Description

Technical Field

[0001] This utility model relates to the field of hydraulic press pressure detection technology, and in particular to a plate and frame hydraulic press pressure detection device. Background Technology

[0002] In the industrial production field, plate and frame hydraulic presses are widely used in many key processes such as metal stamping, sheet metal forming, and parts pressing due to their stable pressure output characteristics. The precise control of the pressure applied by the hydraulic press directly affects the consistency of product forming quality, the stability of the production process, and the improvement of production efficiency. Therefore, the need for real-time monitoring of the pressure applied by the hydraulic press is essential throughout the entire production process. This utility model is a pressure monitoring device for plate and frame hydraulic presses.

[0003] In existing technologies, pressure detection often adopts indirect detection methods. The pressure is transmitted through multiple structures before being collected by the sensor. This is prone to errors due to force transmission loss, structural deformation, etc. In addition, the real-time data display components of some devices are difficult to adapt to the differences in perspective such as the height and operating position of different observers, and cannot meet the observation needs in multiple scenarios, thus limiting the ease of operation.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 7 Example 1: This utility model proposes a pressure detection device for a plate and frame hydraulic press, comprising: support legs 1; four support legs 1 are provided, and a bracket 11 is installed on the upper end of the four support legs 1. A controller 12 is installed on the front end of the bracket 11. A partition 2 is fixedly installed on the bracket 11. Baffles 21 are installed on the left, right and rear sides of the partition 2. A connecting plate 22 is installed between the baffles 21 near the left and right sides of the partition 2. A seat plate 221 is installed on the connecting plate 22 by bolts. A hinge post 222 is hinged to the base plate 221. An upper card seat 223 and a lower card seat 224 are installed on the hinge post 222 by screws. The lower card seat 224 is provided with an oblong through groove. A display screen 225 is installed between the upper card seat 223 and the lower card seat 224. A card slot seat 2251 is fixed to the rear end of the display screen 225. Card slots are arrayed on the card slot seat 2251. A support frame 2211 that mates with the card slots on the card slot seat 2251 is installed on the hinge post 222. The lower end of the support 11 is provided with a hydraulic press application component 13.

[0029] In this embodiment of the utility model, four support columns 23 are fixed on the partition plate 2. A top plate 24 is fixedly installed on the upper end of the support columns 23. An actuator cylinder 241 is installed on the top plate 24. A pressure sensor 2411 is fixedly installed on the piston rod of the actuator cylinder 241. A connecting column 2412 is fixedly installed on the lower end of the pressure sensor 2411. A sliding lifting plate 242 is installed on the support columns 23. A connecting seat 2413 is installed on the lifting plate 242 by bolts. The connecting seat 2413 is fixedly connected to the lower end of the connecting column 2412. Its function is that the pressure output by the actuator cylinder 241 is transmitted to the pressure sensor 2411 through the piston rod. The pressure sensor 2411 can collect pressure data directly and in real time, avoiding the force loss error of indirect detection.

[0030] In this embodiment of the utility model, a support rod 2421 is installed on the lifting plate 242, and the support rod 2421 has an array of groove structures. A cylinder seat 243 is installed on the top plate 24, and a first hydraulic cylinder 2431 is installed on the cylinder seat 243. The piston rod of the first hydraulic cylinder 2431 is pressed into the groove structure on the support rod 2421. Its function is: when the piston rod of the first hydraulic cylinder 2431 is pressed into the groove, the position of the lifting plate 242 can be fixed by rigid limit, so as to prevent the lifting plate 242 from moving before the hydraulic cylinder 241 applies pressure, and to ensure that the initial state of detection is consistent.

