Description

Technical Field

[0001] This utility model belongs to the field of connecting mold technology, and relates to a feeding mechanism and a continuous mold including the same. Background Technology

[0002] When producing parts using progressive dies, the feeder at the front of the punch press typically feeds the coiled material into the die, and the feeding is performed progressively according to the die's pitch.

[0003] In conventional molds, the floating block device is made of forgings. During the feeding process, the forging and the coil are always in sliding contact. Different coils exhibit different characteristics. For example, aluminum coils are relatively soft and are always in sliding contact during the feeding process, which may scratch the surface of the sheet, damage the appearance requirements of the parts, easily produce defective parts, reduce the product qualification rate, and increase the manufacturing cost of finished products. Utility Model Content

[0004] The present invention aims to provide a feeding mechanism that can effectively prevent the material strip from being scratched during the conveying process, so as to effectively improve the product qualification rate of the connecting mold when producing parts.

[0005] This utility model provides a feeding mechanism, which is applied to a progressive die for conveying the strip material to be stamped; it includes a feeder, a feeding support frame, a floating plate, and a steel plug.

[0006] The material strip is wound onto the drum of the feeder and conveyed by the feeder;

[0007] The feeding support frame is installed on the lower die of the continuous die and is used to support and guide the material strip conveyed by the feeder.

[0008] Both the floating plate and the steel stopper are mounted on the feeding support frame. The floating plate is used to support the strip during stamping and forming, and the steel stopper is used to support the strip during transmission.

[0009] Furthermore, the distance between the upper end face of the steel plug and the upper end face of the feeding support frame is greater than the distance between the upper end face of the floating plate and the upper end face of the feeding support frame.

[0010] Furthermore, multiple strips of material arranged side by side are wound on the drum of the feeder;

[0011] The feeding support frame is also provided with guide members for mutually limiting and guiding two adjacent material strips. The guide members are provided in multiple sets that are spaced apart from each other along the conveying direction of the material strips. Each set of guide members is provided with at least two pieces that are spaced apart from each other along the distribution direction of the multiple material strips.

[0012] Furthermore, the floating material plate is provided with multiple sets of floating material plates that are spaced apart from each other along the conveying direction of the material belt, and each set of floating material plates is provided with multiple pieces that correspond one-to-one with the multiple material belts arranged in parallel.

[0013] Furthermore, the steel-blocking component is provided with multiple sets of components spaced apart from each other along the conveying direction of the material belt, and each set of steel-blocking components is provided with multiple components that correspond one-to-one with the multiple material belts arranged in parallel.

[0014] As a further embodiment of this utility model, this utility model also provides a continuous die, including the feeding mechanism, upper die and lower die as described above;

[0015] The feeding mechanism and the lower die are arranged side by side along the conveying direction of the material strip, and the material strip is conveyed to the lower die by the feeder;

[0016] The upper die is mounted on the worktable of the punch press. The punch press drives the upper die to move in the vertical direction so as to form a mold closing or mold opening movement with the lower die.

[0017] The lower die is installed on the lower worktable of the punch press.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The feeding mechanism provided by this utility model is to continuously convey the material belt by setting up a feeder; and to support the conveying material belt by setting up a steel plug to avoid the material belt directly contacting the floating plate and causing scratches. This utility model has the characteristics of simple structure, convenient operation, strong applicability and cost saving.

[0020] (2) In order to overcome the problems existing in the related technologies, the problem of easy scratching of the surface of soft aluminum profiles and parts with extremely high surface requirements has been solved. When conventional structures cannot eliminate this technical difficulty, this structure occupies little space and can solve the scratching problem in the limited mold space, saving mold manufacturing and after-sales maintenance costs.

[0021] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description
