Description

Technical Field

[0001] The invention relates to the technical field of air spring vulcanizers, in particular to an automatic shaping air spring vulcanizer. Background Art

[0002] The air spring vulcanizer is a key equipment used for vulcanizing air springs. It vulcanizes rubber through high temperature and high pressure to ensure the formation of a stable cross-linked structure between rubber molecules, thereby improving the elasticity, wear resistance and corrosion resistance of the rubber.

[0003] According to an automated shaping air spring vulcanizer disclosed (publication number: CN211640673U), the above application adopts PLC automatic control module control, controls the movement of the vulcanization mold assembly through the side slide plate, and the closing and opening of the chuck, mold demolding and mold loading are all automatically operated. The descent and ascent of the center rod, and the filling and release of the inner bag are all automatically and accurately controlled, which improves the demolding and mold loading efficiency, reduces the labor intensity of workers, saves operation time, improves production efficiency, and effectively guarantees the product qualification rate.

[0004] In the above patent, the vulcanization operation is performed by moving the upper mold downward to cooperate with the lower mold, and then starting the heating plate. Because the heating temperature of the heating plate is too high, the outer walls of the upper mold and the lower mold will also heat up, and as a result, during the vulcanization process, the workers may accidentally touch the outer walls of the upper mold and the lower mold, which may easily cause burns. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an automatic shaping air spring vulcanizer, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automated shaping air spring vulcanizer, comprising a frame base, a support rod is fixed on the top of the frame base, a top plate is fixed on the top of the support rod, a cylinder is fixed on the top of the top plate, a movable plate is fixed on the bottom output end of the cylinder, an upper mold is fixed on the bottom of the movable plate, an upper heating plate is fixed on the inner side of the upper mold, a lower mold is fixed on the top of the frame base, and a lower heating plate is fixed on the inner side of the lower mold, by starting the cylinder, the output end of the cylinder drives the movable plate to move downward, drives the upper mold to move downward, and covers the air spring raw material through the upper mold and the lower mold to perform vulcanization operation, a protective component is provided on the frame base, and a positioning component and an extrusion component for clamping the air spring raw material are also provided; wherein the protective component comprises a disc, an extrusion rod, a transmission rod, a connecting block, a reset spring, an L-shaped connecting plate, a sliding rod, an inclined block, a movable ring, a hinge seat, a protective cover, a push rod and a demoulding disc, the disc is fixed on the upper The outer wall of the mold, the bottom of the disc is fixed with an extrusion rod, the frame base is penetrated by a transmission rod, and the transmission rod is slidably connected with the penetration of the frame base, and a moving ring is fixed on the top of the transmission rod, and the inner wall of the moving ring is in contact with the outer wall of the lower mold. When the upper mold moves upward, it can drive the disc to move downward, so that the extrusion rod squeezes the moving ring, so that the moving ring can drive the transmission rod to move downward, and a hinge seat is fixed on the top of the frame base, and a protective cover is hinged on the hinge seat. The protective cover is provided with two groups, and the two groups of protective covers are symmetrically arranged with the center line in the vertical direction of the frame base as the symmetry axis, and an L-shaped connecting plate is fixed on the outer wall of the moving ring, and a sliding rod is fixed on the inner side of the L-shaped connecting plate, and an inclined block is fixed on the inner side of the protective cover, and the sliding rod penetrates the through hole in the middle of the inclined block. When the moving ring moves downward, the sliding rod will squeeze the inclined block at the through hole of the inclined block, so that the inclined block can rotate, thereby driving the protective cover to rotate, and covering the upper and lower molds during processing for protection.

[0007] According to the above technical solution, a connecting block is fixed to the bottom of the transmission rod, a return spring is fixed to the top of the connecting block, and the top of the return spring is fixed to the bottom of the frame base.

