Description

Technical Field

[0001] The utility model relates to the technical field of stamping and forming devices, in particular to a stamping and forming device for processing box plates of a dump truck box. Background Art

[0002] The dump truck can lift the cargo box through the hydraulic device and unload the cargo inside the vehicle. During the processing of the box plate of the cargo box, the plate can be extruded through the stamping forming device.

[0003] The inventor discovered during the process of implementing the utility model that:

[0004] Patent document CN111375698A discloses a sheet metal stamping device. This invention provides a groove around the punching groove and a mechanical ejection structure consisting of a compression spring and an ejector block in the groove to facilitate ejecting the product from the punching groove after the punching is completed.

[0005] However, in the prior art, the stamping forming device uses a stamping plate to squeeze the sheet into the interior of the forming groove for extrusion forming. However, the deformation of a single stamping is too large, which can easily cause the sheet to crack. In addition, when the sheet is demolded after forming, the support force of the spring-supported demolding method is too low, resulting in the sheet not being able to be demolded normally. Therefore, there is a need to improve the prior art. Summary of the Invention

[0006] In order to solve the problems in the prior art that a single stamping method easily causes damage to the plate and insufficient spring support force easily causes failure to demould, the utility model proposes a dump truck cargo box processing box plate stamping and forming device.

A material return mechanism is provided inside the forming seat, and the upper end of the forming seat is fixedly connected to two fixed frames symmetrically distributed front and back, and a plurality of evenly distributed support rods are slidably connected to the interior of the fixed frame, and the upper end of the support rod is fixedly connected to the frame, and a rotating wheel is installed inside the frame through a bearing, and a conveyor belt is sleeved on the outer side of the rotating wheel. A driving motor is fixedly installed on the outer side of the frame, and a spring is provided on the outer sleeve of the support rod.

[0008] Preferably, the depths of the two forming grooves are different, and a plate is placed on the upper end of the conveyor belt. When the plate is formed, it can be formed first through the shallower forming groove and then through the deeper forming groove for secondary forming, which can effectively avoid the plate from breaking due to excessive single stretching.

[0009] Preferably, the output shaft of the driving motor is fixedly connected to the rotating wheel, the conveyor belt is in contact with the frame, and the conveyor belt can drive the plate to move.

[0010] Preferably, one end of the spring 1 is fixedly connected to the fixing frame, and the other end of the spring 1 is fixedly connected to the frame, and the spring 1 can support the frame through elastic force.

[0011] Preferably, the material stripping mechanism includes a material stripping plate, the interior of the forming groove is slidably connected to the material stripping plate, the lower end of the material stripping plate is fixedly connected to a push rod, the lower end of the push rod is fixedly connected to a driving plate, a screw is installed inside the forming seat through a bearing, a servo motor is fixedly installed inside the forming seat, an internal threaded tube is fixedly connected inside the driving plate, and the push rod can push out the formed sheet through the material stripping plate.
