Description

Technical Field

[0001] This utility model relates to the field of elastic module processing equipment technology, and in particular to an automatic hot pressing and cooling device for elastic modules. Background Technology

[0002] Because elastic grinding blocks have the characteristics of good contouring effect, strong grinding ability, high polishing gloss and no grinding marks, they are often used to perform contouring full polishing or semi polishing on the surface of antique tiles, polished crystal tiles and glazed tiles, so the market demand for elastic grinding blocks is increasing.

[0003] Currently, the production process of elastic grinding blocks involves steps such as slurry preparation, mold loading, hot pressing, cooling and curing, and demolding. Among them, the hot pressing and cooling processes of elastic grinding blocks require a significant amount of manual labor. For example, after the mold is loaded, the molded shaped mold frame needs to be manually moved to the heating plate of the hot press. After hot pressing, the shaped mold frame needs to be manually pulled out, and the demolded elastic module blank is left to cool on the table.

[0004] However, the existing technology still has the following drawbacks:

[0005] 1. In the current production and processing of elastic abrasive blocks, the elastic abrasive block blanks after hot pressing and demolding need to be manually moved to the table for static cooling. The cooling time is long, the cooling effect is poor, and the cooling efficiency is low. Moreover, when the molding frame is not completely cooled down before re-molding, it is easy to cause the powder to solidify and produce air holes. The resulting elastic abrasive blocks are easy to scratch the customer's products and cause them to be scrapped.

[0006] 2. In the current production and processing of elastic grinding blocks, after the mold is installed, the shaping mold frame and raw materials need to be manually moved to the hot press for hot pressing. Moreover, after hot pressing, the shaping mold frame and elastic grinding block blank need to be manually pulled out, which is time-consuming, labor-intensive, and has high labor costs. There is also a risk of burns. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic hot pressing and cooling device for elastic modules.

[0008] The objective of this utility model is achieved through the following technical solution: an automatic hot pressing and cooling device for elastic modules, comprising a worktable, wherein the worktable is divided into a hot pressing zone and a cooling zone, the hot pressing zone and the cooling zone being arranged side by side, the hot pressing zone being provided with a lifting pressure seat for hot pressing elastic grinding blocks; the cooling zone being provided with a cooling system, the cooling system having a cooling chamber and a water-cooled spray mechanism communicating with the cooling chamber, the cooling chamber being located within the worktable in the cooling zone, for heat conduction cooling of the elastic grinding blocks after hot pressing; the water-cooled spray mechanism being installed on the lifting pressure seat, its spray outlet being located directly above the cooling zone, for spraying water to cool the elastic grinding blocks after hot pressing.

[0009] Furthermore, the water-cooled spray mechanism is equipped with fan blades, and the spray outlet is located at the bottom of the fan blades for spraying water mist downwards.

[0010] Furthermore, the odd-numbered or even-numbered fan blades of the water-cooled spray mechanism are provided with spray outlet holes, and a plurality of spray outlet holes are arranged in an array along the bottom length direction of the fan blades.

[0011] Furthermore, each fan blade of the water-cooled spray mechanism is provided with a spray outlet hole in its circumferential arrangement, and a plurality of spray outlet holes are arranged in an array along the bottom length direction of the fan blade, and the diameter of the spray outlet holes is 0.3mm-1mm.

[0012] Furthermore, the cooling chamber is integrally formed within the workbench, and the cooling chamber is configured with several interconnected circulating cooling pipes.

[0013] Furthermore, a water storage tank is provided in the base of the workbench, and the water storage tank is connected to the cooling chamber.

[0014] Furthermore, the lifting pressure seat is positioned above the hot pressing area of ​​the workbench via a guide column, and the water-cooled spray mechanism is connected to the lifting pressure seat via a support arm. Both the support arm and the guide column are hollow and connected to the water storage tank.

[0015] Furthermore, the worktable is equipped with a pusher cylinder, the pusher rod of which is connected to a pusher frame, and the hot-pressed elastic grinding block is pushed from the hot-pressing zone to the cooling zone through the pusher frame.

