Abstract
Bending lock placenta belongs to rail vehicle bender Combined bending placenta field under a kind of bender combined type, and the mould includes the lower tire (1) in basis, multiple combination pieces (2), four hold-down bolts (3), four wing nuts (4) and four screws (5).Mold quantity can be reduced using mould of the present utility model, internal model making cost is saved, saves space；Replacing mold number of times can be reduced, operator's labor intensity is reduced, processing efficiency is improved；Tire is greatly increased than the width of tire under existing bending under the combined type cooperatively formed using the lower tire in multiple combination pieces and basis, and its stability is better than existing bending tire, and mold can be avoided to rock the bending change in size of generation, product quality, rate of reducing the number of rejects and seconds is improved.
Description
Technical field
The utility model belongs to rail vehicle bender Combined bending placenta field, and in particular to a kind of bender
With bending lock placenta under combined type.
Background technology
Trolley coach is needed frequently to change corresponding types according to the different structure and size break to be added with bender
Lower bending lock placenta, existing bender needs all to remove all lower bending lock placentas in use and again
New to change, the Renewal process of its lower bending lock placenta is wasted time and energy, long the time required to directly contributing mold changing, low production efficiency,
The problem of labor intensity is big.
Moreover, in order to produce the thick plate of various material, it is necessary to make the lower bending lock placenta of various different models, it is every kind of
The lower bending lock placenta of specification is made after shaping, and its width dimensions is just fixed and can not changed again, which part width
The lower bending lock placenta utilization rate that is of little use of size it is extremely low, but to occupy many places or memory space, cause it to have enough to meet the need
It is higher with stock control cost.
In addition, the outline narrower width of existing lower bending lock placenta, makes it easily shake in use,
So as to which unexpected change occurs for the bending size for causing workpiece, cause the rise of percent defective.
Utility model content
In order to which the versatility for solving existing lower bending lock placenta is poor, replacement frequency is high, the replacement cycle is long, labor intensity
Greatly, stock control cost is higher, and existing lower bending lock placenta outline narrower width, it is held in use
Easily shake, so as to cause the bending size of workpiece to occur unexpected change, cause the elevated technical problem of percent defective,
The utility model provides bending lock placenta under a kind of bender combined type.
The utility model technical solution adopted for solving the technical problem is as follows：
Bending lock placenta under a kind of bender combined type, it includes the lower tire in basis, multiple combination pieces, four compressions
Bolt, four wing nuts and four screws, the lower tire in the basis is total to by rectangular recess bottom surface and two rectangular recess side walls
With the rectangular through slot to be formed is surrounded, rectangular through slot is along its length respectively in the bottom of a rectangular recess side wall front end face with after
The bottom symmetrical of end face is provided with a screw mounting hole；The screw mounting hole threaded connection corresponding with one of each screw；Often
A first hold-down bolt mounting groove, the first pressure are respectively equipped with the middle part of the middle part of individual rectangular recess side wall front end face and rear end face
Tight bolt mounting groove is located at the top of rectangular recess bottom surface；Multiple combination pieces are symmetrically divided into two along rectangular through slot short side center line
A second hold-down bolt mounting groove is respectively equipped with the middle part of group, the middle part of each combination piece front end face and rear end face；Each
The bolt end of hold-down bolt is respectively positioned in rectangular through slot, and the end of thread of each hold-down bolt sequentially passes through multiple second and compressed
Wing nut threaded connection corresponding with one after bolt mounting groove and a hold-down bolt mounting groove.
Mould of the present utility model also includes multiple backing plates, and each backing plate is sandwiched between two combination pieces.
The beneficial effects of the utility model are as follows：
1) using bending lock placenta under the combined type, mold quantity can be reduced, it is to avoid make a large amount of different in width
Mold, saves internal model making cost, saves space.
2) using bending lock placenta under the combined type, replacing mold number of times can be reduced, different in width mold is being needed
When, it is that can be achieved only to change backing plate, reduces mould replacing time, improves processing efficiency.
3) change backing plate time saving and energy saving, effectively reduce operator's labor intensity.
4) width of the tire than tire under existing bending under the combined type that pieces are cooperatively formed with the lower tire in basis is combined using multiple
Greatly increase, its stability is better than existing bending tire, mold can be avoided to rock the bending change in size of generation, product matter is improved
Amount, rate of reducing the number of rejects and seconds.
