This invention discloses a front-end processing device for instrument manufacturing, relating to the field of instrument production and processing technology. It includes a processing table with a stamping assembly fixedly mounted on its top. In use, the heating wire is activated to heat the wax coating agent into liquid wax. An electric actuator is activated, sequentially pushing a fixed plate, a forward / reverse motor, and four corner blocks upwards. A support plate and connecting rod then push an arc-shaped tube to move, causing the fixed tube and nozzle to move into the stamping die.

Description

Technical Field

[0001] This invention relates to the field of instrument manufacturing technology, specifically to a front-end processing device for instrument manufacturing. Background Technology

[0002] Instruments and meters are devices used to measure, control, monitor, and display physical quantities or parameters. They are widely used in various industries, including industrial production, laboratory research, and medical diagnostics. The pre-processing in instrument manufacturing refers to the initial processing and treatment of raw materials during the manufacturing process to prepare the parts and components needed for manufacturing the instruments and meters. Stamping is a common method in this pre-processing stage, generally used to manufacture parts such as housings, panels, and connectors. It involves applying pressure to a sheet metal to press it into the desired shape.

[0003] In the prior art, the front-end processing device for instrument manufacturing presses the raw material into the mold through the stamping head to form the instrument housing. However, the raw material will frequently rub against the inner wall of the mold during the stamping process, which will cause damage to the inner wall of the mold and introduce undesirable surface defects such as scratches and grooves, thereby reducing the surface quality of the stamped parts. Due to the damage to the inner wall of the mold, more frequent mold repair or replacement is required, which will increase the production cost.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In use, the heating element is activated to heat the heating barrel, turning the wax coating into liquid wax. The electric actuator is activated, sequentially pushing the fixed plate, forward and reverse motors, and four corner blocks upward. The support plate and connecting rod push the arc-shaped tube to move, causing the fixed tube and nozzle to slide out of the moving hole and move into the stamping die. The spraying pump is activated, pumping the liquid wax coating into the hose through the pumping pipe. The wax coating enters the arc-shaped tube and multiple fixed tubes in sequence, where it is sprayed by the nozzle. The servo motor is activated, driving the drive wheel to rotate, which in turn drives the driven wheel and stamping seat to rotate, and then drives the stamping die to rotate, resulting in uniform spraying and forming a smooth protective layer with a certain hardness. This reduces the coefficient of friction and wear, thereby achieving a protective effect.

[0019] 2. When using this invention, after the wax coating is sprayed, the excess wax coating flows down the inner wall of the stamping mold, flows through the flow hole into the liquid guide tube, and then falls into the liquid collection pull box for collection. The liquid collection pull box can be taken out from the pull hole by unscrewing the hand-tightening bolt on the outside of the liquid collection pull box, which facilitates the collection and reuse of the wax coating. Under the protection of the protective cover, the hose is prevented from accidentally getting tangled in other equipment. Under the heat preservation effect of the heat insulation pad, the wax coating is kept warm, which facilitates better flow.

[0020] 3. When using this invention, the starting cylinder pushes the installation downwards, causing the stamping block to move downwards for stamping. The forward and reverse motors are started, causing the four corner blocks to rotate and remain parallel to the four corner holes. The electric push rod is started, pushing the fixing plate and the forward and reverse motors through the four corner holes, while simultaneously driving the four corner blocks to push the ejector rod and ejector plate upwards, ejecting the stamped material for easy removal by the staff. The heating chamber is weighed using a weighing scale. When the weight changes and gradually approaches the original weight, it indicates that the wax coating agent inside the heating chamber is insufficient, allowing the staff to replenish it in time.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9As shown, the present invention provides a technical solution: a front-end processing device for instrument manufacturing, comprising: a processing table 1, a stamping assembly 2 fixedly mounted on the top of the processing table 1, a movable hole 7 opened at the center of the top of the processing table 1, a stamping seat 3 movably embedded inside the movable hole 7, a mounting groove 15 opened on the top of the stamping seat 3, and a stamping die 9 disposed inside the mounting groove 15; and a spraying assembly 4, comprising a heating box 401, a heating barrel 406 fixedly mounted inside the heating box 401 near one side, and the heating barrel 406 near the bottom. The outer surface of the part is provided with an electric heating wire 407. A spray pump 403 is fixedly installed on the top of the heating box 401. The input end of the spray pump 403 is connected to a pumping pipe 413 through a flange. The output end of the spray pump 403 is connected to a hose 409 through a flange. One end of the hose 409 is fixedly connected to an arc-shaped pipe 416. Multiple fixed pipes 417 are fixedly installed on the outer surface of the arc-shaped pipe 416. Two nozzles 418 are fixedly connected to the outer surface of each of the multiple fixed pipes 417. Limiting plates 419 are fixedly installed at the top of each of the multiple fixed pipes 417.

