Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to a mold hardware processing device. Background Technology

[0002] Hardware molds generally refer to stamping molds, which are special process equipment used in cold stamping to process materials into parts or semi-finished products. They are called cold stamping molds.

[0003] When metal parts are stamped, fixtures are used to limit their movement to ensure stability during processing. However, due to the different applications of metal parts, the structure of the fixtures varies. Most fixtures are fixedly mounted on the processing table, which makes it inconvenient to adjust the fixture structure, thus increasing operating costs. Furthermore, a single processing table cannot select the structure of the fixture, which means that the fixtures on the processing table can only limit the movement of metal parts with a specific structure, thereby reducing the overall adaptability of the processing table. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the fixtures on the processing table in the prior art cannot limit the movement of hardware workpieces of different specifications, and to propose a mold hardware processing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mold hardware processing device includes a base and a processing head for processing hardware workpieces. A rotating rod is rotatably installed inside the base, and symmetrically arranged sliders are slidably sleeved on the rotating rod. Symmetrically arranged support rods are fixedly installed on the sliders, and clamping plates one and two for clamping the hardware workpieces are respectively fixedly installed on the two support rods. A cylinder is fixedly installed on the slider, and a connecting rod is connected between the output end of the cylinder and the two sliders. A clamping structure for clamping the rotating rod is installed on the base.

[0007] Preferably, the rotating rod is horizontally arranged, and a handle extending out of the base is fixedly installed on the rotating rod. A locking bolt corresponding to the base is threaded onto the handle. The base is equipped with a positioning block, and a cutting plate for intercepting iron filings is integrally connected to the positioning block.

[0008] Preferably, the first clamping plate is an arc-shaped structure adapted to the hardware workpiece, and the second clamping plate is a concave structure adapted to the hardware workpiece. Rubber pads that move and abut against the hardware workpiece are provided on the inner and outer surfaces of the first and second clamping plates. The support rod is vertically arranged at both ends of the slider, and the two ends of the connecting rod are respectively connected to the cylinder output end and the slider pin.

[0009] Preferably, the clamp structure includes a clamp block fixedly installed on the cylinder output end, a symmetrically arranged movable plate is slidably sleeved in the base, and a movable rod is integrally connected to the movable plate, and a frame extending to the clamp block is fixedly installed on the movable rod;

[0010] A rotating plate is fixedly installed on the rotating rod, a limiting rod extending into the rotating plate is slidably sleeved on the base, a guide frame connected to the limiting rod is slidably sleeved on the base, and a spring that cooperates with the guide frame is welded between the limiting rod and the base.

[0011] Preferably, the base has an elongated hole for guiding the movable plate, the frame and the movable rod extend to one side outside the base, the frame has a concave structure, and bolts connect the frame and the movable rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A mold hardware processing device includes a base 1 and a processing head 2 for processing hardware workpieces. The processing head 2 can process hardware workpieces after being powered on. This technical solution is existing technology and will not be elaborated on here.

[0023] A rotating rod 3 is rotatably installed inside the base 1. The rotating rod 3 is horizontally set, and a handle extending outside the base 1 is fixedly installed on the rotating rod 3. A locking bolt corresponding to the base 1 is threaded onto the handle. The rotating rod 3 is rotated by the handle, and the orientation of the first clamp 6 and the second clamp 7 can be adjusted when the rotating rod 3 rotates.

[0024] The base 1 is equipped with a positioning block, and a cut-off plate 19 for intercepting iron filings is integrally connected to the positioning block. To further explain, the positioning block is pushed onto the base 1 so that the cut-off plate 19 can intercept the opening of the base 1, thereby intercepting the iron filings generated during the processing of the hardware workpiece. A symmetrically arranged slider 4 is slidably sleeved on the rotating rod 3. A symmetrically arranged support rod 5 is fixedly installed on the slider 4, and a clamping plate 6 and a clamping plate 7 for clamping the hardware workpiece are fixedly installed on the two support rods 5 respectively. The rotating rod 3 guides the slider 4 so that the slider 4 can smoothly pull the support rod 5, clamping plate 6, and clamping plate 7 when moving.

[0025] A cylinder 9 is fixedly mounted on the slider 4, and a connecting rod 14 connects the output end of the cylinder 9 to the two sliders 4, according to the instruction manual. Figure 2 As shown, clamp 6 is an arc-shaped structure adapted to the hardware workpiece, and clamp 7 is a concave structure adapted to the hardware workpiece. Rubber pads 8 that move and abut against the hardware workpiece are provided on the inner and outer surfaces of clamp 6 and clamp 7. By setting clamp 6 to an arc-shaped structure adapted to the hardware workpiece and clamp 7 to a concave structure adapted to the hardware workpiece, the contact area between clamp 6 and clamp 7 and the hardware workpiece can be increased, thus ensuring the overall stability of the hardware workpiece after it is limited.