[0008] According to the above technical solution, a push rod is fixed on the top of the connecting block, and a demolding plate is fixed on the top of the push rod. When the upper mold drives the extrusion rod to move upward, the extrusion rod will not squeeze the movable ring. The reset spring is in a stretched state, driving the connecting block and the push rod to move upward, so that the demolding plate can drive the air spring to move out of the lower mold.

[0009] According to the above technical scheme, the positioning assembly includes a slide plate, a push rod, a slide groove, an L-shaped connecting sleeve, a sleeve rod, a connecting spring, an arc plate and a ball bearing.

When the transmission rod moves downward, the push rod moves in the slide groove, so that the push rod can squeeze the inclined groove end in the slide groove, which will cause the slide plate to be forced to move closer to the lower mold.

[0010] According to the above technical solution, a connecting spring is fixed at one end of the sleeve rod, and an arc-shaped plate is fixed at the other end of the sleeve rod. A ball rolls on the inner side of the arc-shaped plate. The end of the connecting spring away from the sleeve rod is fixed to the inner wall of the L-shaped connecting sleeve. When the slide plate approaches the lower mold, the sleeve rod is driven to move through the L-shaped connecting sleeve, and the arc-shaped plate drives the ball to move, so as to center the air spring raw material.

[0011] According to the above technical solution, the extrusion assembly includes a rotating rod, a fixed sleeve, a spring, an extrusion rod, a connecting tube, a transmission spring, a limit rod, a hinge rod and a limit hole.

[0013] According to the above technical solution, a limiting rod is slidably installed on the inner wall of the connecting tube, the limiting rod passes through the top of the arc plate, a limiting hole is opened on the extrusion rod, the inner wall of the limiting hole is in contact with the outer wall of the limiting rod, a transmission spring is fixed to the bottom of the limiting rod, the bottom of the transmission spring is fixed to the inner wall of the connecting tube, and through the cooperation of the limiting hole and the limiting rod, the extrusion rod can be limited.

[0014] The present invention provides an automatic shaping air spring vulcanizing machine. It has the following beneficial effects:

[0015] (1) In the automatic shaping air spring vulcanizer, when the upper mold moves downward for vulcanization, the extrusion rod and the moving ring cooperate to make the L-shaped connecting plate drive the sliding rod to move downward, which will squeeze the through hole of the inclined block, so that the inclined block rotates toward the lower mold, thereby making the protective cover rotate at the hinge, so that the two sets of protective covers will shield and protect the upper mold and the lower mold during vulcanization, avoiding workers from touching the upper mold or the lower mold and causing burns. After vulcanization, when the upper mold moves upward away from the moving ring, the moving ring is not squeezed. Through the cooperation of the reset spring, the connecting block drives the ejector rod and the demoulding plate to move upward, so that the demoulding plate can drive the vulcanized material to move out, which is convenient for demoulding.

[0016] (2) In the automatic shaping air spring vulcanizer, when the moving ring moves downward, it drives the transmission rod to move downward, causing the push rod to move in the slide groove of the slide plate, so that the push rod squeezes the slide plate to move toward the lower mold. The ball bearings on the arc plate can be used to center the demoulding plate, so that the raw material is in the middle of the lower mold and the upper mold, so that the raw material is heated evenly during vulcanization. In addition, by setting up multiple groups of ball bearings, the air spring raw material can move back and forth smoothly in the lower mold, preventing the arc plate from directly contacting the air spring, which causes large friction and makes it inconvenient for the air spring to move in the lower mold.

[0017] (3) The automatic shaping air spring vulcanizer, when encountering deformed air spring raw materials, uses the ball bearing to center the air spring raw materials, which causes the steel ball to be squeezed, causing the sleeve rod to move into the L-shaped connecting sleeve. Through the cooperation of the hinged rod and the connecting tube, the limit rod is moved out of the limit hole, releasing the limit on the extrusion rod, and causing the extrusion rod to rotate toward the demolding disk, so that the air spring raw materials can be knocked down from the demolding disk and moved outward, and the air spring raw materials can be pushed out of the lower mold. The deformed air spring raw materials are not processed, and deformation of the raw materials is prevented. If the air spring raw materials are processed, the produced materials will be unqualified and scrapped, resulting in a waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] By rotating the two sets of protective covers 17 close to each other, when the air spring is vulcanized, the protective covers 17 can cover the upper mold 6 and the lower mold 7, thereby playing a protective role and preventing the staff from accidentally touching the high-temperature upper mold 6 or lower mold 7 and causing burns.

