Description

Human hydraulic bending machine

technical field

The utility model relates to the technical field of bending machines.

Background technique

The bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is composed of a seat shell, a coil and a cover plate, the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece with side walls can be processed, and the operation is also very simple.

At present, during the inspection and maintenance of substations or power distribution rooms, electro-hydraulic bending machines are used for all copper (aluminum) row bending work. This set of equipment weighs about 150 kg and is divided into three phases: Parts are bulky, inconvenient for transportation and shifting, and three-phase power supply and a large flat ground are required for work. At least three people must cooperate with the operation. At the same time, the bending location is far away from the maintenance equipment, and the number of personnel exchanges is large, resulting in the expansion of the work fence, and the personnel are easy to touch live equipment by mistake or the equipment in operation is dangerous. In short, there are problems such as difficult operation and difficult to meet safety requirements when bending copper and aluminum bars.

The Chinese patent application number 201110228446.6 discloses a V-shaped bending machine, which includes a base, fixed columns on both sides of the base and top covers on the columns on both sides, and an extrusion groove is arranged on the base. A briquetting block is set, and a press is placed between the briquetting block and the top cover. A V-shaped groove is arranged on the upper side of the extrusion groove. The lower side of the pressing block is provided with a V-shaped bump corresponding to the V-shaped groove of the extrusion groove, and the two sides of the pressing block are also provided with guide grooves that match the columns on both sides. The press is a manual hydraulic jack. The hydraulic device of the invention is installed on the upper part of the bending machine, and the bending mold is set on the lower part of the bending machine. During the process of bending the mold, with the increase of the bending angle of the plate, the plate may be different from that set on the upper part. If the hydraulic device is in contact with the hydraulic device, if the force is too large, the hydraulic device and the bending machine may be damaged.

Therefore, it is necessary to develop a manpower hydraulic bending machine with simple structure, easy operation, safety, labor saving, compactness and flexibility.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a human-powered hydraulic bending machine, including a base, a frame, a hydraulic device and a bending die, characterized in that the hydraulic device is a jack, and the jack It is fixed on the base; the bottom of the bending die is connected with the ejector rod of the jack; the side of the bending die fits with the frame and slides up and down on the frame.

Preferably, the radial length of the bending die sliding up and down in the frame is 20-60 cm.

Preferably, the bending mold is in a concave shape.

Preferably, a spring is provided between the bottom of the bending mold and the base.

Preferably, there are 1 to 4 springs between the bottom of the bending mold and the base.

Preferably, the manpower hydraulic bending machine also includes a jack pressure rod placed on the outside of the frame.

Preferably, the manual hydraulic bending machine also includes a handle.

The beneficial effects produced by adopting the above-mentioned technical solution are: the utility model effectively solves the problems of three-phase power supply, multi-person operation, and large space when bending. The tool only needs one or two people to complete the work. At the same time, it does not need a power supply, which effectively guarantees the personal safety of the staff. It also solves the problem that the bending place of the electric drive bending machine is far away from the maintenance equipment, and the number of personnel exchanges is too high. It causes the expansion of the work fence, and the personnel easily touch the live equipment or the equipment in operation by mistake. In addition, the utility model has a simple structure, is easy to operate, is convenient to move and transport, and saves time and effort when bending workpieces.

Further, the radial length of the bending die sliding up and down in the frame is 20-60 cm, so as to ensure that the workpiece can be smoothly put into the bending die and be bent at a relatively large angle.

Further, the bending mold is in a concave shape, which fully provides sufficient space for the workpiece to be bent, making the workpiece easier to bend and saving labor.

Further, a spring is provided between the bottom of the bending mold and the base, and when the bending mold is squeezed and slid, the tension of the spring is used to realize the automatic recovery of the bending mold, so as to facilitate the next use.

Further, there are 1-4 springs between the bottom of the bending mold and the base to ensure that the tension of the springs is relatively high. When the bending of the workpiece is completed and the workpiece is removed, the tension of the spring can restore the bending mold to its original state .

Further, the manual hydraulic bending machine also includes a jack pressure rod, which is placed outside the frame, so as to avoid forgetting to carry the jack pressure rod or to carry the manual hydraulic bending machine and the jack pressure rod separately, which is convenient to carry and saves space.

Furthermore, the manual hydraulic bending machine also includes a handle. The bending machine is light in weight, and one person can easily move the machine. The handle is more convenient to pick up and carry, highlighting the compactness and flexibility of the tool.
