Abstract
The invention relates to a bidirectional punching press with constantly changing mold clamping force, belonging to the technical field of hydraulic press. The bidirectional punching press with constantly changing mold clamping force is a four-column press characterized in that an upper crossbeam, a slider block, a lower crossbeam, a main oil cylinder and side pressing cylinders are arranged on the press; the main oil cylinder is arranged in the upper crossbeam; and the left and right pressing cylinders are oppositely arranged on the lower crossbeam. The bidirectional punching press is simple in structure, convenient in operation and low in cost and can satisfy special technical requirements. The bidirectional punching press is capable of punching bidirectionally and is high in production efficiency and wide in application range, and the pressed piece has good quality.
Description
Technical field
The invention belongs to the hydraulic press technical field, particularly relate to the bidirectional punching press of constantly changing mold clamping force.
Background technology
At present, continuous development along with China's industry, traditional unidirectional Sheet Metal Forming Technology has not satisfied the manufacturing demand of some special workpieces, promptly enable to produce this part, but operating efficiency is also lower, and cost is also very high, the press poor product quality, can not satisfy the manufacturing production and processing needs demand of modern product, also increase working strength of workers.
Summary of the invention
The present invention provides a kind of bidirectional punching press of constantly changing mold clamping force for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide and a kind ofly have simple in structurely, easy to operate, with low cost, can satisfy the special workpiece technological requirement, bidirectional punching, the casting die quality is good, production efficiency height, the bidirectional punching press of the constantly changing mold clamping force of characteristics such as applied widely.
The present invention is the bidirectional punching press of constantly changing mold clamping force, and the big more mold clamping force of side pressure cylinder pressure is big more, and this press can be finished bidirectional punching.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of bidirectional punching press of constantly changing mold clamping force, be the four-column type press, be characterized in: press has entablature, slide block, sill, master cylinder and side pressure cylinder, and master cylinder is arranged in the entablature, the left and right sides cylinder pressure is arranged on the sill, and the left and right sides cylinder pressure assembles layout relatively.
The present invention can also adopt following technical scheme:
The bidirectional punching press of described constantly changing mold clamping force is characterized in: the left and right sides cylinder pressure is fixed in sill, and the left and right sides cylinder pressure is a hydraulic jack.
The bidirectional punching press of described constantly changing mold clamping force is characterized in: the left and right sides cylinder pressure outside press columns by bolting in sill, the cylinder bar assembles relatively.
Advantage and good effect that the present invention has are:
The bidirectional punching press of constantly changing mold clamping force has been owing to adopted brand-new technology scheme of the present invention, compared with prior art, the bidirectional punching press of constantly changing mold clamping force, the big more mold clamping force of side pressure cylinder pressure is big more, but this press high efficiency is finished bidirectional punching.The present invention has simple in structure, and is easy to operate, with low cost, can satisfy the special workpiece technological requirement, bidirectional punching, and the casting die quality is good, production efficiency height, advantage such as applied widely.
Description of drawings
Fig. 1 is an assembly structure schematic diagram of the present invention.
Among the figure, 1, entablature, 2, master cylinder, 3, slide block, 4, the side pressure cylinder, 5, sill, 6, post.
The specific embodiment
For further understanding technology contents of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1.
Embodiment 1
A kind of bidirectional punching press of constantly changing mold clamping force is the four-column type press, and press has entablature 1, slide block 3, sill 5, master cylinder 2 and side pressure cylinder 4, and master cylinder 2 is arranged in the entablature 1.Left and right sides cylinder pressure 4 is arranged on the sill, and the left and right sides cylinder pressure is a hydraulic jack.The left and right sides cylinder pressure assembles layout relatively, outside press columns 6 by bolting in sill, the cylinder bar assembles relatively.
The workflow of the bidirectional punching press of this constantly changing mold clamping force is as follows:
Slide block falls soon → slide block fall slowly stop → slide block pressurization time-delay → left and right sides cylinder pressure advances → moulding → left and right sides cylinder pressure pressure release → slide block pressure release → slide block backhaul of advancing of slide block matched moulds → left and right sides cylinder pressure.