[0033] At the same time, according to Figures 8-9 As shown, the bottom surface of the stamping die 9 is provided with multiple embedded grooves 11, and the bottom surface of each embedded groove 11 is provided with a moving hole 18. The outer surfaces of multiple limiting plates 419 are respectively movably embedded in the multiple embedded grooves 11. The outer surfaces of multiple fixed tubes 417 near the top are respectively movably embedded in the multiple moving holes 18. The outer surface of the arc-shaped tube 416 is movably embedded in the stamping seat 3. The embedded grooves 11 facilitate the embedding of the limiting plates 419, which are flush with the bottom surface of the stamping die 9, without affecting the stamping of the raw materials. The moving holes 18 facilitate the up and down movement of the fixed tubes 417 and the nozzles 418, without affecting the subsequent rotation of the stamping die 9.

[0034] according to Figures 3-7 and Figure 9 As shown, an electric push rod 404 is fixedly installed on the other outer surface of the heating box 401 via an auxiliary plate. A fixing plate 410 is fixedly installed on the top of the electric push rod 404. A forward and reverse motor 411 is fixedly installed on the top of the fixing plate 410. A four-corner locking block 420 is fixedly installed at the output end of the forward and reverse motor 411. Multiple connecting rods 405 are fixedly installed on the outer surface of the arc-shaped tube 416 away from the fixing tube 417. A support plate 412 is fixedly connected to the bottom end of the multiple connecting rods 405. The outer surface of the four-corner locking block 420 is movably embedded inside the support plate 412. By activating the electric push rod 404, the fixing plate 410 and the forward and reverse motor 411 at the top are pushed upward, which then drives the four-corner locking block 420 to move and drives the support plate 412 to move upward. Under the connection of the connecting rods 405, the arc-shaped tube 416 is pushed upward, causing the fixing tube 417 to slide upward, which drives multiple nozzles 418 to slide out from the moving hole 18 and move into the stamping mold 9 for subsequent spraying.

[0035] according to Figures 6-9 As shown, the top surface of the support plate 412 has four corner locking holes 423, and the bottom surface of the support plate 412 has a circular hole. The output end of the forward and reverse motor 411 extends through the interior of the support plate 412. A push rod 421 is fixedly installed at the center of the top of the four corner locking blocks 420, and a push plate 422 is fixedly installed at the top of the push rod 421. A push groove 12 is provided at the center of the bottom surface of the stamping die 9, and the outer surface of the push plate 422 is movably embedded in the push groove 12. The push rod... The top of 421 extends into the interior of the top material groove 12. By starting the forward and reverse motor 411, the four corner blocks 420 are rotated and kept parallel to the four corner holes 423. The electric push rod 404 is started, which pushes the fixed plate 410 and the forward and reverse motor 411 to move upward and pass through the circular hole and the four corner holes 423. Then, the four corner blocks 420 and the top material rod 421 are pushed upward, so that the top material plate 422 slides out of the top material groove 12 and pushes out the stamped material, making it convenient for the staff to pick up the material.

