Description

Technical Field

[0001] This invention belongs to the field of hydraulic press technology, specifically a four-column hydraulic press for processing plastic materials. Background Technology

[0002] A four-column hydraulic press, also known as an oil press, belongs to the category of mechanical equipment. It is a general-purpose pressure device that processes plastic materials through hydraulic transmission based on Pascal's law. Its typical structure consists of a four-column, three-plate frame, hydraulic cylinders, crossbeams, columns, and a hydraulic control system. It can perform processes such as pressing, stretching, and straightening.

[0003] In the existing technology, four-column hydraulic presses are often used for processing plastic materials, but their structural design has significant defects: during the stamping process, the impact force and vibration generated when the hydraulic cylinder drives the stamping seat to move up and down can easily cause the connection between components to shake, the overall machine body to vibrate, and even cause a reduction in material processing accuracy, accelerated equipment wear, or safety hazards.

[0004] In view of this, a four-column hydraulic press for processing plastic materials is proposed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Given the following technical problems in the existing technology: In the existing technology, four-column hydraulic presses are often used for processing plastic materials, but their structural design has significant defects: During the stamping process, the impact force and vibration generated when the hydraulic cylinder drives the stamping seat to move up and down can easily cause the connection between components to shake, the overall machine body to vibrate, and even cause a reduction in material processing accuracy, accelerated equipment wear, or safety hazards.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a four-column hydraulic press for processing plastic materials, comprising a base, a stamping seat, and an upper support;

[0008] A guide post is fitted at the corner of the upper surface of the base. The stamping seat moves telescopically on the guide post. The upper support is placed on the top of the guide post. An oil tank is fitted on the top of the upper support. A hydraulic cylinder is installed on the side of the upper support facing the stamping seat. The oil tank is used to supply the hydraulic cylinder.

[0009] The material to be processed is placed on the base, and the stamping seat is driven by a hydraulic cylinder to stamp the material.

[0010] The output end of the hydraulic cylinder is connected to the chassis, the chassis is in contact with the upper surface of the stamping seat, and the chassis has a reserved vertical channel that matches the preset locking pin.

[0011] The stamping base has a prefabricated channel, a bottom support base is embedded in the prefabricated channel, and a preset locking pin is configured in the bottom support base;

[0012] The preset locking pin is positioned at the center of the bottom support base.

[0013] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, a limiting channel A is milled on the upper part of the chassis, and a double-joint cable is embedded in the limiting channel A. The double-joint cable can be restricted after docking at the connecting seat, so as to play a role in secure connection. A retention channel is milled on the inner edge of the limiting channel A to restrict one end of the double-joint cable, thereby further improving the overall stability.

[0014] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, the bottom support seat is equipped with several bending frames in the middle section. The bending frames are curved, and the original linkage bending frames are bulged to push against the middle section of the prefabricated channel, making the bottom support seat and the preset locking column more secure in the prefabricated channel.

[0015] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, the lower part of the bottom support seat has a pre-reserved irregular cavity, the irregular cavity is adapted to the end specifications of the preset locking column, thereby restricting the preset locking column, and the irregular cavity is connected to the middle part of the bottom support seat.

[0016] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, the bottom support is provided with a limiting sleeve, wherein the limiting sleeve restricts the original sleeve.

[0017] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, the outer contour of the bending frame is milled with protrusions, wherein after the bending frame bulges and undergoes bending, the protrusions on it can come into contact with the inner edge of the prefabricated channel.

[0018] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, the lower inner edge of the prefabricated channel is milled with an irregular channel, the specifications of which are adapted to the lower specifications of the bottom support, wherein the irregular channel can restrict the bottom support.

[0019] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, the limiting sleeve is hinged to the original sleeve, and the original sleeve is threadedly engaged with the preset locking column. When the original sleeve rotates, with the engagement of the thread, the original sleeve will move towards the depth of the prefabricated channel. At this time, it can be linked with the bending frame to bend and move towards the inner edge of the prefabricated channel, so that the two are firmly connected.

[0020] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, a connecting seat is embedded in the limiting channel A. The connecting seat is threadedly fitted to the outside of a preset locking column. A medium-shaped extension and a large-shaped extension are milled on the outer contour of the middle section of the connecting seat. A spiral channel is milled on the outer contour of the medium-shaped extension of the connecting seat. The double-joint cable extends and is embedded in the spiral channel.

[0021] As a preferred technical solution for a four-column hydraulic press for processing plastic materials, a limiting channel B is milled on the outer contour of the large extension of the connecting seat, wherein the middle section of the double-joint cable is embedded in the spiral channel, and one end of the double-joint cable passing through the spiral channel is engaged in the limiting channel B to improve the overall stability. The end of the double-joint cable away from the limiting channel A is connected to the limiting channel B.

[0022] The beneficial effects of this invention are:

[0023] 1. The prefabricated channel is embedded in the bottom support base, and the curved bulge and protrusion of the bending frame are used to contact the inner edge of the channel to achieve a firm fixation of the pre-set locking column and support base; at the same time, the adaptive design of the irregular cavity and irregular channel further restricts the displacement of the components and prevents shaking or displacement caused by impact during the stamping process.

[0024] 2. The interlocking and winding of the double-jointed cable in the limiting channel A, helical channel, and limiting channel B ensures a tight connection between the chassis and the connecting seat. Under external impact, the cable can pull on the connecting seat, providing cushioning and traction, and improving the vibration resistance between components.

