Description

Technical Field

[0001] The utility model relates to the technical field of door panel shaping, in particular to a door panel shaping machine for excavators. Background Art

[0002] The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rocks. From the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction.

[0003] During the production and processing of the door panels on the excavator, the raw materials of the panels need to be pressurized and shaped before they can be assembled and installed with other structures of the excavator. The prior art generally uses a hydraulic shaping machine to pressurize and shape the door panels. When using the shaping machine, the mold must first be installed and positioned, and then the processing and shaping operation can be performed after the positioning is completed. The mold is generally fixed to the mold seat by bolts. However, in order to be able to fix the mold accurately and quickly, it takes workers a certain amount of time to fix the bottom mold, which will affect the processing efficiency. When different types of door panels need to be processed, different molds need to be replaced, which often takes a lot of time to replace, reducing work efficiency. Moreover, after the bolts and other fixings are disassembled and installed many times, wear will occur between the threads, making the mold positioning unstable and inaccurate, affecting the production quality of the shaping machine.

[0005] An embodiment of the present application provides an excavator door panel shaping machine, comprising a mold body, a workbench and a positioning device; the mold body is located on a mold base; the mold comprises an upper mold and a lower mold; the positioning device comprises a push plate, an electric telescopic rod and a fixed block; the positioning devices are symmetrically arranged on both sides of the mold base, with a total of two groups; a sponge suction cup is provided on the side of the push plate in contact with the mold; sliders are provided at both sides of the bottom of the push plate; an infrared sensor is provided in the push plate at the top of the slider; a fixed block is provided at one end of the electric motor connected to the push plate; a rubber buckle is provided on one side of the fixed block.

[0006] Furthermore, the workbench includes a hydraulic support, a table top and four table legs; the mold base is located in the middle of the table top surface.

[0007] Furthermore, the hydraulic support is arranged on the table top, and comprises a hydraulic cylinder, a top plate and a column support; the hydraulic cylinder is located at the center of the top plate, and the hydraulic cylinder is provided with a hydraulic push rod.

[0008] Furthermore, the upper mold is connected to the hydraulic push rod through threads; and heating plates are provided inside the upper mold and the lower mold.

[0009] Furthermore, the sponge suction cup is connected to an external power source.

[0010] Furthermore, the table top is provided with a slide rail, and the slide rail and the slider cooperate with each other.

[0011] Furthermore, the infrared sensor of the mold base is connected to the start switch of the electric telescopic rod.

[0012] The beneficial effect of the utility model is that when the infrared sensor at the bottom of the push plate senses the lower mold, the electric telescopic rods on both sides are turned on to drive the push plate to move toward the middle to clamp the middle mold; at the same time, the strong adsorption force of the sponge suction cup is fully utilized to fix the bottom mold; the device has a simple structure and does not need to be repeatedly fixed with screws, and the sponge suction cup can adsorb molds of various shapes, which has a wider range of applications than existing molds.
