[0029] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment 1: In combination with Figures 1-6 , this embodiment discloses an automatic spring pressing device, including a base 1, a stamping seat 2, a stamping part 7, a positioning cylinder, a slider 4, a pressure applying driving part 5 and a supporting seat 6. Before the opening umbrella spring b is inserted, it is first sleeved on the positioning rod 3, and the pressure applying driving part 5 automatically compresses the opening umbrella spring b to make it enter the inner cavity of the middle rod a, and then cooperates with the stamping of the stamping part 7 to form a limiting structure. There is no need to use a gear pin which is not easy to process. This is beneficial to solving the problem that some existing opening umbrella springs b are prone to material jamming during installation, and is also beneficial to making the installation process more standardized and reducing the uncertainty of manual operation, thereby solving the problem of time-consuming and laborious manual operation.

[0031] The base 1 is a horizontal plate structure, and a vertically arranged bracket 11 is provided at its bottom. The function of the bracket 11 is to elevate the base 1 to create an installation space at the bottom, and another function is to facilitate the connection of the base 1 with external devices or equipment.

[0032] As Figure 4 shown, a stamping seat 2 with a "U" - shaped structure is provided on the base 1, and a stamping groove 21 is provided at the center position of the stamping seat 2. It is defined that the two lateral opening directions of the stamping groove 21 are in the front - rear direction.

[0033] The base 1 is provided with a horizontally arranged positioning rod 3 at the front side of the punching groove 21. The positioning rod 3 is composed of a stainless steel rod body with a diameter of 5 mm. One end of the front side of the positioning rod 3 is connected and fixed to the base 1 through a support seat 31, and the other end is a free end extending horizontally in the front-to-back direction to the rear side of the punching groove 21. The positioning rod 3 is provided with a chamfered structure at the free end, so that its free end is a rounded pointed end, which is convenient for the insertion of the spring. The positioning rod 3 is used to sleeve the umbrella opening spring b, and the free end of the positioning rod 3 can be horizontally inserted into the inner cavity of the middle rod a.

[0034] The base 1 is provided with a support seat 6 located at the rear side of the punching groove 21, and the front side of the support seat 6 has an "L"-shaped support structure. The support seat 6 and the punching groove 21 constitute a horizontal bearing structure of the middle rod a. In actual operation, the axial ends of the middle rod a can be respectively mounted on the punching groove 21 and the support seat 6, so that the middle rod a as a whole is in a relatively accurate front-to-back horizontal orientation, which is convenient for inserting the umbrella opening spring b.

[0035] Furthermore, a front-to-back position adjustment structure is provided between the punching seat 2 and the supporting seat 6 and the base 1. The front-to-back position adjustment structure is specifically a strip-shaped connecting hole facing forward and backward, and the punching seat 2 and the supporting seat 6 are assembled and fixed with bolts. Its function is to flexibly adjust the front-to-back position relationship between the punching seat 2 and the supporting seat 6 to meet the processing requirements of the rod a in various length specifications. In order to improve the connection stability, the number of the strip-shaped connecting holes is two arranged in parallel groups.

[0036] A slider 4 is movably connected to the positioning rod 3 , and a pressure driving member 5 is transmission-connected to the bottom of the slider 4 . The pressure driving member 5 can drive the slider 4 to slide back and forth along the positioning rod 3 .

[0037] Specifically, the base 1 is provided with a connecting groove 12 at the front side of the stamping seat 2. The connecting groove 12 is a through-hole structure parallel to the front-back direction. The connecting groove 12 runs through the base 1 longitudinally. The connecting groove 12 is located entirely below the positioning rod 3. The pressure driving member 5 is arranged at the bottom of the base 1. The output end of the pressure driving member 5 is connected with a connecting rod 41. The top of the connecting rod 41 extends to the top of the connecting groove 12 and is connected to the slider 4. In this embodiment, the pressure driving member 5 adopts a horizontally arranged cylinder, which is connected to an external air compressor and is connected with a manual button or a foot switch for convenient control. The telescopic rod at its output end can perform horizontal telescopic movement forward and backward, and is connected to control the connecting rod 41 to move forward and backward in the connecting groove 12, thereby controlling the slider 4 to slide forward and backward along the positioning rod 3. When the slider 4 moves backward, it will squeeze the umbrella opening spring b sleeved on the positioning rod 3. In order to ensure that each compression is accurate and reliable, an in-position sensor 51 is provided at the bottom of the base 1 to adapt to the forward and backward movable stroke of the connecting rod 41. It is a prior art, and its specific structure and working principle are not described here. Those skilled in the art can select and implement it from the prior art according to actual operating conditions.

