Description
Technical Field
The utility model relates to the technical field of safety brakes, in particular to a pneumatic safety brake of an electronic control screw press.
Technical Field
The electric control screw press is a forging and pressing forming device which takes a screw rod and a nut as a transmission structure and converts forward and reverse motion of a flywheel into up and down reciprocating motion of a sliding block through screw transmission. When the electric control screw press works, the motor generates electricity to enable the flywheel to obtain energy through accelerated rotation, so that the screw rod and the nut are driven to push the sliding block to move downwards. When the sliding block is contacted with a workpiece, the flywheel decelerates until the sliding block stops, the stored rotary kinetic energy is converted into impact energy, the workpiece is subjected to impact forming through the sliding block, and after the impact forming is finished, the motor generates electricity again to enable the flywheel to run reversely, drive the sliding block to move upwards and return to the initial position, so that the electric control screw press finishes one period of work.
The electric control screw press is used for carrying out impact forming on a workpiece through the up-and-down operation of the sliding block, the formed workpiece needs to be manually taken out of a press die, at the moment, the screw press is suddenly stopped, the possibility that the sliding block is out of control and slides downwards exists in the process, and the personal safety of field operators is threatened, so that the pneumatic safety brake of the electric control screw press is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a pneumatic safety brake of an electric control screw press, which aims to solve the problems in the technical background.
In order to achieve the purpose, the utility model provides the following technical scheme: an electronic control screw press pneumatic safety brake comprises a support column, a connecting plate and a cylinder; the supporting device is connected with the connecting plate in a hinge mode, the cylinder part is connected with the connecting plate through a cylinder rod, and the connecting plate and the cylinder part are simultaneously fixed on one side of the body of the screw press.
According to the pneumatic safety brake of the electric control screw press, the spring is arranged on the safety brake support.
The pneumatic safety brake of the electric control screw press is characterized in that the cylinder part is connected with the electromagnetic directional valve through the two air pipes, and the electromagnetic directional valve is connected with the large cylinder at the upper part of the screw press through the main air pipe.
The utility model has the beneficial effects that: compared with the prior art, the pneumatic safety brake of the electric control screw press can realize that the support column of the pneumatic safety brake is automatically closed under the action of the electromagnetic directional valve after the screw press slide block moves upwards, the support slide block prevents the support slide block from sliding down under the abnormal working condition to accidentally injure field operators, the pneumatic safety brake is automatically opened when the press slide block normally slides down, the normal work of the press slide block is ensured, the personal safety of workers is protected, the manpower is saved, and the practicability is strong.
Drawings
FIG. 1 is a schematic view of the pneumatic safety brake of the electrically controlled screw press according to the present invention.
The meanings of the symbols in the figures: the device comprises a press body, a spring, a support column, a connecting plate, a cylinder rod, a press body, a cylinder, a total air pipe and an electromagnetic directional valve, wherein the press body comprises 1-the spring, 2-the support column, 3-the connecting plate, 4-the cylinder rod, 5-the press body, 6-the cylinder, 7-the total air pipe and 8-the electromagnetic directional valve.
Detailed Description
The present invention is described in further detail below, but is not to be construed as being limited thereto
Example 1
Referring to fig. 1, the present invention provides a technical solution: an electric control screw press pneumatic safety brake. Comprises a support column 2, a connecting plate 3 and a cylinder part 6; wherein the support 2 is connected with the connecting plate 3 by means of a hinge, and the cylinder part 6 is connected with the connecting plate 3 by means of a cylinder rod 4.
The connecting plate 3 and the cylinder part 6 are simultaneously fixed on one side of the body of the screw press, so that the integrity of the safety brake and the matching performance of the work of the screw press are achieved. A spring 1 is arranged above the supporting column 2 to reduce impact force caused by sliding of a sliding block of the electric control screw press under abnormal working conditions. The cylinder part 6 is connected with the electromagnetic directional valve 8 through two air pipes, and the electromagnetic directional valve 8 drives the cylinder rod to stretch and retract by changing the flowing direction of gas in the cylinder so as to further drive the connecting plate 3 and the support column 2 to be closed or opened. The electromagnetic directional valve 8 is connected with the upper cylinder of the screw press through a main air pipe 7 to provide air for the cylinder part of the safety brake.
The working process of the pneumatic safety brake of the electric control screw press comprises the following steps: after the sliding block of the electric control screw press rises, the pneumatic safety brake electromagnetic directional valve 8 provides gas for the cylinder through the main air pipe 7, the gas in the cylinder flows to drive the cylinder rod to extend out, the connecting plate 3 is pulled to drive the supporting column 2 to move to the lower part of the sliding block, and the sliding block is supported to prevent the sliding block from sliding downwards, so that the safety brake is in a closed state; when the slide block is about to normally work downwards, the electromagnetic directional valve 8 changes the gas flowing direction in the cylinder, so that the cylinder rod retracts to drive the connecting plate 3 and the supporting column 2 which are connected with the cylinder rod, the supporting column 2 moves away, and the slide block normally falls, which is the opening state of the safety brake, and is a work period of the pneumatic safety brake.
Although the utility model has been described in detail hereinabove with respect to a general description and specific embodiments thereof, it will be apparent to those skilled in the art that modifications and improvements can be made thereto based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
