Description
Technical field
The present invention relates to mechanical punching field.
Background technology
Cutter on existing punching stamping machine is divided into quiet knife and moving knife, and quiet knife and moving knife are supported the use.Before work, punching
Stamping machine can be moved back and forth with adjustment position under the driving of servo-drive system along the conveying direction of production line.During work, section bar exists
Continued through between moving knife and quiet knife, when press bed driving moving knife declines, then moving knife and quiet knife are rushed with credit union to section bar
Cut.
Current punching stamping machine, its quiet knife is to be fixed on quiet knife fixed plate on quiet tool rest, and quiet tool rest is consolidated
It is scheduled in frame, moving knife is installed on moving knife seat with moving knife fixed plate, moving knife seat is connected to hydraulic cylinder.When quiet knife occurs
, it is necessary to change quiet knife during abrasion, then want first pass hull closure to stop production, then dismantle quiet tool rest and the attachment bolt of frame, then tear open
Fall quiet knife fixed plate and quiet tool rest, quiet knife fixed plate and the attachment bolt of quiet knife, then new quiet knife is installed by connecting bolt, most
The gap of moving knife and quiet knife is adjusted afterwards.Time-consuming for this artificial tool changing mode, about needs 1.5 hours~2 hours, substantially reduces
The production efficiency of whole production line.In addition the cut-off part for the bar material that punching comes out has elbow phenomenon, and it cuts section injustice
Whole the problem of.
The content of the invention
The invention is intended to provide a kind of bar material punching and shearing die, to realize that the online switching of cutter in the prior art and bar material are disconnected
Face it is smooth, and avoid bar material cut-off part from problem on deformation occur.
To reach above-mentioned purpose, base case of the invention is as follows：Bar material punching and shearing die, including pedestal, material guide mechanism and
Material cutting-off mechanism, the material guide mechanism includes being provided with the guide sleeve being arranged on pedestal, the guide sleeve to be passed through for bar material
Material guide hole, the porch of the material guide hole is in enlarging shape；
The material cutting-off mechanism includes dynamic material cutting-off mechanism and quiet material cutting-off mechanism, and the dynamic material cutting-off mechanism is arranged on punch press, and dynamic circuit breaker
Expect that mechanism includes upper punching block and upper compressing unit, the upper compressing unit includes upper compact heap, the upper compact heap and punch press
Between be connected with the first stage clip, the lower surface of the upper compact heap is less than the lower surface of upper punching block, the Jing Duanliaojigoubao
Include undershoot block and lower compressing unit, the undershoot block is rotatably connected on pedestal, and the undershoot block is rounded, it is described under
Punching groove is circumferentially with the edge of punching block, the undershoot block center is fixedly connected with rotating shaft, rotating shaft and is coaxially connected with
Be engaged with rack on driven gear, the driven gear, the rack end is connected with cylinder, the lower compact heap and pedestal it
Between be connected with the second stage clip, the lower compact heap is provided with stamped groove, when the second stage clip is in the normal state, the stamped groove, punching
Cut groove and material guide hole is located along the same line, the undershoot block is located at the underface of upper compact heap, the lower compact heap is located at
The underface of upper punching block.
The principle of this programme is：Bar material enters the punching groove and lower compression positioned at punching block the top from material guide hole
In the stamped groove of block, now, punch press drives dynamic circuit breaker material mechanism to move downward, upper compact heap first touch bar material and with undershoot block
Bar material is compressed, punching block quick washing bar material still further below is now gone up, bar material is fractureed.When punching groove is damaged,
In the case of dynamic material cutting-off mechanism upwards motion, start cylinder and pull rack, rack is passed through the driven gear band that is engaged with
Dynamic undershoot block rotates a punching groove, bar material is entered progress punching work in new punching groove.
The advantage of this programme is：1st, by set up upper compact heap and lower compact heap respectively with undershoot block and upper punching block
Cooperating is carried out, the both sides of breaking part, which are compressed, on the one hand is treated to bar material in advance during punching is carried out to bar material,
Prevent bar material from being deformed in the presence of greater impact power；On the other hand, during punching, lower compact heap is also to will be by
The bar material that punching is got off is played a supporting role, and the bar material is in the deformation that horizontality reduces bar material breaking part, so as to ensure
The flatness of section.2nd, by the way that undershoot block is designed into rounded structure and punching groove is set up in the week of undershoot block,
And under the cooperation of driven tooth wheel and rack, when damaged condition occurs in the punching groove in work, online replacing punching can be achieved
The effect of groove, to improve production efficiency.
Preferred scheme 1：Based on scheme improvement, due to being connected with the second stage clip on lower compact heap, operationally, under
Compact heap is moved back and forth under the elastic reaction of the second stage clip, when moving upward to extreme higher position in order to avoid lower compact heap, under
Compact heap is higher than undershoot block upper surface, causes bar material to be smoothly moved to the upper surface of lower compact heap, therefore this programme
In also include position-limit mechanism, the position-limit mechanism includes the support bar being arranged on lower compact heap, offered vertically on support bar
Stroke bar hole, the pedestal is provided with the spacer pin being slidably connected in stroke bar hole, when spacer pin is located at stroke bar hole lower end
When, stamped groove and punching groove are located along the same line, and pass through the cooperation in spacer pin and stroke bar hole, it is ensured that lower compact heap is transported upwards
When moving highest point, stamped groove and punching groove are located along the same line.
Preferred scheme 2：Preferably 1 improvement, between the upper punching block side wall and undershoot block side wall between
Gap is less than 0.1mm, has reached the more smooth effect of the section of bar material.
Preferred scheme 3：Based on scheme or preferred scheme 2 improvement, the punching groove on the punching block joins end to end,
And punching groove is curved, by above-mentioned setting, when phenomenon occurs damaging in a punching groove, punching block is rotated, bar material is along punching
The cambered surface of groove is quickly entered in next punching groove.
Brief description of the drawings
