Description

Technical Field

[0001] This utility model relates to the field of valve cover processing technology, specifically a heated forging processing equipment for valve cover processing. Background Technology

[0002] Valves are control components in fluid transport systems. The valve cover generally refers to the valve cover, which is a detachable part of the main surface of the valve body assembly. It is usually connected to the valve body with high-strength bolts. When metal valve covers are initially formed, they are hot-forged at temperatures above the recrystallization temperature of the metal. Increasing the temperature can improve the plasticity of the metal valve cover.

[0003] When existing valve covers are hot-forged, the formed valve cover fits tightly to the mold cavity, and the wall thickness of the valve cover is relatively thin, making demolding difficult. When the valve cover is ejected by the lifting mechanism, it is mostly forcibly ejected by continuous ejection force. When the adhesion force between the valve cover and the mold cavity is large, it is very easy to cause local deformation of the valve cover at the ejection point. At the same time, it significantly increases the operating load of the lifting mechanism, which may lead to damage to its power components. Utility Model Content

[0004] The purpose of this utility model is to provide a heated forging processing equipment for valve cover processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heated forging and pressing equipment for processing valve covers includes a forging and pressing equipment body, a mold detachably connected inside the forging and pressing equipment body, and further includes:

[0007] A lifting assembly is installed inside the main body of the forging equipment. The lifting assembly includes a fixed frame that is fixedly installed on the upper surface inside the main body of the forging equipment. Slide rods are fixedly installed at the four corners of the lower surface of the fixed frame. Lifting plates are slidably connected to the outside of the slide rods. Multiple lifting rods are provided above the lifting plates. Sliding sleeves are fixedly connected to the lower ends of the multiple slide rods. A striking block is slidably inserted into the sliding sleeve.

[0008] The transmission assembly is located below the lifting assembly.

[0009] Furthermore, a limiting ring is fixedly installed on the outer surface of the striking block above the sliding sleeve.

[0010] Furthermore, the mold has multiple lifting holes on its lower surface and multiple through slots on its main body surface. The lifting rod movably passes through the through slots at corresponding positions and slides into the lifting holes.

[0011] Furthermore, the lower end of the lifting rod is composed of a screw, the middle of the lifting rod is composed of a square rod, and multiple threaded seats are fixedly installed on one side surface of the lifting plate. The screw of the lifting rod is screwed into the threaded seat at the corresponding position.

[0012] Furthermore, the transmission assembly includes:

[0013] The geared motor is fixedly installed on the lower surface inside the main body of the forging equipment.

[0014] An eccentric disc is fixedly installed at the output end of the geared motor.

[0015] Preferably, a connecting rod is rotatably connected to one side surface of the eccentric disk via a bearing, and a top block is rotatably connected to the other end of the connecting rod via a bearing. Two U-shaped connecting blocks are fixedly installed on the upper surface of the top block, and a storage groove is provided on the lower surface of the striking block to slide and insert with the U-shaped connecting blocks.

[0016] Preferably, a metal elastic lever is fixedly installed on the inner surface of the U-shaped connecting block, and arc-shaped locking blocks are fixedly installed on both sides of the U-shaped connecting block. Arc-shaped locking grooves are opened on both sides of the storage groove to engage with the arc-shaped locking blocks.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The up-and-down movement of the lifting rod is powered by the operation of the geared motor. When the valve cover is struck, if the valve cover and the mold cavity fit firmly, the valve cover will block the upward movement of the lifting rod. The arc-shaped locking block will move out of the lower arc-shaped locking groove and into the upper arc-shaped locking groove. When the top block moves down, the limiting ring restricts the downward movement of the striking block, causing the arc-shaped locking block to move out of the upper arc-shaped locking groove and into the lower arc-shaped locking groove so that the striking block can move up and strike again. This prevents the striking block from moving up continuously when the geared motor is running, thus avoiding the increase in the operating load of the geared motor due to the force of the lifting rod moving up continuously when the resistance is large.

[0019] 2. The striking block moves up and down repeatedly, causing the lifting plate to move up and down, which in turn moves multiple lifting rods out of the lifting hole and intermittently strikes the valve cover inside the mold cavity, thus moving the valve cover out. In this way, the valve cover is knocked out of the mold cavity by the force of the intermittent striking through the valve cover by the multiple lifting rods, instead of forcibly pushing the valve cover out by the continuous upward movement of the lifting rods. This reduces the local deformation of the valve cover caused by the continuous pushing force and also reduces the operating load of the transmission components. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-5 In this embodiment of the present invention, a heated forging processing equipment for valve cover processing includes a forging equipment body 1, a mold 101 detachably connected inside the forging equipment body 1, and a lifting assembly 2 disposed inside the forging equipment body 1. The lifting assembly 2 includes a fixed frame 201 fixedly installed on the upper surface inside the forging equipment body 1, and slide rods 202 fixedly installed at the four corners of the lower surface of the fixed frame 201. A lifting plate 204 is slidably connected to the outside of the slide rods 202. Multiple lifting rods 206 are disposed above the lifting plate 204. Sliding sleeves 203 are fixedly connected to the lower ends of the multiple slide rods 202. A striking block 207 is slidably inserted inside the sliding sleeve 203. A transmission assembly 3 is disposed below the lifting assembly 2.

