Description

TECHNICAL FIELD

[0001] The utility model relates to a punch press's sliding block plate, especially a replaceable punch press's sliding block plate structure. BACKGROUND

[0002] In the punch press process, "entering the baby" refers to that the sliding block plate enters the baby through the upper sliding block and locks the punch with screws, so as to facilitate the stamping operation. Specifically, it describes that the sliding block plate enters the baby through the sliding block and combines the punch, and when the punch runs to the lower dead point, the stamping operation is carried out on the workpiece to complete the stamping, shearing, calendering and other processing steps.

[0003] Referring to Figure 1 As shown in the figure, generally speaking, the sliding block plate 11 of the punch press 10 is arranged at the lower end of the sliding block 12 and is driven by the sliding block 12 to move linearly; in addition, the lower end of the sliding block plate 11 is provided with a central locking hole (not shown in the figure), so that after the punch 13 is installed at the lower end of the sliding block plate 11, the punch 13 is locked in the central locking hole of the sliding block plate 11 through locking members, which is the aforementioned entering baby structure, so as to facilitate the punch 13 to perform the stamping operation in the high-frequency and high-pressure working environment.

[0004] However, when the punch press 10 operates in the high-frequency and high-pressure working environment for a long time, the central locking hole of the sliding block plate 11 may be deformed or damaged due to excessive wear, material fatigue or loosening of the locking members. Such damage will directly affect the installation stability of the punch 13, causing the punch 13 to deviate or shake during movement, and ultimately affecting the running stability and processing precision. At this time, the entire sliding block plate 11 needs to be replaced, thereby increasing the cost. UTILITY MODEL CONTENTS

[0061] Referring to Figures 2 to 5 the drawings, the present utility model embodiment provides a replaceable punch press slider plate structure, which is suitable for being locked at the lower end surface 21 of a slider 20. The replaceable punch press slider plate structure mainly comprises a plate body 30, a replacement module A, and two locking screws 70. Wherein:

[0062] The plate body 30 is locked at the lower end surface 21 of the slider 20, and has an upper plate surface 31, a lower plate surface 32 opposite to the upper plate surface 31, a front plate surface 33, a rear plate surface 34 opposite to the front plate surface 33, an assembly recess 35 penetrating through the upper plate surface 31, the lower plate surface 32 and a portion of the front plate surface 33, and two assembly rail grooves 36 oppositely arranged at both sides of the assembly recess 35 and recessed from the upper plate surface 31 to the lower plate surface 32. The assembly recess 35 has two side planes 351 oppositely arranged, a supporting surface 352 arranged between the two side planes 351, and two avoiding recesses 353 arranged between the side planes 351 and the supporting surface 352, respectively. The two assembly rail grooves 36 extend along a transverse direction X.

[0063] The replacement module A is detachably arranged in the assembly recess 35 of the plate body 30, and has two assembly rail bars A1 arranged in the assembly rail grooves 36, and a central locking hole A2 arranged along a longitudinal direction Y. In this embodiment, the replacement module A includes a first module 40, a second module 50, and two bolts 60.

[0064] The first module 40 is detachably arranged in the plate body 30 along the transverse direction X, and has a first side surface 41 abutting against the side plane 351, a first end surface 42 abutting against the supporting surface 352, an end corner portion 43 arranged between the first side surface 41 and the first end surface 42 and located in the avoiding recess 353, a first block body 44 located in the assembly recess 35, a first rail segment 45 arranged at both sides of the first block body 44 and arranged in the assembly rail groove 36, a first recess hole portion 46 arranged in the first block body 44, and two longitudinal through holes 47 penetrating through the first block body 44 along the longitudinal direction Y.

[0065] The second module 50 is detachably arranged in the first module 40 along the transverse direction X, and has a second block body 51 located in the assembly recess 35, a second rail segment 52 arranged at both sides of the second block body 51 and arranged in the assembly rail groove 36, a second recess hole portion 53 arranged in the second block body 51 and constituting the central locking hole A2 with the first recess hole portion 46, and two transverse through holes 54 penetrating through the second block body 51 along the transverse direction X. The second rail segment 52 and the first rail segment 45 constitute the assembly rail bar A1.

[0066] The two bolts 60 each have a first head portion 61 abutting against the second block body 51, a first body portion 62 connecting the first head portion 61 and penetrating through the transverse through hole 54 of the second block body 51 along the transverse direction X, and a first locking portion 63 connecting the first body portion 62 and locked with the first block body 44 along the transverse direction X, so as to lock the second module 50 with the first module 40.

[0067] The two locking screws 70 each have a second head 71 abutting below the first block body 44, a second body 72 connecting the second head 71 and penetrating the longitudinal hole 47 of the first block body 44 along the longitudinal direction Y, and a second locking portion 73 connecting the second body 72 and locked to the slide block 20.

[0069] When the punch slide block plate is deformed or damaged in the central locking hole A2 under the high-frequency and high-pressure operation environment, only need to remove the two locking screws 70 from the plate body 30 along the longitudinal direction Y, the replacement module A can be removed from the plate body 30 along the transverse direction X, and the new punch slide block plate A can be replaced, even the damage of the central locking hole A2 can be judged from the first concave hole portion 46 of the first module 40 or the second concave hole portion 53 of the second module 50, and the damaged first module 40 or the second module 50 can be replaced.

[0070] Accordingly, through the assembly recess 35 and the assembly rail groove 36 structure of the plate body 30, combined with the assembly rail A1 design of the replacement module A, the replacement module A can be detachably arranged on the plate body 30, so that when the punch slide block plate is deformed or damaged in the central locking hole A2 under the high-frequency and high-pressure operation environment, only need to replace the replacement module A, without replacing the entire punch slide block plate, thereby reducing the manufacturing cost, and also ensuring the stability and accuracy of the punch driven by the replacement module A under the high-frequency and high-pressure working environment.

[0071] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