[0016] Furthermore, a feed inlet for feeding is provided on one side of the push frame.

[0017] Furthermore, the automatic hot pressing and cooling device for the elastic module also includes a feeding robot, which is located on one side of the worktable and automatically feeds material into the push frame from the feed port.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) In this embodiment, a cooling chamber is integrated into the workbench and the corresponding cooling area. Cold water is injected into the cooling chamber to conduct heat to cool the elastic grinding blocks on the cooling area. A water-cooling spray mechanism is set on the lifting pressure seat. Through the synergistic effect of the water-cooling spray and the heat conduction of the cooling chamber, the cooling time of each elastic grinding block is shortened from the original 20 minutes to 5 minutes. This avoids the problems of low efficiency and uneven cooling caused by manually moving the blocks to the workbench for static cooling. The synergistic effect of water-cooling spray and heat conduction improves the uniformity of cooling, thereby enhancing the consistency of the hardness of the elastic grinding blocks. Forced cooling ensures that the molding mold frame is completely cooled before recycling, preventing the preheating and solidification of powder from producing air holes, avoiding affecting the molding quality of the elastic grinding blocks, thereby improving the product yield and preventing the customer's products from being scratched or scrapped.

[0020] (2) By setting a pusher cylinder and a pusher frame on the workbench, the pusher cylinder pushes the pusher frame between the hot pressing zone and the cooling zone, and the frame sleeve between the pusher frame and the shaping mold frame is used to automatically move the elastic grinding block to the cooling zone, avoiding the operator from contacting the high-temperature parts of the shaping mold frame and completely eliminating the risk of burns; the transfer time of the elastic grinding block between the hot pressing zone and the cooling zone is shortened to within 5 seconds, connecting to automated production and increasing the production capacity by more than 3 times.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0036] like Figure 1-6 As shown, an automatic hot pressing and cooling device for elastic modules is used to solve the problems of high manpower and low automation in the traditional production and processing of elastic abrasive blocks (a). This automatic hot pressing and cooling device for elastic abrasive blocks (a) includes a worktable 10 and a cooling system. The worktable 10 is divided into two working areas: a hot pressing zone 101 and a cooling zone 102, which are arranged side-by-side. The cooling system is located on the cooling chamber 102. A lifting pressure seat 20 is installed above the hot pressing zone 101. The raw material is first automatically fed into the shaping mold frame of the hot pressing zone, and then the lifting pressure seat 20 is driven by a hydraulic cylinder to press down and complete the hot pressing and forming of the elastic abrasive block (a).

[0037] The cooling system includes a cooling chamber and a water-cooled spray mechanism. The cooling chamber is integrated into the cooling area 102 of the workbench 10 and formed inside the workbench 10. The cooling chamber is specifically composed of circulating pipes. For example, a serpentine copper pipe is integrally cast inside the workbench 10. The total length and pipe diameter can be designed according to actual needs. The copper pipe is in direct contact with the workbench surface, resulting in better heat exchange efficiency than a separate cooling mold. Moreover, the integral molding avoids the risk of pipe leakage. Furthermore, the circulating pipes are arranged horizontally and vertically within the workbench 10, forming a rectangular array of strip-shaped pipe holes.

[0038] Both ends of the pipe are connected to a cooling water circulation system. By continuously circulating cold water into the circulation pipe, heat conduction and cooling are carried out on the shaping mold frame and elastic grinding block a on the cooling zone 102. For example, 5°C cold water is introduced at a flow rate of 2m / s to continuously remove heat from the table surface. Since the circulating cooling pipe 1021 is integrally formed on the worktable 10, the heat conduction effect on the worktable 10 is better.

[0039] The water-cooled spray mechanism is installed on the lifting pressure seat 20. As the lifting pressure seat 20 rises and falls, when the lifting pressure seat 20 moves above the cooling zone 102, the spray mechanism sprays the elastic grinding block a blank on the cooling zone 102 below, and together with the heat conduction cooling of the circulating cooling pipe 1021, it rapidly cools the elastic grinding block a.

