Description

Technical Field

[0001] This utility model belongs to the field of hydraulic press technology, and in particular relates to a self-cleaning hydraulic press. Background Technology

[0002] In many industrial production fields, such as leather processing, hydraulic presses are widely used in stamping, blanking, and other processes due to their powerful pressure output capabilities. In these processes, the hydraulic press applies enormous pressure through a pressure plate, causing a die to blank the material being processed, thereby obtaining the desired part shape.

[0003] However, existing hydraulic presses have a significant problem in practical use: after the blanking operation is completed, debris and other foreign matter easily adhere to the surface of the press plate. Once these debris adheres to the plate surface, it will seriously affect the quality of the product during the next blanking round. For example, it can cause defects such as indentations and scratches on the surface of the blanked product, reduce the dimensional accuracy and surface quality of the product, increase the scrap rate, thereby increasing production costs, reducing production efficiency, and affecting the economic benefits of the enterprise.

[0004] To address this issue, some companies are currently attempting to manually clean the surface of the pressure plates periodically. However, this method is not only labor-intensive and time-consuming, but also requires machine downtime, impacting processing efficiency. Furthermore, manual cleaning is rarely thorough, leaving some debris residue that fails to fundamentally resolve the problem of debris adhesion affecting product quality. Other companies have tried installing simple air-blowing devices on hydraulic presses, but because the blowing position and force are difficult to control precisely, this not only fails to effectively remove all adhered debris but may also blow debris onto other parts of the worktable, causing secondary pollution and affecting the normal operation of surrounding equipment.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, according to Figure 1-6 As shown, the device includes a base 100, within which a transport channel 110 is provided, running through the entire base 100. A conveying device 120 is provided within the transport channel 110, capable of cyclically transporting multiple blade templates 130. A hydraulic device 200 and a blade holder plate moving and cleaning device are provided on the base 100. The conveying device 120 passes through the hydraulic device 200. The blade holder plate moving and cleaning device includes a first moving device 310 and a second moving device 320 located at the front and rear ends of the hydraulic device 200. The base 100 also has an extending cleaning... The cleaning channel 330 is also located between the first moving device 310 and the second moving device 320. The cleaning channel 330 is equipped with a cleaning component 340. The first moving device 310 can place a blade support plate on the blade template 130 with the material placed on it. Under the action of the conveying device 120, it is hydraulically cut by the hydraulic device 200 and then transported out. The second moving device 320 can place the blade support plate into the cleaning channel 330 on the side and transport it to the cleaning component 340 for cleaning. After the blade support plate is cleaned, it continues to be transported to the first moving device 310 for use.

[0030] The specific working steps are as follows: The conveying device 120 can cyclically transport multiple die templates 130. The die template 130 closest to the hydraulic device 200, when it is about to enter the hydraulic device 200, the first moving device 310 can place a die support plate on the die template 130 with material placed on it. Under the action of the conveying device 120, it is transported out after hydraulic die cutting by the hydraulic device 200. The second moving device 320 can take the above-mentioned die support plate and place it into the cleaning channel 330 on the side. The cleaning channel 330 transports the above-mentioned die support plate to the cleaning component 340 for cleaning. After cleaning, it is transported to the first moving device 310 for use. Subsequently, the first moving device 310 places the cleaned die support plate on the next die template 130 with material placed on it, and so on.

[0031] Furthermore, by installing a blade rest plate and coordinating it with a moving cleaning device, the surface of the blade rest plate can be scraped and cleaned after the blanking operation. This removes residual debris generated during blanking, effectively preventing surface indentations, scratches, and other defects in the next round of blanking caused by debris residue. This significantly improves the dimensional accuracy and surface quality of the products, reduces the scrap rate, and ensures the stability and reliability of product quality. Simultaneously, the entire cleaning process is automated, requiring no manual intervention, saving manpower, and eliminating the need for machine downtime for cleaning, thus improving processing efficiency.

[0032] In another embodiment of this utility model, such as Figure 2 and 6 As shown, the cleaning component 340 is located between the first moving device 310 and the second moving device 320. The cleaning component 340 includes an upper brush 341 and a lower brush 342. The blade rest plate can pass between the upper brush 341 and the lower brush 342, and the blade rest plate is cleaned of debris on its surface as it passes between the upper brush 341 and the lower brush 342. Both sides of the upper brush 341 and the lower brush 342 are connected to the base 100. The cleaning channel 330 is composed of multiple belts, which are driven by a motor and a rotating roller, thereby driving the blade rest plate to move. The multiple belts also pass between the upper brush 341 and the lower brush 342. During the process of the blade rest plate passing between the upper brush 341 and the lower brush 342, the upper brush 341 and the lower brush 342 clean both surfaces of the blade rest plate.

[0033] Furthermore, the front end of the cleaning component 340 is also provided with a cover plate, which is placed on top of the cleaning channel 330. The cover plate acts as a guide, allowing the blade pad to pass smoothly between the upper brush 341 and the lower brush 342.

[0034] Furthermore, the cleaning component 340 has a placement platform 350 at its bottom, and a collection bucket 360 is provided on the placement platform 350 for collecting debris during cleaning.

[0035] In another embodiment of this utility model, such as Figure 1 and 4 As shown, the first moving device 310 includes a first clamping assembly and a first driving device; the first driving device can drive the first clamping assembly to clamp the blade support plate and transport it to the blade template 130 on which the material is placed. The first clamping assembly includes two first clamping claws 311; the first driving device includes a first lateral driving assembly 312 and a first clamping driving assembly 313. The first clamping driving assembly 313 includes a first connecting plate 3131. The two ends of the first connecting plate 3131 are respectively provided with first clamping cylinders 3132. Each first clamping cylinder 3132 is connected to a first clamping claw 311. The two first clamping cylinders 3132 can control the two first clamping claws 311 to retract inward and expand outward. The first lateral driving assembly 312 is connected to the first connecting plate 3131 and can drive the first connecting plate 3131 to move laterally, thereby clamping the blade support plate and moving it laterally from the cleaning channel 330 to the blade template 130 on which the material is placed.