[0031] A slot is provided on the frame base 1 at the bottom of the inclined block 20 to prevent the inclined block 20 from being blocked by the frame base 1 when rotating.

[0032] A push rod 22 is fixed on the top of the connecting block 21. The push rod 22 passes through the bottom of the lower mold 7 and the frame base 1, and is slidably connected at the penetration point. A demolding plate 23 is fixed on the top of the push rod 22. Through the setting of the demolding plate 23, when the vulcanization of the air spring is completed, the demolding operation of the air spring can be facilitated through the demolding plate 23.

[0033] When this embodiment is working: when it is necessary to perform vulcanization operation on the air spring, the raw material of the air spring is placed on the demoulding plate 23. After it is placed, the cylinder 4 is started so that the output end of the cylinder 4 can drive the movable plate 5 to move downward, so that the upper mold 6 is close to the lower mold 7 to perform the vulcanization operation. When the upper mold 6 moves downward, the disc 11 and the extrusion rod 12 also move downward at the same time. When the disc 11 drives the extrusion rod 12 to move downward to contact with the moving ring 14, when the disc 11 drives the extrusion rod 12 to continue to move downward, the moving ring 14 drives the transmission rod 13 to move downward, so that the connecting block 21 drives the ejector rod 22 and the demoulding plate 23 to move downward, and when the connecting block 21 moves downward, the reset spring 15 is stretched, so that the demoulding plate 23 drives the air spring 21 to move downward. The gas spring raw material enters the lower mold 7, and when the movable ring 14 moves downward, the L-shaped connecting plate 18 will drive the slide rod 19 to move downward, and the slide rod 19 will move in the through hole of the inclined block 20, so that the slide rod 19 will squeeze the inclined block 20, and the inclined block 20 will rotate toward the lower mold 7, and the inclined block 20 will drive the protective cover 17 to rotate toward the lower mold 7. When the bottom of the upper mold 6 fits with the top of the lower mold 7, the two sets of protective covers 17 will cover the lower mold 6 and the upper mold 7, and then the upper heating plate 8 and the lower heating plate 9 can be started, and the vulcanization operation is carried out by heating. The protection of the protective cover 17 ensures the safety of the staff, and prevents the staff from accidentally touching the upper mold 6 and the lower mold 7 when the equipment is working, thereby preventing burns.

[0034] When vulcanization is completed, when the output end of the cylinder 4 drives the movable plate 5 to move upward, the upper mold 6 will be away from the lower mold 7, so that the extrusion rod 12 will not squeeze the movable ring 14. Because the reset spring 15 is in a stretched state, the reset spring 15 will drive the connecting block 21 to move upward, so that the push rod 22 can drive the demoulding plate 23 to move upward, so that the demoulding plate 23 can demould the vulcanized air spring from the lower mold 7, which is convenient for the staff to take the material. When the connecting block 21 moves upward, the L-shaped connecting plate 18 will drive the slide bar 19 to move upward, so that the slide bar 19 squeezes the inclined block 20 for rotational reset, and the two sets of protective covers 17 are rotated and unfolded to expose the vulcanized air spring for material taking and discharge operations.

