Description

Technical Field

[0001] This utility model relates to the field of cold heading mold technology, specifically a detachable multi-station cold heading mold. Background Technology

[0002] Cold heading is a new type of metal pressure processing technology with minimal cutting. It is a processing method that utilizes the plastic deformation of metal under external force and uses a mold to redistribute and transfer the metal volume to form the required parts or blanks. Cold heading requires specialized cold heading tools.

[0003] Patent CN222660005U discloses a multi-station cold heading mold. This prior art effectively adjusts the shaping block by setting an adjustment device, which reduces the need for replacing the entire mold when adjusting the cold heading process, as the mold is generally a single piece. This is too cumbersome, wastes the operator's time, and leads to low operator efficiency. This improves the practicality of the equipment.

[0004] However, some shortcomings still exist:

[0005] This existing technology simply makes it easier to replace the lower mold. However, in the actual cold heading process, the cold heading head (upper mold) is more prone to damage than the cold heading mold (lower mold) because it directly bears high-frequency impact and extreme stress. Furthermore, the upper mold of the device is installed in multiple pieces, so if one of them is damaged, an entire workstation will be scrapped, resulting in losses and reduced production efficiency.

[0006] Therefore, those skilled in the art have proposed a detachable multi-station cold heading die. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a detachable multi-station cold heading mold, which solves the problems mentioned above.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a detachable multi-station cold heading mold, including a mold mechanism, the mold mechanism including multiple mounting seats arranged in a straight line and evenly distributed, and an upper mold head is provided on the lower side of the mounting seats.

[0009] It also includes an installation mechanism, which includes a cavity opened in the center of each mounting base. Two strip grooves are symmetrically opened around the cavity on the lower side of the mounting base. A set of mounting plates is slidably arranged in the cavity. A set of inserts extending through the same side strip groove to the outside of the mounting base is installed on the side of the mounting plate. A gear is rotatably installed in the center of the cavity. A rack that meshes with the gear is installed on the side of the mounting plate.

[0010] The groove contains a strip plate that is compatible with it and connected to the upper mold head on the lower side. The side of the strip plate has a set of insertion holes that are compatible with the plug-in.

[0011] All mounting bases have a sliding drive plate on one side, and the side of the drive plate has a positioning hole for alignment with each set of plugs.

[0012] As a further technical solution of this utility model, a base is provided directly below all the mounting seats, and a lower mold adapted to each upper mold head is installed on the upper side of the base directly below each upper mold head.

[0013] As a further technical solution of this utility model, two telescopic damping rods with their lower ends connected to the base are symmetrically installed on the lower side of the mounting base, and a partition is installed on the upper side of the base between two adjacent mounting bases.

[0014] As a further technical solution of this utility model, two sliding rods are symmetrically installed on the inner wall of the cavity, penetrating the two mounting plates and slidably connected thereto, and a spring is sleeved on the sliding rod between the two mounting plates.

[0015] As a further technical solution of this utility model, a rectangular hole aligned with the rack is provided on the side of the mounting plate that is not on it.

[0016] As a further technical solution of this utility model, a motor with a drive end connected to the upper end of the gear shaft is provided at the center of the upper side of the mounting base, and a shock-absorbing pad is provided between the motor and the mounting base.

[0017] Beneficial effects

[0018] This utility model provides a detachable multi-station cold heading die. Compared with the prior art, it has the following advantages:

[0019] 1. A detachable multi-station cold heading die, wherein the upper die head in the die mechanism is mounted on the mounting base through the mounting mechanism, thereby making the upper die head detachable. If it is damaged, there is no need to scrap the station; it can be replaced directly, thus ensuring the production efficiency of the device and reducing economic losses. At the same time, the use of a motor as the power source for the clamping parts reduces the workload of the user during disassembly.

