Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The structure of the main cylinder 10, the sub-cylinder 20, the centering cylinder 60, the anvil 40, the top cylinder 50, and the gantry 70 of the present invention and the connection relationship therebetween will be further described with reference to the following description of the drawings:
referring to fig. 2, the main cylinder 10 and the sub-cylinder 20 are coaxially disposed. The main cylinder 10 is a T-shaped structure, the upper portion of which is a top plate 11, and the bottom of the top plate 11 is a stamping rod 12, and the stamping rod 12 and the top plate 11 are usually integrally formed, and may be fixed by welding or other fixing connection methods. Preferably, the punch rod 12 is disposed at the center of the top plate 11 to make the top plate 11 more uniform when stressed. The secondary cylinder 20 is a cylindrical structure with a first punching channel 21 formed in the middle, the first punching channel 21 is matched with the punching rod 12, and the punching rod 12 is usually inserted into the first punching channel 21. For better performance, lubricating oil is generally applied between the ram rod 12 and the first ram channel 21. The length of the ram 12 is longer than the height of the sub-cylinder 20.
In the implementation, for best implementation, the bottom of the stamping rod 12 should be level with the bottom surface of the secondary cylinder 20 in the rolling stage, and the blank is rolled into a cake when the secondary cylinder 20 and the main cylinder 10 are pressed down simultaneously. During the punching stage, the punching rod 12 will move downwards beyond the bottom surface of the sub-cylinder 20, the length of the protrusion being slightly longer than the thickness of the cake.
A connecting member 30 for controlling the relative positions of the main cylinder 10 and the sub-cylinder 20 is provided between the main cylinder 10 and the sub-cylinder 20, and the connecting member 30 is provided between the lower surface of the top plate 11 and the upper surface of the sub-cylinder 20. Specifically, the connecting member 30 includes three hinge seats, a first hinge seat 31 and a third hinge seat 33, which are respectively installed on the lower surface of the top plate 11, and a second hinge seat 32 installed on the upper surface of the sub-cylinder 20. The first hinge seat 31 is hinged with a first connecting rod 34, the second hinge seat 32 is hinged with a second connecting rod 35, and the third hinge seat 33 is hinged with a hinge cylinder 36. The other ends of the aforementioned first and second connecting rods 34 and 35 and the hinge cylinder 36 are hinged together.
Brief description of the working principle of the connecting member 30: when the hinge cylinder 36 is in a fixed length, the first connecting rod 34, the second connecting rod 35 and the hinge cylinder 36 are in a stable state, and the three are mutually constrained to form a support between the main cylinder 10 and the auxiliary cylinder 20, so that the main cylinder 10 and the auxiliary cylinder 20 are kept in a relatively static state.
When the hinge cylinder 36 contracts, as shown in fig. 4 and 5, because the main cylinder 10 and the secondary cylinder 20 are coaxially arranged, under the interaction between the main cylinder 10 and the secondary cylinder 20, the first connecting rod 34 and the second connecting rod 35 are inclined, so that the distance between the top plate 11 of the main cylinder 10 and the secondary cylinder 20 is shortened, and finally the punching rod 12 extends downwards beyond the secondary cylinder 20, and after the hinge cylinder 36 stops contracting, the positions of the main cylinder 10 and the secondary cylinder 20 are fixed.
Referring to fig. 6, the anvil body 41 is circular and has a channel 411 on its upper surface. A bearing seat 44 is sleeved on the periphery of the anvil plate body 41, a supporting column 43 is fixed below the anvil plate body 41, a second punching channel 42 is arranged at the center of the anvil plate 40, and the center of the second punching channel 42 corresponds to the center of the first punching channel 21. The second punch channel 42 may accommodate passage of a subsequent ram cylinder 50.