[0028] Specifically, the transmission component 3 provides power for the operation of the lifting component 2, causing multiple lifting rods 206 to repeatedly strike the valve cover, moving the valve cover out of the mold cavity through the force of intermittent striking.

[0029] Example 1

[0030] like Figure 1-3As shown, in this embodiment, the lower surface of the fixed mold of the mold 101 is provided with multiple lifting holes 102, and the surface of the forging equipment body 1 is provided with multiple through slots 103. The lifting rod 206 movably passes through the through slots 103 at the corresponding positions and slides into the lifting holes 102. The lower end of the lifting rod 206 is composed of a screw, and the middle of the lifting rod 206 is composed of a square rod. Multiple threaded seats 205 are fixedly installed on one side surface of the lifting plate 204. The screw of the lifting rod 206 is screwed into the threaded seat 205 at the corresponding position. The screwed connection between the screw and the threaded seat 205 allows the lifting rod 206 to be disassembled. The shape of the square rod itself makes it easy to turn the lifting rod 206 with a tool.

[0031] In this embodiment, the striking block 207 moves up and down repeatedly, causing the lifting plate 204 to move up and down, so that multiple lifting rods 206 move out from inside the lifting hole 102 and intermittently strike the valve cover inside the mold cavity, thus moving the valve cover out. In this way, by opening the lifting hole 102 below the fixed mold, and by having multiple lifting rods 206 repeatedly move up and down inside the lifting hole 102 to strike the valve cover, the valve cover is knocked out of the mold cavity by the indirect striking force, instead of the lifting rods 206 continuously moving upward to forcibly push the valve cover out, reducing the local deformation of the valve cover caused by the continuous pushing force, and also reducing the operating load of the transmission component 3.

[0032] like Figure 2-5 As shown, in this embodiment, the transmission component 3 includes: a reduction motor 301 fixedly installed on the lower surface inside the forging equipment body 1, and an eccentric disk 302 fixedly installed on the output end of the reduction motor 301; a connecting rod 303 is rotatably connected to one side surface of the eccentric disk 302 via a bearing, and a top block 304 is rotatably connected to the other end of the connecting rod 303 via a bearing; two U-shaped connecting blocks 305 are fixedly installed on the upper surface of the top block 304; a storage groove 308 is provided on the lower surface of the striking block 207 to slide and insert into the U-shaped connecting block 305; a metal elastic paddle 306 is fixedly installed on the inner surface of the U-shaped connecting block 305; arc-shaped locking blocks 307 are fixedly installed on both sides of the U-shaped connecting block 305; and arc-shaped locking grooves 309 are provided on both sides of the storage groove 308 to movably engage with the arc-shaped locking blocks 307.

[0033] In practice, the geared motor 301 operates, driving the eccentric disc 302 to rotate. Through the transmission of the connecting rod 303, under the sliding limit of the striking block 207 and the sliding sleeve 203, the force of the geared motor 301 rotating is converted into the force of the striking block 207 reciprocating up and down, providing power for the up and down movement of the lifting rod 206. When striking the valve cover, if the valve cover and the mold cavity are firmly attached, the valve cover will block the upward movement of the lifting rod 206. At this time, the resistance is greater than the force that moves the arc-shaped locking block 307 out of the arc-shaped locking groove 309, causing the arc-shaped locking block 307 to move out of the lower arc-shaped locking groove 309 and into the upper arc-shaped locking groove 309. When the geared motor 301 continues to rotate, the striking block 207 is not allowed to continue to move upward, so as to avoid the force of the lifting rod 206 continuously moving upward when the resistance is large, which would increase the operating load of the geared motor 301.

[0034] like Figure 3 As shown, in this embodiment, a limiting ring 208 is fixedly installed on the outer surface of the striking block 207 above the sliding sleeve 203.

[0035] In practice, when the top block 304 moves down, the limiting ring 208 restricts the downward movement of the striking block 207, so that the arc-shaped locking block 307 moves out of the upper arc-shaped locking groove 309 and into the lower arc-shaped locking groove 309, so that the striking block 207 can move up and strike again.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