[0020] 2. A detachable multi-station cold heading mold, which uses a lifting drive plate to move all the mounting seats to perform cold heading operations. At the same time, if a certain upper die head is damaged, the mounting seat corresponding to the upper die head can be disconnected from the drive plate in conjunction with the mounting mechanism. Thus, when replacing the damaged upper die head, it does not affect the work of other stations, thereby further improving work efficiency. Attached Figure Description

[0030] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0031] like Figure 1-8 As shown, a detachable multi-station cold heading die disclosed herein may include:

[0032] Example 1:

[0033] like Figures 1-3As shown, the device includes a mold mechanism 1, which includes mounting seats 102 arranged in a row and evenly distributed. An upper mold head 103 is provided on the lower side of the mounting seat 102. A base 101 is provided directly below all the mounting seats 102. A detachable lower mold 104 that is adapted to each upper mold head 103 is installed on the upper side of the base 101 directly below each upper mold head 103. Cold-forged workpieces are placed into each lower mold 104. All the mounting seats 102 descend, causing all the upper mold heads 103 to descend, and the workpieces inside are cold-forged in cooperation with the lower mold 104. Afterward, all the upper mold heads 103 rise and move out of the lower mold 104, and the formed workpieces can be taken out.

[0034] like Figures 4-5 As shown, it also includes an installation mechanism 2, which includes a cavity opened in the center of each mounting base 102. Two strip grooves 201 are symmetrically opened on the lower side of the mounting base 102 around the cavity. A set of mounting plates 203 are slidably arranged in the cavity. A gear 204 is rotatably installed in the center of the cavity. A rack 205 that meshes with the gear 204 is installed on the side of the mounting plate 203. When the gear 204 rotates, it drives the two mounting plates 203 to move closer to each other through the two racks 205. When the gear 204 reverses, it drives the two mounting plates 203 to move away from each other through the two racks 205.

[0035] like Figures 4-5 As shown, a set of inserts 206 are installed on the side of the mounting plate 203, extending through the same side strip groove 201 to the outside of the mounting base 102. A strip plate 207 is provided in the strip groove 201, which is adapted to it and connected to the lower upper mold head 103. A set of insertion holes 208 adapted to the size of the inserts 206 are opened on the side of the strip plate 207. When the inserts 206 on the mounting plate 203 are inserted into the insertion holes 208 of the strip plate 207, the upper mold head 103 can be fixed on the mounting base 102, and the upper mold head 103 can be provided with the stability required for the process. At the same time, the moving mounting plate 203 can drive the inserts 206 to move.

[0036] like Figure 5 As shown, two slide rods 202 are symmetrically installed on the inner wall of the cavity, penetrating the two mounting plates 203 and slidably connected to them. A spring 210 is sleeved on the slide rod 202 between the two mounting plates 203. The moving mounting plates 203 slide on the slide rod 202. At the same time, the spring 210 can suppress the movement of the two mounting plates 203, avoid vibration during cold heading that causes the mounting plates 203 to become displaced, and reduce the wear between the gear 204 and the rack 205.

[0037] like Figure 5 As shown, a rectangular hole 211 aligned with the rack 205 is provided on the side of the mounting plate 203, which is not on it, to prevent the mounting plate 203 from affecting the movement of the rack 205 not on it when the two mounting plates 203 approach each other.

[0038] like Figure 8 As shown, a motor 209 is provided at the upper center of the mounting base 102, with its drive end connected to the upper end of the shaft of the gear 204. A shock-absorbing pad 212 is provided between the motor 209 and the mounting base 102. The motor 209 can drive the gear 204 to rotate. The shock-absorbing pad 212 between the motor 209 and the mounting base 102 can reduce the vibration of the motor 209 during the cold heading process.

[0039] like Figure 2 and Figure 6 As shown, each mounting base 102 has a sliding drive plate 3 on one side. The side of the drive plate 3 has a positioning hole 4 on one side of each set of plug-in 206, and the size of the positioning hole 4 is adapted to the plug-in 206. This allows the set of plug-in 206 on the same side of the mounting base 102 as the drive plate 3 to be inserted into the aligned positioning hole 4. The drive plate 3 is then connected to a vertically downward cylinder. The extension and retraction of the cylinder can drive the drive plate 3 to move up and down, thereby driving the mounting base 102 to move up and down. At the same time, the plug-in 206 on the mounting base 102 is not inserted into the positioning hole 4 of the drive plate 3, so that the mounting base 102 can be disconnected from the drive plate 3. The damaged upper mold head 103 can be replaced without affecting the normal operation of other workstations.

[0040] like Figure 2 and Figure 3 As shown, two telescopic damping rods 105 with their lower ends connected to the base 101 are symmetrically installed on the lower side of the mounting base 102. A partition plate 106 is installed on the upper side of the base 101 between two adjacent mounting bases 102. When the drive plate 3 is disconnected from the mounting base 102, the telescopic damping rods 105 can support the mounting base 102. At the same time, the partition plate 106 can protect the hands of the workers when they replace the damaged upper mold head 103 or lower mold 104.

