Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment for hardware manufacturing, and particularly relates to cutting equipment for hardware manufacturing. Background Art

[0002] The cutting equipment used in hardware manufacturing consists of a cutting knife assembly and a base. The hardware is placed on the base and the cutting blade is used to cut the hardware.

[0003] The existing cutting equipment for hardware manufacturing is mainly used for cutting and processing hardware parts during hardware manufacturing. The equipment has the following defects during cutting operations: (1) The existing cutting equipment for hardware manufacturing drives the screw to rotate through a handwheel, so that the screw pushes the pressure block to press the hardware to avoid shaking during cutting. However, during actual cutting processing, it is easy to accidentally touch the handwheel and drive the screw to rotate, changing the pressing degree of the pressure block, causing the hardware to become loose. For this reason, we propose a cutting equipment for hardware manufacturing. Utility Model Content

[0004] The purpose of the present utility model is to provide a cutting device for hardware manufacturing, so as to solve the problem in the background art that the state of the hardware manufacturing cutting device easily changes during the cutting process due to the pressing block pressing the hardware, resulting in the loosening of the hardware.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting device for hardware manufacturing, comprising a base, a cutting knife assembly being provided on the base, a threaded seat being fixed on the surface of the base, a screw being connected to the threaded seat via a thread, one end of the screw being connected to a movable pressure block, the other end of the screw being connected to an end tube, a movable column being connected to the interior of the end tube via a sliding connection, a handwheel being fixed to one end of the movable column, a slot being provided on the end face of the movable column, an insertion rod being fixed to the interior of the end tube, one end of the insertion rod being inserted into the corresponding slot, a top spring being provided at the other end of the movable column, and the top spring being located inside the end tube.

[0006] Preferably, an anti-slip block is fixed to the outer wall of the movable column, an anti-slip groove with a circular cross-section is opened on the inner wall of the end tube, and one end of the anti-slip block is placed inside the anti-slip groove.

[0007] Preferably, a spherical groove is provided on the surface of the anti-slip block, and a ball is embedded in the spherical groove.

[0008] Preferably, a supporting column is provided on the inner side of the top spring, a supporting tube is sleeved on the outer wall of the supporting column, the supporting tube is fixed inside the end tube, and the supporting column is fixed on the end surface of the movable column.

[0009] Preferably, the longitudinal sections of the movable column and the end tube are both circular structures, and the cross section of the movable column is a convex structure.

[0010] Preferably, the longitudinal sections of the supporting cylinder and the supporting column are circular structures, and the central axes of the supporting cylinder, the movable column, the end cylinder and the supporting column coincide with each other.

[0011] Preferably, the surface of the end barrel and the surface of the screw are connected together with a rib plate, and the cross-section of the rib plate is a triangular structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) Through the designed end tube, top spring, insertion rod, slot and movable column, the end tube is sleeved on the outside of the movable column, and the two are connected between the hand wheel and the screw, so that the hand wheel can rotate freely at the end of the screw. Then, during cutting, accidentally touching the hand wheel will not cause the screw to rotate and change the clamping degree of the hardware, making the processing of the utility model more reliable. When it is necessary to adjust the position of the movable pressure block, press the hand wheel to insert one end of the insertion rod into the slot. At this time, turning the hand wheel can drive the screw to rotate, adjust the position of the movable pressure block, and wait for it to be adjusted. When the handwheel is released, the top spring in the compressed state releases the elastic force, pushing the movable column to move, so that one end of the rod is promptly disengaged from the slot. The movable column is limited by the designed anti-slip groove and anti-slip block to prevent it from escaping from the end tube. The designed ball bearings increase the sliding lubricity between the surface of the anti-slip block and the anti-slip groove to reduce wear. The designed support columns and support tubes limit the extrusion deformation of the top spring to avoid excessive bending and loss of elasticity. The designed ribs reinforce the connection between the end tube and the screw to avoid cracking. BRIEF DESCRIPTION OF THE DRAWINGS