[0041] Example, refer to Figure 1 A four-column hydraulic press for processing plastic materials includes a base 10, a stamping seat 20, and an upper support 30;

[0042] A guide post 11 is installed at the corner of the upper surface of the base 10. The stamping seat 20 moves telescopically on the guide post 11. The upper support 30 is placed on the top of the guide post 11. An oil tank 31 is installed on the top of the upper support 30. A hydraulic cylinder 40 is installed on the side of the upper support 30 facing the stamping seat 20. The oil tank 31 is used to supply the hydraulic cylinder 40.

[0043] The material to be processed is placed on the base 10, and the stamping seat 20 is driven by the hydraulic cylinder 40 to stamp the material.

[0044] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The output end of the hydraulic cylinder 40 is connected to the chassis 60, which is in contact with the upper surface of the stamping seat 20. A limiting channel A61 is milled on the upper part of the chassis 60, and a double-jointed cable 62 is embedded in the limiting channel A61. The double-jointed cable 62 can be limited after docking with the connecting seat 63, so as to ensure a reliable connection. A vertical channel adapted to the preset locking pin 50 is reserved on the chassis 60. A retention channel is milled on the inner edge of the limiting channel A61 to limit one end of the double-jointed cable 62, further improving the overall stability.

[0045] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8The stamping base 20 has a prefabricated channel 21, in which a bottom support base 52 is embedded. A pre-set locking pin 50 is installed in the bottom support base 52. Several bending brackets 53 are arranged in the middle section of the bottom support base 52. The bending brackets 53 are curved, and the original sleeve 51 bulges in conjunction with the bending brackets 53 to push against the middle section of the prefabricated channel 21, making the bottom support base 52 and the pre-set locking pins 50 more secure within the prefabricated channel 21. The lower part of the seat 52 has a pre-reserved irregular cavity 54, which is compatible with the end specification of the preset locking post 50 to restrict the preset locking post 50; a limiting sleeve 55 is provided on the bottom support seat 52, wherein the limiting sleeve 55 restricts the original sleeve 51; a protrusion 56 is milled on the outer contour of the bending frame 53, wherein the protrusion 56 on the bending frame 53 can contact the inner edge of the prefabricated channel 21 after the bending frame 53 bulges and bends; the irregular cavity 54 is connected to the middle part of the bottom support seat 52.

[0046] Reference Figure 2 and Figure 3 The preset locking pin 50 is positioned at the center of the bottom support base 52.

[0047] Reference Figure 4 , Figure 7 and Figure 8 A shaped channel 22 is milled along the inner edge below the prefabricated channel 21. The specifications of the shaped channel 22 are adapted to the specifications of the bottom support 52. The shaped channel 22 can restrict the bottom support 52.

[0048] Reference Figure 3 and Figure 7 The original sleeve 51 is hinged in the limited sleeve 55. The original sleeve 51 is threadedly connected to the preset locking post 50. When the original sleeve 51 rotates, the threaded connection causes the original sleeve 51 to move towards the depth of the prefabricated channel 21. At this time, it can be linked to the bending frame 53 to bend and move towards the inner edge of the prefabricated channel 21, so that the two are firmly connected.

[0049] Reference Figure 4 , Figure 5 and Figure 6A connecting seat 63 is embedded in the limiting channel A61. The connecting seat 63 is threadedly engaged with the preset locking pin 50. The middle section of the outer contour of the connecting seat 63 is provided with a medium-shaped extension and a large-shaped extension. A spiral channel 64 is milled on the outer contour of the medium-shaped extension of the connecting seat 63, and a limiting channel B65 is milled on the outer contour of the large-shaped extension of the connecting seat 63. The middle section of the double-jointed cable 62 is embedded in the spiral channel 64. One end of the double-jointed cable 62 passing through the spiral channel 64 is engaged in the limiting channel B65 to improve the overall stability. The double-jointed cable 62 extends into the spiral channel 64, and the end of the double-jointed cable 62 away from the limiting channel A61 is connected to the limiting channel B65.

[0050] The above steps achieve the following: The preset locking pin 50 and the bottom support base 52 are connected, so that the protruding part at the end of the preset locking pin 50 is in the irregular cavity 54. The bottom support base 52 is then embedded into the prefabricated channel 21. The irregular channel 22 initially defines the position of the bottom support base 52. Then, the extended portion of the original sleeve 51 is rotated. Under the action of the threaded connection, the original sleeve 51 moves deeper into the prefabricated channel 21. At this moment, the bending frame 53 is bent and comes into contact with the inner edge of the prefabricated channel 21. The bottom support base 52 is then stably positioned in the prefabricated channel 21. Next, the chassis 60 is placed on the stamping seat 20. The bulge of the chassis 60 matches the slope angle of the prefabricated channel 21 to ensure the accuracy of the assembly. One end of the double-jointed cable 62 is then embedded into… The inner edge of the limiting channel A61 is restricted, and then the connecting seat 63 is rotated and aligned with the preset locking pin 50. As the rotation continues, the connecting seat 63 is finally aligned with the limiting channel A61 to restrict the chassis 60. At this time, the double-jointed cable 62 is embedded in the spiral channel 64, and its other end is embedded in the limiting channel B65, so that the connecting seat 63 is combined with the chassis 60. When subjected to impact, the double-jointed cable 62 can pull the connecting seat 63 to improve the overall stability. During material processing, the material to be processed is placed on the base 10, and the upper and lower extension and retraction movement of the stamping seat 20 is controlled by the hydraulic cylinder 40 to stamp the material to be processed. During this process, the double-jointed cable 62 and other accessories can improve the overall stability during stamping.

[0051] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
