Description

Leaf spring side cutting sewing machine
Technical field
The present invention relates to a kind of leaf spring side cutting sewing machine.
Background technology
Automobile leaf spring must possess sufficiently high elastic deformability, good surface quality, excellent fatigability, plasticity and toughness, and for heavy-duty car, live load and the performance requirement of reality are higher.In use find, the quality of spring end trimming is larger most important to guarantee trimming precision on its fatigue life of impact.
The material that leaf spring often adopts is 60Si 2mn, 50CrV etc., its elastic modelling quantity is comparatively large, often after alignment process, still again warpage may occur, thus, must take suitable clamping work pieces measure when edger designs.Existing spring mechanism clamping insufficient rigidity, must be improved, simultaneously, compare with other stamping products, leaf spring steel plate general thickness used is comparatively large, and punch press tonnage used is also larger, upper and lower mould easily misplaces, and not only trimming precision is difficult to ensure, blade is more easy to wear or destruction also.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of mold integral rigidity high, and the leaf spring side cutting sewing machine that cutter junction is stable.
For achieving the above object, technical scheme of the present invention is:
Leaf spring side cutting sewing machine, comprise die shank, cope match-plate pattern, lower bolster, cutter and bottom knife, described die shank is connected on cope match-plate pattern, cope match-plate pattern and lower bolster positioned opposite, wherein, be also provided with upper slitter bar and bottom knife seat, described upper slitter bar embeds cope match-plate pattern and is connected with cope match-plate pattern, described cutter is connected with upper slitter bar, and described upper slitter bar is provided with shoulder, and upper end and the described shoulder of cutter offset; Bottom knife seat embeds lower bolster and is connected with lower bolster, and described bottom knife is connected with bottom knife seat, and bottom knife seat is also provided with workpiece installing hole.
When adopting technique scheme, first will treat that the leaf spring of trimming is placed on bottom knife seat, and by workpiece installing hole, leaf spring is fixed on bottom knife seat, then forcing press applies downward pressure on die shank, now cope match-plate pattern moves down, after cutter and leaf spring offset, cope match-plate pattern continues to press down, and cutter and bottom knife just can by leaf spring trimmings.In the present invention, upper slitter bar embeds cope match-plate pattern and is connected with cope match-plate pattern, and bottom knife seat embeds lower bolster and is connected with lower bolster, and upper slitter bar and the embedded connection of bottom knife seat, improve the integral rigidity of mould; Secondly, upper slitter bar is provided with the shoulder that can support cutter upper end, can reduce the shearing force of cutter and upper slitter bar junction; Again, bottom knife seat is provided with workpiece installing hole, and clamping work pieces is rigid grasp, good stability.
Further, described lower bolster is provided with the guide plate coordinating upper slitter bar side.Cope match-plate pattern is led by guide plate, avoids cutter to offset, and improves the precision of trimming.
Further, described die shank and cope match-plate pattern are bolted.Bolted mode is convenient to installation and removal, is also convenient to maintenance and changes.
Further, described lower bolster is provided with the baffle plate offseted with guide plate outside guide plate, and described baffle plate is trapezoidal shape.Guide plate also bears the power toward the outer side that bottom knife seat applies in the process of guiding, and this power can cause guide plate to be out of shape, and the baffle plate arranging trapezoidal shape can effectively prevent guide plate to be out of shape.

Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
As shown in Figure 1, a kind of leaf spring side cutting sewing machine, comprise die shank 1, cope match-plate pattern 2, lower bolster 7, cutter 4 and bottom knife 8, die shank 1 is connected on cope match-plate pattern 2, cope match-plate pattern 2 is positioned opposite with lower bolster 7, wherein, also be provided with upper slitter bar 3 and bottom knife seat 9, upper slitter bar 3 embeds cope match-plate pattern 2 and is connected with cope match-plate pattern 2, cope match-plate pattern 2 is provided with the upper mounting groove kept supplying blade bearing 3 and embed, upper slitter bar 3 is connected with cope match-plate pattern 2 bolt, cutter 4 is connected with upper slitter bar 3, as shown in Figure 4, cutter 4 is provided with row's connecting hole, cutter 4 adopts bolt to be connected by connecting hole with upper slitter bar 3, as shown in Figures 2 and 3, upper slitter bar 3 is provided with shoulder 31, upper end and the shoulder 31 of cutter 4 offset, bottom knife seat 9 embeds lower bolster 7 and is connected with lower bolster 7, lower bolster 7 is provided with the lower mounting groove embedded for bottom knife seat 9, bottom knife seat 9 and lower bolster 7 are also for bolt is connected, bottom knife 8 is connected with bottom knife seat 9, as Fig. 5, bottom knife is provided with two row's connecting holes, as shown in Figure 6, bottom knife seat 9 is also provided with workpiece installing hole 91.
In the present embodiment, lower bolster 7 is provided with the guide plate 5 coordinating upper slitter bar 3 side.Cope match-plate pattern 2 is led by guide plate 5, avoids cutter 4 to offset, and improves the precision of trimming.
Die shank 1 and cope match-plate pattern 2 are bolted.Bolted mode is convenient to installation and removal, is also convenient to maintenance and changes.
Lower bolster 7 is provided with the baffle plate 6 offseted with guide plate 5 outside guide plate 5, and baffle plate 6 is trapezoidal shape.Guide plate 5 also bears the power toward the outer side that bottom knife seat 9 applies in the process of guiding, and this power can cause guide plate 5 to be out of shape, and the baffle plate 6 arranging trapezoidal shape can effectively prevent guide plate 5 to be out of shape.
Specific works principle:
