Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting machine, in particular to a gantry type hydraulic cutting machine. BACKGROUND

[0002] The cutting machine is indispensable equipment in some light industry. According to the traditional concept, the cutting machine is a machine for punching processing of non-metallic materials by means of the pressing force of machine movement. The cutting machine is used in the following fields: foamed material, paperboard, textile, plastic material, leather, rubber, packaging material, floor material, carpet, glass fiber, cork and other non-metallic materials are cut by means of the punching force generated by the machine through the die.

[0003] Most of the existing cutting machines place the die on the material, then send the material and the die into the inside of the cutting machine, and finally the cutting machine works to cut the material by applying pressure to the die. In this cutting process, the die needs to be placed on the material manually. Since the die is placed manually, it is not conducive to improving the production efficiency, and the repeated operation of the manual operation also has safety hazards.

[0004] In addition, the cutting stroke of the existing cutting machine is mostly fixed, and the cutting stroke cannot be set according to the thickness of the cutting material, so that the excessive cutting stroke is not conducive to improving the cutting efficiency. SUMMARY

During the lifting of the cross beam, the protrusion touches the travel switch, which provides a stop signal, and by loosening the nut, the height of the travel switch can be adjusted, that is, the lifting height of the cross beam is controlled. Therefore, according to the thickness of the material, the cutting stroke of the cross beam is controlled, and the cutting efficiency is improved.

Starting the hydraulic cylinder can realize the rising or falling of the cross beam.

[0008] Preferably, the inner wall of the shell is fixedly connected with a support, the upper end of both sides of the support is fixedly connected with a damping spring shock absorber, the lower end of both sides of the channel steel is fixedly connected with a baffle, and the baffle is located directly above the damping spring shock absorber. Because the speed needs to be completed during the cutting process, the speed of the cross beam is relatively fast, and therefore the damping spring shock absorber is arranged to buffer and absorb shock.

[0009] Preferably, the lower part of the side wall of the shell is fixedly connected with a mounting foot, and a through hole is arranged in the middle part of the mounting foot. The mounting foot is convenient for fixing the cutting machine by using a nail or the like connecting component.

[0010] Preferably, the side wall of the cross beam is provided with a fixing piece, the fixing piece limits the sliding of the die from the clamping groove, bolts are arranged on the fixing piece in a penetrating manner, and the bolts are threadedly connected with the cross beam. That is, the fixing piece is used for limiting the die, and when the die is replaced, the fixing piece needs to be disassembled, and then the die is pulled out of the clamping groove.

[0011] Preferably, the inside of the shell is provided with a hydraulic pump and an oil tank. The hydraulic pump and the oil tank are used for providing a hydraulic source for the hydraulic cylinder.

[0012] The beneficial effects of the present application are as follows:

[0013] 1. The die is installed on the cross beam, and only the material needs to be placed below the die, for example, the material is placed in a winding manner, without the need for manually placing the die on the material and then feeding into the inside of the cutting machine, so that the work efficiency can be improved, the safety of workers can be ensured, and further, if necessary, the die at the upper end of the cross beam can be replaced with a flat plate, the cross beam serves as a buckling component, the operation mode of the existing cutting machine can be compatible, and the existing needs in the production process can be met.

[0014] 2. The travel switch and the protrusion are arranged, the nut is loosened, the screw rod is slid, the height of the travel switch can be adjusted, the protrusion is fixed on the cross beam, the cross beam rises and touches the travel switch, the travel switch gives a signal for stopping the rising of the cross beam, that is, the height of the rising of the cross beam can be adjusted, which is beneficial to different thicknesses of materials, suitable cutting travel operation, and is beneficial to improving the cutting efficiency.
