge passage 40.

The ejection slide way 15 is an annular slide way 15, the lowest position is located at the feeding end S1, and the highest position is located at the discharging end S2, and corresponds to the forming groove 5 which is formed in an annular shape. The feeding end S1 and the discharging end S2 are in smooth transition through a slope.

As shown in fig. 5 and 9, a limiting structure is preferably arranged between the forming ram 7 and the mounting hole 10 to limit the forming ram 7 to be separated from the mounting plate 9. In the present embodiment, the diameter of the mounting hole 10 is larger than the forming through-hole 8 and the guide through-hole 14. The forming ejector rod 7 is formed by connecting two sections of cylinders in a stepped manner, the diameter of the upper section cylinder 71 is slightly smaller than that of the forming through hole 8, and the diameter of the lower section cylinder 72 is equal to that of the mounting hole 10, so that the lower section cylinder 72 of the forming ejector rod 7 cannot enter the guide through hole 14, and the forming ejector rod 7 is limited to be separated from the mounting disc 9.

And the diameter of the upper end surface of the discharging ejector rod 13 is obviously smaller than that of the lower end surface of the forming ejector rod 7 due to the arrangement, so that the discharging ejector rod 13 can act on the forming ejector rod 7 more stably, and the phenomenon that the discharging ejector rod 13 is inclined to cause jamming is avoided.

Preferably, as shown in fig. 6, the forming disc 6, the fixed disc 12, the mounting disc 9 and the transition disc 11 are circular discs, so that the device is more compact.

The second drive mechanism 504 and the roundness divider are provided on the base 100. The longitudinal central shaft passes through the fixed disc 12 and the lower die frame 2 to be connected with the roundness divider. The roundness divider rotates lower die assembly 501 one index angle at a time.

In addition, the feeding mechanism of this embodiment is an automatic feeding mechanism, and the feeding inlet of the feeding channel 20 is fixed at the feeding end S1 through a bracket, so that the feeding inlet is aligned with the forming groove 5 at the feeding pause. In the pause period of each forming, the vibrating disc of the feeding mechanism moves, the forming groove 5 of the automatic feeding end S1 falls into a spherical blank N, the spherical blank N rotates along with the lower die assembly 501 to be formed, and finally the spherical blank N enters the discharging channel 40 from the discharging end S2 and slides to the material receiving container to finish discharging.

Further preferably, as shown in fig. 3 and 4, the upper surface of the lower die assembly 501 at the discharge end S2 is provided with a discharge baffle 16, and the discharge baffle 16 guides the machined roller into the discharge channel 40.
