Description

Technical Field

[0001] The utility model relates to a spring hook bending device, belonging to the technical field of spring processing equipment. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. They are generally made of spring steel. There are many types of springs, and according to their shapes, they mainly include spiral springs, scroll springs, leaf springs, special-shaped springs, etc. After the production of traditional springs, hooks will be formed at both ends of the spring, and the hook is at 90° to the spring. The hook needs to be bent so that the hook and the spring are set horizontally, which is convenient for hanging the spring later.

[0003] Publication No.: CN220295731U, mentions a spring hook bending device, which places the spring body inside the positioning groove, and drives the bending block to rotate through the output of the driving motor, so that when the bending block rotates, the hook assembly can be bent, so that the hook assembly and the spring body are bent from a vertical state to a horizontal state, which is convenient for hanging the spring body. However, the device can only bend the hook at one end of the spring each time it is used. When the hook at the other end of the spring needs to be bent, the spring needs to be removed and replaced, which is not convenient enough. Now there is an urgent need for a spring hook bending device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a spring hook bending device, including a base 1, a movable spring limiting seat 5 and a fixed spring limiting seat 8, a fixed side plate 2 is longitudinally fixed on the left side of the upper end of the base 1, a push-pull rod 3 is movably passed through the middle of the fixed side plate 2, and a reset spring 4 is installed on the front and rear sides of the right end of the fixed side plate 2, the movable spring limiting seat 5 is slidably located on the upper side of the base 1, and a fixed plate 6 is installed on the front and rear ends of the fixed side plate 2. Electric push rods 7 are installed on the right ends of the two fixed plates 6, and the fixed spring limiting seat 8 is fixed on the right side of the upper end of the base 1. On the side, a spring 16 to be processed is clamped between the fixed spring limit seat 8 and the movable spring limit seat 5, a hidden groove 9 is opened at the right end of the fixed spring limit seat 8, a fixing plate 10 is fixed in the middle of the hidden groove 9, small push rods 11 are installed at the front and rear ends of the fixing plate 10, and metal push blocks 12 are installed at the movable ends of the two small push rods 11. This design solves the problem that the original device can only bend the hook at one end of the spring each time it is used, and when the hook at the other end of the spring needs to be bent, the spring needs to be removed and replaced, which is not convenient enough.

[0019] As the first embodiment of the utility model: the left and right ends of the base 1 are both installed with threaded mounting blocks 15, and the added threaded mounting blocks 15 can be fixed to the external workbench by external bolts, so as to facilitate the stable installation of the base 1. The two reset springs 4 and the push-pull rod 3 are fixed to the left end surface of the movable spring limit seat 5, and the added push-pull rod 3 can pull the movable spring limit seat to move left and right, and the two reset springs 4 can push the movable spring limit seat 5 to move right, so that when the spring 16 to be processed is limited between the fixed spring limit seat 8 and the movable spring limit seat 5, the movable spring limit seat 5 will not move left by itself.

[0020] The two metal push blocks 12 are respectively movably attached to the front and rear end hooks of the spring 16 to be processed. When the two added metal push blocks 12 are pushed forward, the front and rear end hooks of the spring 16 to be processed can be pushed to bend and deform. The upper and lower sides of the right end of the hidden groove 9 are provided with a slide rail groove 13. The added slide rail groove 13 facilitates the installation of the slide rail piece 14. The slide rail piece 14 is slidably arranged between the two slide rail grooves 13. The added slide rail piece 14 can hide the two small push rods 11 and the sides of the two metal push blocks 12.

[0021] As a second embodiment of the utility model: when the spring hook needs to be bent, the push-pull rod 3 is pulled to the left, the movable spring limiting seat 5 moves to the left and separates from the fixed spring limiting seat 8, and the two return springs 4 are squeezed and compressed, and then the spring 16 to be processed is placed on the left end of the fixed spring limiting seat 8, so that the two metal push blocks 12 are respectively attached to the front and rear end hooks of the spring 16 to be processed, and then the push-pull rod 3 is released, and the two return springs 4 are reset to push the movable spring limiting seat 5 to the right, so that the movable spring limiting seat 5 and the fixed spring limiting seat 8 cooperate to limit the spring 16 to be processed (reference Figure 1 ), then simultaneously start the small push rods 11, the movable ends of the two small push rods 11 can push the two metal push blocks 12 to move in opposite directions, because the two metal push blocks 12 are respectively attached to the front and rear end hooks of the spring 16 to be processed, the two metal push blocks 12 can push and bend the front and rear end hooks of the spring 16 to be processed, and simultaneously start the two electric push rods 7, the movable ends of the two electric push rods 7 slowly move to the right, which can prevent the spring 16 to be processed from being stretched, and at the same time, the right sides of the movable ends of the two electric push rods 7 can also squeeze the bent front and rear end bending hooks of the spring 16 to be processed, so that the front and rear end hooks of the spring 16 to be processed can be bent between 75° and 90°, which is quick and convenient.
