[0002] Spring hooks are a common hardware product, widely used in mountaineering buckles, rope buckles, pet chains, key accessories, special-shaped chains, luggage buckles, connecting hooks, anti-skid chains and other products. Spring hooks are mostly gourd-shaped, with a C-shaped long section and a straight short section hinged into a closed ring through rivets, and a spring is installed between the long section and the short section to keep the long section and the short section in a normally closed state. At present, the traditional process for processing the long section of the spring hook is: first, the profile is processed into a spring hook blank with a small arc part; then the spring hook blank is processed by multiple different processing devices to make it a formed C-type spring hook. The processing device includes a mechanism for milling chamfers on the head of the spring hook blank, a mechanism for milling teeth on the head of the spring hook blank, a mechanism for milling two planes on the head of the spring hook blank, a mechanism for milling straight grooves on the tail of the spring hook blank, a mechanism for milling oblique grooves and cutting heads on the tail of the spring hook blank, a mechanism for deburring, and a mechanism for bending the spring hook blank. Each processing step is completed by manual operation, and after completing a step, the spring hook blank is also manually transported to the next station. This processing technology requires multiple processing personnel to operate, and its mechanical automation level is low, the production efficiency is low, and the manufacturing cost of the spring hook is correspondingly high.

DETAILED DESCRIPTION

[0020] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0021] Depend on Figure 1 Combination Figure 2-4As shown, a spring hook long section clamping device includes a clamp frame 21, a clamp core rod 22 and a clamp limit assembly 23. The clamp frame 21 is provided with a clamping notch 211. The clamp core rod 22 has a first position for inserting into the clamping notch 211 for horizontally limiting the long section to be processed and a second position for retracting to facilitate the placement of the long section to be processed. The clamp limit assembly 23 is arranged above the clamping notch 211 and is used for vertically limiting the long section to be processed. The beneficial effect of the present invention is that the clamping notch is provided for placing the spring hook long section, and the horizontal limit is achieved by the clamp core rod, and the vertical limit is achieved by the clamp limit assembly, so that the product is convenient and reliable to fix, and the structure is simple.

[0022] The clamp limit assembly 23 includes a first clamp slider 231 and a second clamp slider 232. The first clamp slider 231 is connected to the second clamp slider 232 and is used to drive the second clamp slider 232 to reciprocate. The second clamp slider 232 has a first position and a retracted second position for vertically limiting the long section to be processed, with the cover placed above the clamping notch 211. Specifically, the first clamp slider 231 is vertically arranged, and the second clamp slider 232 is horizontally arranged. The first clamp slider 231 drives the second clamp slider 232 to move horizontally by moving up and down. The long section to be processed can be limited by driving the first clamp slider to move vertically and then driving the second clamp slider to move horizontally. Of course, in the actual production process, a driving member can be set at at least one end of the first clamp slider, and of course, it can also be not set. More specifically, in order to facilitate operation, the first clamp slider extends out of the clamp frame. In the present invention, one end of the first clamp slider extends out of the clamp bottom plate, and the other end extends out of the clamp top plate. Of course, in practice, only one end may extend out of the clamp body, and even the driving member may be extended into the clamp frame to operate the first clamp slider to move up and down. Such a structure enables the first clamp slider to reliably drive the second clamp slider to move.

[0023] The first clamp slider 231 is provided with a clamp driving hole 2311, and the second clamp slider 232 is provided with a clamp driving shaft, which is arranged through the clamp driving hole 2311, and the inner wall of the clamp driving hole 2311 is provided with a clamp driving inclined wall 2312 for driving the clamp driving shaft to move horizontally. Such a structure enables the first clamp slider to reliably drive the second clamp slider to move, and even if the second clamp slider is subjected to horizontal force, it is difficult to drive the first clamp slider to move vertically, so that the product movement is reliable.

[0024] The clamp frame 21 includes a clamp anti-sliding block 212 for horizontally limiting the first clamp slider 231, and the second clamp slider 232 is provided with a clamp giving way groove 2321. The first clamp slider 231 is arranged between the clamp anti-sliding block 212 and the second clamp slider 232. Such a structure prevents the first clamp slider from sliding horizontally during product processing, making the second clamp slider unreliable in pressing the material, and causing the product to fall off.

[0025] The clamp frame 21 is provided with a clamp pressing assembly 24, and the clamp pressing assembly 24 includes a clamp fixing block 241 and a clamp pressing block 242. The clamp fixing block 241 is connected to the clamp frame 21, and the clamp fixing block 241 is connected to the clamp pressing block 242 through a clamp pressing rod. When the second clamp slider 232 is in the first position, the clamp pressing block 242 abuts against the second clamp slider 232 and is used for vertically limiting the second clamp slider 232. Specifically, the clamp fixing block is arranged above the second clamp slider near one end of the clamping notch. The setting of the clamp fixing block can press the second clamp slider, so that one end of the second clamp slider can be reliably pressed down to avoid shaking during processing and causing the long section to be processed to shift. More specifically, a clearance notch can be set on the second clamp slider near one end of the clamping notch to facilitate tool processing.

[0026] The second fixture slider 232 includes a first fixture upper surface 2322 and a second fixture upper surface 2323. The horizontal height of the second fixture upper surface 2323 is lower than that of the first fixture upper surface 2322. When the second fixture slider 232 is in the first position, the fixture pressing block 242 abuts against the first fixture upper surface 2322 and vertically limits the second fixture slider 232. The first fixture upper surface 2322 is a plane or an inclined surface. Specifically, the first fixture upper surface is a slightly inclined surface, so that the downward pressure of the second fixture slider increases slowly when the second fixture slider is extended, and the second fixture slider is reliably pressed to prevent the second fixture slider from shaking during processing.

[0027] The clamp pressing assembly 24 includes a clamp adjusting block 243 and a clamp elastic block 244. The clamp pressing rod is against the clamp adjusting block 243. The clamp elastic block 244 is arranged between the clamp adjusting block 243 and the clamp fixing block 241. The clamp fixing block 241 is provided with an arc-shaped pressing sleeve 245. The setting of the clamp elastic block provides a certain elastic force and buffer force to avoid rigid contact damage to parts and components, thereby extending the service life of the product. The clamp elastic block is integrally formed of polyurethane material.

[0028] The present invention also includes a fixture positioning assembly 25, the fixture positioning assembly 25 includes a fixture top bead 251 and a fixture elastic member, the fixture core rod 22 is provided with a fixture positioning groove 221, the fixture elastic member has a movement tendency to drive the fixture top bead 251 to fit the outer surface of the fixture core rod 22, and the fixture top bead 251 is inserted into the fixture positioning groove 221 when the fixture core rod 22 is in the first position. In this way, the fixture core rod can be limited by the fixture top bead, so as to avoid the fixture core rod from over-moving and running the second fixture slide to move, and at the same time, to avoid the fixture core rod from falling during movement and affecting the horizontal limit of the long section to be processed.

[0029] The clamp frame 21 includes a clamp bottom plate 213 and a clamp upper plate 214. The clamp bottom plate 213 is provided with a clamp matching block 215 and a clamp core block 216 for the clamp core rod 22 to pass through. The clamp core rod 22, the clamp core block 216, and the second clamp slider 232 cooperate with each other to form the clamping gap 211. Such a structure makes the clamp positioning assembly, the clamp limiting assembly, and the clamp core rod easy to install and fix reliably. More specifically, the clamp core block and the clamp matching block are detachably connected to the clamp bottom plate.