[0026] The support rod 5 is vertically positioned at both ends of the slider 4. The two ends of the connecting rod 14 are respectively connected to the output end of the cylinder 9 and the pin shaft of the slider 4. The rotating rod 3 is manually pulled to adjust the orientation of the clamping plate 1 6 and clamping plate 2 7. By adjusting the orientation of clamping plate 1 6 and clamping plate 2 7, the base 1 can clamp hardware workpieces of different specifications. To further explain, by extending and retracting the output end of the cylinder 9, clamping plate 1 6 and clamping plate 2 7 can clamp the outer surface of the hardware workpiece. By retracting the output end of the cylinder 9, clamping plate 1 6 and clamping plate 2 7 can clamp the inner surface of the hardware workpiece. This allows the base 1 to process the inner and outer surfaces of the hardware workpiece separately.

[0027] A clamping structure for clamping the rotating rod 3 is installed on the base 1.

[0028] The clamp structure includes a clamp block 10 fixedly installed on the output end of the cylinder 9, a symmetrically arranged movable plate 11 slidably sleeved inside the base 1, and a movable rod 12 integrally connected to the movable plate 11, and a frame 13 extending to the clamp block 10 fixedly installed on the movable rod 12.

[0029] The base 1 has an elongated hole for guiding the movable plate 11. The elongated hole guides the movable plate 11, which not only limits the movement direction of the movable rod 12 and the frame 13, but also ensures the stability of the slider 4 during movement. The frame 13 and the movable rod 12 extend to one side outside the base 1, and the frame 13 has a concave structure. The frame 13 and the movable rod 12 are connected by bolts.

[0030] A rotating plate 15 is fixedly installed on the rotating rod 3. A limiting rod 16 extending into the rotating plate 15 is slidably sleeved on the base 1. A guide frame 17 connected to the limiting rod 16 is slidably sleeved on the base 1. A spring 18 cooperating with the guide frame 17 is welded between the limiting rod 16 and the base 1. The rotating plate 15 is horizontally arranged on both sides of the rotating rod 3. The guide frame 17 has a T-shaped structure. The spring 18 is sleeved on the guide frame 17. The limiting rod 16 can extend into the rotating plate 15 through movement, thereby locking the position of the rotating plate 15 and the rotating rod 3. The spring 18 realizes the reset function of the limiting rod 16. When the guide frame 17 is in an unloaded state, the spring 18 can drive the limiting rod 16 back to the initial position.

[0031] The functional principle of this utility model can be explained through the following operation methods:

[0032] When it is necessary to process hardware workpieces with a ring-shaped structure;

[0033] The guide frame 17 is pulled out, so that the limiting rod 16 slides in the base 1. The traction handle drives the rotating rod 3 to rotate. When the rotating rod 3 rotates, the clamping plate 16 faces upward, so that the rotating plate 15 is in a horizontal state.

[0034] Release the traction on the guide frame 17, and under the action of the spring 18, the guide frame 17 will drive the limiting rod 16 to extend into the rotating plate 15, thereby initially limiting the rotating rod 3. Use the locking bolt to connect the handle and the base 1.

[0035] Pull the moving rod 12 to make the moving rod 12 drive the moving plate 11 to slide in the elongated hole. The moving rod 12 drives the frame 13 to extend onto the locking block 10. Use bolts to connect the frame 13 and the moving rod 12.

[0036] The output ends of the two cylinders 9 extend and retract, causing the two clamping blocks 10 to move in opposite directions. When the output ends of the cylinders 9 move, the traction connecting rod 14 deflects. The position difference generated by the connecting rod 14 during deflection can pull the slider 4, causing the two sliders 4 to slide on the rotating rod 3 and drive the two clamping plates 6 to move closer to each other. The two clamping plates 6 drive the rubber pads 8 to clamp the hardware workpiece from both sides.

[0037] The positioning block is pushed onto the base 1 so that the two sections 19 seal the opening of the base 1. After the processing head 2 is powered on, it processes the inner wall of the hardware workpiece.

[0038] When it is necessary to process plate-shaped hardware workpieces, the rotation of the rotating rod 3 causes the clamping plate 2 7 to face upwards. The above steps are repeated to clamp the rotating rod 3, so that the processing head 2 can process the inner wall of the plate-shaped hardware workpiece.

[0039] When the outer surface of the hardware workpiece needs to be processed, the two sliders 4 approach each other, so that the outer surface of the clamping plate 6 or the clamping plate 7 can move against the inner wall of the hardware workpiece. The output end of the cylinder 9 retracts, so that the clamping plate 6 or the clamping plate 7 can clamp the hardware workpiece from the inside. Then, the processing head 2 can process the outer surface of the hardware workpiece.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
