Abstract
A punching mechanism of a numerical control press comprises a cylinder body, wherein the cylinder body is provided with a groove with a downward opening, and the opening of the groove is covered by an end cover and is in sealing connection with the end cover; a piston is connected in the groove in a sealing mode, the piston divides the groove into an upper cavity and a lower cavity, the upper cavity is communicated with a first hydraulic oil pipeline, the lower cavity is communicated with a second hydraulic oil pipeline, a piston rod is fixedly connected with the piston and stretches out of the end cover, the piston rod is in sealing connection with the end cover, and a punching block is fixedly connected with the end, stretching out of the end cover, of the piston rod. The punching mechanism of the numerical control press can provide great punching force and meet requirements of macropore machining of plates with moderate thicknesses for punching force, and is simple in structure, convenient to operate and steady in operation.
Description
Technical field
The utility model relates to numerical control press, is specifically related to the workbench of numerical control press equipment.
Background technology
Numerical control press, it is a kind of automated machine tool that program control system is housed, this control system can logically be processed has control coding or other symbolic instruction regulated procedures, and by its decoding, thereby make punch press action processing parts, with respect to common punch press, its working (machining) efficiency is high, and labour intensity is lower.In prior art, numerical control press is applied to the processing of small size thin plate mostly, and for the macropore requirement of cut deal, especially the macropore requirement of the cut deal in steel structure industry, because the requirement of its oil cylinder and stamping press is higher, therefore, use general oil cylinder can not reach the requirement of stamping press, conventionally can only adopt other machine cut processing modes to process, cause inefficiency, and increased cost.
Utility model content
The utility model, for above-mentioned shortcoming of the prior art, provides a kind of numerical control press punching mechanism rational in infrastructure, and it can provide larger stamping press, meets the stamping press requirement of cut deal macropore processing, and simple in structure, easy to operate, operate steadily.
The technical scheme that the utility model adopts is as follows:
Numerical control press punching mechanism, comprises cylinder body, and cylinder body has the groove that Open Side Down, and the opening of described groove is covered by end cap, and is tightly connected between the two; In described groove, be sealedly connected with piston, described groove is divided into upper and lower two chambeies by piston, and described epicoele is communicated with hydraulic oil pipeline one, described cavity of resorption is communicated with hydraulic oil pipeline two, piston is fixedly connected with piston rod, and piston rod stretches out end cap, and is tightly connected between piston rod and end cap; The rod end head that piston rod stretches out end cap is connected with pressing block.
Its further technical scheme is:
Collision block is equipped with by feather key in the side of described pressing block, and feather key and switch frame are slidably connected on vertical, and switch frame is provided with the travel switch coordinating with collision block, and switch frame is fixed on end cap.
Technique effect of the present utility model:
The utility model adopts homemade large cylinder diameter oil cylinder, larger stamping press can be provided, meet the stamping press requirement of cut deal macropore processing, in engineering practice, the stamping press of punching mechanism described in the utility model can reach 80T, can process at the thick steel plate of 25mm the hole of φ 25mm, its not only simple in structure, operate steadily reliable, and simple operation, automaticity is high, is applicable to processing in enormous quantities.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
Wherein: 1, cylinder body; 2, end cap; 3, piston; 4, piston rod; 5, pressing block; 6, hydraulic oil pipeline one; 7, hydraulic oil pipeline two; 8, feather key; 9, collision block; 10, switch frame; 11, travel switch; 12, round nut.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 1, Fig. 2, the utility model comprises cylinder body 1, and cylinder body 1 has the groove that Open Side Down, and the opening of described groove is covered by end cap 2, and passes through sealing ring radial seal between the two; In described groove, be sealedly connected with piston 3 by sealing ring, described groove is divided into upper and lower two chambeies by piston 3, described epicoele is communicated with hydraulic oil pipeline 1, described cavity of resorption is communicated with hydraulic oil pipeline 27, piston 3 is fixedly connected with piston rod 4, piston 3 is fixed on piston rod 4 by two round nuts 12, and piston rod 4 stretches out end cap 2, and passes through sealing ring radial seal between piston rod 4 and end cap 2; The rod end head that piston rod 4 stretches out end cap 2 is connected with pressing block 5; Collision block 9 is equipped with by feather key 8 in the side of pressing block 5, feather key 8 is slidably connected on vertical with switch frame 10, particularly, on switch frame 10, have vertical long groove, feather key 8 slides in described vertical long groove, switch frame 10 is provided with upper and lower two travel switches 11 that coordinate with collision block 9, and switch frame 10 is fixed on end cap 2.
On punch press after locating clip clamping of workpieces, hydraulic oil pipeline one 6 oil-feeds, hydraulic oil pipeline 27 oil returns, promote piston 3 descending, piston 3 drives pressing block 5 descending, and completes punching press, otherwise, hydraulic oil pipeline one 6 oil returns, hydraulic oil pipeline 27 oil-feeds, promote piston 3 up, make thus pressing block 5 repositions, in the up and descending process of pressing block, the upper and lower stroke and the position that coordinate to limit pressing block 5 by upper and lower two travel switches 11 with collision block 9.Punching mechanism described in the utility model adopts the large cylinder diameter oil cylinder of self-control, can meet the stamping press requirement of cut deal macropore processing.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
