Description
Technical field
The utility model is related under intelligent Manufacturing Technology field more particularly to a kind of high speed motor car wire casing die for punching
Backing plate.
Background technology
In the prior art, the processing for the cable-through hole having on high speed motor car wire casing is usually to be completed on drilling machine, by
It is vertical processing to drill in drilling machine, and can only bore a hole every time, in order to ensure that the cable-through hole of high speed motor car wire casing processes essence
Degree, needs repeatedly to carry out high accuracy positioning, causes processing efficiency low, it is difficult to meet the requirement of batch production, and drill out
Hole Form and position error is big, precision is low, and has more cable-through hole, the difficulty for increasing drilling of bigger on high speed motor car wire casing
Degree.
Invention content
The utility model provides a kind of lower bolster of wire casing die for punching, it is intended to realize high using die for punching processing
Quick-action fare slot improves the cable-through hole machining accuracy of high speed motor car wire casing, reduces the cable-through hole machine-shaping of high speed motor car wire casing
Hole Form and position error afterwards.
Specific technical solution provided by the utility model is as follows：
A kind of lower bolster of high speed motor car wire casing die for punching provided by the utility model is provided on the lower bolster
2 keep away a hole, 8 the first dowel pin holes, 4 the second dowel pin holes, 8 lower die screw holes and 8 upper mold screw holes, 1 enter sub-aperture,
Wherein, it is described enter sub-aperture be arranged in the center of the lower bolster, it is described enter sub-aperture edge be provided with threading hole, 2
The upper and lower ends kept away a hole and be separately positioned on the lower bolster, 8 upper mold screw holes are respectively along the lower bolster
Edge is arranged.
Optionally, a hole of keeping away is square structure, and 8 first dowel pin holes are in that two row are symmetrical arranged respectively, 4 institutes
State the second dowel pin hole respectively be in 2 row be arranged it is described enter sub-aperture four edges.
The beneficial effects of the utility model are as follows：
The utility model embodiment provides a kind of lower bolster of high speed motor car wire casing die for punching, is provided with 2
Keep away a hole, 8 the first dowel pin holes, 4 the second dowel pin holes, 8 lower die screw holes and 8 upper mold screw holes, 1 enter sub-aperture,
In, enter sub-aperture and be arranged to enter the edge of sub-aperture in the center of the lower bolster and be provided with threading hole, 2 are kept away a hole difference
Upper and lower ends in lower bolster are set, and 8 upper mold screw holes are arranged along the edge of lower bolster respectively；The lower bolster is used for high quick-action
Vehicle group wire casing die for punching, dowel pin hole, lower die screw hole, upper mold screw hole and enters sub-aperture mutual cooperation, and enters sub-aperture
Edge is provided with threading hole, may be implemented to process high speed motor car wire casing using die for punching, improves high speed motor car wire casing
Cable-through hole machining accuracy reduces the hole Form and position error after the cable-through hole machine-shaping of high speed motor car wire casing, reduces its difficulty of processing,
Improve the processing efficiency of high speed motor car wire casing.
Description of the drawings
Fig. 1 is a kind of structural representation of the lower bolster of high speed motor car wire casing die for punching of the utility model embodiment
Figure.
Specific implementation mode
Below in conjunction with Fig. 1 to the lower bolster of high speed motor car wire casing die for punching of the utility model embodiment a kind of into
Row detailed description.
Refering to what is shown in Fig. 1, a kind of lower bolster for high speed motor car wire casing die for punching that the utility model embodiment provides,
It is provided with 2 and keeps away a hole 1,8 the first dowel pin hole, 2,43,8, the second dowel pin hole lower die screw holes 4 and 8 upper mold spiral shells
Wire hole 5,1 enters sub-aperture 6, wherein enters sub-aperture 6 and is arranged to enter the edge of sub-aperture 6 in the center of lower bolster and be provided with threading
The upper and lower ends that a hole 1 is separately positioned on lower bolster are kept away in 7,2, hole, and 8 upper mold screw holes 5 are set along the edge of lower bolster respectively
It sets.
The lower bolster of the utility model embodiment is used for high-speed EMUs wire casing die for punching, dowel pin hole, lower die screw
Hole, upper mold screw hole and enter sub-aperture mutual cooperation, and the edge for entering sub-aperture is provided with threading hole, may be implemented to use punching
High speed motor car wire casing is processed with mold, improves the cable-through hole machining accuracy of high speed motor car wire casing, reduces the mistake of high speed motor car wire casing
Hole Form and position error after string holes machine-shaping reduces its difficulty of processing, improves the processing efficiency of high speed motor car wire casing.
Refering to what is shown in Fig. 1, it is square structure to keep away a hole 1,8 the first dowel pin holes 2 are in that two row are symmetrical arranged respectively, 4 the