[0035] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, a positioning assembly and an extrusion assembly for clamping the air spring raw material are further provided on the frame base 1, and the positioning assembly includes a slide plate 241, a slide groove 243, a push rod 242, an L-shaped connecting sleeve 244, a connecting spring 248, a sleeve rod 245, an arc plate 246 and a ball 247; the slide plate 241 is slidably mounted on the top of the frame base 1, and a slide groove 243 is provided on the slide plate 241, and the slide groove 243 is divided into an oblique groove and a straight groove, and the upper part is an oblique groove, and the lower part is a straight groove, and the transmission rod 1 A push rod 242 is fixed to the outer wall of 3, and the push rod 242 passes through the slide groove 243, and the penetration is in close contact. An L-shaped connecting sleeve 244 is fixed to the top of the slide plate 241, and a sleeve rod 245 is slidably installed on the inner wall of the L-shaped connecting sleeve 244. A connecting spring 248 is fixed to one end of the sleeve rod 245, and an arc plate 246 is fixed to the other end of the sleeve rod 245. The end of the connecting spring 248 away from the sleeve rod 245 is fixed to the inner wall of the L-shaped connecting sleeve 244, and the sleeve rod 245 passes through the lower mold 7, and the penetration is in close contact. A plurality of groups of balls 247 roll on the inner side of the arc plate 246.

[0036] There are two groups of arc plates 246, and the two groups of arc plates 246 are symmetrically arranged with the center line of the lower mold 7 in the vertical direction as the symmetry axis. When the demolding plate 23 moves downward, the arc plates 246 will be aligned with the air spring raw material on the demolding plate 23. By arranging the arc plates 246 to drive the balls 247 to approach each other, the air spring raw material can be squeezed and centered, so that the air spring is in the middle position, which ensures that the air spring raw material is heated more evenly during processing, thereby improving product quality.

[0037] When the ball 247 is centered with the air spring material, and because the demolding plate 23 will drive the air spring to move up and down, multiple groups of balls 247 are arranged on the arc plate 246 to ensure that the air spring moves smoothly when it moves up and down, and prevent the arc plate 246 from directly contacting the air spring with large friction, making it inconvenient for the air spring to move in the lower mold 7.

[0038] The extrusion assembly also includes a fixed rod 255, a connecting tube 256, a limiting rod 258, a limiting hole 260, a rotating rod 251, a fixed sleeve 252, a spring 254, an extrusion rod 253, a hinge rod 259 and a transmission spring 257; the fixed rod 255 is fixed to the inner wall of the L-shaped connecting sleeve 244, the bottom of the arc plate 246 is penetrated by the connecting tube 256, and the penetration is slidably connected, the inner wall of the connecting tube 256 is slidably installed with a limiting rod 258, the limiting rod 258 penetrates the top of the arc plate 246, and the penetration is slidably connected, the bottom of the limiting rod 258 is fixed with a transmission spring 257, and the bottom of the transmission spring 257 is fixed to the connecting tube The inner wall of the arc plate 246 is fixed with a fixing sleeve 252, the top of the arc plate 246 is rotatably installed with a rotating rod 251, the top of the rotating rod 251 is fixed with an extrusion rod 253, the outer wall of the rotating rod 251 is fixed with a spring 254, the side of the spring 254 away from the rotating rod 251 is fixed to the inner wall of the fixing sleeve 252, the extrusion rod 253 is provided with a limiting hole 260, the inner wall of the limiting hole 260 is fitted with the outer wall of the limiting rod 258, the end of the fixing rod 255 away from the L-shaped connecting sleeve 244 is hinged with a hinged rod 259, and the end of the hinged rod 259 away from the fixing rod 255 is hinged to the outer wall of the connecting tube 256.

[0039] Two groups of extrusion rods 253 are provided, and the two groups of extrusion rods 253 are symmetrically arranged with the center line of the lower mold 7 in the vertical direction as the symmetry axis. The deformed air spring material can be extruded and pushed out through the extrusion rods 253.

[0040] The mainspring 254 is originally in a contracted state. By releasing the limit on the extrusion rod 253 , the mainspring 254 drives the rotating rod 251 to rotate.