[0031] In Example 2, based on Example 1, a base plate 244 is installed on the partition 2. Four rubber columns 2441 are fixed on the base plate 244. A load-bearing plate 2442 is fixed to the upper end of the four rubber columns 2441, and a top block 2444 is fixed to the lower end of the load-bearing plate 2442. A bottom block 2443 is fixed on the base plate 244. A gap is provided between the bottom block 2443 and the top block 2444. The function of this gap is that the four rubber columns 2441 serve as load-bearing plates 2442. It provides uniform support, and its elastic deformation characteristics can effectively absorb the impact load when the workpiece is under pressure, avoiding damage to the load-bearing plate 2442, the base plate 244 and the workpiece caused by rigid collision; the gap between the top block 2444 and the bottom block 2443 reserves the deformation space of the rubber column 2441. When the pressure is too great and the rubber column 2441 is compressed to the limit, the top block 2444 and the bottom block 2443 contact to form rigid support, preventing the rubber column 2441 from being damaged by excessive deformation.

[0032] In Example 3, based on Examples 1 and 2, fixing brackets 245 are fixed on both the left and right sides of the base plate 244. A top seat 246 is fixed to the upper end of the fixing bracket 245, and a sliding plate 2461 slides on the top seat 246. The lower end of the sliding plate 2461 is provided with an inclined surface. A second hydraulic cylinder 2462 is installed on the top seat 246, and the piston rod of the second hydraulic cylinder 2462 is connected to the sliding plate 2461. Two guide rods 2451 are installed on the top seat 246, and a pyramid block 2452 is fixed to the lower end of the two guide rods 2451. A round rod 2453 is fixed on the pyramid block 2452, and a contact wheel 2454 is installed on the upper end of the round rod 2453. The contact wheel 2454 contacts the lower end of the sliding plate 2461. A first spring 2455 is installed on the round rod 2453. A fixing bracket 245 is fixed with... Side plate 2456, sliding rod 2457 slides on side plate 2456, one end of sliding rod 2457 contacts pyramid block 2452, the other end of sliding rod 2457 is fixed to fixed plate 247, positioning block 2471 is fixed on fixed plate 247, and auxiliary rod 2472 is fixed on fixed plate 247. Auxiliary rod 2472 slides on side plate 2456. Second spring 2458 is installed on sliding rod 2457. Its function is: second hydraulic cylinder 2462 drives sliding plate 2461 to slide along top seat 246. Its inclined surface drives pyramid block 2452 to move up and down along guide rod 2451 through contact wheel 2454. The inclined surface of pyramid block 2452 pushes sliding rod 2457 to move laterally, so that positioning block 2471 on fixed plate 247 clamps workpiece from both sides, completing rapid positioning.

[0033] The working principle of this embodiment is as follows: First, the workpiece to be subjected to pressure is placed on the load-bearing plate 2442. The second hydraulic cylinder 2462 is activated to drive the sliding plate 2461 to slide along the top seat 246. The inclined surface at the lower end of the sliding plate 2461 drives the pyramid block 2452 to move along the guide rod 2451 through the contact wheel 2454. The pyramid block 2452 pushes the sliding rod 2457 to make the positioning block 2471 on the fixed plate 247 clamp the bottom plate 244. Then, the actuator cylinder 241 on the top plate 24 is activated, and its piston rod outputs pressure downward. Since the pressure sensor 2411 is directly fixed to the end of the piston rod of the actuator cylinder 241, it can accurately collect the pressure data output by the cylinder in real time and transmit it to the controller 12. After processing, the controller 12 displays the data on the display screen 225 in real time. At the same time, the pressure of the actuator cylinder 241 is... The pressure is transmitted to the lifting plate 242 via the pressure sensor 2411, connecting column 2412, and connecting seat 2413. The lifting plate 242 slides down along the four support columns 23 and applies pressure to the workpiece. During the pressure application process, the rubber column 2441 on the bottom plate 244 provides elastic buffer for the load-bearing plate 2442 to avoid pressure impact affecting the stability of the device. When the pressure is too high, the top block 2444 contacts the bottom block 2443 to form a rigid limit protection component. In addition, when adjusting the angle of the display screen 225, the display screen 225 can be manually moved to drive the hinge column 222 to rotate around the seat plate 221, which simultaneously drives the slot seat 2251 to rotate. When rotated to the target observation angle, the support frame 2211 is embedded in the corresponding slot of the slot seat 2251. The angle is locked by the mechanical engagement between the slot and the support frame 2211.
