Description

Technical Field

[0001] This utility model relates to a rubber product processing method, and in particular to a device for beating, shaping and deburring a vulcanized circular rubber pad. Background Technology

[0002] In the production of pressure reducing valves, to facilitate gas pressure regulation within the valve body, a circular rubber pad is machined during the production of the diaphragm. This pad is then installed on the diaphragm. Through the installation of the diaphragm and the pressure reducing valve, the outer edge of the rubber pad can seal the pressure reducing valve, facilitating the conduction of work by the fluid entering the valve. This allows for the next stage of fluid pressure stabilization, thus enabling the pressure reducing valve to perform its pressure-reducing function.

[0003] Currently, the processing of round rubber gaskets for pressure reducing valves involves placing the raw material on a deburring die after vulcanization, and then pressing it downwards with a stamping press to deform the rubber gasket and separate the waste material from the gasket. The vulcanized round rubber gasket is then deburred on the outer diameter and perforated on the inner diameter. This process is inefficient, and the waste material after perforation often gets stuck in the die and is difficult to remove, affecting subsequent deburring work. Therefore, it is necessary to design a hammering and shaping deburring device that can fully process the rubber gasket and quickly remove both the finished product and waste material. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a device for beating, shaping and deburring a vulcanized circular rubber pad, which can fully process the rubber pad and achieve the purpose of rapid removal of products and waste.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A device for hammering, shaping, and deburring a vulcanized circular rubber pad includes a stamping machine body, a die set on the worktable of the stamping machine body, and a stamping block set on the stamping end of the stamping machine body. The die has multiple inner dies, and the stamping block has an inner punch pad that works with the multiple inner dies. The upper edge of the die has a conical outer die. A receiving groove is provided between the outer die and the inner dies. An opening is provided between the receiving groove and the outer die. The bottom of the die has an ejector assembly for removing scrap material.

[0007] The stamping block is fitted with an outer cutting ring that works with the outer mold. The outer cutting ring and the inner punch pad are connected by the same push cover for vibration separation of the processed product and scrap.

[0008] Preferably, the outer mold and the inner mold are of the same height, the number of openings is two sets, the two sets of openings are arranged opposite each other, the openings are flush with the bottom of the storage groove, and a support is provided in the opening.

[0009] Preferably, a fan is provided on the rear side of the stamping machine worktable, and the air outlet of the fan is distributed opposite to the die.

[0010] Preferably, the ejection assembly includes an electric push rod and a top plate disposed at the telescopic end of the electric push rod. The top of the top plate is provided with a plurality of push rods that penetrate the inner mold, and the top of the push rods is provided with rubber blocks.

[0011] Preferably, the outer side of the top plate is provided with an extension plate that penetrates the ejection assembly, and the top of the extension plate is provided with an external push rod, the height of which is lower than that of the outer mold.

[0012] Preferably, the lower end of the outer tangent ring is lower than the lower end of the inner punch pad, and the inner side of the outer tangent ring is provided with a chamfered portion.

[0013] Preferably, multiple inner punch pads penetrate the push cover, the push cover is made of rubber material, and the push cover has multiple through holes.

[0014] Compared with existing technologies, the vulcanized circular rubber pad hammering and shaping deburring device provided by this utility model can fully process the rubber pad, achieving rapid removal of both product and waste. Specifically, the use of inner and outer molds at the same height on the die, the inner punch and outer cutting ring on the stamping block, and the staggered hammering of the inner chamfer of the outer cutting ring with the outer mold, enable the deburring device to not only perform internal hole processing on the rubber pad but also deburr the outer surface of the rubber pad, achieving one-time forming of the rubber pad, saving processing steps and costs, and improving the processing efficiency of the deburring device.

[0015] Furthermore, the use of the push cover can separate the waste material from the rubber pad. The ejector component at the lower end of the die allows the ejector component to use the ejector rod and the outer push rod to simultaneously eject the waste material from the inner and outer molds. Combined with the airflow from the blower, the airflow is guided towards the waste material, which can be quickly removed from the deburring equipment. This facilitates continuous processing of the deburring equipment, increases the cleanliness of the equipment, and makes the deburring equipment more efficient.

[0016] It should be understood that the general descriptions and details herein are exemplary and illustrative only and are not intended to limit this disclosure.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] As attached Figure 1 To be continued Figure 5As shown, the vulcanized circular rubber pad beating and shaping deburring device provided in the embodiment of this utility model is used to remove the inner and outer diameter waste of the diaphragm rubber pad in the one-way valve while simultaneously cleaning the cutting waste on the die 11, thus realizing continuous processing of the rubber pad. Using the existing stamping and cutting technology of a stamping machine, the material to be processed is placed on the die 11 and supported by the inner die 111. The downward pressure of the stamping block 12 on the stamping machine body 1 on the die 11 causes the inner punch pad 121 on the stamping block 12 to strike the inner die 111, removing the inner diameter waste of the material. Then, by setting the outer mold 112 on the upper edge of the die 11, and the top of the outer mold 112 is a conical structure, an annular striking edge can be added to the die 11. Then, an outer cutting ring 4 that works with the outer mold 112 is set at the lower end of the stamping block 12, which facilitates the simultaneous stamping and striking of the inner mold 111 and the inner stamping pad 121 to remove waste material from the inner and outer diameters of the rubber pad. Next, by using the top component set at the bottom of the die 11, the waste material in the inner mold 111 can be pushed upward and pushed out of the inner mold 111. The waste material is then preferentially collected in the collection slot 113. By opening 2 between the receiving groove 113 and the outer mold 112, the waste material in the receiving groove 113 can be blown out by the cutting die 11 using wind power, realizing the rapid transfer of waste material and increasing the rapid cleaning of waste material in the inner diameter of the rubber pad; then, by using the same push cover 42 set on the outer cutting ring 4 and the inner punch pad 121, the elastic pushing structure on the impact block can be increased. When the stamping machine body 1 uses the stamping block 12 to knock down the edge, the push cover 42 comes into contact with the material and deforms, which can drive the product and the scrap material to vibrate at the same time, separating the product and the scrap material, and completing the edge removal work of the inner and outer diameters of the rubber pad.

