Description

Technical Field

[0001] This application relates to the field of hydraulic press technology, and in particular to a hydraulic press slide structure. Background Technology

[0002] A hydraulic press is a machine that uses liquid as the working medium and utilizes Pascal's principle to transfer energy to achieve various processes. It is widely used in metal processing, plastic molding, rubber pressing and powder metallurgy.

[0003] When a hydraulic press finishes processing a workpiece, the operator needs to remove the finished workpiece from the processing end of the hydraulic press and place the workpiece to be processed on the processing end of the hydraulic press for further processing. This reduces the processing efficiency of the workpiece, prolongs the processing cycle of the workpiece, and thus increases the processing cost of the workpiece. Utility Model Content

[0004] To improve the processing cycle of workpieces, this application provides a hydraulic press slide structure.

[0005] This application provides a hydraulic press slide structure, which adopts the following technical solution: A hydraulic press slide structure includes a feeding device and a base on the hydraulic press. The surface of the base is provided with a processing station facing the processing end of the hydraulic press. The feeding device includes at least two worktables, which are slidably connected to the surface of the base. The worktable surfaces are for placing workpieces. The worktables are slidable toward the processing station. When one of the worktables is located at the processing station, the workpiece on the worktable faces the processing end of the hydraulic press.

[0006] By adopting the above technical solution, both worktables are slidably connected to the base surface. When one workpiece is placed on one of the worktables, the worktable with the workpiece slides towards the processing station. The worktable is located at the processing station, and the hydraulic press processing end faces the workpiece to be processed at the processing station. While the hydraulic press processing end processes the workpiece to be processed at the processing station, other workpieces to be processed are placed on the other worktable. When the workpiece at the processing station is processed, the worktable with the processed workpiece slides away from the processing station, and the worktable with the unprocessed workpiece slides towards the processing station. The worktable with the unprocessed workpiece faces the processing station, and the hydraulic press processing end processes the workpiece to be processed at the processing station. At the same time, the processed workpiece on the other worktable is removed and an unprocessed workpiece is placed. The above actions are repeated to achieve synchronous loading and unloading of workpieces, improve the processing efficiency of workpieces, shorten the processing cycle of workpieces, and thus reduce the processing cost of workpieces.

[0007] Optionally, the feeding device further includes at least two push-pull assemblies, each corresponding to a worktable. Each push-pull assembly includes a push-pull cylinder and a push-pull block. The push-pull cylinder is connected to the base surface, and the piston rod axis of the push-pull cylinder is parallel to the sliding direction of the worktable. The push-pull block is connected to the surface of the worktable away from the processing station, and the end face of the piston rod of the push-pull cylinder is connected to the surface of the push-pull block. When the piston rod of the push-pull cylinder extends, the worktable moves away from the processing station; when the piston rod of the push-pull cylinder retracts, the worktable is located at the processing station.

[0008] By adopting the above technical solution, when the workpiece to be processed is placed on one of the worktables, the piston rod of the push-pull cylinder retracts, the worktable is located on the processing station, the hydraulic press processing end processes and completes the workpiece on the processing station, the piston rod of the push-pull cylinder extends, the worktable moves away from the processing station, and at the same time the other worktable is located on the processing station, the operator removes the processed workpiece from the worktable away from the processing station and places the unprocessed workpiece, realizing precise control of the sliding distance of the two worktables on the base surface, thereby improving the processing quality of the workpiece.

[0009] Optionally, the push-pull assembly further includes multiple support plates, with the ends of the multiple support plates being connected at intervals to the surface of the base. When the worktable is away from the processing station, the end faces of the support plates that are flush with the base abut against the bottom surface of the worktable to form support.

[0010] By adopting the above technical solution, multiple support plates are connected at intervals to the base surface. When the worktable slides away from the processing station, the end face of the support plate flush with the base abuts against the bottom surface of the worktable to form support, thereby improving the stability of the worktable's sliding. At the same time, the sliding area of ​​the worktable on the base surface does not need to be increased by expanding the volume of the base, reducing the material input of the base and thus reducing the investment cost of the feeding device.

[0011] Optionally, the feeding device further includes multiple sliding plates, which are connected at intervals to the base surface. The length direction of the sliding plates is parallel to the sliding direction of the worktable. The worktable surface is provided with a slide for the sliding plates to slide, and the thickness of the sliding plates is greater than the depth of the slide.

