Abstract
The utility model relates to a hydraulic press protection device belongs to hydraulic press technical field, include: the hydraulic press comprises a travel switch, a push rod, an air cylinder and a support, and is characterized in that the support is fixedly connected to a bottom plate of the hydraulic press, the air cylinder is fixedly connected to the support, the push rod is fixedly connected to a push rod of the air cylinder, and the travel switch is fixedly arranged at the upper end of the push rod; when the cylinder pushes out the ejector rod through the push rod, the ejector rod is positioned on the right side between the middle plate and the bottom plate of the hydraulic machine; the installation is convenient, the sudden situation that the middle plate suddenly slips off during the operation of the hydraulic press can be effectively dealt with, and the production safety of workers is ensured.
Description
Technical Field
The utility model relates to a hydraulic press protection device belongs to hydraulic press technical field.
Background
The hydraulic press can be used for forging and forming, straightening, press fitting, packing, pressing blocks, pressing plates and the like. Compared with the traditional stamping process, the hydroforming process has obvious technical and economic advantages in the aspects of reducing weight, reducing the number of parts and dies, improving rigidity and strength, reducing production cost and the like, and is increasingly applied in the industrial field. In the hydraulic press working process, the staff need carry out the mould and install the debugging, puts and gets a series of operations such as raw materials, semi-manufactured goods, and in operation, in case emergency appears, staff's misoperation or hydraulic press work are unusual, and the medium plate of hydraulic press slides down suddenly, if do not have protection device or other safeguard measure, can cause serious injury to the staff very probably, have certain potential safety hazard. In the prior art, like CN201520346832.9, although a limit block is provided for limiting protection, in an emergency, if the hydraulic press continues to be pressed down, the limit block is likely to be damaged due to failure of bearing the pressure of the hydraulic press, so that the whole protection device is damaged, and the safety accident is caused due to failure of protecting the working personnel.
Disclosure of Invention
The utility model aims at providing a hydraulic press protection device, its simple structure, simple to operate can effectively deal with the emergency of the sudden landing of hydraulic press during operation medium plate, ensures staff's production safety.
In order to solve the technical problem, the utility model discloses a technical scheme does:
a hydraulic machine protection device, comprising: the hydraulic press comprises a travel switch, a push rod, an air cylinder and a support, and is characterized in that the support is fixedly connected to a bottom plate of the hydraulic press, the air cylinder is fixedly connected to the support, the push rod is fixedly connected to a push rod of the air cylinder, and the travel switch is fixedly arranged at the upper end of the push rod; when the cylinder pushes out the ejector rod through the push rod, the ejector rod is positioned on the right side between the middle plate and the bottom plate of the hydraulic press.
Preferably, the top rod is perpendicular to the middle plate and the bottom plate.
Preferably, the cross section of the ejector rod is square or rectangular.
Has the advantages that:
the utility model has simple structure and convenient installation, if the hydraulic press has emergency, the middle plate slides down suddenly, and the middle plate can be propped by the ejector rod to prevent further sliding down, thereby ensuring the production safety of workers; and travel switch sets up in the upper end of ejector pin, and during the medium plate landing, can touch travel switch earlier, travel switch can cut off the power of motor immediately, and the oil pump is out of work, prevents to increase the pressure that the medium plate pushed down, further improves the security, uses vertical ejector pin, and the atress effect is better, and compressive capacity is stronger.
Drawings
The present invention is further explained by using the drawings, but the embodiments in the drawings do not constitute any limitation to the present invention, and for those skilled in the art, other drawings can be obtained according to the following drawings without any inventive work.
FIG. 1 is a view showing a normal operation of the present invention;
fig. 2 is a schematic view of the present invention in an emergency.
In the figure: 1. the device comprises a hydraulic machine, 2, a travel switch, 3, a mandril, 4, a cylinder, 5, a bracket, 6, a middle plate, 7, a bottom plate, 8 and a push rod.
Detailed Description
The invention will be further described with reference to the following examples.
As shown in fig. 1, a hydraulic machine protection device includes: the hydraulic press is characterized in that the support 5 is fixedly connected to a bottom plate 7 of the hydraulic press 1, the cylinder 4 is fixedly connected to the support 5, the ejector rod 3 is fixedly connected to a push rod 8 of the cylinder 4, and the travel switch 2 is fixedly mounted at the upper end of the ejector rod 3; when the cylinder 4 pushes out the ejector rod 3 through the push rod 8, the ejector rod 3 is located on the right side between the middle plate 6 and the bottom plate 7 of the hydraulic press 1, the touch position of the travel switch 2 is higher than the top of the ejector rod 3, when the middle plate suddenly slides downwards, the travel switch is triggered firstly, and then the middle plate is propped by the ejector rod.
The top rod 3 is perpendicular to the middle plate 6 and the bottom plate 7.
The cross section of the ejector rod 3 is square or rectangular.
The working principle is as follows: when the middle plate rises to the top, the safety device instructs the cylinder ejector rod to push out through the travel switch at the top of the hydraulic machine, the ejector rod extends into the middle plate, the ejector rod can be retracted by pressing the working switch cylinder, and the operation is circulated; if emergency appears, the medium plate suddenly slides down, and the medium plate can touch the travel switch first. The travel switch can immediately cut off the power supply of the motor, the oil pump does not work, then the middle plate is propped by the ejector rod and does not slide down, and the production safety of workers is ensured.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
