Description

Technical Field

[0001] This utility model relates to the field of metal stamping, specifically to an instrument housing processing device. Background Technology

[0002] Instrument housings, as one of the most common housing structures, such as pressure gauges, routers, small metal lamps, and radiator metal housings, involve the following processing steps:

[0003] Cutting: Cutting metal sheets into suitable shapes;

[0004] Turning and milling improve the surface quality of sheet metal and process it into the desired shape and size;

[0005] Drilling: Drilling holes in the shell according to design requirements;

[0006] Stamping is the process of using stamping equipment and dies to stamp features such as holes, slots, protrusions, and cylinders onto sheet metal parts.

[0007] Surface treatment, including surface treatments such as spraying.

[0008] When stamping metal sheets or sheet metal parts, the metal sheets or sheet metal parts need to be placed under the stamping head, and the stamping die is used to stamp the metal sheets or sheet metal parts into shape. Currently, automatic feeding devices are generally used when placing the metal sheets or sheet metal parts to be stamped. For example, a hydraulic structure is used to push the metal sheets or sheet metal parts into the die under the stamping head to realize the stamping process. However, when unloading, it is necessary to unload separately. The unloading can be done manually or by using a suction cup structure to pick up the sheet metal parts from the die. The feeding and unloading use two independent automated systems, which are relatively complex in structure and need to be controlled independently, making the control more difficult. Utility Model Content

[0009] The purpose of this utility model is to provide an instrument housing processing device to solve the problems mentioned in the background art.

[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an instrument housing processing device, comprising:

[0011] The main body has a punching head mounted on its upper part, and an upper mold is mounted on the movable end of the punching head, which is used to move the upper mold up and down.

[0012] The worktable is located directly below the stamping head, and the lower die is installed on its upper part;

[0013] The rotating disk is mounted on the worktable. The bottom surface of the rotating disk is in contact with the upper surface of the lower mold. The rotating disk has multiple placement openings for placing metal sheets. When the rotating disk rotates, it can carry the metal sheets placed in the placement openings to overlap with the lower mold.

[0014] Preferably, a support ring is fixedly installed on the worktable, and a rotating disk is rotatably installed on top of the support ring.

[0015] Preferably, a rotating shaft is fixedly installed on the central axis of the rotating disk, and a motor is installed at the bottom end of the rotating shaft. The motor is fixedly installed inside the worktable and is used to rotate the rotating shaft and the rotating disk.

[0020] Eddy current coils are located inside the housing;

[0021] An opening is formed on the side wall of the housing and is coaxially arranged with the housing. When the rotating disk rotates, it can carry the metal piece at the placement opening into the opening.

[0022] The eddy current coil has a wide slit at the opening position, allowing the metal sheet at the opening to enter the interior of the eddy current coil through the wide slit, thereby heating the metal sheet.

[0023] Preferably, the lower mold is a cylindrical structure with an open top, and a bottom template is slidably installed inside it. A spring is fixedly installed between the bottom template and the bottom of the inner cavity of the lower mold.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] This utility model features a rotating disk with a placement opening. A spring on the lower mold pushes out the stamped parts, with the bottom of the pushed-out parts still in the placement opening. When the rotating disk rotates to feed the parts, it can move the stamped parts located at the placement opening away from directly below the stamping head. This single structure can simultaneously realize the feeding and unloading of parts, making the structure simpler and easier to control. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please refer to the figure. This embodiment discloses an instrument housing processing apparatus, including:

[0038] The main body 1, with a structure referencing the MA4132 punch press, has a hydraulic punch head 2 mounted on its upper part. Specifically, a hydraulic rod is fixedly mounted on the upper end of the main body 1, and the punch head 2 is the telescopic end of the hydraulic rod. The movable end of the punch head 2 is bolted to a top die. See Figure 1- for details. Figure 3 As shown.

[0039] The worktable is fixedly installed at the bottom of the main body 1, and is located directly below the stamping head 2. The lower die 3 is fixedly installed on the upper surface of the worktable by bolts. Figure 3 and Figure 4 As shown, the lower mold 3 is a cavity structure with an open top. The shape of the cavity can be customized according to the shape of the product to be stamped. For example, the shape of a pressure gauge is cylindrical, and the cavity of the lower mold is also cylindrical.

[0040] A rotating disk 5 is mounted on a worktable with a support ring 4 fixedly installed. The top of the rotating disk 5 is rotatably connected to the support ring 4, allowing the rotating disk 5 to rotate around its axis at the upper end of the support ring 4. The bottom surface of the rotating disk 5 is in contact with the upper surface of the lower mold 3, but they are not connected. The lower mold 3 provides support for the rotating disk 5. Figures 1-3 As shown, the rotating disk 5 has multiple placement openings 6, which are arranged in a ring around the center of the rotating disk 5. The placement openings 6 are used to place the metal sheets to be stamped. When the rotating disk 5 rotates, it carries the metal sheets from the placement openings 6 to overlap with the lower mold.

[0041] During feeding, the material can be fed into the placement port 6, which is far away from the stamping head. By setting up the rotating disk 5, the metal sheet can be continuously and uninterruptedly fed onto the rotating disk 5, which can improve processing efficiency. Moreover, the feeding part is far away from the stamping head 2, making feeding safer.

[0042] 0041 In this embodiment, the rotational power of the rotating disk 5 is provided by a servo motor. A rotating shaft 8 is fixedly installed at the center of the rotating disk 5. The housing of the servo motor is fixedly installed on the worktable, and its output end is fixedly connected to the rotating shaft 8 to rotate the rotating shaft 8 and the rotating disk 5. The servo motor can control speed and has very accurate position. It can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft, and can control the rotation of the motor very precisely, thereby achieving precise positioning, which can reach 0.001mm. The servo motor is a mature technology and can be directly purchased from the market.