[0041] In summary, by inserting a set of plugs 206 on the same side of the mounting base 102 as the drive board 3 into the aligned positioning holes 4, the drive board 3 is connected to the vertically downward cylinder. The extension and retraction of the cylinder can drive the drive board 3 to move up and down, thereby driving the mounting base 102 to move up and down.

[0042] When a certain upper die head 103 is damaged, the motor 209 above it drives the gear 204 to rotate, causing the two mounting plates 203 to move closer together. This, in turn, causes the two sets of inserts 206 to move closer together. First, the inserts 206 disengage from the positioning holes 4, thereby releasing the connection between the mounting base 102 corresponding to the damaged upper die head 103 and the drive plate 3. Then, the drive plate 3 continues to rise and fall to allow other workstations to operate normally. The motor 209 continues to drive the gear 204 to rotate, causing the two sets of inserts 206 to fall out of the insertion holes 208, releasing the fixation on the upper die head 103. The damaged upper die head 103 is then removed, and a new one is installed. The two strip plates 207 of the upper mold head 103 are inserted into the two strip slots 201. When fully inserted, the plug 206 is aligned with the insertion hole 208. Then, the motor 209 drives the gear 204 in the reverse direction to make the two sets of plugs 206 move away from each other and be inserted into the corresponding insertion holes 208, thus fixing the upper mold head 103 to the mounting base 102. After that, when the drive plate 3 rises to the positioning hole 4 and aligns with the plug 206, the motor 209 continues to drive the gear 204 in the reverse direction to make the set of plugs 206 on the same side as the positioning hole 4 be inserted into the aligned set of positioning holes 4. The mounting base 102 is then reconnected to the drive plate 3.

[0043] Example 2:

[0044] like Figure 7 As shown, a circular hole 5 is provided on the lower side of the base 101 directly below each lower mold 104. An electric push rod 6 is installed in the center of the lower side of the lower mold 104 and is located in the circular hole 5. The telescopic arm end of the electric push rod 6 extends into the mold of the lower mold 104 and is equipped with a push plate 7 that matches it. After cold heading is completed, all electric push rods 6 extend and drive the push plate 7 to rise, pushing out the cold-headed workpiece in the lower mold 104, which speeds up the workpiece unloading and also avoids the situation where the workpiece is too tightly connected to the lower mold 104 and is difficult to remove.

[0045] The working principle of this utility model:

[0046] Connect the drive plate 3 to the vertically downward cylinder, and place the cold-forged workpiece into each lower mold 104. The cylinder extends and drives all the mounting seats 102 to descend through the drive plate 3, and at the same time drives all the upper mold heads 103 to descend. Each upper mold head 103 cooperates with the lower mold 104 directly below to cold-forge the workpiece inside. After that, all the upper mold heads 103 rise and move out of the lower mold 104, and the formed workpiece can be taken out.

[0047] When a certain upper die head 103 is damaged, the motor 209 above it drives the gear 204 to rotate, causing the two mounting plates 203 to move closer together. This, in turn, causes the two sets of inserts 206 to move closer together. First, the inserts 206 disengage from the positioning holes 4, thereby releasing the connection between the mounting base 102 corresponding to the damaged upper die head 103 and the drive plate 3. Then, the drive plate 3 continues to rise and fall to allow other workstations to operate normally. The motor 209 continues to drive the gear 204 to rotate, causing the two sets of inserts 206 to fall out of the insertion holes 208, releasing the fixation on the upper die head 103, and allowing the damaged upper die head to be removed. Remove head 103 and insert the two strip plates 207 of the new upper mold head 103 into the two strip slots 201. Then, the motor 209 drives the gear 204 in the reverse direction to make the two sets of plug-in 206 move away from each other and be inserted into the corresponding insertion holes 208, thus fixing the upper mold head 103 to the mounting base 102. Then, when the drive plate 3 rises to the positioning hole 4 and aligns with the plug-in 206, the motor 209 continues to drive the gear 204 in the reverse direction to make the set of plug-in 206 on the same side as the positioning hole 4 be inserted into the aligned set of positioning holes 4. Then, the mounting base 102 is reconnected to the drive plate 3.
