Description

a shearing machine

technical field

The utility model relates to the field of mechanical equipment, in particular to a shearing machine.

Background technique

Shearing machine is a kind of shearing equipment widely used in machining. It can cut steel plate materials of various thicknesses. The thickness of the metal plate applies a shear force, so that the plate is broken and separated according to the required size to obtain a blank with a straight edge, which is mainly used for blanking and other types of work. The existing shearing machine cannot continue to stabilize the plate during the shearing process. The compression of the plate is prone to force movement during shearing, which will affect the final plate size, cause the plate to be scrapped, and easily cause damage to the shearing blade. Generally, the structure of the shearing machine is complex and the manufacturing cost is high. Ordinary shearing machines The upper part of the machine is an open structure, which is easy to cause damage to the equipment when used for a long time, with a short service life and potential safety hazards.

Utility model content

The object of the present invention is to provide a shearing machine with the advantages of convenient operation, reliable performance, stable operation, simple structure and low cost in view of the defects and deficiencies of the prior art.

In order to solve the existing problems of the background technology, the present invention adopts the following technical solutions: a shearing machine, including a frame, a knife rest, a motor, a gear, a reducer, a presser and a main shaft; There is a knife rest; the knife rest includes an upper knife rest and a lower knife rest; the lower knife rest is arranged on the workbench; the upper knife rest is movably connected with the main shaft through a connecting rod; the main shaft is provided with Motor; the motor is connected to the transmission mechanism; it includes gears, reducers, power switches and brakes; the upper end of the presser is provided with an elastic compression spring mechanism, and one end is connected to the upper knife rest.

Preferably, the motor, the gear and the main shaft are all provided with protective sleeves.

Preferably, the brake is a pedal brake.

When the utility model is operated and used, the plate is placed on the workbench and fixed under the presser, the motor is turned on to drive the gear to rotate, the speed reducer slows down the speed, the brake is stepped on, and the knife rest is placed on the body through the connecting rod The reciprocating movement is made in the guide rail to complete the shearing work.

The utility model has beneficial effects: it has the advantages of convenient operation, reliable performance, stable operation, simple structure and low cost.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the utility model, but not as a limitation to the utility model.

As shown in Figure 2, the present specific embodiment adopts the following technical solutions: a shearing machine, including a frame 1, a knife rest, a motor 8, a gear 7, a speed reducer 10, a presser 5 and a main shaft 11; The top of the frame 1 is provided with a knife rest; the said knife rest comprises an upper knife rest 12 and a lower knife rest 6; said lower knife rest 6 is arranged on the workbench 4; The main shaft 11 is movably connected; the main shaft 11 is provided with a motor 8; the motor 8 is connected to the transmission mechanism; it includes a gear 7, a reducer 10, a power switch 14 and a brake 3; the upper end of the presser 5 is provided Elastic clip spring mechanism 13 is arranged, and one end is connected with upper knife rest 12.

Preferably, the motor 8, the gear 7 and the main shaft 11 are all provided with a protective cover 2 on the outside.

Preferably, the brake 3 is a pedal brake.

The working principle of this specific implementation: when cutting the board, place the board on the workbench and fix it under the presser, the lower knife rest is fixed above the frame and does not move, the motor turns on to drive the gear to rotate, the reducer slows down the speed, and the foot Step on the brake, and make the upper knife rest reciprocate in the guide rail on the machine body through the connecting rod to complete the shearing work. The presser includes two elastic compression spring mechanisms and a horizontal pressing plate connected to the two elastic compression spring mechanisms in a detachable manner. The upper and middle knife rests are pressed down, and the presser is pressed to achieve continuous and stable pressing of the plate to prevent it from moving. There is a protective cover on the outside to block the dust, which is convenient for equipment maintenance and increases the service life. Improper operation, manual contact with the transmission mechanism will lead to unnecessary accidents.

The above is only used to illustrate the technical solution of the utility model without limitation, other modifications or equivalent replacements made by those skilled in the art to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model , should be covered in the scope of the claims of the present utility model.