[0012] By adopting the above technical solution, when the worktable slides on the surface of the base, it drives the slide plate to slide on the inner wall of the slide rail, making it less likely for the worktable to deviate during the sliding process, thereby improving the stability of the worktable sliding; at the same time, the thickness of the slide plate is greater than the depth of the slide rail, so that the inner wall of the slide rail and the surface of the slide plate slide in contact, reducing the wear between the worktable and the base, thereby extending the service life of the feeding device.

[0013] Optionally, the slide plate is made of copper.

[0014] By adopting the above technical solution, the slide plate is made of copper. Copper has a low coefficient of friction, which can reduce the frictional resistance during the sliding process of the worktable, reduce the wear rate of the worktable, and thus extend the service life of the feeding device.

[0015] Optionally, the slide plate has an oil channel for storing oil on its surface facing the slide rail.

[0016] By adopting the above technical solution, oil is injected into the oil channel, and the oil lubricates the surface of the slide plate, further reducing the frictional resistance between the surface of the slide plate and the inner wall of the slide channel, reducing the wear rate of the worktable, and thus further extending the service life of the feeding device.

[0017] Optionally, the slide plate surface is provided with multiple threaded holes spaced apart, and the bolt end can pass through the threaded holes and be threaded and tightened to the base surface to form a fixed structure.

[0018] By adopting the above technical solution, when the slide plate is placed on the base surface, the bolt end is threaded through a threaded hole and tightened to fix it on the base surface, thus realizing the detachable installation between the slide plate and the base, facilitating the replacement of the slide plate, thereby improving the ease of use of the feeding device.

[0019] Optionally, the feeding device further includes at least two telescopic components, each corresponding to a workbench. Each telescopic component includes a fixed insert, a cover insert, and multiple connecting inserts. The multiple connecting inserts are sequentially fitted at their ends. One end of the fixed insert is connected to the surface of the workbench, and the other end of the fixed insert is slidably connected to the outer circumferential surface of one of the connecting inserts. The end of the cover insert is slidably connected to the inner wall of the inner cavity of one of the connecting inserts. The cover insert and the fixed insert are located at both ends of the multiple connecting inserts, and the inner cavities of the fixed insert, the cover insert, and the multiple connecting inserts all cover the slide plate surface.

[0020] By adopting the above technical solution, one end of the fixed panel is connected to the surface of the worktable, and the other end of the fixed panel is slidably connected to the outer circumference of one of the connecting panels. Multiple connecting panels are sequentially fitted at their ends. The cover panel and the fixed panel are located at both ends of the multiple connecting panels. When the worktable slides, it pushes the fixed panel to slide along the outer circumference of the connecting panel, making it less likely for the worktable to deviate when sliding on the base surface, thereby further improving the stability of the worktable sliding on the base surface. At the same time, the inner cavities of the fixed panel, the cover panel, and the multiple connecting panels all cover the slide plate surface, making the slide plate less likely to be exposed on the base surface and wear from external impacts, further extending the service life of the feeding device.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The workbench setup enables simultaneous loading and unloading of workpieces, improving processing efficiency, shortening processing cycles, and thus reducing processing costs. 2. The push-pull cylinder and push-pull block are designed to precisely control the sliding distance of the two worktables on the base surface, thereby improving the processing quality of the workpiece; 3. The support plate design allows the worktable to slide on the base surface without increasing the base's volume, reducing material input for the base and thus lowering the cost of the feeding device.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a hydraulic press slide structure. (Refer to...) Figure 1 The hydraulic press slide structure includes a feeding device 1 and a base 2 on the hydraulic press. The bottom of the base 2 abuts against the ground to form support. The surface of the base 2 facing the processing end of the hydraulic press is provided with a processing station. The feeding device 1 is installed on the base 2. The feeding device 1 can realize the synchronous feeding and unloading of workpieces at the processing station, improve the processing efficiency of workpieces, shorten the processing cycle of workpieces, and thus reduce the processing cost of workpieces.

[0029] Reference Figure 2 and Figure 3 The feeding device 1 includes two worktables 11, two push-pull components 12, two telescopic components 13, and multiple slide plates 14.

