Description

Technical Field

[0001] The utility model relates to the technical field of coupling cover production, and particularly relates to a mold for producing a coupling cover. Background Technique

[0002] A coupling is a mechanical part used to connect two shafts (a driving shaft and a driven shaft) in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also have the functions of buffering, vibration reduction, and improving the dynamic performance of the shafting. A coupling consists of two halves, which are respectively connected to the driving shaft and the driven shaft. Generally, most prime movers are connected to the working machine with the help of a coupling. There are many types of couplings. When selecting, the appropriate type should be selected according to the working requirements first, then the torque and speed should be calculated according to the diameter of the shaft, and then the applicable model should be found from the relevant manuals. Finally, necessary calculations should be made for some key parts. The coupling mainly achieves torque transmission without backlash through pre-tightening. The shaft connection has no backlash, good flexibility and shock resistance, allows offsets in all directions, and even at high speeds, the movement is stable and can withstand a large workload. When producing a coupling, a mold is required to produce the coupling cover.

Square grooves are opened on the corresponding sides of the fixed iron blocks, and a left template and a right template are fixedly connected between the inner walls of the two square grooves. The left template is located on the left side of the right template. By setting the inclined tube, inclined groove, sliding groove, slider, sliding rod, rubber strip and processing template, the slider is moved, and the two side sliders move on the sliding rod, and the inclined tube slides out from the inclined groove, and by using the elastic effect of the rubber strip, the processing template can move up and down, and the processing template can move slightly up and down and is convenient to adjust, so as to facilitate the extrusion of waste from the inclined groove, which is convenient to use and does not affect the next processing, so that defective products are not easily produced and the work efficiency is improved;

[0004] However, the existing production molds are complex in structure and not easy to operate when producing a coupling cover. Moreover, when forming, it is not easy to eject and is prone to material jamming, which reduces the work efficiency during production. Content of the Utility Model

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides as Figures 1-4A mold for the production of a coupling cover is shown, including a workbench 1, brackets 2 provided at the four corners of the bottom surface, and vertical plates 3 fixedly connected to the top surface. A placement groove 4 capable of forming a shaping effect is opened inside the workbench 1. On one side of the surface of the vertical plate 3, a hydraulic cylinder 5 with a stamping effect is fixedly connected. On both sides of the placement groove 4 inside the workbench 1, trapezoidal ejector blocks 6 capable of automatically ejecting the coupling sleeve without jamming materials are provided. A collecting plate 7 capable of being pushed and pulled is provided at the bottom surface of the workbench 1. In the present utility model, the raw material is placed on the top surface of the placement groove 4. The output end of the hydraulic cylinder 5 drives the connecting rod 501 to make the stamping head 504 at the bottom press down on the raw material and enter the inside of the mold groove 401. The raw material is conveyed downward through the guiding blocks 402 provided on both sides. When the two sides of the raw material are bent into the shape of a cover, it will slide on the top surface of the trapezoidal ejector blocks 6 on both sides at the bottom, causing the trapezoidal ejector blocks 6 to displace. Finally, the shaped coupling cover falls onto the top surface of the buffer net 702, avoiding the problems of complex structures and material jamming in most devices, thereby improving production efficiency, reducing the risk of material jamming, and the simplicity during production and processing.

[0022] As Figures 1-3 shown, the placement groove 4 is opened inside the workbench 1. A mold groove 401 is opened inside the placement groove 4. On both sides of the inner wall of the mold groove 401, guiding blocks 402 are fixedly connected. Due to the trapezoidal design at both ends of the guiding blocks 402, when the raw material is being stamped and formed, the bending direction can be guaranteed. The two sides of the two guiding blocks 402 are both trapezoidally designed. The hydraulic cylinder 5 is fixedly connected to one side of the surface of the vertical plate 3. The output end of the hydraulic cylinder 5 is fixedly connected to a connecting rod 501. The bottom end of the connecting rod 501 is fixedly connected to a stamping head 504. The stamping head 504 can drive the raw material into the inside of the mold groove 401. A limiting groove 502 is opened at the bottom of the hydraulic cylinder 5 on the surface of the vertical plate 3. The inner wall of the limiting groove 502 is slidably connected to a limiting block 503. And one end of the limiting block 503 is fixedly connected to one side of the surface of the stamping head 504. The two trapezoidal ejector blocks 6 are both provided on both sides of the mold groove 401 inside the workbench 1. Working grooves 602 are opened on both sides inside the workbench 1. The inner walls of the two working grooves 602 are slidably connected to sliding blocks 603. And the bottom surfaces of the two sliding blocks 603 are respectively fixedly connected to the top surfaces of the two trapezoidal ejector blocks 6. Extension grooves 604 are opened at the bottoms of the two working grooves 602 inside the workbench 1. On the opposite sides of the inner walls of the two extension grooves 604, ejecting springs 605 are fixedly connected. The opposite ends of the two ejecting springs 605 are respectively fixedly connected to one end of the two trapezoidal ejector blocks 6. Due to the trapezoidal design of the top surface of the trapezoidal ejector block 6, the formed coupling cover will push open the trapezoidal ejector blocks 6 on both sides, and then keep moving downward until it finally lands on the top surface of the buffer net 702.

[0023] As Figure 1 and Figure 4As shown in the figure, the collection plate 7 is arranged on the bottom surface of the workbench 1. Fixed blocks 703 are fixedly connected to both sides of the bottom surface of the workbench 1. The setting of the fixed blocks 703 endows the collection plate 7 with the ability to be pushed and pulled, and the collection plate 7 is slidably connected to the inside of the two fixed blocks 703. A collection groove 701 is opened inside the collection plate 7, and buffer nets 702 are fixedly connected to the four sides of the inner wall of the collection groove 701. The design of the buffer nets 702 can prevent the formed coupling housing from falling to the ground, thus protecting the formed coupling housing.

[0024] The working principle of the present utility model: When the present utility model is in use, first place the raw material formed by stamping on the top surface of the placement groove 4, and then start the hydraulic cylinder 5. The output end of the hydraulic cylinder 5 drives the connecting rod 501 to move downward. While the connecting rod 501 moves downward, the stamping head 504 will press against the raw material located on the top surface of the placement groove 4 and enter the inside of the mold groove 401. When the stamping head 504 moves downward, the limiting block 503 will be used to slide in the limiting groove 502 for limiting;

[0025] When the stamping head 504 presses the raw material into the inside of the mold groove 401, first, the trapezoidal design on both sides of the guiding block 402 is used to bend the two ends of the raw material. When the bottom of the raw material contacts the trapezoidal ejector block 6, it will slide on the top surfaces of the two trapezoidal ejector blocks 6, so that the two trapezoidal ejector blocks 6 slide in the opposite direction by using the ejector springs 605. When moving to the bottom of the mold groove 401, it will be disengaged from the trapezoidal ejector block 6 and finally land on the top surface of the buffer net 702.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
