Description

Forced waste material removing mechanism

Technical Field

The utility model relates to a move back waste material mechanism, especially relate to a force and move back waste material mechanism.

Background

Stamping is mainly classified according to the process and can be divided into two major types, namely a separation process and a forming process. The separation process, also called blanking, is intended to separate the stamping from the sheet along a certain contour line, while ensuring the quality requirements of the separation section (table 1). The forming process aims to enable the plate to generate plastic deformation under the condition of not breaking a blank so as to manufacture a workpiece with a required shape and size. In actual production, multiple processes are often applied to one workpiece. Blanking, bending, shearing, deep drawing, bulging, spinning and correcting are several main stamping processes.

When punching, shearing and trimming workpieces (i.e. products), waste materials are required to be blanked. When the product shape is flat, the waste material can naturally slide down while being cut off, when the product shape is complex, in order to ensure that the product cannot deform while being cut off, the profiling design is usually carried out on the trimming knife block, namely, the surfaces of the upper trimming knife and the lower trimming knife are profiled with the waste material, the lower surface (namely the profile) of the upper trimming knife can be properly abducted while being profiled, so that the upper die is prevented from being clamped, the profiling of the lower die is completely attached, the waste material can be attached to the knife block after being cut off due to the profiling of the lower trimming knife, the material cannot be smoothly removed, the normal production is influenced, the labor cost is greatly increased through the manual material removal mode, and the production efficiency is reduced.

In view of the above, there is a need for improvements in the prior art solutions.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a force and move back waste material mechanism to overcome above-mentioned problem.

In order to solve the technical problem, the utility model discloses a technical scheme be: provided is a forced waste material withdrawing mechanism, comprising: the material lifting hook comprises an upper die base and a lower die base, wherein an upper die trimming knife block is arranged on the upper die base, a material lifting hook fixing seat is arranged on the upper die trimming knife block, a material lifting hook is arranged at the lower end of the material lifting hook fixing seat, the material lifting hook is connected with the material lifting hook fixing seat through a penetrating pin, and a lower die trimming knife block is arranged on the lower die base.

Furthermore, the upper die trimming cutter block and the lower die trimming cutter block are both provided with waste-imitating molded surfaces.

Furthermore, an R angle clearance is formed in the waste imitation molded surface of the upper die trimming knife block, the molded surface is emptied by 0.2mm, and the waste is prevented from being clamped on the upper die trimming knife block after stamping.

Furthermore, the lower die trimming knife block is provided with a material sliding inclined plane.

Furthermore, the lower end of the lifting hook fixing seat is hollowed out, and the lifting hook is folded to the hollowed-out position during punching and trimming.

The utility model has the advantages that: the hook can be conveniently folded by blocking the material lifting hook by a product during stamping, the hook is positioned below a waste part of the product when the stamping is finished by the dead weight of the hook, and the waste is taken up from the lower die trimming cutter block by the action of the hook during returning so as to smoothly strip the material.

Drawings

FIG. 1 is a schematic illustration of an embodiment belt scrap configuration.

FIG. 2 is a schematic view of an embodiment of the structure without the scrap material.

The parts in the drawings are numbered as follows: 1. the device comprises an upper die trimming knife block, 2, a lifting hook fixing seat, 3, a lifting hook, 4, a pin, 5, a lower die trimming knife block, 6 and waste materials.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, an embodiment of the present invention includes: the upper die is provided with an upper die trimming knife block 1, the upper die trimming knife block 1 is provided with a lifting hook fixing seat 2, the lower end of the lifting hook fixing seat 2 is provided with a lifting hook 3, the lifting hook 3 is connected with the lifting hook fixing seat 2 through a through pin 4, the lower die seat is provided with a lower die trimming knife block 5, the upper die trimming knife block 1 and the lower die trimming knife block 5 are both provided with waste imitation profiles, an R-angle clearance is formed in the waste imitation profile of the upper die trimming knife block 1, the profile is emptied by 0.2mm, waste after stamping is prevented from being clamped on the upper die trimming knife block, and the waste imitation profile of the lower die trimming knife block 5 is attached with waste.

Specifically, the lower end of the lifting hook fixing seat 2 is hollowed out, the hollowed-out part is matched with the lifting hook 3 in shape, and the lifting hook 3 is folded to the hollowed-out part during stamping and trimming.

The utility model relates to a force and move back theory of operation of waste material mechanism as follows: the product enters a trimming procedure, and the waste material part of the product is arranged below the upper die trimming cutter block and corresponds to the imitated waste material molded surface of the upper die trimming cutter block; when the stamping starts, the upper die base drives the upper die trimming cutter block to move downwards, and the material lifting hook is contacted with the waste material part of the product and is retracted to the hollow area of the material lifting hook fixing base; when the product is punched to the bottom, the material lifting hook moves to the position below the product, the material lifting hook is naturally opened under the action of self weight, meanwhile, the product is trimmed, and the waste material part is positioned between the upper die trimming cutter block and the lower die trimming cutter block; when the scrap removing device retreats, the upper die base drives the upper die trimming knife block to move upwards, the material lifting hook hooks one side of the scrap to move upwards together, so that the scrap is separated from the lower die trimming knife block, and the scrap falls along the material sliding inclined plane of the lower die trimming knife block due to self weight.

The utility model relates to a force and move back waste material mechanism: the hook can be conveniently retracted by blocking the material lifting hook by a product during stamping, the hook is positioned below the waste part of the product during bottom stamping by the self weight of the hook, and the waste is taken up from the lower die trimming cutter block by the action of the hook during retraction to smoothly strip the material; the mechanism has small structure and low cost, and can continuously produce the die and reduce the downtime.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