[0030] Reference Figure 1 Two worktables 11 are slidably connected to the two ends of the base 2 in the width direction, and the surfaces of the worktables 11 are for placing workpieces. When one worktable 11 slides along the surface of the base 2 toward the processing station, it drives the other worktable 11 to slide along the surface of the base 2 away from the processing station. When the hydraulic press processing end processes the workpiece on the worktable 11 at the processing station, the operator places the workpiece to be processed on the surface of the other worktable 11. When the workpiece at the processing station is processed, the worktable 11 with the processed workpiece slides along the surface of the base 2 away from the processing station, while the worktable 11 with the unprocessed workpiece slides along the surface of the base 2 toward the processing station. The hydraulic press processing end processes the workpiece at the processing station, realizing the synchronous loading and unloading of workpieces, improving the processing efficiency of workpieces, shortening the processing cycle of workpieces, and thus reducing the processing cost of workpieces.

[0031] Reference Figure 1 and Figure 2 The push-pull assembly 12 corresponds to the worktable 11. The push-pull assembly 12 pushes the worktable 11 to slide on the surface of the base 2. The push-pull assembly 12 includes a push-pull cylinder 121, a push-pull block 122 and multiple support plates 123. The end of the push-pull cylinder 121 is embedded in the side wall of the base 2 to form a fixed position. The piston rod axis of the push-pull cylinder 121 is parallel to the sliding direction of the worktable 11. The push-pull block 122 is fixed to the side of the worktable 11 away from the other worktable 11 by bolts. The piston rod end face of the push-pull cylinder 121 is fixed to the surface of the push-pull block 122.

[0032] Reference Figure 1 and Figure 2 When the piston rod of the push-pull cylinder 121 extends, it pushes the worktable 11 away from the processing station; when the piston rod of the push-pull cylinder 121 retracts, it pushes the worktable 11 closer to the processing station, and the worktable 11 is located on the processing station, so as to achieve precise control of the sliding distance of the two worktables 11 on the surface of the base 2, thereby improving the processing quality of the workpiece.

[0033] Reference Figure 2 and Figure 3 The number of support plates 123 can be two, three or more. In this embodiment, there are two support plates 123. The ends of the two support plates 123 are fixed to the two ends of the base 2 in the length direction by bolts. The length direction of the support plates 123 is parallel to the sliding direction of the worktable 11. When the worktable 11 is away from the processing station, the plate surface of the support plate 123, which is flush with the end face of the base 2, abuts against the bottom surface of the worktable 11 to form support. While ensuring the sliding area of ​​the worktable 11 on the surface of the base 2, it is not necessary to increase the volume of the base 2, thereby reducing the material input of the base 2 and reducing the input cost of the feeding device 1.

[0034] Reference Figure 2 and Figure 3 Multiple slides 14 are divided into multiple groups, with two groups of slides 14 corresponding to each other at both ends of the workbench 11 along its length. Multiple slides 14 in the same group are sequentially connected to the surface of the base 2, and the arrangement direction of the slides 14 in the same group is parallel to the width direction of the base 2. The remaining groups of slides 14 correspond one-to-one with the support plate 123, with multiple slides 14 in the same group sequentially connected to the surface of the support plate 123, and the arrangement direction of the slides 14 in the same group is parallel to the width direction of the base 2. Furthermore, the slides 14 in the same group on the support plate 123 are connected to the slides on the base 2. The set of slide plates 14 has a slide rail 111 on the bottom surface of the worktable 11 for the slide plate 14 to slide. The depth of the slide rail 111 is less than the thickness of the slide plate 14. When the worktable 11 slides on the surface of the base 2, it drives the slide plate 14 to slide on the inner wall of the slide rail 111, so that the worktable 11 is not easy to deviate during the sliding process, thereby improving the stability of the sliding of the worktable 11. At the same time, the thickness of the slide plate 14 is greater than the depth of the slide rail 111, ensuring that the inner wall of the slide rail 111 and the surface of the slide plate 14 slide in contact, reducing the wear between the worktable 11 and the base 2, thereby extending the service life of the feeding device 1.