[0036] according to Figure 3 and Figure 8 As shown, a rotating assembly 8 is fixedly installed on one side inside the processing table 1. The rotating assembly 8 includes a reinforcing plate 801. A servo motor 802 is fixedly installed on the top of the reinforcing plate 801. A drive wheel 803 is fixedly installed at the output end of the servo motor 802. A driven wheel 804 is meshed with the outer surface of the drive wheel 803. The inner wall of the driven wheel 804 is fixedly installed on the outer surface of the stamping base 3 near the bottom. The outer surface of the reinforcing plate 801 is fixedly installed on one side inside the processing table 1. By starting the servo motor 802, the drive wheel 803 is driven to rotate, which in turn drives the driven wheel 804 to rotate. This, in turn, drives the stamping base 3 and the stamping die 9 to rotate, so that the wax coating can be evenly and completely sprayed onto the inner wall of the stamping die 9, forming a uniform protective film on the entire stamping area and improving the protective effect.

[0037] according to Figure 1 and Figures 8-9As shown, a PLC controller 6 is fixedly installed on the outer surface of the processing table 1. Multiple flow holes 13 are opened at the edge of the bottom surface of the stamping die 9. Liquid guide pipes 14 are fixedly connected to the bottom of the stamping die 9 near the multiple flow holes 13. The outer surface of the stamping die 9 is in contact with the inner wall of the mounting groove 15. Multiple pull holes 16 are opened on the outer surface of the stamping base 3 near the top. Liquid collection pull boxes 17 are movably embedded inside the multiple pull holes 16. The outer surfaces of the multiple liquid collection pull boxes 17 are all installed on the outer surface of the stamping base 3 by hand-tightening bolts. The PLC controller 6 can control the opening and closing of other equipment. The wax coating agent flows into the liquid guide pipe 14 through the flow holes 13 on the side and then falls into the liquid collection pull box 17 for collection. By unscrewing the hand-tightening bolts, the liquid collection pull box 17 can be taken out from the pull hole 16, which facilitates the collection and reuse of the wax coating agent in the liquid collection pull box 17.

[0038] according to Figure 1 and Figures 3-5 As shown, a weighing scale 5 is installed at the bottom of the heating chamber 401, and the bottom of the weighing scale 5 is in contact with the bottom of the processing table 1. A threaded cover 408 is threaded onto the top of the heating barrel 406, and an exhaust hole is opened on the top of the threaded cover 408. The top of the heating barrel 406 is fixedly connected to the top of the heating chamber 401, and the bottom of the spray pump 403 is movable and connected to the interior of the heating chamber 401. The weighing scale 5 can be used to weigh the heating chamber 401 first, and then weigh the heating chamber 401 after the wax coating agent is added. As the wax coating agent gradually decreases, the weight measured by the weighing scale 5 will change. When the weight detected by the weighing scale 5 gradually approaches the original weight, it indicates that the wax coating agent in the heating barrel 406 is insufficient, which is convenient for the staff to replenish in time.

[0039] according to Figure 5 As shown, one end of the extraction pipe 413 is fixedly inserted into the interior of the heating tank 406, and one end of the flexible hose 409 is movably inserted into the top of the heating box 401. A protective cover 414 is provided on the outer surface of the flexible hose 409, and a heat insulation pad 415 is fixedly connected to the inner wall of the protective cover 414. When the flexible hose 409 moves up and down, it is easier for the flexible hose 409 to move up and down better under the protection of the protective cover 414, preventing the flexible hose 409 from accidentally getting tangled in other equipment and affecting the normal movement of the arc-shaped pipe 416. At the same time, the heat insulation pad 415 keeps the wax coating in the flexible hose 409 warm, which facilitates its better flow.

[0040] according to Figure 1 and Figures 3-5The bottom of the protective cover 414 shown is fixedly installed on the top of the heating box 401 near the other side. The front surface of the processing table 1 is connected to the movable door 10 by a hinge. The front surface of the heating box 401 is installed with a maintenance door 402 by screws. The movable door 10 can be opened by unscrewing the fixing bolts on the front surface of the movable door 10, which facilitates the maintenance of the equipment inside the processing table 1. The wax coating can be replenished or the equipment can be maintained by opening the maintenance door 402.