[0038] Further, such asFigure 3 As shown, on one side of the slider 4 close to the stamping seat 2, there is an abutting member 42. The abutting member 42 is a sleeve structure with a diameter larger than that of the positioning rod 3 and smaller than the inner diameter of the middle rod a. Its function is to increase the structural hierarchy of the slider 4. During operation, the rear end of the abutting member 42 abuts against the front end of the umbrella-opening spring b. In this state, the umbrella-opening spring b can maintain a certain distance from the rear side wall of the slider 4. This distance enables the front end of the umbrella-opening spring b to be squeezed into the rear area of the stamping position after the subsequent abutting member 42 and the front end of the umbrella-opening spring b enter the inner cavity of the middle rod a, thereby ensuring that the limiting structure obtained after the stamping operation of the stamped part 7 can ensure that the umbrella-opening spring b remains inside the middle rod a without falling off.

[0039] It should be noted that the abutting member 42 and the slider 4 are detachable structures, which is beneficial for replacing the specification size of the abutting member 42 according to actual operation requirements or for maintenance after long-term operation wear.

[0040] Combined with Figure 4 , on the left and right sides of the stamping groove 21, there are stamped parts 7. The stamped parts 7 have pressing rods 71 that can horizontally expand and contract. The stamping seat 2 is provided with through holes (not shown in the figure) corresponding to the movement paths of the pressing rods 71. The through holes are horizontal through-hole structures in the left-right direction. The inner ends of the pressing rods 71 can enter the stamping groove 21 through the through holes to stamp the middle rod a, forming a limiting structure for the umbrella-opening spring b in the inner cavity of the middle rod a. Combined with Figure 6 , in the figure, the inner ends of the pressing rods 71 are taken as an example with a flat structure. The pressing rods 71 on the left and right sides can synchronously squeeze the middle rod a during operation, so that the side walls of the middle rod a are deformed under an appropriate stamping strength. Its left and right side walls collapse inward after deformation, forming an axial limiting structure, so that the internal umbrella-opening spring b cannot fall off. It should be noted that the stamped parts 7 adopt cylinders and are externally connected to manual buttons or foot switches for convenient control.

[0041] In the specific implementation process, combined with Figure 2 and 5 shown, first, the umbrella-opening spring b is sleeved on the positioning rod 3 from the back to the front, then the front end of the middle rod a is inserted into the free end of the positioning rod 3, and the middle rod a is placed on the stamping groove 21 and the supporting seat 6 to maintain a horizontal posture before and after, that is, the state in Figure 5 is obtained. Subsequently, control the pressure application driving member 5 to start working, so that the slider 4 moves backward, compresses the umbrella-opening spring b located on the positioning rod 3, and pushes the umbrella-opening spring b into the inner cavity of the middle rod a. After the extrusion is in place, control the stamped parts 7 to work, and the pressing rods 71 on the left and right sides act synchronously to stamp and form the middle rod a. As shown in Figure 6 , a anti-falling-off limiting structure for the umbrella-opening spring b is obtained. Subsequently, the pressing rods 71 move outward to reset, the slider 4 moves forward to reset, and the product can be taken out.

[0042] Embodiment 2: On the basis of Embodiment 1, combined withFigure 7 As shown in the figure, in this embodiment, in order to prevent the pressure rod 71 from excessively squeezing the middle rod a, a buffer spring 72 is abutted between the pressure rod 71 and the stamping seat 2. The telescopic direction of the buffer spring 72 is parallel to the stamping direction of the pressure rod 71. Since the middle rod a may have a certain degree of lateral displacement in the stamping groove 21, for example, it may deviate to the right. When the pressure rods 71 on both sides are stamping, the pressure rod 71 on the right side will contact the middle rod a in advance. If a pointed pressure rod 71 is used, in the case of rigid direct punching, the situation of unilateral excessive piercing and material jamming may occur, and even the positioning rod 3 located inside may be structurally damaged. However, the buffer spring 72 can avoid this situation. Through reasonable debugging, the buffer spring 72 can improve the stamping quality. In addition, the buffer spring 72 can also provide assistance when the pressure rod 71 is reset, thereby ensuring that the pressure rod 71 can be stably and quickly reset, reducing the waiting time of other components, and improving the operation efficiency.

[0043] Embodiment 3: On the basis of Embodiment 1, combined with Figure 8 As shown in the figure, in this embodiment, a limiting groove 63 is provided on the supporting seat 6 to further improve the accuracy of the placement position of the middle rod a. Specifically, the supporting seat 6 in this embodiment includes a front-side supporting plate 61. The supporting plate 61 and the main body of the supporting seat are connected by longitudinal strip holes and bolts, and can be adjusted in height position. Two baffles 62 are provided at the top of the supporting plate 61 and are distributed at intervals left and right. The space between the baffles 62 forms the limiting groove 63.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
