Description

Technical Field

[0001] The present application relates to the technical field of rubber production and processing, and in particular to a rubber punching machine. Background Art

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature. Rubber can produce large deformation under very small external force and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer.

[0003] During the production of rubber products, punching machines are used to punch holes into the rubber, allowing for the next step in the manufacturing process. A punching machine is a mechanical device that uses a power mechanism to drive a punching die into the material to create holes.

[0004] Regarding the aforementioned related technologies, during stamping operations, operators typically place the rubber block directly on the bottom of the stamping machine and then operate the press to apply downward pressure to process the rubber block. Since the rubber block lacks a positioning device, the stamping process can cause the rubber block to shift in position, adversely affecting the processing quality of the rubber block. Therefore, improvements are needed. Utility Model Content

[0005] In order to improve the quality of the rubber block after punching, the present application provides a rubber punching machine.

[0006] The rubber stamping machine provided in this application adopts the following technical solution:

[0007] A rubber stamping machine includes a frame, a positioning plate, a pressure plate and a stamping assembly. The positioning plate is arranged on the frame and has a plurality of first through holes. The first through holes are spaced apart on the positioning plate and are used to position the rubber. The positioning plate is connected to a plurality of pins. The pressure plate has a plurality of sockets. The pins are respectively inserted into the sockets. The pressure plate has a plurality of second through holes. The second through holes are used for rubber to pass through. The pressure plate is used to press the rubber onto the positioning plate. The stamping assembly is arranged on the frame and is used to punch the positioned rubber.

[0008] By adopting this technical solution, during production, the operator first places the rubber on the positioning plate and pre-positions it using the first through-hole. The operator then places the pressure plate on the positioning plate, securing the product between the pressure plate and the positioning plate using the pins and holes. Finally, the punching assembly is used to punch the positioned rubber. This prevents the rubber from shifting during punching, thereby improving the quality of the rubber block after punching.

[0009] Preferably, the punching assembly includes a punch and a driving member, the punch is located above the positioning plate, the punch is arranged to be raised and lowered, and is used to punch holes in the rubber; the driving member is connected to the punch and is used to control the up and down movement of the punch.

[0010] By adopting the above technical solution, the driving member can control the punch to move downward, so that the punch presses on the rubber in the second through hole, thereby forming a hole in the rubber.

[0011] Preferably, the driving member is a pneumatic cylinder or a hydraulic cylinder.

[0012] By adopting the above technical solution, either the pneumatic cylinder or the hydraulic cylinder can provide sufficient punching force for the punch.

[0013] Preferably, a control member is further included, the frame is provided with a guide rail, the positioning plate is slidably connected to the guide rail, and the control member is connected to the positioning plate and is used to control the movement of the positioning plate.

[0014] By adopting this technical solution, the control unit can control the horizontal movement of the positioning plate on the guide rail, thereby changing the relative position of the rubber to the stamping assembly. When stamping is required, the control unit moves the positioning plate directly below the stamping assembly. When stamping is completed, the control unit pushes the positioning plate out of the stamping station, making it easier for the operator to unload the material.

[0015] Preferably, handles are connected to both sides of the pressing plate, and the handles are used for operators to grasp.

[0016] By adopting the above technical solution, the presence of the handle can facilitate the operator to grasp, thereby controlling the pressure plate to be combined with the positioning plate or to be separated from the positioning plate.

[0017] Preferably, a waste collection box is further provided on the frame, and the waste collection box is located below the stamping assembly. The waste collection box is opened and is used to collect waste after rubber stamping.

[0018] By adopting the above technical solution, waste is generated from the rubber after stamping, and this part of the waste falls from the first through hole into the waste collection box so that subsequent operators can centrally process the waste.

[0019] Preferably, a discharge port is provided on the side wall of the waste collection box, and the discharge port is communicated with the bottom of the waste collection box, and the bottom of the waste collection box is inclined.

[0020] By adopting the above technical solution, when waste needs to be cleaned, the staff can open the discharge port. Under the action of the gravity component, the waste will slide down along the bottom of the waste collection box, so that the waste in the waste collection box can be processed, and then the discharge port can be closed after processing.

[0021] Preferably, it also includes a compression spring and a limit plate, the compression spring is arranged on the punch, and the expansion and contraction direction of the compression spring is parallel to the moving direction of the punch; the limit plate is movably arranged on the punch and connected to the compression spring, and the limit plate is used to be pressed on the pressure plate.

[0022] By adopting the above technical solution, when the punch presses downward and contacts the rubber, the limit plate will abut against the pressure plate. As the punch continues to press downward, under the action of the compression spring, the compression spring will elastically deform and be compressed, so that the limit plate is always pressed against the pressure plate, further improving the stability of the rubber position during the stamping process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] (1) By setting the positioning plate and the pressing plate, the rubber to be punched can be pressed between the positioning plate and the pressing plate, and the position of the rubber is not easily offset during punching, thereby improving the punching quality of the rubber block.

[0025] (2) By setting up control parts and guide rails, the control parts can control the horizontal movement of the positioning plate on the guide rails, thereby changing the relative position of the rubber relative to the stamping assembly, making it convenient for operators to adjust the position of the rubber according to actual needs and improving practicality.

[0026] (3) By setting up a waste collection box, the waste generated by the rubber after stamping can fall into the waste collection box, making it convenient for subsequent operators to centrally handle the waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In the description of the embodiments of this application, unless otherwise specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, integration, or mechanical connections. Those skilled in the art will understand the specific meanings of these terms in the embodiments of this application based on specific circumstances.

