Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interior decoration, in particular to a safe and compact punching tool for automobile interior decoration parts. Background Art

[0002] In automotive interior products, such as bottom guard plates, left and right sides, etc., some holes with higher requirements need to be punched out separately after forming. Conventional punching tooling is that the lower mold does not move, and the upper mold is driven by a cylinder from top to bottom to achieve product punching.

[0003] Traditional tooling generally ensures that the lower mold frame is in a prohibited state, and the upper mold frame moves to achieve the action of cutting the product. The disadvantage is that the temporary space is relatively large, and the mold is working, which has a high safety risk. The cutting cylinder mechanism is difficult to maintain at the top. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a safe and compact punching tool for automobile interior decoration parts. The structural design space is relatively small, and the vulnerable structures are all in the lower die, which is easy to maintain. The upper die is ensured to remain stationary and the lower die is pulled by the cylinder to achieve high-position punching, and the safety factor is changed.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A safe and compact punching tool for automobile interior parts includes an upper die frame 1, a lower die frame 2, a cylinder 3, a guide structure 4, a welding frame 5, and a hydraulic station 6; wherein: the upper die frame 1 is supported by guide columns, the upper die frame 1 is pre-pressed by a floating die, and the floating die presses the product during the rise of the lower die frame 2; the lower die frame 2 is guided by the guide columns, and the cylinder controls the up and down movement of the lower die frame 2; the cylinder 3 drives the lower die frame 2 to open and close through the cylinder; the guide structure 4 realizes a four-column guide through the upper end of the guide column, the fixed lower end of the upper die frame 1 and the welding frame; the welding frame 5 is a base frame for heightening welding; the hydraulic station 6 is a drive system for providing cylinder movement.

[0007] Optimized: The upper mold frame 1 is the static mold, and the lower mold frame 2 is the dynamic mold.

[0008] Optimized: The guide structure 4 ensures that the upper mold frame 1 can achieve an up and down reciprocating motion through the guide pillars.

[0009] Optimized: The welded frame 5 ensures that the lower mold frame 2 is at a suitable height to facilitate workers to take and place parts.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The tooling of the utility model ensures that the upper die frame is stationary and the lower die frame moves from bottom to top, occupies a small space, works at a high point, and has a relatively high safety factor. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0022] A safe and compact punching tool for automobile interior parts includes an upper die frame 1, a lower die frame 2, a cylinder 3, a guide structure 4, a welding frame 5, and a hydraulic station 6; wherein: the upper die frame 1 is a static die, supported by guide columns, and pre-pressed by a floating die, and the floating die presses the product when the lower die frame 2 rises; the lower die frame 2 is a movable die, and the lower die frame 2 is slidably guided by guide columns, and the cylinder controls the up and down movement of the lower die frame 2; the cylinder 3 drives the lower die frame 2 to open and close through the cylinder; the guide structure 4 realizes a four-column guide through the upper mouth of the guide column, the fixed lower mouth of the upper die frame 1 and the welding frame, ensuring that the upper die frame 1 realizes an up and down reciprocating motion through the guide column; the welding frame 5 is a heightened and welded base frame, which ensures that the lower die frame 2 is at a suitable height for workers to conveniently pick up and place parts; the hydraulic station 6 is a drive system that provides cylinder movement.

[0023] A safe and compact punching tool for automotive interior parts operates as follows: Oil is pumped through the rear end of the cylinder to eject the workpiece. The lower die frame (1) is movable and opened. The semi-finished product is placed on the lower die frame. Oil is then pumped through the front end of the cylinder to pull the die back and cut the product (closed). A safety grating is installed on the operating side, making this bottom-up mechanism safer and more stable. The hydraulic station is located below the frame and is designed with wheels for easy removal for maintenance.

[0024] A safe and compact operating method for punching tooling for automobile interior parts: the tooling's reciprocating motion is achieved through starting, resetting, and emergency stopping on a mobile workbench.
