Description
Technical Field
The utility model relates to a punch press safety device belongs to punch press safety protection technical field.
Background
The punch press is a stamping type press. The design principle of the punching machine is that circular motion is converted into linear motion, a main motor drives a flywheel, a clutch drives a punching machine crankshaft to rotate, and therefore linear motion of a sliding block is achieved. The reason why the crank mechanism is used is that the lower terminal and the slider movement curve, which are easy to manufacture and capable of accurately determining the stroke, are basically used in various machining processes. Thus, this type of press is useful for punching, bending, drawing, hot forging, warm forging, cold forging, and almost all other press working.
The crankshaft of the punch press is the main rotating part of the punch press, and after the connecting rod is arranged, the crankshaft can bear the up-and-down (reciprocating) motion of the connecting rod to be changed into a circulating (rotating) motion. The crankshaft of the punching machine is an important part on the body of the punching machine, and the material of the crankshaft is made of carbon structural steel or nodular cast iron. The operation of the punch is open, only the safety grating prevents the human body from entering the range of the punch, but no measures are taken to prevent the objects in the punch from splashing outwards. If the punch presses any residual object in the pressing process, the object flies out, and the object is hit on the human body to cause fatal injury, if the object is light, the object is disabled, and if the object is heavy, the object is dead.
The application number "CN201521096944. X" is that the utility model patent of china "punch press protector", though also can play the protection usefulness, protector need additionally set up the cylinder, comes to provide the power of up-and-down motion to guard flap.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a punch press safety device who is used for protecting operating personnel safety sets up on the punch press.
In order to realize the purpose, the utility model discloses a technical scheme is:
a safety protection device for a punch comprises a rocker arm arranged on a crankshaft of the punch and a protection part connected with the rocker arm through a connecting rod; the protection part comprises a support frame fixed on the body of the punch press, guide parts arranged at two sides of the support frame and a protection plate fixing frame which moves up and down along the guide parts through a slide block and is provided with a protection plate in the middle; one end of the connecting rod is hinged with the protective plate fixing frame through a joint, and the other end of the connecting rod is hinged with the rocker arm through a joint bearing; the lower end of the guide part is also provided with a limiting block.
The utility model discloses technical scheme's further improvement lies in: the support frame is a rectangular frame and is formed by welding aluminum profiles or steel tube structures.
The utility model discloses technical scheme's further improvement lies in: the guide part is a guide shaft, a slide rail or a guide rail; the guide part is fixed on the support frame through the fixing seat by using a screw and a nut.

Drawings
Fig. 1 is a perspective view of the present invention;
fig. 2 is a front view of the present invention;
the punching machine comprises a punching machine crankshaft 1, a punching machine crankshaft 2, a rocker arm 3, a supporting frame 4, a protective plate fixing frame 5, a protective plate 6, a joint connector 7, a joint bearing 8, a shaft sleeve 9, a connecting rod 10 and a guide part.
Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses a punch press safety device who is used for protecting operating personnel safety sets up on punch press. The following are specific examples:
a punch press safety protection device comprises a rocker arm 2 arranged on a punch press crankshaft 1 and a protection part connected with the rocker arm 2 through a connecting rod 9; the rocker arm 2 is arranged on the punch crankshaft 1, and the rocker arm 2 gives acting force for the protection part to move up and down through the circular motion of the punch crankshaft 1. The protection part comprises a support frame 3 fixed on the body of the punch press, guide parts 10 arranged at two sides of the support frame 3 and a protection plate fixing frame 4 which moves up and down along the guide parts 10 through a slide block and is provided with a protection plate 5 in the middle; one end of the connecting rod 9 is connected with the protective plate fixing frame 4 through the joint 6, and the other end is connected with the rocker arm 2 through the joint bearing 7. In order to ensure the firm connection of the supporting frame 3, the supporting frame 3 is a rectangular frame, and the supporting frame 3 is formed by welding an aluminum profile or a steel pipe structure. The guide part 10 is a guide shaft, a slide rail or a guide rail, and the guide part 10 guides the guard plate fixing frame 4 to move up and down without deviation; the guide part 4 is fixed on the support frame 3 through a fixed seat by using a screw and a nut; the lower end of the guide part 10 is also provided with a limiting block; the stopper guarantees that the fixed frame of guard plate can not overstroke.