[0041] according to Figure 2 As shown, the stamping assembly 2 includes a stamping frame 201. A cylinder 202 is fixedly installed on the top surface inside the stamping frame 201. An mounting plate 203 is fixedly installed on the output end of the cylinder 202. A stamping block 204 is provided at the bottom of the mounting plate 203. Positioning rods 205 are fixedly installed on the top of the mounting plate 203 near both sides. The top ends of the two positioning rods 205 extend movably through to the top of the stamping frame 201. The bottom of the stamping frame 201 is fixedly installed on the top of the processing table 1. By activating the cylinder 202, the mounting plate 203 is pushed downward. Under the action of the two positioning rods 205, the accuracy of the stamping block 204 is improved. The movement of the mounting plate 203 drives the stamping block 204 to move into the stamping die 9 to stamp the raw material.

[0042] The overall effect and working principle of the mechanism are as follows: When in use, the cylinder 202, spray pump 403, electric push rod 404, heating wire 407, forward and reverse motor 411, weight scale 5, servo motor 802 and PLC controller 6 are electrically connected. Multiple limit plates 419 are embedded in the inner groove 11, and the top plate 422 is embedded in the top groove 12. The tops of the limit plates 419 and the top plate 422 are flush with the bottom surface of the stamping die 9, which does not affect the stamping of the raw material. The circular hole at the bottom of the support plate 412 is relatively large, which facilitates the forward and reverse motor 411 to move up and down through the circular hole and the four corner locking holes 423. The threaded cover 408 is opened in advance, and wax coating agent is put into the heating barrel 406. The four corner locking blocks 420 are embedded in the support plate 412. The positions of the four corner locking blocks 420 and the four corner locking holes 423 are staggered. Figure 7As shown, when the four corner blocks 420 move, they drive the support plate 412 to move. The PLC controller 6 activates the heating wire 407 to generate heat, which heats the heating barrel 406, thereby heating the wax coating and turning it into liquid wax. At the same time, the electric actuator 404 is activated, pushing the fixed plate 410 and the top forward and reverse motor 411 upward. This then drives the four corner blocks 420 to move, and the support plate 412 to move upward. With the connection of the connecting rod 405, the arc-shaped tube 416 is pushed upward into the stamping seat 3, so that the corresponding fixed tube 416... 17 slides upward in the corresponding moving hole 18, causing the corresponding limiting plate 419 to slide out of the inner groove 11. At the same time, multiple nozzles 418 slide out from the moving hole 18 and move into the stamping die 9. At this time, the electric push rod 404 pauses for a period of time. The hose 409 is provided with a certain length to facilitate the up and down movement with the arc tube 416. One end of the pumping pipe 413 extends into the heating tank 406 near the bottom surface to facilitate the pumping pipe 413 to pump the liquid wax coating. When the wax coating is heated and turns into a liquid, the spraying pump 403 is started, and the liquid wax coating is pumped through the pumping pipe 413. The wax is pumped into the hose 409, then into the arc-shaped tube 416, and then into the interior of multiple fixed tubes 417. Multiple nozzles 418 spray the wax coating onto the inner wall of the stamping die 9. The spray pump 403 automatically stops after operating for a period of time. When the spray pump 403 stops spraying, the electric actuator 404 resumes operation, pulling the fixed plate 410, the forward and reverse motors 411, the four corner blocks 420, and the support plate 412 downwards. This further drives the arc-shaped tube 416, the fixed tubes 417, and the limiting plate 419 to reset. After a period of time, the wax coating on the inner wall of the stamping die 9 is sprayed onto the inner wall. The applied wax coating cools and solidifies, forming a smooth and relatively hard protective layer on the inner wall of the stamping die 9. This reduces the coefficient of friction between the raw material and the inner wall of the stamping die 9 during the stamping process, protecting the stamping die 9 and reducing wear, thus achieving a protective effect. Simultaneously with the wax coating