[0043] like Figures 1-3 As shown, there are 4 placement ports 6. After aligning the first placement port 6 with the lower mold 3, the servo motor drives the rotating disk 5 to rotate 90 degrees, so that the metal sheet on the placement port 6 can overlap with the lower mold 3.

[0044] To better control the rotation speed of the rotating disk 5, a gear reducer can also be installed between the output end of the servo motor and the rotating shaft 8. For example, a two-stage gear reducer (which can be purchased directly from the market and is an existing technology) can be used. The input shaft of the reducer is fixedly connected to the output end of the servo motor, and the output shaft of the reducer is fixedly connected to the rotating shaft 8. It can rotate the rotating shaft 8 and the rotating disk 5. The use of reducers is very mature and will not be elaborated here.

[0045] In this embodiment, the placement port 6 includes a recess and a through port. The structure of the recess can be designed as a circle, rectangle, polygon or irregular shape according to the shape of the metal sheet to be processed. In this embodiment, a circle is used as an example. The recess is used to place the metal sheet to be stamped.

[0046] The through-hole and the recess are coaxially aligned, and the diameter of the through-hole is the same as the opening diameter of the lower mold 3. When the rotating disk rotates, it carries the metal sheet from the placement port to coincide with the lower mold. When the placement port 6 rotates to be directly above the lower mold 3 and coincides with it, the axis of the through-hole and the opening of the lower mold 3 coincides, and the rotating disk 5 is in contact with the upper end face of the lower mold 3. When the upper mold moves downwards with the stamping head 2, the upper mold acts on the lower metal sheet and presses the metal sheet from the through-hole and the opening into the cavity of the lower mold 3, thereby forming the metal sheet. In this embodiment, since the rotating disk 5 is in contact with the upper end face of the lower mold 3, the lower mold 3 provides support for the rotating disk 5, preventing damage to the rotating disk 5 when the stamping head 2 provides pressure.

[0047] In this embodiment, a heating element is provided to better achieve the stamping of the metal sheet, enabling hot pressing of the metal sheet. Specifically, as shown... Figure 1 , Figure 3 and Figure 6 As shown, the heating part includes a housing 7, which is made of a highly conductive ceramic material. The bottom of the housing 7 is detachably mounted on the rear side of the worktable of the main body 1 by bolts.

[0048] Eddy current coil 12 is fixedly installed inside housing 7. Eddy current coil 12 is powered by an external power source (a transformer can be added, which is existing technology and will not be described in detail here).

[0049] Opening 9 is formed on the side wall of housing 7 and is coaxially arranged with housing 7, such as... Figure 3 and Figure 6As shown, the eddy current coil 12 has a wide slit at the opening 9. When the rotating disk 5 rotates, the metal sheet at the placement opening 6 can enter the opening 9 and then enter the interior of the eddy current coil 12 through the wide slit, thereby heating the metal sheet. The upper and lower surfaces of the rotating disk 5 are almost in contact with the sidewalls of the opening 9, essentially sealing the opening 9 and achieving heating of the metal sheet. Along the direction of rotation of the rotating disk 5, the lower mold 3 and the housing 7 are positioned adjacent to each other, with the housing 7 located behind the lower mold 3. Figure 1 and Figure 3 As shown. When one of the metal sheets rotates and coincides with the lower mold 3, the adjacent metal sheet on the rear side of the metal sheet is located in the housing 7, and the eddy current coil 12 heats the rear metal sheet.

[0050] Furthermore, since the housing 7 is located close to the lower mold, after the metal sheet is heated, the metal sheet can rotate a short distance to overlap with the lower mold for stamping, which can reduce the heat dissipation of the metal sheet.

[0051] After stamping is completed, in order to facilitate the stamped part to come out of the lower die, such as Figure 4 and Figure 5 As shown, a bottom template 11 is slidably installed inside the lower mold 3. A spring 10 is fixedly installed between the bottom template 11 and the bottom of the inner cavity of the lower mold 3. The top of the spring 10 is fixedly connected to the bottom template 11, and the bottom is fixedly connected to the bottom of the inner cavity of the lower mold 3. A space for storing the spring 10 is provided at the bottom of the inner cavity of the lower mold 3. When the bottom template 11 is at the bottom of the lower mold 3, the spring 10 is compressed into this space. Figure 5 As shown. After stamping is completed, spring 10 provides an upward elastic force to the stamped part. When the upper die moves upward and the pressure disappears, the stamped part is pushed out of the lower die 3 under the elastic force of spring 10 until the bottom die plate 11 is flush with the opening of the lower die 3, as shown. Figure 5 As shown, the stamped parts come out completely from the lower mold. However, at this time, the bottom of the mold is located in the through-hole of the placement port 6. As the rotating disk 5 rotates, the placement port 6 will carry the stamped parts away from directly below the stamping head 2. When the rotating disk 5 rotates, it simultaneously realizes the overlap of the metal sheet to be stamped with the lower mold 3, realizing the synchronous coordination of material picking and unloading.

[0052] The stamped parts come out completely from the lower die and can be removed directly. During stamping, stamping oil is usually applied to the die, which has a lubricating effect. Therefore, most parts will separate from the upper die under their own weight and fall into the lower die 3. Therefore, a discharge spring 10 is set in the lower die 3. A very small number of parts may stick to the upper die. This situation is relatively rare. If it occurs, the parts can be manually removed from the upper die.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
