Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fasteners, and in particular to the technical field of cold heading devices. Background Technology
[0002] Cold heading machines are specialized equipment used primarily for the mass production of fasteners such as nuts and bolts. They utilize coiled and straight bar stock and employ the principle of secondary forging to produce various types of bolts and mechanical parts, including round heads, countersunk heads, semi-countersunk heads, internal hexagonal heads, and other non-standard head shapes. However, in most existing cold heading devices, the receiving box collects the bolts during the unloading process, making it difficult to promptly detect when the receiving box is full and replace it with an empty one. This requires frequent checks by staff, which is inconvenient.
[0003] Existing patent CN120460673A discloses a cold heading machine for easy bolt collection, including a cold heading machine body. A discharge adjustment device is installed on the left side of the cold heading machine body, and an adjustment collection device is set at the bottom of the discharge adjustment device. An auxiliary device is set on the outer surface and left side of the adjustment collection device. Although it can realize the electric switching of the receiving box, the switching timing still needs to be manually controlled. The operator needs to check the amount of bolts in the receiving box to determine whether to switch. At the same time, during the switching of the receiving box, since the two receiving boxes move synchronously in the same direction and there is a gap between the two receiving boxes, bolts will fall into the gap. Summary of the Invention
[0004] The purpose of this utility model is to solve the problems in the prior art and to propose a cold heading device for bolt processing with automatic switching of receiving boxes, which enables the receiving boxes to be automatically switched according to weight, and the bolts can always fall into the receiving boxes during the switching process.
[0005] To achieve the above objectives, this utility model proposes a cold heading device for bolt processing with an automatic switching receiving box, comprising a cold heading machine body, a discharge guide chute, a base, movable trolleys, push-pull devices, a weighing device, a mounting plate, a receiving box, an auxiliary plate, and a control device. Two movable trolleys are placed on the base, and two push-pull devices corresponding to each trolley are fixed to the base. The push-pull devices are connected to the corresponding trolleys, driving the trolleys to move horizontally. The two trolleys move in a straight line. A mounting plate is provided above the trolleys, and a weighing device is connected to the bottom of the mounting plate. The weighing device is fixed on a movable trolley. A receiving box is placed on the mounting plate. The top of the two receiving boxes with their adjacent sides are provided with upwardly inclined auxiliary plates. The auxiliary plates gradually move away from the receiving boxes from bottom to top. The adjacent sides of the two auxiliary plates are vertical planes. The movement trajectory of the two receiving boxes allows the adjacent sides of the two auxiliary plates to fit together. The push-pull device and the weighing device are both controlled by a control device. A cold heading machine body is provided on one side of the base. The discharge end of the cold heading machine body is provided with a discharge guide trough. The discharge end of the discharge guide trough is located directly above a receiving box.

Detailed Implementation
[0014] Example 1: See Figure 1 , Figure 2 This utility model discloses an automatic switching receiving box cold heading device for bolt processing, comprising a cold heading machine body 6, a discharge guide trough 60, a base 1, movable trolleys 2, push-pull devices 20, a weighing device 3, a mounting plate 4, a receiving box 5, an auxiliary plate 51, and a control device. Two movable trolleys 2 are placed on the base 1, and two push-pull devices 20, corresponding one-to-one with each movable trolley 2, are fixed on the base 1. The push-pull devices 20 are connected to the corresponding movable trolleys 2, driving the movable trolleys 2 to move horizontally. The two movable trolleys 2 move in a straight line. A mounting plate 4 is provided above each movable trolley 2, and the weighing device 3 is connected to the bottom of the mounting plate 4. Weighing device 3 is fixed on movable trolley 2. A receiving box 5 is placed on the mounting plate 4. The top of the two receiving boxes 5 with their adjacent sides are provided with upwardly inclined auxiliary plates 51. The auxiliary plates 51 gradually move away from the receiving box 5 from bottom to top. The adjacent sides of the two auxiliary plates 51 are vertical planes. The movement trajectory of the two receiving boxes 5 allows the adjacent sides of the two auxiliary plates 51 to fit together. The push-pull device 20 and weighing device 3 are both controlled by the control device. A cold heading machine body 6 is provided on one side of the base 1. The discharge end of the cold heading machine body 6 is provided with a discharge guide trough 60. The discharge end of the discharge guide trough 60 is located directly above a receiving box 5.
[0015] In order to facilitate the hoisting of the receiving box 5, the receiving box 5 is provided with several lifting lugs 50.
[0016] The push-pull device 20 is a hydraulic cylinder or an electric cylinder.
[0017] The control device can be installed on the base or set separately, or it can be integrated with the control box of the cold heading machine body 6.
[0018] Example 2: To ensure the smooth movement of the movable trolley 2, the base 1 is provided with two mounting slots 10 parallel to the direction of movement of the movable trolley 2. The mounting slots 10 are equipped with guide rails 11, and the movable trolley 2 includes I-beam wheels 21 that cooperate with the guide rails 11.
[0019] Example 3: In order to prevent the receiving box 4 from slipping off the mounting plate 4, the mounting plate 4 is provided with a number of positioning grooves 45, and the bottom of the receiving box 5 is provided with a number of positioning rods 55 that correspond one-to-one with the positioning grooves 45, and the positioning rods 55 are inserted into the positioning grooves 45.
[0020] Example 4: To promptly remind the operator to replace the receiving box 4, which is filled with enough nuts, the control device has an alarm module.
[0021] The working process of this utility model: In the operation of this utility model's automatic switching receiving box cold heading device for bolt processing, taking the initial state where the receiving box 5 on the left is below the discharge guide chute 60 as an example, the bolts produced by the cold heading machine body 6 fall into the receiving box 5 on the left through the discharge guide chute 60. The weighing device 3 detects the total weight of the mounting plate 4, the receiving box 5, and the bolts in real time and feeds the weight information back to the control device in real time. When the detected total weight reaches the preset value, the alarm module issues an alarm voice, and the right-side push-pull device 20 pushes the right-side movable trolley 2 to move to the left. After moving a certain distance, the two auxiliary plates 51 are brought together on their closest sides. Then, the right-side push-pull device 20 continues to push the right-side movable trolley 2 to the left. Simultaneously, the push-pull device 20 on the left pulls the movable trolley 2 on the left to move to the left. The two movable trolleys 2 move at the same speed. During the synchronous movement of the two movable trolleys 2, the bolt will fall directly into one of the receiving boxes 5 or directly onto the auxiliary plate 21 and eventually roll into the receiving box 5. When the movable trolley 2 on the right moves directly below the discharge guide chute 60, the movable trolley 2 on the right stops moving, while the movable trolley 2 on the left continues to move until it moves to the preset position. At this time, the operator can transfer the receiving box 5 on the movable trolley 2 on the left and place a new receiving box 5 on it. After the receiving box 5 is replaced, the operator manually clears the alarm module and issues an alarm voice.
[0022] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