[0035] Reference Figure 2 and Figure 3 In this embodiment, the slide plate 14 is made of copper. Copper has a low coefficient of friction, which reduces the frictional resistance between the surface of the slide plate 14 and the inner wall of the slide rail 111, reduces the wear rate on the worktable 11, and thus extends the service life of the feeding device 1.

[0036] Reference Figure 2 and Figure 3 The slide plate 14 has an oil channel 141 for storing oil on its surface facing the slide rail 111. The number of oil channels 141 can be one, two or more. In this embodiment, there are multiple oil channels 141, which increases the contact area between the oil and the surface of the slide plate 14. The oil fully lubricates the surface of the slide plate 14, reduces the frictional resistance between the surface of the slide plate 14 and the inner wall of the slide rail 111, reduces the wear rate of the worktable 11, and further extends the service life of the feeding device 1.

[0037] Reference Figure 2 and Figure 3 The slide plate 14 has multiple threaded holes 142 spaced apart on its surface. The multiple threaded holes 142 are divided into two groups, and the two groups of threaded holes 142 are located at the two ends of the width direction of the slide plate 14. The arrangement direction of the multiple threaded holes 142 in the same group is parallel to the length direction of the slide plate 14. The bolt ends pass through the threaded holes 142 and are screwed on to fix them to the surface of the base 2, thereby realizing the detachable fixation between the slide plate 14 and the base 2, which facilitates the replacement of the slide plate 14 and improves the ease of use of the feeding device 1.

[0038] Reference Figure 3 and Figure 4 The telescopic components 13 correspond one-to-one with the worktables 11. The telescopic components 13 include a fixed panel 131, a cover panel 132, and multiple connecting panels 133. One end of the fixed panel 131 is fixed to the side of the worktable 11 away from the other worktable 11 in the length direction. The other end of the fixed panel 131 is slidably connected to the outer peripheral surface of one of the connecting panels 133. The end of the cover panel 132 is slidably connected to the inner wall of one of the connecting panels 133. The cover panel 132 and the fixed panel 131 are located at both ends of the sliding direction of the multiple connecting panels 133, and the inner cavities of the fixed panel 131, the cover panel 132, and the multiple connecting panels 133 all cover the surface of the slide plate 14.

[0039] Reference Figure 3 and Figure 4 When the piston rod of the push-pull cylinder 121 retracts, it pushes the worktable 11 to slide along the surface of the base 2 toward the direction closer to the processing station, causing the fixed insert 131 to slide along the connecting insert 133 toward the direction away from the cover insert 132. The adjacent connecting inserts 133 move away from each other, and the inner cavities of the fixed insert 131, the cover insert 132, and the multiple connecting inserts 133 open and cover the slide plate 14, making the slide plate 14 less likely to be exposed on the surface of the base 2, reducing the probability of the slide plate 14 being damaged by external impact, thereby extending the service life of the feeding device 1.

[0040] Reference Figure 3 and Figure 4 When the piston rod of the push-pull cylinder 121 extends, it pushes the worktable 11 to slide away from the processing station along the surface of the base 2, causing the fixed panel 131 to slide along the outer periphery of the connecting panel 133 towards the cover panel 132. The adjacent connecting panels 133 move closer to each other, and the inner cavities of the fixed panel 131, the cover panel 132, and multiple connecting panels 133 are stacked in sequence to achieve storage, reducing the operating area of ​​the feeding device 1, thereby further improving the ease of use of the feeding device 1.

[0041] The implementation principle of the hydraulic press slide structure in this application embodiment is as follows: When the workpiece to be processed is placed on the surface of one of the workpiece tables, the piston rod of the push-pull cylinder 121 retracts, pushing the worktable 11 closer to the processing station, and the worktable 11 is located on the processing station. The hydraulic press processing end processes the workpiece on the worktable 11 at the processing station. At the same time, the operator places the workpiece to be processed on the surface of another worktable 11. When the workpiece at the processing station is processed, the piston rod of the push-pull cylinder 121 extends, pushing the worktable 11 with the processed workpiece away from the processing station. The piston rod of the other push-pull cylinder 121 retracts, pushing the worktable 11 with the unprocessed workpiece closer to the processing station. This realizes the synchronous loading and unloading of workpieces, improves the processing efficiency of workpieces, shortens the processing cycle of workpieces, and thus reduces the processing cost of workpieces.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
