Description

A double head cutting machine

Technical field:

The invention relates to the technical field of cutting machines, in particular to a double-head saw blade cutting machine.

Background technique:

In the process of processing and production, it is often necessary to cut the workpiece. The most commonly used cutting equipment in the prior art is a saw blade cutting machine. When cutting, the workpiece needs to be positioned and clamped first, and then the cutting head moves to the workpiece. During the entire cutting process, the clamping mechanism of the workpiece is fixed and will not move. Therefore, when a workpiece needs to be cut multiple times, or when the cutting is not in place and needs to be re-cut , Only re-positioning and clamping the workpiece, which makes the cutting production efficiency low, and multiple clamping will also affect the cutting accuracy in the production process.

Invention content:

The object of the present invention is to provide a double-head cutting machine, which can improve the production efficiency of cutting, reduce the labor intensity of workers and improve the cutting precision at the same time.

In order to achieve the above object, a double-head cutting machine of the present invention includes a frame on which two working stations are symmetrically arranged on the left and right, and a longitudinal slide rail is installed on each working station, which can be moved along the The cutting head moving along the slide rail is installed on the longitudinal slide rail, the cutting head is driven by hydraulic pressure, and each station is also equipped with a transverse slide rail, which can clamp the workpiece moving along the transverse slide rail The mechanism is installed on the horizontal slide rail; the structure of the clamping mechanism is to fix the clamping block on a bottom plate, and the cylinder is also installed on the bottom plate, and the upper clamping block is located directly above the lower clamping block and fixed on the The piston rod of the cylinder, the bottom plate is movably installed on the horizontal slide rail; the bottom plate is provided with a locking device to lock it; The rails are parallel to the elongated strip-shaped rectangular block. The rectangular block is provided with a T-shaped slot. The T-shaped block matched with the T-shaped slot is placed in the T-shaped slot. A screw is fixed on the T-shaped block. The screw rod is installed on the bottom plate, and a lock nut with a tightening handle is screwed on the screw rod; the cutting machine head is composed of a cutting saw blade, a gear box and a high-speed motor, and the main shaft of the high-speed motor and the gear box input The gears are connected, and the cutting saw blade is fixed on the output shaft of the gear box.

As a preference of the above technical solution, a fixed block is fixed on the frame, a threaded rod is hinged on the fixed block, a rotating hand wheel is fixed at the rear end of the threaded rod, and the front part of the threaded rod passes through the screw rod. The nut is connected with the bottom plate.

As a preference of the above technical solution, the cylinder is installed on a stand, and the lower end of the stand is fixed on the bottom plate.

As a preference of the above technical solution, a waste trolley for placing fertilizer is arranged under the frame.

The beneficial effect of the present invention is that: the present invention does not need to be re-clamped again when the workpiece needs to be cut multiple times, or when the cutting is not in place and needs to be re-corrected, and one-time clamping can complete multiple cuts. It can greatly improve the cutting efficiency. At the same time, it can further improve the cutting accuracy of the workpiece because it does not need to be clamped multiple times. At the same time, in the process of clamping, the clamping of the workpiece is very convenient. The two symmetrically arranged cutting heads can work at the same time, and the clamping and cutting can be rotated to further improve the cutting efficiency.

detailed description:

The following descriptions are only preferred embodiments embodying the principles of the present invention, and do not therefore limit the protection scope of the present invention

As shown in Figures 1 to 7, it is an embodiment of a double-head cutting machine of the present invention, which includes a frame 1, and two work stations are symmetrically arranged on the left and right sides of the frame 1, and each work station A longitudinal slide rail 11 is installed on it, and a cutting head 2 that can move along the slide rail is installed on the longitudinal slide rail 11. The cutting head 2 is driven by hydraulic pressure, and each station is also provided with a transverse slide rail. The rail 12, the workpiece clamping mechanism 3 that can move along the transverse slide rail 12 is installed on the transverse slide rail 12.

In this embodiment, the cutting machine head 2 is composed of a cutting saw blade 23, a gear box 22, and a high-speed motor 21. The main shaft of the high-speed motor 21 is connected to the input gear of the gear box 22, and the cutting saw blade 23 is fixed on the gear box. 22 on the output shaft.

The structure of the clamping mechanism 3 is to fix a clamping block 32 on a base plate 31, and an air cylinder 34 is also installed on the base plate 31. The piston rod, the bottom plate 31 is movably mounted on the transverse slide rail 12 .

A certain block 36 is fixed on the frame 1, a threaded rod 38 is hinged on the fixed block 36, a rotating handwheel 37 is fixed at the rear end of the threaded rod 38, and the front portion of the threaded rod 38 is connected with a screw nut and The bottom plate 31 is connected.

The bottom plate 31 is provided with a locking device 4 for locking it. The locking device 4 is used to lock the bottom plate 31 during cutting so that it will not be displaced during the cutting process.

Specifically in this embodiment, the structure of the locking device 4 is that a long strip-shaped rectangular block 41 parallel to the transverse slide rail 12 is fixed on the frame 1, and a T-shaped slot 42 is opened on the rectangular block 41. , the T-shaped block 43 matched with the T-shaped slot 42 is placed in the T-shaped slot 42, and a screw 44 is fixed on the T-shaped block 43, and the screw 44 is penetrated on the bottom plate 31, and a screw with a tightening handle The locking nut 45 is screwed on the screw rod 44 .

Cylinder 34 is installed on a stand 35, and the lower end of described stand 35 is fixed on the base plate 31, and this makes the upper clamping piece 33 that is fixed on the piston rod of cylinder 34 just be positioned at the right top of lower clamping piece 32.

The bottom of the frame 1 is provided with a waste trolley 5 for placing waste materials. When cutting, there will be waste at the end, and the waste will fall into the waste trolley 5, which facilitates the collection of waste materials and makes the work surface of the equipment cleaner.

When the present invention is working, the workpiece is first placed on the lower clamping block 32, then the cylinder 34 drives the upper clamping block 33 to clamp the workpiece, and then the threaded rod 38 is driven to rotate by turning the handwheel 37 by hand, and the threaded rod 38 drives the base plate 31 to move along the transverse slide rail 12 through the screw nut fixed on the base plate 31, adjusts the base plate 31 to be in a proper position, and then tightens the locking nut 45 so that the T-shaped block 43 and the T-shaped groove 42 are tightly matched. This causes the base plate 31 to be locked on the rectangular block 41 , and the cutting head 2 is hydraulically driven to move, and the cutting saw blade 23 rotating at high speed cuts the workpiece.
