Abstract
The utility model relates to a device for eliminating stamping marks during the bending process of metal, which comprises a bending machine, wherein an upper die and a lower die are arranged in the bending machine, the stamping surface of the upper die is covered with an upper buffer layer, and the stamping surface of the lower die is covered with a lower buffer layer. By utilizing the bending machine to stamp a metal plate, the surface hardness of the upper buffer layer and the lower buffer layer is less than that of the metal plate to be processed, the surface of the upper die, which is in contact with the metal plate, is covered with the upper buffer layer, and the surface of the lower die, which is in contact with the metal plate, is covered with the lower buffer layer. During stamping, the upper die and the lower die can not generate the stamping marks nearby a bending position. By adopting the device, the product quality is improved.
Description
Technical field
The utility model relates to the operation transport field, relates in particular to the metal cold processing technique, particularly metal folding machine, and concrete is a kind of device of eliminating the punching press vestige in metal folding processing.
Background technology
In the prior art, utilize bender that metallic plate is carried out Bending Processing.Be provided with upper die and lower die in the bender, metallic plate to be processed is arranged on the counterdie, and patrix is to the punching press of counterdie direction, with the metallic plate bending and molding.Because upper die and lower die are made by the steel material usually; when processing aluminium alloy plate or corrosion resistant plate; the material hardness of upper die and lower die is greater than aluminium alloy plate or corrosion resistant plate; patrix or counterdie can stay the punching press vestige near the surface aluminium alloy plate or the corrosion resistant plate bending part, it is attractive in appearance to influence product.
The utility model content
The purpose of this utility model is to provide a kind of method of eliminating the punching press vestige in metal folding processing, and the described this device of eliminating the punching press vestige in metal folding processing will solve near the technical problem that produces the punching press vestige when bender is processed aluminium alloy plate or corrosion resistant plate in the prior art bending part.
This device of eliminating the punching press vestige in metal folding processing of the present utility model is made of bender, be provided with upper die and lower die in the described bender, wherein, be coated with one on the stamping surface of patrix and go up cushion, be coated with a bottom breaker on the stamping surface of counterdie.
Further, described upward cushion and bottom breaker are made of rubber slab.
Perhaps, described upward cushion and bottom breaker are made of the ptfe plastic plate.
Perhaps, described upward cushion and bottom breaker are made of the metal stereotype.
Operation principle of the present utility model is: utilize the bender stamped sheet metal, the case hardness of last cushion and bottom breaker is all less than the case hardness of metallic plate to be processed, last cushion covers the contact-making surface of patrix and metallic plate, and bottom breaker covers the contact-making surface of counterdie and metallic plate.When punching press, upper die and lower die can not produce the punching press vestige near bending part.
Concrete, the bender described in the utility model, upper die and lower die all can adopt known schemes of the prior art, the known technology of relevant bender, upper die and lower die, and those skilled in the art all understands, does not repeat them here.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model covers cushion on the upper die and lower die of bender, the case hardness of cushion is less than the case hardness of metallic plate to be processed, and when punching press, upper die and lower die can not produce the punching press vestige near bending part.The utility model has improved product quality.
Description of drawings:
Fig. 1 is a structural representation of eliminating the device of punching press vestige in metal folding processing of the present utility model.
The specific embodiment:
Embodiment 1:
As shown in Figure 1, the device of eliminating the punching press vestige in metal folding processing of the present utility model is made of the bender (not shown), be provided with patrix 1 and counterdie 2 in the described bender, wherein, be coated with one on the stamping surface of patrix 1 and go up cushion 4, be coated with a bottom breaker 5 on the stamping surface of counterdie 2.
Further, described cushion 4 and the bottom breaker 5 gone up is made of rubber slab.
Perhaps, described upward cushion 4 and bottom breaker 5 are made of the ptfe plastic plate.
Perhaps, described upward cushion 4 and bottom breaker 5 are made of the metal stereotype.
The course of work of present embodiment is: utilize bender stamped sheet metal 3, metallic plate 3 is aluminium alloy plate or corrosion resistant plate, the case hardness of last cushion 4 and bottom breaker 5 is all less than the case hardness of metallic plate to be processed 3, last cushion 4 covers the contact-making surface of patrix 1 and metallic plate 3, and bottom breaker 5 covers the contact-making surface of counterdies 2 and metallic plate 3.When punching press, patrix 1 and counterdie 2 can not produce the punching press vestige near bending part.
Claims (4)
1. device of in metal folding processing, eliminating the punching press vestige, constitute by bender, be provided with upper die and lower die in the described bender, it is characterized in that: be coated with one on the stamping surface of patrix and go up cushion, be coated with a bottom breaker on the stamping surface of counterdie.
2. the device of eliminating the punching press vestige in metal folding processing as claimed in claim 1 is characterized in that: described upward cushion and bottom breaker are made of rubber slab.
