A manufacturing equipment for sheet metal processing

Abstract

This utility model provides a manufacturing equipment for sheet metal processing, relating to the field of sheet metal processing technology. The equipment includes a frame, a lower mold mounted on top of the frame, and a U-shaped support fixedly connected to the top of the frame. An upper mold is mounted on the inner side of the U-shaped support. In this utility model, coolant from the reservoir flows into a heat exchange tube through a second pipe and pipe joint. The heat exchange tube is installed inside the upper mold via a mounting groove. This allows the heat generated during the bending process of the sheet metal part by the upper and lower molds to be discharged through the coolant in the heat exchange tube, and the coolant can flow back into the reservoir. The heat sinks on the outside of the reservoir can then dissipate heat and cool the coolant. In summary, this utility model effectively dissipates the heat generated during the bending process of sheet metal parts, preventing the bent sheet metal from becoming too hot to handle and facilitating the handling of parts by workers.

Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a manufacturing equipment for sheet metal processing. Background Technology

[0002] Sheet metal work is a comprehensive cold processing technology for thin metal sheets (usually less than 6mm). It includes shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal work are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as a term when assembling parts.

[0003] Although the existing equipment can perform bending operations on sheet metal parts, it does not have a heat dissipation structure. As a result, the heat generated when bending the thin metal sheet cannot be dissipated. The internal energy of the bent part increases, and the temperature rises rapidly. As a result, the sheet metal parts are easy to burn the hands of the workers when they handle them, making it inconvenient for the workers to handle the parts. Utility Model Content

[0004] This utility model provides a manufacturing equipment for sheet metal processing to solve the problem that when bending thin metal sheets, the heat generated cannot be dissipated due to the lack of a heat dissipation structure. This results in increased internal energy at the bending point and a rapid rise in temperature, making it easy for workers to burn their hands when handling the sheet metal parts, which is inconvenient for workers.

[0005] This utility model provides a manufacturing equipment for sheet metal processing, including a frame, a lower mold disposed on the top of the frame, a U-shaped bracket fixedly connected to the top of the frame, an upper mold disposed on the inner side of the U-shaped bracket, a liquid storage tank fixedly installed on the top of the U-shaped bracket, a second pipe fixedly connected to one side of the liquid storage tank, a first control valve fixedly installed on the second pipe, an installation groove opened on the inner side of the upper mold, a heat exchange tube disposed inside the installation groove, the second pipe connected to the heat exchange tube through a pipe joint, the end of the heat exchange tube away from the second pipe connected to the first pipe through a pipe joint, a drive pump fixedly installed on the top of the U-shaped bracket, the first pipe connected to the drive pump, the drive pump connected to the liquid storage tank through a third pipe, a second control valve fixedly installed on the third pipe.

[0006] Preferably, a C-shaped bracket is fixedly connected to the inner wall of the U-shaped bracket, and a driving hydraulic cylinder is fixedly installed on the inner side of the C-shaped bracket; a first connecting plate is fixedly connected to the output end of the driving hydraulic cylinder, a second connecting plate is provided on the inner side of the first connecting plate, and the second connecting plate is fixedly connected to the upper mold.

[0007] Preferably, the first connecting plate and the second connecting plate are internally threaded together with a second fixing bolt.

[0008] Preferably, the bottom of the lower mold is fixedly connected to an mounting plate, and the mounting plate is threadedly connected to the internal part of the frame by a first fixing bolt.

[0009] Preferably, the outer wall of the U-shaped bracket is provided with ventilation slots.

[0010] Preferably, an inlet pipe is fixedly connected to the top of the liquid storage tank, and a third control valve is fixedly installed on the inlet pipe.

[0011] Preferably, a drain pipe is fixedly connected to the bottom of the storage tank, and a fourth control valve is fixedly installed on the drain pipe. Beneficial effects

[0012] Considering the lack of a heat dissipation structure, the heat generated when bending the thin metal sheet cannot be dissipated. The internal energy of the bent part increases, and the temperature rises rapidly. This makes it easy for workers to burn their hands when handling the sheet metal parts, which is inconvenient for them.

[0013] In this invention, during the bending process of sheet metal parts, opening the first control valve allows the coolant inside the accumulator tank to flow into the heat exchange tube through the second pipe and pipe joint. The heat exchange tube is installed inside the upper mold via an mounting groove, allowing the heat generated during the bending process of the sheet metal parts by the upper and lower molds to be discharged through the coolant inside the heat exchange tube. Additionally, starting the drive pump allows the coolant inside the heat exchange tube to be transported to the third pipe through the pipe joint and the first pipe. After opening the second control valve, the coolant in the third pipe can flow back into the accumulator tank. The accumulator tank is equipped with heat dissipation fins on its outside to dissipate heat and cool the coolant. In summary, this invention effectively dissipates the heat generated during the bending process of sheet metal parts, preventing the bent metal sheet from becoming too hot to handle and facilitating the handling of parts by workers.

[0042] Working principle:

[0043] In use, the sheet metal part to be bent is first placed on the lower mold 3, and then the drive hydraulic cylinder 7 fixedly installed inside the C-shaped bracket 6 is activated. The output end of the drive hydraulic cylinder 7 can drive the first connecting plate 8, the second connecting plate 10 and the upper mold 11 to press downward. With the cooperation of the upper mold 11 and the lower mold 3, the sheet metal part can be bent.

[0044] During the bending process of sheet metal parts, the first control valve 19 is opened, allowing the coolant inside the reservoir 17 to flow into the heat exchange tube 13 through the second pipe 18 and pipe joint 14. The heat exchange tube 13 is installed inside the upper mold 11 through the mounting groove 12, allowing the heat generated during the bending process of the sheet metal parts by the upper mold 11 and the lower mold 3 to be discharged through the coolant inside the heat exchange tube 13. Additionally, the drive pump 22 is activated, allowing the coolant inside the heat exchange tube 13 to be transported to the third pipe 20 through the pipe joint 14 and the first pipe 15. After opening the second control valve 21, the coolant inside the third pipe 20 can flow back into the reservoir 17. The reservoir 17 is equipped with heat sinks on its outer side to dissipate heat and cool the coolant. In summary, this invention effectively dissipates the heat generated during the bending process of sheet metal parts, preventing the bent metal sheet from becoming too hot to handle and facilitating the handling of parts by workers.

[0045] Additionally, the operator can unscrew the first fixing bolt 4 from the inside of the mounting plate 2 and the frame 1.

Furthermore, the second fixing bolt 9 can be unscrewed from the inside of the first connecting plate 8 and the second connecting plate 10. Since the second connecting plate 10 is fixedly connected to the upper mold 11, the upper mold 11 can be removed. This invention facilitates the replacement of different models of lower mold 3 and upper mold 11 to meet different sheet metal bending requirements.
