Abstract
The utility model relates to a novel become link mechanism, including last connecting rod, lower connecting rod, guidance channel cam and cushion, the top of going up the connecting rod links to each other with the bent axle, the bottom of going up the connecting rod is passed through the cushion and is linked to each other with the top of connecting rod down, remove in the guiding mechanism of cushion by cylinder drive setting on last connecting rod, both sides are provided with the guidance channel cam respectively around the cushion, both sides are installed respectively and are hung the round pin around the connecting rod down, it sets up in the guide slot of cam to hang the round pin to guide slot drive by the cam makes connecting rod up -and -down motion down. Cushion and guidance channel cam are the integrated into one piece structure. The beneficial effects of the utility model are that: simple structure, part accuracy requires lowly, easily processes and assembles, and the reliability is high, and can be adapted to the punching press mechanism of great tonnage. Both ends position that connecting rod length changes can all be under with connecting rod and last connecting rod or connecting rod and cushion locking down, effectively avoid punching press trend change of the times link mechanism's shake.
Description
Technical field
This utility model relates to a kind of novel change linkage.
Background technology
At present, market having the forcing press of various ways become bar linkage structure, wherein high-speed servo forcing press has the change linkage adopting articulated manner.Being characterized in that cushion block and inside connecting rod are hinged by connecting plate, when cylinder promotes cushion block to move, connecting plate promotes inside connecting rod motion, thus changing the length of connecting rod.It has the drawback that once connecting plate length and articulated position are determined, cushion block moves the thrust curve to lower link and namely fixes, it is impossible to make the change of the strict tracking mechanism resistance of thrust.It addition, the impossible size of the general hinged connecting plate of restriction by locus is very big, reliability is affected.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of novel change linkage so that it is have more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of motion being driven guide type actuated by cams connecting rod by cylinder, guide type cam both can produce thrust also can produce pulling force, promote lower link and insert cushion block, utilize pulling force by lower link and cushion block or upper connecting bar locking, it is to avoid because inertia causes the novel change linkage of lower link and upper connecting rod or cushion block disengaging during high speed stamping.
Novel change linkage of the present utility model, including upper connecting rod, lower link, cam and cushion block, the top of described upper connecting rod is connected with bent axle, the bottom of described upper connecting rod is connected with the top of lower link by cushion block, described cushion block is by air cylinder driven, before and after described cushion block, both sides are respectively arranged with cam, described cam is provided with guide groove and constitutes guide type cam, before and after described lower link, both sides are separately installed with extension pin, described extension pin is arranged in cam rail, and is made lower link move up and down by cam rail driving.
Further, described cushion block and cam are formed in one structure.
Compared with prior art, this utility model at least has the advantage that
1, during length of connecting rod variation, the thrust of lower link can be made to match with resistance by rational Design of cam curves by mechanism.
2, simple in construction, element precision requires low, it is easy to processing and assembling, reliability is high, and adapts in large tonnage punching mechanism.
3, length of connecting rod change end positions can by lower link, cushion block or on connecting bar locking, be prevented effectively from the shake of punching press time-varying linkage.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel change linkage described in the utility model；
Fig. 2 is the sectional view of novel change linkage described in the utility model；
Fig. 3 is the structural representation of cushion block in this utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
Referring to Fig. 1-3, this utility model one preferred embodiment is numerical control servo punch press main transmission structure.Owing to bent axle 6 adopts less eccentric throw, the servomotor of less moment of torsion can be adopted to obtain bigger stamping press, and be advantageously implemented high-speed motion.Utilize the feature becoming connecting rod, implement punching press function at connecting rod elongation state, shorten state at connecting rod and carry out the conversion of die location.
The novel change linkage of one described in the present embodiment, including upper connecting rod 1, lower link 2, cam 5 and cushion block 4, the top of described upper connecting rod 1 is connected with bent axle 6, the bottom of described upper connecting rod 1 is connected with the top of lower link 2 by cushion block 4, described cushion block 4 is driven the guiding mechanism arranged along upper connecting rod 1 to move left and right by cylinder 3, before and after described cushion block 4, both sides are respectively arranged with cam 5, described cam 5 is provided with guide groove 8, before and after described lower link 2, both sides are separately installed with extension pin 7, described extension pin 7 is arranged in cam rail 8, and made lower link 2 move up and down by cam rail 8 driving.
Described cushion block 4 and cam 5 are formed in one structure.
The rotary motion of bent axle 6 is become the reciprocating motion needed for punching press by upper connecting rod 1.Having, in upper connecting rod 1, the guiding mechanism being available for cushion block 4 bilateral reciprocation, bottom is provided with the guide frame being connected with lower link 2.Upper connecting rod 1 is provided with the cylinder 3 driving cushion block motion.
Cushion block 4 is driven by cylinder 3 and makes block portion insert between connecting rod 1 and lower link 2 or be fully drawn out between upper connecting rod 1 and lower link 2, to realize the change of length of connecting rod.Cushion block 4 both sides are integrated with cam 5, and in the process that cushion block 4 moves, the guide groove 8 on cam 5 pushes or pull on lower link 2 and moves, and when end positions, lower link 2 is locked by the guide groove 8 on cam 5 with upper connecting rod 1 or cushion block 4.Adopt the cam of guide groove form, be equivalent to utilize two cam contours, thrust can be produced, pulling force can be produced again.Utilize thrust to push lower link 2 open, make cushion block 4 can be successfully inserted at correct position, utilize pulling force to lock as a whole by lower link 2 and cushion block 4 (or upper connecting rod 1).Avoid separating during high-speed motion.
Lower link 2 is connected with hitting bar, and hangs on cam rail 8 by hanging pin 7.When cushion block 4 moves, cam rail 8 drives lower link 2 to move.The guiding mechanism of embedding mutually is had between lower link 2 and upper connecting rod 1.
The above is only preferred implementation of the present utility model, is not limited to this utility model.It should be pointed out that, for those skilled in the art, under the premise without departing from this utility model know-why, it is also possible to make some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