Referring to fig. 2 and 3, the centering cylinder 60 includes a ring gear 61 provided on the outer peripheral surface of the bearing housing 44, the ring gear 61 being freely rotatable about the bearing housing 44. The ring gear 61 is driven by external power. In practice, a drive mechanism (not shown) is provided, which comprises a servomotor in the output axial direction, the end of the servomotor being provided with a driving gear, which meshes with the ring gear 61 to enable the ring gear 61 to obtain power.
Also provided beneath the side of the channel 411411 of the anvil body 41 is an open-sided mounting plate 621, the bottom of the mounting plate 621 being connected to the anvil body 41 and having disposed therein a freely rotatable carrier gear 62 in meshing engagement with the gear ring 61. The lower end part of the carrier gear 62 is engaged with the gear ring 61, the upper end part of the carrier gear 62 is engaged with the pushing head 63, the side of the pushing head 63 is provided with teeth, the body of the pushing head is arranged in the channel 411411, when the servo motor drives the gear ring 61 to rotate, the pushing heads 63 in the channels 411411 can be simultaneously pushed towards the center of the second punching channel 42, and thus the blank can stably fall at the center of the anvil body 41, namely the center of the main cylinder 10 and the auxiliary cylinder 20.
The inner end of the pushing head 63 is arranged in a concave arc shape, which can effectively prevent the blanks from sliding out from the side of the pushing head 63 when the pushing head 63 pushes the blanks.
Referring to fig. 2, a top cylinder 50 is disposed below the anvil body 41, the top cylinder 50 includes a connecting plate 51, the connecting plate 51 connects a top rod 52 and a bottom lifting cylinder 53, wherein the top rod 52 and the second punching channel 42 are matched and can be lifted and extended upwards in the process of implementation.
Referring to fig. 2, the present invention further comprises a gantry 70, wherein the gantry 70 comprises two upright posts 71 symmetrically disposed on the anvil body 41, a cross beam 72 is disposed between the top ends of the upright posts 71, and a telescopic rod 73 with a changeable length is disposed below the cross beam 72, and the telescopic rod 73 generally employs an oil cylinder. The bottom of the telescopic rod 73 is fixedly connected with the upper surface of the auxiliary cylinder 20.
The working principle of the invention is briefly described as follows:
when the blank is placed on the anvil body 41, at this time, the top of the top cylinder 50 is flush with the upper surface of the anvil body 41, the external driving mechanism drives the gear ring 61 to rotate, and the gear ring 61 drives the pushing head 63 engaged with the gear ring to move towards the center, so that the centering process is completed. After the centering process is completed, the external driving mechanism is reversed to separate the pusher 63.
After the pushing head 63 leaves, the telescopic rod 73 on the portal frame 70 pushes the main cylinder 10 and the auxiliary cylinder 20 to press down together (at this time, the bottom surface of the main cylinder 10 is flush with the bottom surface of the auxiliary cylinder 20), and the columnar material blank is rolled into a cake-shaped material cake, so that the rolling process is completed.
After the rolling process is completed, the telescopic rod 73 drives the main cylinder 10 and the auxiliary cylinder 20 to retract together, the jacking cylinder 53 pushes the ejector rod 52 to jack open the material cake which may be adhered on the cutting board body 41, then retracts, and retracts until a certain fall is formed between the top surface of the ejector rod 52 and the upper surface of the cutting board body 41, and the height of the fall is larger than the thickness of the material cake.
At the same time, the articulated cylinder 36 begins to contract, so that the bottom of the main cylinder 10 begins to exceed the bottom of the secondary cylinder 20 until the excess is slightly longer than the cake thickness, but not exceeding the height of the aforementioned drop between the push rod 52 and the anvil body 41.
The telescopic rod 73 drives the main cylinder 10 and the auxiliary cylinder 20 to press down again, and the bottom end of the main cylinder 10 exceeds the auxiliary cylinder 20, so that the material cake can be formed by punching, a ring blank is formed by punching, and the purpose of one-step forming is achieved.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
