The safety protection device has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.
Description
Technical field
The utility model relates to technical field of pressing machine, particularly a kind of safety device of stamping machine.
Background technology
The job step of stamping machine is at present: the first step, and the workman is placed into workpiece on frame upper surface; Second step, start the oil cylinder down maneuver, makes pressing plate decline stamped workpieces; The 3rd step, start the oil cylinder vertical motion, makes pressing plate increase and leave stamped workpieces; The 4th step, take out workpiece, then again by first step circulation.The workman often repeats above-mentioned cycling, and the security incident that pressing plate weighs the workman wounded so just easily often occurs for not only fatigue but also dullness.Therefore, how to guarantee pressman's handling safety, avoid the problem such as secure ram accident to become the focus of research in the industry.
For effectively solving existing issue, many significant explorations have been done in the industry.Such as by pliers, carrying out holding workpiece, the event that can avoid the workman to weigh wounded because of maloperation like this, but pliers is difficult to clamp, volume is large, the workpiece of Heavy Weight, has so just limited the scope of application of pliers.In addition, equipment is when maintenance, and still there is the hidden danger of secure ram accident in pressing plate.
Therefore be necessary existing stamping machine structure is carried out to technological innovation further.
The utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and the safety device of stamping machine a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
The safety device of a kind of stamping machine described in the utility model, comprise support, guide post, upper frame, oil cylinder and pressing plate, described support is fixedly connected by fixed mount and upper frame, described oil cylinder is fixedly installed on upper frame, the expansion link of described oil cylinder is fixedly connected through through hole and the pressing plate of upper frame, described guide post one end is fixed on the bottom surface of upper frame, the described guide post other end is fixedly connected through pressing plate and frame upper surface, the left and right sides of described frame upper surface is symmetrically arranged with fixed block, described fixed block is fixedly connected with cylinder, the expansion link of described cylinder is fixedly connected with push rod, described push rod height is less than the maximum rising height of pressing plate, the inlet, outlet of cylinder is connected with source of the gas, and the work of cylinder is controlled by electric control gear.
Further, described push rod upper surface is provided with buffer stopper.
Further, described push rod lower surface is provided with several rollers.
After adopting said structure, the utility model beneficial effect is: the safety device of a kind of stamping machine described in the utility model, comprise support, guide post, upper frame, oil cylinder and pressing plate, described support is fixedly connected by fixed mount and upper frame, described oil cylinder is fixedly installed on upper frame, the expansion link of described oil cylinder is fixedly connected through through hole and the pressing plate of upper frame, described guide post one end is fixed on the bottom surface of upper frame, the described guide post other end is fixedly connected through pressing plate and frame upper surface, the left and right sides of described frame upper surface is symmetrically arranged with fixed block, described fixed block is fixedly connected with cylinder, the expansion link of described cylinder is fixedly connected with push rod, described push rod height is less than the maximum rising height of pressing plate, the inlet, outlet of cylinder is connected with source of the gas, and the work of cylinder is controlled by electric control gear.While using the utility model, by push rod is set, prevent that pressing plate from descending, greatly improved the security performance of stamping machine, thereby avoided pressing plate decline to weigh personnel's security incident wounded.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
