Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a mechanical processing equipment with a protection mechanism. Background Art

[0002] Machining is a processing process, which refers to the process in which mechanical equipment changes the shape, size or performance of a workpiece, and the equipment that completes such operations is called machining equipment. At present, according to the processing method, machining equipment is roughly divided into cutting equipment and pressure processing equipment. Common pressure processing equipment includes stamping devices, etc.

[0003] When the stamping device is in use, the workpiece will be placed on the lower die first, and then the lifting mechanism located above will push the upper die closer to the lower die and complete the stamping operation of the workpiece. However, most of the current stamping devices will produce a certain impact when the upper and lower dies contact, and because the pressure generated by the upper die when it is pressed down by the lifting mechanism will be very large, the impact effect when the upper and lower dies contact is also large. Under frequent use, it is easy to cause damage to the upper and lower dies, affecting the life of the dies. To this end, we propose a mechanical processing equipment with a protective mechanism to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a mechanical processing equipment with a protective mechanism, comprising a base 1, a rectangular groove 4 is opened on the top of the base 1, and a lower mold 2 is arranged in the rectangular groove 4;

[0022] A top plate 6 is arranged parallel to the top of the base 1, and support rods 5 are vertically installed at the bottom corners of the top plate 6. The bottom of the support rods 5 is fixed correspondingly to the bottom corners of the rectangular groove 4, and a buffer is installed on each support rod 5. A first support plate 7 is arranged between the top plate 6 and the base 1. The first support plate 7 is parallel to the top plate 6, and the support rods 5 slide through the first support plate 7. An upper mold 3 corresponding to the lower mold 2 is installed at the bottom of the first support plate 7. The sliding of the first support plate 7 on the support rods 5 provides a guide for the lifting and lowering of the first support plate 7, and the buffer acts as a buffer during the pressing process of the upper mold 3, so as to avoid collision due to excessive impact when the upper mold 3 contacts the lower mold 2, thereby causing damage to the two molds.

[0023] Second connecting rods 15 are arranged in parallel on both sides above the first support plate 7, and second fixing plates 16 are installed at the ends of the second connecting rods 15, and the second fixing plates 16 are fixed on the first support plate 7. A second compression spring 27 is sleeved on one end of the second connecting rod 15 close to the second fixing plate 16, and a U-shaped plate 9 is arranged above the first support plate 7, and a lifting mechanism is vertically installed on the top of the U-shaped plate 9, and the lifting mechanism includes a first hydraulic cylinder 19, which is fixed on the top plate 6, and the bottom of the first hydraulic cylinder 19 is vertically fixed on the top of the U-shaped plate 9. The operation of the first hydraulic cylinder 19 provides power for the upper mold 3 to move toward the lower mold 2.

[0024] A first connecting rod 10 is installed on both sides of the U-shaped plate 9, the first connecting rod 10 is perpendicular to the second connecting rod 15, and both ends of the first connecting rod 10 are rotatably installed with inclined lifting rods 11, and rotating shafts 12 are rotatably installed on both sides of the bottom of the lifting rod 11, and a first fixed plate 13 is installed on the other end of the rotating shaft 12, the first fixed plate 13 is installed on the slider 14, and the slider 14 is slidably installed on the second connecting rod 15. When the upper mold 3 contacts the lower mold 2, the thrust of the first hydraulic cylinder 19 on the U-shaped plate 9 drives the slider 14 to slide on the second connecting rod 15, so that the U-shaped plate 9 approaches the first support plate 7, thereby converting the downward pressure of the first hydraulic cylinder 19 into the sliding power of the slider 14 and the rotational power of the lifting rod 11. At this time, as the slider 14 slides, it will contact and squeeze the second compression spring 27, so that the second compression spring 27 can buffer the downward pressure of the upper mold 3 while ensuring the downward pressure of the upper mold 3, thereby reducing the impact between the upper mold 3 and the lower mold 2.

[0025] When the machining equipment with a protective mechanism is in use, the workpiece is placed on the lower mold 2, and then the two molds approach each other and come into contact. At this time, due to the contact support of the lower mold 2 on the upper mold 3, the U-shaped plate 9 begins to move independently, so that the distance between the U-shaped plate 9 and the first support plate 7 gradually decreases. Then, when the distance between the U-shaped plate 9 and the first support plate 7 is reduced to a critical value, the push of the first hydraulic cylinder 19 will act on the first support plate 7 and be transmitted to the upper mold 3 to start the stamping process of the workpiece. After the processing is completed, the first hydraulic cylinder 19 will lift the U-shaped plate 9. At this time, the distance between the U-shaped plate 9 and the first support plate 7 will gradually increase and return to the initial position. Finally, the first support plate 7 will rise together with the U-shaped plate 9 to realize the mold opening operation.

[0026] Furthermore, in order to improve the stability of the lifting of the U-shaped plate 9, at least two guide rods 20 are provided in parallel on the side of the first hydraulic cylinder 19, the bottom of the guide rod 20 is fixed on the U-shaped plate 9, and the top of the guide rod 20 slides through the top plate 6, providing a guide for the lifting of the U-shaped plate 9.

[0027] Furthermore, if Figure 4 As shown, a second support plate 24 is correspondingly placed in the rectangular groove 4, the lower mold 2 is mounted on the top of the second support plate 24, and the support rod 5 slides through the corners of the second support plate 24, a cavity 25 is provided inside the base 1, the top of the cavity 25 is connected to the rectangular groove 4, and the rectangular groove 4 and the cavity 25 are stepped, so that the second support plate 24 can be placed in the rectangular groove 4, and a second hydraulic cylinder 26 is vertically installed at the bottom of the cavity 25, and the top of the second hydraulic cylinder 26 is fixedly connected to the second support plate 24. When the mold is closed, the lower mold 2 will rise under the push of the second hydraulic cylinder 26, so as to close with the upper mold 3, thereby increasing the pressure effect during the mold closing and improving the forming effect of the workpiece.

[0028] A controller 8 is installed on the side of the base 1, and the controller 8 is connected to the first hydraulic cylinder 19 and the second hydraulic cylinder 26 through wires. In actual use, the controller 8 is a PLC controller.

[0029] Furthermore, if Figure 1 As shown, the buffer comprises a disc 21, which is coaxially mounted on the support rod 5, and an annular plate 22 is coaxially arranged on both the upper and lower sides of the disc 21, the annular plate 22 is sleeved on the support rod 5, and a first compression spring 23 is arranged between the annular plate 22 and the disc 21, one end of the first compression spring 23 is fixed on the annular plate 22, and the other end of the first compression spring 23 is fixed on the disc 21. It not only limits the movement of the two molds, but also buffers the movement of the two molds. When the upper mold 3 is pressed down, the elastic action of the first compression spring 23 can reduce the self-gravity of the upper mold 3, and further reduce the impact between the upper mold 3 and the lower mold 2.

[0030] Furthermore, if Figure 3 As shown, a first limit block 17 is installed at the middle position of the top of the first support plate 7, and a second limit block 18 is correspondingly provided above the first limit block 17, and the second limit block 18 is fixedly connected to the U-shaped plate 9. The movement of the slider 14 on the second connecting rod 15 is limited, so that the lifting rod 11 always keeps its bottom tilted and spread outward, and prevents the two lifting rods 11 on the same second connecting rod 15 from approaching parallelism, so that the slider 14 lacks the horizontal force to slide on the second connecting rod 15, thereby affecting the downward pressure buffering of the upper mold 3 by the second compression spring 27.
