Description

Technical Field

[0001] The utility model relates to the technical field of forging equipment, in particular to a hot end die pressing slide block and a hot die forging press machine. Background Art

[0002] Hot die forging presses are used for die forging of metals in manufacturing industries such as automobiles, tractors, internal combustion engines, ships, aviation, mining machinery, petroleum machinery, and hardware tools. The forged forgings have high precision and high productivity, are easy to realize automated production, and have low requirements on workers' operating skills. They are increasingly widely used in modern forging production and are indispensable high-precision forging equipment in modern forging production.

[0003] Hot forging presses are mainly classified into two categories according to the actuator: crank slider mechanism and crank connecting rod-wedge mechanism. Although the latter is beneficial to the press stiffness and anti-eccentric load capability, compared with the former, the structure is more complicated, the equipment weight is increased, and maintenance is relatively difficult. Therefore, more die section manufacturers use crank slider mechanism type of press. This type of hot forging press can be found in the Chinese patent document with publication number CN115255240A (patent name: A precision hot forging press), which includes a body, a slideway is provided inside the body, a slider is slidably connected in the slideway, slide grooves are symmetrically provided on both side walls of the slideway, slide plates matching the slide grooves are fixedly connected on both sides of the slider, a motor is fixedly installed in the cavity of the body, a flywheel is fixedly installed on the output shaft of the motor, a connecting rod is rotatably connected to one side of the flywheel, a long rod is rotatably connected to one end of the connecting rod, the long rod is fixedly connected to the upper surface of the slider, an upper die is fixedly connected to the lower surface of the slider, a lower die is fixedly connected to the inner bottom of the slideway, and a die cavity is provided on the upper surface of the lower die. When in use, the motor drives the flywheel to rotate, thereby driving the connecting rod to move up and down, and then driving the slider to move up and down through the long rod, and the slider drives the upper die to move up and down, and the metal blank is placed in the die cavity of the lower die through the up and down reciprocating movement of the slider, and the upper die forges the metal blank.

[0004] It can be seen that the role of the slider in the hot die forging press cannot be underestimated. Its processing accuracy is directly related to the normal operation of the hot die forging press. As the slider is used for a long time, the slider will deform due to reasons such as partial load, resulting in unsmooth sliding between the slider and the slide. The general treatment method is to grind and repair the surface of the slider, but this method can only meet the needs of the first few deformation grinding uses. As the number of grinding increases, the slider is excessively "thinned", which seriously reduces the matching accuracy between it and the slide. The slider is prone to movement and the slider moves unstably, thus affecting the forging quality. If the above problems are solved by replacing the slider, due to the high price of the slider, this method will greatly increase the production cost, which is not conducive to the growth of the company's economic benefits.

DETAILED DESCRIPTION

[0024] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0025] See also Figure 1-Figure 5 The utility model provides a hot die forging slider for cooperating with the slide groove 401. The hot die forging slider comprises a slider body 11 and a slide plate 12. The side wall of the slider body 11 is symmetrically provided with mounting grooves 111. The slide plate 12 has two, one slide plate 12 corresponds to one mounting groove 111, and the slide plate 12 is mounted in the corresponding mounting groove 111. The slide plate 12 partially protrudes to the outside of the mounting groove 111 and is slidably connected to the slide groove 401. A slot 112 that simultaneously passes through the two mounting grooves 111 is provided in the slider body 11. A shaft sleeve 13 is fixedly installed in the slot 112. The end surfaces of the two slide plates 12 that are away from each other are both recessed inward to form a groove 121. A bolt 14 is installed on the slide plate 12. The tail of the bolt 14 passes through the shaft sleeve 13 through the groove 121 on one side and then extends into the other groove 121. A nut 15 is installed at the tail of the bolt 14, and a plug 16 is installed at the open end of the groove 121.

[0026] When assembling the hot die forging slider of the present invention, firstly, the two sliders 12 are symmetrically arranged in the mounting grooves 111 on the opposite sides of the slider body 11, and then the tail of the bolt 14 passes through the groove 121 on one side through the shaft sleeve 13 and extends into the groove 121 on the other side, and is locked by the nut 15. At this time, the two sliders 12 are fixed on the opposite side walls of the slider body 11.

[0027] When in use, the portion of the slide plate 12 protruding from the outside of the mounting groove 111 of the slider body 11 is used to slide and match with the slide groove 401, and the slider body 11 does not contact the slide groove 401. After long-term use, the slider will be deformed due to the influence of the eccentric load, resulting in poor sliding between the slide plate 12 and the slide groove 401. Under the premise that it can be repaired by grinding, the nut 15 and the bolt 14 can be removed in sequence, and then the slide plate 12 can be removed from the slider body 11, so as to grind and repair the surface of the slide plate 12 that matches the slide groove 401. After completion, the slide plate 12 can be installed on the slider body 11 for use. When the repair of the slide plate 12 by means of grinding cannot meet the use requirements, at this time, a new slide plate 12 can be replaced and installed on the original slider body 11, avoiding the waste of the slider body 11, saving production costs, and ensuring the stability of the slider, making it more reliable. In addition, the setting of the shaft sleeve 13 enhances the structural strength of the position of the slot 112 on the slider body 11, effectively reducing deformation. Furthermore, the plug 16 fills part of the space of the groove 121 , thereby enhancing the structural strength at the position of the groove 121 and preventing the slide plate 12 from being easily deformed.

