2, cylinder lifting rubber-spring complex vibration isolation form, the plain bumper of this form is the lifting of leaning on the inflation of cylinder and exhaust to ensure roller bed frame, and jolt ramming frame itself remains unchanged, the exciting force of vibrating motor the most easily passes to Equipment Foundations, cause peripheral equipment to vibrate together with building, affect surrounding resident life.
3, cylinder lifting polyurethane rubber slab vibration isolation form, the plain bumper of this form is the lifting of leaning on the inflation of cylinder and exhaust to ensure roller bed frame, same jolt ramming frame itself remains unchanged, the exciting force of vibrating motor the most easily passes to Equipment Foundations too, and Amplitude Comparison is little, be not easy adjustment.Peripheral equipment can be caused equally to vibrate together with building, affect surrounding resident life.
Summary of the invention
The purpose of this utility model is for the problems referred to above, a kind of casting and molding plain bumper is provided, jolt ramming pallet face maintenance level when this plain bumper can make plain bumper work, ensure that molding sand jolt ramming is even, when plain bumper can be made again to work, the exciting force of vibrating motor is delivered to Equipment Foundations after significantly reducing.
The technical scheme realizing above-mentioned purpose is: a kind of casting and molding plain bumper, include the roller bed frame be fixed in Equipment Foundations, laterally be arranged in the carrying roller above this roller bed frame and carrying roller driving mechanism, jolt ramming frame is provided with in described roller bed frame, the bottom of this jolt ramming frame arranges vibrating motor, the upper end of this jolt ramming frame is provided with the joist be horizontally arranged between described carrying roller, the spring assembling stand protruding from these jolt ramming frame left and right sides is furnished with in the lower part of described jolt ramming frame, the perpendicular rubber air spring put is respectively equipped with below each spring assembling stand, the perpendicular rubber spring put is respectively equipped with on each spring assembling stand, each rubber air spring and form a spring assembly with a rubber spring of its configuration, arrange one in the side of each spring assembly and be fixed on jolt ramming stand in Equipment Foundations, the lower end of the rubber air spring that each jolt ramming stand is corresponding is fixed on above the base body of this jolt ramming stand lower end, the upper end of the rubber spring that each jolt ramming stand is corresponding coordinates with below the upper pedestal of this jolt ramming stand upper end.
Further, the described spring assembly be made up of a rubber air spring and a rubber spring arranges three groups respectively the left and right sides of described jolt ramming frame is uniform.
Further, the rubber air spring of described spring assembly and rubber spring coaxial line are arranged.
The level of swing table surface when the utility model can keep work, make molding sand jolt ramming even, compact rate of molding is high, and surface quality is good, reduces equipment failure rate simultaneously, improves production safety ability, ensures the normal operation of producing.Impact on factory building foundation when particularly significantly can reduce equipment noise during plain bumper work and significantly reduce vibration.
Accompanying drawing explanation
Fig. 1 is the front view of this casting and molding plain bumper.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
By reference to the accompanying drawings detailed description of the invention of the present utility model is described.
As shown in Figure 1, Figure 2, this casting and molding plain bumper, includes roller bed frame 1, and this roller bed frame 1 is fixed in Equipment Foundations.Horizontal arrangement carrying roller 2 in roller bed frame 1, each carrying roller 2 is arranged on the face of roller bed frame 1 by rolling bearing units.Carrying roller driving mechanism 3 is made up of the reducing motor be arranged in roller bed frame 1 and sprocket chain strip transmission mechanism.In described roller bed frame 1, be provided with jolt ramming frame 4, this jolt ramming frame 4 is rectangular frame structure.Arrange vibrating motor 5 in the bottom of jolt ramming frame 4, as accompanying drawing embodiment, vibrating motor 5 is symmetrical set a pair.The upper end of jolt ramming frame 4 is provided with the joist 6 be horizontally arranged between carrying roller 2, and this joist 6 is for support sandbox and supporting plate when jolt ramming frame 4 rises.The spring assembling stand 7 protruding from these jolt ramming frame left and right sides is furnished with in the lower part of jolt ramming frame 4, the perpendicular rubber air spring 8 put is respectively equipped with below each spring assembling stand 7, the perpendicular rubber spring 9 put is respectively equipped with, each rubber air spring 8 and form a spring assembly with a rubber spring 9 of its configuration on each spring assembling stand 7.The spring assembly of accompanying drawing embodiment arranges four groups, and this spring assembly is particularly suitable for uniformly in the left and right sides of jolt ramming frame 4 arranging three groups respectively.Arrange a jolt ramming stand 10 in the side of each spring assembly, the lower end of each jolt ramming stand 10 is fixed in Equipment Foundations.As accompanying drawing embodiment, jolt ramming stand about 10 points two parts, are bolted and form entirety, easy access; The lower end of the rubber air spring 8 that each jolt ramming stand 10 is corresponding is fixed on above the base body of this jolt ramming stand 10 lower end, and the upper end of rubber air spring 8 is fixedly connected on below corresponding spring assembling stand 7; Rubber spring assembling post is respectively equipped with on spring assembling stand 7 with below the upper pedestal of jolt ramming stand 10 upper end, rubber spring 9 is provided with central through hole, this rubber spring 9 by its central through hole and the rubber spring above spring assembling stand 7 rubber spring assembled below post and jolt ramming stand 10 upper pedestal assemble post coordinate be assemblied in spring assembling stand 7 and jolt ramming stand 10 upper pedestal between; The rubber air spring 8 of described spring assembly and rubber spring 9 one on next coaxial line arrange.
During the work of this plain bumper, sandbox and supporting plate enter plain bumper position, puddle mixer starts to add sand molding, by the time after molding sand filled by sandbox, rubber air spring 8 is inflated and is driven jolt ramming frame 4 to rise, the roller-way face that sandbox and supporting plate are formed by jolt ramming frame 4 jack-up disengaging carrying roller 2, vibrating motor 5 starts vibration, and molding sand jolt ramming after vibration motor 5 stops vibration.Rubber air spring 8 is inflated and is driven in jolt ramming frame 4 uphill process, and rubber spring 9 is compressed gradually, and at this moment rubber spring plays spacing, levelling, damping effect.Rubber air spring 8 exhaust makes jolt ramming frame 4 decline, and sandbox and supporting plate come back on the roller-way face that carrying roller 2 forms, and carrying roller driving mechanism 3 drives carrying roller 2 to operate and sandbox good for jolt ramming and supporting plate delivered to next station.Two high-performance vibrating motors 5 installed by this plain bumper, carry out incorgruous synchronous rotary, and by jolt ramming frame 4, its exciting force is passed to sandbox and supporting plate, in sandbox, molding sand produces frequency low-amplitude vibration under the effect of vibration acceleration, vibrational energy changes the engagement of the sand grains when the filling of gravity nature, impel sand grains along direction of vibration constantly movement, obtain the uniform sand mold of consolidation under the double action of exciting force and gravity.Because this plain bumper have employed rubber air spring and this combination vibration isolating mechanism of rubber spring, so the impact on factory building foundation when significantly can reduce equipment noise and significantly reduce vibration.