[0040] Thus, in this embodiment, a cooling chamber is integrated into the workbench 10 and the corresponding cooling zone 102. Cold water is injected into the cooling chamber to conduct heat and cool the elastic grinding blocks a on the cooling zone 102. A water-cooling spray mechanism is set on the lifting pressure seat 20. Through the synergistic effect of the water-cooling spray and the heat conduction of the cooling chamber, the cooling time of each elastic grinding block a is shortened from the original 20 minutes to 5 minutes, avoiding the low efficiency and uneven cooling problems of manual handling and static cooling on the table. The synergistic effect of water-cooling spray and heat conduction improves the cooling uniformity, thereby enhancing the consistency of the hardness of the elastic grinding blocks a. Forced cooling ensures that the molding mold frame is completely cooled before recycling, preventing the formation of air holes caused by preheating and solidification of powder, avoiding affecting the molding quality of the elastic grinding blocks a, thereby improving the product yield and preventing customer products from being scratched or scrapped.

[0041] The water-cooled spray mechanism is positioned directly above the cooling zone 102 of the workbench 10 via a lifting pressure base 20. The water-cooled spray mechanism can optionally use a high-speed rotating aluminum alloy fan blade 30, or alternatively, a shower-shaped spray device. In this embodiment, the fan blade 30 is preferred. The fan blade 30 has a cylindrical cover around its perimeter, and a distribution pipe is installed inside the fan blade 30. Several spray outlet holes 301 with a diameter of 0.3mm-1mm are opened along the length of the bottom of the fan blade 30, preferably 0.5mm. Cooling water from the distribution pipe inside the fan blade 30 is sprayed outwards through the spray outlet holes 301.

[0042] When designing spray outlet holes 301 on the fan blades 30, the spray outlet holes 301 can be set on either an odd-numbered or even-numbered fan blades 30 arranged circumferentially, that is, the spray outlet holes 301 are set on the fan blades 30 alternately (for example, the 1st, 3rd, and 5th blades have spray outlet holes 301, while the 2nd, 4th, and 5th blades do not); or each fan blade 30 can have spray outlet holes 301. In this embodiment, the spray outlet holes 301 are preferably designed on the fan blades 30 alternately. Each blade has a number of spray outlet holes 301 evenly distributed along its length, and the spray outlet holes 301 are arranged in a single-row or double-row hole matrix spray net design at the bottom of the fan blades 30. In actual use, the design can be customized according to the usage requirements.

[0043] Therefore, by opening spray water outlet holes 301 on the alternating intervals of the fan blades 30, the alternating intervals avoid water mist overlap, optimize water mist distribution, and increase the coverage area by 35%; and the array hole design at the bottom of the fan blades 30 ensures uniform cooling, prevents local overcooling, and eliminates internal stress cracks in the elastic grinding block a.

[0044] When the fan blades 30 rotate at 1500 rpm inside the cylindrical cover, cooling water is delivered to the fan blade shaft or directly to each fan blade 30 via a pressurized pump, and sprayed downwards as a mist-like water curtain from the spray outlets 301. By designing the water-cooled spray mechanism as fan blades 30 with spray outlets 301, the cooling water is driven by the airflow of the fan blades 30 to be sprayed downwards as a mist-like water curtain from several spray outlets 301, covering the entire surface of the grinding block, thereby enhancing the cooling effect and increasing the vaporization heat absorption efficiency by 40%. Moreover, the atomized spray saves 50% more water than traditional water cooling, reducing water consumption.

