Description

Plastic plate automatic bending machine

technical field

The invention relates to a plastic processing equipment, in particular to an automatic bending device for a plastic plate.

Background technique

At present, in the construction and advertising decoration industry, plastic panels are widely used, and many occasions require bending work. In general construction occasions, simple equipment is used to assist in completion, for example, heating is usually used, combined with simple fixtures for bending.

The disadvantage of the simple bending method is that the processing speed is slow and the forming effect is unstable.

Contents of the invention

The purpose of the present invention is to provide an automatic bending machine for plastic plates with high production efficiency and convenient use, aiming at the deficiencies of the above-mentioned prior art.

The technical scheme that the present invention adopts is as follows:

An automatic plastic plate bending machine is characterized in that it includes a worktable, the upper side of the worktable is hinged with an upper press plate, the lower side of which is hinged with a lower press plate, the upper press plate and The lower press plate is driven by the upper press motor and the lower press motor to rotate along the upper and lower sides of the worktable; the left and right sides of the worktable are respectively hinged with a left bending plate and a right bending plate. plate, the left bending plate and the right bending plate are respectively driven by the left bending motor and the right bending motor to rotate along the left and right sides of the worktable, and the left bending plate and the right bending plate are Heating pipes are arranged on the inner sides of the hinged sides, and the upper pressing plate, the lower pressing plate, the left bending plate and the right bending analysis plate all rotate towards the center of the workbench.

The worktable is installed on two guide rails.

The heating tube is an electric heating tube.

The upper pressing board, the lower pressing board, the left bending board and the right bending board are all rectangular boards, and the width of the upper pressing board and the lower pressing board in the up and down direction is less than half of the width of the worktable.

The heating pipe is installed in the groove.

The beneficial effects of the present invention have:

The structure is relatively simple, easy to use, low cost, can complete the simultaneous bending of both sides of the plastic plate at one time, high production efficiency, good forming effect, stable product forming quality, and because the rotation angle of the left and right bending motors can be set arbitrarily, Therefore, the bending angle of both sides of the plastic plate can also be set arbitrarily. The invention greatly improves the processing speed, effectively reduces the production cost of the enterprise, and improves the operating efficiency and economic benefits of the existing equipment.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figures 1-4, the present invention includes a worktable 11, the worktable 11 is installed on two guide rails 1, and the length of the guide rails 1 is greater than the length of the plastic plate to be processed. The upper side of the worktable 11 is hinged with an upper pressing plate 7, and its lower side is hinged with a lower pressing plate 8, and the upper pressing plate 7 and the lower pressing plate 8 are respectively pressed together by an upper pressing motor 5 and a lower pressing plate. The motor 3 is driven to realize rotation along the upper and lower sides of the worktable 11. The left and right sides of the worktable 11 are respectively hinged with a left bending plate 9 and a right bending plate 10, and the left bending plate 9 and the right bending plate 10 are respectively driven by the left bending motor 6 and the right bending motor 4 Realize rotation along the left and right sides of the workbench 11. Heating tubes 2 are arranged inside the hinged sides of the left bending plate 9 and the right bending analysis plate 10. The heating tubes 2 are electric heating tubes. After electrification, the surface generates heat, driven by a special controller, and the temperature is adjustable. The heating pipe 2 is installed in the groove 12 . The upper pressing plate 7 , the lower pressing plate 8 , the left bending plate 9 and the right bending analysis plate 10 all rotate toward the center of the workbench 11 .

In the present invention, the upper pressing plate 7, the lower pressing plate 8, the left bending plate 9 and the right bending analysis plate 10 are all rectangular plates, and the width of the upper pressing plate 7 and the lower pressing plate 8 in the up and down direction is smaller than the width of the worktable 11 half of.

Working process of the present invention is as follows:

Prepare the plastic plate to be bent first, and adjust the position of each plate on the device according to the plastic plate and processing requirements. After the plastic plate to be processed is placed on the worktable 11, the upper pressing motor 5 and the lower pressing motor 3 work, so that the upper pressing plate 7 and the lower pressing plate 8 are relatively rotated, and the direction is to move inward until the pressing Hold the plastic plate. The heating tube 2 starts to work and heat up, and heats the plastic at the crease until it softens. After a certain period of time, the left bending motor 6 and the right bending motor 4 operate to drive the left bending plate 9 and the right bending analysis plate 10 to rotate inwardly at the same time , to bend the two sides of the plastic plate into shape. In this device, the specification of the plastic plate, the bending distance and the angle can be set arbitrarily within a certain range.

The invention puts the plastic plate in place, presses the start button, and the next whole working process will be carried out automatically.

Other unexplained parts involved in the present invention are the same as the prior art.