[0036] Specifically, the first transverse drive assembly 312 can be a combination of a motor and a lead screw, a combination of a motor and a synchronous belt, a combination of a motor and a rack and pinion, an electric push rod, or a cylinder, etc. As a preferred option, this patent selects a combination of a motor, a synchronous belt, and a slider to achieve linear motion, which is fast, has a long stroke, low noise, and low cost.

[0037] Furthermore, the first transverse drive assembly 312 drives the first connecting plate 3131 to move directly. The first connecting plate 3131 is provided with first clamping cylinders 3132 at both ends. Each clamping cylinder is provided with a first clamping claw 311. The two first clamping cylinders 3132 can extend relative to each other to achieve clamping, or they can retract to reach the contact clamping state, thereby realizing the transportation of the blade rest plate.

[0038] In another embodiment of this utility model, according to Figure 1 and 5As shown, the second moving device 320 includes a second clamping assembly and a second driving device; the second clamping assembly can clamp the blade pillow plate and flip it, and the second driving device can drive the second clamping assembly to move the flipped blade pillow plate into the cleaning channel 330. The second clamping assembly includes two rotary cylinders 321; each rotary cylinder 321 is provided with a second clamping claw 322. The second driving device includes a second transverse driving assembly 323, a second longitudinal driving assembly 324, and a second clamping driving assembly 325. The second clamping driving assembly 325 includes a second connecting plate 3251. The two ends of the second connecting plate 3251 are respectively provided with second clamping cylinders 3252. Each second clamping cylinder 3252 is connected to a corresponding rotary cylinder 321. The two second clamping cylinders 3252 can control the two rotary cylinders 321 to retract inward and expand outward, thereby controlling the two second clamping claws 322 to clamp the blade support plate. The second transverse driving assembly 323 is disposed on the second longitudinal driving assembly 324, and the second connecting plate 3251 is disposed on the second transverse driving assembly 323. The second transverse driving assembly 323 and the second longitudinal driving assembly 324 can drive the two second clamping claws 322 to clamp the blade support plate and place it from the conveying device 120 into the cleaning channel 330 on the side.

[0039] Specifically, the second lateral drive assembly 323 and the second longitudinal drive assembly 324 can be a combination of a motor and a lead screw, a combination of a motor and a synchronous belt, a combination of a motor and a rack and pinion, an electric push rod, or a cylinder, etc. Preferably, this patent selects a combination of a motor, a synchronous belt, and a slider to achieve linear motion, which is fast, has a long stroke, low noise, and low cost. In this patent, the second longitudinal drive assembly 324 consists of two longitudinal slide rods, with the second lateral drive assembly 323 located between the two longitudinal slide rods.

[0040] Furthermore, the second transverse drive assembly 323 and the second longitudinal drive assembly 324 first drive the two second clamping claws 322 to approach the blade rest plate. Under the action of the second clamping cylinder 3252, they achieve tight clamping. Then, under the action of the rotary cylinder 321, the blade rest plate is rotated. Finally, under the drive of the second transverse drive assembly 323 and the second longitudinal drive assembly 324, the blade rest plate is placed on the cleaning channel 330.

[0041] Furthermore, the blade support plate is rotated and then placed into the cleaning component 340 for cleaning, and then placed into the blade template 130 for use. This means that each blade support plate is cleaned twice, ensuring the cleanliness as much as possible, reducing the possibility of small amounts of debris residue, resulting in better dimensional accuracy and surface quality of the product, and increasing the yield rate.

[0042] In another embodiment of this utility model, according to Figure 1-3As shown, the conveyor device 120 is a chain-driven circulating conveyor belt. A cutter template 130 is provided on the conveyor device 120. The cutter template 130 is circulated and driven by the transmission chain in the conveyor device 120, and always remains horizontally upward. Each cutter template 130 has a cutter die with the cutting edge facing upward. Opposite ends of the cutter template 130 are fixedly connected to the chain-driven circulating conveyor belt, and the other opposite ends are provided with pulleys 131. A support plate is provided in the transport channel 110, and the pulleys 131 can slide and support on the support plate. Specifically, the chains at both ends of the circulating conveyor belt are of the same length but are staggered at both ends; that is, at one end, one chain is longer and the other shorter, and vice versa at the other end. This design ensures that the cutter template 130 always remains horizontally upward at bends.

[0043] The circulating conveyor belt includes chains at both ends, drive rollers, and a motor. The motor drives the drive rollers to rotate, and the chains are wound around the drive rollers. The two diagonally opposite ends of the die template 130 are connected to the chain, so that the die template 130 can always face upwards, i.e., the side with the die is always facing upwards, preventing the die from falling. The other two opposite ends are equipped with pulleys 131. During parallel transport, the pulleys 131 can slide and support the device on the support plate. When turning at an angle, the two ends with pulleys 131 leave the support plate and turn while suspended in the air.

[0044] In another embodiment of this utility model, according to Figure 1 and 2 As shown, the hydraulic device 200 is composed of a double-headed hydraulic cylinder. Many existing hydraulic devices 200 are single-headed. When a single hydraulic head drives the pressure plate to impact, it is easy to experience uneven force, and some parts may not be cut off. The double hydraulic head avoids this problem well, making the pressure more uniform during stamping and cutting the material cleanly and crisply.

[0045] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