application, the servo motor 802 is activated. The rotation of the output end of the servo motor 802 drives the drive wheel 803 to rotate, causing the driven wheel 804, which is meshed with it, to rotate. This, in turn, drives the stamping base 3 to rotate. The top of the stamping die 9 is bolted to the top of the stamping base 3. Figure 9As shown, when the stamping base 3 rotates, it drives the stamping die 9 to rotate, allowing the wax coating agent to be evenly and completely sprayed onto the inner wall of the stamping die 9, forming a uniform protective film on the entire stamping area, improving the protective effect. With the cooperation of the spraying component 4 and the rotating component 8, uniform spraying of the wax coating agent is achieved, effectively reducing damage to the inner wall of the die and eliminating the need for frequent repairs or replacements. This solves the problem that during the front-end stamping process in instrument manufacturing, the raw materials frequently rub against the inner wall of the die, causing damage to the inner wall of the die, reducing the surface quality of the stamped parts, and requiring frequent repairs or replacements of the die, thus increasing production costs. When the spraying is completed, the servo motor 802 stops operating. At this time, the multiple liquid guide pipes 14 are located above the multiple liquid collection pull boxes 17. Afterwards, excess wax coating flows downwards along the inner wall of the stamping die 9, through the side flow hole 13 into the liquid guide tube 14, and finally falls into the collection box 17. The collection box 17 collects the wax coating, reducing waste and preventing it from forming clumps on the bottom surface of the stamping die 9, which would affect the stamping effect. The collection box 17 is fixed to the outer surface of the stamping base 3 by a hand-tightening bolt to prevent it from accidentally sliding out when the stamping base 3 rotates. By unscrewing the hand-tightening bolt, the collection box 17 can be removed from the pull hole 16, facilitating the collection and reuse of the wax coating. When the hose 409 moves up and down, it is protected by the protective cover 414, allowing the hose 409 to move more smoothly. The system moves up and down to prevent the hose 409 from accidentally getting tangled in other equipment and affecting the normal movement of the arc-shaped tube 416. Simultaneously, the insulation pad 415 keeps the wax coating in the hose 409 warm, facilitating its flow. Once the wax coating on the inner wall of the stamping die 9 has solidified, the cylinder 202 is activated, pushing the mounting plate 203 downwards. The two positioning rods 205 improve the accuracy of the stamping block 204. The movement of the mounting plate 203 drives the stamping block 204 into the stamping die 9 to stamp the raw material. When the cylinder 202 pulls the stamping block 204 back to its original position, the forward and reverse motor 411 is activated. The output of the forward and reverse motor 411 drives the four corner clamps 420 to rotate, keeping them parallel to the four corner clamp holes 423. In the next step, the electric actuator 404 is activated, pushing the fixed plate 410 and the forward / reverse motor 411 upward. Then, the four corner blocks 420 are pushed through the four corner locking holes 423. At this time, the forward / reverse motor 411 and the bottom fixed plate 410 pass through the circular hole and the four corner locking holes 423 in sequence. The movement of the four corner blocks 420 pushes the ejector rod 421 upward, causing the ejector plate 422 to slide out of the ejector groove 12, thereby ejecting the stamped material from the stamping die 9, achieving the effect of ejecting the material. This makes it convenient for workers to retrieve the material. The weighing scale 5 can be used to weigh the heating box 401 first, and then weigh the heating box 401 after the wax coating has been added. As the wax coating gradually decreases, the weight measured by the weighing scale 5 will change.When the weight measured by scale 5 gradually approaches the original weight, it indicates that the wax coating inside heating tank 406 is insufficient, allowing staff to replenish it promptly.

[0043] Among them, cylinder 202, spray pump 403, electric actuator 404, heating wire 407, forward and reverse motor 411, weight scale 5, servo motor 802 and PLC controller 6 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