[0035] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine the different embodiments or examples and features of the different embodiments or examples shown in the present application.

[0036] The present application embodiment discloses a rubber punching machine. Figure 1The rubber stamping machine includes a frame 1, a positioning plate 2, a pressure plate 3 and a stamping assembly 4. The frame 1 serves as a carrier and is fixedly installed on the ground. The positioning plate 2 is installed on the frame 1 and is provided with a plurality of first through holes 7, which are circular holes; each first through hole 7 is spaced apart on the same side of the positioning plate 2 and is used to position the rubber. A plurality of pins 5 are fixedly connected to the positioning plate 2, and the pins 5 are located at the outer edge of the positioning plate 2; a plurality of sockets 6 are provided on the pressure plate 3, and the number of the sockets 6 is the same as the number of the pins 5. Each pin 5 is respectively inserted into each socket 6, and the detachable connection between the pressure plate 3 and the positioning plate 2 is realized by the cooperation of the pins 5 and the sockets 6. A plurality of second through holes 8 are provided on the pressure plate 3, and each second through hole 8 is used for rubber to pass through, and the pressure plate 3 is used to press the rubber onto the positioning plate 2. Among them, handles 9 are fixedly connected to both sides of the pressure plate 3, and the handles 9 are used for the operator to grasp. The presence of the handle 9 makes it easier for the operator to grasp it, thereby controlling the pressing plate 3 to be combined with the positioning plate 2 or to be separated from the positioning plate 2 .

[0037] The punch assembly 4 is mounted on the frame 1, near the positioning plate 2. It is used to punch holes in the positioned rubber. Specifically, the punch assembly 4 includes a punch 41 and a driver 42. The punch 41 is arranged to rise and fall on the frame 1, above the positioning plate 2, and is used to punch holes in the rubber. The driver 42 is connected to the punch 41 and controls its vertical movement. The driver 42 is a pneumatic or hydraulic cylinder.

[0038] During production, the operator first places the rubber on the positioning plate 2 and pre-positions it using the first through-holes 7. Next, the pressing plate 3 is placed over the positioning plate 2, and the product is secured between the pressing plate 3 and the positioning plate 2 by the engagement of the pins 5 and the sockets 6. Finally, the driver 42 is activated, controlling the punch 41 to press downward, punching the positioned rubber. The pressing plate 3 prevents the rubber from shifting during punching, thereby improving the quality of the punched rubber.

[0039] The punch 41 is also equipped with a plurality of compression springs 10. The compression springs 10 are parallel to each other and spaced apart. The expansion and contraction directions of the compression springs 10 are parallel to the movement direction of the punch 41. A limit plate 11 is movably mounted on the punch 41 and faces the pressure plate 3. The ends of the compression springs 10 are connected to the punch 41 and the limit plate 11, respectively. The limit plate 11 is used to press on the pressure plate 3.

[0040] When the punch 41 presses downward and contacts the rubber, the limit plate 11 will abut against the pressure plate 3. As the punch 41 continues to press downward, under the action of the compression spring 10, the compression spring 10 will elastically deform and be compressed, so that the limit plate 11 is always tightly pressed against the pressure plate 3, so that the pressure plate 3 continues to exert a pressure on the rubber, further improving the stability of the rubber's position during the stamping process.

[0041] In some embodiments, a guide rail 12 is horizontally mounted on the frame 1, and the positioning plate 2 is slidably connected to the guide rail 12. A control component 13 is also provided on the frame 1, and the control component 13 is connected to the positioning plate 2 and is used to control the horizontal movement of the positioning plate 2. In this embodiment, the control component 13 is a linear cylinder or an electric push rod. The control component 13 controls the horizontal movement of the positioning plate 2 on the guide rail 12 to change the relative position of the rubber relative to the stamping assembly 4. When stamping is required, the control component 13 is used to move the positioning plate 2 to directly below the stamping assembly 4; when the stamping is completed, the control component 13 is used to push the positioning plate 2 out of the stamping station to facilitate the operator to unload the material.

[0042] Furthermore, a waste collection box 14 is mounted on the frame 1 and is located below the stamping assembly 4. This box 14 has an opening for collecting waste rubber from stamping. A discharge port (not shown) is defined on the sidewall of the box 14 and communicates with the bottom of the box 14. The bottom of the box 14 is angled downward toward the discharge port.

[0043] After the rubber is stamped, waste material is generated. This waste material falls through the first through hole 7 into the waste collection box 14, so that the operator can subsequently collect and process the waste material. When the waste material needs to be cleaned up, the operator can open the discharge port. Under the action of the force of gravity, the waste material will slide down the bottom of the waste collection box 14, and the waste material in the waste collection box 14 can be processed. After processing, the discharge port can be closed.

[0044] The implementation principle of a rubber punching machine in an embodiment of the present application is as follows: During the production process, the operator first places the rubber on the positioning plate 2 and uses the through-holes on the positioning plate 2 to perform preliminary positioning of the rubber. Subsequently, the pressing plate 3 is placed on the positioning plate 2, and the precise fit between the plug 5 and the socket 6 ensures that the product is firmly fixed between the pressing plate 3 and the positioning plate 2. Finally, the driving member 42 is started, controlling the punch 41 to apply downward pressure to accurately punch the positioned rubber. Due to the action of the pressing plate 3, the position of the rubber remains stable during the punching process and is not easily offset, thereby improving the quality of the rubber after punching.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
