DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] like Figure 1-5 As shown, an energy absorption box punching device includes a frame 1, on which a punching mechanism for punching an energy absorption box workpiece is arranged, and the punching mechanism includes a fixed seat sleeve 21 for fixing the energy absorption box workpiece, and a punching die 22 is arranged in the fixed seat sleeve 21, and a receiving space for placing the energy absorption box workpiece is formed between the fixed seat sleeve 21 and the punching die 22. Punching holes 23 are opened on the fixed seat sleeve 21 and the punching die 22 corresponding to the hole positions to be processed of the energy absorption box, and a punch 24 is movably connected in the punching hole 23, and the punch 24 is provided with reciprocating power through a hydraulic system 25.

[0026] When in use, the energy absorbing box workpiece is placed in the accommodation space of the punching fixed seat cover 21 and the punching die 22 to complete positioning and fixing, and the hydraulic system 25 is started to drive the punch 24 to move forward through the punching hole 23 of the fixed seat cover 21 to perform a punching operation on the energy absorbing box workpiece. The accommodation space formed by the fixed seat cover 21 and the punching die 22 limits the displacement of the energy absorbing box workpiece. When the punch 24 contacts the energy absorbing box workpiece and continues to move forward, a shear force is formed under the support of the die to remove the material at the hole to be processed, and the punching operation of the energy absorbing box workpiece is completed.

[0027] This embodiment adopts a stamping operation method, fixes the energy absorption box workpiece by fixing the seat cover 21 and the stamping die 22, and completes the punching operation by the punch 24, eliminating the trouble of repeatedly taking and placing the workpiece in the traditional machining operation method, and greatly improves the problems of cumbersome operation, low processing efficiency and poor precision.

[0028] In a further embodiment, a guide structure is provided corresponding to the punch 24 to improve the precision of the movement of the punch 24 and ensure the processing quality of the energy absorption box.

[0029] As a first embodiment of the guide structure, Figure 4As shown, the guide structure includes a slider 31 fixedly connected to the punch 24, the slider 31 is slidably connected to the linear slide 32, and the slide is fixedly connected to the frame 1. The sliding cooperation between the slider 31 and the slide provides a guiding effect for the action of the punch 24 to ensure the punching accuracy. Preferably, the slider 31 and the linear slide adopt a dovetail fit. Although this embodiment can improve the action accuracy of the punch 24, the configuration of the slider 31 and the linear slide 32 guide structure occupies a large space, especially for holes with a small hole spacing. It is usually impossible to arrange the guide structure for each hole position respectively, and it can only be processed in separate processes, which restricts the efficiency improvement.

[0030] As a second embodiment, Figure 5 As shown, in order to improve the above defects, the guide structure is a guide sleeve 33 provided corresponding to the punch 24, and the guide sleeve 33 is fixedly connected to the fixed seat sleeve 21 corresponding to the punching hole 23, and the punch 24 and the inner diameter of the guide sleeve 33 are axially slidably matched. Preferably, the guide sleeve 33 includes a positioning end 34 for connecting to the fixed seat sleeve 21 and an extension end 35 coaxially arranged with the positioning portion, and a fixed ear plate 36 is provided on the guide sleeve 33. When in use, the guide sleeve 33 is sleeved in the punching hole 23 through the positioning portion, and is fixedly connected to the fixed seat sleeve 21 through the fixed ear plate 36, and the extension portion is reserved outside the fixed seat sleeve 21. Compared with the above embodiment, this embodiment simplifies the guide structure and reduces the volume of the guide structure, so that it can be applied to the punching operation of the energy absorption box workpiece with a relatively close hole position, eliminating the trouble of punching the energy absorption box workpiece in a unified process, and ensuring the operation efficiency.

[0031] Preferably, the guide sleeve 33 is made of Cr12MoV material and is quenched to ensure the strength and wear resistance of the guide sleeve 33. The fixed seat sleeve 21 is preferably made of Q235 material.

[0032] Furthermore, the stamping mechanism also includes an ejection structure, which is used to perform an ejection action on the stamped energy absorption box to realize the automatic ejection of the energy absorption box workpiece. The ejection structure includes an ejector rod 26 set corresponding to the energy absorption box, and the ejection end of the ejector rod 26 is telescopically connected to the bottom of the accommodation space formed by the fixed seat cover 21 and the stamping die 22. The tail end of the ejector rod 26 is connected to the cylinder 27 to obtain the power of the ejection action of the ejector rod 26. The ejection operation of the energy absorption box workpiece is completed by driving the ejection action of the ejector rod 26 by the cylinder 27, which reduces the labor intensity and improves the work efficiency.

[0033] Furthermore, the stamping mechanism also includes a chip removal structure 28 for discharging stamping waste. The chip removal structure 28 is a discharge pipe connecting the fixed seat sleeve 21 and the bottom of the stamping die 22, which facilitates the timely discharge of waste.

[0034] The above disclosure is only a specific embodiment of the present patent, but the present patent is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, the deformation made should be deemed to belong to the protection of the present invention.