[0041] When the present embodiment is working, when the extrusion rod 12 squeezes the moving ring 14 to move downward, the transmission rod 13 drives the push rod 242 to move downward, so that the push rod 242 moves in the slide groove 243 of the slide plate 241. When the push rod 242 moves in the inclined groove section of the slide groove 243, the push rod 242 squeezes the inclined groove of the slide groove 243, and the slide plate 241 is moved to the lower mold 7 by the extrusion force, thereby driving the L-shaped connecting sleeve 244 to move, and driving the sleeve rod 245 to move through the connecting spring 248, so that the two groups of arc plates 246 are close to each other, and the ball 247 in the arc plate 246 can be centered on the air spring material placed on the demoulding plate 23, so that the ball 247 just fits with the air spring material, so that the air spring material is in the middle position between the lower mold 7 and the upper mold 6, so that when the air spring is pressed During the vulcanization operation, the air spring raw material is heated evenly, so that the product quality is better, and when the push rod 242 moves to the straight groove of the slide groove 243, the push rod 242 will not squeeze the slide plate 241, so that the ball 247 will center the air spring raw material, so that the upper mold 6 can continue to move downward for vulcanization operation, and when the extrusion rod 12 moves upward and does not squeeze the movable ring 14, the reset spring 15 will drive the connecting block 21 and the transmission rod 13 to move upward, so that the transmission rod 13 makes the push rod 242 move in the slide groove 243 of the slide plate 241, and when the push rod 242 moves to the oblique groove section of the slide groove 243, the push rod 242 will squeeze the slide plate 241 away from the lower mold 7, so that the L-shaped connecting sleeve 244 drives the sleeve rod 245 to move out of the lower mold 7, and the arc plate 246 drives the ball 247 back to its original position, and the next centering operation can be carried out.

[0042] When the air spring is deformed, when the arc plate 246 drives the ball 247 to center the air spring, the deformation of the air spring material will cause the ball 247 to not fit with the air spring, and the ball 247 will be squeezed, so that the arc plate 246 drives the sleeve rod 245 to move toward the L-shaped connecting sleeve 244, so that the fixed rod 255 will squeeze the hinge rod 259, so that the hinge rod 259 rotates at the hinge, so that the hinge rod 259 squeezes the connecting tube 256 to move downward, thereby transmitting the spring 257. The limiting rod 258 can be driven to move out of the limiting hole 260 to release the limiting of the extrusion rod 253. Since the clockwork spring 254 is in a contracted state, the extrusion rod 253 can be rotated, and the extrusion rod 253 can be rotated toward the demoulding plate 23, so that the extrusion rod 253 can hit the air spring raw material on the demoulding plate 23, and the air spring raw material can be knocked down from the demoulding plate 23 and moved outward, and the air spring raw material can be pushed out from the lower mold 7, and the deformed air spring raw material is not processed, so as to prevent the deformation of the raw material and the air spring raw material. The material is processed, which will result in the production of unqualified materials to be scrapped, resulting in a waste of resources. In addition, when the extrusion rod 253 needs to be returned, the sleeve rod 245 moves into the L-shaped connecting sleeve 244, which will cause the connecting spring 248 to be deformed. When the arc plate 246 is not squeezed, the reaction force of the connecting spring 248 will cause the sleeve rod 245 to reset, drive the arc plate 246 to return, and pull the hinged rod 259, so that the connecting tube 256 drives the limit rod 258 to reset. A protrusion is fixed. When the extrusion rod 253 needs to be returned, the protrusion can be pressed downward to move the limit rod 258 into the connecting tube 256 to compress the transmission spring 257. By rotating the extrusion rod 253, when the extrusion rod 253 is rotated until the limit hole 260 is aligned with the limit rod 258, the protrusion on the limit rod 258 is released. Since the transmission spring 257 is in a compressed state, the limit rod 258 extends into the limit hole 260, fixes the extrusion rod 253, and resets the extrusion rod 253 for the next operation.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