[0045] The workbench 10 has a built-in water tank 40 with a certain volume on its base 60. The water stored in the tank 40 can be cooled by a condenser. A water pump connects the inlet of the circulating cooling pipe 1021 to the inlet of the spray outlet 301 of the fan blades 30. The sprayed water is filtered to remove impurities and then collected in the water tank 40. Water that undergoes heat conduction and temperature changes through the circulating cooling pipe 1021 can also be cooled by the condenser and returned to the water tank 40, forming a closed-loop cooling system. Therefore, through the circulating connection between the water tank 40, the circulating cooling pipe 1021, and the spray outlet 301 of the fan blades 30, water resources are recycled, reducing industrial water consumption. During use, the water temperature is stably controlled at 5±1℃, ensuring constant temperature cooling and consistent cooling performance.

[0046] The lifting pressure base 20 is connected to the workbench 10 via four hollow guide columns 21. The guide columns 21 have internal holes with pipes connecting to the water storage tank 40. The water-cooled spray mechanism is mounted on the lifting pressure base 20 via right-angled support arms 22, located above the cooling zone 102 of the workbench 10. The support arms 22 are also hollow and equipped with diversion pipes, which connect to the pipes inside the guide columns 21, thereby transporting cooling water from the water storage tank 40 to the water-cooled spray mechanism. Therefore, by designing the guide columns 21 for mounting the lifting pressure base 20 and the support arms 22 for mounting the water-cooled spray mechanism as hollow structures, the arrangement of cooling water pipes is facilitated, avoiding the pipe entanglement problem encountered when pipes are externally mounted, while ensuring smooth water supply to the water-cooled spray mechanism and improving equipment safety.

[0047] The worktable 10 is also equipped with a pusher cylinder 50. Specifically, the pusher cylinder 50 is installed horizontally on the side of the hot pressing zone 101, and its push rod is connected to the push frame 51. After hot pressing is completed, the lifting pressure seat 20 rises, and the pusher cylinder 50 pushes the push frame 51 to move the elastic grinding block a containing the shaping mold frame from the hot pressing zone 101 to the cooling zone 102. Therefore, by pushing the push frame 51 between the hot pressing zone 101 and the cooling zone 102 through the pusher cylinder 50, and by utilizing the frame sleeve cooperation between the push frame 51 and the shaping mold frame, the elastic grinding block a is automatically moved to the cooling zone 102. After cooling is completed, the elastic module a is taken out, and then the pusher cylinder 50 pulls the demolded shaping mold frame back to the hot pressing zone through the push frame 51, ready for the next automatic mold loading. Therefore, by avoiding operator contact with the high-temperature components of the molding frame, the risk of burns is completely eliminated; the transfer time of the elastic grinding block a between the hot pressing zone 101 and the cooling transfer zone is shortened to within 5 seconds, connecting to automated production and increasing production capacity by more than 3 times.

[0048] In addition, a feed port 511 is provided on the right side of the push frame 51, that is, the push frame 51 is designed as a U-shaped structure, since the width of the push frame 51 is designed to match the size of the shaping mold frame. Moreover, the opening of the feed port 511 has an inwardly sloping guide part, which is used to guide the shaping mold frame to quickly align and enter into the push frame 51, with a positioning error ≤0.5mm.

[0049] A feeding robot (not shown in the figure) is also installed on one side of the workbench 10. The feeding robot adopts a three-axis servo drive structure and has a vacuum suction cup at the end. The robot grabs raw materials from the raw material area and accurately puts them into the shaping mold frame through the feeding port 511. The single feeding cycle can be completed within 10 seconds. By replacing the traditional manual operation with the robot and the feeding system, an unmanned production line of "mold loading-hot pressing-cooling" is realized, which significantly reduces labor costs. The output of elastic grinding blocks a of a single machine has increased from 40 pieces / hour to 120 pieces / hour; and the automated production line reduces manpower by 80%, and the yield rate has increased from 82% to 98%, resulting in significant cost savings over the years.

[0050] The feeding robot automatically grabs and feeds materials. A photoelectric sensor is installed inside the feed inlet 511 to detect the signal that the robot has fed the material into place. The sensor is linked to the pushing program to achieve unattended operation.

[0051] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