[0028] The sleeve 13 is a tubular structure with two ends through, and the sleeve 13 and the slot 112 are interference fit, and the sleeve 13 and the tail of the bolt 14 are clearance fit. The sleeve 13 is a metal sleeve, for example, it can be made of metal materials such as brass or cast iron, which has good wear resistance and high strength, and can prevent the sleeve 13 from being easily worn and deformed.

[0029] As a preferred embodiment, the mounting groove 111 is a waist-shaped structure extending in the longitudinal direction. The skateboard 12 cooperates with the mounting groove 111. When the skateboard 12 is installed in the mounting groove 111, the outer wall of the skateboard 12 fits with the groove wall of the mounting groove 111. On the one hand, it is convenient for quick positioning when installing the skateboard 12. On the other hand, the mounting groove 111 can have a certain limiting effect on the skateboard 12, which effectively prevents the skateboard 12 from moving relative to the slider body 11 in the longitudinal direction, reduces the load on the bolt 14 in the radial direction, and ensures the working stability of the bolt 14.

[0030] In this embodiment, each slide plate 12 has two grooves 121, which are symmetrically arranged at the upper and lower ends of the slide plate 12. Correspondingly, there are also two bolts 14, which together fix the slide plate 12 to the slider body 11, with high connection strength and more reliable use. In order to further improve the connection strength, an open washer 141 is sleeved on the outside of the bolt 14, and the open washer 141 is squeezed and fixed between the head of the bolt 14 and the bottom wall of the groove 121.

[0031] As a preferred embodiment, the groove 121 is a circular groove, and an internal thread is provided on the inner wall of the circular groove. The plug 16 is a stud structure, and the plug 16 is threadedly connected to the internal thread. When installing the plug 16, the plug 16 can be installed on the open end of the groove 121 by simply rotating the plug 16, which is simple and convenient to install. In order to facilitate the rotation of the plug 16, an operating portion 161 is provided on the outer end surface of the plug 16, and the operating portion 161 can be a straight or cross-shaped groove to facilitate the installer to rotate the plug 16 through a corresponding screwdriver.

[0032] As a preferred embodiment, an edge 122 is protruded outwardly on the outer wall of the slide plate 12 protruding to the outside of the mounting groove 111. The surface of the edge 122 away from the slider body 11 is coplanar with the surface of the slide plate 12 away from the slider body 11, and is slidably connected with the slide groove 401. By fixing the edge 122 at the end of the slide plate 12, the structural strength of the slide plate 12 is enhanced, and the slide plate 12 is prevented from being easily deformed. At the same time, the edge 122 fits with the slide groove 401, increasing the contact area, and ensuring that the slide plate 12 moves stably relative to the slide groove 401.

[0033] The utility model also provides a hot die forging press, including the hot die forging slider mentioned above, and also including a machine body 4, a flywheel 5, a connecting rod 6 and a motor 7 for driving the flywheel 5 to rotate, a slide 401 is longitudinally opened on the machine body 4, the hot die forging slider is slidably arranged in the slide 401 through a slide plate 12, a fixed frame 41 is fixedly installed on the machine body 4, the flywheel 5 is rotatably installed on the fixed frame 41, one end of the connecting rod 6 is hinged to the slider body 11, and the other end of the connecting rod 6 is hinged to the edge of the flywheel 5. In this way, when the motor 7 is started, the flywheel 5 is driven to rotate, and under the connection of the connecting rod 6, the hot die forging slider slides along the slide 401 to realize the forging action. Among them, the motor 7 can be installed on the fixed frame 41 to directly drive the flywheel 5 to rotate, or it can drive the flywheel 5 to rotate through a transmission method such as a belt drive or a chain drive. In this embodiment, the machine body 4 includes two oppositely arranged vertical plates, and the two slides 401 are respectively opened on the opposite surfaces of the two vertical plates.

[0034] In addition, the hot die forging press of the utility model also includes an upper die 8 and a lower die 9. The upper die 8 is fixedly mounted on the bottom of the slider body 11, and the lower die 9 is fixedly mounted on the machine body 4 and is located directly below the upper die 8. When in use, the lower die 9 is used to place the forged blank, and the lower die 8 is used to forge the blank.

[0035] The hot die forging slider or hot die forging press of the utility model divides the slider into two parts: a slider body 11 and a slide plate 12. The slide plate 12 is detachably mounted on two opposite sides of the slider body 11 for cooperating with the slide groove 401. When the slider is deformed by an offset load, resulting in poor sliding between the slide plate 12 and the slide groove 401 and inability to be repaired by grinding, the new slide plate 12 structure can be replaced while the slider body 11 is still in use, thereby ensuring stable sliding of the slider and avoiding waste, greatly reducing production costs, and being beneficial to the growth of corporate benefits.