[0027] It is worth noting that, for example Figure 5 As shown, in order to simultaneously remove the rubber material at the top of the inner mold 111 and the outer mold 112, the outer mold 112 and the inner mold 111 are set to the same height. When the opening 2 and the receiving groove 113 are opened, the bottom of the opening 2 and the receiving groove 113 can be set flush. Two sets of opening 2 can be set in opposite directions to facilitate the collection of waste material in the receiving groove 113 and its quick removal. This increases the integration between the opening 2 and the receiving groove 113, avoids the retention of waste material, and increases the cleanliness of waste material cleaning. In order to facilitate the stamping of the die 11 by the stamping machine body 1, a support part 21 can be set in the opening 2 to increase the structural stability of the die 11 at the opening 2, avoid its structural deformation, and improve the processing effect of the deburring equipment.

[0028] To make it easier to clean up the debris knocked off, such as Figure 1 As shown, a fan 5 can be installed on the rear side of the worktable of the stamping machine body 1. By rotating the fan 5, gas can be transmitted to the die 11. After the gas passes through the port 2, it can automatically remove the waste material, thereby improving the waste material cleaning rate.

[0029] It is worth noting that, such as Figure 5 As shown, in some embodiments, the ejector assembly 3 can use a retractable drive structure to push out waste material retained in the inner mold 111 or stuck outside the outer mold 112 from bottom to top, thereby achieving waste material removal. This utility model, as described above... Figure 5 As shown, the ejector assembly 3 can use an electric push rod 31 as a telescopic drive structure. A top plate 32 can be set at the telescopic end of the electric push rod 31. A push rod 33 that penetrates the inner mold 111 is set at the top of the top plate 32. A rubber block 34 is then fixed at the top of the push rod 33. By pushing the push rod 33 in the inner mold 111 through the electric push rod 31, the waste material in the inner mold 111 can be pushed out and collected preferentially using the collection groove 113 for continuous knocking and edge removal. Alternatively, the waste material can be blown out by the air force of the blower 5 through the opening 2 to achieve waste material cleaning.

[0030] Furthermore, in order to remove waste material from the outer edge of the rubber pad, such as... Figure 5 As shown, an extension plate 35 that penetrates the ejector assembly 3 can be provided on the outer side of the top plate 32. An outer push rod 36 lower than the outer mold 112 is provided on the top of the extension plate 35. When the ejector assembly 3 cleans up the waste, the extension plate 35 can move upward with the movement of the top plate 32 through the electric extension and retraction of the electric push rod 31, which drives the outer push rod 36 to push the waste outside the outer mold 112 and separate it from the lower mold. Then, the blower 5 blows the waste away from the die 11, completing the waste cleaning work. This facilitates the continuous edge removal work of the edge removal equipment and improves the processing efficiency of the equipment.

[0031] To facilitate the separation of trimmed material from waste, such as Figure 3 As shown in Figure 4, the lower end of the outer cutting ring 4 is lower than the lower end of the inner punch pad 121. A chamfered portion 41 is provided on the inner side of the outer cutting ring 4. When the outer cutting ring 4 and the outer mold 112 are hammered and cut, the chamfered portion 41 will be staggered on the outer side of the outer mold 112, realizing the staggered cutting of the outer cutting ring 4 and the outer mold 112, removing the waste material on the outer edge of the rubber pad, increasing the cutting area between the outer cutting ring 4 and the material, facilitating the stamping block 12 to perform stamping and edge removal, and simultaneously removing the waste material on the inner and outer diameters of the material, reducing the processing steps of the product, reducing the production cost of the product, and improving the processing efficiency.

[0032] To separate the trimmed product from the waste and prevent waste from accumulating, the lower ends of the push cover 42 and the inner punch pad 121 can be set to the same height, or slightly higher than the inner punch pad 121. Multiple inner punch pads 121 on the stamping block 12 penetrate the push cover 42. The push cover 42 can be made of rubber to provide conditions for the trimming work of the inner punch pad 121 and the inner mold 111. Multiple through holes 43 are then opened on the push cover 42 to facilitate the work of the stamping block 12 against the die 11 during processing, pushing gas into the push cover 42 for airflow and ventilation between the push cover 42 and the stamping block 12, reducing the temperature of the stamping block 12 and facilitating heat dissipation. Furthermore, the use of the rubber push cover 42 facilitates the separation of the processed product from the impact block, vibrating the product and waste to achieve separation, increasing the ease of waste removal and improving the waste removal rate.

[0033] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
