By adopting technique scheme, when follower drops to minimum point, just can push upper plate, upper plate will extrusion spring, and spring will compressed savings elastic force, when follower starts to rise, the elastic force of savings will discharge, and makes follower better to increase.
The utility model is further set to: described elastic parts also comprises the elastic caoutchouc that is socketed in threaded column bottom and is arranged on lower shoe top.
By adopting technique scheme, elastic caoutchouc has good elasticity, with reaching its needed technique effect here, can either better withstand follower and make it.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of the slide-driving device of punch press of the present utility model;
Fig. 2 is the enlarged drawing of A portion in Fig. 1.
In figure: 1, slide-driving device; 11, follower; 12, driving wheel; 13, threaded column; 2, elastic parts; 21, upper plate; 22, lower shoe.
The specific embodiment
Shown in Fig. 2, the slide-driving device 1 of a kind of punch press of the present embodiment, comprise for the follower 11 that is rotatably connected with slide block, vertically be arranged on threaded column in frame 13 and several driving wheel 12 for being connected with flywheel, described follower 11 is set in threaded column 13, the end face of described driving wheel 12 is all vertical with threaded column 13, wherein two driving wheels 12 are divided into upper and lower two-layer being arranged on threaded column 13 sides, and between relatively reverse rotation, when slide block rises to peak, conflict and be connected with a driving wheel 12, while dropping to minimum point, conflict and be connected with another driving wheel 12.
By adopting technique scheme, when starting punch press, main motor will drive flywheel to rotate, driving wheel 12 will be along with flywheel rotates, follower 11 will rotate along with driving wheel 12, because follower 11 is set in threaded column 13, so can carrying out one in the process of rotating, follower 11 moves up and down, again because slide block is relative being rotatably connected with follower 11, so in the time of follower 11 rotation, slide block is can be along with rotating, and follower 11 is when moving up and down, slide block will be along with moving up and down, when slide block moves downward, mould is pressed onto on material, after forming materials, slide block moves upward, after removal finished product again feeding, slide block moves downward again, carry out again pressing mold effect, produce next group product, owing to there will not be horizontal movement in the process moving up and down at follower 11, so punch press just can not produce vibration, make better align material of mould, reduced the probability of punch press extrusion defective work, increased the punching precision of punch press, wherein two driving wheels 12 connect by planetary gearsets here, a driving wheel 12 is coaxially fixedly connected with the central gear of planetary gearsets inside, another driving wheel 12 is coaxially fixedly connected with planetary outer tooth ring, so just can effectively reach two driving wheels in rotation, it is the effect of reverse rotation, certainly be also not limited only to technique scheme, if a power source is set respectively to two driving wheels, also can reach above needed effect, but can increase like this manufacturing cost of punch press, so the present embodiment does not adopt, and the slide block inside that the present embodiment adopts offers the cylindrical groove passing for threaded column 13, the groove depth of this groove is greater than peak that follower rotates to the distance of minimum point, therefore the length of slide block is also greater than this distance.
Described threaded column 13 bottoms are provided with elastic parts 2.
By adopting technique scheme, when follower 11 drops to minimum point, will be withstood by elastic parts 2, elastic parts 2 can apply an elastic force to follower 11 afterwards, makes follower 11 better to increase.
Described elastic parts 2 comprises upper plate 21 and lower shoe 22, described upper plate 21 is set in threaded column 12, described lower shoe 22 is fixedly connected with threaded column 12 bottoms, and described upper plate 21 is connected by spring with lower shoe 22, when slide block drops to minimum point, conflicts and is connected with upper plate 21.
By adopting technique scheme, when follower 11 drops to minimum point, just can push upper plate 21, upper plate 21 will extrusion spring, and spring will compressed savings elastic force, when follower 11 starts to rise, the elastic force of savings will discharge, and makes follower 11 better to increase.
Described elastic parts 2 also comprises the elastic caoutchouc that is socketed in threaded column 13 bottoms and is arranged on lower shoe 22 tops.
By adopting technique scheme, elastic caoutchouc has good elasticity, with reaching its needed technique effect here, can either better withstand follower and make it.
The utlity model has following advantage: by the setting of follower 11, driving wheel 12 and threaded column 13, just can make follower 11 band movable sliders move up and down, because follower 11 can be with horizontal movement in the process moving up and down, punch press just can not produce vibration like this, mould just can be good at aiming at, and has increased the punching precision of punch press, when starting punch press, main motor will drive flywheel to rotate, driving wheel 12 will be along with flywheel rotates, follower 11 will rotate along with driving wheel 12, because follower 11 is set in threaded column 13, so can carrying out one in the process of rotating, follower 11 moves up and down, again because slide block is relative being rotatably connected with follower 11, so in the time of follower 11 rotation, slide block is can be along with rotating, and follower 11 is when moving up and down, slide block will be along with moving up and down, when slide block moves downward, mould is pressed onto on material, after forming materials, slide block moves upward, after removal finished product again feeding, slide block moves downward again, carry out again pressing mold effect, produce next group product, owing to there will not be horizontal movement in the process moving up and down at follower 11, so punch press just can not produce vibration, make better align material of mould, reduced the probability of punch press extrusion defective work, increased the punching precision of punch press, wherein two driving wheels 12 connect by planetary gearsets here, a driving wheel 12 is coaxially fixedly connected with the central gear of planetary gearsets inside, another driving wheel 12 is coaxially fixedly connected with planetary outer tooth ring, so just can effectively reach two driving wheels in rotation, it is the effect of reverse rotation, certainly be also not limited only to technique scheme, if a power source is set respectively to two driving wheels, also can reach above needed effect, but can increase like this manufacturing cost of punch press, so the present embodiment does not adopt, and the slide block inside that the present embodiment adopts offers the cylindrical groove passing for threaded column 13, the groove depth of this groove is greater than peak that follower rotates to the distance of minimum point, therefore the length of slide block is also greater than this distance.
